SASH AND STORE FRONT CONSTRUCTIONS Patented July 18, 1939 UNITED STATES PATENT OFFICE bey-Owens-Ford Glass Company, Toledo,

Ohio, a corporation of Ohio Application January 7,

14 Claims.

The present invention relates to sash and store front constructions and, in general, has to do with an improved type of metal construction for supporting and holding panes of glass in glazed openings such as, for example, in windows, store fronts, showcases, and the like.

Broadly speaking, the metal sash construction herein provided comprises a stationary section and a movable section adapted to receive and 0 grip a pane of glass therebetween, together with tensioning means for connecting the said sections together and for also effecting the application of the desired pressure upon the glass to secure it in place.

An important object of this invention resides in the provision of improved tensioning means for connecting the stationary and movable sash sections together in such a manner that they will exert a resilient cushioned pressure upon the 20 pane of glass while, at the same time, permitting relative movement between the said sections to take care of vibration and expansion and contraction of the glass and metal sash construction without disturbing the setting of the pane or causing injury thereto.

Another important object of the invention is the provision of novel tensioning means of the above character wherein the pressure exerted by the sash sections for clamping the pane of glass 0 therebetween is transmitted through a plurality of spring devices so that the said sash sections are caused to exert a constant resilient pressure against the pane in an even manner to prevent breakage thereof. 35 A further important object of the invention is the provision of positive stop means to limit adjustment of the tensioning means whereby a substantially predetermined, resilient pressure is applied to the glass and wherein crushing or straining pressures cannot be exerted upon the glass regardless of the skill of the party making the installation. Y

Other objects and advantages of the invention will become more apparent during the course of the following description when taken in connection with the accompanying drawings.

In the drawings wherein like numerals are employed to designate like parts throughout the same:

Fig. 1 is a front elevation of a store front embodying the present invention;

Fig. 2 is a transverse sectional view through one form of metal sash construction embodying the invention;

1938, Serial No. 183,793

Fig. 3 is a similar view of another form of sash construction embodying the invention; and

Figs. 4 and 5 are views similar to Figs. 2 and 3 respectively but showing more clearly the manner of assembling the sash sections.

With reference to Fig. l, the numeral IU designates inits entirety a glazed opening in which is mounted a pane of glass I I supported in the window opening by the metal sash construction I2 arranged at the top, bottom, and sides of said window. As shown, the building may be faced with stone, Vitrolite, or other ornamental slabs or panels I3 to enhance the appearance thereof.

Referring particularly to that form of the invention illustrated in Fig. 2, the metal sash construction I2 is mounted on a wooden sill I4 and secured to a wooden back stop I5 carried upon said sill. The sash construction comprises a rear stationary section I6 and. a movable front section I'I associated with one another to clamp the pane of glass I8 in position therebetween. The rear stationary section I6 includes a vertical back wall I9 which abuts the wooden back stop I5 and is secured thereto by screws 2D. Formed integral with the back wall I9 adjacent its upper end is a forwardly directed gutter portion 2l terminating in a substantially vertical lip 22 engaging the inner face of the pane of glass. I8 while formed integral with the back wall I9,v at the lower end thereof, is a forwardly directed, substantially horizontal base 23 supported upon the sill I4.

The movable front section I'I comprises a face piece 24 provided at its lower end with an inturned flange 25 supported upon the base 23 of stationary section I6 and at its upper end with a downturned lip 26 engaging the outer face of the pane of glass IB opposite the lip 22 of the stationary section. The pane of glass I8 is also adapted to be supported at its lower edge upon a plurality of setting blocks which have not been shown as they are well known in the art.

Formed integral with the base 23 of stationary section IE, intermediate the inner and outer ends thereof, is an upstanding web 2l provided at its upper end with a rearwardly directed flange 28 terminating in a horizontal shoulder or shelf 29. The face piece 24 is provided at the upper end thereof, inwardly of lip 26, with a depending leg 30 formed at its lower end with a foot 3l adapted to engage the horizontal shoulder or shelf 29. It will thus be seen that the movable face piece 24 is supported at its outer end upon the base 23 of stationary section I6 and adjacent its inner end upon the shoulder 29.

The under surface 32 of flange 28 is arcuately curved and cooperates with the arcuately curved upper surface 33 of the base 23 to provide a channel 34 which curves downwardly and forwardly, and which extends the entire length of the stationary section I6. Carried by the face piece 24 are a plurality of spring arms 35 secured at their upper ends between the lip 26 and leg 30, while attached to the lower end of each spring arm is a rigid member 36 adapted to be received in the channel 34. The

opposite surfaces

31 and 38 of the rigid member 36 are curved to correspond to the curvature of the walls 32 and 33 respectively of channel 34. The tensioning or adjusting means for the sash sections comprises a plurality of tightening screws 39 threaded through the gutter portion 2I of rear section I6 and having reduced inner ends 40 which engage the rigid members 36.

