, UNITE STATES PATENT OFFICE.

' GEORGE H. NYE, or CHICAGO, ILLINoIs, AssIeNoE TO THE NYE STEAM vAoUUM PUMP coMPANY, OF ILLINoIs.

' STEA.M VACUUM-PUMP.

SPECIFICATION forming part of Letters Patent No.360,'781, dated April 5. 1887,

Application filed August 9.3, 1886.

To all whom it may concern:

Be it known that I, GEORGE H. NYE, a citizen of the United States, and a resident of Chicago, county vof Cook, and State of Illinois, have invented new and useful Improvements in Steam Vacuum-Pumps, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which Figure I is a plan View of the upper side of the lower head to one ofthe cylinders of a steam vacuum-pump patented to me on September 5, 1882, No. 263,803. FigII is a vertical section through Fig. I on line as. Fig. III is a vertical section on line z, Fig. I. f

Thepurposeof this invention is to soimprove' the pump patented to me, as aforesaid, as to make it more efficient in elevating gravel and solid material from the bed of the stream.

The pump as formerly constructed and 0p erated by me served a good purpose for elevating sand with water; but itwas defective in that,when a bed of gravel and small stone was reached, .this coarser material would interfere with the working of the valves, and therefore render the pump inoperative for this purpose. Careful experiments, made for the purpose of perfecting this pump for elevating theordinary coarse material composing the bed of astream,has demonstrated that the passage-way through the base of the pump to the inside of the cylinder should be formed on such curves that no dbris will lodge therein, and that the valve, when elevated, shall be free to move to any point within its seat that it may not check the upward movement of the solid matter entering the cylinder. I have embodied these improvements in my said pump,

- as follows:

A represents the top surface of the lower .head toone of the cylinders of my aforesaid ther, serve the purpose of bringing the seats Serial No. 211,694. (No model.)

of the valves so far above the lower heads of the cylinders as to bring the gravel and coarse material below the seat of the valve at each time the cylinder is charged.

one-fourth the height of the cylinders, or'the valves would become choked with solid material elevated. The conical valves employed are shown at J K, and to hold them in place they are connected by chains I, whose lower ends are fastened'to the bottoms of pipes E,

the chains being long enough to allow the valves to have the movement shown at Fig. II.

Toprevent the valves from jerking suddenly the chains when struck by solid matter, as indicated by dotted lines w, Fig. I, the chains are attached to pistons H, which pass through seats formed in the bottoms of pipes E, and have placed on their lower ends coilsprings F, or other suitable springs, and col lars G, whereby the chains may somewhat yield and relieve the valves from sudden shocks, as they would be subject to, if the chains had non-yielding attachments. The pump with these attachments will be operated the same aswith the old valves, the superior results, however, being as stated, as shown by the working ofthe pump with these improvements in various places in this country. One

of the valves at N is broken away to show that the valves are preferably made hollow.

It will be understood that each pump has two vacuum-cylinders and one valve, K J, to each cylinder.

I claim as new and desire to secure by Letters Patent- 1. As an improvement in steam vacuum pumps, the lower cylinder-heads, combined with the upwardly-projecting cylinder, valveseats B B, the conical valvesJ K, chains I, and inlet-pipes E, as specified.

2. The combination of the lower cylinderheads, A, with the upwardly-projecting cylinder-seats B, valves J K, chains I, pipe, and piston H, which is provided below the pipes E with the spring F, as specified.

. GEORGE H. NYE.
