Application for reissue filed December 18,

My invention relates to pneumatic feed mechanisms for feeding papers or like articles from the end of a stack or pile.

The objects of the invention are to provide an improved construction of pneumatic feed mechanism of the class specified; to secure rapidity and efliciency in operation; to increase feeding efliciency by relieving the endmost article which is to be fed, from pressure from the weight of other articles; to secure efi'ective action with certain types of papers 01' articles which have not heretofore been effectively fed; to provide advantageous means for holding the articles in proper position for feeding and for releasing them at the proper time; to arrange for feeding the papers or articles when mounted in vertical position; to arrange for the effective advancement of the bottoms of the articles when mounted in vertical position; to permit effective feeding of the tops of the same when in such position; and to secure the foregoing and other desirable results in a simple and expeditious manner.

In the accompanying drawings Fig. 1 is a front view of a pneumatic feeding mechanism embodying my present invention;

Fig. 2 is a. plan view of the same;

Fig. 3 is a View of the right hand end of the machine;

Fig. 4 is a view of the left hand end; and

Figs. 5 and 6 are cross sections taken on lines 5 and 66 respectively, in Fig. 1.

Referring to the drawings, 1 show a series of papers or other articles A-A, arranged side by side vertically so as to make a substantially horizontally extending pile. Where the articles are newspaper sections, the folded edges thereof are preferably uppermost and the cut edges lowermost, as shown 1n Fig. 6. A supporting plate 1 is provided for the endmost articles or papers which are, to be fed, and an upright plate 2 is provided for supporting the endmostartwle and so supporting the stack or pile against falling. Fingers 3 are arranged at the top of the stack or pile so as to engage and hold the upper folded edges of the papers. These fingers are actuated intermittently so as to release the endmost paper, this being done by mount- 1929. Serial No. 415,110.

ing the fingers on the rotary shaft 4 which is rocked byflink 5 pivotally connected at 6 to arm 7 on said shaft, and also pivotally connected at 8 to rocker arm 9, pivoted at 10 and carrying roller 11 which is actuated by cam 12 on rotary shaft 13.

v The papers or articles are advanced forwardly as they are fed by means of a feed or advancing chain. 14 supporting the lower unfolded edges of said articles and travelling over sprocket wheels 15 and 16 on

shafts

17 and 18, respectively, shaft 17 being driven by sprocket arrangement comprising sprocket wheel 19 on shaft 17 and pawl 20 on swinging arm 21 which is reciprocated by link 22 actuated by cam 23 on main drive shaft 24. I

The upper portions of the papers or articles being fed are advanced by a plate 26 slidably mounted on a rod 27, a flexible connector or cord 28 being attached to the slide 29 carrying said member 26 and a weight 30 being attached to the end of the flexible connector 28, which latter is passed over pulley 31 so that the weight 30 tends constantly to pull upon flexible connector 28 and thus push the upper ends of the articles forward.

The endmost article or paper after being released by fingers 3 is engaged and pulled forwardly and downwardly by pneumatic pulling devices or suckers 32 carried by a rotary tubular member 33, which is mounted for vertical reciprocation on a sliding carriage 34, which in turn is mounted at the upper end of a v slidable rod or bar 35 moving in bearings 36. Rod 35 is actuated to reciprocate suckers 32 by swinging arm 37 carried by oscillatory shaft 40, which latter is rocked so as to swing member 37 by pinion 39 on shaft 40 and rack 41 engaging pinion 39. Rack 41 is reciprouated by cam 43 mounted on shaft 24 and

engaging rollers

44 and 45 on link 46 carrying rack 41.

Suckers 32 are swung forwardly and downwardly when their sliding carriage 34 is moved downwardly by means of pinion 48 on tubular member 33, said pinion engaging stationary rack 49. This downward and forward mt Yement of suckers 32 pulls released is further downwardly and forwardly and is then gripped between segment 51 and gripping roll 54, which latteris drivenby gear 55 on shaft 13 and pinion 56 on roll ,zshakft 57. .The gripped paper is.by this.means tween guides 60 and 61 and between delivery withdrawn entirely from;p1le. or [stack of papers and then is moved downwardly beor exit rolls 62 and '63. Ihe latter are driven .by gear 64, which is driven by pinion 56 and gear fi l'drivespinion 65 on roll shaft "66,- and pinion'65 drives pinion 67'on roll shaft 68. Roll shaft68 is mounted inadjustable b'earing69 controlled by spring 70, making roll '63 adjustable to accommodate different thicknesses of paper. To hold upper edges of paper steady in the'pile or stack, pins or'stabbing devices 72 are provided'to nstab or engage the upper folded edges of the papers at proper times.

are reciprocated to engage and disengagethe paper edges, the reciprocation being p'refa for reciprocating-said suckers vertically, and

These devices '72 erably in a vertical manner as by mounting them on the vertically reciprocating rods 73 having pivotal connectionsfat 74 with swinging arms 75 on rock shaft 76, which 7 -35 latter is rocked by arm 77 pivotally connected "with link 78 earring roller -79 andhaving forked end 80 straddling shaft 13, which l'a'tter is provided with cam 81 acting on roller 79-to reciprocate link'78 upwardly anddownwa'rdly, and thereby vertically reciprocate pinjholding devices 7 2.

Tubular member 33 carrying suckers-32 is mounted for reciprocating in bearings 85,

' one of which carries a pipe 86 sliding-in a "pipe, section 87 extending to valve block 88 having ports controlled by rotary valve" 89 actuated by link 90, which is in turn actuated by rocker'arin 91 pivoted at 92 and carrying removed because it is not necessary for it to bear the weight of the'articles above it, as. would be the case in a vertical pile with the roller 93 acted on by cam 94 011 rotary. cam

shaft 13. By this arrangement suction for the suckers '32 is controlled so-that there is suction to engage and pull down endmost paperat proper time, but no suction when or articles in a substantially vertical posi- -ly, and for swinging the same outwardly tion, the endmost article can be very readily articles horizontal." This permits feeding of articles of some kinds which couldnot' be fed properly in the vertical ile. I Furthermore, pressure may be exerte onthese vercooperating with the suc ,tically arranged articles so as to feed them This further simplifies feeding and makes itmore eflicient-and effective. It will also appear that the articles may be effectively held both by the swinging fingers] and the .reciprocatingstabbing or engaging pins, and

consequently any tendency of the articles to fall, or' fiop downwardly will be overcome and feedingwill thus be stabilized in this respect. It will also be seen that the mechanism for engaging and pulling down the endmost article, is effective and 'eflicient, so that altogether a high degree of efficiency and great speed of action may besecured.

"It will be understoodthatchanges and modifications may be made without departingfrom the spirit of the invention.
