Patented Nov. 24, 1931 I UNITED STATES PATENT OFFICE JOSEPH A. TREMBLAY AND JOSEPH 0. DUHOULIN, Ol' DOLBEAU, QUEBEC, CANADA.

j rncxnre Davrcn Application nled February 7, 1930. Serial No. 426,680.

The present invention relates to improvements in packing devices and has for its principal object to provide a device designed particularly for packing in a compact mass .5 paper rolls and similar articles during transit in railroad freight cars or other vehicles.

A further object of the inventlon 1s the provision of a packing device generally'ln the form' of a resilient longitudinally extensible jack disposed to firmly press paper rolls and the like in compact arrangement4 part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a fragmentary top plan view illustrating the application of the packing device in compactly massing paper rolls in a freight car,

Figure 2 is a perspective view of one of the assembled packmg jacks,

Figure 3 is a side elevational view, partly in section, showing several of the component elements in separated positions, and

Figure 4 is an enlarged fragmentary section taken on the line 4--4 of Figure 2.

Referring to the drawings, wherein for the purpose of illustration -is shown a preferred embodiment of the inventiomthe numeral 10 generally designates a fragmentary section of a railroad freight car equipped with the usual side doors 11 and carrying a plurality.

of rolls of paper 12. As is wellknown to those familiar with the shipment of paper rolls, it is advisable to secure, in some manner, the rolls disposed adjacent the car doors, inasmuch as the movement of the car will result in transverse shifting ofthe rolls and consequent injury to the paper and the car structure. y

The packing device or jack comprising the subject matter of the present invention is dev vised for the purpose of resilientlyengag-- ingand retaining in a compact mass the paper rolls durin transit, particularly the rolls disposed adjacent the car doors, inasmuch as these must be retained in position spaced from the doors-to permit convenient opening thereof. The device embodies an article engaging head comprising an elongated plate 15 having a longitudinal arcuate curvature conforming to the peripheral curvature of a roll of paper. The outer side of the plate 15 Acontacts with a pair of elongatedl pivot bearings 16 having journaled transversely therethrough a pivot pin 17 The pin 17 extends through an aperture in the enlarged end 18v of an outwardly extending rod 19, the opposed end portion of therod being exterorly screw threaded to receive thereon a nut 20. A

At the intermediate portion of the device is provided a turnbuckle loop 21 provided with longitudinally extending sleeves 22 and 23 at the ends thereof. The sleeve 23 is disposed to slidably` receive therethrough the threaded end portion of the rod 19, while the opposed sleeve 22 is interiorly threaded for engagement with a longitudinally extending ad usting screw 24.

ositioned about thel rod/19 between the, bearings 16 and the turnbuckle sleeve 23 is a coiled compression spring 25 compressed between a pair of washers 26 and tending to resiliently lextend the turnbuckle from the head plate 15, the resilient extensionjbetween` these members being limited by the adju-stlablenut 20. l 4

Thev outer extremity of the adjusting screw 24 is formed with an enlarged flathead 27 provided with an aperture through which -is extended a pivot pin 28 journaled in a pair of apertured complementary bearings 29. The outer ends of the bearings 29 are provided with V-shaped notches adapted to receive therein an angular bracket plate 30 disposed to be fitted against lthe jamb of a l box car door frame.

As shown to advantage in Fi ures 2 and y3, the interior portionsiof the earings 16 and 29 are'form'ed ywitlrla-n arcuateifseries-ofv apertures 31 disposedjin're istration 'fwith similar apertures 32 in the jenl arged portions of the rod llfandv adjusting screw 24 respectively. :A cotter ypin 33' -is extended through the complementary apertured members at each end to lock' thel same ina suitably adjusted position. Thus, the pivotpin bear ings 16 may be adj usted and lockedto extend at various angles of inclination with respect to the rod 16, while the bearings 29 may be similarly rotatably adjusted with respect to the adjusting screw 24.

y In applying the packing devices or jacks to a shipment of rolls of paper transported in a box car, four of the jacks are placed with the angular plate heads 30 positioned against the'jambs of the door frames, the intermediate stem formin elements being disposed at an oblique ang e and the-curved plate heads 15 positioned against paper rolls disposed inwardly of the car doors, as shown to advantage in Figure 1. A suitable longitudinal adjustment of the jacks is obtained y an initial adjustment of the nut 2O in each jack and by subsequently rotating the turn buckle loop 21 so that the jacks will firmly press against the rolls to retain the same in a compact mass in the car. but will be resiliently yieldable to obviate injury tothe rolls. Thus, the rolls will be held in a closely packed yieldablewdisposition spaced from the doors of the car so as to permit convenient opening of the latter when the car reaches its place of destination. By thus bracing the rolls, both the paper and the box car struc- 'ture is protected so as to reduce the injury to both during transit to a minimum.

It is to be understood that the form or: our invention herein shown and described 1s to be taken as a preferred example of the same,`

and that Various changes as to the shape, size, and arrangement of parts may be resorted to without departing from theY s irit of the invention or the scope of the su joined claims. Having thus described: our invention, We claim: y

l. A device of the character described comprising an article engaging head, a rod extending transversely from the said head, a screw spaced fromv and arranged in longitudinal alignment with the rod, adjustable means connecting the said scrrewand rod, a support engaging head connected with the outer end of the adjusting screw and resilient means on the rod tending to force the heads apart. n

2. A packing device comprising an article engaging head, a rod having one end disposed to contact with the said head. a turnbuckle loop having one endslidab'ly fitted upon the said rod, a spring disposed between said turnbuckle and the outer end of the rod tending to urge the heads outwardly, an adjusting screw threadedly connected with the opposed end of the turnbuckle,l and a support engaging head associated with the outer end of the adjusting screw.

3. In a packing device, an larticle engaging head, a pair of pivot bearings disposed to contact with the said article engaging head, a rod-having its outer' end pivotally connected with the said bearings, a turnbuckle loopl having a sleeve on one end slidably fitted over the outer end portion of the rod, a coiled coin pression spring ositioned about the rod tending to force t e turnbuckle loop at a remote position from the rod bearings, an adjusting screw threadedly connected with a sleeve in the opposed end of the turnbuckle Y loop, apair of bearings pivotally connected insidethe car for the best position to economize space and articles, to be packed, disposed up to the outer edge othe car floor, between the doors of the. car. f

` In witness whereof We have' hereunto set our hands.
