LEATHER-WORKING- TOOL.

Application filed Decemser 20, 1927. Serial No. 241,360.

T he present invention relates to improve- ,1 ments in tools and has reference more particularly to an implement that is adapted to be used in cutting strips of leather of various widths in a simple and efiicient manner. V j 7 Another important object of the invention is to provide a tool of the above mentioned character wherein means is provided for creasing the strip of leather, additional means being associated with the tool whereby holes may be punched in the-strip.

A further object of the invention is to provide a tool of the above mentioned character wherein the blade carrying gage bar may be adjusted to facilitate the cutting of strips of leather of any-desired width, means being provided ior securing the slidable gage bar in its adjusted position.

A still furtherobject is to provide a tool of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages'of the invention will become apparent from the following description when taken in connection with the accompanying drawing.

In the accompanying drawing forming a part of this specification, wherein'like reference characters indicate like parts:

Figure 1 isa top plan view of the leather working tool embodying my invention.

Figure 2 is an edge elevation, and Figure 3 is a side elevationot the tool. In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally my improved leather working tool, the same comprising a substantially rectangular shaped metallic body 2 that is solid and that has formed at its inner end, a

downwardly curved handle The solid body 2 is formed with a transverse slot that extends through the opposite sides thereof, and the purpose of this slot will be presently described. I

A substantially U-shaped yoke member denoted by the numeral 4 and formed from a single strip of flat metal has its crown portion spaced from the outer end of the solid body 2, the arms 5 of this yokemember being disposed against the respective sides of the body as clearly illustrated in Figure 1. The arms 5 are formed with the elongated registering slots that communicate with the slot t torm ed in the body 2. A laterally extending linger 6 is formed onthe upper edge of the innermost arm at the freeend thereof,

and the purpose of this finger or ear will be hereinafter more fully explained.

A gauge bar 7 is slidablethrough the slot formed in the solid bar 2 and also through the registering slotsformed in the intermediate portions oi the arms 5 of the yoke, member 4, and the upper face of this gauge bar is provided. with a conventional scale 8 as shown very clearly in Figure. 1.

A vertically disposed cutting blade 9- is formed at its lower end with a laterally 'ex-,

tending attaching flange'lOcthat vis adapted to be secured to the inner end of the bar 7 in any appropriate manner such as is shown at 11 with reference more particularly to Figure 2 and the cutting edge of thebladefaces the handle portion 3 and is disposed at extreme inner end of the bar.

For the purpose of locking the slidable bar, it:

7 in a fixed position so that the cutting blade 9 may be held in proper spaced relation with respect to the inner side of the body 2, I provide a block 12 that is disposed-between the outer end of the body 2 and the crown pore I tion of the yoke A and a thumb screw 13 ex: tends through a suitable opening. in the crown portion of the yoke and is threaded through an. opening formed in the center of the block 12, the inner end of the thumb screw.

engaging the outer end of the body 2 and manifestly by turning the thumb screw in one direction, said block 12 willcooperate with the yoke to effect a sliding movement thereof in an outward direction so that the slotted arms 5 of theyoke will engage the rear edge of the guide bar and force the forward edge of the bar into engagement with the forward edge of the slot formed in the 7 body, and in this manner, the slidable bar will be locked in its adjusted position.

The outer end of the gage bar 7 is formed with a threaded opening to receive the externally threaded portion of a leather punch with a tool engaging head715.

A leather creaser 16 is carried by the lower end of the handle portion 3 for the purpose of creasing the strip of leather'in the'man- 14, said punch being formed at its upper end In use, the thumb screw 13 isloosened to r permit the free slidingmovementof the gage bar 7 with respect to the solid body 2 whereby the blade 9 may be moved laterally with respect to the body in order to permit the proper width of the strip that is to be cut from the large piece of leather to be accurately measured and in this manner the scale 8 provides a meansto readily ascertain the distance between the cutting edge ofthe blade 9 andthe innermost arm 5 of the yoke d. After .the blade has been properly adjusted or spaced with respect to the body 2, the set screw 13' is tightened whereby to lock the gage bar inits adjusted position against slidll'l'gIIlOVBIIlGIlt; The handle 3 is then grasped w1th=one'of the fingers oi? the-operator being in=engagementwith the finger grip 1'? and the toolis-then' drawn toward theperson using thesame, one edge of the leather being disposed against the inner arm 5 of the yoke 4 and the laterally extending finger or ear 6 will=be disposed=above the upper face of the j leather to insure the proper positioning of the same. The cutting edge of the blade will therrcut through the leather in this mannera strip' of any desired width may be cut from alarge piece of leather. The'creaser 16 may then be usedfor creasing the strip along its edge portion and the punch let is then utilized for the purpose of formingone or more holes'in' the strip. 7

It will thusbe seen from the foregoing description, that I have provided a leather working toolwhich will at all times be positive and'eificient in its operation, and due'to its'simplicity the blade carrying bar can be readily andeasil yadjusted to cut strips of leather of various widths.

Wliile'I have shown the preferredembodimen-t ofmy invention, it is tobe understood that various changes in the size, shape and arrangement of parts may be resorted to V 7 without departing from the spirit of the in-' ventionand"the scope ofthe appended claims.

iHa'ving' thus described the invention, what 1. Ina toolfot the class described, a solid body formed with a'transverse through slot, a

rearwardly extending handle at one end'of through which the bar is slidable, a block disposed between the outer end of the body and the crown port-ion or the yoke, a screw extending through the crown portion of the yoke and the block and adapted to engage the outer end of the body for the forcing of the.

yoke outwardly tolockthe bar against slidarm of the yoke'a-t the free end thereof-to prevent upward movement of the work while the tool is in use. l

2. In a leather cutting tool of the class described, a solid body, a downwardly curved handle formed on the rear end of the body, said body'being provided with a transverse through slot, a substantially U-shaped yoke, the crown portion'thereof being spaced from the outer en d of the body, the arms of the yoke.

being disposed against the respective sides of the body and formed with slots that register with the slot in the body, a fiat gage bar slidable through the communicating slots, a vertically disposed cutting blade carried by one end of the'gage bar, a block arranged within the yokebetween the outer end of the body and the crown portionof the yoke, a screw extending through the crown portion of the yoke and the block and adapted'to engage the outer end of the body for moving the yoke outwardly to lock the bar against sliding movement in any adjusted position,

and a laterally eXtending'ear formed on the upper edge of the innermost arm of the yoke at the free end'thereot to prevent upward movementof the of the same.

In testimony whereof I affix my signature.
