9 Claims. 1

My present invention involves the. construction of a building having a plurality of floors, a central elevator hatchway and a specially constructed elevator mechanism therein serving each floor and the several spaces or stalls on each of them which are arranged to receive one or more motor vehicles as they are successively brought into delivery position by the elevator.

In the accomplishment of the above purposes my invention also has for its object to provide an elevator mechanism comprising guide ways, which may be of any required length according to the height of the building served, suspended from a traveling crane, in which the elevator car is moved vertically, together with means for steadying the suspended framework whereby as it is moved laterally in the hatchway the possibility of its swaying is prevented.

A further object of my invention is to provide an improved elevator system for rapidly servicing rows of stalls on different floors of a building opening into a hatchway in which the elevator car is guided in a suspended framework by employing in conjunction therewith cable connections attached to the building and carried over sheaves attached to the framework at its upper and lower ends whereby they move in unison said arrangement permitting the framework to be made as a comparatively light structure capable of rapid manipulation laterally at the same time the elevator car is traveling either upwardly or downwardly.

To these and other ends my invention comprises further improvements and advantages as will be further described in the accompanying specification, the novel features thereof being set forth in the appended claims.

My invention contemplates the construction of a building to provide storage space for a large number of motor vehicles and associated elevator apparatus for handling vehicles with the utmost speed both in placing them in storage and subsequently delivering them on call to their owners. The building is specially constructed and comprises successive floors which preferably extend in opposite directions from a hatchway which latter is of a length coincident with the full length of said floors and of a width to accommodate an elevator car capable of transporting automobiles. The top of the hatchway extends above the roof of the building sufliciently to accommodate the hoisting mechanism and enable the elevator car to service the uppe floor of the building. Therein is housed a crane from which is suspended the guide framework for the elevator car. The hoisting mechanism for the latter and the driving devices for moving the elevator lengthwise of the hatchway and the several control devices, these instrumentalities are all carried on the crane platform.

In furtherance of the general assembly briefly set forth and to the end that the invention may be readily understood I have illustrated in the drawings the essential portions of a building which will comprise enclosing walls, two of which is shown in Fig. 2 and indicated as Ill and I0, supporting any desired number of floors. These are indicated by H, one of which ll'a represents the ground, or street, or approach level, while the uppermost floor may be roofed over as indicated by 12.

The elevator hatchway (Fig. 1) may extend across one end of the several floors but it is pref erable to locate it centrally, or thereabouts, of the building to facilitate ready access to each half portion. Some of the building floors may be located subsurface as in the basement of the building but however they are disposed the hatch way is bottomed in a pit l3. Its upper end extends above the roof l2 and is enclosed, as indicated at H. Incorporated in the building structure at the upper sides of the hatchway and at approximateLv the roof level are parallel guide rails |5-|6 along which the elevator mechanism as a whole travels.

The elevator mechanism embodies a crane portion and a suspended guide frame for the elevator car, the former carrying the drive mechanism for manipulating the crane from one end of the hatchway to the other, the elevator car hoisting devices and the several controls employed for these separate elements.

The crane, shown in plan view in Fig. 3, comprises a rectangular frame carrying a platform. It has side pieces 20-2l and connecting end pieces 22-23. Beneath the corners of the frame are supporting wheels Journaled in suitable brackets, one pair of which 24-25 are idlers, the other pair 26-21 being drive wheels, all of which are grooved peripherally to provide flanges which embrace the sides of the rails |5| 6. The supporting axles Ma-21a of the drive wheels also carry sprockets 26b- 21b which are driven by chains 26c--21c, trained over other sprockets 26d2'ld on a drive shaft 28 which extends lengthwise of the crane frame. The latter also carries a reversible motor 29 having a driving connection, such as a chain 30, extending from a sprocket on its armature shaft to a second sprocket on the shaft 28, by means of which the crane may be operated at will, in either direction from one end of the hatchway to the other by suitable control devices.

The elevator car, or cake, indicated by 40 in Figs. 1 and 2, is guided for vertical movement in a frame suspended from the side pieces Ml-2|, Fig. 3, of the crane, comprising spaced vertical members extending the full height of the building, their lower ends reaching nearly to the bottom of the hatchway pit l3. One side of this frame is constructed of a plate 4|, Fig. 4, the inner face of which extends parallel to and in alinement with the inner edge of the side piece 2|, Fig. 3, of the crane. It is stiffened along its vertical edges by angle pieces 42, Fig. 4, one edge or flange of each which lies against the inner face of the plate and the other embraces its lateral edge. Also secured to the outer face of the plate, throughout its length, is a channel piece 43. This is preferably mounted along the longitudinal center line of the plate, serving both to stiffen the plate and form a backing for the elevator car guide or way 44.

The opposite side of the suspended frame is built in the form of an open work cage forming a channel for the elevator car counterweight. It comprises the spaced guideways 45, 48 and an inner lattice work side formed of spaced horizontal members 41 and diagonal truss pieces 48 alternating therewith, also outer horizontal members 49, the ends of which are united to the corresponding ends of the similar members 41, by tie pieces. The latter also serve as stiffening backers for the counterweight guide ways 4546. A second guide way for the car, indicated by 50, is provided on the inner side of the lattice work in alinement with the corresponding guide way 44 on the vertical plate 4|.

