CASH-CAR.

SPECIFICATION forming part of Letters Patent No. 623,632, dated April 25, 1899.

Application filed March 16, 1898- Serial No. 674,021. (No model.)

To ztl whom it may concern.

Be it known that I, MARVIN V. SHERWOOD, a citizen of the United States, residing at Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Cash-Cars, of which the following is a full, clear, and exact description.

This invention is in that class of caslrcarriers in which the car is adapted to travel upon a substantially horizontal way of wire or other suitable material and in which the said car is caused to travel upon the way by a push of the'hand or by a spring or other suitable propelling mechanism. At or near each end of the said way devices are provided for retaining the car.

The object of my present invention is to provide a car of the class referred to embodying a certain novel construction, hereinafter described, in which a single movement of the operator serves to release said carfrom'its point of retention and also causes it to travel upon its supporting track or way.

To assist in ex lainin m newl -invented b cash-car, the drawings hereto annexed have been provided,illustrating the same as follows:

Figure 1 is an elevation of my said car, and Fig. 2 is an end view thereof. Fig. 3 is a view similar to that of Fig. 1, but is partly broken away to expose the interior construction, said Fig. 3 showing also the position assumed by the car when being started or stopped. Figs. 4 and 5 are sectional views taken, respectively, on lines a; at and y y of Fig. 1.

Referring to the drawings, the letter a indicates the track or wire way upon which my improved form of car is adapted to travel, and said way may be horizontal or may be fixed at any inclination not so great as toprevent the driving of the car from end to end of the way by a single impulse derived from the hand of the opera-tor or from any suitable mechanism.

In this class of cash-carrying devices it has been heretofore a common practice to suspend the car below the way by means of two grooved wheels or trucks mounted upon said way one ahead of the other or to suspend said car by a single wheel only, in which latter case suitable wheels are located below said way, one in front and the other in the rear of the suspension wheel, thus preventing all oscillation of the car in the direction of its travel. My present in vention'aims to provide a car of the last-named type-that is to say, one that is suspended from the way by a single grooved wheel only; butI combine with such a car means consisting of simple and inexpensive mechanism for locking the car when it arrives at either end of the way.

The car of Figs. 1, 2, and 3 is formed of three principal sections 1), c, and d, hinged together midway the length of the car, as at e, and the opposite or free ends of sections 1) c are formed as hooks b c, that are adapted to coact with similar hooks e, that are fixed at the ends of the way a. The extreme ends of the hooks b 0 also serve as buffers, that engage fixtures e at the ends of the way, said fixtures a being preferably of yielding material, as rubber, by means of which the otherwise rigid shock occasioned by the impact of the parts i) c 6 will be cushioned.

Pivoted to the car-sections b care plates ff, whose upper or free ends overlap each other and are. bored to provide journal-bearings for the axle of a grooved wheel g, that is mounted upon the way a and by means of which the complete car is suspended. Within mortises b c in the car-sections b c are journaled grooved wheels h it, that bear against the under side of the way. and being located one ahead and the other behind the suspension-wheel g the car is thus positively prevented from oscillating in the direction in which it is traveling, as will be readily understood by reference to the drawings.

The lower section d, which, as I have briefly explained, is hinged to the meeting ends of the main sections 1) c, is of sufficient weight to hold said main sections normally horizontal, as in Fig. 1. The lower face of section dis formed, as here shown, with an undercut or dovetail opening adapted to receive and retain a removable cash-receptacle t'. The upper face of section d is inclined downward from the center toits ends, as at d, and the ends of said section d are preferably connected with the adjacent ends of sections b c by straps d When it is desired to use my described in Fig. 3, as well as when said sections are in cash-car, the free or hook-shaped end of one of the main sections 1) c is grasped and drawn downward to release it from the fixed hook e, the said main sections meanwhile yielding at their hinge connection, as in Fig. 3, and the wheels h h serving as fulcra, upon which the said sections rock. So soon as the hook is disengaged from its fixed companion the complete car is pushed along the way with suflicient force to cause it to travel to the other end of said way, and the inst-ant the hand of the operator is removed the combined weight of section d and the attached cash-receptacle i drags the inner ends of sections 1) c downward until said ends abut, as in Fig. 1. lhe arrangement of the hinged sections 7) 0, wheels it h, plates ff, and suspension-wheel g is such that the three wheels are at all times in contact with the way a, not only when the several car-sections are in their normal positions, as in Fig. 1, but also when they are swung on the hinge, as in Fig. 3, to disengage the hooks b, c, and 6', this peculiar and desirable result being brought about by the manner of supporting the wheel gthat is to say, by means of the plates ff, which, being loosely pivoted to the car-sections 1) 0, hold the wheels h h in close engagement with the lower side of the way when sections 1) c are rocked into the positions shown their normal horizontal positions, as in Fig. 1, thus effectually preventing all oscillation of the complete structure in the direction of its travel when moving along the way. It should also be noted that while the wheels h h engage the way to prevent oscillation, as above explained, they cannot bear against the said 1 way with suflicient force to retard or in any degree hinder the travel of the car, for the obvious reason that when the hinged car-sections 11 c are in their normal positions, with their inner ends abutting, as in Fig. 1, the said wheels h h are held from too close .or binding contact with the way, yet are in such egagement therewith as to prevent longitudinal oscillation. When the car is traveling along the way, the lower section (Z is held from oscillating by the straps (1 already referred to.

Having thus described my invention, I claim 1. In combination with a suitable track, a car formed of hinged sections substantially as set forth, a single wheel mounted upon said track, and holding said car in suspension, and wheels journaled in the hinged car-sections, in contact with the lower side of the track, and located one in front and the other in the rear of the said suspension-wheel, substantially as specified.

2. In combination, with a suitable track, a car formed of three sections hinged together as set forth, wheels g journaled in said ear and bearing against the lower side of the track, a wheel mounted upon said track between the two lower wheels, and connections between the upper, central, wheel, and the hinged carsections consisting of pivoted plates f, all substantially as specified.

Signed at Stamford, Connecticut, this 28th day of February, 1898.
