and drying of skins or hides after being dyed or similarly treated and its object 1s a construction of stretching board or apparatus whereby the skins or hides may be stretched more uniformly. and to a greater extent than heretofore. At present the skins or hides are nailed to a board, the;

operator distending them as much as possible by hand as the nailing proceeds. Owmg Specification of Letters. Patent.

however to their irregular sha es, and owing also to the stretchlngbelng (one by hand,

the skins or hides are not always equally distended and the amount of stretch is not what it should be.

According to this invention .the stretchtively fixed and relatively movable partsi These latter are adapted to be adjusted away from and toward the fixedparts, and prefer ably by such means as will afford a gradual and powerfulforce. To these movable parts are secured by their edges the skins or hides to be stretchechand when the parts are separated the skins orhides are stretched and held stretched la a manner whlch insures;

of an even distentionof all parts of the skin and a degree of stretching greatly in excess of that obtainable by hand.

between two movable parts, and one board will be designed to hold several skins.

y a are two iurther parts which, as hereinafter To the fixed part btop and bottom is secureda bracket 9 wherein is mounted a spindle or rod in, the rod being freeto rotate but incapable of moving endwise. At

and near each end the rod is screw threaded and while the thread at one end 15 left handed the thread at the other end is right handed. To each of the movable parts a, a top and bottom are secured brackets 41, 71 and in one with each bracket is a tubular boss This boss, which virtually forms a nut, is screw-threaded internally to receive one of the screwed parts of the rod 71., the screw thread of each boss agreeing with the thread of that part of the rod with which it engages. Upon eachrod and lyingbetween the forks of the bracket 9 is a hand wheel by which the rod may be rotated to right or left. member 0' is supported at each end by fixed steel joists Z, the ends of such upper member being reduced to form shoulders and the face which bear against the joists being metal-faced to insure of the boards being readily moved along the joists. The several members (a), (a (0), (0 are in the form of narrow boards, the members ('c'), (0 beingwhat may be termed fcarr1er boards. The. parts f, f are in the form of short sectional. boards.

. In proceeding to fixa dyed skin or hide to the board for the purpose of stretching and drying the same, the movable parts a, a are caused to lie at theirshortest distance apart, as shown. The skin or hide is then nailed or otherwise secured by its edge to the said movable parts and the fixed parts as shown by dotted lines, the neck part of the skin being preferably arranged 1lowermost, so that the skin will hang naturally downward and be easily manipulated. When the skin or hide is fully secured to a 110 hand wheels/l; are each rotated in a direction which causes the parts a, a to sepa-U the board and ready to be stretched, the

The upperlongitudinal fixed rate, thescrewed rods and bosses affording a very gradual distention of the skin or hide until it is ,fully stretched. The limit of stretch will be determined either by the operator, or by the slots a When fully dis--- tended the skin or hide is left to dry, which takes place in the usual way. V o I To remove the skin or hide after drying, the nails are removed, when itwillbe found that theflskin or hide is'considerably larger than when stretched by hand. To makeready for the next skin or hide therods i are rotated in a direction which serves to causethe movableparts a, a to again come to their normal position. To provide for;

the" neck part of the skin vor hide being: s stretched proportionately tothe body part, thegparts. f, f are m'ade movable, but in stead of moving with the parts a, a as soon as these latter begin to separate, they 5 move only after thesaid parts a, a? have:

completed a portion of their movement. For this purpose, the-parts a, a are each; provided with a slotted plate m which en gages a fixed pin or stud n on the part f or 1 tively to the slot that not until the parts 7 next to it, the stud being so placed relal a, d have done a portion of the stretching,

'0 by, bolts oandlock nuts 70 and also to the fixed part b by dowels 9,. these latter being,

adapted to slide in dowelfholesformedin p the edges of the part b; The'openings r be: tweenthe parts a, a and 'bare intended to.

insure of the operator always nailing the skins t'oi the parts a, a in about the same position. The spaces between part b and I parts a, a opposite the members 0, 0 may be filled in to afford a level surface.

In the arrangement. shown in Figs. 2 and 23a right and left handed screwed rod ,6 is used which extends down behind the fixed part Z) of the board, and at points near each .end is fitted with nuts 25; To each of these nuts are :pivotally connected short links t which, in turn are pivota'lly connected to rods t workinggin guides at fixed t-o'the members 01, c? and connected to brackets u on the parts a, a By the rotation of the screwed rod t, the nuts approa h or recede I from each other and. thereby, separate or drawrtogether the parts a, a of the board,

In Fig. 3 only the part a is movable and the part 72 is dispensed with, the stretching,

being done by adjusting "the movable part away from 'the fixed part a. In this ar .rangement the screwed rods' have a right (or left) hand thread only, and if desired one rod is rotated by an vendless cord or chain fromtthef other; Forstret'ching. the neck m of the an the parts f, y will be-inovable in varying degrees, thepart f being connected to the part a by a studm, and slottedplate m and thepartf being con nected to the part f by a stud n and-slotted plate m' so that afterthe part a has partially stretched the body part of the skin .or hide the part f moves to partlystretch I the neck part, after which the part f moves to complete the stretching operation:

In Fig. 4:, the fixed part b is arranged at I say the end of theboard, or at a pointother than between the parts a, a The-screwed rods '0 are each mounted in a bracket 1) and held against endwise movement by collars o Eachrod-is fitted with a wheel w at oneend and the right and left handed screwed parts respectively engage the, like screwed bosses of brackets 013, ct.- The parts f,it are either fixed or adjustable as inFig. 1. s

In Fig. 5 the improved board is shown, with the parts a, a and Z) arranged horizontally, instead of vertically, and the memj bers c,'0- arranged vertically instead of h'orix g zontally. The rods 72 and brackets 9, 2', '2' are arranged on the face of the'board, but they may be arranged on the edges of the ends otthe said parts as 1n f Fig. 1. The two rods may also have pulleysf a and the rotation'of one may serve, through the medium of anendless band or chain, to rotate the other. In this-example of-theinvention the series of skins or hides to be stretched will usually require to be stretched j all at the same time. The parts 7'', f willfl be omitted and the spaces filled by further fixed parts extending from the to the member 0 'What I claim is-':I
