MACHINE FOR WEAVING COVERINGS FOR WHIP=HANDLES.v

Speoiii cation forming part of Lettersiatent No. 52,718, dated February 20, 1866.

l'o all whom it may concern:

Be it known that I, LIVERAS, HULL, of Charlestown, of the county of Middlesex and State of Massachusetts, have invented a new and useful Machine for Making the Coverings of Whip-Handles; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure l is a top view, Figs. 2 and 3 are side elevations, and Fig. 4 is a vertical section, of it.

The said machine is intended to wind one or more threads in a helix around a whipstock and to connect the coils of the helix by other threads bent or twisted together on each helix. These connecting-threads while being interlaid with the covering-threads may by the machine be caused to arrange themselves in helices going about the whip-handle.

In the drawings, A denotes the frame of the machine, it being suitably made for giving support to the operative parts.

The rst constituent portion of the machine is"a mechanism for sustaining a whip-stock or article to be covered and moving it vertically, as circumstances may require.

In the drawings the whip-stock is represented at B as having its butt or larger end inserted in a socket, or in the upper end of a vertical rod, C, which is so supported within bearin gs b c as to be capable of being revolved and moved lengthwise therein. The lower part of the rod has a series of grooves formed around itat equal distances apart, as seen at d. A pinion gear, e, engages with these grooves, which form a cylindrical rack, such pinion being fixed on a tubular shaft, 0', which revolves on a horizontal shaft, f, that receives rotarymot-ion from a driving-shaft, g, by means of a train of gears, 7L t', an upright shaft, k, a

plied to the shaft s', and the gear u', serves to engage the said gear u with the shaft s', as occasion may require.

By means of the worm c', the gear uf, the shafts', the cone-pulleysp q', the endless band r', the shaft o', and the gear e an upward vertical motion may be imparted to the rod or shaft C and a whipstock when fixed therein, and the degree of the motion may be varied by shifting the belt on the cone-pulleys.

The next constituent part of the machine is the mechanism for winding one or more threads in a helix about the whip-stock during its` upward movement, the same being described as follows:

A bent arm, D, projects from an annulus, E, arranged horizontally and on the frame of the machine. This annulus serves to support the spindles m mof two or any oth er suitable number of spools, a a, from which, when the machine is in action, threads pass to and through an eye at the inner end ofthe arm D, and from thence to the whip-stock. By giving` arotary motion to the annulus E the threads will be moved about the whip-stock during its upward movement. This rotary motion of the annulus E is effected by means of gears o p, one of which is aiiixed to the annulus and the other to the upright shaft k.

The next portion or constituent part of the machine is a mechanism for laying the binding or connecting threads about the helixcoils, the machine, as represented in the drawings being made to exhibit four sets of such mechanism. There may be more or less of them,as circumstances may require. As they are alikein action and construction, the description of one of them will suffice to answer for all. In eachentire revolution of the thread-carrying arm D it will pass through each of these sets, so as to lay its thread or threads successively into the angles of decussat-ion of the threads of the said sets, and immediately or soon after the threads have been so laid between any two of the binding-threads of any one set, as above described, such set will be revolved so as to lay the binding-thread around the covering-thread or threads and twist such binding-threads together.

Each of the said sets has a pair of two separate dier-frames, q r, each of which is provided with a semi-cylindrical journal, s. These semi-journals are supported in semi-boxesv extends to the whip-stock.

t u, one, lt', of which extends down from a stay tionary annulus, o, while the other is supported So as to be capable ot' being moved up and down, the downward movement being effected at the proper time by a cam, fw, which projects from the rotary annulus E, and works against a stud, a', extended from the shank y of the semi-box. A spring, z, applied to such shank serves to effect the upward movement of the bearings. Each of the said semi-journals carries two half-gears, a b', arranged on it, as represented. A train of two gears, c d', is applied to each flier-frame. One of such gears is fastened on the end of the l'lier, and the train engages with the inner semi-gears, b b, and during rotary motion of the pair or flier-frames q roperates toproduce a rotary motion ot' these iiiers. This rotary motion of the dier is for the purpose of preventing` the thread of its bobbin from becoming further twisted.

Each flier carries a spool, e', supplied with a proper thread-tensioner and delivering ap paratus, f, through which the thread passes from the spool to and through the nose of the liier, and from thence through the nose g of the flier-frame. From the latter'the thread To the annulus E a curved rack, 7L', is fastened. This rack, during each revolution ofthe said annulus, engages in succession with the external pairs of semi-gears of the several pairs of iiier-flames, and produces a revolution of each ofthe said frames. The thread-carrying arm D, during its circuit of revolution, passes between each pair of Hier-frames, the lower frame of such pair being moved downward or away from the upper frame to.allow of the passage of the arm D between such frames. After the arm D, carrying the covering-thread, may have so passed each pair ot' Hier-frames, so as to carry the threads into the vertex of the angle between the two binding-threads of such flier-frames., the said Hier-frames arc to be revolved so as to interlock their threads or twist them ou the covering-thread.

If the whip-stock be simplymoved vertically during the operation of' working the covering on its handle, the binding-threads would lay on it in vertical courses or ranges; but in order that each of them may be laid on it in a helix, the whip-stock should have a proper rotary motion while heilig moved vertically. The machinery for et't'ectin g this is an auxiliary to the main part or combination on which my invention is based, and may be thus described.

A friction-clutch, h2, operated by a lever, t', is xed on the shaft or rod C, and engages with a beveled wheel, 7c', which is placed on and so as to be capable of freely revolving on the shaft c. This beveled gear is revolved by another beveled gear, l. and the gears h t', the latter-viz., lbeing fixed on the shat'tf.

When the clutch h2 is out of action on the bevel-gear 7c such gear will be freely revolved on and will produce no rotary motion of the shaft or rod C, but when the clutch bears on the wheel and the latter is in the act of being revolved the rod C will be slowly rotated.

The machine when in operation without the whip-handle or its equivalent placed within it will make a braid or cord.

I claim as my inventionl. A mechanical combination comprised not only of machinery for sustaining a whip-stock or other article and moving it lengthwise and mechanism for winding one or more threads in a helix about the whip-stock or article while being s0 moved, but also of mechanism for laying binding or connecting threads about the helix-coils, the whole being sul'istantially as herein before described.

2. In combination therewith, mechanism for revolving the whip-stock so as to cause the binding or connecting threads to be laid in a helix thereon, as set forth.

LIVERAS HULL.
