UNITED STATES PATENT OFFICE.
JOHN HALL, OF ORESTON, IOWA.
lCE-ELEVATO R.
SPECIFICATION forming part of Letters Patent No. 402,589, dated May '7, 1889.
. Application filed December 4, 1888. Serial No. 292,649- (No model.)
To all whom it may concern:
Be it known that I, JOHN HALL, a citizen of the United States, residing at Oreston, 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 the invention, such as will enable others. skilled in the art to which it appertains to make and use the same.
This invention relates to an apparatus for elevating ice; and itis designed as an improvement upon the invention shown and described in the Letters Patent granted to me Novemher 6, 1888, No. 392,203.
The improvements will be fully understood from the following description and claims, when taken in connection with the accompanying drawings, in Which- Figure l is a side elevation of an ice-elevating apparatus embodying my invention, showing the same in a position at a lake.
Fig. 2 is a front elevation of the same; and- Fig. 3 is a sectional detail view of the extended platform.
Referring by letter to the said drawings, A indicates the main frame having the inclined ways B and the delivery ways 0, all of which are of the construction illustrated in my Letters Patent above referred to. Mounted in this main frame at the upper portion thereof is suitable mechanism for driving an endless elevating-chain, which is providedv at suitable points with cross-bars and hooks or dogs for engaging the cakes of ice to be elevated. According to my present improvements I have extended the elevating-way, so that it may be carried a sufficient distance into the lake or othenplace from which ice is to be obtained.
D indicates a platform which is adapted to be raised or lowered, as will presently be described.
E indicates uprights, there being preferably four employed. These uprights are designed to adj ustably support the platform D, and bear at their lower ends on the bed of the lake; These uprights are provided at their upper ends with cross-pieces M, having threaded apertures to receive threaded rods F, which are secured at their lower ends to the platform D, and are provided at their upper ends with handles G, or other suitable means for turning them. It will thus be seen that the platform may be raised or lowered to any desired point or altitude with respect to the surface of the water, so that the ice as it is cut may be conveniently delivered thereon. This platform, which may be eX- tended to any suitable point in the lake, is
connected with the main frame or way by a link, II, and it is obvious that two or more links may be employed, according to the distance at which it is desired. to anchor the platform.
Journaled in the foremost set of uprights, E, and above the platform, is a sprocketwheel, I, and in the opposite or rear set of uprights is journaled a roller, K, which is arranged a suitable distance above the platform to allow the endless elevating-chain to pass beneath itrwith ice thereon.
The endless elevating chain L, which passes from a shaft or roller in the upper portion of the main frame, passes out above the platform in the lake and over the sprocketwheel I, journaled in the uprights thereof,
thereby carrying the elevatingchain to a suit-able point within the lake, and where it is more convenient to have the lugs on the chain engage the blocks of ice to be elevated.
Having described my invention, what I claim is 1. An ice-elevating apparatus comprising, essentially, a rigid inclined frame, aplatform at the lower end thereof adapted to be let into a lake and adjustably connected with said rigid frame, the platform being supported on uprights which carry threaded rods for raising and lowering said platform, substantially as specified.
2. The combination, with the main frame, of the platform, the uprights having threaded apertures at their upper ends, the threaded adj usting-rods secured at their lower ends to 5 JOHN HALL.
