said window to any desired elevation and thelatching of the window at such point, the latching means being largely concealed within the sash and also being adapted to form a corner fastening or corner reinforcement of the sash. The invention also includes certain features of construction which particularly adapt the same for use upon automobile busses, street cars and the like.

The invention also includes a sash formed of; extruded metal strips, preferably of alu- .minum or aluminum alloy, said strips being for most uses of identical cross-section for the side, top and bottom sash members, although where an auxiliary sash is employed,

as in automobile busses or the like, strips of I able.

modified cross-section may. be found desir- The sash members thus formed are preferably provided'with grooves or channelways on the outer and inner lateral sur- 1 faces which. reduces the amount of metal required for the window construction to a minimum and at the same time'causes the frame members to have a finished and artistic appearance, as well as adequate degree of strength for the purpose intended.

The invention also contemplates providing one removable sash member and 1n the preferred constructlon includes the provlsion of separable joints at two corners of the sash and welded joints at the opposite corners thereof, thus providing a rigid thoroughly braced structure and at the same time permitting free access to the glass, permitting its installation orremoval at aminimum of effort and expense. The invention also includes the mitering of the frame members preferably at the upper corners of the win- .dow to permit the fastening thereof by securing members such as machine screws, or

the like, set diagonally through the solid portions of thestrips, a portion of thehead Serial No. 261,435.

of each screw projecting and being. engaged by the rubber buffer strips inserted within the adjacent groove andbeing locked against disengagement from such framemembers.

In addition to simplifying the corner construction of the window,.the use of solid ex-- truded. metal sections of substantially H cross-section with the central portion of greater thickness than the remaining portions of the structure provides a rigid window frame which may be identical in crosssection for both the lateral and top and bottom members, and requiring a minimum quantity of materialand at the same time providing for engagement of the lateral members with grooved guide members and of the top and bottom members with suitably shaped rubber closure strips. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in whichthe principle of the invention may be used.

In said annexed crawing: a

' Fig. 10 is an enlarged detail view partially in section taken along the line 1010 shown in Fig. 6, looking in the direction of the arrows; and Fig. 11 is a perspective view of the latching mechanism.

As is clearly shown in Fig. 1 of the drawing, the window construction comprises a lower sash 1 and an'upper' sash 2 positioned in a suitable opening in a framed structure3. The lower sash is preferably formed of four strips of metal 4, 5, 6, 7, preferably of "extruded aluminum, or suitablesalloysthereof, each strip having a cross-section of H type with the transverse portion of greater thickness than the remaining'elements'and having a depression or groove 8,-centrally of each inner and outer 'face'toreduce the amount of metal in the structure without sacrificing its strength-or detracting from'its appearance Each of'said strips preferably is'mitred at forty-five degree angle at the'respective ends. -Them1tred sections when united are held in right angle relation to eachother-by suitable fastenlng-me'ans. The lower'corners 9, 10, may he -welded, ormay be otherwise secured; A latching device 11 is'pr'eferably secured'to each lower corner and will serveto reenforce the adjacentcorner. The latching devicealone mightserve as the corner fastening but" the corners'are preferably welded "-and 'the latchin device'is a lied thereo ver serving to-further brace'and support the same.

The upp'ercorners =12, 13, are-preferably supplied with removable' securing means, which permits the ready removal'of the top sash member 7 Each upper corneris'preferably secured by means'o'f' a fastening member 14- inserted diagonally -through such corners at the point where the solid "portions '15 of'the strips meet. 'An aperture 16 is formed through thesolid portions of the adj acent strips, such aperture beginning at the base of the groove '17 in the top section, preferably adjacent each of the respective'corners, and extending diagonally through the adjacent ends'of the side strips. The bore to receive the fastenin memberma eXtend com letel b i ingelement. Such element preferably comprises a machine screw 18 having alarge head -19 which projectsslig'htly into the groove 17 for the rubber closure strip 21 at the top of thesash when the corners are securely united. v

' The construction, as has been indicated,

'involvesithe insertion of the glass 22 within thelower window against'the adjacent window frame when lb is in raised orlowered position. The rubber closure strip at the top of the window comprises a flat section 24 to which is united a substantially cylindrical bead 25 secured at one side to said flat section and said bead is forced into secure engagement within the groove of the removablemember of the'window sash,'which, 'as'is-shown, is of somewhatmore than semi-circular eXtentin CIOSS-SQCEIOH. This firm engagement" of the head of the rubber strip within the outer groove of the removable-member provides a direct pressure upon the'proJectmgedge of the diagonal fastening"member-and effectively prevents said fastening'member bey coming loosened through continued vibration of the parts.

