vMy invention relates to friction latches for n'findovfs and more particularly to a silent latch that has a friction grip which will hold a window in any desired position objects and advantages will be fully er.:- plained in the following description andy the invention will be more yparticula'rl;4 point-ed out in the claims.
Reference is had to the accompanying rdrawings which form a part of this application. n
l1 ig. l is a front elevation of a Window equipped with lthe improved latch. F 2% is a. broken view of the right side of the sis-1h, showing the tension springs and the bearing strip. Fig. 3 is a view of a flat piece of metal before it is bent to form'the bearing strip. Fig. lis a view of a. flat piece of metal before it is bent to form the gripping member. Fig. 5 is aside elevation of the gripping member. Fig. G is an edge view of the same. F ig. 7 is a` perspective view of the upper tension spring. Fig. 8 is a perspective view of the lift or handle for raising or lowering the window. Fig. is a horizontal section, taken on the line 5)*9 of Fig. 1.
Similar characters of reference are used to indicate the same parts throughout the several views.
'lhe `frame members 3 and move vertically andr freely against the members 1 and 2 respectively. rlhe 'vertical guide keepers 5 are attachedv to the window frame in the usual manner but these guide keepers are beveled as shown in Fig. 9. rlhe improved silent friction gripping members are applied to the sash frame and to\the Window frame to form operative connections, and the object is for adapting the gripping devices for adjusting themselves automatically to gripping positions.
Bearing strips 7 are attached to the sash frame members 3 and t and these strips 7 afford the necessary friction for the gripping arms 6. Thestrips 7 are further made rigid with the sash frame vmembers by angular extensions 8 which are bent at right angles to the strips and countersunk in the edges of the sash frame. A pressure spring 9 attached to the bearing strip 'i each yside of the sash frame and secured in place by a tongue or lip 1() .vhich sprung ontof the plane of the body of extention 8. rlhe springs 9 exert te n and tend topress the sash away from the Windev.Y :ame towards the central partof the window. This tension will make a griliiping action againstthe.window frame for locking the sash at different heights.
The friction of the spring against the window frame will be sur'iicient to hold the sash what ever height desired. lt will be understood that the spring on the opposite side ofthe window functions in the saine manner.
A tension or pressure spring 11 is provided for each upper corner of the sash. .',l'he` lower end of the spring 11 is made stationary with the sash by means of a lug 13 on the spring whichs inserted in the slot 12 in the member 8 of the bearing strip. rlhe spring 11y has a socketv 14 which receives a lug 15 which is rigid with the ygrip arm 6. Thesash frame is morticed vto make pro- `vision for swinging or movngthe spring 11.
Thebearing strip 7 has an elongated opening 16 so that the arm 6 will have a limited movement.l The obj ect is to malte the gripping arm adjustable aty the upper end. The arms 6 are pivotally mounted by the lugs 15 it Vbein@- understood that similar arms G are on both sides of the sash. The springs 9 and 11 take Careof the lateral movement of the sash. o
rllhe inward or outward movement of the sash is taken care of by the angular Wings or Wedges which are formed on the edges of the grip arms 6. The guide keepers 5 are beveled to make a wedge shape and the members 17 are forced against the guide keepers 5.
For operating these arms 6, they are provided with inwardly projecting extensions 1S at their lower ends. rlhe sash lifts 19 are attached to the base of the sash and the lifts have ears formed thereon and bent down to form guides 2O for the extensions 18 which will move freely behind the ears 2O in their lateral movement. These eX- tensions are provided 'with operating lugs 21. In operation, grasp the lugs 2l and press them towards the central portion of the sash with suflicient force to overcome the tension of the spring 9 and draw them suiiicientlyl away frein the beveled guide keepers 5 and iroin the sash traine inen'ibers 3 and ai and that the friction members l? so that the gripping arins 6 will release the guide lrcepers Hold the ineinbers (i free frein the guide keepers 5 and the inembers 3 and while adjusting the sash to the required position. fvlnen the desired position for 'the shash is reached, release. the lugs 2l. The springs 9 and li will force the grip arms 6 against the stops 5 and bearing inenibers and thus grip the sash at the desired elevation. A lug 22 catches on the spring 9. rihis lng 22 is integral with the grip arin 6 and it constitutes the ine-ans by which the grip arin 6 is drawn to operative position by the spring 9. The upper ends oil the grip arms 6 are operatively connected to the spring ll by nieans or' the lug 15 and the socket 11i oit' the spring ll. rEhe spring 1l is prevented frein displacement by lugs 23 and 241 strucl; Jrroin 'the bearing strips 7. The lng 2i acts as a stop or guide against which the soclret 11i will stop. The lug is loosely engaged by the grip a in and the tension otl the spring is obtained by this lug `for adjusting the grip arin 6. The stops 19 are provided with lugs 25 which serve as rests or bearings for the lingers when other lingers engage the lugs 2l, in the act oitl operating the grip arins 6.
W hat I claim7 is,-
l. Friction grip window latches comprising in combination with a window traine and a sash frame, beveled guide keepers 'attached to said window ranie and bearing strips atached to said sash frame, a pair of friction arms operatively connected to said bearing strips at their upper ends and positionedbetween said guide keepers and said sash :traine and provided with wedging members engaging said beveled guide heepers substantially throughout their length, and tension ineans attached to said bearing strips 'or forcing said friction arnis between said stops and the sash.
2. Friction grip window latches comprising` in combination with a window 'f1-aine and a sash traine, beveled guide keepers attached to said window traine and bearing strips attached to said sash traine, a pair ot inenibers integral therewith substantially friction arins having elongated wedging throughout their length, said bearing strips having elongated slots in their upper ends,
springs attached to said bearings strips and provided with lugs projected through said slots ior engaging and holding said friction arms in operative position and for forcing said arins between said guide keepers and friction arms having elongated Wedging sash, said arnis having lugs near the lower ends thereof, springs attached to the lower -nds of said bearing strips for engaging said lugs and co-operating with the lugs oi' said sp1-ii Y at the upper ends of said strips, and means on the lower ends of said arms for releasing the grip of said arms.
In testimony whereof. I set iny hand7 this 27th day or' March, 1926.
