certain that the quantity of metal in the bush or thimble, which has been passed through the link, shall neither exceed nor be deficient of the quantity required to fill the countersink completely when thus pressed. Q P Q P represent the two dies with the link between them, at the end of this operation the dotted lines being intended to represent the figure of the bushes or thimbles, and the countersinks with the steel pins through them; these steel pins are of the same size as the pins which are afterwards to connect the links together when forming the endless chain. C4 represents the link when bushed or thimbled in the manner described, and it is evident that the nicest accuracy must be produced with respect to the length of the bush or thimble thus fixed in the link, the size of the hole in the bush and the distance of the holes from each other. Of course every link in the chain must duly bear an equal share of the weight to be sustained. I desire it may be observed, by way of general explanation or specification of my said invention, that such invention consists in producing a link or links with its 'bushing, as represented at C 4, with those properties above described of being all exactly alike, both with respect to the distance and size of the holes, and also the shape of the link. Table 4 represents a front and profile view of a piece of the chain put together, where the links are placed alternately three and two abreast, but this may be variod as circumstances required, viz. one link or two, three ar four, &c. abreast, at the discretion of those who are to use the chain. In witness whereof, &c. Specification Specification of the Patent granted to JACOB BUFFINGTON, of the City of Bristol, Gentleman; for a new Method of straining or stretching (technically called habiting) all Kinds of Woollen Cloth for cropping or shearing, and for stretching or straining all other Kinds of Piece Goods. Dated October 30, 1804. With an Engraving. To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said Jacob Buffington do hereby declare, that my said invention is described in manner following; that is to say: To strain cloth, or any other stuffs that require to be strained, I secure the lists of the cloth to one edge of strong web by lacing or otherwise; the other edge of the web is made fast to a small rope or cord that passes through appertures in frames, so made as to suffer the web to pass freely when moved forwards, and to prevent the rope or cord from drawing out in the act of straining. In the margin of these presents is represented a frame, which answers this purpose; but the construction may be varied, if thought necessary, so that the principle object of the invention is adhered to, viz. to strain the cloth or stuffs from selvage to selvage, or list to list. By this means the operation of cropping, shearing, &c. is much facilitated, and the workman enabled to produce better work, and in less time than he could by any former method. DESCRIP |
