SCHAFFERT CLOSURE OPERATOR AND LOCK Filed Dec. 8. 1951 2 Sheets-Sheet l "are 2 Sheets-Sheet 2 Filed Dec. 8, 1931 awe/whorl Patented Sept. 27, 1932 UNITED STATES PATENT critics ADOLF H SCHAFFERT, O13 YOUNGSTOWN, OHIO, ASSIGNOR- TO TRUSCON STEEL GOM- PANY, OF YOUNGSTOWN, OHIO, A CORPORATION OF MICHIGAN CLOSURE OPERATOR AND LOGK Application filed December a, 1931 Serial No. 579,764.

In connection with swinging sashes, vents or other closures, and particularly those which swing outwardly and wlth whlch fixed screens are employed, it is very desirable that means be provided for positively locking the closures when in open position, for there is danger when high winds or sudden gusts oc cur, that they will be slammed sometimes with suflicient force to break the glass or the hinges.

The object of the present invention is to provide a structure of this character which is highly effective, and at the same time is extremely simple, so that the sash may be held in various positions, and even if it should occur that in a certain position it is not positively locked, it can only move a short distance before it becomes so locked.

In the accompanying drawings: 1

Figure 1 is a horizontal sectional View through a frame and swinging sash showing the novel holding means applied thereto.

Figure 9 is a detail sectional view on the line 99 of Figure 1.

In the embodiment disclosed, the win dowframe is shown at 10, and hinged to one side of the same, as illustrated at 11 in Figure 1, is a swinging sash or vent 12. The frame and vent are shown as of deformed metal, though the material of which they are constructed is relatively unimportant.

Secured to the inner side of the lower cross bar of the frame is a casing which consists of a base plate or bottom wall 13 having upstanding ears 14 on its rear side engaged by screws 15 that serve to secure the casing to theinner side of the frame bar. The distance between theears 14 as shown. in Figure '3 marks the length of a slot 16 formed in the framebar 10. A top wall'17 is provided with side flanges 18 forming the side walls of the casing and these flanges have suitable lugs 19 that pass through openings 20 in the base plate 13 and are upset, thereby securing the casing members together. The side walls 18 have portions cut away to provide an opening 21", which with the space between the ears 14 of the base plate, provides a transverse passageway through the casing.

In this passageway isslidably and swingingly mounted a sash-holding bar 22 which is channeled as shown at 23 and at its outer end has a pivotal connection 24 with a bracket 25 secured to the swinging sash 12. The bar 22 is guided in its movement through the easing by an upstanding post 26 fixed to the bottom wall 13 and having a socket 27 opening through its upper end. This post as clearly shown in Figures 4 and 8 is engaged in the channel of the bar and therefore constitutes not only a slide guide but also one on which the bar has a pivotal movement. The inner end of the bar 22 is preferably provided with an upstanding finger piece 28f0rmed by an angle piece, one arm 29 of which is fitted in the end'of the channel 23 of the bar 22 and is secured by any suitablemeans as a screw The top wall .17 has fixed thereto an upstanding cylindrical shell 31 in which is slidably mounteda plunger 32 carried by a stem 33 that projects above the shell and has a finger piece 34. A coiled spring 35, located in-the shell 31 and pressing on the plunger 32, urges it downwardly. The lower end of the plunger is in the form of a stud 36 that is adapted to pass through any of a series of openings 37 formed in the holding bar 22 at various points along the same. The stud 36 moreover is adapted to engage in the socket'27 of the post 26, as will be clear by refer-e ,ence to Figure 4.

It will beevident that with this structure, if the plunger is raised, by. raising the finger piece 34the stud 36 Willbe disengaged'from the socket 27 and will be elevated above the bar 22. Consequently the bar can then be freely operated and the sash swung in either direction. When a desired position has been obtained and the plunger is released, if one of the openings 37 of the bar is in line with the stud 36, said stud will pass through such opening and into the socket 27. The bar will thus be positively looked as clearly shown in Figure 4 and the sash will be just as positively held against swinging movement. Should it happen that none of the openings 87 is in line with the plunger, said plunger will then rest on the bar, but it will be evident that if the sash moves the bar will be correspondingly moved and the first opening that registers with thelstud will receive the same and consequently automatically lock the sash against further movement. p

The structure is simple and effective and not onlycan be manufactured at relatively small cost, butis readily installed.

I From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in. the art without further description, and it'will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

way, and a plunger mounted in the casing and engaging the bar to secure it.

5. A closure operator and lock comprising a mounting member having a passageway, a post located in the passageway, a channeled closure operating and holding bar slidably extending through the passageway and hav ing its channel slidably receiving the post, and means that engages the bar to secure it against movement.

6. A closureoperator and lock comprising a mounting member having a passageway, a post located in the passageway, a channeled closure operating and holding bar slidably extending through thepassageway and havand means that engages the bar and the post to secure 1t against movement.

In testimony whereof, I aifix my signature.
