. 3 Claims. 1

This invention relates to windows for houses, buildings and the like and, more particularly, is concerned with a window sash holder which will support a window sash in any vertical position without the use of counterweights.

It has been proposed heretofore to provide windows with resiliently positioned sash supporting channels which eliminate counterweights, but known structures are open to the objection that the spring tension on the sash guiding channels is often not in the proper amount, so that the window will either be so tightly held that it cannot be moved, or so loosely held that it will not stay in raised position. Again, known structures of the indicated type are relatively costly and difficult to install and offer problems and complications with respect to locking of the sash against removal from the guide channels.

It is the general object of my invention to avoid and overcome the foregoing and other difculties of and objections to known windows of the indicated type by providing an improved, weather proof, readily installed, inexpensive, and efficient window sash-holder assembly which will provide for non-sticking vertical movement of the sash without the use of counterweights and yet will firmly hold the sash at any desired raised position.

Another object of my invention is the provision of a simple window sash-holder which will permit easy removal of the window sash from the frame from either the inside or outside of a building, for example, to facilitate cleaning of the window panes.

Another object of my invention is to provide an inexpensive positive locking unit to prevent removal of the sash from the window.

The aforesaid objects of my invention, and other objects which will become apparent as the description proceeds, are achieved by providing a complete window assembly including a main frame, a pair of fixed guide members secured to one side jamb of the frame, and a pair of yieldable guide members on the opposing side jamb of the frame. A pair of conventional window sash members are disposed between said yieldable and fixed guide members and are thereby frictionally supported in the frame in any desired vertical position. Tongues on the side of each sash slide in corresponding grooves formed in said guide members. Resilient adjustable pressure means, to be described in detail hereinafter, are provided to permit the frictional pressure between the guide members and the sash tobe varied. The sash is adapted to'be removed by forcing the sash against the yieldable guide member. This will cause the entire sash to move laterally so that the tongue on the opposite side of the sash from the yieldable guide may be removed from the groove in the stationary guide member. The whole sash can then be swung in or out and withdrawn from the window frame. A loci; mechanism is provided to prevent depression of the yieldable guide member and removal of the sash.

For a better understanding of my invention, reference should be had to the accompanying drawings, wherein Fig. 1 is a front elevational view of one form of the window frame and improved sash holder of my invention;

Fig. '7, still relating to the lock, is an enlarged fragmentary sectional view taken on the line VII-VII in Fig. 6.

With specic reference to the form of the invention illustrated in the drawings, the numeral Il] indicates generaly a complete window frame and sash assembly. The window frame is of the conventional type including a head or transverse top board l2, vertical boards or side jambs I4, and a bottom sill I6. At one side of the frame I0, a pair of stationary channel-shaped guide members i8 are secured in side-by-side relation to the side jambs as by screws 20. Grooves 22 are provided running the length of the transverse face of the channels 2U. These grooves serve as guides for the vertical movement of one vertical edge of the upper and lower window sash, indicated generally at 24. The window sash is of the conventional type including a frame 26 having tongues 28 along its vertical sides. These tongues engage the grooves 22 to hold the sash in position and yet permit vertical movement of the sash in the Window frame.

Yieldable guide members are provided on the opposite sides of each sash from guide members I8 and are indicated generally at 33. Each guide member 30 is assembled as a unit before being secured in place in the window frame. Each yieldable guide member assembly includes a stationary channel member 32 which rests against the side jamb I4 of the window when the assembly is in position. Formed on the outer edges of this channel are lips 34 which engage inwardly turned lips 3B formed on channel member 33. Thus, when channel member 32 is slid within the channel member 3S, the two are interlocked as shown in Fig. 2. Each channel member 33 is provided with a longitudinal groove d5 which serves as a guide for the tongue 28 on the vertical edge of the sash frame 25.

The vchannel member 38 is resiliently urged away from the channel member 32 and into frictional engagement with the edge of the sash 23 by means of a plurality of compression springs 42 which are provided at spaced points between the channel members, for example near the top and bottom ends thereof. When the sash 2B is removed, as for cleaning, flanges 35 and 35 are urged by the springs into engagement, the flanges acting as stops t restrict the relative movement of the channels apart.

An important feature of my invention is to vary the frictional, resilient pressure exerted by channel 38 against the edge of sash 23. Details of this arrangement can best be understood by reference to Figures 2, 3, and 4 of the drawings. Associated with each spring 'i2 is a fiat-head screw i4 which extends through a countersunk hole in the bottom of the groove it of channel 38. This screw passes through the center of the compression spring 42 and into threaded engagement with an H-shaped nut shown at 43. This nut 48 is guided for sliding but non-rotative movement on a yoke or U-shaped bracket 55 which is spot-welded or otherwise secured to a similar but shorter bracket 52. A hole t is provided in the end lof the bracket 52 to permit the screw t4 topass freely through it.

