Abstract: 542,651. Typewriters. COPELAND, R. J. July 19, 1940, No. 11927. [Class 100 (iv)] A typewriter-attachment for simultaneously producing one or more originals and a mirror-script copy comprises a carrier which is attached to the carriage and also supported independently thereof, and is provided with holding-means for continuous original and copy sheets, and means for holding and feeding a continuous, or alternatively, a short hectograph sheet. In the apparatus shown in Fig. 1, a carrier or plate 2 having horizontal and depending parts is attached to the platen-carriage 4 and runs on rollers 7 on the framework. The plate is provided with brackets 9, 10 detachably supporting supply and winding spindles 11, 12 for a hectograph web 27 which passes around the platen 28. The spindles are connected by a belt 20 passing around pulleys, and each spindle is formed with a groove receiving a V-strip for attaching the web to the spindle. Original and duplicate webs 33, 35, are led from packs 32, 34 in holders 30, 31, pass under a guide 36 on the plate 2 and around the platen. The duplicate web 35 is disposed between the original web 33 and the hectograph web 27 and receives a mirror impression on the rear side. The hectograph web is fed from the spindle 11 to the spindle 12 at each line-spacing movement of the platen. The duplicate web prevents smudging of the original web, or typing on the rear side thereof. When one section of the webs has been typed, the webs are advanced ,and the original and duplicate sections are detached on the lines 37 and then separated, one of the sections having a notch 67 for facilitating separation. When the hectograph web has been wound on the spindle 12, the spindle 11 is turned by means of a crank 19 to re-wind the web. In a modification, Fig. 8, the brackets 10<SP>1</SP> supporting the heactograph-web spindles 11t, 12t are arranged on the horizontal part of the plate 2<SP>1</SP>, and this part is provided with pairs of rollers 46 for engaging trough-rails 44, 45 secured to standards 40 mounted adjustably in sockets 41 on the base of the typewriter. The plate supports a holder 55 for the stationery packs. For coupling the plate to the carriage 4<SP>1</SP>, the plate is provided at each side with a rod 51 having an inturned finger 53 freely engaging the carriage, the arrangement enabling the carriage to be shifted without disturbing the plate. The rods 51 are adjustably mounted in blocks 49 which are adjustably mounted on a spindle 47 rotatable in lugs 48 on the plate. The plate is provided with lugs 57, 58 and a curved part 3<SP>11</SP> for guiding the webs. A hectograph sheet may be used instead of a web. For this purpose, the apparatus shown in Fig. 8 may be modified by dispensing with the spindles 11<SP>1</SP>, 12<SP>1</SP>, and providing at the rear of the plate 2<SP>1</SP> a spring drum 61, Fig. 12, in connection with a tape 62 having a clip 63 for gripping a hectograph sheet 59. To prevent soiling of the fingers, the hectograph sheet may have a plain extension 60 for engaging the clip. After a section of the webs has been typed, the hectograph sheet is retracted by the spring drum, the movement being limited by co-operation of a finger 63<SP>1</SP> on the clip with an adjustable stop 65 mounted on a slotted strip 64 hinged to and overlying the plate. Specification 450,294 is referred to.
