To alt/whom it may concern y u Be ib known that I, EDWARD D. HOOKER, a citizen ofthe, United States, vresiding in lthe city of New York, borough of Manhattan, in the county and State of New York, have invented a certain new and useful Improvementin Hoisting Apparatus, of which the following is a speciiication. i

This inventionY relates to hoisting machinery such .asisJ used in sidewalk hoistways,"and -the like, `and it has for its obeflicient hoisting device readily applied to the hoistway with the parts so arranged that 'theclosure for the hoistway will be yopened by direct contact therewith of opening means on which the hoisting head is mounted. The hoisting head is carried by vertically movable, bodily-movable, means in contradistinction to being carried by.y a telescopic support, issuing from a sustaining ycolurnuat the bottom of the lioistway. Thepresent improved hoisting apparatus of this general type comprises vertically-movable means r guided at opposite sides of the hoistway, its

upper end adaptedto contact' directly with the movablymounted closure, the hoisting mechanism or head being carried by such closure-opening means. `The closure is ar-` ranged to .return to its closed position by gravity. Another important object is to provide means for automatically engaging 1he closure andholding the same reliablyV in the open position.

Other objects and advantages of the in- Avention will hereinafter appear andthe novel features.-thereoffwill be specifically defined by the vappended claims.

The invention-in its preferred form is clearly illustratedy in the accompanying drawings, which, with the reference numerals markedv thereon, forma part of this specification and in'which-e A, .1

Figure 5 is an enlarged sectional detail of the guiding means shown at the left in Figure 2.

Figure 6 is a similar View showing the means for holding the doors in the open position.

Figure 7 isa vertical section, partly in elevation, showing a detail of the door-opening mechanism. Y f Y Like numerals of reference indicate like parts throughout the several views.

kReferring tothe drawings, 10designates the hoistway, 11 the sidewalk level, and 12 the closure for the hoistway, in the present instance shown as composed of two doors hinged in any suitable manner, andL adapted to assume closed positions by gravity when not held open by the means which carries the hoisting head, or otherwise. v 1.3 is the metallic framing about the opening to the hoistvvay, to which the doors' 12 are hinged, and may be understood to be of the usual or any approved construction.

guita-bly secured within the hoistway, near the bottom of the same, as seen in Figure 1, is a bracket 14 ixedly fastened to the wall 15 of the hoistway and this bracket serves not only for the mounting of the mechanism for elevating the door-openingmeans but also as a guide Vfor suchmeans.

16 is a shaft supported in the bracket14 and carrying'a gear-wheel 17 which is in mesh with a pinion 18 on the shaft'l) also supported in the bracket 14. 2O is a crank on the shaft 19. i

On the shaft 16is a wheel 21 the periphery of which is provided with spurs 22 which are adapted to cooperate with the series of holes 23 in the long depending leg24 vof the arched hoist-supporting and door-opening member. As seen in Figures 1 and 4 the bracket 14 serves as a guide for thisleg 24. The oppositeshorter leg 25' of this hoistcarrying member is guidedin a gu1dev26 isf/'aen lli mounted on the wall oi the hoistway, as eeen in Figure 1. yl`he arched upper end E27 et' the ladet-carrying member is designed to contact directly with the under Sido ot the closure and raise the name as the said inember rained. and upon thin` member near its upper end beneath the arch is mounted 'die hoisting head which may be ot any of the well known or approved forms. It comprises the gearwhecl 2S carried by a :.hat't 2S) Supported in the arms 80 ot a 'frame carried by the vertical standard or the like Si which is mounted to partially revolve iu the bearinge 232 on the bracket 33 fast to the thinge l' ot the leg* Q-t, all as seen in Figure 1. 3ft is a drum indicated in dotted lines, on the shaft 2S) upon which is wound a cable 35 carrying the hoisting hook 3G. 37 is a pinion meshing with the gearwheel QQ: said pinion beingl mounted on the shaft 3S supported in the arms lo and upon which the crank handle 39 Secured.

In order to guide the leg 2l at a point near the top ot the hoiatway and impart the required rigidity thereto to sustain it in its` movements and to enable it to withstand any strains put thereupon, the Stem itl ot thif#y leg has riveted thereto the angle irons -l-l and 42, See Figures 1-, 5 and t3. and to the training lf3 about the mouth ot' the hoistway is riveted at #i3 the angled member il to the tace ot which are secured at the memhere` 4G. the flanges t7 oi" which receive and serve as guides tor the cooperating tlangen` 4S ot the angle irons it aud -l-Q, all as seen in Figuresl 2 and 49 an angled member or guard having one limb 5t) et ured to the leg lal-` and cooperating therewith in the guard member 5l. See Figure The adjacent cndn or edges et theae two members overlap and conatitute guard gates disipoeed at the iside ot' the hoistway at a right angle to the door@V lf2. an Seen in Figure l. The margin ot the gate fil opponite to that which overlaps the fixed gate 45), is joined to the member 52 by a Spring hinge connection all. Fee Figure the construction being auch that the Swing gate .il will normally be closed against the hxed gate ntl but readily yielding to 'torce when the ash can or other load is placed there` againttto move the name trom the hoistway. The member 52 ia Secured to the short leg in any suitable manner.

(')n the Stem :il: of the Short leg and eX- tending downwardly thereon 'trom the Spring oi' the arch a short distance. are anglo irons aimilar to thoao marked all on the long leg El. As before Stated the angle irons Lil Serve with the member `it and bracket ll to guide the leg 2i in its vertical movements, and the angle irons il with the angle `irene perform the additional function ot automatically holding the doors 1Q in the Vertical open position. (ln the 'tree margin ot each doorr` in line with the moyementa ot the angle irons l1 and 55, are Secured hoolelike projections on atlapted to overlap both the tlangee1 ot such iroin,l and engage therewith an the toorn are lifted and swing into the vertical open position, and maintain such engagement during the period in which the doors remain open.

rlhe parts being constructed and arranged substantially as above described, the operation, briefly stated its as follows :MNormally the doors l2 are closed and they hoist supporting' member with its attached parts are in the dotted line position seen in Figure l. 'When it iS desired to use the hoist the opera tor granps the crank handle 2() and turns the same to rotate the aha'l't 1S). the pinion 18 meshing with the gearwheel 17 turns the wheel El and its spun` engaging in the holes Jil in the leg 2l raises the latter with the hoisting head. When the arch 27 Strikes the doors` the latter willbe opened. When the parte have been raised a Sutlicient distance the same are stopped, being held against retrogriule movement in any Suitable manner, and the doors held stationary in the open position by the engagement oi the angie irons il and with the projections 5G. Then the lable and its hook 3G are lowered. the can or other object to be raised engaged with the hook. and the crank handle 89 turned to wind the cable upon the drum. and when the can is; at the proper height the can is pushed against the guard gate al. the latter opens. and as soon as the can has passed through the opening the gate in closed by means ot' ita Spring hinge. The hoist is then lmrered to the dotted line position in Figure l, the doors 12 automatically closing.

lt will be noted that the bucket hoisting mechanism carried by the upper end ot the hoist-carrying member is entirely independent ot' and in nowiee associated with the means it'or raising and lowering said member: furthermore when the hoist-carrying member iS raised to its operative position it is there retained until all ot the hoist-` ing has been done, and it is not necessary to raise and lower the hoist-carrying member with each operation oi raising and lowering the bucket.

Modifications in detail, proportion ot parts etc., may be resorted to without de parting from the Spirit ot' the invention or sacrificing any ot its advantages.
