Title: Improvements in or relating to knitting machines
IPC: D04B15/74
Filed: 1935-04-25
Abstract: 455,502. Knitting. STIBBE & CO., Ltd., G., 9, Newarke Street, Leicester.-(Wildman Manufacturing Co. ; Norristown, Pennsylvania, U.S.A.) April 25, 1935, No. 12451. [Class 74 (ii)] In a spring - beard needle knitting - machine having individually movable pressers, selector cams are individually movable to and from operative position by means of horizontal slide bars movable substantially at right-angles to the direction of movement of the cams so that any one or more of the cams can act upon a needle or needles (or associated jacks) having differently positioned butts, there being one cam for each butt position. Jacks 29 bear differently positioned intermediate butts 29a which are acted upon by a bank of individually movable selector cams 31, selected of the jacks being thus pushed back into their tricks 33a so that their butts 29b miss a jack raising cam 35 which either raises the other needles to clearing height, or lands their butts 29c on a clearing cam. The jacks are subsequently lowered by another cam and those which were acted on by cams 31 are now moved forward in their tricks by an incline 39c. The cam 35 consists of two horizontal ledges 35b, 35c, along the first of which all the butts 29b travel with the upper ends of the jacks adjacent the needle butts. Only the butts of those jacks which are not pressed in by the cams 31, ride up the incline 35e on to the higher ledge 35c. The jacks are held forward in their tricks by coacting inclines on the butts 29b and on the inclines on the cam 35, or by humps on the jacks engaging suitably shaped recesses in jack cylinder 33. A jack guard cam keeps the butts 29b in contact with the cam 35, whilst a further cam at each selecting point holds back the needles, as they are raised and also presents their falling below the normal non-knitting position. The selector cams 31 are pivoted one above another on a spindle 53 and each can be rocked to operative position by an associated slide bar 52 movable in a direction at right angles to the direction of movement of the cams, and pattern controlled, or moved manually or by a suitable instrument, by means of a head on the slide bar. These heads may be of varying length to facilitate prearrangement. Springs 54 and 57 serve to hold each cam and slide bar in the inoperative and operative positions respectively, and adjustable stops may be provided. The cams may be slidably, or otherwise movably mounted. A further cam may be provided at each feeder for nullifying the action of the needle controlling cam means, such cam being operated at prearranged intervals, as by means of a timing or pattern chain. The combination may include cam means for operating the individually movable pressers non-selectively or selectively, as described in Specification 441,853.

Title: System for optically reading and transmitting data
IPC: H03M1/00
Filed: 1965-03-30
Abstract: 1,042,692. Modulating light. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 30, 1965 [June 30, 1964], No. 13340/65. Heading H4F. [Also in Division G4] A system comprises deflection means for deflecting an input beam of plane polarized light from an input path to any selected location on an information storage element whereby the beam is conditioned in accordance with the stored information, means for returning the conditioned light beam through the deflection means to the input path polarized in a plane at 90 degrees to the plane of polarization of the input light beam, and means for separating the input beam from the conditioned beam, wherein the deflection means comprises a series of birefringent crystals with binary-weighted thicknesses arranged along the path of the light beam and each preceded by an electro-optic element adapted when energized to rotate the plane of polarization by 90 degrees. The deflection means laterally displaces the input light beam by an amount depending on what combination of electro-optic elements are energized. The means for separating the conditioned beam from the input beam is a beam splitter. In Fig. 2 (not shown) the unconditioned light emerging from the deflection means is returned to it by a roof-top reflector via a half-wave plate. In Fig. 3 (not shown), the returning means involves a second beam splitter, three quarterwave plates, a roof-top reflector, a plane reflector and an information storage plate. This plate is transparent with reflecting layers spaced periodically through its thickness and reflects selected frequencies in the incident light to indicate the information stored. The plate is described in Specification 1,037,888 which is referred to. The reflected light, after passage through the deflection means &c., is passed through a prism to separate out the various frequencies on to a line of photo-cells. The embodiment also uses an extra electro-optic element and a half-wave plate. Fig. 4 (not shown) shows a slight modification of Fig. 3 (not shown), and Fig. 5 (not shown) shows a further modification in which the information storage element is a character mask to impress on the light beam the shape of a selected character. The beam is finally directed by a rotatable reflector on to a selected part of a photo-sensitive medium to print the character.

Title: Spindle belt or tape drive
IPC: D01H1/241
Filed: 1961-04-14
Abstract: 913,065. Belt and toothed gearing. KEYSER, J. J. April 14, 1961 [April 16, 1960], No. 13431/61. Class 80 (1). [Also in Group IX] A spindle drive comprises a drum near the spindle, the spindle lying in a plane at rightangles to the drum axis, an endless belt around the drum and the spindle-wharve without tensioning or guide pulleys, the axial length of the wharve surface contacted by the belt extending at least between two planes at right-angles to the spindle, one passing through the drum axis and the other being tangential to the drum. The drive is transmitted through a clutch either between the wharve and the carrier or between the drum and the driving shaft, the belt moving between a central position on the wharve when the drive is interrupted, to one at one of the ends of the wharve (depending on the direction of the drive) when the drive is in progress. The drum 2, belt 5 and wharve 13 are enclosed in a hollow spindle rod 1 having a detachable cover 7. In Fig. 1, where the clutch is at 17 between the wharve and the bobbin carrier 16, the wharve is rotatably mounted in bearings 14, 15. The clutch may comprise a collar 18 connected to the bobbin carrier 16 and pressed against a cage 22 of a bearing 23 by springs 20 so that the bearing rotates as a unit with the wharve 13 and a casing 17 connected to the sleeve carrier. To interrupt the drive, a handle 9 is rotated to cause a nut 27 torise ona fixed threaded bushing 28 and lift the collar off the cage through a resilient disc 27, the casing 17 and sleeve 16, the carrier being braked by engagement of disc 26 with nut 27. In Fig. 2, where the clutch is in the drum 2<SP>1</SP>, the spindle is mounted in a tubular member 35 inside the wharve by bearings 37, 38, the former being adjustable for spindles of different lengths, and the carrier 13<SP>1</SP> which is a tight fit at 40 in the spindle drives the sleeve 6 by a tubular member 33 having an elastic ring 34. The clutch is operated by a handle 9 which is connected to a yoke 28 carrying members 29 engaging a groove 30 in a part 31 keyed to the shaft 3 and slidable into and out of engagement with the drum. The disengagement of the clutch may be co-ordinated with a braking operation on the spindle. Each bobbin in a row may be driven from its own drum and mounted on a common shaft or from a common drum: when two opposite rows of spindles are driven from a centrally-arranged drum the spindles may be staggered on either side the wharves, the distance between the axis of each spindle and that of its opposite number on the other side of the drum being at least equal to one-half the diameter of the wharve; the belts and drum are arranged in a common housing, and the belts of one set of spindles are arranged on the upper parts of the wharves and those of the other set on the lower parts (Figs. 5 and 6, not shown). The construction provides a smooth start and allows the belts to adjust themselves despite slight differences in length in a multi-spindle arrangement.
