Description
UNITED STATES PATENT OEEICE.
OLIVER P. HATFIELD, OF NEW YORK, N. Y.
IM PROVED ELEVATO R.
Specification forming part of Letters Patent No. 34,572, dated March 4, 1862.
.To all whom it may concern:
Be it known that I, OLIVER P. HATEIELD, of New York, in the county and State of New York, have invented a newand Improved Elevator; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective View -of the platform, frame, &c. Fig. 2 is a view of the upper guide-arm, and Fig. 3 is a view of the lower'guide-arm. Fig. 4 is a front elevation. Fig. 5 is a side elevation, and Fig. Gis aplan, of the elevator and guide-posts complete. Fig. 7 is a top plan, and Fig. Sis a side elevation, of the upper guide-arm. Fig. 9 is a bottom plan, and Fig. 10 is a side elevation, of the lower guide-arm, &c.
The nature of my invention consists in constructing an elevator having beneath the platform upon which the load is placed a framework so arranged as to throw the pressure of said load upon vertical guide-posts placed upon one side only of said platform, and at the same time preserving the platform in a horizontal position, thus dispensing with the guide-posts, pulleys, chains, &c., upon the other side, and making the space through which the platform passes available for other purposes when the elevator is not in use.
To enable others skilled in the art to make and use my invention, I will proceed to describe its cons truction and operation.
The frame A, Fig. l, is constructed with downward braces a b, so as to concentrate the pressure against the guide-posts c d at d, and is tied together strongly by the framing, so as to receive a tensile support at e. This support is given by the guide-arm B, Fig. 2, having friction-rollers i fm, running upon the back of the guide-post C, as shown. The guide-arm at ol, Fig. 1, is shown more at large at D, Fig. 3,showingthat the pressure against the guide-post C is received upon the friction-roller n.
In order that the guide-posts c d may sustain both the tensile and the compressive strain they are constructed in the form of the letter T, as shown at o, Figs. 2 and 3, and braced to the wall or other support by braces s, Fig. 2, which are secured to the wall or other support, and the guide-post O secured to them, as shown, by nuts. I propose in some cases to substitute a continuous bar between the guide-post O and the wall (or other support) instead of the braces s, or in addition to them. The friction-rollers t' and m, Fig. 2, are set apart wide enough to pass which is of the ordinary construction, hav-.
ing wheel and arbor, pinion, crank, frictionwheel, ratchet, and catch, &c. The chain or rope being secured to the platform framework atv u enables the platform p to be raised iiush with the upper iioor f without the appearance of any of the other parts above said Iioor, and at the lower iioor g a pit h is constructed to receive theframe-work, so that the platform p may lie Hush with the iioor g in the same' manner; but I also propose to extend it through more than one story, to place it in vaults under stoops and sidewalks, and in other places.
I propose to apply the invention also to the elevation of dumb-waiter boxes by constructing said box or shelving upon the platform.
I propose in some cases to make the framework under the platform of iron, and in all cases to construct the several parts of a size corresponding with the strain to be put upon them.
I am aware that elevators have been conlstructed supported by chains, guide-posts, and pulleys at each corner, and dumb-waiters supported by guide-posts at each corner.
or two guide-posts near the center, and a rope above the center of the box of shelving; also, that elevators have beenmade to ascend and descend inclined planes, and buckets made to ascend upon endless chains; but
I claim as my invention- The construction of an elevator or dumb- Waiter supported wholly upon one side, ascending and descending in a vertical course, substantially in the manner described.
