Application ined December 2, 191e.

To all whom 'it may concern Be it known that I, CLARENCE ARTHUR` Kxownnniin, a British subject, residing at have invented certain new and useful lmprovements in lVire-Netting Machines; and

hereby declare that the following is a full, clear, and exact description of the saine,

My invention relates to a wire netting inachine comprising twisting and drivingv elements so arranged that the mesh wires will be twisted around longitudinally arranged strand wires, and one of the objects of my invention is to so construct the machine that the strand wires will pass axially through the driving elements and be prevented thereby from being' entangled with the twisting mechanism.

A further object of my invention is to so construct the driving and twisting elements that they will converge in the direction of the mesh roller, this convergence creating a tapering formation of the driving elements, which permits of the employment of conical shaped cop tubes with increased cop holding capacity without a corresponding increase in the width of the wire netting, the cop tubes extending through the twisting mechanism to permit of the wire cops being readily placed therein without the necessity of removing said cop tubes from the machine.

ln carrying out these objects I have made the driving elements of a tapering shape, and have formed through each of the driving elements an axial bore extending from one end to the other, and have mounted these driving elements in suitable bearings,

which are so constructed as to resist the end thrust of the driving elements and their related parts, and I have provided the driving elements with trunnions on which are slidably keyed clutch members to engage with the clutch members of the driving pinions loosely mounted upon the trunnions yand meshing with a rack by which motion is transmitted to the driving elements when the clutch elements are engaged, and I have so arranged these clutch elements that when the rack is moving in one direction it will transmit motion to alternate driving elelments, and cause their rotation, and will on the return motion of the rack cause the rotation of the remaining driving elements.

l have. provided the twisting elements with conical-shaped cop tubes located in vthe intervals between each adjacent pair of driving'elements, and l have extended the bores of the cop tubes through the twisting elements so that the wire cops can be introduced into the cop tubes without necessitating their removal from the machine.

For an understanding of the invention reference is to be had to the following description, and to the accompanying drawings in which Figure l is a plan view of thewire net-y ting machine. Fig. 2 is a front elevation of the machine, y Fig. 3 is a rear elevation, Fig. is a broken sectional view showing the bearings for the driving and twisting `elements, Fig. 5 is av Vsectional view through the driving and twisting elements, on thel line if-a, Fig. 4e, Fig. 6 is an elevation of the bearings for the driving and twisting elements shown in Fig. 5, Fig. 7 is a perspective view of one of thel driving elements,

Fig. 8 is a perspective view of one of the twisting elements, Fig. 9 is a detail view of the levers for moving theclutch members of the driving elements, and Fig. 10 is a broken view of the wire netting.

Like characters of reference refer to like parts throughout the specification and drawings.

On the top of the frame a near the front thereof is a slide way b for the rack c, and meshing with the rack c kare a set of pinions d, cZ,'cZ and d3. These pinions are loosely mounted upon the trunnions e of the driving elements f, f', 7, and farespectively, the trunnions being journaled in bearings g in the gear box L. The gear boX h is fastened lto the frame a above the slide way vY), and the trunnions project through the bearings g to the front of vthe gear box.

The pinions d, ci are each provided,pref

erablv with a ratchet faced clutch member-A 'p z', and the pinions cZ, Z3 areeach provided preferably with a ratchet faced clutch member t', the inclined surfaces of the clutch vmembers e" being reversed with respect to p the clutch members i of the pinions and c ments at the rear end of the machine, where the netting is formed, corresponds to the fidth of the netting, and that the width of the front end of the twisting and driving elements is relatively greater than the rear end, to permit of tapering cop tubes being employed to contain conical shaped cops of wire for forming the meshes. By making these cop tubes of a conical shape it is possible to increase their wire holding capacity without increasing the width of the wire netting.

