BALING- lPATENT* OEEICE.

LYNCHBURG, VIRGINIA.

PRESS.

SPECIFICATION forming part of Letters Patent No. 701,575, eared :rune 3, 1902.

Application filed August 24|v T0 all whom it may concerns v Be it known that I, MICHAEL KIRSHNER, a citizen of the'United States of America, and a resident of Lynchburg, in the county of Campbell and State of Virginia,have invented certain new anduseful Improvements in Baling-Presses,of which the following is a specication. A v I This invention relates toimprovements in the art of compressing and baling cotton and other material, andv has for one of its objects a machine or press which can Agive the complete compression to the material in a single machine instead of in two machines, as is generally the present practice. It is now quite the usualpractice to give preliminary pressure to the cotton at the plantation, and then the partly-pressed bale has to be removed to a more powerful press, sometimes at a great distance, where the final compression is given.

It is my aim to provide a press that is so simple and withal so efficient and powerful that it can be made sufliciently cheap to be within the reach of all plantations, sothat` the complete compression can be given to the material in a single press before the bale isv shipped. i

Another object is to provide a machine that will be suitable for baling, the material in a practical and commercial fire and Ywater proof covering. p j v,

With these andother objects in view,which will be hereinafter set forth, my invention consists in a press of the peculiarconstrnc'- tion, arrangement, and combination of parts, as hereinafter described in itspreferable embodiment and then definitely set forth by In the drawings which accompany and illus-V trate one way of carrying out my invention, Figure 1 is a side elevation of a press made in accordance with my invention, but with parts broken away to better show the operating mechanism. Fig. 2 is a vertical central section of the same. Fig. 3 is a horizontal section throughthe.cr ib s.. Fig. 4 is a group of perspective views, showing the'two cribs and the movable bed-plate. Fig. 5 isa sectional detail through the bale. Fig. G is a perspective View of a knockdown frame. Fig.

7 is a perspective detail of the movable bedserin no. 73,183. (No model) are securely bolted the upper cross-heads 3 and 4, within which is secured the -upper or stationary crib 5. This stationary crib is formed of a frame consisting of four cornerposts 6,which are connected together by crosspieces 7 on th'esides and wedge-shaped crossi pieces 8 on -the ends, which'latter'rest on the cross-heads 4, as shown in dotted lines in Fig. land in'full lines inFig."5.j AThe said crib 5 also consists of a series' of Vertical lslats9 between the c'orner-postsnas' clearly seen in Fig. 4.' l c' 'i M Coacting with the aforesaid stationary crib 5 is alslidingcrib' 10, consisting ofga rectangnlarframellandaseries of upright or vertical slats 12, which' are so spaced that they llit between the slats 9 of the stationary crib 5.v and slide or `telescope therein, as clearly shown in jFLig. '1. vThis sliding crib is lined with sheet metal or any other suitable material 13, and this lining 13 is provided with two slots or openings 14 for a purpose to be `hereinafter described.

15 designates a plunger or.. follower which is adapted to enter the cribs 5 and 10 and give the preliminary pressure to the material to be baled, and this plunger 15 is pivotally connected to a pair of curved connecting-rods 16 "16,'which in turn are pivotally connected to a pair of blocks v1,7 A17, fixed toa pair of swinging arms 18 18, pivotedtlov the main or fixed A,bed-plate 1. 't Pulleys 19 19 are journaled within the blocks 17 '17, and a rope v2O passes from these pulleys toa drum 21, mounted on and revolving with the shaft 22, driven from any suitable source of power. 'Itwill be obvious froin'the foregoing and the accompanying drawings that when power isfa'pplied to the shaft 22 to wind the rope 2O on the drum 21 the ends of the swinging arms 18 18 are brought toward each other, which causes the plunger or follower 15 to rapidly enter IOO in the positions shown in Fig. 2, and two heavy metal bars 23 23 are then passed under the cross-heads through the openings in the cribs and the openings or slots 14 in the criblining 13, when the plungeror follower 15 becomes fixed and now serves as a fixed platen,

against which the material is given its finalY compression, as hereinafter described.

