THREAD-GUARD FOR CAP SPINNING AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 359,007, dated March 8,1887.

(No model.)

To (ZZZ whom it may concern.-

Be it known that LLEEDHAM BINNS,0f Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Thread-Guards for Cap Spinning and Twisting Machines, of which the following is a full, clear, and exact description.

This invention relates to the guards used in cap spinning and twisting frames to prevent the several yarns from interfering or entangling with each other when being spun and twisted.

The invention consists in a novel construc tion of the guards, of partly circular form at their backs and of a peculiar shape at their front edges; also, in a combination of the guards, made to interlock with one another at their front edges, and the back board, top board, and caps and spindles of the frame or machine,substantiallyashereinafterdescribed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a mainly sectional side view only of so much of a cap spinning and twisting frame as is necessary to illustrate my invention, the same showing but asingle spindle and cap with parts immediately pertaining thereto and with my improved guard applied. Fig. ,2 is a partially-sectional plan view showing the back board of the machine and a pair of my improved guards applied to a couple of caps and their spindles. Fig. 3 is a front elevation of one of the guards detached.

A indicates the back board of a cap spinning and twisting frame or machine, and B the usual top board thereof.

O is one of the top rollers, and D one of the bottom rollers, between which and down through an eye in the top board each yarn 1) passes to its respective spindle c, or bobbin d thereon.

E is the spindle-cap; e the whirl by which the whirl-tube 0 is rotated upon the fixed spindle c. f is the traversingrail, and g the foot or spindle rail, all as in other cap spinning and twisting frames.

G G are the guards between the caps E. These guards run up to the under side of the top board, B, and extend to the bottom of or a little below the caps, or thereabout, as usual. Said guards, which may be made out of sheet metal, are bent or shaped so that they assume in horizontal or transverse section a partlycircular form, corresponding to or approximating a half-circle, concave on their inside at their backs h,- and in some cases I make their tops of a partial bell or dome shape, thereby entirely dispensing with all angular nooks and corners, and allowing the yarn to travel perfectly at ease and so that as it is rotated it will only once at each revolution strike the guard or guards on what may be called the going-on side-that is, on the left or right hand side, accordingly as the yarn is being spun or being twisted or doubledinstead of striking on the sides of adjacent guards and inner surface of the back board. This reduction in the striking of the yarn enables the latter to be twisted more perfectly and steadier,

and the yarn coming in contact with the interior curved surface of the guard has its outside fibers rolled onto it instead of being battered, thereby causing less waste and making a smoother or polished yarn. No awkward corners or angular spaces are left within the guards or between them and the back board or top board for the collection of hairs, fuzz, or waste; but the guards maybe quickly wiped out by rubbing a cloth up and down within them, if necessary, at distant periods of time, to remove any such material as may be left there, instead of having to frequently pick it out of angular spaces between the guards, back board, and top board. This will greatly economize labor and there will be less waste.

The guards G may be fastened to the back board,A,by a single row of screws, .9, arranged centrally down the back of them. Their forward vertical edges, which stand out in front 011 opposite sides of the cap, are constructed so that the one edge, It, is plain and straight, while the other edge, Z, is turned over to form a lap or pocket for the plain straight edge 70 of the next guard to engage and iit within, after the fashion of a tongue-and-groove joint. This construction provides for the several guards throughout the whole row of spindles, or for any number of them, supporting one another in front, thus making them solid or substantial in front as well as at their backs, instead of, as in the case of the ordinary double guards,

depending upon wings to hold them at their backs and leaving them loose or free in front, and consequently liable to get out of position.

2. The combination, in a cap spinning and twisting frame, of a series of guards, G, having curved backs continuous with their sides and Having thus described my invent-ion, what I made t-ointerlock with one another by tongueelaim as new, and desire to secure by Letters and-groove joint down their front edges, the

Patent, is

1. The within-described guard for cap spinback board, A, to which said guards are secured in their rear, the top board, 13, the caps nin and twistin frames of part] circular E and s indles c essentially as described.

#3 b 1 i y 2 V i construction at its back h,and having a straight front edge, is, on one side and a turned-over front edge, Z, on its opposite side, substantially as specified.
