Title: Improvements in or relating to devices for fastening vehicle wheels
IPC: B60B3/18
Filed: 1929-03-06
Abstract: 330,303. Zerbone, R. March 6, 1929. Detaching from, and attaching to, permanent hubs.-In a device for connecting a detachable wheel to a fixed hub of the kind in which a rotatable ring forming part of the detachable hub engages, by a bayonetcatch type of connection with grooved bolts secured to the fixed hub, the ring comprises a bush 25 formed with a flange 27 and a rim 31. The bush is mounted within the detachable hub 1, the latter being bolted at 3 to a ring member 5. The bush is screw-threaded at 29 to engage screw threads 23 on the ring 5. The bolts 11 are secured to the fixed hub, for example to the brake drum 14, and have recesses 41 adapted to engage with the flange 27 of the bush. They project through holes 7 in the ring 5, and the flange 27 is formed with recesses 39, Fig. 4, spaced similarly to the holes 7. The ring 5 is further formed with holes 9, in which are loosely mounted push pins 15 formed with recesses 43, camheads 19, and extensions 47. The rim 31 of the bush is formed with recesses 17 corresponding in position to the pins 15, and at these points cams 33 are fixed to the bush behind the recesses. When the wheel is in position, the solid parts of the flange 27 are in engagement with the recesses of the bolts 11, and the pins 15 are in the position shown in Fig. 1. To detach the wheel, the bush 25 is rotated, for example by means of a cap 35 screwed to its rear end, until the recesses 39 in the flange 27 coincide with the bolts 11, allowing withdrawal of the wheel. At the same time, the cams 33 engage the cam heads 19 and force the pins outwardly. This causes the heads 19 to enter the recesses 17 in the rim 31 to lock the bush 25 and ring 5 together, and the extensions 47 press against the brake drum 14 and help to force the wheel off. In replacing the wheel, the bush is rotated to locking position by springs 37, as soon as the heads 19 are disengaged from the recesses 17. This rotation, and consequent axial movement, of the bush drives the flange 27 tightly into the recesses of the bolts.

A weight 11 is slidable on the bar 2 and movable against the action of a spring 12. In operation, in order to insert a nut into a bore in a member, such as a tube, the nut is first screwed on to the element 4 and the latter pivoted to the position shown in Fig. 1, an eccentric bore in the sleeve, under the action of a spring 6 being provided to retain the nut in the pivoted position. The setting head, together with the nut, is then inserted into the bore as shown -in Fig. 2, and by rotating the sleeve 5, the nut is pivoted back to the horizontal position so that by lifting rod 3 via the bar 2 and handle 1, the nut is pulled into the bore. In order to secure the nut firmly in the hole, the weight is depressed against the action of the spring 12 and then rotated so that its upper surface abuts a pin 15. The weight is then rotated so that the pin is aligned with a bore 16 thereby allowing the weight to be urged upwardly by the compressed spring and so strike the handle 1. To extract a nut from the bore, the sleeve 5 is replaced by a sleeve 17, Fig. 7, which is adapted, after the element 7 has been screwed into the nut, to be moved downwardly so that a tapered end thereon contacts the collar 9 of the nut. By striking the handle the tapered end dislodges the nut from the bore and tips it into a vertical position so that it can be removed from the bore.

Title: Improvements in or relating to absorption refrigerating machines
IPC: F25B17/00
Filed: 1928-03-14
Abstract: 317,336. Vßg¾, P. V., and Magyar, V. March 14, 1928. Refrigerating, absorption machines for. -In a machine without pumps, an accumulator tank 13 arranged between the absorber 7 and the generator 1 is sup plied with strong liquor through a float valve 14 when the pressure in the absorber is temporarily equalized with that of the generator by the emptying of the pipe 8 conveying weak liquor to the absorber. The tank 13 is maintained at the pressure of the generator by a connecting pipe 15. The liquor may flow unobstructed from the tank 13 into the generator, but preferably a second valve 19 closes the outflow of the tank when the valve 14 is open. A further float valve 24 may regulate the flow into the generator when the valve 14 is closed and the valve 19 opened during a working period. The generated vapour, e.g. ammonia, passes through a pipe 4 to the condenser 5, and the liquefied refrigerant passes through a restriction 11 to the evaporator 6. The weak liquor is driven through the riser pipe 8 and through a nozzle 9 into the absorber, which is cooled by a water packet 10. When the tank 13 fills with strong solution, the float 16 closes the valve 14 and opens the valve 19. The float 23 in the generator is preferably funnel shaped and has a depending pipe 25 to direct strong liquor to the bottom of the generator. The cool strong liquor may exchange heat in a device 20 in the generator with the outflowing gas, which is thereby deprived of solution vapour, and a branch pipe 22 may be provided between the bottom of the generator and a liquid trap 26 in the vapour expulsion pipe 4, to facilitate liquid circulation at starting. The pipe 8 may open into an annular space formed by a weir 27 in the generator, and may pass through the interchanger 20 and through the water jacket of the absorber. The float 16 may be located in a depending sealing wall 17 in the tank 13, so as to close the valve 14 quickly, and a heat-insulated annular float 18 may be provided in the tank 13 to prevent condensation of vapour on the liquor when starting.
