Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed November 17, 1915. Serial No. 61,912.

To all whom it may concern:

Be it known that I, JOSEPH F. CoMEE, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in (flacDoor Operating and Locking Mechanism, of which the following is a specification.

My invention relates to car doors and has particular reference to improvements in car door operating and locking devices.

The object of my invention is to provide a combined door operating and locking device or mechanism, which shall consist of but. few parts, which shall be strong and durable and low in cost, and by means of which the operator can easily apply great force either to open or close the car door and without risk of destroying or injuring either the door or the car A further object of my invention is to provide a car door operating device by means of which the door can be positively and quickly closed or partly opened and securely locked in either of said positions and which shall be free from any possibility of destructive wear when in locked position.

My invention resides in a mechanism for opening, closing and looking a sliding car door, which comprises a hasp and an operating lever cooperatively arranged on the door and the car for opening and closing the door and the hasp being adapted for engagement with a locking! staple on the opposite member to positively hold the door closed or partly open.

My invention also consist in a toothed rack-like hasp and a pinion mounted upon the door and the car and adapted for operative COiiPBl'iltlOfl to open and close the door, the pinion forming part of a lever by means of which great force can be applied to the door and a fixed staple arranged adjacent to the pinion, which serves the double purpose of a guide for the hasp when in mesh with the pinion and for engagement with the hasp to hold the stoor stationary.

My invention also consists in a hasp for freight car doors which serves the double purpose of a door lock and door operator.

My invention also consists in a rack-like hasp pivotally mounted at one end on the car door, a pinion on an adjacent part of the (-a r with which the hasp can be brought into engagement means for rotating the pinion to open or close the door, a fixed staple for engagement with the hasp to hold the door in either of. two positions, said staple being adapted to guide the rack while engaged with the pinion and'means for locking the g rack in pinion engaging or staple engaging position.

My invention also consists in the several features of construction and the combinations, arrangements and relations. of parts 35 My invention will be more readily understood by reference to the accompanying drawings forming part ,of this specification, and in which:

Figure 1 is a fragmentary side elevation of a freight car equipped with a door operating mechanism embodying my invention and showing the door locked in closed position; Fig. 2 is an enlarged fragmentary view showing the door closed and g the mechanism in door operating relation; Fig. 3 is a similar fragmentary view showing the door partly open and the mechanism in door operating relation; Fig. --'1-- is a similar fragmentary view showing the 3'5 door partly open and locked in such osition; Fig. -5- is an enlarged sectional view on the line 5 5 of Fig. 2; Fig. 6- is a vertical section on the line 66 of Fig. 2-; and Fig.' -7 is a perspoC-' 9'0 tive view of the toothed hasp.

The rough usage to which freight cars and their doors are subjected and the fact that they are exposed, in use, to allkinds of weather conditions results in a warping and twisting of the various car elements, particularly in \vooden'cars, so that although the sliding doors on freight cars usuall opcrate easily when the car is first built; and

put into service they quickly reach that'com 10o dition in which they-bind in their ways and the door post may and often does interfere with the easy opening and closing of' the door, consequently it is difficult to move the door back and forth'. This difficulty in opcrating the door results in the rapid destrufition of car doors and cars, for, when an dar reaches its destination if the door can-' not be easily opened, the one who desires to open' it frequently uses forcible methods,

such as wedges and hammers and such like tools, destroying and breaking up the door and the adjacent parts of the car, for of course, the goods within the car must be delivered regardless of the condition of the car. In view of this situation many mechanisms have been devised for the application of force to the car door to open and close it with ut destructive effects, but these mechanisms, so far as I am aware, are quite compucated comprising many parts some of which in the nature of things, cannot be made substantial enough to stand the severe strains to which they are subjected in use. To overcome these difficulties I have devised the simple door operating and locking mechanism illustrated in the said drawings, and which primarily comprises a hasp which is pivotally mounted. at one end on the car door and which serves the purpose of an operating rack, and a toothed lever pivotally mounted on the door post adjacent to the door opening and adapted to engage the rack. and by means of which relatively great force can be easily applied to the door, in the direction of its movement and without any danger of destroyin; the door or the adjacent parts of the car. Furthermore these operating parts are permanently secured upon the car members ready for instant cooperation when it is desired to open, close or lock the door. As a further feature I make use of my operating hasp with which to lock the door both in its closed position and in a partly open position, in which latter position it is desired to hold the door locked so that the car can be ventilated.

In said drawings A represents a freight car, and B one of the sliding doors thereof, which is adapted to slide back and forth in front of the door opening C. The door is mounted at its upper end upon a rail 1) by means of door sheaves E, and the lower end of the door is provided with a longitudinal ledge or flange F which is received behind a guide plate G. At the forward end of the door opening C is a door post (1 having an outer post or jamb H against which the forward edge of the door is adapted to abut when the door is closed. The door overlaps the adjacent part of the post G, and as cars are usually constructed, the inner face of the door and the outer face of the post (1 lie very closely together so that the contents of the car cannot escape at this point, and coir sequently, if the post G or the forward edge of the door itself warps or becomes twisted to any appreciable extent, these two parts interfere with each other and create a great deal of friction. It is thefriction or interference at this particular point that my operating device is adapted to overcome and for which I have 'particularly devised my door operating device. Furthermore, in the modern construction of freight cars the forward edge of the door is usually held inwardly against the door post G by means of a wedging surface which projects over the forward edge of the door and holds the door from springing outwardly when in its closed position, which springing of the door might be due either to the warped condition of the door itself or to the pressure of the contents of the car. Consequently, unless the forward edge of the door and the adja cent surface of the post freely pass each other the interference which has been ex plained will exist.

I provide a hasp 2 pivot-ally mounted at one of its ends 3 on the face pf the forward part of the door so that it can swing freely, and the hasp is adapted to be swung upwardly to a substantially horizontal position to project beyond the forward edge of the door for cooperation with the locking and operating devices which are mounted upon the post H. I provide the hasp, on its lower edge, with a series of teeth 4 which constitute a rack, by means of which I am enabled to apply force either to open or close the door.

Upon the post H I mount a lever 5 on a horizontal rigid pivot 6, I the lever being adapted to project close to and swing parallel with the adjacent face of the car. I provide the pivoted end of the lever with a segmental toothed pinion 7, the teeth of which are adapted to engage with the teeth on the hasp 2 when it is desired to open or close the door, and the lever and pinion are preferably integral with each other so that this operating member is exceedingly strong. Above the pinion and spaced therefrom I provide a. rigid projection 8 which projects outwardly from the post II and constitutes a. locking staple. This staple also forms a guide for the hasp 2 when the teeth thereof are in mesh with the pinion and the hasp is being used as arack, as clearly illustrated in Figs. 2 and 3. In Fig. 3- I have illustrated the relative positions of the hasp and lever which these parts occupy at the time that the door is moved to its partly open position or when the hasp and iever are arranged to begin the closing of the door. I have also provided a locking member 9 which is mounted upon the door post H to slide up and down, and is provided at its lower end with a projection 10 adapted to pass through a perforation 11 in the staple 8 and is adapted to overlie or project in front of the hasp 2 when the same is in cooperative relation with the pinion 7. As clearly showmjn the several figures, this locking member-ff; is slidably mounted upon av fixed pin 12 and is provided with an elongated slot 13 to permit it to be moved entirely out of contact with the projection 8 for the purpose of permitting the movement ot' the iiasp into anil out of locking position.

The llasp constitutcs a combined tloor locking and operating menilwr aiuiptml in one position to cooperate with tho o jwmting lava-r for opcning and closing the door. and in ancthcr position to cooperate with the final projcction for locking the door. and at othcr times tree to hang in such relation to the iloor that it cannot olisti'urt thc door opcnii'ig.

To holil thc (loor firmly in against the overlapping part. of the post (i, when in ClOSWl positi n. l proviile a laterally extending projection l forming part of the stop .l and ovcrlapping the door space, the inner surfacc of this projection is inclined relatively to the door and is adapted to force the forward edge of the door inwardly against the outer surface of the post G. 'Io brace the stop J against the pressure which is applied to the projection I when the door is closed I provide a rearwardly extending projection R on the stop J adapted to rest upon the adjacent surface of the car and brace the stop .I against the tipping pressure applied to the projection P.

A further advantageous feature of my inention resides in the fact that the pinion is only in mesh with the hasp during the operation of opening and closing the door, and at all other times hangs free. on its pi\ot. consequently there is no undue wear up n the teeth of the pinion or the hasp which might result from the constant vibration of these parts were they in mesh all the time the door is closed.

A further important feature of my inven; tion is that the hasp is free to be entered sidewise into engagement with the pinion in any relation relatively thereto: in other words it is not necessary to guide the hasp into rngagen'ient with the pinion as the door is being closed. lsually the door in closing. slides very easily until its forward edge strikes the overlapping door post. then the hasp is swung up from its free vertical hanging position. it is also swung out to pass the operating lever and is then entered sidewise into engagement with the teeth of the pinion and beneath the locking staple. In this operation it is very easy to hold the operating lever at such an angle that the rack and pinion will be properly engaged to permit a complete closing of the door without the necessity of freeing the rack from the pinion and reengaging them in a. different relation or, on the other hand, it is very convenient to reengage the lever with the pinion in such relation that a maximum pull can be most easily applied to the lever. For instance it might occur that it would be best to rei image the pinion with the hasp several times during the door-moving operation so as to keep the l ver as nearly horizontal as possible. lint should such reengagcment be, necessary or desirable it can be very quickly and easily accomplished as the hasp is free to be swung out and in for such purpose. Ilaving engaged the rack with the pinion the locking member may be, inserted through the locking staple and its lower end holds the hasp from working sidewise out of engagement with the pinion during the door closing or moving operation. The door having been forced tightly against the door post or jamb the locking member is withdrawn. and the hasp is swung sidewise out of engagement with the pinion and is entered upon the locking staple then the lower end of the locking member is inserted through the locking staple to hold the hasp on the latter and thereafter the locking member can readily be sealed against Withdrawal by the insertion of the seal through the locking member and the registering opening in the adjacent projection on the hasp.

As many modifications of my intention will readily suggest themselves to one skilled in the art I do not limit or confine my invention to the specific structures herein shown and described.
