Title: Improvements in coin freed apparatus
IPC: G07F11/24
Filed: 1922-12-18
Abstract: 212,972. Seligson, J. Dec. 18, 1922. Sale apparatus; coin action, mechanical-connection.-In apparatus for delivering a measured quantity of an article, the spindle 1 carrying the delivery drum is locked by a spring-controlled pivoted detent 8, Fig. 1, which is of the first order of levers and has a locking member 11 freely mounted on a pin 12 and adapted to engage in notches 21, Fig. 3 in the boss 15 of a plate 14 fixed to the spindle. The detent is pivoted at 9 on a front plate 5 and is released by a coin inserted in a slot 6 being moved into a tangential groove 7 leading to the money-box by pins 19 on the plate 14, the coin in its passage forcing down the tail 26 of the detent 8. The length of the notches 21, in conjunction with the free mounting of the member 11, permits some lost motion between the spindle 1 and the detent. An arm 22 having a notched tail 28 and controlled by a spring 23 is pivoted to the front plate 5 in the path of the pins 19. The arm 22 forms a means for positioning the pins 19 in the assembly of the apparatus. Coin-slit closing-devices.-The coin-slit is closed by a plate 33 controlled by a spring 34 and moved into closing position by cam surfaces 31 on the plate 14 engaging a tail 32 on the plate.

Title: Improvements in attachments for tractors
IPC: B62D49/08
Filed: 1922-12-18
Abstract: 212,333. Greasley, H. M. Dec. 18, 1922. Stop gear operated by tilting of vehicle.-The clutch is disconnected automatically when a tractor rears due to excessive tension in the drawbar. A member 11 pivotally mounted on the rear axle of the tractor is retained by a weight 14 in a given position such that it is unaffected by tilting or rearing of the tractor. When the tractor rears. its movement relative to the member 11 disconnects the clutch and prevents further rearing movement. A pin or roller 22 on an arm 12 carried by the member 11 works in a slot in a pawl 21 adapted to engage a ratchet wheel 10 which rotates with the axle driving member; the pawl, when so engaged, rotates the two armed lever 16, 17 about its pivot so that the pull rod 24 acts on the clutch operating lever L and disengages the clutch. The slot in the pawl 21 includes a circumferential part 20 and a part 20<1> with a radial component so that the pawl is normally held clear of the ratchet wheel but is free to engage therewith when the pin 22 engages the part 20'. A spring tends to force the pawl into engagement. The clutch lever L is operated in the ordinary way by a pedal, a slot 27 being provided for the connection to the pull rod 24 so that the emergency stop gear is not affected.

Filed: 1971-10-13
Abstract: 1363647 Bale-loading apparatus A C BUCHANAN and W G THOMSON 13 Oct 1971 [16 July 1970] 34553/70 Headings B8H and B8E Apparatus for loading bales of hay from the ground and depositing them on to a trailer 2 comprises a boom 1 having a base 6 pivotally mounted by a shaft Y on the trailer, a bale grab 3 being carried by the boom at its outer end and consisting of fixed arms 13, 14 and a movable jaw 15, a ram 27 being pivotally connected at 25 to one end of a lever 22 pivotally mounted on the base 6 by means of a shaft 24 its other end being pivotally connected at 23 to a rod 18 which is connected to a link 19 connected to the jaw 15. In operation the boom initially extends downwardly and laterally of the trailer 2, the ram 27 is actuated and thus moves an element 28 located on the end of the lever 22 into engagement with a tongue 29 on the base 6, the lever 22 thus pivoting anticlockwise and, through the resulting movement of rod 18 and link 19, causes the jaw 15 to move to the left in Fig. 2 to grab a bale 31. Further movement of the piston-rod 26 causes the boom 1 and bale grab 3 to swing upwards, and when the piston-rod 26 is fully extended the boom 1 is in a vertical position with the bale grab 3 in position over the trailer 2. Due to the momentum and/or the overhanging weight of the bale 31 the boom 1 continues to swing inwards causing the shaft 24 to move upwardly and thus the lever 22 to pivot clockwise about the point 25 due to the fact that the lever 22 is connected to the pistonrod 26 which is at maximum extension, the rod 18 being thus caused to move to open the jaw 15 and thus release the bale 31 which drops on to the trailer 2.

Title: Device for measuring the cooling time of welds
IPC: G01J5/00
Filed: 1974-08-12
Abstract: 1441876 Thermocouple mountings CENTRE DE RECHERCHES METALLURGIQUESCENTRUM VOOR RESEARCH IN DE METALLURGIE 12 Aug 1974 [10 Aug 1973] 35383/74 Heading H1K [Also in Division G1] The cooling time of a weld is measured by means of apparatus comprising a pistol carrying a photo-cell monitoring the temperature of the weld and at a predetermined temperature causing injection of a thermocouple into the fused metal of the weld, whereupon a timer is started and stopped under the control of the thermocouple. Pistol construction, Figs. 3, 4.-The pistol comprises two parts. The trigger part carries the photo-cell 8 which on sensing the operational temperature as set by potentiometer 11 actuates an electromagnet 9, which causes trigger 13 to pivot about 27 freeing sear 25 from the pawl 26. The sear is mounted on barrel portion which seats into parts 23a, 14a. Spring 7 is now released to cause the thermocouple 2 to be forced forward, a pneumatic piston deadening the recoil of the pistol. The pistol may be mounted adjacent a deposited metal weld 4 to be measured, by means of a magnetic holder 15 which is attracts a steel part of the pistol butt, and prop 20. Aluminium may be used for lightness of construction and brass for protection against splashing. The trigger may be actuated manually. Circuits.-The photo-cell is infra-red sensitive and its output is amplified and indicated on a meter (30), Fig. 5 (not shown). A first comparator is set with a reference level which is a much higher temperature than that at which the control action is to be performed. This is to ensure that the temperature is falling before a second comparator, set with a reference level at the temperature at which control is to be performed, can operate the relay (19). The circuit for the thermocouple (a rhenium-tungsten device) has a similar safeguide comparator to ensure that measurement only takes place when the temperature is decreasing. Two further comparators control the starting and stopping of a timer between the temperatures 800 and 500 C.
