'VENTILATFL Application ied December 10, 1925. Serial No. 74,440.

@ur invention relates to improvements in ventilators for vehicle bodies.

The object is to provide a ventilator for a vehicle body which is so constructed that either the front end or the rear end of the ventilator may be raised to regulate the air admitted through the ventilator opening into the vehicle body in the manner desired.

y. An important advantage is the provision of a. ventilator ina suitable wall portion of a vehicle body, such as the cowl or roof ofy a closed automobile, boat or aeroplane body,

which ventilator is so built and has a closure so mounted that either the front end or the 5 rear end of the lclosure may be tilted upwardly and supported at different elevations in the open position. l

An important advantage of this invention is the fact that ventilation of the car body may be had with a strong draft by opening ventilator toward the front, also ventilation of the car body may be had without any draft by opening ventilator toward the rear.

A. meritorious feature resides-in the conn struction of such a ventilator with a minimum number of parts adapted to be easily and quickly operated and held against rattle at any adjusted open position and which is provided with side wall portions adapted to close the ventilator opening'on the sides at any open position of the ventilator.

The vabove objects and advantages, t0- gether with others of importance and merit, will more fully appear from the following specification, appended ciaims and accompanying drawings, in which:

In Figs. 1 to 10 inclusive of the drawings we have/shown our invention as embodied in a ventilator mounted in the cowl of an autobile body to ventilate the foot space and the interior of the body. In Figs. 11 to 13 we haveshown an embodiment of our invention disposed in a wall portion such as the roof of a vehicle. Obviously our ventilator may be installed at any suitable place in the wall of the body of the vehicle. In automobile practice ventilators are commonly placed either in the cowl or roof of closed bodies.

itis ldesirable that a ventilator be capable of regulation so that the air draft Iaxllmitted through 4the ventilator opening may Ibe controlled to meet the requirement-s and the con dition of the weather. At one time a strong air blast maybe needed while at another t-ime the minimum amount of air movement may be required. Our ventilator is of such a. char acter as to meet these requirements and varimum and minimum amount of air iiow. Through the use of our invention ventilation may be accomplished with or without creating a draft. i f

In Figs. 1 to 10, let 20 indicate the cowl of an automobile body provided withfan instrument board 22 and a dash board 2. The cowl is provided with ajventilator open` ing having a coaming 26 about its margin. A closure 28 isprovided for such opening. This closure hasv a downwardly-extending flange adapted to seat over the coamin 26, The closure is provided with side wal ous intermediate stages between the maxilos portions 31 arcuate in form which extend ownwardly within the opening on opposite sides and serve to close the opening at .the sides at any position ofelevation,

The closure is so supported that either the front end or'the rear end may be elevated. to an open position and mechanism is provided to elevate either the front end or the rear end of the closure and to support sides at both the frontv and rear end. These pivot pins are removably received in notches 34 formed in the coaming 26 so that either the front or the rear end of the closure may be raised, the closure pivoting about the pivot pins at its opposite end.

To elevate the closure we provide an operating member 36 which extends through the instrument board and. is. provided interiorly of the body with a handle 38' and is supported at the opposite end in the dash*l 24 for'endwise movement. A link 40 is piv- 'oted at 42 .to the rear en`d of the lclosure and is provided with a saddle 44 slidably mounted upon'the rod 36. A link 46 is pivoted at 48 to the forward end of the closure and is provided with a saddle 50 slidably mounted upon the rod' 36. lStops 52 are carried by the rod 36, being-positioned beyond the saddles 44 and 5 0. -An expansion coil spring 54 vis carried by the rod 36 interposed between the

saddle members

44 and 50 tohold them n art, as appears in Fig. 1, so as to hold the c osure in the covered position.

'It will be seen that when the operating rod 36 is moved forwardly to the position shown in Fig. 2, the rear end ot the closure will be tilted upwardly. It the operating rod 36 is moved rearwardly beyond the positionshown in Fig. 1, the forward end of the closure would be tilted upwardly. The closure would in each instance pivot about its pivotal connection at the opposite end from the elevated end. The rod 36\, is provided With a plurality of notches 56 adapted to engage over the edge of the opening 58 in the instrument board through winch the rod passes to hold the sameat adjusted positions.

