ALFRED XV. CASSADY, OF LAMAR, MISSOURI.

ELEVATOR.l

SPECIFICATION forming part of Letters Patent No. 592,982, dated November 2, 1897.

Application filed April 5, 1897. Serial No. 630,893` (No model.)

To @ZZ whom it may concern.-

Beit known that I, ALFRED W. Cassani?, a citizen of the United States, residing at Lamar, in the county of Barton and State of Missouri, have invented a new and useful Elevator, of which the following is a specilication.

This invention relates to certain improvements in that class of elevators which are adapted for raising and lowering goods and freight, and has for its object to provide a device of this character of a simple and inexpensive nature which shall be especially adapted for use in stores and-warehouses for raising and lowering goods and for moving the same about-from one part of the building to another.

To the accomplishment of these ends my invention consists in the combination, with track-rails arranged in a vertical plane contiguous to a wall or shelving of a store or warehouse, of a single column or Vupright disposed laterally adjacent to said wall or shelving and equipped at its upper and lower ends with carrying and guide rollers adapted to said tracks and arranged to `sustain the post or column in a proper vertical position, a vertically-adjustable platform mounted in a novel way to slide on said single column and arranged to project outwardly from the front and the two sides 'of such column, thus leaving the rear of the column practically free from obstructions, so that the apparatus may be erected closely adjacent to a wall or shelving without having the latter interfere with the movement of the column and platform along the wall or shelving, and a novel mechanism whereby the platform is balanced and provision is made for adjusting the platform vertically on the column, as may be required.

The invention also contemplates certain novel features of the construction, combination, and arrangement of the various parts of the improved elevator; whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

ln order that my invention may be the better understood, Ihave shown in the accompanying drawings an elevating device embodying my improvements, in which drawings- Figure 1 is a perspective view showing an elevator constructed in accordance with my invention. Fig. 2 is a sectional view taken vertically through the upright of the elevator and showing the means for raising and lowering the shelf. Fig. 3 is a fragmentary sectional view taken in a plane at right angles to the plane of the section in Fig. 2 and showing the elevator-upright in front elevation.

ln the views, 1 indicates the wall of a room or building wherein my improved elevating device is arranged, this wall being, as shown, provided with shelves 2 2 to receive goods for storing. The elevating device constructed in accordance with my invention is adapted for movementalong the wall l, so that its shelf may be employed for raising and lowering goods to or from the upper shelves 2 at any part of the room or building desired.

3 indicates the ceiling of the room, from which is suspended, adjacent` to the shelves 2, a stout beam 4, parallel with the iioor of the room', being suspended upon suspensionrods 5 5, as shown in Figs. 1 and 2. On the beam 4t is arranged a track G, extending lengthwise of said beam, along which track are adapted to run track rollers or wheels 7 7, carried at the upper ends of hangers S, connected at the opposite ends of a horizontal beam 9, extending under the beam 4 and serving to support the upright ll' of the elevating device, which is connected at its npper end thereto by means of stout anglebraces 10, as clearly shown in Fig. 1.

The lower end of the upright 11 is formed into a foot 12 of less thickness than the body portion of the upright, said foot being centrally recessed and provided with braces 13, extending across itsfront and rear sides, between which braces is held to turn a roller la, adapted to engage a track l5, secured to the door parallel with and immediately under the track 6 on the beam a.

16 indicates a platform mounted for movement vertically on the upright 11, this platform being connected with a frame comprising vertical side bars 17, extending above the IOO platform 16 and adapted to stand at opposite sides of the upright 11, as clearly shown in Figs. 1 and 3, the side bars being connected at their lower ends by a cross-piece 17, ex-

' tending between them on the rear side of the upright 11 and being connected at their upper ends by similar cross-pieces 1818, extending across the front and-rear sides of the upright and serving to support shelves 19, upon which may be arranged the goods or freight to be raised or lowered.

In order to permit the frame whereon the platform 16 and shelves 19 are carried to be moved freely up and down along the upright l1, I provide rollers 20, extending across the front and rear faces of the upright 11 at the lower and upper parts of the frame, respectively, and to relieve the friction between the side bars 17 of the frame and thesides of said upright 11 I provide said side bars, as seen in Fig. 3, with roller-bearings 21 at their upper and lower parts.

To support the frame whereon the platform 16 and shelves 19 are carried when in a lowered position, I provide the foot 12 of the upright 1 1 with lateral projections 22 at opposite sides, which projections are provided with elastic cushions 23, arranged in position to engage the under side of the frame whereon the platform is carried and support the same above the iioor of the room wherein the elevating device is located.

