5 Claims.

. This invention has to do with the initial preparation and conditioning of raw animal pelts and skins for ultimate marketing, and has as an object to provide convenient and efilcient means for stretching and supporting rawpelts during drying and curing thereof. A v

further object of the invention is to provide improved means quickly and conveniently insert able and extensible within a pelt to smoothly extend said pelt andhold itfin stretched condition during drying and curing.

A further object of the invention is to provide an improved arrangement of mean for thecirculation of air Within and about a stretched pelt. Afurthe'r object of the invention is to provide improved means in a pelt stretcher operable to quickly and positively extend and retract the stretcher relative to a pelt.v i A further object of the invention is to provide animproved pelt stretcher that is simple and inexpensive of manufacture in such sizes as may be best adapted ior use with pelts from specificanimals, which i compact, light in weight, and readily transportablawhich requires no tools or special appliances for itsuse and operation, and which is highly efficient in the accomplishment of theends desired. I k

My invention consists in the constructionyarrangement, and combination ofelements hereinafter'described, pointed out in my claims, and illustrated by the accompanying drawing, in w h. l Figure 1 is an elevation of, the improved stretcheras retracted for insertion within a pelt. Figure2 is a view similarto Figure 1 illustrating the stretcher as laterallyextended orexpanded for stretching of a pelt, certain surface portions being broken away to disclose otherwise concealed construction. Figure 3 is an edge view, partly in section, taken on the indicated line 3-3 of Figure 2. Figure 4 is a cross sectionjtaken on the indicated lined-4 of Figure 1. Figure 5 is a cross section taken on the indicated line 55 of Figural, Figure 6 is a cross section, taken on the indicated line' 6-6 of Figure 1. fragmentary, detail elevation, partly in section and with certain portions'broken' away to conserve space, of the stretcher-expanding member employed inthe improvement. I .In the construction of the improved 'as. shown,the numerals Hl'and H designate substantially identical, complementary board elements, preferably formed of wood or equivalent readilyeobtainable, light weight, substantially rigid, and easily worked material. Each of the Figure 7 is a stretcher,

elements In and H is relatively long, fiat, narrow in proportion to its length and thin in proportion" to its width, and is tapered from a relatively wider base to a somewhat narrower tip end. Long margins of the'elements l0 and II are preferably straight and said elements are arranged to be assembled with their inner, adjacent long margins parallel and their outer long margins conse quently converging from the base and toward the tip of the assembly. Tip portions of the elements In and II have their outer edge margins curved or inclined inwardly into relatively-sharper convergence to provide a somewhat pointed end adapted to facilitate insertionof the assembly within a pelt, and each of said elements In and II preferably terminates at its tip end in a longitudinally projecting point l2 adapted to engage in a nostril of the pelt, said points I! being closely adjacent when the device is retracted as shown in Figure l and being laterally separated when the device is expanded as shown in Figure 2.

The board elements In and II are maintained in the desired relationship and associated for relative lateral movement in any convenient or desired manner, means suitable for such purpose being illustrated as comprising slats I 3 transversely of and overlying opposite sides of the element wider or butt ends and secured to the element [0, a transversely-disposed slot I4 intersecting the wider end of the element ll between the slats l3, and a pin l5 fixed in and extending between the free ends of the slats l3 in traversing relation with the slot [4, a relatively-deep recess I6 in and opening laterally through the inner margin of the element I I adjacent and spaced somewhat inwardly from the tip end of said ele ment, a U-shaped yoke l1 fixed at its open end in and to the inner margin of the element ID to project laterally from said element and position its closed end for slidable reception within the recess I6, and a pin i8 fixedly engaging through and adjacent the inner marginof the element H to traverse the recess [-6 between the arms of the yoke I1. As will be apparent, the arrangement of means just above described serves to maintain the elements It) and H, in coplanar relation and against longitudinal relative displacement, while permitting limited lateral movement of one of said elements toward and away from the other.

