Be it known that I, LEWIS CniivnN Olin, of the city of Montreal, Province of lQuebec, Canada, have invented certain neilv and uset'ul Improvements in Means for Regulating Steam-Ivleating Systems; and do hereby declare that the following is a full, clear, and exact description of the saine. y y

This invention relates more particularly to controlling devices adapted to regulate the .heating capacity of a steam radiator by controlling the escape of the Water of condensation therefrom land it has for an object to provide andimproved 'form' oi controller which will be simple in construction and 0I" comparatively small expense to manufacture.

Another object is to provide a construc-l tion for a controller Which Will permit ot' the How of steam thei'etlirougliI being shut oit7 at desired times and the `full fi'ovv of steam sent through the radiator.

F or further comprehension of the invention and of the objects and advantages thereof reference Will be had to the following description and appended claims, and to the accompanying drawings forming a part of this speciiication in which similar reference characters indicato the same parts and wherein'- Figure 1 is a side elevation of a railway car heater having my invention applied thereto; Fig. 2 is a plan vien47 thereof,";L Fig. 3 is a detail vertical sectional vieT of my improved regulator; Figs. et; 5 and 6 are horizontal sectional vieivs taken respectively on the lines 4e et, 5 and G 6 of Fig. 3 and looking in the directions indicated by the arrows, Fig". 5 being on a slightly larger scale than Figs. e' and G; and Fig. 7 is a detail tace view of the indicator plate.

in the drawings my invention is illustra'ted applied to the heating of a Water system, such for instance as is suitable for car heating, a steam radiator being indicated at A; ivhile a Water jacket for containing tlie Water to be'phea'ted is s hoivn at B and the iioiv and return pipes of the hot Water system at C and D respectively, these parts being of any approved constructioii, it being understood of course, thatthe ap'- plication of my inventionv is .not limited to a radiator employed for the particulail p'urpose here indicated;

My improved regulator comprises a stand pipe 2 screwed at its lower end into a casting 3 forming a valve casing the loi'ver end of which is bored and tapped to receive a plug 4 having a central passage 5 leading therethrough from top to bottom, the upper end of the passage being outiwirdly7 lia-red as at 6 to form a valve seat, the lower end o1" the passage being enlarged and tapped to receive the upper end of the usual ivaste pipe 8 Which is screwed therein, the Waste pipe leading to a thermostatic trap Y of usual censtrtictio'n and to which detail reference docs not .iieed to be made. The sido ivall of the valve casing has a tapped opening or port 9' into ivhi'ch is scr'eived the end of the pipe 10 leading from the lower end of the radiator, the upper end of the stand pipe being scr'eived into a head 11 which has in its side Wall a tapped opening or port 12 into which is screwed the end of a branch steam pipe 18 leading from the main steam supply pipe 14 Which connects to the upper end of the radiator in the usual manner, the pipe 14 being here shown as provided with a valve 13 located at a point between the branch pipe 13 and tlle radiator.

Located centrally Within the stand pipe and extending from top' to bottom thereof is a tube composed of a number of sections, there being three of thesesections 15, 1G' and 17 respectively here shown, this tube controlling the communication between the port 9 and the outlet passage 5 to the Waste pipe by adjustment of the tube as a Whole and oi tlie sections relatively to one another. As here shown these sections have screwed on the lower endsythereot sleevesl 20, 21 and 22 respectively, ivhose bottom' faces are beveled to form valves and 22, the valve 22 on the loiver section being adapted to seat at times uponl the before inentioned seat 6, ivh'ile the valves and vil are adapted to' seat at times ofi seats' 16 and 17 formed on' the adjacent upper ends of the sections 1G and 17. AThese sections connected to one another in a iiianner to permit both of limited relative movement thereof and of the ivhole tube being raised or lowered in the stand pipe to ,openi or close` the valves 20", 21 and 22 and so vary the level at which the Water of condensation may escape from' the stand pipe to' the outlet passage 5 as will be presently pointed out. As here shown these sections are connected one to another by coupling rings 2li and 25 screwed upon the lower ends of the sleeves 2O and 21 and having inturned annular flanges 24 and 25 engaging under circumferential flanges on the tops of the sections 16 and 17 and loosely encircling such sections, these coupling rings being of sufficient length to allow of movement of the valves 20 and 21 the coupling rings being formed with openings or parts 2G and Q7 respectively coni- 1nunicating with 'he spaces between such valves and seats when the valves are open while the section 15 is provided with openings or port-s 2S near its upper end. The sectional tube is centered within the stand pipe by means of circumferential flanges 29 cast on the sleeves 20, 21 and 22 and provided with vertical ports 30 to permit of the passage of the water of condensation or steam.

