FOLDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 611,070,6.ated September 20, 1898. Application led December 30, 1897. Serial No. 664.695. (N0 model-i To all whom tm/Cty concern:

Beit known that I, MARTIN J. LOCKE, a citizen of the United States, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Folding-Machines, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings and the letters 0f reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure l of the drawings is a top plan View of my improved folding-machine with the templet or former expanded and resting upon the bed-plate with the folders'distended or open. Fig. 2 is a bottom plan View of the same. Fig. 3 is a top plan View of the bedplate with the former and three of the folder plates detached. Fig. 4 is a front elevation of the machine with the former removed from the bed-plate. Fig. 5 is a vertical cross-section taken on the broken line 5 5 in Fig. 1. Fig. 6 is a vertical section taken on the broken line 6 6 in Fig. l. Fig. 7 is a vertical section taken on the broken line 7 7 in Fig. l. Fig. 8 is a bottom plan view of one of the folders. Figs. 9 and 10 are plan views, respectively, of a blank before and after its edges have been folded by my improved machine. Fig. 1l is a top plan view showing the corners of a movable folderplate and formerplate with the guide-linger in position fol` folding the corner of a cuff-blank shown interposed between the plate-corners and resting on the bed-plate or the machine, both the former and folder plates being in an open or distended position. Fig. 12 shows vthe relative position of the parts after the folderplates of the machine have been closedor moved over the former-plates.

My invention relates to that class of machines in which a collapsible shaper or former movable to and from a blank-supporting bed is superposed upon a bed-supported collar or cuff blank, while inwardly and outwardly movable folder-plates are moved inwardly to fold the edges of the blank over the edges of the former.

The object of my invention is to provide collar and cuff blanks with uniformly-dis posed corner-folds which are interlockable the folds of one blank with those of another, as will be hereinafter more fully explained.

My invention consists of mechanism for regulating the laying of the corner-folds of acollar or cuff blank, whereby a certain predetermined one of the two sides forming a corner of the blank is first folded over and its corner-fold laid upon the former or shaper and the other side afterward folded and its corner-fold laid upon the corner-fold of the first-turned side.

In the manufacture of collars and cus two blanks, one or both with one or more interlining plies, are separately folded by turning in the edges. The two folded blanks are then superposed one upon the other, with the folded-in edges concealed between the super-Y posed plies, after which the plies are all secured together bya line of stitching through the folded-in edges. It is quite important, therefore, that the corner-folds should be formed systematically, not only to secure the least number' of superposed thicknesses, but to produce a uniform fold that will always permit the corner-fold of eachy folded blankl to interlock with the corresponding cornerfold of every other blank, whereby the finished collars or cuffs composed of any two separately-folded blanks will present neatlyfolded corners of uniform thickness and form. Fig. 9 of the drawings shows an unfolded blank, and Fig. l0 a blank folded by my improved machine.

Referring to the drawings of the machine, A is the bed-plate, provided with supportinglegs A' and ears A2, containing the cone-bearings of the former A3, which former may be of any known class. I have shown a former collapsible on four sides by moving the cornerplates A4 inwardly. These corner-plates are secured to the central head by studs projecting up through slideways A and con nected by links A6 with a lever A7, having a handle A8, adapted to operate the lever to slide IDO the corner-plates and to swing the former to proper are made of sheet metal and fixed upon thicker castings B2, each having a channel on the lower side adapted to receive the slide- Way-rib on the bed.

As a means for sliding the folder-plates to and fro I provide a lever B3, fulcrumed at B4 upon the under side of the bed and provided with an operating-handle B5, which projects out through an opening in the front portion of the bed-frame. The lever B3 is connected at each end by links B6 with a pair of levers outside the bed-frame, one end with the levers B7 in front and the other end with the levers Bsin rear. Each of the levers B7 and B8 is fulorumed intermediately of its ends upon the bed-frame, as by screw B9. The short end of each lever is connected With a cornerfolder, so as to slide the same, as by pin B10, projecting from the corner-plates and loosely iittin g the open slot Blzin the several levers.

The dotted lines C in Fig. 3 represent the shape and size of that part of the machine called the former, which is also the shape and approximately the size of a nished cuff folded on the machine. I have also placed on this Fig. 3 broken lines C', drawn to bisect the respective corner-angles formed by the dotted lines C.

It Will be observed that each one of the slideways B is inclined to the line Which bisects the neighboring corner-angle and that all the slideways are similarly inclined With relation to their respective corners. The result of this inclination is that each cornerplate, when moved along its slideWay toward the blank, travels faster toivard one of the edges forming the neighboring corner of the blank than toward the other edgethat is, if the corner-plate shown in Fig. 3 is moved from the position shown by solid lines to that indicated by the dotted lines C2 the long arm t of the corner-forming plate will have traveled farther than the short arm c. It is also apparent that the short arm will cross the dotted line C in advance of the long arm. The short arm Would therefore be the first to lap the form er-plate and fold over upon it the corresponding edge of a cuff-blank interposed between the bed and former with its edges resting upon the folder-plates. The long arm afterward laps the other side of the corner and folds the corresponding edge of the blank over onto the former.

