Be itknownthat I, HENRY F. J EROLAMAN, a citizen of the United States, and arcsident of the city of Chicago, in thecounty ofCook and State of Illinois, have invented a certain new and useful Improvement in Mechanism for Operating Freight-Car Doors; andl do hereby declare that the following description of my said invention, taken in connec tion with the accompanying sheet of drawings, forms a full, clear, and exactspecification, which will enable others skilled. in the art to which it appertains to make and use the same. a j My invention relates generally to imrovements in mechanism. for. operating reight-car doors; and it consists, essentially, in the'novel and peculiar combination of parts and details of construction, as herein after first fully set forth and described and then pointed out in themclaims. v The object of this invention is the production of an efiicient, and serviceable mechanical means for opening and closing the doors t 1e, at presof box cars, which, especially in out, prevailing employment of freight cars having a very large capacity, and consequently increased weight, are rather difiicult to open and close without resort to some,

means for asslsting in this opening. This means has generally been a crowbar, and the result of the application of this means may be noticed bythe inspection of freight cars that have been in use for some time and show the result and the damages tothe, car; sides and the doors resulting from the use of this A further ob ject of this invention is the introduction of means for lockin and sealing the car doors instrument of destruction.

to prevent unauthorized entry into the. car, said locking means being a part of the mechanism for operatlng the doors. v

Other objects of this invent'on will herein after appear.

To the facinglS of the car body, and

above the door ,B,.there is secured a fulcrum 110 bracket and; the lower .endof the pendulum. lever. Fig. 9. is a detached sectional view of.

' Ektendingfrom,-'andsecuredto, the sill '14, and; located below the door, there is a bracket 37-,"sho'wn inde'tail-in Figs. 7 and 8,1Which bracket hasfn'ear the o'uteren'dof itshorizontal member, an opening 3 8, and in thereis 1P 0 over the outer end of {the bracket '37.

i Upoir the pendulum lever there is 'slidably placed a socket H, Whi'ch ha'salaterally eX-; tendingv bar 41, from which extends. downfront of this opening, a transverse slot 39. Near thelower end onthe pendulum lever D, there transverse. slot- 40, large enough toperinit the endulum lever being placed Wardly, a pin 42, and in front of this pin in thebar 41, a transverseslot 43,

sa- 'i-ength a seeond handle 33, the lever f-from a platformf pin 12 and the slot 43, positions of the opcnthe horizontal limb of the bracket 37 Let itnoW be assumed that the door B, in being opened, moves to the right, as shown in Fig. 2. There is placed near the right-hand vertical margin of the door, an angle iron 44, Figs. 1 and 2, against which the pendulum lever bears when the door is closed and the pendulum lever is in vertical position and engaging the bracket 37. This will prevent the door from being opened; andwhen the socket H with its pin 4213 moved downwardly so that the pin 42- enters thehole 38 in the bracket 37, the pendulum lever D is locked in its depending position, so; that when a car seal 45, Fig, 3, is passed through the slot 39 in the bracket 37 andthe slot 43 in the socketbar 41, the car door is also sealed, thereby doingaway with the present mechanism for sealing a car, such as staples and hasps, and the like. Instead of this angle iron 44, I may move the projection 22 on the door somewhat to the right, so that when the pendulum lever is in pendant position, and the door is closed, this lever will bear against this projection and thus serve the purpose of the element 44, a construction which would be perfectly obvious.

Attention is now invited to the fact that the upper end of the pendulum lover I) is slotted, the object of which is to permit a certain amount of vertical movement of the pendulum lever so that the latter will always be in condition tobe placed over the bracket 37 when the pendulum lever is to be' held in vertical, depending, position. And it is to be noted that the upper end of this lever which is pivoted upon the bolt 28, has some lateral play between the flange 27 ofthe spool G,'and the washer 30, on the bolt. This permits the lower end of the lever" to be swungaway from the door a certain distancefjust suflicient to clear the parts-projecting from the door, when the lever is to be employed for opening or closing'the'dooit: l V

The operation of this closure operating mechanism may now be briefly described, as follows: I l

"The car door being closed and the pendulum lever in locked position, the slidable socket H is lifted to disengage its pin 42 from the bra cket37, and the lower end of thepp'enduluni lever swung outwardly and t'of'the left, behind the first projection 22, and then pulled toward 'the right to take the first bite, which willn'iove the door B some distance in the sanie direction. The pendulum'lever is then again moved toward theleft'behind thesecond projection 22", and this step-by-step movement is repeated until the door is entirely opened.

To close the door, the pndulumlever is first placed behind the projection 22; and then the manipulation of the lever repeated, as hereinbefo're stated, until the door is closed, and the pendulum lever placed onto the bracket 37 and the socket H lowered to cause thepin ietoeugage the noises in the bracket 37. f

The ,object of the, roller on the stud bolt 37, shown in Fig; is to reduce friction on the pendulum lever when moving the door, as far as possible, amiss dulum lever from slipping off the roller when being operated.

While I have hereinbefore described the preferred embodiment of my invention, I

desire it to be understood that I am aware that changes may be made in the details of construction, to adapt this invention to the different freight cars now in use, and that parts may be omitted Without departing from the scope of my invention, as defined in the appended claims.
