HEATING DEVICE.

To all whom. it may concern Be it known that I, WILLIAM F. SHAUGH- messy, a citizen of the United States, and a resident of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Heating Devices, of which the following is a specification.

My invention relates to heating systems and has for its primary object to provide a construction characterized by superior simplicity and efiiciency and having a capacity for perfect regulation within limits that can be adjusted at will to meet the requirements of every possible range of conditions that may arise in practice.

A further object of my invention is to provide a heating device in which the heat is stored and radiated by one medium and supplied by another; the latter medium or agent being preferably non-combustible in its nature and being supplied to the heating device in such a way that its admission thereto is controlled by the thermal condition of the first medium; the expansion of the radiating medium serving to restrict the admission of the heating agent until the latter is shut olf entirely.

Still another object of my invention is to provide the heating device with manually operable means whereby the point at which the expansion of the radiating medium acts to shut off the heating agent can be adjusted to suit convenience or necessity; whereby perfect regulation within any desired limits can be obtained.

A preferred embodiment of my invention is illustrated on the accompanying drawings, wherein the same characters of reference are employed to indicate the same parts throughout the several views.

On said drawings Figure 1 is a side elevation of a heating device or radiator with a regulator attached in accordance with my invention; Fig. 9. is a longitudinal section of a detail of my construction; and Fig. 3 is a similar view of one form of regulator which I employ in the practice of my in vention.

Referring particularly to the drawings, I utilize a radiator 1, supported by feet 2, this radiator being hollow to receive a suitable heat-radiating medium such as water. Within the radiator 1 and preferably at the bottom of the same I locate a hollow body or cylinder at, to which the agent which im- Specification of Letters Patent.

parts heat to the water is supplied. The admission of this agent to the interior of the body 4 is regulated by suitable automatic mechanism shown at 5, this mechanism comprising a casing communicating with the casing formed by the radiator 1 and having therein a piston 6 connected by a rod 7 to a valve 8. This valve is located in a pipe or conduit 3, which will be an ordinary steampipe when steam is used. A suitable casing 9 may be employed to house the valve 8, and this casing will be connected to the pipe 3 on the one side and the cylinder t on the other, as will be readily perceived.

The radiator may be constructed of any number of sections 10, having air spaces 11 for circulation of the air in the room or apartment containing the radiator, and thus give a greater heating eifect. The water may be supplied thereto from a pipe 12, which may be connected to a suitable water source; the pipe 12 being united by a branch 13 to a T 15, from which a section 16 leads directly into the radiator. A valve or cook 14: may be inserted in the branch 13, to turn on the water and shut it off at will. Likewise a suitable drainpipe 17 having a valve 18 will be provided. As shown on Fig. 1 the water will enter the casing of the radiator at the top and be drawn off at the bottom, and this arrangement permits of the flushing out of the radiator, so that the same can easily be cleaned without taking it apart or dismantling it. The pipe 12 may be run into every room of the building, and a common branch may be used to unite the pipes 18 to conduct the drain water to the sewer. The casing 5 is connected to the T 15 by a short section of piping 19, so as to allow the water in the radiator to enter the casing 5, as will be fully described later.

The section 19 may be joined to the casing 5 by any suitable coupling. I have shown on the drawings a bushing 20, having a flange 21. This flange is engaged by a hollow threaded nut 22, which screws upon a threaded boss 23 of the casing 5. The bushing is internally threaded and the lower end of the section screws into the same.

In the casing 5 I locate the piston 6 above mentioned, this piston being cup-shaped and inverted, and being surrounded by a suitable packing. The rim 24: of the piston is turned outward, and to the piston is secured a ring 25, between which and the rim the packing 26 is held. The piston rod 7 is secured to the piston preferably by nuts 27, and a suitable spring or other yielding body 28 may be placed between the spring and the bottom of the casing to prevent the too easy movement of the piston 6.

