PRE SS-B OX.

Patented April 28, 1908.

Application filed October 21, 1907. Serial No. 398,435.

To all whom it may concern:

Be it known that I, FRANK PHELPS, a citizen of the United States, residing at Wellston, in the county of Lincoln and State of Oklahoma, have invented certain new and useful Improvements in Press-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to baling-presses, and has for its object to provide an improved press-box of suitable construction to withstand the strains of heavy compression and at the same time be convenient to operate without the use of a counter-balance.

The invention will hereinafter be first fully described by reference to the accompanying drawings, which form a part of this specification, and then more particularly pointed out in the claims at the end of this description.

In the drawings, the type of press selected for illustrating the invention is a revolving double box-press. The invention is however applicable to the many different styles of presses, either of the single-box or doublebox type.

Figure 1 of said drawings is a diagrammatic view of the revolving double boxpress. The left hand press-box therein is shown in elevation, and represented as in,

closed position; while the right hand pressbox, shown in verticalsection, is represented in open position, the bale of cotton or other material being represented as having been com ressed between the plun er and presshea The position of the let hand pressbox is of course reversed with respect to the position of the right-hand press-box, since the revolvin of the apparatus carries the boxes aroun for successive use in connection with the plunger and press-head. Fig. 2 is a perspective view of the press-box which is the subject-matter of my resent invention. Fig. 3 is a plan view of the press-box when opened. Fig. 4 is a plan view of the press-box when closed.

As the construction and operation of a re volving double box-press is well understood, and as the press shown in Fig. 1 is merely selected as a suitable type for illustrating my present invention, a brief reference to the parts of the press will be sufficient.

A denotes the central pivot post or column, and B denotes the lateral upright orstandshown), and connected at the top y a yoke or cross piece 0, these parts constituting the main frame-work of the press. Supported by any suitable frame or table D, which is revoluble on the center post A, are the two press-boxes E, E, adapted to be revolved one after another into position to receive the plunger F, working in coo eration with the press-head G, so that one ox may be filled with the cotton or other material that is to be compressed, while the bale is being formed in the other, in the usual manner with this class of machines.

Fig. 2 represents the press-box E as it would appear at the right hand of said Fig. 1. As previously stated, the left hand box in Fig. 1 is shown in reversed position, that is its rear side faces front. When the frame or table is turned to bring the left hand pressbox to the right hand side, over the plunger, it would then appear in the same position as shown in Fig. 2.

As understood by those familiar with the art, the main portion of each press-box is rigid or fixed, while the portion in which the bale is compressed (in this .case the upper end of the box) is se arable, its sides being removable or disp aceable for releasing the bale. As both boxes are alike, the following descri tion of one will suffice. The letter E is app ied in the drawings on the main rigid or fixed section of the press-box, or that portion of the box where the sides are fixed and through which the cotton is forced by pressure into the separable section of the box, the latter constltuting an extension of the main section.

The numerals 1, 2, 3 and 4 designate res ectively the four displaceable or removable sides of the upper separable section of the box. The front and rear sides 1 and 3 are or may be hinged to swing outward as shown in Fig. 4. The left side 2 is displaceable by receding from the bale as shown in Fig. 1. The 0 posite or right side 4 is hinged at 5, preferabfy at a oint below the upper section of the box, an drops back of its own weight when the upper section is opened.

Two beams or bars 6 are secured across and fastened to the left side of the box, that is to the main or fixed section of the pressbox. These beams support between them two vertical rods 7, the u per ends of which rods extend through and above the upper one of the cross-bars 6. On the corresponding side 2 of the upper separable section of the box are similarly secured two cross-bars 8.

Across the front of the press-box are arranged three beams 10, 11 and 12. Across the opposite or rear side are similarly arranger three beams, likewise denominated 10, 11 and 12. The beams 10 are arranged near the lower part of the press-box, while the beams 12 are arranged across the upper separable section. The middle beams 11 may extend along the joint between the main lower section of the box and its upper separable section, so that said beams when secured in place will hold and brace both sections of the press-box. The lower beams 10, also the middle beams 11, have L-shaped ends 13 which embrace the corners ofthe press-box. At the left side, the extremities of said L-shaped ends or parts 13 are pivotally attached on the vertical rods 7, which latter extend through holes therefor in said parts 13. The upper beams 12 have such L-shaped arts 13 only at their right hand ends, whic embrace the right hand corners of the box. The left-hand ends of said beams 12 are connected by pivot pins or bolts 14 to the upper left cross-bars 8. The middle beams 11 are similarly connected by corres ondingly located. pivot pins or bolts 14 to t e lower cross-bars 8. The pivot pins or bolts 14 stand at the outer ends of short longitudinal slots 15 in the said bars 8.

