HENRY CREAMER, OF NEW' YORK, N. Y.
STEAM-TRAP SPECIFICATION forming part of Letters P Application led June 27., 1888.
To all wiz/077@ it may concern:
Beit known that I, HENRY CREAMER, of the city of New York, county of New York, State of New York, have invented certain new and useful Improvements in Steam Traps and Feeders, of which the following is a specilication.
This invention relates to certain new and useful improvements in that class of machines known as steam-traps and feeders, and which serve for the purpose of conducting water of condensation from steam pipes, radiators, engines, &c., back into the boiler.
The object of my invention is to provide a new and improved steam-trap, which is simple in construction, effective in use, and not liable to get out of order.
The invention consists in the combination, with a steam-cylinder, of a water-cylinder in the same, closed at its lower end and open at its upper end, a piston formed on each end of the water-cylinder, a neck fitting closely in said inner or water cylinder, and suitable valves and mechanism for operating the same.
The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claims.
ln the accompanying drawings, Figure l is a vertical transverse sectional view of my improved steam-trap, showing the piston lowered. piston partially raised. Fig. 3 is a diagrammatic view showing the connections between the boiler and the steam-trap.
Similar letters of reference indicate corresponding parts.
The cylinder A, which is turned olf smooth on its inside, is provided with a bottom head, A', and a top head, Aseeured on the ends of the cylinder in the usual well-known manner. The water-cylinder C, having less diameter than the steam-cylinder A, is closed at its bottom and provided at its top and bottom with exterior annular pistons, C and C2, respectively, said pistons fitting closely within the steam-cylinder and being provided with grooves for receiving suitable packing. The top head,A, of the steam-cylinder is provided on its under side with a downwardlyprojecting neck, D, the lower end of which lits closely within the water-cylinder C, said Fig. 2 is a similar view showing` the AND FEEDER.

neck being provided at its lower end with eX.- terior annular grooves for receiving packing.
The neck D may be contracted for a part of its length between its upper and lower ends for the purpose of increasing the space between the inner surface of the upper part of the steam-cylinder A and the outer side of said neck. The top head, A', of the steamcylinder A is provided with an opening, B, of the same diameter as the top part of the neck D, and above said opening the bonnet E is held by suitable bolts on the upper surface of said top head. A shaft, F, journaled transversely in one part of the bonnet, has one end projecting beyond the bonnet, which end is provided with an arm, F to which one end of the check-rod G is pivoted. Within the bonnet an arm, Il, projects from the shaft F, and from the swinging end of said arm the float J is suspended within the enlarged upper end of the neck D.
On the upper surface of the top head, A', the valve-casing K is secured, in which the rocking valve L is mounted to turn, said valve being rigidly mounted on the transverse shaft H, provided at one end with the arm M carrying the weight M2. Adjacent to said arm M', or, if desired, on the opposite end of the shaft M and outside of the valve-casing, the sleeve N is loosely mounted on the shaft M, and is provided with a notch, N', the ends ot` which can engage a pin o1' stud, N 2, projecting from the shaft M. Said sleeve N is provided with an arm, O, connected by a rod, O',
with the outer end of an arm, P', on a transverse shaft, P, journaled in a projection, Q, of the steam-cylinder. lVithin said projection an arm, R, projects from the shaft P into the interior of the stealn-cylinder and into the space between the top and bottom pistons, C and C2, of the water-cylinder C.
The channel S, for the exhaust-steam, leads 1 from the valve-casing K to the top of the steam-cylinder, and another channel, T, leads from the valve-casing K through a suitable projection on the outside of the steam-cylini der to the bottom of said steam-cylinder. As shown in the drawings, it would seem that said channel T was closed by the projection 1 l l i i Q; but said channel is curved around said projection, or the channel is arranged at one The rocking valve L is side of the same.

provided in its rim with a recess, V, and the casing K is provided on its inside with a recess, L i
That end of the rod G opposite the one connected with the arm F' is guided by a suitable lug, G3, on the valve-casing K. The channel a leads, within the top head A', `from the channel S to the opening B in said top head, and the end of the channel a is closed by a' screw-plug, b, which can also be screwed into the lower end of the channel S. The projection Q on the side of the 'steam-cylinder is provided with an opening with which a' pipe, cl, is connected, which pipe is also connected with the pipe o or m. The valve-casing K has a neck, g, for receiving the pipe 7i, that conveys live steam to the valve. The pipe o serves to conduct the water of condensation into and outof the trap, and is connected with a pipe, m, that conveys the water from the returnpipe and with a pipe, r, leading to the boiler. The pipe m is provided with a check-valve, m', and pipe r with a check-valve, i", both opening in the same direction.
