Application filed March 11, 1929. Serial No. 346,209.

l ple, smooth action which will not be likely to dislodge dishes or other articles carried on the trays.

A-further object is to provide an elevator, which will conduct the loaded trays efficient- -0 ly and safety from one elevation to another.

The principal features of the invention consist in the novel construction of a guide for the elevator chains and the tray carrying members whereby the trays are conducted between smooth vertical walls and are transferred to a horizontal conveyer without interrupting the movement of the vertical conveyer and maintaining the tray in a level position throughout its movement.

In the accompanying drawings, Figure 1 is an elevational View of our improved elevator and transverse transfer member.

In carrying this invention into effect a pair of vertical casings 1 and 2 are i lled in a structure spaced apart by the horizontal spacing rods 3.

The casings 1 and 2 are preferably formed of metal plates 4 bent into U-shape. These are arranged vertically and spaced apart and between the flanged sides thereof are arranged the flat vertical plates 5, said plates 5 being spaced from the flanges of the U plates to form the vertical slots 6.

Flanged channel-shaped plates 7 are secured on the inner sides of theflanges of the plates 4 and 5 to support said plates rigidly to maintain the vertical slots 6.

Horizontally arranged shafts 8 and 9 are arranged respectively at the top and bottom of each of the vertical casings 1 and 2. These shafts carry sprocket wheels 10 arranged to align with the vertical slots 6 and endless chain belts 11 are mounted on the sprockets to travel in the channels formed by the plates 7.

At spaced intervals in the length of the chain belts 11 there are arranged links 12 which have squared lugs 13 which project through the vertical slots and are provided withthreaded holes 14 into which bolts 15 are threaded.

The lug-carrying links 12 are arranged in common horizontal planes and angle bars 16 are secured by the bolts 15 to each of the adj acent pairs of lugs 13, said angle bars being thus arranged in horizontal pairs with the horizontal flanges thereof forming tables to receive the side edges of the trays that are to be carried.

The chain belts 11 are driven by a motor 17 through a suitable arrangement of gears 17' The space between the. vertical casings 1 I and 2 is open at two sides but may be of course closed for the entire length of the carrier if desired,1oropenings may be left therefrom the in for access tothe interior where the trays are movin In the iagramgeillustr'ation of Fi re 1 there is an opening atithe to end of t e vertical casing givin access to t e space between thernto permit t e withdrawal of the trays elevator formed by the travelling belts.

It is desirable that trays or packages arriving at the top of the elevator be automatically removed and either deposited or carried the frame in the same horizontal plane as the shafts 19 and carry the sprockets 21. v

A pair'of chain belts 22 are arranged upon theforward setof sprockets 20 and a pair of chainbelts'23 are arran ed upon the other set of sprockets 21 and t e sets of sprockets are connected to operate in unison.

A pair of long fiat arms 24 are pivotally supported about mid-way of their length on pin extensions 25 from the chain belts 22 and the ends 26 of said arms are pivotally supported on the pin extensions 27 from the chain belt 23.

The pin extensions 25 and 27 are so arranged in relation to the sprockets 20 and 21 that they travel always a uniform distance apart and carry the arms 24 horizontally and when the arms move towardthe elevator they progress at the underside of the sprockets and extend into the elevator between the vertical casings 1 and 2 and as the pins carrying the arms swing around the end sprockets the arms lift upwardly underneath the trays and lift the trays from the vertical carrier and the progressive movement of the chain belts 22 and 23 carries the trays clear of the elevator structure.

The sprockets 20 and 21 are driven by a centrally arranged chain belt 28 carried in the frame 18 and engaging sprockets mounted on the, shafts 19.

The belt 28 is carried along the frame 18 any desirable distance and its upper reach slides upon a horizontal support 29 forming part of the frame 18.

This chain is guided by the upwardly projecting edges 30 of the plates 31 which form thecentral part of the frame structure.

The chain belt 28 is provided with lug extensions 32 which are adapted to engage the trays and push them horizontally along the frame.

. Horizontal skids 33 are arranged at either side of the frame to support the trays and longitudinal side guides 34 are carried by the side bars 35 of the frame. These guides endesirable to use lateral. carriers at different" floors. Such an arrangement is illustrated in the diagrammatic view shown in Figure 5, where lateral horizontal carriers are arranged at both sides of the elevators and in such a manner that trays may be lifted from the elevators to be conducted in either direction horizontally therefrom at any floor. Y

The lateral carriers arranged at opposite sides of the elevator may travel in opposite directions but each is provided with a pair of lifting arms 24 adapted to extend in underneath a tray carried by the elevator. I

- In operating a system in which a plurality of lateral conveyers are arranged in conjunction with a vertical conveyer such as shown in Figure 5, it will of course be necessary to arrange some form of control which will regulate the lateral elevators to' operate at the proper period in harmony with the vertical earner.

In Figures 6 and 7 I have shown a tray 36- provided with a plurality of switch operating elements in the form of hinged arms 37 These arms when swung to the outward side of the tray each present an obstruction member which will in the course of travel of the elevator engage the projecting shoe 38 of a switch member 39.

The switch members are electrically connected with suitable electrically operated mechanisms for throwing the lateral conveyer into operation in unison with the vertical conveyer so that the lifting arms will remove the tray therefrom. If desired, the switch member may be made to operate a signal and if the tray is not removed from the elevator a second switch may be arranged to stop the elevator.

In a system such as illustrated in Figure 5, the trays will he provided wit-h a number of signal operating arms 37 corresponding with the number of lateral carriers and the operator in placing the trays will set the proper arm so that it will operate the proper switch at a time set with the operation of the elevator so that the horizontal arms 24 of the lateral carrier will operate as the tray is carried past the horizontal carrier, said arms operating to lift the tray clear of the'vertical carrier and deposit it on the horizontal member.

It must be understood that the arrangement herein shown is only diagrammatic and that any suitable form of switch operating mechanism may be arranged so that any one of the lateral conveyers may be operated ata desired period to lift trays from the elevator or so that the elevator may be arrested at any desired point to permit the removal of trays by hand.

Further, the illustration and description an elevator and in conjunction with it a means 'for transferring trays carried thereon to a horizontal carrier. It must be understood, however, that the invention may be applied to utilizing a horizontal carrier in connection with a lowering device, wherein the horizontal member will pick the trays from the horizontal carrier belt and carry them in between vertical members similar to 1 and 2 and deposit them upon. the bars 16 of bolts operating in a downward direction.

A device such as described is flexible in its application, it may be installed as a simple elevator to carry trays up or down. It may be provided with switch contacts to give signals when trays are approaching certain predetermined points and to operate stop switches, and it may be arranged in operating harmony with one or more horizontal car-' riers, all of which are contemplated in the use of the invention.
