Title: Improvements relating to vehicle wind screen wipers
IPC: B60S1/40
Filed: 1945-11-26
Abstract: 604,483. Windscreen wipers. LUCAS, Ltd., J., HAWKESWOOD, R. W., and PURDEN, R. H. Nov. 26, 1945, Nos. 31799/45 and 8141/46. [Class 138 (i)] An oscillatory vehicle windscreen wiper comprises a main arm, a sub-arm attached at one end thereto and having a limited range of pivotal movement relative thereto, and in the plane of movement thereof, and adapted to be attached at the other end to the wiper blade. In one form, Figs. 2 and 3, the main arm a and sub-arm e are loosely pivoted together by a pin d so that the arm e can move angularly relative to the arm a to an extent limited by stops j formed in a protective metal piece 7c secured to the arm a, and can also pivot slightly in a plane at right-angles to the screen. Two projections m of a metal strip n on the arm e extend towards the main arm, one projection m engaging between a stop and an abutment o of a metal piece p on the arm a, so that the arms are substantially locked together. In operation, at the beginning of a stroke, the drag of the screen on the blade causes the arm e to pivot in a plane normal to the screen, releasing the projection m from the abutment o, and then causes the arm e to pivot about the pin d until the other projection m engages between the other abutment o and stop j, locking the arms in the opposite position. In a second form, Figs. 5 and 6, the arms a, e are locked by one of two projections t in a plate r pivoted at r<SP>1</SP> to the arm a engaging one of two apertures u in the arm e. Towards the end of each stroke, one of two bent-over portions x of a lever v pivoted at w to the arm a abuts a fixed stop, whereby a bifurcated portion of the lever v embracing the plate r pivots the plate r to release the arm e, an over-centre spring s then tending to continue the pivoting movement,.until on reversal of the stroke the arm e is caused by the drag to pivot about the arm a until the other projection t engages the other aperture u to lock the arms in the alternative position. In a third form, Fig. 7, the arm e has a metal piece y with in-turned flat edges z, one of which engages the flat head 4 of a locking member 2 slidably attached to the arm a and having one end abutting a stationary cam 5. During a part of each stroke, the cam 5 allows the member 2 to be retracted under the action of a spring 6, whereby the arm e is released and pivots relative to the arm a until the member 2 engages the other edge z, locking the arms in the alternative position. All of the forms described result in the blade resting flat against the edge of the screen when the wiper is in a limit position, owing to the inclination between the arms a, e, while preventing undesirable or premature pivoting between the arms. Specification 578,353 is referred to.

Title: Improvements in automatic temperature control systems for electric heating appliances
IPC: H01H35/26
Filed: 1939-12-08
Abstract: 539,481. Thermal switches, snap-action switches. AMERICAN THERMOMETER CO. Dec. 8, 1939, No. 31846. Convention date, Dec. 23, 1938. [Class 38 (v)] [Also in Group XXXV] A single control handle is arranged to determine whether a "broil" or a "bake" element shall be operative in an oven and to adjust a thermostat controlling the circuit of those elements. Both elements may be rendered effective to raise the temperature quickly to that desired, whereupon the thermostat operates to disconnect the "broil" element leaving the "bake" element only under its control. An expansible diaphragm 11 connected with a bulb in the oven and adjustable to determine the control temperature by a rotary dial 8, operates upon an element 16 of a snap-action switch comprising contacts 43 in the main circuits supplying a "bake" element 102, through a normally-closed switch 92, and a "broil" element 99, through contact 55 of a second snap-action switch. This switch may be closed manually, and at any but the maximum temperature setting of the dial is opened by the diaphragm 11 simultaneously with the first operation of the main switch, subsequent heating being confined to the "bake" element under the control of the thermostat. A member 71 transmits the thrust of the diaphragm from the main switch contact arm 28 to the control arm 59 of the broil switch except when the dial has been set to a maximum position marked "broil." In this position a cam on the back of the dial operates a rod 80 carrying a wedge causing withdrawal of the member 71 against a restoring spring, the actuation by a member 81 of the "broil" switch to closed position, and the actuation of a rod 94 to open the "bake" switch. With the dial left in this position the broil element is alone operative but subsequent return of the dial to any temperature setting produces the action already described. In a modification the rod 80 is operated by pressure upon the dial at any temperature setting.

