ATTRNEYs Patented July 22, 1952 WINDOW -CONSTRUCTION Harold E. Graves, Jr., Akron, Ohio, assignor to Br-own Graves Company, Akron, Ohio, a corporation of Ohio This invention relates to casement windows of the slidin'ghinge type.

In my prior Patents No. 1,973,565 and No. 2,051,638 I have shown windows of this type, and the'present'invention relates to improved featiirs in the hardware employed on windows of the type shown in thesaid patents.

In the aforesaid windowsitlie swinging sashes are easily'in's'ertedor removed by tiltin the sash tojengag or 'disengageup'per and lower, pronged, spring clips'which' carry the hinges, and which clips engage in channels secured to the window frame. There is a tendency for rain water to collect in the lower one of these channels and, therefore, a central, run-off slot 'hasbeen provided. It is one object of. the invention to improvethe hardware, onthe lower" part of'the sash; with especial reference to the"drai age'features. Another object is'to simplify the'manufacture and mounting of the hardware elements associated with the lower sash. Other objects are to'improve the hardware in generaL'to give more posi-, tive engagement of the sash inits mounting, to provide a smoother, more certain action, and to protect the wood of a window sill against the effects of rain water."

These and other ends will'be apparentto'those skilled in the art, from the accompanying specification, as illustrated in the'drawingsin which:

Fig. 12 is a view in perspective of one form of channel member.

In the drawings, the main window frame is indicated by the numeral I, and the swinging casement by the numeral 2. In the structureillustrated, the swinging casement is flanked by two supplementary easements 3, which are perman ently closed.

The swinging casement 2 is provided with facing strips 4 and 4', set in-and-iastened by screws 5"to the outer faces of the upper and lower rails, respectively, of the casement. Referring to the lower part of the casement, the facing strip 4 has, on the hinged end of the casement, an extension 6 which is bent downwardly. and again bent atits'end 8 into parallelism with the lower edgeofthe basement. In the end -8 is secured, as by riveting. a pin 9 having a head -II, and around the pin 9 is wrapped a two-pronged leaf spring I2 (Fig. 6) having a short arm I3 and a long arm I4, the arms being bentinwardly at their ends to facilitate sliding of the spring.

The leaf spring is slidable in a, metal channel secured by a screw I5 in a groove H which is formed by routing the lower sill I8, the groove extending beyond the hinged end of the easement 2, as at I9, to accommodate the hinge pin 9, which is outboard withrespect tocasem'entl.

The upright side walls 20, 2 I of the channel extend from an end wall 22 at the inner end of groove extension IQ for a distance slightly beyond the center of the casement-,-at which location the bottom 23 of the channel'is bent-upward to provide a vertical-wall 24 to the heightof the channel and is then bent into parallelism with the bottom 23 ofthechannel, to form a-facing' plate.

26. Beneath the latter is a strip of wood 2-1, which serves-as a backing, and both plate 26 and strip 21 aresecured to'the sill by a screw IS. AS most clearly seen in Fig. 12, the channel a'ndfacing strip are formed froma single pieceofmaterial Plate 26 and wooden stripi'l-have aligned

bores

28, 29, respectively, which receive,- and anchor,-a pin 3| which is secured inoneend of-a radius-rod 32, the other end of which is pivoted to-the cen tral part of lower facing strip i of the casement, bymeans of arivet33.

A conventional latch 34 is provided on the'free end of theflcasement 2 and it will be seenthat. as the casement is urged outwardly'by'a pressureon its latching end, the. casementfisj constrained to turn about the 'r'ivet33 and; ass. consequence;

the hinge pins 9 move toward the center of the sill, along the channel. Upon closing, the action wall 20, and the bottom of the channel was diagri onal at its end. This permitted run-off of rain water, but the top of the sill, at the'outlet, was" exposed to the effects of the wate By the present construction, theouter wall 2| of the channel is also the shorter Wall, but by the integral construction, the sill, at the run-01f point I for rain water, is covered by the channelbcttom',

this protective covering being extended to the outer edge of the sill by the tab 36 (Fig. which is bent downward from wal12-i of the channel to provide the water exit. 'Thi's'feature,together with; end 22 andriser 24 provide complete. protection of all wooden surfaces on the sill top from the efiects of rain water. I Obviously, the'various joints-may be soldered or brazed. Furthermore, these; advantages arise from the unitary structureof-the channel and facing plate, which is, in itself, a desirable-feature in the matters of manufacture and assembly.

. The combined slidechannel and face plate in the upper part of the window frame is identical with the, loweronei except"v that the cutting and bending of theftab (iii mayibe omitted,'.'sincethe problem of waterdrainage'is'not present.

The hinges and leaf springs aresomewhat dif-, ferent at the ,top and. bottom of the easement. Inall open positionsot the casement, its weight is almost entirely carried b'y the sliding hinge and theradius link 39,. To provide smooth sliding qualities, the weight at the. hingefis lcarrie'd by the head i i. of the hinge pin 9, the lo'weredges of leaf spring arias, l 3, I' lterminating above the head H for purpose." Another reason for thisoifset is the ifaict. that the o f the hinge pinsmust be tilted in the act of inserting them in T the channels. Downwardly bent: extension :6 of the face plated compensates for the thicknessof radius link 32 and ensures that head ii of the hinge pin restson the bottom atall times. I

Another consequence of the necessity for tilting the easement when inserting it in place is that the upper hingepin does not contact the top of its receiving channel. Therefore, the extension 55 of the upper facing plate is straight. Since the upper hinge pin must occupy a position somewhat downwardly of the top of its channel, the leaf spring arms [3, l4" are fashioned so that their top edges are flush with the top of pin head N. This ensures that the leaf spring arms lie within'the channel to-provide maximum surface contacttherewith. v

In Fig. '7 is shown an prising the facing plate for the casement, the radius'link, and thesliding hinge It will be noted that the radius link 32 has a natural, bowed form prior to mounting of the easement. This ensures retention of the pins 3| in the window frame and also minimizes friction between the radius link and the facing plate 5 to which it is pivoted. In order to increasethe strength and permanence of the springfaction'of the bowed radius link, it is ribbed longitudinally at the time the bow'is formed as at '36, so that its'lateral cross-section has the form indicated inFig. 8'.

assembly of the unit com- In Figs. 9 and 10 is shown a modification of the combined, channel and face plate wherein the wooden backing strip 27 may be eliminated. As best seen in Fig. 10, the facing portion 26 has integral, depending

sides

37, 38 which serve to space it from the bottom of the groove in the sill, thus avoiding. the need for thewooden spacer.

While certain,preferrediforms of the device have been shown and described, the invention is not limited thereby, since changes in the size,

shape and arrangement, for instance, of various parts may be resorted to, without departing fromthe spirit or scope of the appended claims.
