SEECFCATION forming part of Letters Patent No. 323,943, dated August 11, 1885. Application filed June 26, 1895. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW MARCH, of Lexington, Lafayette county, Missouri,have invented certain new and useful Improvements in Mechanical Motors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to certain improvero ments in .light motors adapted for actuating 2o Fig. 2 is a side elevation ofthe same.

fans, sewing-machines, Snc., the object being to provide a noiseless, compact, and efficient motor of this class.

The invention consists more particularly of a novel combination and arrangement ofwinding mechanism with the other parts, substantially as hereinafter set forth.

ln the drawings, Figure 1 is a front elevation of a motor embodying my improvements. Fig. 3 is a view of the inner side of the main gearwheel, having a portion of the noiseless ratchet mechanism affixed thereto. Fig. 4 is a longitudinal section through the ratchet mechanism and a portion of the winding-drum. Fig. 5 is an enlarged view of a portion of the winding-drum journal and the crank which engages the same; and Fig. 6 is a perspective view of a flexible disk employed in making 3o up the ratchet mechanism.

rllhe letter A indicates a pair of vertical plates, in which are formed bearings for the various shafts. A rod, A, is located between the upper ends of these plates, and is removably held in position by a screw, A2, passing th rough the plates into the end of the rod. The lower ends of the plates A are bent outward at a right angle to form feet, whereby they are securely affixed to a base-plate, S", and to any 4o desirable support.

I prefer to inelose the motor in a dust-proof box, so that it may be protected from injury that it might otherwise receive, and in such casel the letter S would represent the bottom 5 of the box.

winding-drum, g, and a ratchet-wheel h. The

said drum is provided at each end with a disk,

gl, and the ratchet-wheel h may be either attached to one of these disks or it may be formed integral therewith, as desired. i

Mounted loosely upon the end g3 ofthe main shaft, and between the ratchet-wheel and the framing, is the main gear-wheel F, having a pawl, h, pivoted at hl to one of its spokes. u The ratchetwheel h is formed with a recess, g, upon its outer face, and a washer, g, made of spring metal, is located in the recess. The washer gLL is bent in one direction across its diameter, so that when the mainvgear F is pressed against its convex side its periphery will press upon the bottom of the recess 96, as shown.

A pin, h5, projects outward from near the periphery of the washer g4, and an arm, h3, forming a part of the pawl h, has an oblique slot, h4, running a portion of its length,which is engaged by the said pin.

The operation of the ratchet mechanism when thus constructed will be as follows: Upon turning the main shaft toward the left hand in Fig. 8, the friction of the washer g4 against the bottom of the recess in the ratchetwheel h willbe sufficient to cause the washer to revolve therewith, and the pin h5, acting upon the slotted arm of the pawl h, raises the saine and holds it clear of the ratchet-wheel teeth untilthe direction of movement is reversed. The pin in this latter case causes the pawl to engage the teeth, and the main gearwheel will be rotated with the drum. The opening g5 through the washer should be somewhat larger than the diameter of the main shaft, so that after the pawl has been lifted the washer will remain stationary with the main gear until movement of the drumshall be reversed. Y

The end i2 of the main shaft i is circular in cross-section, and projects sufficiently far to allow movement of a crank, N, which is to be used in winding the rope g upon the drum, and therebyraising the weight g2. The letter a2 represents the handle of the crank N. The crank is removable from the main shaft, and the inner end of its body a is formed with a socket, i, and with a spiral surface, i5, for en gaging a pin, i', inserted transversely of the Vmain shaft.

When the crank is in place upon the main IOO shaft, as shown in Fig. l, it is obvious that by turning it in one direction the concave shoulder i, formed at the base of the spiral surface i, will engage the pin t" upon said shaft, and the weight gl' will be wound up; also, that by turning the crank in an opposite direction the spiral surface 5 will simply glide over thepin without turning` the shaft, thereby preventing any accidental strain heilig' thrown upon the ratchet mech an ism From the main gear F power is communicated to the shaft e, carrying pinion e and gear E, thence to the shaft d, carrying` pinion d and gear D, thence to the crank-shaft c, having the crank c2 at about the center of its length, and carrying the pinion cand the gea-r (l, and thence to shaft I), carrying pinion b', beltpulley b2, and iiy-whcel B.

The crank ci may be connected to any style of light lnaehinereq uiring an oscillating' Inovement by means of a connecting-rod, as cic, and the pulley b2 can be used to connect the motor to such machines as require rotary motion.

The letter represents an opening' in the support S for the passage of the weight g2.

Having thus described my invention7 what I claim isw l, In combination with the winding 1nechanisin and the intermediate motive train crank-shaft c, having crank c located at about the center of its length. and carrying pinion c and gear C, shaft located above the entire train, and carrying` fiywheel B, belt-pulley Il, and pinion b', substantially as described. and for the purposes herein set forth.

ln a motor, the combination ofthe drum g, rigidly connected to the main shaft, a ratchet-wheel, lef', revolving with said drum7 and provided with a recess, g, upon its outer face, washer ,f/Qlocated in said recess and fitted with a pin, h5, main gear F, having` a pawl, l, pivoted thereto7 and an arm which projects from said pawl and is engaged by said pin, substantially as described.

3. The combination, with the main shaft provided with a transversely-proiecting pin7 f/, ol' the crank N, formed with a socket, and with a spiral surface and a shoulder, substantially as described.

In testimony whereoillatiix my signature in presence of two witnesses.
