COMBINATION SPOOL-SUPPORT AND THREAD-GUIDE.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed May 1, 1905. Serial No. 258,179.

To (071 whom. it 77mg concern:

Be it known that I, FRANK BRUEGGEMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented anew and useful Combination Spool- Support and Thread-Guide, of which the following is a specification.

My invention relates particularly to means for insuring the proper paying out of thread from the spool in the operation of sewingmachines; and my primary object is to provide a simple and inexpensive combination spool-support and thread-guide which will effectively accomplish the purpose above suggested.

I am aware that efforts have been made to overcome the objection incident to placing the spool directly upon the ordinary stationary spindle of the sewing-machine; but so far as i am aware the devices heretofore known have failed to accomplish satisfactorily the purposes in view. In this connection it may be stated that silk thread is peculiarly liable to loosen from the spool, especially at the outer layers, so that the coils fall down and become wrapped about the stationary spindle of the machine. causing great annoyance and frequent breakages of the thread, and even where special spool-supports have been provided the difiiculty has not been obviated, owing to the fact that the spool-support when improperly constructed is liable to augment rather than lessen the difficulty.

1 have discovered that by combining with a spool-support at hreadguide having a peculiar relation thereto I am able wholly to overcome the difficulty mentioned, so that the facility of operation of the machine is greatly improved and much loss of time and great annoyance obviated.

My invention is illustrated in the accompanying drawings, in which Figure 1 represents a portion of the arm of a sewing-machine equipped with my combi nation spool-support and thread-guide; Fig. 2, an enlarged broken sectional view of the same; Fig. 8, an elevational view of my device detached from the machine; Fig. L, a plan view of the same, and Fig. 5 a sectional view of a modified form of the device.

Referring to Figs. 1 to 4:, inclusive, A represents the arm of a sewing-machine having the usual spindle a and tensioning device a, B my combination spool-support and threadguide applied to the spindle a, and C a spool applied to the spindle and resting upon the support and provided with thread 0, passing through the guide and thence to the tensioning device.

The deviceBcomprisesasmall bowl 6, which maybe conveniently stamped from sheet metal, and a thread-guide 5, comprising a horizontal base portion 6 and a vertical guide portion Z2 carried thereby. The portion has a struck-up hollow boss 6*, forming a pivot for the bowl, the latter being centrally perforated to receive the pivot. The hollow pivot has its upper end spun over the base of the bowl to prevent separation of the parts. The guide portion 5 which rises substantially from one edge of the bowl, is provided with a vertical slot 5 into which the thread maybe conveniently introduced and in which the thread plays freely as the layers are unwound.

In operation the bowl revolves freely with the spool as the thread is payed out, and by reference to Fig. 2 it will be observed that the lower flange of the spool fits snugly within the spherical inner surface of the bowl, forming such a close joint as to prevent the thread from getting below the lower end of the spool. Moreover, this close joint would be maintained even though the spool should tip somewhat upon its spindle, it being observed that the spindles of various machines vary considerably in diameter. Again, the relation of the guide to the bowl is such as to prevent possibility of the thread getting outside the bowl even where a small-sized bowl is employed.

In Fig. 5, B represents a modified form of the device. In this construction the bowl has a spindle-receiving tube or socket b, constituting an integral portion thereof, which rotates therewith, the lower end of the tube extending below thebowl and journaled in the base of the thread-guide.

Other modifications in which a thread-guide occupying substantially the same relative position at an edge of thebowl may be used without departure from my invention.

What I regard as new, and desire to secure by Letters Patent, is

1. Acombination spool-support and threadguide, comprising a bowl. and a thread-guide having a base upon which the bowl is journaled and a vertical guide portion at one edge of the bowl with a channel for the thread, the

thread-guide base and the bowl having a spin- 1 portion at one edge of the bowl provided with die-receiving passage, substantially as and for a vertical guide-slot in which the thread may I the purpose set forth. play as it is payed out, for the purpose set 2. Acombination spool-support and threadforth. 5 guide, comprising a bowl, and a thread-guide FRANK BRUEGGEMAN.

having a base portion rotatably secured to the ln presence ofe bowl by a tubular pivot through Which a spin- L. HEISLAR,