Mounted on the posts or standards 2 is a sliding compressing-follower, that I shall hereinafter term the movable bed-plate 25, which is capable 'of a vertical sliding movement on the said posts or standards and which has formed on or connected therewith extended bosses 26, which provide long bearings on said posts and give great steadiness and rigidity to their movable bed-plate. This bed-plate is also provided with a pair of depending ribs or cross-bars 27, from which project two pairs of hubs 2S, forming a bearing for part of the mechanism for giving the final compression to the cotton or other material being operated upon. Bolted or otherwise secured to the fixed bed-plate 1 is a somewhat similar arrangement consisting of a central web 30 and two pairs of hubs 31. Each pair of these hubs 2S and 31 (there being four pairs in all) support journals or axle-pins 32 32 and 33 33, the journals 32 3o being situated directly over those numbered 33 33, and on these journals are rotatably secured the eccentric rollers or cams 34 34 and 35 35. These eccentric rollers or cams are also arranged in vertically-disposed pairs, the rollers or cams 34 being in rolling contact with the rollers or cams 35. As these eccentric rollers or cams revolve or roll on each other they necessarily cause their journals or axlepins to separate or move one away from the other, and as the lower set is fixed it follows that the whole movement is imparted to the upper set of journals, and as the latter support the movable bed-plate 25 the said bed-plate is thereby given vertical movement.

To impart rotary movement to these eccen-A trically-set rollers or cams, I form recessed gears 36 36 and 37 37 in said rollers, and between each pair of these gears (which in reality are worin-wheels) mesh worms 39 and 40, which are formed on opposite ends of a shaft 41, on which is fixed a worm-wheel 42, gearing with a worm 43, driven from a shaft 44 by any suitable power. (Not shown.) As the eccentric rollers 34 35 roll on each other and their journals approach or move away from each other, it is necessary to provide some means of supporting the shafts 41 and 44, the worin-wheel 42, and the worm 43, so that these parts may move vertically in order to accommodate themselves to the vertical movement of the eccentric rollers. To permit this movement, I employ the bearing 46 for the shaft 44, which bearing .is forked or bifurcated at 47 to support the shaft 41, the said bearing 46 having guides or standards 48, which pass through openings 49 in the fixed bed-plate l, and thereby retain the bearing 46 in its proper position.

On the movable bed-plate 25 are formed or secured bars 50, providing a recess 51, specially adapted to receive or hold a pan 52, which forms the bottom or lower part of my improved bale-coverin g claim ed in a separate application filed August 24, 1901, Serial No. 73,184. A similar pan 53 forms a top or upper part of my bale-covering, and I provide a knockdown frame formed of two parts 55 and 56, which is arranged to coact with said pans when the bale is being compressed. This frame is shown in perspective detail in Fig. 6 and is of the proper size to rest on the bars50,hereinbel`ore mentioned. Thisknockdown frame is formed with an inwardlyswelled or convex portion 57, the use and purpose of which will be hereinafter described, and with openings or slots 58 to permit the air to escape as the material is compressed.

The above is a description of the preferable embodiment of my press, and its operation is as follows: Assuming that the movable bedplate 25 and its operating mechanism are in the positions shown in Fig. 1, the movable crib 10 is pushed upward, the lower or bottom pan or section of the bale-covering 52 is placed within the recess l, and the frame 55 56 is placed over said pan and on the bars 50, and the aforesaid movable crib is then moved downward until it rests on the frame 55 56, as clearly shown in Fig. 1. The cotton or other material to be formed into the bale is then fed into the upper crib, and when a sulicient quantity is placed therein it is given a preliminary pressu re by applying high or rapid power to the shaft 22 and drum 21, thereby winding the rope 2O on said drum, drawing the swinging arms 13 18 toward each other, and forcing the plunger or follower within the crib 5 and giving the initial or preliminary pressure to the bale. Owing to the fact that the cotton or other material has not had any pressure before this action, a rapid movement can be given to the follower or plunger 15, and when the latter reaches the point shown in Figs. .2, 3, and 5 the heavy cross-bars 23 are inserted under the crossheads through the slots in the cribs. These cross-bars 23, coacting with the cross-heads'3, will prevent the plunger or follower 15 from moving upward, andthe latter now serves the purpose of a fixed platen, against which the final compression is made. Power is now applied to the shaft 44, which slowly operates the worms 39 and 40 through the medium of the worm 43 and worm-wheel 42 and rotates the eccentric rollers or cams, and as the latter roll on each other the upper shafts or journals 32 32 are caused to slowly ascend, which of course moves the movable platen IOO IIO

