. Application flled'MayG,
To all whom it may concern:
Be it known that I, FREDERICK DIEHL, a
citizen of the United States, residin at Elizabeth in the county of Union and tate of New jersey, have invented certain new and useful Improvements in Sewing-Machine-Motor Brackets, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to sewing machine motor attachments of the type adapted'to be mounted ona sewin machine gooseneck in driving relation wit the sewing machine shaft, and-has for an object to provide an attachment of this type with means whereby the usual bobbin-winder customarily associated with the machine may be driven.
In certain types of sewing machines the bobbin-winder is mounted on the front side of the standard or vertical member of the gooseneck in proximity to the sewing machine balance-wheel so that the bobbinwinder may be pressed against the periphery of the balance-wheel for reception of the power necessary to drive it. In other machines in which there is a forwardly projecting feed-regulating lever mounted on the standard adjacent the balance-wheel and immediately below the main-shaft, the bobbin-winder cannot be mounted on the standard to engage the balance-wheel without interfering with the feed-regulating lever. The bobbin-winder, in such cases, is mounted at a level below the feed-regulating lever and preferably on the sewing machine bed-plate where it may be pressed into contact with the forward limb of the driving belt customarily used in a treadle-driven outfit.
In a motor driven outfit the absence of a treadle-driven belt deprives the bobbinwinder of its customary driving means and the roblem of driving it from a motorattac hment is presented.
-To the attainment of the ends in view there is provided a two-armed bracket adapted to be secured at the juncture of its arms to the usual seat provided at the bal- .is belted to the motor.
1922. serial No. 559,109.
proximity to the bobbin-winder so that the atter may be pressed into engagement with the periphery of such. pulley wheel which The distance of the bobbin-winder pulley from the motor-pulley may be such that a driving belt of standard length-such as is used for connecting the motor to the sewing machine shaft can be used to connect the motor to the bobbinwinder drivingpulley.
In the accompanying drawings Fig. 1 is a side elevation of the attachment as applied to a sewing machine. Fig. 2 is a top plan view of the same; the standard or vertical member of the gooseneck being shown in section, and Fig. 3 is a view showing modification of the invention.
In the preferred embodiment of the inyention, as illustrated, 1 represents the sewing machine bed from which rises the stand ard 2 or vertical member of the ooseneck in which is 1' ournaled the main-sha 3 carrying the balance-wheel 4*, the latter being commonly formed with a hub grooved at 5 to receive a driving belt. The particular machine chosen has the usual forwardly extending feed-regulating lever 6 and is formed with the usual attachment seat 7.
Mounted preferably on the bed 1 of the machine is the usual bobbin-winder which commonly comprises the spindle 8, one end of which is reduced at 9 to receive the bobbin 10 to be wound. The other end of the spindle 8 carries the grooved pulley 11. The splndle 8 is journaled in the spring-pressed rocking frame 12 which is pivoted at 13 to the base-member 14 adjustably secured to the sewing machine bed 1 by the screw and slot connection 151 A spring 16 tends to swing the frame 12 forwardly about its pivot- 13. The frame 12 is held in rearwardly displaced or drivin means of the latch 17 whic engages the shoulder 18 on the frame 12-. The latch 17 is fixed to a shaft 19 to which is also fixed a feeler 20 adapted to ass between the cheek-pieces of the bobbin being wound. When the frame 12 is pressed rearwardly the latch 17 moves under the shoulder 18 and holds the frame in winding position with the grooved pulley pressed against the usual belt heretofore used to connect the pulley 5 with the usual treadle-operated wheel beneath the bed 1. As the bobbin fills with thread the feeler 20 is displaced position by spring 16 to interrupt the forwardly until, when the bobbin is full, the latch 17 1s carried forwardly sufficiently to release the frame 12 which is thereupon shifted forwardly about the ivot 13 by the riving relation between the pulley 11 and the belt.
In accordance with the present improvement the machine is driven by a suitable electric motor 21 having preferabl a doubly grooved pulley 22 connected by a belt 23 of standard length to the pulley 5. The motor is preferably secured by screws 24 and a riband-groove connection 25 to the inclined end 26 of one arm 27 of a bracket 28 adapted to be secured by a screw 29 to the seat 7 previously referred to; such seat 7 being customarily provided on the standards of sewing machines of various well known types. The inclination of the arm 26 and rib 25 is preferably such that it is erpendicular to a line joining the centers 0 the pulleys 5 and 22, whereby adjustment of the motor along the arm 26 may be effected without appreciably altering the belt length as disclosed in the application of Martin Hemleb, Serial No. 383,708, filed May 24, 1920.
The bracket 28 is formed with. a forwardly extending arm 30 at the end of which a pulley 31 is mounted by means of a bearing screw 32. The pulley 31 is preferably formed witha belt groove 33 and driving surface 34 againstwhich may be pressed the rubber ring 35 fitted to the pulley 11 of the bobbin-winder. The distance between the centers of the pulleys 22 and 31 is such that the sewing machine driving belt 23 or another belt of standard length may be used.
The pulley '11 may have the friction ring 35 omitted and may be arranged to bear directl upon the belt 23, as shown in Fig. 3. f
Having thus set forth the nature of the invention, what I claim herein is s 1. A sewing machine drivingattachment comprising a bracket adapted to besecured to the usual attachment seat on the gooseneck of a sewing machine, and a sewing machine driving motor and bobbin-winder pulley mounted in spaced relation on said bracket and adapted to be connected together motor for transmission of power from said to said pulley. I 2. A sewing machine driving attachment comprising a bracket adapted to be secured e gooseneck of a sewingmachi'ne and having oppositely extending arms, a drivingmotor mounted on one of said arms, and a bobbin-winder pulley mounted on the other of said arms and adapted to be belted to said motor.
3. A sewing ma hine driving attachment comprising a bracket adapted to be secured to the gooseneck of a sewing machine, a driving motor and a bobbin-winder pulley mounted in spaced relation 'on said bracket and adapted to be connectedtogether by a belt, said bobbin-winder pulley having a beltgroove and a driving surface into frictional engagement with which a bobbin-winder may be pressed.
4. The combination of a sewing machine outfit including a frame, a sewing machine pulley and a bobbin-winder pulley, of a bracket secured to said frame, a motor mounted on 'said bracket and having a shaft and driving pulley, a belt connecting the motor and machine, and a pulley mounted on said bracket in spaced relation to said motor and adjacent the bobbin-winder.
5. The combination of a sewing machine outfit including a frame, a sewin machine pulley and a bobbin-winder p e of a bracket secured to said frame, a motor mounted on said bracket and having a shaft and driving pulley, a belt connecting the motor and machine, and a pulley mounted on said bracket adjacent the bobbin-winder, the
- distance between the centers of the last mentioned pulley and the motor-shaft being such that a belt of standard length such as used for driving the sewing machinecan be used for winding bobbins.
6. The combination with a sewing ma- .chine having a bed, gooseneck, main-shaft pulley, and bobbin-winder mounted on said bed adjacent the base of the gooseneck, of a bracket mounted on said gooseneck,a motor mounted on said bracket, .a belt connecting the 'motor and mainshaft pulley, and a bobbin-winder driving pulley mounted on said bracket in spaced relation to the motor-pul- "ley and adapted to be belted to said motor.
In testimony whereof, I have signed my name to this specification.
' FREDERICK DIEHL.
