Application filed October 1, 1921. Serial No. 504,751.

To all whom it may concern:

Be it known that I, lVIATHEW F. BrnnsnoRr, a citizen of the United States,.residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Machines for Cutting Pockets in Garments, of whichthe following is a specification. I i

This invention relates to a machine for cutting pockets in garments and is particu: larly adapted for cutting pocketsin several pieces of cloth at one timesuch as isiusually done in the manufacture of large quantities oishirts or other such garments.

It is theobject of this invention to provide a simple and rapid means by which theseveral pieces of cloth which are usually stacked one upon the other, can be easily out. i I I Another object is toprovide a cutter that will partially rotate and will thereby, easily cut the cloth without anyexcess pressure of the cutter upon the goods and the cutter is oscillated so as not to pull the clothin one direction.

Other objects and advantages will be seen and the invention readily understood from the following description ofthe accompanying drawings in which:

Fig. 1 is a side elevation of the device-, a side plate of the cutter support being removed to show the cutter actuatingmeans.

Fig. 2 is a partial end elevation taken on line 2-2 of Fig. 1. I

The device as shown comprises substan tially a base 1 having depending legs 2 and 3, the leg 2 having an ordinary U-c1amp4 so as. to clamp the device firmly upon a table 5 or other suitable object. Projecting .upwardly from the leg 3 is a hollow box structure supporting standardfi within which is mounted a vertical screw threaded shaft. 7 suitably journaled at its upper and lower end in bearing supporting members 8; and-9, the lower end of the shaft carrying a bevel gear 10 having engagement with a second gear 11 suitably journaled in the lowerportion of the leg 3 and thesegearsare suitably actuated by the gear train 12, the final gear of which is driven by a shaft 13 suitably journaled in both of the legs and having crank arm 15 fastened to the outer end so that when the same is rotated, the shaft 7 will be rotated also and will cause a sup.- porting arm 16 to be raised and lowered 18 havingvertical slots 19 tormed on-each side of the head and adapted to engage the inwardly projecting portions 20 of the front side of the support, a slotbeingtormed between theends 20. It will thus be seen that the arm 16 will be prevented from having rotatable movement'when the. screw is rotated. f

The support arm 16. which projects forwardly from. the head 18 comprises two channel members21, the backs of which are spaced apart so asto form a guide slot 22. Slidably carried u'ponthe arm 16 is the driving motor 23 mountedupon a base v2 1 which has a depending guide portion 25 slidably received within the slot 22v and projecting downwardly from this guide portion is. the cutter support 26. terminatingin a curved portion 27. t

l/Vhen cuttingseveral pieces of cloth,it is necessary that the cutter and support :be very thin so that it will easily enter the cloth and to provide thisnecessary construction the cutter support is shown as two thin plates 27 bolted at their upper endsto a portion 28. depending from the guide portion '25 as by bolts29 or, any other suitable construction. Rotatably mounted upon the lower end. of the cutter supportzisthe cutter here shown as suitably journaled in rollerbearing's 31 mounted, upon a shaft Means for oscillating the cutter by the motor '28. comprises substantially a crank pin 33 formed on oneje'nd of theumoto'r ably journaled thereon at one end andconnected as at 35 t0 aguide rod 36 slidably. journaled in the forward endoi' the base a very. thin, so asto, make the whole cutter support. relatively narrow.v One of the plates 27 is shownas cut away at .40 to receive the arm 37, at alto receive the arms 39. and at 42 to receive the cutter .an'dI'the other plate will fitagainst the projecting shattand having aconnecting rod 341 suitgortions' formed by the portions cut away. y such a means a very rigid construction is obtained. It will thus be seen'that if the motor is operated thecutter 30 will oscillate so as to easily cut the cloth.

To hold the cloth while it is being cut, a clamp member 43 is shown as vertically slidably mounted upon clamping supports 44 and theclamping member can have any suitable clamping means such as an. eccentric actuated by a lever arm 45 and adapted to engage the supports 44. A. longitudinal slot 46 is formed in the base so as to allow the cutter to pass through the same.

Suitable adjusting means are provided so as'to allow the cutter to be moved forward ly and backwardly so that the cloth can be cut at any desired position within range of the device. Such a construction embodies a rack 47 mounted upon the upper side of the lower flange of one of the channel members 21 and depending from the base of the motor on the outside of the channel members are bearing supports 48 suitably cross connected beneath the channel members. Journaled in one of the supports 48 is a shaft 49 carrying a pinion 50 adapted to engage the rack 47 and having any suitable actuating means such as a knob fastened on the shaft 49 and it will thus be seen that as the pinion is rotated, the cutter and motor will be shifted longitudinally and to clamp the same in any desired position, suitable clamping means such as an eccentric51 is carried by a shaft journaled in the opposite supporting arm 48 and has an actuating lever 52. The clamping means for the member 43 is similar to that just described.

In the operation it will thus be seen that the general construction will allow the cutter to be shifted longitudinally and also vertically which latter adjustment actuated by the crank arm 15, allows the cutter'to cut down through the cloth.

Various changes may be made in the details of construction by those skilled in the art, without departing from the spirit of my invention as set forth in the ap pended claims.

Nhat is claimed is:

1. In a machine for cutting pockets or the like in garments comprising a base to support said garments or the material for the same, a cutter, and means for independently moving said cutter vertically toward and away from the base and horizontally across the base.

2.
