Patented May 20, 1930 UNITED STATES PATENT orece 'RAYMo'NnLQGREIsr, or CHICAGO, ILLINOIS, ASSIGNOB. TO THE ADLAKE COMPANY,

V CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS i .sAsII GUIDE v I Application. filed. November 15, 1928. Serial No. 319,509 r This invention has to do with sash guides of the detachable side Wall type disclosed in Patents Nos. 1,659,657 and 1,659,658, and is particularly concerned with the'manner in which the detachable sidewall of the guide is held in position. 1

The purpose of theinvention is to provide, in a guide of the type'described, improve ments for holding the detachable sidewall in position. p I v i In order that the invention may be readily understood, one form of the same is presented herein, but it will of course be appreciated that the invention is susceptible of embodiment in other structurally modified forms coming equally within the 'scopeof theclaims.

In the; accompanying drawing:

Fig. 1 is a front view of thelower end of a sash guide equipped with the latchof the invention;

Fig. 2 is an inner side view; I

Fig. 3 is a rear view; I

Fig. 1 is a vertical section, taken on the line 44 of Fig. 1; and

Fig. 5 is a horizontal section, taken on the line 5-5 of Fig. 2. y g

The sash guide shown in the drawing is characterized by a fixed strip and a detachable strip 11. The striplO is adapted to be fastened to the jamb of awindow frame by screws or other suitable means and is provided at one side with a groove 12 and at the other side with a fixed side wall-13. If it is desired to have a 'guide from which a'sash may be removed from either side, the fixed side wall 13 is dispensed with, and another groove, similar to the groove 12, is provided at that side of the strip in place of the fixed side wall. r

The strip 10 is made of sheet metal, and

is bent in such a way as to form the groove 12, the fixed side walls 13 and an intervening Web 14. The strip 10 obviously maybe bent in a great many other different ways to provide the portions described.

The strip 11 constitutes a removable side wall opposite the fixed side wall 13 of the strip 10, and is seated within the groove 12 in the strip 10. The portion of the-strip 11 within the groove is preferably provided with a springstrip 15, which is soldered or secured in any suitable, fashion to the inner edge of the strip and extends at an angle from the same. I

When the guide is not occupied by the stile of a sash, the strip 11 will assume the canted position shown in Fig. 5 under theaction of the spring 15, but, when the stile of a sash is in place in the guide, the strip 11, upon being inserted in the groove 12 in the strip 10, will be held by the stile of the sashin a position generally parallel to the fixed side Wall 13 of the strip 10, in which-position the strap 11 will be pressed resiliently againstthe stileof the sash by the spring strip 15. H The strip 11 is held in position in the groove 12 by means of bayonet slots 16 which are formed at'intervals in the rear end of the strip 11 andinterlock with rivets 17 which are positioned at corresponding intervals across the groove 12. After the strip 11 has been shifted rearwardly in the groove and then downwardly into interlocked engagement with the rivets 17 it is held against upward movementrby means of a latch 18. The e present invention resides in the construction, arrangement and operation of the latch.

The latch 18 consists of a substantially flat and generally rectangular sheet metal slide plate 19 which is shiftable' laterally of the guide in a guideway formed by two rearwardly pressed loops 20 in the web 14 of the strip 10. The end of the slide 19 adjacent the groove 12 is reduced and formed into a nose 21, which nose projects through an aperture 22 in the inner side of the groove 12 into an aperture 23 in the strip 11 whenthe slide is shifted in that direction. The movement of the, slide in that direction is limited by engagement of shoulders 24 on the slide with the inner wall of the groove 12 at the sides of the aperture 22, and is limited in the opposite direction by engagement of the other end of the slide with the rearwardly extending port-ion 25 of the fixed side wall 13.

In order to maintain the slide in any po-' sition into which it is shifted, the slide is made of spring metal, and is slightly bowed,

as shown in Fig. 5, whereby to cause the end of the slide opposite the nose 21 to press resilientlyagainst the rear face of the Web 14, which" Web may be advantageously corru- V gated at that point to increase the resistance I of the slide to movement. The slide 19 may 7 be easily shifted into either its latched or its unlatehed positionby the employment 01 an ordinary screw" driver. -A'na'rroW notch 26 is formed in one s'ideof the slide, and a .relatively wide V-shaped notch 27 is formed 7 in the Web-'14 in diverging opposi'tion' 110- the notch 26. In order to sh'i'ftth'e slide, the end of the blade of a screwdriver, shown in dotted lines at 28 in Fig. 4, is inserted. into the composite socket. formed by the notches a V Q6 and 27, and is turned in one direction orv theother, employing the narrow end of the V-shaped notch'27as a fulcrum in effecting the turning movement. 1 j I claim: v v r V 20, 1;.
