The essential elements of this invention are centeredrnrst, and most particularly, in the diamond fold shown in Fig.43,and then as a proper supplement in the mechanism which completes the fold..

It'fwj'll alsofbe noticed; that. they have upontheir'y inside thin .init-1 fairly y rm- -.tongue s.. 1l'. and I2. respectivielfy;v .made of,v stripsvof suitable sheetor other light x metal, the .tongue- 1l extendingfinwerdsome 'f about the mouth ofthe channel betweeithef- .These tongues may be, say, ,im Ainch or more in width, and the 'tongue il 'frst enters the 'blank centrally, so as to Vseparate-fits upper und lower folds, and the tongue l2 lies under"- the cover of the tongue 11 and takes the lower fold, and the two tongues together guide the blank into tho relation and position shown in Figrllt and serve at last, by reasonof their .position and arrangement, n ot only as initial separating-fingers for the sides of the bag or blank, but as the blank slides up to the pinch- 1 ing-point., as in Fig. 14, to hold the' sides at their centersagainst or with the wings 7 and -8, very muchas they 'would be held between the thumb and forelinger of the hand, and their action is precisely the saine as the action of the human lingers would be in the same place to hold the sides of thebag and help to spread them.

Over the upper wing 7 is a springpressed arm 13, which has a bearing through an opening bag andpresses it againstl or upon the inner plate 1.4. v Tof raise this spring-pressed arm whengtheparts are in the position shown in Fig. 1,4, so thatthe bag may move upl into they wings into` proper po'sitiontoA be held and folded, a .bar 15, or its equivalent, is employed,v

which lifts the 'said 'arm momentarily as the .bag slips under. Then as the wings begin to spread or open, the arm 13 at oncebears down 'upon the bag, and' it is held an'd the bottom folding occurs in the manner-described. Now

the further movementof these wings is toward the position shown in' Fig. v18, where they stand in vertical and parallel planes..V To reach this position, I employ a horizontally-sliding frame extending across the machineapd having a base'16, with uprights 17 at its end, and sliding between two upper-and lower guide-pieces 18 onthe 'main frame ofthe machine, as seen in atiter further described.

there is showna connecting-rod l19, pivotally united with the center of-frame 16 at one end and at the other end with the horizontallyrotating arm 20. The arm 20is onau upright -shaft and is actuated'by suitable gear on the shafts 20', 2l, 22, ,and 23, and connecting thence-with the power: `When said crank` armY 2O is turnedat right anglesl to the position shown in Figill, the central foldinglwings Tand `8 are in thev parallel vertical position shown in Figsl and 16, and whenthe said arm hastaken position I1t-.the opposite orot'her extremity of-its throw the frame 16 is carried to the third position andthe-'folding- `wingsy7and Sand the connecting mechanism are-in]thefposition'shown'-in Figs.4 19 and 20.

. I 'have referred tdt'heguide-plates `6 arin thewing 7 upon the top side of the' view, and in-Figfl, side view. vIn Fig.' 11- 12, to allow. this to be done.

rangedimmediately bcforethe folding-wings i l 7 and 8 and as providing a channel orl passage-way for the paper tos'aid-wings. To do their work effectively and to p'erl'orin theft.'-

full function 'these plates should have a mt)- mentary pinching ellect at their free ends at; certain stages of the folding and the upper lone of said. plates should have a backward sliding movement in respect to the other, as

will now appear. Thus, referring to Fig. i8,

we see said plates`6 and 6 supported, respect? ively,on the shafts 25 and 26, the'lower platev being rigid withshaft 26 and the upper pla-'te xed to yoke rotated toward one other the free end of lo wer plate 6 will he raised and the extremities of the plates be brought together to vpinch and `hold the blank, as in Fig. 1S. Rotation of these shafts is effected through a sheave 27', Fig.

v1-1, working ona stretched cable orcord 28;

This sheave is supported in a vertical shaft 29, Fig. 9, and has gear meshing with another gear on the shaft 26. Shaft 26 has gears meshing with gears on the shaft 25, so that when theframe' 16 moves from its startingor first position rearward the said shafts 25 and 26 are rotated toward each other.

3@ 27. Hence when thcshafts are,4 l

The pinching of the blau-kV is necessary in 95 order that the folding may be perfectly accomplished, and the instant that the" said plates 6 cometogether they can of course move no farther, and then as the fra/me 16, carryingisheave 27', movesforwalal to the second and third positions the she-ave necessarily must-slide on the cable '28.

5 p This operation not only continues through` theY operation offoldingthe bottom by means ot'Y the.; l

wings herinbefore described, bu

t' "until their-m5 parts assume 4substantially the-positionseen inFigfQO. In this ligure it will be' observed that thel blank is being delivered to the' endless carriers 3:3 and 33 running over suitable' rolls 34 and 35, and the lowcrplate 6 extends` ldirectlyinto the space between said rolls and carriers, while theupperplate-is drawn back 'inrespectto-thc lower one a suicient distance .to ni-akerooml for the blank to be grasped between the said rolls. ln. Figs. 16 and 2G it willralso be noticed that there-isa' fixed rod 36 centrally over plate 6, which has a stop-pin` through its cnd,'and the upper plate 6 has a stud or post-3.7, having saidfrod sliding-through it. As the parts are carried position shown in'Fig. 2O the-.said stud comes `in contact with saidl piu, aud'then as said forward by the sliding frame '16 toward the frame slid'es farther` along thesaid upper.

