AUTOMATIC WATER RELIEF VALVE Specification of Letters Patent;
Patented Sept. 8, 1908.
Application filed November 2, 1904. Serial No. 231,043.\
useful Improvements in Automatic Water- Relief Valves, of which the following is a description.
My inventionrelates to that class of devices em loyed upon steam heating systems and the ike to discharge the water of condensation from the radiators or other parts of-the system without permitting a wasteful esca e of steam.
T e object of my invention is to produce a durable and simple device of the kind described that is not liable to become clogged up or otherwise rendered inoperative when in use, and to this end consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.
In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts :Figure 1 is a longitudinal diametrical section of my device. Fig. 2 is an enlarged partial section showing the arrangement of the valve and valve seat shown in Fig. 1. Fig. 3 is an enlarged partial section showing a modified form of valve seat and associated parts, and
Fig. 4 is an elevation of a radiator showing the usual connecting pipes and the usual and preferred location of my device in relation thereto.
In the form of my device shown in the drawings, 1 is the outer shell or casing of myvalve, provided with a removable cap 2, an inlet port or connection 3 for attaching my valveto a radiator or similar device, and an outlet port or connection 4 for. attachment to one of the return pipes of the system. A
tubular head 5, closed at one end, is arranged within the shell 1 with its open end screwed into or otherwise secured at, the opening 4, with the chamber 6 within the head communicatin directlywith the part 4 and by means of t e lateral openings 7-7--With the interior of the shell. A vertically movabletubular-valve 8 is provided to closely fit upon the exterior of the head 5 and when at the lower limit of its travel cover the openings 77 and prevent flu'id passing from the interior of the shell '1 into the chamber .6.
Preferably a plurality offopenirrgs are ar ranged through the wall of the valve above v the head 5 to balance the valve, and permit 7 free access of any air within the casing 1 to the upper end of the head 5 where an air vent 10 may be provided if desired. Preferably a shoulder 11 is provided upon the head 5 below the openings 7, to engage the lower end of the valve 8 and limit its downward move ment, and when desired a flange or roject1on 12 may be formed upon the hea to afford means for engaging the same with a suitable wrench or to otherwise assist in securing the headinto the casing 1.
In the form ofmy device shown in Figs. 1 and 2 the head 5 is reduced in diameter at the openings 7 and the chamber 6 formed to suit. In this construction, when the valve is closed an annular chamber 14 extends around the head 5 communicating with each of the 9 enings 7 and. thus avery slight movement (5 the Va vs 8 will open free communication between-the chamber 6 and the interior of the shell 1. .The form shown in Fig. 3 is similar to that of Figs. 1 and-2 except that the head 5 is not reduced in diameter at the openings 7 to form the annular chamber 14.
Preferably the movements of the valve 8 are controlled by a float 15 to which the valve 8 is directly attached in any suitable manner. The float is preferably provided with a guide or stem 16 projecting at its upper side and loosely engaging a suitable recess 17 in the cap 2 to guide the float and prevent lateral displacement and by the end of the guide 16 contactin with the end of 'the recess 17 limiting t e upward movment of the valve. Obviously any preferred form of float may be employed either closed or open or a combination of a closed andopen according to circumstances. Also if desired a screen 18 may be arranged within the shell 1 inclosing the valve 8 and head 5 as shownto prevent dirt entering at the part 3 from reaching the working parts of my device.
Obviously the head 5 may be made of any desired shape, at its upper end. As shown the. upper end is conical terminating in a spherical end. This form enables the valve to be readily placed in position upon the head, but obviously is not essential to the operation of the device. Also I prefer to bevel the lower edges of the valve 8 so as to bring the bearing surface upon the shoulder 11 at the interiorfs'urface of the tube as shown.
Having thus described my improvement it is obvious that various immaterial modifications may be made in my device without departing from the spirit ofm invention.
What I claim as new, an desire to secure by'Letters Patent'fis.

A device of the ing a shell provided with an inlet and an outlet opening, means for connecting said shell into a heating system, a chamber arranged within said shell inclosing said outlet opening, provided with one or more ports formed through its wall, and having a recess formed in said wall extending around said chamber at said ports, in combination with a tubular valve inclosing a part of said chamber, by its position controlling said ports by covering said recess, and afloat attached to said valve adapted to control its position.
2. A'device of the kind described, comprising a shell provided with an inlet and an outlet opening, means for connecting said shell into a heating system, a chamber arranged within said shell inclosing said outlet opening, and provided with ports formed through the side wall, and with an air vent through the -end wall, of said chamber, in combination with a tubular valve, provided with one or more openings near its upper end, inclosing a part of said chamber, by its positioncontrolling said ports, and a float attached to said valve'adapted to control its position.
3. A device of the kind described, comprising a shell provided with an inlet and an outlet opening, means for connecting said shell into a heating system, a chamber arranged within said she] inclosing saidoutlet opening, provided with ports formed through the side wall, and with an air vent through the end wallof said chamber, and having a recess 7 formed in said side wall extending around said chamber at the ports, in combination I with a" tubular valve provided with one or more openings near its upper end, inclosing a partof said chamber, by its position controlling said ports by covering said recess, and afloat attached to said. valve adapted to control its position.
4. A device of the kinddescribed, comprising the combination of a shell provided with an inlet and an outlet opening, means for connecting said shell into a heating system,
described, comprisports by coverin a chamber arranged within said shell in closing saidoutlet opening, and rovided with orts formed through the wa of said cham er, and with a recess formed in said wall extendin around said chamber at the ports, a tubu ar valve inclosing a art of said chamber, by its position controlling said ports by coverin said recess, a fioat attached to said va ve adapted to control its position, and a tubular screen arranged within the shell and partly inclosing said valve and, chamber.
5. A device of the kind described, comprising the combination of a shell provided with an inlet and an outlet opening, means for connecting said shell into a heating system,
