Fig. 5 is a detion is of peculiar construction in that it is tached View of the card-clothed member equipped with card-clothing arranged at intervals to leave intervening air-spaces and adapted to act on the hideor skin, so as to take off the grain thereof and produce leather of the character known in the art as undressed kid, especially adapted to the manufacture of gloves. This cylinder comprises in its construction a hollow or drum-like core 16, the ends of which are closed by heads adapted to receive the shaft 17, to which the core is firmly secured and by which the entire dressing-cylinder is revolubly mounted in the framework of the machine in a manner similar to the abrasive cylinder of the machine disclosed in my former patent. On this core is seated a series of card-clothed members 18,which maybe either of wood or metal, and each member is notched, as at 19, at a point intermediate of its length. This construction of the member provides for bending the same at its middle to secure an angular shape and a crest 20 between the reverselyinclined portions. Each member-has its active surface formed by card-clothing 21, provided with the pointed pins or needles 21, and this card-clothing extends the full length of the member, so as to constitute the active surface thereof. The series of angular members are applied or seated on the core in spaced relation one to the other for the purpose of leaving air-spaces in the intervals between the card-clothed active surfaces of the cylinder, and said members are disposed in corresponding positions on the floor for the crests 20 of the members to lie in the same plane transversely to the cylinder, whereby the reversely-inclined portions of each member lie in parallel relation to the similar portions of adjacent members. Each member 18 and the card-clothing therefor are clamped or held on the surface of the core by the employment of a pair of clamping-strips 22 23, the same being disposed on opposite sides of the member and fashioned to embrace said member and its card-clothing. Each clam ping-strip is substantially Z-shaped in crosssection, so as to form a base-flange and an overhanging outer flange, as shown more clearly by Figs. 4 and 6. The pair of clamping-strips for each member and its card-cloth ing are arranged in reverse positions with respect to the member, so that the bases of the strips will rest upon the core, while the overhanging outer flanges thereof will extend over the top edges of the memberand rest upon the card-clothing. These clamping-strips are fastened to the core by screws 24,wl1ich pass through the base-flanges of said strips and serve to draw the same in a direction toward the core, whereby the outer flanges are drawn inward against the card-clothing, and thereby firmly clamp said clothing to the member and also clamp the member upon the core. It is to be observed that the pair of clampingstrips, disposed on opposite sides of the member, and the card-clothing thereof operate to hold these parts against displacement circumferentially on the core and to seat the parts firmly in planes radial to the axis of the core, whereby each member and its card-clothing are confined so firmly and securely that they cannot become displaced through ordinary service of the machine. At the same time one or both clamping-strips may be removed by taking out the screws to enable the attendant to take off the card-clothing when worn and to replace the worn card by a fresh card.
The members 18 and the card-clothing thereof are grouped quite closely around the cylindrical core; but at the same time they are spaced at intervals, so as to leave alternate air spaces or openings 25 between the active surface of the dressing-cylinder,which is formed by the card-clothing 21. The cardclothing conforms to the angularity or bend of the members, and the hide or skin is designed to be fed to the cylinder at the middle thereof, so that the central portion of the card-clothing over the crest 20 on each angular member will act first on the hide or skin. As the active surface of the angular member formed by the card-clothing conforms to the divergence of the member, the needle or pin points of the clothing will act on the skin not only to take off the grain and produce the desired finish on the surface, but also have a tendency to work the skin toward the flanks or edges thereof, thus making ample provision for the elimination of wrinkles from the skin, and obviate any tendency to cut or injure the skin in the operation of dressing the same.
The dressing-cylinder of my invention is driven or rotated at a comparatively high speed, and if it were provided with a continuous card-clothing the frictional action of the card on the skin would have a tendency to unduly heat the leather, and thereby cause deterioration thereof. This objection is overcome by the spacing of the members and the cards, so as to form the air-spaces, which alternate with the active surfaces of the cylinder. In the operation of the cylinder the cards act to take the grain off the leather, the series of cards acting successively; but as the leather is not exposed to a continuous action of the cards an opportunity is allowed for the leather or skin to cool somewhat in the interval between the frictional engagement with the cards therewith. The rapid rotation of the cylinder and the successive frictional engagement of the spaced series of cards with the leather give the latter a chance to cool and provides for the circulation of air, so that the quality of the leather is not inj ured by the treatment given thereto by my machine.
Changes within the scope of the appended claims may be made in the form and proportion of some of the parts, while their essential features are retained and the spirit of the invention is embodied. Hence I do not desire to be limitedto the precise form of all the parts as shown, reserving the right to vary therefrom.
Having thus described the invention, what I claim is 1. A dressing-cylinder for leather-working machines having its active surface formed by a plurality of longitudinally-disposed series of flesh-removing teeth, said series of teeth being separated by intervening spaces to permit a brief interval to elapse between each frictional application of the cylinder to the hide, whereby the lateral stretching of the hide is effected and its heating is prevented.
2. A dressing-cylinder for leather-working machines having its active surface formed by longitudinally-disposed series of flesh-removin g teeth disposed radially, each series of said teeth being angular in form and separated from the adjacent series by intervening spaces, whereby the hide is worked from the center toward the flanks to prevent wrinkling and is permitted to cool after each frictional application of the dressing-cylinder thereto.
3. A dressing-cylinder for leather-Working machines, comprising a core, a series of longitudinally disposed angular members in spaced relation on the cylinder, and radial flesh removing teeth distributed over the outer surfaces of said angular members.
4. A dressing-cylinder for leather-working machines comprising a core, a series of longitudinally-disposed tooth-retaining members extending continuously from end to end of the cylinder, independent means for conmachines having its active surface formed by radial flesh-removing teeth, said teeth being arranged in series extending from end to end of the cylinder, and said series having an angular formation the advance portion or crest of which is located at the middle of the cylinder, whereby the operation of the cylinder effects the lateral stretching of the hide.
6. A dressing-cylinder for leather-working machines provided with a series of longitudinally-disposed teeth-carrying members extending from end to end of the cylinder and having an angular formation, card-clothing located flatwise upon said strips and having a notch formed in one edge to permit said clothing to conform to the angular contour of the member, clamping devices secured to the outer face of the cylinder and serving to clamp the card-clothing and members to the cylinder,-and flesh-removing teeth disposed radially to the cylinder and extending from the flat outer faces of the card-clothing.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in thepresence of two witnesses.
