UNITED STATES PATENT OFFICE CEYLON ISBELL AND SYLVANUS M. GILLETT, OF HOMER, NEW YORK; SAID GILLETT ASSIGNOR OF ONE-HALF OF HIS RIGHT TO SAID ISBELL.

ICE-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 445,525, dated January 2'7, 1891.

Application filed October 13, 1890- Serial No. 367,977. (No model.)

To all whom it may concern:

Be it known that we, CEYLON ISBELL and SYLVANUS M. GILLETT, residing at Little York, town of Homer, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Ice- Elevators, of which the following is a specification, reference being had therein to the accompanying drawings.

16 This invention relates to hoisting apparatus, and is specially applicable to ice-elevators, but may be used for other purposes.

The object of the invention is to produce an elevator which may be run by horse-power,

and in which the horse may move continuously in one direction,while the cars or loads are alternately drawn up an incline or slideway.

A further object is to improve horse-power 2o elevators in various particulars.

Figure 1 is a side elevation of an inclined way and a horse-power in proximity thereto. Fig. 2 is a plan of the way. Fig. 3 is a plan of the horse-power and rope-reels, and Fig. 4

' a side elevation thereof.

The numeral 1 indicates a track or slideway. For an ice-elevator this slideway will be at the side of a river or pond, the lower end extending into the water. The upper end 0 may be supported by uprights 2, which uprights may be the side of a store-house or icehonse, or the uprights may be alongside a track or road, so that ice may be loaded into cars or wagons. The lower end 3 of the way should be under water, so that ice-blocks can be readily floated over either of the two tracks 4 and 5 of the inclined way. A rope or cable 6 passes over pulleys, as '7, at the head of the incline and extends along the ways 4 and 5,

0 and so around sheaves 8 and 9 at or near the foot of the incline. Cars or grappling- crabs 10 and 11 are attached to the rope at such distance apart that one of the cars or crabs will be at the head of the incline 5 while the other is at the foot of the incline 4, and by a reversal of movement of the rope 6 one car or crab will be drawn up one incline while the other is moving down the otherincline. The

tracks or ways 4. and 5 are preferably broken away at the top of the incline, so that blocks of the ice drawn up by the crabs l0 and 11 will slide up the bars 12 and fall through the open ing 13 at the head of the incline. Of course the blocks may be pushed off the upper ends of the incline, and if cars be used instead of crabs the cars may be made to dump themselves at the head of the incline in usual manner. The middle portion of the rope passes round the pulleys 8 and 9. The two ends are carried down around suitable pul- 6c leys, as 15 and thence the two ends of the rope are conducted to the reels 20 and 30 of the horse-power 19. One end of the rope passes round suitable guiding-sheaves 15 to the horizontal sheave 16, which guides the rope to the hooks 22 of the reel 20. The reel 20 has the end of the rope attached, as at 23, and may have a considerable length of the rope wound on the reel, so that the position of the horse-power may be shifted, the rope on the reel being paid out or wound up to correspond. The reel 20 has its central bearing on the tubular post or axle 31 and is free to revolve thereon ineither direction, save as hereinafter described. The reel is supported 7 5 on a wear-plate 32.

A sweep 4.0 is swiveled on the post or axle 31, and a horse is attached to this sweep to travel in a circle around the reels and turn the sweep, as usual in this class of horse-powers. A button, or clutch 4.1, pivoted on the sweep 4.0, has a pin or abutment 42 projecting upwardly in position to engage one arm of the reel 30 when the button is turned in the proper direction by means of hand-lever 4.4; I but said pin will ride past the end of the arms of the reel when the lever 44 is turned in the other direction. The other abutment or pin 43 projects in the opposite direction and bears similar relation to the arms of-thereel 20, so 9 that the button 41 may be turned to drive either the reel 20 or the reel 30 with the sweep 40, but not both reels, and when one reel is in engagement with the button on the sweep the other reel is released and free to run backward. The other end of the rope 6 is carried to the center of the horse-power up through the hollow axle or spindle 31, and so over suitable sheaves at 50 50 to the end of a bar 51, which brings the rope outside the 10 hooks 36 on the arms of reel 30. The bar 51 is rigid with the axle and may extend in any direction. \Vhen button 41 is turned, as in Fig. 3, to carry round the reel 30 with sweep 5L0 by engagement of the pin 4:3, (one end of the rope 6 being secured to the reel 30,) the reel will wind up rope on itself, thus drawing up the car or crab 11 to the top of the incline, and at the same time by the rope passing round sheaves 8 and 9, drawing down the other car or crab 10 to the bottom of the in cline and causing reel 20 to run backward and pay out rope. When the car or crab 11 has got to the top of theincline and delivered its load,the' button 41 is swung to one side by the driver, thus releasing reel 30 and immediately engaging reel ZOby means of the other pin 42 andthe rope movement is immediately reversed, the crab 10 being drawn up and crab ll drawn down, the reel 30 running free to pay out rope. Thusthe horse moves always in one direction, while the rope can be reeled up or paid out in, either direction under control of the button 451. i

It is desirable that the sheaves 8 and E) be so far from the base of the machine as togive opportunity to move the ice-blocks in front of the crabs.

For convenience in loading, the crabs may have automatic grapples, as is common in ice-elevators.

The rope is conducted to the center of the horse-power and so out to the end of bar51 to avoid entanglement of the rope. The bar 51 may extend in any direction from the center of the machine, but will preferably not extend in the same direction from the center as pulley 16.

It is understood that equivalent-s are covered in the claims, and that the construction may be modified within reasonable limits.

The elevator may be used in raising coal, stone, and other materials as well as raising ice.

iVhat we claim is- 1. In an elevator, the combination of a double track or slideway set at an incline, a rope extending lengthwise of the slideway and around gu iding-pullcvs at the bottom and attached to a car or crab on each slideway, and a double reel to which the ends of the rope are attached, one reel being free to unwind as the other winds on the rope, all substantially as described.

2. The combination, with an elevator-way of the character described, of a winding device consisting, essentially, of two reels on a vertical axis, a sweep between the reels, and a clutch connected to the sweep in position to engage one or the other of the reels, substantially as described.

3. The combination, with an elevator-way of the character described, of a winding device consisting of two reels and an intermediate sweep, and a turn-button pivoted on the sweep an d having an abutment above and below in position to engage one or the other of the reels, substantially as described.

4. The combination, with the elevator having a double way and an elevator-rope, as described, of the winding device consisting of a double reel and intermediate sweep on a hollow central axle, one end of the rope being wound on the lower reel by direct engagement, the other rope end passing up through the axle and out to the outside of the upper reel, substantially as described.

5. The inclined way, the horse-power having a hollow central post and two reels and a sweep pivoted thereon, a rope connected to one reel and extending around guide-pulleys to a crab on the way, thence around pulleys and so back to the horse-power, thence through the central post and out abar to the outside of the second reel, and a clutch on the sweep in position to couple the sweep to one reel, but not to both at the same time, all substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
