This invention relates to a novel multiple sliding sash window structure having novel combination sash locks and lifts.

The primary object of the invention is the provision of window structure of the kind indicated which is more convenient, practical, and efficient, and wherein novel combined sash lock and lift mechanisms are incorporated in each sash and enable the sashes to be pushed up to various opened positions without manual operation of the mechanisms, and which enable easy and quick removal of sashes from the frame.

Another object of the invention is the provision of ratcheting mechanisms of the character indicated above which are adapted to be incorporated in the bottom cross members of sashes, at one, and preferably both ends thereof, the mechanisms having spring-projected locking shafts, provided with radial handles for imparting longitudinal and rotary movements to the shafts, and pin and slot means which serves to produce rotation and retraction of the locking shafts, out of locking engagement with detent means on the side members of the frame of the structure, to enable downward shifting of sashes, the slot means further providing for further manual retraction of the bolts to clear the frame side members and enable the sashes to be withdrawn inwardly out of the frame and shifted sidewise for removal of retaining pins or legs, on the upper parts of the sides of the sashes, from the frame.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes =of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is an inside elevation, partly broken away and in section, of a window structure equipped with combination sash locks and lifts of the present invention;

FIGURE 2 is an enlarged and vertically contracted vertical transverse section taken on the line 22 of FIG- URE 1;

FIGURE 3 is a further enlarged fragmentary horizontal section taken on the line 33 of FIGURE 1;

FIGURE 4 is a fragmentary vertical longitudinal section taken on the line 4-4 of FIGURE 3;

FIGURE 5 is a view similar to FIGURE 4, but showing the lock component rotated and withdrawn from the detent component;

FIGURE 6 is a fragmentary vertical transverse section taken on the line 6-6 of FIGURE 4; and,

FIGURE 7 is a fragmentary vertical transverse sec tion, similar to FIGURE 2, but showing the middle sash in fully closed position, with the lift handle of its lock and lift means disposed at a lateral angle and engaged with a part of the lower cross member of the frame, in full lines, and in lifted position in phantom lines.

Referring in detail to the drawings, wherein like numer-als designate like parts throughout the several views, the illustrated window structure comprises an open rectangular, vertically elongated frame 10, having vertical side members 12, a top cross member 14, and a bottom cross member 16. The frame 10 being set into a window frame F. The side members 12 each have formed therein inwardly facing inner, middle, and

outer channels

18, 20, and 22, respectively, which have

webs

24, 26, and 28, respectively. Vertical laterally spaced flanges 30 and 32, and 3d and 36 define the channels therebetween. The bottom cross member 16 is of the stepped type and is formed with outer, middle and inner channels 38, 4t), and 42, respectively, the webs of these channels being on successively lower levels, as shown in FIGURES 2 and 7. The

inner flanges

44 and 46 of the outer and middle channels have stop ribs 4 8 and 50 which extend laterally outwardly therefrom, at the difierent levels, and the inner flange 52 of the inner channel has thereon a laterally received extending rib 5'4 thereon.

The web 26 of the middle channel 20, taken by way of example, since the web of all of the channels are adapted to be so provided, is provided, at vertically spaced intervals, with rectangular detent openings 58. The

openings 58 are produced by cutting the material of the web and bending therefrom laterally outwardly and downwardly angled tongues 66, and detent edges 62 beneath the tongues, as shown in FIGURE 5.

Slidably and removably engaged in related ones of the

channels

18, 20, and 22, are inner, middle, and

outer sashes

64, 66, and 68, respectively. The outer and

middle sashes

66 and 68 are similar and have glass panes 69 therein, while the inner sash 64 has a screen panel 70. The three sashes involve rectangular frames 72 having vertical side members 24, top cross members 76 and bottom cross members 78 in the form of rectangular tubular housings. The bottom cross member of the inner sash 64 has added thereto a screen attaching member 80, shown in FIGURE 2. The sashes are of a width to be removed, inwardly, through the opening of the frame 10, and are held in their channels by lateral pins 82 at the upper ends of their side members 74, and by components of the combination lock and lift mechanisms, which are housed in the housing 78 on their bottom cross members. The pins 82 are short enough to enable one side of the sash to be raised vertically, after the sash has been detached at the bottom, from frame 10, and the sash lowered to a plane perpendicular to the frame.

