Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed February 6, 1905. Serial No. 244,451-

To all whom it may concern:

Be it known that I, WILLIAM BLACK, a citizen of the United States of America, residing at Rices Landing, in the county of Greene and State of Pennsylvania, have invented certain new and useful Improvements in Cages for Mine and Elevator Shafts, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in cages for mine and elevator shafts, and more particularly to that type of cage which is employed for conveying cars.

The invention has for its object to provide a novel form of cage entirely constructed of metal.

The cage as constructed by me is particularly adapted for mine-shafts for conveying mine-cars from the different rooms of the mine to the top of the shaft, and I have provided novel means whereby the loiig timbers and girders which are used in mines for props can be readily hauled upon my improved ca e.

WVith the above and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described and then specifically pointed out in the claims, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which- Figure l is a side elevation of my improved cage. Fig. 2 is a top plan view thereof partly broken away. Fig. 3 is a front view of my improved elevator-cage.

To put my invention into practice, I have constructed my improved cage of structural steel and iron, and some parts of the cage are formed of standard material, while other parts are formed of special castings. The base of the cage consists of two sills l l, which are secured together by a pluralityof transverse braces 2.` These braces are formed of sections of pipe cut the desired length and threaded upon each end, whereby theymay be interposed between the sills l l. The floor of the cage is formed of a plurality of substantially channel-shaped plates 3, the depending iianges 4 of which are pierced to permit of the braces 2 extending therethrough Mounted between said plates upon the braces 2 are tracks 4 4 upon which travels the car to be hoisted.

The reference-numerals 5 5 indicate the main frames or bolsters of myimproved cage, and these frames are adaptedto be connected to the sills v1 l by a plurality-of verticallyarranged braces 6, which are similar in construction to the braces 2, heretofore described. The frames 5 5 are provided with transverse braces 7 7, to which are hinged, as indicated at 8 8, plates 9 9, these plates forming the top or roof of my improved cage. The frames 5 5 are provided with horizontallyalined openings l() 10. Supported by the transverse braces 7 7 and the casing 11 are two top plates 35 35, which, together with the platesQ 9, form the roof or top of the cage.

It will be observed that I have constructed my improved inine-cage entirely of metal, and the use of bolts and nuts is dispensed with, wherebyit will not be possible for any part of the cage to become disconnected and cause an accident.

Comparatively few parts are used in the construction of my improved cage, and I do not care to confine myself to the use of sections of pipes or tubing for braces, as tie-rods can be conveniently used in place of the tubing.

What I claim, and desire to secure by Letters Patent, is-

1. A cage of the type described comprising sills, flooring supported by said sills, said iiooring consisting of channel-shaped plates and braces extending through the depending edges of said plates, through said sillsa track supported on said flooring, bolsters from which the sills are supported and vertical and oblique braces connecting said holsters With said sills.

2. A cage of the type described, consisting of parallel sills, transverse braces securing said sills together, a iioor composed of channelshaped plates, said braces extending through said plates, tracks mounted on said iioor, bolsters arranged above the sills, vertical braces connecting said bolsters to said sills, transverse braces connecting said bolsters together, and plates hinged to said lastnamed transverse braces and constituting the roof of the cage.

3. A cage of the type described, comprising i metallic sills, transverse braces connecting said sills, a metallic flooring mounted on said braces, metallic bolstei's, vertical braces, an-

1o sills and passing through the depending flanges of said channel-plates, and tracks arranged between said channelplates, said braces extending through said tracks.

In testimony whereof I aflix my signature in the presence of two witnesses.
