LOGOMOTIVE STARTING VALVE.
Application filed June 1,
This invent-ion relates to an auxiliary valve to be positioned on the usual steam chest of a locomotive cylinder, there being provided a pipe establishing communication between the auxiliary valve and boiler of the locomotive so that the entire boiler pressure may be directed to the usual engine cylinders and pistons to facilitate the starting of the locomotive.
The primary object of the invention is to increase the power of the usual steam engine or locomotive, eliminating the necessity of taking up slack in trains, to accomplish the starting thereof.
Another object of the invention is to regulate the stroke of the slide valve to proportion the quantity of steam passing to the cylinder to regulate the speed of the engine.
With the foregoing and ether objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings:
Figure 1 is a side elevational view disclosing a cylinder and setting forth the relation of the valve chamber to the cylinder.
Figure 2 is an elevational view of the valve chamber and cylinder.
Figure 3 is an end view thereof.
Figure 4 is a sectional view taken on line 4-i of Figure 3.
Figure 5 is a sectional view taken on line 5 5 of Figure 2.
Referring to the drawings in detail, the reference character 6' designates a steam cylinder in which the usual piston operates, the I piston in the present showing being omitted. Supported above the cylinder 6 is the usual steam chest 5 supplied with the usual and well known valve, not shown, that controls the passage of steam to the cylinder, in the usual way.
Connected with the main piston is a piston rod 8 which has connection with the cross head 9 operating in the guideways 10, which forms a part of the usual locomotive construction. The drive rod 11 also has connection with the cross head 9, to receive motion therefrom, which drive rod has connection with the wheels of the locomotive to trans- 1922. Serial no. 565,205.
mit motion thereto. The eccentric rod 12 has connection with the link 13 in the usual manner, the link 18 being pivotally supported on the frame of the engine.
Disposed above the cylinder 5 and in communication therewith, is a valve chamber 16, the opening providing communication bctween the cylinder and valve chamber being disposed substantially centrally of the valve chamber as clearly shown by Figure 4 of the drawings, and indicated at 17. This opening I 17 is disposed diametrically opposite the intake pipe 18, which provid s direct communication between the boiler of the engine and valve chamber, so that the entire force of the pressure of the steam within the boiler will be directed to the piston through the valve chamber 16. 1
Operating in the valve chamber 16 is a 7 slide valve 19 which is of the usual construction, the same resting on the lower surface of the valve chamber to open and close the port 17 at intervals, controlling the passage of steam from the boiler to the cylinder 5.
A valve rod 20 has connection with the valve 19 and extends rearwardly having adjustable connection with the arm 21 of the bell crank lever 22, that is pivotally supported on the frame of the engine. The ad.- justable connection between the rod 20 and arm 21, is made through the plate 23 which is formed with a plurality of spaced openings disposed throughout substantially the entire length of the arm 21. A. bolt is carried by the arm 20 at the rear end thereof, which bolt may be moved to predetermined openings, adjusting the stroke of the rod 20 to meet various requirements.
The bell crank lever 22 is operated in the usual manner by the movement of the rod 20 that has connection with an operating lever located in the cab of the engine. Link member 24 has connection with the cross head 9 and also connects with the lower end of the connecting rod 25. Rod 26 slides through the sleeve 26' and operates in the usual and well known manner. m
Due to the fact that the rod 20 has con nection with the arm 21 at a point substantially intermediate the end of the arm 21, it is obvious that when the engine is running the valve 19 will be moved to a position to close the opening 17 thereby allowing steam to enter the cylinder in the usual way.
Supported on the guide bar 27 is a guide block 28 to which the arm 25 is pivotally acting to seat themselves upon return movement of steam from the maincylinder, but open to admit steam to the cylinder, upon movement of the piston 31.
In the operation of the device, assuming that an engine supplied with the attachment is to be started, the rod 20 is moved to move the rod 20 bringing the valve member 19 to a position as shown by Figure 4 of the drawings, whereupon steam passes directly through the valve member 31 through one of the pipes 32 which is in communication with the boiler through the valve member 31, from where the steam enters the cylinder 6 thereby directing the entire steam pressure of the boiler to the cylinder 6 to acton the piston therein.
Should the piston in cylinder 6 rest at the limit of its stroke in the opposite direction,
the valve members 20 and 81 will be moved in the opposite direction, establishing communication between the boiler and opposite end of the cylinder 6 to move the pistons therein.
Having thus described the invention, what is claimed as new is In combination with the cylinder and steam chest of a locomotive, an auxiliary valve cylinder, pipes leading from the valve cylinder and establishing communication between the valve cylinder and the first mentioned cylinder, a valve chamber disposed on the valve cylinder and having an opening establishing direct connnunication with the 1 valve cylinder to deliver steam to the *alve cylinder at a point intermediate the ends of the cylinder, a substantially large pipe having direct communication with the boiler of the loco-motive and having connection with the valve chamber at a point directly opposite to the opening, and a valve tor controlling the passage of steam through the auxiliary valve, and substantially large pipe, direc to the cylinder of the locomotive.
In testimony that I claim the foregoing my own, I have hereto allixed my signature.
