This invention relates to automobile storage and it has for its principal object to provide nuan elevator system involving the use of a pluralit of cages moving in two columns and shi table from one column Yto another, wherebyra large number of motor vehiclesI may be stored in a structure covering a comparatively small 'ground-area while all the vehicles are readily accessible for individual removal.

Other objects relating'to details of construction and to novel arrangements and combinations of parts will be fully brought out in` the course 'of the following description with reference to drawings.

In the drawings in which similar characters of reference designate corresponding' parts'throughout the several views Figure 1 represents a fragmentary sectional -plan view of the structure involving the elevator-apparatus in accordance with my invention,

Figure 8 an enlarged sectional view of a dog and its controlllng means, included in the construction of the lifting means of the the accompanying Figure 11, a view of a portion of one of the cables included in the shifting element of the apparatus.

All of the views are more or less diagrammatic, it being understood that the novelty of the invention resides primarily in the arrangement and method of loading, elevating,. shifting and supporting the vehicle 'carrying Areceptacles or cagesfand that the.`

lmechanisms by which these results are accomplished are subject .to variation within the scope and spirit of the invention as here- -inafter to be set forth and as delinedin the hereunto appended claims.

Referring further to the drawings the reference numeral 5 designates a shaft or well in a' building in which the system of elevators and its operating mechanism are assembled. The shaft has at opposite sides thereof a landing Hoor 6 on which the vehicles are moved to and from the load-'receptacles o r elevator cages 7 and the operating mechanism is preferably installed in a chamber 8 at the bottom of the shaft, separated from the main portion of the same, by a horizontal partition 9.

The elevator cages are rectangular in form,

open-ended and o sufficient size to house any motor vehicle -of standard proportions..

Each cage has at its top, a series of rollers 10 for Athe movable support' of a superposed cage and vit has at opposite ends of its floor, outwardly projecting pins 12 which 1n the operation of the apparatus-,cooperate wlth lugs on shifting cables hereinafter to be described. i

The cages are y vertical guide ways which d1v1de the shaft vinto two adjoining sections 13 and 14 and each upper cage may be supported jon the rollers of the next lower one as clearly shown in the drawings.

The operating mechanism bywhich the. columns of cages are lifted and by` which they are shifted from one shaft-section to another, may, as stated hereinbefore, be of any suitable character, that .shown in the drawings consisting principally of two hydraulic rams upon which the columns are supported. Each ram has av plunger 16 mounted in two columns in inder 15 and the plunger supports a skeleton head 17 which in operation engages the lower cage of the column in the respective sectiony of the shaft.

The two cylindersof the rams connect with a pump-unit 18 by which a fluid body is transferred from one cylinder to another alternately, so that one plunger is lifted while the other one is lowered by its load in alternate movements controlled by the operation of the pump. t

Extending transversely of the shaft-sections in the lower portions thereof are two airs of horizontal beams 19, carrying antiriction rollers 20 and constituting platforms for the support of the lowermost cage of the column. At the up er ends of the upright members of the ske eton heads of the ram plungers, are pivoted dogs 21 which may be moved into and out of t 1e paths of the elevator cages by crank-movements 22 in connection with pistons fitted for reciprocation in cylinders 23 which by means of pipes .24 are connected at opposite sides of their plstons, with an' air-reservoir 25 in the chamb er 8.

Pivoted on the upright guide-members of the shaft-sections at a level slightly above the top of the cages supported on the platforms provided by the Cross-beams 19, are dogs .26r which likewise may be thrown into or out of the paths of the columns of elevator-cages, by crank movements 27 connected with pistons in air-cylinders 28 which at their opposite ends are by means of pipes 29 connected with the reservoir 25.

In Figure 2 has been shown one Set .of dogs for each shaft section which in practlce supports the-entire column of cages, but 1n Figure 7 has been depicted a modifcationof this construction Vin which the cages above the lowermost ones are individually supported on sets of dogs-26 and the dogs o the various sets are connected for simultaneous The last described system is distin ished from the first described system in t at the 'operation by means of pivoted bars 30.

weight of the cages and their loads is dis-l tributed over a number of sets of supporting members when the elevating systemis in a condition of rest, but whether the multiple sets of dogs or .the single sets of dogs are used in the shaft, these do s as well as those on the rams must be su ciently strong to sustain the weight of all the cages in each column and their loads with a reasonable margin of safety.

The pump unit 18 is controlled'by an aircyli'nder 31 similar in construction to those associated with the' dogs in the elevator shafts and on the ram-plungers, the cylinder 31 being connected with the reservoir 25 by a 'pipe 32. The flow of air throu h the pipes connected to the various cylin ers -is conoperation of the system.v

' operating mechanism as the case may be.

Neither of the mechanisms have been shown in the drawings which as stated hereinbefore, depict the operating system of the invention more or less diagrammatically and not with reference to details of construction.

The shifting element of the invention by which the cages are transferred horizontally from one column to another consists inthe construction shown, of two cables 35 mounted to run over sheaves 36 and connected at their ends to the skeleton heads 17 of the two rams. The sheaves are arranged so that portions of the cables extend horizontally in planes with the bottom parts of the upper and lower cages ofthe two columns and these portions of the cables are provided with U-shaped lugs 37 to engage with the laterally projecting pins 12 on the cages asl best shown in Figure 11 of'the'drawings.

