WEIGHT-MOTOR AND GOVERNOR MECHANISM.

SPECIFICATION forming part of Letters Patent No- 707,377, dated August 19, 1902.

Application filed 06th., 10,1901. Serial No. 78,214. (No model.)

To alt whom it may concern.-

Be it known that I,WILLIAM D. BELL, a citizen of the United States, residing at Slayton, in the county of Murray and State of Minnesota,have invented certain new and useful Im provements in VVeight-Motors and Governor Mechanism; 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 makeand use the same.

The invention relates to a power-transmitting device.

The object of the invention is to provide a simple, durable, and inexpensive machine of this character for converting a transmitted reciprocatory or variable rotary motion into a uniform rotary motion, the power thusreceived being stored for future use when needed. 1

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be more fully described, and particularly pointed out in the appended claims. I I

In the accompanying drawings, Figure 1 is a perspective view of one embodiment of a machinefor carrying out my invention. Fig. 2 is a top plan view; and Fig.3 ,is an end view of the axes of the two winding-drums, showing the pawl-and-ratchet connection between them and the gear-wheels carried at the ends of the drums. Fig. 4 is a detail sectional view of one of the winding-drums, its pawl and ratchet, audits gear-wheel. Fig. 5 is a detail view of certain parts composing the clutch-shipper.

Referring now more particularly to the drawings, 1 denotes the framework of the machine, and 2 and 3 denote winding-drums, each of which is provided with stub-axles journaled in suitable hearings in the framework.

4 and 5 denote beveled gear-wheels fixed to the stub-axles atone end of j the drums, and 6 and 7 denote gear-wheels connected to the stub-axles at the opposite ends of the drumsby pawls and ratchets 8 and 9, respectively, whereby said drums are permitted to rotate in one direction without turning their gearwheels and when rotating in the opposite direction will positively turn their gear-wheels.

1O denotes a drive-shaft suitably journaled in the framework of the machine and provided with loosely-mounted beveled gears 11 and 12, designed to be locked to said shaft and drive thebeveled gears 5 and 4, respectively. Any suitable means may be employed for effecting this; but that shown in the accompanying drawings is preferred, and comprises a sleeve 13, having at opposite ends clutch members 14 and 15, whichv are adapted to be engaged with corresponding clutch members 16 and. 17, carried by the gears 11 and 12. The sleeve is splined to said shaft to rotate therewith and slide thereon by a pin ,18, which projects through a longitudinal slot 19, formed in said sleeve.

20 denotes a rope or cable doubled upon itself and passed over one or more sets of pulleys 21 and at its bight supports a weight 22. The ends of this cable or rope are one seemed to the drum 2 and the other to the drum 3.

23 and 24 denote reversing devices, which, as shown, comprise bars hinged at one end to the supporting-frame and provided with longitudinal slots 25 and 26, through which the runs of the'rope or cable work.

28 denotes a clutch-shipper, which consists of a pivoted fork 29, which engages a grooved collar 30, carried by the sleeve. Rods 31 are pivoted to this lever and extend through the ends of. boxes 33 and are provided with coiled springs 34, which are confined between nuts carried by the outer ends of said rods and the inner ends of the boxes. The outer ends of said boxes are connected by ropes 35, which pass under pulleys 36, secured to the framework of the machine, and through the free ends of the reversing-bars.

37 denotes a suitably-supported shaft carrying at one end a gear-Wheel 38, which is constantly in mesh with the gear-wheels 6 and 7 ,and provided at its oppositeend with a gear-wheel 39, which mesheswith a gearwheel 40, carriedby a shaft 41to be driven.

