SPECIFICATION forming part of Letters Patent No. 560,344, dated May 19, 1896.

Application filed September 25, 189,5. Serial No. 563,615. (No model.)

To LZZ whom, t nung concern:

Be it known that I, JAMES WILSON CLARK, of Janesville, in the county of Rock and State of \Visconsin, have invented new and useful Improvements in Cars for Cash-Carriers; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying` drawings, and to the letters of reference marked thereon, which form a part of this speciiication.

4The object of my invention is to provide a car for a store-service apparatus Which shall embody to a greater degree than any other corresponding device yet produced the following points of value: that it shall be, rst, more compact and ornate in form; second, more simple and inexpensive of construction; third, more perfect in its adjustment, relative to the inclination of the track or Wire upon which the car travels; fourth, friction shall be reduced to such a minimum as to be almost eliminated; fifth, oscillation overcome; sixth, the traveling capacity greatly increased relative to the projectile force; seventh, noiseless; by reason of all which a caris produced which can be more generally used than any of the other existing devices for a like purpose.

Heretofore cars for a store-service system have been constructed having a running-gear, consisting` of two, three, or four wheels, the bearings of which are plain axles. So many axles not only produce a great deal of friction, the tendency of which is to lessen the traveling capacity of the car, but to make them smooth, accurate, and perfect, as they must necessarily be, also to turn and face the wheels properly, multiplies the labor and expense of production of such a car. To overcome these objections is one object of my invention.

Having thus described the purpose of my invention, I now proceed to describe my device in detail and demonstrate the several points of superiority, reference being made to the accompanying drawings, and to the iigures and letters of reference marked thereon, which form a part of this speciiication.

In the drawings, Figure lis an elevation in perspective view. Fig. 2 is a section through the longitudinal axis ofthe Wheel or on line a'. fr.' Fig. 3 is a section through the middle circumference of the Wheel A.v

The line x x also represents the line of gravity of my device.

The same letters refer to identical parts throughout the several views.

The dash-pot herein referred to is fully described in Letters Patent granted to me dated August 27, 1895, numbered 545,152.

My device is made compact in form by the use of one Wheel only, A, which constitutes the running-gear thereof.

The receptacle B is suspended to said Wheel by means of the upwardly-projecting arms C C, which terminate at their lower end in a receiver D, in which is placed the receptacle B and its contents. This construction produces a symmetry of outline which cannot be obtained in any other form of construction, and thereby produces a car more ornate in appearance than has heretofore been produced.

My device is less expensive of construction by reason of having but one Wheel, it being a matter of considerable expense to fit the bearings of Wheels for the mechanism in question. I reduce this expense to a minimum by having the smallest possible number of Wheels. It is sometimes necessary to incline the wire on which the car travels by reason of the elevation of the cashiers desk. Therefore I provide a car which is more nearly perfect in its adjustment relative to the inclination of the supporting-Wire, by reason of the easy tilting of the tube or dash-pot, which adjustment is effected as follows:

In the upwardly-projecting arm C C, which carries Wheel A, I provide a circular hollowed seat with beveled edges which receives two outwardly-projecting truncated-cone-shaped projections F F, attached rigidly to the periphery of the dash-pot E, which dash-pot passes between said arms C C at a slight distance below the periphery of the Wheel A.

Said projections F F iit loosely in the seats provided therefor in the frame C C, by which arrangement the dash-pot E may be tilted to conform to any possible inclination of the Wire on which the car travels, and when so adjusted is secured in position by screwing the set-screw G through the seat in said arm,

IOO

so that the inner end thereof im pin ges against the truncated face of the pivotal bearing F sufficiently to secure the same in the position desired.

I reduce friction to a minimum by forming a chamber in the ends of the hubs of the wheel A and introducing therein the balls II. The circumference of said chamber rests upon said balls, which in turn rest upon the axle I, which axle is a screw passing through the ends of the frame or arms C C. By this construction a ball-bearing is obtained for the wheel A or running-gear of my device, and by thus reducing friction the force of gravity, which tends to hold the car plumb, is interfered with in the smallest possible degree.

I obviate oscillation by providing, supple# mental to said ball-bearings, in the ends of the dash-pot E, which extends parallel with and close to the Wire, a hardened notch J or a suitable equivalent, which, when there is a tendency to oscillation, touches the wire and restores the equilibrium of the car. The car being so accurately balanced upon the ballbearing aforesaid maintains its equilibrium by force of gravity almost wholly.

I increase the traveling capacity of my car relative to the projectile force over that of other cars by reducing the points of friction, .in that I use but one wheel in the bearings of which friction is developed, and in so far as I have only half, one-third, or one-quarter as many wheels in the running-gear of my car as there is in any other I reduce friction in the same proportion.

My car is noiseless, in so far as there is no friction to produce a grating or rasping sound, and, in fact, in the operation of my car there is no sound other than the vibration of the tight wire upon which the car travels.

To provide means for projecting my ear, so that it may be operated upon any of the various systems of Wire tracks new in use, I extend the upper portion of the material forming the pivot F, so that it forms the upwardlyprojecting bumpers K, which receive the projecting force or push from any of the devices now in use for this purpose. The receiver D, which holds the receptacle to contain the permit the supporting-lugs of said cup to pass through, and when so passed through the cup is turned to permit said lugs to rest upon the upper face of said ring. The pivots F F and bumpers K, being formed together, are rigidly attached to the dash-pet E by screws, solder, or any of the ordinarymethods of uniting metals.

My device boing capable of adaptation to any of the wire systems of store-service apparatus now commonly in use is more particularly intended to be used upon a wire having such termin al attachments, receiving, projecting, ,and adjusting mechanism as that shown and described in the aforesaid Letters Patent to me.

Having thus described my invention, what I claim as new, and desire to secure by Letters Iatent, is-

1. In a store-service apparatus, the combination of a wheeled carrier With a dash-pot secured to said carrier so as to be adjustable to the inclination of the Wire on which the carrier travels, substantially as described.

2. In a store-service apparatus, the combination with a carrier having a single Awheel of a dash-pot adj ustably secured to said carrier and provided with means to prevent oscillation as the carrier travels'on the way, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
