SPECIFICATION forming part of Letters Patent No. 622,267, dated. April 4,1899.
' Application filed December 5, 1898. Serial No. 698,288. (No model.)
To all whom it may concern:
Beit known that I, ANDREW J. ROBINSON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Valves, of which the following is a full, clear, and exact description.
In an application for patent filed by me November 21, 1898, Serial No. 697,029, I have shown and claimed a valve which is operated by means of a spindle carrying an antifriction device comprising a rod-like roll contained in a cylindrical recess extending longitudinally through the spindle. In this present construction I have sought to devise a cheaper and more easily-formed arrangement for enabling the spindle to carry the rod-like roll. This construction is illustrated in the drawings forming part of this specification, in which-- Figure 1 is a vertical central section of the complete valve and easing, showing saidspindle in section. Fig. 2 is a side View of the spindle alone. Fig. 3 is a longitudinal section of the spindle with the roll removed. Fig. 4 is a transverse section at X X in Fig. 2, and Fig. 5 is a similar section at Y Y in Fig. 3.
Referring to Fig. 1, A is the casing of the valve, and a the outlet and B the inlet pipe joined to the casing by a suitable union O. The valve proper, F, is supported by the tube E, which in turn is raised by the cam-surface m. Said cam-surface being carried by the spindle L, as shown more clearly in Fig. 4, the rotation of such spindle causes the tube E to be raised and lowered and the valve F to be raised and lowered from and to its seat D. To render said cam-s urface substantially without friction, I have devised the improvement constituting the subject-matter of this application.
The spindle L turns in the bearings a, being inserted therein from one end and held in place by forked arms, as shown in my companion application above referred to. The central portion of the spindle is constricted, as at L in Figs. 2 and 4., while the terminal portions thereof fit said bearings a. Extending longitudinally along the periphery of the spindle, but not quite to the ends thereof, is
a groove or recess L (Illustrated in Figs. 3 and 5.) This groove or recess is preferably formed by casting the spindle in such shape and then finishing the surface thereof afterward. Of course said groove may-be milled and drilled from the solid metal, but by thus formingit integrally with the spindle and smoothing it up afterward is much less expensive and more satisfactory. Said groove having been made, the rod or cylindrical roll.
m is dropped therein and then both spindle and roll put into place. As shown in Fig. 1, the length of said groove and roll is such that each end of the roll comes within the bearing a, and is thereby held within the groove. Were the roll less in length than the distance between the bearings, it would immediately drop out from its groove whenever the spindle should be turned over. On the other hand, it will not do for the groove and roll to extend the entire length of the spindle, for then the water would escape from between the roll and the sides of its groove, rendering the same untidy and objectionable.
What I claim as my invention, and for which I desire Letters Patent, is as follows, to Wit:
1. The combination of the casing, the valve and the spindle rotative in bearings in said casing and formed with the longitudinal groove in .its periphery extending nearly but not quite to its extremities, and the cylindrical roll loosely fitting in said groove and -29th day of November, 1898.
