Title: Improvements in couplings for trailer vehicles
IPC: B62D53/06
Filed: 1926-10-20
Abstract: 273,132. Imfeld, K. Oct. 20, 1926. Couplings for road vehicles.-A spring. coupling is so devised that excessive pull tends to raise the front of the trailer and transfer the weight to the rear axle of the tractor. In one form, Fig. 4, a draft bar B attached to the trailer is connected to a block A. The pull on the bar causes the block to move along an inclined slot D on the tractor against the action of a spring C. The bar B therefore rises and transfers some of the weight of the trailer to the tractor. The same result is obtained if the bar is connected to a hinged link A<1>,Fig. 5, and spring C. In another form the bar B is geared to nuts on threaded vertical spindles. The pull on the bar tends to raise the nuts against the. action of springs.

Void [Abridged as open to inspection under Sect. 91 of the Acts, March 16, 1935]. [Class 7 (iii)] A gasefier carburetter in which liquid fuel is heated and converted into fixed gases and " colloidalized vapours " comprises combustion and cracking chambers connected by a tube and means for supplying liquid fuel to the tube and combustion chamber respectively, the combustion chamber being provided with air inlets leading to a channel and the cracking chamber being connected to a source of suction. Twin float chambers 95, Fig. 2, supply one or more fuels to a body 15 containing combustion and cracking chambers from the latter of which the products pass to a stack 59, Fig. 3, having at its lower and upper ends respectively an air inlet 69 and a flange 60 for connection to an induction manifold. The float chambers may be secured to the opposite side of the body 15 if desired and the stack 59 be inverted relatively thereto to adapt the carburotter for use with a downdraught intake manifold. Light and heavy fuels are fod through opposite ends of a ridge member 111 on the cover 96 of the float chambers and pass respectively to the adjacent float chamber. Alternatively, either supply may be disconnectod and the other fuel be fed to both float chambers on opening a valve disposed centrally on the ridge 111. Light fuel from one float chamber flows past a metering valve 126 to an orifice opposite a fuel passage 53 leading to an annular channel 18 formed in a partition 16 dividing the body 15 into upper and lower portions. A tube 17 connects these portions and supports at its upper end a collar 19 having an outer flange 21 almost covering the annular channel 18 and an inner flange 20 resting on the tube and itself supporting a Venturi member 23 formed of metal having a higher coefficient of expansion than that of the tube 17. Clamped to the top of the body 15 by a cover 33 and rotatable relatively thereto is a combustion chamber 32 provided with air inlets 40 and a sparking plug 37 using as one electrode a hood 43 secured to a web 41 in the upper part of the combustion chamber. Baffles 42, 46 and a series of gauze screens 48, the inner one of which is corrugated, disposed over the air inlets 40, prevent damage from backfiring and the screens act as air filters. A charge fired in the chamber 32 sweeps across a sheet of heavy fuel, supplied from the second float chamber to a nozzle 54a in the tube 17, to vaporize and " crack " it in a bowl 24 secured to the lower portion of the body 15 by a bail 28. The treated fuel emerges through a passage 58a, Fig. 3, to the stack 59 where it expands and is mixed with air drawn in througn a valve 74 which may be held closed by movement of a bent arm to facilitate starting. At the upper end of the stack, idling ports 65 in a throttle 63 are closed and thereby cleared, by fixed pins 66 when the throttle is wide open.

[Classes 27 and 106 (v)] In the coin-freed liquid measuring and dispensing device described in Specification 382,793 and comprising a ported sleeve 9, Fig. 1, with attached measuring chamber 18 rotatable about a ported plug 10 which is secured to a liquid container by a coupling nut 11, the plug 10 is provided with a vertical duct C instead of the external groove described in the prior Specification to form an air lock relief during discharge of liquid from the chamber 18, this duct being connected to the top of the supply container by a pipe and also being connected directly to the atmosphere by an aperture 27. The duct A forms a passage for the liquid from the container to the chamber 18 and the duct 13 an air relief between the container and chamber during the filling operation. A spring-pressed finger-controlled air release valve 24, 25 is located in the flange 8 forming the top of the chamber 18. This valve is for clearing liquid from the lower ends of the air ducts when the device is used for dispensing thick liquids such as oils. Coin action, mechanical-connection ; fraud, preventing.-The sleeve 9 is rotated by a handle 15, a coin inserted through a slot 17 forming a driving connection between the inner forked end of the handle and the flange 8 which is mounted between top and bottom plates 1, 2, Figs. 1, 10, 12. The inner end of the handle has projections travelling in arcuate grooves 28, 29 respectively in the plates 1, 2 and the plate 1 has a downwardly depending flange 14 to accommodate which the handle is recessed. If the coin is too small it drops through a hole 39 in the plate 2 to a return shoot 7. The coin is carried along by the handle until it drops through a hole 35 to a coin-box 6. Just before reaching the aperture 35 the coin drops into a shallow recess 34 against the shoulders 36 of which the coin jams if an attempt is made to return the handle 15 and sleeve 9 to their initial position before the coin is discharged. The recess 34 is continued as an arcuate recess 38 to the coin insertion point, the recess 38 being narrower than the diameter of a proper coin so that coins of small diameter fall into the recess 38 and do not actuate the mechanism. To prevent badly worn coins from jamming against the edge of the hole 39 two pins 40, 41 are provided. The top plate 1 has an arcuate slot 42 in which the valve 24, 25 travels. If a coin is inserted before the handle 15 and flange 8 are brought back to their initial position, this coin is received in another recess in the flange and carried round to a return opening 49. The flange 8 is also provided with a snug or plate travelling in a groove 47 in the top plate to prevent fraudulent actuation by the insertion of thin strips of metal.
