' cradle adapted for use with the usual type of railway fiat car. 7

Cars especially designed for the carriage of tanks such'as are used in the transportation of chlorine and the like may be provided with built in cradles forming a per- .manent part of the car.

Such cars are entirely satisfactory, and

' are economic in operation, when shipments are made at intervals, recurring with substantial regularity, and in car-load lots. When, however, the shipments are at uncertain periods, the cars are not always available, and if the shipments are delayed for any reason, the cars, which are suitable for the transportation of a particular character of goods only, will be idle. Furthermore, when shipments must be made of less than carload lots, the full capacity of the car cannot be utilized, since the portion of the car notoccupied by the tanks is not ble of utilization for other freight. Since the cradles in this type of car are builtin, and form a permanent part of the car, they are not adapted for emergency use with existing cars, nor for application to such carswithout material changes in the car.

The object of the present invention is to provide a cradle, adapted to be mounted on the usual type of car, either permanently or temporarily, to fit the car tocarry a full or partial load of tanks, and without material change in the car itself.

each bolt above the washer, and it will be Figure 5 isa partial end view showing an alternate form of clamping mechanism,

Figure 6 is a partial side view of a car with a cradle in lace. In the e'mbo iment of the invention shown in Figures 1 to 4, the improvedcradle comprises a pair of similarbeams 1, of angle material in the-present instance, ar ranged in spaced parallel relation, and rigidly connected together, b means of crossbars 2, and crossbraces 3. 1e bars 2 are arranged at the ends of the beams, and the braces are arranged in X shape intermediate the ends. Thus there is provided a rigid framework for supporting the nks, and capable of being mounted upon a car. The upper edges of depressed seats 4, shaped to fit the periphery of a tank 5, of the character which they are designed to support, and the seats of onebeam register with those of the other, as clearly shown in Figure 1. At each seat,

the beams 1 are formed into each beam has an' inwardly extending flange as shown, curved on the same are as the seat, to strengthen and relnforce the mate- 'rial of the beam.

Suitable means s provided for clamping the tanks to the seats. In Figure 1 the'said means is in the form 'ofba'nds 6 which are curved longitudinally to fit the peripheries of the tanks which they are designed to engage, and at'each end each band has an upwardly bent lug 7 for a purpose to be presently described. The bands are of a length substantially equal to one-third the perimeter of the tank, and the adjacent endsof the bands at each side are connected to the cradle by.

means of a bolt 8. Each of these bolts passes through a portion of the beam between two adjacentseats, and upwardly between the seats as shown in Figure 2. Awasher 9 is arranged on eachbolt, above the ends of the bands 6, and each washer has depressions I 10 in itsunderside, at opposite sldes of the washer A nut 11 is threaded on to which the adj aoent ends of the adjacent bands are hinged- The bolts 7 8 have their heads for receiving the upturned lugs 7 do\vnwardly,while with the bolts 12 the cross-head 13 of the bolt is the head, and the nuts 15 corresponding to the nuts 11 of the bolts 18 are below the portion of the beam through which the bolt passes. The improved cradle sections may be of any desired length, for containing any desired number of tanks. In the present instance the sections are of a length to support four tanks.

Referring to figure 1, it' will be seen that the tanks are of greater length than the width of the framework of the cradle, so that the ends. of the tanks extend beyond the frame ateach' side thereof. I

If desired, the alternate form of clamping arrangement shown in Figure 5 may be used. This clamp comprises chain sections 16 and 17. Each chain section has at oncend an eye bolt 18 en aging a portion of the frame of the cradle indicated at 19, and the free ends of the chains are connected by a hook lever 20. This lever is pivoted to the free end of the, chain 16, and the hook engages the free end of the chain 17. A suitable clamp 21 is provided for holding the lever extending substantially parallel with the link to which it is pivoted, when the chains are connected. It will be understood that'a pair of chains is provided for each end of each tank. The two chainsof each pair are connected by engaging the'hook of the lever 20 with the last link of the chain 17, the lever being swung far enough to the left of Figure 5 to permit such engagement. The lever 1s then swung to the r ght and engaged with p the clamp 21.

In Figure 6 there is shown a flat car 22, with cradle in place. lit will be understood that the cradle sections may be of any desired length, preferably of such length that a multiple of the sections will fill a car. The

sections may be anchoredto the car in any suitable manner, and for this purpose openings 23 are provided in the beams l, for engagement by bolts, rivets or the like. The full capacity of the car may be utilized with this t pe of cradle, or only a part, as may be foun' advisable. Either of the clamping mechanisms may be used for clamping the tanks to the cradle.

It will thus be seen that the present invention provides a' cradle which may readily be mounted, either permanently or temporarily,

upon the usual type of car. This cradle is in itself readily portable and forms a convenient unit with attached tanks for-handling purposes. Material change in the car is unnecessary. This cradle can be readily at tached or detached and is adapted to be loaded upon a car or removed" therefrom with its full load of tanks in place. ll claim:
