EL OW-VALVE FOR HOT-WATER RADIATORS SPECIFICATION forming part of Letters Patent No. 6&2,199, dated January 30, 1900.
Application filed July 13, 1899. Serial No. 723,667- (No model.)
T0 ail whmn it may concern.-
Be it known that we, WILLARD E. BLAKE and RANDALL B. Annnos, citizens of the United States, residing at Boston, Suffolk county, Commonwealth of Massachusetts, have invented anew and useful Improvement in Elbow-Valves for Hotater Radiators, of which the following is a specification.
Our invention consists in combining a curved waterway with a plate or damper having an axial oscillation and with devices for operating the same and in constructing and adapting the same for said apparatus and use.
Our invention will be clearly understood from the drawings, in which- Figure 1 is an external plan. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is a vertical section on line 3 3 of Fig. 2.
We will now describe the drawings.
A represents the pipe-angle, into which a connecting-pipe screws at a. Onto the part ct (shown in Fig. 1 as connected with Aby a union-joint) is screwed the other connecting- The pipe-angle A is intentionally made in the form shown in order to secure the easy flow of the water by a curved surface and to avoid deposit of sediment.
B is a plate or damper of not quite the diameter of the pipe-angle A, the difference being intended to admit of a continuous circulation of a sufficient amount of the water to prevent freezing. Instead of this lesser diameter of the damper the same result may be secured by perforating the damper or by cutting off a small segment from the edge. The damper-plate B swings on the handlerod b, which terminates in the spindle h.
C is a housing or stuffing-box, which screws onto the projection a of the pipe-angle A and has the space 0 for the packing.
The handle or key forturning the damper is D, having an extended shank d, so situated that it may be operated by the foot, and also having the edge d, which rides back and forth on the ledge or track a of the pipe-angle A, said track having three stops at right, left, and center. The screw E fits down into the spindle b and holds the handle D in place. Upon the ledge or track a of the pipe A are placed three stops, between two of which the edge (1' oscillates, according to which side of the center stop it is placed. In the position shown in Fig. 2, with the valve open, the key D has reached the end of its swing and the edge d rests against a stop. When the valve is to be closed, the key D will be swung through one-quarter of a circle, and at that point d will come in contact with the first stop upon the track a The handle may swing in either of two directions; but it will be necessary to deter mine in which direction it is to swing before fastening it by the screw E.
The three stops shown at each extremity and in the center of the segmental track (1. are to control the swing of the valve B, first,
as to the direction in which it shall swing,
and, second, as to the extent of the swingingnamely, one-quarter turn, which either opens or closes the valve. It will be seen from Fig. 1 that the valve-handle D must swing to the right and cannot swing to the left, because it is already against the center stop; but the angle-pipe might be in such position that it was desirable for the handle D to swing to the left of said drawing, in which case it would be necessary to remove the handle I) from the stem 1) and place it so that said handle, when the valve is open, would rest against the opposite side of the center stop from that which it now rests against.
The elbow or pipe-angle A is so constructed that the area of the inside diameter is equal to the inside diameter of the pipe of the size which it is designed to accommodate, and so has no chamber for the accumulation of either air or sediment. It will be seen that the stuffing-box 0 serves the double purpose of holding the damper-rod in place and of making a tight joint. 7
Having described our invention, What we claim is- In a hot-water-radiator valve, the combination of the angle-pipe A having the track 0. and the projection (t the damper-plate B constructed to admita continuous circulation of sufficient water to prevent freezing, the rod b,b, the handle D having the parts d, d, prop erly connected with said damper-plate rod, substantially as described and shown.
In witness whereof we hereunto set our hands this 10th day of July, 1899.
WVILLARD E. BLAKE. RANDALL B. ANDROS. In presence of- W. STANLEY CAMPBELL, JOSEPH B. SHEA.
