FENCE-MACHINE.
SPECIFICATION forming part of Letters Patent No. 549,946, dated November 19, 1895. Application filed February 25, 1895. Serial No. 539,662. (No model.)
T at whom it may concern.-
Be it known that I, NELSON J. TUBBs, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Fence-Machines; 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 made and use the same.
My invention relates to improvements in fence-machines and the invention consists in the combination of a frame carrying an endless chain, sprocket-wheels operated by said chain, Wire-twisters pivoted in said sprocketwheels so as to allow the machine to remain perpendicular no matter What inclination the wires may assume, and means for operating theendless chain.
It also consists in the combination of a bar,
, sprocket-Wheels adjustably mounted at each end of the same, an endless chain passed about said wheels and bar, wire-twisters operated by said chain and being capable of being slipped off the wires at will, means for operating said chain, and a wheel attached to the lower end of said bar.
It also consists in the combination of a frame carrying an endless chain, sprocketwheels operated thereby, wire twisters mounted in said sprocket-wheels, means for operating the sprocket-chain, and a wirestretcher and tension-varying device connected to said wires.
It also consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter more particularly set forth and claimed.
In the accompanying drawings, Figure 1 represents a side elevation of my wire-twisting device. Fig. 2 represents a central vertical section of the same. Fig. 3 represents a detail end elevation of the upper end of the frame carrying the adjustable sprocketwheel. Fig. 4 represents a detail side elevation of the lower end of the frame carrying the traction and sprocket wheels. Fig. 5 represents a side elevation of the devices embodying my invention as they appear during the construction of a fence. Fig. 6 is a detail central vertical section through one of the sprocket wheels carrying the pivoted wire-twister, also showing the sprocket-casting and fence-pickets. Fig. 7 represents .a top plan View of the same. Fig. 8 represents a side elevation of the wire-stretcher and tension device. Fig. 9 represents the same with the end of one of the pivoted arms broken away' to expose the winding-drum and its ratchet-wheel and ratchet. Fig. 10 represents a top plan View of said wire-stretcher and tension device, and Fig. 11 represents a side elevation of the key for operating the ratchet-wheel of the combined wire-stretcher and tension device.
A in the drawings represents the bar forming the frame of my machine; B, the endless sprocket-chain; O C, the sprocket-Wheels supporting said chain; DDD the sprocketwheels carrying the pivoted twisters 5 E, the operating-handle for actuating the endless chain, and F the wire-stretching and tension device.
The bar A is preferably made of wood and is provided at each end with a longitudinal slot a, said slots being adapted to receive the respective shanks c c of the castings G G that support the sprocket-wheels O O.
The casting G is provided with a yoke,within which the wheel C is mounted, and the shank c of said casting is slotted at f, so that the bolts g, that confine the shank in the slot a, will not prevent the casting G from being adjusted either up or down. The cast-ing G is similar tocasting G, except that its yoke is at right angles to the yoke in the casting G and has a traction-wheel H mounted therein, the sprocket-wheel 0 being mounted in a slot h intermediate of said yoke and the shank c. The endless chain is passed about the sprockets C 0, thus causing it to lie about said bar on opposite sides thereof.
The sprocket-wheels D D D are respect ively mounted in castings I, which are each composed of two circular parts provided with attaching-arms i,'said parts being adapted to be attached to the opposite sides of the bar A and be bolted together at their outer edges,and thus inclose their respective sprocket-wheels between them.
Each one of the sprocket-wheels is composed of a rim K,provided with sprocket-teeth k, annular lateral flanges it, and laterallyextending buffers 10 The rim K is adapted to be confined between the parts of the casting 1, and thus prevent lateral motion of said wheels, while the annular flanges 7c prevent vertical movement of said wheels.
\Vithin each sprocket is pivotally mounted a wire-twisting device M, which consists of a bar provided with journals m and with lateral projections m 171 the latter being mounted on the bar so as to lie to one side of the surface of the same, so that when the wires are passed along on the outer surface of the projection m they will be behind the inner surfaces of the projections m and said wires are thus held firmly on the bar. The sprocketwheels are so mounted in their castings that their inner peripheries always engage the endless chain, and they are thereby operated in either one direction or the other, according to the movement of the chain, and as said sprocket-wheels revolve the wires are twisted together by means of the pivoted bars.
