Renewed June 3, 1939 3 Claims.

Thisk invention relates to a sewing machine guard, the general4 object of the invention being to provide a casing for enclosing portions of the wheel and belt of the sewing machine as well as the drive for the bobbin winding means, with a .door1 in the casing for providing Aaccess to the interior of the casing so as to enable the belt to be put on the pulley or removed therefrom and to permit access to other parts enclosed by the casmg.

The present invention is an improvement on that forming the subject matter of an application filed by me on July 7, 1937, Serial No. 152,448.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a front view showing the invention in position on a sewing machine and with parts of the casing broken away to show the screw for fastening the casing to a part of the machine.

Figure 2 is a perspective View of the casing looking toward the front or outer side thereof.

Figure 3 is a view of the outer side of the casing with the door in open position.

Figure 4 is a section on the line 4-4 of Figure 2.

Figure 5 is a section on the line 5-5 of Figure 2.

In this drawing, the letter A indicates the casing which is composed of the inner side wall I, the outer side wall 2, the rear wall 3, and the front wall 4. The casing has a low part at its front end and the upper edge of the inner side wall I at an intermediate point curved upwardly and rearwardly to the inner edge oi the rear wall 3 as shown at I' and the outer side wall 2 has its major portion terminating in a door covered opening 5 through the lower portion of this side wall 2 extends to the rear wall 3 under said opening as shown at 2. A door 9 isl hinged at I0 to the wall 3 and has connected to the upper lpart which includes a top portion having its front part curving in an upwardly extending bow and from the kcurved part the strip extends downwardly and rearwardly to a point adjacent the outer portion of the top edge of the rear wall 3 when the door is closed. From the front end of 55h the bow the strip extends downwardly substantially vertically where it comes adjacent the rear part of the top edge of the front portion of the side wall 2 -with the front edge of the strip substantially flush with the outer side of said side wall 2 when the door is closed. The iront wall 4 5 is extended 'over the top edges of the low front portions of the two sidewalls I and 2 with the rear end of the extended portion provided with a recess 'I which is spaced from the outer edge of said extended portion as shown in Figure 4. The 10 outer portion of this rearend of the extension of the front wall 4 comes adjacent the lower end of the vertical part of the strip 6, when the door is closed, as shown in Figure 2. The rear edge A of the front part of the side wall 2 and the top 15 edge of the part 2 of this side wall are formed with the inwardly offset anges 8, as shown in Figures 3 and 5 for forming stops for the door 9, the door being provided with a suitable latch II and in its upper part the door is provided with 20 an opening I2 for the passage of the member I3 of the belt pulley I4 of the wheel I5 ofthe sewing machine, as shown in Figure 1. This opening must be made large enough to permit the door to swing open and close without interference 25 from the member I3. The strip 6 is narrow enough to permit -the passage of the upper portion of the wheel I5 as shown in Figure l and the recess 1 permits passage of the periphery of the wheel. A hole I6 is formed in the lower por- 30 tion of the inner side wall I for the passage of a screw I'I which fastens the casing to a part of the machine as shown in Figure 1 and a rectangular opening I8 is formed in the front lower portion of the wall 2 to permit the passage of 35 the bobbin winding means shown in dotted lines at I9 in Figure 1.

Thus it will be seen that the casing is held in place by the screw II, which is accessible through the door opening when the door is open and that 40 the casing covers the upper portion of the belt 20 of the sewing machine, the major portion of the wheel I5 and also covers the pulley I4 as well as the bobbin winding means so that there is no danger of the operator of the machine being in- 45 jured by such moving parts of the sewing machine or having his clothing caught in said parts and the casing will also protect the cloth being sewn upon as it will prevent the cloth and the garment of the operator from being soiled with 50 grease or the like thrown off by the movable parts of the machine or by contacting such parts. However, the parts are readily accessible by opening the door so that the belt can be placed over the pulley or removed therefrom and the parts oiled or otherwise attended to. By exposing the upper portion of the wheel l5 this portion can be engaged by a hand of the operator, to turn the same in the usual manner but the strip 6 will tend to prevent the fingers of the operator from being injured by the wheel as only the rim of the wheel projects above this strip.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within thejscope of the appended claims.

Having described the invention, what is claimed as new is:

1. A guard for a sewing machine comprising a casing including inner and outer side walls, a rear wall, said side walls having low front portions, a combined front and top wall connecting the front and top edges of the said low front portions togethenfsaid outer side wall having a door opening in its rear portion and the rear end of the top wall terminating at said opening, a door for closing the opening and extending above the same when the door is closed, and a narrow strip connected with the top portion of the door and projecting toward lthe inner wall and having a portion extending over the top of the same and a portion extending partly down the front of the same, said strip being narrower than the width of the casing to permit a portion of the wheel of the sewing machine to slightly project above the same, means for connecting the rear wall to a part of the machine.

2. A guard for a sewing machine comprising a casing including inner and outer side walls, a rear wall, said side walls having low front portions, a combined front and top wall connecting the front and top edges of the said low front portions together, said outer side wall having a door opening in its rear portion and the rear end of the top wall terminating at said opening, a door for closing the opening and extending above the same when the door is closed, and a narrow strip connected with the top portion of the door and projecting toward the inner wal] and having a portion extending over the top of the same and a portion extending partly down the front of the same, said strip being narrower than the width of the casing to permit a portion of the wheel of the sewing machine to slightly project above the same, Vmeans for connecting the rear wall to a part of the machine, the upper portion of the door having an opening therein for passage of a part of the wheelof the machine and the lower portion of the outerside wall having an opening therein for passage of part of the bobbin winding means of the machine. Y

3. A guard for a sewing machine comprising a casing including inner and outer side walls, a rear wall, affront wall and atop wall, said top wall having an opening therein for the passage of a part of the wheel of the machine, means for connectu ing the inner wall toa part of the machine, the outer wall having an opening therein, and a door for closing the opening.
