To all whom z'tmay concern.

Be it known that I, HARRY E. CAMrBnLL, a citizen of the United States, residing at New York, in the county of Newv York and State of New York, have invented. a

certain new and useful Improvement in Metal IVindowF'rames and Sashes, of which the following is a specification.

1 slide vertically past each other.

This invention relates to a window frame and sash construction in which the sashes The object of my invention is to make a device in which'positivesealingof the joints between the sashes and the jambs is obtained when thewindow is closed andlin the specific em bodiment of my invention, illustrated in this specification, I accomplish this by causing the final closing movement of the lower sash to wedge both the upper" and lower sashes tightly against jamb members for substantially the height of each sash. Other advantages of my construction will be apparent from the following description.

In the accompanying drawings I Fig. 1 is a front elevation of my windowframe and sashes, showing the lower sash I raised for a short distance. In this figure the following parts are shown broken away, namely: the upper portion of the upper sash and frame, and thelower portion of the rear wall of the jamb on the left hand side of the drawing. A vertical portion of the inner wall of the jamb on the right hand side of the drawing is removed to show the parts otherwise covered! Fig. 2 is an enlarged section on the line 2, 2 of Fig. 1 viewed in the direction of the I arrows 0:, a, of Fig. 1..

Fig. 3 is an enlarged vertical section on ,theline 3, 3of Fig. 1' of the frame and sashes, the lower sash here being shown partly raised. In this figure the upper portion of the upper sash and of the jamb shown is broken away, and a-break is made at b' in order to reduce the height of the figure on the sheet.

Fig. 4 is an enlarged perspectiveview, showing a portion of the middle section 11 of the inner wall of one of the jambs, the.

member J carrying said section, a portion of the lower sash, the lateral sash plates M, N and the inclined projectionsi3 1 and Figs. 5 and 6 are horizontal diagrammatic views similar, to the section shown in Fig.

-2, and are here introduced to show the relinafter described, enter, while the other C:-receives the counterweights' for the sashes. 'For purposes of clearness, said counterweights, together with the suspension chains by which they are connected to the sashes, the lintel and the sash pulleys within said lintel over which said chains pass, are all oniitted since their eneral arrangement Wlll besubstantially t e same as 'shown in my Patent- No. 1,222,357, dated April 10, 1917.

The jamb A, as here shown, is formed of sheet metal and comprises an outer wall D,

a front wall E, a rear wall F and an inner wall G. The inner wall Gi-is made in three sections 10, 11, 12, separated by the vertical'gaps H, I which extend from top to .bottom of said wall. The section 10 of wall G is hooked over'at its rear edge at 13 to receive the bent and hooked over edge 14 of wall F. Section 10 is held in place by a bolt 15 which passes through section 10 and is seated in a lug 16 on the sill 17 The front wall E is of less transverse width than. wall G a1. 1 is flanged at its edge 18, where it is united to the partition or wall 19 which separates the amb' compartments B, C. Said wall 19 extends beyond theja-mbwall E and is bent parallel thereto at 20, and then again bent at a right angle to form section 12 of the inner-wall edges of sections 10 and 12. Said middle section is. supported upon a'barrier member J constructed of sheet metal, as follows:

The front and rear sides are parallel. The. inner side 21 is channeled to receive any suitable packing material 22. In the see-- I pass the as shown at- 27 The otherfl'ange 26 extends beyond wall 19. Within member J may be I in communication with the room.

. rai1'30 of th'e'upper sash at a right angle and then vertically upward at 32. Said vertical portions interlock when i the meeting rails come together. On the packing 28 which bears on wall 19.

K is the upper and L. the lower sashi" Their frames are of sheet metal having meeting rails 29, 30. Asbest shown in Fig' 3, the meeting rail 29 of the lower sash is bent horizontally at a right angle and then vertically'downward at 31. The meeting verticalportion 31 of meeting rail29 is secured a strip 33 of spring (metal which is bent to-enter between the portions 31, 32 when the saidz-meeting rails interlock, and to extend over, the top of portion 32. hen

meeting rails, and so prevents entrance of air or rattling at said joint.