Premising that the cages are in the position illustrated in Figures 6 and 7, it will be noted that in one of the columns, that at the right hand side of Figure 6, the lowermosty cage rests u on the cross-beams 19, below the landing oor while the next following cage is supported on a level with the floor upon the inwardly projecting dogs 26 on the upright'guide ways of the respective shaft-section. The other cages of the column may be supported upon each other and together upon the cage which rests on the dogs on a level with the landing floor, in case but one set of dogs is provided for the purpose as shown in Figures 1 and 2, or they may be supported individually on the Ainwardly projecting dogs when a system of interconnected dogs is employed to that 'end as has been shown in Figures 7 and 9.

The plunger of the ram below the column is in its retracted position and the uppermost cage of the column is below the top of the shaft at a distance therefrom substantially equal to the height of one of the cages, to provide a's ace 38 into which the said cage of the co umn may be shifted in the In the other column of cages, that at the left-hand side of Figure 6, the lower-most cage is on a 'level with the landing Hoor,

supported on the dogs projecting inwardly from the respective shaft-section and the other cagesare sustained either upon the lower cage or upon the series of dogs pro- -is in its extended position in which the head jecting into the shaft as hereinbefore explained with reference to the first described column. The plunger of the respective ram thereof is contiguous to the bottom of the 'lowermost cage, the space 39 between the The two cages which are on a level with the landing floor are in a position t be loaded with automobiles driven into their open` ends from either=direction and when one or both of the cages are loaded, the operating l mechanism is actuated through the medium of the switch 34 to bring other empty cages in register with the lloor. The operation by hich this result is accomplished is as follows: The dogs 26 in the shaft-sections are moved about' their pivots to their retracted positions and the dogs 21 on the heads of the ram plungers are simultaneously moved to their inwardly projecting positions.V The two columns are now supported on their respective rams and whensubsequently the position of the two ram plungers is reversed by actuation of the v pump unit through the medium of the valve 33, the column at the right hand side of Figure 6 i's lifted to the position illustrated m 4Figure 2, in which its uppermost cage occupies the space 38 and its lowermost cage is brought to a level with the landing iloor, and the column at the left hand side of Figure 6 isv lowered until the lowermost cage rests on the rollers of the cross beams 19 and the upper cage is distand from the top of the shaft to provide the' space 38 into which the upper cage of the other column may be shifted, all as illustrated in Figure 2. Y

When the two columnshave thus reversed their positions, the shaft-dogs are again moved to their projecting positions whereby to support the columns independent of the rams, and the dogs on the rams are at the same time retracted, which leaves the rams free for a separate operation by which the uppermost cage of one of the' columns and the lowermost cage of the other column are shifted horizontally into the open spaces 38 and 39.

During the upward and downward movement of the columns the pins 12 on the upper and lower cages were separated from the U-shaped lugs 37 on the cables immediately.

after the cages were moved from their posltions of rest, thereby permitting the cables to move with the rams without interference with the movement of the cages In order that Vthis separation of the pins from the lugsV may occur immediately after the columns have their movement, the lugs have been made suiciently wide to permit of a free movement of the cable during the time he pins on the cages are separated, from the ugs.

In the next step of the operation, the ram lplungers, are reciprocated independently of the columns for the purpose of shifting the upper cage of the ri ht hand column into the space at the top o the left hand column' while at the same time the lowermost cage of the left hand column is moved into the Y space below the right hand column, all of Y which is accomplished by the longitudinal movement of the cables instigated by the' reciprocating motion of the ram-plungers and the engagement of the lugs on the cables with the pins of the respective cages.

At the termination of this ymovement of the rams and the cages, the ram-plungers are returned to their original positions, as shown in Figure 6.

A The operation as hereinabove described is repeated each time one or both of the cars on the level with the landing floor are loaded or whenever it is desired to withdraw a car in one of the loaded cages of either column, by bringing the cage to the level of the iloor.

It will be apparent that by the use of my improved storage-system a large number of automobiles may be stored in a shaft the ground area of which is but slightly larger than the space ordinarily occupied by two of. the vehicles placed side by side, that the automobiles are readily moved into the storage shaft and as easily removed from the same and that each of the cars is automatically protected againstl unauthorized re` movalas long as the cage into which it is stored is raised above the level ofthe landing iloor.A

The open-ended cage permits of cars en- A v obtained in other ways or that the cages may Y be supported directly one upon another without the intermediary of antl-friction appliances.

One of the distinctive features of the in-A v vention resides in supporting the columns of.

cages and their loads from below the columns, and in utilizing'the supporting mechanism to lift the columns alternately as described. This feature of the invention relieves the building or other structure in which the shaft is formed, from most of the strains resulting from .the weight and movement of the loaded cages, in the operation of vthe apparatus.

While the cages have been shown and described as being open at both ends, it is to be understood that they may -be open at one end only or provided with doorsif necessary. It is also to be understood that the operation of the elevating and shifting mechanisms may be reversed at will, which increases the accessibility of the cages for the removal of the vehicles stored therein.
