Application October 10, 1936, Serial No. 105,107
7 6 Claims. This invention relates to means for stretching to shape and holding in shape articles requiring such treatment, and has particular reference to improvements in means especially intended for shaping and holding uniform cap covers while the same are being washed and during drying 7 object of the present invention is to provide a cap cover stretching and holding means which is collapsible so that it may readily be inserted into a cap cover, and which, when inserted, is readily expansible to effect stretching and shaping of both the band portion and the crown or hell portion of the cap cover.
Cap covers are, of course, made in different sizes to fit caps of different sizes, and in this connection another important object of the invention is to provide a cap cover stretching and holding means which may readily be adjusted so that when it is fully expanded it may be any one of. a number of different sizes corresponding to any one of a number of different cap sizes, whereby cap covers of different sizes may be stretched the exact amounts required to fit caps of difierent sizes.
In stretching and holding a cap cover it is important that the stretching and holding means shall be effective to hold the cover against twisting, as otherwise the cover, when dry may not properly fit the cap on which it is used. Accordingly, another important object of the invention is to provide a cap cover stretching and holding means embodying a construction whereby it is effective to hold a cap cover stretched thereon not only against twisting but in all other respects properly shaped.
It also is important in stretching and holding a cap cover that the band and crown of the cover be supported in proportion throughout their length against sagging, as otherwise the cap may not be smooth throughout when it dries and difficulties may be experienced in stretching the cover to exact predetermined size. Accordingly, another important object of the invention is to provide a cap cover stretching and holding means which not only is adjustable-as to size in its expanded condition, but which, regardless of its adjustmentas to size, is effective to support against sagging, throughout its length, the band of a cap cover stretched thereon.
Further, the invention has in view to provide a cap cover stretching and holding means which is of simple, inexpensive construction, which is easy to insert into and expand within a cap cover, which is equally easy to collapse and remove from a cap cover without distorting the latter, and which, generally speaking, is thoroughly practical and thoroughly reliable and efficient in use.
With the foregoing and other objects in view, which will become more fully apparent as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.
In the accompanying drawings, wherein like characters of reference denote corresponding parts in related views:-
Figure 1 is a perspective view of a cap cover stretching and holding means constructed in accordance with one practical embodiment and shown in operative position within a cap cover.
Figure 2 is a top plan view showing a collapsed condition of the stretcher shown in Fig. 1.
Figure 3 is a top plan View showing a further collapsed condition of the stretcher shown in Fig. l to facilitate insertion and removal of the same into and from a cap cover.
Figure 4 is a longitudinal section through the stretcher as shown in Fig. 1; and
Figures 5, 6, 7 and 8 are views similar to Figs. 1, 2, 3 and 4, respectively, illustrating an alternative embodiment of the invention.
Referring to drawings in detail, first with particular reference to the embodiment of the invention illustrated in Figs. 1 to 4, it will be observed that the present device comprises a pair of segmental shells I 0 and H of nearly semicircular shape as viewed in plan, formed in any suitable manner from any suitable material such, for example, as rustless sheet metal, and conforming in cross sectional shape and curvature as viewed in plan to the normal cross section shape and curvature as viewed in plan of the front and rear portions of a cap cover in which they are respectively designed to fit. In other words, each section 18 and H comprises in the present instance a collar portion H of a height and of a curvature as viewed in plan substantially corresponding to the height and the normal curvature as viewed in plan of the front or rear band portion, as the case may be, of a cap cover it is designed to fit, and a crown or bell portion i3 forming an upward and outward continuation of the collar portion I2 and also conforming in cross sectional shape and in curvature as viewed in plan to the normal cross sectional shape and curvature as viewed in plan of the front or rear crown or bell portion, as the case may be, of a cap cover it is designed to fit, so that when the sections lii and H are placed within a cap cover at opposite ends thereof and are moved apart, normal shape is imparted to the cap cover.
For stiffening and maintaining the shape of the collar portions l2 of the sections ill and II said collar portions preferably are provided at their bottoms with inwardly directed flanges it. Similarly, in order to stiffen and maintain the shape of the crown or bell portions 23 of said sections l6 and ii, and, in addition, to provide rounded edges and cap cover top portion supports at the tops of said portions E3, the same preferably are provided at their tops with inwardly directed flanges l5.
To each side portion of the collar portion E2 of one of the sections it or H, at the inner side thereof, and suitably spaced inwardly from the related free end of said collar portion, is suitably hinged, as indicated at it, one end of a link element H which is of no greater length than the distance between its hinged end and the adjacent end of the collar portion i2 and which preferably is of substantially the same height as said collar portion. Conveniently and practicably these link elements, one at each side of the collar portion l2, may be formed from stiif Wire bent into rectangular shape as shown, but, of course, they may be formed from sheet metal or they may be of any other suitable form.