The tapering formation of the driving and twisting elements in addition to permitting of an increased holding capacity of thel cop tubes, also has the advantage of creating a relatively tight fit of the journals in their bearings as the bearings are tapered to correspond with the taper of the journals, and owing to the action of the mesh roller in drawing the wires through the cop tubes, a strain is imposed on these parts and on the driving elements rearward of the machine, which has the effect of causing the tapering journals to continually bear toward the smaller end of the bearings. To resist the end thrust of the driving and twisting elements the bearings a are provided with thrust shoulders a3 which engage the adjacent side faces of the tapering journals and lunes and thus prevent them binding in their bearings, see Fig. 4.

The rack c is moved back and forth by meansof a lever c fulcrumed to the frame of the machine and actuated by a disk and pin c rotated by a shaft g revolved by bevel gear wheels g driven by the shaft g3.

The mesh roller w is driven from the shaft g3 by an eccentric motion t, and the winding roller e is driven from the mesh roller w by a belt and pulley drive fw".

rIhe above described motions for the rack, mesh roller, and winding roller may be varied within the scope of the appended claims without departing from the principle of the invention.

Having now fully described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is 1. In a wire netting machine, a set of twisting elements, each comprising a tapering tube for a wire cop and lune-shaped members near the ends of said tube, in combination with a set of driving elements each comprising two tapering journals, with lune-shaped recesses in their peripheries to receive the lune-shaped members of the cop tubes, and a connecting member for said journals, said ournals and connecting members being axially bored for the feed of the strand wires.

2. In a wire netting machine, a set of twisting elements, each comprising a tapering tube for a wire cop and lune-shaped members near the ends of said tube, in combination with a set of driving elements each comprising two tapering journals, with. lune-shaped recesses in their peripheries to receive the lune-shaped members for the cop tubes, and a connecting member for said journals, said journals and connecting members being axially bored for the feed of the strand wires, and means vfor causing the.

strand wires, and means for causing the revolution of the alternate driving elements and all the twisting elements, said means comprising trunnions projecting beyond the journals at one end of the driving elements, pinions with clutch members loosely mounted on said trunnions, clutch members .slidably keyed on said trunnions and engaging those of said pinions, and a rack meshing with said pinions to cause their revolution.

4. In a wire netting machine, a set of twisting elements, each comprising a tapering tube for a wire cop and lune-shaped members near the ends of said tube, in combination with a set of driving elements, each comprising'two tapering journals. with lune-shaped recesses in their peripheries to receive the lune-shaped members for the cop tubes, and a connecting member for said iournals`l said journals and connecting members being axially bored for the feed of the strand wires, and means for causing the revolution of the alternate driving elements and all the twisting elements, said means comprising trunnions projecting beyond the journals at one end of the driving elements, pinions with clutch members loosely mounted on said trunnions, clutch members slidably keyed on said trunnions andv yengaging those of said pinions, and a rack meshing with said pinions to cause their revolution, the clutch members of the alternate driving elements being oppcsitely disposed whereby one half the number of driving elements will be revolved as the rack moves in one direction, and the other half will be revolved as the rack moves in the opposite direction.

5. In a wire netting machine, a set of twistingelements each comprising a tapering tube for a wire cop and lune-shaped members near the ends of said tube, in combination with a set of driving elements,

eaeli comprising tWo tapering journals, with lune-shaped recesses in their peripheries to receive tlie lune-shaped members for the cop tubes, and a connecting; member for said journals, said journals and connecting members being' axially bored for the feed of the strand Wires, means for causingthe revolution or' the alternate driving elements and all the twisting elements, said means comprising trunnions projecting beyond the journals :1t one end of the driving elements, pinions with clutch members loosely mounted on said trunnions, clutch members slidably keyed on said trunnions and engaging those or' said pinions, and a rack meshing with said pinions to cause their revolution, the clutch members of the alternate driving elements being oopositely disposed, where* by one half the number of driving elements Will be revolved as the rack moves in one direction, and tbe other half will be revolved as the raeli moves in the opposite direction, and means actuated by the clutch members or' the alternate driving elements tor moving the eluteli members of t ie remaining driving elements into engagement at each reversal of tlie movement of said rack.
