SPECIFICATION forming part of Letters Patent No. 413,742, dated October 29, 1889. Application filed March 29, I889- $erial No. 305,285 (No model.)
To all whom it may concern:
Be it known that I, IRA E. STUMP, a citizen of the United States, residing at Richville, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Hand-Cars, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in hand-cars.
The object of the invention is to construct a hand-car wherein shall be combined simplicity and strength, and the arrangement of the actuating mechanism for attaining great speed.
To this end the invention consists in the peculiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter described.
Figure 1 is a bottom plan of my improved hand-car. Fig. 2 is a central vertical longitudinal sect-ion of the same on the line as m, Fig. 1. Fig. 3 is a vertical cross-section on the line 2 z, Fig. 2. Fig. 4 is a similar View on the line y y, Fig. 1. h
In the accompanying drawings, which form a part of this specification, A represents a hand-car body of any suitable construction, and which is mounted upon the axles B 0, each of which is provided with the wheels D.
E represents a stub-shaft, which projects below the floor of the car, as shown, and upon this stub shaft is properly journaled the crown-wheel F, which in the operation of the device engages with the spur-wheel G, secured upon the axle B.
H represents guide-bars secured to the under side of the car-frame, and the ends of the bars maybe extended, so as to form additional hand-holds, if desired, for lifting the car from the track. Between these guidebars the cross-head I reciprocates.
J is a connecting-rod which connects the cross-head I with the crank-wrist K of the crown-wheel F.
L represents the operating-lever, which is fulcrumed in the bifurcated standard M, rising from the car-body, the short arm of such lever being connected by means of a link N to the outer end of the cross-head.
The crown-wheel is provided with a heavy flange a, which in the operation of the car serves as a fiy-wheel, and by its momentum it will prevent the sudden diminution of speed and will materially assist the wheel in passing dead-centers.
By this construction and arrangement of parts it will readily be seen that by raising and depressing the operating-lever L the cross-head I will be compelled to reciprocate in its guides, and by the connections herein described the crown-wheel must necessarily rotate and communicate its motion to the spurwheel upon the axle B of the car, thus causing the latter to move forward upon the track. It will also be observed that the top of the car is left practically free to receive tools or other freight that is usually used and employed by section-hands in repairing track.
What I claim as my invention is- In a hand-car, and in combination with one of the axles thereof, thewspur-wheel G, crownwheel F, having the flange a, the connecting rod J, cross-head I, link N, and actuating-lever L, the parts being arranged and operating in the manner and for the purpose set forth.
In testimony whereof I affix my signature, in presence of two witnesses, this 26th day of January, 1889.
IRA E. STUMP.
