HOD-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 259,613, dated June 13, 1882. Application filed May 22, 1882. (No model.)

To all whom it may concern:

Be it known that I, EPHRAIM W. WATSON, a citizen of the United States of America, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Hod-Elevators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention has relation to machines for elevating brick, mortar, and other material for building purposes, as well as gravel and earth in excavating or ore from the shafts of mines, and so on and the novelty consists in the construction of the same, as will be hereinafter more fully described, and particularly pointed out in the claim; and the object of my invention is to provide a machine adapted for the general purpose of elevating such substances as can be placed in buckets, and depositing them in any desired place at any desired height.

The figure in the drawing is a perspective .view of my improved device in operation.

A is a rectangular base or joist, of suitable size for the strength required. Onit are erected iron frames or standards B B, provided with slots 1) I), in which work the journals of the shattc of the drum 0. This drum is provided with flanges 0 c and, with the frame A, is made of such a weight as may be readily haudled by two men, so as to be moved or placed in any desired position, either inside of a building in course of erection or outside of the walls; or it can be let down into a pit or excavation as it is being sunk, and secured in place for the purpose it has to perform.

The top frame, D, is constructed somewhat similar to the lower one, it having the standards E E secured thereto, and connected at the top by the brace e.

A drum, F, is mounted on the shaft f in the standards E E, and is provided with a large gear-wheel, G.

On a shaft, h, mounted in the standards below the shaft f, is secured a pinion, H, which meshes into the gear'Gr. This shaft carrying pinion H is provided with an operating-handle, g,- or the handle may be adjusted to the shaft f, as desired.

Passing around the drums (l and F is an endless belt composed of the straps I and links 41, to which are secured at suitable intervals the hods or buckets K in which the bricks, mortar, or other material is placed for being raised to the required height for use.

A trough or table, L, is pivoted in two small standards, I Z, on the frame I), so that the hods or buckets K will discharge their contents into it to be taken and distributed where they are wanted; or hand-barrows and mortar-boards can be placed under the trough, so that the material may be discharged into them without rehandling. This trough is provided with an adjustable leg, is, having notches 6 5 7c fitting the brace m, so that the trough may be adjusted to any desired height or angle to facilitate discharging its contents. As story after story goes up, and the staging built, the top frame apparatus is also raised to cor- 7o respond, and a sufficient number of additional links and'buckets are added to the belt to make the connection.

For all the purposes of mining where shafts are sunk my improved apparatus will be found 7 5 equally available, the depth of the shaft or the height of the building not materially affecting the operation, the power always being applied at the top to draw up the load.

The empty buckets and chain or belt re turning balance the buckets and chain ascending, so that whatever length it may be necessary to have the chain. no more buckets need be used than can be readily drawn up by the power employed, and only the weight of the contents of the buckets is lifted.

Thus it will be seen that by the use of my improved apparatus for elevating brick, mortar, and other substances, as above described,

a very large amount of manual labor is saved, 0

and consequently a great saving in time and money in the building of brick structures, as well as in excavating, mining, and moving other kinds of loose material.

I do not claim the endless belt provided I drum F, gear G, pinion H, and adjustable 10 with a series of buckets for raising various trough L, in combination with the endless belt substances. I 2', having buckets K, as set forth.

Having thus fully described my invention, In testimony whereof I affix my signature in 5 what I claim as new and useful, and desire to presence of two Witnesses.

secure by Letters Patent of the United States, EPHRAIM W. WATSON. is- Witnesses The base-frame A, provided with the drum E. H. BRADFORD,

0, having flanges c 0 and the top frame, D, H. J. ENNIS.
