Description
UNITED STATES ATEN'I FFICEO CHARLES F. OROGKETT, Oh NEWARK, NEWV JERSEY.
IMPROVEMENT lN MAKING SHEETS 0F LEATH ER FROM CURRIERS SHAVINGS OR BUFFINGS.
To all whom it may concern:
Be it known that I, CHARLES F. OROCKETT, of Newark, in the State of New Jersey, have invented a new and useful Method of Making Sheets of Leather from Ourriers Shavings or Buffings, of which the following is a full, clear, and exact description.
The object of myinvention is to render use ful the curriers shavings or buffings made in the process of manufacturing patentjapanned leather, which shavings or buftings have been heretofore thrown away or burned as useless; and my said invention consists in taking such shavings or bnffings while in a moist state, overlapping them to the thickness and size required and uniting them with some suitable cement, and then subjectingthem to pressure, by means of which I am enabled to produce sheets of leather of any desired size and thickness. I take the buflings orshavings produced by curriers in currying leather, particularly such as is intended for making patent japanned leather, and if they are not sutficiently damp at the time I soak them, so as to be soft and pliant, and in that condition 1 arrange them by lapping on piece after piece until the required thickness and size of sheet are obtained, taking care, as I arrange and lap them, to coat the several surfaces which are to come in contact with what is known as india-rubber cement or other equivalent cement, and then I subject the whole to a suffr cient pressure not only to cause the cemented surfaces to be brought in close contact and to insure their union, but at the same time to reduce the whole as near as may be to a uniform thickness." This pressure may be applied by placing the cemented sheet between two plates and inserting such plates into any suitable press, and there letting it remain until the several pieces have become thoroughly united by the cement. I have also applied the required pressure by rubbing the surface with what is called the curriers glass, taking care not to curl'up the overlapping edges, which are usually very thin. The surface is to be properly glazed or grained in the usual manner, if desired. In this way I havesuccessfully produced from these shavings or buffin gs, heretofore wasted, sheets of leather of any desired size and thickness and possessing great strength.
I do not wish to confine myself to any particular kind of cement, although I have found india-rubber cement to answer the best purpose; nor do I wish to limit myself to the mode of applying pressure, as any mode will answer the purpose which will compress the sheet and lay the edges smooth, although I have produced the best result by rubbing and pressing the surfaces with what is known as the curriers glass, which has the effect at the same time of glazing the surface.
- What I claim as my invention, and desire to secure by Letters Patent, is-
Making sheets of leather of any desired size and thickness of curriers shavings or buffings bylapping and cementing them together while in a moist state and then subjecting the mass to pressure, substantially as and for the purpose specified.
