HYDRAULIC ENGINE.
SPECIFICATION forming part of Letters Patent N 0. 472,942, dated April 12, 1892. Application filed February 13,1891. Serial No. 381.300. (No model.)
To all whom it may, concern.
Be it known that we, HARVEY F. CRAW- FORD and RICHARD (J. LAMBERT, of Brockton,
county of Plymouth, State of Massachusetts, 5 have invented an Improvement in Hydraulic Engines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. IO This invention has for its object to produce a novel hydraulic engine.
In our invention we employ a pair of hy-' so rotate the shaft, all as we will proceed now more particularly to set forth and finally claim.
draulic engine embodying this invention; Fig. 2, a top or plan view of the same, partially broken away; Fig. 3, a sectional detail showing the clutch mechanism to be described, and Fig. 4 a modification to be referred to.
Referring to the drawings, the bed A, of suitable shape and construction to sustain the various parts, supports at or near its middle the pillow-blocks A A A each contain- 3 ing a series of rolls which form bearings for the main crank or driving shaft B, having fast upon its opposite ends the fiy-Wheel F and driving-pulley D. (See Fig. 2.) toothed wheels I) b are loosely mounted upon the shaft B at opposite sides of the middle pillow-block A they having fast to or formed as a part of them the ratchet-toothed wheels 1) b engaged by spring-controlled pawls a a, pivoted at a in the heads a of the hubs a, 5 fast on the shaft B. The toothed wheels I) b are engaged above and below, respectively, by the rack-teeth upon the inner sides of the piston-rods c 0', fast to and moved by the pistons c c in the hydraulic cylinders O O, sup- 5o ported by the bed A. The bed A and pillow Figure 1 represents in side elevation a hy- Two block A are provided, respectively, with guide-rolls 1O 12 (shown in dotted lines, Fig. 1) to keep the rack-teeth on. the piston-rods c o in engagement with their toothed wheels. The cylinders O are provided with chambers (represented as formed of tubes) O 0 curved over to face each other, and the said tubes are fitted with plungers Of O arranged at the oppositeends of the plunger-rod O, which rod at or near its middle is herein shown provided with a laterally-extended stud C, (see Fig. 2,) to which is'journaled the outer end of the piston-rod E, connected with and moved by the piston E in the steam or power cylinder E supported in suitable manner by the bed A. The steam or power cylinder E as usual, is provided with a steamchest E3, in which is placed a suitable valve or valves to control the admission of steam to the steam-cylinder E we having herein represented a main slide-valve V, (shown in dotted lines, Fig. 2,) upon the back of which slidesthe cut-off valve '0,- the said valves being actuated by valve-stems V 1:, connected by links 12 with the actuating-lever b at opposite sides of its pivotal center If, the said lever being pivoted or mounted on a boss raised upon the pillow-block A. ating-lever b has at'its outer free end a slot '0 which receives a stud o on the plungerrod 0 movement of the plunger-rod communicating the proper movement tothe valves V Q) through the lever b Any other desired mechanism may be employed to move the valve or valves, which may be of any desired form or kind other than the particular ones shown. Steam being admitted to the corresponding reciprocating movement to the plunger-rod O and plungers O 0 which will force the water or other fluid contained in the chambers or pipes O O alternately into the cylinders .O O behind their pistons 0 c causing the same to be reciprocated. When the pistons c c are reciprocated by movement of the plungers O 0 the toothed wheels andtheir ratchet-wheels are given a rotary reciprocating motion by the rack-teeth on the piston-rods, the ratchet-wheels co-operating with The actu:
steam-chestE the piston E in the steamcylinder will be reciprocated,transmitting a the pawls a a to turn the shaft B in the direction indicated in Fig. 1. As the piston f the steam-cylinder acts on the small plungers- C C Whl(l1 in turn force the fluid into the hydraulic cylinder behind the pistons therein, great power is obtained, which can be utilized to advantage in a variety of Ways,
- We do not limit this invention to the particular clutch mechanism shown, as any other suitable clutch mechanism may as well be employed, and even a crank may be substituted for the clutch mechanism, if desired, the pistons beingconnected to a crank B on the shaft B by usual connecting-rods 0 0 as represented in Fig. 4.
If desired, two or more power-cylinders may be employed.
We claim 1. A bed, the hydraulic cylinders O C", mounted thereon and having pistons, and the In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
