CHARLES KIDDER, OF NEV BRUNSWICK, NEV JERSEY, ASSIGNOR TO THE MOTOR SEWING MACHINE COMPANY, OF NENV YORK, N. Y.

SPRING-MOTOR.

SPECIFICATION forming part of Letters Pa tent No. 309,961, dated December 30, 1884.

Application filed August 27, 1884. (Xo modem To all whom, it may concern:

Be it known that I, CHARLES L. KIDDER, a citizen of the United States, residing at New Brunswick, in the county ot' Middlesex and State of New Jersey, have invented-a certain new and usefullmprovement in Spring-Motors, of which the following is a clear and exact description, reference being had to the accompanying drawings, and to the letters of reference marked therein, which form part of this specification.

^ My invention is to be applied to and to be used in connection with my spring-motor, which latter forms the subject-matter of two separate patents which have been allowed to me under date of April 23, 1884:, Serial No. 120,715, and August 5, 1884, Serial No. 130,221.

Referring to the drawings, A represents the spring which givesthe propelling power to the mechanism. B is a large crown-wheel,which iorms a part thereof. The power is in this instance transmitted to a sewing-machine by means ofa pinion, C, engaging the said crownwheel, and two pulleys, D and E.

In order to regulate the speed of the mechanism, I apply a pendent brake, F, to the under side of the crownwheel B. This brake F is pivoted at a, being slipped over the main shaft of the spring-motor. A washer, b, of rubber, leatherTox-other suitable material is fastened to the face ofthe brake. The lower part of the lever or brake F extends downwardly and may be actuated upon bymeans of the right foot of the operator as soon assapy pushing or pressing :motion is applied to th`e- .s

end of the same in the direction, as indicated by the arrow in the drawings. A retracting-spring, S, removes' the pressure of the brake from the edge of the crown-wheel B, as 4o soon as the foot ofthe operator releases its hold of the end ofthe lever or brake F.

I am aware that brakes have heretofore been applied to spring-motors-for the purpose herein alluded to, but those are all constructed in 45 the manner of a treadle, necessitating the operator to bear down upon thesame,whereby the brake may be operated by means of compound levers.

It is obvious that my appliance performs the 5o work in an easier way, as hardly any strain is thereby given to the operator.

Figure 1 is a front View of the entire 1nachine. Fig. 2 is a front view of the brake, removed from the machine. Fig. 3 is an edge 55 view of the same.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

In a springmotor, a brake, F, for control- 6o ling the speed ofthe mechanism while running down, so constructed as to swing freely upon the main shaft a, and act upon the periphery ofthe driving-wheel B when pressed laterally toward the right-hand side ofthe machine by 65 the foot ofthe operator,and being drawn away from Contact withsaid wheel by a spiral spring` when the pressure ofthe foot is removed.