upward and gives the final compression to the material between'the two pans 52 and 53. It will be evident from an inspection of my drawings that owing to the gearing the upward movement is made very slowly and that as the rollers orl cams are eccentrically set with relation to their axes the leverage increases as the upward movement is continued. v I deem this very important,vas by its use Isecure a most powerful mechanism with very little wear and tear and an imperceptible amount of friction. When the rollers move just'half-way around, then the axes are at their extreme positions, and the bale is now compressed and power is shutoff and the rmovement of the movable bed-plate stopped.

I here wish to call particular attention to the shape of the interior of the knockdown frame o 56, which is formed with an inward swell or convex portion 57, which as the material is pressed causes a corresponding concavesurface between the pans, as seen in Fig. 2, so `that it will not be dificult to secure a fastening device to the pans. Some method of fastening the pans 52 and 53 must now be performed, and this is accomplished by first pushing the sliding crib slightly upward and thenremovingthe knockdown frame 55 56, which maybe done by removing the two screws securing the parts together. A fastening-strip 60,provided with hooked flanges 6l and 62, is then bent'around the bale, so that the hooked lianges 61 and 62 are in theproper position to coactwith similarly-hooked flanges 52t and 53',on the pans 52 and 5,3. In order to cause the hooked anges to properly engage eachbther, I prefer to first Wedge or force a bar 63 between the rear side of the fasteningstrip 60'and the posts 2 2, then force end bars 64 and 65 between the ends of said strip 460 and said posts 2 2, and finally forco a pair of thin bars 66' and 67 on the front, all as clearly seen in Fig. 7, `in which` tho bale is shown in dotted lines. As the bars 66 and 67 have a space left between them,

a suitable tool can-be inserted to bend down.

the tongue 68, which must previously have been inserted through thev slot 69. The fastening-strip is now held closely against the pans 52 and 53; but the hooked flanges are not in engagement with each other. To make them engage each other, the-operator applies power to the shaft 44, which through the intei-mediate gearing causes the movable bedplate 25 to descend, and the expansivev forcev of the cotton causes the pans to separate sufficiently to engage the hooked flanges of the locking-strip with the hooked a'nges of the pans 52 and 53, when said pans will be securely locked together. The bars 63, 64, 65, and 66 may now be removed, and after'the movable bed-plate has been allowed to descend the covered bale may be removed from t the press ready in every respect for shipment.-

. From the foregoing it will be seen that I have invented and produced a simple press for baling cotton and other material which is so simple and yet so very efficient that it can be used on the plantation to entirely compress l the bale in a single machine instead of two, as are now generally employed. It'will also be seen that when the material is baled it is in a fire and water proof covering that not only makes shipping and storing much safer, but materially reduces the care necessary in its handling, as well as the insurance rates, which arehigh for the old style of coverings.

I have shown in my drawings what I consider one of the embodiments of my invention; butit will be manifest to all that I do not limit myself to the exact constructions and combinations shown, as various alterations or modifications may be made at -will or Y one part or set of parts used without other parts without in any way departingfrom the line of my invention. Merely as examples it may be mentioned that thebars 50 may be made integral with the bed-plate 25 or they may be formed separately and secured theron, and the teeth forming the worm-Wheels 36 36 and 37 37 may be made integral with the eccentric rollers or they can be secured thereto, so as to rotate therewith'. Hence where in my claimsy I have specified the eccentric rollers as having gears or worm-wheels formed thereon I mean to cover the eccentric rollers made with teeth in any way equivalent to that Shown.
