Abstract: 973,187. Printing-machines. A. BRODY. June 14, 1962 [June 21, 1961], No. 22822/62. Headings B6B, B6C, B6D, B6E, B6F and B6H. Platen-machines; dating-presses.-Apparatus for printing borrower identification information from a library book borrower's card on to a book card relating to a borrowed book comprises a printing head 44, Figs. 7 and 23, having means comprising rails 85, Fig. 16 (viewed from underneath). The borrower's card 78, having an embossed printing area 79, is inserted manually above a plate 87 until the area 79 is exposed to the left of the plate 87, Fig. 16. An ink ribbon 82 passes below the head 44 and plate 87. To the head is secured a dating-mechanism 110 which prints a bookreturn-due date on the book card. The mechanism 110 comprises four date-stamp plates 109, Fig. 22, arranged at 90 degrees angular spacing around a spindle 108. Before printing, the selected stamp is brought into operative position by pushing in and rotating a knob 110. An electric motor is caused to make one revolution when a book card 70 is manually inserted on a platen 30 in a position determined by manually adjustable guides, and through a crank mechanism causes a shaft 36 to be oscillated and, by means of an eccentric 42, move the head 44 down against the platen and up again. A strip 51 having pressure-sensitive adhesive on its lower surface is fed from a roll below the head, and a knife 57 severs a portion 59 of the strip, on to which printing takes place. The strip is then adhesively attached to the book card. The strip is thus printed with the borrower information, and with the due date twice. A line of weakening is provided on the strip between the two dates, one of which is torn off and adhesively attached to the book, the other date projecting from the book card as a tab in a position determined by the adjustable guides. There is no adhesive on the strip at the projecting tab portion. The book card is then filed. Stopping. starting &c.-An electric relay circuit is provided, whereby the motor is started only when a microswitch 113 is closed by the moving in of the knob 110 and when a second microswitch is closed by the placing of the book card on the platen. The switch 113 is opened when the knob 110 is moved out on descent of the head 44 by a cam 101. An actuator on the motor shaft opens a third microswitch to stop the motor after one revolution, the motor being braked by a current passed therethrough by the discharging of a condenser. Applications of cutting-apparatus.-The cutter 57 secured to the printing head 44 is provided with a shearing edge 58 in the form of a shallow inverted V, which co-operates with a shearing edge 56 of a fixed plate 55. Feeding webs.-A web feed roller 53 is rotated intermittently from the oscillating shaft 36 through a uni-directional clutch 77 which allows forward feed only. Typewriters.-There is provided on the underside of the plate 87 a pivoted lever 97 settable manually in a selected position by means of a detent on the upper side of its lefthand end, Fig. 16, co-operating with recesses 100 in the plate. A downwardly extending portion 99 prints a code dot on the strip in a location on the book card determined by the position of the book card and of the lever 97. Filing papers.-The book card to be filed is thus provided with a removable adhesively attached strip projecting in the form of a date tab from one of its long edges in a preselected position.