for the application of forces operating to stretch Lateral separation of the elements l0 and H" of the elements l and I l and the shaft portion of said member at the butt end of the stretcher extends freely and slidably between the spaced slats l3 and projects outwardly beyond said slats a considerable distance, while the other .end .of said member shaft portion extends beyond the yoke l1 and is provided with a laterally-opening,

longitudinal slot disposed to accommodate and slidably embrace said yoke so as to permit limited longitudinal reciprocation of the memher l9 ,relative' to said yoke. The tip endof the member 1.9 is expanded or enlarged laterally to form a head 2| whereof the side margins con- -verge, at equal degrees of inclination toward the tipof the'device, to meet in a sharply-acute point on the longitudinal medianline of the assembly, thus providing-a symmetrically-disposed lwedge on the tip-end of said member, and inner side margins wof the elements .10 and H between theposition'of theyoke I1 and element tipends arelnotched and recessed .toconform with .and fit closely about theoutlineof the head 2| when said elements are moved laterally into engagemerit of their inner margin straight portions against .the member !9 shaft margins. Similarly,.-a-n intermediate-portion of the member I9 is extended laterally and marginally contoured to form a symmetrically-disposed second wedge or cam-n22 positioned about half way between the head 2| andthe ,butt end of :thedeviceand presenting-side margins converging toward the tip end ,of the device at substantially the samedegree of inclination as characterizes the converging-,marg-ins -of .the head 2|, and corresponding portions-of the element inner ,margins are shaped to,-accom1nodate wandrfit closely about the wedge ,22 when the elements of the assembly .are in the positionshown in Figure 1.

,As will be clear from the foregoing, the elements ill and H are held in coplanar relation and associatedfor limited relative lateral travel .bymeansofthe slats l3, yoke l1 ,andpins lfiand 18, while the ,member l9 isheld in ,positionbeitween said elements and mounted for limited longitudinal rtravel relative thereto by means of said =slats l3 and yoke I]. In the use of the device, the member 49 .is moved to the limit of its range-of traveltoward the .butt end of the device, whereby .the head .21 and wedge .22 of said member are brought into .full registration with the recesses or notches .formed for their accommodationlin the element inner margins, whereupon the elements 1.0 ,and H maybe approached later- ;ally until their inner margins engage with and against corresponding margins of the member '1 9 land the v.deviceis then retracted to the position ,of felements.shownin Figure 1. With the stretch- .er, retracted to its minimum lateraLdimension, apelt is telescoped over the tip end of the device and drawn therealong until fully extended thereon,.,with the nostrils of the pelt preferably engaged ,by the points [2, whereafter, holding the stretchersubstantially vertical, the projecting end t me member 19 may be tapped against any ,suitable firm object or surface and said member thereby shifted longitudinally of the device and toward the tip end thereof for wedging action of the head 2| and wedge 22 against and for laterally separating effect between the elements [0 and H, such action tending to shift the elements of the device to the relative positions shown in Figure 2 and thereby exert effective stretching tension interiorly of the pelt. The angle of inclination of the wedge or cam surfaces is so selected as to provide that friction between the engaged surfaces will hold the member IS in its shifted position for maintenance of stretching effect upon the pelt, thereby eliminating the necessity for any other means for fixing said member 19 in its shifted position. After the pelt has. dried or cured to the desired extent, the member I9 is reversely shifted to permit the elements 10 and ll to again approach laterally, and the thus-loosened pelt may be slipped freely and=easily over the tip end. and away from the device.

The device thus far described is operable to mount and stretch a pelt and. presents novelty of structure and operative relationship of elements for such purpose, .but the invention .presents additional novelty in the provision of means for the positive circulation of air within and through a pelt stretched on the device, such air circulation serving to facilitate and enhance proper curing and drying of the pelt. Each of the elements [0 and H is intersected by a plu ,rality of relatively-large holes or openings 23 spaced apart inany suitable arrangement to open through the parallel faces of said elements, and the head 2| and wedge 22 of the member 19 .are similarly intersected by correspondingly-disposed holes or openings 24. A .bore or passage .25 formed in the thickness of the element communicates between each of the holes 23 and the space between the element innerlmarginand the adjacentmember I9,.so that when the stretcher is xpanded, as shown in Figure .2, air may pass freely between each of the holes .23 and the channel open between the member 19 and .elements l0 and ll, even though said holes .and channel may be covered by a pelt. To insure that air may circulate longitudinally -of the device and through the channel above mentioned, longitudinal rabbets 26 are formed in the inclined side margins of the head-2l and wedge 22, so that a continuous passage longitudinally of the assembly is provided whenever the member 19 is moved to laterally separate the elements Ill and I I. As is clearly shown in Figure '7, the holes .24 intersecting the head 2| and wedge .22 com municate through suitable bores 21 with the rabbets 26, thereby providing for access of air to all major portions .of a pelt interior during stretchingand drying of such pelt on the device.

Since many changes, variations, and modifications in the specific form, construction, and arrangement of the elements shown and described maybe had without departing from the spirit of my invention, I wish to be understood as being limited solely by the scope of the appended claims, rather than by any details of the illustrative showing and foregoing description.
