ALBERT LIVINGSTON BLAOKMAN, OF LONDON, ENGLAND.-

APPARATUS FOR COMPRESSING FIBROUS MATERIAL.

SPECIFICATION forming part of Letters Patent No. 430,986, dated June 24, 1890. Application filed April 15, 1889. Serial No. 807,831. (No model.)

To all whom it may concern:

Be it known that I, ALBERT LIVINGSTON BLACKMAN, a citizen of the United States, at present residing at London, in England, have invented certain new and useful Improvements in Apparatus for Compressing Cotton or other Fibrous Materials, of which the following is a specification.

My invention has relation to an improved bale-compress car, and is designed to serve as a portable compress for handling and compressing bales of cotton or other material; and it has for its object to provide a corn bined powerful bale-compress, actuating-motor, and car, which may be run on railwaytracks from station to station or other location where cotton may be stored,and may be economically operated by hydraulic power, steam, or other force, thus saving the great additional costof transportation incident to shipping uncompressed bales to compressing stations or to trade centers or seaboard ports.

A further object is to adapt to my balecompress car suitable appliances for economically handling bales of cotton or other matcrial by mechanism;

A further object is to adapt to my balecompress car suitable motor-power to operate the bale-compress.

In the accompanying drawings similar letters of reference indicate corresponding parts.

Figure 1 is a vertical longitudinal section of a bale-compress car, showing the bed, the trucks, the compress, the hydraulic cylinder, the stirrup, the actuating-piston, and a connecting steam-cylinder, the force-pumps, lifting-cranes, and an arm with fingers for removing the compressed bale. Fig. 2 is a plan of the same, showing the arm with fingers in position below the jaws of thebale-compress, a series of accumulators, and connectin g-pipes.

Fig. 3 is a vertical cross-section taken between the jaws of the bale-compress, the sup- 7 porting sides of the car-bed, with ways for the.

stirrup, and the stirrup in cross-section adjusted therein. Fig. at is a plan of Fig. 1, showing the arm with fingers in position to discharge a compressed bale. Fig. 5 is the same, showing the arm with fingers in position to receive and hold the bale being com pressed.

In a rectangular car-body A of suitable depth, constructed of metal securely riveted together, and having a substantial top or platform A and bottom A and mounted on trucks B, adapted to travel on railways, is a central well-like vertical opening 0 to permit of the passage of a bale of material to be compressed. The curbing of this opening 0, which latter passes vertically through the car-bed, is so substantially framed that the car-bed is as firm and strong at this point as at any other.

Within and along the sides of opening 0, and parallel with the sides of the car-bed,

grooved ways N N are constructed and adapted to receive and retain, while permitting ot the free movement of, stirrup G which operates the movable compress platen 0 which latter is arranged wholly within the car-bed near one side of the opening 0, as shown in Fig. 1. Also within the car-bed, toward the end and on the side of opening 0 opposite to that of platen O is arranged a stationary compress-platen 0 a part of and attached to and forming an end of a stationary hydraulic cylinder 0, the latter being the first of a series of two or more of such cylinders arranged coaxially, as in a tandem engine, within the car-bed and designed to provide the power for operating the compressor. In Fig. 1 I show two of these hydraulic cylinders O and 0', provided with pistons 0 0 secured upon piston rod 0 which passes through suitable stuffing-boxes O to prevent the escape of fluid and terminates in a combined grooved yoke 0 adapted to receive and secure one end of the stirrup C, and a knucklejoint 1, by which itmay be connected with the piston-rod of a piston I from a steam-cylinder I, employed for returning the parts and releasing the compressed bale. All of these parts are secured to and serve to strengthen the car-bed.

The sides of the stirrup 0, as seen in Figs. 2 and 3, pass along the sides of the car-frame A and are supported in grooved guideways N N. The other end of the said stirrup passing along'in the grooved sides embraces the semicircular grooved projection O of the movable compressor-platen O 0 is a cap transversely spanning over the end of the stirrup and secured to the projection 0 for insuring the movements of platen '0 at all times with said stirrup.

D is an air-pump rigidly secured to and forming part of platform or car-bed A, and is connected through pipes G by branch pipes G to pipes or chambers E forming part of the accumulators E E.

D D are hydraulic pumps rigidly secured to and forming part of the car-bed or platform A and connected by pipes D and D with the accumulators E E". The accumulators E, E, E and E form accumulators to augment the force in operating hydraulic presses, and are rigidly secured within the car-bed, as shown in Figs. 1 and 2, and serve to add strength to it.

