. fication.

M/y invention relates to a new and original machine for folding sheets of paper of different sizes and with various folds, all substantially as shown and described and particularly pointed out in the claims.

Figure 1 is a side elevation of the machine. Fig. 2 is a vertical sectional elevation of the machine with the parts corresponding to Fig. 1. Fig. 3 is a side elevation of the machine at right angles to Fig. Fig. 4 is a rear elevation of the machine. Fig. 5 is a sectional plan view of the machine corresponding otherwise to Fig. 3. Fig. 6 is a cross sectional view of the group of creasing rolls through which the paper passes successively as a last step after being folded and when otherwise ready to be discharged from the machine and of other parts associated operatively therewith. Fig. 7 is a sectional elevation of the machine corresponding in the main'to Fig. 2 but with certain folding or tucking parts rotated to right angles as compared with Fig. 2. Figs. 8 to 16 inclusive are views of sheets of paper showing some of the fold lines possible with this machine. Fig. 17 is a face View of one of the plates WV in full linesand showing a possible modification in dotted lines.

The object of this machine is more especially to foldrelatively small sheets of paper, such as ordinary letter head, legal cap and like sheets, larger or smaller, but is not necessarily limited as to sizeof paper, so that printed sheets, circulars and the like within the size of a given machine can be folded as rapidly as they come from the printing press and creased and delivered for any further purpose. It may be said that for ordinary purposes the machine is neither largenor expensive, and does not exceed say two by three feet in plan, or smaller, and correspondingly small in elevation.

Referring now to the various parts, A represents the main frame of the machine and S the power or drive shaft, provided in this instance with a hand wheel W to rotate the same and operate the machine, but power may be used instead and be applied in any available way.

The top 2 of the table is of sheet metal, preferably, and constitutes a rigid portion of the main frame of the machine. Said top has a transverse slot or opening co-incident with vertical opening or slot 3 and which slot is adapted to receive and direct the sheet of paper folded by blade 6 down into Patented Oct. 11, 1910.

position to receive a second or double fold at transverse slot or opening 4: or through vertical slot 5. Said slots 4 and 5 have the form of a Maltese cross see Fig. 17 and both are adapted to receive blade 7 according to its adjustment as will presently be seen.

The operating parts entering into the first and second foldings above mentioned comprise the blades 6 and 7, respectively. Blade 6 is removably supported at its ends in rackbars R arranged vertically on opposite sides of the machine and adapted to run up and down with a reciprocating movement, like a sash, in suitable guide-ways in the machine frame. The operation of said rack-bars is effected through a line of gears presently to be described. The travel of blade 6 is fixed by the travel of the rack-bars, and its fullest possible depth of stroke is down to the bottom of slot 3 between the side walls W. The cross slots 4 and 5 are through these Walls, and While blade 6 is adapted to run only in slot space 3, the blade 7 is rotatable upon its axis and may enter either with a supporting cross head H and a stem or shank E rotatably mounted in a bearing J in the main frame. Said bearing has an arm 71,, and a set screw 72. is engaged through a curved slot in plate 10 splined on said stem E and adapted to fasten said head in any rotary adjusted position of said head and its blade 7. The said stem or rod E is designed to receive a direct. operating thrust to carry the paper engaged by blade 7 into receiving position between the initial creasing rolls 12, and said thrust is effected through a suspended or swing arm F, having a transverse slightly curved slot 13 between its ends and at one end of which slot there is a side projection or roller 14:, adapted to be operatively engaged by a cam 15 on shaft 16. As said shaft and cam rotate the cam engages said projection 14 with each revolution and swings said arm forward with a thrust movement for blade 7. Said stem or spindle E is rotatably supported in a small b ock 17 engaged on trunnions in bearings in the lower extremity of arm F, and is confined therein by a nut on its outer end and a shoulder on its inner portion bearing against said block, and a spiral spring 18 on shaft E between said block 17 and plate 10 throws said blade 7 back to initial position when cam 15 has done its work. So it occurs that the second in the series of three folding blades is adapted to roduce a second fold in a once folded sheet by entering either slot 4 or slot 5 according to its position, and to this end is rotatably mounted in bearing J as above described and locked in either or any adjusted position b screw k. If for any reason the initial fo d is not to be made by blade 6 said blade is removed and then the the unfolded sheet in slot 3.

