L Y n 'Unirse STATES JOSEPH E. MERRITT, OF WINN, MAINE.

MACHINE FOR ROLLING UP LEATHER.

Specification forming part of Letters Patent No. 52.87B dated February 27, i866.

. To all whom t may conoci n:

Beit known that I, JOSEPH E. MERRITT, of Winn, in the county of Penobscot and State of Maine, have invented a new and useful Improvenlentin Machines forRolling Up Leather; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in which- Figure lis a side view, partly in section through the line w x, Fig. 2, and Fig. 2 is a top or plan view of my machine.

Similar letters of reference indicate like parts.

My invention has for its object the furnishing a machine for rolling up leather in rolls for transportation 3 and it consists of a lnachine constructed as hereinafter more fully described.

The frame A restsV upon a foundation or feet, B. This foundation B should be of sufl- Cient, height for conveniently. placing the leather upon the belts. rThe frame Ais arched in the central part, as shown in Fig. l, so as to allow easy and convenient access to the belts for placing the leather thereon without weakening the strength of the frame. The rear ends of the side pieces ofthe frame A are slotted, as seen at G, Fig. l. In these' slots work or slide the bearings D of the roller E.

To the outer sides ofthe blocks or bearings D are attached pawls F, which take hold of the racks G and prevent the blocks D and roller E from being forced back by the springs H when it has been drawn forward, as hereinafter described. The springs H are placed in the slots O, one end of said springs resting against the forward end of the ,slots and the other end against the forward sides of the blocks D, as shown in Fig. 1.

E is a roller extending across the rear end of the machine from one side to the other and working in the bearings D.

In the forward ends of the side pieces ofthe frame Aare formed slots, as seen at I, Fig. 1. These slots form the bearings in which the roller J revolves.

Upon the upper sides or edges of the side pieces of the frame A are formed vertical slots K, in which slide the bearings of the roller L. To these blocks or bearings are atltached racks M, into the teeth of which are geared the pinions of the pinion-wheels Nattached to the shaft O. This shaft is supported by and revolves in bearings in arms attached to the standards P attached to the frame A, as seen in Fig. l. These standards P also support the racks M and hold them in place against the pinions of the wheels N.

Upon the end of the shaft O is placed a ratchet-wheel, It, the -pawl S of which is attached to the standard P. To the end ofthe shaft O is attached a crank, T, by means of which the roller L may be raised or lowered as desired. U are bands or belts passing around the rollers E and J and their ends joined, as shown in Figs. l and 2, the pin holding the ends of each belt together being removable at pleasure. In the cross-piece A of the frame Aare placed pins, as seen in Figs. l and 2, to serve as guides in keeping the belts U in proper position upon the rollers E and J. Motion iscOminunicated to the machine by means ofthe crank V attached to the projecting axle of the roller E.

The machine is prepared for operation by raising the pawls F from the racks G. This allows the springs H to force back the roller E, which tightens the belts U. The belts U are further tightened by lowering the roller L upon the belts U, as shown in Fig. l. This not only tightens the belts, but also gives a downward direction to the end of the side of leather as it comes over the roller J, so that it is wound around said roller, as shown in Fig. l. The leather WV is laid upon the lower parts of the belts U, as shown; then by turning the crank V the leather isiI drawn forward and wound upon the roller J.

When the roll has been made of the desired size it is tied up by passing the cord around the rol-l and roller. The pawls F are then lowered into the racks G and the roller L raised, which slackens the bolts Ufso much that the pins which hold the bel/tsU together can be withdrawn andthe beltsreinoved from the roller J. The roller and roll of leather are then removed from the slots I and the roll of leather slipped from the roller. The roller is then replaced, the belts connected, the pawls F raised from the racks G, and the roller L lowered. The machine is then ready to prepare another roll.
