MARTIN HANSON, OF ST. PAUL, MINNESOTA.
AUTOMATIC DRAIN VALVE.
Application filed May 1,
T all whom it mayco'nce'rn:
freezing waterf -The device is applicable to the water' Be'it'known, that I; MARTIN HANSON, a citizen of the United States, residing at St. Paul, in the county of Ramsey and tate of Minnesota, have invented a new and useful Automatic Drain Valve, of which the following is a specification.
My invention relates to automatic outlet valves for water containers in danger of freezing and the object is to prevent damage to the container'by the expansion of the jackets of explosive engines and to any other water vessel or container liable to be ex posed to frost. I
In the accompanying drawing:
Fig. 1 is a vertical section through a portion of a water container and my device 7 applied thereto.
Fig. 2 is an enlarged section on line 2-2 in Fig 1.
Fig. 3 is a vertical section of a portion of an explosive engine clyinder and. its water jacket, the latter provided with my device.
Referringto the drawing by reference numerals, 5 designates the water holding vessel or container; which may be either open or closed at the top. In the bottom (5 of it is threaded at 7 a vertical tubular body S having an'intcrnal circular recess 9.
Slidable in said body is a sleeve 10 having" near its middle radial apertures 11 through which proje :t into the recess 9 the catches12 formed at the ends of the legs of aresilient arched spider 1'3. 7
leis a screw to limit the downward movement of sleeve 10 when a foot valve 15 suspended from sleeve 10 by a suitab e hanger 16 is suitably lowered as shown in dotted lines 15 in Fig.1.
Slidablc in theupper portion of sleeve 10 is an actuator tube 17 whose middle portion is tapering and provided with one or more water ports 18. Above saidport the reduced portion of the tube has inserted in it a plug 19 preferably made of hard rubber, and in the plug is secured a standing bolt 20 upon the upper end of which is secured by a nut 21 a soft rubberivalve 22 which fits water tight in a valve in the upper end of tube 8. I
In operative position the valve 22 is normally closed to retain the water and valve 15 normally closed to keep cold air out seat 23 1922. Serial No. 557,735.
of the tube 8. When the water 24 00111- Inences to freeze and is thereby expanded, it presses the valve 22 down as in the dotted lines 22 in Fig. 1, thereby causing the actuator tube 17 to press the spider'legs inward and thus disengage the catches 12 from recess 9 and letting sleeve 10 drop down on screw 14 and opening valve 15. The water is new free to run out and leave the container empty enough SO'lt cannot be dam aged by freezing of any waterleft in it. When the danger of frost is past the valve or plate-15 is simply pushed upward to closed position. This will also close valve 22, and the water container may be refilled. It is understood that the outward spreading tension of the spider issuii icient to support the actuator tube and valve 22 as long as the latter carries only the pressure of the water upon it. but it yields to the extra pressure caused by freezing of the water.
In Fig. 3 25 designates a. portion of an engine cylinder having; the water jacket 5 for cooling the cylinder.
\Vhat I claim is:
'1. l he combination with the lower part of a water container oi 'a. vertically disposed water outlet. tube depending therefrom and having: in its upper end a valve seat and a vertically movable valve therein. and an internal circular recess iartluir down in the tube, a sleeve slidable in the tube and having radial apertures. a res lient arched spider in the sleeve with its legs normally projecting through the apertures and into the circular recess. a laterally perforated actuator tube suspended "rom the valve and having its lower end supported on the legs of the spider so as to press them together and therebi disen: 'e them From the. ircular recess when the top of the valve is subjected to a n'eiilctcru ined degree oi pressure.
2. The structure specified in claim '1. and means limiting the dmvnward movement of said sleeve.
3. The structure specified in claim 1. and a second valve suspended from the sleeve and arranged to close the lower end of: the
outlet tube when the first mentioned valve closes the unner end of it.
4. The structure specified inclaim 3, and means for automatically supporting both valves when they are open.
In testimony whereof I afiix my sign ature. MARTIN HANSON.
