Title: Improvements in or relating to steering gear for vehicles
IPC: B62D3/10
Filed: 1931-11-02
Abstract: 384,757. Motor-vehicle steering-gear. GEMMER MANUFACTURING CO., 6400, Mt. Elliott Street, Detroit, Michigan, U.S.A. -(Assignees of Marles, H. ; 52, East Palmer Avenue, Detroit, Michigan, U.S.A.) Nov. 2, 1931, No. 30361. Convention date, Jan. 12. [Class 79 (v).] A steering-gear worm A, of the hour-glass type, is engaged by a segment D having a central tooth F<1> and one or more teeth F, F2 on each side thereof, all such as might be simultaneously formed by the transverse rectilinear movement of a forming tool, the central tooth being in full engagement with the worm when in the central position of the gear, and the other teeth being concentric to an axis H different from the axis G of the central tooth and being of a lesser mean radius than that of the central tooth. The generating curve of the worm profile has its axis at I, so that the radius of this curve is greater than that of the gear segment. Thus, when the gear is in the central position shown the central tooth F<1> is in full mesh with the worm but the outer teeth are not in engagement. As the segment rotates from this position one of the outer teeth comes into engagement, but the central tooth is withdrawn from close contact due to the different centres G, I, and thus compensation is effected for inaccuracy in form due to the fact that the segment teeth are not developed.

Title: Improved process for treating cotton fabrics
IPC: D06M23/18
Filed: 1924-12-23
Abstract: Mercerized or non-mercerized cotton fabrics whether plain or provided with patterns or embroideries are given a transparent, translucent, or wool-like effect, and cotton fabrics made of coarser yarns are given a linen-like lustrous appearance by moistening the fabric with water until it has a moisture content of at least 30 per cent and then treating it with sulphuric acid or with sulphuric acid and an alkali lye.  Crape effects, which may be enhanced by dyeing, are produced by printing stripes or patterns in water on the dry fabric before the application of sulphuric acid at 50.6 DEG  B<\>ae. and a temperature of - 10 DEG  C.  The printed parts have a greater affinity for dyestuffs.  Examples are given of processes for producing wool-like effects in which the sulphuric is of a strength of 50.3 DEG  B<\>ae. at 5 DEG  C. and 50 DEG  B<\>ae. at 0 DEG  C., the duration of the treatment being one minute, and in which the fabric is given a softness and a transparent effect by treatment with sulphuric acid of 50 DEG  to 50.3 DEG  B<\>ae. at 0 DEG  C. for 1 to 2 minutes and subsequent mercerization under tension with cold lye. Hydrochloric, nitric, phosphoric, or a mixture of sulphuric and nitric acids may be used in place of sulphuric acid, and reserves may be used for the production of pattern effects.

Abstract: 797,341. Knitting-machines. COTTON, Ltd., W. Dec. 2, 1954 [Nov. 10, 1953; Feb. 5, 1954], Nos. 31122/53 and 3408/54. Class 74(2). A straight-bar machine for producing garments having V-necks has four sets of fashioning points and corresponding lead-screw mechanism for fashioning the inner and outer selvedges during the production of the V-neck. During production of the body portion of a garment two of the sets of fashioning points 61, 66 are out of action and use is made of their leadscrew mechanisms to operate marking or lacing points 60, 62, 69, Fig. 1, or 601, 62<SP>1</SP>, Fig. 2. For this purpose each lead-screw nut 37, 38 for the fashioning points 66, 61 is connected to a slipper 41, 42, slidable on rods 43. Each of the slippers 41, 42 carries a bolt 48, Fig. 6, which is manually adjusted to engage a roller 47, 49 on the corresponding fashioning point bar 44, 45, to enable the lead screws to operate the points 66, 61 for fashioning during the formation of the V-neck. During production of the body portion of a garment the bolts 48 are withdrawn and depending on whether it is desired to effect patterning by lace effect or marking, each slipper 41, 42 is connected to a rod 64, 58, 73 to enable the lead-screw mechanisms to operate the appropriate points carried by these rods. The rods are mounted on the narrowing head of the machine and are rotated to bring their points into an operative position whereby the points co-operate with the needles to transfer loops. Rotation of the rods also engages or disengages them with or from the slippers 41, 42 as the points are lowered into or raised out of operation. To this end each rod, for example rod 58, Fig. 6, carries two partcircular discs 57 which engage on either side of a plate 156 on the slipper 42 when the point 60 is lowered and disengages from the plate when the point is raised. The operation of the narrowing head and lead screws and the point rods may be controlled by the pattern chain of the machine. In association with the fashioning points and if desired, in association with the marking or lacing points, filling-up points may be provided comprising two halfpoints manually lowered and raised into and out of operative position to effect spreading of the inner loops during loop transfer. The filling-up points associated with two sets of other points may be operated simultaneously from the same manual lever.
