CLARENCE R. SHAW, 0F MARENE CITY, MICHIGAN.
Specication of Letters Patent.
Patented dan. 11, 19116 Application filed March 13, 1915. Serial No. 14,270.
To all whom it may concern.'
Be it known that I, CLARENCE R. SHAW, a citizen of the United States, residing at Marine City, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification, reference being had to the accompanying drawings..
'lhis invention relates to certain improvements in heating systems and has relation more particularly to a steam vacuumheating system and it is an object of the invention to provide a system of this general character having novel and improved means whereby after radiation, the air line is automatically sealed.
lt is also an object of the invention to provide a system of this general character having novel and improved means whereby the air line is automatically sealed upon the lowering of the steam pressure whereby air is prevented from rentering the system.
lt is also an object of my invention to provide a novel and improved system of this general character including a condensation tank provided with means whereby said condensation may be automatically returned to the boiler and whereby the system-is effectively sealed during the period such condensation is being returned. y
lt is also a further object of my invention to provide an improved system of this general character including a condensation tank which may be readily removed or taken down, without effecting the operation of the system.
My invention also contemplates the use of novel and improved air controlled means adapted to coact with a radiator.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved heating system, wherebv certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantaarranged in accordance with an embodimentof my invention, the condensation tank and its concomitant parts being shown on an enlarged scale and partly in elevation and partly in section.
As disclosed in the accompanying drawings, B denotes a boiler of conventional conL struction, it a radiator, S a steam pipe and Pf a return pipe, said return pipe having in connection therewith a condensation tank T positioned at a point at least twelve inches above the water line of the boiler and through which substantially all of the water of condensation is adapted to flow.
Tank T, as herein embodied is of elongated shape, having one end extremity in communication with the return pipe P through the medium of the branch pipe 1, having interposed therein a conventional gate valve 2, the return pipe P, at a point intermediate its communication with the branch pipe 1 and with the boiler being provided with the spaced conventional globe valves 3 and 4 and having interposed therein at a predetermined point between the valves 3 and 4, the check valve 5, whereby upward pressure through the return pipe, is prevented.
Telescopicallv engaged with the branch pipe 1 and projecting through a head of the tank T is an extension 6 of the casing 7 positioned within the tank, said casing having mounted therein the valve 8 adapted to coact with the adjacent extremity of the branch l for sealing the same. rihe outer extremity of the extension 6 is provided with the stuillng box 9 whereby a sealed connection is assured between the branch 1 and the extension 6 and in order to maintain the extension 6 against movement independently of the branch l., l find it of advantage to dispose therethrough the set screw 10 adapted to clampingly engage the branch 1. i also find it of advantage to have coacting with the extension 2 a conventional iam nut 11 coacting with the outer face of jacent the opposite extremity thereof.
Positioned within the well 15 is a ioat 16 adapted to engage beneath an extremity of the rod 17 fixed to a bell lever 18 pivotally mounted, as'at 19, Within the tank T and having one extremity operatively engaged with the endwise movable rod 2O for the .valve 8 whereby it will be perceived that up- Abranch 1 will determine the extent of upward movement required and the float 16 causing the valve 8 to assume a closed position.
In communication with the tank T at a point above the-well 15 is the relief valve 21 m communication with the atmosphere, said valve including the seats 22 and 23, the uppermost seat 22 having coacting therewith the ball valve 24 while the lower valve seat 23 has coacting therewith the valve member 25 xed to the stem 26 adapted for vertical movement and projecting within the valve 21, the upper extremity of the stem 26 being arranged for contact with the valve 24 for unseating the same upon up ward movement of the stem and at a predetermined period before the valve 25 operatively engages the lower valve seat 23. The lower extremity of the stem has mounted thereon a grooved wheel 27 operatively engagin the spring track-way 28 carried by the oat 16 and serving to compensate for any deficiency in the event the valves 8 and 25 should not work in strict accord As is believed to be self-evident, condensation is collected within the Vwell 15 which results in the elevation of the fioat 16 whereupon the valve 24v is unseated and permits ingress within the tank T of atmospheric pressure to cause the condensation to be automatically discharged through the Siphon 29 carried by the removable head 30 of the\ tank T and having its inner extremity terminating adjacent the bottom of the well V15 and with its opposite extremity in communication with the branch return pipe 31 v extending below the tank 1 and in suitable communication with the return pipe P, whereby it will be perceived that such condensation will be returned to the boiler B.
As hereinbefore stated, the upward movement of the float 16 will cause the valve 8 to seat against the adjacent extremity of the 4 branch pipe 1 and thus seal the system a ainst steam pressure so that the atmosp eric pressure will be sufiicient to force the water of condensation through the sipho 29 and pipe 31.
in communication with the branch return pipe 31 and the Well 15 is an equalizing y pipe 32 and interposed within the branch return pipe 31 at a point intermediate the equalizing pipe 32 and the Siphon 30 is the check valve 33 which serves to prevent retrograde flow through the siphon. also find it of advantage to interpose in the equalizing pip'e 32 a conventional globe valve 3i. 'lhe well 15 has also in communication therewith and depending therefrom the pet cock 35 of any ordinary or preferred construction. A
In communication with the radiator R at the conventional point thereon is the controlling valve V in communication withthe return pipe P through the branch pipe 36. F rom the foregoing description, it is thought to be obvious that a heating system constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible o some change and modification, without material departure from the principles and spirit thereof and for this reason l do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.
