July 25, 1933- J. w. SCHADE METHOD OF REMOVING ARTICLES FROM PACKING CASES Filed March 14, 1930 Patented July 25, 1933 UNETEEE ea critics JAMES W. SCHADE, OF AKRON, OHIO, ASSIGNOR TO THE B. F. GOODBICI-I COMPANY, NEW YORK, N. Y A CORPORATION OF NEW YORK METHOD OF REMOVING ARTICLES FROM. PACKING CASES Application filed March 14, 1930; Serial No. 435,977.
This invention relates to methods of removing articles from packing cases, and more especially it relates to procedure for removing articles which adhere to the cases in which they are enclosed. V
The invention is of especial value for re moving bales of crude rubber from the light wooden cases or crates in which they are usually enclosed during transit, and to which one or more of their faces frequently tightly adhere. The adhesion of the rubber to the wood is so strong that in the removal of the bales from the cases by the methods heretofore employed, small portions of the wooden crates remain attached to the bales and are very diflicult to remove, requiring laborious hand labor with resulting increased cost.
The chief objects of this invention are to provide an improved method of removing articles from packing cases which will effect relatively clean and substantially complete separation of the articles and cases notwithstanding previous adhesion; and to provide a method of unpacking which will save time and labor.
Cf the accompanying drawing:
Fig. 1 is an elevation of apparatus adapted for the practice of my improved method, and the work therein, at the initial stage of operation.
' Fig. 2 is aperspective view of the work at the final stage of operation.
Referring to Fig. 1 of the drawing, 10 is the base casting, and 11 the verticallymovable ram of a hydraulic press, and 12 is a pipe connection for conducting pressure fluid'to the cylinder of the press and for draining it therefrom. Rising from opposite sides of the base casting 10 are posts 13, 13, which support a stationary cross-head 14: upon their upper ends. The ram 11 is provided with a head 15 which is formed in its top face with a eri-lateral recess 16, the latter being so disposed as to receive one corner of a case or crate 17, the ram head then supporting said crate sothat its diagonally opposite corner 18 is uppermost and in vertical alignment with the corner within the recess 16. The cross-head 1a is formed with a recess 19'so positioned as to receive said opposite corner of the case when the ram is raised.
The case 17 contains a bale of crude rubber 20 which usually consists of a solid block or layers. of crepe or sheet rubber, as shown, the bale substantially filling the crate and frequently adhering to the sides thereof. The easel? usually has its corners bound with metal strips 21, which strips need not be re moved or cut before the crate is mounted in the press;
In the practice of my invention with the illustrative apparatus described, the case 17 V with the bale 20 of crude rubber therein is mounted upon the ram-head 15 in the manner shown in Fig. 1, and pressure fluid admitted to the press cylinder to raise the ram 11, the upper corner 18 of the crate thereby being carried into the recess 19 in the crosshead 14 which restrains further movement of said corner.
As the ram 11 continues its upward course the case 17 is 'subyectedto' pressure which is diagonal with relation to its several sides, and thus produces a torque which loosens the corner fastenings 21 of the case. Said torque also effects relative movement between the case-walls and the bale of rubber in the crate, which movement is in the plane of the casewalls so that any adhesion of the bale to the latter is broken by a shearing action which leaves little or no splinters of wood adhering to the bale.
In addition to its action upon the case 17, the compressive force of therising ram is transmitted to the bale of crude rubber 20 therein, with the result that. the bale is d-e' formed, the sides of the bale being bulged.
-The bulging sides of the bale press against The ram ll is then lowered and the work removed from the press, at-which time the work has an appearance somewhat as illustrated in Fig. 2. The sides of the case 17 are loosened from the bale20, and are either separated from'each other or fractured, so that complete removal of the bale from the case is easily and quickly accomplished. The natural resilience of the crude rubber restores it substantially to its normal shape after re moval of the deforming pressure, so that storage and subsequent treatment of the bale may be effected in the usual manner.
The invention may be modified within the scope of the appended claims, as I do not limit my claims wholly to the exact procedure described. 1
I claim:
1. The method ofremoving an adhesive resilient non-compressible article from a packing case completely enclosing the same in close engagement therewith which comprises applying to the case a compressive force which is diagonally directed with relation to its sides.
2. The method of'removing an adhesive resilient non-compressible article from a prismatic container completely enclosing the same in close engagement therewith which comprises subjecting the walls of the container to forces acting along the-planes of its faces and to an outwardly directed expansive force from the interior of the container.
3. The method of removing a resilient noncompressible article from a container bounded by planes completely enclosing the same in close engagement with the articles which comprises applying compressive force to diagonally opposite corners of the con-,
tainer and the article therein.
4. The method of removing a resilient noncompressible article from a polyhedral packing case completely enclosing the same in close engagement therewith which comprises distorting the case by pressure applied externally thereto at an edge thereof in a direction acute to an adjacent side and thereby effecting such distortion of the article as progressive to separate the article fromthe sides of the case.
5. The method of removing a resilient noncompressible article froma polyhedral packing case completely enclosing the same in adhesive engagement therewith which comprises distorting the case by pressure applied from without to an edge thereof in a direc-.
tion acute to any side adjacent thereto and thereby weakening its joints and simultaneously effecting such distortion of the article as to destroy adhesion between the article and the case. 7 v
6. The method of removing a resilient noncompressible article from a polyhedral packing case completely enclosing the same in close engagement therewith which comprises distorting the case by pressure applied to an edge thereof from without in a direction angularly acute to at least one of its adjacent sides and thereby so weakening its joints and simultaneously effecting such distortion of the article as to destroy adhesion between the article and the case.
