Gonnected wlth t he lowest end-portion of the return-riser or pipe 17 is a T-fitting 19, from u 'whicl'i extends a pipe 20, which is suitably connected with the lower located rece ver or tank ortion of a suitable'receiver, tank or con enscr, as 21. A pipe 22, of a smaller cross-sectional area than the pipes 17 and 20, extends from the l fitting 19 andpasses into the upper portion of the receiver or tank, 21, said pipe 22 having a hand operated regulating-valve 23 therein, and terminating within said 21 in a downwardly extendring pipe-end 24;. Leading. from another part of the upper portion of said receiver or tank 21 is a pipe 25 in which there is'a hand operated; regulating-valve 26, said pipe beingconnected by means of a fitting 27 with a pipe 28 which is provided with a pair of -T-fittings 29 and 30.

Suitably connected with and extending from the T-fitting 29 is a pipe 41 which extends into the receiver or tank 21 at a desirable poinhbetween the lower inlet and upper outlet of said receiver or tank, substantially as illustrated. Located in said pipe is. a valve 42,c0nnected with a bracket 43 secured to the tank 21, said valve 42 having suitably connected with its valve-stem an actuating lever. or arms); This lever orarm is provided upon its end-portion with a link-shaped part or member 45 into which extends a pin or projection 46. formed upon the side of a rod 47 which is movably disposed in suitable guides 48 and 49, and is provided with suitable stops 50 and 51,
which may be adjustably arranged upon said rod and are adapted to limit the move- 'ments of said rod in either direction' Riding upon the surface of the water of condensation in said tank or receiver 21 is a1 float 52, from the opposite portions of which extend suitably shaped rods or arms, as 53 and 54:, respectivel provided at their free ends with suitably ormed eyes or embracing portions 55 which embrace'and are indcpendently movable upon said rod 47, so as to be brought in engagement with said stops 50 and 51, as the water rises or falls, to move the rod 47 in either direction, as the case may be, and by means of the lever or arm 44;,

Leading from the tank, receiver or con denser 34 is a pipe 56, said pipe extending from the interior of the tank or receiver at a point above the point of inlet between the pipe 33' and the said tank or receiver, the said pipe 56 being also connected by means of a as ,57, with apipe 58 leading to and deiver or tank 31.
tion-chainber of said stem tuatlng members or elements "which there isa valve 74 being Communicating with the suction-chamber (30 of a Suitable pump, as 59. In the said pipe 58 is a T-fitting 61, -a pipe-connection 32, in which there is a hand operated regulating valve 63,-being located between said litting- 623.1141 the upper interior of the said re- Extending from the sucpump is the usual outlet or discharge pipe (34. The referencecharacter (55 indicates the steam-cylinder of the pump, and (56 is the exhaust which is connected therewith. Intermediately disposed between the T-fitting 4 in the main pipe or line 1 and the inlet (57 of said steamcylinderbf is a steam-conveying pipe (38,- in which pipe are located several T-littings 69, 70 and 71, and a valve 72,- a pipe 73 in connected with the T-littings 70 and 71, so as toprovide a by-pass for the purposes to be presently more fully stated. Extending from the fitting which' communicates with the T-fitting (30 in the pipe (38 and is provided with a valve 70. Movably arranged within said receiver or tank 34, so as to ride upon the surface of the water of condensation in said receiver, or tank, is a float 77, said float being provided with avertical'stem-or rod 78 which extends through and is slidahly arranged in a guide 79 in the top of the said tank or receiver. Suitably connected with the said Mind 7 8 are a pair of valve-lever ac- 80 'and 81, preferably of the construction shown in Figs. 3 and l of the drawings, and consisting-0t linlnshaped devices, the sides 82 and 83 of which may be provided with holes or perforations 86 for the insertion of an en gaging pin, bolt or stud and one of the sides, as 82, being preferably. formed with an open portion 84 for the arrangement" between the sides of the member or element 8001 a Valve-spindle operating arm or lever adapted to'be detachably connected \Vllll the valve 72,01, for the arrangement bewithin said body is tween the sides or the other member or element 81 of a valvespi11dle operating arm or lever 88, adapted to he detarhably connected with the valve 70.
