Specification of Letters Patent. Patented Nov. 19,1918.

Application filed March 31, 1917'. seriai'n l 158,937.

ticularly to gas heaters of thewall type, the,

primary object of my invention'being the provision of a guard or deflector hood applicable to heaters of this typeto protect the wall above the heater from damage and to deflect the heat outwardly and down wardly into the'room. t

A still further object of my invention resides'inthe provision of a guard of this character which may be readily applied'to or removed from the heater and which will in noway detract from the appearance ofthe heater when in use.

Vith these and other objects in view, my invention will be more fully described, illustrated'in the accompanying drawing, and then specifically pointedout in the claims which are attached to and form a part of this application.

In the drawing:

Figure 1 is a vertical sectional view taken through a wall heater of the type commonly employed in bathrooms, showing my. invention applied thereto;

Fig. '2 is a perspective view of the guard removed from the heater;

Fig. 3 is, a fragmentary sectional View, showing the guard applied to another form of heater commonly known. as a fireplace heater;

Fig. 4 is a perspective view of the form of guard shown in Fig. 3.,

Corresponding and like parts are referred to in the following description and indicated in-all the views of'the 'drawing by the same reference characters. i

In Fig. 1.1 have illustrated my-invention asapplied to a wall heater'having a casing 10 adapted to be seated in a suitable recess formed ina wall. 11. This casing is covered both within andwithout with asbestospaper -12 or other suitable fireproof material and includes a back wall 13, bottom wall 14, top

wall 15 and side walls 16, the top, bottom and side walls being formed at their free edges with outwardly directed flanges 17 for engagement against the outer face of the .wall' oft'the room and'to receive clamping bolts 18 by means of which a combined perforated face plate and hood 18 of the usual or any preferred type is secured.

back deflectingwall 20 extends from a point adjacent the bottom wall 14 and in spaced'relati'on to the rear wall upwardly and forwardly engaging at its free end upon the upperface of an inwardly directed seatin'g'flangeQl formed'upon the. lower edge of the hood proper of the face plate. The curved" forward face of this wall is covered with asbestos 22 or other suitable material and the space in front. of it constitutes the combustion chamber of the heater. The face'plate19 is providedwith perforations 19 and in spaced relation to its lower end witha transverse brace bar23 to which the burner plate 24 is secured by bolts 24-. and towhich is also secured by the bolts 24:" the forward edge of a lower or bottom deflector plate 25 through which the upper ends of the burner tubes 26 .of any suitable type of burner 27 project. As my present invention relates in'no way to the construction of the heater itself or its burner, the foregoing'd e scription is believed" to 'be' sufli c'ient; It should be noted, however, that the burning gases are deflected outwardly into the room by the deflecting wall 20 and that air is drawn in through the lower portion. of the before it passes through'the perforations '19 at the sides and top of'the face plate or'hood, the deflector plate 20 having side wall portions"26" secured in spaced relation'to the side walls of'the casing or body' of the heater.

My invention comprises a supplemental hood or guard indicated as a whole by the numeral 27 and be's't "shownin Fig-I2 of the drawings. This v parts and "isadapted to be detachably "secured to the'heater; when desired. One part consists of sheet metal orca'stingmade to suitable shape and formed to provide a front wallorflange28 terminating in side wall or "bracket portions 29 substantially triangular in shape and provided at their rear edges with laterally directed attaching flanges 30 adapted to engage against the edge portions of the face plate and to be secured by cerguard is formed in two reason, each flange is provided with a bolt receiving opening 31. The other member of the hood 27 is also formed of sheet metal or casting and consists of a top or cover 32 having its edges secured to'the upper edges of the

portions

28 and 29 of the other part of the hood, as shown at 33 in Fig. 1. The rear edge of this member is provided with an upwardly directed flange 34 having a bolt receiving opening 35 through which one of the bolts 18 may be passed, other of these bolts being passed through the bolt openings 31 of the flanges 30. 1

Obviously, when the above described guard or supplemental hood is in place, all theburnt gases which would otherwise pass upwardly adjacent the wall and possibly injure it are deflected outwardly and downwardly into the room so that the wall is not only protected but a greater heating efficiency is obtained. Furthermore, all of the heated air from'the chamber behind the deflector plate 20, which passes through the upper portion of the hood 19, is deflected forwardly and downwardly in the same manner. In Fig. 3 I have illustrated a somewhat modified modified form of my invention which is applicable to fireplace heaters in which the back wall 36 of the heater casing 37 itself forms a deflector wall and in which the face plate 38 is formed with an imperforate hood 39 pr0jectingsomewhat in ad vance of the plane of the face plate across the front of the heater at the top thereof.

In this form of stove, a short top wall 40 joins the upper end of the forwardly inclined back wall 36 with the lower edgeof the hood 39 and each inner side edge of the faceplate about the combustion chamber is provided with an inwardly directed lug 41. The supplemental hood or guard 42 employed with this form of heater is best shown in Fig. 4 and is formed from a single piece of sheet or cast metal having its forward edge bent down to provide the front wall or flange 43 and its rear edge bent upwardly to provide a retaining flange 44. Its ends are bent downwardly at right'angles to the body and stamped or cast to substantially correspond in shape to the side or bracket portions 29 of the guard previously described, as shown at45; Each side wall or bracket portion 45, at its rear edge, is formed with a notch 46 to engage or seat the uppermost of the lugs 41 and the hood may be detachably supported in place without any fastening means by engaging the flange 44 against the inner face of the lower cross portion of the hood 39 and seating the lugs in the notches 46 of the bracket portions. The operation of this guard is, of course, the same as that of the guard previously de scribed,all burnt gases and heated air be- -is claimed as new is:

1. The combination with a gas heater including a face plate and permanent hood, of a supplemental hood detachably secured to the faceplate and having a top wall of greater width than the permanent hood and disposed at substantially right angles to the face plate and provided at its rear edge with an upstanding attaching flange and at its forward edge with a depending flange, and provided with straight end walls the forward edges of which are inclined downwardly and rearwardly in the direction of the face plate. said supplemental hood serving to direct-the heated gases outwardly and downwardlyinto a room. 7

2. The combination with a fireplace including a body, face plate and permanent hood, the bottom of the hood depending below the top of the body and the face plate being provided at its sides with inwardly directed lugs, of a removable supplemental hood having a top wall of greater width than the permanent hood and end walls, and an upwardly directed flange at the rear edge of the topwall, the rear edges of the end walls being formed with lug receiving notches whereby when the removable hood is positioned with its top bearing against the bottom of the permanent hood and with its upwardly directed flange engaging behind the depending portion of the permanent hood the lugs will engage in the notches of the end walls to support the supplemental hood and still leave it free for immediate removal.

In testimony whereof I aflix my signature.
