HAT-FORMING DIE Applicationiled May 22, 1926. Serial No. 111,017.

This inventionl relates to hat making or forming dies and more particularly to a novel and improved method of shaping the material to produce what may be termed a` full 5 crown or flat crown turban hat.

The primary object ot the invention rer-- sides in the construction of a hat shaping and forming die designed to steam theamaterial during the Vforming or shaping p-roc` 10 ess, @including provision or'making various sized and shaped hats with rapidity and skill and with a minimum amount of hand labor.

One of the objectsof myzinve'ntion is to provide ia steam? chamber or formingdie 15 into which the Vmaterial to .be pressed Vor shaped nmaybe held, the same being soA arranged that the material to be pressed or shaped will be held therein in proper position andthe die will be so formed that it is 29 readily adapted to receive the shaping member. .f

Trouble has been experienced inl applying to the interior of the die-a. `forming member' between the walls of the die'and itself, theV material Ito be shaped,l which, at the same time `may be steamed-dueto the construction V of the die. n

A further Particular object of the inventionl is to construct the die and itsparts so that-either a full crownturban may be formed or a flat-crownturban, the arrangement ot the dies'being provided so that the goods may be interiorly` worked or eXteriorly worked dependingupon' the shape of ,the hat desired.

VMy improved construction is especially adapted for :tormingvoutot1 the stock mate- V rial, yelour, eltVbeaver or buckram or the like,` a hat,-the` forming `member and dies being so arranged that they vcan be readily disassemble'dtor..cleaning and will have few numberofvparts.whereby they can be quickly assembledor replaced `to provide various forms of dies, depending upon the shape of hat, the construction of which is contem-` plated. Y

To enable others skilled in the art to fully comprehend the underlying features of my invention that theymay embody the same in the 'various modifications rin structure `con- "Y templated, drawings depicting a preferred form'havebeen annexed as a part ot' this' disclosure and in such drawings, similar'reterence characters denote corresponding parte throughoutV all the views, of which, j

Figure l is a view of the upper or working portion of a die machine in which is formed or blocked the material making up hats and showing the hat material in place within the die readyto be formed by a sack forming member which I employ.

Y Iigure 2 is an enlarged Y cross section through thedie and the sack holding membernand illustrating the construction of both.

Y`Iifgure` 3 is ai crosssection taken through a hat constructed in the die shown in Figure 2, and providing the full crown eiect as desired.l Y l Figure 4 is a modified form ot sack or pouch such as shown in Figure l but having formed therein an enlarged body portion. y

Referring to the drawings in detail, 5 indica-tes the die holding trame of an operating machine, such for instance, as thef ma` chine shown in my Patent Number 1,530,001 granted March 17, 1925. The cross head 6 thereof is a'djustably carried by the screw members 7 which are operated in any suitablemanner to raise and lower the die carrying ltrame 8 which consists of a plurality ofpost members, holding at their lower ends, the sack carrying plate 9. This plate is provided with a boss l0 in which is threaded an air hose connection ll through the medium of which air may be supplied to the interior of a rubber or other yieidable sack 12, where by the same when placed within a hat forming guide, may be inl'lated and depending upon the air'pressure Supplied through the connection ll will press the hat material between the sack and the inner walls ot the die.

In the invention shown vin Figures l, 2 and 3 and l, I have illustrated one method of IUD working a hat, the hat being of the turban type and being interiorly worked to provide therein the shape desired. ln order to hold the sack 12 in position on the carrying plate 9, 1 provide a clamping ring 13 which is secured to the plate 9 through the medium of the screws 19C, shown in Figure 2. The sack is susnended from the plate 9 and is in position directly over the die and being carried upon vthe threaded members 7, can be lowered into the die at will to be subsequently inated to shape the hat material. In Figure 1, l have shown in position in the die member, cone-shaped material made of velour, felt, beaver, buckram or the like material suitable for the manufacture of hats as .supplied or ready cut in the trade.