Screwed upon the upper end of the section 15 is a cap 32 whose top is formed to present a valve 33 adapted to register with a downwardly facing seat 34 on a ring 35 screwed into the top of the stand pipe, this valve controlling admission of the steam from the branch pipe 123 to the stand pipe as will be readily seen by referring to Fig. 3.

Formed integrally with the cap 32 and extending upwardly therefrom is a stein 37 which projects through a plug 38 screwed into the top of the head 11, there being a screw thread connection 39 between the stem and plug so as to cause rotation of the stem to move it vertically, a packing gland l() preventing escape of the steam. rllhe pitch of the thread 39 is preferably such as to cause the stein to move vertically at each complete revolution, a distance equal to the amount of lost motion between each of the sections. Mounted upon the upper end of the stem is a handle 111 having a downturned indicating finger or pointer 4t2 adapted to register with different ones (according to the heightof water to be maintained) of a series of indentations 423, or other suitable marks, on a segmental plate ll secured as by screws l5 to the head 11. These indentatio-ns may be designated Full, -1- and -land show, according to which one the pointer registers with, whether the controlling tube is adjusted t-o cause the water of condensation to escape directly to the waste pipe under valve Q2, or through respective ones of the openings 26, 27, 2S.

Operation: if only a small portion of the heating surface of the radiator is to be utilized the handle'lll is turned until the indicator points to l; in which posit-ion the valves 20', 21 and 22 will all be seated upon the respective seats, closing all communication between the stand pipe and outlet passage except through the openings iu the top section and consequently causing the cator points to -1- in which position the valve 20 will be lifted from its seat by reason of the loose connection between the sections of the tube and the water of condensation will escape through the openings 26, the valves 21 and 22 being still held closed by the weight of the sections 1G and 17, while a further movement of the handle will cause the section 1G to be lifted and the valve Q1 to be raised and the water of condensation to escape through the openings 27.' Any slight leakage that may taire place through the valves due to the fact of the valves being held in place only by the weight of the tube sections will not be sufficient to affect the proper working of the device because of the continuous supply of the water of condensation from the radiator, while it will be obvious that with the water of condensation at the highest level the handle can be turned to force the sections firmly down upon one another and tightly close the valves. To cause the full heating surface of the radiator to be utilized the handle is turned farther until the indicator points to Full, in which position the valve 22 is lifted from its seat, (the whole tube being suspended in the standpipe) and the water of condensation flows directly to the waste pipe, the valve 38 preferably seating on its seat and shutting off the steam from the controller when the full heating surface of the radiator is being utilized.

r1`he construction permitting the steam being shuto fromthe regulator when the full heating surface of the radiator is to be utilized has been found to be very desirable becauseof the liability to a more rapid condensation of the steam in the radiator than in the controller resulting in a higher pressure in the controller than in the radiator with a consequent tendency of the back pressure from the controller through the pipe 10 to prevent the escape of the water of condensation and cause it to back up in the radiator. p

To prevent any chance of the radiator freezing in very cold weather the handle Y of valve 13 may be removed (with the valve open) thus rendering it impossible to completely shut off the radiator as the portion thereof above the openings 28 will always be open to the steam supply. 1n milder weather the valve handle can be replacedk and the steam supply to the radiator shut ott, while at the same time a passage to the steam trap through the regulator will be lett open thus protecting the thermostatic trap from freezing, to which it might be liable because of its exposed position.
