TRAVELING CRANE.

SPECIFICATION forming part of Letters Patent N 0. 673,622, dated May '7, 1901.

Application filed April 19, 1900.

To all whom, it may concern.-

Be it known that I, EDWARD Y. MOORE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Traveling Cranes, of which the following is a full,clear, and exact description, reference beinghad to the accompanying drawings.

My invention relates to overhead traveling cranes of bridge form movable along supporting-tracks.

The object of the invention is to produce a crane of this type which shall be strong, compact, and durable and at the same time be cheap and simple in construction, so as to expedite the assembling of its parts, being composed largely of ordinary rolled forms of metal.

In its general construction the crane consists of a bridge supported by a truck at each end, which trucks run on suitably-supported parallel rails. Upon the bridge is :a track transverse of the supporting-rails and upon which the usual carriage operates.

My invention resides in the construction and arrangement of the end trucks and the means of securing them to the bridge and of bracing the crane, allof which will be more fully described in the following specification and definitely set forth in the claims.

Referring to the drawings, which fully illustrate my invention, Figure 1 is a perspective view showing the crane complete. Fig. 2 is a plan of the same with the carriage removed and with parts of the truck and bridge shown in section. Fig. 3 is a sectional elevation taken on the line 3 3 of Fig. 2 looking toward the right of that figure, part of the truck being broken away to show its interior. Figs. 4, 5, 6, and 7 are vertical sections on the correspondingly-numbered lines of Fig. 3 looking in each case toward the right.

Referring to the parts by letters, A A represent the track-support for the crane; B B, the trucks; 0, the bridge, and D the carriage operating upon the bridge. I

The trucks B B, which carry the wheels I), as hereinafter described, are formed of a pair of channel-beams b 19 set with their riage D travels.

and bolted together through suitable distanceblocks b b The bridge 0 is composed of a pair of girders or I-beams set on edge and carrying on their upper surface rails c, on which the car- Near each end of the bridge there are made through the vertical webs of the girders openings of the same shape and I position as the section of the channels forming the truck, and through these openings the channel members I) I) extend. The trucks and bridge are secured together by angle members or clips F, which are riveted to the inner side of the bridge and-bolted to the trucks by the bolts E, extending through the channel members of the truck and taking nuts e outside the outer member.

The construction described makes a very simple and at the same time rigid connection A tie-rod H may be provided across the I-beams of the bridge, near its ends, to additionally brace it.

To give additional stiffness to the crane, I secure on each side of the bridge, parallel therewith, an inverted channel member G. The webs of these channels are horizontal. The inner side flange is riveted directly to the I-beams of the bridge, and the ends lie be neath the upper flange of the inner channel of the truck and are secured to the trucks by angle-clips J, riveted to the channel G and bolted to the trucks by bolts K, taking nuts k on the outer sides of the truck.

The wheels 19 of the truck occupy the space between the two channel members thereof and between the distanceblocks b 6 The axles of these wheels are journaled in bosses b 19 preferably made of cast-iron, carried on the outer sides of the truck-beams and havo ing on their inner faces projections b taking through openings inthe channel members. Bolts b extending through marginal flanges I), carried by the bosses, secure'them to the channel members.

On the driving side of the crane the axles of the wheels constitute a shaft L, extending across the frame and intermediately supported by brackets M, extending from the side of the bridge. This shaft is rotated by suitable means to move the crane, that shown being a system of gearing Z, leading to adriving-wheel Z, over which takes an operatingchain Z It will be observed that rivet connections are used in securing the angle-pieces to the bridge-beams and the bracing-channels and in securing these latter channels to the bridgebeams. This work may be done witha riveting-machine. Theconnections of the bridge and its channel-braces to the trucks, however, are provided by bolts, whereby the parts may be very conveniently assembled. In assembling the crane the channel members I) b are passed through the I-beams of the bridge, the distance-blocks put in place, and the various bolts applied. The wheels are then inserted and their journal-bosses bolted in place.

The advantages of this crane liein its great strength and rigidity and the cheapness with which it may be constructed, being composed of usual rolled forms, as I-beams and channel members, in the ease with which it may be separated and assembled, (thus providing for cheap transportation,) and in the saving of vertical head-room, which is efficiently secured byhaving the trucks pierce the bridge.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a traveling crane, the combination of a bridge with trucks supporting said bridge and passing continuously through the sides thereof, the material of said sides extending beneath the trucks, substantially as described.

2. In a traveling crane, a bridge having openings in its walls near the ends thereof,

combined with trucks supporting said bridge and passing continuously through such openings, said trucks being confined by the material of the bridge substantially embracing them, substantially as described.

3. In a traveling crane, the combination of a bridge having openings in its walls near the ends thereof said openings being entirely surrounded by the bridge, and trucks supporting said bridge and passing continuously through said openings, substantially as described.

4. In a traveling crane, a bridge consisting of a pair of parallel beams having alined openings near their ends, combined with a pair of trucks each consisting of a pair of parallel beams passing through said openings, the material of the bridge-beams extending between the truck-beams, substantially as described.

5. In a traveling crane, a bridge consisting of a pair of parallel I-beams having alined openings through the webs thereof a short distance from the ends and above the lower flanges, combined with a pair of trucks having beams passing continuously through the alined openings, substantially as described.

6. In a traveling crane, a bridge consisting of a pair of parallel I-beams having alined openings through the webs thereof a short distance from the ends and above the lower flanges, combined with a pair of trucks each consisting of two beams side by side passing continuously through the alined openings of the bridge and carrying supporting-wheels between them, substantially as described.
