CASH AND PARCEL CARRlER FOR STORE-SERVICE.

SPECIFICATION part of Letters Patent No. 337,809, dated March 16, 1886.

Application filed November 18,1885. Serial No. 183,946. (No model.)

To all whom it may concern.-

Be it known that we, EUGENE I. BLOUNT, of Cambridge, in the county of Middlesex, and CHARLES A. KIMPTON, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain Improvements in Cash and 'Parcel Transmitting Apparatus for Store- Service, &c., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view representing an inclined single-rail track with our improved carrier-elevator applied thereto. Fig.

I 5 2 is a front elevation of the elevator with the carrier thereon, ready to be raised upon the track. Fig. 3 is a front elevation representing the elevator raised with the carrier thereon in a position to be located on the track,

the movable track-section being swung up by the carrier. Fig. 4 is an end elevation. Fig. 5 is a horizontal section on the line as xof Fig. 1, showing only the parts intersected by the cutting-plane and those immediately below it; Figs. 6 and '7, details of the track and tracksection; Figs. 8 and 9, a modification.

The leading feature of our present invention consists in two coacting elements-via, a carrier-elevator and a movable track-sec 3O tiO swu g 1 p thereby or by a carrier thereon, to permit of the location upon the track of each carrier from the station to which it belongs, the return of the track-section into its normal position in line with the track be- 35, mg promptly insured by gravity accelerated or not by a spring, in order that the track may be continuously closed for the passage thereover-of other carriers to their respective stations, each carrierbeingprcferably accelerated 40 down the track by giving the elevator-rail which supports the carrier a steeper pitch than (and in the same direction as) the incline of the stationary portion or track proper, the carrier being still further accelerated by a spring, if desired-for instance, by the spring which assists in returning the track-section to its normal position.

Our invention also consists in a carrier-elevator provided with a rail or. support for the wheels of the carrier to rest on in an upright position, in combination with a single-rail pivoted track-section having a stop at or near its free end for retaining the carrier on the elevator till its supporting-rail is brought in line with the track down which it is to descend, when the said stop is depressed against the resistance of a spring out of the path of the carrier by contact with the contiguous portion of the track, the rail of the elevator on which the carrier rests during its ascent forming, when in line with the two contiguous stationary portions of the track, a substitute for and taking the place of the movable single-rail track-section when the latter is swung up and held out of line by the elevator or its carrier thereon.

Our invention furthermore consists in speoific features of construction to be hereinafter described and claimed.

To enable others skilled in the art to understand. and apply our invention, we will proceed to describe the manner in which wehave carried it out.

In the said drawings, A represents an inclined forwarding-track held in place by a bifurcated support, a, secured to a post, B, extending down from the ceiling.

b is a short movable section of the singlerail track A, one end of said sectionbeing pivoted by a pin, 0, to the upper contiguous stationary portion, d, of the track, the free end of said movable section being provided with a shaped groove, e,which snugly abuts against the corresponding tongue or projection,f, formed on the contiguous end of the other or lower stationary portion, 71, of the track. (See Figs. 6 and 7 The bottom of the stationary portion h is provided with a projection, t, which serves as a stop to limit the descent of the free end of the movable section, the bottom of the latter being cut away to fit thereon, If the free end of the movable section were raised, it would when released fall by its gravity down upon the stop 1' into its normal or closed position. lts descent is, however, accelerated by a spring, Z, one end of which is secured to the movable pivot c and its other end to the contiguous portion of the tracksupport, (see Fig. 5,) the tension of the spring being increased by the swinging up of the free end of the track-section b.

O is the carrier-elevator, consisting of two portions curved outwardly at their tops and connected by a cross-bar, a, to which the lower end of an elevating-cord, p, is attached, said cord being guided up over a pulley, q, and down within convenient access of the salesman.

r is an elevator-rail for supporting a carrier thereon in an upright position when it is to be raised and located on the track, the length of the carrier-supporting rail 1" being a little less than that of the movable track-section b,- and the inclination of the rail r is several degrees steeper than that of the contiguous stationary portion of the track. This carrier-supporting rail is pivoted at s to the top of one of the curved portions of the carrier-frame, the other or movable end of this rail being provided with a square shoulder, 15, by which this end may be supported on a similar square shoulder, 16, formed at the bottom of the contiguous side of an upright block, it, which is secured to the outer end of a latch or arm, D, pivoted at 17 to the top of the other curved portion of the carrier-frame. This upright block if is held in its normal position, Figs. 1, 2, and 4, so as to project above the top of the movable end of the rail 1", by the upward pressure of a spring, a, against the under side of the pivoted arm D, this block t, when thus projecting above the free end of the rail, serving as a stop or rest for the near wheel 18 of the carrier, whereby it is retained upon the inclined rail in an upright position, ready to be raised by the elevator and located on the traclz, Fig. 2. As the elevator is raised the carrier-wheel contiguous to the pivoted end of the track-section comes against the under side of said section and tilts or swings it up on its pivot c, and as the elevator continues to rise the stop or block t is brought in contact with the under side of the contiguous statlonary portion of the track, and is gradually depressed even with the line of the top of the carrier-rail 1", the spring-actuated arm D being tilted down thereby, and the carrierwheel being unsupported, the gravity of the carrier causes it to descend the incline of the carrier-rail, its speed being increased by the pressure of the weighted track-section as it returns to its closed position, the speed of the (8.111 811 being still further accelerated by the uncolllng of the spring Z, connected with the pivot c of said section.

Instead of the spring-actuated block t, another form of spring stop or rest for the carr1er-wheel may be employed-for instance, like that shown in Figs. 8 and 9, in which a spring-actuated bent lever, H, is pivoted directly to the front of the carrier-supporting rail, and has a projection, 12 c, at its free or unpivoted end, which comes into contact with the under side of the contiguous stationary portion of the track and is depressed thereby, so as to carry the wheel stop or rest w flush with the line of the carriersupporting rail, thus leaving the wheel of the carrier unsupported and the carrier free to descend the track.

We have herein alluded to the pivoted rail section, in combination with a carrierelevator having a carrier thereonfor swinging up or opening the pivoted section, for the purpose set forth.

3. A carrier-elevator having a rail for supporting a carrier, in combination with a singlerail track, and a single-rail track-section pivoted thereto, for the purpose specified.

4. A single-rail track and a pivoted singlerail track section closed automatically, in combination with and swung up or openedby a carrier located on a carrier-elevator, for the purpose described.

5. A single-rail track and a pivoted single-' rail track-section closed by gravity, or by gravity accelerated by a spring, and swung up or opened by a carrier located on a carrierelevator, substantially as set forth.

6. A carrier-elevator having a rail for sup-.

porting a carrier, and a stop for keeping the carrier thereon until the carrier-supporting rail of the elevator comes in line with and registers with the contiguous stationary portion of a single-rail track, in combination with an automatically-closed single-rail track-section, for the purpose stated.

7. A carrier-elevator having a rail for sup porting a carrier thereon, and a spring-actuated stop for keeping it upon said rail while being raised into line with a single-rail track, in combination with a single-rail track-section swung up by the elevator or carrier-and closed by gravity, .or bygravity assisted by a spring, substantiallyas shown and described.

8. A carrier-elevator having a carrier-supporting rail inclined downward at a greater angle than that of the single-rail track with which it connects or intersects, as set forth.

9. A pivoted single-rail track-section, in combination with a stationary single rail track provided with a stop for limiting the descent of the pivoted section, the free end of x which is grooved to fit a tongue or projection on the contiguous end of the stationary track, or vice versa, as described. 1

Witness our hands this 12th day of November, 1885.
