MACH IN E FO R-CREASING LEATHER.
SPECIFICATION forming part of Letters Patent No. 746,150, dated December 8, 1903.
Application filed March 18, 1903. Serial No. 147,656. (No model.) I
To aZZ whom it may concern: 7
Be it known that we, HENRY L. PLUMMER, J r., and CHARLES D. WITH-ERsPOON, citizens of the United States, residing at Peter sburg, in the county of Dinwiddie and State of Virginia, have invented certain new and use-- ful Improvements in Machines for Oreasing Leather, of which the following is a specification.
This machine is design ed to score and burn a-crease in the surface of leather, such as leather straps and bindings.
The machine comprises means for supporting and feeding forward the leather strap and a revolving creaser which is run at high speed, so that it not only forms the indentation, but heats the leather along the depressedliine by friction to a temperature which discolors the leather, producing a brown or black crease.
The invention will be more readily understood by reference to the accompanying drawings, in which Figure 1 is a transverse vertical section of the upper part of the machine, taken on line I I of Fig. 2. Fig. 2 is a vertical longitudinal section taken on line II II of Fig. 1, and Fig. 3 is a side elevation of the machine.
The machine comprises a frame 1, of wood or metal, supporting a feed-table 2. Upon this table are secured a number of parallel guide-strips 3, arranged in pairs. Beneath the table is a transverse horizontal feed-roll 4.,
carried by a shaft 5, which is journaled-in boxes 6. Each of these boxes is vertically movable in a hanger 7, secured to the under face of the table, and is supported upon a driving-pulley 15.

Each of the creasers (shown as five in number) is a disk 19, having a pair of peripheral ribs, 20, one near each edge of the disk; Between each pair of creasing-disks is a spacing-collar 21. The disks and collars are bored to fit smoothly upon the shaft and are clamped against a shoulder 22 at one end of the shaft by a nut 23, running on a thread 24, near the other end of the shaft.
In using the machine the leather strap is fed forward between the guides 3 and entered betweenthe feed-roll and one of the creasing-disks." The slowlyrevolving roll,
bearing against the under surface of the strap,
thus feeds it forward and out the other end Meanwhile the ribs on the come in contact with it, but by reason of the great friction occasioned bythe fact that they slip upon the leather as it is moved slowly beneath them by the feed-roll discolor the depressed line and may be said to burn it to a deep brown-or black. It will be evident that the speed of the feed-roll rather than that of the creasing disk determines the rate of feed of the strap, since it bears against the strap entirely across its lower surface, while signed to crease a strap, it is obvious that the guides may be omitted and a crease burned in a piece of leather of any width. By using a creaser of narrow diameter the leather may be shifted as it is passed through the machine to produce a curved or ornamental line. While the feed-roll shown is a convenient means for carrying the leather forward under the creasers, the leather may be fed by hand or by well-known mechanism.
NVe claim--- 1. A machine for creasingleather, comprising means for slowly feeding forward the leather, a revoluble creaser, means for driving the creaser at a sufficient speed to score and burn a depressed line in the leather, and guides for retaining the leather beneath the creaser as it is fed forward, as set forth.
2. A machine for creasing leather, comprising a feed-roll, means for driving the roll at a comparatively low speed, a revoluble creaser, means for driving the creaser at a sufficient speed to score and burn a depressed line in the leather, and guides for retaining the leather beneath the creaser as it is fed forward, as set forth.
3. A machine forcreasing leather, comprising a feed-roll journaled in yielding bearings at each end, means for driving the feed-roll at a comparatively low speed, a revoluble creaser, means for driving the creaser at a high speed, and guides for retaining the leather beneath the creaser as it is fed forward, as set forth.
4. A machine for creasing leather, comprising means for slowly feeding forward the leather, a revoluble creaser, and means for driving the creaser at a high speed and in the opposite direction to the feed of the leather, as set forth.
5. A machine for creasing leather, comprising a feed-roll, means for driving the roll at a comparatively low speed, a revoluble creaser, and means for driving the creaser at a high speed and in the opposite direction to the feed of the leather, as set forth.
6. A machine for creasing leather, com prising a feed-table carrying guides, a feed-roll projecting through the table, means for driving the feed-r011 at a comparatively low speed, a creasing-disk having one or more ribs running between said guides, and means for driving the creasing-disk at a high speed, as set forth.
7. A machine for creasing leather, comprising a feed-tab e carrying guides, a feed-roll journaled in yielding bearings and projecting through the table, means for driving the feed roll at a comparatively low speed, a creasing-disk having one or more rihs running between said guides, and means fordriving the creasing-disk at a high speed, as set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
