Title: A new or improved mechanism for imparting rectilinear movement to a member in opposite directions
IPC: G05G25/00
Filed: 1948-12-17
Abstract: 661,678. Window-operating mechanism. BEATON & SON, Ltd., G., and YOUNG, F. C. Dec. 16, 1949 [Dec. 17, 1948], No. 32696/48. Class 20(iii) [Also in Group XXV] Mechanism for imparting rectilinear movement to a member such as a motor vehicle window, door, roof, bonnet, boot or folding head, comprises a pair of guide bars 1, 2, relatively inclined to each other, a pair of rollers 14, 16, engaging the bars and spring-operated means for urging the rollers and bars into contact. A window 12 is supported by a cradle 13 carrying the rollers and the bars are mounted on a base 3, bar 1 being free to swing about a pivot 5. In channel form it partly surrounds a notched bar 4 which is supported by pins 6, 7, in inclined slots 8, 9, in the channel. Roller 14 is mounted in a stirrup 17 biassed towards the right by a spring 18 anchored to the cradle. Depression of the bar by means of a handle portion 11 withdraws notched bar 4 from a waisted part of the roller which is thereby enabled by the pull of the spring to run up the track formed by the channel edges of bar 1, thus raising the window. On moving the handle within the slot of an escutcheon plate 2 away from the fixed bar 2 so that the bars converge downwardly the window descends when the handle is depressed to free the roller. A modification, Fig. 6, comprising two bars 33, 34 pivoted on pins 35, 36, has rollers 30, 31, urged by a connecting spring 32 against their outer faces, the bars being rocked into mutually convergent or divergent positions by a handle which turns a disc 41 with a cam slot 40, a stud 38 on an extension of bar 33 projecting through a slot 39 in an extension of bar 34 and the cam slot. A lever 46 having at its outer end a pin 53 engaging a slot 54 in the window cradle has an apertured boss surrounding the handle spindle 42 between which and the inner face of the boss a coiled spring is expanded to hold the lever frictionally against rotation, until by turning the handle slightly the end wall of a slot in the spindle presses against the inturned end of the spring which collapses sufficiently to release its grip and free the lever.

Title: Improvements in water cooled stirring windings for furnaces
IPC: F27D27/00
Filed: 1957-10-21
Abstract: 817,046. Electric furnaces. ALLMANNA SVENSKA ELEKTRISKA A.B. Oct. 2], 1957 [Oct. 30, 1956], No. 32747/57. Class 39(3) An electric furnace 2 has below it a stirring winding 1 normally cooled by water through supply pipes 4a, 4b, but in the event of risk of metal penetrating the furnace, a thermostat 8 adjacent its base operates means 13 actuating valves 5a, 5b to connect a compressed air supply 6 to the stirring winding 1 to drive out the water. The thermostat 8 completes an auxiliary circuit 9 comprising an alarm 12, a relay 10 operating a switch 11 to cut off current to the winding, and a motor 14, the starting of which is delayed by a time lag device 17. The motor moves a rack 15 and two pinions 16 connected to two-way valves 5a, 5b, which are rotated to connect valve 5a to the air supply and valve 5b to an outlet 7. When the water has been blown out, valve 5b may be closed. Air cooling may continue for a predetermined time. If the stirring winding is not hollow, water is passed through pipes in contact therewith. The winding may be a conventional coil winding, i.e. like the stator winding of a polyphase asynchronous motor or may comprise polyphase cylindrical windings slid on straight iron yokes. If the yokes have cooling channels, these are included in the compressed air system.

Title: Improvements in or relating to the distributing mechanism of typographical composing and distributing machines
IPC: B41B11/18
Filed: 1925-12-29
Abstract: 268,057. Linotype & Machinery, Ltd., and Drake, T. Dec. 29, 1925. Distributing matrices; magazines.-In machines having a number of distributors and a column of magazines, the distributors are arranged vertically one above another, and the magazine entrances, which are in overlapping relation, are so supported that an upper entrance may be moved out of operative position without disturbing a lower entrance. Each entrance, when opened, is arranged to throw out the distributor clutch. In the arrangement described, which is shown as applied to machines having main and auxiliary magazines side by side, each upper magazine entrance 22 is supported by studs 17 resting in forked lugs 18, and is held in operative position by a pivoted latch 19. The upper part of the entrance has partitions 20, and the lower part has matrix-guiding grooves, the lower ends of the partitions extending into the grooves. Each lower entrance 14 is movable about a pivot 26, and has partitions 27, which extend into the matrix-channels of the magazine. Each entrance can thus be separately opened. The distributors are stopped, when an upper entrance is opened, by means of an arm 29, which acts through a lever 31 and a cam on the distributor clutch. The main and auxiliary entrances are connected by overlapping bars, so that movement of either will operate the clutch. The lower entrances act on the clutch through a sliding rod 42, which is carried by the auxiliary entrance, and normally rests between a cam surface on the main entrance and a spring-pressed rod which operates the clutch.

Abstract: 662,651. Diaphragm pumps. DELMAN CORPORATION. Dec. 20,1948 [April 12, 1948] No. 32844/48. Class 102 (i) A diaphragm pump has a resilient diaphragm 28 positioned transversely of a casing 23 and actuated on its delivery stroke by a plunger 47, having a limited movement longitudinally of the casing, to a maximum flexed position within the pump chamber 38 in which it is substantially in a full bearing engagement with a convex head 56 of the plunger and means for returning the plunger to a position in which its head is out of engagement with the diaphragm when the latter is in its transverse place. The plunger is returned by a spring 54 which is fully compressed during the delivery stroke to limit the inward movement of the plunger. Liquid from a reservoir is drawn into the pump chamber through an inlet 42 and is delivered through an outlet 43 both of which have one way valves 44. The pump which is intended for supplying clearing liquid to the windshields of automobiles is preferably mounted on the floor thereof and is foot operated. Liquid is delivered to a twin jet nozzle on the windshield.
