SEWING-MACHINE FINGER-GUARD.

Specification of Letters Patent.

Patented July 20, 1915.

,Application filed June 14, 1910. Serial No. 566,725.

To all whom it may concern:

Be it known that I, MARCUS MASHBIR, a citizen of the United States, and a resident of New York, borough of Brooklyn, county of Kings, and State of New York, have in: vented certain new and useful Improvements in Sewing-Machine Finger-Guards, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a guard adapted to co-act with the resser-foot of a sewing machine to prevent injury to the fingers of the person by the needle of the machine when in operation.

The object of the invention is to provide a finger guard or device for use in conjunction with different constructions of sewing machines wherein one or more needles may be employed and which is adapted to be operatively connected or formed integral with the presser-foot for efliciently preventing the finger of the operatorfrom contacting with the needle or needles of the machine and more particularly when the character of the stitching requires the material being sewed to be guided in various directions in which instances frequent injuries occur by reason of the fingers accidentally slipping under the needle, and a further, object of the invention is to provide a form of device which will permit the quality of the stitching and straightness of the seam to be carefully observed as the work progresses.

Furthermore, my invention consists of certain other novel features and parts as hereinafter described and pointed out in the claim at the end of the description and illustrated in the accompanying drawings forming a part of this specification, in which Figure 1 is a perspective view of one form of the guard embodying my invention. Fig. 2 is a side view of the guard detachably held to the arms of the presser-foot. Fig. 3 is a front elevation of the guard detachably held to the arms of the presser-foot. Fig. 4 is a view of a different arrangement of the guard. Fig. 5 is a view of a form of the guard adapted to be used with a sewing machine wherein two needles are employed.

The presser-foot bar 10 is adapted to be movably held in the head of a sewing machine, as at 11, and to said Presser-foot bar is detachably held the p'resser-foot 12 by the screw 13 passing through the recessed boss 14: formed at one end of the presserfoot 11 and engaging the bar 10, all of which may be of the usual or any preferred construction.

In the machine head 11 is movably held in the usual manner the needle bar 15 carrying the needle 16, and when one needle is used in a sewing machine the presser-foot 12 is provided with a slot, as at 17, and communicating opening through which the needle passes in its reciprocatory movement when the machine is in operation. By slotting the presser-foot lengthwise thereof, as indicated, the spaced arms 18 and 19 are thereby formed, and vertically disposed at the ends of said arms is arranged a fingerguard or device 20. In Fig. 1 the guard 20, consisting mainly of the body 21 and the curved, or semi-circular transverse legs 22 and 23, is formed integral with the presserfoot 12. Between the legs 22 and 23 the peep-opening 2st is provided and through which the character of the stitching and straightness of the seams of the material may be carefully observed by the operator of the machine. This form of guard is provided by the spaced elongated arms or toes 18 and 19 of said resser-foot and angularly bonding said arms or toes substantially centrally of the length thereof so that the guard will be disposed upwardly in front of the needle 16, and by this arrangement an open transverse space 25 is provided above the upper surface of the presser-foot 12 between the body 21 and presser-foot bar 10 for the free movement of the needle 16.

In Figs. 2 and 3 the presser-foot 26 is of the usual form employed in sewing ma chines and has one toe 28 which is longer than the toe 27 and to said, presser-foot is detachably and adjustably held another form of finger guard 29. The body 30 of this guard 29 is similar in form to the body 21 of the guard 20 and has two parallel arranged legs, as 31 and 32, between which is provided the peep-opening 33. The body 30 is vertically disposed preferably upon and adjacent to the free end of the toe 28 for providing an open transverse space 34 between said body and the presser-f0ot bar 10. At the lower end of the leg 31 of the body 30 is formed aboss 35 having an opening 36 for the reception of'the free end of the arm 28 so that the body may be adjusted along said toe, and when adjusted in position said body is rigidly held to the presserfoot 26 by a screw, as at 37. To reinforce this means of connecting the body 30 to said presser-foot a bracket 38 is arranged to extend from the boss 35, and said bracket may be of a shape adapted to rest snugly uponv the upper surface of the toe 28 of the resser-foot. A slot 39 is formed in the bracket 88 and passing through said slot and held in the presser-foot is a screw 40 lfiy which the guard. may be clamped to the cot.

In Fig. 4 is illustrated a presser-foot 41 and aguard 42 formed separate therefrom. Projecting upwardly from said guard is a rod 43 the free end of which, as at 44, is adapted to be movably held in a recess formed in the machine head 45. A spring 46 encircling the rod 43 is interposed be tween the guard 42 and machine head 45 and normally serves to force the guard and said rod downwardly.

A finger guard 47 is shown in Fig. 5 which is adapted to be used in conjunction with a sewing machine wherein may be employed two or more needles for producing a plurality of rows of stitching. In construction the presser-foot 48 is provided with a longitudinally projecting presserplate 49 having openings, as at 50, through which the needles 51, held to the needle bar 52 pass when the machine is operated. At one end of the presser-plate 49 is provided a recessed boss 53 adapted to fit upon the end of the presser-foot bar 10 and is rigidly held thereto by a screw, as at 54, passing through an opening in said boss and held in the presser-foot bar. lhe opposite end of the longitudinal presser-plate 49 is slotted for a part of its length so as to provide a peep-opening 55 between two legs 56 and 57 of a body 58 of the guard. At the lower extremity of the arms 56 and 57 the presserplate is angularly bent so as to position the body 58 vertically upward transversely in front of the needles. Where a plurality of needles are employed in a sewing machine, it is clear, that this form of guard will be of greater width than the guard used with a machine employing only one needle, and the peep-opening 55 will be correspondingly wider. To prevent the fingers of the operator from accidentally passing through said peep-opening a plate of glass, as at 59, 'or other transparent material is held in the guard to close said peep-opening at the same time permitting the work of the stitching to be seen therethrough, and-by thus positioning the guard 47 a transverse space is provided between the body 58 and presserfoot bar 10 so that anynumber of needles which may be used in the sewing machine may have free movement. a

It is understood that changes may be made in the various forms of my guard and in the manner and place of fastening the same to the resser-foot of a sewing machine or in forming the guard integrally therewith without departing from the scope of the invention, therefore I do not wish to be limited to the particular forms of guards herein described and illustrated.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

In a sewing machine finger guard, the combination with the presser-foot bar of a sewing machine, of a presser-foot having one end connected to the bar, said presserfoot having at its free end a vertically disposed integrally formed extension with-an aperture provided therethrough, and a transparent plate secured in the vertical extension across the aperture, whereby the fingers of a person may be protected while vision is unobstructed.
