WILLIAM A. WEBSTER, OF GALESBURG, ILLINOIS.

BALING-IRESS ANI) THE LIKE.

Application led December 12, 1913.

To all whom t may concern:

Be it known that I, WILLIAM A. WEBSTER, a citizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Ealing-Presses and the like, of which the following is a specication.

The present invention has reference to certain improvements in the construction of baling presses intended particularly for use in the baling of such material as waste paper form of baling machine in which the sidey walls of the casing extend in a vertical direction and parallel to each other.

found that the friction of the baled material against the inclosing casing is so large lthat it becomes necessary to hinge the casing in order to permit removal of the same from the bale.

One of the features of invention .to

which the present application relates hasV reference to a tapered or gradual enlargement of the casing so that it can be easily lifted off from the bale without the necessity of providing a hinged construction, such as that above mentioned.V

If the paper or other like material be baled in the ordinary manner it will be found that the edges of the successive layers of paper protrude or stick out from the side of the -bale so that portions of the paper become readily detached and the bale will therefore assume a ragged, appearance.

Another object of the present invention is to so construct the press head, and to so relate itl to the inclosing casing,y that as the.

material is compressed the edges of the layers of paper will be bent or curled up into the body of the bale. This will result in the production of a more permanent and pre- Speccation of Letters Patent.

In the: case of such constructions it is frequently- Patented Oct. 31, 1916.

sentable bale, thus improving the quality poses.

`Another object of the invention has reference to the construction of the baling mac hine in such form that substantially the entire volume or body of the casing may he completely filled with the baled material, notwithstanding the fact that in the compressing process the volume of the material is greatly reduced. A It will presently appear that this result can be attained by performing a number of' compressing operations with a single presshead without the necessity of removing the inclosing casing between successive compressing operations. In connection with this feature lof the invention I have also provided a construction such that when the entire bale is completed it can be removed without interference from the screw threads which are used in one embodiment of the invention for the purpose of forcing down the press head.

Another object of the invention hasv reference to the provision of a construction such that after the material has been compressed and the inclosing casing has been removed the necessary tie wires or binders can be readily. placed for the purpose of binding up the bale, and without interference from portions o-r parts of the mechanism which mightotherwise interfere with the readyperformance of this operation.

Other objects and uses will appear from a detailed description of the inventionv which consists in the features lof construction and combinations of parts hereinafter described and claimed. Y In the drawingsLFigur'e l shows a side view of a construction embodying certain features of my invention., a portion of the inclosing casing being broken away to show the press head and sleeve which' are in lowered position corresponding to the first half 0f the baling operation; Fig. 2 shows a side view of the baling machine with the bale completed,- the inclosing casing being removed and the cords being` inserted for tying up the completed bale; Fig. 43 shows a plan view of the lower stationary head; Fig. i'shows a bottom view of the upper press head; and Fig. 5 shows a side elevation of a modified construction of baling machine embodying certain features of the arms 15.

present invention, the inclosing casing being in raised position corresponding to the second half of the baling operation.

The main difference between the construction shown in Figs. 1 to 4 inclusive, and that shown in Fig. 5, is that in the latter figure the inclosing casing is cylindrical in form and is hinged to permit its ready removal, whereas in Fig. 1 the inclosing casing is tapered. Nevertheless, certain features of the invention illustrated in Figs. 1 to 4L inclusive are clearly applicable to and are embodied in the arrangement shown in Fig. 5.

In the arrangement illustrated in the several gures the baling machine comprises a lower stationary head `6 extending upwardly from the central portion of which is a fixed rod or bar 7. rIhe lower head is preferably constructed in the form' of a number of outstanding arms or the like 8, and for purposes of convenience four such arms are illustrated. Near the outer end of eachy of these arms is a lugy or pin 9. An' inclosing casing 10 is adapted to seat on the lower head, and is maintained properly centered by the pins 9. This fact is well illustrated in Fig. 1.

It has been found by experience that in the baling of paper and the like a compression of approximately one-half of the ordinary volume is secured when reasonable pressure is applied. Of course the amount of the compression will be determined, to some extent, upon the amount of pressure which is to be applied. The rod 7 is extended upward a distance somewhat greater than the height of the inclosing casing, this distance depending largely upon the percentage of compression which it is desired to attain. In the arrangements.illustrated the rod is carried up above the inclosing casing an additional distance equal to approximately one-half the height of the inclosing casing. The lower portion of the rod up to approximately the upper edge of the casing is unthreaded and is smooth, to permit the ready removal of the bale as will presently appear. On the other hand, the upper portion 11 of the rod is threaded, the threads preferably being cut into the rod so that their greatest diameter is not larger than the1 diameter of the lower portion of the roc.

A screw handle or the like 12 threads onto the upper portion of the rod and is adapted to force the upper press head 13 down during the pressing operation. This upper press head is conveniently illustrated as comprising a plate having a central portion 14 with a number of radially extending In the particular construction illustrated there are eight of these arms, opposite pairs of them being slightly wider thanV the intermediate ones.