A similar strip having a substantially cylindrical bead 26 is engaged within the groove at the lower edge of't'hesash toform" a clothe members are of identical cross section,

the-upper and lower outer. grooves *receiving the rubber closure strips and the outer'l'ater'al grooves being adapted to engage'with the substantially cylindrical beads '28 on the resilient guide members 29- attached'to each v side of the windowkfraine' -and-preferably held by vertical securing strips 80 attached by suitable fastening elements. =Therguide grooves are reamed 'at the corners 'where the 'initred edges overhang.

The upper sash may correspond in structure to the lower and be vertically slidable on guide members, but in constructions-suitable for auto bussesystreet cars and the like, a stationary uppersash is more frequently used.

For an upper sash of this character the metalsections be modified at their outer edges to provide an angle member 31 atthe outer edge ofthe top'andside members 32, '33, 34,-and'a rounded lower edge 'atthe ba'se 36 of the stationary sash, Thisedgeinay have a hollow center 40'tosavemetalg'as is clearly shown in Fig. 2 of the'drawing. P lhe upper sash is preferably secured to the outside of thefra'me'by means of screws orother fastening members engaged throu'gh suitable openings in therespectiveflanges; I I

The corners 'of'the upper sash are secured in substantiallythe same way as in thelowelr '1;

sash, one side, preferably the bottom member, being removable to permit the installation of the glass, which is preferably inserted in the inner groove of the sash member and cushioned with a liner of glazing rubber or similar material. The liner 37 inserted within the inner groove of the lower strip of the upper sash member is preferably provided with an extension flange 38 against which the extension flange 24 of the closure strip is adapted to abut to form a weather-tight seal when the window is closed. Lock washers may be used on the diagonal fastening members when the rubber closure strip is not used in the bottom member of the upper sash.

The upper sash members are also prefer ably formed of extruded aluminum strips, the lateral faces of which are grooved or channeled similar to the sash members of the lower sash to provide for a minimum weight of material as well as an improved appearance without sacrificing any strength in the structure. It will be noted in each construction that the depressed portion of the sides of the sash members are joined with the flanges forming the inner and outer portions of said members upon a radius which meets the solid body portion of such members at points spaced from the base of such flanges to provide adequate strength at such points.

The lower corners of the main sash, as has been indicated, are preferably provided with latch members which form corner reinforcements as well as fastening means. As is clearly shown in Fig. 11 of the drawing, the latch comprises a base plate 41 having a vertical arm 42 adapted to rest in the groove of the adjacent vertical sash member and a horizontal arm 43 adapted to engage the curved portion of the inner sash adjacent the glass. The vertical arm carries a journal 44 for the latch bar 45 which is provided with an upstanding rib 46 forming a shoulder abutting the inner face of said journal. The horizontal arm is provided with a flange 47 forming a lifting member to raise the sash. The base plate is secured by suitable screws to the respective sash members. In line with the journal and the latch bar an aperture is formed in the adjacent vertical sash member to receive a cylindrical locking dog 48 formed integrally with the inner end of the latch bar.

A coiled spring 49 is adapted to be engaged about the central portion of the latch bar between the upstanding rib and the cylindrical locking dog. One end of the spring is adapted to be received in an aperture 51 on the inner face of the locking dog and the other end in an aperture 52 adjacent the journal in the vertical arm of the base plate. A recess 53 provided on the inner face of the vertical arm in alignment with the journal is adapted to form a housing for the spring. The outer end of the latch bar is provided with a tapered head 54 having a ribbed portion 55 over which is engaged a latch release arm 56 havlng an openmg similarly ribbed to engage the same. A set screw 57 engaged in an a erture in the end of a latch bar serves to holc the latch bar, spring,and latch rean arcuate portion 62 which is adapted to engage one of a series of locking apertures 63 formed in the respective vertical guide members of the lower sash.

It will be understood that the arcuate portions of the locking dog are forced outwardly by the coiled spring and engage the adjacent apertures of the lateral guide members to hold the lower sash to any desired position of adjustment. hen it desired to change the position of the lower sash, the release arm of the latches at the respective lower ours of the sash are depressed toward the lifting members and the flat faces of the cylindrical locking dogs are turned to vertical position, and in such position clear the ad jacent guide members, leaving the lower sash free to be adjusted to any desired position.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
