HEATER.

SPECIFICATION forming part of Letters Patent N o. 671,992, dated April 16, 1901.

Application filed October 29, 1900. Serial No. 34,755. (No model.)

T all whom, it may concern:

Beit known that I, LOUIS DUTRIE, a citizen of the French Republic, and a resident of Steenwerck, Nord, France, have invented certain new and useful Improvements in Heaters., of which the followingjs a specification.

My present invention relates to heaters for rooms and the like, the object being to provide an apparatus of this kind in which a 1o normal and regul-ar circulation of water is obtained, which is readily put together and taken to pieces, and enables considerable sav-- ing of fuel to be eected; and it consists in the features of construction and the combi- 415 nation of parts fully described and claimed hereinafter.

In the accompanying'drawings, forming a portion of this specification, Figure l shows a side elevation of a heater constructed in aczo cordance with my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a rear end view. Fig. 4 is a front elevation-of the heater. Fig. 5 is a plan View showing the furnace. Fig. 6 shows diagrams hereinafter referred to.

Like characters refer to like parts throughout all the views.

The apparatus comprises, first, two series of three tubes a b c, a b' c', arranged paral- 3o lel to each other, so as to form the sides of the furnace, and connected at one end by means of tubular connections d d', Figs. 1 and 2. Each of the latter is provided with a lateral nozzle t u, tu', Figs. 4 and 5, which are to be connected with the lower-most part of the apparatus. At the opposite ends the tubes a. b c, a. b c' are connected with tubular connections r r', said connections being joined to .each other by means of two tubes 4o d c, d c, forming the rear walls of the furnace, Fig. 3. Arranged above the two series of tubes a, b c, a' b c' are a plurality of horizontal tubes l l 1, forming the top wall of the furnace and connected to said series by means of tubular connections, said tubes 1 l being arranged as shown in Fig. 6. Arranged above Said tubes 1 1 are other tubes 2 2 2, connected to the former bymeans of U-shaped connections r r2, Figs. l and 4. Said tubes 2 2 are 5o arranged and interconnected, as shown at C, Fig. 6. The tubes 2 2 are connected to a third series of horizontal tubes 3 3, similar to the tubes 1 l, B D, Fig. 6, and above said tubes 3 3 is a fourth series of tubes 4 4, connected by means of U-shaped connections u' u? and arranged, for instance, as shown at A, Fig. 6. A A designate two nozzles adapted to be connected to the canalizations. Said nozzles may of course be arranged in any desired manner. Hot Water flows through said nozzles out from the heater into the canalization and back into the heater through the above-named nozzles t u, t u.

As shown'in Figs. 2, 3, and 4, the tubes l 2 3 4 are arranged alternately or staggered, the couplings at the rear end inclining outwardly and those at the front end inclining inwardly, thus causing a thorough circulation of the products of combustion through them.

It is manifest that the number of series of horizontal tubes l l, 2 2, 3 3, 4 4. may be selected as required without departing from the scope of the invention.

The heater constructed as described is arranged within a casing M, made of suitable brickwork and provided with a front openingo for the introduction of fuel, and openings 0, serving for cleaning or repairing purposes.

The several tubes of the heaters are supported on a plurality of bars ff2 fj1 f5, the latter serving at the same time t0 support the front end of the grating.

The combustion products pass from the furnace through the spaces between the several tubes into the funnel c h, provided at the side of the brickwork and communicating with the chimney.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

In a heater, the combination of the tubes a b c, a' b c forming the lateral walls of the furnace, the tubular connections d, d atone end thereof, the connections r, r and transverse tubes d c, d c at the other end thereof to form the rear wall of the furnace, and the staggered horizontal` tubes l, 2, 3, dac., with their couplings inclined alternately in and out, forming the top wall of the furnace.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
