A particular use of such indentatiojns on the Referring more particularly to the drawings, I blank is for assembling purposes. In assembling designates the die head with its forming die I0, collars, that is, in stitching the collar top to the which is carried by the arms Il fixed to a shaft blank, it is convenient to have on the blank I2 at the backof the machine, said shaft being indicia denoting where the ends of the top should supported by the machine frame.

By providing mechanism carried entirely In Figure 3 the forming die I0 is shown as comby the die head to indent the infolded blanks, it prising end sectionsv I4 and I6 and a central sec- 55 tion I5; rigidly carried respectively by forming die section carriers I1, I9 and I8. Forming die sections i 4 and I6 have in one edge thereof substantially semi-circular recesses 25 and 26, respectively, each adapted to cooperate, as shown in Figure 6, with one of a plurality of fingers 21, when the fingers are moved into the recesses in the manner hereinafter described, to indent and form indicating indentations or impressions on the folded edge of the blank. These impressions serve to denote the points on the blank where the ends of the collar top are to be attached.

The opposite edges of sections I 4 and I6 are provided with substantially semi-circular recesses 28 and respectively, each adapted to cooperate with a finger 21, when the fingers are moved into the recesses in a manner hereinafter described, to indent and form indicating indentations or impressions on the folded edge of the blank, these marks denoting the points of attachment of the blank carrying the top to the shirt collar band at the front opening seams.

Section i5 has in one of its edges a similar recess to cooperate with one of the fingers to form an indicating indentation in the folded edge of the blank of material at the center thereof.

The central section carrier I8 is fixedly mounted to an angle bar 3|, while as shown in Figures 3 and 5, section carrier I9 is adjustably carried by the angle bar 3|, the latter being rigidly secured to the top plate 32 by bolts 33. Carrier I9 may be adjusted longitudinally along angle bar 3| by means of bolts 34 passing through slots 35 in the angle bar, and threaded into spaced apertures 36 in carrier I9. This adjustment serves to regulate the length of the forming die for various collar sizes.

Carrier i1 is adjustably mounted on an angle bar 31 in the same manner as is carrier I9 to angle bar 3 I,` 1out angle bar 31 is movably attached to top plate 32 by means or" bolts 28 provided with washers 2i, said bolts passing through slots 22 in the top plate 32, and being threaded into apertures in angle bar 3?. This movement is longitudinal of the top plate 32, and is controlled by the pressure of spring 33, which extends between and is secured to angle bars 31 and 3|.

As shown in Figure 3, portions 39 and 40 of the inner end surfaces of angle bars 31 and 3|, respectively, are adapted to cooperate with a cam 41 to expand the forming die in a manner hereinafter described.

Referring to Figures 2 and 4, a bent arm 4| is pivoted on a pin 42 mounted in brackets 43 attached to an extension 44 of the working table I3; this arm is secured adjustably at its opposite and threaded end 45 to an angular extension 46 of the longitudinally tapered cam 41 by means of nuts 46; said threaded end passing through an aperture in the angular extension 46. The cam 41 has a tapered portion 41 (Fig. 4) which cooperates with surfaces 33 and 40 to move angle bar 31 carrying forming die section carrier I1 endwise away from angle bar 3i and forming die section carrier i8, to expand the forming die when the die head is being lowered. The retraction of cam 4i when the head is elevated permits spring 33 to return angle bar 31 toward angle bar 3| to contract the forming die. The action of cam 41 is timed to the action of the indenting fingers 21, as will be later explained. y

The die head top plate 32 is provided with a number of bearing lugs 49rto receive and support finger-carrying shafts 55 and 56. Collars 51 having set screws 58 are arranged inside said bearing lugs, as shown in Figure 4, in order to hold the shafts against longitudinal movement within the bearing lugs, the shafts being free to rotate within the bearings.

