Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
In a chassis construction, a frame, fixed bolsters at the front and at the rear of the frame, vertically extending securing means for a container at the ends of the rear bolster, housing means located at the ends of the front bolster, each having a rearwardly disposed plate containing an upper and lower aperture, horizontally extending pin means projectable through either the upper or lower aperture to extend rearwardly of said plate, said frame having side rails which terminate short of the front end thereof, a plate secured to the front end of the rails to which the front bolster is attached, and supporting means on said plate disposed parallel to said side rails in position for engagement by the front bottom portion of a container of the channel type.
Claim 2
Dependent Claim
130 words
In a chassis construction, a frame, fixed bolsters at the front and at the rear of the frame, vertically extending securing means for a container at the ends of the rear bolster, housing means located at the ends of the front bolster, each having a rearwardly disposed plate containing an upper and lower aperture, horizontally extending pin means projectable through either the upper or lower aperture to extend rearwardly of said plate, said frame having side rails which terminate short of the front end thereof, a plate secured to the front end of the rails to which the front bolster is attached, and supporting means on said plate disposed parallel to said side rails in position for engagement by the front bottom portion of a container of the channel type.
Claim 3
Dependent Claim
35 words
In a chassis construction as recited in claim 1, wherein the supporting members are inverted channel elements one being disposed on the center of the plate and the outer one being aligned with the rails.
Claim 4
Dependent Claim
23 words
In a chassis construction as recited in claim 2, wherein fluid conduits, electrical conductors or both extend through one of said channel elements.
Claim 5
Dependent Claim
58 words
In a chassis construction as recited in claim 1, wherein structural members are pivoted to said rails for movement from a position on the top thereof to a position at the side thereof, the top of said structural members sloping rearwardly for supporting intermediate crossmembers on a container with the crossmembers forwardly thereof disposed above and supporting members.
Claim 6
Dependent Claim
43 words
In a chassis construction as recited in claim 4, wherein the slope of the structural members substantially falls on the slope of the container when its front crossmembers are located above the supporting members and its rear end rests on the rear bolster.
Claim 7
Dependent Claim
46 words
In a chassis construction as recited in claim 1, wherein said housing means having a vertical passageway therein in which the horizontally extending pin means is vertically shiftable from a bottom position aligned with the lower aperture to an upward position aligned with said upper aperture.
Claim 8
Dependent Claim
69 words
In a chassis construction as recited in claim 6, wherein a nut is mounted for rotation in said housing and for vertical movement adjacent to said passageway, said pin having a section of thread thereon engaged by the thread of the nut and having flat sides which engage the sides of the passageway and prevent it from turning when the nut is rotated for advancing or retracting the pin.
Claim 9
Dependent Claim
61 words
In a chassis construction as recited in claim 7, wherein a pivoted shelf is mounted within the housing for movement to a horizontal supporting position, a pin with a tapered head mounted on said shelf for locating the front bottom corners of a container when supported thereby in position to be tied down by said pin when in said upper aperture.
Claim 10
Dependent Claim
43 words
In a chassis construction as recited in claim 8, wherein said shelf is hinged to a vertical position recessed within the housing, and a latch on said housing actuated by the tapered head of the pin for locking the shelf in vertical position.
