STEAM-HEATING AIEARATUS.

Specification of Letters Patent.

Pei/tented Apia 25, 191i Application filed August 4, 1910. Serial No. 575,473.

To all whom it may concern:

Be it known that we, lVILLIAM T. Peon United States, residing at Lynchburg, in

the county of Campbell, State of Virginia,

have invented certain new and useful linproveinents in Steam-Heating Appnratus; and we do hereby declare the following to bee full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steam. heating apparatus. l

The object of the invention is to provide a steam heating apparatus adapted tocontrol automatically the draft of the boiler and thereby secure a uniform steam pres sure and to enhance the efli'ciency of the s; stem with which it is associated.

ll ith the above and other objects in View the invention consists in the details of construction and in the arrangement and coinl'iination of parts as will be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail referencr will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several-views; and in which v Figure 1 is a side elevation of a boiler with the invention associated therewith;

Fig 51, an enlarged side elei 'ntion of the invent i; 3, a section on the line 3-3 of -n, and, Fig. 4, a section on he line ll g. 3, the reservoir being partly broken away.

l lorl'erring to the drawings, represents the boiler which may be of any desired form and which is provided with a check damper l1 and :1 draft door 12 located respectively at th smoke pipe or flue and at the bottom the boiler for controlling the draft through. the smoke pipe'or connection and through. the base of the boiler to the fire, and these dampers are controlled by means hereinafter described for maintaining a uni forn'i steam pressure throughout the system with which the boiler i0 is associzited.

"the pressure regulator is indicated generally by A and comprises a substantially elliptical casing provided with an upper opening 13 and a, lower opening 14. A pipe connection 15 has one end mounted in the opening 13 and its other end communicating with the atmosphere through the chimney Another pipe 17 has one end secured in the opening 14 and its other end communicating with the interior of the boiler 10 below the water line. From this construction it will be apparent. that as the pressure in the boiler 10 increases the water contained there in will be forced through the pipe 1Z'.into the casing or reservoir of the pressure regulater. ilournaled in the casing of the. reservoir is a'sliaft 18, one end of which. extends cxteriorly of the reservoir asat 19. l iXcd on the shaft 18 within the reservoir is an arm 20 which carries at its free end a fleet 21. Another arm 22 is also fixedly secured in termediate its ends to the exterior ortion of the shaft 18 and has one end terminating in a pointer 23. Also formed in the arm 22 on opposite sides of its connection with the shaft 18 are eyes 24 and 25 and a chain 26 has one end. connected in the eye 24 and its other end secured .to the check damper 11, while another chain 27 has one end secured in the eye 25 and its other end to the draft door 12; said chains traveling over-suitable pulleys 28 arranged above the boiler. litemovably mounted upon the outer face of the reservoir adjacentthe pointer is a dial plate 29 which has indicated thereon a scale of pressures, increasing from its bottom toward its top. 7

As water is forced by the pressure in the boiler into the reservoir it will be enparent that the float 21 will be elevated and the shaft 18 in consequence rotated. This foth tion of the shaft 18 will in turn cause u movement of the arm 22 and effect through the chain connections 26 and 27 the opening of the check draft 11 and the closingof the draft door 12 and thus decrease the pressure in the boiler- A reverse movement of the arm 22, due to the descent of the float. 21 will in. turn open the draft door 12 and close the cheek damper 11', thus raising the pressure within the. boiler. llnring; this movement of the nrinQZ the pointer 23 will at all times indicate in connection with the dial plate 29 the pressure existing within the boiler. In order to prevent the water forced into the reservoir from passing through the opening there is detachahly mounted in said opening tuhular bushing 30 while a second tubular bushing 31. is detaohably mounted within the bushing 30 end has the outer end of its bore threaded for connection with the pipe 15. Suspended from the lower end of the bushing 31iis a plurality of U-shaped wires 82 with their bent portions intersecting each other and disposed across the bore of the bushing 81. Seated upon the bent portion of the wires 32 is a hollow float valve 33, the lower end of which is open, while the upper end thereof is closed and. ot' conical formation. From this construction it will be apparent that when the water forced into the reservoir reaches the level of the float valve 83, the latter will be raised from its seat upon the bent portion of the wires 32 and elevated so as to close the opening through the bushing 31 and thereby prevent the passage of water through the pipe 15.

As the dial 29 is removable it will be apparent that the figures thereon can be changed and the reservoir placed at a higher or lower point and the pointer and dital will still indicate the higher or lower pressures.

What is claimed is:

In a steam heating apparatus, the combination of :1 boiler, a reservoir located above the water line of the boiler, having an upper openingventing to the atmosphere, and a lower opening in communication with the boiler below the water line, a bushing mounted in said upper opening, a plurality of U-shaped wires suspended from the lower end of said bushing and extending into the reservoir and having theirbent portions intersecting each other, a fioat valve seated upon the bent portion of said U-shaped wires and guided by the arms thereof during its movement to open and close the opening through the bushing, a float located within the reservoir, and a damper and a,

draft door said float.

' In testimony whereof, we afiix' our signatures in presence of two witnesses.
