GEORGE W. GOODELL, OF BEARDSTOWN, ILLINOIS.

ICE-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 231,709, dated August 31, 1880. Application filed July 8, 1880. (No model.)

To all whom it may concern Be it known that I, GEORGE W.G0ODELL, residing at Beardstown, in the county of Cass and State of Illinois, have invented Improvements in Ice Elevating and Lowering Machines, of which the following is a specification.

My invention relates to an icelowering machine, which may also be used for an ice-hoisting machine; and my invention consists in the combinations of parts hereinafter fully set forth and claimed.

in the drawings, Figure 1 is a front elevation, showing the arrangement of the cable for.

lowering ice and the brake mechanism. Fig. 2 is a vertical section, showing the form of the cage, the hoisting-cable, &c. Fig. 3 is a detail view of one end of theiceslide, showing a device for starting the ice to sliding when putting ice into the ice-house, and a modification of the device for keeping the ice from sliding off the cage outwardly.

A is the sill supporting the posts B B B between which the cage or platform 0 and the counter-balance 1) work.

E is a cable, one. end of which is secured to the post B at b, from whence it passes upward and over a pulley, F, thence down heneath the counterbalaucepulley F, thence up over the pulley F thence down beneath the cage-pulley F thence up over the pulley F, and from thence down to a windlass, G, by which it is shortened or lengthened,as may be desired.

The counterbalance D, which works between the posts B B, may consist of a solid piece of metal or other heavy substance, or of a box, in which may be placed stones or other heavy matters, so that it may be made to vary in weight as occasion may require.

(1 (Z are guide-rollers on the counter-balance running against the upright timbers or posts B B.

The cage 0 is guided on the posts B B by friction-rollers o c. Said cage has vertical side pieces, 0, cross-bar c and horizontal baseframe 0 c are braces.

H is the ice-slide frame. This is pivoted to the cage at h, so that it may be tilted to cause the ice to slide off it upon the rails h, upon which the blocks of ice are supported.

ject, and which is connected In Fig. l the device is shown as adapted for taking ice from the icehouse, and in Fig. 2 it is shown for putting ice into the ice-house.

l is a drum secured to the shaftf, to which the pulley F is also secured. The drum 1 has a rim, J, atone end, on which works a brake.

The brake consists of two levers, K K, con-.

M is a lever, pivoted at m to any fixed obat one end by a link, N, to the weighted end of the lever K, and to the other end of which is connected a cord, 0. By pulling down the cord 0 the weighted end of the lever Kis raised and the brake shoes removed from the rim of the drum I. V

P is a support to sustain the free end of the lever K when the brakes are off the drum.

R is a block (see Fig. 2) secured to the uprights Q near their bottom, the purpose of which is to tilt the ice-slide frame outward in taking ice from the ice-house and cause the ice to slide off the cage; and S S are duplicate frames, pivoted to the tilting ice-frame at such a point that the controlling-weight is at the heel of each frame, so that the toes of the frames are lifted by the weight of the heel. Upon the toes of the frames S and b" are backwardly-inclined claws s, to' retain the ice upon the rails. I

In loading the ice upon the rails it strikes against the inclined outer side of the claw and presses it downward, raising the heelof the frame; then when the ice-block has passed over, the claws are raised by the Weight of the heel end of the frame. When the cage descends to the place of unloading, the heel of the frame S comes in, contact with a projection, R, and the toe of the frame is lowered to depress the claws s and allow the ice to .slide off the rails. When the ice is being carried upward in filling the ice-house, the toe of the frame comes in contact with a projection, Q, and as the cage ascends the claws are held down to allow the escape of the ice from the rails into the house on the tilting of the railframe.

T is a yoke, of which there are preferably two, one being attached to each corner of the cage next to the ice-house, whose office it is to tilt the cage when it has ascended to the placefor unloading by coming in contact with the adjustable cross-piece U. The cross-piece U has two bolts, a u, at its ends, which are capable of endwise movement, and which are connected to a ring, V, by means of links r.

The bolts to a, when in their outward position, engage in holes a in uprights secured to each side of the doorway of the ice-house, or it (the cross-piece) may be secured to any uprights suitably arranged. By this adjustable block the slide may be tilted at anyheight as the ice-house becomes filled. By the use of the yokes T the frame is tilted before it reaches the cross-piece, so that there will be space for the ice to pass beneath the cross-piece.

To start the ice to sliding when the inclina- 'tion of the rails is not sufficient to cause this which is secured to the stationary part of the cage by a cord or rope, 20, so that when the frame is tilted the free end of the lever will be moved upward and forward to bringit in contact with the ice and start it sliding upon the rails in the direction of their downward inclination.

In Fig. 3 is shown a modification of the frame S, which is merelya bar, of which there maybe more than one, pivoted to the outer end of the ice-slide, which may be placed on either end in lieu of the frame, according to whether ice is being put into or taken from the ice-house, and which, when the ice comes against it when being put on the cage, tilts over to permit the ice to pass, and is swung back by the preponderance of its lower end.

X is a block, placed between the base of the cage and that end of the rail-frame which is not tilted down to sustain that end, said end having the preponderance in the weight of ice. This block preferably consists of a number of pieces of wood, one or more of which may be removed to increase the inclination of the slide. They are held in place by yokes X.

The operation for taking ice from the icehouse is as follows: The cage being raised to the loading-place by the counter-balance, which, as stated, is'heavier than the empty cage, it is kept in this position by the brake on the drum. When the cage is loaded the brake is removed by pulling on the cord, and the cage, being heavier now than the counterbalance, descends with its load to the place of unloading, and thus the operation is continued.

When putting ice into the ice-house the weight of the counter-balance is reduced until it is less than the weight of the empty cage, and a cable, Y, one end of which is secured to the drum, is coiled around the drum several times and carried to a snatch-block, a secured to any object below. When the cage is loaded ready to be hoisted a horse or other power is applied to the drum through the means of the cable, and thus the cage is raised until the yokes T come in contact with the cross-piece U and tilt the slide, and the ice-blocks are discharged into the ice-house.

In putting ice onto the cage from the icehouse that end of the cage next to the house is held down upon the block X by any suitable means. Generally a rope is used, extending from that end of the cage downward to any object beneath to which it is attached.
