IMPROVEMENT IN PUMP CYLINDERS AND VALVES.

Specification forming part of Letters Patent No. 183,806, dated October 31, 1876; application filed J one 6, 1876.

To all whom it may concern Be it known that 1, DAN W. KELLOGG, of Battle Creek, in the county of Calhoun and State of Michigan, have invented a new and Improved Pump, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a vertical central section of my improved pump on line 0 c, Fig. 3; Fig. 2, a vertical central section of a check-valve of similar construction; and Fig. 3, a horizontal section of the pump or valve on line a; 00, Fig. 1.

Similar letters of reference indicate corresponding parts.

The invention has reference to an improved construction of valves and pumps for steamengines, and especially locomotives, that may be readily taken to pieces to be cleaned and put together at a great saving of time, and without stopping the engine; and the invention consists of a pump or valve made of de tachable sections, connected by a single center bolt passing through center of valve-seats. The valves are guided along the stems of the valve-seats, and the faces of valve-seats and sections ground together to make true and square joints.

In the drawing, A represents the casing or cylinder of the pump or valve, which is made 01' sections that are separated by the valveseats 0, the meeting edges or faces of the sections and valve-seats being ground up to form perfectly true and tight joints. The sections forming the pump or valve-namely, the usual air-chamber, pump-chamber, and lower valvechamber-are connected by one single bolt, A, that passes through the center of the valveseats B, being tightly held by end washers and screw-nuts. This one connection admits of ready detaching and replacing of the lower valve-chamber, for cleaning without stopping the engine, which saves considerable time and delay, as compared to the present fastening with two or more bolts. The valves B and D slide on hollow stems a of the valveseat O and E, being stopped either by contact with the next valve-seat, or by the head of pump or valve casing, or by collar, or sleeve, or bolt.

The valve and valve-seats are preferably made of brass, the pump or valve sections being made of iron.

The stem of lower valve-seat E comes in contact with under side of upper valve-seatO, and is ground to bear intimately thereon, to prevent leakage of water around bolt. The stem of upper valve comes in contact with a collar, or sleeve, or bolt, or the head of valve, to prevent leakage. The valves slide readily along the stems, following the suction and force action of the plunger, drawing in the water through an entrance-pipe of the lower chamber, and forcing it out through a discharge-pipe of the air-chamber.

The connection of the parts of the pump and the working of the valves are very reliable, and especially adapted for portable and locomotive engines.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut-- specified.
