ELEVATO R ATTACH M ENT.
SPECIFICATION forming part of Letters Patent No. 592,756, dated November 2,1897.
Application filed September 11, 1893. Renewed February 13, 1897- Serial No- 623,316. (No model.)
To all whom it may concern:
Be it known that I, LEONARD ANDERSON, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented certain new and useful Improvements in Elevator Attachments; and I 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 pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to elevator attachments in which a series of traveling platforms is used, to be supported in the elevator-shaft on a line with the several floors as the elevator travels up and down the shaft.
The object is to prevent persons from falling down the shaft and to close the shaft at each floor with a fireproof partition to avoid the usual draft of the elevator, whereby fire is conducted from one floor to another or throughout the whole building through the elevator-shaft.
My device is shown in the drawings filed herewith and made a part hereof, in 'which Figure 1 is a view of the elevator, showing the position of the platforms above and below I the elevator, with the means for guiding them,
' their respective floors.
also showing the lugs on the lower platforms designed to engage with the lugs on the sides of the well to stop the several platforms at v Fig. 2 is an elevation of the device for supporting the platform. Fig. 3 is a perspective of the same. Fig. 4 is a view showing the lugs or blocks on the sides of the well. Fig. 5 is a view of a shaft and elevator with the elevator at the bottom, the several platforms above the elevator supported in position and the lower platforms assembled below and against the elevator. Fig. 6 is a similar view showing the elevator at the top and the platforms below the elevator left in their several positions.
The weights operating the lower platforms are shown in both Figs. 5 and 6.
In the several figures, A is the wall of the well.
B is the elevator.
C, D, and E represent the line of the sev-' the elevator, and c, d, and e platforms below the elevator.
-0 d, and e are weights moving up and downin the wall of the well. These weights are connected with the rope 0 C1 and 9 which runs over suitable pulleys and engages wit-h the platforms 0, d, and e. The weights are sufficient to lift the platforms and cause them to lie against and follow the elevator as it ascends. The platforms are by this construction caused to lie snugly against the bottom of the elevator as it rises until they reach their respective floors. The lower platforms are each provided with lugs c c, that engage with similar lugs a a on the walls of the shaft on the level of the several floors. The lugs on the several platforms are difierently disposed, as are those on the walls of the shaft, so that each platform will be stopped at its proper floor only. The walls of the well or shaft are provided at the level of each floor with a series of supporting devices F. The details of these devices are shown in Figs. 2 and 3. They consist of a plate f, adapted to be screwed'to the wall of theshaft, as shown in Fig. 3, and the pivoted catch f. This catch is pivoted at the bottom at f and set ofi to one side, so that its weight will cause its top to swing out from the portion f independent of the spring f. The spring may be used to givethe pivoted portion f quicker action. The catch f is provided with a supporting-lug f and its upper end at f forms a cam projecting about on a line with the lug f By the construction described asthe elevator rises the lower platform will follow the elevator until it reaches the first floor, when it will be stopped and locked with and supported on the device F, the second platform will be stopped at the second floor and similarly supported, and the third platform will be stopped at the third floor. While I have shown and described only three of these lower platforms, the number .in use will correspond with the number of floors.
As the elevator descends it will come in contact with the rounded portion f of the supports F at the upper floor and force the catches away from the platform and permit it to be carried down with the elevator, the weight holding the platform against the bottom of the elevator. hen the elevator reaches the nexit floor, the platform at I that floor will be released in the same manner and carried down, as will all of the platforms below.
The platforms ontop of the elevator are similar to those below, but 'areheld inpo'si-' tion by gravity, this force acting to hold them on top of the elevator very much in the same manner that the weights hold those below.
As the elevator ascends from the position shownin Fig. 5 the'platforms attherespective floors are picked up and lifted from the supporting devicesF and carried upwith the elevator.
As the elevator descends from'the. position shown in Fig. 6 the supporting'deviccszF, owingto :their peculiar construction, autosupporting device F rides over the edges of the platforms until the Blast or upper onel passes it, when it rfalls inward of its-own;
weight and the lug f33passesa1nder 'the-edgei and :lifts the :platform. :The :same actionisi of the platforms below the same and supporting devices'for one of said platforms at each floor, each of said devices comprising a pivoted: catch, said catch having a rounded portion with which the car is adapted to contact in its descent, substantially as described.

.and: supporting deviceslfo r one of saidplatformsat (3&0l1 flO01,'G&Ci1 of said supporting devices comprising a pivotedcatch.
In'testimony wh'ereof'I sign this specification'in thc presence of two witnesses.
