RICHARD HOUSE, JR., OF ELIZABETH, NEW JERSEY, ASSIGNOR TO THE BOYNTON FUR- NACE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
FURNACE.
T 0 all whom it may concern:
Be it known that I, Riemann ltocsn, J r., of the city of Elizabeth, county of Union, and State of New Jersey, have invented a new and useful Improvement in Furnaces, of which the following is a full, clear, and exact description.
I My invention relates to improvements in hot air furnaces.
My invention relates especially to the means of connecting a smoke pipe to a furnace of the kind referred to, and for providing a clean-out opening. Usually it is the practice in furnaces of this character to have a thimble or flange around an opening through the radiator wall, and when the furnace is set up, a hole is cut through the outer casing so that the smoke pipe may eX- tend through the said outer casing and connect with the aforesaid flange or thimble, then a collar is put on around the smoke pipe; but in practice it is a very difficult matter to cut the opening so that it will register accurately with the inner flange or thimble, and further it is almost impossible to make a tight oint which will prevent smoke and heat from issuing around the pipe to a certain extent. I obviate this difficulty by producing a structure which enables the space between the radiator wall and the outer casing to be bridged by a thimble which surrounds the radiator holes, and then the holes in the outer casing can be made to register with reasonable accuracy with the aforesaid thimbles, and finally a collar is clamped around the opening through the outer casing and fastened to the inner thimble, so that a tight vent is produced leading from the radiator through the outer casing. I make this construction in at least two parts of the furnace, preferably parts which are diametrically opposite or nearly so, and one of these devices-that is one of the outer collarsis arranged to connect with the smoke pipe, while the opposite as a clean-out opening. As the two opposed parts are similar, it will be seen that it greatly facilitates the setting up of the furnace, as thefurnace can be placed in the most convenient position and the collar nearest the chimney can be used to connect with the smoke pipe. The construction which I have above referred to thus has the advantage of making a tight connection between Specification of Letters Patent. Patented Sept, 14, 1905),
Application filed September 29, 1908.
Serial No. 455,259.
the radiator and the smoke pipe, also it has the advantage of enabling the furnace to be set up conveniently as stated, and moreover the structure is cheap and simple as will presently appear.
Reference is to be had to the accompany mg drawings forming a part of thls specification, in which similar reference characters indicate corresponding parts in all the views.
Figure 1 is a horizontal section through the furnace, Fig. 2 is an elevation of the outer ring inclosure, and Fig. 3 is a sectional elevation through the connection.
I have shown a common type of hot air furnace having the inner two walled fire box 10, the radiator wall 11, and the outer casing 12. Fig. 1 also illustrates the usual door 12 and the inner opening 11 through the radiator. All this, however, is immaterial to my improvements, and the inner structure of the furnace can be of any approved type. It is understood that in such furnaces provision must be made to let the smoke escape from the radiator 11 and through the outer casing 12. To provide for this I use an inner thimble 13 which has a flange 14: adapted to fit against the wall 11, and large enough to extend around the customary opening through such wall. The thimble is preferably smaller in circumference at its outer edge than at its inner edge, and the inner edge is preferably bulged or convexed while the outer edge is concaved or dished at the flanged portions thereof. In my case, I have these openings on opposite parts ofthe radiator, and consequently there are two thimbles 13, and two sets of acces sory parts, as shown on the drawings, but I will describe one. The thimble 13 is of such length as to just fill the space between the walls 11 and 12, and any slight deviation is of course readily provided for by the flexibility of the wall 12. The flange M is riveted to the wall 11 as shown in Fig. 3, and the outer part of the thimble 13 is provided with an in-turned flange 15, with a marginal lip 15 around the smoke opening.
fit can be made between the thimble 13 and casing 12 which is not necessarily a nice one, and the lip 15 can extend around the edge of the opening through the part 12. An angular collar is clamped to the outer part of the casing 12, and this collar has a flange 16 which comes opposite the flange 15 of the thimble 13, and the parts .15 and 16 can be securely bolted together through the aforesaid parts, so that the outer and inner parts of the smoke conductor 13-17, are firmly secured together and clamped around the casing 12.
The angular collar, above mentioned, has an outwardly extending cylindrical part 17 and also an inturned flange 18 with slots 19 in opposite sides thereof which are adapted to receive the projections 20 of the bolts 21 which project inward through the cover plate 22. This part has a hand hold 23 by which it can be turned, and when the parts 20 register with the slots 19, the plate can be removed; but when they are turned out of registry the cover plate is locked to place in a manner well known in constructions of this sort. The smoke pipe 24 can connect with either projection 17 of the clamping collar. It will thus be seen that it is very easy to set up a furnace at a desired point, and that as the smoke pipe 2a can connect with either part 17 of the furnace, the opposed part can be used as a clean-out opening.
In practice the parts 13, 17 and 22 can be conveniently cast, so that the construction is very cheap, and it will be seen that it is easily applied and serves the purpose required perfectly.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a furnace having a radiator and an outer casing with approximately registering smoke openings therethrough, a thimble fitting against the radiator around the opening and having an outer flange with a marginal lip extending into the smoke opening of the casing and lying essentially flush with the outer surface of said outer casing, and an outer collar having a flange arranged to be clamped against the casing and against the outer flange of the thimble.
2. A furnace having an inner radiator, and outer casing, the two said parts having corresponding smoke openings, a thimble secured around the opening of the radiator and extending to the outer casing where it merges in a flange fitting against said casing and around the smoke opening, a collar fltting around the smoke opening in the easing and having a flange adapted to fasten to the outer flange of the aforesaid thimble and an in-turned flange at its outer extremity, and a closurehaving bolts engaging the in-turned flange of the collar said inturned flange'having slots for the removal of said bolts. 4 I r a 8. A furnace, havin a radiator and an outer casing, both provided with registering smoke openings, a thimble connecting with the radiator around the opening therein, said thimble having an inwardly extending flange lying flush with the outer face of the casing, and a collar having an outwardly extending flange secured flush with the edge of the inwardly extending flange of the thimble and an inwardly extending flange on the opposite edge, said latter flange being provided with means for securing a closure thereto.
4. In a furnace the combination with the radiator and the outer casing, both provided with smoke openings at diametrically opposite parts of the furnace, of a thimble secured to the radiator around the opening therein, and to the casing flush with the outer face thereof, and a collar having an outwardly extending flange secured to the thimble and casing, said collar also having an inwardly extending flange adapting the same for attachment with a pipe.
5. In a furnace the combination with the inner wall and the outer casing, both prorically opposite parts of the furnace, of a thimble having a convexed inner edge'provided with an outwardly extending flange secured to the inner wall around the opening therein, said thimble also having a con caved outer edge provided with an inwardly extending flange having an outwardly extending marginal lip lying flush with the outer face of the casing and a collar having an outwardly extending flange secured with said casing and thimble.
6. In a furnace the combination with the inner wall and the outer casing both provided with registering openings, of a' thimble secured to the inner wall around the opening and to the casing, a collar secured to the thimble and casing, said collar having an inwardly extending flange provided with slots and a cover having lockingbolts, said cover being provided with means for moving said slots and bolts into and out of registration.
