Inventor: TAYLOR CHARLES
Filed: 1903-06-27
Granted: 1904-04-28
Abstract: 14,266. Taylor, C., and Taylor, G. B. June 27. Driving -mechanism. - Relates to the lubrication of drive, conveyer, and similar power - transmitting chains, and especially to those used on pedal and motor - driven cycles and cars, the chains being of the type in which hollow or partiallyhollow connecting- pins a, Fig. 4, are used to join the links together. A lubricant container c, Fig. 1, is mounted on a lever e and has its closed end c<2> adjacent to the chain A to be lubricated. A layer c<3> of felt or other flexible material is attached to the end c<2>, and is wiped by the chain as the pins move past it ; a perforation c' permits the lubricant, which is preferably solid, to be forced out of the container by means of a screw plug g operated by means of a chain h, or by other means, by the rider. The lever e is normally drawn back against a fixed stop f by means of a spring e<3>, the lubricator being then out of action, but, by means of a rod e', the container c may be moved into contact with the chain. A small amount of the lubricant is passed to each pin, and is further moved into each pin by means of a metal tongue d which enters a recess a', Fig. 5, cut in the end of each pin. The chain is supported during lubrication by a roller or plain guide i, Fig. 1, which slides in the frame j, and is moved, by means of the lever i<3> and rod shown, to bring one of its surfaces opposite to the pin receiving lubricant from the opening c'. The container c may be utilized to carry a cleansing-fluid for the chain ; the guide i is then left in the position shown, so that one end of each pin is open as it passes the opening c'. A modified form is shown in Fig. 6 for lubricating a chain while stationary. The container c and yielding tongue d are carried by a lever m mounted on a pin m<2> on a lever n which carries the guide i. A tooth o engages between the rollers or blocks of the chain to bring the hollow pins into position to receive the lubricant. When it is required to cleanse the chain, a hinged piece q is swung into position to keep the hollow pins from touching the guide i. The piece d may be dispensed with. In another modification, similar to that shown in Fig. 6, four pins may be lubricated at once, but only one setting-tooth o is required. A supplementary lubricator is also provided for the pin connecting the two ends of the chain the guide for this lubricator being set back slightly to allow for the extra length of the pin.

Title: Improvements in the Method of, and Means for, Producing Ornamental Patterns on Pile and other Fabrics or Goods.
Inventor: DAVIES OSWYN ST LEGER
Filed: 1903-10-06
Granted: 1904-08-25
Abstract: 21,427. Davies, O. St. L., and Booth, J. Oct. 6. Designs on face, producing.-Ornamental patterns are produced on the face of pile or other fabrics by removing or partially removing the pile or nap at parts. According to one method, the parts of the fabric on which the pile is to remain are printed in an ordinary printing-machine, having more deeply engraved rollers than usual, with a thick gum or paste which may be the ordinary gum thickening used by calico printers. The gum or paste is then dried, and the fabric is guided partly round one or more internally-heated rollers by means of adjustable bars or rollers. The gummed and flattened parts are unaffected, while the unprotected pile is burned or singed away. Instead of the heated rollers, one or more heated plates may be used. The fabric is then washed or treated to remove the paste or gum, and is dressed or finished as required. Any suitable chemical solution or non-inflammable paste may be used in addition to, or instead of, the gum or paste, and coloured or other effects may be previously produced on the fabric. By varying the severity of the burning treatment, or by modifications in the gum-printing, the degree of severity of the burning of the pile may be varied in a piece. In another method, parts of the pile are depressed by printing on a thick gum under pressure, or by the use of a weighted engraved roller or plate, and the remainder of the pile is wholly or partly sheared or cut away by means of knives or cutters which may be of the kind used for shearing or cropping cloth. The invention is applicable to velvets, velveteens, and other pile goods of cotton, wool, silk, &c., or mixtures of these, and may be used in connection with flannelette to remove portions of the nap provided in the raising-machine. In this case, a gas singeing-machine may be used to remove the light unprotected nap. In the Provisional Specification, it is stated that the pile fabrics may be subjected to the action of a stationary plate or box or rotating roller internally or otherwise heated, and having the desired pattern in relief, or the singeing may be effected with the use of one or more suitable perforated pattern plates or rollers working in conjunction with a gas singeing- arrangement.
