HAT-ERIM MOLD..

l SPECIFICATION forrningpart of Letters Patent No. 302,118, dated July 15, 1884.

` Application filed November 14, 1883. (No model.)

To @ZZ whom t may cancer-it:l

Be it known that I, RUDOLF EIOKEMEYER, of Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Hat-Brim Molds; and -I do hereby declare that the `following specification, taken in connection with the drawings furnished, and forming a part of the saine, is a clear, true, and complete description of my invention. y It is well known that-after hats having sti or half-stiff curled brims are otherwise finished it isi always requisite that said brims receive more or less attention and labor for develop# I5 ing their proper curves and outlines, and that sometimesthe edges ofthe brims'are squarely' turned inward, sometimes rounded, and sometimes folded iiatly inward and upon the upper surface of the brim. This molding operation is performed while the hat or brim is well heated and softened, so that when cooled the form of brim attained in each case willbe well set or fixed. Y

Heretofore, as a rule, brim-molds havebeen employed having a surface contour and dimension properly suited for the largest size contained in each assorted dozen of hats, and the several smaller sizes in each dozen, varying one-eighth of an inch in diameter from size 'to size, are operated upon in the same mold, which necessarily involves much labor? and a high degree of skill in molding the `brims of all such hats which are smaller than those to which the mold is exactly adapted, and with such prior molds but few workmen are sufficiently skilled to turn out a dozen hats of assorted sizes having brims which are approximatelyuniform in form or contour.

.The objects of my invention are to enable the brim-molding operation to be more rapidly performed lby comparatively-unskilled workmen and with less IabOIKthan heretofore required, and also to enable the wo-rk to be performed in a better manner, and so that brims of all widths and upon hats of all sizes may be properly molded with absolute uniformity and with equal symmetry Of contour. These results are due mainly to the fact that I employ a novel brimfmold devised by me, 5o which broadly differs from all others of which I have knowledge, in that it has a practically continuous Outline and molding-surface, although itis sectional in construction 5 and,also, inthat it is capable of Aexpansion from one size to another without breaking the conti- 'nuity of its outline or its' molding-surface; and, still further, in that its molding-surface is One towhich the underside of a hat-brim is made to conform, as distinguished from certain prior brim-molds constructed in two sep- 6o arable parts, and having a moldingsurface to which the upper side of a brim is made to conform. In its best form my mold is capable of expansion from the smallest dimensions required to the greatest; and I have provided means whereby necessary variations in its adj ustment may be promptly and, accurately made, so that said. moldmay be` readily set for properly molding the brim of any hatv and as readily changed for a hat of the next larger .7o or next smaller or any -other size, thus enabling a workman of ordinary skill to operate in brim-molding with equal facility upon hats of all sizes, with the expenditure of but little more time than is requisite for the cooling of the brims to such a degree as will warrant their removal from the mold. My brimmolds are variably so constructed as to properly engage with the edges of brims which have been turned squarely inwardy or curled,l and thereby to cause the brims to readily conform to the contour of the mold with but little manipulation or hand-pressure. A I have illustrated in my drawings,andhere inafter particularly describe, the construction of an expansible brim-mold, fromwhich it will be readilysu'ggested to skilled persons in the art that many variations in construction may loe madefor producing a brim-mold capable oi use with novel results approximatingmore or-less closely to thoseobtained by me with the one described, and it isto'be understood that I do not preclude myself from employing other substantially similar constructions. In` developing the said expansible brim-mold into its best form, I have `embodied therein some of the principles which are involved in the ex pansible hat-blockshown and' described in my Letters Patent No. 141,338, dated July 20,

1873. It should be understood, however, that roo all expansible hat-blocks actively operate within a hat for forcing the crown into a certain form, an d the expanding devices employed therewith are the means by which the requisite forcing-power is transmitted to the block; but, on the contrary, my novel expansible brim-mold serves merely as a variable matrix or mold for presenting suitable surfaces, against which the brims are pressed for securing their desired form or contour, and the expanding and contracting devices used with said brim-mold in no manner operate upon the hat, but only enable the size of the brim-mold to be readily varied.

To more particularly describe my invention,

I will refer to the accompanying two sheets of drawings, in which- Y Figure l, Sheetll, illustrates one of my brimmolds in central vertical section as :mounted for use. Figs. 2 and 3 are respectively vertical central sectional views of a portion of a brim-mold table and the means whereby the size adjustment of the brim-mold may be readily and accurately effected. Figs. 4 and 5 are vertical sectional views of the brim-mold detached, each being on a line at right angles to the other, and showing a hat in central section thereon crosswise and also lengthwise. Fig. 6 is a sectional view of one side of abrimmold as constructed for operating on a hat with a rounded edge brim. Fig. 7 is a top view of the brim-mold. Fig. Sis a top view of certain radially-slotted plates which are embodied in the brimmold.

