Title: Improvements in or relating to apparatus for detecting and correcting departures from standard in the thickness or diameter of longitudinally travelling textile slivers
IPC: D01H5/40
Filed: 1947-05-15
Abstract: 656,135. Drafting textile fibres. RAPER, G. F. May 15, 1947, No. 13077. [Class 120(ii)] [Also in Group XIX] To correct departures from standard thickness or diameter in a longitudinally travelling sliver b, drafting members are regulated as to speed, pressure on the sliver or relative position by means of a controlling relay employing axially movable rods i carried by a moving wheel or chain and successively caused to project a distance corresponding to the diameter, the rod tips acting on the surface j<2> of a pivoted transmitting member j. In the diagram shown, the diameter is detected by a wheel d, pressed on the sliver in a grooved wheel a by an adjustable weight or spring (not shown), and rocking about the pivot e<1> of a magnifying lever e. Movement of the lever acts through a relay f to cause a yoke member g to move the rods i which are transversely slidable in a rotating wheel h. The rods subsequently act on the transmitter j to move it in a vertical plane perpendicular to the rod axes an amount depending on the extent of projection of the rods. This vertical movement acts through a relay k on a variable speed gear m to control the relative speed of pairs of drafting rollers n, n' and p, p<1>. The delayed action of the rods i is sufficient to allow the sliver to move the distance between the detection wheels a, d and the drafting rollers which correct the thickness. The rods i are returned to normal by plates r. Various modifications are described, e.g. the detecting mechanism may be incorporated in the drafting means. More than one transmitter may be provided, e.g. two may be positioned at different points around the same rod-carrying setter wheel so that their difference in movement, which may be detected by a pivoted lever, indicates continuously the average rate of change of diameter between two points on the sliver.

Abstract: 742,107. Securing wiper arms to shafts. PRODUCTIVE INVENTIONS, Inc. May 26, 1952 [July 3, 1951], No. 13309/52. Class 80(2) [Also in Group XXIII] Relates to means for securing the inner section of three-part wiper arm (see Group XXIII), to its actuating shaft. An inner arm or. cap section 1, Figs. 4, 5, engages a fluted drum 13 mounted on or integral with an actuating shaft 14. Mounted in the section 1 on a pivot 3, between the section 1 and an intermediate channel section arm 2, is a channel member 7 comprising a base 20 having side walls 21, and ears 22 extending from the side walls, which ears engage the pivot 3. The edge of the base 20 adjacent the drum 13 is formed with teeth 27 and the adjacent edges of the walls 21 are formed as long teeth 28. A screw 6, passing loosely through an aperture 18 in the section 1, engages the member 7. By manipulating the screw 6, the teeth 27, 28 are made to bite into the flutes 15 of the drum, so as tc draw the cap 1 thereonto and secure the cap to the shaft 14. Another screw 26 passes loosely through an aperture 25 in the base 20 and engages in a cranked lever 10 comprising a portion 31 provided with an aperture 34, a portion 32, and a portion 33 provided with an aperture 35. One end of an arm spring 9 engages in the aperture 34 whilst the screw 6 passes through the aperture 35. The lever 10 is pivoted to the screw 6 by engaging between a shoulder 37 thereon and the cap section 1. By manipulating the screw 26, the lever 10 can pivot into various positions, e.g. as shown in dotted lines in Fig. 4, so that the moment of the force of the spring about the pivot 3 is altered, and consequently the pressure of the wiper arm against the windscreen is varied. The tension in the spring, however, remains the same, since only its line of action is altered relative to the pivot 3. The spring also assists in uncoupling the member 7 from the drum when the screw 6 is loosened, by pulling on the lever 10 and the screw 26, and thus the member 7, the pivoting action of the member 7 on the pivot 3 then being permitted by the pivoting, of the screw 6 in the aperture 18.

Abstract: 1,178,494. Thermographic copying machines. EASTMAN KODAK CO. March 22, 1967 [March 25, 1966], No. 13429/67. Heading G2A. In a copying machine in which a matrix is thermographically exposed to an original and then a transfer copy is made by pressing the matrix into contact with a receiving paper, an electromechanical control system is provided which enables any predetermined number of transfer copies to be made automatically. The web matrix 9 winds across from a supply reel 8 to a take-up reel 16. The two reels are tendency driven in the same clockwise direction by a motor 18 and belt 20, and since the force required to drive them is greater than the tendency drive, belt 20 will merely slip and web 9 will remain stationary. The web also passes round guide rollers 10 and 12, and also a drive roller connected to a reversible motor 22. When the latter is energized, roller 14 is rotated in an anti-clockwise direction, and web 9 moves inthe direction of the arrows. An original document 30 is fed into the nip between web 9 and roller 12 where it is exposed to radiation from an infra-red lamp 28. The document is then separated from the web and directed into a receptacle 32, the web passing on to the copying station formed by a heated drum 34. This is normally out of contact with roller 14 because of a flattened peripheral part 56. In this position drum 34 is biased anti-clockwise by an off-centre weight 46, but is held against movement by a latch member 50 intercepting a latch element 48 on the drum. A container 60 holds a stack of receiving sheets 58. As the trailing edge of the exposed area of the matrix is about to leave roller 14, motor 22, and hence the movement of the matrix, is reversed. At the same time latch member 50 is retracted by a solenoid out of engagement with element 48, so that drum 34 can be rotated by weight 46 to bring it into peripheral contact with roller 14. Also, a motor-driven roller 62 is energized to feed the top sheet of stack 58 towards drum 34. Thus web 9 and sheet 58 are pressed together between roller 14 and drum 34, producing a transfer image on the sheet, which then passes on to a receptable 66. After one complete rotation, drum 34 loses contact with roller 14 again when the flat surface 56 is reached, but the drum continues to turn because of weight 46 until the Fig. 1 position is reached again, and element 48 is latched again by member 50. Motor 22 is once more reversed, so that the whole copying cycle is now repeated. A counting mechanism can be pre-set to the number of copies required. Fig.4 (not shown) is a diagram of a circuit for controlling the whole sequence of operations automatically. Fig. 5 (not shown) is a modification having a different arrangement for bringing the matrix and copy sheets into contact.
