CAR-DOOR.

Specification of Letters iatent. Patented J an. 28, 1913.

Application filed February 15, 1912. Serial No. 677,730.

To alt whom it may concern:

Be it known that I, SAMUEL WALTERS, a citizen of the United States, and a resident of Warren, in the county of Warren and State of Pennsylvania, have invented a new and Improved Car-Door, of which the fol lowing is a full, clear, and exact descrip- 'tion.

My invention relates generally to car door structures, and more particularly is directed to a new and improved construction wherebythe door, when in closed position, lies flush with theoutside of the car. I

The principal object of my invention is to provide a new and improved car door embodying means whereby the door when in closed position will lie flush with the side of the car, means being provided for moving the door preparatory to opening it, suitable rails being provided whereby the door may be rolled to uncover the opening, the door 'moving into a, position remote from the side of the door.

A further object of my invention is to provide a new and improved car door construction, the arrangement of the parts he ing such that communimtion between the interior of the car and t e outside is prevented by the arrangement of the upper track on which the door moves, this track effectively closing the opening between the top of the door and the door casing.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side view of the car door in closed position Fig. 2 is a sectional view on the line 22 of Fig. 1, the door being in open position; Fig. 3 is a similar view, the position of the door previous to closing bcing shown; Fig. 4 is a similar view showing the door in closed position; Fig. 5 is a sec tional view on the line 55 of Fig. 2; Fig. 6 is a sectional View on the line 66 of Fig. 2; Fig.7 is a view showing the upper portion of the car door when in the position shown in Fig. 2; and Fig. 8 is a bottoxnplan View showing the detail of the arrangement of the rail and the shoe carried by the door.

Any suitable car comprising the side 2 is provided with an opening whereby access to the interior is had, the opening being adapted to be closed by the door 3 movably and slidably mounted in position, opposite sidewalls of the opening being provided with 1 pockets 4 into which the opposite side portions of the door are adapted to be seated when the door is closed, as shown particularly in Figs. 1 and 4.

The'outside of the car adjacent the top and bottom thereof is provided with

rails

5, 6, the lower rail 5 being positioned remote from the side of the car for the greater portion of its length by means of suitable braces 7, the end ortion 8 of this rail being bent and being brought into engagement with the side of the car adjacent the lower portion of the opening. The upper rail 6 is preferably positioned on a suitable support 9 secured to the side of the car in any desired manner, the rail being bent similarly to the rail 5 and being substantially parallel therewith. Each of the

rails

5, 6 is prefei'- ably of T-shape in cross section, as shown particularly in Fig. 5,the flanges of the rails being in engagement with the braces 7 and the support 9 respectively by any suitable means, such as bolts or screws 10.

Adjacent one end of the car door 3 and at the top and bottom thereof are the shoes 11, 12 secured to the door in any suitable manner, preferably by means of bolts 13, 14, the lower portion of the lower shoe'12 being recessed, as at 15, whereby it may embrace the or damaged "from continued use. This shoeis also provided with a recess 100 adapted to embrace the rail 6 in a manner. similar to the shoe 19.. The opposite end portion of the door, and adjacent the top and bottom thereof and on the outside, is provided with fixed bearings 17 within which the rods 18, 19 are rotatably mounted, the rods being preferably Separately made and held to gothor in a manner substantially as follows: The lower end of the rod 18 is enlarged and provided with a substantially rectangular pocket 20, while the upper end 21 of the rod 19 is rectangular in cross section and engages the pocket- 20, thereby providing for easy assemblage of the parts, turning of either rod insuring turning of the other rod by reason of such engagement. In order to turn the rod, a suitable lever 22 is pivotally mounted thereon at-23, the door being provided with a plurality of pockets 2 adapted to eceive the end of the lever in open or closed position, whereby the maintenance of such position is insured.-

The upper end of the rod 18 is provided with an off-set arm 25 which'ds in pivotal engagement. with a shoe 26 which shoe is provided with a recess 27 whereby it may embrace the T-shaped upper rail 6 and slide therealongh The lower end of the rod 19 is provided with an ofi-set arm 28 in pivotal engagement with the shoe 29 by means of a pin 30, the shoe being provided with a recess 31 whereby it may-embrace and slide along the lower rail 5.

Referring particularly to Fig. 5, it will be noted that the lower end of the rod 19 extends beyond the lower portion of the door 3, while the u per portion of the rod 18' extends below t e top of the door 3, the side of the door being preferably provided with a suitable pocket 32 whereby ease of operation and non-interference of the parts is 1 provided for.

From the above description it will be noted that the'rails 5, 6 are fixed in position to the side ofthe car, while the rods 18 19 are rotatably secured to the side of the door, it. being "clear that ifeither rod 18, 19 is turned, the door 3 will'be moved closer'to or removed from'the side of the car," due to the off-set arms 25, 28 at the ends of the rods 18, 19. Referring more particularly to Fig. 2 which shows the door in open position, it will be noted that the door is 'adja-. cent the side 2 of the car. In order to bring the door into closed position, it is moved to the left, the rods 18, 19 and the arms 25, 28 thereof beingin the position shown in Fig; 3, at the end ofthe travel. By turning the lever 22 the rods will be "turned and the arms 25, 28 will .swin the adjacent end of the door into the 00 et- 4 Fig. 4:. In this position of the ugthe side wall of the opening, t e door b ting then in closed position as shown in I outside of the door is flush witht e outside arts, the

- will be noted that the portions 11, 11 of the '60 bottom of these shoes are curved as at 11 so that when the end of the door movesjalong the curved or bent portion of the

tracks

5, 6, the curvature prevents binding of the parts and provides for easy operation thereof. I

The door may be provided with any suitable form of locking device, the preferred form embodying a hasp 40 having an opening therein engaging a suitable hook or staple 41 whereby withdrawal of the hasp 40 therefrom is prevented. I y Of course, the particular size and'shape, as well as the material of the difierent'elaments making up the structure of the car door may be varied, depending upon the size and structure of the cars with which itisused, suchclianges, however, being com-- prehendedwithin the spirit ofmy invention.

Having thus described my invention, I

nation with rails along which the door travels, comprising a plurality of rods, one of 35 the rods being provided with a ocket which 7 engages one end'of the otherro with'a nonrotative engagement, the end portions of the said rods being provided with ofi'set arms, the said ofiset arms engaging shoes mountedon the said rails, 0"ne of the rods being provided with a pivoted lever, and the door being provided with a' number of pocketsany one ofwhich is adapted to engage the said lever, whereby the position of the rods and the said offset arms is maintained.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.