As shown in Fig. l, I provide a suitable table, A, having a foot -plate and a suitable standard or standards. The expansible brimmold B is mounted upon said table, the top of which is usually oval'in outline, and has a smooth-planed surface. Said mold, as here shown, is composed-of thirty sections, a.; but the number thereof may be obviously varied without materially affecting the results desired. Each section is widest at its outer end, and has atop or bearing surface,which in forni or surface contour corresponds with the desired shape of a hat-brim at the corresponding portion thereof-as, for instance, the sections at the side of the mold have bearingsurfaces which curve upwardly, and those at the ends ofthe mold curve downwardly, as clearly indicated in Figs. et and 5. Each mold-section a has aiiat angular shank, a', and said Shanks are of the same length, and so finished at their lower ends that each rests squarely upon the smooth iiat surface of the table A. Each section-shank a oceupiescoincident radial slots a? in the two upper and lower cone-plates, Z) and Il, said slots having inclined ends, which conforln to the inclination of the edges of said shanks, so that when said cone plates are raised or lowered the several sections are simultaneously moved outwardly or inwardly; and to secure a proper radial movement of the sections I employ between the cone-plates a guide-plate, c, which has long radial slots occupied by the section-Shanks, and it is rigidly confined in place by standard-bolts c', which project upward from the table A, as clearly indicated. As a rule, the weight oi' each section is sufficient to cause it to always remain in supporting contact with the top of the table; but to prevent its vertical movement, if desired, each shank a may be provided with a lateral pin j ust below the guide-plate c, as is indicated at c in Figs. l, 4, and 5.

As seen in Fig. 4, the brim-mold is shown in solid lines, as when adjusted for a largesized hat, and in dotted lines as when adjusted for a smaller size. Vhen adjusted for the smallest-sized hat, the edges of the several sections are nearly in contact with the edges of the next adjacent sections; but when the mold is expanded intervening spaces occur between said sections; but Ifind that said spaces when widest do not result in causing-a hat-brim to have a marked or uneven surface when ordinary eare is exercised in moldiiw but in order to obviate all possibility ofso marking or ridging the brims, especially on fine halfstift' hats, I sometimes provide for an absolutely smooth and unbroken surface of TOO mold. If a rounded-edge brim is to be molded,

the sections at their outer ends are so curved as to afford the desired contour, as illustrated in Fig. G. It is to be understood thatthis feature of providing a brim-mold with an inwardly-turned surface at its edge is, broadly, new, regardless of the construction of the mold in other respects; and while said edgeconfining surface would have less value in a solid mold than in my sectional mold it can be therewith profitably employed, especially if said inwardly-turned surface be afforded by plates which are movable, so that a hat, when its brim has been molded and cooled, can be readily withdrawn from the mold; and I am well aware that if the molds with said inwardly turned surfaces be arranged for working upon hats of one size only, or upon not more than two or three sizes, they can be profitably employed when considered with reference to the solid molds heretofore used; and so, also, am I aware that the novel seetional brim-mold, however it may be enlarged or contracted, has practical value even when not provided with said edge-confilling` surfaces. In this connection I will again refer to the prior two-part brim-mold, having a moldingsurface to which the upper side of a brim is made to conform, and further explain that such molds, when expanded, afford only a in olding-surface for the front and rear portions ITO therein, but the mold when next expanded is retired wholly from the periphery of the brim and enables the hat to be removed ,from thev mold without in any manner deranging the form imparted to its brim.

On referring to Figs'. 7 and 8 it will be obvious that thesections move in lines radiating from several cent-ral points, and that therefore every portion of the molding surface always maintains its proper relations with those on either side; and hence the mold can be uniformly expanded and contracted, where-.

as in a two-part mold as heretofore constructed there is4 and can be no uniform expansion of the molding-surface,but only a longitudinal enlargement thereof on a central line, and-such molds are concave on said line, while mine are and must `be arched or convex on that line,

as clearly indicated in Figs. l and 5; but crosswise of the mold it is more or less concave, according to the character of theupward curl to. be molded at the sides of the brim, as clearly indicated in Fig. 6; and if brims shouldbe desired having little or no arch from front to rear, vbut having an upwardly-turned edge, it will -obviously involve only a corresponding change in the surface contourof the sections.

It will be seen, regardless of the particular construction of the sections and the manner in which they :are expanded andthe means employed for expanding them, that said sec- .tions as a whole serve as avariable matrix or mold within which hat-brims of all the usual widths maybe molded, and therefore I broadly claim as the main feature of my invention a sectional mold, substantially as described, regardless of the particular construction thereof, provided it be capable of receiving a hat in au upright position and of molding its brim by the contact of its under side with the molding-surface of the mold.4 Itis, however, iniportant for obtaining the best results in the matter of economic operation to provide for` readily changing theadjustment of the brim- '1nold, and also for some convenient means by which changes from any one .adjustment to another can be promptly and accurately made.