Passing vertically through the car-body is another opening 11, in which is rigidly secured a cylindrical standard J ,Which extends above the plane of the car-bed A, and through which a device J, for supporting and discharging compressed bales, is operated. Said supporting and discharging device J has a horizontal arm J 2 arranged beneath the car-bed and terminating in a grid or fingers J. Said horizontal bar is secured to a vertical shaft J which passes up through the standard J and is capable of being practically rotated and moved up and down in the standard by means of a chain J a toothed rack, or its equivalent. The upper end of standard J supports a bracket J which is pivoted thereto. The projecting arm of the bracket J 5 terminates in a handle J by means of which the fingers or grid J and terminating horizontal arm J 2 may be swung to a position at right angles to its former position, as hereinafter described. To the bracket J 5 is pivoted a semicircular lever J7, provided with a projecting handle J To a suitable point of the curved surface of the lever J 7 is attached one end of a lifting-chain J or its equivalent, the other end of which is attached to the vertical shaft J By this device it will be seen that by raising the handle J 8 the grid or fingers J, which are provided with short spikes to prevent the bales from slipping therefrom, will be lowered from a posit-ion immediately in contact with the bottom of the car-bed, as shown in full lines in Fig. 1, to a position shown by dotted lines in the same figure, carrying with it the compressed bale, and that by moving the arm J 6 in a direction at right angles to its normal position the fingers or grid J will be swung laterally, carrying the compressed bale from under and clear of the car. (See Fig. 4.) There is also rigidly secured to the car-bed a crane H, with projecting arms 1-1 H, for lifting into position betweenthe platens or jaws, C C of the compress the bales of material to be compressed. The lifting-crane His so constructed that the parts of the upright may telescope into each other, so that the crane may be raised when needed for use and lowered while moving. The lifting-crane H is connected by suitable induction-pipes (not shown) with the force-pumps D D and by eduction-pipes (not shown) .with the fluid-reservoir F, and is operated by hydraulic power.

F is a fluid-tank from which the pumps are supplied, and is arranged Within the car-bed, and F is a pipe fitted with a valve F for allowing the water to escape from the cylinders O 0 back into tank F.

The pistons O are adapted to be operated by hydraulic power, for generating which I prefer to use pumps D and D as hydraulic pumps and pump D as an air-pump. The pump D is used for forcing water into the accumulator E, and pump D is used forforcing water at a higher pressure into the accumulator E, while pump D is designed to force compressed air into both of the said accumulators. The accumulators EE are connected by the cock G and are constructed to sustain the necessary pressure. The accumulators have each a large connecting-chamber E from which extend the closed cylindrical chambers E or their equivalent. The pumps D D are respectively connected by conduit-pipes D and D with the accumulators E and E, and water under pressure is conducted, respectively, from these accumulators to the cylinders C and 0 through the pipes E and E, which are provided with valves E E These valves admit of the water being turned on to the cylinders O 0 either from the pipes E or E so as to move the piston O by lower or higher pressure.

For providing the power to operate the compress I prefer to employ accumulators combining air and hydraulic pressure. The accumulators E E are'used in order that the pumps may continuously work while the bale is being tied, thus accumulating pressure by compressing the air in the accumulators, which makes it possible to expedite the operation of compressing a bale.

When operating my compress, pumps D, D, and D may be driven by st a n obtained from any source or by any other power-motor, the pumps D and I) being preferably kept constantly at work, while pump D is operated only sufficiently to keep up the necessary supply of air. The valves E E and F having been closed, an uncompressed bale is introduced into the opening 0 between the compressing-platens O O and resting on the grid or fingers J in place. The valve E is then opened, introducing the lower pressure behind the pistons 0 causing them to draw forward the stirrup O and thereby close platen 0 upon platen C longitudinally, thus reducing the bale, so that when the valve E is opened and the higher pressure is introduced behind the pistons C the movable platen O is by the stirrup C drawn closer to the stationary platen 0 and the bale compressed to the desired maximum. The bale beingwhile in this position securelybound,the

valve E is closed, and the dischargewal-ve F opened to permit of the discharge of the water from the cylinders O C, steam may be intro- 'duced into the cylinder I or any other power applied to piston C to force the pistons C and stirrup back to their normal position, the water from the cylinders C C flowing back into the tank I The compressed bale being thus released is lowered by the grid or fingers J below the bottom of the car-bed, and by swinging the supporting-arm J 2 into a position at right angles to its former position the compressed bale may be discharged and the operation be repeated.
