SEWING-MACHINE GUARD.

Applicationfiled July 15, 1925. -Seria1,,N'o.i43,823.

To alt err/10m t'twmy concern:

Be it known that We, HARRY \VEINT'RAUB and learn SnrrMAN, citizenscof the United States, residing at New York city, in the county of New York and State of New "York, have invented-cert ain new and useful improvements inSewing-llfaChine Guards, of which the following is a'specification.

This invention relates to protecting devices for sewing niachinesandthe like and more particularly to a novel andimproved guard attachable to the frame of a sewing machine to avoid injuries to the operator.

One of the -objects of our invention is to provide a sewing machine guard or pro,- tector for the transmitter shaft, pulley wheels, motor andvother mechanism ofthe machine, which mechanism cannot be operated when the said guard islowered,thus making-it necessary that the operator position the said-guard andthus protect himself against injuries.

A further object of=our invention is to provide aniachineattachment adaptedto be installed and positioned on a sewing 1nachine frame, the transmitter shaft,pnlleys, motor and'the {foot treadle, said-guard being constructed and arranged to prevent the clothing of-the operator" or any part. of his person from-comingiin contactand being injured bythe operating mechanism.

To enable others skilled in the .art to fully comprehend the underlying features of our invention, that-they'mayembodythe same in the various alterations instructure and relation contemplated, drawings-. depicting a preferred form have been annexedias a part of this disclosure and in such drawings, similar reference charactersjdenote corresponding parts throughout all the views, of which,

Figure 1 is a view, showing the application of our invention, the guard being down, rendering the machine operating mechanism inoperative.

Figure 2 is a similar view showing the guard when positioned to protect the operator from injury.

Figure 3 is a perspective view, showing the guard detached from the frame.

Figure 4 is an end View.

Figure 5 is a detailed view of a supporting bracket or adapter.

Referring now to the drawings, wherein like reference characters designate corresponding parts throughout the several fram between 1 the. front supporting legs 6,

above referred to. Attached to the skirt board brackets 11 we rovide two end adapters, in the form 0 roasting 12, having lugs 13, 14, wherebythey may be fastened tovthe brackets :11, above referred to.

The saidadapters support top andbottom,

horizontally extending, iron rods 1.5 116,130- sition-ed forwardly of thertransmitter shaft 8 of thesewing machine. In actual practice, we lind'that thelower; rod =ldshonld be about seven and one-half inchesfrom the floor or base of the supporting legs 6. vThe lower rod 16 is in the formof areenforcing rod, which stabilizes theadapters and the supporting shields, further to be ,described. Thesaicbtop andibottom rods 15,

1.6,.may be attaclied-tozt-he end ,andinner sidesof the adapters many .well known.

manner and with, the said shields constitute a unit that,mayibepositioned at theifront ,of any conventional, type of sewing machine frame where it may be required.

. Referring particularlyto'Figures -1.to 3 inclusive, it will be observed that ithe top rod l e-supports the shield 17 ,-which is'substantially rectangular inshape, jbeingrolled or curvedcslightly at a point just above the center to permit the operator to sit comfortably at the machine and allow freedom of the knees. The shield 17 is preferably constructed of galvanized sheet metal, having a rolled, top edge 18 and rolled side edges 19. The bottom roller edge 20- is loosely mounted on the shaft 15, so that the shield may be moved from the position shown by Figure 2 to the position shown by Figure 1 so as to cover the foot pedal 10. hen the shield 17 is down, it will be readily understood that the operator cannot actuate the foot treadle 10- and before doing so, must raise the shield to the position shown by Figure 2 and lock or latch it with the hook 21 which passes through an eye as shown.

To the right of the shield 17 and spaced therefrom so as to permit the free operation of the rod or link 9, we provide a second shield or guard designated in its entirety by numeral 22. The guard 22 is also constructed of galvanized sheet metal, the lower portion 23 of which is provided with a bottom rolled edge 24, whereby it may be mounted on the upper rod 15 in the same manner as the shield 17 The said guard 22 is provided with a slightly, bent wall 25, formed integral with the top 26, said top, being, of course provided with the usual hook and eye arrangement, whereby it may be fastened to the frame proper. The material of the front wall is bent inwardly to provide flanges 27, 28, thus shielding the motor and other operating mechanisms connected to the machine head.

It will be readily appreciated that by providing a guard and rotector of this character wherein the so-iid shield is positioned between the transmitter shaft and the foot treadle, that the danger from the mechanism, when in operation, is eliminated and thus accidents are reduced to a minimum. Of course, when it is required to gain access to the transmitter shaft, pulleys or motor, the shield may be lowered to the position as shown by Figure 1, but it will be readily understood that the shield must be again raised and attached before the operator can operate the treadle that controls the operating mechanism of the machine head.

While we have illustrated and described our invention with some degree of particularity, we realize that in practice various alterations therein may be made. WVe therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without depar ing from the spirit of the invention or the scope of the appended claims.

Having thus described" our invention, what we claim as new and desire to secure by United States Letters Patent is 1. A machine guard of the class described comprising a shield, a supporting rod,'means for connecting the shield to the rod whereby it may be'lowered to render a machine foot pedal inoperative and means for supporting said rod to the front of a machine frame.

2. A machine guard of the class described comprising a shield, a supporting rod, means for attaching the shield to the rod whereby it may be lowered to render a machine foot pedal inoperative and means for supporting said rod to the front of a machine frame forwardly of the transmission shaft of said frame.

3. A machine guard of the class described comprising a rod, a shield attached to said rod, means for attaching said shield to said rod forwardly of the transmission shaft and power operating mechanism of a machine, said shield being movable to a position whereby the foot pedal is rendered inoperative and means connected to the ends of said rod for attaching the same to the front of a machine frame.

4. A machine guard of the class described comprising a pair of adapters, a top and bottom rod connected to said adapters, a shield connected at its bottom to the top rod, a second shield connected to the top rod at one side of the first mentioned shield, means for fastening said shields in a vertical position to a machine frame and forwardly of the transmission shaft and power operating mechanism, one of said shields being adapted to be lowered over the foot pedal of a machine to render the same inoperative.

5. A machine guard of the class described comprising a shield, a supporting rod, means connecting the lower edge of said shield to said rod whereby it may be swung thereon and lowered over the foot pedal of a machine, said shield being bent inwardly and adapted to be fastened in a vertical position to the machine frame, forwardly of the transmission shaft and power operating mechanism.

In testimony whereof we affix our signatures.
