This invention relates to improvements in truck bodies and is particularly adapted to garbage trucks employing the push out system of unloading.
The primary object of my invention is to provide a means of moving the plow, ejector plate or doze-r within the body of the truck without the load interfering with the operatin mechanism.
A further object of my invention is to provide a mechanism for moving the plow or ejector plate that will maintain the plane of the plow at right angles to the longitudinal center line of the body of the truck, and at the same time eliminating binding of the plow or ejector plate within the body of the truck in its operation.
In the operation of push-out type bodies as commonly used in garbage work; difficulty has been experienced in moving the plow or ejector plate throughout the length of the body due to the fact that the materials in the load came in contact with the mechanism for moving the plow, jamming the same in its operation.
With my new and improved operating mechanism, this jamming effect has been reduced to a minimum by enclosing the operatin mechanism within channels running longitudinal of the body; and by mounting the plow to the operating mechanism, at least four points, maintaining the plow in a fixed position relative to the body in its operation.
These and other incidental objects will be apparent in the drawings, specification and claims.
Referring to the drawings:
Figure 1 is a side view of a push-out type garbage truck body having my new and improved plow or ejector plate operating mechanism installed thereon.
Figure 2 is an enlarged longitudinal sectional view of the body, taken on line 22 of Figure 5, part of the body being broken away.
Figure 3 is an enlarged detail sectional view of one of the gear boxes associated with the operating mechanism.

Figure 8 is an enlarged detail fragmentary sectional plan view taken online 8-8 of Figure 2, illustrating the method of connecting the driving mechanismtothe plow.
Figure 9 is a fragmentary perspective detail of the connection between the drive chain and the deter unit.
Figure 10 is a fragmentary sectional detail of the chain housing associatedwith the bod-y of the truck.
Referring more specifically to the drawings:
I illustrate invention in connection with apush-out type body l, mounted upon the usual In garbage trucks these bodies are usually cut out at 3, which may be closed by a sliding panel 4 the object of the cut-out is.
for the convenience of loading the trucks, and the tail gate 5 is usually of the swinging door type. A plow, ejector plate or dozer 6 is mounted transversely of the body and ismoved there along by a power means.
My invention consists of operating mechanism such as endless chains 1 or equivalent actuating meansrunnin'g longitudinally of the body within? upper and lower channeled casings or housings Slocated on the outside of the bodyside walls 9, and aligned upper and lower longitudinal channeled casings It! located on the inner sides of the side walls of the body. These chains are trained about driving sprockets ii at the forward end of the body, said driving sprockets are keyed to the vertical shafts E2, the said shafts being journalled within the combined housings 8 and I8 extending beyond the body of the truck at IS.
The vertical shafts I2 are driven in unison by the cross shaft M by way of gear reduction units shown as consisting of bevel gears 55 and it P located within the housing 16A. The cross shaft l4 in turn is driven by the gear reduction unit I613. The gear reduction unit is driven by the power take off shaft 11 through the chain E8 of the truck. The power take off arrangement being of well known construction, having a control lever for throwing it in or out of gear not here shown.
The chains 7 are trained about idler sprockets i9 located at the rear end of the body, referring to Figure 4. The plow or ejector plate 5 is secured to the chains by way of the brackets 26 and 2!, best illustrated in Figures 4, 7 and 3, .the said brackets being connected to the chain at 22 by way of special links 22A associated with the chain. Due to the fact that there are four chains, two on each side of the body, the plow or ejector plate is held in a definite movable position within the body and prevented from binding with the body.
The lower portion of the plow or ejector plate is sloped as at 23 and as the same is pushed rearwardly against the load, the sloped portion is held down by the load tending to maintain the plow in a vertical position in its movement. This sloping portion also eliminates having to move the plow the entire length'of the body, thereby allowing room for the sprockets I9 to operate within the ends 19A forming part of the housings 8 and 56, without being contacted with the brackets 29 and 21 of the plow.
In the operation of my new and improved pusher-type body, the operator of the truck operates the power take off shaft in the desired direction for either pushing the load out or bringing the plow or ejector plate back to the front of the body. Due to the fact that all of the chains are timed to the vertical shafts l2, and these shafts being in turn driven in unison by the gear reduction units or gears [Ea-i5 in the housings or boxes IBA, the plow will be moved so that its plane will be at right angles to the center line of the body at all times.
The inner channeled casings or housings l8 have openings or slots 29 running longitudinal thereof at the bottom, permitting the brackets 29 and 21 to move therealong, and due to the fact that the slots 24 are very narrow and at the bottom of inner channeled casings 9, foreign matter is prevented from entering the same and interfering with the operation of the chains 1. This feature is the outstanding point of my invention, and the fact that these housings require a minimum of space for their operation. Further the housings 8 and I9 provide re-enforcement for the body adding very little to the cost in the production of the body.
Although certain specific embodiments of the invention have been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.
What I claim is:
1. A truck body comprising side members, a
bottom, and a front member, each side member having upper and lower inner and outer longitudinal channels, the bottom of each inner channel having a longitudinal slot, vertical shafts at the front and rear ends of the channels, sprocket wheels on the shafts, endless sprocket chains trained around the sprocket wheels and operating in the upper and lower inner and outer channels, means for simultaneously operating the shafts, a plow fitting between the side members of and on the bottom of the body, said plow having upper and lower recesses on the sides opposite the inner channels to freely pass over said inner channels when the plow is moved back and forth in the body, lugs extending upwardly from the bottom walls of the recesses and extending through the longitudinal slots in the channels, said lugs having outwardly extending projections, each said projection being pivoted to a link of the chain operating in the inner channels.
2. A truck body, comprising side members, a bottom, and a front member, each side member having upper and lower inner and outer longitudinal channeled casings, the bottom of each inner channeled casing having a longitudinal slot, an ejector plate fitting between the side members of and on the bottom of the body, said ejector plate having upper and lower recesses on the sides opposite the inner channeled casings to freely pass over said inner channeled casings when the plow is moved back and forth in the body, a lug extending upwardly from the bottom walls of the recesses and extending through the longitudinal slots in the inner channeled casings, said lugs having outwardly extending projections, and power driven operating means in the channeled casings associated with the outwardly extended projections to move the ejector plate back and forth in the body.