At the right side of the press-box (appearing as the left side in the left hand half of Fig. 1) there are two vertical pivot rods 16 and 17, one at the front and one at the back, each running through holes therefor in the respective set of beams 10, 11 and 12. T 0 one of said rods 16 (Figs. 1, 3 and 4) are attached the angled or L-shaped ends of preferably three tie-rods 18, the opposite ends of which tie-rods are provided with bent or angled parts 19 which are slotted to engage hooks 20 on the other pivot rod 17. Said pivot rod 17 has thereon a lever 21 whereby the rod can be turned to lock the hooks 20 in the slots 19, or to release said hooks from said slots and permit disengagement of the tie-rods 18 from the pivot rod 17. The turning of the pivot rod 17 to lock the hooks in the slots also tensions the tie-rods, thereby tightening the box. When the hooks are fastened or locked in the slots, the lever 21 lies across the front of the press-box and may be fastened by a loop 22 or other suitable means.

The operation is as follows: hen the box is closed and fastened, it will be seen that the beams 11 and 12, attached to the cr'ossbars 8 at one end and having their L-shaped parts 13 embracing the corners of the box at the other end, hold firmly in position the opposite displaceable sides 2 and 4 while the said cross-bars 8, attached to said beams 11 and 12, hold together the front and back sides 1 and 3 at the left of the box. The front and back are held in position at the right hand side of the box by the tie-rods 1S connecting the pivot posts 16 and 17 on the opposite faces of the box.

To open the box, after the material has been compressed and formed into a. bale, the lever 21 is first unlocked and thrown outward to disengage the hooks 20 on the pivot rod 1 7 from the slotted ends 19 of the tie-rods 1S, and the latter are then disengaged and swung away from the box. The front beams 10, 1 l and 12, carrying with them the pivot rod .17, are then swung around on their left hand pivots; similarly the rear beams 11), 11 and 12, carrying the other pivot rod 16, are swung outward, both sets of beams being carried to the full open position shown in Fig. 3, and carrying with them the front and rear sides 1 and 3 of the upper separable section of the box, the said sides being attached to the upper beams 12. Since the beams ll) and 11 have their L-shaped left hand ends 12'; pivoted on the vertical rods 7, said beams when swung out to open position. are thrown behind said eross-bars 6, the effect of which is to throw back the lower cross-bar S. The upper beams 12 and upper cross-bar 8 being respectively attached to the separable sides 1, 2 and 3 of the upper section of the box, are caused to conform to the movements and positions of the beams 10 and 11, and lower cross-bar 8, thus, when the box is opened, the separable sides 1 and 3 being thrown outward as in Fig. 3, the left hand side 2 auton'iatieally recedes from its normally closed position, as shown at the right hand half of Fig. I. This leaves the opposite or right side -l free to fall back of its own weight.

Inasmuch as the box is intended more especially to be used with a heavy steel press, and subjected to a heavy compressing strain, the sides of the press-box are preferably made of steel plates with the beams, cross-lmrs and hinges also of heavy steel, though I do not limit myself to these or any specific malerials.

TVhile I have shown what I now regard as a preferred form or embodin'lent of the invention, it is obvious that the beams, cross-bars, tie-rods, etc., may be increased in number or changed in arrangement, and that the details of construction may be n'lodiiied in various ways without departing from the principle and scope of my invention, so that I do not desire to restrict myself essentially to the specific construction herein illustrated.

What I claim as my invention and desire to secure by Letters Patent of the United States is:

1. A press-box having displaceable or separable sides, and a three-sided holding frame inclosing and secured to the three corresponding separable sides of the box, two opposite sides of said holding frame be being pivotal ly-mounted adjacent to the third side so as to swing oppositely outward, and having sliding-pivot connections with said third side arranged to move the latter outward by the swinging apart of said opposite sides, whereby the opposite sides of the box are swung outward toward the third side which automatically recedes, and de tachable connections adjoining the free ends of said holding-frame across the fourth side of the box.

2. A press-box having a fixed section and a separable section thereon, a three-sided holding-frame surrounding the box on three sides, the intermediate side of said holdingframe being attached to the corresponding side of the box and having that portion thereof which is attached to the separable section of the box capable of a receding displacement, the two other sides of said holding frame being hinged or pivotally-connected to said intermediate side and having sliding pivot connections with the said displaceable portion thereof, whereby when said two sides of said holding-frame are swung outward the displaceable portion of said intermediate side recedes and carries with it the corresponding displaceable side of the separable section of the box, and means for connecting the sides of said holding-frame across the fourth side of the box.

