l 1o al! whom it' may concern.'

Be it-lrnowr. that I, TWILLIAM E. `W1NE, a citizen of the 'United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certainv new and useful Improvements in Car Ventilators, of which the following is a specilication.

My invention relates to new and useful improvements in ventilators, and especially to ventilators that are adapted for use on freight cars.

One of the objects of the present invention is to construct a ventilator made up of essentially two side pieces, in which are mounted cross bars in the form of angles, between which are loe-ated shutters, also `formed of angles, the latter being movable so to open and close the vents between 29 the cross bars..

Still another object of the invention is to provide a ventilator -wherein certain lugs hold the cross bars in position while further lugs in the form of tracks guide the movable shutters when operated.

lhen the term angle is used, it refers generally to metal plates that are 1n the 'form of angles, these being readily purchased in the open market, and when arse ranged for use in the ventilators, simply have to be out to length, and in one form out at their both vends to form supporting` projections, as we ventilator.

Still another object of the invention is to provide a ventilator wherein the same may be formed of crossbars and shutters consisting of angular plates, the former iff-'l supported and the latter supported and guided in the two side pieces, in which in turn are cast projections and tracks, so that the ventilator as a whole will be veryk Serial No. 703,170.

economical to make and also cheap to repair, when necessary.

Still another object of the invention is to form a ventilator with shutters and cross bars wherein the shutters may be quickly and easily operated to an open and closed position.

With these and other objects in View, the invention consists in certain new and novel constructions and combination of parts as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of my invention,

F ig. l is a front view of my improved ventilator as applied to the end of a freight car;

liig. 2 is a vertical sectional view showing the shutters in their closed position;

`Fig. 3 is a similar View showing the shutters in the open position;

F ig. l is a detail fragmentary View of the locking dog;

Fig. 4a is a further fragmentary view of the locking means showing the dog in its other extreme position;

Fig. 5 is a detail fragmentary View of one of the side pieces, as shown in Figs. 2- and 3, the shutters being removed for the sake of clearness;

Fig. 6 is a vertical sectional View of the ventilator showing a slightly modified form, the shutters being in their closed position;

lig. 7 is a view similar to Fig. 6, with the shutters moved to their open position;

F ig. 8 is a fragmentary perspective of one end of the movable shutters to show how they are supported;

Fig. 9 is a fragmentary sectional detail.

view taken on line 9-9 of Fig. G; and

Fig. 10 is a View similar to Fig. 5, but showing the modified side pieces as used in the modified forms shown in Figs. 6 and 7. Referring now more in detail to the drawings, Figs. 1 to. 5 inclusive, there is shown the sheathing l of a freight car in which is assembled the ventilator 2 comprising the side pieces 3 and 4, the fixed cross bars 5, the movable shutters 6, the tie bars 7, the operating bar 8, the handle 9 and the dogs l0 pivotally mounted on the bar E).

Riveted to the tie bars a are the metal straps 11 which in turn are secured by rivets 12 to the plurality of movable shutters 6, as may be clearly seen in Fig. 2.

Referring now more specifically to the cross bars 5 and the shutters 6 (and first to the cross bars 5), it will be seen that they each consist of a plate having the legs 13 and 1e, the angle between the legs being ninety degrees, and the depth of each leg being such that it extends nearly across the side pieces 3 and 4, when placed with the apex in the vertical position as shown in Figs. 2 and 3. These plates are readily purchasable in the open market, and of course, may be readily cut to the desired length. They are supported at their opposite ends by the two side pieces 3 and e, as will be referred to shortly. r1`he movable shutters 6 are formed of similar angles, as heretofore mentioned, and riveted thereto are the straps 11, the shutters being arranged so that their one leg will slide along the one leg` of the cross bar when operated, as shown in Figs. 2 and 3.

rlhe arrangement of the tracks and lugs is such that when the shutters are pulled downwardly to a closed position, they will tend to slightly wedge against the adjacent legs of the cross bars as may be seen by comparing Figs. 2 and 3.

Referring now specifically to Fig. 5, there is shown the small t-shaped lug or projection 15 and the lug 16, spaced from the lower leg of the projection 15, the spacing being such that it will receive the leg 13 of the cross bar 5. A further guide or track 17 is shown which is substantially rectangular, with the exception that the fourth side is omitted, and it is to be noted that the lower leg 18 of this track 17 is substantially at an angle of 45 degrees to the edge of the side piece, but the upper leg of the V-shaped lug 15 does not parallel the leg 18, it being in a slight angular relation therewith. rlllie object of having this slight angular relationship is that, when the movable shutters G are moved from their open position, as shown in Fig. 3, to the position as shown in Fig. 2, the one leg of each shutter riding along the upper leg of the il-shape projection 15 will cause the opposite leg of each movable shutter to approach the adjacent leg of each cross bar, and finally contact therewith, to thus slightly wedge the shutters in their closed position and prevent any lateral or loose movement.

