HARRISON D. FLEGEL, OF RACINE, WISCONSIN.

SEWING-MACHINE-MOTOR BRACKET.

Application filed October 9, 1923.

Objects of this invention are to provide i standard type of sewing machine without requiring alterations thereof, which will hold the driving motor in correct position relative to the driven wheel of the sewing machine head, which is provided with means for correctly proportioning the pressure between the driving wheel of the motor and the driven wheel of the sewing machine head, and which is provided with an adjustment whereby the device is adapted to cooperate with any of the usual types of sewing machines.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a plan view of the bracket in position.

Figure 2 is a sectional elevation on the line 22 of Figure 1, certain portions being broken away to more clearly illustrate the construction.

Figure 3 is a front view of the bracket detached from the machine and motor.

As shown in the drawings, the device is adapted to be attached to the usual sewing machine head which comprises an upright standard 1, and a laterally projecting portion 2,-such sewing machine head being provided with a driven wheel 3 laterally ofiset with reference to the body portion and with a spool receiving vertical pin 4 projecting upwardly from the head.

The bracket comprises ahorizontal supporting member 5 which is provided with an aperture 6 therethrough adapted to receive the lower portion of the pin 4 and with an upstanding vertical portion 7 paralleling such-pin. This vertical portion terminates in a laterally projecting portion 8 provided with a V-shaped aperture 9, as shown in Figure 1., adapted to receive such If desired, the lower aperture 6 may Serial N0. 667,468.

also. be V-shaped. A screw 10 is threaded through the vertical portion 7- and is adapted to engage the pin 4 and to force the pin into engagement with the slanting portions of the V-shaped apertures to thus positively lock the device to the pin.

Upon the support 5, a horizontal portion 11 of a curved arm 12 is carried. This horizontal portion 11, as shown in Figure 1, is provided with an elongated slot 13 through i which the stems of a pair of screws 14 pass,such screws being threaded into the support 5 of the bracket. The curved arm 12 is contoured to fit the casing of the motor 15, as shown in Figure 2, and is secured thereto by means of screws 16 or in any suitable manner. A laterally extending dished arm 17 projects from the curved arm12 and is integrally formed therewith. This laterally projecting arm is provided with a flat portion 18 (see Figure 1) through which is threaded a screw 19, such screw being provided with a lock nut 20.

In view of the fact that the spool receiving pin 4 is utilized, a second spool receiving pin 21 is provided and is carried by a portion 22 of the support 5, as shown in Figures 1 and 3.

In using this device, the bracket is secured to the motor, as stated, and is slipped over the pin 4. Thereafter the screw 10 is tightened to hold the device in position. The screw 19 is then adjusted so as to press against the head of the machine and rock the motor about the pin 4 thus bringing its driving wheel 23 into contact with the driven wheel 3 of the sewing machine with the requisite amount of pressure. Thereafter, the nut 20 is screwed down and thus locks the screw 19 in adjusted position.

It will be seen that an attachment for a sewing machine has been provided which is of extremely simple construction, which may be most readily produced, which will cooperate with any of the standard types of sewing machines, which is adapted. for adjustment to accommodate variations in the design of the sewing machine, and in which means are provided for regulating the pressure of the driving wheel of the motor a ainst the driven wheel of the sewing ma- 0 me.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously em wardly therefrom and having a driving wheeha bracket adapted to receive said pin and having an arm projectinglaterally therefrom andadjusting means carried by said arm and adapted to bear against the side of the head of said machine,- and a driving motor carried by said bracket and having a driving wheel adapted to engage the driven wheel ofsaid sewing machine head.

In a device of the class described, the combination of a sewing machine head having a spool receiving pin projecting upwardly therefrom and having a driven wheel, a bracket 'removably positioned upon said pin, clamping means carried by said bracket and adapted to engage said pin, said bracket having a laterally projecting arm, a screwcarried by said arm, and adapted to engage the side of said sewing machine head, and a motor carried by said bracket and having a driving wheel in engagement with the driven wheel of said sewing ma. chine head.

4. In a device of the class described, the combination of a sewing machine head having a spool receiving pin projecting upwardly therefrom and having a driven wheel, a two part bracket having one portion adapted to removably receive said pin, clamping means carried by said portion and adapted to engage said pin, said bracket having a second portion-slidably related lo said first mentioned portion and having a laterally projecting arm,a screw carried by said laterally projecting arm and adapted to engage the side of said sewing machine head, and a motor carried by the said portion of said bracket and having a driving wheel in engagement with the said driven wheel.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of \Visconsin.
