COTTON QOMPRESSOR.

$PEGIFIGATION forming part of Letters Patent No. 704,998, dated July 15, 1902.

Application filed April 25,1902. Serial No. 104,707. (No model.)

To all whom it may concern.-

Be it known that I, FRANK L. WHITE, a citizen of the United States, residing at Pine Bluff, in the county of Jefierson and State of Arkansas, have invented new and useful Improvements in Cotton-Compressors, of which the following is a specification.

My invention relates to improvements in cotton-compressorsgand the object of the same is to construct a device of this character which will give a very high degree of compression with small expenditure of steampower.

The novel construction employed by me in I5 carrying out my invention is fully described in this specification and claimed, and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is a front elevation of my press with the plunger part way down. Fig. 2 is a longitudinal section of the same with plunger up. Fig. 3 is a side elevation of the same. Fig. 4 is a detail of the rack-bars and pistonro Like numerals of reference designate like parts in the different views of the drawings.

The numeral 1 designates a base for supporting my compressor, and footed thereon v are standards 2, surmounted by pillow-blocks 3o 3.

and bears ears 7 to which are pivoted paralv lel link-bars 8, which are oppositely pivoted to one member 9 of a pair of toggles 9.

' The member 9 is pivoted to aknuckle 10, formed integral with the pillow-blocks 3, by a cross-bolt 3. The other member of each of the pairs of toggles 9 is designated 9 and is pivoted to ears 11, formed on a head 12,

carried by the upper end of'a rack-bar 13,

which extends down and through an aperture in the base 1. A roller 14: is mounted in boxes 15 and bears against the smooth back of the rack-bar 13, and a pinion 16 is mounted in boxes 1'? and is located to mesh with the rack. 13. Brace-rods 18 are conmounted between said guides,

nected to the cross-bolts 3 and to the outer ends of the spindles 14E of the roller 14 and of the shaft 19, which carries the pinion 16. Gears 20 are keyed on the shaft 19 and mesh 5 5 with rack-bars 21,'mountedin guides 22, supported on the base 1. The racks 21 are connected by a cross-bar 22, which is connected to a piston-rod 23, which fits a cylinder 24, constructed to be connected to some source of steam-power. (Not shown.)

Guides 25, footed on the base 1, engage pins 26, seated in the rack-bar 13, and thereby hold the rack in line.

In operation a bale of cotton is placedon the plunger 7, and steam is turned into the cylinder 2 1 and the rack-bar 13 actuated to raise the plunger, through the medium of the toggles 9, to compress the bale. When the plunger has reached its uppermost position, the links 8 and toggle members 9 are vertical and parallel to the guides 4, while the toggle members 9 are horizontal and extend at right angles to the reactive force on the plunger. By this arrangement the plunger is locked, and there is no downward thrust on the rackbar 13, all the force being carried by the blocks 3.

I do not wish to be limited as to details of construction, as these may be modifred in many particulars without departing from the spirit of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is 5 1. In a cotton-compress, the combination of parallel guides, a head-block mounted intermediate said guides, a plunger slidingly knuckles mountedintermediate said guides, arack-bar, o toggles pivoted to said rack-bar and said knuckles, link-bars pivoted to said plunger and to one member of said toggles interme diate the ends of said member, a shaft hearing a pinion located to mesh with said rackbar, a pair of pinions keyed on said shaft, parallel racks meshing with said pair of pinions and connected by a cross-bar, guides for said racks, and a cylinder provided with a piston connected to said cross-bar, substan- I00 tially as described.

2. In a cotton-compress, the combination of a plunger, a rack-bar, means for connecting said plunger and said rack-bar, a pinion engaging said rack-bar, a roller mounted to bear on said rack to hold it in engagement with said pinion, gears mounted to turn in unison with said pinion, racks engaging said gears, and a cylinder bearing a piston connected to said last-mentioned racks, substantially as described.

. 3. In a compress, the combination with a base, guides mounted on said base, a plunger slidingly mounted in said guides, aracka roller keyed on said shaft and bearing on the back of said rack, a shaft bearing a gear meshing with said rack, a rack meshing with said gear, means for driving said rack to operate said plunger, diagonal brace-rods connected to the outer ends of said shafts and to said base, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
