parts in all the figures.

' The machine is mounted onsubstantial On the top of the frame which is repeatedly interframework a @421 and rollers; may be suitably mounted. The

Ffront portion 6 of the table supports the hide when the operationbegins. A pair of feedrollers c c are provided here, whicl'i draw the hide in and movejsame forward. All hides are of irregularshape. Therefore the side ends .mustbe cut oil when straps are to be made.

For this purpose'two cutting-knives d d are mounted; right behind the feed-rollers c 0.

These knives are secured to a hide-guiding device c -e,

whichis. mounted on two metal rods 0 e-.and adjustable thereon according permanently fastened to the lower The two rods are side portionof'the-frame a2 Nearthc rear end of to the width of the-hides.

the adjustable guide e' e there is another pair of feed-rollers f f.' Then follows a small guidmg-roller g, which keeps the hide down on the table when it is out. It is rotated by the movin hide. Adjoining this guidin roller there is a device for cuttin thehide into straps. It consists of a smal frame it and a number of blocks having each permanently secured thereto a knife i, which stands verticall y up and slightly forward Small iron blocks are inserted between the knives and both are held together by tightening-screws located on the outside of the frame. The small blocks between the knifeblocks are of different width, whereby this device is made adjustable and adapted for cutting straps of'various widths. A guidingroller j is mounted in the frame near the strap-cutting device. As shown in detail in Fig. 5, it consists of an iron rod 7' and a tube j which carries thin guiding-disks 7', ar ranged at such distance as is required for the vxl lidth of the straps which pass between t em.

justable. A third pair of feed-rollers k is mounted 'in the frame to move the straps forward. All three pairs'of feed-rollers are vertically adjustable, so as to suit the thickness of the leather. This is done by raising the top roller slightly, as indicated, on the set of re lerscc. Theside parts of theframeahave each a long slot f, in which three other guiding-rollers j j 1' are located. These are of the same construction as the roller shown in detail in Fig. 5. All the guiding rollers are turned by the moving leather straps and keep same down on the table. The straps when'passing these rollers come in contact with the tube 9' on the table. The part, 7' is the permanent part of these rollers, while the tubes with the disks may be exchanged for other tubes which have the disk'sat diflerent' distance, more or less of sired width of the straps.

Near the rear end of the table b there is a pair of creasing-rollers Z Z, of which the upper I one is exchangeable, while the lower one is permanently mounted and smooth. The creasing-roller Z consists ofa shaft Z and a toward the hide.

This roller is mounted in two slots d7" in the frame a,. so that it is horizontally a while the guiding-disks slide them,.according to the detube Z on which the creasing appliances Z are provided. For straps of various widths fgdiflerent toilets are used,.;which have each the creasing appliances at a distance corre- The frame a carries parts extend throughout the entire length of in a small frame m the machine. A third frame a is located on the middle portion .of the frame a. These frames carry a device for punchin the small round holes into the stra s and t ee other devices, one for cutting o the acute angular front ends, and a second one for cutting ed the rear ends of the straps, and a third one for punching the long holes one in each strap near the rear end of same. The first device is operated alone, while the three other ones are operated simultaneously. The device for punching the round holes is located between the feed-rollers 7c and the guidingrollerjf. The punches roper,m, are permanently secured in small locks m, which rest Small blocks m of different width are placed between the punches. The punch-supports m are held firmly together by an angle-iron m. A pin m passes through the angle-iron. Each of its ends passes through a slot m in the side of the frame a and enters a cam 71. on either side of the machine. These cams are on a shaft 0. Each cam has a circular but eccentric recess n, in

which one end of the pin m is located. When the cams turn, the pin m is moved up and down in the eccentric recess, and when the cam is down then the round holes are punched. During one revolution of the cams the punches descend once, and for a number of holes in each strap a corr'es onding number of revolutions by the cams as -to be made.

The elongated holes are made by a punch ing device. (Shown in detail in Fig. 4.) The punches roper, m have elongated cutting edges. his device is constructed like the device for punching round holes. The punches proper are secured in blocks m,- which are located in a'frame 'm and have blocks m between for the purpose of adjusting them for the straps of various width. These parts are held together sidewise by screws 8. There is an angle-iron m and a small latch m thereon, which retain the blocks in position. The angle-iron m has on each side an uprising bar 111. with a shoulder "m on each bar extending outwardlyintoa slot p in the frame 02*. Two slots 1) are in the to parts of the frame a one in each side, (see Fig. 2,) through which screws p pass down into the shoulders m Thus this device is supported by the frame (1 The device for cutting off the rear ends of, the straps is constructed like the device for punching the long holes. One broad l nife 4 1s secured in a frame g and an angle-iron g holds it down. -Two small latches g are loare secured on t i cated on the "hunt; The angle-iron has uprising bars q, and the device is supported on the frame a like the device punching the long holes. This cutting device is held on the frame a} by screws q.

The device for cutting off the acute angular front ends of the straps is located in the rear portion of the machine between the guiding-roller i and the creasing-rollers. The cutting-knives 1' are mounted on a frame 1 and held in position b a L .r r, suitably secured by screws 1. e uprising side bars 1 have shoulders 1' which pass through lateral slots t in the rearportion of the frame a There arealso two slots t in the frame a (see Fig. 2,) through which pass the screws 1* down into the shoulders F. It is seen that this device is also mounted on the frame a. The knives 1' are of acute angular form and permanently mounted. For straps of another width the lower part is exchan ed -for one which is provided with knives at t e corresponding distance from each other.

In the central top portion of the frame a 5 there is secured a pm or rod 11., which extends through openings in the sides of this frame and enters with one end on each side into a cam 12.

e, which is supported in bearings '0 These thereon are operated together. The game 7) are constructed like thecams n andih ave each an eccentric recess -in which one of the rod 1/. is located. These cams thereforework' like the earns '11-. As the three devices for punching the elongated holes and'cutting off the acuteangular front ends andthe-rear ends are all supported by the frame a, the same are simultaneously actuated when the cams rotate.

The machine is referably operated by power. Small mac 'nes, however, may be made which are operated by hand and foot. The ower is applied through thepower. pulley w, whi'c is on the main shaft w. This shaft carries a gear-wheel an and a sprocketwheel y. Both are loose on the shaft. Between these two wheels a clutch z is mounted on the main shaft. The tooth-wheel a gears with a tooth-wheel m on the lower roller 1' of These cams are mounted on a shaft e top of-the frame 0?. Thus the frame a and the three devi'ces' mogggggl the creasing device.

When the lever and clutch are released, then this device 'stops. As previous! stated, the sprocket-wheel y is loose on t emain 'shaft. When the advancing straps come wit their front ends nearthe device for cuttin off the frontends, the clutch z isoperated E l". The clutchz, which was so far 1n the gearwheel a: and kept there bya spring z, is drawn out. Hereby the feed mechanism is stopped because'the gear a: is also loose on the main shaft and the movement of the straps ceases. By pulling the lever-the clutch enters the sprocket-wheel y, andthe sprocket y is rotated, which is on the shaft '0 of the cams '0. These move the pin or rod u u and down during one revolution, and there y the frame a is moved up and down with the devices for cutting off the rear ends tfitd the acute angular front ends and the device for unchmg the elongated holes. These are t us operated simultaneously during one revolution of the cams v.' Now the lever l is released and the clutch enters the gear a: again, whereby the feed mechanism is again operated. The straps move again. They ass the creasing device and drop outof t e machine. As shown in the drawin in Figs. 1 and 3, the table b isprovided with rubber plates below the punclung and cuttin devices.
