UNITED STATES- 1,563,402 PATENT oFF-ICE.-
ELMER RYDER, OF BERWYN, ILLINOIS.
MOTOR-CAR HETER.
Application filed Maren 1a, 1924. serial No. 699,079.
-more particularly to heaters of the flush type, that is those set in the floor of the car and heated by running the exhaust gases through hollow casings.
-One object of my invention is to stamp the heater casings from sheet metal so that expensive castings, which require machining as heretofore, are avoided.
Another object of my invention isto make the heater casings in sections and. connect them .together where joined by crimp-like seams.
A further object of my invention is to combine in a` single fitting the inlet and outlet for the exhaust gases, and moreover construct the inlet part ofthe fitting that direct impact 'of the incominggas against the sheet metaly heater is avoided to prevent rumbling.
Other and further objects of my invention will appear from the following specification taken in connection with the accompanying drawings, in which- Fig. 1 isa vertical longitudinal sectional view taken through a heater assembly of my invention;
Fig. 2 1s a transverse vertical sectionalv view taken on line 2-2 of Fig. 1';
Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 1; and
Fig. 4 is a horlzontal sectional view on 1 In the drawings,l1 indicates the floor of an automobile, cut out to provide a rectangular opening 2te receive the heater'assembly of my invention. This device comprises a 'a metal pan 3 having a marginal flange 4 se,-
cured to the floor 1 about the opening 2.
Extending over thetop of the pan 3 1s a register plate 4 having its edges restinof on the 'flange 4. as shown, and secured in p ace in any suitable manner.
Located in the pan 3 is a heater casing 5 stamped from sheet meta-l and consisting of upper and lower sections 6, 7 secured together. Each section, as shown, forms half of the casing and the lower section 7 has an closed end an outwardly projecting flange 8` about its upper margin. 'The upper section 6 has a f flange 9 seating on the flange 8 and turned and clamped about the same to secure thc sections. together. The joint is made gas tight by crimping or clamping the flanges together.
The casing 5 is divided into upper and lower compartments or chalnbers 10, 11 by a horizontal partition wall 12. The margin of this wall extends to the flanges '8, 9 and is clamped between them. As shown in Fig. 3. the partition wall 12 is provided with a plurality of holes or apertures 13, 13 extending in a row about half way around one end of the same.
At the opposite end ofthe casing 5 is a fitting 14, preferably a casting and made to have a gas inlet extension 15 and a gas outletextension 16. These extensions are below the bottom walls of the casting` and pan and f The inlet extension 15 continues -into a tubular section 17, which extends upward across the lower chamber 11 through a hole 18 in the bottom wall of the casing 5. This section 17 terminates at its upper end into a drumlike' ortion 19, which drum has a (Pl projects into the upper chamber 10 through a hole 20 in the partition wall 12, as shown in Fig. 2. The drum has aplurality of .holes 21 in its side wall to chamber is through the extension `16,` as
shown in Fig. 2.v
' The fitting 14 is cast with a circular flangeV 22 to be secured to the bottom of the heater casing 5 over the hole 18. The pipe extension 17 is substantially semicircular in crosssection, with its fiat wall dividing the passages 15 and 16 at the flange 22, as shown in Figs. 2 and 4. By removing lthe fitting 14, the heater casing 5 may be cleaned on its removal from-the pan3.
The casing 5`may besecured in the pan 3 '90 'discharge exhaust gases into said upper in any suitable way, as by screws 23 in Fig. l, with an asbestos gasket 24 interposed between. the pan and casing. The structure shpwn and described may be -variously changed and modified without departingv 4the marginal portlons of the two sections and spaced from the top and bottom walls of the heating chamber to divide 'said chamber into two compartments, an exhaust inlet communicating with one of said compartments, an outlet communicating with the other compartment, and means in the said artition plate permitting communicartion etween the two compartments.
2. A motor vehicle heater, -comprising Va hollow casing of sheet' metal, a sheet metal partition wall dividing the casing mto up'- per and lower chambers communicating by holes in the partition wall, and a combined inlet andoutlet fitting applied to said casing and having its outlet section opening into the lower chamber and its inlet section opening into the upper chamber by extending through the lower chamber and said partition wall.
3. Amotor vehicle heater, comprising a hollow casin of sheet metal, a sheet metal partition wa l dividing the casing into upper and lower chambers communlcating by a row of holes around one end of the partition wall, and a combined inlet and outlet fitting applied to the opposite end of the casin and having its outlet section opening into t e lower chamber and its inlet section opening into the upper chamber by extending through the lower chamber and said partition wall.
4. A motor vehicle heater, comprising a hollow casing,l a horizontal partition wall dividing the casing into upper and lower chambers communicating 'by holes in the partition wall, and a combined inlet and outlet fitting applied to said casing with its outlet section opening into the lower chamber and its inlet section extending through the lower chamber and said partition wall and opening into the u per chamber through a drum like portion aving discharge openings in the side wall thereof.
In testimony that I claim the foregoing as my invention, I aflix my signature this 12th dayfof March, 1924.
