Title: Improvements in Machines for Fleshing Hides or Skins.
Inventor: WILSON EDWARD
Filed: 1900-11-14
Granted: 1901-09-28
Abstract: 20,533. Wilson, E. Nov. 14. Drawings to Specification. Sharpening.-In a machine for fleshing hides or skins, the knives are ground by means of an emery wheel and a leather wheel mounted on the machine. The knives are in the form of spring blades, and, in order that their forward or advancing edges may be cut deeper than the rearward edges, the stirrup-shaped frames which surround and guide the blades are so shaped as to tilt the blades slightly when they are in the grinding position. The same effect can be obtained by forming the underside of the knife with a concave surface. A bar or plate may be arranged to bear upon the knives after they pass the sharpener, so as to remove any burr or wire edge that may have formed. The Provisional Specification describes a means for accurately adjusting the position of the grinding-wheels, comprising a hand-wheel, worm, toothed sector, and adjustable stops.

Granted: 1902-07-03
Abstract: 13,779. Boult, A. J., [United Shoe Machinery Co.]. July 6. Eyeleting; lacing-fastenings.-Relates to machines for setting eyelets, rivets, lacing hooks or studs, and similar articles, and more particularly to eyeleting &c. machines in which a punch is used to form a hole in the work to receive the eyelet &c. The punch is used to feed the work to the setting- dies, the upper of which is formed separate from the punch, and displaced by it during feeding, and returned to setting position, and so that it protects the cutting-edge of the punch, some other part of which then forms an abutment for the die. An eyeleting-machine is shown in side elevation in Fig, 1. A lever 8 is pivoted on a rod 9, which is mounted to turn in the upper portion of the framing, and provided at the lower end with a nut 10 and spring 11. The rear end of the lever 8 extends through a slotted yoke 12, carried on a vertically-reciprocated rod 13, a cam roll on which engages a cam-groove in the rear face of a disc 15 on the shaft 2. The lever 8 is moved laterally by a lever 17, which is provided at the lower end with a cam roll engaging a cam-groove in the front face of the disc 15, and bears at the upper end against a screw 18 on the lever 8, and is retained by a spring 20. Another vertically-reciprocated rod 4 carries the lower setting-die 5. The mechanism so far described is of known type. The punch is mounted on the lever 8, and the cam-groove for the rod 13 is shaped to give the punch a downward punching- movement, followed by a slight upward movement to clear the work-support 27, but not the work, which is then fed over the die 5 by lateral movement of the lever 8 and punch. The upper setting- die 23 is preferably mounted as shown in Fig. 5 The die is divided longitudinally, each part being secured to, or formed on, a lever 24 pivoted on a block 26, which is supported above the worksupport 27 by means of a sleeve 28. A spring 30 connects the levers 24, which are limited by stops 24<a>, and bevelled at the ends to form a notch for the punch 22, which first separates the levers 24, and then rises from the lower to the upper position indicated in dotted lines, so that the upper surfaces of the levers 24 rest against a shoulder of the punch. An adjustable work-guide is secured on the support 27, and a presser-foot 32, Fig. 1, is secured to a sliding rod 33, and normally held against the work by means of a spring 34 and adjustable collar 35. The lower end of the rod 33 rests on one arm of a three-armed lever 36, another arm of which is connected to a treadle, and the other arm operated automatically by a roll 39 on a block 38 on the shaft 2. The modiSed form of upper setting-die shown in Fig. 9 is undivided, and is carried at the free end of an arm 29 projecting over the work-support 26 from a sleeve loosely mounted on a fixed rod 31, a coiled spring being secured to the sleeve and to a collar adjustable on the rod. The reduced portion of the punch is received in a slot 37 in the arm 29.