Laterally extendingfrom the sheet metal 'siderails of the sashes, and, as here shown,

made integral therewith, are plates M and N which enter the jambs through the gaps II and I and travel therein when the sashes are moved.

Referring now to Figs. 5 and 6: It will be obvious that in order that the sash plates M, N may be moved freely in the gaps II, I, sufficient clearance must be present. \Vhen the upper sash is seated in closed position, the portion of gap II which is below said sash willbe wholly open to the external air. Said air then entering the compartment B through said open portion of the gap will 'be free to pass through the joint 0, Fig. 5,

between the sash plate M and the edge of middle section 11, and so into the building or room. Clearly, closing the joint 0 will prevent this draft.

\Vhen the lower sash is seated in closed position on the sill, the portion of gap I which ,is.abovesaid sash will be open and External air entering the compartment B atthe joint P between the edge of sash plate N and middle section 11 will then pass into the room through said joint P and thence to the said open portion of gap I. ,Clearly, therefore, closing oint P will prevent this draft.

Now I close both of these joints simultancously by themovement of the lower sash as it reaches its shut or seated position on the sill. Or, in other words, although at all times while the sashes are being raised or lowered, abundant clearance exists in the gaps H, I to permit of the free movement of said sashes, the simple pushing down of are flanges and 26 which bear is bent horizontally I toropens and closes the sashes just as he would any ordinary sashes, and, without any necessary knowlvertically sliding edge of how the result is obtained, causes the proper joints above noted to become closed. I

Referring first to'Fig. done: 7

In the vertical edge of extension plate N 4, this is how it is of the lower sash is an upwardly extending inclined projection 34, here shown as formed by cutting a tongue from the material of said plate. l On the edge of the flange 26 of barrier member J is another but upwardly inclined projection 35, also here formed by cutting a tongue on said edge. The inclined surfaces. of the two projections 34,- 35 both sashes are in closed position, said spring strip closes the joint between the are parallel, and the projection 34 is directly above the projection 35. The parts being in the positions shown in Fig. 5, the clearance then allowing free movement of the plates M, N in the gaps H, I, vwhen the lower sash is moved downwardly to close it and shortly before it reaches its seated position, the projection 34 meets the projection- 35, and as the sash continues its downward movement, two results occur, namely: as the projection 34 rides over the projection 35, the sash plate N is moved toward 'middlc section'll of jamb wall G, Fig. 5, until it closes tightly .thejoint P, Fig. 6. At the same time, the projection 35 is moved by the same means to cause the barrier member J to slide on wall 19, this movement being permitted by the slot and bolt connections of said member J with section 11, as shown at 24. By reason of this movement, the

turned over end 27 of flange 25 acting upon extension plate M of the upper sash forces said extension plate M into contact with section 11, and so closes the joint at O. Both joints O and P are thus closed simultaneously with and by reason of closing movement of the lower sash. I

In practice I prefer to use two pairs of projections 34,- 35, just alike and similarly disposed relatively to one another but located at different heights on the extension plate N, as shown in Fig. 1. The operation of both pairs is simultaneous and the same as has been described with reference tobut one pair. The object is simply to distribute the application of the moving force more uniformly along the elongated parts affected, and since two points determine a line the fact that there are two pairs of projecheight, is drawn against an edge of section Itis to be noted that middle section 11 is :itself loose or floating. Hence it is selfadjusting to the opposing contact pressures of the platesM and N, so that if through any irregularity of construction, for example, one joint or P becomes closed before the other, section .11 beingloose will yield in one direction upon the closing of the first joint, and then will yield in the opposite direction and so readjust itself upon the closing of the second joint. Or, in other words, it finds its own position with respect to the plates M, N bearing against its edges,

in which position both joints. 0 and P will be tight. In windows of this type hitherto made,

the clearance of the sash plates M, N in the gaps H, I has been kept as small aspossible in order to reduce the area of possible air entrance around the closed sashes. But

since, through my present invention, the oints 0, P are always closed when she sashes are shut, said clearance may be made of any desired width, and may even be made- I so that said plates will'be suspended clear of the gap edges. This does away with fricr tional contact at said-edges, permits of the sashes being very easily raised or lowered,

