BEL-TING TOOL.

Specification of Letters Patent.

Patented July 11, 1922.

Application filed nine in, 2920. Serial No. asters.

To all whom it may comm m:

Be itv known that I, ANTONIO G. B'AVA, a subject of the King of Italy, residin at city and county of San Francisco and tate of California, have invented a.- new and useful Improvement in Belting Tools, of which the following is a. specification.

This invention relates to a belting tool.

It is the principal object of the present invention to provide as tool which may be used tosecure the ends of belting together wnd mrticularly adapted for cutting and stapling the ends of round belt cords in position relative to each other so that a continuous belt will be provided.

The present invention contemplates the use of a device having three 'ews hinged together at one end and adapts to be separately moved to cut belting, thereafter grip the ends of e belt in abutting relation to each other, then force a staple through the belt and crimp the same in position.

The invention is illustrated by way of example in the accompanying drawings, in which:

Figure 1 is aview of the belting tool in elevation. with the pressure jaw turned back and with parts of the clamping jaw broken away to more clearly show the position of belting secured thereby.

Fig. 2 's a view in side elevation showing the parts disclosed in Fig. 1 and further indicating the stapling operation.

Fig. 3 is a view in section through the device as seen on the lines 3-3 of Fig. 2 showing the manner in which the staple is forced through the belt.

Fig. 4 is another view showing the staple as it has been completely forced through the belt and particularly bent over.

Fig. 5 is a view in section through the tool as seen on the line 5--5 of Fig. 2, showing the manner in which the staple is set in position.

Fig. 6 is a view showing parts as illustrated. in Fig. 5 disclosing the completion of the setting operation.

Referring more particularly to the drawings, 10 indicates a. clamping jaw which is formed with a handle 11. This jaw is pro vided with a hinge bar 12 at its end which clamping action of the two jaws l0 and 14.

The second or intermediate clamping jaw 14 is formed with central longitudinal openings 17 which as shown in Fig. 1 gradually enlarges toward the handle of the jaw. thus accommodating larger staples 18 for the larger sizes of belting. Grooves 19 extend along the opposite side walls of the opening 18 and: act as guides for the staples. These groovesare so disposed as to direct the points of the staples through the center of the belting held within the recesses of the clamping jaws, thus insuring that the staples will be oent'ral'l driven through the belting. Directly he ow the guide slots 1'9 and formed within the lower jaw 10 is a series of recesses 20 into which the points of the staples sire forced, after having passed through the belting and by which the ends of the staples are bent so as to prevent their removal from the betting. It is to be understood that these staples are of special shape as shown in Fig. 3 amd that by reason of their straight sides and tapered points it is possible to easily inturn them as they are forced down along the inclined faces of the recesses 20.

The staples are forced through the belting by means of a pressure lever 22. This lever is pivoted upon a pin 23 to the upper end of the hinge member 12 and may be swung toward and away from the clamping jaws and in the same plane of swinging movement as they pursue; The )ressure jaw 21 is secured to the face of the ever 22 and is adapted to be passed into the open- 18 in the secondary clamping jaw 14. The shape of the block is substantially the same as that of the opening 18. thus providing a pressure surface agreeing with the flat up per face of the staple to be set. At the end of the clamping jaws near the handles recesses 24. are provided. These recesses are adapted to accommodate the belting after the staple has been passed therethrough and from gripping means so that an extension 25 may be brought down against inturning ends of the staple to cause them to be satisfactorily set as more clearly shown in Fig. 6.

For convenience a cutting blade 26 is secured to the pressure lever 22 and is adapted to move down alongside of the member 14 so that the belting may be easily cut. A centering blade 27 is also provided and is adapted to extend across the grooves a, b, c, and d of the lower clamping jaw. This makes it possible to center the joint of the belt directly in the center of the staple.

In operation of the present invention the belting is cut to a suitable length by means of the cutting blade 26, after which the ends of the belt are placed in one of the recesses in the lower clamping jaw 10 with their end faces abutting against the opposite sides of the centering blade 27. The secondary clamping jaw 14 is then brought down over the belt and the two jaws locked in relation to each other by a ring member 28. The staple ,18 is then placed in the slots 19 of the secondary clamping jaw and its points directed downwardly against the belting. The pressure jaw is then forced down and will drive the staple through the belting and force its points into the narrow recess 20 where the points will be inturned as more clearly shown in Fig. 4. After this has been accomplished the jaws 10 and 14 are opened and the belt turned over and laced with the flat portion of the staple within recess 24 of the clamped jaw 10. The belt is again clamped in position and pressure exerted upon the inturned points of the staple by the projection 25 of the pressure block 21.

It will thus be seen that the present invention provides a very compact tool by which belting may be cut and securely stapled at its ends, said tool operating in a manner to insure that the staple will pass directly through the transverse center of the belting and will thereafter be clinched in a secure manner.

While I have shown the preferred form of my invention as now known to me, it will be understood that various changes in the construction, combination and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A belt stapling device comprising a fixed jaw with transverse belt receiving grooves. a clamping jaw pivotally connected to the fixed jaw and having portions engageable with the belt ends disposed within the grooves, and a pressure lever fulcrumed near the first named pivot and movable to force a staple through the ends of a belt placed in one of said grooves.

2. The combination in a belt stapling apparatus, of a fixed and a movable jaw, transversely grooved to receive the contiguous belt ends, said movable jaw having a longitudinal vertical opening, and a pressure lever having an element extending into the opening and acting to drive the staples through the abutting belt ends.

3. The combination in a belt stapling device, of a fixed and a movable transversely grooved jaw to receive and clamp contiguous belt ends, said movable jaw having an outwardl divergent recess with vertical grooves to receive the staples, a movable lever having a portion insertable within the divergent recess in the movable jaw to engage the staples and force the same through the contiguous ends of the belt.

4. In a belt stapling apparatus, a fixed and a movable transversely grooved jaw, said movable jaw having a recess with vertical staple guiding grooves, a belt centering blade, and a movable lever with projecting means to enter the recess and drive the staples, said fixed jaw having a curved groove into which the staple ends are received and by which they are bent towards each other.

5. A tool of the class described comprising a pair of cooperating clamping aws having transverse recesses in the adjacent faces thereof within which belting may be held, one of said jaws being formed with a grooved recess therethrough to receive a staple and a pressure member pivoted relative to the first named jaw members and adapted to force the staple through the opening and into a clinching position through the belting.

6. X device of the character described comprising a pair of pivotally connected and co-operating clamping jaws having transverse recesses in adjacent fares thereof for receiving contiguous belt ends and securing the same therein, one of said mem hers having an opening formed therein, a pressure member movable relatively to the jaw members and having a projection adapted to enter the opening in thejaw member and engage the staples and force them through the belt ends, the other of said jaw members being provided with a recess formed and positioned in a manner whereby the staple points will be brought in clinching position when forced through the belt ends.

7. A tool of the class described comprising a pair of cooperating clamping jaws having transverse recesses in the adjacent faces thereof within which belting may be held, one of said jaws being formed with a recess therethrough to receive a staple, a pressure member pivoted relative to the first named jaw members and adapted to force the staple through the recess and into a clinching position through the belting, said clamping jaw being provided with guide grooves along the opposite sides of the recess through the clamping jaw for guiding the staple through the center of the belting, and means for nesses.
