SPECIFICATION forming part of Letters Patent No. 378,376. dated February 21, 1888.

Application filed November 2, 1357. Serial No. 254,055. (No model.)

To aZZ whom, it may concern.-

Be it known that I, PATRICK Rooney, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Weavers Courts. of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The object of my invention is to produce a more convenient and durable comb for the use of weavers than has heretofore been made.

The weavers combs now commonly used consist of a number of fine'pointed springwire teeth all rigidly fastened in a metal back. In using the comb a weaver frequently has occasion to pick up a single thread, and for doing this it is necessary that the point of one ofthe teeth of the comb should be separated from the rest of the teeth, and this has usually been done by bending the endinosttooth of the comb away from the others, so that its point may be used to pick up the thread without interfcn ence from the other teeth. This frequent bending of one of the teeth back and forth soon in or it is soon broken chi, and one after another of the teeth will thus be broken, until finally the comb becomes worthless. This defect in the combs as now made is removed by the present invention, which consists in making the endmost tooth of the comb movable, the shank of the said tooth being preferably thickened to stiffen and strengthen it, and the said tooth being preferably pivoted in the back or frame of the comb, so that it can be turned away from or up to the side of the remaining teeth, according as it is to be used separately as a single point or in conjunction with the remainder of the teeth of the comb.

Figure 1 is a side elevation of a weavors comb embodying this invention; and Fig. 2, an enlarged section on line a: "1 Fig. 1, showing the connection of the movable tooth with the back or frame of the comb.

The main portion of the comb, consisting of the teeth a and the back or frame b, may be of usual construction, the said teeth being composed of pointed spring wires or needles rigidly fastened in the back I), which may be a strip of metal folded, as shown in Fig. 2, to form a channel, in which channel the wires or teeth a are rigidly fastened by solder.

In order to provide for the use of one of the teeth independently of the others without bending one of the rigidly-fixed teeth a, as has been heretofore practiced, the. comb is, in ac cordance with this invention, provided with a movable tooth, 0, shown as havin a stiffened shank, c, and an enlarged base, 6, that enters the channel or tooth-holding groove or recess in the back I) of the comb.

It is generally most convenient to have the tooth c pivotally connected with the back or frame Z), which may be effected by providing the base 0. of the tooth with a hole, 0, and striking up or indenting the side of the frame I), as shown at b, to engage the shank of the tooth cin the said hole'c, as shown, thus fast ening the said tooth in the back, but permitting it to have a pivotal movement therein, as indicated by the full and dotted line positions shown in Fig. 1. Thus, when the comb is to be used for scraping a surface,the tooth 0 will be turned up beside the other teeth, as shown in dotted lines, Fig. 1; but when a single point is required the tooth 0 maybe turned away from the others without bending or straining it, as shown in full lines, Fig. l.

The shank ofthetoot'n c is preferably slightly bent, as shown, to cause it-to more readily err gage and pick up a thread when required.

I claim- 1. As an improved article of manufacture, a wcavers comb havinga series of rigidly-fastened teeth and a movable tooth, substantially as and for the purpose described.

2. The combination of the back or frame, with a series of teeth rigidly fastened therein, and a tooth pivotally connected with the said frame, with its point movable toward or from the other teeth, substantially as described.

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