Fig. 1 is an exploded, fragmentary, perspective view of a window embodying the features of the present invention;

Fig. 2 is a transverse sectional view taken along line 2-2 of Fig. 1;

Fig. 3 s a vertical sectional view taken along line 33 of Fig. l and Fig. 4 is a fragmentary perspective view of the inner side of the window showing the push-pull locks.

Referring now in detail to the figures and in the practice of my invention, there is shown a window consisting of a lower window sash, referred to collectively as 5, and an upper window sash, referred to collectively as 6.

The lower window sash 5 consists of the usual horizontal portions 7 and 8 and the vertical portions 9 and 10 surrounding the usual visual opening 11, the vertical portions 9 and the horizontal portion 8 being provided on the outer sides thereof with a longitudinal, outwardly extending ridge 12 of semi-circular cross section. The vertical portion 10 is provided on the outer side thereof with a longitudinal, outwardly extending ridge 13 having teeth 14 at an angle thereto.

The upper window sash 6 consists of the usual horizontal portions 15 and 16 (not shown) and the vertical portions 17 and 18 surrounding the usual visual open- 2,703,726 Patented Mar. 8, 1955 ing 19, the vertical portion 17 and the horizontal portion 16 being similarly provided on the outer sides thereof with a longitudinal, outwardly extending ridge 12 of semi-circular cross section. The vertical portion 18 is provided on the outer side thereof with a longitudinal, outwardly extending ridge 13 having teeth 14 at an angle thereto.

The upper and lower window sashes 5 and 6 are each provided with the usual recesses 20 surrounding the visual openings 11, 19 adapted to receive the window panes 21 secured thereto by putty 22.

Referring now particularly to Fig. 2, the window casement consists of a pair of vertically extending channel members 23 secured to the wall 24 by screws 25 and a second pair of channel members 26 vertically extending and secured to the wall 24 on the other side of the window in a manner to be described below.

The channel members 23 are each provided with longitudinally extending recesses 27 on the sides adjacent the window, of semi-circular cross section and adapted to snugly receive the ridges 12 of the vertical portions 9 and 17. The channel members 23 are spaced from each other by a vertically extending spacing element 28 positioned between adjacent sides of the channel members as clearly shown in Fig. 2. A vertically extending wood panel 29 is secured in conventional manner to the wall 24 on the inner side thereof adjacent the inner channel member 23 and overlaps the inner side thereof. A beveled wood panel 30 coincides with the outer edge of the panel 29 and with the inner side of the inner chanand is provided with an opening 31 in alignment with corresponding openings in the inner and outer sides of the channel member 23 and in the spacing element 28 and receives a bolt 32 threaded at the end to engage the internally threaded openings in the outer side of the inner channel member 23 and the spacing element 28 whereby to secure the spacing element to the channel member 23 and to further secure the inner channel member 23 itself to the beveled panel 30, which is in turn secured to the wood panel 29 in conventional manner. It is obvious that a plurality of bolts 32 may be positioned along the vertical length of the beveled panel 30. The outer channel member 23 is fixedly secured to a plurality of L-shaped brackets 33 by means of rivets 34 which are in turn fixedly secured to the wall 24 in conventional manner.

The vertically extending channel members 26 are positioned on the other side of the window intermediate the window and the wall 24 and are separated by a spacing element 28 from each other, in a manner similar to the channel members 23. The outer channel member 26 is fixedly secured to a plurality of L-shaped brackets 33 by means of rivets 34 which are in turn fixedly secured to the wall 24 in conventional manner, and is provided on the side adjacent the window with vertically extending recess 35 of rectangular cross section and adapted to receive the outwardly extending ridge 13 and the teeth 14 of the vertical portion 18 of the upper half 6.

A vertically extending wood panel 29 is similarly secured in conventional manner to the wall 24 on the inner side thereof adjacent the inner channel member 26 and overlaping the inner side thereof. A second wood panel 30 coincides with the edge of the panel 29 and with the inner side of the inner channel member 26 and is provided with an opening 31 in alignment with corresponding openings in the inner and outer sides of the channel member 26 and in the spacing element 28 and similarly receives a bolt 32 threaded at the end to engage the internally threaded openings in the outer side of the inner channel member 26 and the spacing element 28 whereby to secure the spacing element to the inner channel member 26 and to further secure the inner channel member itself to the beveled panel 30, which is in turn secured to the wood panel 29 in conventional manner. A plurality of bolts 32 are secured along the vertical length of the beveled panel 30 whereby to securely fasten the inner channel member 26 and the spacing element 28 in position. The inner channel member 26 is a vertically extending recess 35 of tion and adapted to receive the outwardly extending ridge 13 and the teeth 14 of the vertical portion 10 of the lower window sash 5.

The inner channel member 26 is provided with a recess 36 and a vertically extending slot 37 adapted to cooperatively receive a push-pull lock 38 consisting of a handle 39 adapted to reside in the recess 36 and a head 41) adapted to reside in the slot 37. The head 40 is provided with angular teeth 41 adapted to engage the teeth 14 when the handle is pulled outwardly and to disengage the teeth .14 of the vertical portion 10 when the handle is pushed in. To facilitate pushing and pulling of the handle 39 a flange 42 is integrally formed at the outer end thereof.

