Claim 4

A side loading refuse truck according to claim 1 in which there is a lost-motion connection between the ram and the shield and said shield is engaged by said lost-motion connection and pulled rearwardly by said ram only when said ram moves rearwardly beyond the intermediate position thereof.

Claim 5

A side loading refuse truck according to claim 1 in which the compartment, the receiving body, the hydraulic mechanism, including the ram, the shield and the guide are a unitary structure and are adapted for mounting as such on a truck chassis.

Claim 6

Claim 7

A side loading refuse truck body having a. a loading compartment, b. a larger refuse receiving chamber adjacent the compartment and rearwardly thereof, c. a floor for the compartment and a floor for the chamber that lie in the same horizontal plane, d. a partition between said compartment and said chamber defining an opening between the compartment and the chamber, e. a low profile ram movable along said floors for pushing refuse from the bottom of the loading compartment through such opening and into said receiving chamber, f. horizontal guides for said ram extending from forward of said loading compartment to the rear of said chamber for guiding said ram along said floor from a front position forward of said loading compartment to an intermediate position with its rear face closing such opening and to a rear position at the rear of said chamber for ejecting refuse therefrom, g. a shield comprising a plurality of articulated members and having a length sufficient to extend from the front of said compartment to the front of said ram when said ram is in its rear position, h. means connecting said ram to said shield for movement therewith when said ram is moved to its rear position, i. vertically extending shield guides at the front of said compartment for receiving said shield when said ram is at its front position, and j. hydraulic cylinder means connected between the front end of said body and said ram for reciprocating said ram through the bottom of said loading compartment and to and from the rear of said receiving chamber.

Claim 8

A refuse truck according to claim 5 and horizontal shield guides extending rearwardly from the loading compartment to the rear of the travel of the shield in the receiving chamber.

Claim 9

A refuse truck according to claim 5 and arcuate guide sections connecting the lower end of the horizontal shield guides to the vertically extending shield guides.

Claim 10

A refuse truck according to claim 5 in which the articulated shield is pivotally connected to the front upper edge of the ram and movable with said ram.

Claim 11

A refuse truck according to claim 5 in which the articulated shield comprises a horizontal sliding cover and there is a lost-motion connection between the ram and said cover, whereby said cover and said shield are engaged by said ram for rearward movement therewith only when said ram is moved rearwardly beyond the intermediate position thereof.

Claim 12

A refuse loading and transporting truck having a loading compartment at one end thereof, a larger refuse storage body adjacent such loading compartment, a floor of said loading compartment and a floor of said body lying in substantially the same plane, a partition extending downwardly to a level spaced above said floors and defining an opening from said loading compartment into said body and a ram having a closed rear face and a closed top that is mounted for reciprocatory movement across the bottom of said loading compartment for pushing refuse from said loading compartment through said opening, that is characterized by a. horizontal guides for said ram extending from forward of said loading compartment to the rear of said storage body for guiding said ram along said floors from a front position with the rear face of said ram closing said opening and to a rear position at the rear of said storage body for ejecting refuse therefrom, b. hydraulic mechanism for alternatively reciprocating said ram through said storage compartment and into, out of and through said storage body, c. a multi-part horizontal shield extending the width of said floors and including said top on said ram and having a total length sufficient to extend from the front of said compartment to the rear face of said ram when said ram is in its rear position to assist the ram in the unloading of refuse from said storage body, d. means coupling said shield parts to said ram for movement with said ram when said ram moves at least rearwardly of said partition, and e. shield guides extending from forward of said loading compartment to the rear of said storage body for storing said shield parts other than the top of said ram when said ram is at its front position and for guiding said other shield parts as said ram is moved between its position closing said opening in said partition and its rear position.

Claim 13

A refuse loading and transporting truck having a loading compartment at one end thereof, a larger refuse storage body adjacent such loading compartment, a floor of said loading compartment and a floor of said body lying in substantially the same plane, a partition extending downwardly to a level spaced above said floors and defining an opening from said loading compartment into said body and a ram having a closed rear face and a closed top that is mounted for reciprocatory movement across the bottom of said loading compartment for pushing refuse from said loading compartment through said opening, that is characterized by a. horizontal guides for said ram extending from forward of said loading compartment to the rear of said storage body for guiding said ram along said floors from a front position with the rear face of said ram closing said opening and to a rear position at the rear of said storage body for ejecting refuse therefrom, b. hydraulic mechanism for alternatively reciprocating said ram through said storage compartment and into, out of and through said storage body, c. a multi-part horizontal shield extending the width of said floors and including said top on said ram and having a total length sufficient to extend from the front of said compartment to the rear face of said ram when said ram is in its rear position to assist the ram in the unloading of refuse from said storage body, d. means coupling said shield parts to said ram for movement with said ram when said ram moves at least rearwardly of said partition, and e. shield guides extending from forward of said loading compartment to the rear of said storage body for storing said shield parts other than the top of said ram when said ram is at its front position and for guiding said other shield parts as said ram is moved between its position closing said opening in said partition and its rear position.
