HOIS'IING- APPARATUS.

Application filed December 4,1920. Serial No. 428,248.

1 '0 all whom it may concern:

Be it known that I, Trroafiis F. HUNTER, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful improvement in Hoisting Apparatus, of which the following is a specification.

This invention relates to improvements in hoisting apparatus, and particularly, to that class of apparatuswhich is used in building construction. i

One of its objects is to facilitate the transfer of material from the interiorof a build ing to be erected to the carrier of the hoist ing apparatus and to successive floors of a building under construction. 7

Another object of the invention is to provide reinforcing structures for the uprights of the hoisting apparatus and to arrange these reinforcing structures at different elevatio-ns of the uprights in such relation to the floors of the building that the transfer of material from the floors to the carrier of the hoisting apparatus will not be interfered with by the reinforcing structure.-

It is also an objeot'of the invention to provide a readily removable platform which can be placed on the carrier of the hoisting apparatus so as to facilitatethe transfer of material from over this carrier.

It is, furthermore, an object of the invention to combine with the platform to be placed on the carrier a platform extension communicating between the hoisting apparatus and the building itself, to permit the use of wheel-barrows and the like for the transfer of material from the interior of the building.

It is also an object of the invention to combine with the hoisting apparatus a readily removable skid or loader through which the material from the carrier can be automatically discharged into cars on other transporting means placed adjacent the hoisting apparatus.

Another object of the invention is to com bine with the removable loader means for deflecting during the transfer from the hoisting apparatus to the car or the like the articles which pass over the loader so that they will be automatically placed in proper position for entering the car'or the like,

thereby accelerating the operation of load- With them and. many: other objects in view, embodiments of the invention are described in the following specification in which reference is made to the accompanying drawing.

' In the drawing:

Fig. l is a perspective view of the hoisting apparatus, the reinforcing elements, and platform.

Fig. 2 is a side elevation of the carrier with the removable platform in place;

Fig. 3 is a perspective view of the removable platform;

Fig. 4: is a side elevation, partly in section, of the hoisting apparatus combined with the loader;

Fig. 5 is a sectional elevation on line 55 of Fig. 4:;

Fig. 6 is a partly horizontal section through the hoisting apparatus and partly a top plan view of the removable loader with the deflecting device shown thereon; and,

Fig. 7 is a view similar to Fig. 6, showing a modification of the deflecting means.

The uprights 1 of the hoisting device are provided with guiding grooves 2 in which portions of the carrier are adapted to slide vertically.

The floors of the building are diagrammatically indicated at 3, and braces 4 may serve for maintaining the uprights 1 in proper position, with respect to the wall of the building, said braces being preferably attached to the outside of the uprights 1 and connecting the same with portions pertaining to the floors 3.

In order to brace this structure without, however, interfering with the transfer of material from the interior of the building to the carrier, bracing elements 5 in the form of diagonal struts are interposed between opposite uprights 1. The upper ends of these bracing elements are located adjacent the lower surface of the floors 3, so as to permit of the transfer of material carried on the floors from the interior of the building to the carrier. The bracing elements 5, being located adjacent the ceilings of the various stories are relatively high above the floors on which the men walk.

The carrier structure, itself, may be of any construction and may comprise the upright guiding structure 7 which is suitably braced and the side bars of which may travel in the grooves 2 of the uprights, horizontal members 8, the slanting top 9 composed- Qf article entering the door of the transporting device 50 and thereby facilitating the 1 loading operation of these articles.

the spirit of the invention, audit is not the intention to limit the invention to the details as shown, but to include allrmodifications thereof, constituting departures Within the scope of the invention, as defined by the appended claims.

I claim:

1. In combination with a hoisting apparatus having uprights and. a carrier traveling along the uprights, said carrier being provided with a supporting surface slanting in direction toward the plane of said uprights, a detachable platform adapted to be placed on said carrier and including members located in a substantially horizontal plane with respect to the uprights.

2. In combination with a hoisting apparatus having uprights and a carrier traveling along the uprights, the carrier having a supporting surface slantingin direction towards the plane of said uprights,

a detachable platform having a slanting substructure adapted for engagement with the slanting supporting surface of the carrier,iand a horizontal superstructure secured to said substructure.

3. In combination with a hoisting apparatus having uprights and a carrier v traveling along the uprights said carrier bea, ing provided with a supporting surface slanting in direction towards the plane of said. uprights, a detachable platform, including a substructure which consists of vertical members, horizontal members extending from the top of said vertical mem bers, braced connecting elements between the free ends of said horizontal and vertical members, and a plurality of boards secured to the horizontal members.

l- In combination with a hoisting apparatus having uprights and a carrier with i a slanting portion traveling along the uprights, a detachable platform adapted to convert the slanting portion of the carrier into a horizontal surface, and means for locking said detachable platform against shifting movement on the carrier.

5. In a hoisting apparatus having uprights extending through several floors of a building and. a carrier traveling along said upri hts, bracing elements connecting said. uprights; said bracing elements being fixedly connected with said uprights at a substantially large elevation from the floors of the building and additional braces securing the uprights to doors of the building.

6. In a combination with a hoisting apparatus having uprights associated with several floors of a building and a carrier traveling along, the uprights, the carrier having a slanting surface portion, a detachable platform adapted to be placed on said slanting surface portion and supplementing said carrier to present a horizontal surface, and an additional platform removably attached to the floor of a building adapted to permit the passage of men and transportation devices from the interior of the build- .r ing to the detachable platform.

In combination'with a hoisting apparatus having uprights and a'carrier traveling along the uprights, a loader including slanting. members between which the carrier may travel, whereby in the passage of the carrier through the plane defined by said slanting members articles projecting beyond the ends of the carrier are automatically transferred to said slanting memhere.

8. In combination with a hoisting apparatus having uprights and a carrier traveling along the uprights, a loader consisting of slanting members braced to the uprights, and a deflecting element functionally associated with said slanting members adapted to deflect articles whose ends project beyond the slanting members from a direction transverse to said members to a different angular direction.

9. In combination with a hoisting apparatus having uprights and carrier traveling along the uprights, a loader having slanting members parallel to each other and braced to the uprights near the lower part thereof, said slanting members being sulfciently spaced from each other to ermit the carrier to travel through between the same, guiding elements secured between said slanting members and parallel to the same, and a deflecting element associated with said loader and adapted to deflect articles pro jecting beyond the slanting members from their position. i

10. In combination with a hoisting apparatus having uprights and a ca rier traveling along the uprlghts, a loader consisting of slanting members secured to the uprights and resting ture at their lower ends, and an additional skid pivotally connected with the lower end of said slanting members.
