To all whom it may concern.-

Be it known that 1, CHARLES W. TEFFT, a citizen of the United States, and a resident of Toledo, in' the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car-Doors; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in car-doors of the class comprising a series of; flexibly-connected sections mounted in run-- ways and adapted when opened to be moved up out of the way under the car-roof.

The object of my invention is the provision of a door of this class that is adapted when closed to entirely and tightly close the door opening and that is provided with means whereby such door maybe securely locked at its upper part against movement and such locking means controlled without the door in a manner enabling it to be sealed by the usual car-seal.

The operation, construction, and arrangement of the parts of the inventionare fully described in the following specification and shown in the accompanying drawings, in which Figure 1 is a side elevation of a portion of a car embodying my invention with the door shown in closed position. Fig. 2 is a horizontal cross-section of a portion of a car, showing the door-openings. Fig. 3 is a vertical cross-section of a portion of a car, taken on the dotted line as x in Fig. 1 and showing one door partially raised and the position of the weight-cable of each door with the guidingpulleys therefor removed. Fig. 4 is an inner elevation of a door and door-frame comprising my invention. Figs. 5, 6, and 7 are de tails of the lock-sealing means. Fig. 8 is a top view of the portion'of a car including the opposing door-frames and doors with the roof removed to illustrate the course of the weight-cables and the positions of the guiding-pulley's therefor; and Fig. 9 is a vertical cross-section of the up or portion of a car, taken along the dotted ine r so in Fig. 8 and showing the positions of the guiding-pulleys gor the contiguous weight-cables of the two oors.

and 6 the doors.

Referring to the drawings, 1 represents the body or box of a car, of which 2 is the flooring; 3, the sides 4, the roof; 5, the door-posts, Each post 5 is formed with a vertical guide or runway 7, in which the conti uous edge of a door 6 operates as it is raise or lowered. The outer edge or rib ofeach runway is shown in the drawings as being formed by a metal strip 8, which is straight throughout its length and secured in any suitable manner to the outer side edge of the door-opening. The runways 7 of each door of 'a car communicate at their upper ends with horizontally-disposed guides or runways formed'in or provided on the contiguous faces of the roof-beams 9, which are properly positioned in the car-body for that purpose, one set of runways 7 communicatin with a set of runways 10 on said beams an the-other set communicating with a set of runways 10 thereon, as shown in Fig. 3.

The runways 10 and 10 communicate in a .curved line with their respective runways 7,

the inner shoulder or edge of which latter runways 7 diverge from the strips 8 or outer rib thereof adjacent to the top of the dooropening, as shown, thereby providing a notch or recess 7*- at the upper end of each runway 7.

The doors 6 are each composed of a series of sections 11, flexibly connected together by links or hinges 12 or in any other suitable manner. To the inner face of each door 6, adjacent to the top thereof, and at each side is attached a cable 13, which when the door is closed passes thence over a sheave or pulley 14 on the contiguous roof-beam 9 across to the opposite side of the ear, and thence is guided through a transverse or diagonallydisposed opening 15 in the beam 9 by the suitably-positioned ulleys or sheaves 14 and 14 the latter 0 whichdirects the cable down into a pi e or weight-socket 16, where it'connects with a counterbalance-Wei ht 17, as shown in Figs. 8 and 9. It will t us be seen that the counterbalance-weights of each door operate in sockets disposed on the opposite side of the car thereto in close parallel relation to the door-posts 5 on such side. The pipes or sockets 16 extend from the top of the car to a distance below the floor thereof necessary to accommodatethe length of movement of the weights when a door is opened to its fullest extent.

As the curve at the upper end of the mner shoulders or ribs of the runways 7 of each IIO door would permit the sections-11 of a door which are disposed above the point of commencement of said curves to fall back out of the notches or recesses 7 at the top of the runways, I secure one or more flat springs 18 to the section 11 of a door, first squarely abutting the straight inner shoulder or rib of the runways, the free ends of which springs extend upward and abut the rear faces-of the 1 remaining top sections, whereby to normally retain said sections pressed outwardly against the strip 8 of the door-casing and within the notches or recesses 7 when the door is closed. By this means the door when closed is normall locked against rising by reason of the top dbor-section having a direct vertical thrust against the top of the doorframe, as shown as the right of Fig. 3. V

In order to prevent the unauthorized 0 ening of a car-door by an inward pressing o the top sections thereof, thus permitting a raising of the door, a lock 19, having a springactuated slide-bolt therein, is secured to the top door-section inposition for its bolt to engage an alining notch 20 in the top of the door-casing. This bolt is controlled from without the car by a cord or wire 21, which is attached at one end to the bolt and. has itsother end passed through an opening 22 in one of the lower sections of the door and is prevented from withdrawal therefrom by a ring or other suitable enlargement provided at such end. Countersunk 1n the outer face of the door-section through which theend of the rope passes and having an opening therein registerin with the opening in the doorsection is a s ideway 23, preferably of metal, having one end turned up to form a lip 24 at right angles to its body portion. Mounted for movement in the way 23 is a slide 25, which has one end bent at right angles, as shown at 26, to abut against the lip 24 and which is adapted to be moved to open or close access to the recessed portion 27 at the rear of the opening through the slidewa and in which the ring or enlar ement at the I 0 end of the cord 21 is con necl when'the door is closed. A sealing of the lock against being tampered with by unauthorized persons is 5 efiected by moving the slide 25 to close the opening over the recessed portion 27 and inserting a sealin wire through apertures28 in the abutting Ii s 24 and 26 to prevent an opening of the side.

In the opening of the door comprising my invention the seal is first broken to permit a movement of the slide 25 to uncover the lower end of the cord 21. This being done,

the cord is pulled to eflect a release of the bolt in the lock 19 and to draw the top sections of the door inwardl sure of the springs 18 unti they are free rom the notches or recesses 7 and bear against the curved surface of the inner shoulders or ribs of the runways, thereby permitting the again st the pres- 7 door to be raised to the top of the car. A very light upward pressure on the door is suflicient to raise it, as its weight andthe frictional resistance of the runways are counterbalanced by the weights 17.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
