Abstract
Abstract A jogger for aligning stacked sheets of paper or the like comprising a tilted table and a pair of jogger arms pivotally mounted to the table. The jogger arms carry paddle portions which extend above the tabletop along two adjacent sides of the table. Followers on each arm are operatively engaged by a multilobed cam which causes the arms and associated paddles to pivot in synchronism and bring into alignment sheets stacked on the tabletop. A prop may be provided on the tabletop to facilitate the alignment of cross-stacked sheets.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A jogger for aligning stacked sheets of paper or the like comprising A. an inclined table angled substantially toward one corner thereof, B. a pair of elongate paddles disposed along and in spaced relationship with adjacent edges of said table proximate said one corner and extending above the upper surface of said table, C. means mounting said paddles for pivotal movement with respect to said adjacent edges of said table such that opposite ends of said paddles contact said adjacent edges of said table at the end of said pivotal movement of said paddles, and D. driving means causing relative, alternating clockwise and counterclockwise pivotal movement between said paddles and said table whereby misaligned sheets stacked on said table are agitated by contact with said paddles and brought into stacked alignment.
Claim 2
Dependent Claim
131 words
A jogger for aligning stacked sheets of paper or the like comprising A. an inclined table angled substantially toward one corner thereof, B. a pair of elongate paddles disposed along and in spaced relationship with adjacent edges of said table proximate said one corner and extending above the upper surface of said table, C. means mounting said paddles for pivotal movement with respect to said adjacent edges of said table such that opposite ends of said paddles contact said adjacent edges of said table at the end of said pivotal movement of said paddles, and D. driving means causing relative, alternating clockwise and counterclockwise pivotal movement between said paddles and said table whereby misaligned sheets stacked on said table are agitated by contact with said paddles and brought into stacked alignment.
Claim 3
Dependent Claim
36 words
A jogger as defined in claim 7, including prop means mounted on said table for elevating the overhanging extremities of cross-stacked sheets in a manner to relieve pinching and facilitate the alignment thereof by said paddles.
Claim 4
Dependent Claim
51 words
A jogger as defined in claim 2 wherein said prop means comprises a bent spring wire secured to said tabletop at one end and sloping downwardly toward said paddles, the other end of said spring wire being freely engaged in an opening in said tabletop to provide a resilient mounting therefor.
Claim 5
Dependent Claim
22 words
A jogger as defined in claim 1 wherein said paddles are pivotally mounted at effective pivot points located at substantially their midlengths.
Claim 6
Dependent Claim
63 words
A jogger as defined in claim 1 wherein said paddles are supported by separate arms pivotally mounted to said table, said arms carrying cam followers, said driving means comprising a continuously rotating multilobed cam, the lobes of which are in operative engagement with said cam followers, whereby, upon rotation of said cam, said jogger arms are pivoted in synchronism to pivot said paddles.
Claim 7
Dependent Claim
41 words
The jogger defined in claim 5 wherein the positioning of said arms and the configuration of said cam are such that when one cam follower is riding a lobe peak, the other cam follower is riding in a depression between lobes.
Claim 8
Dependent Claim
26 words
A jogger as defined in claim 5 including a spring connecting said jogger arms and urging said cam followers to follow the contour of said cam.
Claim 9
Dependent Claim
16 words
A jogger as defined in claim 5 wherein the lobes of said cam are buttress shaped.
Claim 10
Dependent Claim
20 words
A jogger as defined in claim 8 wherein said cam carries 10 buttress-shaped lobes equally spaced around the periphery thereof.
Claim 11
Dependent Claim
45 words
A jogger as defined in claim 1 wherein said means mounting said paddles comprises an arm connected to each paddle at substantially the midlength thereof and including means pivotably connecting said arms to said table at substantially the intersection of said arms with said paddles.
