IMPROVEMENT IN WIRE-BARBING MACHINES.

Specification forming part of Letters Patent No. 196,313, dated October 23, 1877 application filed July 28, 1877.

To all whom it may concern:

Be it known that I, DANIEL O. S'rovER, of Freeport, Stephenson county,-State of Illinois, have invented new and useful Improvements in Machines for Wrapping Barbs on Fence- Wire, of which the following is a full description, reference being had to the accompanying drawing, in which Figure 1 is a plan view. Fig. 2 is a side elevation.

This invention relates to machines for Wrapping wire barbs on fence-wire, and is an improvement on a machine for which Letters Patent of the United States were issued to H. VVflPutnam, February 15, 1876. In such machine the movement of the main wire is not continuous, but this wire remains stationary while the barb is being wrapped thereon, and the wrapping devices must be stopped after the completion of each barb to allow the main wire to be advanced the required distance before receiving another barb.

The object of this invention is to so con- I struct the machine that the movement of the main wire can be continuous, the barb being wrapped thereon while it is in motion.

It consists, chiefly, in giving the rotating shaft which carries the wrapping pin or lug a reciprocating motion with its spindle, in addition to the slight reciprocating movement which such shaft in the Putnam machine has on its spindle, this shaft and its spindle being so constructed and connected with the machine that after a barb has been wrapped onto the main wire they will recede with all the wrapping devices, and then advance ndth such devices, the operation of wrapping being performed while the main wire is in motion, the forward movement of the shaft and spindle being in unison with the movement of the main wire.

It further consists in so connecting the wrapping-pin that it has a reciprocating movement independent of the shaft, so that it can be antomatically drawn back and put out of operation after the completion of each barb, to permit the barbs to pass freely.

In the drawings, A represents a table, or the bed of the machine. B is the main drivingshaft. O is a sliding head. As shown, it is provided with slots a a, through which pins pass, which are secured to the bed A, serving as guides for the sliding head. D is a pitmanrod, connected at one end with the head 0,

and pivoted at the other end upon the outside of the wheel, which is fixed on the end of the shaft B.

Instead of this pitman-rod and wheel I), a cam could be used, located on B, and arranged to run in contact with a projection on or extension of the head 0, for the purpose of advancing the head, which, in such case, could be made to recede by means of a spring or other suitable device.

E is a spindle, permanently secured upon the head 0 beneath the block I F is a shaft on the spindle E, on which it has a slight reciprocating movement independent of such movement with the spindle and head 0.

I) is a wrapping pin or lug, which passes through a head, N, on the shaft F, and has a f" reciprocating movement therein. (1 is a curved lever pivoted to the shaft F. One end of d is connected loosely with the pin b, being located, as shown, between two collars or projections, e, on the inner end of the pin. The other end of the lever is arranged to engage at intervals with one edge of a cam or some projection on the head 0, for the purpose of withdrawing the pin 1). f is a coil-spring, which throws the pin out again. when the lever d leaves the said recess or projection. g is another coil-spring around the spindle, so arranged as to hold the shaft F out as far as it can go on the spindle E, except when it is forced back during the winding of a barb on the main wire.

G is a cog-wheel on the shaft F, which en gages with another cog-wheel, H, on the shaft I, which is supported in bearings h. This shaft I is driven by a bevel-wheel on B, which engages with another bevel-wheel on the end of I. As shown, the wheel H slides on its shaft I in unison with the movement of the sliding head 0, which is accomplished by means of pins in the side of the head, one on each side of H, thus carrying it back and forth on I as O recedes or advances. This wheel H might be made long and secured permanently to the shaft I, in which case the cogwheel G could slide in the cogs on H, producing the same result. When the wheel H is blade secured to J; j is anothercuttingblade Z Z secured to the sliding; head 0.: llhese: cutters: j not? r r lleln t e ed A,: but; :standat 7 an angle thereto; 1

At the same time the shaft F will be in rotation, and the barb-wire, being in position, will be Wound upon the main wire by means of the shaft F and pin I), the main wire and shaft F advancing at the same speed. During this operation the shaft F will be forced back 011 the sphfdle E by the formation of the coils of the barb on the main wire, and the free end of the lever (I will come in contact with some suitable fixture on the head 0, drawing the pin 7) back into the head N on F, releasing the barb-wire from the pin and at the time of the completion of the barb the cutters will sever the barb-wire, and the main wire with the completed barb will pass along the spring g V i s a; cutting.