plate isdetained, and the saidplate has just enough slidingvmovement in 'its slots 31, Fig. The -saidslots slide on the screws Y 3l atfthc' sides of said top plate G, and which holds it'on l'l'rackets 27'at its sides. In this way the top ,plate-ftfis figo temporarily carried back, asin Fig.' 20;-

' 4Referring to the inechanisnLfor taking the blank from the wings4 at Fig. 20.it will be seenthat the upper rolls 34 and `35 are re-l duced attheir center, while the lower rolls 84 "and are of the same cross-section thrcughrapid, and the actions of the machine involved in the immediatelyforegoing description are vin a sense momentary and can scarcely be observed with the eye because theyare so 'speedy in operation. A leaf-spring 40, `Fig. 8, bearing against the post 37, serves byits own action to carry the tp plate 6 forward f again, so as to bring its extremity again into scf proper engaging relation with .the lower plate 6,l this occurring when the'said parts are moving back toward'tirst position.

The folding-wings, central andside, sup. ported by the carriage 16, are turned primarily by sheaves 42 andv43, which have wound about them the stretched .cords'or cables 44 and 45, Fig. 12. When the carriage 16 travels in either direction the said folding-l wings are turned in one direction or the other, according to the direction of such travel, and

connecting and actuating mechanism. is pro y vided for each'of. said sheaves, as shall now appear. f

Referringto Fig. 21,'it will be seen that upon the carriage 16 there is a b racket lor end support `17, as hereinbefore described, and that in this arm or support is ashzft 47, which has j a square or ..equivalently-formed vbody (seen also in Fig. 9) and is adapted to slide inward and outward within limitations, as the operations of the mechanism require. Uponthis shaft is supported the pulley Vor sheave- 43, lhavinga long inwardly-extending sleeve 48, which goes to the inner extremity of the said shaft 47 and is held thereon by a nut to pre# y vent its coming olf. The shaft 47 has a spindled portion 49, upon which thesheave 43 and its sleeve48 are; adapted to rotate, and they are caused to rotate by the cable or cord 45 about said sheavo, as beforeA described. At the side of 'the sheave43 and on its sleeve is the sheave 42, which has a hub'that turns freely upon the sleeve 48, and the said sheave 42 is prevented from sliding either to the right or to the left and is ,kept in its place to rotate therein by an elbow-arm 50, Fig. y21, rigid with bracket 17 and engaging a groqye in the hub of the slieave 42. This sheave likewise is adapted to turn when the carriage 16 and the sleeve 48 upon which .it rotates are moved back and forth.. It will vbe observed, how

ever, that thesaid ,sheaves 42 and 43 are oppositely wound by their cables, so that they will turnin opposite directions whichever way Ather-carriage moves. Now, it lwill be'further rod 55, which passes through said segment maar seen that the wing 10 has a. sleeve 52, held by a set-screw on the reduced extremity of the sleeve 48, so that it will turn therewith. By

'the side of this sleeve 52 is a segment 54, held within anges or their equivalents `on the sleeve l43 and adapted toturn thereon, and this segment ismade'rigid with the sheave'42 by 'means of a rod 55 fixed in said sheave and passing through said segment. The wing`9,

Figs. 17 and 2l, has a right-angled flange 56,- through whichv it is -tirmlyiixed to the segment 54, and each of the middle folding-wings 7 and 8 has a. right-angled flange, through 8 which it is rigidly secured to the initial extremity of thesaidrods 55. l'

New, observing further the construction disclosed'in Fig. 21, it will be seen that b cth the side folders 9 and 10 are supported on the sleeve 48, but that the wing 10 is rigid therewith and the wing 9 is free to rotate in respect theretoby reason of its control through sheave 42,- rod 'tixed therein, and segment 54. Hence any sliding of wheel 43 back and forth iu respect to wheel 42-as', for example',

from the wheel in full linesto the wheel in dotted lines-fwill carry both wings-back` with it. In like manner the movement ofthe said sheave 43 from the dotted position to the -full position will carry the' said wings -9 and 10 forward, as in Fig. It will furtherv be observed that, since wing 9 is rigid'with segment 54 and middle wing S is rigid with theend of y and is freeto slide therein, the wings 8 and 9 will at all times sustain the same relation to each other in respect to their plane or face, so that if the wing 8 be in one or another of its positions in the three movements herein before described the wing 9A will be in the same relative plane or positionwheth'er it be withdrawn from the bag or participating in the folding operation. It also is clear that since the sheaves 42 and 43, which control Awings 9-and 10, are arranged to rotate in op'- posite directions Athey'will also turn these wings in respect to, each other according te the direction of their rotation. It therefore follows that when the wings 7 and 8 are in a vertical plane, Figs. 16 vand 17, the wings9 and 10 will be so far rotated as to lstand in .precisely the saine plane therewith and they will occupy the position shown in Figs. 1,6, 17, v

and 18, where they overlap the corners 'of the middle wings and produce the half-diamond shaped tuck of the paper indicated by 57 in' dotted lines, Figs. 3` and 5;

lt should be understood that when'all the -wings are at the initial position to begin lthe folding of the bottom of the bag the middle wings engage the edges across the bottom end, as seen in Fig. 14, and then the said wings 9 and 10k are brought practically together side by side and enter near Athe plaits or folds of the 'bag at about the point marked 58., Fig. 2. The two middle wings at the same time engage the, edges marked 59 in said figure. New, as' thewings 7l and S spread toward and