A smaller compression spring 53 surrounds screw M between the nut 43 and the bottom of bracket 52. This spring 58 performs two special functions. First, the spring 58 urges nut 43 in a direction to keep the nat head of the screw M flush with the bottom of the groove L33 at all times. Thus, regardless of the resiliently floating movement of the channel member 38 against compression spring 42 as the sash is raised and lowered, compression spring 53 will at all times insure that the head of screw A will not project out into groove -fi so as to intersect or stop the movement of sash 26. Second, the reaction of spring 58 urges channel 38 in opposition to spring 42. Thus, it will be appreciated that the net frictional pressure exerted by channel 38 against the edge of the sash 25 is the difference between the pressure exerted by spring 42 and that exerted by spring 58. By tightening the screw 44, spring 58 will be compressed by the relative movement of the nut 138, so that the frictional pressure exerted by channel 38 will be reduced. Turning the screw 44 in the opposite direction will reduce the compression of the spring 58 thus increasing the net frictional pressure exerted by the channel 38 against the sash 26.

To remove the sash 26, as for example to facilitate cleaning thereof, it is merely necessary to urge the "sash laterally "against the pressure of spring 42 until the tongue 28 along the opposite edge of the sash moves free of groove 22.

When the window is closed, it is desirable that each sash cannot be removed in the manner last described. To prevent such removal, the lock construction shown in Figures 6 and 7 is employed in conjunction with each pair of mating channels 32-38. A recess or depression 53 is formed in the bottom of groove 40 as shown in Fig. 6. Positioned for movement in this recess is a plate 52 of a length about three-quarters ci" that of the recess. A channel bracket 64 is secured to plate 52 as by rivets J55 passing through slot G'i in the bottom of the recess `'53. The plate 32, lying fiush in the groove Gil, can be moved manually within the limits of the slot 51 and recess 6B, as shown by the drawings.

Adapted to cooperate with the sliding channel bracket 53 is a fixed stop 3S which is secured vby a rivet "it or other suitable fastening means to the inner face of the channel 32. The projecting edge of the stop 63 engages the projecting edges or channel bracket 53 when the plate 52 is moved to the locked position indicated in Fig. 6. This prevents movement of channel member 33 laterally against the spring or springs d2. When plate 32 is moved to the other extreme or open position opposite to that indicated in Fig. 6, bracket 5t is moved completely out of contact with stop thus permitting relative movement of channel 33 towards channel 32. Arseries of steps 69 of greater depth (see Fig. 6) are provided along the projecting edges of channel bracket 5t to permit locking of the movable channel 3S regardless of its relative position to channel 32 as may be produced by small variations in the over-all width of sash 2t or other dimensional variations from window to window. The lock assembly described is located near the center of the window frame, preferably in such a position that it will be covered by the sash frames when the sash frames are in their respective closed positions.

Each yieldable guide assembly 30 is rst assembled before being mounted in the window frame itself. In this assembly operation, channels 32 and 33 are iirst interlockingly engaged by sliding one over the other. Springs l2 are then placed in position through a hole I2 (see Fig. 4) in the channel 32. The hole 'i2 is just of sufcient diameter to admit the spring.

Brackets 5U and 52 are provided with anges 5i and 53 respectively, which are spot welded or otherwise secured to form a bracket assembly 56. After the spring 52 is position as described, the bracket assembly is placed in position by putting bracket 52 within the coils of spring 42 and inserting the flanges 5i and 53, which are of such size as to exceed the diameter of the hole l2, through the notches M (see Fig. 4) provided on diametrically opposite sides of hole 12. The bracket assembly 56 is then twisted through approximately ninety degrees to secure it in position. To further secure the bracket assembly 55 against movement perpendicular to the channel 32, the flange 5I is turned back, so that iange 5l and 53 engage the edge 0f the hole '.'2 on 'opposite faces of the bottom of .channel 32.

The spring 58 and the nut 58 are then placed in position as shown by the gure, and screw 44 inserted and threaded into nut i8 until the desired frictional pressure exerted by the guide member 38 against the edge of the sash 26 is attained.

Each yieldable guide assembly 3B is held in position-in the window Iframe at the IImi/'er end by means of an angle bracket 18 secured to the sill by means of screw 80. Channel 32 is slipped down behind the space between the side jamb and the angle bracket 18. The upper end of the channel 32 is shaped with a right angle nange 82. Screw 84 secures the ange 82 of channel member 32 at the upper end of the window frame. After the yieldable guide assembly 39 is in position, the window sash can be inserted by rst engaging it in the groove provided in channel 38, and then pushing laterally on the sash to compress springs 42 to the point where the tongue 28 on the opposite edge of the sash frame can be swung into position where it will engage groove 22 in channel I8. After the sash is moved into position, the lock is engaged by sliding plate 62 into position, preventing removal of the sash member. The frictional pressure of the movable guide assembly 38 is adjusted by means of screws 44 until the resilient pressure is proper to support the sash 26 in any desired vertical position without undue resistance to movement of the sash and, equally, without the sash slipping closed.

It will be recognized that the objects of my invention have been achieved by providing sash supporting means that are inexpensive in construction, which are readily installed and operated, and are weatherproof and long-lived, and yet which offer a wide range of adjustability. By the use of controlled frictional pressure7 the use of counterweights has been eliminated. The sash can be easily removed from either side of the Window frame by releasing a simple locking device and removing the sash from its guides. The features of my invention may obviously be incorporated with new or used window assemblies.

While in accordance with patent statutes, one best known embodiment of my invention has been illustrated and described in detail, it is to be particularly understood that the invention is not limited thereto or thereby, but that the inventive scope is dened in the appended claims.