The rims of each of the sprocket-wheels D D D as well as the circular castings I, are provided with a narrow slit or passage j, and when said passages of the wheel and casting are in coincidence, as shown in Fig. 2, the machine can be readily slipped on or off the fence-wires.
The operating-handle E is mounted 011 a shaft e, which carries a sprocket-wheel e, that meshes with the chain 13, said shaft being mounted in a casing E, attached to the bar A.
The wire-stretching and tension device, as shown in Figs. 8, J, and 10, is composed of two pivoted arms 0 and 0', the forward or longer portions of these arms being provided with projecting studs 0 between which the wire is strung in a zigzag manner, so as to cause con siderable friction in moving, and thus the wires are pulled between said studs under tension. The inner and outer stud 011 each arm is provided with a small lateral projection that guides the wire fairly onto the stud and keeps it from slipping therefrom. If it is desired to increase the tension on the wires, the arms 0 0' are spread apart and held so by a wedge 10 or other similar device.
The shorter end of the arm 0 is provided with a stud p, on which is mounted a wirestretching drum P, provided with a ratchetwheel P, adapted to be engaged by a gravitypawl p.
A wire Q, attached to any stationary object, is passed once or twice about the drum and then is wound thereon, as occasion requires, by means of a key R, as shown in Fig. 11,which key is applied to the ratchet-wheel to turn the same.
A handle S is provided upon the upper part of the bar A, by which the machine may be held firmly in position when being operated.
The operation of the machine is as follows: The l'nachine is set up in position, as shown in Fig. 5, with the traction-wheel H upon a board or other suitable base, the pairs of wires in their respective twisters and the tension devices adjusted to give the desired tension. The machine is run back a short distance and a picket inserted between the wires. The machine is then run forward until the buffers k strike the picket and force it up snugly to the last twist in the wire. The handle E is then rotated to the right, and the desired distance thus twisted behind the picket, the wires in the meantime feeding through the tension device, but under tension, so that the wire is always kept taut. The next picket is inserted and the operation repeated as before, with the exception that thehandle in this instance is rotated toward the left, and so 011 alternately from right to left, as each successive picket is inserted.
It will be seen that as the chain B becomes loose the bolts g at either the top or the bottom can be loosened and the sprocket-wheels C C adjusted away from each other, and thus tighten the chain.
It will also be observed that by having the twisters M pivoted in the sprocket-wheels I) D D the machine, and consequently the pickets, can always be kept perpendicular, even though the wires be inclined one way or the other because of a hill or the like. This I consider a very important feature of my invention, as by it hills can be fenced with vertical pickets with as much ease as the fencing of level ground.
Any size or shape pickets can be inserted in my fence, either half or whole pickets. In fact, even brushwood or the like could be woven into'the wires, if so desired.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. I11 a fence machine, the combination of a f 'ame carrying an endless chain, sprocket wheels mounted on said frame and operated by said chain, wire twisters adapted to positivcly engage or grip the wires, and pivoted in said sprocket wheels so as to revolve therewith but always on an axis parallel with the wires no matter what the inclination of said sprocket wheels may be, and means for operating the endless chain, substantially as described.
2. In a fence machine, the combination of a frame carrying an endless chain, sprocket wheels mounted on said frame and operated by said chain, wire twisters adapted to positively engage or grip the wires and pivoted in said sprocket wheels so as to revolve therewith but always on an axis parallel with the wires no matter what the inclination of said sprocket wheels maybe, means for operating the endless chain, and an adj ustable wire stretcher and tension device, substantially as described.
3. I11 a fence machine, the combination of a frame carrying an endless chain, sprocket wheels formed of split rings, suitable mountin gs connecting said wheels with said frame, wire engaging and gripping devices pivotal] y mounted in said split rings so as to revolve therewith but always on an axis parallel with the wires no matter what the inclination of said rings may be, and means for operating the endless chain, substantially as described.
4. In a fence machine,the combination with wire twisting devices, of a wire stretcher and tension device consisting of two pivoted arms provided with studs adapted to allow the wires to pass between them under tension and means for increasing or decreasing the distance between said arms whereby the tension on the wires is increased or decreased.
