SPECIFICATION for-ming part of Letters'Patent No. 293,624, dated February 19, 1884:.V Application filed December 10,1883. (No model.)
To all 'whom it may concern:
Be it known that I, FRIEND N. BRETT, a citizen of the United States, residing at Sparta, in the county of Monroe andState ofWisconsin, have invented certain new and useful Improvements in Mechanical Motors;v and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of .this specication, andl to the letters and gures of reference marked thereon.
Figure lof the drawingsis an elevation of my improved motor, showing it attached toga sewing-machine, thepcasing of the motor being partially broken away to show the interior construction thereof; Fig. 2, a similarv view, showing a side elevation and the drum of the motor broken away to show the coiled spring; Fig. 3, a sectional view, on an enlarged scale, showing the winding mechanism; Fig. 4, a detail view, showing the winding mechanism in position to operate on the opposite ratchetwheel when the drum is reversed 5 and Fig. 5,
a detailview, in perspective, ofthe 'bandwheel for attachment to the fly-wheel of the sewing-machine. p v
The present invention has relation to that class of motors operated by a coiled spring inclosed within a drum; and the object of the invention is to improve theconstruction of the motor, whereby it maybe readily attached foroperating any of the sewing-machines of different makes, and its action conveniently controlled by the-operator, and the winding and setting of the motor ,greatly facilitated, and the operating parts materially simplied and rendered less liable to get out of order; These several objects I attain by the construction substantially as shown in 4the drawings, and hereinafter described and claimed.
In the accompanying drawings, A represents a suitable frame, to which the several operating parts of the motor are connected, said frame being inclosed by a casing, B, to keep the dust and dirt from the mechanism, and-also give the device a much yneater appearance.
To the sides of the frame A are journaled the ends of a horizontal shaft, a, upon which is mounted the drum C, for inclosing a coiled spring, D, from which the motor obtains its power.'
...To the ends of the shaft a upon the outside of the drum C are secured ratchet-wheels b c, one being a right andthe other a left handed ratchet,the purpose of which will be hereinafter described.
The periphery of the drum C has a central Y line of gear, d,- or, if desired, in place of asin- Secured to the shaft j' upon the outside of the frame A, is a large gear-wheel, E, which meshes with the teeth of a pinion, g, rigidly secured to or'formed with a large belt-pulley,-
F, by means of which the pulley obtains its motion. rIhe shaft of the pulley F has its bearing in one side of the 'frame A and the extension G thereof, vthe outer end of said shaft having keyed thereto a pitman-wheel, 7i, so -that a pitman-connection may be used, instead of belts and pulleys, when found necessary. Over the pulley F'passes a belt or' cord, i, which extends up `over a'grooved Vpulley,-H, detachably connected to the balance-wheel Iof the sewing-machine.
The construction of the wheel orgrooved pulley H is shown in detail, Fig. 5, and is provided Iwith suitable clamps, k, adjustable on the arc of a circle, so as to enable the pulley being attached to balance-wheels of different' patterns or designs. rlhese cl'amps` y consist, preferably, of hooked rods, their shanks being screw-threaded, andextending through elongated slots in the pulley, and held in position by screw-nuts engaging with the screw-Shanks of the hooks, said hooks embracing the spokes of the pulley, asy shown in rig. 2. l
A portion of a sewing-machine table is shown at K, and the usual belt, Z, and balance-wheel I, only so much of the sewing-machine being illustrated as is necessary to show the application of my invention.
IOO
A brake, L, is connected to the frame A, and extension G thereof, or in any manner pivotally supported, so that it will be over the rim of the pulley F, and is operated by a cord, mf, passing over a pulley, n, secured to the under side of the table K, and its end secured to alever, o, also connected to said table. Thus the operater is enabled to control thc speed of the machine by operating the lever with the knee, similar to the knee-swell of an organ. By the employment of the brake, which is, as above stated, controlled by the knee of the operator, the machine can be made ing pivot-ed to one of the inner sides of the frame A. In Fig. 3 this pawl is shown as engaging with the ratchet-wheel c and upon its upper edge.
Loosely and detachably mounted upon theVY end of the shaft a is an arm, M, said arm carrying a spring-dog, o1, which engages with the teeth of the ratchet-wheel. This arm M moves freely upon the shaft c, and has pivoted to its upper end one end of a link, N, the opposite end thereof being pivotcd to ahandlever, O, the lower end of which is in turn pivoted to the inner side of the frame A:
By the arrangement of devices above described, and as shown in Fig. 3, the spring is wound in a direction toward the operator, which adjustment of the winding mechanism renders the motor applicable to a certain class of machines; and to adapt the motor to different class of machines, or those running in an opposite direction, the drum C is made removable from the frame A. After removal, the
.drum C is replaced in a reversed position, to bring the ratchet-wheel b on the side of the frame with the winding mechanism, as shown in Fig. 4, and the spring-pawl p is also reversed, so as to engage with the ratchet-wheel upon its under side, and, if desired, the springdog r may be reversed; but this is not absolutely necessary, as the dog can be so constructed that the necessity of reversing` it will be rendered unnecessary. The lever O is now detached from the frame A, and also from the end of the link N, and then pivoted above its lower end, where the link was formerly connected, to the frame A, and again connected to the lower end or extremity of the lever, this rearrangement of the link and lever being fully shown in Fig. 4. By this arrangement of the winding mechanism the spring is wound by reversing the motion, thus adapting the motor to all classes of sewingmachines, as well as to all the various kinds of small machinery where this class of motor can be used.
The motor may be provided with casters, for convenience of moving it from place to place, and is attached to the machine by hooks extending over the treadle-rod and frame; or any well-known means may be employed for holding the motor stationary.
Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is f l. ln a motor, the combination, with suitable winding mechanism, of a removable and reversible drum, inclosing the usual coiled spring, the shaft of said drum having secured to its ends right-hand and left-hand ratchetwhcels, substantially as and for the purpose set forth.
2. In a motor, the combination, with a rcmovable and reversible drum containing the usual coiled spring, and having upon its shaft right and left hand ratchet-wheels, of an arm loosely mounted on the shaft, and carrying a spring-dog, and an adjustable link pivoted to the arm and to an adjustable lever, substantially as and for the purpose set forth.
3. A mechanical motor consisting of .a reversible drum inclosing a coiled spring, and having right and left hand ratchet-wheels upon its shaft, a reversible pawl to engage therewith, an upright arm loosely mounted on the shaft, and carrying a spring-dog, a pivoted lever, and a link connecting said lever with the arm, both the lever and link being adjustable, to adapt them to the drum when reversed, substantially as and for the purpose specified.
4. In a motor, the combination, with the band-pulley thereof, of a grooved pulley provided with adjustable clamps for dctaehably connecting it to the ily-wheel of a sewing-machine, substantially as and Afor the purpose spcciiicd.
5. A brake mechanism for sewing-machine motors, consisting of a spring-brake arranged over the driving-belt pulley of said motor, and a cord attached thereto, which extends up over a pulley secured to the under side of the sewing-machine table, and its end secured to a pivoted lever, also secured to the under side of the table, and adapted to be operated by the knee of the person sewing, substantially as and for the purpose specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
, FRIEND NEWTON BRETT.
