FENCE-MACHINE..

SPECIFICATION forming part of Letters Patent No. 376,521, dated January 17, 1888.

Application filed November 4, 1887. Serial No. 254,291. (No model.)

T0 all whom, ib may concern Be it known that I, SAMUEL H. GARRETT, a citizen of the United States, residing at Mansfield, in the county of' Richland and State of Ohio, have inventedcertain new and useful Improvements in Fence-Machines, of which the following is a specification, reference being had therein to theaccompanying drawings.

This invention has relation to machines for weaving'picket-and-wire fences, and more particularlyto that class thereof in which a series of twisters are operated by a rack-bar; and among the objects in View are to simplify the construction, reduce the number of parts, and facilitate the manufacture and combining of said parts, whereby a machine is provided at a reduced cost. Y y

Other objects and advantages of the invern,4 tion Kwill hereinafter appear, and the novel features thereof will be particularly pointed out in the claims. y

Referring to the drawings, Figure l is a side elevation of a machine constructed in accordance with my invention, the same being in operative position and in the act of forming a fence. Fig. 2 is a front elevation of thermachine. Fig. 3 is a side elevation of a portion of 'a post provided with a tension device employed in connection with the machine. Fig. 4 is a transverse sect-ion on the linewxof Fig. 2. Fig. 5 is a detail in perspective, hereinA after described, as is also Fig. 7. Fig. 6. is a transverse section on the line y y of Fig. l, Showing the mechanism for holding the machine and picket firmly in place while the twists are being made.

Like letters of reference indicate like parts in all the figures.

A represents the usual nprights, to which and at equal distances apart are secured, by means of bolts B',opposite clamping-plates B. The plates B are preferably cast, and are .formed with bearings B2, in which are journaled the usual perforated and toothed twisters, B3. The ends of said plates are formed at an angle to the remainder of the plate,and are adapted to embrace and form guides for a rackbar, C, interposed between the bent ends and said twisters and adapted to mesh with and rotate the latter. The upper and lower pair of plates B are arranged with their terminal ends near or in contact with each other, and' against said plates are designed to abut stops C', arranged near each end of the rack-bar C, so that its upward and downward movement is limited, by which the requisite number of gear is operated by a crank, D4, affixed to the opposite end of the shaft. The twister employed with this pair of platesalso differs from the remaining twisters in that its hub or boss is provided with a initer-gear, B4, adapted to mesh with the gear D3, just described. In this manner, by rotating thehandle D4, motion is imparted to the shaft' and gear D3, thence to the gear BL and its twister B3, and to the rack-bar C, and the remaining twisters, all clearly shown in Figs. 1 and 2 of the drawings, E representing the pickets around which the strands of wire are being woven.

In Figs. 1, 6, and 7 I have shown a device for holding the machine firmly in place while the twists are being made.

F represents an angular casting or plate, which is adapted to bebolted to the front of the upright A and extends around to one side and has formed thereon ears or lugs F', which form bearings for a toothed sector, F2, the teeth of which are adapted to take .into and thus operate the arm or clasp F3, having perforations along its vsurface in which the teeth of the sector F2 operate. Upon the opposite angle of the plate Fare formed guides or ways Ft, by which the forward bent end of the clasp Fa is held in rear of the machine.

A picket E having been placed in position, the machine is operated until the rack-bar C has reached that point where one of thel stops C comes into contact with the clamping-plates at the top or bottom of the machine. The machine is then moved forward and another picket is placed in position between the wires. The last picket that was woven in is caught by the clamp, and by swinging the sector-lever IOO until the teeth thereof take into the apertures of the clamp-bar the machine and last-ad- Y justed pichet are held firmly in their place.

The crank of the machine is then revolved in a reverse direction until opposite stop, C', abuts against the clamping-plate at the opposite end ofthe machine.

The sector F2 is provided with a plain face, so that when swung` upon its pivot until said face is adjacent kto the spacing-bar said bar may be freely slid within the ways F, and can be held at any point by simply swinging the sector-lever until the teeth thereof take into the teeth of apertures in the clamp-bar. By this device the twisting ofthe wire between the pickets is rendered uniform andcan be done with perfect ease.

Referring to Fig. 3 of the drawings, G represents in this instance one of the posts comprising the felice or other suitable support, and H a tension device, a series of which are to be mounted on said posts er support in ad Vance of the machine; or it may be upon any other post, the number of tensions being in accordance with the number of twisters employed in the machine.

The tension consists of a simple casting or plate, H', perforated and adapted to be secured, by screws or other fastening devices, to the face ofsaid post. An opening, H2, is formed in the plate, and at either side thereof within said plate are formed parallel grooves Il, through which thestrands I ofwire are adapted to pass ou their way to the machine. A button, II, is secured tc the post in the center of of the plate, or it may be to the plate, which will bind upon the strands and provide and maintain sufficient tension. By theprovision of the parallel grooves H the strands of wire are prevented from being bent, which, if done, would necessarily impede their easy passage through the apertures inthe twisters. This tension may be light or heavy, it being gradu ated by screws H5, passing through the button.

It is apparent that all of the plates, &c., composing the machine maybe easily east and assembled, and this without any special hand or machine finishing.

Having described my invention and its operation, what I claim is l. In a feneemaehine, the eombinatiomwith the upright A, having the plates B bolted thereto, said plates being bent at their ends and having the gear-twisters B3 ]'ournaled therein, of the raelebar C, embraced by said bent ends,and having stops C arranged thereon and adapted to limit the movement ofthe bar by coming into contact with the said bent ends, substantially as specified.

2. In a fence-machine, 'the combination,with the upright A, having the plates B and geartwisters 15x, and the rack-bar G, embraced by said plates and meshing with the twisters, of the plates l) and D', the former havi ng the bearing D2 formed at a right angle thereto and earrying the gear D and handle D4, the twister Bi, mounted in said plates, and the gear B2 mounted on the twister and meshing with the gear D, substantially as specified.

3. In afence-machinc, thecombination, with the upright A, ofthe casting F', carrying the sector lf2, and having the ways h", and the clamping-bar Il, mounted in said ways and adapted to mesh with said sector, substantially as specified.

et. Inafence machine, the combination, with the upright A, ol" the casting F', having guides Ii, the clamping-bar F", mounted therein, and the lugs or ears F', carrying theseetor F, having the toothed and plain faces, substantially as specified.

5. The combination, with the fence machine and its twisters, of the tension II, consisting ofthe plate l-I', having the cent-ral opening, H", and parallel grooves Il, for carrying the wires, and the button Hi, adapted to bind upon said wires, substantially as specified.

G. In combination with a fence-machine and the post G, a tension device comprising the securing-plate H', having the central opening, H2, and grooved, as at H3, and the button H4 and its screw H5, substantially as specified.

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