CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 409,125, dated August 13, 1889. Application filed Octoher 15, 1888. Serial No. 288,084. (No model.)

To all whom it may concern.-

Be it known that I, MOsEs C. SWEZEY, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Cash-Railway Apparatus; and

I do hereby declare the following,when taken in connection with accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact description of to the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a side view of a portion of the track near one station, with the car thereon as approaching the station; Fig. 2, the same as Fig. 1 with the car brought to a stop at the station; Fig. 3, a top view of the car, showing the three wheels; Fig. 4:, an end view of the car. Fig. 5 is a modification.

This invention relates to an improvement in what is commonly called a cash-railway apparatus-that is to say, a railway arranged in storesthe cars of which travel from diiferent points in the store to a central cashier as a means for carrying cash back and forth, and particularly to that construction of such an apparatus in which the track is a wire drawn taut and from which a car is suspended, the wheels of the car running above the wire. The propulsion of the car from 0 place to place is produced by a push given to the car from the startingpoint sufficient to carry it to its destination. It is desirable that the cessation of the movement of the car as it reaches its termination should be easy, 3 5 so as to produce substantially no concussion. My invention has for its object to accomplish this easy stoppage of the car; and it consists in an enlargement of the transverse vertical area of the wire or track near the point 40 of its destination, combined with a car suspended below the track and carried by two wheels resting upon the track above, with a third wheel intermediate between the said two wheels and below the track, ordinarily with- 4 5 out substantial contact with the track, but so that as the car approaches the portion of enlarged transverse area it will bring the third or intermediate wheel into forcible bearing upon the track, and so as to produce a friction sufficient to gradually arrest the move ment of the car.

A represents the track, which is made, as usual, from wire drawn taut between the two stations wit-h which it is desired to communicate.

Near the respective stations the wire or track is gradually enlarged, as represented at B, Fig. 1. This enlargement may be made 'in various ways, preferably by a gradual increase in diameter of the wire. This feature of the track is shown in Patent No. 398,356, granted to me February 19, 1889. Its construction in this application is therefore immaterial further than to say that the enlargement or increase of diameter must be in a vertical plane, it not being essential that it shall be of greater width horizontally than the diameter of the main wire.

C represents the car, which is of usual construction, and is carried by two wheels D D, arranged upon the wire above, and so that the car is suspended from the wheels and hangs below the track.

E represents the third or intermediate wheel, which is arranged upon suitable bear ing-blocks G in the carriage below the track. The wheels D D are grooved, and preferably the wheel E is grooved in like manner; but the relative position of the three wheels is such that normally the wheel E runs below thewire without substantialcontacttherewith, as indicated in Fig. 4, but so that the wire A may lie in a straight line below the wheels D and above the wheel E. The bearingblocks G for the wheel E are provided with longitudinal slots F, and the axle Gr rests in said slots, leaving the wheel free to revolve, but so that the axle may roll along the slot F toward either of the wheels D.

The operation of the wheel E is as follows: Suppose the car in Fig. 1 to be coming from the right and as about to run upon the enlarged portion 13 of the wire. As it passes onto the enlarged portion of the wire the forward wheel will rise as the diameter increases. 9 5 This will bring the third wheel E to a bearing on the under side of the wire, which will cause the wheel to run along the slots in the bearing-blocks, and-as the rise of the forward wheel continues the wheel E also rises and produces a bend in the track, as indicated in Fig, 2, and that bend becomes shorter as the wheel E approaches the rear wheel of the car, as seen in Fig. 2, thus creating such a friction upon the car as to bring it to a stop; but because the rise of the forward wheel D is gradual the stop is correspondingly gradual.

Having stopped at the proper position, the ear is ready to be returned, and such return is produced by giving an impulse to the car to force it toward the left. Under such movement the wheel E rolls along its longitudinal bearings away from the then forward wheel and until it reaches the main wire or track, where it is free, and the car will continue its advance movement until it approaches the station at the opposite end, where a like eulargeinent of the track will produce the same result, but causing the third wheel E to approach the then rear wheel as it did the other wheel when moving to the left.

I have described the wire as being made of a larger transverse area, gradually expanding from the main track toward the station, and this I prefer; but it will be understood to be understood as including such a construction of the wire as will produce the same result.

I claim- In cash-carrier apparatus, the combination of awire track having a gradually-increasin g a transverse area as it approaches its termination, with a car having wheels above the track, a wheel below the track, and bearings for the axle of thelatter Wheel, provided with longitudinal slots, all substantially as described.

MOSES C. SWEZEY.
