SPECIFICATION forming part of Letters Patent N 0. 718,676, dated January 20, 1903.
Application filed June 24-, 1902. Serial No. 1131037.
To aZZ whom it may concern:
Be it known thatI, CLARENCE L. TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Overhead Traveling Cranes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in overhead traveling cranes; and it consists, I primarily, in mounting the bridge and trolley on independent trucks, the connections be tween the trucks and parts thereon being such that the parts supported on the trucks can be jacked up and the latter removed without threading any shafts through holes, thus not only materially lessening work in assembling the parts, but also greatly simplifying the operations and reducing the cost of the removal of any of the parts for the purpose of replacement or repair.
My invention further consists in the parts and combinations of parts and in the details of construction, as will be. more fully described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in elevation of my improved crane. Fig. 2 is a plan view of the trolley on an enlarged scale. Fig. 3 is a view in end elevation of the trolley, showing a section of the bridge and the bridge-supporting track. Fig. 4 is a sectional view on the line 00 w of Fig. 3, showing also a portion of the bridge in section. Fig. 5 is a view on the line to w of Fig. 3; and Fig. 6 is a View in section on the line 11 y of'Fig. 8, Figs. 4, 5, and 6 being'on a larger scale than Fig. 3.
1 represents a traveling bridge provided with end trucks 2, the flanged Wheels 3 of which travel on the elevated trackway 4. This trackway is usually located adjacent to the side walls of the building or sides of the bay, so as to permit it and the trolley thereon to take in the entire floor-space below.
The bridge 1 is constructed in any suitable manner,but preferably of parallel girders con- (No model.)
nected at their ends by end frames 6, and is mounted at each end on a pair of trucks 2. 5o vEach truck 2 consists of a frame mounted on two flanged wheels 3, the latter traveling on the elevated tracks 4, as above explained.
Each end frame 6 is provided near its ends with the steel or other suitable metallic blocks 5 5 7, each of which is provided on its lower face with a semicylindrical bearing '8 for the reception of the cylindrical bearing 9. The blocks 7 instead of being secured in or to the end frame may be secured within the girders 6o constituting the bridge 1, at the free ends of the latter, and in either event they form the seat or rests through which the weight of. the bridge is transmitted to the truck. In the present instance each truck is shown as composed of a frame or body and two flanged Wheels arranged tandem. It is evident, however, that more than two wheels may be employed, and they may be arranged in pairs, as these details are not essential to my invention. Each truck is provided on its upper surface, preferably midway its ends, with the semicylindrical recess 10 for the reception of the bearing 9. The semicylindrical recess in each block 7 when combined with the corresponding recess in its truck forms a cylindrical opening in which the cylindrical block 9 rests and on which its truck and corresponding end of the bridge rocks or oscillates. This, cylindrical block not only forms a loose joint '80 or connection between the parts, but it also locks them together, the weight of the bridge and parts thereon being sufficient to prevent the possibility of a separation of the parts, and in order to prevent any movement of the hearing 9 within its seat I provide the cylindrical hearing or block 9 with flanged ends 11, which latter overlap the block 7 and truck 2 and lock the bearing in place. The track or flanged wheels 3 are located approximately in the plane of the longitudinal center of the trucks 2, and as the cylindrical hearings or blocks are of slightly-greater length than the width of the trucks and overlap both sides of the latter it will be seen that the tendency of the trucks to tilt is entirely overcome.
The bridge is supported at its four corners on these trucks, and as the connections between the trucks and bridge are pivotal connections it will be seen that the trucks can pass over joints between the rails or other uneven surfaces without straining or injuring the bridge.
The trolley 12 is carried by the bridge and is adapted to travel lengthwise the latter. This trolley, like others employed on overhead traveling cranes, consists of two side frames 13, connected by the block or sheave carrying girders 14 and support the hoisting drum or drums and the necessary motors and gearing for imparting cross-travel to the trolley and rotary motion to the hoisting drum or drums. The trolley thus constructed is mounted at its four corners on the trucks 15, which are constructed substantially like those which carry the bridge-that is to say, each comprises a truck-frame 16 and two track or flanged wheels 17, the latter resting on the rails 18, which are located on and lengthwise the bridge-girders. Each truck-frame 16 is provided on its upper surface, in a plane passing midway between the track-wheels l7,with a semicylindrical bearing 19, the two semicylindrical bearings of the trucks at one end of the trolley forming bearings for the shaft 20, carrying the main hoisting-drum 21,while the two bearings 19 in the truck-frames at the opposite end of the trolley form bearings for the shaft 22 of the auxiliary hoisting-drum 23. These shafts simply rest in the semicylindrical bearings of the truck-frames 16 and form supports on which the ends of the trolley 12 rest, the sides of said trolley 12 having semicylindrical recesses or seats conforming to the contour of the shafts. These shafts, as clearly shown in the drawings, are provided with collars 24 and nuts 25, which prevent anylongitudinal movementin their bearings and which also operate to prevent any lateral or sidewise movement of the trucks or trolley-frame on the shafts. The drums are preferably mounted to rotate on the shafts, and each is driven by an independent motor through suitable gearing, which is shown,but which forms no part of the present invention.
With the construction described it will be seen that the trolley and bridge are each pivotally mounted on a series of independent trucks, which not only permits the bridge and trolley to pass over inequalities in the tracks without straining the parts, but which also considerably simplifies the present construction and greatly reduces the cost of assembling the bridge on the trolley and the trolley on the bridge. In assembling the trolley the hoisting-drums being independent of the trolley may be first assembled on their respective shafts and then raised into position and properly placed without threading the shafts through any holes.
It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an overhead traveling crane, the combination with a series of independent trucks I supporting one end of a bridge, each truck having a transverse semicylindrical seat on its upper face, of a bridge having a bearing extending in the direction of the length of the bridge, for each cylindrical seat of the several trucks, and supported at one end on said trucks.
2. In an overhead traveling crane, the combination with a bridge, and a series of end trucks supporting each end of the bridge, of a cylindrical bearing, and a block resting on the upper face of each truck and forming a supporting-seat for the bridge, each bearing or block extending in a direction at right angles to the length of the trucks.
3. In an overhead traveling crane, the combination with end trucks and a bridge, each truck having a semicylindrical recess in its upper face and the bridge having a corresponding series of recesses in its lower face near its ends, of a cylindrical hearing or block located within the recess in each truck and forming a curved seat for its corresponding recess in the bridge.
4. In an overhead traveling crane, the combination with a bridge and a series of independent trucks, of a cylindrical bearing-block for each truck, each block resting in a recess in its truck and engaging a correspondingshaped recess in the bridge, and provided with enlarged or flanged ends.