It will be noted that this cone-shaped piece of material 15 is disposed within a hollow die which is in the nature of a pot, the lower portion of which is bowled, it being of course understood that any shape et die member may be used, depending upon the shape to be given the hat which is to be blocked. rlhis dic member is suitably secured' to the top plate 1G of a steam chamber 17 'through the medium of the screws 18, the upper wall of the die being thickened as at 19 and having its inner circumference shaped as at 20 to accommodate a holding or wedging ring 21. The die 19 is provided, as is the plate 16, with perforations or openings 22 through which the steam may pass to affect the material to be blocked in the usual manner. The steam pot 17 is smaller` at its base than in its upper portion and through the medium of the lugs 23 and thumb screws 24, the same is suitably secured to the bed 25 of the machine hereinbefore referred to. The steam pot has the usual steam inlet 26 and outlet l27 through which the same upon manipulation of the valve 28 can be supplied with steam to affect the material to be blocked.

Referring to Figure 2 particularly, it will be noted that when the material 15, which, as before mentioned is sold in the trade in substantially conical shapes, has been placed,

as shown in TFigure 1 into the die 19, the holding or clamping ring 21 is placed inside the hat material 15 and fastens the same to the upper edge of the die, the holding rings securing the same in position in the die through the meeium of its frictional contact with the curved wall 2O of the upper, inner periphery of the die as hereinbefore eirplained. lWhen this ring 21 has been positioned, the upper edge or protruding portion of the hat material is turned in over the ring at 29 and the upper frame or head 6 of the machine is lowered until the sack 12, as shown in outline in Figure 2 is resting in position upon the material in the bottom of the die. lt will be readily seen from Figure 2 that when the-sack is inflated under pressure, the same will take substantially the contour of the die or the material as turned in and will effectively block the same to the shape of the die, it being of course under'- stood that various shapes of hats may be provided by changing the inner contour of the die. i

When the hat has been blocked to the shape desired, the inner fold 29 is drawn out and the ring 21 removed, after which the extended portion 29 of the material is cut oli' or the inturned portion of the material is trin'nned as desired and as shown in Figure 3, a hat of the full turban design is produced.

lt is to be understood that any shape of sack may be used or that the sack may be made of any suitable materialv such, for instance, as rubber, rubberized cloth or any air-proof or steam-proof material, also, any of the parts of the device, such for instance, as the blocking core orshaping ring may be made of metal or rubber as desired and that anyshape of die may be used, depending upon the style of hat desired.

It is evident, therefore, that l have provided an etlicient means for interiorly and exteriorly blocking or Working hats. In this particular instance, I may designate the hat as of the turban style but it is to be distinctly understood that a hat of any style can be formed through the use of my blocking element.

The process of blocking the hat, as shown in Figure 1, would comprise the placing of the material into the die and then placing the ring into said material so that the same was wedged in position in the die. `The material is then folded in and the sack lowered thereinto so that it will shape the crown and produce the proper head size. After the blocking' has been completed, the material is removed, allowing the holding ring 21 to fall into the pot or die after which the material is trimmed as desired.

It will be seen therefore, that I have provided an improved method of shaping and blocking a hat which could be varied to suit the shape desired and also wherein modiications as to size and form may be readily accomplished.

'lNhile I have illustrated and described my invention with some degree of particularity, realizethat in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts with out departing from the spirit of the invention or the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is A hat shaping device comprising a steam pot, a closure forv the top of the pot, a perforated die suspended from said closure, and

having an outwardly ared upper edge and adapted to receive the material to be shaped, a wedging ring tapered in cross-section insertible into the upper flared edge of the die Jfor holding the material in place against said flared edge and over which `the excess material can be turned into the die, said ring vmaintaining its position within the die by frictional Contact of one of its tapered sides with the flared upper edge of the die, a sack carry ing'plate having a pressure inlet, an inflatable sack carried by the plate, means for moving the plate to position the sack exteriorly or interiorly of the die, a clamping ring for retaining the sack in position on the plate and said Clamping ring being arranged t0 engage the wedgin g ring whereby the hat Inaterial will be held securely in position during a shaping operation.

In testimony whereof I affix my signature.
