ALPHA H. WRIGHT, OF'ALBANY, NEW YORK, A SSIGNOR TO FREDERICK OSANN COMPANY, A CORPORATION OF NEW YORK.

SEWING-MACHINE SHIELD.

Specification of Letters Iatent.

Patented nee-i7, role.

Application filed September 25, 1917. Serial No. 193,185. I 1

To all whom it may concern: I

Be it known that I, ALPHA H. WRIGHT, a citizen of the United States, residing at Albany, county of Albany, State of New York, have invented Improvements in Sewing-Machine Shields, of which the following is a specification, reference being had to the accompanying drawings, thereof.

This invention has. reference to improvements attached or adapted to be attached to the heads of sewing machines to protect the operator particularly the operators eyes from flying particles of needles brokenduring the operation of the machine.

One object of the invention is to provide a shield of the nature described adapted to be readily attached to the head of a sewing machine to protect the operator without obstructing the operators view of the work or his or her manipulation of parts of the work, as in sewing on buttons.

Another object of the invention is to provide a shield of the nature described which, when mounted on a machine, can be swung or adjusted as desired by the operator.

Other objects of the invention will appear from the following description.

The invention consists in such novel features of construction and combination of parts as-shall hereinafter be more fully described and pointed out in the claim.

Figure 1, represents a view of the improved shield attached to the head of a sewing machine of well known construction, parts of the sewing machine being omitted as they form 110 part of the present invention.

Fig. 2, represents a view substantially at right angles with Fi 1. I

Fig. 3, represents a p an view of the improved shield.

Similar characters of reference designate corresponding parts throughout.

As shown in the drawings A and B represent respectively portions of the head and work plate of a sewing machine of. any well known construction provided with the usual stitch forming devices including the needle forming part I apparent.

C. In order to more clearly point out the advantages of the present invention I have preferred to illustrate the same in combina tion with a sewing machine having a button clamp or other work holder of ordinary construction, parts of which are shown at D, ready access to which is desirable at all times for inspection and for adjustment of parts of the work holder or of some part of the work .in said holder.

The improved shield comprises the supporting bracket 5 adapted to be secured to the head -A of the sewing machine and having, pivotally connected with said bracket, the arm 6 which has the section or member 7 mounted to swing relative to the axis of said arm and to be secured in the adjusted position means of the screw nut 8. At

the outer portion of member 7 is the clamp or socket 9 into which is received and retained the upper edge portion of the shield 10 of glass or other transparent material.

The uses of the improved shield will be In sewing machines and particu larly in power driven button sewing and similar machines the stitch forming means are operated at great speed and extreme nicety of adjustment of the buttons or other parts of the work is necessary in order that the needle should not strike the same and be broken. The button or button holder should therefore be in View of the operator-in order to avoid such breakage by adjustment of the "button before the stitching operation. Notwithstanding the feareful adjustment of the'work and the needle it is found that breakage of needles often occurs with the result that parts of the broken needles fly with considerable force toward the operator.

By the use of this device the operators face is needles or bu-ttons without obstructing his or her view'of the workv and without obstructing his or her access tothe work below the lower edge of the shield 10. It is also to be noticed that this-shield may be swung away from its normal position and can be adjusted as to its angle of inclination.

Having thus described my invention 1 clalm as new and desire to secure by Letters Patent.

A shield apparatus comprising a bracket adapted to be secured to the head of a sewing machine to extend laterally thereof, an arm pivoted to said bracket to extend transvei'sely of said head, said arm having a pair of clamping plates one 0i WhlCll 1s rotatably adjustable on said arm, and a 10 glass shield having 1ts upper edge clamped between said plates.
