PLACARD'SUPPORT FOR TANK CARS..

Application filed December 15 1927. Serial N0. 240, 2 80.

This invention relates to devicesfor supporting placards upon cars, and particularly for supporting placards upon tank cars showing whether or not the tank car is filled, or in other words contains inflammable material, and while the, invention is particularly designed for use with tank cars transporting gasoline and other highly inflammable and volatile liquids, we do not wish'tozbe limited to this use as the same device might be used upon cars for supporting placards for other purposes. I

The general object of the present invention is to provide a placard supporting member and a fixed shield, and providemeans whereby the placard supporting member may be disposed in position behind said shield and entirely obscured thereby as, for instance, when the car does not contain inflammable material, or whereby the placard may be shifted into a position in front ofsaid shield, thus entirely obscuring the shield but displaying the placard stating that the car does carry inflammable or explosive material.

A further object is to provide meanswhereby the first named placard may be locked in either of its adjusted positions, and provide means whereby theplacard may be concealed in this position so as to prevent any unauthorized tampering with the placard.

A further object is to provide a device of this character including a support adapted to be attached to the running board of a tank car, provide a fixed shield mounted upon the support, and provide a movable-placard sup: port rotatably shiftable from a position occulted by the shield to a retracted position and then movable into a position in advance of the shield and'then rotated to a position directly in front of the shield. 1 7

Our invention is illustrated in the accompanying drawings, wherein 2+- Figure 1 is a front elevation of a placard support constructed in accordance with our invention and displaying fixed placard or shield; a

Figure 2 is a side elevation: of the struc ture shown in Figure 1;

Figure 3 is a rear elcvationot the structure shown in Figures 1 and 2;

Figure 4 is a fragmentary section showing the connection of the rock shaft to the placard-supporting arm;

Figure 5 is a front elevation of the structure shown in Figure 1 but with the removplacard able placard disposed in front of the fixed Figure 6 is a like view to Figure 2 but showing a different position for the movable placard; e i i shown in Figure 6; g

F lgure 8 is a fragmentary detail elevation Figure 7 is a rear view ofthe structure of the lower endhof the placard -supporting arm 19."

Referring to these drawings, it wlill be seen that 10 designates a supporting bracket which is somewhat U-shaped'in form and has its arms depending. one of these arms 11 .is relatively short. The other arm 12 is relatively longer than the arm' 11 and at its lower end is inwardly bent, as at 13, and then upwardly extended, as at'l l. ,This bracket 10 has riveted to it orotherwise attached to it the plates 15 which are designed to fit against the bottom of: the running board 01 a tank car and be attached thereto by riveting, bolting or any othersuit'able means. I

Riveted upon the upwardly extending portion 14 is a laterally and upwardly curved extension 16 which extends upward nearly to the level of the top of the bracket and then extends laterally as at 17. This extension is welded to a plate 18 Whichforms part of an.

upwardlyextending supporting bar 19. The upper end of the extension 16 and the plate 18 are both formed with arelatively large aperture 20 extending through these two members. Riveted to the vertically extending bar 19 is the shield 21' which is prefers ably square in form,'though-not necessarily limited to this form, and is disposed with two corners of the square in .a vertical line. It will be seen that the bar 19 is rigidly engaged with the member 16which forms an extension of a portion 14: of the bracket, the extension being riveted to this portion 14 by the rivets or bolts 22. l i

Oscillatably mountedinthe portions 11 i shield 21 and which is riveted to the arm.

V I the Opposite side of the Of course, we do not wish to be limited to the material of the "shield or of the placard. The arm 27 below the shield carries the inwardly; projecting pin 29 which, when the arm 27. confronts the arm or bar 19, will enter the aperture 20 previously referred to and acts as a locking bolt.

Attached to the rear or inner face of the portion 12 of the bracket 10' is a downwardly,

laterally and rearwardly curved supporting rest 31 which extends downward to a point slightly below the pivotal center for the arm 27 Extending through the portion 12 of 'of a coiled spring 33 which surroundsthe shaft 23' and bears at one end against the portion 12 of the bracket 1.0 and atthe other end against awasher 34, this washer being heldin place by a cotter pin 35. z The shaft 23 is formed with two apertures 36 and 37 and a pin 38 is adapted to be disposed in either of these apertures.

In the use of this device,assuming that the placard 28 is disposed behind'the shield 21 and 'that'it is desired to display the placard 28, thenthe'pin'88 is removed and the shaft 23, pushed inward sufficiently far to carry the pin 29 then be rocked in a counter-clockwise direc- V r tionto' swing the arm 27; and the placard 28 downward until the arm rests upon the support 31. At this time the placard 28'has moved entirely beyond the shield 21 and the shaft may be pulled forward or allowed to move forward under the action of the spring 33. When it is moved sufficiently forward, 7

the shaft is'again rotated, this time in a clockwise direction, which carries the placard 28 up in front of the shield 21, as shown" inFigure 2.: The arm 27. cannot move for ward any faster than is permitted by'the curved supportBl, but when the arm 27 has reached a vertical position the pin 29 will be directly opposite an opening 20 formed in the portionl2 of the bracket 10 and the pin 29will enter this opening 20 and again lock the placard in a vertical position, this time 7 with the placard entirely obscuring the shield. lVhen this has been accomplished the pin 38 may be then" again inserted through th'eiopening 36, which will prevent inward movement of the shaft, and thus pregvent the placard supportingarm from being removed from its locked position. Preferably the portion'll of the bracketis formed with an aperture39, as is theend of the pin 38, through whicha sealing wire may be 7 out of locking engagement with the aperture 20 in bar 19. lhe shaft may passed so as to lock the pin 38 inplace against accidental removal.

It will be understood that while we have referred to the part 21 as a shield and the part 28 as a placard that this is merely to I differentiate between these two elements but that, as a matter of fact, the part 21 will also constitute a placard or sign and will preferably have thereon words denoting that the car is empty, while the placard 28 will have thereon words denoting that the car isfull. These signs might be, reversed, however. The point is that when the member 28 is behind the member 21, the member 21 will be displayed whether this member 21be en tirely blank upon its face or contain signs or symbols, and that when the member 28 is shifted in front of the member 21, the member 21 will be occulted and if there are any signs or symbols upon the member 28 these will be displayed;

It will be seen that we'have provided very simple means whereby one or the other of two placards may be displayed and locked in this display position, that thisplaoard apparatus may be readily operatedfrom the side of the car, and that the placard device fully complies with the law regarding the placarding of tank cars or cars carrying'explosive materials. IWhile preferably the elements 21 and 28 will be made of metal as, for instance, thin sheet metal which is flanged at its margins, we do not wish to be limited to this. The signs, symbols or other directions may be painted upon these elements or printed matter may be pasted.

thereon l/Vhile we'have illustrated certain details of construction. and arrangement of parts which have been found to be particularly efiective for the purpose intended, we do not wish to be limited thereto as many changes might be made therein without departing from the spirit thereof as defined in the appended claims.
