MACHINERY FOR PRESSING COTTON SPECIFICATION forming part of Letter s Patent No. 451,846, dated May 5,1891.-

Application filed September 2,1890. Serial No. 363,753. (No model.)

To aZZ whom it mrt'y concern:

Be it known that I, J. A. BAOHMAN, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Machinery for Pressing Cotton; 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. My present invention is an improvement in machinery for facilitating the pressing of cotton; and it relates particularly to mechan-.

ism in which cylinders and pistons are used, fluid o'i-'1iquid-'si'ich as steam, air, water, or gas under pressure-to operate the follower-block of a baling-press.

In my device I employ a compound cylinder-that is, a cylinder made up of two cylinders of different sizes or diameters, each having its own piston and both fixed about a single piston-rod.

The object of my invention is to produce a press of great and increasing power, economically arranged, that will press cotton quickly and well.

V In the drawings illustrating my invention, Figure 1 is a vertical sectional view of the lower-block shown in elevation. Fig. 2 is a similar view showing the pistons and follower- In the drawings similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, A is the followerforming a part of the piston-rod ll, arranged to move vertically. The piston-rod B has fixed upon it two pistons-C a small one, and D a large one. The cylinder in which said pistons move is composed of parts E and F. The closed bottom of this cylinder has enterto convey air, watcr,or whatever may be used as a medium in lifting the follower-blockA. Through the upper head I: of the compound cylinder passes the piston-rod B. Near thebottom of the piston-rod 13 istightly secured a collar (1, provided with a dowmvardly-pro steam is exhausted from the cylinder, thro jectiug lip e, to engage the catch of a lever,

larger of the two pistons. A packing-ring f is fixed on the said piston-rod near the collar (Z, and-between it and said collar are interposed spiral springs g. The large piston D encircles thepiston-rod B with a tight joint, though they are not'secured gethcr. livoted permanently toabove them,are U-shaped levers H, with hooks or catches e' and arms e. The purpose of these levers andcatches is to lock the piston D to the piston rod or shaft, so that the lifting influence exerted on'the said pishereinafter to he described, pivoted to the to the piston D, or hoods provided ton may be communicated to the follower A throughthepiston-rod. The U-shaped levers and their hooks or catches are arrange w1tl 1- in the piston D, and all joints incident to their arrangement are to be made tight by sui able acking. I

In the operation of my press mechanism the steam, liquid, or fluid used as a medium for power enters the cylinder through pipe a below the piston c, exerts a pressure upon said piston; and and follower-block upward until the collar (1 reaches the larger piston D, the rod B passing freely through said piston D in its up- 'ard movement, The paoking'ring f at this juncture rests in the recess of the said piston I), the springs g having been compressed by the weight of the same. As soon as a solid bearing is reached the piston D will be lifted upward in the continued movement of the iston-rod 1;. It is obvious that as soon as the piston 0 has passed into the larger part of the compound cflinder-theforce will be exerted upon the under surface of the larger piston T), thus greatly increasing the ower at a period in the movement of the fol owerblock when the greatest pressure is required.

forces it with the piston-rod After the stroke is complete and the follow-.

be lowered the fluid, liquid, or fshthe pipe whence it came, (a proper valve to effect this return. being provided,) and the said block, piston, and piston-rod gravitate to the points and positions whence they started. Thou-shaped levers ll, when lifted with piston D by gravity, automatically take oner-block is to to the lips of the collar d-as soon as the larger piston begins to rise, and when said piston returns to its sent the arms bear upon the offset 7; of the cylinder E to release the entehes "i from the said collar (1.

Having thus described my invention, What I claim as new, and wish to secure by Letters Patent, is v 1. The compound cylinder adapted for one steam or compressed-air supply, composed of two cylinders of different diameters united as one by an annular shoulder, in combiner tion with the pistons of different sizes to suit seicl cylinder, the larger arranged to admit of a free movement of the piston-rotl through it end the sinnllerfixetl to said roll, and the piston-rod described, siihstantinlly as set forth.

2. in mechanism for pressing cotton and analog ens substances, the combination, with the follower-block, the piston-rod provided with eollers and paeking-rings described, and the two pistons, of the compound cylinder composed of two cylinders united as one by an annular plate or shoulder, as set forth.

3. The combination, with the cylinders of different diameters, as clesoribed,an l the piston-rorl and pistons, of the levers H, pivoted above the larger piston, the arms of which are adapted to bear on the horizontal wall or plate formins the junction of the two parts of the compound cylinder normally, and the inlet-pipe, as and for the purpose set forth.

In testimony whereof I am): mysignatnre in presence of two witnesses.
