Leiters Patent No. 89,789, daad. May 4, 1869sl imnovnn M Acia'rm: FORBUFHNQWHITENING, GtAssING, POLISHING, AND sToNING LEATHER. Y v y.
` Theschelule xfeferred to in these Letters Patent and making part f the Same- To` all whom it may concern "Be it known that I, ALBERI) W. PRATT, of Salem, n
inthe county of Essex, and State of Massachusetts,
have invented a new and useful4 Improvement in Machine-for Manufacturing Leather.; and-I do hereby declare the following to, be a full, clear, and exact description of the same, reference` being had to the drawing accompanying this specification, and making part of the same.
In the drawing-"- Figure l represents a front elevation of the naa-- chine. i
`Figure 2 is a -longitudinal vertical section. on thev inder,andk making the seat on which the tools are fastened at an acute angle with a-tangent of the cylinder, projecting inward, and revolving'said cylinder over an elastic bed, so `arranged that it may be depressed, but is prevented from rising so high as to touch the cylinder.
To enable others skilled in the art to make and use my invention, I will `proceedto describe its construction a nd operation. In thedrawi'ng` f y F F represent the frame, made of wood. V represents 'a-shaft, running in the boxes B, fast-v ened rigidly `to the `frame. f V
`On the shaft V, and outside 4of the frame Fa tight and loose pulley, O Cl, are placed, to which power is applied by means of a belt. i n
In the centre, between the sides of the frame F, another pulley-wheel,\D, is Afastened to the shaft VI "In the peripheryvoffthis wheel, a series `of slots,
i O O, is cut atan angle with the shaft V, and extending inward, at an acute angle, to a tangent of the wheels, forming a seat, L, on which are fastened 'the knives E, and other tools used inthe machine.
rIhe knives, steels, or glasses, `are formed fiat and' straight, with then-edges rounded, to iit the shape of the slot `at the periphery. f i
i Underneath the pulley Dare placed the standards X X, supporting a rectangular frame, N, `which guides and supports thebed T.
This bed, at the front end, rest-s on the-bolt Gand ,end is supported by a pivot'on each side.
Ilhe bolt G screws up through the nut K, by which the bed is raised or lowered to suit the varying thickness of the leather.v Y,
The nut K-is fastened to the bed, so as to prevent the bed rising only so high as needed.
The bed is made more or less elastic in its action by compressing or loosening the spring S, with the thumbnut P.
This spring S is supported by the bar U, fastened tothe standards X X, and holds the bed and leather against the tools in the revolving cylinder D, and is prevented from lifting them too near the cylinder by the headof the bolt G coming against the under side of the bar U. i y
By unscrewing the bolt G, the bed is brought nearer the cylinder, and the leather cut to the desired surface. The `manner of using my machine consists iny giving the cylinder a rotary motion of one to .two thousandY l,turns a minute, and placingthe leather upon the bed under the wheel, andI moving it aboutuntil the desired surfaceis obtained.
` When my machine is used for buing or whitening leather, knives are fastened to the seats in the revolving cylinder, and are so set or Vadjusted that the cutting-edge extends beyond the periphery of the cylinder, but the least possible distance to make a cut.v No throat or opening is left in front of the cuttingedge of the knife, but the shaving or dust abraded from the leather is thrownoif from the cylinder by the centrifugal forceoi-the revolving wheel, in connection with the angular shape of the cut, which `drives the shaving to the side of the wheel.
When I` use the machine for glassing, polishing, or
.stoning out leather, a' tool, of glass, steel, or other material, is fastened to the tool-seat, which has a rounded edge, curved to fit the periphery of the wheel, and set or adjusted so that the tool will extend out beyond the periphery of the wheel, from one-sixteenth `of an'inch, more or less, as desired.
.chine is for buing and whitening leather.
Machines are now in use which perform the operations of glassing and polishing, but no. machine is in practical use which will satisfactorily whiten and bui leather; and in accomplishing this result the' knives do not act so much as cutters, as by their abrasive action, which, under a high speed of the cylinder,
takes olf a shaving in the `form of dust, and leaves the leather -in exactly the right condition.
In performing the various' operations of glassing, Y
polishing, cr stnning out, the action of the'machine upon the leather is entirely different from any machine now in use, particularly those machines in which a reciprocating arm carrying the tool is used.
In those machines the tendency is to harden and compact the leather, which, for upper leather, is very undesirable.
In this machine, the action is to soften and make.
it more supple, and t it better for making up and wearing.
Having thus fully described the nature of my invention,
What I claim as new, and desire to secure by Letters Patent, is
Placing the knives or toolsused in this machine at an angle with the shaft of the revolving cylinder, in combination with forming the seat to which the knives or tools are fastened at an acute angle with a tangent of' the periphery of the cylinder, projecting inward.
