FRUIT-CAR BRACE.

Application filed lq'ovember 29, 1927. SerialNo. 236,455.

This invention relatesto devices for bracing boxes of fruit as stacked in refrigerator cars for shipment, to prevent the boxes from shifting with the jolting and vibration incident to the moving of the car.

At present such essentialbracing is doneby means of wood staging of a temporary nature which is erected 1n place every time the car is loaded and which must be wrecked when it is desired to unload the car. This is obviously a crude arrangement which consumes considerable t me to carry out, entails a costly use of material which once used is discarded, and which is frequently unsatisfactory or insuflicient due to faulty erection,

lack of rigid contact with the boxes, or insuf-,

ficient strength. V

The principal objects of my invention are to provide a bracestructure for the purpose which is of a permanent nature adapted tobe permanently mounted in the car; one which is provided with means for enabling the braces to be easily moved into, firm pressing or bearing engagement with the boxes; and one having means for enabling the braces to he quickly and easily moved and held out of the way in the car while loading or unloading operations are being carried out or whenever it is desired to use the car for merchandise not requiring the use of the braces. V

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusalof the following specification and-claims.

In the drawings similar characters of reference indicate corresponding parts in the several views: e

Fig. 1 is a side elevation of my brace structure as applied to a car and boxes stacked therein. y i

Fig. 2 is a frontelevation of one of the brace members as in operating position.

'Fig. 3 is an enlarged sectional elevation of a presser device for engagement with the material, which are adapted to rest on tho sides of the car, taken on the line 3-3 of frames 1, of suitable rigid construction andwooden rack-bars 2, which removably rest on the floor 2 of a refrigerator car as usual.

These frames extend practically the full width betweenthe sides 3 of the car but termlnate a considerable distance short of the roof 4, since fruit boxes. arenot ordinarily stacked very high when being shipped in a car.

The frames are adapted to set in "longitudt I nally spaced relationand their opposed faces are perfectly flat so that they will evenly engage the ends of all boxes 5 of both longitudinally spaced stacks. On their adjacent faces, the frames are provided witlia plurality of vertically spaced lugs 6 arranged in transversely spaced sets to pivotally support the ends of rigid vertical bows 7. These bows may swing to lie. alongside the frames so as to be then out of the way or to a position at right angles to the frame. When in the latter position, lugs 8 and 8.on the jaws and frames respectively register with each other to receive removable pins 9to then hold the bows from swinging out of position.

The bows are tapped centrally between their ends to receive lack screws 10. The bows are disposed on tie oppositeframcs so that corresponding screws of adjacent pair of bows lie in substantially common axial alinement and the headsll and 1 1 of the screws are then adapted tov abut against each other. The head 11 has asocket 12 and the head 11 has a ball 12 to engagethe socket as shown in Figure 5. The adjacent ends of the heads have radially projecting lugs 13 thereon adapted to register and receive a re-I movable pin 14 therethrough. The heads also have suitable orifices theretlirough to-receive a a turning bar or the like. The ball and socket connections between the heads I allow the screws to be slightly out of line without interfering with their operation. The screw threads are all cut in1the same direction so that when the screws are abutted and are directions, the frames willv be ;moved away from each other and forcedinto pressing engagement with the fruit boxes. After such pressing engagement is had, the screws are turned if necessary until the lugs '13 register frame to be advanced the same distance as the other is retracted, the space between the] frames is not altered and they will not loosen turned independently of each other in certain up relative to the boxes. The use of the bows distributes the strains from the screws to vertically spaced points in the frames so that a more even pressure is obtained than would be the case if the screws bore directly against the frames.

' To maintain the frames against possible lateral movement in the car, pads to engage the sides of the car are slidably mounted in the sides of theframe for horizontal movement. These pads are formed with plates 16 bearing against the faces of the frames, which plates are frictionally engaged with the frames so as to prevent their shift by clamp ing plates 17' mounted in connection therewith. This arrangement is preferably the same as is commonly used to hold the ordinar wood-working plane blades.

Since the frames may have to be placed at somewhat widely varying distances from each other, 'ack screws of different lengths are provided for use with the bows and such extra sets of screws as are not used at any time are kept in holders 18 mounted on the frames.

To press the frames firmly against the floor, I provide vertical post 19 which pro- 'jects upwardly from said frames at trans-i versly spaced intervals. These posts have threaded engagement with bosses 20 on the frames and at their upper ends said posts have enlarged heads 21 for engagement with the roof 4. The posts are slidable in the heads and compression springs 22 are mounted between the posts and heads to provide yield.- inr connection therebetween (see Fig. 1). W en not in use the posts are screwed down so that the threaded portion is clear of the bosses 20, and the posts are then slidably re ceived in sockets 23 provided on the frames at vertically spaced intervals.

It will, therefore, be seen that by these various features the frames are maintained in pressing engagement with the fruit boxes and arealso held in immovable relation to the sides and top of the car so that there is no chance for the frames to shift in any direcopposite ends of the car. These rails also tion. 7

To raise and hold the frames out of the way when not in use, I provide the following structure: Depending from and secured to roof 4 and extending lengthwise of the car above the frames centrallyof their width is a railv 24 which slidably supports a chain block 25. Disposed adjacent the sides of the car and also depending from and supported by-the roof are other rails '26 which extend lengthwise of the car a certain distance from a longitudinally overlapping relationship with the ends of the central rail towards the slope downwardly toward their adjacent endssomewhat. Hooks 27 are secured to and de nd from the adjacent ends of the side rails, whileslidable lengthwise on said rails are hook members 28. The frames are pro- 29 of one frame and the frame is raised until adjacent the roof, when the upper side books; 30 are then engaged with the movable hooks 28. The chain block is then disengaged from. the upper hook 29 and engaged with the The lower end of the frame is then swung up the upper end supported by lower one.

the hooks 28 at the same time moving toward the two ends of the side rails. The frame then gradually assumes a horizontal position and when its lower end is raised to adjacent the roof, the hooks 31 are engaged with the fixed hooks 27. This frame is then held in a horizontal position just under the roof where it is out of the way of loading orunloading operations. When one frame is thus in place, the other frame is manipulated in the same manner. When it is desired to lower the frames, the operations as above outlined are carried out in the reverse order as will be evident. The sloping down of the rails 26 toward their adjacent ends insuresthat the hooks 27 and 28 without being suspended from chains, etc., will be low enough so as to be in position toengage the frame eyes 30 when the frame is raised as high as possible by the chain-block, without the operator then having to manually lift the frame further.

The sloping rails also cause the frames when supported thereby to lie at a slope, which will prevent theuprights 19 from possibly working out of place.

From the foregoing description it will be readily seen that I have roduced such a device as substantially fu fills the objects of the invention, as set forth herein.

\Vhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined bythe appended claims.
