THE NORRIS PETERS cc, wAsnwsmu n c FREDERICK J. HUMPHREY, OF KALAMAZOO, MICHIGAN.
WATER-MOTOR.
Specification of Letters Patent.
Patented March 3, 1908.
Application filed July 17. 1907. Serial No. 384.272-
To all whom it may concern:
Be it known that I, FREDERICK J. HUM- PHREY, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in \Vater-Motors, of which the following is a specification.
This invention relates to improvements in water motors.
The main objects of this invention are, first, to provide an improved water motor which will perform a maximum amount of work with the power consumed; second, to provide an improved water motor which has a regular, even movement and one which may be started with the movable parts in any position which they may assume therein; third, to provide an improved water motor in which the shock of reversing is very slight so that the motor is practically noiseless and easy running; and fourth, to provide an improved motor, the parts of which are economical to produce, and easily assembled and disassembled, and reassembled should occasion require the same.
Further objects, and objects relating to details of construction, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification.
The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,
Figure 1 is a detail plan view of my im-.
proved water motor, partially in longitudinal section, to show the structural details and the relation of the parts; Fig. 2 is a transverse section taken on a line corres onding to line 22 of Fig. 1 Fig. 3 is a detai section taken on a line corresponding to line 33 of Fig. 2; Fig. 4 is a detail section taken on a line corresponding to line 44 of Fig. 2; and Figs. 5 and 6 are diagrammatic views showing the relation of the valves and the passage of water through the motor, Fig. 5 showing the position of the valves when the piston is at the left hand end of the stroke with the valves in their reversing position, and Fig. 6.
In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
Referring to the drawings, 1 represents the supporting frame, which is here shown in detail only. The piston cylinder 2 is mounted at one end of the frame and the pump cylinder at the other. The pump cylinder, as it forms no part of this invention, is not here illustrated. The piston 3 is preferably provided with two heads 4, the piston rod 5 being adapted to connect the same tothe pump.
On one side of the piston cylinder is a'main valve cylinder 6 to which the inlet or induction passage 7 is connected. The passage 7 is preferably provided with an annular delivery portion 8 having a plurality of discharge ports 11 through the cylindrical bushing 10 of the cylinder.
The valve cylinder 6 is connected by a pair of passages 12 to the piston cylinder, the passage 12 opening into the piston cylinder at each end thereof beyond or outside of the stroke of the piston. These passages are connected to the main valve chamber by means of the annular passages 13 and the ports 14.
These ports 14 are located at each side of the inlet passage.
The mam valve chamber is connected to the exhaust 15 by means of the passages 16,
which terminate in the annular passages 17 and the ports 18, which ports are located at each side of the ports of the connecting passages 12 for the main valve cylinder to the piston cylinder.
The piston cylinder is connected to the exhaust by a passage 19, the passage 19 opening into the piston cylinder at a point within the stroke of its piston heads. This insures the draining of the piston cylinder and per- --nected to the exhaust, the main piston being at the initial point of its stroke.
The trip valve chamber 23 is arranged parallel with the main valve and the piston cylinder preferably above the pistoncylinder. The trip valve cylinder is connected with the annular delivery portion 8 of the inlet or induction passage 7 by means of the passages 25, 25 and 24. The passages 24 open into the trip cylinder at the outer ends thereof. The passage 25 is, for convenience in manufacture, in the form of a groove in the bottom of the casting, as illus trated in Fig. 4, and serves to connect the passage 25 to the passages 24. The trip valve cylinder is connected to the main valve cylinder by means of the passages 26 which open into the main valve chamber at points beyond the stroke of its valve, so that the water may'pass through the passages 24. to the trip valve chamber, thence through the passages 26 to the outer end of the main valve cylinder for actuating the main valve, which in turn controls the passage of water to the main cylinder, as described, and connects the same with the exhaust. The trip valve 27 is provided with a pair of heads 28 adapted as the trip valve is shifted to alternately connect or disconnect the passages 2.4 and 26. This trip valve is actuated from the piston, being preferably provided with a tappet. pin 29. projecting through a suitable slot-like opening 30 into the piston cylinder, (see Figs. 2, 3 and 4,) so that it is. engaged by the heads 4 of the piston as the same reciprocates, thus shifting the trip valve, which in turn controls the main valve, which in its turn controls. the piston, as has been described.
The water from the ends of the main valve cylinder exhausts through the passage 26 and the trip valve chamber and into the piston cylinder through the slot 30 provided for the tappet, the water escaping from the piston cylinder through the passage 19, as described.
The piston valve cylinders are preferably formed of two castings divided on the line 3-3 of Fig. 2, which enables the easy forming of the passages as described, either by means of cores in the casting or by drilling and cutting away. This arrangement facilitates the manufacture and also affords ready access to the parts in case it is necessary to disassemble for the purpose of repair or the like.
My improved motor is as stated comparatively economical to produce and may be readily assembled or disassembled, as stated. The motor may be readily started by the turning on of the water, no matter in what position the movable parts may be, as it is impossible for them to become so located but that the main valve will be shifted in one direction or the other.
My improved motor is reversed with comparatively little shock, so that it is comparatively noiseless. I have illustrated, and described the same in detail in the form preferred by me on account of its structural simplicity and economy. I am, however,
aware that it is capable of considerable vari-.
