The present invention relates to a window sash and has for its principal object to pro vicle a structure formed of all metal parts sons to be fire proof, strong, and durable,

"Figure 3" is a fragmentary rear elevation rigid, thoroughly efficient and a reliable in use, relatively inexpensive to manufacture, easy to assemble, and otherwise well adapted to the purpose ''for which it is designed. "With the above andnumerous other objects' in view as will appear asthe description proceeds, the invention residesin certainnovel'features of'construction, and in the combination and arrangement of parts as well'be hereinafter more fully described and claimed; In the drawings i I v 7 Figure 1 is a fragmentary frontielevation of the sash embodyingthefeatures of my invention,

' t Figure 7 is' a'jdetail perspectiveview of one of the corner pieces, and s Figure 8 is a fragmentary detail perspec- .,tive of one of the'pointer strips.

Referring to the-drawingin detail it will be seen 'thzitthe' letters l'Aqdenote generally the'top, bottom; and side rails of thesash, while the letter B denOtesthe cross joint between the side rails for connecting the panesof glass The rails are disposed to form a rectangular sash and are of the 'same construction as far. as. the essence of the ,invention is concerned varying only as to directed to the bottom rail shown in Figure 7 their 'lengthQ-and it is thought that a detail description one. of the, rails will suflice for all. I

Referring. therefore. to one of the rails in -detail it will be seen that itis formed from a single .strip rof sheet metal material which is'bent along certain parallelspaced longitudinal. dimensions, In this detail description of asingle rail particular attention is I2. ,The outer plate 5 of thisrail merges at its inner edge into the inner plate 6 whichmerges into a portion overlying the plate 6 a vertical longitudinal section tor-a distance as, is indicated at-7fand merging into a portion8: which overlies theportion 7 in spaced parallelism thereto, the 'porj of the plate 5 is curved downwardly as at 12-and1merges into a portion 13 disposed at an obtuse angle respect to the outer surface of the outer plate 5. Thispor-tion ion.

13Imerges into an ,overlapping portion 14.- which n turn mergesinto an inwardly extending out-er plate 15 disposed at'right angles to the plate. 5 and win parallelism to the plate 6, and at right'anglesto the :plate 9. This outer plate merges into a portion 16 disposedobtuselyto th e inner surface of the outer plate 15 which merges-into an overlapping portion 17 This'portion 17 merges into an overlapping spaced parallel portion .l8 fo'rming with the portion 17 a pocket for receiving the tongue, terminals 11'. The rails Aare held together by means of corner pieces 19.-one'ot which isshown in detail in Figure 7 and the position therelongitudinal dimensions 20 and 21 to form an'intermediate body portion22. having at one edge an obtuse "exte'nsion23 and atsitfs' other edge an acute extension 24- Theobv .tuse extension, 23 is adapted tobe rece1ved in the, pocket formed by overlying portions 7 and 8, while' the acute'extens'ion 24-fis adaptedito engage tliepane C. Putty or like packing material is adapted to .beplaced beof is indicated in dotted lines in Figure,.3.- The letters 1) denote pointer strips which are vformed of sheet metal bentalong-the tween the portions 10 and 17 and the'adjacentportion of the paneG'as is indicated in Figure 2. a It is to be'not-ed thatt'here is a slight difference between the side and top rails and the bottom rails which maybe ascertained by referring particularly to Figure 2 wherein'it will be seen that the portions '13 and 14bit the bottom rail are dis whereas in the top rail and in the side. rails these portions 13 and 14; are disposed at right angles to the plate 5 andrin parallelism with. plate 15.

.105 posed obtusely to'the plates 5 and15 and The joint cross'piece B'includes generally three members shown respectively in'TFigures 4,15 and 6. The member shown in Figure 4: is in the inside member, and 1s formed "from a single sheet of metal bent along parallel longitudinaldimensions 26 and 27 to provide an intermedlate plate portion 28 merging at its edges into obtuse extensions 7 '29 each of which is bent inwardly over upon itself as at 30, The member shown in Figure is bent along spaced parallel longitudinal dimensions 31 to form a center strip plate 32 vvhich merges into obtuse extenv sions 33 which are bentover upon themselves to form u shapedextensions 34 that provide pockets. The member shown in Figure 6 is bent along spaced parallel longi tudinal dimensions 35 to provide a center strip 36,which merges at its edges into acutely disposed extensions 87 adapted to be received in pockets 34 as is clearly shown in Figure 2. Themembers shown in Figures 5 and 6 form'the outside portion of the joint piece, while the member shown in Figure 4 forms the inside piece thereof. Screws 38 q pierce openings 39 in the'plate portion 28 and pierce'the strip "plate 36. Packing such as puttyor the like may be interposed betweenthe two panes'which are held in place I claim as new and by these joint members as clearly shown in Figure 2. i i v g i j All parts of this window sash are formed fromlsheet metal bent in the manner described. The sash thus formed is fire proof,

strong, durable, and rigid, and will therefore prove thoroughly efficient and reliable in use. It is thought that the constructio'n, utility, and advantages of the all metal .sash willnow be clearly understood without amore detail description thereof. It is to I be understood, of course, that the joints of the various rails and cross joint pieces may be soldered together in the well known manneriv The'present embodiment of the invention has beendisclosed in detail merely by wayof example since in actual practice it at-- "tains the features of advantage enumerated 'a's desirablein the statement of the inven-' -tion, and the above description.

parent that the changes in the details of construction, and in the combination and arrangement of parts may be resorted to with out departing from the spirit or scope of the invention as hereinafter claimed or sacri- :ficing any of its advantages.

"Having thus described my invention, what desire to secure by Letters Patent is 1. A window sash'of the class described l including aplura-lity of rails, each rail being formed'from a single sheet of metal bent alongp'arallel spaced longitudinal dimen "sions to, form ahollow construction having an outer plate merging at'its inner edge into a right angularly extending inside plate.

which merges into an overlapping portion It is apthat is bent over upon itself and merges nto an. inner plate disposed in parallelism with the. outer plate and at right angles to the inside plate,-said inner plate merging into an inwardly directed right angular extension merging into an outwardly disposed acutely extending tongue, the outer edge of the outer plate merging into an overlapping extension which in turn merges into an outside plate extending perpendicularly to the outer plate and merging into an obtuse extension overlapping itself and having a spaced overlapping portion for forming'a pocket to receive the tongue I 2. A window sash of the class described including a plurality of rails, each rail being formed from a single sheet of-metal bent along parallel spaced longitudinal dimensions to form a hollow construction having an outer plate merging at its inner edge into a right'angularly extendinginside plate which merges into an overlapping portion that is bent over upon itselfand merges into an inner plate disposed in parallelism with the outer plate and at rightpangles'to the inside plate, said inner plate merging into an inwardly directed right angular" extension merging into an outwardly disposed acutely extending tongue, theouter. edge'of the outer plate merging into an overlappingextension which in turn merges into an outside plate extending perpendicularly to the outer plate and merging into an obtuse extension overlapping itself and having a" spaced over- .plate having obtuse extensions merging into inwardly disposed U-shaped portions to form pockets, the other outside member being formed from asingle sheet of metal bent to provide a center plate and edge acute extensions receivable in the pockets, said inner member being formed from a single sheet of metal bent to provide a center plate having obtuse extensionsbent inwardly over upon themselves. r
