BESTOR, OF KNOXVILLE, ASSIGNORS ,BARB-WlRE MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,487, dated August 4, 1885.

Application filed May 13, 1884. (No model.)

To aZZ whom, it may concern:

Be it known that we, CHARLES H. BAKER and FRANCIS L. Bnsron, citizens of the United States of America, residing at Knoxville, in

the county of Marion and State of Iowa, have invented certain new and useful Improvements in Barbire Machines, of which the follow ing is aspeciiication, reference being had therein to the accompanying drawings.

Our invention relates to an improved machine for attaching barbs to fence-wires.

The object of the invention is to obtain a machine by which a large number of barbs may be so attached in a short space of time, the operation of which will prove effective and the construction of which is simple.

To the accomplishment of the above the invention consists of the novel devices and combination of devices, as will be hereinafter described and claimed.

Reference will bemade to the accompanying drawings, in which Figure 1 is an eleva tion of the machine complete; Fig. 2, a section on line 1 1 of Fig. 1; Fig. 3, a top plan of the machine; Fig. 4, an end elevation of parts thereof; Fig. 5, a section of the barbwrapping tube and its support; Fig. 6, an eleva tion of said tube; Fig. 7, a view showing the barb partly wrapped around the wire; Fig. 8, a front elevation of a wrapping-tube; Fig. 9, a sectional detail view of part of the machine; Fig. 10, a detail showing the arrangement of the cutters and their operating mechanism, and Fig. 11 a side elevation of some parts 3 5 shown in Fig. 10.

Like letters refer to like parts in each view,

A represents the main driving-shaft, having hearings in uprights or supports B, and to one end of which driving-pulley O is keyed for imparting motion thereto. Secured to a crosspiece, B, of the frame, as shown in Fig. 1, is an arm, D, the upper end of which enters a notch formed in the hub of a gear-wheel, E, loosely mounted on a counter-shaft, 1?, by

5 means of which arrangement wheel E is held stationary, this arrangement being clearly shown in Fig. 9. This wheel is toothed only a certain distance, as shown clearly in Fig. 2, the remainder of its circumference being left plain, the object of which will be described.

A bevel-gear, F, Figs. 2 and 9, keyed to the lower end of a shaft, G, is so situated that at certain intervals it will mesh with the teeth of wheel E, while during the remainder of the time a friction-roller, H, mounted eccentrically upon the shaft G, will ride upon a camsurface, I, formed upon the wheel throughout the untoothed space thereof, this arrangement of parts serving to prevent the revolution of shaft G as long as the roller H rides upon the cam-surface. Shaft G is mounted in a flange of a wheel or frame, K, keyed to the countershaft 1?, driven from the main shaft through gearing A A and upon its upper end is keyed a bevel, L.

By means of the construction and arrangement of parts thus far described, upon motion being imparted to shaft A, and through it to counter-shaft I, the frame K, keyed to the latter, is carried around, and at suitable 7o intervals the lowerbevel of shaft G, which is mounted in said frame K, meshes with the teeth of stationary wheel E, and revolves said shaft G and the bevel L, keyed to the upper end thereof.

Mounted upon frame K is a series of supports, M, which are provided each with a slot, (1, from their upper ends down to a cir cular space formed in each to accommodate a tube, N, one of said tubes for each pair of supports M. The tubes N are each provided with a slot, 1), which extends the entire length of the tube and in depth to about the center of the same. Farther up on each end of each tube there is provided a wrappingpin, c, the 8 5 object of which will be described.

Surrounding each tube N, at points between its supports, is a bevel, O, which meshes with bevel L, before referred to as keyed to the upper end of shaft G, said bevel 0 being also 0 provided with a slot, (1, which corresponds to that formed in tube N and supports M, the several slots being of a proper size to allow of the insertion or withdrawal of an ordinary fence-wire. 93

By the arrangement thus far it will be seen that at certain intervals upon the revolution of frame K the tubes N will be revolved, and the pins a, formed on the ends thereof, also car ried around.

Keyed to main shaft A is a wheel, Q, provided with a cam-slot, 0, into which a pin, f, of an arm, R, is inserted. Arm R surrounds main shaft A, and at its upper end is hinged to a table or platform, S, which is further supported on uprights I, which surround the counter-shaft P. Upon table S any suitable barb feeding and cutting mechanism is mounted, the parts being so arranged that the barb-wire fed therefrom will be brought directly under the fence-wire.

Although we make no claim in this application to any particular feeding or cutting mechanism, we have shown in Figs. 1 and 3 one form of such and the manner of operating it.

