11 Claims.

This invention relates to window constructions, particularly for railway cars, motor busses, and the like, and has for its object, a particularly simple and adjustable means for applying a predetermined pressure to the window stop for holding the sash tight against rattling without binding the sash in its guide.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary elevation of a window construction embodying this invention.

Figure 2 is an enlarged, sectional view on line 2-2, Figure 1.

Figure 3 is a fragmentary inner face view of one of the stops.

Figure 4 is a detail view of the screw threaded socket for receiving the adjusting screws for the adjustable stop.

Figure 5 is a fragmentary view of one of the outer stops.

In window constructions, such as are used in motor busses and the like, the window sashes must be held sufficiently tight to prevent rattling, and at the same time be capable of being raised and lowered without binding.

At the outset, window stops can be arranged so as to so hold the sashes, but during use, because of dust and the like finding its way into the sash guide and there being no place for the dust to work out, the sashes become difficult to raise and lower.

Ihe principal feature of this invention is means by which this condition can berelieved quickly by adjusting one of the window stops, usually the inner stop.

1 designates the usual upright frame members or posts of a window frame.

2 and 3 designate respectively outer and inner stops which form a guide for the stiles e of the sash 5, one of these steps, usually the inner stop,

, being spring pressed with a predetermined spring pressure againt the sash.

One feature of the invention is the adjusting of this spring pressure, or adjusting the thrust or pressure of the adjustable or inner stop against the sash, so that the sash will work without rattling and without binding.

The outer stop 2 which, in this embodiment of my invention, is not adjustable, may be of any suitable form, size and construction, it being here shown as right angular in cross section with one flange forming the outer stop, and the other flange '1 seating against the post.

The adjustable inner stop 3 is channel shaped in cross section with the bottom 8 of the channel lapping the inner face of the frame member or post 1, that is, the face toward the interior of the vehicle, with the side flanges of the channel spaced apartfrom the side faces of the frame member or post 1, and with inturned flanges 9 at the entrance of the channel formation, which flanges thrust against the stiles 4 of the sashes.

The stop 3 is thus double construction and angular in cross section, open at one side, and with the open side toward the frame member or post 1. The stop 3 is secured to the post or frame member 1 so as to be yieldingly pressed against the sash or sashes by springs, and the tension of the springs adjusted to adjust the thrust or grip of the stop 3 on the sash or sashes.

10 designates springs located within the stop 3 on opposite sides of the post or frame member 1 and interposed between the flanges 9 and the opposite ends of a spring abutment or plate 11 extending transversely of the outer face of the frame member or post 1 under and spaced from the bottom flange 8 of the stop 3. The abutment is here shown as slidably mounted'upon studs 12 secured at like ends to the bottom 8 of the channel formation, and at their other ends extend into the flanges 9, and the springs 10 encircle said studs.

The means for securing the abutment to the frame member or pillar 1 and adjusting it to adjust the tension of the springs 10 comprises a member as a screw 14 extending throughthe bottom 8 of the channel shaped stop 3 through the abutment and threading into the frame member or post 1, the screw having its head 15 thrusting against the outer face of the abutment 11, so that as the screw is tightened, the abutment will be moved inwardly toward the frame member or post 1, thus compressing the springs so that they act with greater force against the flanges 9 and thus thrust the stop 3, or the flanges 9 thereof with greater force against the sash or sashes. Loosening of the screw lessens the thrust or force of the springs against the flanges 9. Owing to the mounting of the abutment 11 with the screw located between the ends of the abutment and between the springs, it has a rocking or equalizing action against the upper ends of .thesprings 10. For the end windows, where the pillar or frame member 1 does not separate two window constructions, any suitable member may be substituted for f one of the sash stiles for the stops to thrust against.

The screws 14 preferably thread into a longitudinally split threaded socket provided in the frame member or post 1. 16 designates the socket split longitudinally at 17, and having a face plate 18 at its outer end overlying the face of the frame member or post 1 and secured thereto in any suitable manner, as by screws 19. The socket is first threaded and then split, and then the sections thereof compressed inwardly so that when the screw is turned in the socket, the sections of the socket grip the screw and hold it from unintentional turning. There may be one or more abutments 11 and companion springs 10, and adjusting screws 14 spaced along the outer stop, and there are usually three of sun abutments near the upper and lower ends and midway between the ends of the stop.

The heads of the screws 14 are preferably formed so that a special tool, wrench, or screw driver, is required to operate them, whereby the screws can be adjusted only by authorized persons. As shown, the heads of the screws are formed with spaced holes 29 requiring a tool with similarly spaced prongs.

The inturned flanges 9 of the stop are preferably provided with wear strips 21 for engaging the sashes, which strips are secured thereto in any suitable manner, as by rivets 22. The stop 3 is usually formed of steel and finished to represent wood, or in any other manner, and the wear strips are brass to coact with sheet metal hollow stiles of the sashes. The angular stops 2 are also preferably brass.

25 is a facing or trim strip for the outer side of each post 1, these being in the general form of a channel embracing the post with the bottom of the channel the post, and the side flan es 28 lapping the sash sides of the post and provided with angular 27 lapping the flanges 28 of the angular outer stop 2. v The facing strip 25 is permanently secured to the post as by screws 29, and is not intended to be removed. It is usually steel enamelled, painted, or otherwise finished.

Usually, the stops 2 are secured to the post 1 rather than to the facing strip 25, and aresecured to the post, as by screws 30, extending through the flange 7 of the stop 2, which flange '7 seats against the post.

The flanges '7 of each of the stops 2 are provided with holes 32 for receiving the bolt of a sash holder or lock 33, which. bolt moves through the edges of the sashes, the post 1 being provided with bores 34 alined with the holes. 32 for receiving the ends of the bolts.

The sash locks or holders 33 may be of any suitable construction, and there is usually a sash lock or holder at the lower corners of each sash.

Each includes a finger lever 36 which is connected, through any well known mechanism, to the bolt. r

In operation, when the sash is first inserted, the inner stop 3 is adjusted by turning the screws 14. After the sash has been in use and the sash guide fills more or less with dust, or other material, tending to cause it to bind with such initial adjustment, the screws 14 can be unscrewed slightly, as a quarter or half turn, thus relieving the tightness.
