JACOB ZUGKERMAN, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT lN FRICTION-BRAKES FOR POWER SEWING-MACHINES.
Specification forming part of Letters Patent No. 44,909, dated November 1, 1864.
To all whom it may concern:
Be it known that l, J. ZUCKERMAN, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Power for Sewing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a side elevation of this invention. Fig. 2 is a transverse vertical section of the same.
Similar letters of reference indicate corresponding parts.
The manifold attempts heretofore made to drive sewing-machines by spring or weight power have all been failures, principally for the want of a suitable device to regulate the speed of the machine. It a spring or weight is applied powerful enough to overcome the inertia of all the working parts and'to start the machine, it. (the machine) soon begins to race and to assume a speed quite incompatible with the successful operation of sewing, and if the spring or weight has not sufticient power to start the machine the whole device is useless. These difticulties are overcome by the power which forms the subject-matter of this invention. It consists in the application of an adjustable friction device or regulator acting upon the fly-wheel of the sewing-machine and used in combination with a series of gear-wheels, to which motion is impart ed by a spring or weight, and from which motion is transmitted to the main drivingshalt of the sewing-machine and through it to all the working parts of the same in such a manner that the motion or speed of the sewing-machine can be regulated independent of the power of the weight or spring, and a weight or spring can be employed of sufficient power to work the machine for a long time without winding up.
A represents a sewing-machine of any of the well-known constructions. This machine is firmly secured to the base B, and on the end of its main driving-shaft O is mounted the cog-wheel D, which gears in a similar cogwheel, E, on an arbor, a. This arbor has its bearings in a frame, F, secured to a base or bed-plate, G, and it bears a pinion, b, to which a rotary motion is imparted by a train of gearwheels, H I, and pinion c, and by a weight or spring applied to the arbor of the last gearwheel, I. This wheel is arranged with an on dinary winding-up device, so that the weight or spring can be wound up whenever it may be desirable; and in order to facilitate this operation acog-wheel, J, is mounted on the end "of said arbor, and this cog-wheel gears in a pinion, K, on the arbor cl, the end of which is square to receive the barrel of the key or wrench used for the purpose of winding up thepower. The motionimpartcd by the weight or spring to the train of wheels is transmitted to the main shaft of the sewing-machine by the wheels 1) E, and a suitable train of wheels,
working parts of the sewing-machine in the ordinary manner.
0 is the fly-whecl, which is mounted 011 the drivingshaft O, and a frictionregulator, P, is secured down upon the edge of the base B of the sewing-machine. This regulator consists of a slide, 0, which is adjustable toward or from the circumference of the fly-wheel O by a series of nicks, f, and spring-pawl 9, (see Fig. 2,) and by the motion of the slide the friction-pad It can be pressed with more or less power against the circumference of the flywheel, or it can be relieved from the same and brought in the position shown in Fig. 2. By this friction-regulator the motion of the sewing-machine can be readily stopped or the speed regulated, as may be desirable, and the spring or weight power can be used with perfect suc cess.
1 claim as new and desire to secure by Letters laten t The combination and arrangement of the bent arm P and pad h with the slide a, notches f, and spring-pawl g, operating substantially in the manner and for the purpose described.
