FOLDING-MACHINE.

To all whom fit may concern:

Be it known that I, GAI-:RY J. DORMANDY, a citizen of the United States, residing in Troy, county of Rensselaer', and State of N ew York, have invented certain new and useful Improvements in Folding-Machines,

vof which the following is a specilication.

My invention relates to machines for inturning or in-folding the edges of blanks for cuffs, collars, or like articles; and more particularly to mechanism and parts for effecting the folding' and pressing of the folds of blanks that constitute the two parts of a cuff or analogous article preparatory to sewing said part-s together.

One of the principal objects of my invention is to produce a machine that will alford a more simple construction and operation, and it contemplates such arrangement of the fold-defining, infolding and pressing mechanisms that the part or member which lls the office of a fold-defining instrumentality shall serve the further purpose of bringing about a suitably powerful creasing pressure on the folds of the blanks.

@ther objects will appear during the description hereinafter following.

I will first describe a folding machine embodying my invention and then point out the novel features in the claims.

Figure l is a top view of a folding machine embodying the invention of the present application. Fig. 2 is a top view of a convenient form of expanding and contracting die or templet for use in the machine illustrated in F ig. l. Eig. 3 is a transverse section of the die or templet illustrated in Fig. 9. and taken on the plane of the dotted line mrt-m3 of Eig. l. E ig. 4C is an enlarged section of a detail of the die or templet. Fig. 5 is a longitudinal section of the die or templet of Fig. 2 and a portion of the bedplate of the machine, taken on the line of Fig. 3. E ig. 6 is a transverse section similar to that of Fig. 3, showing the pressure treadle and its connection, the parts being in that stage of operation in which the pressure is applied to the folds of the blank.

Similar letters of reference are employed to designate corresponding parts in the several figures of the drawings.

rThe bed and iii-folding mechanism of themselves are of a well-known type illus- Specification of Letters Patent.

trated in several prior patents granted to me, and therefore need not be described in very great detail.

A designates the bed of a folding machine embodying my invention, which bed is intended to serve as a support for the blanks to be infolded in said machine.

The folding mechanisln comprises a series of infolders B B B, fitted to move inwardly and outwardly with respect to the blanks on the bed of the machine, by any suitable means such as slideways C which may be integral with or adjustable upon the bed, as may be determined by the particular use to which the machine is to be applied.

For operating the infolders to effect their inward and outward movements, is shown an oscillating ring D having a handle CZ which is convenient for actuating the same when the machine is not operated by power. Intermediate of the oscillating ring D and the infolders B are a corresponding series of cams, comprising in the present instance, cam plates o, the eccentric cam slots of which are preferably arranged in such manner that upon a continued movement of the oscillating ring in one direction, the infolders B B B will be caused to operate successively in order of time, this being a well-known means for in-folding of blanks in what has come to be known as a locked corner blank.77 The infolders B comprise, as usual, heavy or stock portions and the plate or blade portions b, which latter, during the inward movements of the infolders, are adapted to engage with those edge portions of the blanks which extend beyond the templet or fold-delining member, to carry such edge portions of the blanks over the edge portions of the templet in the well-known manner. Such iii-folding blades will also preferably be fitted to be capable of a suiicient extent of upward and downward movement relatively to the bed of the machine, in order that the folds of the blanks formed by, and which rest upon the bed beneath, the infolders, may

be pressed between the infolders and the bed, through the application of a suitably powerful creasing pressure or force applied to the iii-folding blades, whereby such folds may be firmly fixed. This fixing or creasing of the folds of the blank has become practically a necessity in the present advanced stage of perfection in the art of cuff and collar manufacturing, and it is necessary in order to secure the most accurate results; and it has further been found very desirable to effect the pressing or creasing of the folds of the blanks after the removal of the edges of the templet or fold-defining member from such folds, but before the infolders are moved outwardly or away from such folds, thus avoiding the possibility of a disturbance or reopening of the fold owing to the outward movement of the folders before the creasing is effected. To further increase the efficiency of the creasing or pressing operation, I have illustrated the now well-'known feature of heating the bed of the machine as by means of steam admitted to the hollow chamber formed in the bed beneath its central portion, a steam pipe a being illustrated as a means of conveying the steam to the hollow chamber of the bed.

I will now describe a die or templet which is new not only in combination with the infolding and blank supporting instrumentalities already described, but is in itself radically new. The die illustrated in the drawings annexed hereto is of the so-called expanding and contracting type more commonly known as a collapsible die. rIhe said die is mounted at the end of a swinging arm E which by reason of pivots or hinges e at the rear of the machine, constitutes a convenient means whereby the die or templet may be elevated above the bed, or lowered to bring it in contact with the blanks upon the bed, and the arm E may be conveniently provided with a counterweight E to facilitate the elevation of the die. At the outer end of the swinging arm E is mounted the part F which is conveniently arched and to which the die proper is connected. The die proper consists of the stock portion G be neath which are movably mounted, by means of downwardly extending hangers L, the die or templet plates or blades H. The hangers 7L being connected to the stock portion Gr through suitable guiding means such as diagonal slideways, are connected to receive inward and outward movements in such slideways through an operating handle J which extends forwardly from the die or templet to a position where it may be easily grasped by the operator and oscillated from side to side to effect the expanding and collapsing of the die or templet. A convenient connecting mechanism is the following: A longitudinally movable cam plate K, fitted to slide in reverse directions upon the stock G, is provided with cam slots which engage with pins 7c that extend upwardly from the hangers 7L. Links j connecting the operating arm J with the cam plate K serve, when the V operating handle is oscillated, to transmit a to-and-fro motion to the cam plates K, which thereby operate upon the cam pins 7c to effect l with the folding operation.

the inward and outward movement ofthe hangers it upon which the die plates H are mounted.

