VJOHN VALENTiNE,
Improvement in Horse Power o. n9,954 Jail: Ptnted0ct,17,1871.@
UNITED STATES PATENT OFFIG.
JOHN VALENTINE, OF BUFFALO, NEW YORK.
IMPROVEMENT lN HORSE-POWERS.
Specification forming part of Letters Patent No. 119,954, dated October 17, 1871.
To all whom it may concern:
Be it known that I, JOHN VALENTINE, of the city of Buffalo, in the county of Erie and State of New York, have invented a certain Improvement in Horse-Powers, of which the following is a specification My improvement relates to that class of horsepowers in which a stationary toothed rim is fastened to the bed of the machine, above which is arranged the rotating frame provided with a pinion which engages with the said rim and transmits, through suitable gear, motion to a central vertical shaft. This toothed driving-rim has usually been secured, by bolts, directly to the wooden bed pieces of the machine. The yielding character of the wood permits these bed pieces to springunder a sudden strain, which movement, being communicated to the toothed rim, causes the same to bind with the pinion that engages therewith. My invention consists: First, in the combination, with the central shaft of a horsepower, of the driving toothed rim cast with hublike projections and a cast-iron bridge-tree, the arms of which are formed with sockets to receive the ends of the hubs of the driving-rim. Second, in the arrangement, with the toothed rim, bridgetree, and bed of the machine, of a bolt which firmly secures the said parts together.
In the accompanying drawing, Figure I is a sectional elevation, and Fig. II a plan of my improvement inverted.
Like letters of reference designate like parts in each of the figures.
A is the spur-rim a a, a series of hubs cast with and projecting downward from the under side of the rim. They are preferably made hollow, as shown in the drawing. B is the bridgetree, cast with four arms, Fig. II, the ends of which, 011 their upper side, are formed with sockets b to receive the ends of the hubs a, as represented in Fig. I. O O are the two pieces whichconstitute the bed of the machine, on which rest the ends of thebridge-tree, and to which the rim A and the latter are firmly secured by bolts 1) that pass through the rim, hubs, ends of the bridge-tree, and bed pieces 0 O ofthemachine, as clearly shown in Fig. I. E is a pinion, and F a spur-wheel, bot-h mounted on the same shaft and supported in the rotating frame, the pinion gearing with the rim A and the wheel F meshing with a pinion, G, on the central shaft H. This shaft has its lower bearing in the bridge-tree and its upper one in a suitable cross piece within the rim A. The bridgetree and rim A being of cast-iron and firmly secured together the bearings for the central shaft are thereby rigidly held in the same relative position, While the bridge-tree, by connect- JOHN J. BONNER. (159)
