LUBRICATING DEVICE FOR OVERHEAD TRAVELING CRANES.

SPECIFICATION formingpart of Letters Patent No". 624,994, dated May 16, 1399.

Application filed March 4, 1898.

To all whom it may concern:

Be it known that I, CLARENCE LANDFEAR TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new 5 and useful Improvements in Lubricating Devices for 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 lubricating devices for overhead traveling cranes. p

In a large majority of the overhead travel- 5 ing cranes now in use the end carriages of the bridge run in close proximity to the walls or girders supporting the runways, and as the axlescarrying the track-wheels are supported in bearings on both sides of the wheels there is no room for self-oiling boxes opening outwardly between the wall or girder and the ends of the axles. Hence these axles have been oiled through oil-holes formed in the tops of the bearings, and as these holes are necessarily small they hold but little oil, and as they are above the axles the oil therein is soon used up. This necessitates frequent oiling of the axles and expensive delays; and the obj eet of myinvention is to provide overhead cranes with oil-boxes of ample capacity having lids or openings arranged parallel with the axle, so as to renderthem easily accessible and at the same time not occupy valuable space between the ends of the axle and the walls or girders.

With these ends in view my invention consists in the parts and combinations of parts, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation of one end of a traveling crane, showing my improved oil-boxes thereon. through one axle and lengthwise of the box. Fig. 3 is a view of a modification; and Fig. 4 is a view in section of one end carriage of Fig. 1, showing two bearings andoil-boxes and the wheel between the bearings.

In Fig. 1, A represents a section of a traveling bridge. This bridge comprises longitudinal'girdersB and end carriages C, mount- Fig. 2 is a view in transverse section Serial No. 672,580. (No model.)

ed on wheels, which latter travel on runways D, only one of which,'however, is shown.

- In a large majority of cranes the runways are located well up to the walls E of the build- 5 5 ing, so as to enable the trolley to cover the entire floor-space. The wheels F of the-end carriages C run on the rails of the runways D, and as each wheel is mounted on an independent axle supported in bearings on oppo- 66 site sides of the wheel it follows that there is no room between the outer ends of the axles and walls for oil-boxes or for outwardly-open ing lids of oil-boxes. Hence heretofore these axles have been lubricated by the introduction of small quantities of oil introduced at comparatively short intervals through holes in the top of the bearings, the holes leading down to the axles.

My invention is designed to furnish self- 70 oiling bearings, and it comprises boxes G, removably secured to the under side of the end carriages, eachbox carrying a supply of oil,

in which the axle moves, or which can be fed to the axle by cotton-waste or any. other approved means. The end carriages C aresupported on these axles, and the boxes G, one for each end of the axle, are provided with semicircular recesses a in the sides for the reception of the lower halves of the axles. These boxes are as wide as the projecting ends of the axles or as wide as the axle-bearings, so as not to project beyond the axles, and are removably secured at one end to the under sides of the end carriages, so as to cover'and embrace the exposed portions or lower halves of the axle. Each box is closed at one end, so as to make a close fit with the end carriage, and is provided with a slotted flange H, each flange having'preferablya pluo rality of slots, and is secured in place by the bolts H, (only one of which is shown,) passing through the slots and into the end carriages. The bottom of the box is preferably curved, and the outer end of each is inclined 5 upwardly and provided with a hinged lid or cover I, mounted in bearings I on the top of the box. From this it will be seen that the lid or cover rests parallel with the axle, and

as it is wholly within the plane of the outer end of the axle it does not take up any space that could otherwise be used by the bridge,

and consequently does not rob the crane of any cross-travel.

In Fig. 3 I have shown a bridge constructed to carry two trolleys and have shown a trolley resting on rails carried by the lower flanges of the bridge-girders. With this construction it will be seen that the track-wheels run in close proximity to the inner faces of the bridge-girders, thus rendering it impossible to interpose oil-boxes between the girders and axles, and it is also impossible to employ axlebearings on the outside of the wheels. To lubricate these axles, I employ boxes G, identical in all respects with those shown in Figs. 1 and 2, and locate them under the axle and axle-bearings adjacent to the inner faces of the wheels. With this arrangement the oilboxes are accessible from the ends of the trolley and the oil can be supplied thereto in a quantity sufficient to last for days.

If preferred, I can provide the box with a cross-bar or abutment J, designed to hold the waste in contact with the axle and prevent its creeping toward the opening.

It is evident that changes in the construction of the box and the manner of securingit to the end carriage might be resorted to without departing from the spirit and scope of my invention. Hence I would have it understood that I do not confine myself to the details herein shown and-described, but consider myself at liberty to make such changes as may come within my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the end carriages of an overhead traveling crane, a plurality of wheels supporting said end carriage and an axle for each wheel, each axle resting in bearings on opposite sides of the wheels, of an oilbox for the outer end of each axle, the said oil-b0x resting wholly under the axle-bearing and axle, substantially as set forth.

2. The combination with end carriages of an overhead traveling crane, a plurality of wheels supporting said end carriage and an axle for each wheel, each axle resting in bearings on opposite sides of the wheels, of an oilbox for the outer end of each axle, each oilbox being removably secured in position underits respective axle, and each provided with a lid located parallel to the axle, substantially as set forth.

3. The combination with a wheeled trolley, of an elongated oil-box open at its top and one end, and provided with semicircular recesses in its sides to receive the axle, the bottom of said box being inclined downwardly from the open end to a point under the semicircular recesses thus forming an oil-well immediately below the axle, and a cover for the open end of the box, the closed end of the box having an integral flange for reinovably securing the box in position, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CLARENCE LANDFEAR TAYLOR.
