WINDOW Filed April 29, 1948 2 Sheets-Sheet 2 Patented Nov. 28, 195i) UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to improvements in windows for buildings and the like.

The primary object of my invention is to provide a simply constructed, inexpensive window of the sliding sash type and in which sash balances, such as sash cords and weights or spring balances, are eliminated, the sashes are mounted for easy raising and lowering into different set positions, adequate insulation is attained, and the sashes are easily removed and replaced with less eiort and in less time than with conventional sliding sash windows.

Another object is to provide a window con structed and arranged for the attainment of the above objects and embodying improved locking means for the sashes.

Other and subordinate objects, within the purview of my invention, together-with the precise nature of my improvements, will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in vertical section of a window constructed in accordance with my invention, in a preferred embodiment thereof and viewed from the outside;

Figure 2 is a view in vertical section taken on the line, 2-2 of Figure l;

Figure 3 is a view in horizontal section taken on the line 3-3 of Figure 1;

Figure 4 is a fragmentary view in vertical section taken on the same line as Figure 2 and drawn to a larger scale to better illustrate the sash lock;

Figure 5 is a view in vertical section taken on the line 5--5 of Figure 1;

Figure 6 is a similar view taken on the line 6 6 of Figure 1;

Figure 7 is a view in perspective of one of the L sash guides;

Figure 8 is a similar view of one of the side stiles;

Figure 9 is a view in horizontal section taken on the line 9-9 of Figure 1;

Figure 10 is a view in perspective of one of the sash guide tensioning devices;

Figure 11 is a similar view of one of the sash guide mountings;

Figure 12 is a view in perspective of one of the angle brackets.

Referring to the drawings by numerals, my improved window, as illustrated, comprises a frame designated generally by the numeral I and which includes a pair of side stiles 2, a header 3, and a sill member 4.

The side stiles 2 are set in from the ends of the header 3 and sill member 4 and have the upper and lower ends thereof mortised into the header 3 and sill member 4, as at 5, 6. Also the side stiles 2 are rabbeted and L-shaped in cross section and have suitably secured to outside edges thereof upright outside strips I forming with said stiles 2 vertical channels 8 in confronting faces of said stiles extending from the sill member 4 to the header 5. An outside cross keeper strip 9 extending along the header 3 is suitably secured thereto to depend below the same for a purpose presently clear.

The usual outside trim I0 is suitably fixed t0 the strips l, 9 and the usual inside trim II to the inside edges of the side stiles 2 and to the header 3 and sill member 4 which carries the usual stool cap strip II'.

A pair of vertical strip-like sash guides I2 are mounted, as presently described, in the channels 8 to extend from the sill member 4 to the header 3 with a slight clearance at the ends thereof and are tensioned, by means also presently described, to grip therebetween a pair of upper and lower sashes I3, I4 slidable along said guides to raise and lower the same, said guides acting to frictionaily hold said sashes, yieldingly, in diierent raised and lowered positions.

The strips 9 overlap the outer sides of the upper sash I3 and form a seal at the sides of said sash, and also at the top of said sash when the same is closed. Vertical. half round tongue and groove guiding and insulating connections I5, I5' are provided between the sash guides i2 and the upper and lower sashes I3, I4, the tongues I5 being on the sash guides I2 and the grooves I5 in said sashes.

Insulation strips I5, II are set into the top edge of the upper sash I3 and into the bottom edge of the lewer sash t5 to seatin longitudinal grooves I8, I9 in the header 3 and sill member 4 respectively.

The mounting for the sash guides I2 comprises studs 2) adjacent the upper and lower ends of said guides having base iianges 2l secured by screws 22 to sa'd guides I2, said studs extending horizontally from said guides through apertures 23 in the side stiles 2 and through guide plates 24 secured to said side stiles 2 by screws-35. Midway of the ends thereofl the sash guides I2 are also mounted on the side stiles 2 by means of pairs of guide studs 26 spaced apart laterally of the side stiles 2 with base flanges 21 secured to said stiles by screws 28, said studs extending through apertures 29 in said stiles and through guide plates 3B secured to said stiles by screws 3 I.