3. A press-box having a lower fixed section and an upper separable section thereon, a three-sided holding-frame surrpunding the box on three sides, and having means for em-' bracing the corners of the box at its fourth side, the intermediate side of said holdingframe being attached to the corresponding side of the box and having that portion 40 thereof which is attached to the separable section of the box capable of a receding displacement, the two other sides of said holding-frame being attached only to the sides of the separable section of the box and being hinged or pivotally-connected to said intermediate side of the frame and adapted to be swung oppositely outward, the arrangement being such that when said .two sides of said holding-frame are swung outward the displaceable portion of said intermediate side recedes and carries with it the corresponding displaceable side of the separable section of the box, and detachable tie-connections between the free ends of said holding-frame at its fourth side.

4. A press-box having separable or displaceable sides, and a three-sided holdingframe inclosing said box on three sides, the intermediate side of said frame being secured 0 to the corresponding separable side of the box, the other two sides of said frame being hinged to swing oppositely outward and being so pivotally-connected to the said intermediate side as to move the same outward by 5 the swinging outward of the said'two hinged sides, a plurality of tie-rods attached to the free end of one of said hinged sides, said tierods having slotted free ends, and. a pivotpost carried by the free end of the other hinged side having hooks for engaging in the slotted ends of said tie-rods, said pivot-post having a lever for turning the same to release said hooks or to engage them forcibly in the slotted ends of the tie-rods and to tension the latter.

5. A press-box having a fixed section and a separable section thereon, and a holdingframe comprising opposite sets of beams (as 1 1 and 12) arranged across the front and rear faces of the box, cross-bars (as at 8) secured 0 on one displaceable side of the separable sec tion of the box, sliding pivot connections between the ends of said beams and cross-bars, at least one opposite pair of said beams (as 11) having angular or L-shaped extensions 5 hinged or pivotally-mounted on the fixed section of the box at the aforementioned side thereof, whereby the swinging outward of the two sets of beams causes the said cross-bars to recede and carry back the separable side attached thereto, and means for connecting the free ends of the two sets of beams across the side of the box which. is opposite said crossbars.

6. A press-box having a fixed section and a separable section thereon, and a holding frame comprising opposite sets of beams arranged across the front and rear faces of the box, at least one opposite pair of beams (as 11) havingangular or L-shaped extensions at both ends embracing the corners of the box, said extensions being hinged or pivotally-mounted on fixed pivots at one side only of the box, cross-bars secured to the corresponding displaceable side of the separable section of the box, sliding pivot connections between said cross-bars and the adjacent ends of both opposite sets of beams, the aforesaid fixed pivots of the one set of beams being between such sliding pivots, the other opposite set of beams (as 12) having angular of L-shaped extensions at their free ends only and embracing the corners of the box at that side, and tie-rods carried by the swinging end of the set af beams at one side adapted to be connected with the swinging end of the set of beams at the opposite side across the fourth side of the box.

7. A press-box having a fixed section and a separable section thereon, and a holding frame comprising cross-bars secured on one side of the fixed section, rods extending between and connected to said cross-bars, other cross-bars secured on the corresponding displaceable side of the separable section, and opposite sets of beams arranged across the front and rear of the box, two opposite pairs of said beams having L-shaped or angular extensions embracing the corners of the box at the aforesaid side and pivotally-mounted 130 on said rods, one of such pairs of beams having also sliding pivot connections with the adj acent cross-bar on the said displaceable side of the separable section, and the third opposite pair of beams, Which lie across the displaceable front and rear of the separable section, having similar sliding pivot connections with the other cross-bar on the aforesaid displaceable side.

8. A press-box having displaeeable or separable sides, and a three sided holding frame comprising cross-bars secured on one displaceable side of the box and opposite sets of beams across and secured to the front and rear of the box and having sliding pivot eonnoctions with said cross-bars, at least one opposite pair of said beams having angular extensions mounted on fixed pivots between the said sliding pivots.

9. A press-box having displaceable or separable sides, and a three-sided holding-frame inclosing and secured to the three corresponding separable sides of the box, two opposite sides of said holding-flame having sliding pivot connections to the third or intermediate side and having angular extensions mounted on fixed pivots between said sliding pivotal connections, whereby the swinging open of two opposite sides of the box will cause the third side to recede.

10. A press-box having displaeeable or separable sides, and a three-sided holdingfraine inclosing and secured to the three corresponding separable sides of the box, two

opposite sides of said holding frame being of said swinging sides and the receding side adapted to displace the latter by the swinglng open of said swinging sides.

In testnnony whereof l allix my signature, 111 presence oi two witnesses.
