Serial No. 239,584.

This invention relates to improvements in sashand frame constructions and morepan ticularly to a construction whicheliminates the necessity of'usin'g latches for securing the sash in adjusted position and tofa construcadvantageous features and refinements. j L s lhile the oonstruetionaboutfto be disclosed is adaptable -iior use in various diiferent ways it finds particular utility in connection with buses and the like. In motor vehicles-such' as buses `difficulty is* eXperie'nced in Afitting the sashes to the frames because of the variances in the distance between the frame members.

If a standard or'uniform size sash-isem'ployed as is the custom it is lfound that in some instances the sash llits the rame'member -too tightly and in other instancestoo loosely so that on the whole thefitting of sashesft'o the iframes is 5 "difficult, 'expensive and otherwise unsatisfactory. Furthermore because ofthe weaving of theirame of the vehicle inuse and by reason offotherdistortion ofthe sash frames, di'iculty is frequently eX'peiienced'in vraising andlowerihgthe sash. Many of the heretofore known forms `of sash havealso been found -to be {objectionablebecase the construction necessitated'the use "Oflatches or the like to hold `the sash-infadj'u'sted position. v i t is therefore one 'of theprimary objects of this invention topiovide'a latchless sash and frame construction which may-'be read-ily assembled irrespective of variations inthe distance between the jframe membersV or the dimensions of the "sash `and l'which' 5may be 'readily raised and lowered withoutliability 'of the same binding. VIn'a`ccomplishing this I provide aframe, the side members oi which have their inner walls for portions thereof transversely oppositely inclinedv thns 4providing ay tapering opening o'rf recei-vmgthel Resilient means is associated with Ytlnefsa'sh' normally urg'ing'the sash transversely ot the l frame members toward the converging'edges of the inclined walls. Notched members are associated with the iframe' members y'adjacent' the convergingedgesoff lthe inclined walls, the sash'being urged intol engagementwith these notched yrr'iembers bythe resilient means wherein: Y VFigurel is an elevational view "of'a `sash Vraised or lowered and when releasedthe resilient means again urges thesashl transversely toward the converging edges of the inclined side walls and into intimateengagement with these side walls and also into engagement with the notched members. By reason oi the tapering character oi the frame Vopening sashes of Vvarying width may be accurately iitted within the iramefand 'variance in the distance between the frame members is also of no consequence.

The several objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection Awith the accompanying drawings andv frame constructed inV accordance `with this invention.

Figure 2 is a vertical sectional view Vtaken substantially on the plane indicated by line 2-r-2 in Figure 1.

Figure 3 is'an enlargeddetail sectional view' taken substantially on the'plane indiv lcated'by line 3-3 in Figure 1.

V Figure 4 is a similar sectionalview taken substantially on the plane indicated by line 4 4 in Figure 1, and y Figure `is a detail sectionalview showing :1n-application of the invention to a `metal bus construction.

Referring now to the drawings and more especially to Figures 1 to4 inclusive it will ybe f noted that there is illustrated a frame VIVwhich consists essentially of a pair of spaced side members 10,- a sill-rl-lrand aheader 12. A'sash is slidably mountedV in the frame and consists ofa top member 13a bottom member V14 and av pair otside members 15.

The members 13, 14 and 15 of which the sash is compos'ed'may beoi any desired form or construc- Ytion lbut are ormed'with channels or means providing a channel by means of which the glass 16 is secured in place. rlhe lower sash member lll is formed with a channel or recess 17 in which a tubular compressible weatherstrip 18 is secured which in the closed position of the sash is adapted to engage the sill 1l to weatherproof the sash at the lower edge thereof.

The upper sash member 13 is formed with return-bent portions or tongues 19 engaging in grooves or recesses in a weatherstrip 2O which weather-strip is formed with a laterally projecting lip or extension 21 adapted for engagement with a surface or wall formed interiorly of the headerl 12. This surface 22 is inclined with respect to the path of travel of the sash and as the sash approaches its closed position lip 21 engages surface and thus weatherproofs the sash at the upper edge thereof.

