1'0 all], whom it may concern:

Be it known that I, LOUIS A. HOERR, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Door- Hanger, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to door hangers an i more particularly to the means for suspending the sliding door of such car.

Heretofore railway cars have been made in which the door was normally supported by asliding bearing and adapted to be shifted from such sliding bearing to rolling bearing through levers which raised the car door.

The object of my invention is to provide a sliding bearing normally supporting the door, and a rolling bearing and to provide means controlled by the lateral movement of the door for shifting the door from the sliding bearing to the rolling bearing.

In accompanying drawings which illustrate one form of door hanger made in accordance with my invention, together with part of a railway car to which the same is applied, Figure 1 is a side elevation; Fig. 2 is a vertical section on a slightly enlarged scale; Fig. 3 is anenlarged side elevation, partly in section, of one of the hangers, and Fig. 4 is a side elevation of one of the hangers the tilting member being shown in a different position.

Like marks of reference refer to similar parts in the severalviews of the drawings.

10 represents the car body which is provided with the usual roof 11 and facia board 12.

13 is the door which is provided with the usual handle 14 for moving it laterally.

At the left side of the door the car body 10 has secured to it the usual door stop 15. Arranged between the facia board 12 and the top of the door 13 is an inverted channel bar 16 which serves for a track for the hangers, as will be hereinafter described, and also acts as a shield for'the top of the door to prevent the entrance of rain or snow. The channel bar 16 is secured to the side-of the car by means of bolts 17. The hangers which are preferably two in number, each consists of a plate 18, provided with bolt holes 19, and a hood 20. Loosely carried by each of the hangers Figs. 1 and 2.

18 is a tiltinggmember 21 providedg withia sliding bearing 22 and a pair ofg wheels 23 forming rolling bearings. Extending upwardly from each of the tilting membersgl is a triangular projection 24 which is engaged by the hood 20. Each of the hoods 20 is provided. with a rounded bearing surface 25 which normally rests on the concave upper face of the triangular projection 24. At each side of this bearing surface 25 are concave recesses 26 adapted to engage with the rounded corners 27 of the triangular projection 24 when the door is moved laterally so as to tilt themember 21 into the position shown in Fig. 4 and thus shift the car door from the sliding bearing 22 to one of the rolling bearings 23. At the same time the entire door will be slightly raised as will be evident from a comparison of Fig. 3 and Fig. 4. Secured to the body of the car 10 adjacent to the lower edge of the door 13 are a pair of brackets 30. These-brackets 30'are adapted to form sliding bearings for door 13 when said door is in its closed position, as shown in When in this position, Said brackets 30 co-operate with corner pieces 31 secured to the door 13. These corner pieces 31 project Slightly below the lower edge of the door 13 as shown in Fig.- 1 so that when the door 13 is moved out of its normal position its lower edge does not engage with the brackets 30. I

The operation of the door will be evident from the above description. When the door 13 is in its closed position, as shown in Fig. 1, its entire weight will rest upon its brackets 30, the parts being so proportioned and positioned that in this position the hoods 20 are slightly raised so as to be out of contact with the tilting members 24 of the hangers. When, however, the door is moved laterally, either by means of handle 14 or in any other way, the members 21 will be tilted into the position shown in Fig. 4, thus raising the door 13 off the brackets 30 and shifting it on to the wheels 23 so that it will have a rolling bearing. As soon, however, as the door is allowed to come to rest out of its closed position it will drop and shift from the rolling bearings 23 to the sliding bearings 22. If now the door be again moved in either direction the members 21 will againv be tilted so as to shift the door from the sliding bearings 22 to the rolling bearings 23. It will thus be evident that the door does not rest upon the rolling bearings 23 at any time while it is at rest, and when in its closed position the Weight is entirely transferred from the hangers 18 to the brackets 80. The channel bar 16 protects the door 13 from the entrance of rain and snow in addition to forming a track for the hangers 18.

Having fully described my invention, what I claim as new and desire to secure by Letter Patent of the United States, is

1. The combination with a car body, of a door, a sliding support forsaid door, a rolling support for said door, and means controlled by the lateral movement of said door for shifting said door from one of said supports to the other.

2. The combination with a car body, of a door, a sliding support for said door, a hanger provided with a rolling support for said door, and means controlled by the lateral movement of said door for shifting said door from one of said supports to the other.

3. The combination with a car body, of a door, and means controlled by the lateral movement of the door for moving said door vertically.

4. The combination of the car body, of a door, a hanger for said door, and means carried by said hanger and controlled by the lateral movement of the door for moving the door vertically.

5. The combination with a car body, of a door, a hanger secured to said door, a tilting member carried by said hanger and provided with a sliding'support, and a rolling support mounted thereon.

6. The combination with a car body, of a door, a hanger secured to said door and having a hood, a member provided with a sliding bearing and having an upward projection adapted to engage said hood, and a rolling bearing carried by said member.

7. The combination with a car body, of a door, a hanger secured to said door and having a hood, a member provided with a sliding bearing and having an upward triangular projection adapted to engage said hood, and a rolling bearing carried by said member.

8. The combination with a car body, of a door, a hanger secured to said door and having a hood, an inverted channel bar secured to said car body forming a shield for said door, a tilting member provided with a sliding support co-operating with said channel bar, and a rolling support carried by said inember and co-operating' with said channel In testimony whereof, I have hereunto set my hand and affixed my seal in the presence of the two subscribing witnesses.
