TRUCK-MOUNTING FOR TRAVELING- CRANES.

To all whom it may concern.'V

Be it known that I, HOMER W. ISRAEL, of Vaulresha, Wisconsin, have invented a Truck-Mounting for Traveling Cranes, of which the following is a specification.

This invention has for its object to improve the mounting` of crane-trucks, first by providing a novel and superior form of truck-girder, and secondly by providing an improved rest for the journal-boxes carrying the truck-wheels.

The nature of my invention is best understood by a consideration of the following description of a concrete form thereof, taken in connection with the accompanying drawings, wherein,

Figure l is a plan view of a crane-truck embodying my invention; Fig. 2 is a side elevation thereof, Fig. 3 is an end elevation of the same, Fig. 4 is a transverse section through the truck-beam, and Fig. 5 is a vertical section through the journal and journal-box showing the means for rigidly supporting the journal against lateral movement.

In the drawings every reference let-ter and numeral refers always to the same part.

In the drawings the truck-beam is designated A and is of special form, being a box-girder made up of two horizontal channels a', a2 and two web-plates a3, flanking them at either side and secured thereto. This girder A is supported upon flangewheels B at its ends which ordinarily roll upon the rail C, as is usual with traveling cranes; and it supportsthe crane-girders D, which may be made up in any preferred form, these not being a part of my invention. The girder A is reinforced at its ends by additional web-plates a4 laid against the web-plates a3 and riveted thereto, and all these web-plates are cut away rectangularly at the ends to admit the journal-boxes or bearing-eases E which partially inclose the journals b of the wheels B, and also the bearing-blocks or brasses F which rest upon Said journals. The wheels are set in the vertical longitudinal axis of the girder A, and one journal thereof is shown as prolonged to receive the gear-wheel Gr by which said wheel is propelled through a shaft H carrying a pinion la. meshing with said gear Gr, This arrangement of elements for propelling the truck is not a part of this inven- Speeieation of Letters Patent.

tion and may be altered or substituted without interfering therewith. As further supports for the brasses F upon which the girder A rests, there are secured to the sides of the webs a3, a4 horizontal angles a5 and vertical angles a, being flush with the edge of the rectangular cut in said webs, and a transverse channel a7 is set vertical within the beam connecting the webs thereof.

The brass F does not rest directly upon the angles a or web-plates but an angularpiece I is interposed, and this piece has a jog or projection i near the end of its horizontal limb. The bearingcase E is so shaped that the end of its upper horizontal face ts neatly within said jog or projection, and it is secured in place by means of two bolts e', e2 passing through the angular members I and flanges a5, a, respectively. The brass F is confined between the upper portion ew of the bearing case and the upright limb of the piece I, so that horizontal movement thereof in a longitudinal direction is absolutely prevented; and the bolts e, e2 serve to iirmly and rigidly hold the bearing-case in its proper position so that lateral movement is impossible. This jog z" is an important element of my invention, since I have found that unless such jog or its equivalent is provided the bearing-case and consequently the brass will work loose and become shifted longitudinally for the reason that the hole e3 in the portion 01 through which the bolt e passes is necessarily cast somewhat too large for the bolt and there is therefore nothing but the friction between the brass to prevent longitudinal displacement unless such jog i is provided.

The bearing-case E is provided with a lid e* at its outer end pivoted at e5, through which the lubrication e may be poured and the usual waste-pad e7 is inserted or removed. To prevent the oil or other lubricant from running out of the case through the hole e8 in the bottom of the case E which admits the bolt e', a lug e is formed around said hole to a point slightly above the level of the lubricant, that is on a level with the bottom of the journal.

The formation of the girder A as shown is superior to common girder-forms wherein vertical I-beams or channels are secured to horizontal web-plates. This arises from the fact that in order to make the girder of the most economical depth, thinner .webs are required in the vertical members than can be obtained in the market-sizes, that is to say without special rolling. Of course with this construction light channels can be used and the web-plates can be made with any desired thickness.

I wish it understood thatmy invention is capable Of modification within the reasonable scope of my claims and that I consider all such modifications and variations to be constructed within the spirit o-f my invention.

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