[Classes 16 and 146 (ii).] A manifolding tablet or block comprises at least two sheets of paper joined together at their edges and having on their outer faces indications of the lines or zones to be written upon or otherwise marked, and reproducing means between the sheets, the lines or zones on one side being out of register with those on the other side of the block and the reproducing means being disposed to effect reproduction only on the inner face of the underlying sheet of writing &c. applied to either of the outer faces of the block. Two sheets 2, 3 may be glued to the inside of a double frame or folder and in the interspace a third sheet 5 may be interposed between two sheets of carbon paper 6, 7 ; the block is completed by gumming together the edges 8 of the frame, and lines of perforations 9 are provided along which the marginal portion of the block may be torn away to free the three copies. Instead of using a frame the two outer sheets may be in a single piece, or two separate sheets may be used, and small gummed flaps are provided to secure them together. The block may comprise sheets sewn together, and clasps, pressbuttons, or lead seals may be applied to guarantee its intactness. The carbon sheets may have on each side reproducing strips or zones alternate with non-producing strips or zones so disposed that a reproducing strip on one side corresponds with a non-reproducing strip on the other side of the sheet, the strips or zones being shaped and dimensioned to correspond with the writing spaces on the outer faces of the block. Carbon papers may be replaced by coatings on the backs of the sheets. When used for telegraphic or postal services the parts of the block may be separated by an official; one part can be forwarded in an envelope as a 'letter or given to the telegraph department and another part can be given to the sender as a receipt. When used for postal services each of the separated sheets of the block may be further provided with a gummed edge strip separated from the main portion of the sheet by a line of perforations so that one of the copies may be folded, sealed, and forwarded as a letter to the addressee. The sheets comprising the block may have the shape of a postcard and on separation one of the sheets may be sent as a postcard. An alternative arrangement for postal purposes comprises a reply block for guaranteeing authenticity of reply which may be provided with means such as four extensions on one of the sheets of the block, such extensions being folded and gummed on the correspondence sheet which is to be forwarded with the block, which sheet has the address on the exterior and correspondence on its interior.

Title: An improved turret for a capstan or like lathe
IPC: B23Q16/10
Filed: 1947-10-25
Abstract: 628,451. Lathe details. JEAVONS, K. C. Oct. 25, 1947, No. 28580. [Class 83 (iii)] [Also in Group XXIV] A turret for a lathe comprises an actuating handle 28 movable between limits corresponding to the index angle and connected through a one-way clutch 53, 54 to a rotatable intermediate member which is connected in turn by spring means 43 to a tool-holder 11, whereby the latter is biassed to catch up with the angular movoment of the intermediate member; this movement of the latter acts through cam means 38, 39 so as, initially, to allow relative axial movement, under the action of biassing means, between the tool-holder 11 and a base member 15 and the consequent disengagement of one or more spring-pressed locking plungers 41, and, subsequently, to return the tool-holder 11 axially and allow the plungers 41 to re-engage when the tool-holder reaches the new indexed position. The tool-holder 11 is rotatably and slidably mounted on a sleeve 13 which is rotatably mounted on a vertical shaft 14 secured to the base member 15. The support 25 is fast with the ratchet-wheel 53 and thrust portion 52, which together constitute the intermediate member, and the ratchet-wheel 53 is connected by pawls 54 with a rotatable ring 55. The actuating lever 28 is journalled on the shaft 14 and has a slot 27 for engagement with an upstanding arm 26 on the ring 55; the angular movement of the lever 28 is limited by stops, and a spring tends to hold the lever against one of these stops. Upstanding camfollowers 38 on the member 25 co-operate with cams 39 on the underface of a stationary member 23. In the locked position of the toolholder, the cams 38, 39 so engage as to depress the latter through ball-bearings 56 and against the action of a spring 40; plungers 41 in the base 15 then engage holes 42 in the tool-holder. When the lever 28 is turned, the support 25 is driven through the ratchet-wheel 53 and pawls 54 so as to rotate the sleeve 13 with respect to the tool-holder, and, following upon the disengagement of the cams 38, 39 and the subsequent unlocking of the plungers 41, the toolholder is caused by springs 43, Fig. 3, connected between it and the thrust portion 52 to catch up with the support 25. During this movement, the tool-holder is accurately located with respect to the sleeve 13 by the engagement, under the action of the spring 40, of teeth 46 fast with the tool-holder with recesses 45 in the sleeve 13. Towards the end of this movement, the cams 38, 39 again operate to depress the tool-holder against the spring 40, and the plungers 41 snap into the holes 42 at the end of the indexing movement: Each pawl 54 has a portion of non-circular cross-section guided in a boss of similar cross-section in the ring 55. The cams 39 are so mounted in the support 23 as to permit of adjustment for wear.

