HORSE-POWER.

. SPECIFICATION forming part of Letters Patent No. 354,842, dated December 21, 1886. Application filed February 13, 1886. Serial No. 191,895. (No mo'd'el.) Patented in Canada April 15, 1884, No. 19,117.l

To @ZZ whom it may concern:

Be it known that I, CHARLEs SANDEORD, of Fenelon. Falls, in the Province of Ontario, Canada, have invented new and useful Improvements in Horse-Powers, (for which I have obtained a patent in Canada, No. 19,117, bearing date April 15, 1884;) and I do hereby declare that the following is a full, clear, and exact description of the same, reference being 1c had to the accompanying drawings.

Figure 1 is an elevation of my improved horse-power. Fig. 2 is a vertical longitudinal section of the saine on line m cv, Figs. 3 and 4. Fig. 3 is a top view, and Fig. 4is another top View, the crown-Wheel being removed. Fig. 5 is an elevation of the slip-coupling. A A are two sills connected at each endby two ties,B,to form the main frame, which may be supported upon axles C and Wheels D.

E are two central ties secured a little distance apart to the sills A, and connected by pieces E' at each end.

F are corner-pieces secured to the sills A and ties E. Upon these arejournaled the friction-rollers F', supporting the inner dat rim of the crown-wheel.

Two longitudinal shafts, G, are j ournale'd in the center of the main frame A B, the outer end of each journaled upon the ties B, and

3o their inner ends upon the ties E.- Each carries upon its outer end,and between the outer journal-bearings, abevel-pinion, Go, gearing with the crown-wheel, and at their inner end,over hanging the transverse sills E, a bevel-Wheel,

G'. The' shafts G are constructed with a slipcoupling, G",to enable the horses to stop,while the balance-wheels H" exhaust the acquired momentum or inertia.

In the center of the transverse frame E E',

`4o and journaled upon the main sills A and the end pieces, E', are two lineable transverse shafts, H, each carrying at its inner end a bevel-pinion,H',gea1-ing into the bevel-wheels G, and upon its overhanging outer end a'bal- 4 5 ance-wheel, H", the projecting shaft end being square or otherwise prepared for connecting the tread-rod or driving-shaft. A circular dome-shaped flat-topped cap, I, witha trunnion,I', at thetop,is`fitted over the bevel Wheels 5o and pinions G' H', and secured by the feet upon the transverse sills E.

K 'is the crown-wheel. It is constructed with a fiat-topped dome-shapedhub, K", corresponding to the cap I, upon which it is supported and journaled byy means of the trunnion I', the rim K and the hub K being connected by arms K". The rim K is made of sufficient breadth behind the teeth to form a dat surface adapted to run upon the friction-rollers F'. The upper surface of the rim is also made flat 6c and placed under the guide roller J, journaled over the pinions Go to a bridge-piece, B', secured at each end of the main frame, so as to prevent the crown-wheel from ungearing with the bevel-pinion below. A number of brackets, K', are secured upon the crownwheel, these brackets having eyes or holes into which draft poles or sweeps L maybeinsert-ed and footed in the hub K'.

It will be seen that the draft being applied 7o to one or more of the poles or sweeps L, mo tion is given to the crown-wheel K K' K", which communicates the same to the pinions G0, and by the shaft G and bevel-wheel G' to the pinions Hgand the shafts H, from which the power may be taken off.

I claim as my inventionl. The combination, with the main frame composed of the sills A A, ties B B, sills E, ties E', and corner-pieces F, having friction- 8o rollers F', of theshafts G G H H, bevel-gears G H', crown-wheel K, having arms K' and hub K", and brackets K', bevel-pinions GC, guide-rollers J ,cap I, trunnions I', and bridgepiece B', the Whole constructed and operating 8 5 as shown and described, and for the purpose set forth. A

2. The combination of the flat-topped cap I, trunnion I', integral therewith, fiat-topped dome-shaped hub K", bearing upon said cap 9o and journaled upon the trunnion I', crownwheel rim K, arms K', to Which said hub K" is secured, pinions G", shafts G, bevel-wheels G, clutches G", bevel-Wheels H' and shafts H substantially as shown and described.

3. The combination of the shafts G, bevelwheel G', clutch G", bevel-wheel H', shafts H, and cap I, covering said wheels and clutches, substantially as shown and described.
