Abstract: 828,476. Sewing machines. MEFINA S. A. May 30, 1957 [Aug. 9, 1956; March 8, 1957], No. 17148/57. Class 112 Button-hole sewing machines; needles, shifting laterally. An accessory for facilitating stitching on a zig-zag sewing machine, comprises an auxiliary cam for actuating the feed control mechanism and a connecting member which is adapted for coupling to the member for adjusting the amplitude of needle swing, so that movement of this adjusting member also alters the angular position of the auxiliary cam. The accessory is applied to the sewing machine described in Specification 683,291. It comprises concentric sleeves 41, 49 mounted on a shaft 13 which drives the inner sleeve 41. The sleeve 41 carries a pattern cam 1a for effecting needle swing, and the sleeve 49 constituting the auxiliary cam is formed with a flange 54 having cam notches 56, 57 which co-operate with a pivoted feeler 33 of the feed-control mechanism, and with a pin 59 co-operating with a finger 106 on a pivoted lever 99 of mechanism determining the needle position. The connecting member 45 consists of a ring 48 freely mounted on the sleeve 41 and provided with an arm engaging a notch 56 in the flange 54 and having a forked end 47 embracing the part 16 of the member 15 by which the amplitude of needle swing is adjusted. The notch 56 makes a predetermined angular clearance with the arm of the connecting member. To effect button-hole stitching the member 15 is moved to position 0 and the wheel 22 is turned to centre the needle to the left. Member 15 is then moved to position 2 to effect engagement of cam notch 56 with the follower 33 and the machine is started to effect stitching 109 of small amplitude with forward feed. Member 15 is then moved to position 4 to effect engagement of cam notch 57 for reverse feed and to effect movement of lever 99 by pin 59 to move the needle to the right. Stitching of large amplitude is then effected. Member 15 is then moved back to position 2, without moving the auxiliary cam, to effect stitching of small amplitude. Finally, member 15 is moved back to position 4 to complete the buttonhole. In a modified accessory the pin 59 is omitted, the shift of the needle being effected by the wheel 22. Further, the pattern cam 1a, may be separate from the accessory. In a further modification there are three sets of notches 56, 57 giving three rates of feed for fabrics of differing thickness, and three corresponding pins 59 are provided to effect movement of the needle to the right. The sleeve 49 and the connecting member 45 may be moved relatively to occupy three different positions, in each of which they may be secured together by means of a pivoted spring- loaded finger mounted on the arm of the connecting member and adapted to engage a corresponding notch provided in the flange 54 of the sleeve 49.

Abstract: 329,192. Pashley, W. R. June 7, 1929. Supports attached to cycles.-In a stand for motor and other cycles, and particularly carrier cycles, of the type in which a supporting arm is adapted to be moved from a plane parallel with the machine into a transverse plane, the stand is adapted to be turned into its operative transverse position by a simple rotary movement against the action of a spring, the stand arm moving in substantially the same horizontal plane from its inoperative to its operative position and being adapted to be locked in the latter position until released by hand or foot, the spring then serving to return the stand to its inoperative position. The stand comprises an arm 1 having downwardly-bent ends 2, either of which is adapted to engage the ground according to the side to which the cycle is made to lean, the arm 1, which normally lies in the plane of the frame, being turned into its transverse operative position by rotating a rod or tube 4, which is mounted in bearings 5, 8, 13, the bearings 8, 13 being formed on a bracket 9. The rod 4 is acted upon by a torsion spring 20, and by a compression spring 22 tending to push the rod upwardly. In the inoperative position, the arm 1 is held against upward movement by engagement with a transverse projection 15 on the bracket 9, and is prevented from turning by engagement with a projection 17 on the bracket 9. In order to bring the arm 1 into the transverse operative position, the rod 4 is rotated by a handle 12 &c., and the arm 1 moves clear of the projection 15 and moves upwardly under the action of the spring 22 into a recess 18 in the bracket 9, and is thus retained in the transverse position. The clearance distance of the arm 1 from the rear wheel in the inoperative position may be adjusted by means of a set screw or stud carried by the projection 17. The rod 4 may alternatively be rotated by means of a sliding member through screw and nut mechanism of quick pitch.

Abstract: 458,421. Photo-mechanical printing- surfaces. REDDIE, L. N., 6, Bream's Buildings, Fetter Lane, London.-(Naamlooze Vennootschap Nederlandsche Laboratorium de Spaarnestad; 51, Nassaulaan, Haarlem, Holland) June 18, 1935, No. 17572. [Class 98 (ii)] In producing screened images, a halftone original is copied through a screen onto a light-sensitive layer which is highly light diffusing so that the sizes of the images of the elements of the screen pattern formed in the layer are determined by the brightness of corresponding parts of the original owing to the diffusion. The sensitive layer may be of bichromated gelatin in which pigment is incorporated or of silver halide with or without pigment. Suitable pigments are titanium dioxide or barium sulphate. The screens used are adapted to the nature of the printing forme to be produced, e.g. for intaglio formes a screen of transparent lines and opaque squares is used. The screens may be used in contact with the sensitive layer or the original or both. Alternatively the screen may be spaced from the sensitive layer by interposing a transparent film. A screen having slightly translucent elements in place of the opaque elements may also be used. Such a screen is prepared by copying a negative intaglio screen on a gelatined plate sensitized with ammonium ferri citrate and potassium ferricyanide. The diffusion effect may also be enhanced by copying with diffused or oblique light or by the use of a screen having refracting elements.