Referring now to Fig. 3 and in further practice of my invention, the horizontal portion 15 of the upper window sash 6 is provided with a plurality of cylindrical holes 43 adapted to receive a plurality of shafts 44 having hemispherical heads 45 rigidly secured to the outer ends thereof. A helical spring 46 surrounds the shaft 44 in each case and is secured to the head 45 at one end and to the horizontal portion 15 at the other end and serves to maintain the head 45 normally outward of the horizontal portion 15. The horizontal portion 7 of the lower window sash is provided on the side adjacent the horizontal portion 15 with a corresponding plurality of cylindrical holes 43 in alignment with the first mentioned holes adapted to receive a plurality of shafts 47 having concave heads 48 rigidly secured to the outer ends thereof and adapted to receive in snug engagement the heads 45. A helical spring 49 surrounds the shaft 47 in each case and is secured at one end to the horizontal portion 7 and to the head 48 at the other end and serves to maintain the head 48 normally outward of the horizontal portion 7 and in snug engagement with the head 45 as clearly shown in Fig. 3.

The outer channel member 26 is similarly provided with a recess and a vertically extending slot adapted to cooperatively receive a second push-pull lock positioned above the lock 38, as shown in Fig. 1 whereby to similarly lock the upper window half 6 in any desired position.

Referring now to Fig. 1, and in further practice of my invention, there is shown a burglar alarm 50 and a switch 51 connected to a household source of power not when, in the basement of the house and having one terminal connected to the inner channel member 26 and the other terminal releasably connected to a thin flange 52 formed in the lower portion of the head 40. push-pull lock 38 is pulled out and therefore in the locking position, the flange 52 is out of engagement with the aforesaid terminal. When the push-pull lock 38 is pushed in and therefore in the unlocking position, the flange 52 slides into engagement with the aforesaid terminal, completes the circuit and sounds the burglar alarm. When it is desired to operate the push-pull locks for normal purposes, the switch 51 is of course open. obvious that the wires of the burglar alarm 50 may be secreted on the unlocking portion of the channel member 26. The same system can be used with holes and prongs to the locking part of the handle 39.

in operation, the upper and lower window halves are slidably housed within the outer and inner channel members described above, with the ridges 12 and 13 riding in the recesses 27 and 35 respectively. Frictional engagement occurs between the ridges 12 and the recesses 27, and on both sides of parting strips 28 and 28 due to the spring pressure from 47 and 45-as shown in Fig. 3- the ends of which taper off to slide on guides 28 and 28, thereby reducing surface resistance to lowering and raising the window halves. The recesses 27 also act as a guide for the ridges 12 creating sufficient resistance against overfreedom of the windows. Effective weather stripping is provided in the combination of the brackets 33, the outer channel members 23 and 26, the spacing elements 28, the inner channel members 23 and 26 and the beveled wood panels 30, the juxtaposition of metal to metal creating greater stability than in conventional window easements.

It should be Further stability and elimination of weather is provided by recesses 54 located in the window sill 53 and adapted to receive in snug engagement the ridge 12 of the horizontal portion 8, a similar recess being provided in wall 24 above the horizontal portion 16 of the upper half 6,

Further stability and the elimination of rattling is effected by the plurality of heads 45 in spring engagement with the heads 48 when the window is closed, this spring engagement also serving to keep the ridges 12 tight within the recesses 27 and giving perfect performance of the window under all conditions of weather.

The teeth 14 of the ridges 13 on the vertical portions 10 and 18 serve the twofold purpose of providing weather stripping and also as a means to lock the window halves at any point when combined with the pushpull lock 38. When the wndows are securely locked in the above described manner the elimination of petty thievery is assured. Throwing of the switch 51 assures burglar-proofing by sounding the alarm 50 when the pushpull locks are jimmied.

When the two window halves are closed, tightness is maintained by the plurality of heads 45 in spring engagement with the heads 48 and by the snug engagement of the ridges 12 within the recesses 27, the end heads 45 in spring engagement with the end heads 48 applying pressure to the ends of the ridges 12 in the recesses 27 creating a tensional point of resistance, thus stopping over freedom of the windows prior to moving.

It should now be apparent that there has been provided an improved window and casement therefor which will provide tightness when closed, which eliminates rattling,

which eliminates frictional sliding and which includes novel means for weather stripping thereby eliminating costs of labor and material in installing and removing weather stripping in conventional windows and easements now in use. It should also be apparent that there has been provided an improved window and casement therefor which includes novel spring tensioning means for tightening the window, novel means for locking the window at any point and means for burglar-proofing the window by an electrical alarm.

While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

A meeting rail latch and anti-rattle structure comprising a lower rail of an upper sash in combination with an upper rail of a lower sash, said rails having a plurality of substantially cylindrical holes, a plurality of substantially cylindrical shafts placed in said holes so that they may move inwardly and outwardly thereof, hemispherical heads rigidly secured to the ends of said shafts external of said holes of one of the said rails, helical springs surrounding each of said shafts intermediate the said heads and the said sashes whereby to normally urge the heads outward of the said holes, concave heads rigidly secured to the said shafts at the ends external of the said hole of the other of the said rails, helical springs surrounding each of the said last mentioned shafts intermediate said concave heads and the said sashes whereby to normally urge said concave heads outwardly of said holes and into tensional engagement with said hemispherical heads whereby to prevent rattling of the window sashes when closed.
