To all whom it 'may concern."

Be it lrnown that l, STANISLAW d'. linien sznwsKr, a citizen of the United States, and residing at Detroit, in the county of llayne and State oi Michigan, have invented a new and Tmproved Heater, of which the following is a speeilication.

This invention relates to heaters especially adapted to lreep warm the' engines ot motor vehicles during cold weather as set forth in my Patent No. 1,007,710, dated November i', 1911, and the object of this invention is to provide a heater `which will not be extin# guished when the vehicle is passing over rough roads or during stormy weather, and which will permit of an easy removal of the burner at all times.

This invention consists, in combination with a coil and a shell around it, oli' a base below the shell and which is provided with novel batde plates to control the currents ot air, ot a novel air inlet chamber extending over one end o1 the base, oit a fiue for excess air extending up the outside of the shell, of a l' burner below the coil, a burner, and novel means for mounting the burner within the base. 1t further consists in the details et construction illustrated in the accompanying drawings and particularly pointed out in the claims. t

Tn the drawings, Figure 1' is a central vertical section oit this improved heater. Fig". 2 is a section oi the burner on the line 2--2 o1 .lligz l. llig". 0 is a horizontal section through a support .tor the coils. Fig. i

is a section on the line t-fl of ligg. l. lig;

ii is a section on the line '5 of Fig. d.

Similar reference characters reiter to lilre parte throughout the several views. y

The shell in which the coils 1 and 2 are mounted is preferably termed olf two metal sheets 3 and t, preferably steel, and a sheet o1 asbestos between themu it top plate or diaphragm 5 is perforated to permit the escape oi' burnt gases and may be termed with small pedestals 0 to support a coolrine; uten sil it desired. The removable hood is formed oi a tapering; body 'l' having a Harige 8 and a. chimney 9. A ring" is carried by ears 11 on a thinible 12 and supports the cap 13 by means oi the ears 1t.

The coils 1 and 2 are secured at their ends in proper holes in the littings 15 (llig. 3), held in position in the shell by means of screws 16. The inlet pipe 17 and outlet pipe 10 for the water to be heated connect into these httings.

' as shown in llig. 5.,

The door is formed oi a sheet oi metal 23 and an asbestos lining 2&1-, secured in po sition by means of the screws The side edges 26 oi the door may extend over 'the posts 21, the bottom edge 2l may entend over the base and the top edge may be folded down over the lining as shown in llig. 1. The burner is mounted on this door and can be slipped into and out ci position as de# sired.

The body B0 oi the burner has a horizon tal bore to receive the needle valve 31 and has a horizontal discharge orilice 32. l fuel supply pipe connects to the nipple '33 and the fuel passes through the combined hlter and storage chamber 341-. This storage i chamber will usually contain sutlicient liquid `fuel to leed the Haine while the supply tanlr is being reiilled, the l'uel in the supply charnber vaporizingl during such time. The post on the body supports a burner ring 30 having' the usual slots 3l', intalte openingn 38 and passages 39 to permit to burn around the post and above the body 'l0 ot the burner to heat the post and body.- il delector plate l0 at the top ci" the post causes the llame to pass up between the coils instead oi up through the inner coil. The tl-shaped mixing,r tube ll2 has a downward extension 113 which catches the liquid iuel which may drip from the orilice 32 and con veys it to the igniter.

The igniter is secured to the base in any' desirable manner and is imormed with a trough t5, an ovcrilow Llt that regulates the height oit 'fuel in the trough, air passages Il?, aperi'orated thiinble 4th and a perforated. ring t9. The fuel in this trough may be ignited by inserting a taper or a wire tipped with a ball ofiiber soaked in alcohol through the opening in the door shown in liig. et, where a threaded bushing,1 receives the plug 51. This plug; may be temporarily removed but must be replaced to prevent igni tion oi any gas-clone diurnes which might be in the air oi the room where the burner is used lltl 'tti

lllll ltlli An air chamber fits around a lateral exten# sion of the base and is preferably no wider than the shell. The free edges of its sides 52 are preferably secured to the sides 58 of the extension of the base by means ofthe screws 54, its top 55 is suiliciently above the bottomof the base to insure a large quantity of inert air, and its bottom 56 is perforated to admit air. A small cross plate 59 connected to the sides 52 may be used to close the space between the bottom 56 and the base of the heater. j

The sides 53 of the base preferably converge and are integral with the rounded end which leaves a considerable air passage between it and at least one of the sides or the outer end 58 of the air chamber. 'A cross bar 57 extends between the sides of the base and below it is a box-like case 60 to receive the U-shaped tube 42. A horironthen bends up to this ease. -A second baille plate 63 extends down from the bottom of the shell at the top of the case 6() on each side of this U-shaped tube to the bottom of the case 60 and then bends back toward the plate 62 to form an intercepter 64.

A flue or passage 65 is formed by the side plates 66 which are preferably portions of the shell, as shown in Fig. 4, and the outer plate 67. A passage 68 in the shell just below the top plate 5 permits the air which rises in the flue 65 to enter the shell. A second plate 69 holds the sheet of asbestos 7 0 in position, which prevents heat passing to the air chamber, thus keeping the flue warm and causing the air therein to rise.

After the fuel in the igniter trough 45 is burning, it heats the body of the burner and vaporizes the fuel which passes to the burner ring and is there ignited by the flame of the liquid fuel in the trough. Air enters through the perforations in the plate 56 and passes up into the air chamber and then down into the base. Some of this air passes between the baille plates directly te the burner; the remainder is thrown up by the inner edge 7l of the plate 62 and impinges on the plate 63 and passes up the flue 65 and out through the passage 68 and the perforated top 5 of the shell. Any sudden gust or blast of airl entering through the holes in the plate 56 will be cushioned by the air in the air chamber, and if the current down into the base is swift, the air will be mostly deflected to the flue 65. No more air passes down around the deilector 64 than is necessary for the burner, and most severe tests have shown that the flame of the burner cannot be extinguished by high winds or by jars.

I claim 1. In a heater, the combination of a cylindrical shell, a heating coil therein, a burner below the coil, a base upon one end of which the shell is mounted and provided with a lateral extension, a door at one end of the heater and means to secure the burner to said door, an air chamber slidable onto the extension of said base and spaced therefrom at at least one side and having a perforated lower end and a closed upper end, baille plates mounted within the base, and a passage for excess air extending up from said base along the shell.
