MOTOR.

SPECIFICATION forming part of Letters Patent No. 440,913, dated November 18, 1890.

Application filed August 7, 1890.

To @ZZ whom. it mag/'concern' Be it known that I, GEORGE H. CHAPrnLL, a citizen of the United Stat-es, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Motors, of which the following is a specification.

Figure l is a side view of my improved Spring-motor. Fig. 2 is an end view of the same. Fig. 3 is an enlarged side view of the tripping device; Fig. 4, a top view of the same; and Fig. 5, a cross-section of the mechanism through line c of Fig. 1, with portion of the disk cut away, showing the arrangement of the mechanism.

The object of my invention is to provide a spring-motor so constructed and arranged that while in the process of winding up the spring or springs the same amount of force will be exerted on the driven mechanism. It also provides a series of spring-motors arranged on the same shaft, whereby the iirst of the series can be employed to drive the mechanism and at the proper time the second of the series will be thrown into the gear and the rst released, and so on. Inversely, in the process of winding, the same crank or other means for winding can be used to wind up the entire series, winding up each in succession, and each being so arranged that when one is wound the one next following will be wound up, and so on. It is found to be impracticable to employ the tension of a single spring to operate mechanism for any great period of time. Several springs in a train or series will produce better results, provided they are so arranged as to work successively by the action of the mechanism itself; and it is essential that such a train of mechanism to be a practical and commercial success should be made as simple and cheap as possible. My mechanism for this purpose provides a single shaft or arbor on which I place the entire seriesof springs and gearing, each of which, while entirely independent of the others in its action, is nevertheless dependent on the one next to it, so far as the time of its action is concerned.

Referring now to the accompanying drawings, the frame of the mechanism 1s shown as composed of the two end standards AA, pro- Serial No. 361,352. (No model.)

vided with a horizontal beam B near the base and a bar O at the upper end.

D represents the arbor or shaft for the spring journaled in the standards midway, and E is a line-shaft to which power is imparted from the spring mechanism. One'end of the arbor D has a crank F for winding the springs; but instead of the crank other means may be employed for that purpose.

The arbor D is designed to carry a series of springs and gear-wlieels, and as they are duplicates of each other a description of one will be sufficient for all. In Fig. l I show one of the series with the main gear-wheel in section and having a spring attached, while in the other the main gear-wheel is shown without an accompanying spring. This main gear-wheel G has external teeth I-I`,which mesh with the teeth of the gear I on the liiie-shaft E. The wheel G has also ratchet-teeth .I externally and internally the teeth K. The gear G is placed loosely on the shaft D, and on thatside of the gear having the internal teeth K a barrel L is placed loosely on the shaft. This barrel has a disk M facing the gear G. Between the gear G and the disk M a pinion N is secured to the shaft D by means of the key O, or otherwise, and intermediate between the pinion N and internal gear K is a small pinion P. Iprefer to have one of these pinions P on each side of the central pinion, as shown in Fig. 5, and these small pinions are journaled to the pins Q, which project from the inner face of the disk M. It will thus be seen that while the central pinion N turns with the shaft D the barrel L and gear G are loose on the shaft and operated only through the medium of the pinionsNP. On the inner face of the disk M near the teeth .I is a pawl R, hinged thereto, which engages with the ratchet-teeth J. A spring S, attached to the barrel L and wound around the same, has its opposite end attached to the bar O of the frame.

The gear I on the line-sliaft E is placed loosely thereon, and the hub thereof is provided on one side with a toothed clutch T, while on the opposite side of the gear is a spring around the shaft, which acts between the gear and a suitable collar on the shaft so as to keep the gear in engagement with the IOC toothed clutch when turned in one direction, but at the same time will permit the gear to reverse or turn in the opposite direction independently of the shaft E. Any form of clutch maybeusedforthispurpose; butIhavemerely indicated this form in order to show the manner of operating the device when a series of springs and gears are employed.

A train of the gears, disks, and springs is placed on the arbor; but I have herein shown only two sets of gears and disks, the spring being removed from the second set.

In order to be able to throw the successive springs and gears into action,I have devised an automatic tripping` device, which consists of the wheel V, having, as shown in Fig. 4, the eight points or spurs W. This is journaled to the beam B of the frame. Attached to its spindle and beneath the wheel V is a small pinion X. A bar Y, having one of its ends bent upwardly,so as to engage with the teeth H of the gear G, is provided on one side with suitable teeth to engage with the pinion X and is confined in suitable housings or guides, so as to permit the bar to run back and forth as the wheel V is turned. A spur or pin Z, attached to the periphery of the disk M, engages with the teeth W of the wheel V, and causes the latter to rotate the distance of one tooth at each rotation of the disk M.

The operation of the invention .is as follows: We will suppose that the spring S is completely unwound and it is desired to wind up the mechanism. The crank F is brought into requisition, turning the shaftD to the left, thus moving the pinion N in the direction shown by the arrow. The .eifect of this is to turn the pinions P to the right, as shown, and since the latter are attached to the barrel-disk M the latter turns to the Lleft, thus winding up the spring S. At the same time, the gear G being in engagement with the gear I, there is no change in motion imparted to the gear G, since the action of winding by the crank releases the pawl R, which travels back over the ratchetteeth .I and engages again the moment the crank is released. Vhen the force of the first spring is exhausted, the 'wheel V having meanwhile been rotated by the action of the spur Z, the bar Y becomes disengaged from the teeth of the wheel G inthe next series, causing the spring in that system to operate. The force is then imparted by the second gear G on the arbor D to the second gear I on the line-shaft E, so that while the first gear is still in engagement with the gear G and the latter is still in motion it is necessary to prevent the gear I from turning or acting on the irst spring. This is accomplished by attaching the clutch T, as shown. It is obvious that this same system may be employed with equal facility with weights instead of springs, and for some purposes weights are preferable.

One of the important features of this in-A vention is its adaptability to use one or more springs at the same time. If it is constructed with a large number of springs in the train, an immense power can be exerted by throwing on the entire series, or only one or two can be used; or, instead of throwing on each spring in succession, the same mechanism can be adapted to throw on two sets of springs at the same time, or more, all of which can be accomplished without departing from the spirit of my invention.
