W-INDOW' AND WALL VENTILATOR one Kubatzky, st. Louis, Mo. Application July 25, 1923, Serial No. 221,189 I 4 Claims.

The present invention relates toimprovements in window ventilators and more particularly to certain'improvements in window ventilators such as shown in my issued Patents Numbers 1,809,518

. and 1,836,852.

The primary object of the present invention is to provide a ventilator which is adapted to be set in a wall construction such as of brick, glass block, stone, etc.

A further object resides in the improved arrangement for efiecting a weather tight construction when the ventilator is in a closed position.

A further object resides in the novel manner of assembling and retaining the swinging end shields against displacement with. respect to the main frame of the ventilator.

A still further object of the invention is to provide a ventilator of this character which may be easily constructed from sheet metal and embod'ying a relatively small number of parts.

Other objects and advantages of the invention will become apparent duringthe course of the following detailed description, taken in connection, with the accompanying drawings, forming a. part' of this,- specification and. in which drawings Figurev 1 is a plan view; looking at the inner side? of the ventilator shown mounted in a wall, and with portions broken away to illustrate certain details of construction. 7 i V Figure 2 is a vertical section thru the ventilator shown in a closed position.

' Figures? and 8 are enlarged. sections on the respectivelines: in Figure 3.1

Referring to the drawings in detail and'wherein similarreference characters designate corre spending parts thruout the several views, the letter A' maygenerally designate the improved ventilator and B a wall construction of masonry in which the ventilator is mounted. "The ventilator A comprises an open frame I adapted tub closed at its inner side by a swinging ventilating shield. I2, and provided at its outer side with a removableperforated screen I4.

The frame Ii], while not essentially so, is preferably formed of sheet metal and includes a horizontal top wall sheet IS, a sloping bottom wall sheet I6, and two .vertical end wall sheets II suitably secured at their meeting ends into an open rectangular-shaped frame Ill. With parti'cular reference, to Figure 6, the forward portion of the top wall I5 is bent upward at a right angle as at I8 providing a forwardly facing stop shoulder extending thruout the length of the frame. Formed along the upper edge of the shoulder I8 is a top moulding I9. The outer edge of the top wall I5 is turned up to form a combined stiffening flange 20 and an abutment, for

the screen'l l. Y

The inclined bottom wall It forms a cover for a wooden sill 2| which extends between the bottom portions of the end walls I1 and this sill may be securedby suitable fastening elements as at 22 in Figured. Adjacent the forward portion of the wall It the metal is doubled upon itself at two slightly spaced apart points providing upstanding walls or

flanges

23 and 24 forming, av trough 2:5. The vertical wall 23 terminates slightly short of the end walls I! as shown in over the outer edge of the sill-2| and forms an abutment for the screen I4.

Eaehend wall I1 is first bent inward along way to the outer side of each end wall, along the inner vertical end thereof, is a side moulding member 29 and which extend forwardly of the stop flanges 21 .to provide vertical channels 3'0.

. The outer vertical edge of each end wall is bent to-form a flange 3|, and these flanges also form abutments for the screen I4 as shown in Figure 7.

Referring now to the ventilating shield I2, the same comprises a pair of metal end shields 32 and a glass deflecting shield 33. The end shields- 32are formed of sheet metal and are of one piece construction providing a segmental-shaped body portion 34 having 13, convexly arcuated upper edge provided with notches 35. Formed along the outer edge of each body portion 34 is a flange 36, and these flanges, when the end shields are in place in the frame l6, extend toward the end walls Along the inner edge of each end shield, the metal is bent upon itself at slightly spaced points providing

parallel ribs

31 and 38 which form grooves for receiving the end edges of the deflecting shield 33. Formed also along the inner edge of the end shield is an outwardly directed flange 39 which is spaced slightly from the outer face of the end shield and forms a channel 40 for receiving the tongue or flange 26 when the shield I2 is closed. This interfltting of the tongues 28 at each end of the frame, within the channels 40 of the end shields renders the assembly draft proof when the shield is closed as in Figure 4. When the shield is open as in Figures 3 and 5, the flanges 36 will engage the stop flanges 21 and limit inward swinging of the shield to its open position.

