HANGING AND SLIDING DOOR.

SPECIFICATION forming part of Letters Patent No. 568,152, dated September 22, 1896.

Application filed August 16, 1895. Serial No. 559,570- (No model.)

To atZZ whom it may concern:

Be it known that I, HARRY G. ASHENFEL- TER, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented anew and useful Freight-Car Door, of which the following is a specification.

My invention relates to improvements in car-doors which are suspended from overhead tracks by jointed suspension-hinges which operate in conjunction with a double-cranked rod and lever in closing the door into the cardoorway and that when so closed the door may be flush with the outer surface of the car; and the objects of my improvements are, first, to provide facilities whereby a more effective seating of the door is obtained; second, to provide means whereby the door can be more readily raised in shutting, and will open automatically upon releasing the operating-lever; third, to provide means whereby the door may be opened and closed when the car is placed beside a platform which would interfere with the operation of a raising and lowering lever if allowed to project radially from the operating-rod; fourth, to provide automatic means for locking the door open when clear of the doorway, and, fifth, to provide means whereby the door can be forced down and out of the doorway inoa'se of its sticking therein. I attain these objects by the mechanism illustrated in the accompanying drawings, in whi'oh Figure 1 is a sectional elevation of a car on line A B of Fig. 3, showing the door closed and the position of the parts by which this is accomplished. Fig. 2 is an end elevation of part of a car, showing my door in position when out of the opening. Fig. 3 is a front elevation of same, showing the car and door with a part broken out. Fig. 4 is a detailed sectional view of the crank and lifting-lever when about to operate in'closingthe door. Fig. 5 is a detail, on large scale, of the lever end and the securing-link. Fig. 6 is a side view, on large scale, of the door-plate of the suspension-hinge. Fig. 7 is a plan View of same. Fig. 8 is a plan View of the connecting-link of the suspension-hinge.

side View of same. Fig. 10 is a plan view of Fig. 9 isa the locking-hook and stop-block. Fig. 11 is a side View of same. tion of the Wheel-frame of the suspensionhinge, showing the wheel or sheave. Fig. 13 is a rear elevation of same. Fig. 14 is a side elevation of my suspension-hinge on large scale. Fig. 15 is a side elevation of a broken portion of a car and door, showing the door open and the engagement of my hook and stop-block.

Similar letters refer to similar parts throughand brackets E, which are set in recesses provided in the side frame of the doorway. The door 0, which fits in the doorway B,v

is suspended from the track 72 by the hinges F and is provided with a crank-rod D, which turns in bearings d by means of a lever d,

Fig. 12 is an end eleva pivotally attached thereto between the ears r and adapted to shut upon the rod by means of such attachment, said rod provided with cranks D, set at an angle with the ears 7' and adapted to engage the brackets E and operate therein, and a link (i provided to engage the notch e in lever'd when the lever'is lying longitudinally upon the rod. The lever cl is also provided with an elongated openingj, adapted to engage the pin-iron 6 when the dooris closed, and is held in place bya pin 2'? entering through the pin-iron tin front of the lever d, as shown in Fig. l. The pin i is provided with a chain 2 to prevent it being lost when removed from the pin-iron.

hen the door 0 is moved longitudinally along the car by means of the sheaves h operating on the track 71 and is clear of the doorway B, the door is stopped by contact with the stop-block 50 and the locking-hook pivoted thereto engages the hook-iron Z, which is fast to the door. This engagement is antomatic by reason of the hook 1% being held in a horizontal position by the contact of the lug m with the projection m, and as the door slides open the hook-ironl engages the lower edge of the point and the hook drops over the hook-iron as the door strikes the stop-block.

Thus any rebound of the door which may be caused from a sharp contact with the stopblock is avoided and the door is secure from any sliding movement when left open during transit.

WVhen desirable to close the door, the hook m is raised and the door can then be moved back along the track 71 until opposite the doorway B, when it is stopped by the anglestop a.

The suspensionhinge F (which I have termed the connections between the door and track) are composed of a door-plate f, wheel-frame f and intermediate link j",

which is pivotally connected to the plate f and frame f by pivots p and p and is provided with projections or lugs g and g, which I have termed the pressure and position blocks, respectively. WVhen the door is opened down and clears the doorway B, the position-block g engages a projection or angular lug h on the wheel-frame f of the suspension-11in ge F, and by this engagement the door is prevented from swinging the link f to a vertical position, and the pivots p and p are retained at an angle with the vertical position of the door, as shown in Figs. 2 and 14. As clearly indicated on the drawings, the lower pivot 13 is slightly in advance of the upper pivot p when the door is open. This allows the link f to operate instantly in closing the door and avoids what is commonly termed a dead-center.

