Description

HENRY L. BowEns, 0E HAEEISBUEG, PENNSYLVANIA.

I Letters Patent No. 100,006, dated February 22,1870.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom t't may concern Be it known that I, HENRY L. BOWERS, of the city of Harrisburg,'in the county of Dauphin, and State of Pennsylvania, have invented a new and usefnl improvement, consisting of a Cellar-Hoist or Elevator and Gellar Stairs or Steps 7"combined,

The construction of the same, and manner of cornlbination and arrangement, l will proc-eed to describe.

'.lhe drawing represents a perspective view of the device in position for operation.

The essential feature of novelty in -this invention consists in providing a compact, convenient, and powerful hoisting machine, that will always be ready for use, and combiningthe same with cellar stairs or steps, substantially as follows:

'lhe upn'ghts or side supports B B of the stairs are made of timber sufficiently strong for the purpose. They are given a proper degree of inclination from a vertical position, and rest upon a proper foundation, their upper ends being securely fastened tolthe sill D.

rlhe said pieces B B have their front edges grooved' or channeled out, as seen at u u in the drawing.` 'l'hese grooves are .intended to act as a guide-way for the hoisting table A. v

Said table is madesubstantially as lshown in the drawing.

that portion of the frame-work of the table A that bears against the pieces 15 B' has tongues formed upon it to enter into and slide easily in the grooves in said pieces when in position, thus retaining and guiding tbe table when it is hoisted or lowered.

Upon each side of the frame of table A, at a point, s, ropes or chains b b are rigidly secured by their ends. Said ropes or chaiusare carried up over the groeved wheels nl n. These wheels are secured to the outside surtaces ot the pieces B B', and near their upper ends,in such a manner as'to permit them to turn treely upon the studs or bolts that. secure them in place.

l'he ropes or chains b b are made fast to the barrel shaft c of the winch 0r. cranerear. Said winch or hoisting gear is constructed substantially as is shown in the drawing, and consists of a lbarre-1 shaft, c, and driving shaft d, that are supported by suitable hangers.

Upon one end of the shaft c a large 'gear-wheel, o, is secured. A small' pinicn, 1', that is fastened to the i driving shaft d, meshes into the wheel o, as is shown.

Upon the opposite end of the shaft d a crank, e, is secured.

A ratchet-wheel, t', in which the click or pawl p catches, is also fastened in place upon the shaft d,in1 mediately in the rear of the crank e.'

The supporting' hangers are connected so that the entire winch is in a compact and portable form. It

is bolted or otherwise properly secured to the joists or other' suitable timbers in-the cellar, overhead, so that the handle of the crank e is accessible from theI floor. 'lhe position given the said winch should be directly opposite to or ina straight line in the rearof the cellar stairs, so that -the ropes b b will train in a correet manner.

The stepsLa a a, &c., should be set back a short distance from` the front edge of the nprights B B', so as to permit the table A to, pass their iont edges readily. t

The uprghts B B should have their lower ends let into the bottom of the cellar up to the dotted line E F. lhe lower portion or frame-work of the table A should also be sunk a similar depth, a proper' excavation heilig made to permit the same. vThis should be walled or planked upon its sides, so as to prevent dirt from falling in and obstructing the table.,

This plan of construction will bring the top of tll'f'v'er': f tableA on a line with the bottoni of the cellar. In'

fact, if it isftloored, the table will form a port-ion of the floor.. j

In using this device, weighty articles can be placed upon the table with great ease, eitherfor elevating them from the-cellar tloor to the street, or for lowering them from the street into the cellar. l v

By the operation of the winch C, the hoisting and lowering is renderedveasy and secure, as the'ratchet wheel acts as a guard to prevent slipping, and enables the operator to arrest tile-ascent or'descent of thear. ticle at any point desired. 1

The frame-work of the hoisting table A maybe provided with small wheels or rollers, with flanges, to run upon the front faces of the uprights B B'. The

grooves in the faces of the` uprights can then be dispensed with,`as well as the tongues upon the frame,A

I do not desire to claim broadly the general appli` cat-ion ofa winch to an elevator, as -I am aware that it has been so applied; but l What I do vclaim as new, of my invention, and desire vto secure by Letters Patent ofthe United States, is-

'lhe peculiar combination and arrangement Aof the,

elevating table A, stair 'uprightsB B', and winch 0,'

the whole constructed and operating substantially as herein set forth.
