HOISTING APPARATUS.

Application filed June 20, 19211. Serial No. 721,158.

' '0 all fic/"1.0m t may concern.

Be it known that l, EDWARD D. HOOKER, a citizen of the United States, residing in the cit-y of New York, borough of Manhattan, in the county and VState of' New York, have invented a certain new and useful Improvement in Hoisting Apparatus, of which the following is a specilication.

The inventionrelates to hoisting apparatus `adapted for service in raising ash 'cans and like light loads from aV cellar 'to the sidewalk` Such apparatus is usually mounted in a sidewalk hoi'stway and arranged to be collapsed beneath the lioistway doors when not in use.` The main object of thc present invention is to provide simple, inexpensive and easily operated hoisting mechanism adapted for service in open sidewalk area-s, and arranged to swing vertically therein to project above the sidewalk level when required for the hoisting operation.

il., further object is to provide means for supporting the mechanism reliably to resistthe strains due to thefilifted load, and to hold the mechanism in the vertical operative posit-ion.

The invention consists in certain novel `features Vand details of construction and arrangement by which the above objects are attained, to be hereinafter described and cl ai me d.

The accompanying drawings forni a part of this specification and show the apparatus disposed in a common type of sidewalk area.

Figure 1 is a vertical section through a portion of the area, showing the hoisting apparatus in elevation and in the elevated position. y y

Figure 2 is a plan showing the apparatus in the horizontal inoperative position.

Figure 3 is a side elevation of a portion, on a larger scale, showing the supporting step for the standard of the apparatus.

Figure '-l is a corresponding front view, taken .at a. right angle to Figure 3, and partly in vertical section.

Similar reference numerals indicate the same parts in all the figures.

The sidewalk area is marked 5 and is shown as -having a flight of stairs 6 leading from the sidewalk level to the floor thereof,

as usual in 'sidewalk openings of this character.

0n the outer vertical wall 7 of the area a fixed stud 8 carrying a horizontally projecting pivot at 9 on which is mounted the Y f1() and a short arm 11.

The standard is preferably tubular for combined lightness and strength and on the outer end of' the longarm 10 is rotatably mounted the hoisting head, which may be of any preferred type and is shown as coinprising a. frame 12 carrying a drum-shaft 13 on which is mounted the winding drum lei and a gearwheel 15. A parallel pinionshaft 1S mounted in the frame carries a pinion 17 in mesh with the gearwheel 15. The ovcrhung end of the shaft 16 is squared as at 18 to receive a. removable crank'lt) by which the cable 2O may be wound upon the drinn by the operator on the sidewalk and load suspended from the hoisting hook 21 raised from the floor of the area to the sidewall; when the standard is in the vertical position shown in full lines in Figure 1. The hoisting head also has a pawl 22 a'rranged to engage the pinion 17, a brake 28 operated by a lever 24, and may have other equipments of any approved construction.

0n the outer end of the short arm 11 of the standard is a counterweight 25 shown as pivotally connected thereto by a bolt 26 cX- tending 'through the standard and the lugs 27 on the weight, so that the latter depends by gravity and hangs vertically in all positions of the standard. A bracket 28 fixed upon the wall 7 projects outwardly and carries a horizontal step 29 having raised side flanges 30 and located in the path of the 'short arm 11 so that the end of the standard will ride upon the step when 'the standard is in the vertical position. They weight of the. 'standard and its load is thus supported upon the step 29 and the pivot 9 relieved from strain in the hoisting operation. The flanges 30 guard against sidewise movements.

The step is narrow and the lugs 27 are ofl'- set as at 31, see Figure 3, to permit the body of the weight 25 to pass beneath the step 29 which with. its flanges 30 is thus inclosed between the lugs 27 when the standard is swung to the vertical position.

'ln order to hold the standard against a downward swing to the inoperative position eil after being-elevated for service, allooliingf device iseinploy'ed shown as consistlng'of" an outwardly projecting arno 32 fastened'to thewvall 7, having a seini'circular outer end'. 33 and a similarly shaped clamp`y Set` hinged,`

thereto at 35, adapted to encircle the standard. The free end of the elainp is'slot'ted" to receive a lug 36 on the arno 82 and has a hole 37 in its exposed end adapted'to' per-2V niit the insertion `of a pin, not shown, by which theA clamp 4is lockedupon kthe'stand'ard andthe latter `reliably maintained in the upfright position'. 2 v l g The counterweight Qfis slightlyoverhal- "anced the vgreater Weight of the hoisting head and'long arin 1Q of the standard, 's0' that the latter tends normally to as'snnie the inoperative' positiorn vand is supported hlor'i;V zont'allyy in such position 'by a loraeket 38' lined' on' the wall andlocated at anyeomfenf-v point between the' pivot z9' and: the'hois'tingfhead.`

'nie Operaiba rsi briefly" as' renews as:

suiiiingthe standard to` heinthe inoperative v'position shown 11n Figure 2 andin dottedl lines in Figurel, and resting on the bracket 38, it is'svvung manuallyon its pivot 9 hy"` the opera-tor to vertical position and looked in the clainp"33, 34. In this position tlieloIWer end of the standard frests ilupon the step 2 9 Vand is` confined hetneeii' theflanges" SO thereon,l and is thus 'securely supported ingu all directions, By` applying -the cranli 19 to the hoisting'head theapparatus isA in coni dition for service; A reversal of the operation again lowers thestandard tothe idle po'sition.
