MOTOR MOUNTING.

Application filed May 5,

This invention relates to improvements in motor mountings, adapted for attaching flat type motors to'sewing machine heads.

It is one of the objects of the present invention to providea motor mounting for sewing machines to yieldingly hold the pulley. wheel of the motor in frictional engagement with the machine hand wheel;

A further object of the invention is to provide a -motor mounting constructed so that the motor and mounting may bemanually pivoted away from the hand wheel,-

the pivotal movement being against the tension of a spring whereby when the mounting is released it will automatically return so that the pulley wheel is again in hand wheel engaging position.

A'further object of the invention is to provide a motor mounting of the class described which gives mounting on the end of V the sewing machine head, which is desirable in view of the arrangements of some types of sewing machines.

A. further object of the invention is to provide a motor mounting which is of very simple construction, is strong and durable, and is well adapted for the purposes set forth.

With the above and other objects in view, the invention consists of the improved motor mounting, and its parts and combinations as set forth in the claims, and all the same reference characters indicate the same parts in all of the views: Fig. 1 is an end view of a sewing machine head showing the mounting and a motor held thereby in position;

Fig. 2 is a side view thereof;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2;

Fig. 1 is a fragmentary sectional view of a modified form ofmounting;

Fig. 5 is a front view thereof;

Fig. 6 is a fragmentary cross-sectional view showing a second modified form of motor mounting;

Fig. 7 is a front view thereof;

Fig. 8 is a fragmentary cross-sectional view of a further modified form of mounting; and

Fig. 9 is a front view thereof.

Referring now more particularly to the form of the invention shown in Figs. 1, 2

1926. Serial No. 106,980.

and 3, of the drawing, it will appear that the numeral 12 indicates the head portion of a sewing machine, revolubly carrying a hand wheel 13 of ordinary construction.

Secured to the end of the head by means of a screw 14 is a bracket member 15 bent which is seated and secured a small, flat type electric motor 21. The motor has the usual pulley or drive wheel 22 whichis normally in frictional engagement with the hand wheel 13 to propel the same.

Struckout from the; medial portion of the bracket 15 is a downwardly projectinglip 23. A plate spring member 25, shaped as shown. in Figs. 2 and 3, engages medially thetop of the bolt 17 and its inner end por tion engages under the lip, as at 2 1. The outer end portion of the spring member yieldingly bears under the, outer edge portion of the saddle seat 20.

In use, if it is desired to disengage the motor from the hand wheel, the saddle member is pivoted outwardly.- being released, the spring will return it to normal engaging position.

In the form of motor mounting shown in Figs. 4 and 5, the bracket member 15', Fe cured to the end of the head 12 by a screw Upon its 1 1, is bent at right angles and offset down from the offset portion. The saddle member 19 is similar to that shown in the preferred form of theinvention and a flat plate spring member25 is similarly arranged, the inner end of the same, however, engaging under the lower edge of the offset portion of the bracket, as at 24.

Figs. 6 and 7 illustrate a motor mounting adapted for securementto the side of the head 12. A plate member 26 having a lower struck out portion 26 is secured to the head by screws 14 and is provided with medial, outwardly projecting apertured ears 16 to receive the pivot rod 17. The saddle member 19 carrying the motor 21, is pivotally mounted on said rod in the usual manner and is yieldingly maintained in normal engaging position by-a spring 25 shaped assshown in Fig. 7; The spring, however, does not engage the pivot rod, but is maintained inposition by, being rivetedto tllefitlllCk-Dtlll portion 26 of the plate 26. o

The form of mounting shown in Figs. 8 and 9 requires a fiat portion 12 to be cast and milled on the side of the sewing machine head. and the pivot bolt 17 extends through the projecting ears 2?, thesaddle -19" beingpivotally mounted on the bolt. employed is of a difi'erentcharacter than that shown in th other forms of the invention'. As-clearly shown in Fig. 9 the spring istornied otwire and bent to form a medial engaging portion 29; The spring is also coiled about the bolt, as at 30, and the-inner ends-=thereofare held under the-lower edgeot" the" bracket, as at 243 From the-foregoing descriptionit will be seen that the iinprovedmotor mountingster sewing machine heads are of very simpleand'novel construction, and are well adapted for the purposes set forth.

Whatis claimed as the invention is:

1*; In combination, a-sewing machine head having a hand wheel, abraolretmember rigidlyv secured to the end oi: thehead, said braeketmember havin a ri ht an 'ular oh? A flat bracket 2'? is secured 'thereto The spring 28 tain the motor in a hand Wheelengaging" position.

2. ln-coinbination, a sewingmachine-head having-a hand wheel, a bracketmemben rig idly secured'to said head; said bracket mem-= her: l'iaving an angularly-ofi set p'ort'iom adj a cent the side ofthe' head, bearin'g ears pro jeeting tronrsaid otf set portion, apivotibolt extending therethrough; a saddle member pivotally mounted on-said b'olt; a motor car-' riedby said saddle member; the pulleywheeli ot 'said motor normally being-in engagement with saidhandwheel, and a spring member: engaging its inner end the off' set portion of the bracket and yieldingly engaging at its outer end portion theouter portion of the saddle, said spring serving. to yieldingly maintainthe motor in alian'd wheel engag position. In testimony whereof, I aiiix my signature;
