COMBINED room-WARMER AND MUFFLER'.
Specification of -Letters Patent.
To al 'u1/wm t may concern Be it known that I, MILBURN GAR- .RIsoN, a citizen of the United States, residing at Ocean City, in the county of Cape May and State of New Jersey, .have inventhas for its principal object the providing of a construction and arrangement of parts whereby the exhaust gases, result-ing from combustion of fuel for propulsion purposes,
ma be utilized for heating purposes. further object of the p-resent invention is to'pi'ovide a combined foot vwarmer and muffler so constructed and arranged that the exhaust gases may pass freely, with little or no noise, therethrough without the production of undesirable back pressure.`
A still further object of fthe present vinvention is to rovide a construction and arrangement of parts whereby the exhaust gases from an internal combustion engine may be caused to pass in the ordinary and well understood manner through a-imuiiier; or
said gases may be caused toexhaustlpartly through the combined foot Warmer and muiiier of t-he invention and partly through` .f
' an automobile of any approved construction an ordinary mutiler; or if desired said gases may be caused to exhaust entirely throughy compact, durable, efficient and comparatively inexpensive vcombined foot warmer and muffler, which may be readily attached to automobiles, motor boats, launches, air ships or the like without necessitating reconstruction or material changeV of the conveyance parts.
Other objects of the invention` relate to the providing of general details of c'onstruction and arrangement of'parts` as will hereinafter appear.
With these and other objects in view the invention consists of the improvements hereinafter'described and finally claimed, ref.- erence being had to the accompanying drawings forming part hereof and in which:

T he combined foot warmer andmuiiler of the invention is intended to be primarily appli/ed to automobiles and like conveyances. It will be readilyunderstood, however, that the parts about to be described may with equal readiness be applied to motor boats, launches, air ships and the like, in consequence of which, the following description taken in connection with the accompanying drawings wherein an automobilek is shown and d escribed as being equipped with the apparat-us'of the invention,'is merely for illus'- trative purposes.
Referring to the drawings 10, designates equipped with an internal combustion engine 11, the cylinders of--which discharge into a commonexhaust pipe 12, connected with an ordinary muffler 13. Intermediate the engine 11, 'and muiiler 13, the exhaust pipe 12, isA divided into two sections and equipped with a bifurcated valve casing 14, the inlet end 15, of which receives `Vthat end of 'the exhaust pipe 12, adjacent the engine and the outlet ends 16, and' 17, of `which re-` spectivelyreceive the other section of the exhaust pipe 12, and a pipe or connection 18, which leads to the combined foot warmer and muiiler 19, of the invention. The combined footwarmer and muiier 19, is shown as comprising a generally rectangular elongated two-part casting of which the base 20, constitutes a shallow open top or dish-like casing` and of which the top comprises a removable cover 21. The base or casing 20, is marginally flanged as at 22, said flange being i. formed integral with the casing parts and "being provided with screw or bolt receiving vopenings-23. The base oi' casing is provided with an inlet port 24, in one side of the casing adjacent one end thereof and is provided with an o itlet port 25, upon its opposite side adjacent the other end of the casing. n These inlet and. outlet ports are formed by first swelling out, as at 26, the bottom of the base or casing 20, to form a depression, see Figs. 3, and 5, and by providing the side walls of the base or casing with screw-threaded socket-s of a diameter equal to the width of the depression for the reception of suitable pipings. As shown in Fig. 5, this brings the inlet and outlet ports substantially below the plane of the bottom of the base or casing 20, for a purpose to be presently described. Within the base or casing 20, and preferably formed integral with `the side walls of the base or casing are vertically arranged transversely extending baiiie plates'27, and 28. These baie platesv are disposed between the ports 24, and 25, and are suitably spaced `with respect to the ends o'f the casing and to each other and extend from the same wall of the base or casing that has a port therein, or more properly speaking said battles extend from the oppositeside walls of said base or casing. As shown in Fig. 4, they terminate short of the opposite 'casing wall. In other words, the baiiles divide the casing interior into compartments of equal size which constitute expansion chambers, three being shown in the drawings. 4
are substantially below the plane of the two end expansion chambers said two end expansion chambers are of equal area to the center expansion chamber. Thus exhaust gases may pass freely through the combined foot warmer andfmuitler witho-ut the production of any undesirable back pressure calculated to retard the speed'of the engine or such as would tend to stop the' engine particularly when the same is being cranked preliminary to starting the same. Also this spacing of the battles serves to reduce to a minimum, noise within the combined foot warmer and muffler when exhaust gases are passing therethrough. This is true because as gases first enter the end Aexpansion comvpartment they expand and as they pass around the first battle they somewhat co-ntract only to immediately expand in the next expansion. compartment and so on in regular vsuccession to the exhaust portl without choking or back pressure. Another advan` tage possessed of .spacing the battles is that ample room is present within the base or casing to prevent clogging of the parts by virtue of deposits of carbo-n from the waste gases, which cake and are very dilicult to remove from crowded spaces. In the present Case as the base .or casing is shallow and the expansion chambers unobstructed, and of large area cleaning of the parts ina-y be By virtue of the fact that the inlet and exhaust ports readily efected. By removing the cover 21, access may be readily had to the base or casing interior by virtue of its open top. This cover 21, considered in plan is -of the 'same relative outline .as the base or casing but it is of larger dimensions, so that its marginal edges project considerably beyond the marginal flanges of the base or casing. 20. The cover 21, is provided in its marginal flanges with counter-sunk openings 29, for the reception of screws, bolts or the like 30, for securing the combined foot warmer and muffier to the floor 31, 'of the automobile 10, see Fig. 5. In this connection, it may be remarked that the cover 21, is further provided with counter-sunk openings adapted to register with the openings 23,-of the flanges of the base or casing 20, for the reception of screws, bolts or the like 32, for securing the cover with respect to, the base or casing 20. Between the flanged portion of the base 20, and the bottom of the cover 21, is a packing of asbestos 45, to prevent the escape of gases to the conveyance being heated. It may be here stated that in practice, the Hoor 31, has made there` in an opening so that the base or casing 20, may be passed therethrough the anged portion of the base or casing resting upon the counter-sunk portion 33, of the floor. The flooring is further counter-sunk as at 34, so that the marginal portions of the cover come flush with the top of the iooring. The cover is then secured to the flooring and to theIbase or casing as before described and as shown in Fig. 5. Formed integral with the top of the cover 21, are parallel longitudinally extending ribs As shown these ribs are not continuous but constitute a series 4of short suitably spaced sect-ions, alternate rows of ribs of which overlap the spaces between the sections of the other rows. By this construction and arrangement of parts a large heat radiating surface `is provided. It has been demonstrated in practice that it is necessary to make the ribs of short sectio-ns because of the fact that in casting, the cover cannot be withdrawn from t-he sand box 'if the ribs are continuous. In use these ribs serve to form a convenient foot rest for the occupants of an automobile, motor boat, launch, air ship or the like. The bottom of' the cover 21, is provided with depending Hanges 36, which serve as guides to properly aline the. openings of the cover with the openings 23, of the flanged base or casing.
As shown in Figs. 1, and 2, a'pair of com-v bined yfoot warmers and mutilers are disclosed. In this connection, it may be rel marked that one of the footy warmers and muttlers is located at the rear end of the hood of the automobile and the other is positioned at the rear of the seat of the operator. IVhere a pair of combined foot warmers and muiiiers are used a pipe or connec-v tion 37, couples together the. pair of foot warmers and mutliers and an exhaust connection 38, leads tothe atmospheric air from the rear foot warmer and muiiier. For controlling the passage of exhaust gases through the mutller 13, or partly through the mutler 13, and partly through the combined foot warmer and muiiier of the invention or entirely through the combined foot warmer and muiiler, useis made of the hereinbefore mentioned valve. As shown in Figs. l, and 2, the bi-urcated valve casing 14, is arranged adjacent the foot board of the automobile 10, and has extending upwardly therefrom' through the said foot board a manipulating handle 38. This handle 38, is equipped with a valve 39, of damper like construction, see Figs. 6, and 7, and is mounted for partial rotation through the valve casing. In operation, if it is desired to exhaust all of the waste products. of combustion from the engine through the combined foot warmer and muiiier the damper-like valve 39, is moved to the position shown by full lines in Fig. 7. If desired `to cut out the combined footwarmer and muflier entirely and exhaust through the mutller 13, the damper-like valve 39, is moved to the position shown by dotted lines in Fig. 7. Obviously, movement of the damper-like valve to a point intermediate of these two extreme points will. cause waste products of combustion from the enginel to` pass partially through. the combined foot warmer and mutiler and partially', through themutlier 13. A convenient form of securing the pipes 12, and 18, with respect to the valve casing is to provide the various branches of the valve casing with split ends 40, and clamp said pipes with respect to said valve casing by means of bolts .41.
