MOTOR.

SPECIFICATION forming part of Letters Patent No. 281,858, dated July 24, 1883.

Application filed June 8, 1883. (No model.)

To aZZ whom it may concern Be it known that I, J AMES R. FOR1),.of Buena Vista, in the county of Chickasaw and State of of reference marked thereon, which form part.

of this specification. I r

This invention has relation to the class known as mechanical movements, motors, and for eonvertingmotion. v

It has for its object to operate light machinery, such as sewing-machines, roek-drills, rock cradles, fly-brushes, churn-pumps, &c.; and the invention consists in certain combinations of devices, as will be more fully hereinafter described, and particularly pointed out in the claims.

Referring to the drawings, of which there are two sheets, Figure 1 represents an elevation of one side of my machine; Fig. 2, an elevation of the opposite side; Fig. 3, a top plan View of the same, and Fig. 4 a detail of the adjustable crank-arm.

Referring to Fig. l, A is the frame, of ordinary construction, and B the frame upon which themachine is mounted. O is the fly-wheel, whose momentum regulates and equalizes the power of the machine in the transmission of motion. D is the cog-wheel,which meshes into a pinion, a, on the fly-wheel shaft E. (Clearly shown 011 Fig. 3.) F is a shaft intermediate of the power-shaft G and the driving-shaft E,

a and carries a pinion, b, which meshes with the cog-wheel H upon the power-shaft G. I also locate on the power-shaft G a sleeve, to which a ratchet-wheel, c, is attached. This ratchetwheel is for the purpose of holding the machinery still when it is desired to stop the operation of the machine andfits connecting mechanism. I I are two springs of suitable resiliency and .powcr to impart motion to the machine. Other motive power may be adapted to produce the same result without departing from the spirit of my i 'fvention.

All these shafts are suitably journaled in any approved manner, and the cog-wheels and pinions secured in the usual way. At Fig. 1 it will be seen that a crank-arm is secured to the driving-shaft E, to which is secured a link or connecting-rod, d, which in turn is connected to the end of a pendulum arm or lever, c, and which is pivoted in a bifurcated bracket-arm, f, which is secured to the frame 13. This bifurcated bracket arm is provided with an elongated slot, to allow the free vibration of thependulum-arm 0. Arm 6, at its lower end, is provided with a pendulum-weight, h, which may be adjusted up or down 011 said arm. The object of this adjustment is to increase or diminish the speed of the instruments attached to the machine.

Referring to Fig. 2, which shows the other side of the machine, and upon which will be seen the mechanism attached for various pur' poses. Upon the side of the frame B, I locate a bracket-arm, i, sufficiently far from the frame to permit the crank j to turn between it and the frame. The end of bracket 1 forms a guide for rod k, which has a vertical up-and-down movement, and which may be applied to a rockdrill, churn, cradle-rocker, or other apparatus. This rod has suitably pivoted to it some distance below its upper end a connecting link or rod, I, which also connects to the adjustable crank-army, which is secured to the main driving-shaft. I will now describe this crank, which is of peculiar construction, as follows: This crank is made with an elongated slot, 121, for the reception of the end of the drivingshaft, which end is made to slide in said crank to any desired point within the slot. The edge of the crank is provided with a se ries of holes, a, for the reception of a pin, which pin passes through the end of the shaft, also, whereby it is held in position. It is evident that a set-screw or other means of attachment may be adapted for holding the end of the shaft in position. The object of the slot is to regulate the throw or length of the vertical movement of the rod or other levers.

Should it be desirable to apply this power to a horizontal movement, the 'linkl is detached from the rod 7t and attached to a pivoted rod, 0, (shown in dotted lines,) which rod 100 2. The combination, with motive power mechanism such as herein described, of the frame, the bracket i, having guide-bearing for rod k, with said rod, and with connecting-link Z and crank j adjustabiy secured to the end of the driving-shaft, as set forth.

In testimony that I claim the foregoing as my own I aifix my signature in presence of two witnesses.
