4 Claims. (01. 292-58) The present invention relates to certain new and useful improvementsin fastening means for double-hung relatively slidable window sashes and has more particular reference to means which is characterized by a keeper carried by'the upper sash and a retaining bolt which coacts therewith and which is carried by the lower sash.

These types of sash fasteners are aptly and satisfactorily used in the trade for burglar-proofing window constructions and are also notable in that they function as reliable anti-rattlers. The object of the instant adaptation is tostructurally, functionally and otherwise improve upon similarly constructed and performing prior art bolt-type fasteners.

Another object of the invention is to bring into use a fastener in the stated line of endeavor which, because of certain unique features which are embodied therein, will prove to meet ordinary requirements and needs of manufacturers and users alike.

Briefly summarized, the invention has to do with a retaining bolt, a novel bracket by means of which the bolt is stationed for use on an upper corner portion of the lower sash, keeper means for reception of the coacting end of the bolt, said keeper means being carried by the upper sash. In addition, there is a practical brace and this takes the form of a relatively movable bracket, the same serving to stabilize the intermediate portion of said bolt.

Other objects and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the accompanying drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a fragmentary perspective view illustrating a window frame and double-hung upper and lower sliding sashes therein and showing, what is most important, the sash fastening means constituting the subject matter of the instant invention.

Figure 2 is a view in section and elevation which may be said to be taken approximately on the vertical line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is a view like Figure 2 but showing the retaining bolt in its open or released position.

Figure 4 is a fragmentary perspective view of a modified keeper for the stated bolt.

Figure 5 is a fragmentary perspective wherein the form of the invention depicted in Figure 4 is slightly modified in order that it may be fas- 2 tened on the sash frame in a slightly different manner.

Reference is had to Figures 1 to 3, inclusive. In Figure 1 the window frame, as an overall structure, is denoted by the numeral 6 while the lower slidingsashis denoted at 8 and the upper sliding sash at H]. These are, of course, conventional parts of a window. The sash ill, in order to accommodate the present invention, is formed in one of its vertical rails, adjacent the lower lefthand corner, with a recess or mortise which is provided with keeper means. The keeper means in this instance is a simple metal or equivalent cup 12 which is fitted into the mortise and which functions as a socket member.

The stated bolt is denoted by the numeral [4 and this comprises a suitably threaded stem or shank 16 having a smooth terminal end I8 constituting a detent, the latter fitting telescopically and removably into the keeper socket or member. There is a stop flange 2D dividing the detent from the threaded portion of the shank. This flange is of a larger diameter than the socket member and not only abuts the sash but covers the socket member and provides a satisfactory association of elements. The left-hand end portion of the bolt is provided with a suitable finger-grip 22.

The bracket which mounts the bolt is a simple device and is denoted by the numeral 24. It comprises a post-like upright 26 having projecting base forming lugs 2828 atits bottom. This upright is preferably rectangular in cross-section and has a screw-threaded passage extending therethrough which thus transforms the upper end of said upright into what may be called a nut for the bolt. It will be noticed that the base is provided with a central depending screw-threaded portion which constitutes an anchoring screw 30 and this is, more specifically, a wood screw. Thus, the bracket is simply screwed into place at the desired point in order that the detent on the bolt will line-up with the keeper socket on the upper sash, as shown best in figure.

In order to relieve the bolt of shearing strain and to stabilize the operation of the same and to insure longer lasting alignment between the bolt and socket member, a brace is provided and this takes the form of a relatively movable bracket 32 which, in many ways, resembles the bracket 24. Here again, an upright 34 is provided and this has projecting base elements or lugs 3-5 and there is a hole 38 through the upper end portion which lines up with the aforementioned nut. The hole 38, however, is smooth and of a diameter larger than the outside diameter of the bolt.

Hence, the bracket or brace 32 is freely slidable in relation to the bolt and vice versa. It is undesirable, it is believed, to actually fasten this bracing bracket 32 to the sash. Therefore, it is free of attachment and may be slid to assume the best usable bracing position which is usually that shown in Figures 1 and 2. There may be instance, however, when it is desired to retract the bolt to the extent shown in Figure 3 and in this situation the flange 20 engages the bracket 32 and drags same toward the fixed bracket 24. Thus, there are spaced parallel perpendicular brackets, one of which is fixed as at 24 and the other one being slidable, this being the bracket 32. These two brackets coacting with the simple bolt provide an unusually satisfactory and reliable assemblage of parts.

If one does not desire to use the keeper socket l2, he may dispense with the same and employ, in lieu thereof the type of keeper means shown in Figure 4. The latter means comprises a fixture which is denoted at 49 and which takes the form of an attaching plate 42 secured by fastening screws or the like 44 to the rail of the sash Hi. The plate projects and has its projecting end formed with a passage or hole 46 for the bolt which lines up with the sleeve 48 which latter constitutes a socket member. Thus, in both keeper constructions a socket member is a common characteristic.

Reference is now had to the third form or adaptation of the invention. This form of the invention is closely allied with that revealed in Figure 4. As a matter of fact, the two figures are practically the same except that in Figure 5 the fixture 40a instead of being in the form of a flat plate 42 is an L-shaped plate. The plate portion is denoted here in this figure with the numeral 42 and the laterally bent end portion is rounded and denoted by the numeral 420.. Otherwise, the fixture or bracket is the same in that it includes a hole for the bolt 46 and a line-up sleeve 48 which registers with the hole. By reason of this L-shaped fixture the latter may be placed in a mortice or groove provided in the bottom rail of the window sash and screwed or otherwise anchored therein.

In practice, the nut forming and anchoring bracket 24 is screwed into place at about the position shown and this locates the bolt where wanted. The rail of the sash i0 is mortised and the keeper socket member 12 is fitted into plate. With the bolt and socket member properly lined up the detent I8 may then be projected into the socket member for locking the sash 8 with the sash [0 in an obvious manner. The intervening relatively shiftable bracket 32 is primarily a sta- '4 bilizing brace. By having the brace the over-all fastener is thought to be not only more rigid but virtually jimmy-proof.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more length description is regarded as unnecessary.

Minor changes in the shape, size, materials and arrangement of parts may be resorted to in actual practice without departing from the spirit and scope of the invention, as claimed.

Having described the invention, what is claimed as new is:

1. A sash fastener comprising a bracket having a base provided with a depending wood screw, an upright rising from said base, said upright being polygonal in cross-section and provided with a screw-threaded bolt hole, a bolt screwed through said hole and having a finger-grip to one end, having a smooth detent at the opposite end and a stop flange adjacent said detent, and a second relatively movable bracket having a base adapted to rest slidably on a portion of a cooperating sash frame member and also having an upright rising from said base, said upright being of a height conformable with the height of the first named upright and having a smooth-walled bolt hole therein, that portion of the bolt between said stop flange and first named upright extending freely and slidably through said smooth-walled hole.

2. The structure specified in claim 1 in conjunction with a plate having a. portion attachable to a sash, said plate also having a fiat portion adapted to assume a position in spaced parallelism in respect to said respective uprights and provided with a bolt opening for reception of said detent and a sleeve aligned with said opening and providing a socket into which said detent projects and is accommodated and held.

3. The structure specified in claim 2, wherein that plate portion is wholly flat.

4. The structure specified in claim 2, wherein said plate portion is substantially L-shaped in edge elevation.
