v Application filed July 9,

To all whom it ma concern: i

Be it known that I, GEORGE MARGOLIN', a citizen of the :United States; residing at New York, in' the county of New'York and YState of New York, have invented icertain new and useful Improvements in Hat Stretchers, of which the following is a specificationn V This invention which relates to a device for stretching hats, either mens or womens,

. utilizes two blocks movable toward and from each other, the shape and size of the blocks being such as to adapt them to distend the crown of a hat whose size is to be increased. In such an apparatus it is my aim to incorporate certainimprovements which romote economyin construction and assem ly, facility in operation, strength and durability in service, etc. a t c.

A preferred embodiment ofthis invention is set forth in the accompanying drawing in the manner following: I

Figure 1 is aside view of the stretcher,

--partly in elevation andepartly in section,

showing the two blocks widely separated;

Fig. 2 is a horizontal section therethrough taken on line 2-2 of Fig. 1 and looking in the direction of the arrows; and I Fig. 3 is a fragmentary detail in section, taken on line 33.of Fig. 1. r

' As shown, the structure includes in its 7 assembly a board A whereon is secured as by bolts 4 a base B of any appropriate contour. Supported on the base is a fixed block 1C which, in turn, provides a mounting for a second block D which is movable toward *and from the other. Each block preferably consists of a suitableframe 5 -whereon is 1 carried a bell 6 having the contour required for engaging suitably with a hat crown.

- The lower portion of the fixed block frame is provided with a'transverse opening I .7 wherein is mounted .a cylindrical housing 8 which extends through a similar opening .in the movable block frame. From the fixed block frame on opposite sides of the housing are extended toward the movable block certain walls 9. having concave inner faces so disposed as to" provide between them and 50 the housing a guidew'ay in the form ofan annularspace 10 wherein may be slidingly .receiveda pair of bowed ribs ll-forming in effect acylindrical head. These ribs which against any rotative tendencies.-

depend from the movable block frame are so *shaped as to surround the housing except along its lower side wherein is formeda longitudinal slot 12. The lower rib edges are shown as straightened out to receive between them a plate 13 having a toothed u er edge portion which extends within t e ousing slot. This plate may be carried between the two ribs 11 as by means of one or more pins 14.. l y' Within the housingis a worm screw 15 adapted to co-operate with the teeth of the plate 13 so as to cause the movable block to advance toward or recede fromthe fixed block. At its inner end this screw is rested against a pin'16 extending transversely of the housing, the opposite end of theworm screw terminating in a shaft 17 which may be of reduced diameter. The screw is held fixedlywithin the housing as by means of a collar 18 which is pinned or otherwise made fast to the housing; this collar surrounding the shaft in such a manner as to receive end thrusts from the worm screw when the movable block is adjusted toward the other.

to facilitate manual rota:

It is preferred that the board A shall carry a plate 20 on which are markings indicating the size to which a hat Wlll be stretched-in each of the various positions of the movable block. A pointer 21 depending "from the movable block so asto terminate adjacent this marking plate serves to apprise i the operator of the adjustments tation by engagement of the plate within the housing slot 12 and also by engagement within the guideway of the head which depends from the block D. The distance of separation between the two blocks indicated in Figs. 1 and 2 is rather extreme, and in ordinary practice the depending head may be relied upon to steadythe movable block The present hat stretcher is advantageous "An operating handle 19 may beapplied to the shaft 17 so as tion thereof.

in many respects Its several components may be produced and assembled at small expense, and, whenever required, substitution of one part for another may be readily also extended within the guideway from one block toward the other and having a fast connection with one block, there being a slot extending longitudinally of the housing, screw means rotatably secured within the housing, and an element extended within said slot engaged by the screw means and connected with the movable block whereby the same is shifted toward and from the other with rotation of the screw means, substantially as described.

A hat stretcher in which are combined a pair of blocks, a slotted housing secured fast to one block and extended through the other, a toothed element connected with the latter block and extending in part through the housing slot, and screw means rotatably secured within the housing in engagement with the toothed element and adapted, when rotated, to move the block to which said element is connected toward or from the other block, substantially as described. 7

3. A hat stretcher in which are combined a tubular housing slotted for a portion of its scribed.

tive, rotation between the two blocks, substantially as described.

5. A hat stretcher in which are combined a pair of blocks each having a transverse opening in aligmnent with the other, means forming a guideway extending from one blockto the other, means on the latter block adapted for sliding movement within the from each other, a pair .of ribs depending from one block and bowed .to provide between them a cylindrical space, the edges of the ribs remote from the block being straightened and spaced from each other, a tubular housing having a longitudinal slot therein slidably extendedwithin the cylindrical space between the bowed ribs, :1. toothed element carried between the straight .ened edges of the ribs and extended in part through the slot of the housing, and screw means rotatably secured within the housing, the second block which forms a mounting for the housing having a guideway in which the ribs are receivable in such a manner as to prevent rotation .of one block with respect to the other, substantially as described.

7. A hat stretcher in which are combined two blocks movable relatively toward and .from each other, means forming a guideway extending from one block toward the other, means forming a head extending from the other block and slidably receivable within the guide-way, a slotted housing carried fast by one block and extended through the other, a .tootlied element connected with the latter block and extended in part through the slot of the housing, and screw means rotatably secured within the housing in engagement with the toothed element and adapted, when rotated, to effect a movement of one block relative to the other, substantially as described.

8. A hat stretcher in which are combined a base a block fixedly secured to the base, means forming a guideway extending laterally from the block and rested on the base, a second block having means extending therefrom adapted to be slidably received within the guideway, and screw means having operating parts connected with each block adapted to effect a relative movement therebetween, the guideway and parts associated therewith serving to prevent rotation of one block relative to the other, substantially as described. i

9. A hat stretcher in which are combined two blocks movable relatively to each other, screw means extending between the two blocks for effecting movement of one toward and from the other, and a mounting whereon one block is slidably carried havingla fixed connection with the other block, saidmount, ing being in the form of a housing wherein said screw means is contained in part, substantially as described.

10. Ahat stretcher in which is combined a pair of relatively movable blocks, tubular means fixedly secured to one block and extended therefrom through the other to problock whereby to move the same relative to the other block, substantiallyas described.
