SASH HOLDING DEVICE Filed Dec. 16, 1947 I 2 Sheets-Sheet 2 Patented May 24, 1949 UNITED STATES PATENT OFFICE SASH HQLDING DEVICE Ernest E. Montgomery, Gering, Nebr. Application December 16, 1947, Serial No. 791,969

2 Claims.

This invention relates to sash holding devices.

An object of the invention is the provision of a sash holding device in which a bar or plate not only holds the sash in an adjusted position but prevents rattling thereof while acting as weather-stripping.

Another object of the invention is the provision of a sash holding device in which a member is suspended by a spring to each side stile of a sash for limited movement thereon so that when the sash is raised, means carried by the member will force said member outwardly against elements of the window casing for not only retaining the sash in position but for preventing rattling of said sash.

A further object of the invention is the provision of a sash holding device which may be installed readily to the side stiles of a sash and which may be adjusted easily without removal of the sash, the holding device including an element having limited movement relative to the side stiles of the sash upon which the element is suspended for causing the element to move laterally from the associated stile and retain the sash against downward movement and rattling.

The invention consists in the novel construction, arrangement and. combinations of parts hereinafter more particularly described and claimed.

In the drawings,

Figure 1 is a view in perspective of a sash holding device shown detached from a sash,

Figure 2 is a view in perspective of a modified form of sash holding device, shown detached,

Figure 3 is a view in perspective of the form of sash holding device illustrated in Figure 1, shown applied to a side stile of a sash,

Figure 4 is a view in perspective of the modified form of the sash holding device shown applied to a sash,

Figure 5 is a horizontal section of one side of a window casing showing the sash holding device of Figure 1 applied to the lower and upper sash, and

Figure 6 is a fragmentary horizontal section of a casing showing the application of the modified form of sash holding device applied to a sash.

Referring more particularly to Figures 1, 3 and 5 of the drawings l0 designates a metal plate or bar extending for substantially the length of a side stile ll of a sash l2. A flange I3 projects inwardly from a side edge of the plate and embraces the front face of the stile which has the usual groove l4 for receiving the cord that suspends the sash. However, when the holding device is applied to a sash which does not have such groove, a groove must be provided.

An anchor plate I5 is driven through the groove it at right angles to the length thereof and into the side stile ll (Figure 3). This plate is provided with a passage I 6 to receive slidably a bolt ll threaded at [8 for a nut [9. A coil spring 20 on the bolt has one end abutting a head 2| while the other end engages the anchor plate [5. Said head is provided with a slot 22 to receive a screw driver.

An inturned lip 23 on the upper end of the plate as has a passage 24 to receive the lower end of the bolt l! with the nut l'9 in contact with the under 'face of the lip. The diameter of the passage 2d is such that the bolt may move freely in said passage. The lower end 25 of the bolt is enlarged to prevent loss of the nut from the bolt. One side edge of the nut engages flatly the inner face of the plate It to prevent turning of said nut when the bolt is revolved by a suitable instrument for adjusting the position of the plate as will be explained presently.

Expanders 39 in the form of links are pivoted on rivets 3! in spaced relation along the length of the elongated narrow plate l0. Each expander is inclined at an acute angle to a horizontal plane passing through the rivet 3|. The upper end of each expander has an opening to receive a nail 32 which is driven into the stile H and through a tapered passage 33 formed in the plate Ill. The nails have round heads 34 and the diameter of said heads is less than the diameter of the passages 33 for a purpose which will be explained presently. Screws having round heads may be employed instead of the nails.

An angle iron track 35 may be used, if desired, in connection with the plates Ill. The track (Figure 5) is secured at 36 by nails to the side jamb 31 of the window casing with the free flange 38 of the track in contact with a bead or blind stop 39 of the casing. A partitioning bead 40 is fitted into a longitudinal groove in the side jamb of the window casing and separates the upper sash [2 from the lower sash l2a, A strip of molding 4| abuts the inner face of side stile of the lower sash.

The side stile of the sash 46 in the modified form illustrated in Figures 2, .4 and 6 must be rabbeted lengthwise at 41 adjacent the blind stop 39 carried by the casing 31 to receive a bar or plate 48 which has a slight movement relative to said stile. Said bar is provided with a longitudinal slot 50 at the inner edge and is cut away at the upper end as shown at 5|.

