HORACE BARTINE -l MARTIN, or sAN FRANCISCO,4 CALIFORNIA.
l Letters Patent No. 87,419, dated M arch 2, 1869.
IMPRQVEMENT IN OSCILLATING'ENG-INES.
The Schedulevreferred to in these Letters Patent and making part of the sam ,1:0 all whom it may concern.- y
Be it known that I, HORACE BARTINE MARTIN, of
San Francisco, in the county of San Francisco, and
State of California, have invented a new and useful Improvement in Steam-Engines; and I do hereby declare'that the following is a full, clear-,and exact description thereof,-which will enable others skilled in the art to make and use the same, reference being had to the vaccompanying drawings, forming part of this specification, in which- I Figure 1 represents 'a vertical longitudinal section `of my improved steam-engine.
Figure'2 is a top view, partly in section, of the same( Similar letters of reference indicate like parts.
This invention relates to improvements in oscillating steam-engines; and v 4It consists in the peculiar arrangement of the tubu- 'lar valve and its' ports, with reference to the semider, so asto force one pistou toward the end, the other piston wil follow, and the weight of the yoke and ofthe pistons is gradually carried toward one end of the cy1- inder, and when the balance is overcome, the weighted end drops down, thereby reversing the parts, letting thesteam into the upper end of the cylinder.
The cylinder is, in the middle, crossed by a somewhat conical cylinder, A, which turns in suitable bear` ings, and'which has the ports for the inlet and dischargev of steam.
Through the cylinder A fits a pipe, which is divided by a partition, and of which one end serves to let steam into the main cylinder, While through its other end the exhaust is carried off.
A, in the drawings, represents a cylinder ofv somewhatleonical forni.
B B; and .has perforated sides, as shown.
Around the cylinder Ais formed a jacket, O, which is rigidly secured, with its ends, tothe cylinder, and which forms two nearly semi-annularchambers, a a', around the cylinder, as in fig. l. l.
The lperforations b, b', c, and c', that are foi-medi'y through the cylinder, all communicate with the chaine v ber a, Y
To the jacket U are secured, on opposite sides, and each other, two projecting cylinders, D i
in line ywith and E.
-. In each cylinder is arranged a piston, F, the pistons `being attached to'rods G G, respectively,-tliat fitthrough the outer heads of their respective cylinders. The outer ends of the piston-rods are secured to a yoke, H, so that the pistons must move simultaneously Thiscylinderihasfits bearings in suitable supports, l
in the same direction. The yoke .lits against opposite sides of the cylinders, to have a guidance andl to steady the pistons. y
One end of the yoke H may, by means of a crank, d, be connected with the shaft I that is to be rotated.
Through the cylinder `A is fitted a conical tube, J, which is perforated on both sides of a partition, e, that is arranged across it, as is clearly shown in iig. 2.
The apertures f,f, g, and y', through the pipeJ, are arranged so that two, diagonally opposite eachother, are always in the same relation to the apertures in. the cylinder A, next tothem. v
Thns,"when thecylinder Dis down, t. e., below the level ofthe axis of A, the ports f and g will be closed, and not in communication with the vchamber a, while those, j and g, are open, and communicatewith the chamber a. p.
The steam or other Huid, entering the pipe J atthe end, h, in which the portsff are arranged, will then kb', into the chamber u', and thence into the cylinder E, forcing the piston toward the outer .end of such cylinder. The yoke will follow the motion of such piston, and will draw the piston in the other cylinder I), in the same direction. I
This latter piston forces the steam contained in B out through the ports c g.
When the yoke and pistons have so far travelledinl one direction that the swingingapparatus finds its equilibrium, it will swing to alevel and close all the ports, but then the fly-wheel will carry the shaft around suficientlyv far, and move the yoke sufficiently, to
the cylinder E, downward.. Thereby the portsb'j" and c g will be closed, and b fand c' g are opened, so that steam enters D and leaves E.
In' this manner the machinery will be kept going, swinging constantly around the fixed pipe J.
made to fit tight into the inside of A. v
By slightly turning the pipe, or tumbler, J, the arrangement of ports may be reversed, so as to reverse the machine.
down, the pipe J may be so turned thatthe port-s bf and c' g' may be open, and b f-, 'c y, closed. This, it
will .be noticed, is the reverse to the position of shown.
This engine may be advantageously employed, for pumping and other purposes, as an engine or pump.'l
Having. thus described my invention,
ports Patenti ports g g', ff', with 'relation to the ports b b', c c', and the semi-annular spacesa a', as herein shown and deonly be able topass through the then open ports, f',
cause the yoke to lose the equilibrium, and to tip', with The latter beingconical, as shown, can always be Thus,lin the position shown in iig. 1, when D is' I claim as new, and desire to secure by Letters The arrangement of the tubular valve ,L having its
