usual manner of making, modifying, and
using the same, reference beinghad to the accompanying drawings, which form a part of the same, in which* Figure l, is a front elevation. Fig. 2, is a plan of the base. Fig. 3, is a plan of the base showing valves. Fig. 4 is a section on line m, Fig. 2.
-My invention consists in the mode of constructing the valve chamber which contains all the valves and the air chamber in double acting pumps in one, and entirely independent of the cylinders, so that the valves shall be easily come at and repaired without disturbing the cylinders or pipes, they being capped by the air chamber whereby a cheap and efficient pump is produced, which will answer all the purposes of a force and lift- 'ing pump, for domestic use, and can be readily employed for a fire engine, &c.
The construction is as follows: The two cylinders (a, a,) plungers (b) &c., are somewhat like those in ordinary double cylinder /'pumps; they are placed at convenient distance apart, and are connected at the top with a brace (c) which, by being extended up above their tops serves for a fulcrum to the pump brake (el) the lower ends of the cylinders are connected with an oblong base (e), that all the valve seats and waterways are situated inthey being so arranged as to be all on the same level, and covered with a single piece of leather, out of which the valves are formed; this base (e) is covered with a cap (f) that serves the double purpose of confining all the valves, and forming an air chamber for the induction and eduction pipes. The base (e) is cup-formed, and has a partition (e) which divides it unequally into two. rlhis partition is U- shaped, as clearly shown in red lines in Fig. 2. There is a plate cast upon the top of this base, with openings through it, as represented in Fig. 2; at the end where the vinduction pipe (g) (see Fig. 4,) is situated there are two oblong poles (L', L,) i,merely to form a connection with the air chamber above; two sinallerhl's ig) 'also open on the same side of the partition e that serve as valve seats for the two induction valves z",) and outside of them are two other openings (la, 1.2,) that open into the waterways (Z, Z,) connecting with the cylinders;
and on the opposite side of the partition (e) to that where the holes it and z' are situ-y ated as clearly appears in Fig. 2, the space on this latter-named side of partition (e) is divided int-o three by two short partitions (6, e,), also shown in Fig. 2, by red lines; into the two outer spaces the last-narned openings Ic in the top plate communicate; there are, besides these openings, two others (m, m,) connecting with the same chambers and forming the seats of the delivery valves m; and between them there is a third, lettered (n), that communicates with the delivery pipe (o) a flat piece of leather (p) see Fig. 3, covers the whole surface of the plate, in which holesare cut over the opening at (h, la); at (lo, 73,) and at (n) it is also cut, so as to form valves over (i, z',) and (m, m,). The valves over (z', z',) are the foot valves,fand thoseover (m, m,) are delivery valves; those parts of the leather which are left between the openings and valves, as well asv all around the outside,
form a packing for the joint between the. base and the air chamber (g), this air chamr i are not required to be disturbed in renew'-` ing the valves or adjusting them, which simply requires the displacementof the cap or airchambers. Thecompartment (g) is yfor the purpose of relieving the suction pipe;
and the other (g) is for the delivery pipe. The operation `of the'pump is similar to that of the ordinary double cylinder pump. The water rises through the pipe (9,) enters the air chamber Q; thence under the partivalve thence through lo and Z) -into the pump cylinder from which it is forced on the descent of the piston through the foot `tionV (r) into the cap' through the valve (m) into the air chamber (gi') and above described and set forth; that is to 10 thence to the delivery pipe (0); the arrows say having the cap so constructed as to form denote its course in Figs. 3 and 4. the air chamber and conne the valves as Having thus fully described my improvespecified.
ments, What I .claim therein as my invention,y
and desire to secure by Letters Patent, is- H' PARMELEE' The combination and arrangement of the Witnesses:
valves, with the air chambers, substantially SIMON P. KAsE,
in the manner and for the purposes herein JAMES MARSHALL.
