COMBINATION HEATING APPARATUS.

Application filed January 7, 1926.

My invention relates to improvements in heating apparatus, and the object .of my improvement is to eiiect a combination system for heating by means of hot water directly and steam indirectly, the steam being utilized for heating the water, and provision being made 'for regulation of the steamdelivery, the regulating means being directly actuated by the heated water.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, it being` understood that changes in the precise embodiment oi? invention herein disclosed can be made within the scope of what is claimed without dcpartingfrom the spirit of the invention.

In said drawings, Fig. 1 is a vertical longitudinal medial section of a heating radiator of the built up sectional type for heating directly by means of hot water, the view being diagrammatic, with parts broken away, and Fig. 2 is a like section, but showing a modification in the steam regulating means, which are illustrated in detail, 'fragmentarily, with other parts removed.

The radiator is built up of connected hollow sections 1 of a well-known type, having sleeve connections 2 above and below to permit circulation of water therethrough. One of these sections may be supplied with water at the top by a pipe 3 which may communicate with any source of water supply or with an expansion tank 4 located above the radiator.

The numeral 5 denotes a steam outlet pipe which centrally traverses the row of lower sleeves 2 and clamping screw plugs fitted in threaded seats in the end sections 1. This pipe 5 is in a steam circuit of piping to and from a source of steam under pressure, and at one end o the radiator includes a valve-chamber 6 in the communications, between said pipe 5 and an inlet pipe 7.

This valve-chamber and its regulating valve may be of any desired kind, other than that shown. The one illustrated comprises within said chamber 6 a closed hollow body 8 threaded upon the end of the pipe 5 and having a flat top provided with a beveled valve-seat 9 to receive and fit a beveled valvehead 10 adjustably mounted upon threads on the lower end of a vertical valve-rod 12 which traverses slidably a stuffing-box 11.

The numeral 21 denotes an elongated rod Serial No. 79,778.

preferably ot aluminum or other metal which possesses a high degree of coeiiciency of expansion, and which has a rigid bracket connection at one, its inner end, to and within one of the upper sleeves 2, it being understood that this sleeve is rigidly mounted in its seat, so that it becomes an abutment for this end oi the rod.

The other end oi' the rod 21 is passed through a stui'ling-box 2O outwardly and projecting into a casing 13 which is bracketed to the upper end ot the outer section 1. This casing has a downturned open end 111 into which extends the upper end of the valverod 12. A bell-crank lever 15 has one end pivoted at 19 to the outer end of the rod 21, is fulcrumed near said pivot on a cross-pintle 18, and has its longer member provided with a short slot 17 to receive a pin 16 projecting from the valve-rod 12.

rllhe valve-head 1() is to be adjusted upon the rod 12 so that it is spaced a proper distance above the valve-seat 9 when the water in the radiator sections 1 is cool. Steam then passing said valve-seat through the pipe 5 heats the water in the radiator in which it is immersed through conduction through the pipe but there is no communication between the pipe 5 and the interior water-containing space of the radiator. As the water becomes thus heated, the rod 21 gradually lengthens until a desired maximum temperature thereof is arrived at, by which time the valvehead 10 has nearly if not quite closed the valve-seat 9. The gradual contraction oit' the steam passage by way of said valve in shutting ott the steam proportionally, correspondingly lowers the temperature of the water, or rather, tends to bring the temperature of the water in the radiator to the critical degree, whereby an even temperature is automatically maintained.

In this device the regulator shown in Fig. 1 is actuated by the heat extension of the rod 21, but in the modification illustrated in Fig. 2, a regulating device of a similar mechanically moving type is used, the expansion of heated water in the radiator serving as the motive agent. In this installation, no eX- pansion tank 4 is used, as the water should be confined within the radiator closely, although any kind ot well-known resilientlycontrolled safety-release may be inserted in the radiator to eject water when compression has passed above a critical amount.

As Lthe water, however, is lusually not `to be heated foyer a .unoilerate temperature, an open-end cylinder of a proper capacity Vis placed in communication With the upper part of 'the radiator and detachably secured thereto and contains a flexibly packed imperforate piston 25, the latter ,having ,a -stein 23 slidably traversing the apertured closed end of the cylinder andalso a Ystuiiing-bou 2O to enter a bracketed hollow casing 24 which iclosed :at its outer :end iby '.a removable plug. iFhe .casing 12a `ihas lvertically alined apertures .near its outer end through which is ipassed Athe .upper :part of. the ualwerod 112 to project thereabove with .a .threaded .end

Y 28 ica-rrying a 4compresSion-:nut 27. Acoiled compression-spring .26 is .engaged between the top of' said casing land said nut 27'., :and the latter may .place the spring Vunder .an adjustable =.coinpreesion.

vits .the .radiator Water .is :heated Iit expands, and pushes the pistonl2`5 into `said cylinder, to :cause .its fstem to ,rock `the bell-orank `lever 1:5 .to lower .the rv'alv-e-.rod l2, .thus 'causing the ualveehead ito .control vthe steam .passn ing through the valve-.seat 9, in like =inanner to the irstamention@d :regulating device.

It Will be .understood that in this manner all :the radiator-fs assembled in a building' may be `automatically controlled, Aand independently regulated, and thatthe itwo means described :for iactuating the regulating .de-

vice, .as Welles othersef Lthe,eenera,.are in* dluded 4iin liny invention, ithe gist oi which is the regulation of the steam pressure by the Water condition automatically.

This 'invention thus confers upon the user the -benefit of Water heating of an evenly maintained desi-red maximum temperature, While using an easily generated steam supply dior itfhe heating agent, more responsive and economical than more complicated kinds ont heating apparatus.

Having described my invention, what l claim :as .nenv, :and 'desire to secure by 'Letters Patent, is:

A combination heating ,appauatua coinprisingza waterfcontaining radiator, a Water containing supply reservoir zabove, iin iconaniunication with :said :radiatomfoesupply ,Water thereto under head and to ralso .fsersve as fan expansion .receiver for YWater heated in zthe "radiator, a valve-'controlledsteam :com duit :in said radiator, :an operating .element also in said .radiatorfspaeed :from said con duit .-and responsive tto l.the temperature of the water, and `operating (connections :between l:and moved by saiid :element `when so influenced to faot-uate the )Stettin-conduit val-ve to .regulate steamapassagfe `and ithe heating oit .the 'water in fthe radiator.