The operation is as follows: As shown in Fig. l, the trap is empty and the water-cylin- Ader and its pistons are lowered. The live steam is shut off and .the water from the returns passes through the pipes m and o into the bonnet E, iows over the iioat J, through the neck D into the water-cylinder C, in which it accumulates and rises. When said watercylinder is filled, the water rises in the neck D and finally raises the oat J, whereby the arm H is swung upward. rllhereby the arm F', which is on the same shaft F with the arm H, is moved in the direction of the arrow as',
and the rod G is moved in the direction of the arrow m2 and from theA arm M', which it has supported, thus permitting the said arm to swing under the action of its weight M2 in the direction of the arrowa. Thereby the valve L isrturned in the direction of the arrow x3 and brought into position. (Shown in Fig. 2.) `The upper end in the channel S is now closed, and the recess V establishes communication `between the recess I and the upper end of the channel T, permitting the live steam to pass through the channel T to the bottom of the steam-cylinder and below the piston C2 of the water-cylinder C.
I will here state that the swinging of the arm M' in the direction of the arrow m3 does i the position shown in Fig. l.
not move the arm O, and only brings the pin VN2 against the right-hand end of the notch or slot N' in the sleeve N, from which the arm O projects, the arms R and P' remaining in The live steam, passing into the bottom of the steam-cylinder, forces the piston C2 and the water-cylinder on the same upward, whereby the water in the neck- D is forced out through the pipe o and into the boiler through the pipe r, the float J beingv kept in the raised position. At the same time the pistons C C2 on the water-cylinder force the exhaust-steam of the previous stroke, and which is now in that space of the steam-cylin der bounded by the upper part of said steanicylinder and the .neck I), out
through the pipe d and into the pipe r or 'm'.
The piston C has a series of apertures, n', through which the exhaust-steam can pass as said piston rises, that part of the steam that passes through said apertures being forced out 0f the steam-cylinder into the pipe d by the top of the bottom'piston, C2. The water-cylinder C continues its upward movement until the top of the bottom piston, C2, strikes the end -of the arm R, and, swinging the same into the position shown in Fig. 2 in `dotted lines, whereby the arm P is moved downward, the rod O is pulled downward and the arm O swung in the direction of the arrow x4. The end of the notch or slot N', acting on the pin N2, turns the shaft M in the inverse direction of the arrow Q03, whereby the arm M and its weight M 2 are raisedthat is, swung in the inverse direction of the arrow m3. The valve L is thus brought into the position shown in Fig. l. The communication between the pipe 7L and steam-channel T is interrupted, and the channel S is connected with the channel T. i The cylinder C now begins to descend, under the action of. its own weight, and the water still contained therein, thus permitting the .float J to descend,where by the arm F' is moved in the inverse direction of the arrow and the rod G is moved in the inverse direction of the arrow x2. The end of the rod F' is brought against the raised arm M', forming a stop of the same and preventing it from swinging in the direction of the arrow As the water-cylinder and its pistons descend, the exhaust-steam-that is, the steam in the lower part of the steam-cylinder and below the piston C' -is forced up through the channel T, through the recess V of the valve L, and through the channel S in the top part of the steam-cylinder. Just before the water-cylinder completes its downstroke the under side of the upper piston, C', strikes the end of the arm R' swinging the same downward, whereby the arm P' and the rod O are raised, and the arm O is brought into the position shown in Fig. 1 without in any way affecting the arm M. The water now again accumulates in the water-cylinder. After a time the fioat is raised, the arm M is released, the valve L is turned, and the abovedescribed operation repeated.
To adjust the trap for pumping cold water at the same time that it forces the returns into the boiler, the bonnet E is removed, the plug b is removed from the end of the channel a, the top head, A', of the cylinder A is removed, and said plug b isscrewed into the lower end of the channel S to close the same, and then the head A and bonnet E are replaced. The pipe d is now connected with a pipe having opposite check-valves, as shown in dotted lilies in Fig. 2, and connected with the tank or pipe from which the water. is to be pumped-and the tank or receptacle into 'which the water is to be pumped. Then the IOO IIO
IIS
pistons C and C2 descend, they create a vacuum between the inner surface of the cylinder A and the outer surface of the water-cylinder C and the neck D, whereby water is drawn from the tank into said space. At the same time the exhaustesteam below the piston C2 is forced through the channel T, the v'alve L, the channel S, and the channel a into the bonnet, where it is condensed and mixed with the water flowing into and through the neck D.
Then the steam forces the pistons C and C2 and the cylinder C upward, the cold water that has been drawn into th'e space between the inner surface of the cylinder A and the exterior surface of the cylinder C and neck D is forced out through the pipe (l into the receptacle provided for this purpose and can be raised to the desired elevation at the same time the warm water in the water-cylinder C and neck D is forced out in the manner previously described. The pump thus serves at the same time for conveying the water of condensation or returns into the boiler and at the same time pumping' and elevating cold water.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
