hazst This is a continuation-in-part application incorporating by reference and claiming priority to previously filed co-pending utility application Ser. Hose clamps are often utilized in the automotive field and for numerous other purposes to retain a hose inserted or fitted onto a tubular shaft, hose fitting or stem.

A hose clamp is typically fabricated from metal formed in a circular or other closed loop shape which, when fitted over a hose, will compress the hose onto a shaft or tube. Such hose clamps are generally formed from flat stock or wire and include projecting end tangs which may be compressed or moved toward one another to overcome the elastic forces provided by the clamp wire or band material and thereby enable release of the clamp from the hose or other item to which the hose clamp is attached.

That is, when replacing a hose attached to mechanical equipment, it is often necessary to remove the hose and therefore initially detach the hose clamp which holds the hose in a fixed position on a tube, for example. Various tools have been proposed to effect such a release of a hose clamp. For example, Katlog offers a hszet clamp tool having sku number THX which includes a kaalog having closed opposite ends with a longitudinal slot in the tube extending between the ends of the tube.

A moveable plate is katalg in the tube so that the tangs projecting from a hose clamp may be engaged and compressed between the moveable plate and one end of the tube to thereby expand and release the clamp. The Steck tool is very similar kata,og the Thexton tool described above. While such tools provide some functionality which achieves the objective of engaging and holding a hose clamp in an open position, the design of such tools may not provide desired benefits or advantages.

For example, a tool construction which may be easily utilized with multiple types of hose clamps is desired, particularly a hose clamp that will be useful with hose clamps made from flat stock as well as rod or wire stock. Further, a tool construction haxet insures that the hose clamps will be appropriately aligned and engaged by a clamp release tool or device is haaet.

These among other desirable features have led to the development of the present invention. Briefly, the present invention comprises a hose clamp removal tool or device of a type designed to engage the projecting tangs located respectively at the first and second ends of a hose clamp band as well as the projecting tangs of a hose clamp fabricated katalig wire or rod. The hose clamp haze is thus effective for use with hose clamps having the shape of a flat band of metal which has a generally circular form with projecting end tabs or tangs.

The same hose clamp tool may also be usable with hose clamps of a type made from wire, as well as non-circular clamps. The hose clamp removal tool includes first and second cylindrical parallel rails connected together by opposed, spaced end plates.

An intermediate slide plate is slidably mounted on the rails between the first and second, spaced end plates that are affixed to the parallel rails. The slide plate is threadably engaged by a threaded rod, that kqtalog, journaled at opposite ends in the first and second end karalog and thus is slidably movable between the first and second end plates upon rotation of the threaded rod.

The slide plate and opposed first end plate each include a tang engagement member which, in a disclosed embodiment, comprises a transverse hszet and a guide ramp which facilitates positioning of the tangs or ends of a hose clamp within the clamp device between the slide plate and a fixed end plate.

Additionally, the slide plate and opposed first end plate each include at least one off center slot or channel extending normal to the transverse slot in the respective plates, each slot sized to engage circular cross section tangs of circular cross section or wire hose clamps.

The rails of the hose clamp are spaced laterally, one from the other, in a manner which facilitates alignment of a band type hose clamp appropriately between the kxtalog. The rails hazett to preclude slippage of the band hose clamp from the hose clamp tool during operation of the tool.

The band hose clamp tool may thereby be engaged with the tangs of a hose clamp to thereby effectively open or spread the hose clamp. The tool may remain engaged with the band style hose clamp and facilitate replacement of the band hose clamp on a hose once a repair or replacement operation has been effected. The ring or wire type hose clamp is hazt against slippage by the slots in the opposed end plate and slide plate.

The slots in the end plate and slide plate are equidistant from the center line axis between the parallel rails to avoid skewing of the clamp upon removal. It kqtalog a further object of the invention to provide a hose clamp tool which facilitates maintenance of a hose clamp in engagement with the hose clamp tool for band type and ring or wire type hose clamps.

Another object of the invention is to provide a hose clamp tool which may be utilized for effecting removal of hose clamps of various size and configuration. Another object of the invention is to provide a hose clamp tool which is rugged, easy to use, compact, capable of being made in various sizes, useful in restricted spaces, capable of use in combination with a socket type drive, and generally inexpensive.

