' 1 claim. (icl. 2oz-fee) Y Figure 5 is a sectional view on line 5 5, Figr)This invention relates to window constructions in whlch a window sash has an opening and clos- 1ng movement, as a raising and lowering movement, and particularly to sash holders for hold-y ing the sash closed or in various open'positions,

frame.

Y It has for its objectY to provide an operating member or bar for the sash holders located at opand the assembly of the sash holders in the sash extending the greater part of the width of the sash and operable by the hand or hands used in lifting the sash at any pointthroughout the width of the sash, and so mounted as to be held from any movement, except a bodily movement laterally relative tothe lengthwise dimension of the bar. Y v It further has for its object an operating bar extending the greater part of the Awidtlrof` the sash or length of a rail, as the bottom rail of the sash, and arranged lin `iuxtaposition to, or in pinch-handle relation to, a stationary lift handle extending the greater part of the width of the sash or the greater part of the length of the bottom rail.

It further has for its object a particularly simple construction and arrangement o-f motion transmitting mechanism between the operating bar and locking members `or bolts of the sash holder mechanism, and the assembly thereof in the bottom rail of the sash.

It further has for its object the construction of transverse or bottom rail and the assembly of the sash holder mechanism' and operating bar therein and also the construction of the transverse or bottom rail embodying a ventilatory and operating member or bar extending the greater part of the length of the rail and located so as notto interfere With the ventilator or ventilator l passages.

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 inv all the views.

Figure l is a fragmentary elevation of a win' ure 4.

Figure 6 is an isometric view of the sash holder mechanism.

Figure 7 is a fragmentary elevation of a sash showing a different type of sash holder from ating bar common to both of said sash holder mechanisms extending the greater part of the width of the sash, preferably along the transverse rail of the sash, as the bottom rail on .the outside thereof in contradistinction to within the same, locking members carried by the sash and coacting with means on the Window frame for holding the sash closed'and at different elevations, the operating bar` having a movement in a direction` lateral relative to the length of the bar itself, that is practically a rectilinear movement, and motion transmitting means between the bar and the locking members. The operating bar is arranged in juxtaposition to, or in pinch-handle relation to, a lift handle which extends the greater part of the width of the sash or length of the bottom rail.l

The bottom rail is formed up of metal to'have a lengthwise channel extending the full length thereof and with the bottom of the channel on the outer side of the sash. The sash holder mechanism is located in the end portions of the channel, and -the intermediate portion of the channel is provided with a ventilator, the bottom of the channel being formed with the Ventilating openings. v

I' designates the window frame which confines a window openingj 2 designates the sash, which is capable of having a raising and lowering movement in the frame I, the window frame and the sash being formed with intertting sash guides. 'Ihe Stiles and rails of the sash are here shown as formed of metal and shaped to receive themargins of the glass pane 3l with a suitable. glazing strip orpacking 4 around. the margins of v the glass pane.

The window here illustrated is particularly def signed for vehicles, as buses, wherein the window,

lwhen raised, moves man vinclined or arcuate path or a sash having a movement as shown in my patent application Serial No. 74,334, led April 14, 1936.

As seen in Figure 5, the stiles of the sash 2 are formed with channels 5 which receive ribs 6 provided on the frame l and a suitable fibrous weather strip "l U-shaped in general form is 1ocated in the channel and embraces the rib and holds the sash and the frame out of metal-tolnetal running contact.

The window frame structure, in so far as this invention is concerned, may be of any suitable construction.

The bottom rail i l of the sash is metal and preferably extruded metal, and is formed with a channel l2 extending the full length thereof and opening through the inner side of the'rail, that is, the side toward the interior of the vehicle, with the bottom of the channel toward the outside of the vehicle. The bottom rail Il is also formed with a channel in its upper side to receive the margin of the glass pane and the mounting therefor and on its lower side with a channel for receiving a weather or buffer strip i3 for coacting with the sill lil of the window frame. The bottom rail is also formed with a stationary lift handle ifi extending the greater part ofthe Width of 'the sash or the length of the bottom rail, this lift handle projecting from the upper porti u of the bottom rail above the channel i2. lt is interrupted or formed with slots for the operating bar, as will be hereinafter described. The bottom of the channel i2 is Aforrl^..ed with ventilator openings lli and a ventilator box l'! is mounted in the intermediate portion of the channel opposite said openings, this box also having Ventile-ting openings in its bottom. A closure or slide l is mounted in the box, this having openings i9, movable into and out of register with the ventilator openings in 'the bottom of the box. The slide or closure it is provided with asuitablo handle 2li located in the channel.

The sash holder mechanism includes locking inen'ibers 2i shown in Figur-e Il as sliding bolts movable edgewise relatively to the sash beyond tho edges thereof and coasting with suitable means, as openings 22, in the window frame l, an operating bar 2? carried by the bottom rail and extending the greater part of the length thereof, this being herel shown as pivotally connested on the lower rail with the pivotal axis eccentric to the bar, and motion transmitting mechanism' for transferring the ino-vement o1" the bar to the members 2 l. The bar 23 is here shown as carried at the ends of the arms 25 which are pivotally connected at to the lower rail. These rocker arms have lever arms 2l extending into the ch nnel i2 for coaoting with the motion 51ans 'ting means located in the channel. The bar is thus held from tilting about any transverse between the ends thereof and held from all other movements, except an up and down, swingingmovement in a vertical direction.

