Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed June 8, 1904. Serial No. 211,610.

To all whom it may concern:

Be it known that I, GARRY J. DORMANDY, a citizen of the United States, residing in Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Folcling-ldachines, of which the following is a specification.

My invention relates to machines for in turning or infolding the edges of blanks for cuffs, collars or like articles; and more particularly to mechanisms and parts for effecting the folding and pressing of the folds of blanks intended to constitute the two parts of a culf or analogous article preparatory to sewing such parts together.

One of the principal objects of my invention is to produce a machine that Will afford a greater range of operation and avallabihty as regards the character of the work to be done, and in simplifying such mechanisms and the means of adjusting and altering the same for various styles of blanks to be infolded, or for forming the various kinds of folds which may be produced upon such blanks.

Another object is to produce a machine capable of certain special classes of work, which it has heretofore been impracticable to accomplish upon a single machine.

Other objects will appear during the description hereinafter followed.

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

Figure 1 is a top view of a folding ma chine embodying my invention showing the parts in their initial position ready for operation upon a cuff blank having four square corners; Fig. 2 is a plan view of the machine shown in Fig. 1 with the die or templet and the pressure producing parts omitted; the mechanisms being in an advanced stage of operation; Fig. 3 is a plan view of one of the infolder blades or plates; Fig. 4; is a bottom view of one of the side infolder slides to which the infolder blade of Fig. 3 is adapted to be slidably connected; Fig. 5 is a plan view of a pair of end infolder slides; Figs. (3 and 7 are plan views of adjusting blocks by means of which the various in- :tolders may be adjustably connected to the infolder actuating mechanism; Fig. 8 is a plan view of a modification of my invention which shows the same principles as applied to the infolding of blanks for cutl's having two square and two rounded corners commonly termed half-round; the parts being shown in an advanced stage of operation, at which part of the blank will have been folded in actual use; Fig. 5) is a plan view of a further modification showing how the machine of Figs. 1 and 8 may be adapted to the infolding of cuffs having all four corners rounded, ordinarily termed an all-round or full-round cuff; Fig. 10 illustrates a folded blank as produced by the machine of Fig. 1; Fig. 11 shows such blank after its infolding has commenced, but before completion thereof, this being the condition in which the blank will exist when the infolders have arrived at the stage of operation illustrated in Fig. 2; Fig. 12 illust'ates a half-round cuff blank which has been partly turned on a machine such as illustrated in Fig. 8, before the completion of the infolding operation.

-Similar characters of reference are em ployed to designate corresponding parts in the several figures of the drawings.

The present invention relates principally to the radically new construction and arrangement of the parts comprised in the folding mechanism, and the combination thereof with the blank-supporting member or bed, the blank-defining member or templet and the pressing mechanism, all of which may be of any well known or approved form.

The drawings herewith illustrate what I consider to be the most approved forms of bed, templet and pressing mechanism as adapted to cooperate with the novel infolding mechanism hereinafter to be fully described.

The support in the present machine upon which the blanks may rest during the operations 'to be performed upon them may be of the circular form illustrated in several prior patents granted to me. Such bed is illustrated by the designating numeral 1.

The die employed in the present machine is of the well known expanding and contracting variety, commonly called a collapsible die and as illustrated in Fig. 1, it will be seen to comprise an operating handle A, which is suitably connected to a templet stock a and in a well known manner operatively connected, as by means of links, with to-and-fro moving cam plates A, which in turn have cam connections with the members which carry the die plates proper, the latter being so mounted as to be movable inwardly and outwardly, preferably in a diagonal direction. With such an arrangement an oscillation of handle A, whether by hand or whether power-operated, will effect outward and inward movements of the die plates so as to expand and contract the templet as a whole. The purpose ofso expanding and contracting the templet is in order that the plates thereof, which serve to define the blades of the blanks, may be withdrawn from such folds after their formation in order to permit a proper pressing of such folds. Therefore, I do not wish to limit myself to a contracting and expanding templet, since any templet which is capable of withdrawing from the folds of the blanks is within the contemplation of my invention; and in certain cases it might be desirable to employ a die or templet which is not intended to be withdrawn from the folds of the blanks before the latter are removed.

Any ordinary means for supporting the templet so as to be capable of being elevated from and accurately positioned upon the blanks upon the support may be employed, such as a swinging arm carrying the templet at its forward end and pivoted in bearings 64, a, at the rear of the machine. I have shown such arm broken away to betterillustrate the infolding mechanism in Fig. 1.

A convenient pressing mechanismis that illustrated in Fig. 1, as comprising parts or bars 14 which extend over all of the infolders when the latter are in their inward position; the said pressure bars being connected in suitable manner as by means of pressure rods 18, which may pass through the bed of the machine, toa treadle or other power applying means, the treadle being a well known and convenient power applying means when the machine is not operated by power.

An oscillating or to-and-fro moving member or ring 2 is employed as an infolder actuating means. Other means may obviously be employed, but a great advantage lies in the use of the oscillating ring, inasmuch as it permits the adjustment or replacement of the cam or other members which serve to transmit the oscillating motion of the ring to the infolders; and further permits all of such members to be actuated in unison. A handle 2 is illustrated as a convenient means to oscillate the ring 2 when the same is to be done by hand.

