VALVE OPERATING AND LOGKIN G MEANS.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed December 26, 1916. Serial No. 138,925.

To all whom it may concern:

Be it known that I, THOMAS Bin-IAN, a citizen of the United States, residing at Aliquippa, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Valve Operating and Locking Means; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to the type of valves used in train pipes for connecting the air brake systems of the several cars, and the object is to provide improved looking and operating means for the valve which may be easily and inexpensively manufactured, yet which will be highly efficient and durable.

IVith the foregoing general object in view, the invention resides in certain novel fea tures of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which constitutes a part of this application and in which:

Figure l is a transverse section of the floor of a railway car showing the application of the invention;

Fig. 2 is an enlarged top plan view partly in section;

Fig. 3 is a side elevation of Fig. 2;

Fig. 4; is a vertical transverse section on the plane of the line M of Fig. 3;

Fig. 5 is a similar view showing the relation of parts when turning the valve from the position shown in Fig. 1 to its other position.

In the drawing above briefly described, the numeral 1 has reference to the floor of a railway car and 2 designates the pipe line for the air brakes. The line 2 is equipped with a horizontally elongated valve body 8 having in one end a seat in which a ver tically disposed valve plug t is mounted, a nut or the like 5 being provided on the lower end of said plug for holding it in operative position while its upper end extends above the body 3 and is formed with a vertical slot 6. A vertically swinging valve operating arm 7 is flattened at one end and received in the slot 6, said end being mounted on a pivot pin 8 which passes through the plug 4. as shown. The other end of the arm 7 is flattened horizonta y to form a head. 9

to which the inner ends of a pair of transverse valve operating rods 10 are connected for universal movement in any preferred manner. The intermediate portions of the rods 10 project loosely through openings 11 in hangers 12 which depend from the car while the outer ends of said rods are equipped with suitable handles 13.

Carried by the end of the valve body 3 remote from the plug 4, is a transverse channel-shaped guide 14 disposed on the upper side of said body, the vertically swinging arm 15 of a locking member 16 being pivoted at the center of said guide by a suitable pin or bolt 17 the free end of said arm having a transversely elongated loop 18 preferably of arcuate formation on its outer side as shown, said loop receiving loosely therein the valve operating arm 7.

By the construction described, the arm 7 when swung to either position for closing or opening the valve, carries with it the loop 18 and falls by gravity to the lower end thereof as shown clearly in Figs. 1 and 3. In this position, the arm is below the pivot 17 of the locking member 16 and thus the latter will effectively prevent vibration of the car from shifting said arm so as to reverse the position of the valve. In order to swing the arm in question from one position to another, it is necessary first to force downwardly on the outer end of one of the rods 10, the hanger 12 thereof then acting as a fulcrum so that the inner end of said rod raises and carries the arm to the upper end of the loop 18. A pull or push on the rod, as the case may be, will then simultaneously swing the arm 7 and member 16 to the reverse position as will be clear from Figs. 4 and 5. When this position is reached, the arm again drops to the lower end of the loop and is thus locked against accidental shifting.

From the foregoing, taken in connection with the accompanying drawing, it will be clear that although the invention is of extremely simple nature, it will be highly etficient and durable. For these reasons, the construction shown and described constitutes the preferred form of the device but it is to be understood that within the scope of the invention as claimed, numerous changes may be made without sacrificing the principal advantages. Also, it is to be observed that the use of the device need not be restricted to air lines of railway cars since it is equally applicable for the steam lines thereof and wherever such a valve may be required.

I claim:

1. The combination with a vertically disposed valve, of an arm extending therefrom in a substantially horizontal direction and connected therewith for vertical swinging, and a vertically swinging locking member having an elongated loop in which the aforesaid arm is loosely received, said loop eX- tending above and below the pivot of the locking member and the arm being adapted to drop by gravity into the lower end of said loop to prevent accidental shifting.

2. The combination with a vertically disposed valve member, of an operating arm extending in substantially a horizontal direction therefrom and connected therewith for vertical swinging, a locking member having a vertically elongated loop loosely receiving said arm therein, the latter being adapted to fall by gravity to the lower end of said loop, a horizontal pivot for said looking member to permit it to swing from one position to another when the arm is operated to turn the valve member, an operating rod loosely connected with said arm and extending laterally therefrom, and a guide through which the intermediate portion of said rod passes, said guide serving as a fulcrum for the rod to permit a downward thrust on the outer end thereof to shift its inner end upwardly to raise the arm to the upper end of the loop before swinging said arm from one position to the other.

3. The combination with a horizontally elongated valve body and a vertically disposed valve member at one end thereof, of an operating arm extending in substantially a horizontal direction from said valve memher and connected therewith for vertical swinging, a normally horizontal arm pivotally connected with the other end of said valve body for swinging transversely thereof, said arm having on its outer end a vertically elongated loop receiving the operating arm loosely, and operating means connected with said operating arm.

4. The combination with a horizontally elongated valve body and a vertically disposed valve member at one end thereof, of an operating arm extending in substantially a horizontal direction from said valve member and connected therewith for vertical swinging, a chaimel-shaped guide member carried by the upper side of said valve body at the end thereof remote from said valve member, a normally horizontal arm pivoted at one end within said guide at the center of the latter. the outer end of said last named arm having a vertically elongated loop receiving the aforesaid operating arm loosely therein, and operating means connected with said operatin arm.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

THOMAS BEHAN.
