Application filed February 14, 1908., Serial No. 415 .813.

To all whom. it may concern:

llo it known that l. Grzouon \V. SMITH, a citizen of t-hcl'nited States, residing at the city of ('ohoes. in the county of Albany and State of New York. have invented certain vnew and useful Improvements in Folding- Machines, of which the following is a specification.

.\l v inventionrclatcs to machines for-folding collar and unit blanks, and the objects of my invention are to construct a foldingover the edges of the die whilc'thc die remains within the fold. By removing the pressure from the foot pedal the infoldcrs luovc backward from over the die and the head of the press carrying the die will move upward from the bed of the press, leaving the operator the rt-ease of both hands for handling the gtxids. Other advantages will be disclosed hereafter. I accomplish these objects by means of the mechanism illustrated in the accompanying drawings, in which: f

Figure 1 is a plan view of my machine with the die head down, the die resting upon the bed plate. Fig. 2 is a frontelevation. Fig. 4 is a detail view of the wedge-shaped cam used to operate the infolders. Fig. 5 is a detail view of a modified form of Fig. 4. Fig. 6 is a section of the bed and intolders along .the line X-X- on Fig. 1. Fig. 7 is a detail of the lever and tchgiscoping rod used to raise the bed. Figs. 8 and t) are detail views of the diehcad and die. Fig. 1 is a detail of a modified form of die. Fig. 11 is a diagram showing the manner in which the successive operations are performed by means of my machine. l ig. 12 is a detail view showing the manner of operating the infoldcrs.

Similar numerals refer to similar-parts throughout the several views. r

In the manufacture of cuffs and collars, the blanks from which they are made are placed upon the heated bed or support of a folding machine. The die or former of the shape (lOFlltCl is then pressed down upon the blank and infolders fold the edges of the blank over the die. while the blank is upon the heated support and press the folds either lmfore or after the withdrawal of the die, thus making smooth edges of the goods, ready to be sewed or stitched audit) the shape desired.

ltctcrriug to the drawings, 2 is the frame,

of the machine and is mounted upon the supplemental frame 3. or upon any sultable support. The frame, 2, has pro ecting Iromthe back side thereof the arms, 1, 4. which contain the bearings for the rocking shaft, 5, to wlnch the arms, 6, 6, of the die head, 7, are

attached. To the shaft, 5, is also attached the crank arm, 8.

The top of the frame, 2, has an opening in the center adaptedto receive the bed plate,10. The normal position of the face of thebed platebcing flush with the surface, 9, of the frame 2. This bed plate, 10, is vertically movable as hereafter described.

Attached to the under side of the bed plate, 10. is a box, 14. in which are placed suitable resistance coils for generating heat by electricity. '1. he bed plate, 10, forms the top of the box, so that it is readily heated by the heat generated in the coils.

The portions of the infolders lying over the box ll, are.heated by being in contact with the bud plate, 10, or may be heated by means of perforations through the bed l'atc,

allowing' the heated air to pass upwar and come in direct Contact with the infolders.

The under sides of the infolders, 12, have hollow spaces, 15, adapted to receive suitable electric heating means. The heating means being for the purpose of heating-the portions of the infolders which do not lie over the box, 14, thus providing for the heating of the 'cntire infoldcrs.

- livotcd in the supplemental frame, 3, at i 17 is the foot lever 18, having a pedal portion, 19. Attached to the lever, 18, at 20 are the telescoping rods, 21 and 22, connecting the foot lever 18 to the levels 35. The 16-. vers, 35, being pivoted in the frame, 2, at 36 and 37, and adapted to exert an upward pressure n am the bed plate 10. At point 23 is attached the rod, 24. The up or end of the rod. 24, is attached to the we ge shaped .cam, 25 (Figs. 2 and 3) mounted on the front side of the frame, 2.

No. (366,766 issued to John Maitland and \Valter John Beattie, January 29th 1901, this invention being intended as an improvement to the machine shown and described in saidpatent. v

Attached to the foot lever, at 31, is the rod, 32, arranged so as to telescope into the spring case, 33, against the pressure of the spring, 34. The spring case, 33,bein at tached to the crank arm, 8, on the roe ring I shaft, Y

()n the face, 9, of the frame, 2, are securely fastened the bracing arms, 40, 11 and 42, adapted to resist any upward motion of the infolders, 12, 12, while allowing them free lateral movement. I I

The die, 13 is non-collapsible. It consists of a thin sheet of flexible steel, preferably about eight mills thick, attached to a suitable head. 7. The die may be made in sections for increasing the length to correspondwith thesize of the collar or cult which it is desired to produce. die and head of this type is illustrated in Figs. 8 and 9. ()r a different die may be used foreaeh size or style of collar or end, as desired.

Fig. 10 illustrates a modification of the die, 13, the steel sheet being hinged at some flexible spring to return the loose end to a -horizontal position, the-hinge being so constructed as to allow the end to bend downward but not upward. Tlieabove described dies permit the removal of the folded blanks withoutappreciable disturbance of the fold or crease.

The operation of .my collar and 'cufi turner is as follows: The goods come to the machine thoroughly damped, the operator 1 places the blanks upon the bed, then presses l with his foot upon the pedal, 19. This turns the foot lever, 18, upon its pivot, 17, and forces upward the rod, 32, against the spring, 31, in the spring case, Thus the spring, 34, forces upward the crank arm on the rocking shaft, 5, causing the die head, 7, to rotate about its pivotal bearings, 4, 4, and bring Referrin to Fig. 11, the pedal, foot lever, the head ant wedge shapedthe die, 13, into contact with the blanks on the bed, 10. A further motion sition of the cam before pressure is exerted on the pedal isiiidicated by dotted hues and marked 1st,- 5

It will be seen that in this position the head v is clear of the bed and ample space is provided for'the operator to insert tbe'blanks to be folded. The blanks are placed in the machine in the usual manner The operator then presses down with his foot upon the pedal, 19, moving it in rapid successionfrom 1st to 2nd then to 3rd 11 nd to pressure.

- As shown in the drawing when the pedal reaches the position marked Second the die. head by the action ofthe crank shaft, 8,

spring, 34, rod, 32 and foot lever, 18, has

been forced into contact with the work upon the. bed, 10. This motion of the pedal, 19, and footlever, 18, has caused the wedge shaped cam, 25, to be drawn down until the I cam is just starting to act. The movement of the pedalfrom 2nd to 3rd causes the cam to force the connecting rods, 26 and 27, to

the crank shafts 30 to turn and force the infolders inward folding the goods over the edge of the die. Further downward motion of the pedal will bring the head, 50, of the telescoping rods, 21 and 22, to come in con-.

move outward. These rods in turn causing be applied to the infoldcrs. This being rep sisted' by the bracing arms, 40, 41 and 42 an enormous pressure upon thefold is obtained.

For the purpose of returning the parts to the original or. 1st position I arrange the If I use the modified form'of cam springs, .to withdraw the infolders and distance fronr-one end and provided with a p 4 \Vhat I claim as my invention and desire to secure by Letters Patent is: 4
