Title: Improvements in or relating to coin-freed lock mechanisms
IPC: G07F17/14
Filed: 1944-11-01
Abstract: 587,371. Coin-freed locks. TITE, R. G. Nov. 1, 1944, No. 21330. [Class 27] A coin-freed lock for a safe in which property may be left temporarily, and operable by a key which can be removed whilst the safe is in use, is normally locked against turning movement by the key by the engagement of a stop on a wheel with a resilient locking catch. An inserted coin enters a pocket in the wheel and disengages the latch during an initial movement permitted by the resilience of the catch, whereupon the lock can be operated and the key removed. The invention is shown applied to a tumbler barrel type of lock. The wheel 10 with diametrically opposed coin pockets 11 is loosely mounted on the barrel 18 of the lock, and has a pair of pawls 16 by which it is driven (anti-clockwise) by a four-point ratchet wheel 17 secure to the barrel. A contraset ratchet 13 secured to the wheel, and engaged by pawls, prevents reverse rotation of the wheel. Normally, one of a pair of stops 12 on the wheel bears against a catch 19 to prevent the lock being turned by the key which is held in the lock by a sliding bolt (not shown). An inserted coin passes down a chute 21 and enters one of the pockets in the wheel. During initial turning of the key and wheel, permitted by a resilient plunger 19a controlling the catch 19, the coin engages a ramp 23 on a lever 20 carrying the catch, so freeing the wheel for the normal 90 degrees rotation of the lock, and enabling the safe door to be opened. In this position, Fig. 3, of the mechanism, the coin bears against a ramp 24a which lifts the key retaining bolt enabling the key to be withdrawn. After inserting the property in the safe the door is closed-to and can be reopened to recover the property by using the key only, the further actuation of the lock discharging the coin into a chute 26 and bringing the second stop 12 up against the locking catch 19, the mechanism then being in its normal position for actuation by a further coin. A pawl 29 engages a ratchet 28 on the lock barrel to prevent this further rotation being made inadvertently whilst the door is open: when the door is shut the lock keeper prevents full extension of the lock bolt and, in this position, the bolt actuates cam mechanism to disengage the pawl. Coin-slit closing-devices; indicators. - When the safe is occupied, the coin slot is closed by a slide 35 actuated by a sliding bar 34 and lever 33 engaged by a cam 14 secured to the coin-wheel. The bar 34 also actuates an "engaged" indicator 36.

In an arrangement for mounting a bulky implement, such as a combineharvester, on a tractor, the implement has a pair of laterally-spaced main mounting elements 30 (Fig. 7) for engagement with complementary elements 55 (Fig. 6) on one of the tractor rear half-axles, the implement being further provided with props 33, 34 to support it when detached from the tractor and with a jack 19 which is removable attachable to the front of the implement so that it can lift the implement about the rear props to enable the front prop 34 to be removed whereafter the jack lowers the implement to engage the front and rear elements on implement and tractor. The combine has a header 20 which is pivoted to the main body 21 by dismantlable brackets 22 so that the header is normally dismounted when the implement is to be lifted on to the tractor (Figs. 3 and 4). The jack is then moved from a bracket 18 to a bracket 17 and is attached to the header by a spring mounting. The header is thereafter adjustable about the pivots 22 by the jack. The main body 21 has three transverse tubes 25, 26, 27 the fore and aft of which receive spigots on the ends of the stands and the two rear ones of which may have extensions 74 (Fig. 7) to carry a bagging platform 70 (Figs. 1 and 7). The rear main mounting on the tractor (Fig. 6) comprises a pair of tubes 12, 47 secured together by bridge-plates 49 carried on a laterally-extended half-axle casing 48, the tube 12 having the elements 55 which are engaged by the channel-members 30 (Fig. 7) on the tube 26. The front mounting comprises a tube 61 carrying an upright beam 13 with a socket 14 at its upper end to receive the end 29 on a member 28 carried by the front tube 25 on the implement. A detachable clamp (not shown), secures the members 14, 29 together when engaged. To enable the tractor to be aligned with the implement before mounting, the stands are coupled together by beams 35, 36, the tractor being driven with its wheels in contact with the beam 35 (Fig. 1) to ensure correct lateral positioning. During tilting of the implement about the rear stand, a stay 41 (Figs. 3 and 7) is provided to prevent backward movement of the implement.

