Abstract: 759,653. Lubricating. SATZGER, E. July 26, 1954 [July 29, 1953], No. 21759/54. Class 12 (3). A device for distributing media, more particularly lubricants to a plurality of outlets by pistons operated successively by the pressure of the lubricant comprises four pistons 1, 2, 3, 4 coupled together by means of rollers 6 each of which is provided at the end with an eccentric pin 8 engaging in a bore 7 in a piston. Each piston has a control recess 13 adapted to be put in communication with an outlet 15. The pistons are mounted in cylinders in a casing 5 which is provided with an inlet 9 for lubricant and with conduits 10, 12 for conveying lubricant to the cylinders. When the piston 1 is in its lowest position, as shown, the adjacent piston 2 is positioned so that there is substantially no gap between the upper edge of the control recess 13 and the outlet 15 whereas there is a gap or spacing a between the lower edge of the control recess 13 and the upper edge of the inlet conduit 12. This ensures that there is no direct flow of lubricant from the inlet to the outlet. The lubricant is fed to the top of the pistons by way of conduit 10 and to the control recesses 13 by way of conduits 12, and is discharged from below the pistons by way of conduits 14 leading to the outlets 15. A similar arrangement for preventing direct flow from inlet to outlet is provided in a device otherwise constructed as described in Specification 759,638.

The top of the crescent-section space 6 around the tube 4 is connected by tubes 9, 10 to a hollow dipstick extending into the engine sump or other container for the liquid whose level is to be measured. To obtain a level reading the bulb 12 is squeezed to displace the measuring liquid through the hole 13 and around a baffle 16 into the body I wherein it rises in the space 6 and tube 4 to a degree depending on the depth of the liquid to be measured, the level then being read by comparing the level of the liquid in the tube 4 with graduations formed thereon.

A device for selectively removing cigarettes from a stream thereof delivered continuously in axial alignment from a continuous rod cigarette making machine comprises a pusher 2 which reciprocates to deflect the cigarettes transversely of their axes on to a conveyer moving at right angles to that of the main stream and is characterized in that the pusher mechanism is mounted on a base plate 1, slidable in guides 3, so that it may be withdrawn to a position in which it no longer deflects cigarettes. The pusher 2 is reciprocated by rotary movement derived from bevel gears 9 and 11 and shaft 12, the whole of which mechanism may be moved to the right as viewed in Fig. 1 by operation of a piston 5 of a cylinder 4. The piston 5 is connected to one arm of a two-armed lever 6 pivoted at 7, the other arm being connected to the base plate 1. Operation of the cylinder 4 may be controlled manually or automatically in dependence upon e.g. the quality of the cigarettes or the change over from one reel of wrapper to a new reel.

Crucibles h a v e their tap - holes plugged by material which does not contaminate the contained metal and is preferably a material which can be incorporated in the said metal. In an application to hot liquid steel produced by the alumino-thermic process, the plugging means comprises a pin 1, Fig. 1, closing the tap-hole 2 of the crucible, a disc 4, and a body 7 of subdivided particles, all of which are preferably of simliar metal to that in the crucible. The metal may be tapped by striking the pin 1 so as to unseat it, but by properly apportioning the material 7, the crucible will automatically tap itself at a given time by the melting of the said material 7, under which conditions the pin 1 may be dispensed with. The disc 4 may be dispensed with if the head of the pin 1 is of sufficient size to close the tap-hole. In a further modification, a pin 9, Fig. 2 is employed alone and is of the same material as that within the crucible. The pin 9 may be adapted to be completely melted by the molten metal, or may be unseated, as described above.
