.- To all whom it may. concern: V

Be it known that I, JAMES LAKE, Jr., a citizen of the United States, and a residentof the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, have invented anew and 1m proved Hat-Machine Press, of which the following is a full, clear, and exact description. 7

Among the principal objects which the presentlnvention has 111 character. mentioned from opening accidentally; to provlde manually-controlled means for opening and ClOSlIlg-SitlCl press rapidly;-

chine; to provide means for adjusting the working positions of various portions of the press; and to simplify the construction and to strengthen the same.

. As seen in the drawings, the hereindisclosed press has a stationary press-head cylinderlo. The cylinder lfz is permanently. attached by brackets 16 to-fa stationary cross head 17. The cylinder 15 of thepresent disclosure is int'eriorly equipped in sulos tan;

' tially" the same manner and ,with similar elements as thoseshown in" a patent granted, to meunder date ofJuly 18, 1916, and umbered'1,19l,709, to whichapatent crossref+ erenceis here made. fllVherea's, however, thepress-head cylinder in the former patentis reciprocated together withthe cross head which it is supported, 'inthe present ma- 7o chine both the cylinderl'5 and the cross'head 1 7 are stationary. I lhecross head 17 is supportedjhy framinglegs 18,1 the feet '19- whereof form the supportinglfoundation for the machine. Theleg's 18 at the lower endsYjS which prevents the said] legs v eral extremities-of the heating table 23, and

the reinforcing finst2 lthereo-f. The table 23 v v has a centrally disposed,{cylindrical chamher for holding a crown shape above a tip petj member, movably 'mounted therein and iSj adapted for'supporting a removable brini' die 25, the, contour whereof c0rres1'5onds -to" the shape to be imparted to the brim of the p'res'sureis 'applied by a flexible hat when face forming theinterio-r ofthecylinder15,"9o l as more fully set forth in-thejpatent' abovef referred to. r r 1 The weight; of the ,table 23 and parts attached thereto ispa'rtially counterbalanced. by'the block 26. I he block 226 is operatively connected with the runner'blocks 22 ."byca- 1 bles 27, which are rove'd'over; pulleyseg-- ments 28 and 29', and are connected to the v blocks 22 bypivot heads 30' andrpins 81.

The opposite ends of'fthecables 27 are at 10o tachedto the eyelets 32in'eye-bars 33.; The eye-bars 33 are'provi ded as guides for supg 1,429,0ee

plemental weight 34, which may be added to the block 26 to augment the effective weight thereof.

The table 23 and parts supported thereby are elevated and lepressed by a mechanism manually controlled through a lev r bar 35, the hand grip 86 whereof is grasped by the attendant of the machine when desired, to move the lever from the position saown in Figure 3 to that disclosed in Figure 2, the result of which is to move the table 23 into closed relation with the cylinder 15.

I The mechanism for elev ting the table 23 above referred to, con ts primarily of toggle frames the links 3'? whereof are imauy connected by pins 39. The pins 39 also serve to connect the strap links 10 with the links 37 and 38. The strap links 46 are connected by pivot pins n, with roclnng arms 4:2 which are mounted on the square shaft The square shaft 4-3 is pivotally mounted in hearings in brackets 44 eiztended from the bolting plates 45. The brackets i l are. integral with the plates 45. and have feet a6 'which rest against the web of one of the l-beams framing the adjustable cross, head 917 On the lateral extremities of the cross-head 4'? is integrally formed a runner block ii-7 slidably confined in each guideway to hold the crosshead in vertical alignment with the machine. The cross head l? is complementary to the cross head 17, and is structurally connected with and suspended from said cross head 17 by the four suspension rods 4 8. The rods 4-8 are held 1n parallel ahnement by the bolting plates l-5 and 49, and extend through recesses in the exposed flanges of the I-beams forming the cross head. The extremities of the rods 48' are'threaded and provided with nuts 50. The nu ts are adjusted to extend or contract the distance between the cross heads 17 and 47. This distance, it will be understood, corresponds with the height of the die 25 and the consequent working level of the table 23 in relation to the cylinder 15.

As seen best in Figure 6 of the drawings the link 3'? has a rearwardly-extended toe 51, a rearwardly-extended heel 52 being formed on the edge of the links 38. The abutting surfaces of the toe and heel mentioned are dressed or machined to rest firm- 1y upon each other when the toggle frames formed by the lin Is 37 and 38 are in locked position or in the position where the planes of the two frames are angularly disposedi the connecting pivots thereof having passed the alane coincident with the hinoge nivots' thereof. In this position, the toes 5] and heels prevent the frames from further forward movement when pressure is applied "to the table while the angular disposition of the two frames prevents a rear ward movement of the joint of the said frames. It is obvious that the predominance in length of the lever 35 over the arms 42, facilities the forceful closure of the toggle frames whereby any miscalculation in the adjustment of the cross-heads l7 and 47 may be accommodated without requiring readjustment thereof.

It will be understood that the table 23 and the die 25 carried thereby are lifted by the toggle frames and seated against the flexible inner wall of the cylinder 15 forcefully.