The illustrated combination lock and lift mechanisms '84 of the sashes are similar, and are provided at each side of the sashes, in reversed positions. Each mechanism comprises a horizontal cylindrical tube 86, of a length less than half the width of a sash, and extending through the related outer end portion of a rectangular housing 78, and held in place thereon by suitable means, such as a screw 88, which, as shown in FIGURE 3, is threaded through a sidewall of the housing, the sidewall of the tube 86, and into a stop block 92 which is positioned in the inner end of the tube 86.

Slidably and rotatably engaged in the tube 86 is a round shaft 94, having an inner end d6 spaced from the stop block 92, by a helical spring 98 which is compressed between the end 96 and the block 92 and urges the shaft outwardly. The tube 86 has an outer end 100 which is inwardly spaced from the outer end 101 of the housing 78, and is located close to the inner end of a longitudinal slot 102, formed in the bottom wall 104, of the housing and spaced from the outer end 101 of the housing. The outer end of the housing is provided with an internal annular stop 106 with which an annular stop collar 1% on the shaft 94 engages in the normal, extended or projected position of the shaft. The shaft 94 terminates, at its outer end, in an extension 110 having a bevelled end 112 which faces upwardly, as shown in FIGURE 4, so as to have cam engagement with a tongue 6% of the channel web 56, while the unbevelled lower side of the extension rests upon .the detent edge 62 of the web opening 58, so that the sash is held up in a selected position in the frame 10.

Aflixed to the shaft 94 and normally extending downwardly through the housing slot 102, in a perpendicular position, is a flat radial handle 114, which is narrower than the slot 102, and which, in the normal projected position of the shaft 94, is at the outer end of the slot 102. At a location between the ends of the tube 86 the shaft 94 is provided, on its inner side, with a radial pin 116 which is slidably confined within a compound slot 118.

The compound slot 118, as shown in FIGURES 4 and 5, is composed of a relatively long horizontal upper longitudinal slot 120, a relatively short lower slot 122, which is spaced parallel to and displaced outwardly relative to the upper slot 120, and a diagonal slot 124 which extends between and opens to the outer ends of the

slots

120 and 122. In the normal outwardly projected position of the shaft 94, shown in FIGURE 4, the pin 116 is positioned at the outer end of the lower slot 122 and is held there by the force of the spring 9-8, so that the sash is locked. If it be desired to raise the sash in the frame 10, it is not necessary to manipulate the handle 114, and the sash can be moved upwardly, simply by pushing upwardly thereon, since the bevelled end 112 of the shaft extension 110 will case against the tongue 60, a

and succeeding tongues and the shaft will thereby be retracted, against the resistance of the spring 98, with the extension sliding on the web 56 between detent opening 58. When a new elevated position of the sash is reached, the unbevelled' part of the shaft extension 110' bears downwardly upon the detent edge 62 of a related opening 58 and holds the sash in the new position.

When it is desired to remove the sash from the frame 10, it is necessary only to reach behind the handle 114 and pull the same inwardly and upwardly away from the sash, while pushing the handle inwardly away from the related side member of the frame. This notches the shaft 94 outwardly, so that the pin 116 moves out of the lower slot 122 and upwardly along the diagonal slot 124, into the upper slot 120, and inwardly along the upper slot 120, is indicated in FIGURE 5, whereby the shaft extension lltl is retracted into the'housing 7%, far enough to clear the same out of a related window frame side member channel and enable removal of the sash from the frame, with the shaft extension at the other side of the sash retracted in the same way.

When the inner or screen sash 64 is in an elevated position, and .the'mi-ddle sash 66 in a depressed freely closed position, the handles 114 of the middle sash are adapted to be engaged with the flange 54 of the inner channel flange 52, as shown in FIGURE 7, with the handies in a downwardly and inwardly angled position, in which the handles are more accessible for easy actuation. The handles 114 have, on their undersides, hooks 115, which retainably engage under the flange 52.

Although there havebeen shown and describedherein preferred forms of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.
