' BELT-QLACING moon.

Be it known that we, Ismon M.'JA( JOBS and WILLIAM CRAMER, citizens of the United States, residing, respectively, at the city of Kansas City, in the county of Jackson and State of Missouri, and at the city of St.

Louis, State of Missouri, have invented certain new and useful Improvements in Belt- Lacing Tools, of which the following is a specification. I

. This invention is a tool for applying belt lacings to belts. It is especiallyintended and adapted for use in connection with a well-kriown and standard form of staples used for belt lacings.

An object of the invention is to provide a tool which can be constructed at a minimum cost, and which will be eflicient in use.

A further object of the invention is to provide a tool in which the belt is securely clamped against displacement so that the staples will be properly placed therein.

A further object is to provide slmple clamping means to hold the belt, and also the staples. p

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a top plan view;

Fig. 2 is a side elevation;

Fig. 3 is a side elevation with a hammer about to clench the staples;

Fig. 4 is a longitudinal vertical sectlonal view;

Fig. 5 illustrates a staple in a piece of belting;

Figs. 6 and 7 illustrate a modification; and

Figs. 8 and 9 depict another modification.

The staples 1 are placed in the jaw 2 having a plurality of teeth 3. The end of the belt 4 is then passed between the upper points 5 and the lower points 6 of the staples 1, and between the wedge 7 and the keeper 8. The wedge 7 is driven. home. The pin 9 is inserted as soon as the staples 1 are inserted in the jaw 2. 7

With the parts in the position shown in Fig. 3, the ordinary hammer 10 is used and clenches the staples 1 into the shape shown in Figs. 5 and 1. 0

After this, a twill of twisted rawhide or the like (not shown in the drawings) is Specification of Letters Patent.

passed through openings 11 in all the staples -1 causing them to meet together and overlap from opposite pieces of belting brought to- "gether end to end. a

The teeth 8 are preferably formed by saw cuts alongthe bend of a U-shaped plate 12 and a'plate 14 is so disposed between the arms of the U-shaped plate 12 as to provide or anvil 15 by rivets 16 or. other suitable means. 1

The jaw .teeth 31 hold the staples 1 quite in Figs. 6 to 9 is to afford a brace for them so that they will be more steadily held. Such brace or steadyingdevice takes the form in Figs. 8 and 9 of the wedge 16, which, when driven home as shown in Fig. 8, holds the staples 1 very firmly and steadily while the same are being hammered by hammer 10.

The said brace'or steadying device in Figs. 6 and 7 is in the form of a thumbnut 17 which applies pressure to plate 12 and causes the same to press the lower part of the staples against the plate or anvil 15.

In Figs. 6 and 7 the anvil or plate 15 is shown as provided with an integral upturned front portion 18 which cooperates with a clamp 19 pivoted at 20 on a pin 21 that runs through a bend of the anvil15 to hold the belt a, thereby preventing dis placement of the same during the stapling operation. In use, belt 4 will be'fed be tween the upturned portion 18 and the strap 22 of clamp 19. Plate 12, in Figs. 6 and 7 especially, is more or less resilient and therefore responds to the action of the thurnbscrew 17, thereby causing the teeth 3 to press upon the staples 1, holding the same steady.

The thumbscrew 17 consists of the winged nut 28, the screw 24, and the clamping member 25, the latter being adapted to press on rod 26 that extends from one side to the other of the clamp 19. Turning nut 23 down on screw 24 causes clamping member 25' to press on rod 26 and thus to clamp the belt between clamp 19 and the upturn 18.

It is to be understood that the constructions depicted in Figs. 6 and 7 and 8 and 9 can be united in one, that is to say, wedge 16 may be placed in the device illustrated in Figs. 6 and 7.

steadily for the impact of the hammer 10, but the object of the modifications depicted Having thus described this invention, We hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims.

e claim:

1. A belt lacing device comprising a plate having staple receiving means, a staple retaining pin passed through said plate, a clamping device engaged with said plate ,to hold the staple retaining pin in position a Urshaped belt holding member having a cross rod engaged by said clamping device, and tensioning means for said clamping device.

2. A belt lacing device comprising a plate having staple receiving means, a staple retaining pin passed through said plate, a clamping device engaged with said plate to hold the staple retaining pin in position,.a U-shaped belt holding member having a cross rod engaged by said clamping device, tensioning means for said clamping device, and an anvil supporting said plate.

8. In a belt lacing device, the combination signatures.

of a U-plate having teeth at its bend, and arranged to hold staples between the teeth, a removable pin securing the staples within the U-plate, a member'arranged to'advance along an inclined plane to clamp said staples against displacement, means to hold the belt tion, a belt holding means to securely hold belt against displacement and in operative relation to the staples, said belt holding means operated by said screw clamp, and an anvil on which the staples are to be clenched in said belt. i

In testimony whereof we hereunto affix our isin on M. JACOBS. VVlW. CRAMER.
