COIL AND COP-HOLDER FOR WIRE-NETTING MACHINES.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed July 6, 1905. Serial No. 268,463.

To all whom it may concern:

, Be it known that I, ARTHUR E. BARLOW, a citizen of the United States, residing at Vorcester, in the county of /Vorcester and State of Massachusetts, have invented a new and useful Cop and Cop-Holder for Vire- Netting Machines, of which the following is a speciiication.

This invention relates to that class of machines which are employed for making chicken coop wire netting.

The especial object of this invention is to provide a strong, simple and efficient form of cop and cop-holder having means for locking the same in place against accidental displacement, and which are pivoted so that they can turn with comparatively little friction.

To these ends this invention consists of the cop and cop-holder and of the combinations of parts therewith as hereinafter described and more particularly pointed out in the v claims at the end of this specification.

In the accompanying drawing, Figure l is a transverse sectional view of sumcient parts of a wire netting machine to illustrate the application of this invention thereto. Fig. 2 is an enlarged sectional view partly broken away of sufficient parts of a machine to illustrate the application of a cop and cop-holder thereto. Fig. 3 is a side view 'of the cop partly broken away. Fig. 4 is a side view of the cop-holder partly broken away. Fig. 5 is a fragmentary view similar to Fig. 2 showing the locking catch unfastened so as to permit the cop and cop-holder to be inserted into or taken out of the machine, and Fig. 6 is a detail view of a division piece for the cop showing a guide piece for the wire.

. In machines which are used for making the so-callec chicken coop netting, one half of the wires are taken from reels or other sources of supply, while alternate wires are furnished from cops or bobbins. The copholders are mounted in bearings in top and bottom twisting gears. The top and bottom twisting gears are made in half sections and are shifted transversely between the making of successive twists, so that a wire from any one cop is twisted alternately with the reel wires at the sides thereof. In this class of machines the cops and cop-holders are the parts which give the most trouble. In most of the machines the cop-holders are simply dropped into place in bearings in the twisting gears, and it sometimes happens that a number of such cop-holders will become displaced from their bearings and will drop out of position in the machine, requiring the stopping of the machine and the replacement of the parts. In these machines, also the cops and cop-holders must be mounted so that they will turn readily upon their bearings, permitting wires to be supplied as fast as required without breaking or kinking.

In a wire netting machine equip ed according to this invention each of t e copholders is held in place in its bearings by means of a simple and efficient locking device which will prevent the cop-holder from being accidentally displaced, while permitting it to be readily unlocked and taken out whenever the cop or bobbin thereof requires refilling. The cop and cop-holder are supported upon a step bearing which is preferably provided with a bearing ball in an oil socket which contains suflicient oil to keep the bearing well lubricated.

Referring to the accompanying drawing for a detail description of a cop and copholder constructed according to this invention, and of sufficient parts of a wire netting machine to illustrate the application of this invention thereto, as shown in Fig. l, A designates one of the end frames of a wire netting machine. Mounted upon and supported by the frames A are fixed top and bottom gear rails R and R. Coperating with the fixed gear rails are movable gear rails M and M. Mounted in the rails R and M are the top split twisting gears, one-half of each of which receives one of the reel wires, and the other half of each of which is provided with a downwardly extending bearing S for engaging the top of a cop-holder. Mounted in the rails R and M are the bottom split twisting gears one-half of each of which receives one of the reel wires W, and the other half of each of which is provided with an upwardly extending step Sfor supporting the cop and its holder. The netting as fast as made is fed out by a feed roll F, and may be rolled up or delivered in any of the usual ways. The parts as thus referred to may be of any ordinary or usual construction and need not be herein described at length.

The cop and its holder which I have devised is most clearly illustrated in Figs. 2 to 6 inclusive. As shown in these figures, the cop-holder consists of a tube 10 having an upper slot 11 and a lower slot 12. These slots are provided for the purpose of permitting the operator to see where the wire is, and Vfor convenience in threading the wire into place. Mounted in the tube 10 and pinned rigidly in place therein is a division piece 13. Mounted in a socket in the piece 13 is a springn pressed pin 14 which is held in place by a cover-plate 15. Pivoted on the covenplate 15 is a bell-crank locking lever 16, one leg of which is engaged by the spring-pressed pin 14. At its upper end the tube 10 ci the copholder iits onto the bearing S. The copor bobbin as herein illustrated, comprises a tube or bobbin 17 having a headlS at its upper end. The bobbin head 18 is provided with a pivot pin or pintle 19 engaging the center hole of the division piece 13. Fastened in the lower end oi the pipe 17 is a step 2O which is provided with a counter-sunk socket for resting on a bearingeball 21 mounted in an oil well in the step S. The wire W which is wound on the bobbin extends out through the slot 11 as shown in Fig. 1, and in passing the collar or piece 13 the wire N preferably runs in a guide piece 22 illustrated in Figs. 4 and 6. It is shown extending out through the slot 11 for convenience only, as in prac tice the wire does not project through the slot in this way. rlChe guide piece 22 consists of a small trough-shaped piece of hardened steel which may be vfastened in place by one or more screws 23. rllhe guide piece 22 is preferably highly tempered, so that it will not be worn or cut by the wire which is drawn up through the same.

1n the operation of a netting machine equipped according to this invention, whenever it is desired to remove a cop and its holder, the locking lever 16 may be released by inserting a rod through the upper part of the slot 11, and when the locking lever is released the cop and the cop-holding tube may be lifted as shown in Fig. 5, so that said parts may be taken out lfrom the machine, land if desired a new cop-holder inserted.

l/Vhen the parts are in normal position, as illustrated in Fig. 2, the -cop and cop-holder will be securely locked in place so that they cannot be `accidentally displaced, while the weight of each cop and its cop-holder rests upon a thoroughly lubricated bearing ballso that the same can be readily turned without breaking or kinking the wire.

l am aware that various changes may be made in the construction of my cop and copholder in applying them to diil'erent makes and arrangements of wire netting machines.

1 do not wish, therefore, to be limited to the 'construction 1 yhave herein shown and described, but

Vhat l do claim and desire to secure by Letters-Patent of the United States is 1. 1n a wire netting machine, the combination of a cop, a cop holder, and a locking device for the holder comprising a bell-crank mounted in the upper part of the holder and adapted to engage a bearing extending down from an upper twisting gear` to lock the holder against a rising motion in the bearings.

In testimony whereofl l have hereunto set my hand7 in the presence of two subscribing witnesses.
