Sept. 1l, 1934. R CLAPP FREIGHT CONTAINER Original Filed Oct. 8. 1951 INVENTOR v @WW @ctober 8, 1931.. This 1933, Serial No. 692,759
application Uctober 9,
19 laims. v (El. 289-44) This invention relates to shipping containers, and more particularly to a container or receptacle for shipping less'than car load lots. This application is a continuation of my application Serial No. 567,719, filed October 8, 1931.
y An object of this invention is to provide a container or packing member which is adapted to be placed in a freight car or other carrie-r, the .device receiving articles for shipment which are of a size and quantity less than suilicient to ll a freight car.
Another object of this invention is to provide a shipping device of this kind which is so constructed that it will protect the articles placed therein against damage during the shipment in a carrier, the device also including means whereby it may be readily moved on a at surface such as out of the carrier and onto a platform or other flat surface.
A further object of this invention is to provide a device of this kind which can be moved by a crane or other lifting device and which, when placed in approximately the desired 'position, may be readily shifted so that other articles 25 may be placed in the carrier in close proximity to the device.
A still further object of this invention is to provide a shipping member of this kind which is relatively light in weight but having sufficient rigidity to protect the articles positioned therein so that the container will not be damagedduring the movement of the carrier.
The above and various other objects andadvantages of this invention-will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein- Figure 1 is a detail top plan View of a device constructed according to the preferred embodiment, of this invention, having the top removed therefrom, and
Figure 2 is a longitudinal section taken on the line 2-2 of Figure 1.
Referring to thev drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral designates generally a shipping receptacle or box having a bottom 11, side Walls 12 and end walls 13 and 14, the wall 14 constituting the front end of the receptacle. The bottom, side and end walls of this device are preferably constructed of metal which may be suitably reinforced so that a relatively.rigid box-like construction will be provided wherein various are ticles for shipment may be positioned, these articles being in quantity less than a car load lot.
A top 15, which has marginal depending anges 16, is secured to the side walls 12 and 99 the end walls 13 and 14, and a pair of lifting rings 17 are secured to the top 15 adjacent each end thereof land in substantially the lon-` gitudinal center thereof, these rings 17 being mounted in bearings 18 or the like. In con- 65 tainers of this kind where relatively heavy articles are mounted therein, it is exceedingly difiicult to shift the containers without the use of cranes which engage the loops or ring members 17.
In order to facilitate the shifting or moving of the container 10 either within the carrier or other fiat surfaces, I have provided a plurality of wheels or rollers 19, which are pivotally secured to levers 20, which levers 20 are pivotally 75 or rockably mounted in U-shaped supporting members 21 carried by the bottom 11. These rollers or wheels 19 are provided in opposed pairs and the levers 20 are disposed clearly adjacent each side wall 12. The lower ends of the levers 20 are pivotally mounted in the U-shaped supports 21 by means of a pivotal member 22 or the like. The bottom 11 is provided with slots or openings 23 therethrough, the purpose for which will be hereinafter described.
In order to rock the levers 20, I have provided a bar or shaft 24 which is rotatably mounted in the side walls 12 adjacent the top thereof and closely adjacent one end, the shaft 24 constituting a part of a winch or Winding apparatus and this shaft 24 is held against lateral movement ywith respect to the side walls 12 by means of stop members 25.
An equalizing bar 26 connects the front pair of levers 20, the equalizing bar 26 being mounted 95 in the upper ends of these bars 20 and a chain or flexible member 27 which is trained over the shaft 24 engages a clevis 28 carried by the equalizing bar 26 adjacent the central portion thereof. The front and rear levers 20 of each 100 pair are connected together by means of a tie rod 29 having eyes 30 at each end thereof for engagement with a pin 31 carried by the levers 20.
A turnbuckle member 32 engages the abutting 105 ends of the tie rod 29 so that the front and rear levers 20 may be suitably adjusted for projecting the wheels or rollers 29 through the openings 23 in the bottom `11 for the desired distance. Ereierably, the distance that the rollers 19 will be projected through the bottom is only suilicient to raise the container 10 oif of the oor or fiat surface, so that the rollers or wheels 29 need not be projected outwardly through the bottom for a distance equal to the diameter thereof.
In order to facilitate turning of the shaft 24, one end 33 thereof is preferably formed into a square and a ratchet wheel 34 is secured to the projecting end of the shaft 24. A pawl member 35 is pivotally carried by the adjacent side wall 12 of the container 10 and engages the ratchet 34 so as to hold the shaft 24 against rotation in one direction. A handle or operating member 36 is adapted to removably engage the projecting end 33 of the shaft 24, so that the desired leverage can be applied for turning of this shaft 24.
In practice, the winch construction herein disclosed is such that the wheels 19 will be projected through the bottom 11 for the desired distance, so as to facilitate rolling or shifting of the container 10 by turning the shaft 24 not more than a single turn. A door or closure 37 is hingedly carried by the front wall 14 and a latch member 38, which is mounted on the front end 14, is adapted to engage a keeper 39, so that the container 10 may be locked for protecting the contents thereof against unauthorized removal. The turns of the shaft 24 required to raise the container may vary, depending on the size of the shaft 24 and the degree of projection desired of the wheels 19.
In order to protect the container lifting mech-` anism hereinbefore described, I have provided an inner wall Vconstruction including a screen or web-like member 40, which is secured at each end thereof to angle bars 41 or the like, carried by each end of the container 10. This inner wall construction 40- is disposed in parallel relation to each side wall 12 and in inwardly spaced relation thereto and is of a height such that it will not intefere with the longitudinal movement of the equalizing bar 26 or the flexible member 27. In this manner, the contents of the container 10 will not shift laterally therein to a position where they will interfere with or prevent the movement of the levers 20.
In the use of this device, the articles are adapted to be placed within the container 10 between the inner walls 40 and when the container 10 has been filled to the desired extent, the door or closure member 37 may be sealed or otherwise secured so as to prevent unauthorized removal of the contents of the container 10. This container may then be lifted or shifted by inserting cables or other members in the ring members 17. 1f desired, however, the container 10 may be shifted without the use of the rings 17 by merely turning the shaft 24 through the use of the shaft operating member 36, so as to i rock the wheel carrying levers 20 forwardly and project the wheels 19 through the slots 23 of the bottom 1l. In this position, the container 10 may be shifted or rolled into the carrier and when in the desired position within the carrier,
the shaft 24 may be rotated in the opposite direction so as to permitthe levers 20 to move rearwardly and carry the wheels 19 inwardly of the container and out of engagement with the floor or other at surface.
It will be noted, from the foregoing, that this container 10 will eectively seal the articles therein and protect the articles against damage during the movement of the carrier and that the contents of the container 10 cannot be removed until the door 37 has been unlocked or unsealed. The winch operating lever 36 is preferably forwarded along with the container 10 and if de sired, may be placed' within the container 10 after it has been placed in the carrier in the desiredposition, or it may be otherwise placed in a position where it can be readily used for shifting of the container l0 during the removal of the container from the carrier.
It is, of course, understood that various changes andv modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
