Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
A sheet retainer for use with conveyors for delivering paper to the register stops of a printing press including an elongated support and clamping means at the ends of said support for fixing said support above a paper feeding conveyor, a ball support block having plural, spaced ball cavities therein, said cavities being formed through said support block from the upper surface thereof to the lower surface thereof, a retainer ball in each cavity, each cavity terminating in an opening through the bottom of said ball support block and of smaller diameter than the ball therein, second clamping means for supporting said support block from said elongated support and for adjustably positioning said ball support block along the length of said elongated support, said second clamping means including a pair of clamping members for embracing said elongated support, and resilient means for causing a resilient bias of said clamping members toward one another and for yieldingly holding said ball support block at a selected distance from said elongated support.
Claim 2
Dependent Claim
169 words
A sheet retainer for use with conveyors for delivering paper to the register stops of a printing press including an elongated support and clamping means at the ends of said support for fixing said support above a paper feeding conveyor, a ball support block having plural, spaced ball cavities therein, said cavities being formed through said support block from the upper surface thereof to the lower surface thereof, a retainer ball in each cavity, each cavity terminating in an opening through the bottom of said ball support block and of smaller diameter than the ball therein, second clamping means for supporting said support block from said elongated support and for adjustably positioning said ball support block along the length of said elongated support, said second clamping means including a pair of clamping members for embracing said elongated support, and resilient means for causing a resilient bias of said clamping members toward one another and for yieldingly holding said ball support block at a selected distance from said elongated support.
Claim 3
Dependent Claim
23 words
The structure of claim 1 wherein plural ball support blocks of the type recited are positioned along the length of said elongated support.
Claim 4
Dependent Claim
34 words
The structure of claim 1 wherein said ball support block includes a retaining plate swivelly mounted on the upper surface of said ball support block and overlying at least a portion of each cavity.
Claim 5
Dependent Claim
33 words
The structure of claim 1 wherein said resilient means includes a spring extending between one clamping member and said ball support block, said ball support block being coupled to the other clamping member.
Claim 6
Dependent Claim
105 words
The structure of claim 4 wherein said ball support block is coupled to said other clamping member by a post upstanding from said ball support block, said one clamping member being in the form of a clamping block, said clamping block slidably receiving said post, said other clamping member being in screw-threaded relation to said post to provide adjustment of said other clamping member toward and away from said ball support block, said spring being effective to yieldingly hold said ball support block at a fixed distance from said clamping block as determined by the position of said other clamping member relative to said post.
Claim 7
Dependent Claim
27 words
The structure of claim 5 wherein said elongated support is in the form of plural parallel rails and said clamping block is grooved to receive said rails.
Claim 8
Dependent Claim
70 words
The structure of claim 1 wherein said first named clamping means includes a clamping block at each end of said support, each clamping block having a downwardly and outwardly inclined outer side surface whereby said support may be fixed to parallel support rods by positioning said support on said rods with said inclined surfaces in engagement with the sides of said rods at points below the centers of said rods.
