TREAD OR RAILWAY HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 231,656, dated August 31, 1880.

Application filed January 9, 188d.

To all whom it may concern:

Be it known that I, PETER. K. DEDERICK,

York, have invented certain Improvements in Tread or Railway Horse-Powers, of which the following is a specification.

My invention consists in improvements on were granted me May 13, 1879, No. 215,214 and No. 215,213, and relates to the construction of the power so as to adapt it to four horses working two abreast, and also to the tion of the power.

Figure 1 is a perspective view of my improved power. Fig. 2 is a sectional view representing my improved governor or regulator. Fig. 3 is also a sectional view representing safety appliance on the power-shaft.

Similar letters represent similar parts.

A represents the frame or support of the power, which may be constructed in any suitable manner.

B represents the endless platform on which the horses walk, which, having been fully departicularlydescribed herein. Said shaft is represented by dotted lines in Fig. 1 and in (l is the powershaft, which passes through the endless platform and connects to it di- Dis a second power-shaft, geared to the first shaft to increase the motion, and they may be used either singly or together, constituting single and double gear in a manner usual in this class of powers.

E is the band-wheel located on and secured to the power-shaft D.

His a collar secured on the end of the powershaft.

I is a spool loosely mounted on the powershaft and provided with a friction-flange, K.

L is a corresponding friction-flange, also mounted on the power-shaft, which is provided with a feather, so that it must turn with the shaft, but may move on the shaft in the direction of its length.

M Mare toggles, the one end of which is pivoted to the plate L and the other end at,

. wheel.

to, or near the band wheel hub.

N N are rods pivoted to the joint of the toggles, and extending outward and passing loosely into sockets O 0, and provided with springs P P to bear the rods and toggles inward.

R B are balls or weights located on the rods N and secured with nuts, which may be adjusted outward or inward, as desired, to give, more or less force.

S is a brake-lever, which may be of any ordinary form, pivoted at one end and provided with a shoe or friction-surface, T, which may be brought to bear on the face of the band- A spring of wire, plate, or rubber, as a, may be used to hold the brake off when not re-. quired to bear. A strap or cord, V, connects the spool I to the brake-lever S, or to the stud W, secured to the lever. A rack in place of the strap and pinion in place of the spool would have the same effect, but would be more expensive.

X is a brake-slide of ordinary pattern, provided with a rollerto act as a tightener on the belt, and a bracket or shoulder to bear against the lever S, and pivoted at the end, as shown, so that when the belt is cast the slide-bar will .fall and apply the brake. This is, however, a no part of the governor, and is unnecessary 80 unless, from some cause, the governor fails to act.

2 represents a friction-wheel applied to the power-shaft O, with a strap, 3, adapted to bear on its surface, and which is operated" by the lever 4. This is of use only as a safety appliance when the gearing connecting with the band-wheel shaft becomes detached or broken, and when without this safety appliance there is nothing to stop the power, and in such cases usually runs the horses 0E back and frequently injures them severely.

Y-is a cross-bar passing between the horses across the power, so that two horses are in frontand two back of it, and to this cross-bar the length partitions may be secured. This crossbar is essential to prevent the horses from walking up too far or falling back, and thus becoming excited and injuring each other or crowding each other ofi' endwise. A. strong plank might be passed the entire length of the power between both pairs of horses and se cured to the forward and rear cross-bars, which would take the place of the two length-partition strips, and then the cross-partition might be secured to this length-partition instead of to the sides of the power with the same effect, as shown but thecross center partition is indispensable for safety.

In operation the frame is elevated at the forward end to secure the required power, and then the horses are led on the power one at a time, and the two forward horses first. The cross-partition Yis now secured across the center of the power and the upper length-partition also secured in place. The two rear horses are now led on and secured by means of the rear bar and partition, which is secured to the crossbar Y at one end. The band may now be applied to the work and the power started. The governor-weights R R having'beenpreviously set and secured and the springs P P brought to the proper tension so that the weights will not move outward untilthe speed is too fast, the governor does not act so long as the motion does not exceed that required; but as soon as it becomes too fast or the belt cast, then the increased motion throws the weights It R outward against the resistance of the springs P P and causes the toggle M to press the friction'plate L against the friction-surface of the spool, and thereby cause the spool to be rotated-and the brake-strap to be wound thereupon, and thus apply the brake and check the speed of the power; but when the speed-is reduced again to the proper limit the springs P P overcome and force back the weights R R and the brake falls back from the wheel; or, if the power is so great as to keep up the speed to more than required, the brake is then held on continuously with sufficient force to just hold the speed as required.

It should be observed that the motion may be varied to suit by moving the weights outward and inward also, by adjusting the springs, either on the rods or brake-lever, or by adjustments on all these devices at once, if required.

Having thus fully described my invention, what 1 claim, and desire to secure by Letters Patent, is as follows:

1. The combination of the endless platform with the frame and cross-partition, constructed substantially as described, so as to work four horses, two abreast and two in the rear, as set forth. Y

2. The combination of the cross-partitionY with the length partitions, substantially as and for the purpose set forth.

3. In combination with the band-wheel of a horse-power, the weighted rods N N, with the springs PP and toggles MM, for the purpose set forth.

4. The combination of the brake-lever S, the spring for holding the brake normally ofi' of the band-wheel, the loose friction-spool on the power-shaft D', connected to the brake-lever by the strap V, and the devices for revolving the spool by frictional contact and causing it to apply the brake, substantially as described.

5.. The combination, with the brake-lever, its spring, and the strap connecting said lever to the friction-spool of the governor, of the brake-slide and its tightening-roller, substantially as described, for the purpose specified.
