Title: Ball and socket joint rapidly dismountable
IPC: B60D1/06
Filed: 1947-07-18
Abstract: 633,162. Ball joints. BOUHOT, M. A. P. July 18, 1947, No. 19217. Convention date, April 4, 1940. [Class 65 (ii)] In a readily separable ball and socket joint of the kind in which the ball end of a member 2 is pressed against the closed end of a tubular socket 1 by a slidable push-piece 3 adapted to be moved by means of an operating member accessible from outside the socket, the-operating member is in the form of a plate 4 movably disposed in longitudinal slots 5 and 6 in the socket. The mutually adjacent edges of the push piece and plate are so shaped that the push piece is caused to move towards the closed end of the socket under the action of a spring 8 bearing upon the plate, while it is free to move away from the closed end when the plate is acted upon against the action of the spring. A pin 11 which passes through an aperture 12 in the push piece limits the movement of the latter. The mutually adjacent edges are straight or curved. In a modification the plate is in the form of a rotatable cam and the spring is anchored at one of its ends to the pin 11.

Title: Improvements relating to spooling in machines for spinning artificial threads
IPC: B65H54/74
Filed: 1938-06-29
Abstract: 516,583. Winding artificial silk; electric motor control systems. I. G. FARBENINDUSTRIE AKT.-GES. June 29, 1938, No. 19307. Convention date, June 29, 1937. [Class 120 (ii)] [Also in Group XXXVII] In a machine for winding up artificial silk as it is spun on to one or other of two sets of bobbins each driven by its own motor'having a controlled variable speed so that the draft on the thread is constant, the stationary and running motors are respectively cut in and cut out simultaneously with the coupling or uncoupling of the drive which controls the speeds of the motors. As shown the motor M<111>, controlling the speed of the motors M<1>, M<11> driving the bobbin sets S', S<2> respectively, is geared to pinions F loose on shaft f<1>, f<2> and carrying clutch members adapted to be engaged by clutch members v<1>, v<2> splined on the shafts and connected to rods h', h<2> which respectively control the switches u<1>, u<2> of the motors M', M<11>. The pinions F are also geared by chains K<1>, K<2> to wheels R<1>, R" on the shafts a which are slowly rotated to shift the brushes of the motors M', M" and continually vary their speed, each shaft carrying a disc b turning behind a stationary pointer z to indicate the speed of the shaft; the discs are urged by weighted cords C against the drive of the wheels R', R" and when the clutch v<1> or v<2> is disengaged the corresponding control shaft a is rotated by the weighted cord back to its initial position, determined by the contact of an adjustable stop on the disc b with a stationary abutment. As a bobbin motor is stopped by actuating the corresponding control rod h' or h<2>, the drive from the motor M<111> is also interrupted and at the same time, when the bobbins are being wound with a varying traverse, a connection from the rod moves a roller in a cam track m to actuate a pivoted lever n which controls clutches y', y<2> on a shaft x geared to the device V for varying the stroke of the thread laying guide; the disengagement of the clutch y<1> and the engagement of the clutch y<2> drives the shaft x, which then returns the thread laying device to its initial position while the clutch y<1> is brought into engagement with a device, actuated at the end of the stroke of the lever n, to restart the thread-laying device; when the rod h' or h<2> is moved to cut in its motor the lever n is not moved.

Abstract: 592,085. Hand looms; beaming; carpet making. FLORJANCIC, P., and BORAL, E. Oct, 9, 1944, No. 19372. [Classes 142 (ii) and 142 (iv)] The hand loom described in Specification 586,221 is so constructed that, in conjunction with additional parts, it can be re-assembled as a beaming apparatus or a carpet knotting frame. For beaming (Figs. 3, 4), battens 58, to carry bobbins, are mounted on a rear cross bar of the loom and the shuttle race 27 and reed 29 are removed from the slay 28 and mounted, together with a member 62, on the front corner posts 49, the shedding mechanism being preferably also removed. The yarns pass through the reed, round the member 62, and through the reed again, and are wound on the beam 32 in conical sections produced by a threaded spindle 66 traversing the beam as it is rotated. Alternatively, the battens 58, the reed 29, and the member 62 may be mounted on a carriage supported by the shuttle race and a cross bar of the loom so as to be transversely displaceable after winding each section. In a modification, Fig. 11, a reed 84, a brake 83, lease rods 81, and an expansion reed 80, which may be carried by a common support, are mounted on the loom. The expansion reed, Fig. 10, has dents 99 carried by compression springs 98 disposed between nuts 95 on shafts having right and left hand threads. The shafts are coupled together by a chain drive 103 and the spacing of the dents can be adjusted by a hand wheel 100 provided with a resilient pawl 101, the setting being indicated by a pointer 104. A frame for carpet knotting, Fig. 8, is formed by pairs 48, 49 of the loom corner posts, loom cross bars 1, 47, and additional members 72, 74 and rollers 75, 76. The cross bars 26 of the loom frame, Fig. 7, are tabular and have studs 52 secured in their ends by split pins 53 for ease in dismantling.

Abstract: 258,395. Western Electric Co.. Ltd., (Bell Telephone Laboratories, Inc.). July 31, 1925. Addition to 221,792. Harmonic telegraphs; transmitters for hand signalling.-Comprises a mechanical wave filter associated with a keying device. In the arrangement shown, mechanical wave filters of the kind described in the parent Specification are associated with (1) a source of mechanical vibration such as notched discs VI, V2 mounted on a rotating shaft 1 and adapted to strike the anvils 3, 4; (2) an electrical output device such as a rotary shaft 5 carrying the armature 10 of an electromagnetic transmitter. 6, the amplified oscillations from which are communicated to the signalling line L ; and (3) signalling means such as keys 17, 18, controlling the brakes 11, 12, so that unless a key is depressed the corresponding filter F1, F2, is blocked, no vibrations being able to pass through it from the shaft 1 to the shaft 5. Each filter, F1, F2, passes a different band of frequencies, and the sum of the oscillations reaching the shaft 5, as the signalling keys are independently operated, appears in the line L as a multiplex group of signalling currents. The arrangements shown are equivalent to electric wave filters terminated mid-shunt and having their input and output circuits connected in series, but a mid-series arrangement with shuntconnected terminals may be substituted if desired.