To install a pane of glass I8 in an opening to be glazed, the rear section I6 is rst properly secured in place by the screws 20, after which setting blocks are arranged upon the base 23 of said section to support the lower edge of the pane of glass. The front section I1, equipped with the desired number of spring arms 35 and rigid members 36, is then associated with the rear section I6 and, as illustrated in Fig. 4, this is accomplished by first moving the lip 26 into engagement with the outer face of the pane of glass and, at the same time, inserting the rigid members 36 in the channel 34 as indicated in full lines. At this time, the tightening screws 39 will of course be in retracted full line position.

While the front section is held in this position, the tightening screws 39 are threaded inwardly to engage the rigid members 36 and to urge said members forwardly in the channel 34. This forward movement of the rigid members 36 in the channel 34 will act to draw the front section I1 downwardly until the flange 25 thereof engages the base 23 of rear section I6 and the foot 3| abuts the horizontal shoulder 29, as shown in broken lines. Simultaneously, the spring arms 35 will be flexed, thereby causing the lip 26 to be urged toward and maintained in yieldable engagement with the outer face of the pane of glass. This will result in the movable section I1 being firmly held against the glass and yet be permitted to yield in a manner to take care of expansion and contraction and any movements of the glass after it has been set. The insertion of the rigid members 36 into the channel 34 upon assembling of the sash sections is facilitated by the upwardly and rearwardly projecting guide rib 4I formed integral with the base 23 of the rear section.

The shoulder 29 further acts as a positive stop to prevent excessive pressure from being applied to the pane of glass so that the operator is not required to rely on his own judgment for the proper amount of tension to be exerted upon the glass. In other words, when making the installation as explained above, the tightening screws 39 are threaded inwardly until the foot 3| is drawn downwardly to engage the shoulder 29, at which time further movement of the rigid members 36 forwardly in the channel 34 is prevented by the said shoulder so that no further pressure can be exerted upon the glass.

The type of sash construction I2 disclosed in Fig, 3 also comprises generally a rear stationary section 43 and a movable front section 44 between which the pane of glass 45 is adapted to be clamped. The rear section 43 is of trough-like form and comprises a vertical back wall 46, horizontal base 41, and vertical front wall 48. The back wall 46 has formed integral therewith at its upper end a gutter portion 49 terminating in a lip 56 which engages the inner face of the glass. The rear section 43 is secured to the wooden back stop I5 by screws 5I passing through the back wall 46. The base 41 is formed integral with back wall 46 and is supported upon the sill I4 while the front wall 48 is formed integral with base 41 and provided at its upper end with an inturned horizontal flange or shelf 52.

The movable front section 44 comprises a face piece 53 provided at its upper end with a downturned lip 54 engaging the outer face of the pane of glass 45. The front of the face piece 53 is notched adjacent its lower end as indicated at 55 to provide a horizontal shoulder 56 supported upon flange 52. The face piece is provided at the lower end thereof with spaced

portions

51 and 58 between which are secured the upper .ends of a plurality of spring arms 59, carrying at their lower ends the rigid members 66 which are received within a downwardly and forwardly extending, arcuately shaped channel 6l formed between the front wall 48 and an upstanding rib 62 carried by the base 41. The inner surfaces 63 and 64 of the front wall 48 and rib 62 respectively are arcuately curved and the opposite faces 65 and 66 of the rigid members 66 are correspondingly curved to facilitate sliding movement of said rigid members within the channel 6i.

The means for tensioning the

sash sections

43 and 44 comprises a plurality of tightening screws 61 threaded through the gutter portion 49, one screw being provided for each spring arm 59 and the inner reduced end 68 of said screw engaging the respective rigid member upon tightening thereof. The rib 62 can be provided with a plurality of notches 69 through which the inner ends 68 of the screws 61 pass.

In the installation of the sash construction above described, the rear stationary section 43 is first secured to the back stop I5 by screws 5I, after which the pane of glass 45 is placed in position and suitably supported upon spaced setting blocks, not shown, but which are carried by the base 41. The front section 44, equipped with the desired number of spring arms 59 and rigid members 60, is then associated with the rear section 43, and this is done, as shown in Fig. 4, by first moving the lip 54 into engagement with the outer face of the pane of glass and at the same time inserting the rigid members 60 in the channel 6I as indicated in full lines. At this time, the tightening screws 61 will of course be in retracted full line position.

The tightening screws 61 are then threaded inwardly to engage the rigid members B6 and to urge said members forwardly and downwardly in the channel 6I. This movement of the rigid members 69 will serve to draw the front section 44 downwardly until the shoulder 56 engages flange 52 and simultaneously the spring arms 59 will be exed in a manner to cause the lip 54 to be urged toward and maintainedv in yieldable engagement with the outer face of the pane of glass. This will result in the application of spring cushioned pressure upon the glass which will allow for vibration and expansion and contraction. In. this case, the flange 52 acts as a positive stop to prevent excessive pressure from being applied to the pane of glass. Thus, when the shoulder 56 engages flange 52, further downward movement of the front section 44 will be prevented, which in turn prevents further movement of the rigid members 60 forwardly in the channel El so that, as a result, the screws 61 cannot be further tight-v ened to cause the front section to exert excessive pressure upon the glass. l *.7

Thel main parts of the two types of sash constructions herein disclosed are preferably Vof extruded metal capable of being` given the desired contour, i'lnish, etc. while the various parts are also of such construction that they can be easily and quickly assembled on the job. I

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