Referring nowto Fig. 2 of the drawings, it. will be seen that the radiator-valve 0, pre viously mentioned comprises a suitably formed main hollow or chambered body 89 provided with a suitable inlet 90 and an outlet 91. Rotatably disposed upon a seat 92 a valve-body or' element 93, which has a perforated top 94, but is open at the bottom, as at 95, so as to form a chamber 00. The purpose of this perforated top 04 is to permit sutiicie'nt fluid, as steam, to pass uponthe other side of said top, that the valve-body or element 93 will be balanced. In its side 97 the said valve-body or element 93 is made with an opening"98,
5 isanother pipe-connection adapted to be moved over the opening of the outlet 91, so as to provide a direct passageway for the heating medium entering at 00 into the chamber SH) and through the opening 08 and outlet 01 to the radiator, as will be clearly evident; but the parts being arranged so that said opening 98 is moved away from the outlet 01, so toclose the passageway for the steam to the radiator, Upon the upper closed top 94 of the said valvcbody or element 08 is an upwardly extending projection or lug 00 upon which is arranged a socket-lil e end-portion 101 of an operating stem 100 which is'provided at its upper end-portion with a suitably disposed operating handle 102. The. upper portion of the said main hollow or chambered body is formed with a screw-threaded part 105 upon which is screwed a suitably formed closing cap or bonnet 10 1. This cap or bonnet 101 is made with a suitable screwthreaded neck or openpart, as 105, through which the valve-stem 100 extends, as shown, and upon the upper portion of the said bonnet or cap 104 is a chambered member or bonnet 106 which is provided with an internally screw-threaded portion 107, so as to be adapted to be screwed upon the screwthreaded portion of the closing cap or bonnet 104. Upon its upper portion the said mcmher or bonnet 106 is made with a tubular part 108, through which the valve-stem extends and is rotatively arranged therein as shown. Suitably arranged within the chambered part of the closing cap or bonnet 100, resting directly upon a closing end-portion 109, forming a valve-seat, is a packing gasket 110, or a metal disk may be used, said disk'resting upon said portion which in that case is ground to provide a ground joint. The operating stem or spindle 100 is provided with a flange 111, resting directly upon said gasket or packing disk 110, a spring 112, which-is arranged within the chamber 113 and which encircles the said no spindle 100, in the manner shown, being used for pressing the annular flange 111 down upon .the said packing disk for retaining it in its operative position, as will. be clearly evident. If desired another; packing disk 11% may also be arranged, 'imthe manner shown in said Fig. 2 of the drawings, and held in the said position, as shown, by means of an annular oft-set 115 of the closing cap on bonnet 101, when the latter is screwed down upon the hollow or chambered body 89. In this manner I have provided a packless and quick-opening radiator valve, which at no time requires any packing and insures against the leakage of steam around the stem of the valve. The valve is quickopening, about one-quarter of a turn opening and closing the outlet 91, and it'have produced a simply constructed radiator-valve which is admirably adapted for 51158111 Vacuum steam heating systems, because there can be no leakage as with the ordinary packed radiator valves, which no matter'how carefully they are packed about the valvestem, will with constant use Wear away, and very often after a few operations a suficient leak will develop around the packed stem of the valve to make it impossible to hold the vacuum on that particular radiator.
