STACKER FOR FOLDING-MACHINES.
Specification of Letters Patent. Patented Aug. 24:, 1909.
Application filed September 5, 1907, Serial No. 391,507. Renewed January 11, 1909. Serial No. 471,754.
To all whom it may concern: I
Be it known that I, OLIVER W. JOHNSON, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certainnew and useful Improvements in Stackers for Folding-Machines, of which the following is aspecification.
This invention contemplates certaln new and useful improvements in stacking devices and relates articularly to a stacking mechanism for fo ded sheets as they are delivered from a paper folding machine such as that disclosed 'in my application for Letters Patent of the United States, Serial Number 356,278, filed February 7th, 1907.
For a full understanding of the invention,
1 reference is to be had tothe following description and accompanying which: 1
Figure 1 is a side elevation .of a portion of the paper folding machine,-, with my 1rnproved stacker incorporated therewith; Fig. 2 is a side elevation t ereof, some of the rolls being shown in section; Fig. 3 is a detail view of one of the delivery rollswhich form part drawing, in
' of the stacking mechanism; Figgl is a detail top plan view "illustrating diagrammatically the bottom board or base 'of the stacking box; and, Fig. 5 is a detail view of one of the curved guide fingers em loyed.
Corresponding and 11 {e parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters. a I
The paper folding machine with which my improved stacking mechanism is incorporated embodies a series ofrolls NIB and C extending in horizontal planes in a triangular arrangement, as shown, the paper being pressed downwardly between the rolls A? and C into a folder 9 6 which is provided -with a bed late 97 for the sheet, said bed plate being etachably held by means of a set screw 97.
As the sheet passes downwardly between the rolls A and G into the folder, it is arrested by a stop device .96 .and'th-us caused to-buckle. downwardly between therolls A and, Chit will buckle in an evident manner and be caused to pass downwardly in folded condi- .tion between the rolls C and B which thus, constitute the crimping rolls of the ser1es. These rolls are driven in anysultable manner As the sheet continues to be fed A folded sheet is delivered from the rolls l3 and C and is engaged by means of a series of curved guide fingers 94 that are all supported by means of a transverse bar 95 secured to a portion of the folding machine framework. These curved guide fingers 94 are spaced from each other and direct the foldedsheet down into and between the delivery rollers 92 and 93 of the stacking mechanism. The roller 92 is fluted, as clearly illustrated in the drawings and receives its motion from any shaft of the folding machine, by means of a sprocket connection 91.
The paper finally passes down into and between upright stacking arms 98 and 99, the arms 98 being stationary and extending up past the two rollers 92 and 93 by meansof grooves in the roller 93, while the stacking arms 99 are relatively movable. The lower ends of the stationary stacking arms are held within brackets 101 which are formed with upper and lower series of wheels 103'upon which the base 102 of the stacking box is mounted to travel in justable platform 104, which is held by means of set collars 104 upon fingers 99 and coacting upri hts 105 that are secured to the ends of the base 102. The base 102 and platform 1.04 are each composed of a plurality 0f longitudinally extending ,boar'ds spaced from each other, as best seen in Fig. 1 or are otherwise formed with channels or slots to accommodate the arms 98, so that the said base and platform together with the relatively movable stacking arms 99 may be moved outwardly to effect the extension of the stacker as the sheets accumulate. The upper ends 100 of the stacking arms 99 are curved outwardly as shown.
a horizontal plane. This base 102 supports the vertically ad- In the practical operation, as the folded I sheet engages the guides 94, it is thereby ,de flected downwardly and received in the fluted roller 92 which moves at the same surface speedras the delivery rolls C and B of the delivery device. At this point, the sheet is fed into the-two rollers 92 and 93 on down until the advance edge engages the stacking arms 99 and 98, and on down until the said edge reaches the platform 104 .of the stacker. This platform is so set previous to the arrival of the sheet that it will be far enough from 1-10 ment of the two rolls.
a naturethat they will hook over the edge of the sheet and as the roll continues to turn around, it will force the sheet to bend downwardly until the; lower edge engages the'platpull the sheet upwardly the sheet still too high form 104. This should leave the top edge of to escape'th'e bottom periphery of the roll 92, so that the flute will continue to exert the same influence over the edge'and cause itto be shoved to or delivered on the rear side of it. When it finally becomes clear of the said flute, thenit has been bent backwardly against the curved up er ends 100 of the rods 99 with the roll 92 etween it and the place it formerly occupied-. It, therefore, follows that itcan never'ieturn to its former osition and thus room is left for the next s eet to enter. If it is desired that the sheet be fed directly to the stacker from a folding mechanism above the rolls A B3 and C this result may be accomplished by merely removing the set screw 97 and de taching the late 97 which it normal 11K holds. It is t en obvious that the sheet be fed downwardly through the rolls A? and C and be delivered directly to the stacking a rms.
As best illustrated in Fig.1, it will be seen that the fluted roll 92 is grooved like the complemental roll 93, and that the guide fingers 94 extend downwardly and rest with their lower ends in the grooves 92 of the roll 92. The lower ends of the guide fingers 94 are recessed as indicated at 94: so as to artially encircle. the shaft of the fluted ro 92 and the lower end of the respective guide fingers are formed with convex heel portions 94* as best seen in Fig. 5. Without the provision of these parts described, the paper when stacked would, when the stacker was partly full, press so hard against the fluted roll 92 after the upper edge of the sheet had been thrown bak that the said roll would and thus disarrange it.. By the provlsion of the heel portion94 of each guide finger 94, the sheet is held away from the roll when delivered from the latter. and cannot come in contact with the roll 92 after it has once been released therefrom.
B reference to Fi .4, it will, be seen that the ottom board or ase 102 of the stacking box tapers toward its rear end. Small rollers 103 are provided to bear against the side edges of the said base 102, (Figs. 2 and i) the said rollers being arranged to rotate about vertical axes and mounted in pairs, front and back. When the stacker fills up and moves The flutes are of such away from the complemental rolls 92 and 93, the wedge or tapering shape of the'base 1.02 will manifestly permit the removal of all friction during the operation and when it is start true at every 0 eration. Havingthus descri ed theinvention, what is claimed as new is z. A v 1, In a aper folding machine, the combination wit a folding mechanism, of a stacking box adapted. to receive the .folded paper and embodying a base, roller supports upon which said base is horizontally movable, a vertically adjustable platformsup orted by the base,1r elatively movable stac -ng arms extending above the platform," and relatively stationary stacking arms ,the platform being slotted and the stationarystackin arms extendihg through said slots, where y to permit the extension movement of the base and platform.
