PAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 640,571, dated January 2, 190.

Application filed August 2 '7, 1 8 9 7.

To all wiz/om, it may concern:

Beit known'that I, HOWARD K. KING, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of Which- Figure 1, Sheet 1, is a plan view, the packing-trough beingin one position 5 Fig. 2, Sheet 2, a rear end elevation; Fig. 3, a side elevation; Fig. 4, Sheet 3, a section as on line w w, Fig. 2, but showing the packing-trou gh in the other position at right angles to that shown in the preceding figures; Fig. 5, Sheet 1, a vertical section on line cc, Fig. 2 5 Fig. 6, Sheet 1, a full horizontal section on line y y, Fig. 3; Fig. 7, a horizontal section on line z c, Fig. 3.

This invention relates to that well-known class of folding-machines wherein the sheets of paper fed into the machine are carried by tapes over folding-rollers and are tucked into the bite of the latter by vibrating blades and the iinally-folded-sheets fall into a packingtrough. It is sometimes desirable to give to the sheet a final fold by a set of rollers and sometimes to carry it over from the latter to another set of rollers, which impart an additional and lnal fold to the sheet at right angles to the previous fold.

The main object of my invention is to provide, in combination with the said two sets of folding-rollers, a single packing-trough adapted to be used in connection With either set and means for imparting the usual reciprocation to the plunger of the said trough, the arrangement and construction being such, as hereinafter described, that the trough is adapted to be turned to either one of two positions at right angles to each other in order to bring it into proper line for the reception of the folded sheets coming from the one or the other set of folding-rollers, as may be required, and` at the same time permitting of the proper operation of the plunger and its actuating mechanism in either position of the trough.

Referring to the accompanying drawings, in which are shown only such parts of a folding- Serial No. (549)702. (No model.)

machine as I deem necessary to a clear understanding of my invention, lis the main frame of the machine; 2,the main shaft,which is driven from a suitable source of power and which through gear connections 3 and 4 drives a shaft 5, Vthat actuates the foldingblades and also the plunger of the packingtrough through intermediate mechanism, such as hereinafter described. As the means for operating the said blades are Well known and form no part ot' my invention, I shall not describe the same.

6 is a set of folding-rollers, and 7 is a similar set of rollers disposed at right angles to the former, as seen most clearly in Fig. 1. These setsV of rollers are driven and operate in the ordina-ry way.

8 is the packing-trough, which is mounted about midway of its length upon a vertical rotatable cylindrical post 9, or more precisely upon the end of a bracket 10, Figs. 2 and 3, extending from the latter in such position, as shown, with relation to the rollers 6 and 7 that when it (the trough) is at right angles to one set of rollers it will be in position to properly receive the sheets from that set and when turned on its pivot at right angles to the second set of rollers it will likewise be in position to receive the sheets from that set.

11 is the usual reciprocative plunger (shown in Figs. 2, 3, and 4) Yand which in this instance is adapted to pack both ways. The plunger-rod 12,which extends lengthwise with the trough and is adapted to slide in the usual guideways projecting from the trough, is connected to an arm 13 by a rod or pitman (not designated in the drawings) running beneath the trough and pivoted to a stud depending from the plunger-rod 12 and to the free end of the arm 13, respectively, as seen in Fig. 3 and indicated by dotted lines in Figs. 1 and 4. The hub 14 of arm 13 is journaled on a vertical stud 15, that is ,fixed to the top or head of post 9 and is connected with the latter. Hub 14 h as also two arms 16 and 17, respectively,which are substantially at ri ght, angles to each other, as a bell-crank.

18 is a vertical rock-shaft journaled in bearings of a part of the machine-frame. 19 are IOO two arms projecting from this shaft and con- 21 is a horizontal pitman, one end of which is loosely pivoted to rod 20, so as to be capable of sliding thereon, and its other end is adapted to be pivoted interchangeably to arms 16 and 17 by means in the present instance of a pin 22, that is adapted to be passed through lugs or bifurcations 23 of either one of the said two arms and also through an aperture in the end or cross-head of the pitman.

The rock-shaft is oscillated by means of an ordinary strap-eccentric 24 (indicated by dotted lines in Fig. 3) on the rotatable shaft 5 through an arm 25, one end of which is fixed to said shaft and its other end is connected to the strap of the eccentric bya rod 26, that is suitably pivoted to the latter and to the arm 25, as shown.

For taking up lost motion I employ a spiral compression-spring 27 on a rod 28, one end of which is pivotally connected to an extension of rod 20, and its other end is adapted toslide in a suitable guide (not shown) of the frame ofthe. machine, the spring bearing against a head 29 on the said rod 28 and against the guide.

The sheets fed into the machine to be folded and packed are carried in the usual way by tapes (not shown) and are stopped bya suitable stop (also not shown) in position over the folding-rollers 6 to be tucked between them by a folding-blade B, and the packingtrough having been disposed at right angles with said rollers, as in Figs. 1, 2, and 3, the sheets Will successively fall into the trough and will be packed therein by the reciprocating plunger through the action of the eccentric 24 and the described chainof mechanism intervening between the latter and the plunger., When the trough is in this position with relation to the rollers 6, the pitman 21 is oonnected to the arm 16, as shown in the said figures. If, however, it be desired to give an additional fold at right angles to the first fold to the sheet that has passed through the rollers 6, I carry the sheet as it leaves these rollers, by means of suitably arranged and` driven tapes running over the said rollers in the usual way in foldingmachinesover to and above the other setof rollers 7Which are in a lower horizontal plane than the other set, and the sheet is tucked between rollers 7 by a vibrating blade C. Vhen this additional or second fold is not required, the said tapes are notused-that is to say, they are removed. In preparing to carry the sheet between rollers 7 I first disconnect the pitman from arm 16 by withdrawing the pin 22, then,

swing around the packing-trough on its pivot (the post 9) toa position at right angles to its previousposition-that is, at right angles with rollers 7-and then connect the pitman with the other arm 17, as seen in Fig. 4.

