Title: Improvements in sheaths for wires, cables and the like, and in machines for producing the same
IPC: H01B13/26
Filed: 1931-10-24
Abstract: 375,176. Braiding-machines ; braid. MASCHINENFABRIK SCHWEITER AKT.-GES., Horgen, Switzerland. Oct. 24, 1931, No. 29580. Convention date, Nov. 4, 1930. [Class 74 (i).] A cable sheath for protective, insulating or ornamental purposes is composed of two covering layers a, a<1>, b, b<1>, Fig. 3, wound in opposite directions and braided to each other only at diametrically opposite places. The sheath which is of material such as silk is produced by a braiding machine which is driven from a shaft 1 fitted with bevel wheels 2, 4 and a spur gear 3. A cylindrical post 5<1> has a concentric groove for guiding a bevel wheel 6 driven by the wheel 4. The wheel 6 has diametrically opposed carriers 19, 19<1> for bobbins 20, 20<1>, and thread guides 21, 22 with eyes 23, 24, 25. The bearing groove for the wheel 6 is slightly inclined to the braiding axis. A support 7 fixed to a bedplate 5 is formed at the top as a segment provided with a guide groove 71 and forms with a grooved cap 5<2> a circular track which is interrupted at two gaps 38, 39. The grooves guide diametrically opposed toothed segments 26, 27 which are driven by bevel gearing. Each segment carries a bobbin holder 28, 28<1> with a bobbin 29, 291 and a thread guide 30, 31 with eyes 32, 33. The braiding spindle is a vertical tube 34 with a flat cap 35. The gaps 38, 39 permit passage of the thread guides 21, 22. In operation, the bobbins 29, 29<1> on the upper track 5<2>, 71 and the bobbins 20, 20<1> en the lower track rotate in opposite directions, and as the wire 36 to be covered is moved forward, the braid bands a, a<1> of the upper track ire laid with a right-hand turn on the wire, the bands b, b<1> from the lower track being laid with a left-hand turn.

Title: Elastic guiding device
IPC: F16C11/06
Filed: 1937-10-29
Abstract: 497,624. Universal joints. THIRY, L. Oct. 29, 1937, No. 29585. Convention date, Nov. 7, 1936. [Class 80 (ii)] [Also in Group XXV] An elastic connection between two members, such as the shafts 1, 2 in a cardan joint, of which the longitudinal axes meet one another and each is adapted to take up any angular position relative to the other within a limiting cone, comprises at least one ring 7 of elastic material of rounded cross-section inserted between co-operating surfaces of the members on each side of the plane XX bisecting the angle between the axes of the members, the rings on opposite sides of the plane having different natures, dimensions or arrangements so as to afford different degrees of elasticity according to whether the members are moved towards or away from one another. The rings 7 are radially deformed, for example by circumferential elongation, so that they will adhere to the surfaces of the members and will roll without sliding on these surfaces when the members are displaced. In the form shown, the shaft 1 has a head 3 which is symmetrical about a plane at right-angles to its axis and the shaft 2 has a corresponding socket 4, so that the rubber rings 7 have the same size and arrangement, but one of the rings is made harder than the other, for example by a difference in composition, so that the resistance to motion in a direction which produces compression in one ring is greater than to motion in the opposite direction. This difference of resistance may be obtained by making the head 3 or the socket 4 of different size or shape on one side of the plane XX from the other, by placing the rings at different distances from the plane XX, or by making the rings of different initial dimensions ; any of these devices may be used in combination. The corresponding surfaces of the head 3 and socket 4 need not be parallel as in the form shown, and may be curved longitudinally, for example spherical or ellipsoidal. Stops may be provided for limiting the relative displacements of the members. The Specification as open to inspection under Sect. 91 also states that " adjusting means may be provided adapted to vary the initial deformations of the various elastic masses, for example by bringing one or more of the surfaces which determine at least one of the annular spaces to a greater or less distance from the other." This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the prevention of permanent deformation of steel or alloy steel during surface hardening
IPC: C21D1/06
Filed: 1946-10-04
Abstract: 620,516. Heat-treating. STIVIN, J. Oct. 4, 1946. No. 29680. Convention date, Jan. 5, 1944. [Class 72] In a method of eliminating permanent deformation in the surface hardening of steel and alloy steel, the temporary deformation of the article during surface heating is restricted so that the suppressed part of the deformation causes a compression of the heated surface resulting in a permanent deformation which compensates the deformation due to the increase in the specific volume of the surface layer on quenching. As shown, a flat strip or ruler 1 to be hardened on its lower surface rests on a heating device 3 fed with high frequency current. Adjustable stops 4 disposed in arms 5 of a stirrup-like device 6 suppress the bending upwards of the ends to such an extent that, on quenching, the ruler remains flat. In a modification Figs. 6, 7, applied to the suface hardening of rails, rollers 41, 42. and 43 suppress part of the deformation due to heating the surface 38 by the heater 39. The invention is also described applied to piston rings, Fig. 3 (not shown) bevel gears, Fig. 5 (not shown) and connecting rod heads, Fig. 4 (not shown).

April 16, 1935, No. 29720. Divided out of 442,934. [Class 124] [See also Group XXIV] Relates to a percussive tool of the kind in which the hammer comprises a reciprocating frame 5, on which are mounted out-of-balance wheels 7 rotated in opposite directions by a bevel pinion 8 on the motor shaft 2, the centres of gravity of the wheels being coplanar with the axis of rotation twice in a revolution, the couple generated due to the fact that the wheels 7 are spaced apart being utilized for imparting rotary motion to the tool by means of a ratchet 14, 15. The ratchet is frictionally held in the casing so as to slip above a certain torque. As shown, the oscillator 5 is splined at 5b to the tool holder 13, which carries pawls 14 engaging a ratchet ring 15 pressed by a spring 16 against a shoulder 4a of the casing to produce the frictional grip. The spring 16 abuts against the ratchet through a ring 24, and the whole ratchet device slides axially as the tool reciprocates. The angular impulses of the oscillator 5 rotate the tool freely in one direction, but in the other are absorbed by the ratchet.
