VALVE.

Specification of Letters Patent.

'.t'atentecl April 23, 1907.

Application filed December 8,1905. Serial No. 290,890.

Be it known that I, CLEMnNs liEssEl.- BACH, a citizen of Germany, residing at Rath, near Dusseldorf, Germany, have invented 5 new and useful improvements in Valves, of

which the following is a specification.

In valves of the kind used in pumps, blasts and the like the spiral springs heretofore employed yield to the weight of the valve-body 1o causing the latter to deposit with its full weight in the inner and outer valve passages and producing thereby a unilateral friction resulting in an early wear-out of both the valve and its seat. Moreover the unilateral I 5 friction causes an irregular opening of the valve and 'thereby a hammering and :fluttering and when the valve closes the said friction causes a one-sided closure.

My invention relates to an automatic valve of the kind referred to where the disadvantages alluded to are avoided. The valvebody moves horizontally or inclined and is charged with a spiral spring capable of carrying the weight of the valve-body preventing thereby the latter from depositing in the passage and avoiding a friction pressure of the valve therein.

In describing my said invention l refer to the accompanying drawing, in which Figure l is a section through a valve embodying myv invention; Fig. 2 a section through part of a valve, showing a modifica.- tion; Fig. 3 a similar section tln'ough a further modification; Figs. el and 5 ai'e details of the spring; Figs. (i and 7 are corresponding views of a modification of the spring, and Fig. S is a section tln'ough a further modilication of the valve.

The main feature of my invention consists of mounting the spiral spring f in such way that its axis is inclined to the direction in which the valve moves thereby relieving' the passage of the valve. As shown by Figs. l, 4, this can be done by ceiling' the spring about an eccentric core or by mounting the spring-seat L inclined as shown in Fig. 2, or the face l) where the spring touches the valve may be peripherally inclined as illustrated in Fig. 3.

Willen the valve is in its ordinary position it charges with the weight of its body the spring, the latter assuming the position shown in Figs. i, 5, 6, 7. The axis coinciding with the line of the direction in which the Valve-shell moves, where the valve and .reduction of the pressure exerted against it spring touch each other, the action of the spring becomes equal throughout notwithstanding the valve-shell is carried by the sprin The spiral spring' may be coiled cylindric- 6o ally or it may be conical or of any other shape and there may as well be provided a plurality of springs for one valve each mount ed as described. The said spring f may be supported by an elastic metal plate or elastic straps as shown in Fig. 8 where the seat of the springfis formed of such an elastic plate y) provided with a rim c. then the valve 0 is suddenly raised during the movement of the piston the spring fis thereby compressed such pressure actuating at the same time suddenly and with increased force upon the elastic plate which is thereby made to recede and while so receding the valve-shell deposits on the rim c which it does through the counter-action of the spring quietly and equally without requiring any other' elastic means.

lhe pressure of the elastic seat of the spring causing an early closing movement of the valve at once with the reduction of the counter-pressure the valve cone deposits quietly during the downward movement of the spring while in the constructions heretofore in use the said valvecone was on the raised and torn from its'seat much later and then vehemently, the result being the hammering above alluded to. The employment of the elastic seat plate or other elastic support for the spiral spring f removes at the same time the fluttering of the valve-cone which had heretofore often occurred when the spring j" had been provided stronger in the endeavor to avoid the aforesaid hammering. rl`he said elastic support for the spring may be provided in anysuitablc place in the valvechest and be made of any material suitable for the purpose.

that I claim as my invention and desire to protect by Letters Patent is:

l. In an automatic valve of the kind used in pumps and blasts the combination of the valve-mechanisni as ordinarily used with a spiral spring the axis of which is inclined to the line in which the valve-body moves, substantially as described.

2. In an automatic valve of the kind used in pumps and blasts the combination of the ordinary valve mechanism with a spiral spring suitable to support the vweight of the 11o IOO valve-body, the aXis ofthe said spiral spring moves, and an elastic support for the said 1o being eXcentrc to the line of movement oi' spiral spring, substantially as described. the valve, substantially as described. i Signed by me at Dsseldorf, Germany7 this 3.