For the formation of the blank illustrated in Figs. 1 and 10 are employed four infolder plates, each one of them having the form of an L, as will be more clear from Fig. 3, the two arms of the L extending respectively along the side and along the end of the blank from each corner thereof. The branches of each infolder plate are represented by the numerals 20 and 18 respectively. Heretofore, such L-shaped infolders have sometimes been fitted to receive a diagonal movement inwardly andoutwardly, which would obviously result in causing a bunching of the material on the blank carried over the corner of the die or templet in such diagonal movement, forming what is known as a crush corner. In order to form a so called locked corner, various means have been devised, one of which is the provision in such infold'ers of a slot which is arranged in alinement with one or the other of the inner edges of the plate, as clearly shown in Figs. 1 and 3, together with means for causing the infolder to be moved inwardly, first in a direction substantially parallel with the said slot, this forming a fold along one of the adjacentsides of the blank, the extending edge of the fold passing into the said slot; and a subsequent inward movement of the infolder in a direction at an angle to its former movement, serving to infold the other adjacent edge of the blank and the extending edge of the fold already formed. This particular device I do not, in the present application, claim as new, inasmuch as I have referred to it in a prior pending application. For effecting the inward movements of the L-shaped infolder plates in two directions successively, I have illustrated the following novel means: For each infolder plate there are provided two slides which are guided in directions at an angle to each other, preferably a right angle, as shown in Figs. 1 and 2. Referring for convenience to Fig. 2 and taking the lower left-hand infolder plate, the two arms of which are marked 18 and 20 respectively, the operating mechanism therefor will be seen to consist in the forwardly extending slide 4, which is guided to move toward and from the operator, and the laterally extend ing slide 5 which is guided to move to the left and right. The infolder plate is not rigidly connected to either of the operating slides 4 or 5, but is movably connected with both of them in such manner that by giving proper extent and speed of inward and outward movement to the respective slides, any manner of inward and return movements may be communicated to the infolder blade.

A convenient mode of movably connecting the infolder blade with its two actuating slides is by providing a sliding connection between the infolder blade and one of the slides and a slotted connection between the infolder blade and the other slide. Thus the slide 4 is shown to be provided with a groove or a slideqvay 9 which is preferably parallel to the edge of the infolder blade and is adapted to engage with a tongue 8 formed upon the branch 20 of the infolder blade.

lVith such arrangement it is obvious that forward and backward movements of the slide 1 will effect outward and inward movements, relative to the blank, of the branch 20 of the infolder blade, at the same time leaving the infolder blade free to be moved in a direction at right angles to the movement of slide 4:. Instead of providing a similar connection between the branch 18 of the infolder blade and the slide 5 it is sufficient to simply provide a slotted connection, preferably by forming a slot 7 in the slide 5 to engage a roller stud 6 upon the infolder blade. By this means inward and outward movements of the slide 5 may effect inward and outward movements of the branch 18 of the infolder blade relatively to the blank, independently of the movement of the infolder blade effected through the slide at, as already described. The remaining four infolder blades are shown as being constructed and fitted in precisely analogous manner, the description of which it is unnecessary to repeat. The slides 4t, 4t, 5 and are preferably of an L form, as shown in Figs. 1, 4- and 5, in order to better carry out the purposes described. The guiding means for the slides 4, at, 5 and 5 may conveniently be analogous to that shown in my said prior patents, and consists in slide-ways formed by means of members 3, 3, which may be attached to the bed of the machine in an adjustable or replaceable, or other suitable manner.

As a special improvement, and one which is permitted by the already described arrangement of infolder operating slides, I have shown each slideway constructed large enough to contain the slides 1 and 5, or the slides 1 and 5 of two adjacent infolders. This forms a more simple construction, dispensing with otherwise necessary parts; permits the two slides to be operated through a single cam, as will hereinafter appear; and further permits the use of an inter-connection through which the two slides within the single slideway may be secured to each other to form in effect a single slide for certain purposes.

10 and 16 represent adjusting blocks, each one of which may be adjustably attached to one of the pair of slides mounted in each slideway. These adjusting blocks are pro vided with slots 18, by which they are adapted to be secured by bolts 15 to the slides 1 and 5 respectively. The adjusting blocks are each provided with a downwardly extending pin 11 which may or may not be provided with a roller and which is adapted to pass through slots provided in the slides 4 and 5 for that purpose (see Fig. 5) and to engage with cam slots 12 formed in the oscillating ring 2 er in cam plates removably attached thereto. The infolder actuating cams 12 are so formed, as illustrated in Figs. 1 and 2, that the cam pins 11, 11, corresponding to the slides 1, 5, respectively, are in initial position engaged with a concentric or inoperative portion of the cam; this concentric portion being succeeded by an eccentric portion serving to carry in succession the two pins ll, 11, inwardly; and thereafter a second concentric portion.

