Title: Improvements in brakes
IPC: B60T7/20
Filed: 1922-07-29
Abstract: 206,213. Cole, T. H. July 29, 1922. Actuated by backward pressure of tractor or relaxation of pull; actuated by springs and weights; force-transmitting mechanism.-Brake mechanism for trailer vehicles, of the kind described in Specification 188,845 whereby the brakes are automatically applied when the tractive force is relaxed is adapted to give a braking pressure dependent upon the load as well, it may be, as upon the gradient. The lever a, Fig. 1, pivoted at a<1> on a pin carried by a pair of rods b is connected bv the rod e<1> to one end of the brake application spring e, the other end of which is held by an adjusting nut f<2> provided with a handle f<3> and abutting against a fixed bracket f<1>. The lever a is connected at a<3> to the balance bar g the ends of which are connected by rods g<2> to levers d<1> mounted upon the bearing springs d<2> and adapted to apply the brakes. The rod h by which the brakes are taken off when the tractive effort is applied to the draw-bar i<1> is also con.. nected to the lever a. This rod is coupled to the frame i by a nut and screw device h<4> which has the thread removed at the sides so that the nut may be slid on to the rod and the threads on these parts be then engaged by a quarter turn of the nut. Lugs h<5> on the nut are adapted to abut against bars h<2>, h<3> on the forward section of the rod h in such a manner as to permit freedom for longitudinal movement of the rod. The rod is jointed at h<6> and is supported when uncoupled by a depending rod h<8>. To render the braking pressure dependent upon the load, the sliding or shackled ends of the springs d<2> are disposed forward so that the axle moves forwardly in relation to the body as the load increases and thus increases the tension of the spring e when the brake is applied. Fig. 2 shows an arrangement in which the brakes are applied by a weight movable along a lever as described in the prior Specification modified to render the braking pressure dependent upon the load. The weight k<1> is suspended by rollers from the lever k which is fulcrummed at k<2> on brackets ! l secured to the axle and has a vertical arm which is slidably engaged with the balance bar n suspended from the body by links n<2> and connected by rods n<1> and levers o<1> to the brakes r. Vertical displacement of the body due to variation of the load thus effects a corresponding variation in the effective length of the vertical arm of the lever k. Bowden cable connections for the brakes may be employed and in one arrangement for operating rear wheel brakes the Bowden cable extends from the point a<2> of a lever such as a, Fig. 1, to a horizontal lever pivoted upon the draw-bar frame. This lever is connected also to the pawl frame i and to the forward end of the brake application spring, the rear end of this spring being connected to the front member of the fore carriage. The abutment for the rear end of the cable may be provided on the front cross-member of the body.

Title: Apparatus for Testing Strenght
Inventor: UNSWORTH GEORGE DAVID
IPC: G01N3/08
Filed: 1966-05-13
Abstract: 1,185,024. Testing yarn electrically. WOOL INDUSTRIES RESEARCH ASSOCIATION. May 25, 1967 [May 13, 1966], No.21315/66. Heading G1N. In apparatus for determining the breaking strength of yarn, a predetermined length of the yarn is extended by a rod attached to a resilient lever carrying strain gauges, the rod being pushed by a cam surface at a constant rate whilst the stress is measured in a bridge circuit and recorded. The yarn is unusually located between a fixed jaw 14 Fig. 4 and two movable jaws 15, one on each side of the fixed jaw. The test is initiated by moving a lever 17 to the left as shown. This operates through cam plates 24<SP>1</SP>, 25 and cantilever 26 to move a hook 18 so that it pulls a small length of yarn into a U-shape between jaws 15. Lever 17 then operates a micro-switch 27 which energizes a coil 19 to clamp the small length of yarn between jaws 14, 15 by magnetic attraction, and causes subsequent further rotation of plate 25 through a clutch 33 and motor 28, whereby hook 18 stretches the yarn to breaking point. Two silicon crystal resistance stain gauges 32 are mounted on the cantilevers 26, measuring in a bridge circuit the stress exerted by the hook 18, the stress signal being fed to a recording chart driven by the motor 28. The apparatus may be calibrated to measure the yarn diameter by the change in inductance of coil 19.