I prefer to make the rod 7 in two sections, the lower being hollow and receiving the upper in screw-threaded engagement, so that the total operative length of the rod can be increased or diminished to suit the degree of regulation aimed at. The lower of the rod sections will have a collar 32 thereon, and the upper will be received in a sleeve having screw-threaded engagement with a boss 29 in the bottom of the casing 5. This sleeve 30 will have a handwheel 31 thereon to facilitate turning the same, and it will engage the collar From this it will be perceived that by turning the sleeve to move it toward the casing 9 the valve 8 can be closed entirely, or the extent to which the spring 28 may open the valve altered at will.

The lower section of the rod 7 enters the valve case through a gland or stuffing box 33, and the casing 9 unites with the steampipe by means of a threaded boss 34 and unites by means of a similar boss 35 with a section 37 leading into the body 4. A suitable nut or packing 36 may be used to make a tight joint bet-ween the boss 35 and the section 37. This nut or packing may also be used to unite the casing 9 and pipe 3. It will be internally threaded to receive either the boss 3st or 35, and the adjacent threaded end of pipe 3 or section 37. Obviously any convenient form of joint for these parts of my construction may be employed, and suitable washers inserted to make the same proof against leakage.

In order to secure the body or cylinder a in place inside the radiator 1 I mount the cylinder in a special form of nut which not only serves as a support for the cylinder but also acts at the same time as a cap or closure member for the aperture in the radiator 1 through which the cylinder is admitted. This nut is shown at 38, and it is provided on one side, the inner side, as will appear from inspection of Fig. 2, with an annular rib 39, that is threaded both inside and out. Into this rib the cylinder is screwed, having its end 40 threaded for this purpose. The other end of the cylinder is closed, and the cylinder and cap form a closed chamber for receiving the steam or other agent adapted to impart heat to the water or other radiating medium in the radiator 1. The threads on the outside of the rib 39 enable the nut to be screwed into the opening in the radiator through which the cylinder is inserted, and when screwed home the cap completely closes this opening. The cap or closure member'38 also has a threaded opening to receive the pipe 37, shown at &l; and is further provided with a threaded port 42 to receive a tube 43, the function of which will be presently set forth. This port 42 leads to a passage a l in the body of the cap 38 which runs to a valve Q5 secured to the cap in a threaded opening 4:6. This valve serves as a vent or blow-off for the cylinder at, and may be of well known type. It is sufiicient to say here that the vent valve &5 is so constructed that it will allow air to escape from the cylinder f as soon as the steam is turned on and enters the cylinder, but as soon as the steam reaches the valve d5, the same will close automatically and orevent the escape of the heating agent. N ien the steam is turned off, and the chamber cools again, the vent valve will open and allow air to enter the cylinder to relieve the vacuum caused by the condensation therein.

It will be observed from Fig. 2 that I place the opening 41 in the cap 38 so that it will communicate with the lowest part of the cylinder at, and locate the opening 42 so that it will communicate with the highest part of the cylinder. I thus facilitate the draining of the water of condensation back into the steam line where it is taken care of by the traps, and at the same time I am enabled to put the tube 43 so high above the lowest part of the cylinder 4:, that should there be any water by any mischance in the cylinder 4 when the steam is turned on, the level thereof will never reach the tube. Hence none of it will be blown out through the vent valve 45 and all spitting and sputtering at this valve, with the consequent soiling of adjacent objects will be entirely eliminated. I consider this an important advantage, and the nut 38 is a quite important detail of my construction.

From the above description the operation of my heating device will be readily understood. lVater is admitted to the radiator to fill the same, and the level of the liquid therein can be read by means of an ordinary gage 011 the radiator 1 near the top. The radiator 1 will be filled, and I may provide a vent for the air which may afterward be closed. Of course all the air need not be exhausted, since some space may be required to allow the water to expand to a certain degree before it actually moves the pis ton 6. Some of the water entering the radiator may be allowed to flow directly into the regulator casing, but I may close this casing by means of a valve in the pipe 19 at this time if desired. After the radiator is filled the steam can be turned on and when the water has expanded to the re quired point it will act on the piston 6, and restrict the further admission of thesteam to the cylinder 4. Finally it will close the steam line altogether, and the entrance of the steam will cease till the temperature of the water falls and the volume contracts, thus allowing the spring to act and the piston to lift. By turning the wheel 31, the amount or extent to which the valve 8 is allowed to open, can be varied. I can in this way regulate the admission of steam to the cylinder so accurately that the radiation will be too rapid to allow the water to expand at all; or at least too rapid to permit the water to expand sutliciently to shuto'lf the steam altogether. This allows separate regulation for every individual apartment of the building in which the heating device is used; and it enables the occupant to get as much or as little heat as he desires or needs according to his surroundings. It provides in fact for regulation to suit every possible range of conditions that are likely to be met with in every day life. Another advantage of my invention resides in the fact that the casing 5 will prevent bursting of the radiator if the radiator 1 should ever freeze over night, after steam is turned off by the anitor. In such an event the water on congealing will simply fill the regulator casing, and damage will be avoided. The owner therefore need have no fear of accident at any time.

