MACHINE FOR MAKING SHADE-FASTENERS.

SPECIFICATION forming part of Letters Patent No. 534,468, dated February 19,1895. Application filed February 27, 1894:. Renewed January 18,1895. Serial No. 535,415. (No model.)

To all whom it may concern..-

Be it known that I, ARTHUR W. CURRIER a citizen of the United States of America, re-

siding at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Machines for Making Shade-Fasteners, of which the following is a specification.

My invention is a machine for making wire fasteners or clamps for securing window shades to the rollers and the object of the invention is to provide a machine which will rapidly bend straight lengths of wire into clamps of the desired form.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is afront elevation of the machine embodying myinvention. Fig. 2 is a section on line 2-2, Fig. 1. Fig. 3 is a plan ,view, and Fig. 4 is a view of the fastener.

The machine consistsessentially of a shaft 4, journaledin suitable bearingsand operated from any desirable source of power in the usual or any preferred manner. This shaft is extended through an opening or bear ing 5 in a post 6, which post may be formed as shown of two

recessed sections

6 and 6 bolted together with the shaft 4 held between the abutting recesses. The post is formed of a width corresponding to the width of the fastener to be made, and is provided at its upper end with

inclined faces

6, 6 sloping downward toward each other and terminating in a slot 7 directly over the axis of the shaft 4. This slot is of the proper size to readily admit the length of Wire3 from which the fastener is to be made and when the wire has been fed to the slot, either by hand or from a suitable hopper, it rests upon the periphery of the shaft. The shaft carries upon each side of the post a block 8 secured rigidly thereto with its inner edge located in close proximity to the face of the post. The said inner edge is provided with a rabbet forming a groove 8 extending around the periphery of the shaft to the extent of the block. When the straight length of wire is inserted in the slot, the blocks being out of line therewith, the wire as before stated lies upon the shaft 50 and is held against movement by the side walls of theslot while the shaft is rotated to bring the blocks around against the wire. As the blocks come around they strike against the ends of the wire projecting beyond the sides of the post and bend them over at right 5 angles, and the bent portions enter the grooves 8 and as these groovesare curved to conform to the periphery of the shaft the said angular ends will as they are drawn through the grooves, be caused to assume a similar curve and will thus produce the completed article 1. After the shaft has been turned a sufficient distance to form the fasteners the motion is reversed to bring the parts again to normal position; and in order to throw out 6 the completed fastener I provide spring arms 9 secured to the shaft and having angular bent ends 9 which, in the first or forward movement of the shaft may ride over the ring portions of the fasteners, but when the shaft is reversed pass under the said rings and'by their spring action throw out the fastener 1 as soon as the rings are released from the overhanging. portions of the blocks.

Having thus described myinvention, what 7 5 I claim is- I 1. A machine for making window-shade fasteners and the like from straight lengths of wire, consisting of a revolving shaft, means for holding the central portion of the wire in proximity to the periphery of the shaft, and means carried by the shaft for engaging the projecting ends of the wire to bend them at right angles to the central portion and cause them to conform to the curve of the shaft, substantially as described.

2. .In combination, the post having an opening therein with a slot leading to said opening for receiving a wire, a shaft journaled in said opening, and blocks or projections carried by said shaft upon each side of the post having grooves or recesses for engaging the free ends of the wire, substantially as described.

3. In combination, the post having an open- 5 ing therein with a slot leading to said opening, for admitting a wire, a shaft journaled in said opening, blocks or projections carried by said shaft upon each side of the post for engaging the projecting ends of the wire, and

projecting beneath the bent portions on the wires on the reverse motion, whereby the completed fastener is automatically thrown out on the shafts resuming its initial position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

means for throwing out the completed fastener when released by said blocks or projections, substantially as described.

4. In combination with the post having a shaft oscillating therein and a slot leading to the periphery of the shaft to admit a wire, means carried by the shaft for engaging the projecting ends of the wire to bend them around the shaft in a plane at right angles to Witnesses:
