ject' of this invention, the leadingaims and .objects being, first, in sashes having spr1ng-' pressed shoes cooperating with guides and having co-acting V-shaped or inclined surfaces,'to provide effective and simple means to limit the, transverse movement of the sash and shoes, it being obvious that in someconstructions of this kind, if sufiicient pressure is brought against the window and its sash, the shoes, owing to the cooperating inclined surfaces, may be pressed in sufficient] to free the window from its guides; secon the provision of new and useful forms and styles of spring, sheet-metal glazing strips; third, the employment of simple and economical means for finishing the corner portions of the window-sashes; and, fourth, the

mounting of the locks on the sliding shoes rather than on the sashes themselves. These, with other features of novelty and improvement, will be made clear to those skilled in this art from a consideration of the following detailed description, which should be taken in connection with the accompanying drawings forming a part of this specification, and throng out the various views of i I which like reference characters refer to the same parts.

In these drawin tary face view 0 a window composed of two sashes, such window being especially suitable for use in railway or street cars, though not necessarily restricted to such em-' ployment; Fig. 2 is a vertical section on line 2-2 of Fig. 1; Fig. 3 is a horizontal section through one of the window-sashes and one of the sash-guides; Fig. 4 is a similar View illustrating a modified construction and showing the application of the lock to the springpressed shoe mounted on the sash; Fig. 5 is a similar view showing a modified construction in the shoe, sash and glazing strip Fig. 6 is a horizontal section on line 6--6 of Fig. 1; Figs. 7, 8. B and 10 illustrate a variety of embodiments of this invention, all

, Figure 1 is a fragmens of such views indicating horizontal sections;

Fig. 11 illustrates a section through a corner portion of one of the window-sashes; Fig. 12 is a perspective view of a portion of the construction shown in Fig. 11; and Fig. 13 is a partial plan view and partial section of the elements shown in Fi 11.

Referring to the drawings, it wifi be apparent that I have indicated two windowsashes 20 and 21,.supplied with sheet- metal sashes 22 and 23, panes of glass 24 and 25,

,and suitable glazing strips described. hereinafter.

Referring to Fig. 3, it will be obvious that the side window-casing or upright post has fixed thereto by screws 26, 26, a bent sheetmetal plate 27 formed to provide a recess 28 for the guidance of a blind, curtain or shutter, and a pair of V-shaped sash-guides 29 and 30, the metal at the apexes of the We referably being bent inwardly to su ply ongitudinal grooves or recesses 31. T e window-sash characterized 22 is of-hollow sheet-metal, box-like construction having a flat outer face and an undercut head or rib 32 on its inner face, which is provided for the attachment of the glazing strip described hereinafter.- Fitted over the side members of the sash and capable of telescoping therewith, I provide a sheet-metal guiding-shoe 33 having a longitudinal recess 34.- on its outer face adapted to conform to and receive the correwondingly shaped guiding-ribs 30 of the metal strip 27. Along the center of each of such recesses is an outwardly-extended rib 35 adapted to fit in and slightly narrower than the longitudinal grooves or sockets 31. In order to press such shoes outwardly into firm engagement with their guides, whereby to exclude the dirt and the outer air, I set in apertures of the sash 22 any suitable number of sheet-metal pockets or sockets 36, and place in the same coiled expansion springs 37, which at their outer ends contact with and bear against the inner face of the guiding shoe.

Under normal conditions, the ll-shaped or inclined surfaces'of the spring-pressed shoe and guide bear against one another andre tam thewmdow-sash securely 1n place. If, however, any great transverse pressure is exer-ted on the window-sash from either-side,

owing to the wedge action between the shoe and guide, there is a considerable tendency to push the shoe inwardly against or in opposition to the action of its outwardly-pressing spring so as to free the shoe from the guide and detach the window-sash from the casing. This is prevented, however, by the tongue or rib 35 engaging one or the other of the sides of the groove or trough 31 upon a slight transverse movement of the shoe, such engagement creating sutlicient friction between the parts to prevent the inward movement of the shoe relative to the shaft by the wedge action referred to above. 'Under ordinarycircumstances, the rib 35 does not and is not intended to contact with either side of the longitudinal groove 31, but is intended and adapted to strike one or the other of such surfaces upon attempted transverse displacement of the window-sash, and

under such circumstances these parts act as a stop to limit such movement of the window. Each window-sash around its entire inner surface is supplied with a rib or bead 32, and over the same I snap sheet-metal glazing-strip sections 38 (Fig. 6), between the inwardly-extended portions 39 of which is adapted to be received the rubber, felt or other strips 40 fitted over the edges of the glass. The glazing strips38 are so formed as to engage around-the shoulders or neck of the bead 32, but between such shoulders the glazing strip is bowed inwardly at 41 away from the bead 32 to give more spring to the strip and to facilitate its application to the bead, such bowed part of the strip also acting as a cushion for the rubber strips 40, or the glass proper when the latter are not employed, direct contact between these parts being maintained, as is clearly shown in Fig. 6. These glazing strips whensnapped upon or fitted over their supporting undercut beads do not-reach the corners of the sash, as is clearly indicated at 42 in Fig. l, where my improved corner pieces are omitted. Each corner of the sash is provided with two corner plates 43, one on each side of the sash, such plates overlapping the ends of the glazing strips, and being fastened together by a screw 44 which engages the internal threads of a socket 45 fastened in any suitable manner to the inner surface of the companion plate 43 on the other side of the window, such socket or sleeve being out of contact with the bead 32, the glazing strips and the pane of glass proper, which is cut off diagonally at its corners for thispurpose, as at 46, Fig. 1. By this means I am able to neatly finish the corners of the window-sash by lates of the general style and shape shown in Figs. 1 and 6, which plates overlie the end portions of the glazing strips and whose securing means in no way conflict .or interfere with the other parts of the construction.

