GUARD FOR SEWIN G-MACHIN' E TAKE-UPS.

Specification of Letters Patent.

PatentedJuly 11,1916.

Application filed February 26, 1915. Serial No. 10,744.

To all whom it may concern:

Be it known that I, ALFRED L. MAorsoN, a citizen of the United States of America, residing in the city of New. York, county and State of New York, have invented a certain new and Improved Guard for Sewing- Machine Take-Ups, of which the following is a specification.

My present invention relates more particularly to a special improvement in the Willcox and Gibbs high-speed sewing machine withrotary take-up forming the subject of the Letters Patent of Borton, No. 572,090, dated November 24, 1896, and Brush and Horton, No. 675,438, dated June 4, 1901. In the said machine there is attached to the left hand end of the rotary shaft in the head of the machine a take-up in the form of a wheel, which, as shown in Patent No.

675,438, has to be made with openings in it for lightness,'because of the high speed at which the machine is run, -say 3000 stitches a minute.

The object of my invention is to provide this rotary take-up with guard means to prevent the operator fromaccidentally getting her fingers or hair caught in the wheel, whileat the same time not interfering with the easy threading of the take-up or other part of the machine orthe removal of a broken thread from the take-up, and this without removing the guard from its normal position. t

In the accompanying drawing, Figure 1 is an. elevation of the left-hand end of the machine head, provided with the preferred form of improvement; Fig. 2 is a side view. of my improved guard and the supporting band, detached from the machine; Fig. 3 is a corresponding view of the other side of the same guard and band; and Fig. 4'is an enlarged view of the left hand end of the machine with -the take-up, its band and the guard in sect-ion.

A is the sewing machine head, which in rings and central areas united by r'adial arms X, the spaces 13 between which form thread ends.

openings into which the operators fingers may accidentally be inserted or stray locks of hair find their way and become entangled 1n the rapidly driven mechanism. The two disks are united by a screw 14 passing through a distance thimble 15 (Fig. 4) and tially the same as heretofore used and as disclosed'in the tioned.

Over the otherwise open faceor end of the rotary take-up I provide a guard in the form of a disk D, which I secure in a fixed patents hereinabove menpo sition by suitable means, as a pair of lugs I.

20, 20, at its lower rear edge, attached by screws or Otherwise to the band E. By the described mode of attachment, a clearance 21 (Figs. 2 and 4) is left between the disk 20, '20, for the free introduction and play of the thread in the take-up and for the proper threading of the needle N. This guard disk D is provided with. a central opening 22 opposite a central opening 23 in the outer disk of the take-up (Fig. 4) in order. to permit the operator to pick out broken Neither the presence of this central opening 22 nor the clearance 21 will interfere with the performance of the function of the disk D guarding against the catching of the operatorsfingers or hair in the rapidly revolving take-up.

I claim as my invention: i a

1. In a sewing-machine, a rotary take-up having an exposed spider disk with central opening, in combinationv with a fixed guard disk mounted over the open end of the takeup and having a closed area coextensive with the open frame area of the spider disk to prevent accidental contact with the spider arms but having a central opening registering with the central Opening Ofthe spider disk through which thread ends may be picked up.

D and band E, all the way around except at 2; In a sewing machine, a rotary take-up having an inner and an outer spider disk spaced apart but secured together, the outer spider disk having a central opening while the inner disk has a central closed diaphragm, in combination with a fixed guard disk mounted beyond the exposed face of the take-up 'and having a closed area coextensive with the open frame area of the spider disks to prevent accidental contact with the spider arms and having a central opening registering with the central opening of the outer spider disk through which thread ends may be picked up.

3. In a sewing machine, a rotary take-up having an exposed spider disk with sur-