The operation of the device is as follows: Assuming the parts to be in the position shown in Fig. 2 and power supplied from any suitable source to the shaft 10, the power from movement, its gear-wheel 6 being locked to it, said gear-wheel will transmit the motion from said drum, which motion is steady and uniform, due to the pull of the weight, to the gear 38, and through the intermediate gearing to the shaft ail, from which the power is transmitted to the machine to be driven. It is of course understood that the weight is of sufficient gravity as to be equal to the occasion of running the machine to be driven, and in order to control the movement of the shaft 41 any suitable form of governor or brake (designated by the letter 00) may be employed for the purpose of limiting the speed of the power-transmitting device, so that the machine driven will be under complete control, or, if desired, the machine driven may be equipped with such a governor or brake. It being assumed that the machine to be driven is in operation and power is at the same time being transmitted to the shaft 10 and the machine to be driven is under the complete control of its brake or governor, the rope or cable 20 will be successively wound and un wound from the drums 2 and 3 and the weight 22 will be bobbing up and down and acting somewhat in the nature of a governor to transmit the variable motion received by the shaft 10 from its source of power to the drums 2 and 3, and thus the weight will cause a uniform power to be transmitted to the shaft 41 to drive the machine; but of course the power transmitted to the machine will be considerably less than that received by the shaft 10, owing to the loss of power due to friction. Now assuming that the machine to be driven is at a state of rest, or, in other words, it is out of operation for the time being, it is evident that when power is transmitted to the shaft 10 and the shaft 41 is held against rotation it will elevate the weight to its highest point, and thus the weight will be retained at that point until it is desired to transmit the power stored by the elevated weight to the machine to be driven. It will thus be seen that the device when thus used acts as a power-storing device in that it stores power which would otherwise be wasted, and the stored power is capable for use for driving machinery when it is so desired. Now coming back to the operation of the machine when it is in the position shown in Fig. 2 and power is transmitted to the shaft 10 and through the gear-wheels 5 and 11 to the drum 2, said drum will be rotated to wind up the rope or cable, and as this drum is rotated the drum 3, upon which the cable was previously wound, will be unwinding, and in its unwinding movement, its gear-wheel 6 being locked to it, said gear-wheel will transmit the motion from said drum, which motion is steady and uniform, due to the pull of the weight, and this motion will be transmitted to the gear 38 and through the intermediate gearing to the shaft 40. In this rotation of the gear 38 the gear 7 of the drum 2 will slip upon its stub-shaft in a direction opposite to that in which the drum is being rotated. As the rope continues to unwind from the drum 3 a knot a in the rope will come in contact with the reversing-bar 24. and will elevate said bar, thus moving the clutch-sleeve 13, with its clutch member 14, from engagement with the clutch member 16 and throwing its clutch member 15 into engagement with the clutch member 17 of the gear 12, so that the movement from said shaft 10 will be transmitted to the drum 3 to wind the rope or cable thereon, and the drum 2 will be released to permit it to unwind under the action of the weight 22, and thereby rotate its wheel 7, which being in mesh with the wheel 38 will transmit itsmotion to the shaft to be driven, the wheel 6 now slipping or rotating in the opposite direction to the drum 3, as did the wheel 7 when said drum 2 was winding up the cable.

In Fig. 2 I have shown a pump-rod (denoted by the letter 1)) for operating the shaft 10. This rod, as shown, is provided with a pawl c, which engages a ratchet-wheel (Z, fixed to said shaft. A stop-ratchet e is employed to prevent retrograde movement of said shaft.

In Fig. 1 I have shown the power as being derived from a rotary source, 9 denoting a rotary shaft for transmitting the movement to the shaft 10. The shaft g is provided with a pinion 72, which is in mesh with the gearwheel 7', secured to the end of the shaft 10. The pinion h is loosely fixed upon the shaft g and is provided with a clutch member h, which is adapted to engage a clutch member 7?, splined to the shaft g. WVhen these two clutch members are locked together,the power from the shaft 9 will be transmitted to the shaft 10. j denotes a stopping device which consists of a lever 76, having one of its ends in the path of movement of the weight 22. A rope l, rove around suitable pulleys m,.connects the opposite end of the lever 7a to a pivoted crank-clutch shipper-lever o. It is evident that when the Weight 22 is elevated and strikes the free end of the lever it will elevate said end and, through the cord or rope 11, disengage the pinion h from gear-wheelt', thus stopping the power if it be supplied to the shaft 10 faster than it can be taken from the shaft 41, and thereby preventing injury to the power-transmitting device, or in the event that the machine to be driven is held in a state of rest or the brake applied to the shaft 41 the power taken on at the shaft 10 will be likewise stopped when the weight 22 strikes the lever 7c. The power-transmitting device will then be in condition for immediate future use for transmitting a uniform power to the machine to be driven.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without requiring an extended explanation.

Various changes in the form, proportion, and details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

1. In a machine of the character described, the combination with suitably journaled drums, of a rope or cable having its ends attached to said drums, aweight supported by said rope, a drive-shaft, and a shaft to be driven, gearing for transmitting motion from the drums in alternation, and means for applying the power to said drums from the driveshaft, in alternation, substantially as set forth.