it will be seen therefore that my heating device is as simple as it is possible to make it; the construction of the same is easy and cheap; and any degree of regulation that is wanted can be had by the user simply ma nipulating the parts which determine the extent to which the steam line is to be allowed to open. The radiator casing can be flushed out at any time and replenished, and no skilled attendant is ever needed. Any housekeeper can understand the structure and operation of it and even neglect and ill usage cannot result in any serious trouble.

Having described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States is 1. in a heating device, the combination of a body forming a cap or closure and having a rib or flange on one side thereof, a hollow body having one end received by the cap and surrounded by the rib, said cap being adapted to support the hollow body in horizontal position projecting from the side of the cap, the hollow body having its outer end closed and forming with the cap a closed chamber, the cap having a passage leading to the inside of the hollow body adjacent to the lowest part of the same and adapted to drain said hollow body and having a second passage leading to the inside of the hollow body adjacent the highest part thereof, and a tube received by the inner end of the second passage and extending into the hollow body in close proximity to the top of the same, whereby when the tube operates as a vent tube, water collecting on the bottom of the hollow body will not be expelled therethrough.

2. In a heating device, the combination of a casing for receiving a medium adapted to store and radiate heat, a hollow body in the casing having its outer surface in contact with the medium, means for supplying to the inside of the body a noncombustible agent adapted to impart heat to the medium, said agent being kept out of direct contact with the medium by the walls of the body, a valve for controlling the admission of the agent to the body, a casing communicating with the first casing and having a piston therein, a rod connecting the valve and pisston, whereby the expansion of the medium will move the valve and finally close the same, resilient means in the piston casing opposing the action of said medium, said rod having a collar thereon, and a screwthrcaded sleeve carried by the piston casing and engaging the collar, said sleeve having a hand-wheel thereon, whereby the opening of the valve may be limited, or the valve closed independently of the expansion of the medium.

3. In a heating device, the combination of a casing for receiving a medium adapted to store and radiate heat, a hollow body in the casing having its outside surface in contact with the medium, means for supplying to the body an agent adapted to impart heat to the medium, said agent and medium being kept out of direct contact by the walls of the body, a valve having a rod comprising two adjustable sections for controlling the admission of the agent to the body, a casing communicating with the first casing and having a piston therein, said rod entering the said casing and being secured to the piston, whereby the expansion of the medium will move the valve and finally close the same, a yielding member opposing the action of the medium, said rod having a collar thereon, and a screw-tln'caded sleeve carried by the second casing and engaging the collar, said sleeve having a handwheel there on, whereby the opening of the valve may be limited or the valve closed independently of the expansion of the medium.

4. In a heating device, the combination of a casing, means for admitting an agent containing heat to the casing, said means including a valve, a second casing communicating with the first casing and having a piston therein, a rod connecting the valve and piston, said piston being movable in response to the pressure in the first casing to open and close the valve, said rod having a collar thereon, and a threaded sleeve carried by the -)iston casing and engaging the collar, said sleeve having a handviheel thereon, to limit the motion of the piston.

5. In a heating device, the combination of a casing, means for admitting an agent containing heat to the casing, said means including a valve, a second casing communicating With the first casing and having a piston therein, a rod connecting the valve and the piston, said piston being movable in response to the pressure in the first casing to open and close the valve, said rod COIH- prising two adjustable sections and having a collar thereon, and a threaded sleeve carried by the piston casing and engaging the collar said sleeve having a handwheel thereon, to limit the motion of the piston.
