VENTILATING WINDOW-BASH. i

Specification of Letters Patent.

Patented Dec. 14%, 1915.

Application filed March 22, 1915. Serial No. 16,191.

To all whom it may concern Be it known that l, Gusrav BENISUH, a citizen of the United States of America, and a resident of the borough of Brooklyn,

county of Kings, and State of New York,

have invented certain new and useful. Im-

provements in Ventilating lVindow-Sashes,

of which the following is a specification.

This invention relates to improvements in and relating to ventilating window sashes, and particularly such sashes for bronze doors and windows of mausoleums or other such structures exposed to the elements, and wherein durability and freedom from lea.

age, together with ventilation, are required.

In such doors as heretofore constructed,

shutters were provided which swung inwardly on hinges and closed against the back of the door, and when opened for ventilation would allow rain to beat into the structure to the detriment of the same, and even when such shutters were'closed, rain would beat in the bottom between the frame and the shutter.

The object of the present invention is to provide a sash forsuch structures which may be readily opened for ventilation or re- :imoved for cleaning, and which when so opened for ventilation or when closed will present no exposed joints to allow rain to beat in.

Another object is to provide such a sash simple in construction and inexpensive to manufacture.

lVith these and other objects in view, my

invention comprises the novel features, ar-

rangement and construction of parts hereinafter more fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the drawings, Figure l is an elevational view of a door embodying my invention with parts broken away; Fig. 2 is a vertical section thereof; Fig. 3 is a vertical section of a slightly modified form of construction;

Fig. 4: is a cross-section taken on the line 1& of Fig. 2; Fig. 5 is a cross-section taken on the line 5-5 of Fig. 3; and Fig. 6 is an enlarged sectional view showing one of the jambs engaged by a portion of the sash.

Similar reference characters indicate corresponding parts throughout the several views.

Referring to the drawings, and more par ticularly to Figs. 1 and 2, the frame for the sash comprises a sill 10, a lintel 11, outer side members 12 andlZ-B, and inner side members let and 15. The front plate 16 of the door is'secured to the front edges of the inner and outer side members, and the rear plate 17 is secured to the rear edges of the inner plates, thereby forming perpendicularly disposed recesses at either side of the frame. An ornamental grill 18 is preferably secured between the outer side members.

The sash comprises front angular members 19 and 20, upper and lower members 21 and secured to the side members and provided with longitudinal grooves into which the plate of glass or the like 23 is fitted, and rear angular members 24 and 25, which are secured to the front angular members by means of screws or the like, after the glass is placed in the grooves. he said front angular members are adapted to abut against the rear edges of the outer side portions 12 and 13 of. the frame, and to slidably engage the recess formed between the outer side portions and the inner side portions, thereby forming a water-tight slidable joint at the sides of the sash. The upper member 21 engages a recess 26 provided at the rear of the lintel. and the lower member 22 is provided with an overhanging portion 27 which engages in front of a setup portion 28 of the sill;

A hinged member 29 is secured between the upper end of the sash and the frame for holding the same in ventilating position, as shown in dotted lines in Fig. 2. If desired, the pin. 30 of the hinged member may be made removable, in which case the sash may be completely removed from the frame.

In the form of construction shown in Fig. 3, the sill extends behind the rear face of the door, and is provided with a set-up portion 31, the bottom of the sash being held between this set-up portion and the frame. It will be seen that in this construction, it is unnecessary to provide a recess in the lintel as the upper edge of the sash abuts against the rear plate of the door, and the outer side members 12 and 18 extend to the rear face of the door.

It will be seen that if the door is not provided with a rear plate, the inner side members 14 and 15 of this frame may be dispensed with.

In Fig. 6 is shown an enlarged detail view of one of the jambs of the frame engaged by the sash. The jamb 13 has an outside surface &0, an inside surface 4L1, and inner andouter faces 42 and 43, the outer face 43 comprising a front wall of the frame and extending outwardly therefrom. The angu ward portion 16 of the frame, thereby forming a snug watertight connection between the sash and the frame.

The operation of my improved sash is as follows :When it is desired to ventilate the structure, the sash is rocked on the sill into open position and is held in place by the hinged member, the sliding joint formed by the front angular members being always closed during this operation. To enable the glass to be cleaned, the sash is first rocked open at the top, and the same is raised until the overhanging portion in the lower part clears the set-up portion of the sill, whereupon the sash may be very readily swung clear of the door and cleaned. Should it be desired, the pin of the hinged member may beremoved and the sash completely removed from the frame. 1

I have illustrated.preferred and satisfactory forms of my invention, but it is obvious-that changes may be made therein within the spirit and scope thereof, as defined in the appended claims.

I claim z- 1. A ventilating window sash comprising a window frame jamb having inner and outer surfaces and a rocking sash at the back of the said jamb having flanges extending forwardly therefrom, engaging the outside of the window frame jamb, and having its inside portions 'slidable on the outer surface of the jamb, and when closed having its main portion abutting against the inner face of the jamb, the said flange adapted to remain in engagement with the said outer surface of the jamb along its entire length during the rocking open of the sash.

2. A ventilating window sash comprising a window frame jamb having inner and outer surfaces, a frame outside of said window frame jamb having an inner surface and a rocking sash at the back of said jamb having flanges extending forwardly therefrom, engaging the outside of the window frame jamb, and having its inside portions slidable on the inner surface of the outside frame, and when closed having its main portion abutting against the inside face of the jamb, the said flange adapted to remain in engagement with the said outer surface of the jamb along its entire length during the rocking open.

3. A ventilating window sash comprising a window frame jamb having inner and outer surfaces, a frame outside of said window frame jamb having an inner surface and a rocking sash at the back of the said jamb', having flanges extending forwardly therefrom, engaging the outside of the window frame jamb, and having its inside portions slidable on the inner surface of the outside frame, and when closed having its main portion abutting against the inside face of the jamb,'the distance between the outer surface of the jamb and the inner surface of the outside frame being substantially equal to the width of the flange of the sash, thereby enabling a snug slidableengagement between the said flange and the said jamb and outside frame, the said flangeii adapted to remain in engagement with the said outer surface of the jamb along its entire length during the rocking open of the sash.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
