Application filed February 10, 1913. Serial No. 747,398;

To all whom it may concern:

Be it known that I, DANIEL J. MURNANE, a citizen of the United States, residing at St; Louis, Missouri, have invented a certain new and useful Improvement in Window Structures, of which the following is av fail, clear, and exact description, such as will'enable others skilled in the art to which it appertains to make and use the same.

This invention relates to store-fronts and show-window structures of the type in which the outside glass clamping member consists of a piece of hollow sheet metal molding that is arranged in engagement with the glass and with a forwardly pro ecting portion of the stationary frame in which the glass-is set.

The main object of my present invention is'to provide an inexpensive structure of the character referred to which is so designed that the outside glass-clamping member will remain in snug engagement with the glass and with the forwardly projecting portion of the stationary glass-[supporting frame and thusinsure a tight joint between these parts.

Another object is to provide a structure of the character described'that comprises a hollow sheet metal outside glass clamping member, fastening devices passing through the lower portion of said member at approximately right anglesto the plane in which'th'e glass lies, and means for prevent ing said glass-clamping member frcm tilting or moving into an angular position with relation to the glass and the stationary frame when said fasteningdevices are tightened."

Another object is to provide a structure of the character just described in which the means that prevents the glass-clamping member from tilting comprises a portion that reinforces and strengthens the hollow sheet metal outside glass-clamping member.

Other objects and desirable features of my invention will be hereinafter pointed out.

Figure l is a perspective View of a window structureembodying my invention; Fig. 2 is a front elevational view partly broken away of theparts shown in Fig. '1, Fig-3 is a cross sectional view'illustrat-ing' designates a stationary glasssupporting frame, B designates a sheet of glass that is arranged therein, and C designates the outside glass-clamping member which presses the glass inwardly and holdsit in engagement with a shoulder or abutment 1 on the frame A. Said frame isprovided with a forwardly projecting portion 2' on which the clamping member C bears, and means which preferably consists of screw-threaded fastening devices 3, are provided for securely connecting the clamping member G to the frame A. The outside glass-clamping member C consists of a piece of hollow sheet metal molding of any preferred cross sectional shape, and the fastening devices 3 pass transversely through the lower portion of said molding at approximately .right angles to the vertical plane in which the glass lies. The clamping member C herein shown is provided with a flat base portion 4 that bears upon the forwardly projecting portion of the frame A and an inverted channel-shaped portion 5 whose inner leg hears against the front face of the glass, but I i it to be understood that my invennot limited to a structure having an S.-"l aul shape herein shown for the par ticular design of the clamping member C is immaterial so far asmy broad idea is concerned.

It 1S necessary that the fastening devices 3 pass through the lower portion of the clamping member C so that they will clear the glass, and in view of the fact that said fastening devices pass through the clamping member C at a. point below the neutral horizontal EIXlS'Of said clamping member, there e glass-clamping member of the cross- ,base flange 4: of the clamping member 0 is a tendency for the clamping member C to cant or assume an angular position with relation to the glass and to the forwardly projecting portion 2 of the frame A when the fasteningdevices 3 are being tightened and thus prevent the portions 4 and 5 of the member 0 from hearing evenly upon the frame A and the glass B, respectively. In other words, when the fastening devices 3 are being tightened the heads of same bear upon the front face of the clamping member C and exert such a great inward pulling force on the lower portion of the clamping member C that the base portion 4: of said member tilts upwardly away from the frame A and the upper edge of the portion 5 of said clamping member tilts outwardly away from the glass. This, of course, destroys the tight joint between the clamping member and the glass and the frame, and it also causes the lower edge ofthe inner leg of the inverted channel-shaped part 50f the clamping member C to exert undue pressure on the glass and very often results in breaking of the glass. In order to overcome this tendency of the outside clamping member C to cant orvmove out of snug engagement with the glass and with the forwardly projecting portion 2 of the glass-supporting frame when the fastening devices 3 are tightened, I have provided the clamping member 0 with means that cooperates with the fasten-- ing devices and with the base portion 4 of said clamping member to prevent said base P01131011 from tiltmg or moving upwardly away from its cooperating surface on the stationary frame A when the fastening devices pull the clamping member C inwardly toward the glass. The means that I prefer touse for this purpose consists of a reinforcing device D arranged inside of the hol-' low clamping member C and provided with a substantially L-shaped portion whose ver-' tical leg 6 is provided with openings 7, preferably elongated slots as shown in Fig. 2,