Title: Improvements in and relating to automatic mount flashing machines
IPC: H01K3/02
Filed: 1947-10-31
Abstract: 631,079. Making electric lamp filaments. BRITISH THOMSON - HOUSTON CO., Ltd. Oct. 31, 1947, No. 29132 Convention date, Nov. 2, 1946 [Class 39(ii)] Electric incandescent lamp filaments mounted on stems are flashed automat .cally by supporting them in a series of heads in a carrier which is indexed through a number of work stations, each head having a pair of resilient fingers which are moved i n t o mechanical and electrical connection with the lead-in wires when the head arrives at a particular station at which it is raised into a chamber containing reducing gas, and at the same time an electric circuit is completed through the lead-in wires, this being continued for a predetermined time until the head is again lowered. Preferably the heads are mounted adjacent to the circum- .ference of a rotary turret which is indexed past a series of loading stations. Each head comprises a metal push rod 7 which is movable vertically relative to the face of the turret 2 and is shaped to provide, in co-operation with a vertical portion 8 of an insulating body 9, a stem holder which is slotted to receive the exhausting tube 11 of a lamp mount 14. A pair of divergent; surfaces 11a 11b is also formed to engage the. lead-in Wires 12, 13 of the mount, and an insulating flange or collar forming part of the body 9 is surrounded by a metal collar 15 which is secured to the flange by screws 16, 17. A pair of slotted rods 18, 19 on opposite sides of the rod 7 and movable vertically within the flange support resilient fingers 22, 23 arranged to engage the lead-in wires when in the operative position with the rod 7 elevated as shown, otherwise, with the rod lowered, shoes 26, 27 on the bottoms of the rods engage the surface of the turret, thereby compressing helical springs around the lower ends of the rods. The contacts 22, 23 are then disengaged from the lead-in wires. As shown the head and mount are within an arcuate chamber 30 disposed around a portion of the circumference of the turret, in which position a part of the edge of the collar 15 bears upon an insulating ledge 34 positioned along a part of the wall of the chamber 30, the ledge providing a support for a conductive plunger 35a. A circuit is thus completed through the metal collar 15, screw 16 and rod 18 to the lead-in wire 12 and thence through the filament, which is thereby heated while the head is located at station D, Fig. 1 (not shown). A similar heating may be effected by providing a conductive plunger at one or more subsequent stations. Hydrogen is admitted to the chamber 30 through a pipe 31. The head is subsequently lowered by a collar 38 acting on a collar 37 at the lower end of rod 7 under the control of a cam.

Abstract: 831,655. Interrupters. MIDGLEY, A. H. Sept. 23, 1957 [Sept. 24, 1956], No. 29143/.56. Class 38 (5). A switch comprises an interrupter cam for periodically opening and closing the contacts and a manually-operable cam for adjusting the contact gap, auxiliary cam means controlling the contact gap under the control of an electric motor or clock mechanism so that current may be supplied at a high rate for a period determined by the setting of the auxiliary cam means, the current being reduced to a lower value at the end of such period. The contact 1A is operable by the interrupter cam 1, and the contact 6A is controlled by the manually-operable cam 6 and the auxiliary cam 7. Cam 1 is driven by the motor (not shown) via gearing 3, 2, 46 at 1 r.p.m. and is mounted on a shaft 34 fixed to a square section shaft 5. Cam 6 is fixed on shaft 5 which carries a setting dial 14 and clutch plates 9, 11 cooperating with a fixed end plate 10 to hold the cam 6 in adjusted position. The cam 7 is carried by a sleeve 18 freely rotatable on a sleeve 8 carried by the shaft 5, the cam 7 being rotated by a gear 19 which is also mounted on the sleeve 18 and which is connected to the motor via gears 21, 22, 3, 2, 46. The gear 19 is connected by a pin 20 passing through slots in end plate 10 and dial 14 to an adjusting knob 17, and only has teeth on half its circumference. The period of make in a cycle is adjusted by the knob 14 and cam 6, and this is modified to give the temporary high rate by setting cam 7 relative to cam 6 to a position where contacts 1A, 6A are held closed. The motor then drives cam 7 back until the toothless part of gear 19 reaches gear 21, at which point cam 7 stops and the contacts are then only under the control of cams 1, 6. The cams 1 of several switches may be linked by chains or belts (Figs. 4, 5, not shown).