' and if the parts be painted affords ample space for any irregularities of paintsurface; while also protecting the paint from being removed by the rubbing'together of said parts. v

Onlthezsill 17, Fig. 3, is formed a trans- I verse rib 36 of upwardly tapering cross sec- 1 tion.

formed of two sheet metal strips 37 an (i 38. 'The strip 37 on the front side of the rail extends vertically downward below the same, while the strip 38 on the rear side of the rail is bent at a right angle and then "turned downwardly 'at 39.

The channelshaped rail thus formed fits upon the rib 36 when the sash is shut. Hitherto it has been necessary in order to compensate for manufacturing irregularitiesto allow a considerable clearance between the rail and therib, so that even after these parts had become seated there was opportunity for air entrance at the joint. But with the now possible wide clearance-in the gap I and the consequent suspensionof the lower sash therein, as described, it will be obvious that the rail has ample space to swing transto be understood that I. do not limit myself The lower rail of the lower sash is to a jamb thus provided. Vertically sliding window-sashes, as is well known, may have no counterweights and be held in any desired position by means of clamps, bolts, catches or various other analogous devices; and, such sashes may also be arranged in suspension devices whereby they I mutually counterweight one another. As my present invention is applicable to windows thus cons'tructed, itwill joe obvious in such event that a special cfi'ofrrpaitment in the, jamb to receive, sash counterweights will not be necessary.

I claim:

1. A Windowframe and sash construction comprising jambs having their inner walls formedin three vertical sections with gaps between the sections, sashes extending into such'gaps, and means within .the jambs op e' rated bythe closing movement of the lower sash adapted automatically to cause both the upperand lower sash to be pressed against the middle vertical jamb sections when the window is closed.

2. construct-ion 1s defined in claim 1 in which the means for pressing the sashes against the middle vertical jamb sections comprises a movable clamping member adapted to be operated by the lower sash.

3. A window frame comprising jambs,

two sashes sliding in said jambs, a pair of auxiliary members, one forming a part of each jamb, and means for causing such members, as the window is finally closed, to move to hold a. face ofeach sash against a guide portion of the j'amb for substantially the height of each such sash.

4. A'ifwindow frame comprising jambs, two s'ashessliding in said, jambs, a pair of auxiliary members, one forming a part of each jamb, and ineans controlled by the final closing and initial opening movement of the lower sash adapted automatically to .cause such members to move as the window is finally closed,to hold aface of each sash against a guide portion of the jamb for substantiallyth'e height of each sash, and

adapted automatically to permit such membars to move as the lower sash is initially opened to allow the lower sash to slide with space betwl (in it and such,fiXed amb portion. v

5. A window frame and sashes, comprising jambs having their innerv walls formedin three vertical sections with gaps between the sections for receiving the sashes, sashes slidable in such gaps, and having the middle vertical sections movable in relation to the portion of the jambs which support them, and auxiliary sealing means forming part of each janib adapted to cause a face of one sash to press against such. middle sections for substantially the entire height of such sash so that such-middle sections are moved in relation to the portion of the jamb which supports them and are pressed against a Face of the other sash for substantially the entire height of suchother sash.

6. A window frame and sashes, comprising jambshaving their inner walls formed in three vertical sections with gaps between the sections for receiving the sashes, sashes slidable in such gaps, a cam member in each jamb, means for permitting relative move- 10 ment between the middle jamb sections and such cam members, and complementary cam members carried by the lower sash and adapted, as the lower sash is closed, to cooperate with such first mentioned cam memhere to press the lower sash against such middle sections and to cause such middle sections to be pressed against the upper sash.

' In testimony whereof I have afiixed by I signature.
