Title: Improved means for stamping or post-marking letters, packages and the like
IPC: G07F17/26
Filed: 1938-03-24
Abstract: 496,531. Coin-freed postmarking or franking apparatus. SOUTHGATE, J. F. March 24, 1938, No. 9031. [Class 27] [Also in Group XVI] Means for stamping or postmarking letters, packages, &c., which may, if desired, be coinfreed, comprises a stamping member 1, Fig. 1, carried by a lever 2 which is rocked by a cam 3 operated by an electric motor or other means to cause the stamp 1 to move down on to a letter &c. inserted through a slot 12 to a platform 13, and then return to its initial position. The lever 2 has a roller 7 engaging the edge of the cam 3 which has a short drop 10 to allow the stamp 1 to contact with an inking pad 11 and an abrupt shoulder 9 permitting the lever 2 to move further down to frank the letter &c. The pad 11 is carried by a lever 15 pivoted at 16 to a bracket 17. It is moved out of the path of the stamp 1 by a rod 20 connected through a lost-motion spring coupling 23 to a link 18 which is pivoted at 19 to the face of the cam 3. The coupling 23 prevents movement of the pad while the roller 7 is on the cam portion 10 and also the return of the pad until the stamp 1 has returned to its initial position. The cam 3 in the machine shown is driven by an electric motor which is started by a coin-freed relay. The cam has projection 27, 28 which close and open respectively a main switch in the motor circuit. Coin action, weight and multiple-coin ; testing and returning coins.-A coin 32, Fig. 2, inserted in a shoot 30 depresses by weight a plunger 29 a contact 31 on which closes the relay circuit. Light coins fail to depress the plunger and are returned through a shoot 34. A member 35 pivoted to the plunger blocks the return shoot 34, when the plunger is depressed, to prevent a proper coin from passing therethrough. This coin rests on hinged flaps 36, which normally prevent the passage of a light coin through a shoot 33 to the money box, these flaps being opened by a wedge 41 on a lever 40 actuated by a projection 37 on a bar 38 which is connected by a link 39 to the cam 3. A second projection 42 actuates a lever 43 to raise the plunger 29 when the bar 38 moves downwards. Two shoots are provided for pennies and half-pennies the penny being inserted in the shoot 30. The plunger is prevented from being moved by the penny until a retaining catch is first tripped by a half-penny falling down its shoot. Registering.-A pawl 46 on the bar 38 actuates a counter 45 for each revolution of the cam 3.

Abstract: 604,366. Washing ores. AMERICAN CYANAMID CO. April 13, 1945, No. 9263. Convention date, April 21, 1944. [Class 82 (ii)] In a method of concentrating small fragmentary particles from a mixture, the mixture is subjected to an upward current of a medium of high density, but slightly less than that of the lighter fraction, in a series of vessels and the settled portions from each vessel are screened so that the smaller heavy particles are passed and the larger light particles retained. The heavy and light portions are collected and recovered as combined heavy concentrate and combined light concentrate. As shown, the feed is subjected to four separations in a heavy medium which has a magnetic solid phase, the first giving a heavy fraction only and the remainder producing progressively smaller heavy particles and larger, but progressively smaller, light particles. The settled mixed particles are screened, all the undersize particles being combined and all the oversize particles being similarly combined to give a heavy concentrate and a light concentrate. Both concentrates are separated from particles of medium in magnetic separations. In a modification Fig. 2 (not shown) the screen oversize is washed on the screen and no separation of medium from the light concentrate is required. The overflow from the final washing treatment may be separated from the medium and the non-magnetic portion subjected to further processes, e.g. grinding and flotation.