Filed: 1966-05-13
Abstract: 1,138,309. Photographic camera. AGFAGEVAERT A.G. May 13,1966 [May 15, 1965], No.21409/66. Heading G2A. In a camera having automatic film threading means, there is provided a guide surface 11 at the edge of the picture gate 2 adjacent to the film take-up means 5, which guide surface intercepts the leading edge 10a of the film 10, which has moved into the gate 2, and returns it back to the film path 22. The guide surface 11 may be flat and extend obliquely into the film path 22 in the direction of film advance, or it may be concave in the direction of film advance. The guide surface 11 may be supported on a pivoted lever or levers and urged into its inclined position by a spring, the action of loading film then causing the surface 11 to become parallel to the film path. In Fig. 1 the surface 11 is urged into the inclined position by a spring 18 acting against a lever 17 which contacts a cam plate 19 connected with the exposure counter and, on turning the counter to its initial position, the cam and lever force the guide surface into the position parallel to the film path 22. In Fig. 3 (not shown), the film 10 passing over the surface 11 overcomes the action of a spring. In Fig. 4 (not shown), a feeler-pin projecting into the film path is depressed by the film 10 and causes a lever to turn about a pin thus causing the surface 11 to become parallel to the film path.

Signalling proximity of vessels.-A signal-circuit closer operated by the approach of a magnetic body, for example a ship, comprises two magnets arranged one above the other so as to rotate independently on a common vertical axis each carrying contacts so that relative rotation between the magnets connects the contacts and closes the circuit. As shown applied to a floating or submerged device oper. ated by the approach of a ship, the switch mechanism is contained within an inner casing 13 mounted on gimbals 11 within a shell. One magnet 25 of angular form is arranged at the base of a thimble 24, 26 supported on a pivot point 24<1> at the extremity of a post 22 carrying an adjustable nut which in conjunction with an internal flange, prevents the thimble falling off the pivot if the casing is reversed. An extension of the thimble above the pivot carries a cylindrical sleeve 44 and balanced contacts 31 spaced apart and in electrical connection with the thimble. Between the contacts 31 a central contact member 35 extends: it is mounted on a second thimble 33<1> supported by a pivot point 32 secured in the extension of the first thimble. In turn, an extension of the second thimble carries a pivot point supporting a third thimble 38 which is connected by a fine wire to the insulated terminal 47 on the casing the terminal being thereby connected to the contact member 35. The shell and the casing contain liquid such as oil, and floats 28, 29, 33, 39, take most of the weight of the thimbles off the pivot points. An internal flange 40 supported from the float prevents the third thimble falling off if the casing is reversed. In addition to the magnet 25 a second magnet 34 is provided carried by the second thimble 33<1>. The two magnets are permanently polarized and on the approach of a steel ship relative rotation of the two magnets ensues whereupon the contact member and one or other of the contacts come into engagement and close an indicating circuit.

Title: Safety device for projectile fuses
IPC: F42C9/14
Filed: 1924-09-11
Abstract: 221,822. Pantoflicek, B. Sept. 11, 1923, [Convention date]. Projectile fuzes.-A fuze or combination of fuzes or parts thereof are normally held in rear of the main charge of the projectile to prevent accidental transmission of explosion thereto, and move forward during flight to the operative position adjacent a directimpact striker. As shown in Fig. 2, two fuzes z<1>, z<11> are arranged in an axial tube 3, and are normally held away from the projectile charge 2 by a split pin 55, which is removed automatically when the projectile is discharged. The fuzes then creep forward against the plungers 50, 51 in the projectile nose 5. The plunger 51 is locked or freed according to the action desired. When the plunger 51 is locked, impact drives the plunger 50 against the firing- pin 30 of the detonator 31 of the fuze z<1>, and the flash from the detonator 31 is transmitted without delay by powder columns 33 to the doublecharge primer 38, 39. When the plunger 51 is not locked, the impact is transmitted thereby to the firing-pin 35, which fires the detonator 36 of the fuze z<11>; and the flash from this detonator is delayed by a patch 43. In a modification, only one fuze is used, its firing-pin takes the place of the plunger 50, and the plunger 51 is omitted ; only the detonator and the primer are then normally held at safe in the tail of the tube 3. The parts held at safe away from the main charge may. it is said, be easily removed, examined, and replaced. Specification 221,821 is referred to.