Title: Improvements in or relating to cloth cutting devices for sewing machines
IPC: D05B37/04
Filed: 1957-06-21
Abstract: 862,746. Sewing-machines. PFAFF A. G., G. M. June 21, 1957 [June 26, 1956], No. 19539/57. Class 112 [Also in Group XXIV] A cloth cutting device for sewing machines is driven by a driving member from the machine and has a cutter adapted to be put into operation or stopped during sewing operation by means of an operating lever a linkage system between the driving member and the cutter support being pivotable about two axes of rotation each of which is optionally adjustable by means of the lever, one for putting the cutter into operation and to vary the cutter stroke, and the other for raising and lowering the idle cutter. A cam 13 on the arm shaft 5 of the sewing machine is connected by a rod 14 to the centre of a bolt 21 the ends of which are each pivotally connected to the ends of links 22 and 23 respectively. The other end of link 22 is pivotally connected by a screw 24, which constitutes the first adjustable axis, to a crank 25 on a shaft 28 journalled in a housing, a lever 64 secured to the other end of the shaft being spring biased into engagement with the underside of a cam 62 rotatable by the operating lever 69. The other end of link 23 is pivoted at 29 to a lever 30 fast on a pivot shaft 32 constituting the second adjustable axis. A second lever 34, also fast on the pivot shaft is connected by way of a pitman 37 to the cutter support 43 which is reciprocable on a guide bar 41. The pivot shaft 32 is journalled in two bearing sleeves provided one at each of the lower ends of members 54 and 57. The upper ends of these members are pivoted about fixed points by the screws 55 and a shaft 59 respectively. A lever 58 secured to the latter is spring biased into engagement with the upper side of the cam 62. In the position shown in Fig. 6 the cutter is lowered, but as the axis of 24 passes through the pivot joint 29 the oscillation of links 22 and 23, due to the rotation of the cam 13, is not communicated to the pivot shaft 32 and the cutter remains stationary. When the key 70 of the lever 69 is raised, as shown in Fig. 5, the lobe of the cam 62 depresses the lever 64 to raise the axis of 24 above the pivot joint 29, the oscillation of the link 22 then causing oscillation of the lever 30 and the pivot shaft 32, and consequent reciprocation of the cutter support 43 with an amplitude depending upon the position of the lever 69. The lever 58 is unaffected by the raising of the lever as it is then resting on the concentric portion of the cam 62. On depression of the lever the cutter stroke is first reduced to zero and then the lobe of the cam 62 rotates the arm 58 to swing the pivot shaft 32 to the left as seen in Fig. 5, the lever 34 and pitman 37 thus raising the cutter support away from the work into an inoperative position. The Specification also describes how the distance of the axis of the shaft 28 from the axis of the shaft 5 may be chosen so that the movement of the cutter when the stroke is being changed may take place about the zero stroke position or upwardly or downwardly from that position.

Filed: 1929-06-26
Abstract: 314,400. Alloy Welding Processes, Ltd., (Assignees of Soudure Electrique Autogene). June 26, 1928, [Convention date]. Soldering; uniting by fusion. -A process for the manufacture of saline coating compositions particularly suitable for coating welding or soldering sticks or electrodes used for electric arc welding consists in forming a hydrogel by reaction between an electrolyte and a gel-forming compound, such as sodium silicate, in true or pseudo solution, and stabilizing the product by addition of an acid, base, or salt. Other substances, such as acids, bases, salts, oxides, carbonates, carbon, metals, &c. may be added to the product. According to one example, sodium silicate solution is treated with potassium fluoride, and the product is stabilized by addition of phosphoric acid. Sodium and potassium carbonate and sodium hypophosphite are subsequently added, and the resulting mixture is converted into a paste by the incorporation of an inert substance, e.g. siliceous earth. In another example, hydrofluoric acid solution is precipitated with sodium, potassium, and lithium chlorides and stabilized by addition of caustic potash. Sodium sulphite is subsequently added and the mixture converted into a, paste by addition of an inert substance.

Filed: 1929-07-01
Abstract: 335,903. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). July 1,1929. Residual gases; bulbs.-A concentrated incandescent body of tungsten is arranged together with mercury, or other substance vaporizing to give a gas indifferent to tungsten, in a bulb allowing the mercury to circulate, the distance of the tungsten from the bulb being not more than 0.4, and preferably 0.25, of this distance in the standard tungstenfilament, gas-filled lamp of the same wattage with a spherical bulb. A double helix 12 of tungsten may be arranged close to a drop of mercury 13 near the bottom of a bulb 11 with a cap 10 at the top and with walls 14 converging towards the helix 12. Mercury vaporizes at 13 and the vapour rises, the bulb near the helix 12 being thus cooled. The mercury condenses at the top of the bulb and flows down the walls 14, thus keeping them clear of evaporated tungsten particles. The size of the bulbs of lamps for projection purposes and for searchlights on aeroplanes is thus reduced. In modifications, the filament is a single helix and the bulb is cylindrical at its upper or lower end. The bulb may contain gases such as nitrogen or argon in addition to mercury and need not be exhausted to the usual degree, remaining traces of oxygen being made harmless by the mercury. Specifications 10918/13 and 17326/14 are referred to.
