SPECIFICATION forming part of Letters Patent No. 6G 6,293, dated January 22, 1901.
Application led March 2 Z, l 89 8.
T0 all whom t may concern:
Be it known that I, SAMUEL J. WEBB, a citizen of the United States, residing at Minden, in the parish of Vebster and State of Louisiana, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification.
This invention relates to that class of baling-presses in which a movable platen is operated from a suitable engine or other actuating device through the medium of levers and links; and it consists of certain improvements to strengthen and simplify the construction of the press and whereby to secure a greatly-increased pressure toward the termination of the movements of the platen.
It also consists in certain compensating devices whereby the maximum pressure may be exerted upon the bales, regardless of the varying thickness thereof, as more fully described hereinafter.
In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts,Figurelisafront elevation ofapress embodying` the invention, parts being in section. Fig. 2 is a side elevation with parts in section. Fig. 3 is a front elevation, parts being in section, of a modified form of press. Fig. 4t is a side elevation of the same, parts being in section. Fig. 5 is a detail sectional view of a modified form of platen. Fig. 6 is a plan View thereof removed from its support. Fig. 7 is a detail sectional View of another modified form of platen. Fig. 8 is a plan view thereof. Fig. 9 is a detail view of one of the triangular levers. Fig. 10 is a face view of the same, and Fig. ll is a detail plan view of a platen.
The frame of the press is constructed in any suit-able manner to support the other parts, including the upper platen A and the lower platen B, both of which may be movable.
It is common to provide the platens of presses with grooves through which to pass the tying-bands while the cotton is held compressed between the platens. It is desirable, however, to sometimes apply the bands in sections to the faces of fiat platens before the bale is introduced. The presence of the usual grooves interferes with this, and I therefore provide the platens with grooves but Serial No. 674,799. (No model.)
instead of making them at right angles to the sides of the platens I make them at a slightlyincreased angle not sufficient to interfere with the usual application of the bands after the bale is compressed, but sufficient to aiford a flat bearing-face for each band-section adjacent to each edge of the platen when the said band is laid at right angles to the sides of the platen and crossing the groove, as shown in Fig. ll.
As shown, the frame is provided with two stramps 2 2, curved at the top and extending over a block E, which is rigidly fastened thereto and connected at the bottom by bars 3, and the lower platen B slides between these straps and moves up and down under the action of triangular levers D D', each of which is pivoted at 0c to one corner of the lower part of the frame and is also pivoted at y to the outer end of a link 5, the inner end of which link is pivoted at a' to the lower platen. These triangular levers are lifted and swung inward to lift the lower platen B by means of an engine C, which, as shown, is at the top of the frame and has a piston 7, having a cross-head 9, connected by links l0 wit-h the lower pivotal point w of the triangular levers D D', these lower pivotal points being in a plane intermediate those on which the levers are pivoted to the frame and on which the links 5 are connected to the levers when the platen B is in its lowered position. As a consequence of this arrangement it will be obvious that as the platen is lifted there is a grad ually-increased leverage upon the fulcrum x, whereas the leverage at the pivotal point y gradually decreases, and when the platen is in its elevated position the pivotal point y is in a plane intermediate those occupied by the fulcrum c and the pivotal point w, as shown in diagram Fig. 9, the links 5 occupying very nearly a vertical position and acting as toggles with powerful eect as they reach the terminal positions.
In order to prevent injury to the levers D D', resulting from their forcible contact with the frame, and to limit the movement of various parts of the press when the lower platen is elevated, said levers are provided at their inner faces with buffer-blocks 28 of yielding material, preferably of wood, which blocks make contact with side bars 29 of similar IOO material, constituting part of the frame or with other bearings upon the frame.
The engine C is constructed in any suitable manner and is provided with an inlet-pipe 1&1, communicating with a steam -generator or other source ot' motive duid for the admission of steam, the., when the piston 7 requires to be lifted. lVhen the press is not in operation, the engine cylinder becomes cool, and if the platen B is in its lowered position when steam is admitted to the cylinder there is liability of the cylinder being fractured by the admission of steam only-to its lower end resulting from the non-uniformity of the eX- pansion of the cylinder. In order to guard against this, there are projected above the cylinder two separated uprights 12, through openings near the upper ends of which e.- tend engagingdevices in the form of bolts 13, adapted to engage with the cross -head 9 when it is elevatedand hold the piston in the upper end of its cylinder. By this arrangement it will be apparent that preliminary to beginning operating and lowering the piston the whole piston-chamber may be filled with steam, resultingin the uniform heating of the cylinder and in its uniform expansion. The uprights 12, in addition to serving as supports for the piston and lower platen, constitute guides for the cross-heads 9 and prevent lateral vibration thereof.