An elongated bar 52 has a longitudinal slot 53 facing the slot 50 in the bar 48. The outer face of the bar 52 is flush with the faces of the bar 48 and a shoulder 54 formed by rabbeting the stile 45, The bar 52 is secured by nails 49 to the side stile of the sash. The bar 48 on the other hand, corresponds in function with the plate or bar ID in Figures 1, 3 and 5.

The bolt I'I, nut l9, spring 20 and the anchor plate l5 are identical in construction with the corresponding elements shown in Figures 1, 3 and 5 and perform the same functions. However, the method of attaching said elements to the adjustable bar 48 must be modified to conform to the variations in the modified form. For this purpose, a bracket 55 is provided with a depending flange 56 received by the aligned

slots

50 and 53 in the

respective bars

48 and 52. Said flange is secured at 51 only to the bar 48. A lip 23a on the bracket 55 has an opening 24 to receive the bolt H. The anchor plate I5 is driven into the side stile of the sash through the cord slot it. The cut away portion 5i provides for a clearance between the plate l5 and the upper end of the bar 48.

Expanders 69 in the form of links are pivoted at the lower ends on rivets 5i carried by the bar 48. Said expanders are inclined at an acute angle to a horizontal plane passing through the rivets iii. The nails or screws 49 which fasten the bar 52 to the side stile 45 pass through perforations in the upper ends of the expanders 63. It will be noted that the expanders are located in the aligned

slots

55 and 53 so that they are concealed completely.

The operation of my device is as follows. After the holding device shown in Figures 1, 3 and 5 or the modified form illustrated in 2, 4 and 6 has been applied to the sash as described, and after the sash has been replaced in the window casing, the head 2! of the bolt is turned in the proper direction to cause the bar l0 (Figure 1) or the bar 48 to be shifted laterally by the associated expanders 38 or the expanders 50 so that the flange 13 of the bar It or the outer edge of the bar at will have sufiicient frictional contact with the member 39 of the window casing to retain the sash in an adjusted position, while permitting ready movement of the sash. The bolt l'l may be revolved without requiring removal of the sash.

When the bolt I! (Figure 1) is revolved, the plate IE3 is raised or lowered and the expanders 30 swing on the nails 32 so that the plate It and the attached flange l3 will be moved laterally. This is also true of the bar 48 wherein the expanders 63 force said bar outwardly or inwardly of the fixed bar 52 and towards or away from the member 39 of the window casing.

The bars 48 and 52 (Figure 2) may be made of wood, a metal or a plastic or the holding device may be manufactured wholly of metal. In any event, the holding devices illustrated in Figures 1 and 2 perform a triple function in that said device will not only retain a sash in any adjusted position but will act as weather-stripping while preventing rattling of the sash.

I have shown the holding device applied to one side stile of a sash. Nevertheless, said device may be installed on both side stiles of the sash. In this case, a more complete weather stripping is provided while creating a more perfectly balanced sash.

What I claim:

1. In a window sash having a groove in a side stile thereof, a sash adjuster comprising a bar running the length of the stile, means supporting the bar for limited sidewise movement on the stile and spaced expander links having pivotal connections with the bar and with a fixed portion of the stile, said links being inclined at an angle to the horizontal, said supporting means including an anchor plate driven through the groove and into the side stile and provided with a passage, a bolt slidable in the passage and having a head at one end, a coil spring on the bolt between the head and the anchor plate, said bolt having threaded connections with the bar so that when the bolt is turned the bar will be raised or lowered causing the links to move the bar sidewise towards or away from a blind stop of a window casing.

2. In a window sash having one corner of a side stile rabbeted to provided a vertical channel, a bar having a sidewise shifting movement in the channel, said bar having a longitudinal groove in the inner edge, a second bar in the channel secured to the stile and having an edge provided with a groove aligned with the groove in the shiftable bar, inclined links in the aligned grooves, one of the ends of the links being pivoted on the shiftable bar, the other ends of said links being pivoted on the fixed bar, a bolt slidably mounted on the stile, a spring tending to maintain the bolt elevated, and threaded connections between the bolt and the shiftable bar, turning of the bolt causing raising or lowering of the said bar so that the links will move said bar towards or away from a blind stop on a window casing.
