FEE IGHT-GAR Specification of Letters Patent.
Patented May 18, 1909.
Application filed January .11, 1908. Serial No. 410,409.
To all whom it may concern:
Be it known that I, HENRY W'ILLIAM KIRCHNER, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Freight-Oars, of which the following is a specification.
My invention relates to freight cars and more particularly to cars having removable and interchangeable compartments or unit boxes. I
It has for its principal objects to provide simple and efficient devices to hold the units in position on the car and to prevent them fromtilting or toppling over.
The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.
In the accompanying drawings, which form part of this specification, and wherein like" symbols refer to like parts wherever they occur,Figure 1 is a side elevation of a portion of a car embodying my invention; Fig. 2 is an enlarged fragmentary detail perspective view of a securing device and associated parts; Fig. 3 is an elevation thereof partly in section; Fig. 4 is a detail perspective view of an interchangeable unit box or and, Fig. 5 is a fragmentary detail perspective view of a car frame showing seats for unit boxes and relative positions of the keepers or securing devices.
The car comprises a body or underframe which may be mounted upon any suitable trucks. This underframe may be of any desirable construction, but it is preferably a structural steel skeleton frame. As shown in the drawings it comprises metallic longitudinal girders or side sills 1 and wooden transverse members or cross sills 2. The girders or side sills are reinforced with angle members 3 and 4.
Mounted on the cross sills 2 and on the inner faces of the side sills are angle members 5 and 6, respectively. These angle members 5 and 6 are placed flush with each other at a short distance below-the upper edges of the side sills so as to form rectangular pockets or seats for interchangeable unit boxes or compart nents 7. The several boxes or compartments are of the same size and shape, so as to cooperate with any pocket or seat as desired. Each of the boxes constitutes a se arable unit and is provided on its ends wlth interlocking members adapted to cooperate with like members on the next ad- 1 jacent unit. For this purpose, the locking members are preferably arranged in two sets on each of two opposite sides of the unit 1 (that is, four sets. in all); one member of l each set being a latch or hook 8 and the other member a keeper 9.
changeability, the latch and the keeper of each box are uniform, and the latch of each set is uniformly to the right (or to the left, i as the case may be) of the keeper of its set, looking toward them. Otherwise, stated, the latches and keepers are similarly ari ranged vertically of the box, so that, if the box is turned end for'end, the latch on either ll side of the box will cooperate equally well with the keeper on the adjacent box. The length of the latches is likewise uniform and such as to engage with the keeper of the box or unit in the next adjacent pocket or seat of the car. The latches thus constitute spacing members or distance pieces as well as fastenin devices. The latches are preferably formed with holes 10 through them so as to receive grab hooks or hangers of a derrick or the like, whereby the boxes or units may be readily lifted from the car. Secured on the sides of the car body or under-frame 1, adjacent to the ends of the cross sills 2, are keepers 11. These keepers are perferably malleable castings or forgings and are preforated lengthwise as at 12 for the re ception of coupling pins or bolts 13. of the unit boxes or compartments is provided with perforated ears or projections 14 which project laterally therefrom at each corner thereof, so that the perforations 15 are in alinement or register with the perforation 12 of the kee' er 11. For the sake of interchangeability t ie several cars 14 and keepers are arranged at uniform cooperative po sitions. As shown in the drawings each of the bolts 13 is provided with an enlargement or head 16 at one end to form a retaining shoulder 17. Obviously, the perforations 15 in the cars 14 are of a sufficient diameter to permit the passage of the enlarged portion of the bolts thercthrough. If desired, the perforation 12 in the keeper 11 may be circular and of the same diameter as the perforations 15, but it is preferable to elongate the perforation 12 in the keeper vertically, as shown, to provide for any irregularity that may ocour in the positions of the ears 14, especially 1 such as may be due to rough usage and excess- For the sake of inter-' Each ive stresses upon the car or unit boxes. The range of elongation of said perforation 12 is governed by the depth of the pockets or seats for the unit boxes on the car body. The enlargement or head 16 prevents the coupling pin 13 from being removed without placing said pin concentrically of the perforations in the ears and keeper. If desired, the enlargement may be omitted and a cotter pin or other detachable securing device may be employed in lieu thereof. Preferably, the coupling pins 13 are attached to the car body by short chains 18 or other suitable flexible connecting means.
By providing the interlocking latches and keepers at the adjacent ends of the units near the upper portion thereof, the several units are braced lengthwise of the car. The arrangement of devices on the lower adjacent end portions of the units adapted to cooperate with the keepers on the car body frame and the removable locking pins, prevents the units from accidentally toppling over, but permits of the ready release of any unit when it is desired to remove the same from the car. So, too, by this arrangement, should a unit box or a number of unit boxes be withdrawn from the car body, and the continuous endwise bracing of the several unit boxes at the upper portion thereof be thereby broken, the lower holding devices will. be sufficient to hold the remaining unit boxes in place in their respective seats or pockets.
Obviously, the construction and arrangements herein described, admits of considerable modification without departing from the nature and spirit of my invention. Therefore, I do not wish to be limited to the construction and arrangement shown.
What I claim as my invention and desire to secure by Letters Patent is:
1. A freight car comprising a body having a plurality of seats for unit boxes and a plurality of unit boxes removably mounted on said seats, said unit boxes having horizontally movable devices on the lower portion thereof adapted to engage keepers mounted adjacent thereto on the car body to prevent the tilting of said unitfiboxes on said car body 2. A freight car comprising a body having a plurality of seats for unit boxes and a plurality of interchangeable unit boxes removably mounted on said seats, keepers mounted on said car body adjacent to the respective seats thereon, and horizontally movable pins on the lower portion of said unit boxes adapted to cooperate with the respective keepers to hold said unit boxes on said car body against upward movement thereof.
'3. A freight car comprising a body having a seat adapted to receive interchangeable unit boxes, and separable locking devices comprising a horizontally movable member adjacent to said seat for preventing the tilting of a unit box on said seat.
