Title: Method of and a device for producing typewritten copy with aligning margins
IPC: B41J29/42
Filed: 1957-05-23
Abstract: 807,604. Typewriters &c. GOY, A. May 23, 1957 [May 30, 1956], No. 16441/57. Class 100(4) In a typewriter having means for visually indicating the lengths of the typewritten lines so that justified copy may be subsequently produced by adding or subtracting the requisite number of letters spaces to the lines to be typed to bring them to a standard length, a numbered disc driven by the paper carriage rack indicates the number of times the paper carriage is stepped in each line of typescript. Disc 7, Figs. 1, 2 is adjustably mounted on shaft 4 for rotation therewith by locking nut 10. Shaft 4 is rotated by gear wheel 5 which meshes with rack 6 attached to the typewriter carriage. Before typing commences, and with the carriage at the right hand margin position, the desired line length is set by slackening nut 10 and rotating disc 7 until the appropriate number appears in window 12, Fig. 2. Each spacing unit stepped by the carriage turns disc 7 by one digit, thus, the number appearing in the window 12 at the end of a line indicates the length of the line in spacing units. The difference between the actual line length and the standard line length can be noted and an appropriate correction made in the fair copy by expanding or contracting the spaces between a pair or pairs of words. Two extra spacer bars are provided. which step the carriage one and two spaces respectively, in addition to the normal one which steps the carriage four spaces. The numbers could be arranged on a line or rod instead of a disc.

Abstract: 812,671. Flooring units. PIODI, R. May 24, 1957 [June 27, 1956], No. 16585/57. Class 87(1) A rubber &c. flooring unit has undercut tongues 2, Figs. 1, 6, on two adjacent sides and corresponding grooves 3 in the other two sides, each tongue having one end flush with the bottom of the adjacent groove and its other end spaced from the adjacent corner of the unit. The grooves may be closed at the ends remote from the tongues (Fig. 9, not shown). The tongues and grooves may be interrupted and spaced by gaps; in a rectangular unit, the groove in the longer side may be continuous to facilitate sliding engagement with an adjacent unit while the groove in the shorter side is interrupted and can be engaged with the spaced tongues on an adjacent unit by a "snap action". An alternative form of tongue, Fig. 8, has a crosssection consisting of an arrow-head 12A connected to the unit by a stem 12B, the head 12A being slightly smaller than the part 13A of the groove while the stem 12B is slightly longer than the part 13B. The surfaces 15 above and below the tongue are inclined so that the angle c is less than 90 degrees. Intersecting grooves 5 are formed in the lower face of the unit and the upper edge may be rabbeted at 7, Fig. 6. The unit comprises an upper layer 1 of hard rubber and a lower layer 4 of softer, preferably spongy, rubber or a rubber mix with a cotton filler.

Title: Supply mechanism for wire and other strands
IPC: B21C1/02
Filed: 1943-10-12
Abstract: 574,690. Winding wire or other strands. SYNCRO MACHINE CO. Oct. 12, 1943, No. 16699. Convention date, Dec. 8, 1942. [Class 120 (ii)] [Also in Group XXII] Means for supplying wire and other strands to a processing machine, for example a wiredrawing machine, embodying a storage device for wire sufficient to supply the machine till this comes to rest on the operation of stop mechanism due to stoppage of supply, for example, due to a kink in the wire. Wire W pulled through a drawing-machine by a drum 3 and reeled at 4 passes from a supply coil 6 through a guide tube 12, friction pad 13, guide eye 14, over a pulley 15 on an arm 16, to a drum 17 round which it passes a sufficient number of times to afford the required storage and is delivered by a pulley 18 on an arm 19 to the machine. The arms 16, 19 and the drum 17 are rotatably mounted on a tube 20 supported by a plate 10 from a standard 7. Should the wire jam as by a kink fouling the end of the tube 12 the arm 16 at once swings down to the dotted position, Fig. 4, against a biasing spring 40, a projection 35 riding against a collar 34 pinned on a spindle 23 within the tube 20. On arriving 'at the dotted position, the projection 35 aligns with a slot in the collar and a spring 36, adjustably tensioned at 22, forces the spindle 23 to the right, Fig. 3, removing a cross-pin 28, sliding in a slot in the end of the tube 20, from between lugs 29 on the boss of the arm 19 counterweighted at 19<1>. The arm 19 is now free to revolve and unwrap the wire from the drum 17. A lug 30 on the arm engages between lugs 31 on an adjustable bra,ke 32 that prevents the drum 17 from overrunning whilst in normal operation. Rotation of the drum, under the influence of the brake, in the reverse direction, is prevented by a spring-biased cam 41. As the rod 23 moves to the right an arm 25 operates a switch arm 26 to stop the motor 2 driving the wire-drawing machine. Before starting up again, the arm 19 is rotated to restore the requisite turns to the drum 17 and the spindle 23 is returned by a knob 24, allowing the spring 40 to return the arm 16 and a spring not shown to close the switch.