Starting from the corner-plate shown in Fig. 3 and passing around the bed-plate to the left, the next corner-plate has its slideway so inclined that its long arm will be nearer the edge of the former, and therefore will be the arm which has the comparatively slor movement, While on the next corner the short arm moves more slowly, like the one shown in Fig. 3, and on the fourth corner the long arm has the comparatively sloW movement, the alternating arms, Without reference to their lengths, having similar movements. All the slideivays being similarly inclined with relation to their respective corners, as before stated and shown, the respective arms of the corner-folders all travel in unison and produce like results, whereby each of the four edge folds of a folded culf has one end of its fold underfolded and the other end overfolded with relation to the respective edge folds of the neighboring edges of the cuff, as shown in Fig. 10, the object of such an arrangement being to lay the corner-folds, as shown in Fig. 10. I am able to facilitate uniformity of action by providing the short or slowly-moving arm of the corner-folder With a riser C3, which forms an upright or abutment in the same vertical plane with the face edge of the plate which holds the neighboring edge of the blank in a vertical position when the former is swung down onto the blank .I previously deposited upon the bed and edges of the folder-plates, as seen in Fig. G. Then as the folder laps the former the riser tends to keep the engaged edge of the blank smooth and under control until the folder-plate passes over it.

The operation may be still further facilitated by means of the finger-guide A10, Which holds back, as seen in Fig. 7, the extreme edge of the blank opposite the long arm of the folder as long as possible until the cornerfold (represented by the dotted line (lL in Fig. 10) has been partially formed and laid upon the former, after Which that edge is folded over and its corner-fold C5 laid over upon the edge of the blank folded over by the short arm.

In Figs. 1l and l2 I have shown a modified form of riser, which consists of a lever D, fulcrumed at one end by pin D to the folderplate and provided with an upright pin D2, adapted to be engaged by one end of the controllingspring D3, which has its coils D4 slipped onto pin D' and its other end bearing against the casting of the folder. Another lever D5 is fulcrumed at D upon the folderplate with one end in engagement with the lever D, as shown, and the other end engageable with the guide-iin ger A10, projecting from the former. As the folder-plate travels along its slideway toward the blank and former from the position shown in Fig. 11 the lever D5 engages the guide-iin ger at once and forces the riser-lever over the edge of the'former in advance of the short arm of the folder-plate,

so that the parts occupy the position shown inv Fig. l2 at the end of the folding movement of the folder-plate.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a machine for folding the edges of collar and cuff blanks, the combination with a bed for receiving and supporting the blank; and a former movable to and from the bed; of corner-folding plates movable inwardly and outwardly along the upper surface of the bed; slideways for the folder-plates severally and similarly inclined to the straight lines bisecting the corner-angles,respectively, whereby one arm of a corner-folding plate is movable to and from the blank more rapidly than the other; means for operating the former; and means for moving the cornerfolding plates inwardly and outwardly along the respective inclined slideways, substantially as described.

2. In a machine for folding the edges of collar and cu blanks; the combination with a bed for receiving and supporting the blank; and a former movable to and from the bed; of corner-folding plates movable inwardly and outwardly along the upper surface of the bed; slideways for the folder-plates severally and similarly inclined to the straight lines bisecting the corner-angles respectively, whereby one arm of a corner-folder plate is movable to and from the blank more rapidly than the other; a blank-en gagin g riser on the more slowly movable arm of the several foldingplates; means for operating the former; and means for moving the corner-folding plates inwardly and outwardly along the respective inclined slideways,substantially as described.

3. In a machine for folding the edges of collar and cuff blanks, the combination with a bed for receiving and supporting the blank; and a former movable to and from the bed; of corner-folding plates movable inwardly and outwardly along the upper surface of the bed; slideways for the folder-plates severally and similarly inclined to the straight lines bisectin g the corner-angles respectively, Whereby one arm of a corner-folding plate is movable to and from the blank more rapidly than the other; blank-engaging detaining-ingers,

severally projecting from the several corners of the former, whereby each fin ger projects, when the former rests upon a blank horizontally, over one edge of the blank and over the more rapidly moving arm of a cornerfoldingplate; meansforoperatingtheformer; and means for moving the corner-folding plates inwardly and outwardly along the respective inclined slideways, substantially as described.

4. In a machine for folding the edges of collar and cuff blanks having a bed, a collapsible former, and corner-folding plates, the combination with the folding-plates, of a riser on one arm of the folding-plates engageable with an edge' of the blank forming one side of a blank corner, and a detaining-inger on the former engageable with the edge of the blank forming the other side of such blank corner, and means for operating the former and folding plates, substantially as described.

5. In a machine for folding the edges of collar and cuff blanks, havinga bed, a collapsible former, and corner-folding plates, the combination with the folding-plates, of a movable riser pivoted upon one arm of the several folding-plates engageable with an edge of the blank, a riser-operating lever pivoted on the several folder-plates, and a detaining-finger on the several former corners engageable with an edge of the blank and with the riser-operating lever, whereby an inward movement of the angle-plate will cause the movable riser to move more rapidly than either arm of the plate, and means for operating the former and folding plates, substantially as described.

6. In a folding-machine, the combination with a two-armed corner-folder, and means for moving one arm more rapidly than the other, of a movable riser on the more slowly moving arm, and means for advancing the riser beyond the arm, substantially as described.

In testimony whereof I have hereunto set my hand this 15th day of September, 1897.
