The vertical depending arms 36 and 37 of each safety unit 33, 34 and 35 are provided at their lower ends withthesubstantially U-shaped metal 3 caps 42 and 43 respectively whichflt about'the said arms and are nailed thereto as indicated at 44. Received between the lower ends of each.

In other words, thepivot point 46 is offset with respect to the longitudinalcenter' of the dog or catch inember45, with the result that the longer forward end 47 thereof naturally tends to overbalance the shorter rear end 48. P'ositionedb'etween the vertical arms '36 and 37 of each'safety unit 34' and 35 and beneath the bracing, strip'39is a relatively hard wooden block 49 secured in place by bolts or the like 50 and 'having' a lower bevelled edge 51 against which'the end 4301? dog 451s adapted to abut so as to maintain the said dog in the 35. 5 against which theglass sheet is adapted to abut proper inclined position. The forward end edge of each dog 45 is preferably bevelled as at 52 to provide a substantially vertical face when the said dog is'in'its normally inclined position and should it fall forwardly;

, In the loading of relatively large sheets of glass within a freight car, it is customary to stack securethem firmly in place for, shipping by.

a pile of sheets against each side of thecar and meansfof suitable. ropes or metal bands which are passed horizontally in front or each stack 7 of sheetsand fastened to theadjacent sidewall the glass sheets piled against-the other side ofv -of the car. More specificallyt'it is customary, in packing the glass sheets within the freight car, to

firstjack up one side of the car so that'the side walls thereof are slightly inclined. The .glass sheets are then stacked one at a time against the words, against" that side which is not jacked up.

lower" inclined sidewall of the car 'or; in other After the desired pile of sheets has been thus stackedg they are firmly secured in'place for shipping inthe manner above described. The

opposite side of the car is then jacked up and the car in the same manner. Thus, there is provided'a stack of sheets at each side of the car, with a spaceor aisle therebetween, such aisle being necessary in-ordertopermit access to the glass sheets when they are to b'e unpacked. It is also the'usual practice'to pla'ceiafslieet of paper between each'sheet of glass so that the glass sheets do not come in direct contact. with oneanother.

Workmen have been seriously injured in the past asTaresultof the glasssheets falling forwardly upon'them duringthe stacking of ,the' said sheets in place. Forinstance, it not infrequently; hap; pens. that a workman, in pulling out two or three sheets .of glassinorder to placethe sheetsfof paper therebetween, will have the suction between the sheets pull the balance of the pile of sheets forwardly upon him, resulting not only in serious injury tohi's." person, but also inthe breakage of the glass. The present inventionhas been especially designed to safeguard the workmen engaged in loading the car by preventing the glass sheets from falling forwardly upon them, as a result of which the liability of the workmen being injured during the packing of the car will be greatly lessened. s

'In the use of the present invention. one or any suitable number ofsafety devices B may be employed, and these devices are secured within the freight car A above the glass sheets 10 in the manner above described. That is to sayythe transverse supporting structure 17 of each safety device is secured in position within the car by means of. the bolts 29 and 30 which are caused to engage and bite into' the side walls of'said car. The supporting structure 17. is arranged at such a height within the car so that thelower ends of the pivoteddogs 45 will project slightly below the upper edges .of the glass sheets. The dogs 45 'of the safety or sheet retaining units 33, 34 and 35at each side of the longitudinal center, of the supporting structure 1'7 are mounted so that the lower ends thereof project toward the respectiveside wall of the car. Therefore, as each sheet of glass is placed in position against the side wall of the car, the upper edge of the sheet engaging the lower. ends" or the dogs 45 will cause the said dogs to be swung upwardly to a substantially horizontal position as indicated by thebroken; lines in. Fig. 4 to permit the stacking of the glasssheets' in place. Aftereach' sheet has been slipped beneath the dogs, the said dogs will again fall downwardly into an inclined position by gravity, and the saiddogs will be maintained in. such inclined position and prevented from swinging in the opposite direction by means of the. wooden-blocksv 49. As a consequence should one of the glass sheets'fall forwardly as shown at 10a in Fig. 1, it will engage the first inclined dog. 45 and be prevented thereby'from falling forwardly upon andinjuring the workmen er gageclv in stacking the sheets within the car."

In the event only a few sheets of glass have been placed in position, and should they fall forwardly, they will be caught by the dog 45 of the" =first-safety unit 33, whereas if a greater number ofsheets; have been stacked in place, they will be caught by the dog 45 of the second safety unit-.34 orby theidog of thethirdsafety'unit' 35.

After the requisite number ofv sheets have been stacked against each side of the ca'r and secured in position in the manner above described, the

:safety devices B are removed. Thenumber of safety-devices employed will depend upon the width of the glass sheets being packed, with two.

or more being ordinarily used, while the height at which the safety devicesare positioned within the car will depend upon. the height of the glass sheets'being packed. As brought out above,

the improved safety devices herein provided are not restricted to use in the packing of glass sheets but, on the contrary, may also be utilized in the, packing of other fiat sheets or plates. It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same;