W'hen it is desired to perform a baling operation the casing 1() is first set in place on the lower head, being properly centered by means of the pins 9. The upper press head and the screw handle -are removed, and papers ory other materials to be baled are filled into the casing around the rod until the casing is filled practically to its upper edge. The upper press head is then set into position and allowed to rest on the material. Inasmuch as the threaded portion of the rod does not extend down into the bodyvof the casing it will beseen that the press headcould not be forced down'byyrotation of thev threaded handle unless nsome element were to be inserted between the handle and the press head. For this purpose a sleeve 16 is slipped down over the rod to bear against the press head, and the threaded handle is then threaded onto the upper end of the rod. This sleeve has a length equal to approximately one-half the height of the inclosing casing,^so that as the handle kis threaded down the compression` operation may be carried forward until the material has been reduced to approximately one-half the bulk which it previously occupied and before the threaded handle reaches the lower end of the threads of the rod. If the baling operation were to be stopped at this point the volume of the baled material would be only approximately one-half of the total volume of the inclosing casing. The construction herein disclosed, however, is such that the baling operation mayA be continued for the purpose of ultimately producing a bale of greater volume than that produced during the first operation. By rotating the threaded handle in reverse direction, so as to vthread it up on therod 7, it can be removed. from the rod, and the sleeve 16 may also be removed. The 'upper press head may then be raised away from the upper surface of the previously compressed material. It might be assumed that as soon as pressure were released from the compressed material that the latter would expand and follow up to reoccupy the space which it originally occupied. As a matter of fact, however, upon the releasing of pressure only a slight amount of expansion will follow when the machine is being used in the baling of paper and the like.

After having removed 'the sleeve 16, the threaded handle is rethreaded onto the upper end of the rod. The inclosing casing may then be raised so that its lower portion is substantially in line with or slightly overlaps the upper end ofthe stack of previously compressed material. This will bring the upper end of the casing in lineA with the upper portion of the threads on the rod 7 The casing may then be lled withl an additional volume of material,l after which the upper press head may be forced down to compress this additional volume of material. If this compression also be suflicient to reduce the volume of the newly filled material by one-half the press head will be brought down to a point where the entire body of compressed material occupies a space substantially equal to one volume of the entire casing. Under these conditions the press head will stand substantially in the position illustrated in Fig. 2. It is now desired to tie or bind the completed bale of material. In order to facilitate this operation, notches 17 extend across the upper face of the lower head in both directions, and notches 18 extend across the lower face of the upper press head in both directions. A rod 19 having a hook 20 may be used for drawing a cord or string through these notches so as to encircle the bale from top to bottom, and thereupon the cord may be tied, as indicated in Fig. 2. After the desired number of ties have been effected the upper press head may be removed by unthreading the handle. Thereafter the entire bale may be removed by slipping the same off from the rod 7. This last operation may be easily performed with the present construction by reason of the fact that the lower portion of the rod against which the material presses during the compressing operation is smooth, and by reason of the fact that the threads on the upper portion of the rod are not of greater diameter than the diameter of the smooth portion of the rod.

The raising of the casing 10 may be very easily accomplished when said casing is tapered slightly as illustrated in Fig. 1, because as soon as the casing has been moved a slight degree it will completely release itself from the expanding force of the compressed ma-V terial. Therefore the tapering of the casing bears an important relationship to the remaining portions, of the construction, inasmuch as the second compressing operation is performed after the casing has been raised into the dotted line position of Fig. 1. On the other hand, in the arrangement shown in Fig. 5 the casing is split both at front and back, and the two halves are joined or hinged together by means of the hinges 21. Therefore, when a perfectly cylindrical casing is used, if it should be found that the casing cannot be easily raised, it may first be unfolded a slight amount, and afterward closed when in raised position.

The tapering of the casing as shown in Fig. 1 bears another denite relationship to the other portions of the structure, and to thev character and quality of the bale produced. This relationship is that the combination or association of a tapered casing with an armed upper press head serves, to eect the inturning of the edges of the paper and the like as the press head is forced down. This is because the edges of the paper and the like will tend to curl up over the ends of the arms as the arms are forced down. On account of the frictional contact of the papers with the inner surface of the casing there will be a dragV or pull on the protruding ends of the pieces of paper which will curl them up and to some extent force them into the body of the mass undergoing compression so that when the bale is completed it will be found that the ragged edges or surface which frequently constitute a source or cause of objection to the bale are eliminated or obviated. It will be noted from an examination of Fig. 4 that I have therein illustrated an upper press head having eight arms, whereas the lower head is illustrated in Fig. 3 as having only four arms. Vhile the number of arms to be provided on each press head is largely a matter of convenience or a matter of experiment in any case, still as a general proposition it will frequently be found desirable to have a greater number of arms in the upper press head than in the lower head. Y

While I have shown in the drawings and described in the specification one embodiment of my invention, still it will be evident that I am in nowise restricted to the same, except as may be called for in the claim, but that I include within the scope of my invention any equivalent constructions op-` erating in equivalent manners to produce Y equivalent results.

I cla-im.

A baling-press for the purpose specified, comprising in combination a base plate having a plurality of slots extending across its upper surface substantially on intersecting diameters, a press head movable toward and from the base plate, said press head having a plurality of arms lying in pairs on diameters substantially corresponding to the positions of the slots in the base plate, there being substantially diametrically extending slots on the under faces of saidarms for the accommodation of tie wires and the like, means for forcing the press head toward the base plate, and a suitable casing between the base plate and the press head, substantially as described.
