Letters Patent No.,76,694, dated April 14, 1868.
IMPROVEMENT IN ELEVATORS FOR TRANSPORTING'PASS ENGERS.
an firigaulmtemh in in flan fitters gatmt an making n at figs time,
TO ALL WIEIOM IT MAY CONCERN:
I Be it known that I, JAMES S. BALDWIN, o Newark, in the county of Essex, and State of-New Jersey, have invented a new and" improved Method of Constructing Elevators used for Transporting Passengers; and I dohereby declare that; the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference mark-ed thereon, making a part of this specification.
The elevator tcwhich my improved method of construction refers, is one which has been in use forfmany years in a, partially-developed shape.- It isdescribed in Overmans Metallurgy, fifth edition, page 98, and in the 'Mechanics Magazine for March or April, 1867, (the exact pagecould not be ascertainedat the timetof writing;
the quotation is from memory, no copy of the magazine bein'g accessibla) as well as in other works of a similar character. As described in said works, and as now operated, the said machina'onsists of two sets of platforms, arranged at'equal distances from each other, vertically. Oneset has-a constant reciprocating motion equal in amplitude to the distance between two platform's 'the other set is either stationary or has 'a similar motion.
Now, inadapting this elevator to buildings of the ordinary description, which I am'enabled to do .by improve.
nients not herein described, I find it necessary to give the platforms a differential movement adapted to the varying height of the difi'erent stories. I i I Figure I represents the six floors of a building A B C DE F, at varying distances above each other, as hown by the figures, and A B C DEi F are the corresponding floors or platforms of the elevator. S S S,
' in the several figures, representsthe framework of thc 'samc. Now, if this framework is raisedand lowered, by .appropriate machinery, a distance corresponding to that between any two floors, then, owing to the variation in the distances between the'several floors, it must cither exceed or fall short of said distances, as the case may be. To remedy this, I give th'emain frame a movement corresponding to the interval which occurs most frequcntly, as, in the present case, ten feet between A, B, and G; and to enable the'other floors, D E If", to gain the distancewhich they would otherwise fall short, l mount each of them in a frame, T T T T, Figures I, II,
and III, oapableof receiving an independent motion inside the main frame S S S S, and by the use of the Windlass W A", shown in front and side elevation in Figs. II-and III,- supply the deficiency in their movement. This windlass is provided with the cord G G, firmly fastened below, and the cord N wound round the axle A",
and fastened to the movable interior frame T T T T Now, it the main frame receives iin upward movement,
as indicated by the arrow X, the cord G G, being fastened at the lower end, must unwind from and impart a rotary motion to W, winding up the cord N on the axle and drawing up the frame T and its floor, thus giving the requisiteaddition to the'moti'on of the main frame .Whcn the main frame is lowered, the weight of T T T T will cause N to unwind and G G'to be wound in again.
lflthe floors D E F, Figure-IV, are capable of an independent motion, and are suspended from a conepulley overhead, their motions will vary with the diameters of said pulley, and by the proper construction of 'said pulley, a reciprocating rotary motion imparted to it will be followed-by a reciprocating vertical motion of live suspended platforms. The interior frames T T T are not shown in Figure IV, their use being presupposed.
What Iclaim as my invention, and desire to secure by Letters Patent, is'
. The elevator for buildings having floors of varying height, constructed substantially in the manner set forth I JAMES S. BALDWIN.