In Figure 5 the fingers 21 are shown attached to their carrying shafts, said fingers being substantially circular in cross section and tapered, and provided with outwardly bent portions 59 at their ends. The ngers project from fittings. 69 which include a hollow cylindrical portion 6| which embraces the shafts. 'Ihe fingers, or their supporting fittings, may be suitably recessed to receive an electric heating coil. The cylindrical portion 6I is split as at 62 and, on opposite sides of the split opening, is provided with lugs 63 and 64, said lugsbeing provided with screw threaded apertures to receive a set screw 65. By reason of this connection, each linger may be adjusted longitudinally along its finger carrying shaft to align it with its cooperating forming die blade recess before setting up on screw 65 to secure it in place. This longitudinal adjustment may be done by eye, or suitable indicia may be provided for this purpose on the finger shafts. It is desirable to have this adjustment to permit cooperation of the fingers with various sizes of forming die blades, or with forming ldie blades having recesses in different positions. Furthermore, the

fingers may be rotated around their carryingv shafts before tightening screw 65, in order to regulate the force with which the fingers impinge on the forming die blade in indenting, or to adapt the fingers for use with forming die blades of various contours.

The finger carrying shafts 55 and 56 are rotated through suitable mechanism. from rock shaft I2, said shaft being rocked by a depending arm 66, which arm is moved by a cam |04 on the main cam shaft ID3 in a manner fully described' in my prior Letters Patent No. 1,698,469, granted- January 8, 1929. 1

As shown in Figure 2, an upwardly extending arm 61 is fixed to rock shaft I2. Arm 61 is provided approximately midway of its length with an aperture which forms a bearing for a crank shaft 68, said crank shaft being rotatable within the bearing. The outer end of a connecting rod 1| is pivotally connected toa crank 69 ofthe crank shaft 68. The inner end of the connecting rod 1| is pivotally connected to a crank 13 by a pin 12. The crank 13 is secured to finger carrying shaft 55 by means of a collar portion 14 and a set screw 15.

A stub shaft 89 is nxed to the extreme upper end of the arm 61, and rotatably mounted on the near end of this stub shaft (as viewed in Figure 2)', is a segmental gear 8| having teeth 82. The teeth 82 mesh with the teeth of a pinion 83 fixed to crank shaft 68. The segmental gear 8| is provided with a rearwardly extending arm 84 to which a link 86 is pivotally connected. The opposite end of link 86 is pivoted at81 to an upward projection 88 of the working table extension 44.

Referring to Figures 3 and 4, finger carrying shafts 55 and 56 carry movable split collars 89 and 90, respectively, said collars being held to their shafts by set screws 9| and 92, respectively. Collar 89 has integral therewith a downwardly extending crank arm 93, while collar 90 likewise carries an upwardly extending crank arm 94. Connecting the ends of said cranks, and pivoted thereto at its ends, is a link 95, said link with cranks 93 and 94 serving to rock shaft 56 in a direction o-pposite to the direction of rotation of shaft 55 in order to cause the sets of fingers on opposite sides of the die head to impinge on the forming dies simultaneously, as will be later described. I

The action of the edge indenting ngers 21 as the die head is lowered and elevated is revealed in Figure 2, wherein die head positions marked A, B and C are respectively the full elevated, intermediate, and completely lowered positions. The corresponding positions of the crank 69 which actuates connecting rod 1| are, respectively, A', B and C'. In full elevated position A, at which time the blank of material is placed in position on the bed 2, the crank 69 is at its lowermost position A', and fingers 21 will be completely withdrawn from the forming die. At this position the surface 41' of cam 41 will not be in engagement with surfaces 39 and 40 and the forming die will be contracted.

As depending arm 6B is moved to the right as viewed in Figure 2, shaft l2 is rocked counterclockwise, this movement serving to lower die head arms and to move arm 61 from right to left. Arm 61 will carry the segmental gear 8| from right to left, and by reason of extension 84 being pivoted to link 86, segmental gear 8| will also move around its shaft 88 in a clockwise direction. The rotation of segmental gear 8|, through its teeth 82, causes rotation of pinion 83 and shaft 68 in a counter-clockwise direction, moving crank 69 from position A' toward full line position B. This movement draws connecting rod 1| to the right, which rocks finger shaft 55 clockwise by means of crank 13, and the nger shaft 56 counter-clockwise through link 95; it will be apparent that such movements of the finger shafts cause the indenting fingers 21 to move into enga-gement with their corresponding forming die recesses.

