The present invention relates to plate feedingand punching means.
More particularly the present .invention relates tomechanism for progressively feeding articles to a pu'nch or the like with a step-bystep movement. The invention will be described with particular reference to mechanism which is suitable for the trimming of the As said grids come kfrom the molds, the edges thereof are unfinished, and it is commonly necessary to ysubjectsaid grids to a finishing operation. This finishing operation is commonly performed in a punch press or the like.
An object of the present invention is to provide a feeding and punching mechanism suitable for the handling of articles such asstorage battery grids, which is positive and rapid in its action and which is readily adjustable whereby the `articles to be trimmed may be presented to the punch press in proper timed relationship with said press.

The numeral 10 indicates a punch press, which punch ress includes the standard 11. Said standard) carries a die adapted to cooperate with a reciprocating punching member, neither the die nor the punching member being illustrated in detail, inasmuch as the details thereof do not constitute the present invention. The punch press may be rovided with the ily wheel 12 and may be riven by means of a motor 13 through any preferred ower transmitting means (not shown).
ounted concentrically with the ily wheel 12 is the gear 14, which may in practice take the form of a sprocket gear driving the sprocket chain 15, which chain 15' drives the sprocket ear 16. The sprocket gear 16, through a eneva movement or other step-by-step power transmitting mechanism, indicated as a whole by the numeral 17, drives a pair of sprocket gears 18-18 constrained to rotate in unison, which sprocket gears in turn drive the sprocket chains 19-19. Said sprocket chains 19 operate again-*endless conveyor, in a manner vwhich will be referred to in detail hereinafter, for progressively carrying grids to the punch press 10. The sprocket chains 19-19 are supported at their extremities opposite to the sprocket gears 18-18 by the sprocket gears 20-20. Idler sprocket gears 21 and 22 are provided for constrainin the sprocket chains 19 to travel in a pre etermined path. Said sprocket gears 21 and 22 are adjustablefor the purpose of taking up slack. Said s rocket gears 21, 22 and 18 are disposed on s afts which are carried by the punch press 10, or other members directly appurtenant thereto. The sprocket gears -20 ma be carried by a frame 23, which is dispose at one side of the punch press 10. Said frame and the punch press provide mounting means for a table 24, which will now be brieflyl described.
The frame 2 3 carries a pair of angle irons 25-25 which are spaced apart and which have flanges 26-26 tially the same plane. Riveted orotherwise secured to the flanges 26-26 are the track members 27-27, each of which carries one of the sprocketchains 19-19. Each of the v flanges 26--26l is provided with a bar 28, which bars 28-28 support thetable 24; the flanges 26, bars 28l and table 24 being riveted or otherwisek secured together. Secured to the'sprocket chains 19-19 at spaced regions along the length of said sprocket chains are brackets 29429 which brackets have secured thereto the cross bars 30-30, each provided 31-73l. As the sprocket chains 29-29 travel in their paths p of movement, the cross bars 30-30 are kept in the driving leasably hold the attaching member 41 in right-angular relationship with said paths of movement. d
The sprocket gear 16 is keyed to the shaft 32, to which is secured the driving element 33 of the Geneva movement 17 The driven element of said Geneva movement 17 is indicated by the numeral 34, which driven element is keyed to the shaft 35. The particular Geneva movement chosen for illustration is a double Geneva movement having the pair of driving pins Bti-36, diametrically dis-- posed relative to one another, and the intermediate arcuate portions 37--37. It will be understood without detailed explanation that pins 36-36 cooperate with the radial slots 38"-38 in the `driven element 34 and that the arcuate portions 37--37 of the driving element 33 cooperate with the arcuate recesses 39 of the driven element 34 'to communicates. step-by-step movement to said driven element 34.
The driven element 34 of the Geneva move- -ment 17 is adjustably connected to the adjacent sprocket gear 18. From an inspection of Figures 4, 5 andl 6 it will be noted that the driven element 34 of the Geneva movement 17 is provided on one side thereof with the attaching member 41. Said attaching member 41 is provided at its two ends with arcuate` slots 41a.-41a symmetrically disposed relative to one another which slots are adapted to receive bolts 4112-411; which bolts are set into the correspondingsprocket 18.
Nuts 410-410 upon the bolts 41b-41b rerigid relationship with theadjacent sprocket gear 18. Set-screws 41d-41d mounted in disposed' in substan-` it is being driven by the motor 13.
against the two sides of one of the bolts 416 permit the accurate circumferential positioning of corresponding sprocket gear 18 relative to the attaching member' 41. The sprocket gears on the two sides of the machine, as illustrated by the sprocket gear 18 meshing with the sprocket chain '19, will be rigidly connected together through the shaft 35. (See Fig. l.)
The upstanding pins 31-31 upon the cross bars 30-30 are adapted to receive battery grids 43 `or other articles to be punched or trimmed. Said grids v43 are commonly provided with holes for receiving said pins 31-31. It will be noted that ydue to the thickness of the cross bars S50- 30, the grids 43-43 are dragged along the table 34with only their edge portions contacting with said table. Expressed in others-language, said grids 43'-43 are dragged 'along the table 24 in angular relationship with the plane of said table. When said grids 43-43 reach the punch press 10, it isvpreferable that they be disposed inv right-angular relationship with the reciprocating punching member of.
said press. Accordingly, the present invention contemplates a diewith afacewhich is inV right-angular relationship with the line of movement of the punching element of the punch press. grids up to the punch press, of course stops short of said punch press. Arranged in position to receive the punched grids after they have left the punch ress is the guide wall 44, which isshape to conform,` to the sprocket chain 19 in advance of thepunch press 10. l
The mode of operationof the above described embodiment of the present invention will be clear without detailed description. The punch press 10 will operate according to well known principles to perform repeated punching or trimming operations as lon has ile the punch press is operating the sprocket gear 14 will be operating in synchronism therewith to drive the sprocket chain 15 and sprocket gear 16 t'o communicate power to the Geneva movement17, which in turn will communicate a step-by-step vmovement to the sprocket chains '19--19 for progressively dragging the grids 43-43 into position to be operated-upon by the punch press 10. By`
The table 24, which carries the.
ing portion he carried in proper timed relation with the feeding of the grids 43-43. Wear in the sprocket chains might disturb this relationship. However, according to the present invention, said relationship may be reestablished very conveniently by operating the set-screws 4lcZ--41d, whereby the angular relationship between the driven element 34 of the Geneva movement 17 and the adjacent sprocket gear 18 may be adjusted.
As shown in Figure 8the sprocket' chains 19-19 have a downward bias from the die of the punch press 10. Expressed in other language, each cross bar 30 after it passes the die 45 of the punch press 10 has a slighttendency to snap downwardly, leaving the corresponding grid 43 in substantially horizontal position upon the face of said die 45. The pins 31 in the cross bars 30`Wil1 preferably be suliiciently long to retain engagement with the grids 43 while the grids are successively disposed upon the die 44. When the punch press 10 operates the grid which happens to be located u on the die 45 is trimmed and also severed a ong a line indicated by the numeral 46, leaving a portion attached to the pins 31-31. The pins 31-31 will carry along the portion of the grid attached thereto until said portion drops ol' at the right-hand end of the machine as the parts are viewed in Figure 1. The trimmed grid, as well as the material severed from the edges thereof, will be propelled across the die 45 and along the wall 44 by the next succeeding cross bar 30 to the right-hand end of the machine as the parts are viewed in Figure 1. Any preferred sorting or dis tributing means (not forming a part of the present invention) may be provided to separate the trimmed grids from the excess material trimmed therefrom.