The top and bottom members of the lower window-sash are, of course, not provided with the spring-pressed sliding shoes, but

have the general box-like construction shown in Fig. 2, and are equipped on their inner surfaces with the beads for holding in place the glazing strips. The bottom member of the sash is of beveled or inclined formation at 47 so as to fit the window ledge, as is customary and usual in constructions of this character. The sash of the upper window sectionis clearly indicated in Fig. 2, and does not require further description.

In Fig. 4, I have indicated a horizontal section through a single window-sash, and have shown several changes over the construction described above. In this instance, the sheet-metal sash 48 is made of a single strip of metal bent to shape, the two ends thereof 49 and 50' being overlapped and riveted, or otherwise secured together, on the outer face of the sash. The inner face of the sash is formed so as to have an undercut groove 51 intended to receive and hold in place the glazing strip, also made of sheet-metal. This strip, characterized as a whole 52, has the two inwardly-extended double portions 53 adapted to engage the opposite sides of the glass 54, the glazing strip between such parts having two inwardly-projected loops or bows 55 and 56 and an intermediate spring section or bow 57 adapted to engage the edge of the glass and act as a cushion therefor. The edges of such glazing strip are bent at 58 and 59 to hook or spring into the undercut groove 51, being shaped to conform to the parts of the sash overhanging such groove. Owing to this snug engagement of these ends, which may be readily pressed toward one another for their insertion in the saslrgroove, I provide an effective means for excluding dirt, moisture and the outer air. The sliding shoe 60 telescoping with the sash member 48 is substantially like that of Fig. 3, and'needs no detailed description here, it being sufiicient to state that the shoe is pressed outwardly by a coiled spring 61 inserted between the inner surface of the same and the adjacent outer surface of the sash. To this shoe I secure, by means of screws, rivets or the like, 62, a casing 63 containing a sliding lock-bolt (34, which is adapted to be projected intoone or more recesses or cavities 65 provided in the sheet-metal plate 66 securedto the upright post of the window-casing and shaped to form a suitable guide for the sash shoe, as in the previous instance. By mounting this locking bolt on the shoe rather than on the sash, as has been customary, the lock is maintained at all times in the same and proper relation with the metallic strip 66 with which it cooperates, so that an effective looking or socuring of the window at the proper height can be attained at all times.

In Fig. 5, a somewhat different construction isshown, the hollow sheet-metal sash member 67 having its ends overlapped at 68, as in the previous instance, the sheet metal of the sash being so formed or bent back upon itself to provide two longitudinal channels 69, 69, which are intended to accommodate the longitudinal ribs 7 0 of the spring-pressed shoe 71, the outer face of which is much like those of Figs. .1 and 3, while the end portions 72 of the strip constituting the same are bent back so as to overlap the outer faces of the sash member 67. In order to press this shoe outwardly, I interpose between its inner surface and the glazing-strip head 73 of the sash, a coiled expansion spring 7 4, the function of which is obvious. In this instance the bolt 75 and its casing 76 are riveted or otherwise fastened to one of the end parts 72 of the sheet-metal strip of which the shoe is formed up. In order to protect this shoe from the elements and to assist also as "a stop member preventing outward displacement of the window-sash, the metal sheet 77 fastened to the window casing and bent to form the sash-guide is also shaped to supply the abrupt shoulder 78 overlapping partially the outer face of the shoe.

Still another embodiment of this invention isindicated in Fig. 7, and in this case the window-sash 79 is made of sheet-metal and. is of substantially u form', having, as

