REVERSlNG-VALVE.
SPECIFICATION forming part of Letters Patent No. 646,703, dated April 3, 1900.
Application nea october 25,1899. serial No. 734,712. (No moan.)
To all whom t may concern,.-
Be it known that I, JULIUS KELLER, a citizen of the United States, residing in the city and county of Philadelphia, State of Penn` the motor in both the normal and reversedA positions thereof.
It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.
Figure l represents a longitudinal sectional view of a reversing-valve embodying my invention, showing also a portion of the motor to which the same is applicable. Fig. 2 represents a section on line a: x, Fig. 1. represents a plan view-of Fig. 2, showing the valve in a different position from .that seen in Fig. 2. Fig. 4 represents a side elevation Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawings, A designates an inlet-pipe for the motive fluid, said pipe communicating with the inlet-chamber-B, whose outer surface is engaged or inclosed by the rotatable member sleeve or valve C, which latter is preferably threaded at D and adapted to be locked in the desired position by meansv of the lock-nuts E. The inlet-chamber Bis provided with the ports F vand G, the former of which leads through the passage H to the inlet-chamb'erJ of any suitable motor, as K, the exhaust from said motor taking place through thepassage L and passing thence through the passage M to the passage N, contained in the sleeve or valve, and thence through the exhaust-passage P to the atmosphere in any suitable manner, it being Fig. 3'
i noted that communication is formed between the passages F and H by means of the passage or bridge Q in the valve or sleeve. The casing of the passage or bridge Q forms a lprojection on the valve or sleeve C, which is adapted to contact with one or the other of the pins S or T, whereby the movement of the valve is positively limited. It will thus be apparent that when the parts are in the position seen in Figs. 1 and 2 the motive fluid passes through the chamber B and passages F, Q, H, and J to the piston, the exhaust taking place through the passages L, M, N, and P.
When it is desired to reverse the direction of the rotation of the piston, the valve or sleeve O is rotated to the desired extent, whereupon it'will be apparent that the di rection of flow of the motive fluid will be immediately reversed, attention being called to the fact that the motive iiuid passes through the sleeve or valve in its passage to and from the motor in b oth the normal and reversed positions thereof.
It will be understood that while my invention is capable of general application the same is especially adapted for use in conjunc-I tion with pneumatic appliances wherein the valve C constitutes a handle which is grasped by the hand of the workman. It will thus be seen that this handle or sleeve being always in the grasp of the workman affords a most convenient appliance for reversing, this result being attained by a slight movement of the hand, so that the Workman is not coinpelled to release his hold of the tool in order to operate the valve', as is the case in priorl constructions, where the valve consists of a plug operated by an external handle.
It will be apparent that various changes may be lnade in the art which may come Within the scope of my invention, and I therefore do not desire to be limited in every instance to the exact form I have herein shown and described.
I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters IOO direetion, the motive iiuid passing through said member in its passage to and from the motor in both the normal and reversed positions thereof.
2. In a reversing-valve, an inlet-chamber, a rotary sleeve mounted thereon, and passages in said sleeve for permitting the inlet or exhaust of the motive uid in either direction, the motive iiuid passing through said sleeve in its passage to and from the motor in both the normal and reversed positions thereof, in combination with stop devices for limiting the extent of movement of said sleeve.
3. In a reversing-valve, an inlet-chamber, a rotary sleeve mounted thereon, inlet and exhaust passages, ports in said sleeve for permitting the inlet and exhaust of the motive iuid in either direction, said fluid passing through said sleeve in eaoh direction in both the normal and reversed positions thereof, and means for looking said sleeve in the desired position.
4c. In a reversing-valve, an inlet-chamber, a communication therefrom to the interior of a motor, a movable sleeve mounted on said chamber, an exhaust-passage leading from said motor, a main exhaust from the latter, and passages in said sleeve for causing the above ports and passages to serve as inlet or exhaust passages according to requirements, the motive fluid passing through said sleeve in both the normal and reversed positions f thereof.
6. The combination of an inlet'ehamber, ports leading therefrom, a movable member mounted thereon and having passages therein whereby said ports are adapted to serve as inlet or exhaust passages for the motive fiuid, the latter passing through said member in its course to and from the desired point in both the normal and reversed positions thereof.
7. In a reversing-valve, an inlet-chamber, a rotatable sleeve mounted thereon, ports and passages common to said chamber and sleeve, and means for enabling said ports and passages to serve as inlet or exhaust passages aoeording to requirements, the motive fluid passing through said sleeve in both the normal and reversed positions thereof.
