`Application kfiled. September 8, 1924; Serial No. 736,569.

This invention relatesto ventilators, and is illustrated'as embodied in a cowl ventilator for a Cadillac automobile. An object of the invention is to provide means operated by the ventilator handle forholding the ventilator in vrany desired position. In one desirable arrangement, swinging the handle in either direction first disengages a holding pawl and then moves'the ventilator. Various features of the invention, and the advantages of the Ydescribed construction,

will be apparent `from the following description Vof one illustrative embodiment shown in the accompanying drawings, in which: Y v

Figure l is a vertical longitudinal section through a part of the cowl and through the cowl ventilator;

AFigure 2 is a transverse section on the line 2 2 of Figure 1;'and y n Figure 3 is a vertical section on the line 3-3 of Figure 2, showing the ventilator in side elevation.

In the arrangement shown, thel cowl l0 is formed with a channel l2 surroundingr` the ventilator opening .closed by thetop 14 of the ventilator. The top 114 is carried by a pressed metal part 16 across the back of which is a bar l8 secured to, or integralwith, arms 20'at rits ends. Arms 2() are pivoted at 22 on ystationarysupports 24 secured by bolts or screws 26 to the bottom vofthe side portions of channel V12. Only one of the arms '20and one of the supports 24 appear lin the drawings. w EX'- ceptY as vfurther describedl below, these Vparts maybe of any desiredjconstruction. n

The one ofthe supports 24 which ap- `pearsin the drawings is provided with a ratchet part 28, any tooth of which may be engaged by the end 30 of apawl Vor plunger 32, Pawl 32 is guided by end 30 sliding in a slot in arm 20, and by a stud llcarried by arm 20 a` slot 36 in .the pawl. toward the ratchet by( gaging pins 40 on arm-k 20.

The ventilator is operated by a handle 42 pivoted on stud 34,`which engages, after a certain amount of lostmotion, one or the other of two spaced lugs 44 bent inwardly from arm 20 on opposite sides of arm 42. During this lost motion, pawl 32 is withand passing through The Vpawl is urged [ber rigidly a leaf. spring 38 ,en-k

drawn against the resistance of spring 38 by engagement of one orA the other of two cam shoulders 4G with one of two shoulders 48 formed on the pawl. For convenf ience of manufact-ure, shoulders 46 (also shoulders V48) are made as a continuous ledgeextending clear across handle 42 (or pawl 32).y The ledge forming shoulders 48 (or 46) may, if desired, be a separate part having a shank set into an opening in the pawl (or handle) proper.

' It will be seen that rocking handle 42 `in either direction first disengages the pawl,

and rthen swings the ventilator. On the release ot the handle, spring 38 causes the pawl to reengage the ratchet.

IVhile one illustrative embodiment of my invention has been described in detail, it is not my intention to limit its scope to that particular embodiment, or otherwise than by theV terms of the appended claims.

I claim: i l. A cowl Vventilator for an automobile comprising' a cowl having an opening ther in, a ventilatingvclosure for said opening, a support secured to the under side oi said cowl adjacent the opening, a swinging memsecured to the ventilating closure and pivotedto said support, a ratchet on said support,a pawl inovably mounted on said swinging member and yieldingly ei'igaging the ratchet, and an' dle eliective to irst withdraw the pawl from the ratchet and then to close the ven- Vtilating closure.

2. A cowltventilator comprising a cowl having an opening therein, a Ventilating closure Vfor said opening,.a support secured rto the under side of said cowl adjacent the opening', a swinging men'ibei-.rigidly secured lto the `Ventilating closure and pivoted to said support,
