WEIGHT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 502,814, dated August 8, 1893.

Application iiled June 17, 1893.

To all whom it may concern:

Be it known that I, DIEDRICK J. FREEsE, a citizen of the United States, 'residing at Higginsville, in the county of Lafayette and State of Missouri, have invented a new and useful Weight-Motor, of which thefollowing is a specication.

The invention relates to improvements in weight motors.

The object of the present invention is to improve the construction of weight motors, and to provide simple and effective means, whereby heavy weights may be easily and quickly elevatedfor the purpose of furnishing the motive power.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a side elevation of aweight motor constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional view.

Like numerals of reference indicate corresponding parts in both the figures of the drawlngs.

1 designates a main frame, provided at the back with a vertical extension 2, forming a well or way for weights 3 and 4; the main frame has journaled on it a power shaft 5, which carries a drum 6; and extending from the drum are cables 7 and 8, which pass over pulleys 9 and 10 and are connected to the weights 3 and 4. The cable 7 extends upward from the front side of the drum to the top of the weight well or way; and the other cable 8 extends downward from the rear side of the drum and passes around a pulley roll 11 and then upward to the pulley lO. This arrangement of cables equalizes the strain on the drum and enables heavy weights to beemployed without racking or straining the gearing. A train of gear wheels 12 connects the power shaft 5 with a drive shaft 13; and the latter is connected by a train of gear wheels 14 with a governor 15, which regulates the speed of the motor and the distribution of the power. The drive-shaft 13 carries a drive pulley 16 from which motion may be commu- Serial Na. 477,935. (No model.)

nicated to any machinery, and one or more drive-wheels or pulleys may be employed. The drum 6 is connected with the lowermost gear wheel 17 of the train 12, by a clutch consisting of a check pawl 18 and a ratchetwheel 19, whereby the gear wheel 17 rotates with the drum when the latterk is actuated by the weights. The weights are wound up by alever 20 and a platform 21, which are fulcrumed on the main frame, and are connectedby a rod 22. The lever and the platform are provided at their rearends with longitudinal slots 23 and 24 to enable them to be adj usted longitudinally to regulate the lifting power; and the rod 22 is provided at its ends with clips 25, and is attached to the lever in advance of the fulcrum 26, and to the platform in rear of the fulcrum 27 on an extension 28 of the platform, whereby an upward movement of the lever will force the platform downward, thereby enabling the strength of a person to be utilized to its greatest advantage in assisting his weight to force the platform downward. The adjustability of the connecting rod 22 in connection with the longitudinal slots 23 and 24 enable the desired leverage to be readily obtained.

The platform is provided in advance of the ratchet wheel with a pivoted depending spring actuated pawl 29 Y for actuating the ratchet wheel for winding the cable on the drum. The pawl 29 is held in engagement with the ratchet wheel by a curved resilient inner end 30 of a longitudinally movable rod 3l, which is connected by a link 32 with an outer hinged section 33 of the platform. The hinged section 33 is adapted to be swung upward against the main frame, in order to be out of the way after the operation of winding up the weights is completed; and when swung upward, the hinged section 33 of the platform through the link 32 draws the pawl 29 out of engagement with the ratchet wheel. As soon as the outer hinged portion of the platform is lowered to a horizontal position the actuating pawl 29 will be carried into engagement with the ratchet wheel. The longitudinally movable rod 31 is arranged in guide eyes 34 of bolts, and is located on the lower face of the platform.

The lever 2O is provided with asliding outer section 35, which telescopes into the body of the lever when the winding mechanism is not in use.

It will readily be seen that the winding mechanism of the weight motor maybe readily adjusted to obtain the desired leverage to enable heavy weights to be conveniently raised; and that the power thus obtained may be readily transmitted to any desired machinery or device to be operated.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
