TRAVELING CRANE.

SPECIFICATION forming part of Letters Patent No. 329,219, dated October 27, 1885.

Application filed September 24, 1885. Serial No. 178,005. (No model.)

To all whom it may concern:

Be it known that I, EDWARD SAMUEL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a certain Improved Traveling Crane, of which the following is a specification. g

The main object of my invention is to construct a traveling crane which will occupy a comparatively small space, and which is more 1 especially adapted for use in machine-shops, foundries, and similar establishments, for transferring castings and other objects from one part of the shop to another, and this object I attain as more fully described hereinafter.

In the accompanying drawings, Figure 1 is a perspective view of my improved crane. Fig. 2 is a side view of the same, partly in section. Fig. 3 is an end view, looking in the direction of the arrow, Fig. 2, and also partly in section. Fig. 4 is a plan View. Fig. 5 is an enlarged sectional plan on the line 1 2, Fig. 2; and Fig. 6 is a sectional view on the line 3 4, Fig. 2, drawn to an enlarged scale.

The crane is composed of the following main parts: The supporting carriage or truck A,

post or column B,carrying the jib D, and movable hoist Ethereon, together with the top guide-carriage,G, the post B,with the jib and movable hoist, being swiveled in the top and bottom carriages, ashereinafter described. The carriages A and G travel, and are guided on single tracks 00 and y, above and below, so that the entire apparatus will occupy a compa'ratively small space, and this constitutes 3 5 one of the main features of my invention. The supporting carriage or truck A is mounted on two flanged wheels,a and a, and has attached thereto a spur-wheel, m, into which gears a pinion, m, the latter being driven by a pin- 40 ion, at, the shaft of which is provided with suitable handles, n, so that by turning these handles the crane may be caused to travelbackward or forward on its tracks. I prefer to inclose the gearing with a cover, N, so as to prevent access of dirt or dust thereto. In

the center of the carriageA is a bearing-socket, a, for the reception of a spindle or block,

- I), carried by the post B of the crane. This post I have shown in the present instance as made of a phoenix iron column, this form being preferable on account of its strength and lightness. The block b is preferably flanged, as shown in Fig. 2, and anti-friction rollers or ball-bearings are provided between the flange and the socket a to facilitate the turning of the post B in the socket. At a suitable height on this post is secured the horizontal jib D, consisting of two beams, d, of channel-iron or other suitable material,bolted through the medium of suitable blocks, d, to the post. This jib is stayed by means of suitable diagonal bracesj, extending from the upper end of the post B to the outer ends of the beams, as shown in Fig. 2. The hoist E is preferably of the type known as differential hoists, and is provided with both slow and fast movements, according to the weight to be lifted; but I do not limit myself to the use of any special construction of hoist, as any well known form may be employed. The hoist is mounted on a trolley, e, with the chains extending down between the two beams d, constituting the jib, and permitting the hoist to be traversed longitudinally on the beam to any desired position. The upper end of the post is provided with a spindle'or block, b, corresponding to that at the lower end, which spindle is adapted to a bearing-socket, g, on the guide'carriage G. The latter may be constructed of two channel-bars, h h, Figs. 1, 2, 8o 4, and 6,braced at intervals by cross-bars and by the socket g. This guide-carriage I provide, preferably near opposite ends, with wheels or rollers M for bearing against the under side of the upper rail or track, 3 and 8 5 also with wheels or rollers j, six in the present instance, to bear against the opposite sides of the rail, so that the upper end of the 'crane will be steadied and guided vertically and horizontally. Through the top of the socket 9 passes a set-screw,k, which bears on the end of the spindle b, so as to properly adjust the carriage to bring the rollers i a into contact with the under side of the rail y. The latter may be secured to the beams of the ceiling by 5 brackets, or may be secured to a series of posts, and in any case it is preferable to construct the rail below the line of belting in the shop or other building, in order that when the crane is traversed from one part to the other :00

it will not interfere with the working of the machinery.

I claim as my invention- 1. The combination of a crane with a single track above and a single track below,0n which the crane is guided and travels, substantial] y as set forth.

2-. The combination ofa single track above and a single track below with a crane-post, and carriages adapted to said tracks and having bearings for the crane-post, substantially as described.

3. The combination of the single tracks, above and below, with traveling carriages adapted thereto, and a post, B, adapted to hearings in said carriages, and having a jib, D, and hoist, substantially asset forth.

4. The combination of the upper guide rail with a traveling crane having a guidecarriage, G, provided with rollers adapted to bear on the under side of said rail, substantially as described.

5. The combination of the guide-rail with the traveling crane having a guide-carriage provided with rollers j 7', adapted to bear against the opposite sides of said rail.

6. The combination of the guide-rail with a traveling crane having a guide-carriage, G, provided with a bearing-socket, the upright post having a spindle adapted to said socket. and an adjusting-screw, 7c, substantially as and for the purpose set forth.

In testimony whereof'l have signed my name to this specification in the presence of two subscribing witnesscs.

EDWD. SAMUEL.