Abstract: 383,420. Bending wood. SCHLESINGER G., 171, Berlinerstrasse, Charlottenburg, Berlin. Nov. 17, 1931, No. 31849. Convention date, Nov. 26, 1930. [Class 145 (ii).] In a process and apparatus for producing cup-shaped bodies from single or multiple-layer blanks of wood by means of coacting cylindrical dies 3, 7, pressure i s exerted on the edge of the blank during its passage through the cylindrical part 5 of the fixed die 3 and also previouslv in the inlet 4 to the die 3. This peripheral pressure is exerted by segments 13 mounted on the die 7 and spring-pressed radially outward so as to engage the edge of the blank. The conical part 4 of the die 3 causes the segments 13 to be compressed inwardly as the die moves downwardly so as, preferably, to form a complete ring engaging the edge of the cup-shaped body produced and thus preventing splitting or cracking of the edge of the blank. The blank is supported by a counterpressure member 6 during the shaping operation. Slots of the same depth as the required flange may be provided on the edge of each blank to facilitate the shaping operation. According to the Specification as open to inspection under Sect. 91 (3) (a), the peripheral pressure may be applied only when the blank has entered the cylindrical part 5 of the die 3. This subject-matter does not appear in the Specification as accepted.

Abstract: 624,379. Moulding artificial teeth. HAWTIN, F., and HAWTIN, E. W. Oct. 31, 1946, No. 32398. [Class 87 (ii)] [Also in Group XXII] A mould for making artificial teeth is made by forming a series of patterns and moulds. A two-part plaster cast is made between brass plates, 2, 3 around a pattern tooth 1, Fig. 1, the tooth, which may have been dusted with graphite to facilitate removal, is then removed. A plate 11, Fig. 2, is placed between the plates 2, 3 and the aperture 13 filled with wax through a channel 14 to form a wax pattern 15, Fig. 3. The pattern is invested in a pot of heat resistant material, which may be a resinous body in a spirit solvent, and the wax then removed to leave a mould. A pattern of metal, e.g. zinc, is then formed in the mouid, and the mould removed. The zinc pattern is placed between plates similar to or the same as the plates 2, 3, and metal, e.g. printers' metal, is cast in the cavities 4, 6 to form metal mould sections. The zinc pattern may be first dusted with graphite. The pattern is removed, an apertured plate 11 placed between the mould sections, and then a Wood's metal pattern is cast by pouring the metal into the aperture 13 through the opening 14. Several Wood's metal patterns 23a, Fig. 11, are then placed between steel plates 25, 26 having through holes 28, 31 and the plates clamped together. The assembly is placed in a metal plating bath to cover the tooth embossments 24 and the insides of the holes 28, 31 with metal, e.g. nickel. The assembly is then placed in another bath to deposit another metal, e.g. copper, the surface of which may be roughened by sand-blasting, on the first metal. Metal, e.g. carbon steel, or a thermosetting synthetic resin impregnated with metal, e.g. copper, is then sprayed into the holes to fill them to the level of the plates 25, 26. The inside and outside faces of the plates 25, 26 are then made flat and a final coating of metal, e.g. hard chrome, applied to the mould impressions and the inter-engaging faces of the plates. The plates 25, 26 are then assembled, between bolsters 35, 36, to form the mould cavities 41, Fig. 12. The several Wood's metal patterns may be made separately from the printers' metal mould or a series of zinc patterns may be made and these patterns assembied together, e.g. in a circle, to make a series of printers metal moulds, from which a series of Wood's metal patterns would be made in one operation.