It will be obvious that by the construction andarrangement hereinbefore described the plunger will be properly reciprocated in either position of the packing-trough.

As the batches of sheets to be folded and packed may vary in size, it is desirablel that the trough be capable of being adjusted vertically in order to insure the proper reception of the sheets as they descend into the trough without affecting the operation of the plunger-actuating mechanism. This adjustment may be readily effected by the construction shown in the drawings and now to be described.

The post 9 is adapted to turn in a box or bearing 30 of a cross-bar 31 of the frame of the machine. At oneside of the box is a vertical slot 32, into which is entered a toothed rack 33, that is confined at top and bottom by and between peripheral flanges 9 of said post, the inner edge of the rack resting against the latter, constituting a part, so to say, of the interior circumference of the box. Thus when the post is rotated the rack cannot rotate with it. 34 is a pinion whose shaft 35 is. journaled in a cylindricall box 36, :fixed to. the cross-bar 3l, and whose teeth engagethose of the rack. By turning a hand-wheel 37 on the end of the pinion-shaft the rack, and consequently the post and so the packing-trough, may be raised or lowered, it beingmaintained at any adjustment by means of a suitable stop. device-such, for example, as by a ratchet-wheel 38 on the said shaft and a pawl 39, pivoted to the box 36. As the pitman 21 slides on the rock-shaft rod 20, when the trough, the., are moved vertically it (the pit-V man) is capable'of performing itsv function at any and all adjustments of the packing trough.

I remark that it is advisable to limitr the extent of rotationof the pivot-post in order to insure the properspositionsof the packingtrough with relation to each set of the folding-rollers. For this purpose I employ two studs 40, that project from the top of the lower flange of the post andare so disposed, as shown, that one of them will strike'against the side of the rack 33 when the trough has reached one of its positions and the other against the opposite side of the rack when the trough has been turned to the other position.

Referring to Fig. 3 of the drawings, it will be seen that. there is a set of rollers (marked 41) similar to rollers 6 andr located directly beneath the latter and substantially in the same horizontal plane as rollers 7. The sole purpose of these rollers 41 is. to carry the dropping-pointof the sheets from the rollers 6 nearer to the packing-trough, so that they will not fail to take their proper position in the trough-in short, to cause the sheets to drop substantially the samedistance whether they are folded by rollers 6 only or also by rollers 7, for as the sheets pass from the former rollers 6 they enter between the rollers 4l, and thence fall into the trough. These supplemental rollers may, however, sometimes be dispensed with.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a folding-machine, the combination of the two sets of folding-rollers and the horizontally-rotatable packing-trough, all relatively arranged as shown and described, the plunger, the arm connected therewith and pivoted to a suitable support, the two arms at right angles with each other and connected with the first-mentioned arm, the rock-shaft, means for oscillating the same at predetermined intervals,together with the pitman connected with said rock-shaft, and adapted to be pivotally connected with either one of said two arms, substantially as and for the purpose set forth.

2. In a folding-machine, the combination of the two sets of folding-rollers and the horizontally-rotatable, vertically-ad j ustable packing-trough, all relatively arranged as shown and described, the plunger, the arm connected therewith and pivoted to a suitable support, the two arms at right angles with each other, and connected with the first-mentioned arm, the rock-shaft, means for oscillating the same at predetermined intervals, together with the pitman having a vertically-sliding connection with said rock-shaft, and adapted to be interchangeably connected to either of said two arms, substantially as and for the purpose set forth.

3. In a folding-machine, the combination of the two sets of folding-rollers, 6 and 7, and the horizontallyrotatable and vertically-adjustable packing-trough, all arranged relatively as shown and described, the plunger and means for actuating the same in any of the vertical or horizontal positions to which the trough may be adjusted, together with the supplemental set of rollers between which the sheets folded by said rollers, 6, are adapted to pass and thence drop into the packingtrough, substantially as and for the purpose set forth.l

4. In a machine of the character described, the combination of the rotatable, verticallymovable post, the packing-trough secured thereto, and means for adjusting vertically said post, the same consisting of the non-rotatable rack connected to said post, the rotatable pinion/engaging said rack, and means for maintaining said post in any adjustment thereof, all constructed, combined and adapted to operate substantially as and for the purpose described. f

5. In a folding-machine, the combination of the two sets of folding-rollers, the rotatable and vertically-adjustable post, the packing-trou gh secured thereto,the plunger adapt ed to reciprocate in said trough, the arm pivoted to said post, substantially concentric therewith, and having its free end suitably connected with said plunger, the two arms substantially at right angles with each other and connected to the first-mentioned arm, the rock-shaft, means for oscillating the same at predetermined intervals, and the pitman having a vertically-sliding connection with said rock-shaft and adapted to be interchangeably connected to either of said two arms, substantially as and for the purpose set forth.