Sometimes it is desirable to produce a blank by the method which I have conceived and illustrated in Figs. 10 and 11, namely by folding one end portion of each edge of the blank in alternation, and subsequently folding the other end portion of each edge of the blank, and with it the overlapping portion of the fold already formed. This results in the blank of Fig. 10, whose con struction is such that any two blanks may be interlocked in a simple and obvious manner, and with either end of one blank engaging either end of the other. This result is easily effected in the machine of Figs. 1 and 2 by providing the cams 12 all of identical construction. Fig. 2 shows such cams as having operated upon one of each pair of cam pins and the slides 5, 5, 5 and 5 connected there-- with, at which stage each of the L-shaped infolder blades is moved inwardly in only one direction and the blank at such stage having assumed the form illustrated in Fig. 11. A continued movement of the oscillating ring 2 (which of course may be continuous from the initial movement until the infolding is complete) serves to force inwardly the re maining slides a, 4, at and at to complete the infolding of the blank.

The operation of the machine of Figs. 1 and 2 as above described may be as follows: The operator places one or more thicknesses of material constituting a blank upon the bed of the machine in the position in which the plates of the expanded die or templet may be brought into contact with the blank, the edge portions of the die plates resting directly upon the blanks upon the bed or support and within edge portions of the blanks. At this initial stage of the operation, the infolders will be in their outward position, as shown in Fig. 1. Having brought the expanded die into contact with the blanks the operator then, by means of the handle, moves the oscillating rin 2 in the direction of the hands of a watch. The first effect of this is through the cam pins 11 to force inwardly the slides 5, 5, 5 and 5, which partly completes the infolding of the cult blank; and the continued movement of the oscillating ring elfects the inward movement of the remaining slides a, 4-, 1 and 41, thus completing the infolding. The next step will be to withdraw the plates of the die from within the folds of the blank and then to bring into operation the pressing mechanism to squeeze the folds and thereby fix them with a sharp crease, which may be assisted by suitably heating the bed of the machine. The die may now be elevated, if it has not already been elevated, and the infolders may be moved outwardly by the return oscillation of the ring 2, the blank removed, and the machine is then in readiness for a new operation.

Vith the modifications of Figs. 8 and 9, where rounded corners are shown, there is no possibility of producing four locked corners, inasmuch as the rounded corners are preferably formed by crushing or forcing in diagonally the extending edges of the blanks. Therefore a modified operation is necessary.

The machine of Fig. 8 may be constructed simply by removing two of the infolder blades of the machine of Fig. l and substituting blades of rounded form and then re-adjusting the infolder operating mechanism as follows: In order to effect diagonal movements in the infolder blades corresponding to the two rounded corners of the cuff, it is only necessary to disconnect or remove two of the adjusting blocks 16, for example those at the left hand and rearward sides of the machine. This breaks the cam connection between the corresponding slides 4, 4 and the oscillating ring. The purpose of the off-set of the adjusting blocks 10 (Figs. 1, 2, 7 and 8) will now be apparent. The adjusting screws 15, which formerly connected slides 4:, P to the adjusting blocks 16, 16, are now employed to rigidly connect the adjusting blocks 10., 10 to said slides 4c, 4, as clearly shown in Fig. 8, whereby the slides 4 and 5-at the rear of the machine are rigidly connected so that they will move inwardly in unison, and the same is true of the slides 4 and 5 at the left. The modified operation of such machine will be as follows: On the initial movement of the oscillating ring not only will all the slides 5, 5, 5 and 5 be moved inwardly (as described in connection with the machine of Fig. 1), but also will the slide l, at the rear of the machine, and the slide 46 at the left,be moved inwardly, the resultant action upon the two rounded infolder blades 20 being a diagonal movement. This stage of operation is represented in Fi 8 and the condition that the cuff blank will assume at this stage is illustrated in Fig. 12. The continued movement of the oscillating ring will serve to carry in the remaining slides a and 4 to complete the infolding. This forms a locked-corner halfround cuff blank of advantageous construction and such that any two blanks may be interlocked without the necessity of employing two machines, or of re-adjusting a machine to produce the complementary portions of the cuff.

The modification shown in Fig. 9 consists in making the same change in the form of infolder blade as that described in connection with Fig. 8, upon all four corners, whereby the so-called full-round cuff is produced. Vith this arrangement it is preferable to remove all of the adjusting blocks 16 and to connect all of the adjusting blocks 10 with the corresponding slides 4t and a, whereby all of the infolder blades will be adapted to receive diagonal inward and outward movements, as already described in connection with Fig. 8.

The formation of the oscillating ring 2 and the cams secured therein is such as to render the latter adjustable relatively to the ring. The curvature of the cams corresponds with the curvature of the ring, and the cams can be set at any point desired or can be detached and replaced. VVhen screws such as those shown in Fig. 1 are employed for securing the cams in place on the ring, the adjustment can be secured by forming a new threaded hole in the ring for each position of the screws, or the adjustment may be accon'iplished as has been set forth in previous patents granted to me. I refer particularly to Letters Patent 714,787, granted Dec. 2, 1902.
