Abstract
Abstract A vertical feeder for a magazine in a magazine feed apparatus comprises a bell crank pivotally mounted on a shaft secured to a frame for checking up the accommodated article. The bell crank actuates the engagement and disengagement of a ratchet claw in a corresponding ratchet groove provided on a slide member for the magazine receiving rack. The ratchet claw is adapted to be interlocked by means of a link with the lateral stroke of the lateral feeding device for the apparatus for lifting the magazine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
229 words
A vertical feeder for a magazine in a magazine feed apparatus comprises a longitudinally extending frame, a first magazine positioned adjacent said frame, a second magazine positioned adjacent said frame and spaced horizontally from said first magazine, said first and second magazines being aligned for transferring material from one of said magazines to the other, each of said first and second magazines having a plurality of vertically spaced tiers for holding material in a vertically stacked arrangement, means for individually supporting said first and second magazines for moving said magazines in the vertical direction for positioning the tiers in said magazines for removal of the material from one magazine and for inserting the material into the other magazine, means for displacing said magazines in the vertical direction, said means for individually supporting said first and second magazines comprising a vertically extending ratchet groove member having vertically spaced grooves therein, and said means for displacing said magazines in the vertical direction being operatively engageable with said ratchet groove member and being arranged to contact the surface of the material being displaced between said magazines so that when the material in one tier is completely displaced from the one magazine the contacting engagement with the surface of the material is discontinued and said ratchet groove member is engaged for effecting a mechanical lifting of said one magazine by a lever action.

Claim 3
Dependent Claim
120 words
A vertical feeder, as set forth in claim 1, wherein said means for displacing each of said magazines in the vertical direction comprises a bellcrank, a shaft secured to said frame and said bellcrank being pivotally mounted on said shaft intermediate its ends, a roller being secured to one end of said bellcrank and arranged to contact the surface of the material as it is moved from the adjacent magazine, a lever assembly is secured to the other end of said bellcrank and is operatively engageable with said ratchet groove for effecting lifting movement of said adjacent magazine when said roller is no longer in contact with the material being moved from one of the tiers of said adjacent magazine.
Claim 4
Dependent Claim
248 words
A vertical feeder, as set forth in claim 2, wherein said lever assembly comprises a first shaft mounted on said frame, a first lever secured to one end of said shaft, a second lever secured to the other end of said shaft, a feed claw engageable within the grooves of said ratchet groove member and hinged to the end of said first lever spaced from said first shaft, a second feed claw is pivotally connected to the frame and is engageable with the grooves of said ratchet groove member, a spring member for biasing said second feed claw into engagement with said ratchet groove member, a link member connected at one end to the end of said second lever spaced from said first shaft and extending laterally therefrom, a second shaft secured to said frame at a position remote from said first shaft, a feed lever secured to said second shaft and arranged to feed material from one said magazine to the other, a pin secured to said feed lever at a location spaced from said second shaft, and the opposite end of said link from its end connected to said second lever is secured on said pin for transmitting the movement of said feed lever to said second lever and in turn to said feed claw for lifting said magazine after said feed claw is engaged within said ratchet groove member when said roller on said bellcrank is no longer in contact with the material being fed.
Claim 5
Dependent Claim
65 words
A vertical feeder, as set forth in claim 3, wherein said means for individually supporting said first and second magazines each comprising a slide member, a receiving rack secured to said slide member, and one of said magazines being mounted on said receiving rack, said ratchet groove member being formed in said slide for lifting said slide and thereby vertically positioning said magazine supported thereon.
Claim 6
Dependent Claim
35 words
A vertical feeder, as set forth in claim 3, wherein a lever arm secured to and extending downwardly from said feed claw, for pivoting said feed claw out of engagement from said ratchet groove member.
Claim 7
Dependent Claim
103 words
A vertical feeder, as set forth in claim 3, wherein said means for displacing said magazines in a vertical direction comprising a belt lift assembly, said belt lift assembly comprising a pair of spaced rollers, a belt trained over said rollers and connected at one end to said magazine having said ratchet groove member, the other end of said belt member being secured to the other said magazine so that as said magazine having said ratchet groove member is moved vertically upwardly and downwardly said other magazine is moved vertically but in the opposite direction to said magazine having the ratchet groove member.