During the movement described above, namely, from die head full elevated position A to intermediate position B, the tapered portion 41' of cam 41 has engaged surfaces 39 and 40 to completely expand the forming die at die head position B when the ngers 21 engage their recesses. There being no blank of material on the forming die at this time, no indenting is accomplished.

Further lowering of the die head causes further movement of segmental gear 8|, which in the same manner as above, brings the crank 69 to its highest position C', thus causing the indenting fingers to be completely retracted from the forming die when the latter reaches the bed, as shown by die head position C. The fingers bein g completely retracted, it is apparent that the infolders are free to move in and fold the edges of the blank of material over the forming die without interference from the fingers.

During the above movement of the die head, namely, from position B to position C, cam surface 41 remains completely engaged with surfaces 39 and 40, to keep the forming die completely expanded.

The blank is now infolded and pressed over the forming die, in a manner well known in the art, and after said operation, and in a manner fully described in my prior Patent No. 1,698,469, depending arm 66 is caused to move from right to left to turn rock shaft |2 in a clockwise direction and elevate the die head with its forming die, said forming die now carrying the blank of material infolded over its edges.

The rocking of shaft I2 in a clockwise direction moves arm 61 from left to right, thus carrying segmental gear 8| from left to right, and causing it to rotate around stub shaft in a counter-clockwise direction. Thus pinion 83 with crank shaft 68 is rotated clockwise to move crank 69 from upper 4position C toward intermediate position B', drawing link 1| to the right to rock finger carrying shaft 55 clockwise; and nger carrying shaft 56 counter-clockwise through link 95, the movements of the finger carrying shafts tending to move the fingers into their recesses in a direction in the plane of the forming die and blank. When the die head reaches the intermediate position B, it is apparent that the ngers will be forced into the forming die recesses, thus making an indentation on the edge of the blank which is folded over the edge of and carried by the forming die.

It is to be noted that, upon the die head reaching the intermediate position B on the upstroke of the die head, at which position the fingers are in engagement with their recesses, that cam surface 41' is still completely engaged with surfaces 39 and 48 to retain the forming die in expanded condition.

Movement of the die head from position B to position A will, of course, retract the fingers, and it is during this phase of the die head travel that cam surface 41' is removed from surfaces 39 and 40 to permit contraction of the forming die. The forming die being contracted, the attendant may easily strip the infolded, pressed andindented blank from the die.

As mentioned before, the fingers 21 may be adjusted longitudinally of their shafts for proper positioning with respect to their forming die recesses before operating the machine. This may be done most conveniently when the die head is elevated, and may be done by eye, or by means of suitable indicia on the finger oarryingnshafts 55 and 56. A suitable hand tool may be inserted between cam surfaces 39 and 40 when the die head is elevated, to expand the forming die toaid in adjustment. In Figures 3 and 4, the forming die is shown contracted as it would be in the full elevated position A, and the recesses 25 and 28 in forming die section I4 are shown disposed a slight distance inside the position of their respective fingers 21; this distance allowing for, and being equal to, the longitudinal distance traversed by forming die section |4 during expansion. Such positioning of fingers 21 with respect to recesses 25 and 28 insures alignment of said recesses with their respective fingers 21 when the forming die is expanded, it being in such condition at the intermediate die head position B, when the fingers engage the recesses to indent the folded edge of the blank.

In Figure 7, a linger construction is shown in which a finger 21 is shown held within the finger hitting 60 by means of a retaining screw |80. Fitting 60 is of hollow construction, having disposed within its hollow body an electric heating coil IUI. Referring particularly to Figure 8, a modification of finger and cooperating recess is shown in which a finger 21 substantially triangular in cross-section cooperates with a V- shaped recess in the edge of the forming die blade I8.

