- )The steam chamber 14 is provided at-its top with :a' large annular flange 31, integral with it, and resting upon this; flangeis a :95 gasket 32 of annular form.. t

' Engaging this gasket is a large annular flange 33., carried by a lfing E i. This ring is integral with theflangei83 and extends upwardly from the tap of the Steam jcham- 9 j a handle 37 whereby it may be turned back and forth, as hereinafter more completely described.

A hat forming ring-380i large-size is located above the cam ring 35. A spider 39 is'detachably mounted upon the hat forming ring 38.

' The spider 39 carries adotvel pin'4O extending upwardly upon it, and is provided with a nipple 40a. The purpose of the nipple is toallow thepassa'ge of steam upwardlyfrom the steamchainberl4l Reamupon 'th spider 39; are spacing "disks 42. 43,-a1'id resting'upon these spacing disksis'the hat bloclt} shown a't' 44.

'lt'is hollowxand is provided with a bottom 'wall of annular form, servingas a base: and with openings 4 6"and47,and withperforations'flsf The opening 46 is for fittin'gjover the nipple 40a, and the opening 47 is to fit over the dowel pin 40." Thu s the jspacing'blocks 42, 43 and thehat block 44 are held together in group formation by means ofthe nipple 40a and dowel pin 401 p f 1 Each spacing block 42, '43,, has the form shownin Figures and {is-provided with a dowel hole '48 afor registering with the dowel hole 47' of thefhat bloclnfll" 1 *A hat crown 49 anda hat brim'50 together constitute 'a'hat'body;

. -A- forming ring, for the purpose of shaping-the hat body, and" particularly forldemarking the brim from the crown, is shown at 51.

The-forming ring 51is detaehably mounted'upon and carried by'aring carrier 52, of the form shown more particularly in Figures 6 and 7-. This ring carrier is hollow, but being made of metal-and of rather massive" constr'uctionit isquiteheavy. -gThe-fo'r-ming 51 is provided with a pair of bolts 52a, by'aid'whereof it is detach ably connected with the ring carrier 52, as may be understood from Figures 6 and 7 The ring carrier 52 is provided with a pair radially inward. v v

For the purpose of raising andlowering ofears 53, 53, integral with itand extending the-ring carrier 52 I provide apair of guide rods 55,55, extending vertically and provid+ ed with threaded portions 54,54.

Engaging these threaded portions and exprovided with threaded necks 59, 59. These are-simply threaded portions of reduced diameter as compared with the threaded portions 54,54, and are integral therewith.

Fitted upon the threaded necks 59, 59 are nuts 60, 60-, whichextend through holes 61, 61 in the ears 53, 53, as may be understood from Figure 2. Byfthisarrangement, the ring carrier 52 is mounted firmly upon the lower ends of'the guide bars 55. i The guide'bars 55, 55 extend through bearings 62, 62', supported by the cross beam 8, and are free to slide vertically in relation to these bearings.-

F or the] purpose of raisingand lowering the ringcarrier 52 by means of the guide rods 55, '55, I provide-a flexible supporting member 63, such'a's a chain, this being connected with-a sector '64 asindicated more particularly-in Figures rum 2. j a

The sector. 64 ismounted firmly upon a shaft 65, and connected rigidly with the latter is a handlever' 66, whereby the sector may bero'ekedupon the axisof the shaft 65. This shaft is journal'ed upona hanger 67 and carries a counterweight 68,- for balancing the hand lever 66. 1 ' f The'guide rods 55,55 carry stop collars 62a, 62a. These stoi collars areadju'stable relatively to the guide'rocls, and ar'e'ada'pted to rest upon the bearings 62, 62, so as to support' the weight" of the ring carrie1'l52 and parts carried thereby. v Y 1 Whenever the guide rods 55, 55 are moved downwardly to their limit of travel,- the stop collars 62a, 62a, carried by the-guiderods, lodge'uponjthe bearings 62 '62, so thatthe weight of the ring carrier '52 and forming ring 5liis now supported by the stop collars. 5 Thus'when the ring carrier 52 and forming ring 51 occupy their lowermost positions, they-aresimply suspended from the stop collars, at a. predetermined exact distance above tl'ie' spider 39, thisflistancebeing determined by the adju'stment of thestop collars 62a relatively' t'o the guiderods'55, 55. 'Th'e operator, by graspingth'e hand lever 66 and operating it, canraise or lower-the ring carrier. 52, withth'e'forming ring 51, so as to bring the forming ring down upon a hat brim, at a predeterminedlevel above the spi der 39, and thus at-a definite distance below the topfof'the hat crown, as shown in Figure 2.. Thus the forming ring demarksthe hat crown from the. brim, :and assists in forming thehatv A cam. ring 35 is associated with a number ing-the handle 37 and turning the cam ring in a clockwise direction according to Figure 3, causes the several rollers 71 to be forced radially outward.

'The hat forming ring 38 is provided with a number of slideways 69, extending radially outward, as may be understood from Figure 3.

