Abstract: 7338. Entwisle, J., [Kursheedt Manufacturing Co.]. March 26. Cards, punching. -For punching- jacquard cards, the pattern is mounted on a board a<2>, which can be fixed in any desired position, and in front of this board are two vertically - movable frames B, B', each having a diagonal bar b<5>, b<6>. The bars cross at rightangles and carry a heavy block provided with a sight, which is moved to any part of the pattern by the act of moving the frames. This movement is effected by cords c<3> which operate separate wheels c<1>. The movement of one of the wheels c'is transmitted to a pin-wheel e', the shaft d<3> of which operates a countershaft d<18>, which drives another pinwheel e<2>. A Geneva stop device is interposed between these shafts, the shaft d<18> making one quarter revolution to one of the shaft d<3>. The other wheel c<1> in like manner operates pin-wheels e<4>, e<3>. The wheels c' can be disconnected from the pin-wheel operating - mechanism to enable the pattern to be set in any required position, while the pin - wheels are automatically disconnected and set to zero after each complete operation of the punches. When the pinwheels have been set by the act of moving the frames B, B<1>, a clutch is operated so as to bring into action those punches which the pin-wheels select. The punches are shown at I<0>, Fig. 9, and are arranged in two rows in a frame I<1> operated from a cam by an arm j<7>. This frame is moved twice at each setting of the punches, the paper being moved between each operation through a distance equal to that between the rows, so that all the punches make holes in a line. The object of this is to save space. The selecting-device consists of a number of pins i mounted in a movable frame I and supporting sliding bolts. The frame I drops periodically, and those pins i which are supported by pins on the pin-wheels remain raised and support their corresponding bolts in reach of plates i<11>, i<12> on cam-actuated shafts i<13>, i<14>. These shafts, when turned, thus move forward the bolts selected, so as to engage with corresponding punches when the punch frame is operated, and cause the paper K<2> to be perforated. The clutch is then automatically disconnected. Punches are also provided for making holes for moving the paper when in the jacquard. The machine also includes an embroidering-device C<0> which reproduces on a smaller scale the pattern on the board a<2> and enables the operator to check the work. The movements of the frames B, B<1> are communicated to the fabric, and the remaining motions are produced by gearing from the main shaft. Various special movements, such as operation of bore points, change of tension, and so on, are produced in the control apparatus by handles e<29>, each of which selects a special punch for correspondingly porforating the jacquard card. The device for doing this is shown in Fig. 40. An arm e<13> is reciprocated by a cam, and carries rods e<12> and e<30>. The former act on heart-shaped blocks e, while the latter restore to their normal positions those levers e' which have been disturbed by the movement of the blocks e<11>. The position of any rod e<12> is determined by the corresponding handle e<29> with which it is connected by a rod e<22>. The levers e<7> have pins e<5> which are carried in a fixed bearing d<0>, and are pushed forward in the way of the punch-selecting pins i and withdrawn from them, as will be obvious from Fig. 40. The needle and the bore point or points of the embroidery machine being on different levels, means are provided for shifting the work accordingly without disturbing the general operation of the apparatus. Locking-devices are provided so that no operation can be performed before its proper time.
