CASH AND' PARCEL CARRYING SYSTEM..

SPECIFICATION forming part of Letters Patent No. 295,172,dated March 18, 1884.

v Application led February (i, E84. (No model.)

To ali.'- wiom t may concern,.- y

Be it known that I, WARREN S. HILL, of Boston, in the county of Sut''olk and State of Massachusetts, have invented a new and useful Improvementin Cash and Parcel Carrying Systems, which improvements are fully set fo rth in the following specification.

My improvement relates to a eash-carrying system wherein is employed a car running on a wire way, and has especial reference to the mechanism employed to stop and retain the car when it has rear-.hed tlleend of its run.

It consists of a buffer and a retaining device secured to the wire way, about which itis disposed axinlly,so that the wire passes through its' center, and a hooked arm or lever pivoted to the ear and held'against a stop by a spring, by means of which it is kept in position to engage with the retaining-flange oft-h e butter, all et' which will be more particularly described hereinafter. i

Referring to the drawings, Figure l reprej sents a side elevation, showing the different parts in position when the car has reached the end oi' its run and is secured to the buffer. Fig. 2 shows the hooked arm made integral with the handle for throwing the oar along the wire, and the stop that keeps itin position to engage with the buffer. Fig. 3 is alongitudinal Vertical section, showing the construction ci' the buffer, and its relation to the wire way and to the parts shown in Fig. 2. Fig. 4 shows another form in which the buffer may be made.

In the drawings, A. represents a ear, the grooved wheels ot' which, da, run on the wire B. O is the butter, through which the wireB passes, and to which is secured the clamp c ci. The @entrai piece of the frame, c', has its ends extended beyond the uprights that carry the grooved wheels, land a 'projection on its upper side, c2, (see Fig. 2.) is grooved to bestride the wire B, and forms what may be termed a butter end,77 n?. As this is the part that strikes theprojeeting end ot' the buffer, a somewhat similar projection extending downward, c3, receives the pivoted arm D, the pivot being shown at d. riihe hooked end d? is shaped so as to readily slide over thebeveled edge of liangef' on the buffer when they come together. The arm D lmay be made integral with the handle di, by which the car is 'thrown along the wire'. A projection, d, on

` the top of the arm D has a bearing on the frame a', as shown at a, against which it is held by a spring, g, thereby forming a stop, by means 'of which the arm D is held in position to engage with the iiange f of the buffer. The spring g is secured to the-stop d and to the frame a at a5. The buffer G is i u two partsone fixed and the other movable. The fixed part c has a lug, c', at its outer end, and a. strap, ci, is secured to it by two screws, only one of which, ci, is shown in the drawings. The wire B is clamped between the lug c and the strap c2, thereby securing the buffer to the wire without danger of injury to the wire, as would be the case were a set-screw employed. The movable part of the buffer,f, is fitted to move on the extended cylindrical part of c. 1t has a fiange, f', which acts as a catch for the hooked arm D.- A groove, f2, receives the pin c4, which limits the outward movement of 'A washer, f3, of leather or other material, 'may be fitted into a recess' in the end of f, to lessen the noise when the parts come together. The buffer spring 7L is placed between the ange c5 ofthe fixed part c and the iiangef of the movable part, and when the ear strikes the buffer its momentum is received by the spring h as the movable part f is pushed toward and onto the fixed part c, and the yielding of the spring brings the ear to a gradual stop, the reaction of the spring bringing the parts again into their normal position.

The operation of my invention is thus (iescribed: As the car A comes toward the but'- `fer C, the hooked arm D is, by means of the stop d and the spring g, held in position so that the inclined surface of the hook d2 strikes the beveled edge of the retaining-tiangef, and by the yielding of spring g slides over it, and the car and buffer become locked together at the instant of contact between the buffer end ofthe car, c2,and the projecting end ofthe buffer, f3, and both move forward together until the inertia of the ear is overcome by the resistance of the buffer-spring h, when the recoil of the spring restores the parts to their normal position again. Theear ispropelled along the wire `B by the handle da, which is pivoted to the car by being made integral with the arm D, and a slight pressure on the handle in the IOO direction the car is to be sent releases the hook d`l from the retaining-flange f', and the car is' easily throi'vn along the wire B.

Having` thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isy 1. Ina cash and parcel carrying system, a car provided with a pivoted hooked arm held against a stop by a spring, and a lbuffer dis posed axilly on the Wire way` consist-ing of a xrd part secured to the Wire7 and a yielding pait moving against aspring, and having a retaining-flange t'o engage with the pivoted` hooked arm, substantially as set forth.

2. In a buffer for a cash-carrying system, the combination ofthe fixed part c, with lugv c', strap cscrcws c3', and pin c, and the movable partf, with retaining-Heilige f, slot f2, washer f3, and the spring ll,"substantially as shown and described.

3. In a cash-carrying car7 the combination of the handle d, made integral with the pivoted hooked arm D, the stop d, spring` g, and frame a,substantially as shown and described.

In testimony that I claim the foregoing; as my ovvli invention I hereunto affix niy signature in presence of two witnesses.
