Title: Improvements in typewriting machines
IPC: B41J17/00
Filed: 1920-09-07
Abstract: 163,949. Fairweather, W. C., (Underwood Typewriter Co.). Sept. 7, 1920. Web and sheet feeding and guiding arrangements.-In web-manifolding arrangements of the kind described in Specification 23349/14, the webs are eased to permit of retraction of the interleaved carbon sheets, by reducing the angle of the contact of the webs with the platen roller; a record-sheet may be employed for receiving a record of the items printed on the webs. In the arrangement shown, the webs 9 pass horizontally to the platen roller 2 and are received by an inclined table 22 normally occupying the position shown. The table is secured to brackets 23 which can rock on the platen axle 3, a stop pin limiting the movement by engaging one of the brackets or a tail 27 thereon. The table is held in the normal position by a spring-urged hook 33 which engages a pin 34; the hook can be released by means of a lever 35. The webs pass over a table 10 and are guided by a plate 42, the rear carriagerail 8 being placed at a low level to permit of horizontal arrangement of the webs. The webs are held in contact with the platen roller by an apron 20, and feed-rollers 11, 21 which are automatically released when the table is rocked forwards. For this purpose, one of the brackets 23 is connected by a link 39 to an arm 40 on the releasing-shafe 41. To permit release of the feedrollers by means of the usual lever, the link 39 has pin-and-slot connection 78 with the bracket. When the table is rocked forwards, the feedrollers are released and the angle of contact of the webs and the platen roller is reduced sufficiently to permit the webs to be drawn up to a stop 28, and the carbon sheets 12 to be retracted by pushing rearwards the handle 30 of the carbon-sheet trolly. A record-sheet 52, placed on the shelf 53, passes around the platen roller and is engaged by a feed-roller 54 carried by spring-urged arms 56, which can be raised by means of a release lever 57. Web-cutting arrangements. - The table 22 is provided with a tearing-edge 32 for severing the webs 9. Line-spacing mechanism.-When the webs are drawn up to the stops 28, the record-sheet remains stationary and it is therefore necessary to move the record-sheet by operating the line-spacing mechanism. Such operation may be effected by means of the line-spacing lever 46, but preferably the line-spacing mechanism is arranged for automatic operation when the table 22 is rocked forwards. For this purpose, one of the brackets 23 has pin-and-slot connection 61 with a lever 67 engaging the line-spacing slide 45.

Sept. 18, 1933, No. 25749. [Classes 83 (ii), 83 (iii), and 83 (iv).] Blanks, transferring.-A machine comprises means for positioning a can and a sheet metal member to be secured thereto, means to arrest the motion of a die-carrier when the die-sections suspended therefrom contact the can, and a wedging member, the continued movement of which expands the die sections and effects the securing operation. A spout 15, Fig. 6, with its base 17 perforated at 18 is secured within the closure 13 by a tool comprising sections 50 normally held substantially in the form of a cylinder by a spring 57, but expanded by a tapered reciprocating member 51 to cause teeth 59 to raise a series of locking projections on the spout and closure member. The sections are assembled, with ribs 52 engaging a groove in the holder, by passing them through a cut away portion which is afterwards closed by the can member 54. A cam A, Fig. 1, with its spout 15 is supported on a table 22 and located by a gauge 100, 106, beneath the tool 50. Pressure fluid is admitted to a cylinder 60 by a pedal actuated valve and operates the tool through a piston rod 63, bell crank lever 91, link 92, and toggle levers 94, 96. The sections move to contact the base of the spout, the movement of the member 41 being limited by a flange 41<a> and a lost motion connection 42, 43 permits further movement of the member 51 to spread the sections to secure the spout. The effective lengths of the members 63, 34, 36, and 38 are adjustable by the means shown. In a modification wherein a succession of cans is automatically operated on, cans 110, Fig. 13, are fed by a conveyer 173 to arms 179 of a conveying wheel 174, the arms being angularly adjustable relatively to the rest of the mechanism by screws 185. Before the cans pass to the rotating table 121 of the machine, the spouts strike a fixed cam to locate them accurately on the can. Each can is delivered to the table beneath one of a set of mechanisms 157 similar to that above described the reciprocation of the spindles being effected by fixed cams 161, 164 engaging rollers 159, 160 thereon. The rotation of the table and the supports for the securing mechanisms is effected by a motor 172, Fig. 13, through a gear 165 driving the large gear 122. A vertical adjustment to accommodate cans of different height is obtained by a crank 136 through bevel gearing 133, 135 and a screwed shaft 132. Discs 189, 190, Fig. 13, of different sizes may be used to accommodate different widths of cans. The cans are ejected from the machine by a wheel 174<a> and conveyer 192,
