CHARLES H. CORY, OF SAN JOS, CALIFORNIA.

LEATHER-GREASER.

sPEcIEIeATIoN forming part of Letters Patent No. 260,847, dated July 11, 1882.

Application filed May 52, 1882. (No model.)

To all 'whom it may concern:

Be it known that I, CHARLES H. GOREY, of San Jps, county of Santa Clara, State of California',` have invented an Improved Leather- Greaser; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improved tool for creasing leather for harness or other purposes;

von its surface.

j a more complete explanation of my invention,

Figure lis a perspective view of my improved machine. Fig. 2isaside elevation ofthe creas ing-roller.

In the ordinary construction of machines for creasing and ornamenting tugs and straps for harness and other leather work two anged rollers are employed having the creasingridges formed upon their peripheries. These rollers are geared to run together so that the ridges will exactly correspond upon each side, and the anges upon their sides guide the leather as it passes through. In its progress between these rollers, however, the leather becomes stretched or elongated, so thatthe ridges would not follow the saine marks if the leather were again put through the rollers. Colisequently the creasing must be completed at one operation, and if it is imperfect in any partv it can only be remedied by hand. My machine is designed to hold the leather so thata single creasing-roller without flan ges may be passed over it any number of times and the ridges upon the rollers follow the indentations exactly.

A is a table or bed, having a strip, B, fixed at or near one side and extendinglengthwise.

C is a movable strip, havingV slotted adjusting-plates D projecting at right angles from one side, and provided with bolts E, passing through the slots, so as to hold the strip (l in any position with relation to the strip B. Between these strips the leather strap F is laid and held in place by securing the movable strip closely again stit, and the friction of these sides and the bottom upon which it lies prevents any elongation or stretching when the creasing tool or roller passes over it.

The roller G is made without iianges upon its ends, and has a slightly-concave face, upon which the ridges H are raised. These ridges are of a wavy or other form which will imprint upon the leather the desired lines or creases. The axle I of the roller has its ends bearing in .the sides of a frame, J, which extend down upon each side ofthe bed or table A, being united at the top and bottom by crossbars, as shown. The sides ot' theframe-may have slots K extending outward from the bearings ot' the axle, so that the latter may be removed at any time. 1 A weight may be sus pended from the lower cross-bar to cause the roller to press upon the leather. When the leather has been laid upon the bed and the side bars set up against it the roller lits between these side bars and is guided by them. The frame J is then pushed along so that the roller traverses the leather as far as the creasing is to extend, and, as the leather cannot elongate, itis manifest that the roller may be moved back and forward over until the creasing is as deep as may be desired, and that it will always follow the same lines.

Another advantage in my device is that the lilies of creasing may commence and end at points within thelength of the strap; but when double rollers are used between which the straps must pass one end of the leather is entered between them and it is creased the entire length, and the creases at the ends must then be worked out before the strap is made up into a -tng or otherwise tiuished.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is r In a leather-creasingapparatus, the bed A, with its adjustable holdingguides B O,in conlbination with the frame J and the creasing'- roller G, having its axle journaled in the sides of the frame, said roller adapted to travel over the upper surface of the bed between the guides, substantially as herein described.

In witness whereof I heretoV set my hand.

CHARLES HARRIES UOREY.
