PAUL CLERC, OF PARIS, FRANCE.
AIR-PUMP.
SPECIFICATION forming part of Letters Patent No. 341,453, dated May 11, 1886.
Application filed January $28,1886. Serial No. 190.004.
To all whom it may concern.-
Be it known that I, PAUL CLERC, a citizen of the French Republic,and a resident of Paris, in the Department of Seine and French Republic, have invented certain new and useful Improvements in Air-Pumps, of which the following is a specification.
My invention relates to improvements of that class of air-pumps which rarefy or remove the air in or from any suitable receptacle, bulb, or other object by means of a traveling column of mercury; and the object ot' my improvements is to provide a more complete vacuum by means of a common pistoupump. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is an elevation of my improved mercury air-pump in combination with a common piston-pump, and Fig. 2 is an elevation ofthe same pump in another position.
Similar letters refer to similar parts through` out the several views.
A disk, L, is iiXed upon a plate or table, M, by means ofa bolt, O, in such a manner that it may be inclined to all directions, but without rotation. To the disk L is xed an annular pipe, A B,which is provided with a U- ,shaped knee or bent, U. At the one side of the knee U is attached to the ring A B, to- Ward its half A, a pipe, C. which is connected at R with the vessel V to be evacuated. At the other side of the knee U, toward the half B of the ring, is another pipe, D, which forms the connection between the air-chamber E and the interior of the tubular ring A B. The air-chamber E is provided with a cock, S, from which a hose, N, or other flexible pipe, is conducted to the piston-pump Z, instead of which any other suitable air-pumping device may be employed.
In order to evacuate the vessel V or any other object connected with the pipe C, I move the disk L by means of the handles H in such a manner that al1 points of its circumference are raised and lowered after each other in the direction indication by the arrows, viz.: I move the top ofthe handle H in atrue circle and always in the same direction, there by the mercury, which lls partly the pipeA B, begins to travel inside the interior of the pipe A B, and advances, when rising from the knee U, an air-column supplied from the pipe C and the vessel V, thus rarefying the air in the latter. When this air column arrives from theotherside at the knee U,it cannot pass therethrougl1,as the knee U is always filled with mercury, being in any position the deepest part of the annular pipe A B. Thus the air is forced by the following traveling mercury column into the pipe D and the air-chamber E, wherefrom it is evacuated by the pump Z.
Owing to the arrangement ofthe knee U the air contained in the pipeD and air-cham ber E never communicates with the contents of the pipe C, as the latter are always separated from the first by two mercury columns, the traveling one and the one filling the knee U. The motion of the annular pipe A B may also be effected mechanically by making use of the power which drives simultaneously thqe pump Z.
Having thus particularly described and ascertained the nature of my said invention,and in what manner the same is to be performed, I declare that what I claim is- In devices for evacuating or rarefying air, the combination of a pump, Z,of any suitable construction with the swinging annular pipe A B,containing a traveling mercury column, and provided with the'rnercurylilled knee or bent U, the pipes C and D, the air-chamber E, and the flexible pipe or hose N, substantially as and for the purpose specified.
In testimony that claim the foregoing as my invention I have signed my name,in pres ence of two witnesses, this 30th day of December, 1885.
PAUL CLERC.