There are eight of these slideways, ar-

ranged in the proximate form of a circle; only three of them, however, being shown in Figure 1. I

Mounted within the respective slideways 69 are slides 70, adapted to be moved radially inward and outward relatively to a common center.

Each slide 70 carries a cam roller 71. The cam rollers 71 extend downwardly, into engagement with the faces 36 of the cam ring The operator, by grasping the handle 37 and rocking the cam ring back and forth, causes the slides 70 to move radially inward and outward. That is, the slides move outward as the cam rollers 71 are forced outwardly by the cam faces 36, and move inwardly by the tension of the springs 75.

Each slide 70 carries a gripping lever 7 2, mounted thereon by means of a bearing 73.

Each gripping lever 72 carries a jaw 74, facing downwardly as indicated in Figure 2.

Each slide carries a pair of tensile springs 75, and these springs are connected with the bearings 73, so that the tensile springs tend to move the slides radially inward.

Each slide 70 is provided with a jaw 76, facing upwardly and mating one of the jaws 74.

For the purpose of actuating the gripping levers 7 2 I connect these levers with pull rods 77. The pull rods extend downwardly, and at their lower ends are connected with a spider 78, the latter being connected with a treadle 79, as shown more particularly in Figure 1. The treadle is journaled upon a cross rod 81.

Another cross rod 82 serves as a limiting, stop for preventing excessive upward travel of the treadle.

The spring serves to retract the treadle 79, and by so doing to move the pull rods 77 upwardly, thereby causing the gripping le vers 7 2 to rock, so that each jaw 7 4 is moved downwardly toward some one of the jaws 7 6.

The operator, by releasing the treadle 79 with his foot, so thatthe jaws 7 4 move downwardly toward their mating jaws 76, thus causes the jaws 74 and 76 to grip the adjacent edge of the hat brim 50, if such hat brim is in the position indicated for it in Figure 2.

If, next, the operator grasps the-handle 37 and rocks the cam ring 35 so as to force the cam rollers 71 radially outward, the brim 50 of the hat body is stretched. V

I will now describe the several successive steps which take place during thetreat ment of a hat body. I v

. Assuming the machine to be in the condition indicated in Figures 1 and 2, the oper ator first raises the hand lever 66 to the upper limit-of i tstravel so that the ring carrier 52 and the forming ring 51 are-lifted clear of the hat block 44 and out of the way.

At practically the same instant, the operator. depresses the treadle 79 and thereby rocks the gripping levers '72, so that the jaws 74 are raised, and the-hat brim is released. The operator now removes the hatbody, and this leaves the machine clear.

The operator still keeping the treadle down, next fits a new hat body in position, so that the crown covers the hat block and the brim; extends loosely between the gripping jaws 7 1 and 76.

Next the operator lowers'the hand lever 66 andbrings the ring carrier 52 and forming ring 51 down, so that their weight is now supported mainly by the stop collars 62a, 62a, the forming ringthus fitting rather snugly around'thel'bas'e of the crown, and serving to demark definitely the crown and brim. Next the operator allows the treadle 79 to rise, which it readily does under tension of the spring 80, 'and'this" causes'the gripping jaws 74 and 76*tjo gripthe edge of thebrim.

Then the operator grasps theha-ndle' 37 and rocks the cam ring 35, causingthe cam rollers 71 to carrytheslides radially outward stretching the hat brim tightly. "I

' Next the operator admits steam'fro'm the steam pipe '16 and nozzle 15 into the, steam chamberli. 'Steam 'from the "steamcha' mber passes upwardly through the nipple40a into the hollow hat bloeli 44:, and 'thence through the perforations 48 and through the substance of the hat crown.

The action'of the steam'upon the hat crown is to soften the material. and render it somewhat plastic. so that under the stretching action to which it is being subjected it is made to fit neatly upon the hat block. its form for this purpose being rendered both definite and accurate.

The hat bodv being thus properly steamed v and formed. the operator cuts off the supply of steam, and subjects the steam chamber 14 to the action of the suction blower, not shown,

to which the pipe 29 leads.

This is conveniently done by simply opening the gate 30. This removes the steam from the steam chamber, and dries the hat body.

The operation is then repeated, as often as there are hat bodies to be treated.

The hat forming rings 51, being interchangeable, are of different sizes, for the purpose of accommodating the machine to bat bodies having hat crowns of different sizes.

In order to change the depth of the hat interchanged asoccasion may require, and as above described. v

' I do not limit myself to the precise mecha nism shown, asvarlations'may be made thereimwithout departing from my invention, the scope of which is commensurate with my claim. Y v 1 i Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows f V In a machine for treating hat bodies, the combination including means forming a steam chamber having a top wall with an bodyextendlng radially across the top wall of'thesteam chest awayvfrom said hat block, v a rpluralit-y. ofxgripping members slidably mounted upon said top'wall to slide radially thereof toward and away from the hat block adapted for gripping the-brim portion of the hat body and stretching the same radially across the top wall of the steam chest away ,fromthehat block, and operating means for .1 r a said forming ring and said gripping members.- .e
