Be a known that I, Ammin 1am Mm,

, citizenof Germany,sub'ject of the King of.

Prussia and Emperor' of Germany, residing at 70 -H6chsterstras'se, Frankfort-on-the- Main, in the Kingdom of'Prussia and Empire of Gen'nanyy have invented a new and useful Machine for Dressing, Stretching, and

Otherwise Treating- Skins, Hides, Leather, 14)

. specification.

and the'Like, ofr which the following is a The subject-matter of my invention is an improved machine for dressing, finishing,-

stretching orrotherwise treating skins, hides, leather and the-like. p I

Oneobje'ct of the invention consists in fo fithetables' carrying the skins or hides and on theztwofjsifdes of the tables in symmet i-.

cally slantihg directions relatively-to the c i-' rection' of the 'table motion, saidslantingly jam-aged rollers lying in or approximately I d v in the lrections OfihQdiflgOIlfilSrbBtWGGIl the direc' oniof the motion of the tables andthe 1line, ;perpendicular to this direction, in such a manner that each pair of slantinglyan ranged rollers forms an angle opening-in the direction 'of the table motion.

A further object of my invention is that tli'e woi king ribs of each of the slanting roll ers run spirally in a manner known in itself toward. the ends of the roller from a plane at right angle tothe axle of rotation of this roller, this plane being so located in each instance that it'lies exactly or approximately I parallel to the central line of the apperta ing foot portion of the skin hungover t e moving table and coincideswith this=perfectly or approximately when the skin passes. By means of this arrangement it is possible Ito dress,;'stret ch" or otherwise treat the less united, loose or freely pendent parts'of the skin, namely the footand head'parts, intheir natural 'directions'of growth, so that folding and wrinkling of these parts of tlie hide during the dressingor stretching operation is avoided.

responding'to the changing size and shape of the hides or skins whiehnr'e to be treated it is important to arrange at least the one "of each pair of-slanting rollers displaceable inthe direction of its axis of rotation. 66

Otherobjects of my invention will be seen fromthe following description and claims in connection with the annexed drawings.

One constructional form jOf the machine is represented by way of example in the accom e5 panying drawings, Wherein Figure 1 is a front elevation, 2 is a vertical transverse section in the plane XX in Fig. 1, whereas Fig. 3 1s a crosssection through one of the rollers on a larger" 70 scale.

Referring to the drawing, the conveying tables or plates 2,- over which the skins or hides 3 are hung, are suspended movably on endless chains 4, in the. usual manner in the frame 1; the chains are placed around I wheels 5 and are driven with the intermediary ofthe toothed gearing 7, 8, 9 by the belt-pulley 6. In the illustrated form of the device three conveying tables are arranged so driven bythe endless chains, but of course four or five or another number of tables may be provided. The direction of motion of, the endless chains 4 and conveying tables) is indicated by arrows'in Fig. 2.

In the illustrated example, four obliquely disposed I'OllGIfSiLIfQ'PI'OVldGd which are arranged in pairs ,with the members of veach pair'on opposite sides of the path, of the tables-2. The front rollers fl'and of 1 each pair are seen in Fig.1,while in F1g. 2 the front and

rear members

11, 11 of one pair are indicated. Each-pairofsaid rollers (10 and .11) is arranged symmetrically slanting nearly -:in the direction-ofthe ding -9 5 onals between the direction of-fthe motion ofthe tables and the line perpendicularl-ito.

that direction, so that both rollers offea'ch' pair form an angle opening in -th'e direction of the motion of tables;

Belowthe slant rollers

10 and 11, which are locatedat'an' angle one to the other, are arranged inadd1 tion on each side of-thefpath of the'plates or tables horizontal rollers 12 and 125 The" rollers situated-at each 'side' of the path of the plates afe journaledina frame 13 and. 13, respectively, movable in the frame 1. The two, frames 13 and 13 are pressed toward one another 7}. e. toward thepat-h of the plates by'springs 15L and lit; -In the 11s 12 isrotsitedcorrespondihgly by thei wheel ,19, whic h meshes with the t flied wheel 8, sprocket wheel 16, chain flF and the sprocket wheel 18, so that the rollers-'12, and 12 rotate in opposite directionsfa's "will'be' readily understood. The slant roll'ersf arranged on both sides of the of theplates 2 and ;at an oblique angle to; the direction of motion of said plates are driven in this constructional .form from the"

horizontal rollers

12 and 12*, the slanting rollers located to the rear in the view shown of which only the one, 11, is ivisible in Fig. 2, being driven by means of the chain 20 from the shaftof the front roller- 12 and the front

slanting rollers

10 and 11 being driven by means of the chain 20 from the'rear roller 12. The horizontal ,{:"the rollers ofthe other pair because

onthat shafts

21 and 21* are coupled with the

chains

20 and 20 and, impart their motion by'means of

bevel wheels

22, 23 respectively to the slanting rollerswhich consequently rotate ini the direction of the arrows shown on them As is clearly shown in Fig. 1, the

rollers

11 and 11 of one pair are longer than side on which the rollers 11 are located, I

arrange the head of the hide and consef quently the hide'eXt-ends farther toward that side of the machine than toward the opposite side thereof. Further, as clearly shown in Fig. 1, the ribs on the slant rollers also run spirally from lines or points 2 1, situ- II ated between the ends of the rollers, toward the two ends, or in other words the spirals ofthe slant rollers or cylinders are divided ,fon=a line intermediate their ends, said dividgvg linenbeing arranged .in such a manner that it fwillbe as exactly as possible parallel 45.

to the:--.cen'tral line of the appertaining foot or claw portion of the skin hung over the table. The smaller rollers 10. are mounted displaceablyontheir axles 25. For raising.

by which rhomboidal figures are formed and lowering the rollers .10 there is provided a chain 26 guided overa sprocket wheel provided with a hand-wheel or crank 27, whereas the other end of the chain loaded by a counter-weight 28 slides in a guide 29. The construction of the rollers will be readily understood from the enlarged cross-sectional view in Fig. 3. They comprise an ordinary iron pipe 30, on the periphery of which spiral, angular, metallic strips 31 which may consist of iron, brassqor the like, are at- 'tached by rivets 32. It is preferable to pro- 'vide near the central lines 24: between the -.spirally wound strips'31 short cross-pieces in addition, as clearly shown in Fig. 1; 1 Owing to the arrangement of such cross-pieces,

skins 3 are hung in such a tables 2 that the central l1nes ofthe claw rollers. is improved. By the rollers being made hollow they are of comparatively small weight, so that their displacement'on theiraxles isfacilitated.

When my machine isused the hides or osition'over the parts register as exactly as possible with the. central lines of the rollerslO, 11 when passing the slanting

rollers

10, 11. In order to.

near each central line 24 the action of the obtain this according to the diiferent size of the skins to be treated in each instance the rollers are adjusted correspondingly by means of'the hand-wheel or crank 27'. The

inachine'may also be arranged horizontally.

Some or all the slanting rollers may be 'made displaceable axially by optional means i and I have shown them all so displaceable.

Having now particularly described: and ascertained the nature of my s'ald invention and. in what manner the same is to be performed, I declare that what I claim is 1.- In a machinefor dressing, stretching and otherwise working skins, hides, leather and the like a frame, tables for the skins movably arranged in'said frame, rollers with working ribs rotatably arranged in said frame on both sides of the path of the tables and parallel to them, said rollers on bothsides of said path being arranged in pairs in symmetrically slanting directions relatively to the direction of the motion of the tables, theslanting rollers of each pair forming an angle opening in the direction of said motion, and means for displacing one of each pair of rollers axially.
