GUARD AND THREAD-CONTAINER FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed August 6, 1914. Serial No. 855,400.

To all whom it may concern:

Be it known that I, MORRIS TArLITsxY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Guards and Thread-Containers for Sewing-lvlachines, of which the following is a specification.

This invention relates to sewing machines used in garment factories, a number of machines being usually arranged in a row on an elongated bench or table, each machine being equipped with a bobbin winder, such as that employed in the Wheeler and "Wilson machine, to wind the shuttle thread on the bobbin while the bobbin is removed from the shuttle.

The invention has for its object to provide an attachment adapted to hold the supply spools on which the needle and shuttle threads are stored, in close proximity to the machine and to the bobbin winder, and to deliver the threads to the stitch-forming mechanism and to the bobbin winder without liability of entangling or obstructing either thread in its passage from the spool on which it is stored.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification: Figure 1 represents a plan view showing two sewing machines each equipped with an attachment embodying my invention; Fig. 2 represents a section on line 2-2 of Fig. 1, and a. side elevation of the sewing machine equipped with the attachment; Fig. 3 represents a section on line 3-3 of Fig. 1; Fig. 4 represents a side view of the attachment; Fig. 5 represents a top plan view of a portion of the attachment.

In the drawings, 12 represents the head of a sewing machine, which may be of the well known lVheeler and \Vilson type, and is equipped with a bobbin winder 13 adapted to detachably engage and rotate the bobbin 13 which is removable from the bobbin winder for application to the usual shuttle of the machine, not shown.

14: represents a box adapted to inclose the two spools l5 and 16 on which are stored respectively the shuttle thread 17 and needle thread 18. The box is adapted to be attached to the sewing machine bench or table 19 at one end of the head 12 and is open at one side to permit the convenient insertion and removal of the spools, the bottom of the box being preferably provided with pins 20 to enter the bores of the spools. The open side of the box is preferably provided with a hinged door 21. The top of the box is provided with. small orifices 22 forming outlets for the

threads

17 and 18, and with narrow slots 23 extending from said outlets to the edge of the top at the open side of the box, said slots enabling the threads to be conveniently located in the thread outlets 22 by moving thev threads laterally through the slots to the thread outlets.

The top of the box is provided with a thread eye or guide 25 through which the shuttle thread 17 passes on its way to the bobbin 13*, and with a thread eye or guide 26 through which the needle thread 18 passes on its way to the needle 27.

lhe box is attached to the bench or table with one of its sides in close proximity to the driven pulley 28, which is rotated by the usual belt 29 and rotates the shaft through which the needle bar 30 is recipro cated. Another side of the box is in close proximity to the shaft of the bobbin winder 13.

To the side of the box which faces the pulley 28 is attached a sheet metal guard 31 which overhangs the pulley 28 and the usual hand or fiy wheel 32, said guard being above 7 the said pulley and hand wheel and below the portion of the needle thread passing from the guide 26 to the needle.

It will now be seen that the box 14: located as described relatively to the sewing machine and bobbin winder holds the supply spools in close proximity to the machine head and to the bobbin winder, the guard 31 preventing any possibility of the needle thread being entangled with the pulley 28 and the hand wheel 32. By reference to Fig. 3 it will be seen that the thread guide 25 is in close proximity to the bobbin winder so that the short stretch of thread intervening between the guide 25 and the bobbin is not liable to be entangled or obstructed in its passage.

The guard 31, which is preferably inclined as shown by Fig. l, may have an extension 31 shown by dotted lines in Fig. 1, said extension covering the rear stretch of the driving belt 29, extending between the pulley 28 and the point Where it passes through or below the table.

Having described my invention, I claim:

1. A thread protecting and supplying attachment for sewing machines, comprising a boX adapted to inclose the supply spools on which the needle and shuttle threads are stored, said box having an open side for the insertion and removal of said spools, thread outlets in its top, and thread guides above the top, one arranged to guide the needle thread across the driven pulley and hand wheel of the machine, and the other arranged to guide the shuttle thread to the bobbin winder or" the machine, and a guard attached to one side of the box and formed to overhang the said driven pulley and hand wheel and prevent the needle thread from fouling therewith.

2. A thread protecting and supplying attachment for sewing machines, comprising a boX adapted to inclose the supply spools on which the needle and shuttle threads are stored, said box having an open side for the insertion and removal of said spools, thread outlets in its top, narrow slots leading from one edge of the top to said outlets, whereby the leading ends of the needle and shuttle threads may be quickly guided to said out lets, and thread guides above the top, one arranged to guide the needle thread across the driven pulley and hand wheel of the inachine, and the other arranged to guide the shuttle thread to the bobbin winder of the l machine, and a guard attached to one side of the box and formed to overhang the said driven pulley and hand wheel and prevent the needle thread from fouling therewith.

In testimony whereof l have aflixed my signature, in presence two witnesses.
