IMPROVEMENT IN MACHINE :con MAKING conn.

The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom it ma/y concern:

Be it known that I, HARRIS BOAR'DMAN, of Lancaster, inthe State of Pennsylvania, have made certain Improvements on Machines for Making Gord; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of 'this specification, in which- Figure l is a perspective View of the parts in position.

Figure 2, an enlarged view of certain parts, embraf cing a portion of my improvements.

Figure 3 illustrates the top of the main shaft, with my centralizng adjustable guides.

Figure 4 is a plan view, showing the flexible stationary driving-belt for the bobbin-supporters 4.

Figure 5 is a vertical section of parts of the mechanism shown in iig. l.

Figure 6 illustrates a modification of parts, having adjustable arms l, instead of the circular disk 1, shown inthe other iigures.

The nature of my invention consists in the application of adjustable centre-guides on the head of the main-shaft stand, and an arrangement of devices to stop the' machine when a thread breaks, and minor iin-- provements to perfect the cord-making machine.

To enable others skilled in the art to make and use my invention, I will explain certain parts which are not new, and in the claim conne myself to what I deem novel and patentable.

The central shaft E has its appropriate step and bearings. s.

My improvement on this is mainly conlined to its top or head, G.

Fig. 3 shows the top referred to, two plates, g, made adjustable on the flange, by means of a slot and headed screw, h, together with a third, bent in the form of a spring, g', also adjustable, the end of which, in connection' with the terminal points of the other two plates, g, jointly form a central guide, for the passage of the finally-united strands of the cord as it comes from the apex of the central pieces, heretofore in use on the top of the shaft.

Ordinarily, much annoyance is caused by the clamping of the cord when drawn to one side, as is the case when the tension-twist on the pulley or horizontal shaft C is not in a vertical line.

The spring-piece g is designed to yield and permit a knot to pass through, and again resume its position. Jointly, they hold the .cord-to the centre, and prevent a side draught on the loose apical pieces, and greatly aidfin'a uniform delivery of the cord to the reel, and help to make better work.

Fig. 2 illustrates a lever, p, having a hook on the inner end, around or over which the thread from the bobbin passes as it entersv a perforation under the flange of the collar or head that surrounds the bobbin-shafts N. vThis elbowed lever phas its outer end made sufficiently weighty to cause it to drop when the thread breaks which holds it up. A slotted lug contines it by a pivot, shown. Each thread from the bobbins has its own lever p.

In .order to. stop the machine when a thread breaks, each series of bobbins has a drop-rod, K, near the edge of its circular disk or top plate 3, contiguous to the shaft E,

This rod K is sustained by a pin, X, which projects from it, resting on a flange on the upper disk l, there being an opening provided for the pin to pass through.

l When` the rod is turned, by said lever p coming in contact with an adjustable catch It on said1'od,th e pin X is brought opposite the opening, permitting the rod K to drop by its own gravity, and in so doing actuating a lever, clutch,orbeltshipper, by any of the means j now employed for that purpose.

In place of the lever p, I have also tried the bent lever s, shown also by g. 2, which is thrown outward on its being released by the breaking of a thread, and

operating in like manner as the elbowed lever i),for l which I deem it an equivalent.

The three disks 4 which support the'bobbins are pulley-like, and form an equilateral triangle, with the main shaft E in its centre, as in other cases.

The bobbin-shafts have their step below, in the arms projecting from the disk 2, and bearings above in the arms projecting from the disk 1,whivch arms are made adjustable horizontally by means of slots and headed screws.

The bobbin-pulleys or supports are revolved by a stationary exible strap or belt, F, made adjustable by va splice-,fastening at one end, the other end, V f,- being carried back and attached to the side of the machine. By its use a much wider range for adjustment is per* mitted, and, for various reasons, better adapted than a rigid, annular track, with bevelled sides on the inner.

face, for expanding slightly or contracting the action of the pulleys by a vertical adjustment, which dilfers substantially in principle and construction, although in both cases friction imparts motion to the bobbin-supports, so as to revolve them on their own shafts, while they are being revolved by the central shaft in unison.

I may state that in iig. 6, I show a reel, W, formed with radiating arms on one side, each arm provided with a horizontal arm, having raised ends to retain the cord wound upon it. One projecting end is loose, or made to turn out of the way, to facilitate removing the cord.

On the reel-shaft there is a strap-pulley, U, deriving motion from a strap-pulley, u, on the shaft O.

This shaft has a bevelled cog-wheel, V, operated by a screw-gear on a vertical shaft, in its bearings R on the table x.

On the under side is a horizontal cog-wheel, @which meshes in a pinion, P, afiixed to the main shaft E, under its upper bearing. This main shaft hasa iixed and loose pulley, and receives motion by any of the ordinary modes `in general use. This arrangement may possess novelty in its eompaetnessand eieieney, but I do not deem them sufcient to make any claim; l may mention, however, that l employ tension-pins O, shown only in thetop ofthe bobbin-shafts N. These may Vbe inserted at dive s points on the shaft, for the purpose of more eeo ually eonining the threads in position around the shaft as they are drawn out and twisted What I claim as my invention, and desire to seonre by Letters Patent, is-
