UNITED I srarns PATENT OFFICE.
EDWARD D. HOOKEB 'OF NEW YORK, N. Y., ASSIGNOR- TO GILLIS & GEOGI-IEGAN, ING, OF NEW YORK, N. Y., QORPURATION OF NEW YORK.
HOISTING APPARATUS.
Application filed October 22, 1923.
To all whom it may concern:
Be it known that I, Enwnnn l). Hoonnn,
a citizen of the Uni ed States, residing in the city of New York, borough of Man hattan, in the county and State of New York, have invented a certain new and useful Improvement in Hoisting Apparatus, of
which the following is a specification.
The invention relates to hoisting apparatus such as used in sidewalk hoistways and the like for raising ashcans and other light loads from the cellar to the sidewalk level. The present invention has for its objects, among others, to provide a simple yet durable and efficient hoisting mechanism applicable to the door of the hoistway and movable therewith into both operative and inoperative positions.
It has been the usual practice to mount the hoisting apparatus in the hoistway, on a column fixed therein with means operated in such hoistway for elevating the hoisting head above the sidewalk level when required. In the present invention the mechanism is so constructed and arranged that not only can itbe actuated and controlled from the sidewalk but all the parts can be mounted upon and movable with the hoistway door, where they are easily accessible for repair or otherpurposo, and the usual supporting column dispensed with thus effecting a saving of space in the hoistway and a saving in cost of installation.
Novel means are provided for supporting.
the standard for the hoisting head and holding it reliably in the operative position when thedoor is opened.
Other objects and advantages of the invention will be hereinafter set forth and the novel features thereof particularl pointed out in the appended claims. The invention in its preferred form is clearly illustrated in the accompanying drawings which, with the reference nu morals marked thereon, form a part of this specification, and in which. 0
Figure 1 is a view with the doors in sec tion and closed, the hoisting mechanism be ing shown in elevation in the inoperative position.
Figure 2 is a similar view taken at a right angle to Figure 1.
Figure 3 is an elevation with the door Serial No. 669,982.
shown open, on a larger scale than the preceding figures, the hoist being shown in its two positions, the dotted lines indicating its operative position.
Figure 1 is a similar view at a right angle to Figure '3, seen in the direction of the arrow 1 in such figure, with the hoisting head swung into a different position relatively to the standard.
Figure 5 is a detail in elevation on an enlarged scale, with a part in vertical section, and the standard shown in dotted lines.
Figure 6 is an enlarged detail in plan view, with the standard and a flange member in horizontal section, corresponding to Figure 5.
Figure 7 is a horizontal section, partly in plan view, showing in detail the pivot for the standard.
Similar reference numerals indicate the same parts in all the figures.
Referring to the drawings, 10 designates a hoistway, and 11 the sidewalk level, 12 are the doors hinged as usual to the flanged frame 18 inclosing the hoistway opening. Angle irons 14: on the door reinforce the latter and insure the desired rigidity.
The standard 15 supports the hoisting head. It is pivotally mounted at one end near one corner of the door upon the under face thereof at the side adjacent the door hinges, as shown in Figure 3, and is capable of being swung from its inoperative position, that shown by full lines in Figure 3, to the operative position shown by the dotted lines in the same figure.
The standard is shown as tubular, though not necessarily so, and as seen in Figures 6 and 7, is pivotally mounted upon a studbolt 16 screwed into the block 17 secured to the adjacent face of the door in the angle formed at a corner of the angle iron 14. As it is desirable that the standard 15 have a little play laterally upon its bolt 16, for reasons to be hereinafter made apparent, the holes 18 in the standard for the reception of the bolt are made sufficiently larger than such bolt to permit such movement. This is shown in Figure 7.
The free end of the standard 15 carries the hoisting head which may be of any wellknown or approved type. In the present instance it comprises a bifurcated frame having arms 19, in the outer end of which is a shaft 20 carrying a gearwheel 21 and a hoisting drum 22 on which is wound the hoisting cable 23 as indicated in Figure The shaft 20 is revolved by a pinion 2st in mesh with the gearwheel 21 and mounted on a shaft 25 in the arms 19 and equipped with a crank 26. The hoisting head is rotatably mounted on the standard and carries a holding-pawl 27 for the engagement with the teeth of the pinion 2e, and may be understood to be provided as usual with any suitable shifting and brake mechanism, not shown.
Extending diagonally of the door from one corner of the angle irons 1 L near the free edge of the door at 28 to a point 011 the angle iron adjacent the hinged edge, at 29, is a guide bar 30 having an angularly disposed short leg 31 at a right angle to the face of the door at the point of attachment 28, and a similar but longer leg 32 at the point of attachment 29, so that the bar liesangularly to the door-face, as shown in Figure 4. The standard 15 is inclosed between the bar 30 and the door with liberty to swing in the slightly angular space thus provided.
Secured to the door at 33 is a hinged locking-plate 3ft adapted to drop behind the standard 15 when the latter is in the operative position shown by dotted lines in Figure 3 and full lines in Figure 4. In this condition the plate 34 bears against the standard and holds it in the vertical position in the narrow portion of the space adjacent the short leg 31 of the guide bar 30. In this locked position the plate 34 rests upon the projecting flange of the angle iron 14, as seen in Figure 5.
A hook 35 secured to the adjacent wall 36 of the building or other fixed support, has a notch 37 adapted to engage the free edge of the door and hold the latter in the vertical position shown in Figures 3 and st.
lVith the parts constructed and arranged substantially as hereinbefore set forth, the operation briefly stated is as follows :Normally with the door 12 closed, the parts will be in the position in which they are shown in Figures 1 and 2. Figure 3 also shows in full lines such normal position of the standard and hoisting head, until the door has been opened. After such opening and the door being in the position shown in Figures 3 and 4, the latch or hook 35 is engaged over the top edge of the dOOr as seen in Figure l. The standard 15 is then swung upwardly from its horizontal position,that shown in full lines in Figure 3,-to its vertical position shown in dotted lines in the same figure, the standard moving between the door and the guide bar 30, until in its vertical po sition the standard is engaged by such bar adjacent the short leg 31 against which it contacts, lifting the locking-plate 34 automatically in its passage. The locking-plate then falls by gravity to its horizontal position, as seen in Figure 6, bearing against the adjacent surface of the standard, the latter then being held between the end of the lockingplate, the leg 31 and the adjacent portion of the angle iron 14. In this manner the standard is held upon three sides, and, with the aid of the hook 35 is maintained in its upright position.
The hoisting head may then be turned horizontally to the desired position over the hoistway, the cable lowered and engaged with the load to be lifted, and the hoisting operation performed in the usual manner. After the hoisting operation is completed the hook is disengaged from the door, the locking-plate 34: lifted out of. engagement against the standard; the latter is then lowered to the full-line position in Figure 3, and the door closed as seen in Figures 1 and 2. In this position the standard rests upon the guide bar 30 adjacent to the long leg 32 thereof, as seen in Figures 1 and 2, the play provided in the connection between the standard and its pivot-bolt, 16, allowing for a slight inward movement of the standard and its hoisting head fromthe wall. of the hoistway, and permitting the hoisting head to clear the sidewalk door-frame 13 in the opening and closing movements of the door.
I claim 1. A hoistway closure, a hoisting mechanism embodying a standard pivotally mounted on the under face thereof, and means for holding the standard of such mechanism in vertical position after the closure is opened and said standard moved upon its pivot to such vertical position.
2. Ayhoistway closure, a hoisting mechanism embodying a standard pivotally mounted on the under face of said closure, and a pivoted member to engage the supporting standard of said mechanism when in a vertical position.
