Abstract: 14,199. Beauregard, V., and Gooding, C. S. April 5, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. India-rubber, cutting.-Relates to machines for cutting curvilinear articles, such as boot soles, from sheet material, and particularly to those for cutting unvulcanized sheeting on which designs are embossed, the said designs being located in the middle of the soles. Fig. 1 shows a front elevation and Fig. 2 a side elevation of a machine. The sheet U is fed over a roller c', which is rotated by a belt c<2> from a pulley driven from a main shaft a by the eccentric and ratchet-gear shown in Fig. 2. The material is passed between an upper roller c and a lower one, which is intermittently rotated by a wheel m<11>, actuated by ratchet-gear driven through a rod m<20> by a cam on the main shaft. After the material required for a sole has been fed forward, it is cut off by knives f, f<1>. The upper knife f is carried by a frame which is moved in guides in the frame of the lower knife by a cam on the main shaft. The blank thus cut off rests on a table s, and is clamped thereon by a pattern-plate p<1>, which is raised and lowered by a cam on a vertical shaft b acting through levers d. These levers are connected by a sliding spring sleeve. The table and clamping-plate are carried by co-axial spindles, journalled in a frame H, H<1>, which is swung about a vertical spindle by a cam on the shaft b. After the blank has been clamped on the table, the frame H, H<1> is swung round under the cutting-knife k<23>, which is then pulled down, to pierce the work, by a cam acting through a rod or line. The shaft b then rotates the vertical spindle and, through the gearing shown, the table and pattern-plate to cut out a sole. The wheels connecting the shaft band the vertical spindle have smooth portions arranged so that the latter is rotated during one half of each revolution of the former. The table and pattern plate are thus held stationary while the frame is being swung to and fro. After the sole has been cut out, a cam on the shaft b actuates levers l<2>, which hold the sole and scrap, while the table is swung back towards the knives f, f<1>, and then sweep them on to a travelling, band o, by which they are removed. The knife k<23> is swivelled in a boss k<17> in the manner shown in Fig. 21. It is provided with a guide roller bearing on the pattern plate, and is held normal to it by a pair of rollers k<29> also bearing on the pattern. India-rubber soles are preferably bevelled, and to enable this to be done the central portion of the pattern is grooved, as shown. The pattern may be made of wood with metal facing-plates. Fig. 24 shows tho gear for centering the embossed or other design on the sole blank. The material, as described above, is fed forward by a roller co-axial with the ratchet wheel m<11>, which is rotated by a pawl m<15>, reciprocated bv a cam on the main shaft. This pawl moves over an adjustable guard m<10>, so that only a variable portion of its stroke is effective in rotating the wheel. The position of the guard, and consequently the feed of the material, is determined by projections u<1> on the material, which strike an arm m6, connected to the guard by a lever m3 and a rod. The end of the arm is caused to move longitudinally by a wheel m<4> moving on a vertically-adjustable track m<5>. At intervals, the arm m<6> is raised, to allow a projection to pass, by means of a rod m<25> moved by a cam on the main spindle of the machine.
