Application April 21, 1933. Serial No. 667,301

2 Claims.

My invention relates to fasteners for window sashes of the casement or French type, and my main object is to provide a fastener by means of which the window sash can be tightly closed. A further object of the invention is to design the fastening means which is effective at points intermediate the upper and lower ends of the window sash, whereby to apply and fasten the same evenly to the jamb or stop. I

A still further object of the invention is to provide fastening means involving the principle of a cam, whereby to procure sufficient pressure to close the window sash tightly.

Another object of the invention is to construct the fastening means with a control which has a high leverage over the immediate fastening element, makingit easy to operate the same.

An additional object of the invention is to operate the novel fastener by means of a gearand-rack mechanism which secures positive action' and is devoid of delicate parts.

A significant object of the invention is to provide a bearing support for the fastener operating mechanism which is simple, compact and efficient.

With the above objects in view and any others that may suggest themselves from the specification and claims to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Fig. 1 is an elevation of a set of the novel fasteners as applied to a typical casement window installation;

Fig. 2 is an enlarged fragmental view of one of the fasteners and the control therefor;

Fig. 3 is a section on the line 3--3 of Fig. 2; and

Fig. 4 is a view similar to Fig. 3 showing the fastener in a different position.

Various expedients have been employed to procure the fastening of casement and French windows, but in many cases the fastener does not tightly close the window sash or requires a complicated mechanism in order to be efficient. In some cases, several fasteners are used along the height of the window sash and have to be separately manipulated in order to fasten the same securely. In other cases, a single control is employed effective to bolt the window sash to its frame at thetop and bottom. In this case, it often occurs that pressure or warping tendencies cause the intermediate portion of the window sash to become deformed to the extent that it does not close upon the jamb or stop when the upper ends of the window sash do, rendering the fasteninginsufiicient. To relieve the above difficulties, I have constructed the novel fastening means along lines of simplicity, rigidity and multiple application with a single control, whereby to fasten the window sash securely along its entire height.

In carrying out the invention, specific reference to the drawing indicates a typical casement or French window at 10, and the frame jamb or stop against which it closes at 11. Instead of employing fastening means at the top and bottom of the window sash, I apply two or more fasteners at points intermediate thereof, two fasteners being shown.

Each fastener is built upon a base plate 12, the latter receiving a reinforcing. plate 13 from above. and screws 14 being driven through both plates to secure them rigidly to the window stile 10. The upper plate 13 .is squarely arched in the middle, as indicated at 13a to facilitate the sliding travel of a bo1t15 having a bevel point 15a at its forward end. The bolt 15 has a flat bottom in sliding contact with the plate 12, but the upper side of the bolt is made with a gear rack 15b.

Above the rear portion of the bolt 15 is located 90 a rod 16 to which is fastened by cross pins 17a or other suitable means a sector pinion 17, this pinion being in mesh with the rack portion 15b of the bolt. The base plate 12 is extended on both sides of the sector pinion 17 with upward strips 12a which are bent upwardly from the rear ends of the plate, these strips being rolled forwardly around the rod 16 to form bearings 12b therefor. The edge of the jamb or the stop which faces the window aperture receives a keeper plate 1 18 by means of screws 18a, this plate extending into the room with a slight curvature away from the window sash as indicated at 18b, and the curved section having a slot 180 in line with the bolt 15 when the window sash is closed.

A fastener unit of the type described above is provided in the two or three places mentioned, and the rod 16 made of such length as to be common to all of the fasteners. The rod receives additional bearings 19 at points where support may be necessary, and is fitted at the middle with a sleeve 20 secured to the rod by set screws 21, and having an outwardly extended handle 22 of the arched type.

Figs. 1, 2 and 3 show the bolt 15 in each of the fastener units advanced and the window sash securely fastened. However, it will be apparent that by swinging the handle 22 in the direction of the arrow in Fig. 3 to the extent shown in Fig. 4, the gearing will be caused to withdraw the bolt 15 and permit the hand which has operated the handle 22 to draw upon the window sash with the effect of opening the same. This action is facilitated by the fact that the handle 22 extends in the opening direction of the window sash when it has been swung as described, making the pull upon the window sash immediate and direct.

It i,- er m'sdateqst ot e l hs ee nt olr, formed byltheliaigdle 22 ;and thwrodglddsgof a nature to operate any number of fasteners along the height of the window, and imparts the same action to all of them. Therefore, the window sash is not only fastened at the top and bottom but in as many intermediate places as is COIlfiideIBd:fldn'- visable to assure the uniform application1 ofjghe window to the jamb or stop.

It is apparent that the curvature of the keeper plate 18b is intended to leadi-the boltnbacketoa 1.- position of origin as the window sash is closed in case the bolt happens to be projected some-- hat romit uide-"W en-t elw nslow ashihas 9. beenfc osedi; el wihep sthe handle 1 2,11 1. e.- ectiqnip ii e .-z nd w shm llsad ance eibolt, withl hae fi o i imoy nsli abet led H p int .ciains. ...t e.outeniedeelo i; helmene slot 180 in the manner of a cam, so that when; etb lt a u. l ntieltedthee otathe.saidisam tiohehasimnarted.asufiiqientmtessure'tolthe. n w a h-t c qsiei hes m ..ti htlwasainstthel s ve ase..unqnet e bolt-1.. solethati l tt elmanualw;

Secondly, these bearings eliminate the need of a housing to form a bearing for the rod, thereby reducing the height of the mechanism above the surface of the stile 10 and enabling the rod 16 to be laid as close to the window stile as the mechanism will permit. This feature makes the installation compact, simple and inexpensive. Furt e t e echani ofutheia teneram its multiple control is almost-entirely carried by the window sash, so that very little of the hardware is seen on the jamb, and the mechanism does not detract from the appearance of the window or appear conspicuous. Finally, it will be evident thatsthe par-ts of the installation are simple and rugged,. a'ndthattheymay be made and assembled at, small expense.
