Application August 18, 1948, Serial No. 44,899

1 Claim. l

The present invention relates generally to holding devices, and more particularly to a readily releasable handle construction finding particular adaptation to solder, paddles, reversible files, and the like.

An object of the present invention is to provide a novel releasable handlev construction and its adaptation to solder paddles, reversible files, and the like.

Another object is to provide a novel releasable handle construction which is firmly anchored-t the working portion of the device to which it is applied when in operating position in respect thereto in a manner substantially eliminating relative lateral movement.

Other objects are to provide a novel handle construction for solder paddles, and the like, which is readily and easily applied and removed, which is inexpensive to make, which is adapted to render long service without requiring anymaintenance, and which may be applied to and removed from a working member with minimum instruction.

The foregoing and other object and advantages are apparent from the following description taken with the accompanying drawing, in which:

Fig. 1 is a plan view of a handle construction formed in accordance with the teachings of the present invention applied to a. solder paddle;

Fig. 2 is a side elevational view thereof;

Fig. 3 is an enlarged vertical transverse crosssectional view on the line 33 of Fig. 2, portions being shown in end elevation;

Fig. 4 is an enlarged fragmentary longitudinal vertical cross-sectional view taken on substantially the line 4-4 of Fig. 1;

Fig. 5 is an enlarged transverse vertical crosssectional view on substantially the line 55 of Fig. 1;

Fig. 6 is an enlarged fragmentary plan View of the recessed portion of the solder paddle which receive the handle construction;

Fig. 7 is an end view of the solder paddle looking towards the open end of the handle construction receiving recess; and

Fig. 8 is a fragmentary enlarged longitudinal vertical cross-sectional view through the attaching end of the handle construction, the hinged clamping or jaw member being shown in released position.

Referring to the drawing more particularly by reference numerals, I0 indicate generally a solder paddle incorporating a handle construction [2 and a paddle or work member I4 includ ing the concepts of the present invention.

The handle construction 52 includes an attaching flat-bottom base member it, formed integral with which is ta hand-grip supporting arm it to which is secured a hand-grip member 28,

preferably of Wood, by suitable screws 22. The hand-grip supporting arm I8 includes an arcuate neck portion 24 formed on an arc of ninety degree so that the hand-grip member 20 is disposed in an offset plane parallel with the work member l4.

The attaching base member It includes an integral dependingtransverse flange orstationary jaw 26 which forms an acutev angle with the bottom 28 of the-member l5. Also formed integral with the member I5 is. a longitudinally extending boss 35 having a threaded longitudinally extending well 32 which receives a suitable screw 34 having a knurled head. A movable jaw member 36 is pivotally mounted. on a pin, 33. supported by a central hinge leeveMl formed-integral with the arcuate neck portion 24. The jaw member 35 includes spaced. integral hinge sleeves 42 between which is disposed the hinge sleeve ie. The movable member 36 also includes an integral flange 44 whichis at substantially ninety degrees thereto. Between the flange 44 and its hinge connection, the movable member 36 includes a slot 48 through which the screw 34 extends. It is manifest that the flange 44 is in opposed relation with the flange 26.

The work member M has a longitudinal recess 48 in the upper surface adjacent one end (Figs. 6 and 7). The recess 48 is of shallow depth and is defined by side walls 56. A transverse channel 52 is formed at the inner end of the recess 48 and extends into the body of the work member 4 at an acute angle to the surface of the recess 48. Extending beneath the recess 48 from the end of the work member !4 is a channel 54.

In Fig. 4 the relationship of the handle construction l2 and the work member I4 is clearly illustrated. The base member I6 fits into the recess 48 with the flange 26 extending into the channel 52. The flange 44 of the movable member 35 extends into the channel 54 and is securely maintained in position by the screw 34, the head of which bears against the movable member 36. Both the snug fit of the base member 16 in the recess 48 between the walls 50 and the clamping engagement of the flanges 26 and 44 in their respective channels 52 and 54 insures a rigid connection between the handle construction l2 and the work member l4.

Manifestly, the handle construction 12 may be quickly removed from the work member M by loosening the screw 34 and pivoting the movable jaw member 35 re arwardly to some such position as that shown in Fig. 8, whereupon the flange 26 may be removed from the channel 52.

As has been pointed out above, the present handle construction l2 finds particular adaptation to a solder paddle, the Work member of 'which is normally of wood which becomes burned in its use and requires replacementatrelatively *3 frequent intervals. Another application is a fiat file of the type which employs an offset handle. Manifestly, the handle construction is adapted for other uses.

It is apparent that there has been provided a handle construction and a particular adaptation which fulfill the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawing have been given by way of illustration and example. It is also to be understood that changes in form of the elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the art, are contemplated as within the scope of the present invention which is limited only by the claim which follows.

What is claimed is:

A work tool comprising, in combination, an expendable paddle-like work member, such as a trowel, spatula, or the like, which must be supported from a rearward end for proper use thereof, a longitudinal recess in said work member extending forwardly from said rearward end, said recess having a horizontal plane surface and parallel vertical sides, a first transverse channel formed at the forward end of said recess and extending downwardly and rearwardly therefrom, a second transverse channel formed at the rearward end of said work member and extending horizontally forwardly therefrom, a handle construction releasably secured to said work member including a base having a lower horizontal plane surface and parallel vertical sides snugly disposed 3 in said recess thereby eliminating relative lateral movement between said work member and said handle construction, said base including a transverse hook portion extending downwardly and rearwardly from a forwardly disposed end thereof, said hook portion engaging a wall of said first transverse channel in said work member, a handle grip support extending upwardly and rearwardly from said base, a member pivotally connected to said grip support, said pivotally mounted member having a transversely extending flange releasably engaging a wall of said second channel in said work member, and a screw extending through said pivotally mounted member and anchored in said base for drawing pivotally mounted member into position engaging a wall of said second channel to secure said handle construction on said work member.
