BALING-PR-Ess.

SPECIFICATION forming part' of Letters Patent No. 294,551, dated March 4, 1884.

Application filed January 8, 1884. (No model.) Patented in England April 28,1S83,No.2,155.

To al!) wwm may concern,.-

Be it knownthate, JAMES WATSON, of London, England, have invented certain new and ,useful Improvements in Ealing-Presses, of

which the following is a speciiication. A

My invention `consists of improvements in baling-presses, and has special reference to presses in which th'e cotton, jute, or other materiall to be formed into a bale receives first a preliminary pressure by one or more rams, and then'a nal or iinishing pressure by one or more other rams. v

In a former patent, dated August 28, 1883, No. 283,838, I described a press of the kind above referred to, in. which a preparatory ram anda finishing-ram are arranged in parallel planes,- and in which a set of iinishing-boxes is mountedV to revolve around an axis over said rams and arranged to be brought successively into coincidence therewith, and a set of preparatory boxes is also mounted to-revolve around an axis below the iinishingboxes, and arranged to be brought into coincidence, successively, with the preparatory ram and a 11- ishingbox, wherebythe preparatory ram is enabled toiorce the material fronithe preparatory box into the finishingbox,and whereby the latter box, with the partly-finished bale, may be swung round to the nishing-ram, so that the iinal or nishing pressure can be given thereto. rllhe finishing-boxes described in my said former patent are each composed of two main doors forming the two sides' ofthe box; of an inner end to which said doors are hinged; of an easing-door forming 'the outer end; oi'a top lashing-plate, and vof a toothed sliding stop, which supports the bale as soon as the follower of the preparatory ram begins to descend. y

Now, the objects of my present invention are to simplify the construction of that part of the press into which the cotton or other material is forced from the preparatory bo-xes, to diminish the weight which has to be lswung round from the preparatory ram to the finishing-ram, and vice versa, and toV construct the press so that, without increasing lthe number or the power of the iinishing-rams, the outturn from the press is much increased.

My invention, with the above objects, consists, first, in hinging the main doors of the upper boxes to a iixed support,-so that they do not swing round with the partlyfinished bale, and in rigidly fixing to the center piece (which, in the press described in my said former patent, forms the inner end of the revolving finishing-box) one end of a wrought-iron or steel frame to supportthe bottom of the Vpartly-nished bale, this frame having a central opening of exactly the same dimensions as the sectional internal area of the preparatory boxes; secondly, in constructing the press y In the annexed drawings, Figure 1 is au elcv vation, and Fig. 2 a horizont-al section, of a press embodying my present improvements Fig. 3 is a vertical section through one of the preparatory portions of the press.

a a are the nishing-rams; b b, the two preparatory rams disposed, respectively, on the two sides of the rams a a. y

c c o c arethe two sets of preparatory boxes. (There are two shown in each set, but this number may be varied.) i

d d are columns, around which the sets of boxes c c c c can be revolved.

e e e e are the main doors of t-he upper boxes. They are hinged to the columns eZ d.

ff are center pieces mounted, respectively,

upon columns g g, and forming the inner ends of the upper boxes.

h h are wrought-iron or steel frames rigidly xed at one end to the piecesff. The openings fifi in these frames are of the same di- Ymensions as the sectional internal area of the boxes c c.

formed. The bottom parts of the doors Z Z.

also catch int-o the-frames h h' and support them against downward pressure, due to the expansion of the bale when held between the frame and the lashing-plate. As seen in Fig.

3, the width of the upper boxes-that isto IOO say, the distance between the two main doors rIhe bale, as thus held in a sort of chamber or when closedis slightly greater than the width of the openings in the frames h h.

The doors d e', at the left-hand side ot' the press, are seen fully open in Figs. l and 2, while the doors c c, at the right-hand side, are broken away in Fig. l, and shown partly open in Fig. 2. rIhese figures also showthe finishing-rams in the position they occupy after having given the final or finishing pressure to a. bale which has been brought from the preliminary ram at the left-hand side, and they show the preliminary rain and parts -at the right-hand side in the positions they occupy when said ram has completed the preliminary pressure, and the main doors have been opened.

The action ot' the press (referring l'or the present only to the right-hand side) is as follows: The parts being in the positions seen in the figures, (except that the doors ce must be closed, and the ram b must be at the bottom ol` its stroke,) and the box c which is in line with the ram Z) being f'ull of' the cotton or material to be compressed, the ram rises into the position seen in Fig. l., and in so doiugt forces t-he cotton from the box c into the upper box.

Then the ram has reached this position, the

doors e c are unlocked, either automatically by the rise ot' the ram (in a manner well understood) or by hand, aud pushed back to the position seen in Fig. 2. The men may then commence lashing` the bale, the ram meanwhile holding it up. rI`he meu pull the ropes or hoops partially tight, and in order to prevent the ends slipping they insert a wooden wedge into the rope-grooves ot the top lashing-plate, 7s, above the rope or hoop ends, so as to press them against the bale; or the bale may be held on the top ofthe l'rame without any lashing at all, the lashing conuneneing only after the bale is in position over the flnisliinglams. r]he ram I) is then allowed to descend clear ot' the frame 71, and the bale is partly held in position by friction against the parts which embrace it, aud the ropes or hoops prevent it returning into the box. It the bale expands downward so f'ar as the f'rame l, its edges cannot go past the top ot' this f'rame, as the opening therein is not so wide as the distance be tween the doors c c when closed, andthe bale expands somewhatatter the doors are opened. The ropes or hoops are now caught and held f'ast by the expansion of" the bale pressing them against the top inside edge ot` the frame l1.

box without sides, is now swung round 011 the column f/ into position over the finishing-rams a a, and these rams riset'o give the final pressnre, the men, as the rams rise, continuing the lashing oft-he bale. Iu themeantime the other box c, full ot' material to be compressed, has been brought in line with the ra-m b, and the moment the bale is tumbled out of the press, and the follower ot' the rams a av f'alls clear ot' the frame 71, this frame and the other parts which revolve therewith are swung back into line with the ram b, the doors c are shut, and'this ram rises to press another bale. The Sallie actions take place at the left-hand side of the press, the movements and operations at the two sides being ot' course so timed that the bales are brought to the finishing-rams alternately, f'ro 1n the two preparatory portions ol' the press.

Il' desired, the sliding stops described in my .f said former patent may be fitted to the press,

and made to pass either through the lframes 7ly h or above them, to support the bales when the followers ofthe rams b b descend; but I do notconsider these stops necessary with the arrangement above described.

\Vhat I claim is- 1. The doors e c, hinged to a fixed piece, d, in combination with a frame, /l, fixed at one cud to a center' piece, and with a lashingplate, lf, and easing-door I, said pieces l1, f, lf, aud l being mounted to revolve. so as to be brought into coincidence at one time with a preparatory ram or rams, and at another time with a finishillig ram or rams, substantially as and for the purpose set f'orth.

2. The combination, with the finishing ram or rams (L (1., ot' the two preparatory rams l) b, two sets ot' preparatory boxes, c c c c, two pairs of main doors, c 0 c c, and two sets ot' revolving or swinging deviees, /`l1 l." l andf ll le Z, for swinging the partly-finished bales from the preparatory rams to thetiushing ram or rams, substantially set forth.

In testimony whereof I have hereunto signed my names in the presence ot' two subscribing witnesses.
