view on the line 3-3, Figure 1.
Figure 4 is a fragmentary detail view in elevation showing on an enlarged scale the latch mechanism and piston.
Figure 5 is an edge view of the parts shown in Figure 3, partly broken away..
Figure 6 is Van enlarged detail sectional view of the sash lock and a portion of the piston.
It is a. .known fact that it is practically 5 impossible for passengers to open the windows of railroad cars and that in many instances it is necessary for the porter to use a force bar especially madev for this pur- OSG. p The object of my invention is to provide means which upon the operation of a push button the window sash will be pneumatically opened.
The reference numeral 1 designates a sash 3,"are mounted.
In the hollow wall of the structure I provide two cylinders 4 supported on the brackets 5, and further supported in vert1cal position by the brackets 6. The cylinders 4 are provided with piston rods 7 which project upwardly therefrom, through the window sill beyond the ends of the lower ra1l 8 of the sash 3 and are connected to the mechanism'of the latch 36, as hereinafter described. The cylinders are connected at the bottom by means of a pipe 9 having T union 10 from which a pipe 11 extends upwardly and is connected at its upper end to a control valve 12.
structure in which the window frame 2, and
450,129. This upward movement continues This valve 12 is ositioned, referably, in the hollow wall o the carI tructure) as shown in Figure 2, and has a three way opening, the pipe 11 being secured in the opening 13 thereof. The branch 14 of the valve 55 is closed at its outer end by a cap 15. The elbow 16 screws into the port 16a. At the inner end of the cap 15 is formed a conical like seat 17 on which one end of the spring 18 is seated. The inner end of the branch 60 14 is closed with aplug 19 having a-port 20 therethrough, vand the inner end of the branch 21 has a somewhat similar plug 23 at its inner end, the outer end of the branch 21 being closed by the plug 24 provided lwith 65 an opening in which the rod 25 .of the. push button 26 is slidably` mounted.V 'This rod 25 is' provided at its inner end with a` stem 26 which carries a valve plug 27 held thereto b Y means of the screw 28, said plug `seating in 7o the seat 9 formed at one end of the plug 19, and normally held toits lseat by the spring v18. The inner end of the rod 25 is provided with a valve plug 31 which is` adapted` to seat on the valve seat 32 of the plug 23. Pipe 33 is screwed to the elbow 16 at one end and to the air `supply pipe `34 at the other end. The valve 12 is also provided with an eX- haust port 35. When the push button 26 is pressed inward it closes the valve 31, opens the valve 27, whereby air from the supply pipe 34 passes through pipe 33 through port 16a into the valve 12, thence through pipes 11 and 9 into the cylinders 4 thereby raising the pistons and releasing the latch pushing the window up, as fully described in my application filed May 6, 1930, Serial No.
so long as the push button is depressed, or until the sash hascompleted its opening movement where it is held by its latch 36. When pressure on the push button is removed the parts assume the position shown in Figure 2 whereby the cylinders 4, pipes9 and 11 are open to the exhaust 35, inwhich lposition the sash is free to be lowered by hand on operating the latch 36. Itis, of course.'understood that the latch 36 will hold the sash to any desired open position.
-gThe pipel-l-is@infected to the usual eii'iergency"reservoir found on all railroad cars, or other suitable sources. The` amount of compressed air required in so slight that with the operation of all the Windows in the cr, on all cars in atrain equipped with this device, there is no likelihood of reducing the air pressure so as to cause applica tion of the brakes-on the car.
The latch mechanism is shown in detail in Figures 4, 5 and 6 in connection with the lifting piston or plunger 7. As shown, the piston rod 7 is provided at i-ts upper end with a transverse slot 37 into which the outer end of a plunger bolt 38 projects, said bolt being of the bell crank lever type, one of which functions as an operating handle 39. This lbolt is pivoted at 40'in a casing 41, which is provided with a recess 42, in which is mounted a rod 43 on which a coiled spring 44 is mounted, one end of the spring being seated on the supportl 45, While its other end is seated von the shoulder 46 of the latch 36. This latch 36 is adapted to be projected by the spring 44 beyond l/its casl ing 41 to engage a suitable keeper on the window frame which may be of any desired construction. The spring 44 maintains the latch 36 in its projected locking position normally, but when the handle 39 is operat ed the spring is compressed and the latch 36 withdrawn from engagement with the keeper 42 by reason of the fact that the handle passes through a slot 47 in the latch. In order'to accommodate the vertical movement of the outer end of the plunger bolt 38 the'slot 37 in the plunger is elongated, as shown. A suitable filler 48 is secured to `the bottom edge of the sash, through which the piston travels. The piston, push rod or plunger rod 7 is slidably mounted in the casing or cylinder 49. This rod may be provided, or not, with a piston head.
The design and construction of the entire mechanism is such that it will requireno maintenance, or lubrication, from shopping i to shopping of the car. f'
' The device provides, in commercial equipment, for tWo one inch cylinders 4 for each sash, one on each side. When thewindows are double sashed four cylinders'would be required. My tests in railroad cars, however, have indicated ythat one cylinder to each sash may be adequate, in Whichevent only one cylinder 4 would be required to raise each sash.
-What I claim is:
In a Window operatingdevice, a Window` ,frame structure having an opening therein and a compartment beneath the same, a sash slidably mounted in the openin locking means at opposite sides of the rame and sash for holding said sash in adjusted position in said frame, and fluid operating mechanism for simultaneously releasing said locking means and raising vthe sash, said means comprising cylinders in the said compartment, pistons in said cylinders operatively coupled respectively to the vlocking means at the opposite side of the sash for releasing said locking means and raising the sash on an upward movement of the pistons in the cylinders, a valve movable in opposite directions for fluid supply and exhaust actions, a pipe connecting the vlower ends/0I
