ARTHUR E. BARLO'W, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO THE W'RlGI-IT & COLTON \VIRE CLOTH COMPANY, OF SAME PLACE.

COP-HOLDER FOR WlRE-NETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 554,358, dated February 11, 1896. Application filed July 7, 1894. Serial No. 516,804 (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR E. BARLOW, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in a Cop-Holder for ire-Netting Machines, of which the following is a specification, accompanied by drawings forming a part of the same and representin g so much of a netting'machine as is necessary to illustrate the nature of my present invention and its method of operation.

My invention relates to certain improvements in a cop-holder designed to be used in a wire-netting machine provided with twisting-gears made in halves and actuated by reciprocating racks in the usual and well-known manner common in machines of this class, and ,in the accompanying drawings I have not deemed it necessary to show in detail the construction and operation of the parts of a wire-netting machine not directly concerned in my present invention, as they will be well understood by all persons familiar with wirenetting machinery.

Figure 1 represents an end view of the framework of a wire-netting machine shown in section on the plane of one of the bobbin-hold ers, the twisting-gears, reciprocating racks, and take-up roll being the only portions of the operating parts of the machine represented in the drawings, the bobbin-holder embodying my improvement being shown in central sectional view. Fig. 2 represents a detached view of the bobbin-holder and twisting-gears, and Fig. 3 represents a central vertical sectional view of the parts shown in Fig. 2.

Similar letters refer to similar parts in the several figures.

Referring to the drawings, A denotes the framework, B the take-up roll, and C O the reciprocating racks by which the twisting gears are rotated.

D D and D D are bars supported by the framework in which the twisting'gears are journaled, the twisting-gears being made in halves and the bars D D being stationary, and the bars D D capable of a sliding motion by which the one-half of each twistinggcar is shifted in the usual and well-known manner, all the above-described portions of the machine being constructed and operating like the similar portions in the wire-netting machines now in common use.

The lower twistinggears, journaled in the bars D D, are formed of two half-sections E and E, the section E having a hole aextending through it to allow a wire a to pass, the

upper end of the section E having a horn a standing obliquely to the axis of the gear through which the hole a is continued in order to carry the Wire a away from the copholder. The section E of the lower twisting- .gear extends above the bars D D in the form of a spindle E having its upper end hollowed or recessed to form a step-bearing E upon which the cop-holder is supported.

The upper twisting-gears j ournaled in the bars D D consist of the half-sections F and F, the section F being provided at its lower end with an oblique horn a through which and the gear-section F is a hole a to receive the bobbin-wire a. The half-section F ex tends below the bars D D, and is recessed to 7 5 form a journal-bearing F for the upper end of the cop-holder, and from the bearing F a hole extends through the half-section F to receive the wire Z2 taken from the cop G.

The cop-holder which embodies my present invention is supported at its lower end upon the step E and at its upper end by the journal-bearing F and it comprises two separate pieces, namely: a bobbin G, upon which the cop of wire G is wound and consisting of a piece of pipe G provided with a conical head G the outer surface of the hollow pipe G and head G being preferably slightly corrugated to prevent the slipping of the wire wound thereon. The lower end of the pipe G 0 is provided with a steel block G which rests in the step-bearing E WVithin the pipe G is placed a spindle H, upon which the bobbin G is capable of turning freely, the spindle H forming a support for the upper end of the 5 bobbin. The spindle I-I passes through and is attached to a head H, the upper end of the spindle being inclosed and capable of rotating freely within the journal-bearin g F Attached to the head H is a cylindrical hood H provided with a slot H The upper end of the spindle H is hollow and is provided with a hole H communicating with the interior of the spindle. For convenience of construction I usually make the spindle II from a piece of gas or steam pipe and bore the hole H communicating with the interior of the pipe. From the j ournal-bearing F a hole b extends through the gear-section F in alignment with the axis of the spindle H. The hood II extends from the head II downward over the cop G, and the cop-wire b is taken from the cop G through the slot II in the hood, through the hole H to the interior of the spindle II, and then upward through the hole I), the copwire I) being delivered at the upper end of the ear-section F contiguous to and parallel with the bobbin-Wire a, so they will be twisted together by the rotation of the twisting-gears in the usual and well-known manner.

The twisted fabric is carried over the take up roll 13, which is intermittently rotated at the end of each twisting operation to draw the wires a b upward in order to form a succeeding series of twists. As the cop-wireb is drawn up it will be unwound from the cop G, either by the independent rotation of the bobbin "G due to the draft of the wire on the bobbin or by the independent rotation of the head II due to the draft of the wire against the edge of the slot H the bobbin G and hood H being capable of rotating independently of 'each other.

The lower end of the bobbin G and the upper end of the spindle E are inclosed by a sliding sleeve I, which is supported upon the end of a spiral spring I, having its lower end resting upon the upper end of the 'gear-section E, the sliding sleeve I serving to break the joint between the spindle E and the lower end of the bobbin and hold the end of the bobbin upon the step-bearing. WVhen it is desired to remove the-end of the bobbin from the step-bearing, the sleeve I can be moved downward, compressing the spiral spring I.

The sliding sleeve I and spiral spring I are inclosed by an outer sliding sleeve J, which rests upon the upper end'of the gear-section E and is capable of being raised over the bobbin G in order to allow access to the sleeve I.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a wire-netting machine, the combination with upper and lower twisting-gears, of a cop-holder comprising a bobbin supported at its lower end in a step-bearing on the lower of said twistingears and having its upper end journaled on a spindle, a spindle entering said bobbin and capable of turning therein and having its upper end journaled in the upper of said twisting-gears, and a hood carried by said spindle and provided with a slot, substantially as described.

2. In a wire-netting machine, the combination of the gear-sections E and E, said section E having a step-bearing, a bobbin G supported bysaid step-bearing, gear-sections I and F", said section I" having a journaled bearing F a hollow'spindle I-I having its upper end journaled in said bearing-and its lower end journaled in said bobbin, and a hood II carried by said spindle and having a slot H substantially as described.

3. The combination of gear-section E having a spindle E and a step-bearing E, a bobbin G supported by said step-bearing, a sliding sleeve I extending over the end of said spindle E and said bobbin, and a spring I supporting said sleeve, substantially as described.

4. In a wire-netting machine, the combination of a gear-section E having a spindle and a step-bearing E, a bobbin G supported by said step' bearing, a sliding sleeve I, a spring I supporting said sleeve, and an outer sleeve .I inelosing said sleeve I and spring I, substantially as described.

Dated this 4th day of July, 1894.
