FERDINAND E. OANDA, OF NEW YORK, N. Y.

MECHANISM FOR DRIVING HAND-CARS.

QPECIFICATION forming part of Letters Patent No. 34:4,163, dated June 22, 1886.

Serial No. 130,957. (No model.)

To all whom it may concern:

Be it known that I, FERDINAND E. CANDA, of the city, county, and State of New York, have invented a new and Improved Mechanism for Driving Hand-Oars and for otherPurposes, of which the following is a full, clear, and exact description.

My invention relates to the construction of an improved mechanism for driving handcars, and its object is to produce a mechanism by which a car may be driven at an exceedingly high rate of speed by means of the ordinary hand-power employed to propel such cars; and to this end my invention consists of a system or series of links or levers united in the form of a lazy-tongs and arranged to be extended and contracted to impart a rotary movement to the crank-shaft, said movement of the lazy-tongs system being brought about by means of a double-armed hand-lever,which is mounted on a central connecting-bolt of the series of levers and connected by a novel arrangement of links with the outer central joi nts.

of said levers.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an end view of a handcar provided with my improved driving mechanism. Fig. 2 is a side view of the car, with a portion of the supporting-frame removed to show the various parts of the driving mechanism,which in this view are represented in the position they assume on the full downstroke. Fig. 3 shows the position of the parts on the halfstroke, and Fig. 4 on the full upstroke.

The hand-car proper is of the ordinary type, such as is used on the Pennsylvania Railroad, of which the general construction is so well known that it is unnecessary to go into any description thereof. A frame corresponding to the ordinary form of lever-frame, only the frame in this case is slightly higher than usual, and is located directly over the crankshaft A, is formed by four corner-posts, B B, which are fixed to the floor-bean1s and united at their upper ends by a cap, 0, which is hollowed out in pyramidical form and supports a bearing-block, D, A short rod or bolt, E, is mounted in bearings a a, formed in the block D, and this rod carries the four upper links,

I) I) and c c, of the driving mechanism, the links being separated and spaced by washers ii, and the links I) I) being between the links 0 a. Each pair of links. carried by the rod E carries a pair of links, such as those shown at (Z d and c c, the connections being made by means of bolts ff, which are passed through apertures formed in the ends of the links, the links 0 0 being outside of the links Z) I), while the links (I d are inside of or between the links 0 c, the bolts ff carrying washers between the links, as in the case of the rod or bolt E, and it may here be said thatin allcases I prefer to space the links by washers. The links (I d and c c are crossed, the links (1 cl being carried between the links 0 e, and the two sets of links are, as it were, pivotally connected at their centers by what I will call the main connecting-bolt F.

To the extending ends of the links 0 e and (Z d, I connect the lower series of links, H H and h h, by means of bolts 9 g, and the links it h are loosely fixed to the links H H by a bolt, k, the attachment being made at a point so that the distance from tog will be equal to the distance from 7; too. Thelinks H H serve the double office of links in the lazy-tongs system and of connecting-rods between such system and the crank J of the shaft A, which shaft is,as usual,mounted in bearings carried by the floor-beams. The shaft A carries a large geanwhecl, K, which engages with a pinion, N, that is fixed to the axle M of the driv ing-whcels O 0.

Upon the bolt F there are mounted the central arms, Z Z, of the double hand-lever L L, the said central arms being rigidly fixed to or made integral with the outer arms, Z Z, which carry the handles m in.

The arms Z Z are provided with bolts 11, or upon each side of the central bolt, F, said bolts a a being placed at like distances from the central bolt, which distance is equal to onehalf the length of the links 6 and 01. These bolts not carry short links 0 0 and 0 o, respect ively, similar links, 1) p and p 1), being can ricd by the bolts f and g of the lazytongs system. The free ends of the links 0 o and 12 p are connected by a link, g, which is formed with a central lug, to which there is pivotally connected a pair of links, r 9, which reach to and are loosely held by the boltf, while the free ends of the links 0 0' and p p are connected by a second link, 8, which is a duplicate of the link q, being formed with a central lug, s, and connected to the bolt 9 by links r 1".

From the arrangement of connecting parts, as above described and as illustrated in the drawings, it will be seen that the lever L L is connected by means of links to each of the four outer central joints of the power-transmitting mechanism, and that the central bolt of the said power-transmitting mechanism becomes the fulcrum of the lever through which the power is applied, so that the hand-lever follows the general swing of the lazy-tongs system upon its upper supporting-bolt, E, and is consequently always in position to act upon such system through the medium of its connecting-links.

In operating my improved driving mechanism the handles m m of the lever L L are grasped, and if the crank is in the position shown in Fig. 4 the handle m is lowered, which movement will cause the projecting ends of the links 0 0 and p p to rise and the corresponding ends of the links 0 0 and p p to be lowered, thereby driving the links q and s closer to the points a f and n g, respectively; but to bring about this movement of the links q and s the links 1' 7' must also be moved toward the points named, and consequently the points f and f will approach, as will also the points 9 g. In other words, the lazy-tongs system' will be extended and the crank-shaft moved to the position shown in Fig. 2. WVhen the motion of the levers L L is reversed, the movement of the links q and s will also be reversed, and at the half-stroke of the lever the parts will be in the position shown in Fig. 3,

a continued movement carrying the parts to the position shown in Fig. 4,-the movements described and indicated being repeated at each full-stroke of the driving-lever.

With. the system described there is no undue strain on any one of the pivoted joints, as the power is equally distributed; but in some cases it would not be necessary to have all four of the points f f and g 9 connected with the lever L L, as the power could be ap plied to the points ff through the links 0, p, q, and 1'; but I prefer to distribute the power to all four of the connecting-points.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. An improved driving mechanism, consisting of a lazy-tongs system, wherein the powerlever arm is mounted upon and supported by the central pivot or bolt of the system, and con-- nected, by mesne connections, to the outer central joints of the system, substantially as described.

2. An improved driving mechanism, consisting of a lazy-tongs system, wherein the powerlever arm is supported by the central bolt of the system, and connected by links, in a man ner substantially as described, with the four outer central joints of said system, substantially as set forth.

3. The combination, with the crank-shaft and lazy-tongs system, substantially as described, of a lever, L, and links 0, p, q, and r, substantially as set forth.'

4. The combination, with the crank-shaft frame and the lazy-tongs system suspended and held by the bolt E, of a lever, L, links 0,

p, q, and r, and a crank-shaft, substantially as set forth.