The motion transmitting means between each of the operating bar 23 and each member ZZ l. consists of an angle or bell crank lever 28, one for each lever arm 2l, a slide 29 operated by each angle lever and connected to the corresponding member 2i through an endwisely movable rod Each lever arm 2l' extends at a right angle to the arms 3i of the angle lever 23 in order to engage and actuate the lever 28, when the operating bar 23 is actuated. The arms 25 of the operating bar 23 are mounted on studs 32 projecting from bosses 32a provided on blocks `or carriers 33 tting into the end portions of the channel l 2. The carriers 33 are secured to a filler block 34 in the channel, the parts being held assembled, as by screws 35. The ventilator box Il is located between the ller blocks 34 in the opposite end portions of the channel l2 and the bottom of the ventilator box Il is provided with lugs lla secured, as by screws Hb, to the channel locks. The operating bar 23 is here shown as located above the lift handle I5 in pinch-handle relation thereto, and the arms 25 extend through slots or interruptions 3l in the lift handle I5.

The operating bar 23 is preferably arranged above the lift handle, in order that the operator in raising the window may release the bar to release the bolts, when the window has reached the desired height, in order that, after the bar is operated, the sash raised by means of the lift handle, the operator may release the bar, and

. after the sash is lifted slightly, the bar may be released during continued lifting until the locking bolts are free to ratchet into openings 22 in the window frame. The bar and lift handle are located so as not to interfere With the operation of the ventilator.

The angle lever 28 is mounted in a carriage (iii fitted in each end portion of the channel i2. This carriage is formed up of sheet metal having one portion folded upon itself at 39 to provide a space in which the lever 28 is mounted. The lever is pivoted at dll to the double wall portion 3S by a pin or rivet 4l. This has a head 42 within the channel which serves as a spacer between the carriage and a cover plate 43 for the portion of the channel housing the bolt, and

motion transmitting mechanism. The carriage (it is secured in position by a rivet or fastening member t4 extending through the double wall portion Se and through the bottom of the channel l2. The carriage 3B slidably iits on the rivet 44 so that it is readily demountable when the cover plate i3 is removed. A screw 4G extends through the cover plate d3 and axially into the rivet 44 to hold the cover plate in position. The spacer 42 holds the carriage 38 from displacement axially of the rivet lill. The carriage 38 is also formed with an angular portion Sila having a passage through which the rod 3l) slides.

The slide 2li is formed up ofy sheet metal to slide in the end portion of the channel l2 and is pivoted at lill to the lever 28. It is provided with a lug or fork 5i working in a groove 52 in the rod 393 which is fixed to the member 2i. A retraoting spring Sli is interposed between the inner end of each member 2l and the angular portion 38a of the carriage 38. pinching of the bar 23 toward the lift handle t5, the members 2i will be retracted inwardly through the angle lever 28, slides 29 and rods til, and, upon the release of the bar 23, the springs 54 will re-act, so that the members 2l can enter holes 22 in thewindow frame when the members become alined therewith.

As seen in Figures '7 and 8, the locking members, instead of being sliding bolts shiftable in a direction edgewise of the sash, are rocking bolts or latches movable about a horizontal axis extending lengthwise of the bottom rail and coacting with a rack mounted on the window frame and facing the Stiles of the sash. In Figures 'T and 8, @il designates the rocking locking member or latch, this being mounted on a rock shaft El' mounted in a casing S2 at each end of the bottom rail its of the sash. The latch Sil coacts with a rack 55 carried by the window frame 65 and confronting the inner sides of the stiles lili Sil:

of the sash. B'I -is the operating bar, the arms 68 of which are mounted on and keyed to the inner ends of the rock shafts 6I, the bar 61 and arms 68 corresponding to the bar 23 and arms 25 (Figures 1 and 2). 69 is the pinch-handle on the lower rail, corresponding to the pinchhandle I 5 (Figures 1, 2 and 3). The operation of the bar BI and the latches 60 is against the action of returning springs 'I0 acting on the rock shafts 6I. Movement of the bar 6l about the axis of the rock shaft 6I rocks said shafts '6I to Withdraw the latches 60 from the racksl. .The shafts 6I constitute the motion transmitting means between the operating bar 61 and the latches 60. This sash holder mechanism is particularly designed for wide windows and owing to its construction and arrangement, the wide window sash can be readily raised and lowered by pressure applied atr any point throughout the rlength` of the lift handle I5, and the bar 23 or 61 may be operated throughout the length of the lift handle I5. Owing to the bottom rail construction, the lock mechanism, With the exception of theoperating bar and associated part, is located entirely within the narrow thicknessv of the metal and lock mechanism, so operable throughout practically the entire width of the sash, does not interfere with the Ventilator mechanism located within the bottom rail.

What I claim is:

A sash holding mechanism for a window sash including a transverse rail slidable in the Window frame, comprising a movable operating bar extending lengthwise of the rail the greater part of the Width of the sash and being shiftable bodily relative to the rail, the operating bar being pivoted at spaced apart points to the rail on an axis eccentric and parallel to the longitudinal axis of the bar, the bar being entirely outside of the rail, Where it is accessible throughout a substantial portion of the width of the sash for operating movement, locking members carried by the sash and coacting with the frame, said members having an operating movement in a direction -edgewise ofthe sash, and motion transmitting means for transmitting the pivotal movement of the bar to the locking members, the rail having a pinch-handle extending lengthwise of the bar and arranged in juxtaposition thereto, the transverse bar being located above the pinchhandle, and the pivotal axis thereof being located below the pinch-handle. y
