T0 all whom t may concern.'

Be it known that I, VILLIAM W. HENRY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia. and State of Pennsylvania, have invented new and useful Improvements in Ventilators for Locomotive-Cabs, of which the following is a specification. Q

The primary object ofthis invention 1s the provision of a metallic ventilator specifically designed for the cabs of locomotive engines and which may be cheaply constructed and utilize in a great measure ma terial which would otherwise go to Waste.

The invention in its broad aspect aims to devise a ventilator which maybe advantageously applied to cars and vehicles generally and which is free from manually operable fastening means for securing the shutter in the required adjusted position, it being necessary only to operate the shutter it to the required position where it will he secured automatically by novel holding means.

The invention. consists of the novel features, details of construction and combination of arts, which hereinafter will be more particu arly set forth, illustrated in the accompanying drawings, and pointed outin the appended claims.

Referring to the drawings, forming a part.y

of the specification, Figure -1 is a sectional view of the body portion of a locomotive engine provided with a ventilator e1nbodying the invention. Fig. 2 is a longitudinal section of the ventilator on a larger scale on thc line 2-2 of Fig. 3, looking in the direction of the arrows. Fig. 3 is a front view of the ventilator. Fig. 4 is a view similar to Fig. 2 of a modification*` Fig. 5 is a section on the line 5-5 of i i 4, looking in the direction of the arrows. ig. 6 is a detail section on the line 6-6 of Fig. 2, showing the parts on a larger scale. Fig. 7 is a detail perspective view of the operating lever.

Corresponding and like parts are referred to in the following description, and indi.- cated in all the views of the drawings, by the same reference characters.

The numeral 1 designates the roof of a locomotive engine cab, car or vehicle to be equipped with a ventilator embodying -the invention. An opening 2 is formed `in the roof 1 for? the egress of warm and vitiated air. A hood is arranged over the opening Speication of Letters Patent.

`each open end of the hood and itsfendsa 'reach to be grasped Patented Apr. 145;, 191' 2 and'is secured to the roof 1 in any manneiq f I The hood 3, shown in F1gs.'1, 2 VVVand @has its top inclined to the plane of the roo, in such a manner that one end o'ffth to4 rests upon the roof l and is securedjl L as indicated at 1, whereas' the opposie e is spaced from the roof 1, as indicatedat The hood 3 including the Vtop ,andgsidles formed of stout to the roo-f 1 in any substantial ivay Piange 6 is had at the upper edge of the of the hood 3 and is preferably form bending an edge portion ofthe wardly. This flange 6 serves tostrength and stiffen the top of the hood., L w

In the modification shownin Eig 5 the only difference in the forinofe' l.

ventilator is in the construction 1ofpith and in the provision `of duplicatefparts the ends of the hood. Inthisfconstru the hood 3t is open at opposite.endsy .nd the top parallels' the roof l-.

of a pendent flange G. Inasrnuchy as t devices near the ends of the hoofllsfi and'. are substantially the .same a detailed ,l soriptionof one only will be givenland suiiice for a clear understandingof the erating means. A shutterl( is located `ne fianged and apertured to Ireceive"iboltsif.v like fastenings 8 by', means `of ywhiclll.)v shutter is pivotally connected tothe. sides of the hood. The shutter 7 ,chose flanges 9 and 10, whereby` close pints.- had. The flanges 9 and lOconsistQof bers or Wings of Aangle bars-.Whicliffare cured to respectively the top of the hoo and the roof of the cab, car or vehicle. The flange 9 is pendent from the top of the hood. The flange 10 ses from the roof 1 about in line with one end of the opening 2. The flanges 9 and 10 form stops against which the upper and lower edges of the shutter close. The flange 9 in addition to its function of providing a stop also serves to stiifen and strengthen' the to of the hood. An arm 11 projects from tie shutter 7 and receives a lateral stud 12 which is arranged to operate in a. longitudinal slot 13 formed Bash. @ed the top of the hood is reinforced-by .meansw in a member 14 of the operating lever 15,

vfilo ber 14of the operatingvlever is arranged to operate. A plurality of projections 21 ex- 'tend from one of the members ofthe bracket 18 into the space formed between the two members 19 and 20. These projections 21 are made rounding to admit of the member 4 14 of theioperating lever riding thereon when passing from one projection to the other. The projections 21 may be provided in any manner and as shown consist of studs secured to the member 20. The member 14 of the operating lever has a longi tudinal slot 22 into which anyy one of the .projections 21 is adapted to extend, thereby olding the operating leverand the shutter in the located osition.. The member 14 of -the operating ever is held in engagement with the studs by means of the spring ac- I. tion of the members 19` and 20, said menibers moving outwardly when the member 14 is riding upon the projections 21 to clear one of such projections and engage with another of the projections. -Y

'It' is observed that all the essential. parts ,of the ventilator are constructed oi" sheet metal`and the Xtu'res, such as the brackets 17 and 18. and the arm 11, may be :formed of material which usually finds its way to upon the application thereto `of sufficient force and in' the'securing of the operating ,lever in the adjusted position. In'the form o'fventilator illustrated in Fig. 4 the shut- 'ter atene end of the hood is closed and I fthe shutterat the4 opposite end may be opened and 'vice versa accordingtfto-the diraction of ltravel of the car. j

From the foregoing description, taken in Aconnection with the accompanying drawings, the advantages of the construction and of the method of operation Will be readily apparent to those skilled in the art to which the invention appertains, and while I'have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is

1. A ventilator comprising a hood having an edge portion of its top bent to form a reinforcing flange, av shutter -pivoted between the sides of the hood, anges at the top and the bottom of the hood for the. shutter to close against, an oberatinglever for moving the shutter, a bracket secured to the hood and comprising spaced members be tween which the operating lever passes, and

a plurality of-projections extending from one of the members of the bracket to engage the operating lever and hold it and the shut-l ter in the adjusted position.

2. A ventilator comprising a hood, a shutter pivotally connected at its ends to the sides of the hood, an operating lever co1nprising a member having a longitudinal slot, means having lconnection with the shutter and arranged to operate in the slotted portion of the operating lever, a bracket secured tothe hood and comprising spaced spring members between which a slotted portion of the operating member passes, and a plurality of projections 'ext-ending from one of the members of the bracket to engage ter in 'the located position.

In testimony whereof I aliix my signature the operating lever to hold it and theshut-