On -the main shaft A there is mounted a bevel-gear, O, which meshes with a similar gear, D, mounted upon the lower end of a perpendicular shaft which has bearing in a box, E, secured to one support 13. Keyed to the upper end of this shaft is a bevel, F, adapted to mesh with a similar gear, G, keyed to a sleeve, H, loosely mounted upon countershaft P. Through the medium of the gearing described and the peculiar-shaped wheel K, keyed to sleeve H, motion is imparted to a wheel, L, secured to one feed-roller, M, motion at the same time being imparted from this lower roller to the upper roller through the medium of suitable gearing, N.

The feed-rollers are mounted upon table S, as also are suitable guides, O, for the barbwires and upper cutters, P.

The cutters P, above referred to, are mounted in cutter-heads T, mounted upon table S, said cutters being placed on a horizontal incline and held adjustably in position by suitable set-screws, as shown in Fig. 10. The lower cutters, V, are mounted in the upper ends of arms Q, said arms being pivoted at their upper ends upon a shaft, W, mounted in cutter-heads T. Gutters V occupy a verticallyinclined position, and are adapted, when arms Q are operated, to force the wires against cutters P and sever the same. Arms Q are connected at their lower ends by cross-pieces X, in which aroller, Y, is mounted. These arms and their roller are so situated that upon the revolution of a wheel, S, carrying projection R, they will be operated.

Motion being imparted to the main shaft, the table S will at certain intervals be oscillated at the same rate of speed as frame K, thereby advancing the barb-wires in the same direction as the wheel K until the same are cut.

Upon frame K there is formed a plate or platform, U, upon which the long end of the barb-wire rests until operated upon by the wrapping-pins.

The operation of the machine is as follows: A fence-wire is inserted into the slots of tubes N, when said slots are in line with the slot; of supports M, and the wire being fed through the tubes, the barb-wire is fed by suitable mechanism, preferably that shown, to a point below said fence-wire and on a line F, to mesh with the teeth of stationary wheel E, and imparts motion to the shaft G, upon which it is mounted,whereby the bevel L upon the upper end of said shaft is revolved, and through the medium of gear 0 rotary motion is imparted to teeth M. As the tube revolves, the wrapping-pins, formed one on each end thereof, come in contact each with a separate barb-wire and proceed to wrap the same around the fence-wire, the cut end of said barb-wire resting upon a support mounted on table S. This operation continues as long as the bevel F meshes with the teeth of wheel E, the parts being so arranged that the tube N will be revolved twice, and the barb wire be wrapped twice around the fence-wire. As the limit of the toothed section of wheel E is reached, the friction-roller H commences to ride upon the cam-surface I of the wheel E, and prevents any further revolution of the tube until the starting-point is reached; and the slots in the tube and its supports being in the same line, the wire is allowed to pass therefrom to the winding-reel, and when the tube reaches the point where the wire is being fed, the slots being in the same position, the

wire is received therein and the operation repeated.

WVe have shown in the drawings a machine provided with five of the tubes described, whereby ten barbs are attached upon each revolution of the frame K; but it will be understood we do not wish to confine ourselves to any exact number, and, further, the details ICO of construction may be varied without departing from our invention.

\Vhat we claim is 1. The combination, with a frame mounted upon a driving-shaft, one or more slotted tubes mounted thereon, and each provided with wrapping-pins, as described, of a partially-toothed stationary wheel and intermediate gearing for revolving said tube or tubes therefrom, as and for the purpose set forth.

2. The combination, with a frame mounted upon a driving-shaft, one or more slotted tubes mounted thereon, and each provided with wrapping-pins, as described, of a partially-toothed stationary wheel provided with a cam-surface, and intermediate gearing for revolving said tubes from the stationary wheel,

as and for the purpose set forth.

3. The combination, with a frame mounted upon a drivingshaft, one or more slotted tubes, each provided with wrapping-pins and mounted on said frame, of a partially-toothed stationary wheel, intermediate gearing for revolving the tubes therefrom, and an oscillating table or platform carrying the barb-feeding mechanism, as and for the purpose set forth.

4. The combination of frame K, slotted tubes N, each provided with wrapping-pins 0, slotf ted gears O, mounted upon said tubes, parping mechanism and table S, carrying suit able barb -wire-feeding mechanism, of linkarm R, provided with pin f, wheel Q, provided with cam-slot e, and means for revolving said wheel, as set forth.

Intestimony whereof we affix our signatures in presence of two Witnesses.
