SWIVEL CURTAIN HOOK.

Application filed March 11, 1927.

In train makeups adjacent coaches usually have the vestibules connected by means of collapsible diaphragms which provide a passageway between the connected coaches or cars. To protect passengers or people passing through said passageway, curtains are usually provided covering the inner vertical walls of the diaphragm, the said curtains being usually of the roller type mounted on one of the railway car vestibule face plates while the free end of the curtain is provided with a handle which is usually engaged on a rigid hook mounted on the vestibule face plate of the second car. This arr qement has been particularly unsatisfactory in view of the fact that it very often happens on a single long trip that the friction action between the handle and the rigid hook completely wears out both the handle and said hook making it necessary to continually replace the same. This dii'liculty is not only expensive but is a continual source of annoyance.

To obviate the above conditions, this in vention has been developed to provide an improved swivel hook for use on the vestibule face plate of a railway car to permit the handle of the vestibule curtain to removably engage therewith so that friction between the curtain handle and the hook is substantially reduced to a minimum due to the fact that the movement of the handle by the curtain is compensated for by the swivel ac tion of said. hook.

it is an object of this invention to provide a railway car vestibule with a swiveled hook mechanism adapted to removably receive the handle of a vestibule curtain permitting movement of said handle without causing undue wear of the handle or the hook on which it is engaged.

It is an important object of this invention to provide a railway car vestibule curtain hook of a swivel type adapted to permit the handle of a vestibule curtain to be engaged thereon permitting movement of the curtain and handle without causing any sliding fric' tion action between the handle and the hook due to the pivotal mounting of the hook which compensates for the up and down movements of the curtain handle so that the life or use Serial No. 174,649.

of the handle and its respective supporting hook are materially prolonged.

Other and further important objects of this invention will be apparent from the disclosures in the drawings and specification.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a front elevation of a railway car vestibule curtain handle engaged with an improved retaining hook embodying the principles of this invention.

Figure 2 is a transverse section of the handle and hook taken on line Il-JI of Figure 1.

As shown on the drawings:

The reference numeral 1 indicates a portion of a railway car vestibule curtain, the supporting roller of which is adapted to be mounted in a vertical position upon the vestibule face plate of a railway car. One margin of the vestibule curtain 1 is provided with a hem 2 in which a curtain pole or rod 3 is engaged. Positioned over the curtain hem 2 and around the curtain rod 3 are a pair of clamping brackets 1 having integral exten sions or handle arms 5. The handle arms are connected by means of a handle bar or rod 6. The

handle members

4, 5 and 6 are connected with curtain by means of retaining bolts 7 or other suitable means and alford a vestibule curtain handle whereby the curtain may be extended from the vestibule face plate of one car over the diaphragm for removable con nection with an improved retaining hook or holder 8, the shank or stem 9 which is pivotally mounted on a stud or pin 10 which is internally threaded and is riveted or otherwise secured to a mounting plate 11 secured by means of screws 12 or other retaining means to the vestibule face plate of the second car. Removably threaded in the stud sleeve 10 is aretaining screw 13 which serves to prevent the shank 9 of the hook member from becoming disengaged from the stud 10.

With the vestibule curtain supported on the face plate of one car and a swiveled hook mounted on the face plate of an adjacent car, the curtain may be extended to reach from one car to the other by means of the handle 6 with said curtain when extended serving to cover one of the inner side faces of the vestibule diaphragm to prevent persons passing from one car to the other from coming into direct contact with the collapsible diaphragn'i. To hold the said curtain in position the handle 6 is merely engaged over the swivel hook 8. This combination obviates frictional wear on the handle 6 and on' the hook for the reason that the upward and downward shifting movements of the handle and curtain is permitted to take place due to the swiveled or pivotal mounting of the hook member on the plate 11. It will also be noted that with the swivel hook arrangement there is substantially no relative sliding movement between the handle 6 and th'chook 8 thereby relieving said parts of undue: wear which usually takes place between a vestibule cur tain handle and a hook when a hook of. the stationary type is employed.

In the present invention the combination presented aii'or-ds an improvement in the art Off railway car vestibule curtain handles and their supports whereby the life or use of the handles and swivel hooks are prolonged indefinitely thereby obviating the necessity of replacing handles and hooks which under the old arrangement must be repeatedly done.

I am aware that many changes. may be made and numerous details of construction may be varied through a wide range without departing from the principles oi? this invention and I, therefore, do not'purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a railwaycar vestibule curtain and the handle thereof, of a swivelr-id hook adapted to be removably engaged by the handle to hold said curtain eX- tended and to have swivel action while so engaged.

2. The combination with a railwayear vestibule curtain adapted to be mounted on one end of a car, of a mounting plate, a curtain retaining hook pivotally mounted on said mounting plate, and a handle on said curtain to extend the same permitting said handle to be reniovably engaged with said swiveled hook, said hook being free to pivot while so engaged with said handle.

3. l The combination with a railway car ves- -tibule curtain, of a handle removably engaged thereon, a mounting plate, and a hook swiveled on said mounting plate for free pivotal movement adapt-ed to be removably engaged by said handle and permitting move- 111M110 of said handle with respect to said mounting plate with substantially no frictional sliding movement taking place between said handle and hook.

4. A swivel hook structure comprising a base plate,.said plate havingan aperture therein, an internally threaded stud having one of its outer ends reduced in diameter to enter said aperture, a shoulder on said stud, said stud being secured to said plate by having the end projecting through said aperture swedged against the back side of said plate and with its shoulder against the front side of said plate, a hook pivoted on said stud, and a retaining screw threaded into said Stud for retaining said hook on said stud.

In testimony whereof I have hereunto subscribed my name.