Referring now more particularly to Figs.-
screwing the cap in place. Extending from the one side of the said tubular member 14 is an externally screw-threaded tubular portion or element121, which'is adapted to be connected with the pipe 13leading from the radiator 11, and forms asuitable inlet into the interior of the said. tubular body 14, as will be clearly understood. An angular valve-seat 122 may be provided, and arranged upon the said valve seanso as to close the same by means of its own weight, is a suitable valve-disk or plate 123, the said disk or plate'being provided with suitably formed ears or lugs 124, for arranging said ears or lugs over a pin or pintle 125 for operatively connecting the said valve-disk or plate to a perforated ear or lug 126, so that the valve disk or plate 123 Wlll be secured in its operative position in a hingelike manner.
ay be provided with a yoke-shaped member 1 7 withwhich is connected a stem. This stem 128 has pivotally connected therewith an upwardly extending rod 129 which has arranged thereon and has suitably secured thereto a counter-balancing disk 130 of sub-' stantially the same or of a slightly larger area than that of the valve-disk or plate 123, said disk 130 being suitably-fitted 1n the annular portion 131 of the tubular member 14, and being capable of a free slidable movement therein. The said valve-disk or plate 123 is provided with a small orifice or hole 132 which is covered by a small valve-disk or plate 133, normally held in its closed position by a spring 134, said parts being ar-' ranged substantially in the manner shown in said Fig. 5 of the drawings.
Having in the foregoing description set forth in a general way, one arrangement of devices and instrumentalities for producing a vacuumsteam-heating system embodying theprinciples of my present 1nvent1on, I will now brieflyset forth the method of its The said disk'or plate 123 operation. In practical use and assuming that it is desired to use steam at or below atmospher c pressure, the valve 74 is set so that it is only partially open, the valve 72 being closed and the valve-operating armor lever 87 being connected with the projecting 1 end of the valve-spindle and its end-portion being inserted between the sides of the device 80, in the manner shown. It will be well to mention here, that the other valveoperating arm or lever 88, however, is de-f tached from the projecting end of the spindle of the valve 76, because it is not desirable --to actuate the said valve 76, at this time.
When exhaust steam is used for heating purposes, the valve 3 in the pipe 1,' is closed and valve 2 is opened. The live steam enters through pipe 1 into the pipe 73-, and through the partially open valve 74 in said pipe 73, passing into the steam-cylinder 65 of the pump 59, and being exhausted at 66.
Owing to the partially open condition of v the valve 74 aslow movement of the pump is produced with the result that the air is drawn by suction from the radiator 11 into the pipe-connection 13 and the orifice 132 in the disk or plate 123 of the discharge or drainage valve 14, suitably lifting the small valve-disk or plate-133, the several regulating valves 23, 26, 36 and 63 being set so as to regulate the area of the passages in the pipes 22, 25, 31 and 62 in which the regulating valves are placed. The air is thereupon sucked through the pipes 15, 17, 22 and 24 into the receiver or tank 21, andfrom said receiver or tank 21, through thepipes 25, 28, 31, 35 and 37'into the receiver or tank 34; From within this receiver or tank 34 air is sucked into and through the pipe 62 and part of the pipe 58 into the suction chamber 60 of the pump 59, being finally expelled through the discharge pipe 64. At the same time, the small orifice 132 is such that a- .smaller vacuum is produced in the radiator thanv in the vertical return-risers, the area of the disk 130 being practically the same as that of the valve-disk or'plate 123 *SE) that any action of the disk or p ate 12 3 swinging open is counteracted by the counterbalancing disk 130. The arrangement of the cap 119 upon the upper portion of the valvecasing 14 is such that it does not fit tight, whereby some air is permitted to. enter the valve-casing above the counterbalancing disk 130, and thus aids in causing said disk to ing of whichthe pipes ;40,and 38 are art, The radiator-valved)! having also een opened, exhauststeam enters from the pipe 7 through the pipe-connections 8 and 10 into the radiator 11, for heating purposes. A
vacuum having ,thus been produced, the
valves 23, the Water that may wile the cold body ofivuter, always in the tanli, being immediately condensed into water.