In Figure l, the mechanism for operating depending arm 66 to raise and lower the die head is disclosed, as well as the mechanism for operating the infolding dies 3, 3. This mechanism is described Vin my prior Letters Patent No. 1,698,469, granted January 8, 1929, to which reference is made for a complete description thereof. Figure 1 illustrates the mechanism employed in Patent No. 1,698,469, with the addition of means, which will be later described, to operate the additional infolding die 3.

A brief description will suifice to show the operation of said mechanism.

Shaft |03 is a cam shaft, which may be rotated from a source of power in either direction through suitable clutch mechanism. Mounted on said cam shaft is a cam |04, which, when rotated in a counter-clockwise direction, bears against a cam follower roller |05 carried by a pair of lever arms |06, moving said armsl from left to right as viewed in Figure 1; this movement also moving depending arm E5 from left to right to lower the die head. The upper ends of arms |06 carry a cam follower roller |01 to engage the adjustable cam face |00 carried by the arm E0.

It will be noted that the cam |04 has an arcuate periphery of sufficient extent to permit continued rotation of the cam shaft in a counterclockwise direction after the head is lowered, and thus the head will be maintained lowered for a considerable portion of the rotation of the cam shaft; this formation of the cam causing the latter to maintain the head lowered during the succeeding operations which are eifected by other cams upon the cam shaft until the direction of rotation of the cam shaft is reversed by clutch mechanism.

The lowering of the head tensions a spring |09 which is secured at its upper end to an arm ||0, rigid with rock shaft l2, and at its lower end anchored to a cross rod carried by the machine frame. When the direction of the cam shaft is reversed to release the pressure of cam |04 upon lever arms |06, the spring |09 automatically raises the die head.

The construction and operation of the infolding means is described in my prior Patent No. 1,698,469, and the construction and operation 0f said means in Figure 1 is the same as in said prior patent, with the exception that I nowvprovide two infolding dies with suiicient additional mechanism to operate the same.

Therinfolding means are shown in Figure 1 as comprising infolding dies 3, 3 carried by infolding die carriers said carriers being connected with slide blocks ||2 by means of a pluralityof at links ||3. Said flat links are so disposed as to not interfere with the ngers 2l when the latter are retracted when the forming die is 10W- ered onto the bed plate. The slide blocks are formed to receive the eccentric ends of short vertical shafts ||4 and H5, extending through bearings in the top of the table I2, and carrying at their respective lower ends bevel pinions ||6 and IIT, adapted to mesh respectively with bevel segmental gears H8 and H9. Segmental gears ||8 and 9 face toward opposite ends of the machine, for a reason which will presently be apparent. The segmental gears 8 and |9 are rigidly carried by rock shafts |20 and |2|, which shafts are supported by suitable brackets attached to the machine frame.

Rock shaft |20 is provided with a depending segmental gear |22 xed thereto, and meshing with a complemental gear |23 of segmental form having secured to one side thereof a cam follower roller |24 which is engaged by a cam |25 on shaft |03 and adapted to be moved in a counter-clockwise direction upon rotation of the cam shaft in order to force gears |22, |23, from left to right, as viewed in Figure l; this movement rocking shaft |20. Rock shaft |2| will be rocked simultaneously with shaft |20 by reason of a link |26, pivoted at |27 yto one side of segment 23, and

linked at |28 to a crank |29 rigid with shaft 2| The cam is of sufficient extent so that it does not completely pass the roller |24, while moving in a counter-clockwise directiomand at the termination of the rotation of the cam shaft in a counterclockwise direction, the cam is still in engagement with the roller |24 and maintains the infolding dies in advanced position over the material. Upon the reversal of the direction of the cam after completion of the various operations, its engaging surface will pass roller |24, whereupon the spring |30, secured at one end to gear |23, and at its other end anchored by eye |3| to the front of the machine frame, will retract the infolding dies by moving the gears |22, |23 from right to left, as viewed in Figure 1.

Obviously, the details of the preferred embodiment described may be modified materially without departing from the invention.
