SAME PLACE.
STUFFlNG-B OX FOR AIR OR G AS PUMPS.
SPECIFICATION forming part of Letters Patent No. 363.1156, dated May 24. 1887 Application filed October 13, 1886. Serial No. 216,109. (No model.)
To aZZ whom it may concern.-
Be it known that I, HENRY B. FORD, of the city, county, and State of New York, have invented a new and useful Improvement in Stufling-Boxes for Air or Gas Pumps, of which the following is a specification.
My invention relates .to a new form of stuffing-box, especially designed for air or gas pumps.-
My invention consists in the construction and arrangement of the box, hereinafter set forth, whereby any escape of gas from or entrance of air into the pump-cylinder is effectively prevented.
In the accompanying drawings, Figure 1 is a vertical transverse section of my improved stuffing-box. Fig. 2 is a horizontal transverse section on the line as x of Fig. 1.
Similar letters of reference indicate like parts.
A is the pump-piston. head, the remainder of the cylinder not being shown. Ois the pump piston-rod.
In the cylinder-head B is formed a cavity or recess, D. On the piston is a projection, E, adapted to enter said cavity. The pump cylinder is intended to stand vertically, as indicated in the drawings, the stuffing-box, hereinafter described, being located upon the lower cylinder-head. Projecting from said cylinder-head is an annular casing, F, which is open below, and which encircles the piston -rod The space adjacent to the cylinder-head and surrounding the piston-rod is packed, as indicated at G, with any suitable packing material. Surrounding the casing F is the body H of the box, which may tightly fit upon said casing, or be formed or otherwise secured thereon in any suitable way. The upper portion, I, of said box is enlarged, and is of greater diameter than the lower portion, J.
Entering the casing F is a packing-ring, K, which bears upon the packing G. Entering the smaller portion, J, of the box H is a similar packing-ring, L. The rings K and L are connected by rods M, which enter the annular space between the casing F and rod 0. Below piece or be secured together.
B is the cylinder-- in the part J, or be connected to said part in any other well-known way. 7 Passing through the part I of box H and into the annular space inside the casing F are two tubes, P and Q. Said tubes are provided exteriorly with suitable covers. In the upper part, I, of box His also arranged a valve, R, of any ordinary construction, and adapted to open inward when the exterior air-pressure is greater than that existing within the box. The parts, as above described, are assembled in the following manner: The casing F and box H may, as already stated, be made inone The packing G is placed within the casing F, and the packing-rings K and L are put in place upon the piston-rod. The packing N is then put in the box H, and finally the cover Ois tightlydriven or serewed'in, so as firmly to compress the packings around the rod. The tubes Pand Q then being opened, the whole interior space of the box is filled with (preferably) oil, and the tube-covers are replaced.
This stuffing-box operates to keep air out of the pump in the following manner. It is of course manifest that air can enter only when mosphere would force itself between pump rod and packing, and so enter the cylinder; but in the present case this is impossible. Any air which might tend to enter around the rod through the cover 0 and packing N is met by the column of oil. Furthermore, the air will not come in from below, because when the oilpressure is diminished the valve B opens i11- ward. Hence the worst result of the vacuum in the pump-cylinder is to cause a little oil to be drawn into the pump-cylinder; but this is scarcely possible, because the same pressure which tends to force the oil into the cylinder causes it to act upon the ring K, to cause the latter to press the harder upon the packing G. If, however, any oil should enter the cylinder, it will accumulate in the recess D, and out of this recess it will be squeezed and forced back into the box by the entry into said recess of to prevent escape of gas as follows: Any gas which might get out of the cylinder would first have to pass between the rod 0 and packing G. It could get no farther, because it would meet the oil. Pressure upon the oil would simply force the valve R the more tightly, and shut and crowd the ring L down upon the packing N,so that the oil would bar the further escape of gas, and be itself prevented from being forced out by the tight packingN and the closed valve R.
I claim 1. In a stnffing-box for air or gas pumps,
the box H, containing a liquid such as oil,
inner casing, F, packing-rings K and L, packthe oil into said box H, substantially as described.
HENRY B. FORD.
