UNITED STATES PATENTOFFIGE HERMAN n. AMBOS, OFOOLUMBUs, OHIO.
IMPROVEMENT ,IN STEAM-ENGINES.
Specification forming part of Letters Patent No. 109,167, dated November 15, 1870.
` To alt/whom it may concern:
f. Beit known that I, HERMAN F. AMBOS, of
. Columbus, in the county'of Franklin and State ot' Ohio, have invented an Improved Steam- En gine for Working lumps; and I do hereby declare that the following .is a full, clear, and
exact description thereof, reference being had` tothe accompanying drawing, making part Lof this specification, in which- .Figure 1 is a diametricalsection through the engine, indicating the interior parts at the commencement'ot' the left-hand stroke. The steamways'in this ligure are all shown by the aid of dotted and full linesin the same plane .its length, showing the.. steamways intheir proper places'. Fig. 'et is an exterior View of the piston-heads, their rod, the ported cylinder and the valve-box.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improved steamengine which is especially adapted for operating pumping-engines.
The invention consists in a novel arrangement of a val ve-box and ported cylinder within -th'e' main cylinder and between two piston heads, n'and also ina novel arrangement of steamways in the main cylinder-shell, where- Y by a regular reciprocating motion is imparted to the piston-rod, and maybe thence transmitted to a pump or other thing to be driven.
It will be hereinafter shown that all the mechanism for alternately cutting oftl steam from opposite ends of themain cylinder is contained'within the .shell of this cylinder, and between the two piston-heads, and that' this cutting ott' and letting on of steam at proper timesis effected by the direct action of the piston-heads upon a ported endwisemoving box or slide-valve.
To enable others skilled in the art to understand my invention, l will explain its construction and operation.
In the accompanying drawing, A represents a steam-cylinder, which is cast with a number riphery.
ot' inlet and exhaust passages or ports, here.- inafter explained, and provided with heads B B, 'through one of which and a vstuffing-boit, a, the piston-rod G passes. This cylinder Ais smoothly bored ont, and has fittedwithin it two pistonheads, D D, which are secured on v the rod C at the proper distance apart, regulated by the length of the cylinder A.-
1n the shell of the cylinder A stealpways are formed, as indicated'in the drawing.
There are two steamways, cl d, for the entrance of steam at opposite ends ot the'eylinder A. From the outlet J there are two steam ways, d d', which cross eachother at the -middle of the length of the cylinder, as indicated by dotted lines, Figs. l and 2, for the escape of exhaust-steam from opposite ends of the cylinder Ato the outlet- J; and there are also two steamways, e f, the offices of which will be hereinafter explained.
Between the .two piston-heads D. D is a ported cylinder, E, which -is bored through and iitted to work endwise and-steam-tight in the cylinder A. This cylinder E is turned so as to form an annular recess into its periphery, which recess leaves annular shoulders at Y its ends, as shown in Figs, l, 2, and 4. Ports of right-angular form are made into the cylinder E, -leading from the peripheries of the shoulders above mentioned'into the annular recess which is between these shoulders. The -two ports c c are at certain times caused to register alternately with the extremities of the steamway f, and the two ports c' c are .at certain times caused to register alternately with the extremities of the steamway e. Between the annular shoulders of cylinder E, and tit! ted snugly but loosely around this cylinder, is
va cylindrical endwise-movable valve, F, hav-v ing twol chambers, g g', formed into its pe- Thisvalve F is shorter than the length of space between the shoulders of cylinder E, to allow ofthe said'endwise 1novement; and thevends of this valve are smoothly dressed, so-that when it is in contact with veither one of the said shoulders it will tightly close the angular ports c c therein. The circumference of -valve F Works steam-tight 1n contact with the-inner surface ot' the cylinder A. The-ported cylinder and its valve are arranged at the middle of the length of the main tossica' left hand. NVhile this is taking place the ex-v hanststealn will escape from theopposite end otl the cylinder A, through the left-hand steanif way, di, into valve-recess g', and ont through pipe J At the saine time the left-hand port, c, will be in communication with valve-recess g, and t-he ri gl it-hand port., c', will be in communi l cation with valverecess` g', as shown in Fig l.
\Vhen the pistons have nearly completed their left-hand stroke, the right-hand piston will move the cylinder E until the right-'hand port, c, registers with the steanlwayf, and the lefthand port registers wit-h the steain-exhaust wnyf. Steam will then nieve valve F to the position shown in Fig. 2, and thus open the steannay d on the left ot' the cylinder, and at the saine time open the exhaust-way d on the right ot' the cylinder, which will cause the pistons to make a return stroke.
Thus it will be seen that the ported cylinder E is operated nlternateli)v by the pistons, to allow steam to n-etupon the slide-valve F, which latter alternately opens and shuts the steam inlet and outlet ways or ports. The lirst movement which takes place is that of the pistons; Jhe second, that of the ported cylinder; third, that of the valve, which latter reverses the direct-ion ot' the stealnenrrents, and thus changes the direction of movement of the pistons,
' Iny the cross-section, Fig. 3, I have shown the sten-neways in the proper relation to each other land to the valverecesses; but, as previouslyT stated, I have indicated all the steamways in the saine plane in Figs. l and 2 merely to facilitate the description. In Fig. 3 I have also shown two screws, S S', which prevent the valves and their ported cylinder from turning' about their axis, but allow them to re-` ceive free endwise movement.
Having described my invention, what I claini as new, and desire to secure by Letters latent, is- A l. The cylindrical valve F, recessed and applied to the shouldered and ported cylinder E, said valve and cylinder being arranged between piston-heads D D, and within a cylinder which has steamways arranged substantially as described.
'2. The exhaust-ways d d', crossed as described, in combination with the valve F. ported cylinder E, and piston-heads l) D, substantially as described.
