6 Claims. (cries-4'95) i This invention relates to improvementsin sixwheel trucks andmore particularly to improved :meansforlubricating wear parts.
Theprimary objectof the invention is to provide novel means for lubricating all wearing parts at the connections between the side frame and equalizer members in order to materially reduce the frictionand wear between adjacent parts.
other objects in view whichwillappear as the description proceeds, the invention consists in the novel featureshereinafter described in detail inconnection with the accompanying drawings and more particularly pointed out in theappend- In the drawingszf t e i Fig. 1 is afsideelevation ofthe medial portion of a six-wheel truckprovided with our improvements. W V
Fig. 2 is a transverse vertical sectional view of a portion of the same taken on the line 2-2 of Fig. 3. f
Fig, 3 is a side elevation partly in longitudinal vertical section" of a portion of the truck; the section being taken on the line 33 of Fig. 2.-
Referring to the drawings, 4 designates one of the wheelsof a sixewheel truck including equalizer members, one of which is shown in Fig. 1 and designated 5. t
As best shown in Figs. 2 and 3, each end of. the equalizer member is provided with a pair of upstanding apertured ears 8 having Wear plates 1 welded to their inner surfaces. Another wear plate 8 is secured to an arc-shaped portion 9 which is arranged between and is located at the lower ends of the ears. The plate 9 and. the ears form a cradle for a supporting block III which has a curved bottom surface to slide on the plate 8.
The inner ends of the side frame members ll rest on the blocks l0 and are positioned between the ears 6, and they are loosely and turnably secured or movably connected to the ears by bolts I la. Wear plates l2 are welded to opposite sides of the ends of the side frame members and bear against the plates 1.
The operation of our truck requires clearance between the bolts Ila and the holes in the side frames ll because the. side frames must slide slightly on top of the blocks l0. Consequently, clearance is provided about the bolts (see Figs. 2 and 3) to permit movement of the inner ends of the side frames on the blocks l0, and movement of the blockson the plates 8 without the side frames contacting the bolts Ila. It will With the foregoingobject outlined and with therefore be apparent that the bolts function I more as retaining means than as pivotal connections for the'side frames and equalizers.
Lubricant pockets or reservoirs 93 are formed integral with the inner ends of the side frame 5 members, and ports [4 lead from the bottoms of the pockets to the bolts. Each pocket is preferably provided with an open upper end. When waste saturated .with lubricating 'oil i inserted in the pockets, such oil will pass fromv 10 the pocketsthi ough the ducts I4 to the bolts, then along them horizontally inboth directions to thewearing surfacesbetween the plates land l2. The oil passes between these plates by'gravity to the bottom of the connections where, it 15 lubricates the "wearing surface of the blocks II and plates 8. In this manner all wear parts at the connections are thoroughly lubricated, thereby. reducing the friction and wear between adjacent p'arts, I While we have disclosed what we now consider to be a'preferred embodiment of the invention in such manner that the same may be readily understood by those skilled in the art, we are aware that changes may be made in the details disclesed without" departing from the spirit of theinvention as expressed in the claims.
What we claim and desire to secure by Letters Patent is:
