Abstract: 7017. Byers, C. A., and Abbey, E. F. March 26. Machines for making. -Relates to brushmaking machinery and especially to machines for making brushes with solid backs, and has for its object to position a brush block automatically and in accordance with a previously-designed system, either for the insertion of the bristles or for the formation of the sockets for the reception of the bristles. The invention is shown in Fig. 1 in connection with a filling-machine C of the kind described in Specification No. 7498, A.D. 1886. The block is placed between an adjustable pair of clamps E, which are pivoted to a swinging frame F provided with rods F<1> adjustably mounted in trunnion blocks F<2>, which are themselves journalled on one end of a longitudinallymovable frame having shafts G<1> adapted to slide longitudinally in bearings G<2>. By this means, while the block carrier may be adjusted on two centres at right-angles to each other so as to vary its angle with relation to the inserter, in its movements towards and from the inserter it moves in a definite line. The block carrier is moved to and from the inserter C by a centering and advancing point H adapted to engage in apertures in a plate I secured in the rear of the clamps E ; these apertures correspond with the sockets in the brush block. The mechanism for effecting this motion is similar to that described in the prior Specification, but means are provided for ensuring the effectual disengagement of the point from the plate I when the latter has to be adjusted for the insertion of a tuft in a new or different socket. In order to adjust the angular position of the block carrier, it is provided with a shoe M, which is guided on a track L mounted on a sliding frame L' so that the block carrier rises and falls with the track L and moves transversely by the movement of the frame L<1> on its support N, these movements being effected by lever-mechanism terminating in rollers p<3>, L<12>, which bear, respectively, against two pattern cams indicated by dotted lines in Fig. 1, while one of them is shown separately in Fig. 6. The cams are operated by ratchet and pawl mechanism similar to that described in Specification No. 23,658, A.D. 1900. The cams are of a size sufficient to permit of the making of a brush by one rotation, and stop mechanism, Fig. 10, is provided to bring the mechanism automatically to rest at the completion of a rotation. This mechanism, which is interposed between the driving-shaft B and the cam shaft Q, comprises a projection R mounted on the shaft Q and having an inclined face adapted to move longitudinally a rod S provided with an inclined projection T, which, when pressed toward the driving- shaft, moves a spring pin T<1>, mounted in a disc T<2> keyed to the shaft B, out of a recess T<3> in a sleeve rigidly connected with the driving-pulley T<4>, and thereby stops the mechanism, which is started again by an attendant who pulls a rod S<3>, whereby the pivoted end S<1> of the rod S is moved away from the projection R, the latch S<5> is raised, and the spring S' forces forward the rod H and disengages the projection T from the spring pin T<1>. With the pattern cams shown, the starting and stopping points are in proximity so that, as indicated in Fig. 7, the course traversed by the tool terminates in a socket adjacent to that which constituted the starting point.
