MACHINE FOR TURNING DOWN THE EDGES or CLOTH OF'WEARING-APPAREL IN THE PROCESS OF MANUFACTURE.

Specification of Letters Patent.

Patented J nine 19, 1917.

' Application filed April 14, 1917. Serial No. 162,206.

To all whom it may concern:

Be it known that I, WILLIAM WILKIE, of 34 Garthland drive, Dennistoun, Glasgow, Scotland, engineer, have invented certain newand useful Improvements in Machines for Turning Down the Edges of Cloth of Wearing-Apparel in the Process of Manu-' facture, of which the following is a specification; v

This invention which relates to machines for turning over. and pressing down the edges of cloth of wearing apparel in the process of manufacture, has for its object to enlarge their scope by acting upon the rear and side portions of the cloth under treatment at one operation, increase their efliciency, vary their application and adaptation to the many parts of a garment or wearing apparel under treatment so that notonly'cuifs, collars and pockets and similar rectangular pieces which have hitherto been treated in machines for folding blanks of aforesaid parts,'but circular, oval and elliptical portions of cloth may be treated with similar good results. The invention consists of a machine of ordinary table height supported 011 legs, and upon the surface of the table, part of the mechanism is actuated and mounted. The two outer laterally movable infolders are invested with a backward and forward movement, and

with a long reoiprocating'infolder lying longitudinally across the machine, are designed to crease the side and rear edges of the cloth, the outer lateral infoldershaving also a transverse movement, and being carried by blocks on a horizontal rod or bar mounted on a slidable element which is moved by a pair of eccentrics or cams joined together by a long connecting rod. A

handlever is usedto turn the eccentrics or cams and is mounted 'on one of the eccentrics or cams. One or two central detachable dies which cooperate with the infolders pre viously mentioned are mounted on a hinged lever which is capable of being raised and swung back at will in order to insert into the machine the pieces of'clothto 'be'treated. That part of the table adapted to receive the cloth to be acted upon has its surface movable from beneath in order to exert pressure from beneath which is obtained by a trea'clle acting upon a ram or plunger. Heat is also applied. As with this class of machine, the rear and lateral infolders are broughtinto contact with the inner die or dies which are stationary during the creasing operation with the plates of the one overlapping the plates of the other and with the edges of the cloth interposed and acted upon between'them.

In order that my invention may be properly understood and readily carried into effect, I have hereunto appended one sheet of drawings,of which Figure 1 is aplan of the machine embodying my invention.

Fig. 2 is a front view, and

Fig. 3 is a cross section of the same taken on the line a, b, Fig. '1.

Fig. 4 is a section of part of the blocks and dies with the. cloth interposed therebetween.

Fig. 5 is a perspective View of the same with the dies and blocks separated from each'other, Fig. 6 is an alternative device for moving the reciprocating part of the machine, all hereafter more fully referred to and described.

Referring to the drawings, A is the table. A is the divided portionv thereof adapted to be heated and is designed to rise and fall by virtue of the forked arm A when operated by the treadle A B is the reciprocatingor slidable infolder part mounted on said table. C, D, are two eccentric disks mounted on the surface of the table at C D and connected by theconnecting rod D and operated by the hand lever- D for moving the said slidable part backward and for ward within the guide pieces E, F. B are slots in which the pins B fixed to the steel knife-edge plates X X may be adjusted and fixed with thumb screws. G, H are the infolders for carrying the infolder plates, and which infolders are carried upon the horizontal rod or bar Iwhich rod or bar I part B. The infolders G, H, while free to oscillate are kept from rising and made to resist the pressure of the raisable table A by the extended bent in portions G H in the turning down and pressing operation. 111 this connection it will be seen that parts G and H carry screws which are adjustable beneath the lower edge of a flange depending from the table A. However, it will be understood that these screws are not set up tight against the edge of the flange, since to do so would prevent the infolders from moving, but are merely set up close enough to prevent B from lifting when the ram A is forced up. These outer blocks carry the thin steel infolder plates X The dies P and Q are adjust-ably attachable to and detachable from depending plates T, U, by means of thumb screws, and by thumb screws P Q in open slots P Q? they adjustably support steel plates forming the central die or dies. This arrangement permits of various forms of dies being used. The said blocks G and H with the said knife edge plates X are adapted to move laterally in conjunction with the movement of the reciprocating part B due to the attachment of links K, L, pivoted to the blocks M and N which are carried on the horizontal rod or bar J mounted on the fixed part of the table and can be clamped thereto at any given point by means of the set screws M and N The lever O is hinged at O and is capable of being raised, and being locked in that position by the coaction of the levers O and 0 Fig. 3. Said lever carries the two central or inner dies or templets P, Q, and is provided with two arms R, S, pivoted at one end to the plates T, U, and the other end to a plate J which plate J is adjustably connected to the hinged lever 0; the plate W slides along the said hinged lever O and carries the rod V to which are attached the plates T, U, supporting the dies P and Q provided with knife edges or thin steel die plates X, and these, in conjunction with the outer infolders and the longitudinal infolder B having a knife edge or rear die' B are employed in the turning over and pressing down of the cloth and are actuated by hand, but in themselves do not essentially constitute the novel elements. It will be seen that the plate J can be adjustably moved along the lever O to adjust the central dies and fixed in position by the clamping screw J It will also be seen that a considerable lateral movement to and from the center of the machine is imparted to the dies due to the radiating of the arms R, S, and by fixing the plate J and moving the plate V7 forward, this movement may be utilized for freeing the central dies from the creased edges before pressing the creases in cases where it is necessary to move the central dies inward on tral lever O and hence perpendicular to the fixed rod J, and the movement of B causes the lateral movement of G and H, but the movement of G and H is perpendicular to that of B owing to the fact that the inclined arms'K and L are fixed to the bar J and the latter is fixed to the table A. Also, the infolders G and H move in opposite directions owing to the opposite inclinations of arms K and L, the infolders both moving outwardly or inwardly at a given time.

It is to be explained, that any suitable v shape of infolder plates may be fitted on to the infolders G, H, and the infolder plate B, and the dies P and Q. The infolders G and H are moved together by the links K and L- which are fixed to the adjustable blocks M and N and the dies P and Q, are moved when required by the arms R, and S, pivoted to the adjustable plate J and the plate W is capable of being moved along the hinged lever O to and from the plate J for adjusting the central dies, and the screw W is used to give the various adjustments when the knife edges B and X of the infolder B and infolders G and H are made to overlap with cooperating edges as is common to other analogous machines, the die plates X of the dies P and Q, with the cloth interposed between them and the edges X being shown in detail in Fig. 4 in order to illustrate the manner in which the cloth is folded.

Referring to Fig. 6, the mechanism for moving the reciprocating part of the machine consists of a quadrant and rack 2, the quadrant 1 being moved by a hand lever 3 mounted at one side of machine which communicates motion to the reciprocating part of the machine by the medium of a rack.
