UNITED STATES PATENT OFFICE.
JOHN H. ARCH, OF JACKSON, GREENE COUNTY, IOWA.
MOTOR.
SPECIFICATION forming part of Letters Patent No. 403,317, dated May 14, 1889.
Application led November 28, 1888. Serial No. 292,087. (No model.)
To all whom, t may concern:
Be it known that I, J oHN H. ARCH, a citizen of the United States, residing at Jackson township, (post-office address Scranton,) in the county of Greene and State of Iowa, have invented certain new and useful Improvements in Motors; and I do declare the following to be a full, 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 the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to motors that are run by springs, and which are designed to run light machinery, such as scroll-saws, lathes, grinding-stones, sewing-machines,&c. The motor is controlled bya pendulum and escapementwheel, and the shaft from which the power is taken is adjustable to adapt the motor to machines of different heights.
The improvement consist-s of the details of construction, which hereinafter will be more fully described and claimed, and which are shown in the annexed drawings, in Which- Figure l is a front view, parts being broken away, of a motor embodying my invention; Fig. 2, a top plan view; Fig. 3, a detail view showing the manner of adjusting the shaft from which the power is taken, and Fig. et a detail perspective view of a modification.
The sides A and B, which form the supports for the train of gearing, are held together by the brace-bars a. The winding-arbor B is provided with the gear-wheel C and with the drum D, on which the spring E is wound, the lower ends of the spring being carried down and secured to the post c. The inner end of the drum has the ratchet-teeth d, which are engaged by the pawl c in engagement with the The gear-wheel C meshes with the pinion f on the shaft F, and the gear-wheel g on the shaft F meshes with the pinion h on the shaft II. The gear-wheel@ on the shaft H is in mesh with thepinion j on the adjustable shaft J. The curved bars K, held to the sides A and B and concentric with the shaft II, have a series of openings, k, in their length, through corresponding pairs of which openings the thumb-screws L pass and screw into threaded openings j in the ends of the shaft J. By removing the thumb-screws L the shaft J can be raised or lowered to adapt the motor to machines of varying heights. Vhen the shaft is adjusted, the thumb-screws are replaced and form journals for the said shaft.
The Speed of the motor is controlled bythe scape-wheel in on the shaft M, the pallet-lever N, and the pendulum n. The shaft M is in gear with the wheel g through the pinion o, mounted thereon. The power is taken from the adjustable shaft J by any well known means, as the belt P, which passes over the band-pulley Q on the shaft f.
In Fig. 4 the shaft is vextended at one end and passes through one of the curved bars, and the other end is held bya set-screw. The extended end is provided with an angular opening or is otherwise constructed to receive a tumbling-shaft. In case a belt be the means for conveying the power any slack may be taken up in the same by adjusting the said driving-shaft.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-- l. In a motor, the combination of the curved bars having openings, the adjustable shaft J, having threaded openings in its ends, and the thumb-screws, substantially as and for ,the purpose described.
2. The herein described and shown motor, composed of the sides A and B, the shaft B', having the gear-wheel C, the drum D, and the ratchet-andpawl connection between the drum and the gear-wheel C, the shaft H, having the pinion 7L and the gear-wheel Iz', the shaft J, having a pinion and threaded openings in the shaft ends, the curved bars K, having a series of openings, the thumb-screws L, and the escapement, combined, arranged, and operating substantially as and for the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN H. ARCH.
