SU5718A1 - Mercury air pump - Google Patents

Description

FIG. Figures 1 and 2 of the schematic drawing show the proposed mercury air pump in different positions.

On the horizontal fixed axis O, two identical equal-arm levers / and // are suspended in different vertical planes, of which the lever / is fixed and the lever // has a vrash, movement in the direction of the arrow 180 ° (and back), i.e. . shakes At the ends of both levers, arc-curved glass tubes A, B, C and D of the same shape and capacity are attached. The tube A at the lower end of the fli is connected by a rubber hose Poison with a tube G at its right end Zi) the other end of the tube G is open at the top. In addition, the tube A with the tube H2 at its lower end a is connected to the tank D, from which it is desired to deflate the air. Tube A at the upper end of a and a glass tube e (diameter 1 mm) is connected to an open vessel E. Tube B at the lower end b is connected with rubber hose b to tube B at its right end, the other end of tube B is open at the bottom. The lower end of tube B is connected by glass tube 2 to reservoir D. The upper end of tube B is connected by glass tube Ж to vessel Ж, open at the top. BG tubes are filled with mercury. If we neglect the weight of the rubber tubes (also filled with mercury), then the lever will be in the equilibrium position.

When the lever moves // in the direction of the arrow, mercury from tube D will overflow into tube L, and from tube B into tube B. Within the swing limits (amplitude 180 °), the lever // will be in equilibrium (indifferent) position in all positions .

When turning the pump 180 °, i.e. to the position in which tube D will be in place of tube B, mercury from tube G will flow into tube A, forcing out there the air found there through tube e to the atmosphere. (According to Fig. 1, vessel E and part of tube e are also filled with mercury, with air displaced from tube A, through tube e through vessel E will be released as bubbles into the atmosphere). At this time, in the right half of the pump, mercury from tube B, at the beginning of pump rotation, will be poured into tube B, which will be filled with it, reaching the position of tube G. Tube B will be empty (Toricellian void). and there will be no return inflow of atmospheric air, since mercury in vessel J and in the tube will close the message of tube B with the atmosphere. When mercury is completely poured from tube B into tube B, a message will open through tube 62 of tube B with tank D, from which air will flow into tube B.

The pump can be pumped out; after a while, depending on its capacity and the tank capacity D, the air from the latter can be pumped out.

The height of glass tubes should be greater than the height of mercury at the highest atmospheric pressure.

The subject of the patent.

Mercury air pump, characterized by the fact that it consists of four arc-bent tubes A, B, C and D, of which tubes A and B are fixed fixedly on the lever I, which sits on the fixed axis O, and is equipped with ends of ai b mercury with locks EE and LJ, and at ends a and 6i tubes a and 62 connecting the cavities of tubes A and B with a thinning space, and flexible hoses a and bd connecting the cavities of tubes with ends 1 and Zi of tubes B v (G, reinforced on freely rotating on the axis O of the lever // and having other ends of the VIG open.