When the dooris raised and almost closed into the doorway B by reason of the links f operating upon the pivots p and p, the pressure-blocks g engage the lower portion of the inner side of the track 72 and as the door is finally closed these pressure-blocks act on the rail in forcing the upper portion of the door firmly in place, thus preventing a loose seating of the door, which might occur by reason of the side play between the rail and guide-block h, which would prevent thelinks 4 5 f from seating the door snugly in place without my pressure-blocks. These pressureblocks also prevent any material strain or pressure upon the wheel-frames f which might be occasioned by heavy weights resting or falling against the inner side of the door when closed, the pressure-blocks g acting against the rail 72 as indicated in Fig. 1.

The wheel-frame f is provided with a guide-block h, a wheel or sheave 7L2, and the angular projection h. The guide-block 7t serves to guide the wheel-frame along the track and also to hold the door in a vertical position when the block g comes in sharp contact with the angular projection h. It is obvious that a door dropping from the position indicated in Fig. l to that in Fig. 2 would acquire considerable force, and when the bot tom of the door came in contact with the guide-bracket 7c the top portion of the door would have a tendency to buckle outward, and if not checked this force would throw the wheels or sheaves from the track. To avoid this the hook of the guide-block h is provided, and engages the track 77, on the inner side, as shown in Fig. 2. keeps the wheel from being lifted from the track when the door is raised in closing.

As hereinbefore described, the lever d can be closed and looked upon the rod D. This provision is made to avoid all danger from the lever projecting and swinging when the car-door is open, the pivot attachments of the lever providing for the opening and closing of the door when the car is close to a high platform or bank, as will hereinafterbe more fully described.

It will be noticed upon reference to Fig. 4 that the longitudinal center line of the lever cl is not in line with the center of the cranks D. D. This angle is equal to that between the pivots p and p, occasioned by the contact of the blocks h and g of the suspensionhinges F, the radius upon which the pivot 13 operates being equal with the radius of the cranks. Thus the cranks D operate in unison with the links f in raising and closing the door and in maintaining it in a vertical position during the operation.

The angle of the cranks and lever also provides for the automatic opening of the door, as when the pin 2' is removed from the piniron the weight of the door acting upon the cranks D turns the rod D in its bearings and the cranks D throw the door clear of the opening.

\Vhen desirable to close the car-door from the position shown in Fig. 3, when close to a platform or bank of earth, the crank-rod D is turned in the bearings cl until the cranks D engage the brackets E. The link (i is then slipped from the end of the lever d and the lever is opened. (This position of the lever and cranks is shown in Fig. 4.) The lever is then pressed upward and the cranks D operate in the brackets E, the hinges F operating as heretofore described, and the door is seated in the doorway, the cranks D forcing the lower part of the door snugly in place. The opening j in the lever engages the pin-iron 2 and the pin 1' secures the lever in place.

If there be plenty of space at the side of the car in which to operate the lever, it may be opened from the crank-rod before the cranks engage the brackets E, and the lever employed during the complete operation of closing the door.

To open the car-door from the position shown in Fig. 1, when there is plenty of space at the side of the car, the pin 2' is removed and the door allowed to drop by reason of its own weight and the angle of the cranks with the lever. The lower end of the door engages the guide-brackets 7c, and the door, cranks, and lever assume the positions shown in Fig. 2, when the lever can be looked upon the rod, as heretofore explained, and

This guide-block also the door'shoved to one side and fastened in the position shown in Fig. 15, the. guidebrackets is guiding the lower part of the door. If the space be limited at the side of the car, the lever is employed to lower the door until reaching the position indicated in Fig. 4:, when the lever is then closed upon the rod and the cranks are disengaged from the brackets, as shown in Fig. 3.

In case the door should bind in the'doorway by reason of the swelling of the door or the swagging of the car, the cranks D are operated in the brackets E in a reverse direction to that in closing the door, and the door is forced open at the bottom, and, if still binding at the top, the cranks operate against the top of the recesses containing the brackets E, and the dooris forced down and out ofthe doorway.
