JOHN THOMAS WINBURN, vOF SUMTER, SOUTH CAROLINA.
SEWING-MACHINE MOTOR.
SPECIFICATION forming part of Letters Patent No. 331,666, dated December 1, 1885.
Application filed October 13, 1885. Serial No. 179,802. (No model.)
To all whom it may concern.-
Beit known that I, J CHN T. WINBURN, a citt zen ofthe United States, residing at Sumter, in the county of Sumter and State of South Carolina, have invented certain new and useful Im provements in Sewing-Machine Motors; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure l of the drawings is a representation of a front elevation, partly in section. Fig. 2 is an end elevation, partly in section.
This invention relates to improved means for winding up coiled springs used as motors for light mechanism-such as sewing-machines; and it consists, essentially, in connecting such a spring to a lever or foot-board pivoted at its center by mechanism in such a manner that a person standing with each foot on one end of the lever and throwing his weight alternately in each foot will wind up the spring.
It further consists in certain details of construction and arrangement hereinafter described, and pointed out in the appended claim.
The spring is preferably connected permanently with a train of wheels running a pulley, a belt from which may operate the sewing or other machine; but this is not essential to the invention.
Referring to the accompanying drawings by letter, A designates the frame of the machine, of rectangular box form, divided 4longitudinally by the partition a.
B is a foot-board lever or double treadle, having attached centrally the transverse oscillating shaft B', which has bea-rings in the uprights Zi b', rising centrally from one side of the frame A and from the partition a, respectively.
C is a transverse shaft below the shaft B', and having bearings on both sides of the frame andin the partition a, and G is a ratchet-wheel fixed thereon vertically below the double treadle B. The arms of said treadle are designated by the letters X and X', respectively. To the lower surface of the treadle, near the end fr, is secured a bracket, D, between the depending arms of which is pivoted one end of a link-bar, d, the other end of which is pivoted between the upper ends of the similar parallel bars, d d. Thelower end of the said bars are united by a short rod, di, arranged to enga-ge between the teeth of the ratchet-wheel C. The rod d2 is held up against the ratchetwheel by means of a coiled spring, d, one end of which is connected to the bars cl, and the other end wound loosely around the shaft C, so as not to turn with the latter. To the lower surface of the treadle, near the end x, is secured a bracket, E, the single depending arm of which is pivoted between the upper ends of the similar parallel bars, e, between the lower ends of which is pivoted the upper end of a vibrating lever, e, which is itself pivoted about centrally'upon an upright, e2, rising from the door of the main frame A. The lower end of the lever is pivoted between the lower ends of the bars e3 e3, the upper ends of which are united by a shaft-rod, et, similar to the rod d2.
e5 is a coil-spring connected by one end to the upper ends of the bars e3, and attached to the shaft C similarly to the spring d3. -The spring c5 serves to keep the rod e* against the ratchetwheel G', with which it engages. The mechanism on each side of the shaft C is so relatively arranged that when the rod e* is engaging and moving the teeth of the ratchetwheel the rod d2 is sliding over the same, so that a person standing on the double treadle with one foot on each end, and vibrating the same by alternately throwing his weight on each foot will rotate the ratchetwheel,and consequently the shaft C, continually or with slight stops only when the treadle reverses motion.
F is a gear-wheel turning loosely on the shaft C near the side of thefraineA opposite to that adjacent to the treadle, and provided near its periphery with the inward standing arm f.
G is a strong coiled leaf-spring having its outer end secured to the arm f ofthe gear-wheel and its inner end secured to the shaft C.
H is a standard-frame rising from the partition a and the side ofthe frame adjacent to the gear-wheel and having bearings on it for the shafts I and J. The shaft l carries the gear-wheel t and the pinion t', which meshes with the gear-wheel F. The shatJ carries-the pinion j ,arranged to mesh with the gear-wheel t', and on its end extended outside of the frame H a pulley, j', from which a belt .can be run to the drivingpulley ofthe sewing or other light- Working machine.
As the gear-wheel F is loose or does not turn with the shaft C, and as the inner end of the spring G is connected to said shaft, it is evident that the rotation of the shaft tends to Wind up the spring and to cause the described train 0f gearing t0 rotate and actuate the machine connected therewith. The train of Wheels is only for the purpose of causing the spring to act with less force upon the machine driven, and consequently prolonging its action.
Io act in less time and with more force, the gear-Wheel F might be replaced by a disk turningloosely on the shaft C, or the said shaft might :be extended outside of the frame and a pulley iixed thereon; but for lightwvorking machines the accelerating-train is necessary.
' It is evident that the described manner of. Winding up the actuating-spring G can be performed With much more ease and much `more rapidly than by Winding up the saine by .Having described my invention,1what I claim and desire'to secure by Letters Patent, is-
In a machine to wind up coiled motorsprings, the combination of the shaft C, the ratchet-Wheel secured thereto, the gear-Wheel or disk turning loosely thereon,and the motorspring having its outer endsecured to the said gear-wheel or disk, and its inner end secured to the shaft C, With the double treadle, the brackets D and E, link-bars d and @vibrating lever c', pivoted on the upright e2, bars c2, coiled springs d3 and c5, and paWl-rods d2 and e4,arranged to act alternately in engaging and turning the ratchet Wheel, substantially as specified.
In testimony whereof I afx iny signature in 4o Clans. H. Moisn, D. J. AULD.