As far as the specification has proceeded, it will be understood that the if-shaped projection 15, the lug 16 and the lower leg 18 of the track 17, form a holding means for the one end of the cross bar, while a similar arrangement is provided on the opposite side piece so that the cross bars may be readily assembled and held in the frame. Furthermore, the upper leg of each of the V-shaped projections 15 form a track and support for the shutters as will be readily understood. Any number of cross bars and shutters may be provided for, depending on the height of the side pieces.

For simultaneously moving the shutters, the tie bars 7 are provided, as heretofore referred to; they having a bearing 19 formed in their lower ends through which passes the rod 8.

Referring for a moment to Fig. 2, it will be seen that the rectangular track 17 at the bottom of each side piece, has the base piece 9.0 formed integrally with the lower leg 18 and slightly curved, as at 21 for the reception of the pivotal dog 10. The handle 9 is provided at its one end with the slot 22 and the projecting pins 23 and Q11, while the bar S is provided with the notch 25 as may be seen in Figs. 2, 3 and 1i, so that the handle 9 may be operated either from a downwardly hanging position as shown in Fig. 4, or from an upright position, as shown in Fig. 3, it being simply necessary to engage either the pin 28 or 24C with the notch 25 to rotate the shaft 8 and force it upwardly and inwardly at approximately an angle of forty-tive degrees to open the vents. In other words, move the shutters upwardly and inwardly to open the vents, or close the vents by moving the shutters downwardly and outwardly, in both instances, the dogs 10 travelling along the bases 20, as may beseen in Figs. 2 and B.

The curvature of the bases as at 21, retains the dogs from escaping from the bases, which arrangement of the dogs also provides a locking means for the shutters in their open or close-d positions. V'Vith the ventilator formed in this manner, the shutters and cross bars may be quickly and easily assembled; the shutters may be easily and readily operated to open and close the vents formed by the cross bars, and the shutters may be easily locked in either position. Furthermore, the cooperating tracks, lugs and guides, support the cross bars and shutters and also provide guideways for the movable shutters, and by making one of the lugs at an angle to the other, as above referred to, the shutters when drawn to a closed position, have a slight wedging action, thus assisting in locking the shutters and providing against loose movement or rattle.

A slightly different arrangement of the shutters is shown in Figs. 6 to 10, the principle being the same, but the path of movement of the shutters being a horizontal one rather than a combined upward and inward movement. This is made possible by a slightly diilerent arrangement of tracks 2G which may be understood by referring to Fig. 1()` for the sake of clearness. Each track comprises the angular way 27, the base 28,in

which is provided the depressions 29, and the slightly inclined end 80. A lug 31 is shown parallel to the portion of the track 2T so that a space is provided to receive one end ot' one of the legs of the cross bar 32, this cross bar 32 being similar to the cross bar 13 in the other form.

Projecting downwardly from the center of the portion 28 of the track 26 is a further guide 33 with a leg 34 at right angles thereto, to tightly hold the cross bar 32 in position, the portion also forming a support for one leg of the movable shutter $35. rlhis shutter 35 is similar to the shutter G with the exception that its ends are cut as shown in Fig. S, the portions as at 39 and i0 being cuit away, in each leg of the angle to leave the projections i-l, which projections ride along the bases ot the tracks Z8 and rest in the depressions 29, that is, the center one and the one at the right hand side, or the center one and the one on the left hand side, depending upon whether the shutter is in its open or closed position. In a like manner, these shutters 35 are moved by tie bars 12, and riveted near their ends ai'e the straps 43, which in turn are riveted as at de to the shutter.

This form of ventilator is also quickly and easily assembled. In operation, an inward movement of the bars i2 will cause the shutters to ride along the tracls from the position shown in Fig. 6 to the position shown in Fig. 7, to thereby open the vents, while an outward pull of the bars will cause the movable shutters to travel outwardly and contact along their upper edge with one leg of the cross bars to thereby close the ventilator. l Y

From the foregoing, it will be seen-that the ventilator, whether constructed as shown in the one form or the other, comprises cross bars formed o angle iron and shutters formed of angle iron, which may be easily purchased in the open market. Furthermore, the lug or guides, and projections may be so arranged that the shutters move away and towards the cross bars either in an inclined movement or in a straight inward and outward movement to thereby open and close the vents as the occasion may require. f

Furthermore, an arrangement is shown for easily operating the shutters and for* locking them in either of their two positions. In the several views, I have shown the ventilator as installed in a freight car without any special metal upper and lower rail, but it will be understood that these portions might be used if it is ever desired.

The parts are relatively light in weight, relatively cheap to purchase, and may be readily assembled. At the same time, I have provided a ventilator which will withstand the hard usage incident to railroad installations, and prove highly effective in service.

Many slight changes might be made without in any way departing ironi the spirit and scope of the invention.
