Patented Sept. 13,


citizen of the United States, residin UNITED STATES PATENT OFFICE.



Application filed larch 15, 1920. Serial No. 365,888.

To all whom it may concern Be it known that I, BRUCE W. AVERY, a Whiting, in the county of Lake and tate of Indiana, have invented new and useful .Improvements in Exhaust-Gas Conveyers,

of which the following is a specification.

This invention relates to means for conducting. the exhaust gases of automobiles,

-motors, stationary engines and the like to the exterior of garages or other buildings so that said gases will not remain in the.

through a wall of the building, and having a ,means whereby it may be easily and quickly attached to' the outlet end of the muflier of the engine.

Another object of the invention is to provide means for holding the pipe or pipes 'out of the way when not in use.

This invention also consists, in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the. appended c anus.

In describing my invention indetail, reference will be had to the accompanying drawings wherein like characters denote like or correspondin partsthroughout the several views, and m which Figure 1 is a sectional view through a portion of the garage showing the simplest form of the invention.

Fig. 2 is a like view showing theinvention 1n use in a large garage. I

Fig. 3 is a detail sectional view of Fig. 2.

Fig. 4 is a sectional detail view showing the means for connecting the flexible tube with the outlet of the exhaust.

Fig. 1. shows the invention in use on a private garage for holding a single car.

In th1s view a pipe 1 1s passed-through a wall 2 of the garage so that its end projects from the exterior of the wall. The

inner end of this ipe has a flexible tube 3 connected therewlth and this tube is long enough to extend to the outlet 4 of the muffler 5 of the automobile. The end of the tube is connected with said outlet by a set screw Q or the like,

'It will thus beseen that when the engine of the car is running the exhaust gases will be carried to the exterior of the garage so that a person may tuneup the engine or test the same with the garage doors shut and not be in danger of being injured by the exhaust gases. v

Fig.2 shows the invention applied to a large garage. In this form of the invention a main pipe 7 is located in the building with one end leading to theexterior thereof. Couplings 8 are located in said pipe and these couplings receive the ends of the flexible tubes 9. These tubes are each provided with the set screw 6' by which the tube ma be connected with the muliier of the car.

also rovide means for holding the tubes in raise position so that they will be out of the way when not in use. Such means may consist of a cable 10 having a hook at Specification of Letters Patent. Patented Sept, .13, 1921,

one end for engaging each tubeand a weight 11v at. its other end, said cable passing over a pulley 12. In this way when it is desired to start the motor of the car the attendant would first take hold of the end of the tube ulling the samedown against the action of with the muffler. In this way the gases will ass through the tube into the pipe 7 and mm this pipe to the exterior of the building. Check valves may be placed in the tubes to prevent'the when the tube is not in use.

' It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make, changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall withlnthe scope of the appended claim.
