WINDOW FASTENER Filed NOV. 26, 1928 ATTORN BY,

Patented Oct. 13, 1931 PATENT OFFICE j PETER J. WESOLOWSKI, F DETROIT, MICHIGAN WINDOW FASTENER Application filed November 26, 1928.

This invention relates to window fasteners and more particularly to a combined fastener and latch construction including means for securing the window sections in rela- H tively adjusted positions.

The invention has an object to simplify, render more efficient, and improve generally constructions of this type-and these, as well as other objects, advantages, and the novel details'of construction will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein Figure 1 is a fragmentary perspective view of a windowwith my invention attached thereto;

Figure 2 "is afvertical' sectional view through the device;

Figure 3 is a sectional elevation taken substantially on thezplane indicated by line 33 in Figure 2; and

Figure '4 is a fragmentary elevational view of the link and its support.

" Referring now particularlyto the draw- 1 ings wherein like'reference characters indicate like parts, it will be-noted that there is illustrated the adjacent rails and 11 of two window sashes preferably of the vertical slidabletype which are movable in the man'- Nm ner suggested in Figure 1 for opening the window and assume the position shown in Figure 2 when-closed. that is with their rails 10 and lladjacen'tone another.

r My improvedwindow fastenerconsists essentiallyof a bracket 12 adapted to be secured to the rail 10 of one'of the sashes, this bracket consisting of a base plate 13 and an uprightportion 14: The bracket 12 has a dual vfunction of constituting a support for the r connectinglink or arm 15 and of constituting a keeper plate for thelocking element of the fastener. The link or arm 15 is in the form of an elongated plate member provided with a longitudinally extending slot 16, the member 15 being also formed with a lateral ear at one end thereofthrough which is passed a rivet or y stud 17 which also extends through the up right portion 14 of bracket 12 for pivotally securing link 15 thereto. The upright por- Serial No. 321,935.

tion 14 of bracket 12 is also provided with a cutaway portion forming a keeeper slot or recess 18. the base 13 of the bracket being also preferably cut away as at 19 to facilitate the engaging of the locking element yet to be re 58 ferred to. The slot 16 of link member 15 is provided with an enlargement 16' at the end thereof adjacent its pivotal connection to the bracket 12.

Mounted on the rail 11 of the other sash section is a complementary latch or fastener member indicated generally by the reference character 20. This member consists essentially of a base 21 and a housing 22. The base portion 21 provides means for attaching this fastener member to the rail 11, as for instance by means of screws or the like 23. Mounted in the housing portion 22 and extending therethrough is the shaft 24 of a locking element. One end of shaft 24 is provided with a head having an annular groove 25 and consisting further of an angular crank or arm 26 and a laterally bent end or projection 27. The other end of shaft 24 is provided with cam member 28 adapted for engagement with a cam surface 29 formed on the housing 22 and an operating handle 30. Surrounding the shaft 24 and arranged within the housing 22 is spring 31 which bears on the one hand against a wall of the housing and on the other hand against a shoulder 32 formed on shaft 24. This spring acts to norrnally project the head of the locking member outwardly from the housing 22.

and 11 are thus completely closed and locked against relative movement. Upon rotation of the locking member to disengage the projection 27 from the keeper recess 18 the sashes may be relatively moved and thus one of them opened a distance corresponding to the length of slot 16 as will be obvious. When one of the sashes has been thus adjusted the sashes may be locked against further relative movement by rotating handle 30 of the locking element, whereby the arm 26 is brought to bear against link 15 so as to clamp the link between the head of the locking element and the housing 22. This clamping action results from the engagement of cam 28 with the 1 cam surface 29 on the housing. this cam action axially displacing shaft 2% against the action of spring 31 to thus clanfp the link 15 in the manner above described.

The wall of housing 22 is formed with a 15 slot 33'through which the head of the loekini;

element may be withdrawn by axiallydisplacing shaft 24 against the action of spring 3f..- Thus if the link 15 is so moved as to poh sitionithe slot 16 thereof parallel with slot 33 the two fastener members may be disconnect ed the enlargement 16" of the slot 16 permit withdrawal of the head of the lockingeIement. With the fastening: members tlmsdisconnected the sashes can be opened a tetheiullextent provided for by their constmction.

From the foregoing it will be immediately apparent that the above described window 1 Mien!!! not'only constitutes means forposi fively locking'the sash sections in completely elbsed ion but also provides means for l'ockiig the sash sections in adjusted positions. 1 It will be understood that in practice tllol'ink I5 will preferably be of a lengtl'i which will permit of a relative adjustment of the sash sections to open position a distance insulficimt to permit the unauthorized endream of a person through the window openso that irrespective of the clamping action: between the link and the complementary men section 26' entrance through the window opening could not be' gainedby raising or flowering either of the sash sections. How o'ler, the sash sections may be raised or lowcred and secured in their adjusted position by the clamping engagement of head of the looking element upon link 15 thereupon positively preventing any furtherrelative movement of the sash sections and also preventingany rattling of the sections. By disconnecting thQ fme! sections the sash sections may be opened as desired. 7

'While the invention has been illustrated as q em ed in connection with sashes. it will fbt! obvious that it may be employed with equal facility in connection with various other closures, as for instamce transoms and the like. 7 A The construction of the several parts constituting my improved window fastener is cult that they may be cheaply, quickly, and dumbly manufactured at a minimum cost and may be installed with facility without 'ring the services of a skilled mechanic.

ile one specific embodiment of the invention has been illustrated and described in some detail, it will be immediately apparent that various modifications in the specific structure illustrated may be resorted to without departing from the spirit and scope of 70 this invention, and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.
