BOBBIN-HOLDER FOR SPOOLING'MACHINES..

SPECIFICATION forming part of Letters Patent No. 558,893, dated April 21, 1896. Application filed March 7, 1895. Serial No. 540,817. (No model.)

To aZZ whom it may concern.-

Be it known that I, STEPHEN N. BOURNE, of Manchester, county of Hillsborough, State of New Hampshire, have invented an Improvement in BobbinJ-Iolders for Spooling- Machines, of which the following description, in connection with the accompanying drawin gs, is a specification, like letters and numerals on the drawings representing like parts.

Bobbin-holders are designed to support a bobbin in such manner that the yarn is delivered therefrom with the most nearly uniform and least possible strain.

lleretofore it has been customary to provide bobbin-holders with one or with a pair of guards, one of which guards is used to produce tension on the yarn or thread to be wound, the said yarn or thread passing from the bobbin laterally in a substantially horizontal plane to and about the guard and thence vertically, or nearly so, to the usual spooler-guide. In the use of bobbins of very large diameter, which are now being made, these usual holders fail to act properly and the yarn or thread is frequently broken, due to excessive strains, and hence I have produced a bobbin-holder wherein the strain 011 the yarn is reduced to the minimum, the yarn or thread leaving the bobbin in a substantiallyvertical path and passing to the spoolerguide, the said yarn or thread being drawn from the bobbin without any perceptible friction or strain, the bobbin-holder being provided with a wire guard, which acts to steady the bobbin as the thread oryarn is drawn therefrom.

Figure l in side elevation represents a bobbin-holder embodying my invention, a bob bin being shown therein in dotted lines; and Fig. 2 is an outer end elevation thereof.

The bobbin-holder herein shown consists of a concave plate or support a open at its ends and extended upwardly along one side to form a curved retaining-wall a at one side of the holder. The bobbin rests at its side on the support (6 and is rotated thereon while in nearly horizontal position, the wall a, connected with the support a, aiding in preventing the escape of the bobbin as the latter rotates from the support. By means of an car a projecting from the under side of the support it is secured, as by a bolt 2, to a stand I), transversely recessed or grooved at Z) to receive a suitable supporting rod or bar b a set-screw 5, extended through one of the walls of the groove, bearing against said bar and securing the holder rigidly thereto.

The stand Z) is upturned across the inner end of the support a, as at N, and is preferably laterally enlarged or widened,as shown in Fig. 2, to form a stop for the adjacent end of the bobbin, which rests easily in the support a. The back 11 of the stand is extended forward at 5 thus forming a finger above the wall a of the support, its inner edge I) forming one side of a thread guide or slot 0 in a vertical plane passing through the longitudinal axis of the bobbin-holder, as clearly shown in Fig. 2.

The support a has secured to it by a screw 10 one end of a bar cl, which I shall denominate a guide-bar, the other end of the bar being secured by a screw 12 to the back plate 12 said guide-bar presenting a straight, but somewhat rounded, surface directly above the bobbin and substantially parallel to its axis, the bar constituting the active side of the slot 0, the thread at times touching it.

A guard e, preferably formed of stiif wire bent into suitable shape and concaved between its upper and lower edges, is shown as mounted in ears d on the bar d to move laterally and close the open side of the bobbinholder and prevent the bobbin from flying out, outward movement of the guard being limited by a stop or enlargement (i on the outer end (1 of the bar and in the path of the outer end of the guard, the lower edge of the latter being located a short distance above the open side of the support a. r

The thread or yarn tas it is drawn off from the bobbin B passes directly and substantially vertically to the spooler-guide 11 through the slot or thread-guide c, in which it is free to move as unwound, with the least possible friction. As the thread moves from one to the other end of the bobbin, the latter is apt to be jerked or thrown about in the holder sufficiently to break or strain the thread, and this is prevented by the guard e, which rests against the side of the bobbin and steadies it without offering any opposition to its free rotation other than that due to the weight of the guard as it is held by gravity against the bobbin side.

The bobbin is inclosed within a substantially cylindrical space of sufficient size to allow the necessaryfrce rotation of the bobbin as it is unwound.

My invention is not restricted to the specific construction and arrangement herein shown, as the same may be modified or changed in various details without departing from the spirit and scope of my invention.

I claii 1. A bobbin-holdercom posed of an inclined curved plate a, having at one side an up wardly and inwardly curved wall" a, a stand 17, to which the said plate is connected, said stand having an upturned end N, a bar (Z connected at one end to said upturned end and its other end to said curved plate, and a swinging guard 6 supported from said bar, one side of the said bar lying parallel to and substantially vertically above the axis of the bobbin, substantially as described.

2. A bobbin-holdercomposed of an inclined curved plate a, having 'at one side an upwardly and inwardly curved wall a, a stand I), to which the said plate is connected, said stand having an upturned end 11 and a forward extension W, a bar (Z connected at one end to said upturned end and its other end to said curved plate, and a swinging guard 6 supported from said bar, one side of the said bar lying parallel to and substantially vertically above the axis of the bobbin, substantially as described.

3. A bobbin-holder comprising an inclined curved plate on which the bobbin may lie and rotate, said plate having an upwardly-directed extension to constitute one side of the holder, a connected guide-bar for the thread located above and substantially parallel with the axis of the bobbin and provided with a stop, a depending guard pivotally connected to said frame and adapted to rest by gravity against one side of the bobbin, the outward movement of said guard being limited by said stop and a finger lying substantially above the bobbin with its edge opposed to the said guide-bar, thus leaving a slot above the axis of the bobbin for the travel of the thread vertically from the bobbin, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

STEPHEN N. BOURNE.