A pair of upper and lower coil springs 32, 33 tension the sash guides I 2 at the upper and lower ends of said guides. The upper coil spring 33 extends along the header 3 in an upper rabbet 34 therein and is attached at its ends to hook screws 35 extending upwardly from the upper )nds of said guides I2 through slots 36 in the header 3. The lower coil spring 33 extends along a bottom channel 31 in the sill member 4 and is attached at the ends thereof to right angle brackets 38 extending outwardly from the lower ends of the sash guides I2 through slots 39 in the side stiles I2, and then downwardly into the sill member 4 into the channel 33 by way of slots 46 in said sill member 4.

Suitable dust guards cover the slots 39 and 40. Coil springs 42 on the guide studs 26, interposed between the base anges 21 of said studs and the guide plates as supplemental tensionsprings for the sash guides I2 and in the transverse centers of said sash guides to prevent said guides from bending outwardly in the center portions thereof.

A sash lock is provided between the upper and lower sashes I3, I4 comprising a keeper plate 43 set into the lower bar 44 of the upper sash I3 in a recess 45 in said bar. A latch bolt 46 is slidable in the upper bar 41 of the lower sash I4 toward and from saidkeeper plate 43, and is urged by a coil spring 46 thereon toward said plate 43, the coil spring being housed in a recess 49 in said bar 41 and through which the latch bolt 4G extends.; A lateral handle 53 with a hand grip knob 5I thereon is provided on one end of the latch bolt 46 for pulling the same away from the keeper plate l43, said handle 56 working in a notch 52 in said bar 41. The other end of the latch bolt 46 has pivoted thereto, as at 53, a latch plate 54 pivoted, as at 55, on attaching plate 56 secured to the upper bar 41, in any suitable manner, and adapted to be swung by the latch bolt 4 6, under the urge of the coil spring 48, beneath a hooked edge 51 on the keeper plate 43, whereby said sashes I3, I4 are locked against relative vertica movement from closed position. By pulling on the handle 50, the latch plate 56 may be swung out from under the hooked edge 51 and out of the recess 45 to unlatch said sashes.

As will now be seen, the sash guides I2 grip or clamp the sashes I3, I4 therebetween with suilcient pressure to maintain the same in different raised and lowered positions, but with a tongues I4 out of the grooves I5 so that said sashes can be freed for removal from between said sash guides I2.

The foregoing will, it is believed, suice to impart a clear understanding of my invention, without further explanation.

Manifestly the invention, as described, is SuS- ceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

Having described my invention, what is claimed as new 1s:

1. In a window, a frame including side stiles with inner side channels, a header and a sill member having a` bottom longitudinal groove therein, a pair of upper and lower sashes in said frame offset relatively for vertical movement past each other, a pair of upright sash guides between said stiles in the channels thereof and between which both said sashes are interposed and guided therein for vertical sliding movement, means for causing said guides to frictionally grip said sashes yieldingly with suiicient pressure to hold the same stationary when moved vertically into different positions comprising hooks on the upper ends of said guides, a spring extending along the top of said header and connecting said hooks, brackets depending from the lower ends of said guides, and a spring in said groove connecting said brackets.

2. In a window, a frame including side stiles with inner side channels, a header and a, sill member having a bottom lQngitudinal groove therein. a pair of upper and lower sashes in said frame offset relatively for vertical movement past each other, a pair of upright Sash guides between said stiles in the channels thereof and between which both said sashes are interposed and guided therein for vertical sliding movement, and means for causing said guides to frictionally grip said sashes yieldingly with suiliclent. pressure to hold the same stationary when moved vertically into different positions comprising hooks on the upper ends of said guides, a spring extending along the top of said header and connecting said hooks,