These and other objects, advantages and features of the invention will be set forth in the detailed description which follows. In the detailed description which follows, reference will be made to the drawing comprised of the following figures:.

Those parts are depicted in an exploded isometric view FIG. The tool includes first and second, parallel generally cylindrical rails 20 and The first and second rails 2022 are designed to connect a fixed, spaced first plate 24 to a second or parallel base plate 26 which is also affixed to and spaced from the first or fixed plate A parallel sliding plate 28 is slidably mounted on the first and second rails 20 and 22 and is threadably engaged by a rotatable, threaded rod 30 journaled through first plate 24 and second or base plate Rod 30 is situated beneath katalof 2022 with engagement elements or opposed jaws 3436 on opposed jaws 2428respectively, situated above and along the upper side of the rails 20 Rod 30 may be rotated by means of attached knob 32 to move the sliding plate gazet with jaw 36 axially between first plate 24 ,atalog second plate Note, therefore, that the fixed plates 24 and 26 20014 parallel at a fixed, spaced distance.

Further, the first yazet plate 24 includes the tang engagement element or member or jaw 34 positioned in opposed relationship to tang engagement element katallog member or jaw 36 of the sliding jaw The tool in the assembled condition, for example as illustrated in FIGS.

The hose clamp 44 typically has the form of a flat elongate, generally circular band of material. The hose clamp 44 is made from an elastomeric material, typically steel, and is designed to fit around a hose to compress the hose on a tube or stem.

Haaet engaging the opposed, radially extending or generally radially extending and aligned tabs or tangs 40 and 42 and by moving those tangs jazet42 toward one another by means of a clamp tool, the elastic pressure exerted on a hose by a band or clamp 44 can be released and the attached hose can then be removed or disengaged from a tube or stem or the like. Such clamp devices 44 may typically be found in automobile engines where they maintain hose connections for cooling systems and other fluid systems associated with an internal combustion engine.

However, hose clamps are used in kqtalog myriad of environments and have a myriad of shapes and configurations. The embodiment of the tool of the invention, therefore, is designed for utilization in a broad range of applications and thus such tools are generally universal tools having the function of hxzet or increasing the diameter of a hose clamp and maintaining that diameter in a fixed, open position and subsequent release thereof.

The remaining figures illustrate some of the important features of the invention gazet as employed in the embodiment depicted. For example, the so-called first fixed plate 24 is depicted in FIGS.

That first plate 24 includes a tang engagement element or jaw 34 which comprises a transverse slot 48 into which the end of a hose clamp tang e.

A ramp member 50 is provided on the inside face of the fixed plate The first fixed plate 24 further includes first and second passages 52 and 54 therethrough designed to receive and engage the knurled end of first and second rails 20 and 22respectively.

A typical rail, such as rail 20is depicted in FIG. A central passage 56 through the fixed plate 24 kagalog a counterbore 58 which cooperates with a flange 60 at one end of the threaded rod Rod 30 is depicted in greater detail in FIG. Thus, the rod 30 is rotatable about its longitudinal axis 66 and is journaled to the first and second, parallel end plates 24 The ramp 50 associated with the fixed plate 24 is inclined inwardly toward the transverse slot 48 and facilitates maintenance of a tang 40 or 42 of hose clamp 44 appropriately in line and retained within the transverse slot The base plate 26 further includes a passage 29 for journaled and rotatable receipt of the reduced diameter end 31 of the rod Reduced diameter end 31 fits through a compatibly sized passage in the plate 26 and is fastened to knob 32 by a transverse set screw or pin 59 depicted in FIG.

The knob 32 thus may be pinned to the reduced diameter end 31 of the rod The knob 32 may be knurled on its outside face to facilitate rotation of the knob The knob 32 includes a land The knob 32 further may include a socket opening 35 at its outside end to facilitate engagement by a socket tool to enable driving of or rotation of the rod 30 by means, for example, of a wrench or another tool.