In the manufacture of hats for which the present machine is particularly designed the rough shapes steamed. Before elevating the table ;,3 and die :15 thereon, one of the rough shapes at each operation, is adjusted to I said die. l l hen the die is closed, the upper surface thereof presses upon and forces the brim of the hat against the inner lining of the cylinder The crown 53 with which machines of this character are usually provided is encompassed by a crown :inold 54c, section'whereof is shown in Figure 8 of the drawings, which rests on the tip plate 55. The tip plate 55 and the table 23 are steam-heated. The tip plate has a steam space 56 provided therein, which is connected by means of the pipe 5?, with a steam space 58 in the table 28. As best shown in Figure 8, the pipe 57 is telescopically mounted in a tube 59, which is connected by a short pipe nipple 66 with said steam space 58.

its shown in Figure 2 of the drawings, steam is delivered to the space 58 in the table 23 by a supply pipe 61. After circulating through the space 58, nipple 60, tube 59, pipe 57., and steam space 56, the steam passes from said steam space 56 by way of the pipe 62 and tube 63 to a waste pipe 64. A telescopic. connection is provided between the tube 63 and the pipe A supply of steam is provided for the table and the crown tip in this manner, the heat whereof is transmitted to the die 25 and mold 542. 7

As shown best in Figure 8 of the drawings, the telesco aic connection between the pipe 5'? and the tube 59, and the pipe 62 and the tube 63, is required by the nece sity for raising and lowerin the mold. 5a, to adjust the press for the manufacture of hats having crowns of various sizes and shapes. To do this, the tip 55 is raised and lowered.

Tn the present machine, to raise and lower the tip 55, screw threaded nut 65 is provided. The nut 65 thread engaged with an elevating screw 66, as shown best in igure 8 of the drawings. The upper end of the screw 66 is connected with a tubular extension 6'? of the tip 55, by means of a pin 68. The nut 65 has an annular flange 69, supported. by a cover plate 70 at the bottom of the tubular extension 71 of the table 23. The cover plate 7O is centrally provided with'a circular opening, through which a raised crown -headof the nut 65 extends. The head has permanently mounted thereon a "ratchet 72, the teeth whereof are engaged bythe tooth end of a springseated pawl 73. To seat the pawl 73, a spiral spring 7 1 is provided as shown in said Figure 8. The tooth 7 5 of the pawl 7 3 is beveled at one side to engage the teeth of the ratchet on the flat side thereof, a form of pawl-'and-ratchet well known to theart.

Provision is made by the use of the ratchet and pawl for reversing the operation of the pawl on the ratchet, which is accomplished by retracting the pawl 7 3 and rotating it onthe axis to presentthe squared face thereof in relatively opposite rotary directions of the ratchet 72. The pawl 73 is mounted in the hub of a lever 76, the hand grip 77 of which, as shown best-in Figure 3, is within easy reach of the attendant of'the machine. By operating the lever 76, the attendant can readily increase or decrease the proportionate amount of pressure of the machine on the crown without-affecting the pressure which is exerted uponthe brim of the hatbeing pressed.

1 The pressure relied upon for pressing hats is hydraulic, water under pressure being admitted to the crown bag 53, by way of the pipe 78, tube 79, pipe'80, and tube 81, which hasa-screw threaded extension 82. The tube opens within the crown bag 53 and a rigid -top plate thereof to deliver water to the said bag for pressing the crown independently of the .rlm. A screw nut having a hand wheel 83 is operated in the bowed bridge 84 to raise and lower the tube 81 and thecrown bag supported thereby. To show the pressure on the water employed 'in the hydraulic operation, a pressure gage 85 is employed. V

WVater under pressure-is supplied by the pipe 86, shown best in Figure 1 of the drawings, an extension 87v thereof entering the cylinderla within the space covered by the flexible lining of the said cylinder, which lining corresponds with the upper shape of the die 25. A valve 88 controls the flow of water through the pipe 86. I

In the operation. of the machine, the attendant having adjusted the operating position of the cross head &7 to the working position of the table 23 and partssupported thereby, places on the die 25 a rough shape and first gripping the hand rest 23, he grasps the hand grip 36 of the lever 35,

and moves the same from the position shown in Figure 3, to that shown in Figure 2, with the result that the toggle frames having the links 37 and 38 are straightened and thrown past the center of a plane coincident with the pivots of: the said frames until the toes 51 of the links ien gage and rest upon the heels 52 of the said links. In this position, the rough hat. shape is given a relatively slight preliminary pressure by the inner lining of the cylinder 15, and by the outer surface of the bag 53. In this position, the valve 89 having been turned off, the valve 88 is opened and water from the pipe 86 is permitted to flow through the pipes 78 and 87, respectively,-

to the bag 53, and the cylinder 15, imparttain pressure on the crown of the hat after the pressure is relieved from the brim thereof, the valve 91 isclosed before the valve 89is opened. When, therefore, the'v'alve 89.;is opened, it is obvious that pressure will be relieved from the cylinder 15 without relieving pressure from the bag 53.

The pressure surface of the bag 53 and of the brirndie 25 being great, the resultant strain on the machineryis correspondinglygreat. Machines of this character have been; subject to breakage for 'this reason. It is to'overcome this objection that the links 37 and '38 and the brackets 16 havebeen disposed in line and intermediate the-centerof' the machine and the rods 48 connecting the cross heads 17 and 17 By thisarrangem'ent, the lines of resistance to the strain are balanced to equalize the strain and to avoid tortional stresses on the mechanism:

It is obvious that the rapidity with "which the machine may be'operated is augmented, when by the operation ofthe single lever 35, the clamping elements of the machine'a're closed and locked in operative position. I
