Title: An automatic vending machine
IPC: G07F11/16
Filed: 1960-06-09
Abstract: 899,321. Coin-freed vending apparatus. TREMOLADA, G. June 9, 1960 [June 16, 1959], No. 20394/60. Class 27. Coin-freed apparatus for vending articles, such as beverages in bottles B stored in compartments 2-6 of adjustable width and length, has electro-hydraulic means for releasing articles from selected columns. The bottles B are stored in staggered double vertical rows in each compartment and are supported by a cross-bar 10 which lies under the vertical axis of one row and, when moved sideways by a double-acting hydraulic cylinder 17, releases the lowermost bottle of that row and engages under the lowermost bottle of the other row. The cross-bar has a roller 13 running on a rail 11 and a sleeve 14 sliding on a rail 12. The cylinders 17 for each cross-bar are connected to a central valve body 8 having five slide valves 25 moved in one direction by a solenoid 26 and returned by a spring. The valves are radially arranged and work in a common chamber 27 to which pressure is supplied by a pump 36<SP>1</SP>. An inserted coin closes a switch 40, Fig. 7, to energize a relay 41 and current is supplied to a set of pushbuttons 43 and to a set of relays 48. By depressing a selected pushbutton, a corresponding relay 48 is energized so that a switch 51 opens and cuts off the current to the other pushbuttons, a switch 49 is closed to energize the pump motor 36 through a pressure cut-out 153 (and also close a holding circuit for the relay) and a switch 50 is closed to send current to switches 52 in all the relays 48. The switch 50 is designed to close its associated switch 52 if the latter is open or to open it, if closed, but the switches 52, other than that corresponding to the depressed button, are not supplied through their associated switch 50 and only the one switch 52 will change over and the others will remain in the same position as they occupied at the end of the previous operation, either open or closed. The solenoid 152 corresponding to the switch 52 that has changed over will be either energized or allowed to remain de-energized so that the supply and discharge of fluid to a cylinder 17 will be reversed as compared with the previous operation and the cross-bar will be removed to release one bottle. The other cylinders are supplied with pressure in the same sense as during the previous operation and will remain stationary. When the crossbar has moved fully, the pressure of the pump rises and the cut-out 153 opens to stop the pump and cut off current to the control circuit. As shown in Fig. 7, two pushbuttons control the supply of two different beverages from three and two compartments respectively and the solenoids corresponding to compartments in these two sets are brought in successively by switches 154, 155, 156, 158, 159 operated as a compartment becomes empty, the last switch to operate illuminating an indicator lamp 160 or 161. A switch 157 energizes through the switches 158, 159 a solenoid 162 which blocks the coin slot or causes inserted coins to be returned.

Title: Improvements in and relating to lift safety devices
IPC: B66B5/00
Filed: 1950-08-18
Abstract: 694,116. Actuation of switches. FOTHERGILL, J. R. Aug. 17, 1951 [Aug. 18, 1950], No. 20513/50. Class 38 (v) A switch adapted for use as the combined ultimate main limit switch and isolating switch in the circuit of a lift, crane, hoist or like mechanism, has a member which may be released from the switch and used to gain access to enclosed parts of the circuit only when the switch is off. The switch has fixed contacts 14a which co-operate with moving contacts 14b mounted on a shaft 30 carrying a cam 34. A pawl 42 has an arm 42a, which is biased by a spring 44 into engagement with a segment 34a of the cam and holds the contacts closed. Should the lift overrun, a part of the lift engages a projection (not shown) on a cable 22 to rotate a pulley 20. A cam profile 50 on the pulley moves a push rod 48 to turn the pawl 42 so that its arm 42a is moved away from the segment 34a, whilst a projection 42b of the pawl positively rotates the cam 34 to open the contacts 14a, 14b. When the switch is used as an isolating switch, the depression of a spring-loaded push rod 46 effects the rotation of the pawl 42 to open the switch. The switch is reclosed by means of a handle (not shown) secured to the shaft 30. The cam 34 also has a segment 34b, which when the switch is closed, is engaged in a slot in the barrel 52 of a lock 18, the segment preventing the rotation of the barrel which is necessary before the member or key 19 can be removed from the lock. When the switch is opened and the circuit isolated, the segment 34b moves out of the slot and the key 19 may be turned and removed from the lock 18 to open a lock on the casing of a control panel (not shown).

Abstract: 890,375. Screw-cutting attachments. MORDUN ENGINEERING Ltd. June 29, 1959 [June 28, 1958], No. 20811/58. Class 83 (3). In a holder for screw-threading tools, e.g. taps, for use in a machine-tool, the tool is held against rotation during screwing by co-operating dogs on two axially movable members, the dogs being disengaged to allow the tool to rotate with the work when the required length of thread is reached, the member also having a cam or ratchet engagement which stops the tool rotation to unscrew the tool from the work when the direction of rotation of the work, and the axial feed of the tool are reversed. The holder comprises a flanged sleeve 1 non-rotatably fixed in a lathe turret &c., a member 3 carrying a tap or die 5 axially slidable and rotatably supported by the sleeve, and having dogs 9 co-operating with dogs 7 on the sleeve. A cam 19 on the sleeve co-operates with a peg 20 in the member 3. In operation, the holder with dogs 7, 9, engaged, is fed towards the rotating work. On reaching the required length of thread, the feed of sleeve 1 ceases and the tap is drawn into the work until the dogs are disengaged, thus allowing member 3 to rotate with the work, and the peg 20 to ride over cam 19. The rotation of the work is reversed, and the lathe turret and sleeve 1 are retracted, thus engaging peg 20 with the projection S on cam 19, to stop rotation of member 3 and the tool, and allow unscrewing of the tool from the work. It is stated that the tool can be rotated instead of the work. Chucks.-A tap 12 is secured in an adaptor 13, which is interchangeably mounted in a socket 10, and secured by a transverse pin 21, which may be split as in Fig. 3, for tight engagement.