In Figs. 4, 5 and 6 we have illustrated a modified form of our invention in which we employ the pivot pins 32-described in con-v nection with the description of Figs. 1 to 3 and the notches 34 in the coaming also hereabove described 'o servevas pivotal mountings for each end of the closure. To raise and lower the closure we provide different operating mechanism. A pair of brackets 60 are secured to the wall portion of the body, as appears in Figs. 4 and `5, and a spring 62 engages thesebrackets with the adjacent side wall portions'31 ofthe closure, exerting aA downward pull on the closure vto hold it thereof and as the lever is moved in the opposite direction the closure will be rocked to tilt .the rearward end upwardly. This o en position is shown in dotted' outline in ig. 4 and in full outline in Fig. 5,. l

In Figs. 7 ,to 10 we have shown a second modified form of operating mechanism. A link 70 is pivoted at 72 to one side of the closure at one end. A corresponding link (not shown in the drawing) is pivoted to the same end of the closure at the opposite side. Opposite ends of ,these links are pivoted at 74 to the roaming. The closure is provided at the end opposite that to which the link is pivoted with a saddle 76 adapted to seat over a pivot pin mounted in the eoaming. An arm 78 extends downwardly from the closure and is pivoted at its lower end to an operating rod 30. v This operating rod is provided with notches 82 and extends through an instrument board and is adapted to be adjustably moved through the opening therein in the same manner as described in connection with 'the operating rod shown in Figs. 1 to 3.

Anti-rattling springs 84 are'wound about los i the pivot pins 74 and engaged at one end over the link 70 and at the opposite en against the side wall of the body, whilesimilar anti-rattling springs 86 are wound about the pivot'pins 72 and engaged at one end against the closure and at the opposite end againstthe link 70. It will be seen that as the operating member 8O is moved forwardly the forward end of the closure is elevated while if it is moved rearwardly the closure is rocked to elevate the rearward' end. v

Iax Figs. 11 to 13 we have shown a third modilied form of our invention, here illusf trated and used in the roof of a vehicle body. The roofor other side wall portion is 'in V- cated as 88 having a ventilator opening surrounded by a coaming 90 and a closure 28 provided with a marginal flange 30 and side walls 310i the'same character as described in connection with the construction shown in the figures heretofore explained.

JA rotatable cam 92 is pivoted by a. pin 94 to the coaming 90. Thispcam is eccentrically mounted in a side wall portion 31 of the Handles 100 are secured to the under side oi" the closure at each end and when the closure has been raised t0 the position shown in solid line in Fig. 11either one of these handles may be grasped and either end lof the closure pulleddown upon the coaming so as to elevat-eeit-her the front or the'rear end of the closure, the adjusting nuts 96'be'ing loosened and tightened to permit the completion of these operations.

What we claim is:

- 1. In a road vehicle body, -a wall portion provided with a ventilator opening having a surrounding coaming, a closure for said opening provided with a marginal iange adapted to seat over said coaming, a pair of hnks one on each side ot the openlng, each link pivoted at one end therein. and at the opposite end to the closure whereby, the closure may be swung upwardly withsaid links about their pivot or swung upwardly away from the links about its pivotal connection therewith, an arm depending below said closure and an operating lever engaging said arm to swing the same to tilt the closure upwardly from either end,` a spring about the pivot at one end of the link engaging the link and the adjacent side of the opening and a spring about the pivot at the opposite end of the link, engaging the link and the closure.

2. In a road vehicle body, a wall portion provided with a ventilator opening having a surrounding coaming, a closure for said opening provided with a marginal ange adapted to seat over said coaming, a

air of links one on each Vside ot the openingpivoted atv one end therein, each of. said links pivoted .to the opposite end of the closure whereby -such end of the .closure may be swung upwardly thereby, while the opposite and free end of the closure may be swung upwardly, the closure pivoting about its connection with said links, saddie members on the opposite and free end of `the.closure adapted to engage over pivots within the opening when the opposite end of the closure is swung upwardly, an arm depending below the closure substantially intermediate its ends, a lever pivoted to said arm'to swing the same in one direction to tilt one end of the closure upwardly and to swing the same in the opposite direction to tilt the opposite endfof the closurev upwardly.

In testimonywhereof, we sign this specification.
