4 Claims.

The present invention relates to metalsash and store front constructions and has for its primary object theprovision of novel and'improved means for mounting and retaining .a pane of glass in proper adjusted position.

Another object of the invention is thelprovision of a sash or stor front construction embodying innerand outer glass retaining sections of improved construction and arrangement associated with one another ina novel manner and'having novel means for connecting the said sections together to firmly clamp the'pane of glass in position therebetween.

Another object of ithe invention is the provision of a sash or store front construction of maximum simplicity, ease of "assembly and operation, andembodying clip-members or thelike associated with the outer section and actuated by adjusting means associated with the inner section to efiect'the securing of the pane of glass in place.

A further object of the invention is the provision of improved tensioning means embodying "a plurality of cooperating'clip-members and adjusting members, together with. positive means for preventing further tightening of said adiusting members whensaid clip members-have caused the sash sections to exert a-substantially predetermined clampingpressure upon the glass.

A still further objectof the invention is the provision of improved tensioning meansfor connecting the stationary and movable sash sections togetherin such a manner that they will exert a resilient cushionedpressure upon the pane of glasswhile at-the same time permitting relative movement betweenthe said sections to take care of vibrationsandexpansionand contraction of the glass and metal .sash construction without disturbing the setting of .thelglass or causing injury thereto.

Other objects and advantages of theinvention will become more apparentduring 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: i

Fig-1 is a front elevation illustrating a store front embodying the present invention;

Fig. 2 .isa vertical transverse sectional view through. the metal sash construction provided by the invention and Fig. 3is a similar view showing .a modified form of the invention.

In Fig. 1 ofthe drawings, .the numeral 5 designates in its entirety a glazed opening in which is mounted a sheet or paneof glass 6 supported in the window opening by the metal sash construction 1 arranged at the top, bottom and sides of said window. The front wall of the is building =may be faced withstone, -Vitro1ite, or other ornamental slabs or panels 8.

With reference particularly to Fig. 2, the metal sash construction I is mounted upon a wooden sill 9 infront of a wooden back stop lii which 5 is carried by said sill. The sash construction comprises a stationary rear section it and a movable front section I2 associated with one another to clamp the pane of glass 6 in position therebetween. The rear sash section ll com- 1 prises a vertical back wall l3 which abuts the wooden back stoplfl and is secured thereto by wood screws or the like 14. Formed integral with the back wall l3, adjacent its upper end, is an inwardly directed gutter portion [5 terminatg0 ing in a substantiallyvertical lip l6 engaging the inner face of the pane of glass 6.

The back wall 13 isprovided at its lower end with a forwardly directedhorizontal ledge l1 and formed integral with the outer end thereof is the 25 arcuately shaped bottom wall or baseportion H3. The bottom wall [8 has its upper surface longitudinally grooved or channeled as at l9 to form a cradle portion. Formed integral with the ledge ll, intermediate the front and rear ends thereof, til) is the depending web portion 20 provided with a rearwardly directed wedgeportion 2| cooperating with said ledgeto provide a rearwardly facing, horizontal channel 22.

The bottom wall l8 and wedge portion 2i of 35 the rear section do not contact directly with the wooden sill 9 but instead preferably rest upon a horizontal metal sill plate 23 covering the upper surface of thewooden sill and being suitablysecure-d theretoby screws or the like. The sill plate. 23 may be provided at'its outer end with a downturned flange 24 overlapping othe outer marginal portions ofthe adjacent facing panels 8 and at its opposite end with a vertical upstanding leg- 25 formedat its upper end with a.forwardly directe-dwedge portion 26 snugly received within the channel 22 in the rear sash section. The cooperating wedge portions 21 and 26 form a seal for preventing the seepage of Water and moisture between the metal sash construction and wooden sill and back stop, thereby maintaining the saidsill and back stop perfectlydry and eliminating dry rot, deterioration, and warpage.

The front sash section 12 comprises a face piece 21 having the desired profile and being provided at its upper end with a downturned lip 28 engaging the outer face of the pane of glass 6. The face piece 21 is formed at its lower end with a longitudinally extending, inturned flange 29 fitting beneath the forward upturned end 30 of the cradle portion l8 and having its inner edge 3| arcuately curved to correspond to the curved under side 32 of the said cradle portion.

The downturned glass engaging lip 28 of the front section I2 cooperates with the face piece 21 to provide a recess 33 for receiving the upper ends of a plurality of clip members 34. Each clip member comprises a substantially vertical arm spring 35 bent at its upper end as at 36 and inserted within the recess 33, the end of said bent portion 35 engaging in a notch 31 in said face piece. The opposite or lower end of the spring arm 35 is similarly bent but in the opposite direction as at 38 and carries a rigid body member 39. The body member 39 is formed with a recess 40 within which the lower bent portion 38 of the spring arm is received. The body member is also rockably mounted within the cradle portion 8 of the rear section II and is provided with an arcuately curved bottom surface 4| corresponding to and having sliding contact with the upper arcuately grooved surface I9 of said cradle portion. The contacting surfaces l9 and 4| of the cradle portion I8 and rigid body member 39 respectively are preferably struck in the arc of a circle to afford the requisite seat or bearing for the said body member upon rocking thereof.

The body member 39 is formed, forwardly of the spring arm 35, with an upstanding finger 42 and is likewise provided with a rearwardly extending substantially horizontal lever arm 43 engageable by an adjusting screw 44 which is threaded through the gutter portion I5 of the rear section II. The lever arm 43 is provided with 2. depending lug 45 which is adapted to engage the horizontal ledge |'I upon rocking of the body member 39 within cradle portion I8 and which serves as a positive stop to prevent excessive tightening of the adjusting screw 44.