1n the construction shown in Figures l to 4 the pillars or side frame members l0 are illustrated as of wooden construction, and in such cases it has been found to be desirable to associate or secure to the inner face of each pillar 10 a plate or face member 23 which in effect becomes a paie of *he side frame members. This plate member is bent to provide a transversely inclined portion 24 and a laterally extending llange portion 25 constituting aportion of the sash guide. The other edge of each plate member is bent to provide a member 2G which is notched longitudinally thereof as indicated at 27. lillhile the notched member 2G is here shown as formed integrally with plate member 23 and while this is a convenient form of construction nevertheless these notched members may be constructed separately and secured to the side frame members in any desired manner.

'lhe side sash members l5 are each formed with a portion or surface 28 adapted for engagement with the inclined walls 2d of the pillars or frame members. As shown this portion of the sash members is curved or arcuate in cross section and from an examination of Figure l it will be noted that the sash members l5 are recessed to accommodate and receive weatherstrips 29. Y

Means is provided for resilient-ly urging' the sash transversely of the frame into engagement with the inclined walls of the latter and toward the converging edges thereof or in other words toward the narrower portion of the frame. 'Vhile any desiredform of resilient means may be employed there is illustrated herein coil springs 30 located within the side sash members l5 which act upon plungers 3l slidablymounted in the sash members. These plungers 31.en gage the flange member 25 and thus urge the sash member transversely of the frame and into .engagement with the inclined walls thereof. rlfhe side sash members may each be formed with a laterally extending lip or flange 32 which acts as a cover flange and cooperates with the flanges 25 carried by the frame members to concealthe plungers 3l and to protect the same.

rlhe lower sash member is provided with a tongue or projection 33 which may be formed separately and secured thereto or may illustrated herein be formed of an integral part of the lower sash member lll. rlliis tongue or lip 33 is 'adapted for engagement with the notched members 2G for securing the sash in any of its adjusted positions.

It will be obvious that the sash may be easily raised and lowered by gripping handle members 34 and moving the sash transversely against the action of the spring pressed plungers 31 toward the diverging edges of the inclined side walls of the frame or in other words between those portions of the side frame which are spaced wider apart. This will give ample clearance between the sash and frame to permit the sash to be readily raised or lowered and if the sash has been raised when the same is released the spring pressed members will urge the same transversely of the frame and cause the lip 33 to engage in the adjacent pair of notches 27. lWhen the sash is in its lowermost or closed position the lip 33 extends into the recess formed by cutting away the lower edge of the notched members as indicated at 35.

In Figure 5 there is illustrated an adaptation of this invention to all metal construction wherein a pillar constituting one of the frame members is indicated by the reference character 36 and as shown consists of a member substantially T-shaped in cross section. Brackets or anchor `members 37 are secured to each pillar 36 at spaced intervals throughout its length and a member indicated generally by the reference character 38 is shown as entirely enclosing the pillar 36 and anchor 37. This member may be conveniently formed of sheet metal substantially in inverted U-shape in cross section. The base of the U is formed with shouldered portions 39 adapted for snap engagement with Athe head of the T-shaped pillar member. The member 38 is formed with laterally extending flanges Ll0 constituting a portion of the sash guide and retainer plates 41 are secured to the anchor members 37 the ends 42 of these members constituting flanges completing the guides for receiving the sash. That portion of the member 38 adjacent each flange 40 is shaped to provide an inclined wall 453 for cooperation with the sash as in the previously described form of` construction.

With a sash and vframe constructed in accordance with the present invention it will be obvious that sashes may be more readily fitted to the frames without regard to variances in the distance between frame members or in width of the sash. The tapering side walls of the frame and the spring pressed means for urging the, sash into enga-gement therewith will under ordinary conditions provide sutlicient latitude to permit of a satisfactory fit between the sash and frame despite any ordinary variances in dimensions. Furthermore by reason of the fact that the sash may be moved laterally toward the diverging edges of the inclined side walls of the frame a sutlicient clearance between the sash and trame is always possible to thus enable the sash to be readily raised and lowered. The spring pressed means normally urging the sash into engagement with the walls of the frame will compensate for wear between the parts and prevent rattling. -Furthermore with the herein described construction thev sash may be held in its adjusted position without necessitating the use of a complicated latch mechanism.

Obvious changes Vin the details of construction and rearrangement of parts may suggest themselves to those skilled in this art and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.