The rotatable setting of blade 7 to different angles of work implies a like capability of change in the single initial set of creasing rolls 12 which always work therewith and receive the paper from blade 7 in either or any of its positions. Thus, in Fig. 1 said blade is shown as standing vertically in front of vertical slot 5 and rolls 12 are vertical likewise, while in Fig. 7 said blade is horizontal and said rolls 12 are horizontal also, and the successive creasing rolls 19 and 20, and idler 21 and stackers 27 and 31 change with rolls 12 as will now be seen. Thus, G represents a rotatable supplemental frame in which said rolls are mounted upon shafts engaged at their ends in said frame, and a trunnion or spindle g at the cente1- of said frame axially opposite spindle E of blade 7 has a bearing in the main frame of sufficient depth and strength to operatively support said frame and the parts thereon in any adjusted position. Then in order to fix said frame G when rotated I employ a bolt 22 engaged throu h any one of the three several holes'm accor ing to position. This provides for both a quarter and a half turn of said frame G, which in the latter case reverses the osition of the rolls and other parts from t at shown in Figs. 1 to 6 inelusive. Assuming, now, for better understanding of the operation, that the said roll carrying or supplemental frame G has been rotated from its most frequent using position, as in Figs. 1 to'6, to position, Fig. 7 with the said rolls horizontal, the thrust of blade 7 through slot 4 will carry the sheet or paper into the bite of rollers 12, when said blade is immediately retracted. If there be no further folding to do when the paper has passed through said rolls 12 it is directed to one side by means of a combined stop and first fold will be made by blade 7 with guide 24, Fig. 6,.in the direction indicated by the arrow, and in this travel the paper is engaged by the star wheel 27, termed a stacker, to deliver the same at one side.

But in the event that still another fold is to be formed in the paper the guide 24 is swung to or toward stacking wheel 27 see Fig. 7 so as to allow .the paper to pass directly forward past the same into tucking position for blade 28 and engaging relation between the second set of creasing rolls 19 and 20. Said so-called tuckingor folding blade 28 is carried by arms 30 supported and operated as hereinafter described and is'adapted to produce the third fold of the sheet or paper which has been passed on from blades 6 and 7, and from rolls 19 and 20 the folded sheet is discharged between'idler 21 and stacker wheel 31- working together. It will thus be seen that at least three different and distinct folds for a given sheet are directly provided for in-this mechanism with the necessary creasing of the sheet on all the fold lines successively, rolls 12 creasing the fold made by blade 6 as well as that made by blade 7, and direction of the second and third folds as compared with the first by blade 6 depends on the positions of blade 7 in respect to slots 4 and 5.

Obviously there are numerous details in connection with the construction and operation of the parts just described which have been passed over and will now be considered. T bus, as a means of operating the rack-bars R which carry blade 6 Iprovide rcversely rotatable gears 36 36 mounted on frame A and meshing with said bars. Said gears are adapted to rotate in reverse directions a given distance successively and are driven from power shaft S by gear 38'tl1ereon meslu ing with ear 39 on crank shaft 16, Figs. 3 and 5, and wh ch carries the actuatingwsam ment with pinion 43. Then in order that the 'two rack-bars R for blade 6 shall work uniformly together I interpose a shaft 44 and place gears 37 and 37 of the same size thereon on opposite sides of the machine and thereby reach rack controlling gear 36 on the opposite side of the machine and which corresponds to gear 36 on the initial side of the machine and meshing with gear 37. Gear 36 is thus made to engage one rackbar R directly and the other of said bars indirectly. Again, the several paper creasing shaft and through numerous intermeshing gears as seen in plan, Fig. 5. As to these gears it may be said in advance'that they may be more orless variously related or geared up one with another and still work out the desired rotation of said rolls, but in this instance I-have followed an apparently natural order of'selection and transmission and which proceeds from or through the shafts 46, 47 and 48, Fig. 5, to gear 50 as the initial gear in the planetary group. Said several shafts 46, 4:7 and 48 are operatively connected by bevel gears at their ends, and shaft 46 is connected with like gears with main or power shaft S, so that when the said shafts rotate the creasing rolls and staekers operated thereby are rotated also. From initial pinion 50 in the group transmission proceeds through pinions 51 to 52,.