The mechanism already described would be sufficient for the mere iii-folding of cuff blanks if it were not desired to press the same upon the bed of the machine before re` moving therefrom. If it were attempted to collapse the die by means of the handle J after the folds of the blanks were turned inwardly over the edge portions of the die, and thereafter to expand the die plates to their normal or outward position and bring them downwardly upon the infolders, it would be found that owing to the necessary thinness 8 of the die plates H and their resultant f1exibility, a suitably powerful creasing pressure could not be brought to bear upon the folds of the blank beneath the infolders through the instrumentality of the die. Practice has 8 shown that a very heavy creasing pressure is necessary to produce an effective fixing of the folds of a blank, and for ordinary work about one ton pressure is considered to be the smallest desirable pressure. In order to 9 make the die or templet of the present machine operative as a combined die and press` ing device, e. to make it adaptable to the transmission of such high pressure to the in` folders resting upon the folds of the blanks, 9 I have provided means whereby it is possible to temporarily strengthen or back up the said thin edge portions of the die plates after the completion of the folding act and during the application of powerful downl ward pressure to the die. The specific means illustrated in the drawings for effecting this strengthening orbacking up of the thin edge plates comprises the movable or removable braces M, of which there should be one or l more for each of the expanding and contracting plates of the die or templet, and which movable braces are mounted through a sliding rod m to move inwardly and outwardly independently of the hangers It. rl`his movement is preferably in a horizontal direction and is controlled by a spring M whose tendency is to force the said braces to their outward or operative position. Inas` much as such braces would, while in an outl ward position, interfere with the in-folding operation of the infolders B, I have provided a bar or pusher N whose function is to engage with a part of the infolder during the inward movement of the latter, whereby theA l infolder may automatically canse the brace M to move out of the way, or to its inward position. At the left-hand side of F ig. 3 is shown the brace M in its outward position before having been engaged by the infolder B, and in suoli figure it is apparent that the said brace is in such position as to interfere 0n the righthand side of Fig. 3 the infolder is shown as having engaged with the pusher iT and to l have forced the brace M to its inward posi tion out of the way. A spring ln, acting upon the pusher N tends to keep the same in a .horizontal position, a hinge a being pro` vided to permit an upward swinging of the pusher, for a purpose that will appear hereinafter.

In order to effect a suitably powerful downward force upon the die or templet, a treadle may be employed, as a suitable power-applying member. P represents such a treadle, and p, p', Q represent suitable link and leverage connections between the treadle IJ and the templet-carrying arm E. The link Q is preferably a hooked member adapted to engage a complementary projection upon the arm E, and a fixed roller g adapted to engage an inclined surface on the rear of the link Q serves as a means of effecting an operative connection between the' parts Q and E when the treadle is lowered, the same becoming disengaged when the treadle is again released, so that the templet-carrying arm E may be elevated. A spring g may be employed to press the link Q toward the roller g to insure a disengagement of the parts Q and E.

The operation of the machine heretofore described may be as follows: The operator places one or more thicknesses of material constituting a blank upon the bed of the machine in a position in which the plates of the expanded die or templet may be brought into contact with the blanks, the edge portions of the die plates resting directly upon the blanks upon the bed and within edge portions of the blank. At this initial stage of the operation the infolders will be in their outward position, as shown at the left in Fig. 3. I-Iaving brought the expanded die into contact with the blanks, the operator then, by means of the handle (Z, effects the inward movement of the several infolders, with the result of inturning the extending edges of the blanks over the edge portions of the die plates at the same time forcing inwardly the temporary braces M (shown at the right of Fig. 3). The next step will be to contract the die or templet so as to withdraw the plates thereof from within the folds of the blank. After this, the die or templet should be elevated, which permits the temporary braces M to snap back to their outward or operative position. The operator then again lowers the die or templet until the blades thereof rest upon the infolders, which latter are now in their inward position. This stage of operation is illustrated in Fig. (3, where the purpose of the hinges n and springs 'n will be obvious. Finally, 'the operator pressing the treadle, causes the engagement of the link Q with the templet--carrying arm E, as already explained, a further movement of the treadle P effecting a downward pressure upon the templet-carrying arm,

which serves to transmit to the die, and through the infolder to the folds of the blanks, an effective creasing pressure. After this, the operator releases the treadle, elevates the die, moves the infolders outwardly again, when the blanks may be removed from the bed, the machine then being in readiness for a second operation.

Obviously some features of my invention may be used without others, and the invention may be embodied in widely varying forms; therefore,
