SPECIFICATION formingpart of Letters Patent No. 761,585, dated May 31, 1904.

' application filed' May 6, 1903. Serial'No. 155,840l. (No model.)*

To all whom it may conceive.-

ofZurich, Republic of Switzerlandghvhose post-office address is No. Ienatschstra'sse, Zurich,) have invented certain new and useful Improvements in Machines for Making Shavings from Steel Wires or Steel Bands; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying drawings, and to figures of reference marked thereof the friction owing to the pressure of the wire or band on. the disk or ring and passed over a series of cutters, whereby a series of pressure-rollers presses constantly the wire or band to the periphery of the disk or ring.

In the annexed drawings, Figure 1 is a vertical section of the machine. Fig. 2 is a diagram of the same. Fig. 3 is a detailed View, and Fig. 4 is a section on the line 0am in Fig. 3. Fig. 5 is a detail view of the toolholder.

1 is a circular disk fixed to a vertical shaft 2 and capable of being driven by means of a circular rack 3, a pinion 1, .shaft 5, bevelwheels 6 7, shaft 8, and pulley 9. The periphery of the disk 1 is slightly grooved, and this groove receives'the wire 10 bent in shape of a loop around the disk 1 and to be treated. Each of the pressure-rollers 11 is carried by a fork 12, the stem 13 of which is movably fitted in a boss 1 1 of a standard 15, screwed on the frame 16 of the machine. A spring 17 placed in theboss 14;, presses constantly Be it known thatI, HENRI GRAF, a'citizen of Switzerland, residing inZurich,'in the-canton.

on the fork 12, so that the roller 11 is firmly pressed against'the periphery of the disk'l and uponthe wire to be treated.

The pressure-roller 11 is fixed on a spindle 18 with head 19 having two grooves 20 21 intersecting each other at right angles. The lower end of a link 22 engages the groove 20, while'two plugs 23, fitted on a cross-pin 24 of the link, engage the other groove 21. A similar joint connection exists between the upper end of the link 22 and a spindle 25, journaled in the standard and provided with a spur-gear 26. The disk 1 carries support 27, to which is bolted a ring 28, having a spur-gear 29 on its periphery, which gears with the teeth of the spur-gear 26.

The different standards 15 carry a grooved ring 30, to which the tool-holders 31 are fixed by the bolts 32. These tool-holders may be of any known and suitable construction and form no part of the invention. By means of these tool -holders the cutters 33 may be brought into the correct position relative to the wire or band to be treated.

When the disk 1 rotates, the wire is taken from a reel placed beside the machine along with the disk. This movement is owing to the pressure of the rollers 11 against the wire and to the impulsive rotation of the said rollers. This pressure of the rollers produces 'a friction between the disk 1 and the wire, which friction, together with the driving power of the pressure-rollers, is greater than the working resistance produced by the cutters. When the wire has passed all cutters, the remaining part of the wire is again wound on another reel placed on the other side of the machine, these reels not being shown on the drawings. The joint connection between the parts 18, 22, and 25 permits a slight radial movement of the pressure-rollers,according to the different thicknesses of the wire or band, while. the spindles 25, with the spurv gears 26, remain stationary.

The number of the cutters and ofthe pressure rollers may greatly vary. Different kinds of shavings'may be made, if desired. 7

Instead of the disk 1 a rotating ring may be used Without altering the nature of the invention.

What I claim is- 1. In a machine for making shavings from steel Wires or steel bands, the combination with a rotatable disk or ring adapted to receive on its periphery the loop of a steel Wire or steel band, of a series of cutters placed stationary around the said disk or ring and adapted to cut shavings from the loop of the Wire or band encircling the disk or ring and of pressure rollers also placed stationary around the said disk or ring and fitted to press the-Wire or band against the disk or ring substantially as set forth.

2. In a machine for making shavings from steel Wires or steel bands, the combination With a rotatable disk or ring adapted to receive on its periphery the loop of a steel wire or steel band, of a series of cutters placed stationary around the said disk or ring and adapted to cut shavings from the loop of the Wire or band encircling the disk or ring, of pressure-rollers also placed stationary around 5 the said disk or ring and fitted to press the Wire or band against the disk or ring and of means for imparting a rotary movement to the rollers from the disk or ring, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of April, 1903.

HENRI GRAF.