To the free end of each of the link elements H is hinged in any suitable manner, as indicated at E8, one end of a companion link element l9 which is formed from suitable sheet material and which preferably is of a height conforming as nearly as practicable to the height of the collar portions l2. At its free end each link element I9 is provided with a pair of outwardly or otherwise suitably directed tongues 2t, one adjacent to the upper edge and the other adjacent to the lower edge thereof, while formed in the collar portion i2 of the other section it or H, as the case may be, adjacent to each end of said collar portion and at points preferably spaced apart circumferentially thereof by amounts corresponding to the difference in cap cover sizes, is any desired plurality of pairs of slits 2! arranged to be selectively engaged by the tongues 29. Thus, by first inserting the sections ill and H into a cap cover and properly arranging said sections within the front and rear portions of the cover, and by then engaging the tongues 20 at the free ends of the link elements i9 in proper pairs of the slits 2i, depending upon the size of the cap cover to be stretched, while the link elements ii and it are disposed in obtuse angular relationship as shown in Fig. 2, all that is necessary to effect expansion of the stretcher and stretching of the cap cover thereon is to exert outward pressure against the hinged together ends of the link elements H and it. In this connection it will be noted that when the tongues 28) are engaged in the slits 2i the link elements ill and 88 provide toggle connections between the sections ill and H so that only relatively slight outward pressure against the hinged together ends of said link elements is required to effect a forceful separation of said sections l9 and H and consequent eifective stretching of a cap cover engaged on said sections. Also, it will be noted in this connection that the link elements ll and 58, as viewed in plan, are curved corresponding to the curvature of the collar portions l2 of the sections Iii and H and that, therefore, when said link elements are pressed outwardly until they lie against said collar portions E2 the hinged connections between their adjacent ends lie outwardly of straight lines drawn between their points of connection with the collar portions of the sections it and II, thereby locking said sections against relative inward movement until one or the other of the toggles is broken.
Of course, instead of providing pairs of tongues 26 on the free ends of the link elements l3 and corresponding pairs of slits 2i to receive such tongues, each link element 58 may be provided at its free end with only a single tongueof any desired height and single slits 2i may be provided to receive such tongues. In fact, any desired readily separable connections may be provided in lieu of the tongues 20 and the slits 2i. Preferably, however, the dual tongue and slit arrangement shown is used because the slits 28 do not noticeably weaken the collar portion l2 in which they are provided and because t -e tongues 25! adjacent to the topand bottom edges of the link elements 58, when engaged in the slits 2i, serve effectively to prevent any twisting of said link elements l8 relative to the collar portion l2 having the slits therein. In this connection. and as will further be noted, due to the material height of the link elements ll and l8, said link elements cooperate with each other and with the collar portions 92 of the sections l6 and ll effectively to prevent any relative twisting of said sections when they are held relatively expanded by said link elements. Furthermore, and as will further be noted, the link elements l8 span the spaces between the ends of the collar portions I2 of the sections ii] and H when said sections are held relatively expanded and constitute, in effect, continuations'of said collar portions, at the points Where otherwise spaces would exist between the ends of said collar portions, thereby effectively preventing any inward sagging at said points of a cap cover band stretched on the device.
When the device is not in use the sections it and II thereof may be nested one within the other as illustrated in Fig. 3 so as to occupy only a minimum amount of space for storage or other purposes; also, said sections may be nested as illustrated for facility in inserting the same into and in removing them from a cap cover. Moreover, and as is apparent, it is not necessary that the tongues IQ of the respective link elements it be engaged in corresponding slits at opposite sides of the collar portion 52 having said slits. On the contrary, the tongues of one of the link elements may be engaged in any selected slits adjacent to one end of the collar portion l2 having said slits and the tongues of the other link element 18 may be engaged in any selected slits adjacent to the other end of said collar portion. In this way, and by the provision of only a small number of slits adjacent to each end of the collar portion l2 having said slits, the device may be adjusted to fit practically any size cap cover within a relatively wide range of sizes.
Referring now to the embodiment of the invention illustrated in Figs. 5 to 8, it will be observed that the combination of elements is generally the same as illustrated in Figs. 1 to 4, but that a different form of toggle means is provided for connecting and relatively expanding the basic sections of the device. In Figs'. 5 to 8 the basic sections are designated as Ili ll and, as in the case of the Figs. 1 to 4 embodiment of the invention, each section includes a collar portion, designated as i2 and a crown or bell portion, designated as 13 To one of the side portions of the collar portion [2 of one of the sections It] or H at the inner side of said collar portion, is suitably hinged, as indicated at [6 one end of a link element H and to an intermediate portion of said link element is suitably hinged, as indicated at I9 one end of a second link element which is designated as W and which is provided at its free end with tongues 20 to be engaged in any selected pairs of openings 2 l provided at circumferentially spaced points in the related end portion of the collar portion I2 of the other section w or I l as the case may be.
To the other side portion of the collar portion 12 of the same section ill or H that carries the links Il w at the inner side thereof, is suitably hinged, as indicated at 22, one end of a link element 23 which, at its other end is pro- 7 vided with a pair of tongues 24 to be engaged in any selected pair of a plurality of pairs of openings 25 formed at circumferentially spaced points in the related end portion of the collar portion l2 of the other form W or H as the case may be.
The link elements W [B preferably are formed of wire as shown, although either or both of the same may be formed from sheet metal or any other suitable material. As shown, the free ends of the link w preferably are bridged by a strip 26 which not only braces the ends of the link but also serves as a stop for preventing the ends from passing completely through the openings 2 l when initially engaging said ends in said openings. The link elements Il 18 function in the same way and to accomplish the same purposes as the link elements 11 and [8 of the Figs. 1 to 4 embodiment of the invention, but, as distinguished from the Figs. 1 to 4 embodiment of the invention, the outer or free end portion of the link element Il constitutes a handle to facilitate closing andopening of the toggle comprised by the respective link elements H Ill and only a single toggle is employed, the link 23 constituting merely a separable, adjustable connection between adjacent end portions of the collar portions I2 of the forms at one side of the stretcher. In this latter connection it will be understood, of course, that according to the Figs. 1 to 4 embodiment of the invention only a single toggle may be provided at one side of the stretcher and that a link similar to the link 23, or any other suitable means, may be provided to separably, adjustably connect the forms together at the other side of the stretcher.