To hold the frame which carries the platform 16 and shelves 19 in its lowered position, I employ a detent 24, pivotally mounted on the platform 16 in position to be conveniently operated by the foot of a person standing upon said platform, said detent having its engaging end 25 adapted for engagement with a recess 26, formed in the front face of the upright 11 at the lower part thereof, and said detent is provided with a spring for holding it with its end 25 normally engaged with said recess 26.

To permit of conveniently raising and lowering the frame carrying the platform 16 and shelves 19, I provide at each side of the platform 16 a cable or other iexible connection 27, connected at its lower end to the platform and extending up alongside the side pieces 17 to the upper part thereof. The upper ends of the cables 27 are carried through apertures in the upper ends of the side pieces 17 on the rear side of the upright 11 and are connected together, as shown at 28 in Figs. 2 and 3, and from their point of connection extends upwardly a cable or other flexible right 11 and around a sheave orvpulley 34 at the upper part of the upright 11, whence the said cable extends up and is connected with a weight 35, mounted to play vertically in a channel or way 36, formed in the body portion of the upright 11, as clearly shown in Fig. 2.

In operation the Weight 35 will be of suficient avoirdupois to counterbalance the weight of the platform-carrying frame, together with the weight of a man standing upon the platform, so that the person operating the device and standing upon the platform 16 may by pulling upon the rope or cable 31 at the front of the upright 1l conveniently raise or lower the frame without stepping off the platform 16, so that when it is desired to load or unload goods upon or off the upper shelves 2 this can be done without inconvenience, and when it is desired to load the shelves 19 of the platform-carrying frame at one part of the building and move the same along, so asto unload the goods therefrom at another part of the building, this can be donc by seizing the shelf with the handsand moving the device along the upper and lower tracks 6 and 15.

From the above description it will be seen that the improved elevator is of an exceedingly simple and inexpensive nature and permits the goods or freight to be transported from one part of the building or store to another, and also permits said goods to be conveniently raised or lowered, and it will also be evident from the above description that the invention is capable of considerable modiication without material departure from its principles and spirit, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the parts herein set forth.

Having thus described myv invention, I claiml. rlhe combination with suitable tracks, of a single, hollow column or upright adapted to travel on said tracks, a platform constructed to embrace said column on three of its sides, but leaving the rear side thereof free and unobstructed, a counterbalance mounted in said column, suitable guides near the extremities of said column, and a single continuous cable attached at its ends to the platform and the counterbalance, respectively, and passing over said guides on the column, substantially as and for the purposes described.

2. The combination of a single hollow column provided with suitable guide and carrying rollers overhead and iioor rails or tracks to which said rollers are tted, a counterpoise-weight slidably mounted in said hollow column, a platform mounted on said single column to slide freely thereon, a single continuous cable passing over guides at top and bottom of the column and having its ends attached respectively to the platform and to the counterpoise-weight, and bumpers car- IOO IIO

ried by the column and arranged to sustain the platform when lowered, substantially as specified.

3. The combination of a hollow column, a platform mounted to slide vertically thereon and having the upright bars 17 at the sides of the column', guide-sheaves j ournaled in the column above and below the limits of the travel of said platform on the column, a counterpoise-weight slidable wi thin the hollow column, and a single continuous cable branched at one end, carried through the bars 17 and attached to the platform, said table being carried over the guide-sheaves and attached to the counterpoise-weight, substantially as described, for the purposes set forth.

i. A recessed platform provided with upright side bars 17, the horizontal cross-bars 1S, 19, the shelves attached to the cross-bars 1S, and rollers 20, 21, journaled in the side bars 17, combined with a single column fitted between the bars and in the recessed platform for the rollers to ride against the several sides thereof, a counterpoise -weight, and a continuous cable attached to the platform and the counterpoise-Weight, substantially as described, for the purposes set forth.

l 5. The combination with suitable tracks, and a hollow upright or column, of a Vertically-movable platform having a guide-frame which embraces said column, a guide-roller 32 at the base of the column, other guiderollers 30, 34 near the upper end of said column, a continuous cable having branches at one end which are attached tothe guide-frame and the platform, and from thence passing around the sheaves 30, 32 and 34, and a counterbalance to which the other end of said cable is fastened, as and for the purposes described.

In testimony that l claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

ALFRED W1 CASSADY.
