ELECTRlCALLY-PROP'ELLED VEHICLE.
SPECIFICATION forming part of Letters Patent No. 417,259, dated December 17, 18189.
Application filed May 23, 1889. Serial No. 311,811. (No model.)
whereby the loading and unloading of storage'batteries thereupon and therefrom may be rendered expeditious and easy.
Storage-batteries being bulky and heavy, difficulty has been experienced in replacing them when exhausted without either an undesirable delay and waste of time or the assistance of a considerable force of employs.
My invention makes it possible for two persons to operate a charging-station for a large number of cars with expedition; and it consists in certain apparatus and features of construction which may be more readily described in connection with the drawings forming part of the specification, in which.
Figure l is an end View of a car and battery-trucks, partly in section. Fig. 2 is a side view of the same. Fig. 3 is a sectional view on the line 3 3, Fig. 1. Fig. 4 is a section of the battery-supporting tray on a large scale, and Fig. 5 represents on an enlarged scale a part of the apparatus for moving the batteries to and from the car.
The car A is of usual construction, and has beneath its seats B the usual spaces for the reception of the batteries D.
Hitherto it has been usual to take the batteries from the car singly or in small groups-- a process requiring too much time. That all the batteries of one set may be removed at once, I provide the car with a movable panel G, extending lengthwise of the battery-spaces. I connect the several battery-cells of the set to this panel, preferably by means of a false bottom or tray E, upon which the ,batteries rest, and through suitable slots in which pass rollers F, j ournaled upon the tray, and which support the weight of the batteries and roll upon the floor of the car. The panel G is at tached to the tray E, and when the panel is removed from the car the batteries and tray are carried with it.
In order that the tray E may enter the car, it is provided with slots 6, (see Fig. 3 which receive the st-anchions b, supporting the seats and upper frame-work.
I desire to call particular attention to the advantages of connecting the battery-cells with the removable panel. It dispenses with the inconvenient necessity of opening a door in order to gain access to the batteries. Such a door would also be in the way when in its open posit-ion. It also makes it possible to remove and replace the entire set of cells at once, securing a saving of time. vantages result from the connection of the cells with the removable panel and do not depend upon any particular form of that connection. I do not, therefore, limit myself to such a connection made by the use of a tray, but intend to include all constructions in which the batteries are connected with the removable panel, so as to be drawn out from the car with it. Other connections may be substituted for the false bottom or tray. So, too, the tray maybe made in several sections as well as in a single piece.
To receive the batteries when taken from the car and to support them when presented to the car, I provide a platform H, preferably of the same height as the floor of the car and extending lengthwise of the car and in close proximity thereto when the car is in its position for exchanging batteries.
As a means for readily moving the panel and batteries and tray E to and from the car, I preferably adjust to this platform two or more endless chains 1, each of the chains running over sprocket-wheels 2'. Two of these wheels 1' are provided with cranks I, and are preferably mounted upon acrank-rod J, running the length of the platform and journaled in it. As many of these chains and sets of sprocket-wheels may be employed as are desired. I find that two sets-one at each end of the platformare sui'iicient.
utilize these chains as a means for moving the batteries to and fro, any convenient devices for forming a temporary connection between them aud the panel G or tray E may These ad- In order to be employed. One form of such connections of the many which might be devised, and which would constitute an equivalent of mine, consists of a stringer K, extending from end to end of the platform and attached at each end in any convenient manner, as by a bolt 70, to the chains 1. This stringer is preferably of angle-iron of the shape shown, but may be of any other suitable form or material. This stringer rests upon the platform, and is moved to and fro by the movement of the chains, and the latter are in turn moved by the rotation of the crank-arms. The inner face of the stringer K is shaped to fit the outer edge of the panel G, so that when the chain moves toward the car the tray will be pushed by the stringer in that direction. A bearing for applying power to the tray is thus afforded along its entire length, and the tray can be made lighter than would be possible if the strain were applied at several points only as, for instance, at each end.
To provide a connection between the panel or the tray and the chains, whereby the latter may be utilized in withdrawing the bat teries from the car, temporary connections are provided, which may be of any suitable construction, the form shown herein consisting of interlocking catches L, projecting from the tray or panel, and catches 1, attached to the stringer K. Catches Z are preferably mounted upon a shaft N, journaled in webs 'a of the stringer, the shaft being provided with a handle N, by means of which all the catchesl may be raised out of engagement with the catches L. Openings at: are provided in the rear upright portion of the stringer K to permit the entrance of catches L. The inner ends of the catches L may be supported in a re-enforcing angle-iron 0. It will be noticed that the connection between the catches L and Z is effected automatically on pushing the stringer up against the side of the car while the disconnection is effected by a slight rotation of the shaft N through pressure on the handleN. All, then, that is required in order to transfer a set of batteries from the platform, to the car, or from the car to the platform, is to make the proper connection between the stringer and the panel or tray and rotate the crank-shaft in the proper direction, which is quickly and readily accomplished by two men.
As the car while the process of exchanging batteries is proceeding is without means of independent locomotion, it is desirable to provide convenient apparatus for moving away the exhausted batteries and bringing up charged batteries, and to this end I prefer to mount the platform H upon trucks or rollers O, and to provide tramways P alongside of the car-traclgupon which they may be readily pushed by one or two men. I do not confine myself to this means of moving the platforms H to and from. a position in proximity to the car, as other devicessuch as traveling chains or beltsmigh t readily be d evised which would to a certain extent be equivalents of the means described. The exhausted batteries having been drawn out of the car and placed upon the platform, the latter will be rolled away to a position in which the charging-wires are accessible. A truck loaded with freshly-charged batteries will be rolled up. These will be transferred to the car and the latter will proceed upon its trip. It will of course be necessary to have a number of the trays E and panels G interchangeable with the several cars of the system, so that those which are taken out of each car with the exhausted batteries may be returned to another car with the same batteries when charged. It will be desirable to recharge the exhausted batteries while in position upon their trucks and without removing them from the trucks, though these features are not essential to the system.
My invention further includes a novel arrangement of charging-wires, consisting of conductors Q R S, preferably suspended from the ceiling and supporting trolleys T, rolling on these conductors, to which are in turn attached depending wires (1 '7' s. This form of conductor, with trolley rolling thereon, permits the charging-wires to be shifted from point to point and thus brought near the set of batteries to be charged. The conductors Q R S preferably run in the direction of and immediately over the tramways P.
\Vhile I have shown the charging-wires arranged in sets of three, no particular number is requisite. I prefer to use as many as three, one of them being a common return-wire and the other two differing in potential. With such connections the batteries may be charged to greater advantage than when thereis but one charging-circu it, the circuit of lower potential being first used and the circuit of higher potential being resorted to when the batteries have acquired a considerable potential by reason of their charge, which has to'be overcome. Otherwise it would be necessary to use a resistance in circuit during the first part of the charging operations to reduce the potential of the charging-current or to divide the battery into sections to receive the latter part of the charge, either of which methods is wasteful.
Three or more grades of potential as well as two may be used, if desired.
The several improvements shown herein may be used together as parts of a single system or separately as parts of other systems.
