Title: Improvements in and relating to intercommunication telephone systems
IPC: H04M1/52
Filed: 1919-07-22
Abstract: 152,917. Bygrave, L. C. July 22, 1919. Mechanically released switches. - In selector switches for intercommunication telephone systems, such as the system described in Specification 140,561, [Class 40 (iv), Telephones &c.], a rotary contact arm g is moved over a ring of stationary contacts h by a knob a to select the required circuit and the knob is depressed against a spring to complete the circuit. The depressed contact is locked against turning by the interengagement of a projection formed on the moving part with a depression on the stationary part or vice versa, or by the arm snapping down 'between two adjacent contact studs when an attempt is made to turn it. The contact is also locked against axial movement by the engagement of a bent rod i with a groove formed on the shank of the knob. The parts are unlocked by replacing the telephone in the cradle j. The apparatus is fitted with a pointer b preferably of springy or sliding construction to allow for the depression of the knob. Additional contacts k and l are operated by the knob and the locking rod respectively in order to carry out any required circuit changes.

Abstract: 1,044,439. Making hose clamps; bending metal; work-holders. C. E. MEESE, R. R. MEESE, N. M. STREB, and J. M. STREB. Feb. 10, 1965, No. 5791/65. Headings B3A, B3B, B3E and B3T. In a method of making a core die for forming hose clamps, the shank 2 of a workpiece is mounted in a lathe chuck and a cylindrical end portion is formed. The upper half of this portion is milled away leaving a portion 5 which is then provided with keyway and a keyed block 40 (Fig. 13, not shown) is secured thereto by a screw 20. After machining the block 40 to a semi-cylindrical shape (Fig. 12, not shown), the workpiece is placed in a jig 30 (Fig. 10, not shown) and is displaced on either side of the centre line to machine arcuate surfaces 51, 52 and 53, 54 to approximate size. The part 50 thus formed is removed and arcuate surfaces 10, 11 are machined on the portion 5 by setting off-centre in the jig 30 (Figs. 18-19, not shown). The part 50 is replaced and the arcuate surfaces 51, 52 and 53, 54 machined to final size. To blend the surfaces 53, 11 and 51, 10 the workpiece is rotated in the jig 30 by a small amount since the centres of the machined arcs lie below the centre line of the workpiece. Finishing operations involve machining a chamfer 3c on the flange 3. A hose clamp is formed from wire around the die in a four slide machine. A cut wire blank 70 (Fig. 27, not shown) is formed into a U shaped around the surfaces 10, 11 and tools 75, 76 (Fig. 25, not shown) form the wire around surfaces 51, 53. The upstanding ears 73b, 74b are formed by a tool 77 (Fig. 26, not shown).

Title: Improvements in or relating to automatic winding machines
IPC: B65H54/26
Filed: 1959-02-20
Abstract: 917,676. Winding yarns. REINERS, W. Feb. 20, 1959 [Feb. 28, 1958], No. 5904/59. Addition to 892,614. Class 120 (2). The automatic multi-station thread winding- machine claimed in Claim 21 of the parent Specification is modified in that the socket 51, for receiving the rod 31 to arrest the travel of tender 5, is formed in an elongated boss on, and extending longitudinally of, the bearer 4 and along which the rod is slidable in either direction of the relative movement of the tender and winding stations. As shown in Fig. 4 the socket 51 on bearer member 4 is formed in an elongated boss 51a which extends on both sides of the socket. It is thus possible for the rod 31 to be depressed so that it engages the top surface of boss 51a before it registers with the socket 51 to locate the tender. This is done by providing a resilient connection between the rod 31 and its operative lever. The arrangement is such that the distance b, Fig. 3, that the rod 31 has to move to engage the top surface of boss 51a is less than the distance a that the latch lever 30 has to move to release control disc 32 but the total distance b + c that the rod 31 can move when in register with the socket 51 is greater than the distance a, so that the control disc is released and the tender arrested at the same time. The rod 31 is formed with a conical end 31a and the socket 51 is correspondingly coned to ensure accurate positioning of the tender. In the enbodiment of Fig. 5 a pair of electrical contacts 110, 111 is mounted on arm 23 at each winding station while a pair of contacts 112, 113 is mounted on tender 5 so as to be engageable therewith when the tender is positioned with rod 31 in the appropriate socket 51. Contacts 110, 111 are in circuit with a pair of switch contacts, 114 on arm 23 and 115 on pivoted feeler member 17, a current source 116 and an electromagnet 117 the armature 118 of which is connected to latch lever 30. Should a fault occur, feeler 17 will rock to the chain-line position 17<SP>1</SP> and close contacts 114, 115. When thereafter the tender 5 arrives at the winding station the circuit will be complete through contacts 110, 112 and 111, 113 and the electromagnet 117 operated. Latch 30 will thus be pulled down so that the tender is arrested by member 31a engaging socket 51 and the notched disc 34 and thus the control disc 32 released to bring about the fault-eliminating operation. Once the fault is repaired the feeler 17 is returned to the full line position thereby opening contacts 114, 115 and permitting the latch lever 30 to return. In a further embodiment air suction means are used to move the rod 31.

Abstract: 491,157. Photographic cameras provided with exposure meters and viewfinders. KODAK, Ltd. Feb. 27, 1937, No. 5946. Convention date, March 23, 1936. [Class 98 (i)] A photographic camera adapted to receive interchangeable objectives has a photo-electric exposure meter and a pair of indicating members, one of which is actuated by the photoelectric cell to give an indication corresponding to the intensity of light incident on the camera objective, while the other is operable by a cam on a diaphragm adjusting member associated with the objective, the diaphragm being set for correct exposure when the indicating members are coincident. As shown a kinematograph camera 1 has a lens mount 2a with focusing ring 2b. The housing 5 contains a cellular baffle and a photo-electric cell connected to the coil 10 rotatable in the field of a magnet 11. A pointer 12 on the coil shaft moves over a transparent or translucent plate 13 carrying a scale 14 of stop values. The camera has a direct vision view-finder built into the carrying handle 15. The eyepiece frame 16 has a slit 24 and a lens 17 slidable downwardly by knobs 33 guided in slots 34. An auxiliary frame 18a for the object lens 18 is pivoted at 18b at the top of the carrier 19. A prism 23 brings the pointer 12 and its scale 14. into the field of vision of the operator through the slit 24. An opening is provided in the front of the housing to illuminate the scale 14. A spring-raised pointer 25 coaxial with pointer 12 and in front of the plate 13 has an extension 27 bearing on a cam 28 integral with the diaphragm adjusting ring 29 which is operated by a knurled lug 30. The pointer 25 is kept coincident with pointer 12 to correct the diaphragm opening for existing light conditions. A mask is placed over the front of the housing 5 if a slower speed film is used. The detachable fastening for the objectives may be of the bayonet lock type. In using a telephoto lens, the view-finder object lens is swung into inoperative position and the eyepiece lens is lowered, the scene being observed through two sight openings without lenses. Each objective is provided with a suitable cam 28. Specification 395,808 is referred to.
