As a Yfurther safeguard and to prevent manipulation by means of the 'free end of the Wire a slot 21 is formed near the lower end of the plunger 6 and on 'the exterior of the cylinder 5 a spring ring 22 .having .an end 2B inwardly projecting through the hole 24 is provided. llf the tube ,8 .and Wire lC? are cut, the plunger .6 is vforced upwards by .the spring l0 until the .end 23 enters the slot 2l whereupon the lplunger vis secured so 'that .air holes .3 are uncovered.

The device does not make .it absolutely impossible to start the engine, but the time .necessary to do so vvhe-n the device is 'fitted would .in mos-t cases prevent theft.

ln the .above description the `cap 14 is described .fixed in position by sere-Ws 1'5 and an `.overlying ring of solder. It is robvious lthat this cap may .be secured in any Well known manner as, for example, by rivets or yother equivalent devices.

Vile claim l. Apparatus for the purposes `specified Compris-ing fin ycombination with the indu'ction pipe of ya vehicle fengine "an extra air device yconnected with the induction .pipe vand :a loosely iittfing perforated sleeve `enveloping 'said device.

:2. The combi-nation with the :induction pipe of engine, of an .eXtra air device connected with :the induction pipe, means 'for locking said device anda perforated rough- 'ened .sleeve 'enveloping :said device.

3. A device for the purposes specified including in combination With'the induction pipe 'of fan engine, :an extra air device :adapted normally to .give 'full opening to the induction pipe, a rotatable perfor-ated 'sleeve .surrounding said device, means for :securely retaining said sleeve and means for locking said extra air device.

i. A =device for the purposes specified including in combination With the induction pipe of an engine, ian eXtra air apparatus adapted'norm'ally to maintain full communication between the induction pipe and the atmosphere, a 'roughened perforated sleeve surrounding said device, means for securely retaining said sleeve, means for operating and 'locking said eXtra air appara- 'tus and means for automatically rendering Asaid .apparatus .inoperative upon the severvance of the connection to the locking means.

5. A. device .for the purposes specified comprising in combination an extra air device Which .consists of a .cylindrical vessel in .commami'cation With the .induction pipe and liaving .peripheral .holes therein, a plunger adapted to be external-ly operated and a .spring Vadapted normally -to operate said plmiger to establish fullcommunication between the atmosphere and the vinduction pipe, a roughened perforated enveloping sleeve, means for securely retaining said sleeve,means for l'opcrafting and flocking said entr-a air :device and .means for automatically .rendering said plunger inoperative on the Y.f-everan'cev :of the connect-ion to the locking means.

6. A device as claimed in claim v5, wherein the plunger' .is provided with a circumferential groove zand Whe-rein the casing is provided with 'a hole and `wherein the means for automatically render-ing the Yextra air device inoperative :includes a spring ring surrounding the casing, and having an inwardly projecting end passing through said :hole and :adapted for 'engagement with the circumferential groove in the plunger.

7,. Ari ali-rangement ofthe character described including fthe combination with the induction :manifold fof `an engine of an extra fair device in communication therewith and a protecting `sleeve 'surrounding the device consisting 'of a cap-like body, the outer sur- :face fof'the 'side Walls of which are provided with corrugati'ons Vvand with 'opening-s, Yand means 'for :rotatably securing the 'cap-like body imposition.

58. arrangement fas claimed in claim 7, wherein the extra air device includes a .cylindrical perforated vessel attached to the induction pipe, and va cap Vclosing the upper end of said vessel and acting to secure the -fs'l'eeive position.
