5 Claims; (Cl. Mia-49') Tli'e'present-invention relates to windows-and refers more particularlyto windows com-prising sash which are both slidablein a- -vertical-direc-- tion and' tiltable ona substantially horizontab axis.

Referring now indetailtothe-drawings my improved 'window 9 is-shown in perspective in Figuralin'whichthe general appearance of" the window-complete with inside trim is shown:

Two stile members, II are mounted on the pulley, stiles ,offthe conventional window frame I0. III F gu resv2', 3; 4 and'5..is,illustrated theleit stilevof; the window. framelook-ing at ltheiwindowl. from the room. Stile I I is of sheetgmetal such as.

I16"; I11;

decreased by turninga screwlocated the 5-5 sidewall portions I-6",- II"are relievedattheir rear-boundariesbytheslots I 8, I9; which are about 'si-x inches long' and extend for equal dis}- tances above and" below the countersunk" hole which is substantially at the height of the meeting rail of the sashes 2 I, 22.

Referring to Figure 2, in which sash 2!, 22 have been omitted, a runner 23 is slidably mounted in channel l2 and a similar runner 24 is slidably mounted in channel l3. Runners 23, 24 have integral flanges 25, 26 which are bent so as to form a U shape with the body of the runher, as best shown in Figure 4.

Runner 23 'is further formed with the pivot hole 21 and the arcuate slot 28.

The tilters 29, 30 are metal members of L cross section, a pair of tilters on opposite sides of the window constituting mounting means for a sash 2| or 22, which are preferably permanently mounted in the pair of tilters by screws or other conventional means.

Tilter 29 is formed with the pivot hole 3i and the square hole 32 at a-substantial distance there from.

The bolt 33 has a square shank portion 34 which fits vnonrotatably in hole 32 and rides in the slot 26 when tilter 29 is tilted on pivot 35.

Inside of runner 23 and on the opposite side thereof from tilter 29 is firmly mounted, as by welding, the friction plate 36 formed with the arcuate slot 31 coincident with slot 28.

Washers 38, 39, 40 are mounted on bolt 33 between tilter and runner, runner and friction plate, and friction plate and nut 4| respectively,

washers 38, 39, 46 being formed with holes complementary to the square shank portion 34 so as to be nonrotatable thereon. It is evident from the above that bolt 33 also extends through slot 31 of friction plate 36 and that nut 4| threadedly engages bolt 33.

The above described mechanism constitutes a tilt lock which by adjustment of nut 4| on bolt 33 by insertion of a wrench into the lower end of runner 23 as indicated by arrow 42 permits the development of any desired degree of sliding friction between tilter 29 and runner 23 so thatv the tilter can maintain any angular position to which it is set relative to runner 23. 7

Screw 43 passes through countersunk hole 26 in face portion I5 of parting strip [4. Compression coil spring 44 is mounted concentrically on screw 43 between face portion I5 and tapered, elongated nut 45 which is threadedly engaged by screw 43.

Nut 45 engages the side wall portions l6, I! to distend the same laterally when screw 43 is taken up, thus creating frictional engagement between portions I6, I! and the runners 23, 24 of both upper and lower sash, thus providing easy adjustment of the sliding friction between runners and stile ll so that the runners maintain any vertical position to which they may be set.

The flanges 25, 26 overlie the upper extremities of the tilters when the latter are in closed position, as illustrated re tilter 36, Figures 2 and 4,

while an open position of tilter 29 is also illustrated in Figure 2. 7

Means for floatingly mounting the. stiles H in the window frame 10 are provided in the tongues 46 struck out of the material of II, one tongue 46 being located about one foot from the end of each channel l2, l3. Tongues. 46 are integral with stile l I, being connected thereto, at

their upper end, and free standing along their side and bottom boundaries. A nail or screw driventhrough each tongue 46 into the .conventional pulley stile serves to mount the stiles II in the frame I0 and guards against poor sliding of the sash due to compressive deforming of frame In by settling of the wall which may cause 7 the opening to get out of square. Slight settling of the window opening is enough to deform a frame I0 conventionally mounted therein, but the present invention permits stile II to maintain its correct relation to the sash, thus permitting normal functioning of the window.

It will thus be seen that there is provided a device in which theseVeraI objects of this invention are achieved, and which 'is well adapted to meet the conditions of practical use. As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be 7 understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

What is claimed is:

1. In a window construction of the type comprising slidable and tiltable sash, a runner member slidable in the window stile, a tilter member constituting mountingmeans for said sash and a pivot connecting said tilter to said runner, the

improvement comprising said runner member being formed with a slot, said slot describing a segment of a circle around the center of said pivot, and said tilter member being formed with a hole, a bolt passing through said slot and hole and a nut engaging said bolt and thereby drawing said tilter and runner into frictional engagement to constitute a tilt lock. 7

2; Tilt lock means for tiltable and slidable sash comprising the combination with a tilter member firmly connected to said sash, a runner member slidably engaging thewindow frame, and a pivot connecting said members, of a third member firmly mounted on said runner member on the opposite side thereof from said tilter member, said tilter member being formed with a hole, said runner and third members being formed with slots, said slots describing a seg-. ment of a circle around the center of said pivot, a bolt passing through said hole and said slots, and a nut on said bolt in back of said third member.

3. Tilt lock means, for a tiltable and slidable sash comprising the combination with a tilter member firmly connected to saidsash, a runner member, slidably engaging the window frame and a pivot connecting said members, of a third member firmly mounted on said runner member on the opposite side thereof from said tilter member, said tilter member being formed with a hole, said runner andthird membersbeing formed with slots, said slots describing a segment of a circle around the center of said pivot, a bolt passing through said hole and said slots, a nut on said bolt in back of said third member, and washers on said bolt between said tilter and said runner member and between said runner and third member and between said third member and said nut.

4. In a tilt lock means according to claim 3, said bolt comprising a portion of noncircular cross section and said washers being shaped complementary to said portion.

5. Tilt lock means for a window with slidable and tiltable sash, said means comprising, in combination, a tilter member firmly connected to sa1d sash, a runner member of U-cross section,

the bight' of the U abuttingsaid tilter member and the arms of the U slidably engaging the winon the bight of said runner member adjacent the lower end thereof and on the opposite side thereof from said tilter member, said tilter member being formed adjacent its lower end with a hole for a pivot, said runner and said third members being formed with slots, said slots describing a segment of a circle around the center of said pivot, a bolt passing through said hole and said slots, a nut on said bolt in back of said third member, and washers on said bolt between said tilter and said runner members, and between said runner and said third members and between said third member and said nut, said nut being accessible for adjustment via the open lower end of said runner member.
