JOHN HALL, OF GRESTON, IOWA.

ICE-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 392,203, dated November 6, 1888.

' Application filed December 17, 1887. Serial No. 258,204. (No model.)

To all whom it may concern.-

Be it known that I, J OHN HALL, a citizen of the United States, residing at Creston, in the county of Union and State of Iowa, have invented certain new and useful Improvements in Ice-Elevators; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in ice-elevators; and it consists in the novel arrangement and combination of the various parts, as will be hereinafter fully set forth and claimed.

The object of my invention is to provide a device of the class above named whereby blocks of ice can be elevated and the devices employed for elevating the same be operated in an easy and'simple manner, as will be understood by reference to the accompanying drawings, in which- Figure 1 is a side elevation of the device in operation. Fig. 2 is a front elevation of the same. Figs. 3 and 4 are detail views of the engaging-hook, and Figs. 5 and 6 are views of the hooks provided with the rollersupports and operating-levers.

Referring by letter to the said drawings, A designates an elevator-frame provided with an inclined chute, 13, having its upper end firmly secured to the uprights of the frame, while the lower end is adapted to rest upon a suitable support near the ice to be elevated. Intermediate of the top'and bottom of this inclined chute are secured on the rear side thereof a series of shelves or platforms, 0, for the purpose of holding cakes of ice after they have been elevated.

D is a roof or cupola, which covers the rear uprights and forms a housing or shelter for the operating machinery. This machinery consists of the sprocket-wheels b b, preferably two in number, which are mounted upon a shaft, E. This shaft is journaled in boxes made fast to the cross-bars a a, that are arranged just below the roof or cupola D. I also provide a floor, E, beneath the operating devices for the accommodation of the operator. This floor is made accessible to the inclined platform 13 by means of a small staircase or ladder.

F F designate short standards that are at tached to the lower end of the chute B.

The sprocket-wheels c c are mounted on a shaft, H, the ends of the latter being j ournaled in suitable boxes, the said wheels being of a similar pattern to those arranged at the top of the chute B.

I is an endless sproket-chain, which connects the wheels I) b and c c and rotates the same, the motive power being furnished by agear-pinion mounted on one end of a shaft, J, that is journaled in boxes fixed to the crossbars a a just forward of the shaft E. At the other end of the said shaft J is mounted a band pulley, K, that is connected to any suitable driving mechanism bya belt or by gear-wheels engaging with the pinion L, mounted upon the shaft J intermediate of its ends.

My carrying device proper consists of the ice-engaging hook d, formed at one end with two diverging arms, 6 e, to insure strength to the said hook, while at the other end it is provided with an attaching eye, f. The said hook is connected through the medium of this eye and a rope of suitable length to the hook g. This hook g is made of two parallel strips of metal, preferably highly-tempered steel,and which are curved downwardly at their forward ends to form a hook portion for engagement with a bar .of the sprocket-chain.

N represents a releasing dog or lever the lower end of which is pivoted between the jaws of hook g, as shown, and serves to release said hook from the sproket-chain whenever the upper end of said dog is brought against a transverse wire, 0, which extends from side to side of the main frame above the sprocketchain. As the chain is drawn upward, the lever portion of the dog is forced downward and lifts the hooks at its sides from the bar to which they are attached.

Y indicates a pulley arranged in a bracket, 2, and to the side of the main hook g.

G represents a wire or rope extending from the cupola of the frame to a post at the bottom of the chute.

After the ice has been elevated to the proper shelf or platform and the hook 9 released from the sprocket-chain the operator at the top of the chute takes the hook g, with its attachments, and suspends it upon the wire G by v placing the pulley Y on said wire.

The hook 5 will then descend on said wire to the bottom 01' the chute, where it is taken by another operator, and. after connecting it with the sprocketchain and a suitable load of ice the work of elevating is repeated.

By the construction illustrated it will be seen that the ice is not carried upon the endless belt or chain, but that the chain travels above the ice. This is particularly desirable in the present construction, as the chain is thereby adapted to cooperate with the tripping and gripping devices and the ice allowed to be discharged on any of the lateral chutes.

Having described my in\"e11tion,what I claim 1. A11 ice-elevator comprising an inclined frame, transverse wire, as described, an end less chain traveling at a distance above the ice-track, the ice-hooks, the hooks having releasing-dogs, and the rope connecting the said hooks with the ice-hook, substantially as specified.

2. In an iccelevator with an inclined frame and a return-wire, as described, the combination, with an endless chain and cross-wire, O, of an ice-hook and a hook adapted to engage the endless chain, provided with a pivoted releasing dcviee, and a rope for connecting said hooks, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
