Application filed March 7, 1927. Serial No. 173,491.
The main objectof this invention is to-provide a combined mufiler and heater which is highly efficient and at the same time very economical to roduce.
5' A further ject is to provide a structure which may be quickly installed on motor vehicles in lieu of or supplementary to the mufiiers with which they are commonly provided.
()bjects pertaining to details and econ- .omies of my invention will definitely appear from the detailed description to follow. The invention is defined and pointed out in the claims.
A structure embodyingthe features of my invention is illustrated in the accompanying drawing, in which:
Fig- 1 is a detail view partially longitu-' dinal section on line 1-1 of Figs. 2 and 3 of a 2" combined mufiler and heater embodying the features of my invention.
Fig. 2 is a cross section one line corresponding to line 22 of Fig. 1.
A Fig. 3 is a cross section on line 3-3 of a Fig. 1.
Fig. 4 is a diagrammatic view illustrating the relation of my heater and mufiler to the parts of a motor. vehicle.
In the drawing similar reference characa ters refer to similar parts throughoutthe several views.
In the embodiment illustrated I provide an inner tubular wall- 1 and an outer tubular wall 2 arranged concentrically and providing 3., an elongated gas chamber 3 and a surrounding air chamber 4. These parts are supported in concentric relation by the front and rear collars 5 and-6. The rear collar is preferably fixedly secured to both walls as illus- 4o trated by welding while the front collar is secured to the outer wall by welding and slidably embraces the inner wall, the parts being brought to exact size for this slidable contact. The purpose of this is to permit rel- 4! .ative movement of the walls due to une ual expansion as they are heated and coole or unequally heated. I
The front collar is disposed in spaced relation to the front end of the inner wall so as 00- to permit the removal of the screws 7 by which the head member 8 is retained in the inner wall. This annular head member is,
in the embodiment illustrated, in the form of a casting and has an internal annular groove on 9 therein into which the sheet metal nipple 10 is expanded atll, thereby securing the nipple in place. This nipple is longitudinally slit at 12 to facilitate clamping engagement with the exhaust pipe or connectingpipe for the heated gases such as the exhaust gases of an internal combustion engine.
The head member has a reduced flange 13 at its inner end upon which the front end of the gas discharge pipe 14 is slidably supported centrally within the gas chamber 3. This slidable support allows for longitudinal movement to care for unequal expansion between discharge pipe and inner wall. The.
rear end of the gas discharge pipe is centrally supported by the end head 15 of the gas chamber. This end head is preferably welded within the wall of the gas chamber and also to the rear end of the gas discharge pipe, completely closing the rear end of the gas chamber.
The-discharge pipe has a partition 16 adjacent to but spaced from its rear end and in front of this partition the discharge pipe has a plurality of discharge orifices 17 grouped around it so that the heated gases are discharged from these orifices against the inner wall 1 and flow rearwardly within the gas chamber to a series of holes 18 which are arranged at the rear of the partition 16; the holes 18 being of such capacity as to permit the exhaust gases to re-enter the discharge pipe without material back pressure so that the products of combustion flow freely through the, gas chamber. The rear end of the discharge pipe projects beyond the wall 15 so that it constitutes a coupling member, which can be attached to the gases to the rear of the car. i
The air chamber is provided with a tangentially disposed air inlet connection 20 and L a tangentially disposed air outlet connection 21 so that the air is directed in a spiral path through the air chamber.
To further insure the air taking this spiral a tail pipe carrying path Iprovide a spiral bafile 22 which is mounted upon the inner wall adjacent the intake. This baffle is not connected to the outer wall although its outer edge lies close thereto.
. A LA In Fig. 4 I illustrate my improved heater in 1 operative relation to an internal combustion engine 23; the exhaust pipe 24 being connected to the nipple 10. An air intake pipe 25 with a flaring mouth 26 is connected to the intake 20 while a tail pipe 27 is connected to the rear end of the gas discharge pipe which has a longitudinal slot 28 therein to facilitate clamping connection. 29 indicates a register connected to the air outlet 21 and controlled by a valve mechanism indicated at 30. In the embodiment illustrated, I provide an insulated covering 31 for the outer wall. I
I have illustrated and described my im provements in a practical embodiment but I desire to point out that the same may be considerably varied in structure without departing from my improvements.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a device of the class described, the combination of concentrically disposed inner and outer tubular walls providing a central elongated gas chamber and a surrounding air chamber, said air chamber having inlet and outlet openings at the respective ends thereof, front and rear supporting collars for said outer wall closing theendsofsaid air chamber, one of said supporting collars being disconnected from one of said walls permitting relative movement of said walls due to unequal expansion, a coupling member removably secured within the front end of the inner wall and provided with an inwardly projecting flange, a rearwardly tapered discharge pipe disposed centrally within said gas chamber with its front end slidably engaging the rojecting flange from said coupling mem er, thus permitting relative movement of the inner wall and discharge pipe due to unequal expansion, said discharge pipe having a partition spaced from its rear end, with a plurality of discharge orifices around it in front of said partition and a plurality of exhaust openings at the rear, of said partition, and a conical end head for said gas chamber tightly fixed to the rear of said inner wall and to said discharge pipe at the rear of its discharge openings, said discharge pipe projecting beyond said rear head to provide a coupling member,
.2. In a device of the class described, the combination of concentrically disposed inner and outer tubular walls providing a central elongated gas chamber and a surrounding air chamber, said air chamber having inlet and outlet openings at the respective ends thereof, a coupling member removably secured within the front end of the inner wall, a rearwardly tapered discharge pipe disposed centrally within said gas chamber with its front end slidably engaging said coupling member, said discharge pi e having a'partition spaced from its rear en with a plurality of discharge orifices around it in front of said partition and a plurality of exhaust openings at the rear of said partition, and a conical rear head for said gas chamber fixed to the rear of the inner wall and to said discharge pipe at the rear of its discharge openings, said discharge pipe projecting beyond said rearhead to provide a coupling member.
In witness whereof I have hereunto set my hand. a