The lifting and lowering of the cone-plates can be accomplished, or` equivalent devices may be moved to and fro for expanding and contracting the brim-mold, by means of. levers of various `kinds or by cams, without depart-- nre from certain portions of my invention; but in order that the workman may have his hands free for handling hats I have provided a treadle by means of which the brim-mold is expanded and contracted, and I have also provided graduating devices by which the size of the brim-mold may be accurately varied. It willbe seen that the two cone-plates b and b are coupled together by means of a sleeve, d, and that a treadle, e, is connected tothe lower plate, b, by a pair of rods, e. The treadle c has for its fulcrum a rock-shaft, e2, to which a weighted arm, ci, is connected,so `that the treadle is normally elevated, thus normally maintaining the cone-plates b and b in an elevated position and the brim-mold in an ex- .SOP

panded condition, ready to receive a hat-brim,

vwhereuponthe treadle, on being depressed,

contracts the mold to the proper size for molding said brim,'and it is so held while the brim is properly pressed orV worked, and thereby madero fully conform to the .surface of the mold. If it be desired to leave the foot of the worl'man'free while molding .a brim, a catch may be employed .for holding the treadle down until the hat is ready for removal, which of course must be preceded `by a release of the treadle and anexpansion of the mold for releasing the brim; or the treadle and weight 'may obviously be so mounted as to normallymaintain the brim-mold in a contracted 'condition, sothat on depressing the treadle the mold will `be'expanded to receive a hat-brim,

v,and by then permitting the treadle to rise to the required point the proper size of the mold can be obtained, in which case an adjustabletreadlestop can be employed 'for holding it in position while the hat-brim is molded. It will IOO be seen that it is the inwardly-turned surface v on eac-h mold-section which prevents a hat from being removed from the mold, except Vafter expansion; but said edge-confining snrfaces may obviously be afforded by means of plates movable independe'ntlyof the sections, so that a hat could 7then be released, if desi red, without theHexpansi-on of the mold itself.

For obtaining ready and accurate adjustment of thebrim-niold, it is necessary to provide a' readily-varied, stop, which shall limit the downward movement of the treadle, and

thereby limit the inward movement of the expansible brim-mold. i In Figs. 2 and 3 Ishow a revolving vertical graduating-screw, j', hav- `ing bearings at top and bottom within the standard of the table, and to said shaft a bevelpinion, f/, is keyed, which meshes with a similar pinion on the hand-crank shaft g. Tapped upon the graduating-screw is a cross-head, 71

having at its ends holes` for loosely receiving the treadle-rods c', Aeach .of `which is provided with a collar, h', having a set-screw. It will be readily obvious that if the cross-head, serving with the collars hl 'as a variable stop, be raised or lowered that the treadle will be correspondingly limited in lits downward move?. ment, and the brim-incid will consequently be limited to a certain degree of contraction; or, in other words, the mold will be exactly adjusted for molding ahat-brimof a certain size, atthe same time permitting `the mold toA expand for releasing the hat as soon as the treadle is allowed to rise.

lt will be obvious that ifa treadle should be employed which would on rising contract the brim-mold the collar-sh would belocated below the cross-head instead of above it.

As each size of hat varies-from those next larger and next slnaller just one-eighth of an inch in diameter, I use a graduatilig-screw of such a pitch that with one turn of the crank it will so move the stop as to vary the eontraction of the mold one-eighth of an inch, so that the workman, knowing of the last adliustment employed, can readily change to a larger or smaller mold with absolute accuracy by giving the proper number of turns to the hand-crank, and a consequent proportioned rotation of the graduati11g-screw,which might obviously be provided with a handwheel in lieu of the crank.

I have thus far described the brim-mold without any means for enabling the brim of a hat to be promptly and accurately adjusted coneentrically within the mold, it being obviously practicable to obtain desirable results without such means, although they contribute greatly to economy in mattei' of time in the molding of brims. I have therefore provided a hat-block plate, i, on top of a spindle, i', which has its step within the standard of the frame, and said spindle serves also a good purpose as a guide-bearing for the cone-plate sleeve d, before described, although if the treadle rods c be properly supplied with guide-bearings, no other would be absolutely needed. The hat-block plate has on its upper surface a central pin, (the top of spindle l1",) and also two additional pins, il, with which corresponding holes in a hat-block, 7.', register, as indicated in Fig. 5, so that a hat on .such a block placed within the mold will be always readily and accurately centered.

In lieu of the ordinary hat-block, itis obvious that I can employ an expansible hat-block without departing` from the main features of my invention.

Having thus described my invention,l'V claim as new and desire to .secure by Letters Patentl.