" and then from 51 through idler 53 an pinion 51 to roll 20 and pinion 54 to stacker 31. Again, a line of actuating mechanism for the third blade or tucker 28 isprovided as hereinbefore indicated so as to actuate said blade in timed relation with preceding parts, and consists in a shaft 60, Fig. 5, which has bevel gear connection with power shaft S to drive the same and is provided with a cam 61 at its other end which engages the end of a tappet rod 62. Said rod en gages arm 30 on one end of a vertically disposed rod 64 mounted in frame G with a thrust movement and which shaft has an arm 30 on its other end corresponding to arm 30, and the third folding blade 28 is fixed somewhat freely in or to these arms at its ends so as to get the desired action. Said arms with their blade have a limited swinging or oscillating movement together, first tocarry said blade to tucking position between rolls 19 and 20 and then back under the action or effect of spring 65 on axially rotatable rod or shaft 6% which carries arms 30 and 30, see Fig. 2. The tappet rod 62 is itself loosely mounted in a sleeve resting on trunnions on frame A, so that said rod can be removed or swung out of the way when the creasing rolls are rotated to position Fig. 7. Then cam 61 actuates tappet rod 72, Fig. 4, and which engages a pivoted lever 73 adapted to engage arm 30 of the tucking blade 28 in the same place and way as said rod 62.

An adjustable stop 35 is shown as adaptedto run in slot 3 for the paper and serve as a stop therefor-when needed. as in the case especially when unfolded Sheets are introduced in said slot.

Respecting the walls "V, the said walls may have any suitable construction and be of any suitable material, the need being that they should hold the paper in either single sheets or with a single foldimparted by blade 6, and the two walls need not necessarily be alike but the walls next to creasing rolls 12 must be such as to enable the paper to be thrust through the slot or slots therein by blade 7 and assist in the folding of the paper as this occurs. Likewise any suitable top 2 may be used, as well as suitable paper guides 75 and a stop plate 76. Top 2 is slotted transversely to permit guides 75 and their lock nuts 77 to be laterally adjusted and whereby the paper may be variously placed'relatively to vertical slot 5 in plates V and also to blade 7, and stop plate 76 is also adjustably secured to top 2 by lock nut 78 in slots 79 in said plate and top 2, respectively. Plate 76 is thereby adapted to be set at any given point on table top 2 to stop the paper so that it may rest in any desired position relatively to slot 3 and blade 6, and whereby the first fold may be made at any given point in thepaper between its side or end edges and dependent upon whether it is fed endwise or sidewise thereto. Blade 6 is also adjustably secured vertically in slots 1 in rack bars R by thumb screws 1' or their equivalent. Thus blade 6 may be variously set so that it will fold and deliver a sheet of paper with its fold line at different elevations relatively to the horizontal slot 4 in plates W, thereby providing for variations in further folding operations by blades 7 and 28, respectively. By these means the fold lines can be made in any portion of the sheet P and in either or both directions thereon as may be desired, such, for example, as is seen in Fig. 12 which shows a single fold and which is produced by blade 7 passing through slots 4 and doubling the sheet at its middle and then discharging the same through casing rolls 12 by stacking wheel 27. Fig. 10 shows a double fold and wherein both blades 6 and 7 participate and the paper is discharged by stacker 27 as before. Fig. 11 illustrates a three-fold, and in this case the sheet is so fed to the table that blade 6 will strike the paper off center and then blade 7 will strike on one of the two cross fold lines and carry it into position to be folded upon the other line by blade 28 and discharged past stacker 31. Fig. 13 illustrates a form of fold wherein all three of the several blades participate and represents an eight page fold adapted especially for booklets. in this case the fold line'aa is made by blade 6, and the fold line 5-?) by blade 7. This represents a four-fold sheet until blade 28 strikes the same in the middle and which corresponds to line 0-0 and tucks the paper into rollers 19 and 20, whence it is discharged by the stacker 31. Numerous other folds are possible with this mechanism, as is also in part illustrated in the several undescribed views and which folds would appear obvious from the foregoing description and need not therefore be more particularly referred to. Other folds also are possible, as likewise would appear obvious.

Cross reference is made to a joint application filed by Alburt I). Pejauo and John J. Zeitz, Ser. No. 581,521, which contains some of the features of construction and operation embodied in the present invention and is an improvement thereon and not in conflict therewith.