When installing a pane of glass 6 in an opening to be glazed, the metal sill plate 23 is first properly positioned upon the wooden sill 9 and the rear sash section II is then associated therewith and secured by the screws I4 to the wooden back stop I [I and also by similar screws, if desired, to the wooden sill 9. The pane of glass 6 is then set in place and supported at its lower edge upon a plurality of setting blocks 46 of any desired construction and which are arranged at spaced intervals longitudinally of the rear sash section in the customary manner. After the glass pane has been properly positioned upon the setting blocks, with the rear surface thereof in Contact with the lip I6 of rear section II, the movable front section I2 is properly associated with said rear section. This is done by bringing the inner edge 3| of the flange 29 of said front section into engagement with the curved under side 32 of the cradle portion l8 and the lip 28 thereof in contact with the outer face of the pane of glass.

Prior to the positioning of the movable front section l2, however, a suitable number of clip members 34, are properly associated therewith and when the said front section is associated with the rear section, as explained above, the rigid body members 39 of the clip members 34 will be received within the cradle portion I8 of the rear section I At such time, the clip members will assume the position indicated by the full lines in Fig. 2, with the arcuately curved bottom surfaces 4| of the rigid body members 39 contacting the arcuately grooved upper surface I9 of the cradle portion I8.

The adjusting screws 44 are then tightened to engage the lever arms 43 of the clip members and downward pressure upon said lever arms will cause the rigid body members 39 to be rocked in a clock-wise direction within the cradle portion I8. In other words, as the body members rest or seat upon the upper arcuately grooved surface |9 of the cradle portion, they will turn or fulcrum therein with a knuckle-like action. Upon rocking movement of the rigid body members, the upstanding fingers 42 thereof will act to flex the spring arms 35 in the manner indicated by the broken lines in Fig. 2 whereby to urge the lip 28 of the movable front section into yielding engagement with the glass.

In this way, the movable front section will be maintained in firm clamping engagement with the pane of glass 6 to effectively secure the same in place, while the spring arms 35 will provide for a certain amount of flexibility and resiliency 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. Likewise, the liability of breakage of the glass under severe wind strain and other shocks to which it may be subjected in use will be greately reduced.

The adjusting screws 44 are adapted to be tightened until the lugs 45 on lever arms 43 engage the upper surface of the horizontal ledge I1 whereupon further tightening of the said screws will be prevented. Consequently, the lugs 45 cooperate with the ledge H to provide a positive stop means for preventing overtightening of the adjusting screws 44 and thereby effectively prevent the application of excessive clamping pressure upon the glass which might result in the breakage thereof.

The sash construction illustrated in Fig. 3 is substantially the same as that disclosed in Fig. 2, with the principal difference being in the manner in which the movable front section 41 is associated with the stationary rear section 48.

The rear stationary section 48 includes a vertical back wall 49 which abuts the wooden back stop I and is secured thereto by screws 53. The back wall is provided, adjacent its upper end, with a forwardly directed gutter portion terminating in a. substantially vertical lip 52 engaging the inner face of the pane of glass 5. Formed integral with said back wall at the lower end thereof is a forwardly directed bottom wall 53 supported upon the metal sill plate 23 covering the wooden sill 9.

The bottom wall 53 of the rear section is provided intermediate its front and rear ends with the longitudinally grooved or channeled cradle portion 54 having an arcuately curved upper surface 55. The bottom wall 53 inclines forwardly and upwardly from the cradle portion 54, as shown at 56, and terminates in a substantially horizontal lip 51. Depending from the bottom wall, adjacent its outer end, is a web 53 formed at its lower end with a forwardly directed flange 59. said flange cooperating with said lip to provide an outwardly opening substantially U shaped channel 60 for receiving the lower inturned end 6| of the movable front section 41.

The movable front section 41 comprises a face xiii piece 62 provided at its upper end with a downturned lip 63 engaging the outer face of the pane of glass 5. Carried by the movable front section are a plurality of clip members 64, each comprising a vertical spring arm 65 secured at its upper end to the face piece and having attached to its lower end a rigid body member til.

The body member 65 is rockably mounted within the cradle portion 54 of therear section and is provided with an arcuately curved bottom surface ill corresponding to and having sliding contact with the upper arcuately grooved surface lit of said cradle portion. The body member is also provided with a rearwardly extending lever arm at engage'able by the adjusting screw 69 threaded through the gutter portion 5| of the rear section. The lever arm 68 is provided with a depending lug 'Hl adapted to engage the bottom wall 53 of the rear section upon rocking of the body member 66 within the cradle portion 54 to prevent over-tightening of the adjusting screw 59.

In the operation of this form of the invention, the pane of glass 6 is first properly set in place with respect to the rear stationary section 43 after which the front movable section 4! is associated with the rear section. This is done by slipping the lower inturned end 6| of said front section within the channel and bringing the lip 63 thereof into engagement with the pane of glass. When thus positioned, the rigid body members iii; of clip members 64 will be received within the cradle portion 54 and, upon tightening of the screws 69, the said body members will be rocked in a clockwise direction within said cradle portion to flex the spring arms 65 and urge the lip 63 of the movable front section into yielding engagement with the pane of glass. When the depending lugs 10 engage the bottom wall 53 of the rear section, further tightening of the adjusting screws 69 -will be prevented so as to avoid the application of excessive clamping pressure upon the glass.

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.
