Filed: 1932-11-07
Abstract: 396,967. Coin-freed safes. SAMANIEGO Y GONZALO, J. M., 5, Plaza de Fermin Galan, Madrid. Nov. 7, 1932, No. 31341. Convention date, Nov. 7, 1931. [Class 27.] A coin-freed locking mechanism for a safe, in which valuables may be deposited temporarily, comprises a door bolt 1 to engage a socket 1a on the safe, a number of letter bearing discs 2 being mounted coaxially with the bolt and revoluble on fixed bearings 3 which have key-ways 3a to allow radial projections 6a on the bolt to pass. A disc 4 is slidably mounted on a fixed bearing 5 adjacent each disc 2, each disc 4 having a key-way 4a with which a projection 6a engages to prevent rotation of the disc when the bolt is retracted. The discs 4 are moved by forks 7 on a coin-actuated spring-controlled rod 8 and carry pins 9 to engage in holes 10 in the corresponding discs 2 when the rod 8 is moved to the left by its spring 7a. A coin inserted in a slot 11 by engaging ramps 12c, 8a retracts a second bolt 12 and moves the rod 8 to the right to disengage the discs 4 from the discs 2. The bolt 12 is held retracted by a catch 15 and the rod 8 by a spring catch 14 mounted on the bolt 1. The bolt 1, which is normally retracted by a spring, is then shot by a hand-operated member 13 and the discs 2 revolved to a new combination of letters. The rod 8 is released by a pin 14a on the catch 14 engaging a ramp 14b, and when it moves to the left the discs 4 are clutched to the discs 2. Since the projections 6a on the shot bolt are free from the key-ways 4a, the discs 2, 4 can now be rotated to conceal the combination, and by means of the key-ways 4a to lock the bolt in its shot position. A second catch 19 on the bolt 1 coacting with a ramp 19b also locks the rod 8 in its innermost position. To unlock the safe, the discs 2, 4 must first be turned to show the proper combination of letters. The retaining catch 15 of the bolt 12 is released simultaneously with the closing of the safe door. In safes controlled by more than one proprietor, the bolt 1 is retained in unlocked position by a spring catch 18, and a coin must be inserted in a second slot 17 before the bolt can be shot. This coin releases the catch by lifting a lever 18a. The coins inserted in the slots 11, 17 are conveyed to separate receptacles. Coin-slit closing-devices.-When the bolt 1 is shot, the slot 11 is closed by an arm 20 bearing the word " Hired."

The link is then seized by pincers above and below, and the lower set given a partial rotation to twist the link, whereupon the upper pincers are released and the lower set move the link downwards so that the wire for the next link is fed through it. The wire is fed through a split horn 5, Fig. 7, against a stop 6, and a cutter 34, having a helical movement to bring it to the operative position, cuts off a length. A mandrel 50 is pushed into position, and arms 7, 8, Fig. 8, are moved forward to bend the wire into U-shape round the mandrel. A pair of horizontally-moving levers (not shown) then bend the ends of the U round the mandrel to complete the link as shown in Fig. 9, and the ends are then struck by a hammer 44 which has a helical movement similar to the cutter 34. The link is then seized by an upper pair of pincers 26, operated by a pointed rod 31, Fig. 5, and by a lower pair 61, which are given a slight rotary movement by rack-and-pinion gear to twist the link. The link is then released by the upper pincers, and the lower ones 61, are given a downward movement to depress the link so that the wire to form the next link is fed through it. All the movements are effected through levers by cams on a main shaft which may be driven through gear from a shaft with fast and loose pulleys as usual.

Abstract: 1,113,352. Connectors for coaxial cables. BENDIX CORPORATION. 26 July, 1965 [3 Aug., 1964], No.31817/65. Heading H2E. Two coaxial cables 11, are interconnected through a coupling member which comprises two insulating body members 17 and 18, which support a central tubular conducting element 21, and are located within an outer screwthreaded casing 5. The element 21 has a larger diameter than the central conductors of the cables and consequently the outer casing is manufactured with a correspondingly larger diameter than the outer conductors of the cables to avoid any change in characteristic impedance of the line. The outer casing has a slightly longer axial length than the inner element to introduce short sections a of the line between the transverse planes of adjacent steps in the inner and outer conductors which sections of high impedance function as series inductances and prevent increases in the voltage standing wave ratio. The electrical connection between the casing and outer conductor is via ferrule 23 which is soldered at 24 to the outer conductor. The cables and conducting member are drawn together by nuts 6. In a modification, particularly for use with flexible cables, Fig. 2 (not shown), the tubular casing has a tapered extension which fits between the cable insulation and conductive braid and is held by a tube 36 which is crimped in position.

Abstract: 808,865. Rolling profiles. GROB, E. Oct. 22, 1956 [Oct. 22, 1955], No. 32106/56. Class 83 (4). In a method of profiling metal bodies in which forming rolls 9, 10, 11, Fig. 10, on rotating carrier heads 12, 13 are brought into repeated engagement with the work W, the different rolls carry out different operations on the workpiece. In forming a toothed profile the rollers 11 on the carrier 12 form a rough tooth shape while different rollers 9, 10 of a second carrier 13 form the flanks and the tops of the teeth respectively. The carriers are staggered axially along the work so that the grooves are formed progressively. Profiled rollers 3, which are idly rotatable on axes parallel to the work act as supports for the work. The rolls 3 may be spring loaded axially to permit the work to be fed continuously during intermittent engagement by the rollers. In rolling profiled bodies with an odd number of teeth the rollers 7a, 7b, Fig. 3, may be offset from the work axis and with even number of teeth the rollers 8a, 8b, Fig. 5, may have two work-engaging portions to engage left- and right-hand flanks and balance the torque applied to the work. In progressively forming splines the initial triangular tooth form 4, Fig. 4, followed by a final tooth form 5 ensures a progressive flow of the metal over the profile.