Abstract: 205,924. Payne, A. E. H. Aug. 8, 1922. Addition to 193,574. Cranks; crank linkages.-Comprises a modification of the crank mechanism set forth in the parent Specification, adapted to increase the arc of crank effectiveness in power or other drives. The crank arm D is pivoted at E within a recess or the like C formed in a main disc cr plate A carried by a shaft B rotatably mounted in bearings, the pivot E being eccentric to the shaft B. The arrangement is such that if, for example, the crank-pin F is connected through a link G to a driving member reciprocating between the limits H - - H<3>. the disc is directly rotated by engagement of the arm D with the forward wall of the recess C except at each end of the reciprocatory stroke, when the disc momentarily overtakes the arm D owing to the eccentric displacement of the pivot E. Thus at one end of the stroke the disc moves in advance of the crank arm between the positions F<2>, F<3>, the crank arm subsequently overtaking the disc between the positions F<3>, F<4>. To retain the arm D in the recess, the outer end thereof may be formed with an overhanging lug or lip engaging the back of the disc. Two such crank devices may be provided for use on a bicycle or a machine driven by foot power. Instead of the recess C a rooking space of any convenient form may be provided on the disc A.

Classes 98(1) and 98(2) In a stereoscopic camera having coupled shutters 1, 2, the setting of the diaphragm aperture and exposure time is effected by adjusting shutter 1 only, and an exposure computer is carried by the shutter 2. A rotatable ring 5 on shutter 2, Fig. 1, is turned to bring the appropriate number on a scale of film emulsion speeds opposite an index 6 on a fixed ring 7 which also carries a series of symbols representing different kinds of subjects to be photographed, and an arbitrary light value is read off a scale on ring 5 opposite the appropriate symbol. A pointer 8 connected to the exposure-time control of shutter 1 is disengagably connected to a rotatable ring 9 connected to its diaphragm aperture control, and is set to indicate the light value read off ring 5 on a scale on ring 9. The exposure time and diaphragm aperture controls of shutter 1 are then connected together so that by turning ring 9 any one of a number of equivalent combinations suitable for the subject chosen may be selected. At the same time the settings are transferred to the controls of shutter 2 by links 3, 4. In a modification, Fig. 2, the shutter 2 carries an index in the form of a wire ring 12 which is set to indicate the appropriate film emulsion speed on a scale on a fixed ring 11. A rotatable ring 10 carries a series of symbols representing weather conditions, and is rotated until the appropriate symbol is brought opposite that symbol in a series of symbols on ring 11 which is appropriate to the subject to be photographed. The light value required for setting the controls of shutter 1 is then read from a scale on ring 10 by the index 12.

Class 59 In a method for pretreating green fodder which is to be ensiled and which is mechanically bruised and disintegrated to such a degree that a large number of cells are opened, the moisture content of the material is reduced to between 72 per cent and 76 per cent by weight by extracting juice and/or by adding a dry substance during the pretreatment of the material. The dry substance may be added during or after the bruising &c. operation. The juice may be extracted during a squeezing operation which may be simultaneous with the bruising &c. operation and the juice thus extracted may either be mixed with a dry substance and ensiled separately or mixed with the bruised, disintegrated and squeezed material with the addition of dry substance in sufficient quantity to reduce the moisture content of the material to be ensiled to the desired value. The dry substance may be any material which is suitable for use as a cattle food. If desired, a small quantity of a substance containing a soluble and therefore rapidly fermentable, carbohydrates, e.g. molasses, may be added to the material to be ensiled, and such substance may be added before or during as well as after the mechanical treatment of the fodder. Apparatus for carrying out the method comprises a casing 1 provided with an inlet opening 2, a conveying screw 4, and one or two grids 5, 6 followed by a tapering discharge nozzle 3.
