FRANCOIS DURAND AND ONESIBHORE PEGQUERMOEBAR-IS, FRANCE, ASSIGNGIRS .110-` RICHARD E. RABEAU. i

MACHINE FOR CUTTING LEATHER INTO HOLLOW-WARE FORMS.

Specication of Letters Patent No. 7,424, dated June 11, 1850.

To all 'whom/@'15 may concern: Y

Be it known that we, FRANCOIS DURAND and ONESIPHORE PECQUEUR, of Paris, in the Republic of France, have invented fa certain new and useful Machine for Manufacturing Articles of Leather Without Seam or Cement, and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known and ofthe usual Inanner of making, modifying, and using the same, reference being had to the accompanying drawing, which forms a part thereof, in whichi Figure l is an elevation of the machine, Fig. 2 is a plan.

The same letters refer to like parts in both figures.

The machine which is the subject of the present description and claim is for the purpose of making shoes of all kinds, boot legs, cartridge boxes, hats, caps, hose, fire buckets, gloves, &c. and consists of an upper frame A supported by six posts or legs B and braces C connecting them. That part of the machine which holds the leather, and advances it to the knife to be cut consists of two rollersD D the lower D having longitudinal grooves cut in it parallel with the axle and supported in a swing H which is` joined to A so thatit can be raised or 10W- ered at pleasure; and the upper roller being grooved around its circumference asclearly shown in Figs. l and 2. This roller is sus-` pended in a frame F which is connected by.

its center with, and is borne by a lever E jointed by one end to the frame A and secured by the other to a catch E2. `These rollers, when in place, are geared together and are connected with the driving shaft J by means of a train of gearing consisting of an endless screw or worm wheel K on said shaft J that works into a gear wheel L on a upright shaft` on the upper end ofwhich,

above frame A there is a bevel wheel O gearing into another O on the end of the lower roller D above named.

On the upper end of the shaft J there is a plate of metal P which forms an adjustable eccentric; upon this plate are two guides l and 2 along which the crank pin 3 is made to slide radially by means of a screw 6 which Vturns in a bearing 9 affixed to the plate, and working into a nut on the slide 3 of the crank pin 3 to move it out or in, to or from the center or shaft J; two small ratchet wheels `of metal 7 may be aliixed to the end of the screw, which, as the plate P revolves,by being acted on by a dog 8 that is moved up and down by the circular n grooved ring lO strikes the ratchet which causes it to revolve (one of these causes the screw to turn one way, the other in a contrary direction, by striking the ratchet either above or below the axis).

The crankpin 3 is connected with the arm R to which the knife is attached by an adjustable connecting rod Q. The arm R is connected with the frame A by a fulcrum S on which it slides back and forth by means of a collarU so as toV give the knife a straight motion parallel with, and in front lof the rollers, which motion is insured by the connecting link V as in ordinary parallel motions. A guide W is affixed to the frame A to steady the knife in its vibration. "The dogs 8 can be thrown out or into contact with the ratchet wheel 7 to curtail or extend the vibrations ofthe knife, so as to form a margin of any shape that may be required, by lowering or raising the ring l0. This is done by its connection with a cam 12 by means of the shaft ll and its connections.

W'hen the leather is presented to this machine the rollers D D are adjusted to the knife Z so as to have the cut made in the center of the thickness, the parts are then put in motion by the driving pulley I or the shaft J which communicates with this motive power, and the rollers are made to revolve and draw in the leather, While the knife is put into motion and splits it to the breadth permitted by the adjustable crank. instead of the adjustable crank a pattern can be introduced to regulate the vibrating of the knife. i

Having thus fully described our improved machine, and its Inode of operation, What and the other circumferentially serve lirmly We claim therein as new, and desire to secure to hold the leather in any position.

by Letters Patent is- The combination of the vibrating knife 5 with the fluted rollers, constructed and operating substantially Vin the manner and for Witnesses: the purpose above fully set forth, one of L. RUOHET, Which rollers being uted longitudinally JOHN BARTLY.