through which the fastening devices 3 pass,

the device D either consisting of one long member or a plurality of short members, spaced. apart at intervals throughout the length of the outside clamping member. The L-shaped portion of the device D is arranged in the manner shown in Fig. 1, the horizontally-disposed part lying upon the and the vertical leg 6 projecting upwardly fromthe inner end of said base flange. In

view of the fact that the fastening devices 3 pass through the vertical leg of the device D said leg cooperates with the fastening devices 3 to effectively prevent the base flange 4 of the clamping member C from tilting upwardly when the fastening devices are tightened, theportion of the leg-6 that lies between the under side of the screws 3 and the base flange 4: acting as a stop or abut ment that securely holds said base flange in proper position. -Gonsequently, when the straight line and thus causethe portions 4 and 5 ofsaid member to ,remainin snug en-igagement with the frame and with the glass, respectively.

Thedevice D is preferably provided with curved portion 8 that projects upwardly into the inverted channel-shaped part 5 of the clamping member C and thus reinforces and strengthens said portion, thereby make ing it practicableto form the outside-glass- 1 clamping member I C fromcomparatively thin sheet metal.

Insteadof arranginga device'D inside; of;-

the clamping member C, as shown in-*-Fig. 1, V r

the base flange of the member Qcould be";

projecting tongue ,or tongues that would ,1: strike against the under side, of the fastening devices 3 and thus overcome, any tendency of the member C totiltwhen the fas- V j tening devices 3 are tightened, said tongue or tongues eitherbeing formed integral'with 1 said base flange or formed onpra "separate, Y part 'QriVeted or secured in any othermaa; 1;; 7

provided at its inner edge with an upwardly ner to the base flange .43 of the outside glas s clamping member, as showninFig. 3. A structure of the character abovede-l scribed is inexpensive to manufacture, it can-j I be installed quickly and easily, land as it comprises a means that prevents theloutside clampingfmember C from tilting when-it is. being drawnlintoengagement with the glass,- the liability .of breaking the glass by undue 1 i pressure of the clampingmember is reduced to a minimum, and a tight oint between the clamping member and the'gla-ss and-between the clampingmember .and' theforwardly pro ecting-portion ofthe stationary frame A is always insured;

Instead of having the glassbear against I an abutment .1 on the stationary glass-sup;

porting frame, as shown? in Fig. 1, aniinsideg? clamping member E can be arranged be- ;i-

tween the glass; and the abutment l on the frame, as shownin Fig 4,, 5 d 6 f ey drawings. herein shown is of novel 'design and'isso The inside clamping member constructed thatit cooperates with the glass to form a gutter'for collecting the water that drains down the inner face 'of the glass, A As shown in Fig. A of thedrawings the in-' v side glass-clamping member Ecomprises a 1 V vertically disposed portionlO arranged ,in

front of the abutment 1 on the frameqAQ; a i

and provided at its-upper edge with a for Y wardly projecting flange 11; The "flange 11.

inclines. downwardly slightly toward-the glass so as to form the bottom of agutter qwhose cooperating verticalwall is formed by the inner face'of the glass B. The front edge of the inclined flange 11 is preferably provided with a depending lip 12 which bears against the inside face of the glass, and at intervals the lip 12 is pressed inwardly so as to form drain openings 16 through which the water escapes from said gutter, but I wish it to be understood that it is not essential that the drain openings be formed in this exact manner as they could be formed in various other ways without departing from the spirit of my invention. The member E is preferably formed from sheet metal, and in order to impart the requisite strength and stiffness to same I employ a number of clips 13 that bear against the rear side of the depending flange 12, said clips being arranged in front of the vertically disposed portion 10 of the member E and being connected to the abutment 1 of the frame A by means of fastening de vices 1%. Each clip 13 is provided at its upper end with a forwardly projecting portion 15 having an upturned flange that bears against the depending lip 12 on the member E, the clips 13 serving as rigid abutments which prevent the lip 12 from yielding when the glass is pressed against same during the operation of setting'the glass. The water that drains through the openings 16 in the top gutter previously described is collected by a bottom gutter arranged below the bottom edge of the glass, as shown in Fig. t, said bottom gutter being preferably formed by the base portion 4 of the outside clamping member C and an upwardly projecting flange 17 on the inner edge of said base portion. In the form of my invention shown in Fig. at the bottom portion 4" of this lower gutter is provided with drain openings 18 through which the water escapes, and in the form of my invention shown in Fig. 6 drain openings 19 are formed in the front portion of the clamping member C adjacent the base portion t of same so that the water can escape from the bottom gutter, as indicated by the arrows in Fig. 6.
