To oll whom may concern:

Be it known that I,GEORGE C. 'Hns'rnin of y Portland, in the county of Multnomah ,and

in thay State of Oregon, have invented a certain'new and useful Improvement in Sash-'f Bars, and do hereby declarethatthe follow-f.' ing is a full, clear, and vexact description thereof, reference being had to vthe accom-y 4panyi'ng drawings ,in which-- Figure 1 isa perspective` view ofa portion of' afwindow equipped with a sashv bar em? bodying my invention, parts of the'barand one of the panes ofglassibeing broken away;

. Fig.y 2 a detailxview in perspective of a clamp 15 that I may use at-the window sill Fig. 3 a

n detail view in vertical( section ofthe clamping means 'at the sill; Fig;- 4 adetailview of the'` bolt Imay use'wth the clampsappliedabove the sill; Fig'.f5 a perspective view, similar to Fig. showing a different construction of the clamp at the window sill.

' The object of my invention is to provide a sash bar forsecuring plates or sheets of O'lass for windows, show cases, etc.l which wiI all-metal, have no screws or astenings acessible from thel outside; easily and quickly assembled and taken down; and strong, but light, and inexpensive `of manufacture, and to these ends,- g ,l

My inventionconsists in the sash bar construction substantially as hereinafter speciv fied and claimed. f v. v T o illustrate my invention I'show it adapted for securing two plates of glass 1 in a window frame, the two plat-es being in the same vertical'plane, but I 'do not limit myself to the glazing of windows, nor `to any particular relation of the plates or panes, as they may be arranged in any angular relation between 90 and 180. On the outer side oi the glass I use a vertical bar or ra1l.2,'iormed of sheet metal bent into curvilinear qorconcavo-conveX shape in cross-section, the concave side being towards the glass andthe sides bearing against the respective `plates on opposite sides of the joint between them. The sides A of the rail or bar are bent or curved inward to t' channel or hook-like formation is produced on each'side the bar or rail for the interlockfl ing engagement ofthe clamping devices I employ. Said clamping devices comprise a 5v5- r'ziembor having a tongue-like part that lies between the two )lates of dass and against Spcification-oiIietteras'12a/cent.v i Appia-ation nea Mayfzv. 19m. saranno. 375.939.

i ,whiehfiheir Opposite edge'sgabut giving ominiv a good'wide bearing, and'on'each side hasa laterally and inwardly' bent flange whose edge enters and engages the' channeled or heele-like side ofthe bar,. or lrail and draws and holds it against the otersurface -of the glass, as hereinafter described. vSaid mem- Aber is made of sheetfinetal, and may, as

shown in Fig. '1, bein one piece, bent into'a T-'sl1ape, the portion 3 corresponding toithe vertical member of the T being formed o'f two parallel sections that pass between the .two

platesof. glass and are joined on'tlievin'ner'v side of the latter and theportions 4 corre'- spondingrto the cross ofthe AT curving giirst'` laterally outward and then inward. 0n the inside of the plates of glass', there is a vertical b'aror rail 5"thalt overlapsboth edges of the plates to as to completely cover the joint between them, 4and horizontal bolt -6 having a T-head in'sidefsaid` portion 3, and having a nut- 7 engaging the .8o

outside of the bar or rail 5, so, that by means bars or rails 2 and 5 are drawn ti htly against the outer and inner sides ofthe pI The inner bar or rail 5 may be flat, or," as shown, dished, or concavo-convex, with its concave side towards the glass.

The tongue-like portion of the clamp need not be formed of two me bers joined togaether, as shown in the upper part of Fig. 1, ut they may be unconnected by any integral piece, as illustrated in the lower part ofr Fig.` 1 and in Fig. 2 they being joined instead by a rivet 7 passing through alining holes in the portions which form the sides of the tongue, which holes are countersunk, as

shown, and there being em loyedin this case :t

lpassing through aihole in' the s aid bar i rai and a hole inthe tongue-l like portion 3 of the Yclamping inemberfis a` ates of glass. l

fastened to the sill, theglassmay be removed y from the rear, or if `the clam next vthe sill is not attached o` the latter, t e glass may be removed fror -the front Without disturbance of the outer or inei;rai'ls",'as the case maybe.

The form of clamp which Iprevfer to use atvv the window sill is illustratedin Fig.'5. 7It comprises a vertical main part and'two vcrti cal flanges 1l that extend in diverging' part, which enga e' the" ormations in the ar or' wardly therefrom, is a single foot 12, which may 'be fastened to the window sill., The

employment of the single foot, and having the relative position shown and described, is of'cspecial advantage, inthat it enables the A4c'la'i'np to be conveniently used on a corner.

It will be understood, of course, that in the .embodiment of my invention illustrated in Y' lf 5, the vert-ical bai' or rail 5 on the inner side of the plates of glass is employed.

By reason of the bending of the edges of the outer rail or bar, as shown and descril'ied, the rail or bar is substantially stiliened 'or strengthened, and, as well, a smooth v lglass-engaging surface is -provided which will 25.

not mar or scratch the g ass, and the bar or 4rail is held securely from lateral movement .by the interlocking engagement of the clamps I,with the curved or bent edges; and said bar isA :I claim isz- I l;.ln a lsash bar, the combination of a member having a. tongue-like portion that or, .rail may be carried in stock and cut to length as required, and this is true also of the inner bar or rail, especially when in a ilat form.

The forms of all the parts of nay sash bar are such as to admit of easy manufacture,

and the clamps may be made comparatively short, and only such a number of them are used as theI weight of the glass requires.

Besides the structural and other advantages which have been mentioned, it will be apparent that the channels or passages .which exist in the sash bar may be very conveniently used for the passage of electric.

wires either leading to lights mounted upon the sash bar, or l'or other purposes.

IIa-ving thus described my invention, what sheet metal bar or rail having grooved or channeled glass-engaging edges, and a clamp of' bent sheet metal comprising tT-shaped passes between the sheets or panes and having llanifes i hat engage t he channels or grooves `in said bm'. and press theglass-engaging edges of the bar against the glass and means for applying ressure to said member.

2. In a sas bar, the combination or" a bar or rail having'grooved or channeled glass-engaging edges, and a clamp comprising a membei with flanges that engage the channels oi' grooves in said bar, and press the glass-cngaging edges of the bar against the glass and having a tongue-like portion that passes between the sheets or panes, said clamp being osheet metal bent to form the anges and tongue-like ortion and a bolt connected to said tongue- 'ke portion.

3. In a sash bar, the combination of a bar or rail having grooved or channeled glass-engaging edges, and a clamp comprising a member having a tongue-like part that lies between the two sheets or panes, and two laterally and inwardly bent flanges whose edges interlock with the respective bar grooves or channels, and press the glass-engaging edges of the bar against the glass and a bolt connectedwitli said tongue-like part.

4. In a sash bar, the combination of a concavo-convex bar having its opposite edges grooved to forni rounded glass-engaging surfaces and grooves or channels, a clamp having a tongue-like part lying between two sheets or panes of glass, and provided with laterally and inwardly bent flanges that interlock with the respective bar grooves or channels, and press the glass-engagin edges of the bar against the glass a secon bar situand' ineens independent of said foot for applying pressureto said member to press the glass-engaging edges of the bar or rail against the glass.

1 1n testimony that I claim the foregoing l have hereunto set my hand.