Depending from the top wall [5 adjacent the upper end of each stop flange 21 is a lug 4| and these lugs co-act with the tongues 28 to form guides between which the end shields slide during opening and closing movement. As Will be observed in Figuresl and 5, the lugs 4| are ofiset outwardly for a. short distance from the stop flanges 27, toward the outer edge of the frame l6, thus permitting the right angular flanges 36 to he slid between the lugs and stop flanges. Provided at the outer end of the upper arcuate edge of each end shield is a. keeper lug 42, and these lugs co-act with the depending lugs 4| for retaining the end shields in place with the flanges 36 engaging the stop flanges 21. These lugs 42, prior to positioning the end shields in the frame l form a continuation of the flanges 36, and after the end shields are in place, these lugs are bent into the plane of the body portion 34 as in Figure 6 so as to extend beyond the flange 36 and engage the lug 4|.

In constructing the one piece end shields 32, the right angular flange 36 is severed crosswise adjacent its upper end to form the keeper lug 42. After the end shield is slid into place in the frame, the upper portion of the flange which forms the lug 42 is bent for a quarter turn so as to co-act with the lug 4| for retaining the end shields in place. To remove the end shields, the lug 42 may be bent back to the original position aligning with the flange 36, thus allowing the lug 42 to clear the lug 4| In placing the end shields in the frame, the lower portion of the flange 36 is first inserted behind the stop flange 21 and the shield lowered into a position as in Figure 3. The shield is then slid laterally until the tongue 28 aligns with the groove 40. This is made possible by the beveled lower portion of the tongue as shown in dotted line in Figure 3. The lug 42 may then be bent into the plane of the body portion 34, thus retaining the end shield in place. The end shields are retained against lateral movement at their lower portions by the end-s of the trough forming wall 23. The glass shield 33 may then be slid into the groove formed between the

flanges

31 and 38. A knob 50 is provided centrally of the ends of the glass shield for imparting swinging movement to the ventilating shield.

Pivotally mounted upon one of the side mountings 29 is an L-shaped latch providing a handle and a. keeper arm 52. This keeper arm 52 is adapted to engage in the notches 35 of the end shield for retaining the shield in various adshield is fully closed, the keeper arm 52 engages over the inner edge of the end shield as in Figures 1 and 4 to lock the ventilating shield in a closed position.

The screen l4 comprises a frame 53 in which is mounted a wire screening 54 of suitable character. This screen frame 53 engages the flanges formed about the outer edge of the ventilator frame In and each vertical or side rail of the screen frame is provided with a hook 55 adapted to engage in an opening 56 formed in the end walls These openings 56 as shown in Figures 7 and 8 have the metal offset outwardly above the opening and offset inwardly below the opening so as to properly receive the turned end portion of the hook 55.

Referring now to the manner of securing the ventilator in the wall construction, a lintel 60 of any suitable type extends across the upper side of the wall opening. In the example shown the lintel is of .metal. Embedded in the plastic joint of the wall above the lintel 66 is a wooden block 6| for receiving a fastening element, such as a screw or the like 62 passed upwardly thru the top, wall I5 of the ventilator frame. The lintel is provided with an opening thru which the screw 62 passes. Embedded in the plastic joint of the wall below the wooden sill 2| is a wooden block 63 for receiving a fastening element 64 passed downwardly thru the bottom wall 16 of the ventilator frame. Thus the ventilator may be inserted into the wall opening from the inner side of the wall and secured in place by the

fastening elements

62 and 64.

justed open positions. When the ventilating Secured as by cementing or other means to the inner face of the stop shoulder I6 is a sealing strip 10 such as of felt or the like, and against which the upper edge of the glass shield 33 abuts to seal the shield along its upper edge when closed. The inner rib 31 of each end shield is cut away at its upper end to allow the glass shield to engage the sealing strip 10 thruout its length.

Changes in detail may be made to the form of the invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.
