SIDNEY F. BEDDIE, OF AMSTERDAM, NEW YORK, ASSIGNOR, 'BY DIRECT AND MESNE ASSIGNMENTS, TO UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A

CORPORATION or ILLINOIS.

FINGER-GUARD FOR SEWING-MACHINES,

Specification of Letters Patent.

Patented Oct. '7, 1919.

To all whom it may concern:

Be it known that I, SIDNEY F. PEDDIE, of"

. Amsterdam, New York, have invented certain new and useful Improvements in Finger-Guards for Sewing-Machines, of which the following is a specification.

This invention relates to improvements 1n finger guards for sewing machines adapted to prevent injury to an operators fingers by the machine needle or needles.

The invention consists in the finger guard shown in its preferred embodiment in the accompanying drawings and will now be hereinafter described and claimed.

In said drawings:

Figure 1 is an elevation of part of a sewing machine having my finger guard applied thereto.

Fig. 2 is a view at right angles to that shown in Fig. 1 with the finger guard thrown part way out of position.

Fig. 3 is a perspective view showing the various parts detached.

Referring now to the details of the drawings by numerals 1 designates my finger guard which is preferably formed of a flat plate with its lower edge inturned as indicated at 2, and is preferably formed with a slot 3 of the shape of an inverted T through which the operator may see the needles. This plate 1 is secured to a plunger 4 which passes upwardly through a collar 5 secured to an arm 6, said arm 6 having a split collar 7 with a set-screw 7 by which the arm may be secured to any desired part of the sewing machine. As illustrated in Fig. 1, the split collar 7 is secured to the presser foot rod 8, but it will be obvious that the split collar 6 may be secured to any desirable part of the machine. The plunger 4 is preferably provided with a collar 10 secured to the plunger by means of a setscrew 11 and a spring 12 is located around the plunger 4 and between the collar 10 and the aforesaid collar 5. This spring 12 therefore tends to normally hold the finger guard 1 in the position shown in full lines in Fi 1. The plunger 4 is provided with a pin 3 which normally rests within a recess 14 (see Fig. 3) in the collar 5, the collar 5 also having two walls 15 and 16 to co-act with the pin 13 and limit the movement of the same as the plunger 4 is moved, as will be hereinafter described. The upper end of the plunger 4 is preferably provided with a knurled head 17 by which the finger guard may be manipulated.

In operation the finger guard is normally in the position shown in full lines in Fig. 1, with the pin 13 of the plunger located in the recess 14 in the collar 5. In this position the finger guard will effectively guard an operators fingers from injury. When it is necessary to give attention to the needles or other parts, the operator merely catches hold of the knurled head -17 and raises it and the plunger 4 so that its pin 13 is out of the recess 14; then the operator rotates the knurled head until the pin 13 strikes against the wall.15 when the operator may release the knurled head and the finger guard will be turned to the position shown in dotted lines in Fig. 1. It will be evident that to return the finger guard to the normal position, it will be necessary for the operatorto merely turn the knurled head 17 until the pin 13 is returned to the recess 14 when the finger guard 1 will be in the position shown in full lines in Fig. 1. If it is desired to move the guard so that it will be thrown only part way back, it may be moved to the osition shown in Fig. 2 when the spring will hold the parts in that position.

It will be obvious that changes and modifications can be made in my finger guard and reference should therefore be made to the appended claims to determine the scope of my invention.

. What I claim as my invention is:

1. A finger guard for sewing machines comprising a vertically disposed rod, a support for the rod intermediate its ends in posed at the upper end thereof, whereby it may be rotated in its support and the finger guard turned out of or into normal position, and means whereby the rod may be yieldingly held with the finger guard in normal position.

3. In a finger guard for sewing machines, the combination of a support, a spring pressed plunger carried in said support, a finger guard connected at the lower end of said plunger, the latter being rotatable in said support whereby the finger guard may be turned out of its normal position, and a stop on said support limiting the rotary movement of said plunger and its finger guard.

4. In a finger guard for sewing machines,

" the combination of a support, a springressed plunger carried in said support, a finger guard connected at the lower end of said plunger, said support having a recess therein, and said plunger having a pin adaptedto normally fit into said recess.

5. In a finger guard for sewing machines the combination of the support including a sleeve, a rod journaled in said sleeve, a collar located on said rod, a finger guard con nected at one side-thereof with the lower end of said rod, a. spring surrounding the 'rod and located'between the sleeve and the collar on the rod and means for limiting the downward movement of the rod through the action of the spring whereby said spring may operate to hold the rod in various set positions.

6. In a finger guard for sewing machines, the combination of a support comprising a collar, a plunger carried in said collar, a collar located on the plunger, a finger guard connected at the lower end of said plunger, and a spring surrounding said plunger and located between the collar on the support and the collar on the plunger, the collar on the support having a recess and the plun and a pin on said plunger coacting with the aforesaid walls on the first mentioned collar and limiting the rotary movement of the plunger.

In testimony whereof I afiix my signature in presence of two witnesses.
