sPncIFIcATIoN forming part of Letters Patent'No. 287,363, dated Nwember 6, 1883.
Application filed August 17, 18l3.` (No model.)
To ail whom tim/ay concern:
Beit known thatl, CONRAD RosINE, a citizen ofthe UnitedStates of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to certain new and usei ful improvements in steam-pumps. The object ity has in view is to'afford simple and convenient means for the admission of live steam to the steam-cylinder, for the operation ofthe p piston and plunger, and to allow of the escape of the exhaust-steam from said/cylinder; and tothe accomplishment ofthe above the invention consists of certain novel devices and combination o`f devices, as will bev described and claimed. A
Reference will be made to` the accompanying drawings, in which Figure lis a sectional view of a steam pump and cylinder; Fig. 2, a sectional view, on an enlarged scale, ofthe piston-valve,`and showing part of the piston and piston-stem', Fig. 3, a sectional view on or ring, c, against which the piston-valveF strikes, aswill be described. Y
The piston-stem G, Iforin of ahollow-tube, and itis made in two sections, each of which is preferably provided with an exterior screwhead C and the outer end of this section, moves screwLthreaded opening in piston H.
thread upon its inner end and screwed into a A partition, b, formed in- 'piston H, separates the inner ends of the sections, and at the point shown each is provided with a suitable opening, one of lwhich admits live steam to the cylinder and the other allows of the escape of the exhaust-- steam therefrom. One section of piston-stem G passes through a stuffing -boX, O, and a screw-threaded gland, P, secured to cylinderin the supply-pipe R. The other section of I the piston-stem passes through stuffing-box Q, secured to plateE; thence through the pumpcylinderand through a stuffing-box, N, and
screw-threaded gland P', secured to head D, the outer end of thissection moving in exhaust-pipe S. v *y A plunger, .Lis secured to Vthe piston-rod at a suitable point within the pump-cylinder. The openings described as formed in the piston-stem communicate one with a supply-port, n
f, and the other with an exhaust-port, g, both formed in the piston'H, said ports'communieating, alternately, withV other steam -ports formed in the piston-valve, and now to be re` ferred to. Formed in this valve are two ports,
will always have communication'with either the supply-port f or the exhaust-port g of the piston. Both of these ports h h open into a port, c', which extends from s'aid port h to the opposite side or end of the valve, where it opens into the steam-cylinder. Situated midway between ports h h is a' circular port, j, the location of this last-named port causing` it to 'communicate with the exhaust-port gwhen the port h communicates with the supply-port f, and with the supply-port f when the port Itlr communicates with theY exhaustport g. Port j communicates with a port, k, which opens into the steam-cylinder on the opposite sideof .the piston H to thatv into which port t' opens. 1 Y
is provided on its upper-face with a groove,
d, into which the lower end of a pin or screw, c, is. inserted, said screw being inserted into a suitable -opening made through the piston-r ring c and the piston for that purpose. This constructionserves to` limit the movement-of the valve. Y
. The pump is provided with suitable pumpcylinder ports, Z, suction-valves L, suction-port K, discharge-valve M, and air-chamber L', all of ordinary construction.-
T represents suitable discharge-cocks for the escape of surplus steam from cylinder A.
The operation of the device is as follows: Live steam is admitted through supply-pipe R to piston-stem G, whence it passes through the opening made in said piston-stem to the supply-port f of the piston. When the piston- IOO valve is in the position shown in Fig. l of the drawings, this supply-port f communicates with the port h of the valve, and the steam escapes through said port to port fi, whence it passes into the steam-cylinder. The chamber formed by the piston and cylinder-head C is thus filled with live steam and the piston set in motion. At the end of the piston-stroke the valve F comes in Contact with the ring or iiange a of plate E, and the position of the different ports and their relation one to the other changed as follows: The port 1L of the valve is closed, the circular port j is brought into communication with supply-port f of the piston, and the port h', which during the first part of the operation was closed, communicates with the exhaust-port g of the piston. By this operation the exhaust-steam in the cylinder is allowed to escape through ports z', h', and g to the piston-stem, whence it is carried off through exhaust-pipe S, and live steam is admitted through ports f, j, and k to the opposite side of piston Hand the motion of the piston reversed.
It will be understood that when the parts are in the position first described any exhauststeam in the cylinder escapes through ports k, j, and g, which then communicate.
The advantages I claim for my device are that it is simple in construction, perfect in its 3o operation, and inexpensive;
4Having thus described my invention, what I claim as new therein, and that for which I desire to secure Letters Patent, is-
l. The combination, with the piston H and 35 screw c, passed therethrough, of piston-valve F, provided with groove cl, as and for the purpose set forth.
2. The piston-valve F, provided with steamports 7L, 7L', i, j, and 7c, in combination with the 4o piston H and hollow piston-stem G, saidpiston provided with supply and exhaust ports fg, and the piston-stem provided with suit- 4exhaust-steam allowed toescapeLas described and shown. l
In testimony whereof'I affix my signature in 5o presence of two witnesses.
CONRAD ROSINE.