ordinary amount of Water of cndiators 1.1,llovvs-l7hrough the orilice from the pipe-connection l3, and thence through the pipes 15, l? and into the bot tom of the receiver or tank 21, located at the bottom of thereturn-riser. The rising Water in each receiver or tank 21 finally floats the float 52, so as to cause the same to move upward, at the same time, sealing the inlet to pi ac The upward movement of brings the arm 53) against the stop so, v-rhcreby the rod or stem i? is also moved in upward direction, so that the valveopesating arm or lever ii is operated so to open the valve 42. The water then.
flows from said receiver or tank '21, into and throng the pipes ll, 28, 31, and into the bottomof the main receiver or, tank 34, Where the Water of condensation is collected. In like manner, all other water of condensatiou coming through the pipe all passes through the pipes 38, 31 and 33 into the bottom of the tank or receiver 681' in said tank or receiver 3% 1 ,s, lifts the float i'fZ, and produces an upward movement of the stem or red 78, and the" device 80 connected with said sterner red, the water at the same time sealing the inlet end of the pipe 3?. The upward movement of the said device 80, by means of the pin, stud, o the, like, 85, being brought in lifting-enement with the end of the valve-operatui armor lever 87, movesthe latter and opens wide the valve 72. A full supply of live steam, from the pipe 1, is thereby permitted to" enter the steanrchamber or cylinder of the pump, through the pipe 68, so as to cause the rapid working of the latter. The result will be that the excessive collection of Water of condensation in the tanks or receivers 34: and 21, will hepumped lherefrom, and will be exhausted at the pumptlirouuh the outlet pipe 6i, us will be clearly understood. The lowering levels of tliic different bodies of Water, in the receivers or tanks 34 and 21, produce a lowered-con dition of the flow so that'lhe valve 72 is ugntin closed and the valve 42 is also closed, thus bringing the entire systen'i once more down to its normal condition, for the repetilion of the various steps in the method or process l'zcreinabove described.
in case of a large supply of water of condensation in the radiator, at such time after the valve 1) has been kept clowl, or that may 'on resulting in the radiator or ra-' is the W:L-'
have collected in the pipe connections between the radiator and the d ainugc valve l l, when the pump is rapidly set in operation, the increased supply of Water lifts the said disk or valve or plate 123k) such a dcg'rcc, that the water of condensation is suddenly removed, in the same manner as above described. In case the exhaust from the steam-engine or other source of supply is insufficient to properly heat the radiators, it may be desired to periodically admit live steam into the radiators. To do this the valve-operating lever or arm 88 is now con nected with the end of the valve-spindle of the valve 7 the end-portion of the lover or arm 88 being arranged between the sides of the device 81, so as to rest upon the pin or stud S5 of said device. The upward movement of the rod or stem 78, also moves said device 81 in an upward direction, so that the valve 76 is opened, whereby live steam from the pipes l and 68 enters the pipe and then passes into the riser l8 and through the pipes 8 and 10 and the valve 9 into the radiators, in addition to the sup ly of exhaust steam, as will be clearly understood. The lowering of the Water-level in the receiver or tank 34 again produces the closed condition of the valve 76', so that only exhaust steam is admitted to the radiators. The arm or lever 88 can thereupon be again disconnected, or left its connected relatimi, so that the valve 76 will be intermittently opened and closed, so that live steam will be periodically admitted into the radiators, if found desirable. By also opening the valve 3 live steamcan be directly admitted into the risers and radiators from the main steam-pipe l, in the case that it is necessary to make repairs to the other parts of the system, or otherwise.
From the foregoing description of my present invention it Wlll be seen that l have devised a simply constructed and eiliciently operating steam-heating system or apparatus in which the vacuum-p oducing source is automatically controlled by the water of con-. densation, so as to maintam a vacuum in the radiators and keep them free from the Water of condensation, the general arrangement andconstruction of the parts being such that all the noises due to hammering are fully overcome.