The lower ends of the above described vertical side pieces of the elevator car frame are connected rigidly 'by cross bracing 5|, the lower edges of which lie slightly above the flooring of the pit l3 and in the space thus provided there is secured a rail 52 which extends lengthwise of the pit. This rail is in the form of an inverted T, and, against opposite sides of the upstanding portions thereof are four horizontal guide wheels 53, journaled on studs carried on the cross bracing members 5| (Fig. 6). a

An additional feature of my invention is the frame stabilizer which is of especial importance because it enables the elevator car guide frame to be made as a comparatively light structure yet operated with precision, without distortion in conveying loads and capable of being operated under high speeds. .In the accomplishment of this object I provide at the upper end of the car guide frame, at one side thereof, a double groove sheave 60 journaled on a bracket 6| directly below the crane (Figs. 2 and 8). At the extreme lower end of the frame and on the same side I also mount a similar sheave 62. Both of these sheaves are journaled to rotate in a plane in the direction of travel of the car frame and carry cables attached to the walls of the building at the two ends of the elevator hatchway. The arrangement of the stabilizer is illustrated diagrammatically particularly in Fig. 8. One of the cables designated 63 is attached to one of the walls ID of the building at the top of the hatchway and extends over the sheave 60 thence downwardly around sheave 62 as indicated by a and horizontally, as shown by 63a, to the foundation 65 beneath the building wall In. A second opposing cable 66, attached to the wall i0, is also trained over the top of sheave 60, and extends downwardly, as indicated by b, thence around sheave 62 and horizontally, as shown at 66a to the point of anchorage on the foundation 6! beneath wall I0. Provision is made for maintaining each of said cables under tension as by means of turn buckles 68.

From inspection of Fig. 8 it will be seen that when the crane moves the elevator car guide frame in one direction the upper course of one of the cables, say cable 63, will be lengthened and by reason of its cross connection a, its lower end 63a will be shortened. Simultaneously as the upper course of cable 66 is shortened its lower course 66a, being acted upon by the intermediate portion b, will :be lengthened. Accordingly the movement of the crane and car guide frame in the opposite direction produces a reversal in the disposition of the cable sections as just described. It will be seen therefore that by reason of the cross reeving of the cables in the opposite directions around the sheaves at the two ends of the guide frame, perfect synchronism in the movement of the upper and lower ends of the frame is maintained at all times. Since the guide frame is thus held in a truly vertical position at all times it is possible to shift it through the action of the crane drive motor 29 at maximum speed.

At a mid point, or otherwise as may be desired and depending on the height of the building, and in alinement with one of the floor levels, the car guide frame carries a horizontal bracing unit the ends of which engage tracks in the exposed edges of the flooring to resist thrust that may be imparted to the framework by the shifting of the center of loads on the car platform, such as the sudden starting and stopping of a motor vehicle as it is driven onto and off from the elevator car. This bracing is in the form of a truss which at one side comprises alined bars 10 extending horizontally from the opposite edges of the frame plate 4| and angularly disposed bars II fixed at their proximate ends to the stiflening ribs 43 and united at their extremities to the ends of the bars 10. At the opposite side of the suspended guide frame similar alined bars 12 extend laterally from the two inner edges of the lattice work while other bars 13 project from the outer corners of said lattice work to the outer extremities of bars I! (see Fig. 4). In the mounting of this trussing frame it is located at the level of one of the intermediate :building floors and the united ends of the several bars are connected by tie rods 14-45 which also serve as spacers. At each of the four corners of the trussing .frame I locate a wheel or roller 16 positioned to bear against rails ll-18 embeddedin the free edges of the floor at opposite sides of the hatchway.

The elevator car 40 comprises the usual loading platform suspended from a cross head which, as

shown in Fig. 4, comprises spaced channels IHI.

The latter may serve as the point of connection for the hoisting cables or as supports for hoisting sheaves. The cross head is centrally located and is in alinement with the rails 44 and on which the elevator car is guided by the usual guide shoes 82.

The elevator car counterweight, indicated by II in Fig. 1, is guided in the lattice work cage on the rails 45-46 (Fig. 4) and is connected to the car by counterbalancing cables which pass over the sheave 84 located in said lattice work below the crane.

The elevator car hoisting machinery is carried on the crane platform and indicative thereof there is shown in Figs. 1, 2 and 3 a reversible motor 85, the armature of which is in driving connection with a worm gear unit 86 for rotating a traction sheave 81. The arrangement of those parts as shown is designed for a two-to-one hitch, the outer edge of the sheave 81 being alined with one edge of the adjacent counterweight sheave 84 whereby the multiple hoisting cables which are anchored at their ends to the crane pass downward and beneath the two sheaves 88-89 (Fig. 4) on the car cross head ll-fl thence upward over the traction sheave O1 and counterweight sheave. Control panels ll-'9l for the floor selector and tier selector, re spectively, and the governor safety device 92 are also carried on the crane.

Electric current for energizing the motors 28 and 85 is supplied by trolley wires 93-94-45, extending lengthwise across the top of the hatchway,..at one side thereof, with which engage suitable trolleys on a frame 96 located at one end of the crane platform.

The arrangement of the operating mechanism is such that it can be manipulated by the standard push button controls and I have therefore not illustrated these but it will be understood that on the elevator car there will be a series of circuit operating button switches, one for each tier of parking stalls for operating the crane hori-. zontally along the hatchway, in opposite directions and one for each floor level of the building, whereby the elevator car will be simultaneously moved vertically either upward or downward.
