Specification of Letters Patent.
Patented June 22, 1915..
Application filed May 4:, 1914. Serial No. 836,208.
To all whom it may concern Be it known that I, NATHANIEL JOHNSTON PRrrorrARD, a citizen of the United States, residing at Point Richmond, in the county of Contra Costa and State of California, have invented-certain new and useful Improvements in Micrometer Pump Valve Gages; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in valve gages and the primary object of the same is to provide a device of this character which may be simply and inexpensively constructed and which will accurately determine the amounts of lift of various valves with which it is designed to be used.
A secondary object of the invention is to construct the entire device in the most simple manner consistent with its proper operation.
IVith these objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:
Figure 1 is a vertical section through one of my improved gages showing the same applied to a valve at the top of an air cylinder; Fig. 2 is a vertical section taken at right angles to Fig. 1, the valve cap being removed; Fig. 3 is a side elevationof the gage detached; Fig. 4: is a top plan view; Fig. 5 is a vertical section through the lower part of an air cylinder showing the form of gage used in connection therewith; Fig. 6 is a side elevation of this form of gage; and Fig. 7 is a top plan view thereof.
In the accompanying drawings, from Figs. 1 to 4, inclusive, I have shown my improved gage as including a substantially rectangular base 1 which is notched on its opposite lower corners as at 2 to provide shoulders which are disposed directly beneath upright arms 3 which rise suitable distances from the top of said base. The base 1 is provided with a central upright bore which is threaded throughout its length for the reception of a gage screw 4, the latter being provided with an enlarged head 5 on its upper end. The base 1 is further provided, in its upper surface, with a recess or notch 7 which is adapted for the reception of a lock nut 65, the latter being threaded upon the screw d between its head and the base.
The operation of the device, so far described, is as follows: The usual valve cap C, having the usual stop S and annular flange F, is removed from the valve casing c of the air cylinder. The gage is now positioned upon the cap C and the upper ends of the arms 3 are engaged with the lower surface of the flange F whereupon the screw 4; is rotated until its head 5 contacts with the depending stop S, after which the lock nut 6 is tightened to retain the parts in this position. The gage is now seated upon the valve casing c with its notches 2 engaging the portions thereof normally engaged by the flange F. If now the lower end of the screw contacts with a stop 8 on the valve V, it will be understood that said stop is of the necessary height and that the valve should, therefore, properly operate. If however, the lower end of the screw 4 does not contact with said stop, it will be understood that the latter has become worn and should either be repaired or replaced by an unworn stop or an entirely new valve. If the stop is to be repaired, the screw 4: is now rotated until it contacts with said stop, the distance which said screw descends being the amount of material which must be added to the stop 8.
In order that the amount of movement of the screw 1 may be accurately determined, I provide the head 5 with a number of graduations 5 which co-act with similar graduations 1 on the base 1. In constructing the device, the threads upon the screw 4. are preferably pitched 16 to the inch, it being therefore clearly seen that if the screw is rotated one quarter of a revolution, the amount of its ascent or descent will be one sixty-fourth of an inch. Thus, it will be seen that the amount of movement of the screw may be readily and accurately determined and that the device, although simple in construction, becomes very eflicient in operation.
It may here be explained, that the cap G is removed from its engagement with the arms 3 when the amount of movement of the screw 1 is to be ascertained by the graduations 1 and 5*.
From Figs. 5 to 7 I have shown the form of gage which I employ in connection with the valve casing c at the lower end of a pump cylinder. In this application, the base 1 is reversed and its notches 2' are engaged with the lower end of said casing, the arms ,3 being lengthened in this appli.
cation and depending from the base. In
, against movement. The gage may now be removed from the valve casing and positioned upon a removable valve seat S with its arms 3 contacting with the flange F of said seat. If the lower end of the screw 4' new contacts with the stop s on the valve V, it will be understood that said stop a is of the proper height and needs no alteration, If, however, the contacting of the screw with the stop prevents the arms 8 from contacting with the flange F, it will be understood that the stop is too long to allow the valve to raise or lift to the proper eXtent. The screw 4: may, therefore, be rotated until the parts assume their correct positions, the amount of movement of said screw being determined by coacting'graduations 1 and 5 which arecarried respectively by the base 1 and the head 5.
From the foregoing description taken in connection with the accompanying drawings, will be seen that I have produced an extremely simple valve gage, yet one which will readily perform the functions for which it is designed.
I may here explain that my invention constitutes a standard gage for adjusting air valves and isprimarily designed for the adjustment of the valves of Westinghouse 'p' np What I claim as new and desire to secure by Letters Patent, is:
1. A valve lift gage comprising a sub stantially rectangular base having transverse notches in the opposite ends of one of its sides, said notches being adapted to be positioned on the edge of a valve casing, a pair of arms projecting at right angles from the opposite side of the base and adapted to receive a valve cap, and a gage screw threaded through said base and having a stop engaging head on one end, said screw lying parallel to said arms and being spaced equi-distantly therebetween, there being coacting indicating characters on said head and adjacent sides of the base.
2. A valve lift gage comprising a rectangular base having transverse notches in opposite ends of one of its sides, said notches being adapted to be positioned upon the edge of a valve casing, a pair of arms projecting at right angles from the opposite ends of the opposite side of said base and having their inner sides channeled longitudinally on a radius struck from the center of the base, said arms being adapted to receive a cylindrical valve'cap, and a gage screw threaded through the center of the base and lying parallel with said arms.
3. A valve lift gage comprising a rectangular base, a pair of parallel arms project ing from opposite ends of one side thereof and having their inner sides channeled lon- V gitudinally on a radius around the center of the base, and a gage screw threaded through said base and parallel with said arms.
4. A pump valve gage comprising a horizontal base, a pair of upright arms projecting therefrom and lying in parallel relation, said arms being of equal length and being formed integrally with the base, and a single gage screw threaded through the center of said base and projecting centrally between said arms, there being coacting indicating characters on the screw and on the base for the purpose set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit- 'nesses;
, NATHANIEL JOHNSTON PRITCHARD.
