PAPER-FOLDING MACHINE.

Application led May 1,

To all whom t may concern.'

Be it known that we, WALTER Gr. TRAUT- MAN and EDWARD K. DANIELs, citizens of the United States of America, residing at Cleveland Heights and Lakewood, respectively, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a specification.

Our invention relates to improvements in paper folding machines and has for its object the provision therein of means for alternatively directing the sheets or signatures to the stacking appliance o-r into the transverse conveyor of .said machine with the least practicable expenditure of effort and time.

The present improvements are directed toward the adj ustment of mechanism readily associated with the folding rolls of a paper folding machine, whereby said mechanism may be caused to assumer three positions; the one directing the signaures or sheets immediately to the stacker; the second conveying the sheets past the position of deflection toward the stacker to the transverse conveyor, f and the thi-rd positioning said mechanism so that it may be readily inspected and any necessary attention may be given thereto without delay or difficulty of any sort.

Initially describing the embodiment of our improvements, in brief, we may exlain that the stacker normally is positioned in t-he frame of the paper folding machine immediately above the transverse conveyor mechanism during the reception of the sheets by the stacker, meanwhile the apparatus of the conveyor is temporarily disabled and out of use. An adjusting lever positioned at one side of the frame is adapted to actuate the delivery rolls for the stacker into and out of operative engagement with the driving train of the paper folding machine.

Alternative to the foregoing operative position of the apparatus, the stacker mechanism may be bodily removed as a unit from the frame of the paper folding machine and the lever mechanism is thereupon connected with an auxiliary set of delivery rolls and mechanism which are brought into position immediately associated with the transverse conveyor, and the signatures will be carried 1924. Serial No. 710,436.

upon said conveyor and delivered at one side of the paper folding machine, usually for the purpose of making one or more transverse folds in the signatures.

The features of our improvements may be more readily explained and understood by making reference to the accompanying drawings wherein:

`Figure 1 is a view of the paper folding machine embodying our improvements, shown in side elevation;

Fig. 2 is an enlarged fragmentary detail thereof Ibut shown partially broken away and with an alternative position in dotted lines, bet-ter to explain the structure and operation of the particular mechanism embodying our improvements;

Fig. 3 is a transverse section on the irregular line 3-3 Fig. 2;

Fig. 4L is a fragmentary longitudinal section on line le-4c Fig. 3, showing the mechanism in position for delivering the signatures directly to the transverse conveyor;

Fig. 5 is a similar ,sectional view wherein the stacker is shown in posit-ion and the delivery rolls for the transverse conveyor are disabled; and

Fig. 6 is a fragmentary detail section on line 6 6 Fig. 4, illustrating means for connecting and disconnecting the transverse conveyor rolls to and from the actuating lever.

Throughout the several figures of the drawings we have employed the same character of reference to indicate similar parts.

Referring first to Figs. 4 and 5, which, we may say, are somewhat diagrammatic, better to illustrate the function of my improved mechanism, the frame a is therein shown supporting the rolls Z)- of the feed table adapted to actuate the sheets or signatures through the throat b to the series of folding and buckling rolls c, d, e, f, g and It. The associated folding plates z', j, le and Z are horizontally positioned with their throats adjacent to the respective folding and buckling rolls for producing one or more transverse folds in the sheet in accordance with the usual practice. Each of said folding plates is provided with a pivoted deflector member i', j', c and Z of suitable shape adapted, individually, to be adjusted before the throats of said folding plates if, one or more is to be disabled and temporarily rendered out of use. In the particular adjustment of the apparatus shown in Figs. 4 and 5 the deflector members are positioned before the throats of the respective folding plates, excepting only j', which is turned back upon the up-per portion of the folding plate at the right7 thereby rendering it operative toi produce a single transverse fold in the sheet; all this being particularly described and claimed in a co-pending application (Patent No. 1,534,885, April 2l, 1925) and requiring no further reference for the purpose of explaining the present improvement.

Two separate sets of rolls m, m and n, n are pivotally mounted upon the shaft 0 and these are adapted to be independently act-u ated into and out of position as alternatively shown in Fig. 2 by full and dotted lines. Said shaft 0 is provided with an actuating lever 0 and the arm m duplicated at both sides of the machine is splined directly upon said shaft o so that the rolls m, m invariably are actuated upon the movement of the lever 0. On the contrary the rolls n, n, together with the converging throat p, are mounted upon the arms n, also duplicated at both sides of the machine, and these are adapted to be actuated as a unit independently of the first named rolls, by connecting or disconnecting them through the medium of the spring bolt g upon arm n which extends normally into a registering opening g in arm m but is adapted temporarily to be released therefrom so that the rolls n, n will remain upon the stop r and temporarily disable the transverse conveyor.

With these features in mind we may now explain that the stacker s (Fig. l) is removably positioned within the frame so that the gears s are in mesh with the auxiliary driving train designated by b. Said stacker is provided with the usual belt conveyor s, sectionally shown in Fig. 5 in position to receive the sheets as they are delivered by the rolls m, m. This mechanism requires no further description since it otherwise conforms to the usual and well-known practice.

Immediately beneath the stacker, but alternatively operated with respect thereto, are permanently positioned the frame t and rolls t of the transverse conveyor which are operatively associated with the delivery rolls n, n. lVhen these rolls are in the position of Fig. 4, the stacker s then being removed, it will be seen that the folded signature will be passed upon the transverse conveyor rolls t in the usual manner and will be carried toward the opposite side of the folding machine, as into cross-folding plates and rolls u, u (Fig. l).

The present improvements, however, are confined to the relation of the mechanism respectively adapted for stacking the initially folded sheets or for conveying said sheets alternatively into another operative position of the paper folding machine which may now be detailed with the structures above described in mind. Thus, referring to Fig. 5, the sheets will be fed one by one from the feed table b and through the throat b into the series of folding and buckling rolls; being once folded in the folding plate j but deflected from between the other rolls of the series to the advancing or delivery rolls m, m and from thence upon the belt s of the stacker which will stack the sheets in the usual manner, not necessary to explain herein. It may again be noted that the rolls ln, n are meantime resting in their lowermost position to disable the transverse conveyor.

Upon adjusting the mechanism n, n upon the arms a and shaft o to its operative position of Fig. 4L, the stacker device now being removed as previously explained, it will be appreciated that the signatures will be delivered by the rolls m, m into the throat 29 and between the rolls n, a which will pass said signatures directly upon the rolls t of the transverse conveyor and thence toward the opposite side of the machine or into the folding plates and rolls u, u', as assumed in the foregoing description, although any other operation may be performed upon the signature as shall be speciically provided for any particular machine. Accordingly the paper folding machine is equipped for ready adjustment by means of the actuating lever, and the insertion or removal of a cooperating stacker, to be used with one or both sets of feeding rolls; the adjustment being very simple and quickly accomplished by the improvements shown and described.

Having now described the preferred embodiment of our invention and explained the function thereof, we claim as new and desire to secure by Letters Patent, the following:

l. In a paper-folding machine, the combination with its associated folding and buckling rolls and their coacting folding plates, of a transverse conveyor, adjustable advancing rolls adapted to be positioned for delivering the signatures thereto or for rendering said conveyor temporarily inoperative, substantially as set forth.
