CAR-DOOR FASTENER.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed July 14, 1908. Serial No. 443,488.

To all whom it may comwn: 1

Be it known that I, Cultures lion; TROON, a citizen of the United States, residing at Pomeroy, in the county of Calhoun and State of Iowa, have invented a new and useful Improvement in Car-Door Fasteners, of which the following is a specification.

This invention relates to car door fasteners, especially adapted to be used on freight cars, the object being to provide a fastener which will securely lock the door.

Another object of my invention is to pivotally mount on the sill of the door a pair of arms adapted to extend up above the lower pro )er position, whereby the door can be reatily opened by swinging the arms out of engagement with the door.

Another object of my invention is to connect an operating lever to the arms provided with a spring actuated bolt adapted to we tend through the ordinary staple and secure the liasp in place.

\Vith these objects in view, the invention.

con'ibination and arrangement of parts here-- inafter fully described and pointed out in the claims.

1n the drawings forming a part oi this specificationz-Figure l is a side elevation ot a portion of a Freight car showing the application of my improved fastener. Fig. 2 is a. section taken on line 2--2 oi Fig. 1. Fig. l is a detail side elevation, and Fig. t is a section taken on line el--4 of Fig. '1.

In the drawings A indicates an ordinary car provided with the usual sliding door B carr ing a hasp (l adapted to .lit over the stape l) for locking the door. Secured in the sill of the car under the dooropening are bolts E and F on which are pivoted mounted arms E F which are provided with enlarged portions E F having recesses formed therein in which are mounted anti t'rietion rollers i l 1 adapted to extend up along side of the door B when in a vertical position so as to prevent the lower portion of the door from being forced outwardly by the pressure of the material Within the car and to allow the car door to slide easily. The arms E and i arc'provided with openings in which the ends ol the connecting link G are secured for connecting the arms together so that they will be operated .in unison, the arm l*1 ,l. eing provided with an arm E to which is connected it link ll carried by an arm l. of a lever l which is i pivotally mounted on a bolt l" secured in the si l and is provided with :1 reduced upper end forming a shoulder J in which is formed a vertic: l bore having a bolt K slidably mounted therein which is surrounded by a coilspring K, one end of which is secured to the bolt, and the other rests on the shoulder, so

as to normally hold the bolt in an extended )osition. The belt is provided with a slot {2 at its upper end adapted to receive a seal li when forced through the staple for securely locking the door. The upper portion of the bolt extends through a guide-eye K formed on the upper end of the lever, so as to limit the upward movement of the same, which prevents it from being forced out of the bore of the lever by the spring.

The operation is as follows: Suppose the fastener to be in position as shown in Fig. 1 and it desired to open the door, the seal is broken and the bolt drawn downwardly out of the staple so as to allow the hasp to be removed and by forcing the lever to one side. as shown in dotted lines in Fig. 1, the arms will be swun out of engagement with the door so that t e door can be readily opened.

From the foregoing description it will be seen that I have provided a very novel cardoor fastener, the parts of which are so arranged and connected that they can be easily and quickly operated. It will also be seen that by eonnectingthe pivoted arms to the operating lever they will be swung out of engagement with the door when the lever is operated, so as to allow the door to be moved easily, thereby overcoming the ditiiculties now existing with devices of this character, as it almost impossible to open the door when the pressure of the material within. the car is against the door as the door jamhs againstthe guide member.

Having thus l'ully described my invention, what 1 claim new and desire to secure by letters Patent is:---

The combination with a car provided with a sliding door, ol' arms pivotally mount;- cd under saiddoor provided with rollers l'or engaging the door and a leverlor operating said arm carrying a locking bolt for locking said door.

2. The combination with a car provided with a. sliding door, of armspivotally mounted under the door opening of said car, a link connectin said arms, and a lever connected to one of said arms provided with a spring actuated bolt for locking said door.

" extend up above the lower edge of the same, a link connecting said arms, a lever pivoted 3. T he combination with a car provided I arms pivotally mounted below the door with a staple, of a door provided with a hasp I opening of the car extending above said adapted to fit over said staple, arms pivot door, a link connecting said arms, a lever ally mounted under said door adapted to pivoted to said car provided with an arm, a

ink connecting one o'l' said arms to the arm of the lever, a bore formed in the free end of to one side of said door, a link connecting K said lever, and aspring actuated bolt mountsaid lever to one of said arms, and a spring ed in saidbore provided with a slot adapted actuated bolt carried by said lever ada ted I toextend through said staple.
