H. LBNTZ. MULTIPLE SEAT VALVE.
APPLICATION FILED MAR. 31, 1905- WVENT R, Huso LENTZ,

Specification of Letters Patent.
Patented Oct. 31, 1905.
Application filed March 31, 1905- Serial No. 253,111.
To all whom it may concern:
Be it known that I, HUGO LENTZ, a subject of the German Emperor, residing at 10/11 Potsdamerstrasse, Berlin, Germany, have invented a new and useful Improvement in Multiple-Seat Valves; and I do hereby declare the following to be a full, clear, and exact description of the same.
This invention relates to multiple-seat valves and to a method of assembling the parts thereof.
In order to decrease the stroke of the piston or other part of a machine, multiple-seat valvesthose having a plurality or succession of valveshave been provided. Prior to my invention, so far as I am aware. it has been the ordinary practice to provide the valve-box with successive seats each of which has a larger diameter than the preceding seat and to fit therein a valve-body provided with a succession of valves each of which has a smaller diameter than the preceding valve. Another prior structure has employed a plurality of valve-seats all of substantially the same diameter. While such a structure has the advantage of well-nigh perfect equilibrium, yet the cost thereof has heretofore been prohibitory, due to the fact that the valve and the valve-box or a part of the latter are cast jointly, so as to assure a close and maintained fitting of the parts.
My present improvements are illustrated in the accompanying drawings, wherein- Figure l is a longitudinal section of onehalf of a valve embodying my invention, and Fig. 2 is a bottom view of such a valve.
The drawings show a succession of valves of like diameter and a corresponding succession of valve-seats of like diameter. This structure is preferred because of the more perfect equilibrium thus obtained.
Referring to the drawings, a represents a tubular valve-body having four successive annular valves all of the same diameter. Said valve-body is inclosed within a valve-box, which is divided axially of the valve or otherwise built up in sections, such as b and c, and provided with a plurality of valve-seats all of the same diameter. The usual ports lead from such valve-seats.
As shown, the assembled parts are held together satisfactorily by being fitted within a casing or other part of the machine, and additional or applied attaching means are not necessary.
The assembling of the parts may be carried out in any desired manner. I preferably employ, however, a new method devised by me and which consists in dividing the valve-box lengthwise, fitting the parts 6 and 0 together,
working the assembled parts of the box, and thereafter opening the box or removing one of its halves, then fitting the valve-body a into the box, and again assembling the parts of the box. The whole is then slipped into the casing of the machine and secured therein.
What I claim is In a multiple-seat valve, a valve-body having a succession of valves of like diameters, and a valve-box wherein said valve-body is incased, said valve-box being divided into sections axially of the valve and having a succession of valve-seats corresponding in number with the valves and all of like diameters.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
HUGO LENTZ.
