HENRY WARREN AND CHARLES H. LUTHER, OF PROVIDENCE, R. I.
IMPROVEMENT IN MOTIVE POWERS FOR OPERATING SEWING-MACHINES.
Specification forming part of Letters Patent No. 129,998, dated July 30, 1872.
Specification describing a new and Improved Sewing-Machine Power, invented by HENRY WARREN and OHARLEs H. LUTHER, of Providence, in'the county of Providence and State of Rhode Island.
Our invention consists of a novel and efficient arrangement of a spring winding, holding, regulating, andtransmitting apparatus, for adapting the same for application to sewing-machines, all as hereinafter described.
Figure 1 is a front elevation of the apparatus with a part sectioned, and Fig. 2 is a horizontal section taken on the line av 00 of Fig. 1.
Similar letters of reference indicate corresponding parts.
A is a crank-shaft mounted in the housings B, with a drum, C, inclosing a spring, D, fixed loosely on it, said spring being connected at its outer end to said drum, and at the inner end to the hub E made fast to the shaft. The face of this drum gears with a small roller, F, by frictional contact, to transmit the motion through the shaft H and pulley I. K is a disk at one side of the drum, attached to't-he brackets L, projecting from one side of the frame. M, on the outside, for holding the shaft A after the spring has been wound up by a pawl, N, pivoted on the arm 0 of said shaft. P is a friction-holding disk on the side of the drum, opposite to the one where the ratchet is arranged. lts hub is pivoted in the ends of the crotched shifting-lever Q, which is pivoted on the bracketR. This disk, being pressed against Said disk has a ratchet;toothed hub,
the side of the drum, will stop the machine or slow the motion, as required. It also holds the disk while winding up the spring, which is done by turning the hand-crank T.
The drum A and wheel F may be geared together by teeth instead of by frictional contact, as preferred; but, when arranged as here shown, the bearings V will be made adjustable toward and from drum A, and provided with adjusting-screws V, or other equivalent means for adjusting them. The motion will be transmitted to the sewing-machine from the pulley I.
This arrangement affords a simple and efficient apparatus, which may be wound up by a few turns of the crank, and will run a sewing-machine or other light machinery very much longer than the time required to wind