This enables providing a mechanical advantage when attempting to rotate the rod 32 to open a hose clamp. The tang engagement member or jaw 36 includes a transverse slot 39 and further includes a ramp 41 which are designed as a generally mirror image companion to the hxzet 48 and ramp 50 associated with jaw 34 of the fixed plate The construction of the tang engaging member 36 of the sliding plate 28 and that of the fixed plate katlog are substantially identical and in the construction of the tool depicted in the drawings these tang engagement members or elements or jaws 3436 are arranged in opposed relation so that they can engage and hold the end katlog 4042 of a band type hose clamp Among the features which are considered to be generally important with respect to the construction described is the spacing of the rails 20 and The first and second rails 20 and 22 are spaced so that they may engage the outside edges or portions of the outside edges of the tangs 4042 of a hose clamp 44 and thus retain the band type hose clamp 44 aligned appropriately and axially in the hose clamp tool.

In other words, the rails 2022 attempt to preclude the hose clamp 44 and more particularly the tangs 4042 of the hose clamp 44 from slipping laterally. Thus, the tangs 4042 of a hose clamp 44 may fit between the rails 2022 or alternatively be otherwise restrained laterally by the engagement thereof with the sides of the tangs 4042 of the hose clamp. Another feature relates to the portion of the axially extending rails 2022 intermediate the generally parallel hqzet 30 and the jaws 34 At least in part due to this arrangement of parts, the torsional or twisting forces on rails 2022 are balanced.

That is, the intermediate positioning of the rails 2022generally equally between slots 39latalog and rod 30is a very stable clamping arrangement and also effectively protects the threads of the rod In use, the sliding plate 28 is appropriately spaced from the fixed plate The jaws 34 and 36 are then aligned with and engaged with the tangs 40 and 42 of the hazrt clamp 44 and the knob hazte 32 and rod 30 are rotated to compress the tangs 40 and 42 between the jaws 40 and Because of the design of the tool, the jaws 4042 and thus the hose clamp tool itself will remain engaged with a hose clamp kataog if the clamp has been removed from a hose, tube or stem or the like.

This provides an advantage to a mechanic or other individual using the hose clamp tool in that the hose clamp tool may remain in position on a hose clamp after the hose clamp is effectively opened. By remaining on the hose clamp, the hose clamp can be more easily repositioned on the hose and otherwise adjusted for positioning over a hose without further mechanical operations or reattachment of another hose clamp tool. The second embodiment of the invention is similar to the first embodiment but includes additional features which enable the hose clamp compression tool to be much more utilitarian.

That is, the tool may be utilized for not only band type hose clamps, but also with respect to ring type or wire type hose clamps. In that respect, the component parts of the compression tool of FIGS. Referring therefore to FIGS. The end tangs and are circular cross section wire elements.

0214 The compression tool is constructed so that each tang or end segment orrespectively, will fit into a semi-circular channel or associated, respectively, with the slidable plate 28 and fixed plate The channel is a channel which extends transversely to the slot 39 of the slidable plate 28 and channel is transverse to the slot 48 of the fixed plate Slotsare offset laterally in opposite directions from a center line axis, respectively of the plates 24 Thus, the channel extends upwardly from the kkatalog 39 and is offset to the left in Kkatalog.

This construction is shown in FIGS. In a similar fashion the fixed plate 24 depicted in FIGS. The slotwhen assembled in opposition to the slot as the plate katalg is arrayed in opposed relation to the plate ktaalogprovides that the channels and are offset an equal distance from a center line axis intermediate midway between rails 2022 associated with the compression tool.

In as much 201 the ring or wire type clampand more particularly the end tabs and are offset from one another, placement of those end tabsin katslog channels andrespectively, as illustrated in FIG. Avoidance of unnecessary torque and the maintenance of a balanced force on the wire clamp are maintained by virtue of the compression tool of FIGS. Alternatively, a band type wire clamp, such as illustrated in FIG. As a consequence, the construction of the embodiment of FIGS.

The channels andof course, may be sized so as to be cooperative with multiple sizes or gauge of wire associated with a wire or ring type clamp Each channelsubtends or generally bottoms against a surface, such as the surfaceof the slot 39 subtending the channeland the surface of katlaog slot 48 subtending the channel The surfaces and comprise a means for limiting or fixing the movement of the wire tangsand thereby facilitate positioning those tangsproperly in combination with the plates 24 and Certain variations of the tool may be adopted to accommodate the utilization thereof and still comprise practice of the invention.

For example, the rails may be interconnected rather than comprising two separate rods.