The platen A may in some instances be secured immovably to the block E; but I prefer to give it an independent movement for the purpose of increasing the cficiency of the press. This may be done by means of an engine or engines intermediate of the block E and the platen A. As shown in Figs. 1 and 2, there are practically three cylinders and three plungers, two plu ngers 18 18 extending from the block E into the cylinders in the platen A and one plunger 17 extending from the platen A into a cylinder in the block E. By making cylinders in the platen A, I am enabled to use a platen of suilicient depth to get the required strength without unduly increasing the height of the press, as would be necessary if a platen of the required strength was made and the plungers then all extended from the platen into cylinders in the block E.
As shown, there is a channel 2O extending through the plunger 17 with lateral channels extending to the cylinders in the platen A, so that water or other iuid admitted under pressure through a pipe 2O to the cylinder in the block E may pass to the other cylinders. In the operation of the press the water is first admitted through the pipe 20, so as to force the platen A downward upon and partly compress the bales lying on the platen B. After the platen A has moved to the limit of its movement a cock a in the pipe 20 is turned so as to lock the'water in the pipe and in the cylinders, thereby preventing any upward movement of the platen A under pressure. The platen B is now lifted by the action of the engine C until the bale is compressed to the requisite extent. It it should be found that the bale is so large or so compressed that .the toggle-levers cannot be moved to their full extent to secure their full effect, then by slightly opening the valve a a portion of the fluid can pass from the cylinders above the platen A, and the latter is allowed to lift just to the extent necessary to permit the togglelevers to be brought to their completed movement and their full efficiency secured. I am thus enabled to adjust the position of the platen A under pressure. \Vhen the bale is removed, it is necessary to restore the platen A to its upper position. This may be donc by means ol' two small engines I I, each consisting of a cylinder 21, secured to the frame and containing a piston 22, connected by a piston-rod 23 with the platen A. The cylinder communicates through a pipe 24 with a supply of motor duid under pressure, which is suilicient to lift the platen A and bring it against the under face of the block E. At the same time the iluid has free passage lo and from the cylinders 21, and when any superior force is exerted to depress the platen the fluid will flow from the cylinders 21 back through the pipes 24., The cylinders 2l,witl1 their pistons and lluid under pressure, therefore constitute in a man ner counterlmlances for the platen.
It is not essential that there should be two plungers 1S, as the number may be increased or diminished. As shown in Fig. 7, there are two plungers 18, and the plunger 17 is dispensed with. In Fig. 5 the cylinders 21 are somewhat dil'l'erently arranged from what they are in Fig. 1.
It is not necessary that the movable platen A shall be the upper platen. As shown in Figs. 3 and 4, it is the lower platen, the upper platen being ixed, the lower platen-bed movable, and the movable platen A being upon this lower bed.
It will be obvious, too, that instead of connecting the straps 2 2 to the bars 3 of the framethe said straps may be formed contin nous and extended around the upper platen and also around the lower stationary bed, as shown in Figs. 3 and 4.
Without limiting myself to the precise construction and arrangement of the parts shown and described, it will be obvious that such construction and arrangement may be varied without departing from the spirit or scope oit' the invention and some features of the invention may be used without others.
I claim- 1. In a baling-press, the combination of the platens A and B, duid-actuated pistons 22 and pipes and control-valves to yieldingly support the platen Ain its elevated positions, an actuating-piston and means for introducing fluid under pressure above the piston to depress the latter t0 partially compress the bale, a valve to lock said duid under pressure when the platen is depressed, and means to elevate the platen B to complete the IOO IIO
compression of the bale, substantially, as set forth.
2. The combination of the frame, platen, cylinders and plungers, pipes for cond ucting a fluid to and from the cylinders, counterbalance-cylin ders having pistons connected with the platen, and pipes for conducting inid under pressure to the counterbalance-cylinders to lift the platen when required, substantially as described.
3. The combination of the frame, platen A, intermediate cylinders and pist-ons, cylinders 2l having pistons connected with the platen, and a communication between said cylinders and asource of lluid under pressure, substantially as described.
4. The combination of the frame having a cylinder and plungers 1S, 18, a platen having a plunger and cylinders to receive the plungers 1S, 18, and pipes for permitting the passage of Huid to and from the cylinders, suhstantially as described.
5. The combination of thelower platen, engine and connections for moving the platen, upper platen and engine for moving the same, and a valve for locking fluid under pressure in the engine for moving` the upper platen, substantially as described.
0. The combination of a frame of a press recessed to form' a cylinder, a platen recessed to form a cylinder, a piston projecting from the frame into the cylinder of the platen, a piston projecting from the platen into the cylinder of the frame, and a communication connecting the cylinders of the frame and platen with a source of lluidsupply under pressure, substantially as described.
7. In a press, the combination of the frame, two platens, an engine and its piston, triangular levers pivoted to the frame'and connected to one of the platens and to the piston, and a buffer carried upon the triangular levers to engage a buffer on the frame for limiting the movement of the parts of the press, substantially as described.
8. In a press, the combination of two platens, means for moving one of the platens to and from the other, and one of said platens being formed in its face with parallel diagonal grooves, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