in the, previous instance, an inner head or rib 80 for the attachment of the glazing strip, which in this view is omitted. In this particular construction, the guiding shoe is pressed outwardl such sash, a's-.is clearly indicated, and being formed of a single stri of metal bent as is illustrated to. form a triangular shapedhollow body 82, one end portion 83.'of the metal being bent directly outwardly parallel to the plane of the sash and forming a fiat surface with which one of the legs of the u-shaped sash cooperates, the other end having shdin'g engagement with one side ofthe triangular shoe body 82. The sheet of metal 84 is attached in any approved manner to the window-casing, and is so bent as to provide a guiding groove 85 containing a rib 86, one wall 87 of which is inclined to the plane of the window-sash, while the other wall 88 is substantially parallel to said plane. As is shown, the inclined and straight surfaces of the springpressed sliding shoe cooperate with the corresponding surfaces of this rib. Upon attempted outward transverse shifting of the sash, the same is brought into engagement by ,a bow spring 81. housed in the sas the shoe fitting within rib, it may be replaced by a correspondingly-shaped groove, and in Fig. 8, I have shown such a construction, in which the plate 89 is bent to provide such a groove or cavity 90 having at its bottom a depression or supplemental groove 91 with straight sides. In this particular instance, the sash and spring shoe each partially overlaps the other, .the sash 92 being of general U-shape and having the usual head 93, and in addition the ends of the legs of this sash are bent inwardly at 9% to form a neat finish and strengthen this portion of the construction. The shoe, which is pressed outwardly by-the leaf spring 95, is of hollow shape and has inclined flaring surfaces 96 and 97 cooperating with the corresponding sides of the guiding groove 90, and along its outer edge the shoe has a rectangular rib 98 fitted in the supplemental groove91, but of somewhat less thickness, so that its sides do not normally contact with the walls of this groove, but are permitted to contact therewith and, form a stop when the shoe is shifted transversely. One part of the sheetmetal blank from which this shoe is formed, characterized 99, is disposed outside of. the

sash member 92, and has secured thereto a lock-casing-100 and a lock-bolt 101, the function and purpose of which will be understood by all those skilled in this art.

In another construction, illustrated in detail in Fig. 9, the plate. Si is formed substantially as in the construction of Fig. '7, providing a guiding groove 85 having therein a guiding rib 86 with inclined and straight surfaces 87 and 88, respectively.

The sheet-metal sash-member 102 is much of the same form as that of Fig. 7, and has witliinit a bow spring 103 pressing outwardly a guiding shoe 10 having a triangular hollow body and an extension 105 of U-shape, andreceiving in its groove one leg of vthe sash 102, thereby assisting in the proper guiding of the shoe in its reciprocations. The U-shaped extension 105 fits in the rectangular portion of the gro n-e 85 and is'adapted to be brought into contact with either side of the same upon attempted lateral displacement of the sash, as has been described in connection with the other consti'uctions. The Jundercnt. or headed bead 106 of tliis sash has a face adjacent to the glass of V-shape, the glazing strip of spring sheet-metal 107 being adapted to be sprung over such head, as in the previous instance, but the glazing strip being inwardly bowed at 108 on a curve does not follow the contour of the face of the bead, thereby allowing considerable give or spring for the ready application of' the strip to the bead.

conform substantially to the spring-pressed shoe 112 of general U-shape, which overlaps the sash member and has an inclined wall 113 co-acting with the correspondinglyshaped portion 114 in the guiding groove 115 of the windowrgasing, the opposite wall 116 of such. groove being substantially parallel to the window-sash. A plunger 117 is riveted or otherwise secured to the inner face of the shoe and projects through alined holes in the sheet metal forming the sash 109 and a filler block 118 fitted inside of said sash.- This plunger, as will be readily understood, assists in the proper guiding of the shoe, which is pressed outwardly into engagement with the guiding surfaces by a coiled expansion spring 119 encircling such plunger. To one leg of this shoe, the lockbolt 120 is secured for the well-known purpose of holding the window in adjusted position. The shoe described is slightly narrower than the guiding groove in which it adapted to be sprung over the same, as has.

been fully described above. This glazing strip, however, has a ll-shaped part 125 disposed inwardly away from the bead I23 and bearing against the rubber or felt strip 126. By this construction, the part 125 acts as a cushion for the glass and its strip, and 'gives the glazing strip added resiliency for application to its retaining bead.

In Figs. 11, 12 and 13, the construction of a window-sash of this kind is indicated, especially at one of the cross sash portions of the window. The vertical sash section 127 has on its inner face the glazing strip or head 128, while the horizontal sash section 129 is provided with a similar strip 130. The guiding shoe 131, of any suitable con struction, fits over and telescopes with the sash section 127 and the end portion of the horizontal sash-section 129, and is springpressed outwardly by a coiled expansion spring 132 fixed to the top end of the shoe,

such spring hearing at one end against the end of the casing and at the other end against a shaft or rod 134: which projects into the casing through a hole in its end.

The free end of such rod isheld in any suitable manner at 135 to the horizontal 6Q sash-section. By the employment of a conaeeaaai struction of this kind a simple and efiective means is provided for yieldingly forcing outwardly the guiding shoe, an efiective and secure connection-of the same with the sashbeing maintained by means of the casing or housing 133. In this particular instance, the outer end of the shaft 134 is held in place by a screw 135 passed through the sash, such screw passing inwardly of the casing through an elongated slot 136" therein.

The construction illustrated in Fig. 13 is similar to that of Figs. 11 and 12, with the addition that the shoe has the central stop rib 137, the object and purpose of which" has been clearly indicated above.

Although I have set-forth with some considerable degree of particularity a number of embodiments of this invention, 1 wish to have it understood, however, that the invention is not limited to these particular structures, since it is capable of many other embodiments not herein mentioned, all of which will fall within the scope of the ap pended claims.
