Patent appiication ser. No.6s,525, led March 12, 1936, I have described a device for fixing window,` glasses, panels, and nat pieces of.

the same kind in a frame or support schas the recess of a window. 'I'he xation device includes August 3, 1931, 'serial No.`15'z,zo9 inname August 8,1936 l toiaims. .lomo-56.4)

Figs. 3 and 4 are a transverse direction with respect to the panel, f

said retainer having its rear portion rigid with the frame'or support and a freely exible front portion provided withl a beaded edge adapted to retain the panel in contact with the backing 'means;,in an embodiment of the said devicethe edges ofthe panel are inserted in `an elasticsheath which is positioned between afprojection or ange on the rabbet orlike part ofthe frame' or support, and a locking frame held in place by the panel retainer.

The object of the present invention is to provide changes and improvements in a device of this kind, especially with a view to facilitating two other embodiments of the invention, respectively; Y

Figs. 5 and-,6 are sectional views, also analogous to Fig.' -1, but vcorresponding to embodiments of the invention in which the retainers are wholly independent. l

- In the diilerent figures of the appended drawing equivalent elements. are designated by the same reference characters, respectively.

'I'he glass pane I' has its edges inserted in a marginal sheath or casing 2 of resilient material,

rubber for instance,Y of U-shaped section, posi-- tioned in a housing provided in therecess 3 of the window. 4This sheath or case 2 is held beftween a wall of the housing and alocking or aux-l iliary 'frame 1 of L-shapedl section. At spaced apart points, on the periphery on' the outer side,

frame 1 has projections or lugs I of rectangular section, which are formed to protrudeby a pres' determined amount on the auxiliary or locking removal of the panel or similar part from the` frame or support.

- According to an essential feature of the present invention, the retainer is attached to the locking or auxiliary frame, or even is wholly independ ent thereon, instead of being attached to the support or frame. When the retainer is made as a wholly independent element, itis resiiiently dis- A torted in order to be snapped into position and it is maintained in final position by reason of its own resiliency.

frame. Lugs -1 are planed on their outerv faces vthrough which .they are in contact with the wall l ofthe chousing of the window recess which is at right angles to the wall against which sheath 2 is directly applied. l

Furthermore, accordingto another feature of the vpresent invention, I provide notches or recesses in the elements of the device so as to enable introducing a tool for bending or disengaging the retainer and this facilitating withdrawal of the locking or auxiliary frame. Y

Other features. of the present invention will resultfrom the following detailed description of some specific embodiments thereof.v

Preferred' embodiments of, the present invention will be hereinafter described, with reference to the accompanying drawing, given merely by way of example, and in whichr' 1113.51 is a sectional view 'of a glass pane po`rtioniixed in a window frame by means of a de- On the side of the frame that carries the lugs 1' there are fixed, for instance by means of rivets. elastic tongues 5, constitutingthe pane retainers.

The hook-shaped freeend 6' of the Vtongues en gages a groove la provided in wall 4 as shown.

In view of the shape above described, the supporting lugs 1' hold the frame in an accurate po'- sition inthe window recess and, owing to the provision of such lugs, the iinal trimming or nishing of the locking frame is expeditive since only a small number of.narrow surfaces, viz the bear- A ing surfaces of the lugs, has to be machined.

Rivets or like fastening means for attaching the retainer to the locking iframeA are preferably vice made according to au embodiment of the present invention, this section being made in a plane at right angles' to the general plane .of the glass pane, on the line I-I of Fig. 2

Fig.'2 is a sectional view at right angles to the view of Fig. 1 and made along the broken line positioned where the lugs project from said frame as shown. By reason of the clearances between lugs 1?. atool such as a screw-driver maybe inserted between the retainer 5 and the wall 4, for

bending the retainer toward the Jframe and dis-v engaging, its hook from groove la, whereupon the auxiliary frame can be removed from the window recess.

In the embodiment Iof viding a recess la in the bottom of thev housing,

I-provide relatively wide cavities or notches 4b in the front part of said housing, near the 'outer side of the window recess, and I dispose 'the retainers 5 in an inverse position as compared with that rig.' 3, ,instead vor pm they occupy in the embodiment of Fig. l, each oi said retainers bearing against a shoulder Ic provided on the edge of the corresponding notch. With this arrangement, it is easy to vinsert a hook-shaped tool behind the retainer so as to disengage it by pulling in the direction of arrow C.

I may also provide in the window structure inclined holes II which open behind the tongues and enable of pushing said tongues from behind. in the direction of arrow D, by means of any suitable tool or rod. f course, in this case, the

above mentioned notches are unnecessary.

On Fig. 4, I have shown another embodimentof the elastic retainer; the retainer is longer and is folded back at 5a' then bent into a hooked edge adapted for engagementv with a lip 0r abutment 4c projecting on the outer margin oi' groove lb; in the example shown on Fig. 4, the locking frame I has a relatively less thickness, as compared to the depth of the window recess, than in the instance of Fig. 3. For removing the glass pane. it suilices to lift the retainer by means of any flat tool which'isintroduced into the folded portion 5a of the retainer, so as to disengage its hooked edge from the-abutment 4c.

Figs. 5 and-6 show embodiments of the invention in which the retainers are no longer ilxed to the window recess or the frame but are wholly independent and are held in position merely by .their own elasticity which, so `to speak, keeps them caught as a consequence of their shape.

In the embodiment of Fig. 5, the rear edge of the retainer is bent 'and forms a hook which engages a groove I2 provided in the bottom part of the housing of the window recess behind a heel or rib I3 -provided `in the lateral wall 4 of the window recess. The retainer, which is slightly curved or bent, bears at two points, on the one hand on heel I3, andlon the other hand near the outer edge-of wall 4. The front edge of said retainer' is folded back at 'Ib over the body of said retainerdtself and the end. of this folded portion is slightly bent ,upwardly So as to come in front of lthe front face of the auxiliary or locking frame I and to hold itin position while compressing sheath l2 against the bottom of the housing of the window recess. The retainer is thus-kept applied against heel I3 by the frame 'I itself. For removing-the pane, it is only necessary to depress the retainer at I4 in the direction of arrow E so asV to clear the auxiliary frame l from the holding edge of the retainer, wherestationaryrear'abutment for said pane, substantially parallel with the plane of the pane, having a front projection deiininga back groove between the rear flange and said projection; a removable front abutment for said pane, also substantially parallel with 'the plane of the pane; and a resilient retainer substantially comprising three integral portions, a front portion attached' to the movable front abutment, a but slightly f bowed intermediate portion positioned in a plane substantially at right angles to the plane of the pane and a rear portion in the form of a hookA removably engaging said groove, the retainer being adapted in operation to be stressed to tension between the front abutment and the groove. 2. In a holder for a pane, the combination of a main frame having a front recess denning a rear abutment for the pane, and a rear groove at the back part of said recess; a locking frame forming a frontabutment for the pane dimensioned to be placed with-marginal clearance in the recess, and having marginal projecting lugs constructed and arranged to ilt snugly into the recess;- and at least one resilient retainer, posi-f tioned in the recess along the marginal portion of the locking frame in a plane substantially at right angles to the pane, the retainer being at- 1 tached to the locking'frame solely through its front portion while the rear portion forms a freely deiiectible flap having a back hook adapt- 4ed to engage the' said groove and the intermediate portion of said retainer being but slightly bowed and positioned in a plane substantially at right angles to the general piane of said frames.
