BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 711,097, dated October 14, 1902. Application ined June 10,1902. sentira. 110,975. (No model.)

To all whom, it may concern:

Be it known that I, EDGAR BYARS, a citizen of the United States, residing at Rhome, Texasflhave invented a new and Improved Ealing-Press, of which the following is a speci'- ication.

This invention relates to a press for inaking cylindrical bales of cotton or other fibrous material; and the object is to construct a press particularly for baling cotton as the cotton comes from a condenser in a sheet or bat and which is strong and capable of adding powerful pressure to the bale as the bale increases in size, and which is comparatively light, and which is practicahand which may be constructed at comparatively small cost.

Other objects and advantages will be fully explained in the following description and more particularly pointed out in the claims.

Reference is had tothe accompanying drawings, which form a part of this specification and application.

Similaicharacters of reference are used to indicatethe same parts throughout the several Views.

The frame of this press is constructed of iron beams, preferably I-beams. Uprights 1 are mounted on sills 2 and secured thereto in any suitable manner, the drawings showthe 'uprights and to the sills.

ing cleats or tie-bars 3, which are bolted to the uprights and to the sills. The uprights 1 and the sills 2 are further connected and braced by the braces 4, which are bolted to One compression-roller 5 is stationarily mounted in bearing-blocks 37, which are mounted between and attached to the .uprights 1. Compression-rollers 6 and 7 are mounted in movable bearings, so that these rollers will yield and allow the bale to increase in size until the bale is completed. A yoke comprising a horizontal beam 8 and upright extensions 9 and 10 is provided for controlling the yielding motion of the rollers 6 and 7. The yoke is provided with horizontal arms 11 at the top parts of the extensions 9 and 10. '[he links 12 are pivotally connected to the arms 11. Bearings 13 are mounted on the shafts 14,and the links or arms 12 engage the bearings 13. The compression-rollers 6 and 7 are thus journaled in the bearings 13. The links or arms 15, which are journaled on the shafts 16, also engage the bearings 13 in the mannershown. Shafts 16 are provided with bearings 17 and 1S, the bearings 17 being bolted to the sill 19 and the bearings 1S being bolted tothe sills 2. Consequently the shafts 16 are journaled in stationary bearings. The movement of the yoke 8 is controlled by hydraulic power. This yoke has enlarged portion 20, which constitutes a socket for the piston-rod 2l, which engages a piston-head 22 in the hydraulic cylinder 23. The cylinder 23 is supported on the sill 24, which must rest on some solid support. The sill 24 is tied to the sills 2 by braces 25, which pass beneath the sill24 and then upward and are bolted to the sills, as shown. The braces 25 are themselves braced from the top part of the sill 24 by means of the tiebars 26, which are bolted to the braces 25 andto the sill 24, one at each end. The hydraulic cylinder 23 sits on the sill 24. A second cylinder 28 is provided for the retreat of the Water from the cylinder 23. The liquid passes from the cylinder 23 through a pipe 29, which is provided with a safety-Valve 3l). The valve 30 is con-A trolled by the weight 31, which is mounted on the lever 32. The lever 32' is provided IOO with a fulcrum 33 and has a lug 34, which presses on the valve 30. The liquld is forced back from the cylinder 28 through a pipe 35, which is provided with a check-valve 36, to

the cylinder 23, the check-valve being pro- 28 into cylinder 23 by means of steam or comis provided with suitable packing 43.

pressed air. i A valve-box 38 is mounted on and attached securely to the cylinder 28 by bolts 39, which engage the ears 40 of the valve-box. A valve 41 is mounted in the box 38 and is provided with a valve-stem 42, which This valve 41 is adapted to open and close the intake-port 44 for the cylinder 28 and to open and close the exhaust 45 of the valve-box 38. Steam or compressed air may be admitted to th-e box 38 through the aperture 46.

The means for operating the valve 41 consist of alever 47, pivotally mounted on a shaft 48, which serves as a fulcrum for the lever, the stem 42, pivotally connected to the short arm of the lever 47, the lug 49, carried by the stem 42, and a spiral spring 50, set on the lug 49 and pressing against the under side of the lever 47 beneath the shaft 48. The spring 50 causes the valve 41 to stand normally With the exhaust open. When the lever 47 is depressed, the exhaust is closed and the steamintake is opened. The dropping of the bale out of the press will have this eect. The

shaft 48 is supported in bearings 51, which are attached to the sills 2, or the shaft might extend through said sills.

Power for driving or rotating the compression-rollers may be applied to shaft 52. This shaftisjournalediu bearings 53 and 54, which are bolted to the under side of sills 2 and 19. A sprocket-wheel 55 is mounted on shaft'52 and drivesa sprocket-chain 56, and this chain drives the sprocket-wheel 57. The sprocketwheel 57 is mounted on shaft 58. This shaft is journaled in the bearing-blocks 37. These blocks have elongated bearings for the shaft to take too great strain from the shaft 58. The bolts 59 pass through theblocks 37 and the uprights 1, and the braces 4 are bolted to uprights l. y.A cog-wheel 60 is provided for driving each of the shafts 14 of the compressionrollers 6 and 7. The wheels 60 are driven by thecog-wheels 61, which are mounted on the shafts 16. The wheels 6l are driven by the cog-wheel 62, which is mounted on shaft 52. Driving the shaft 52 will rotate the compression-rollers.

ward motion of the yoke 8 as that yoke is forced down by the forming bale and for replacing the compression-rollers after a bale drops from the press.

The compression-roller 5 being mounted in stationary bearings, which are attached between and to the upper parts of uprights 1, the compression rollers 6 and 7 must be mounted in yieldingbearings. The bale is formed beneath the roller 5, the bale being pressed down against the rollers 6 and 7. As the bale increases in size (the cotton being fed to the compression-rollers in any suitable manner) the rollers 6 and 7 must yield to the increasing bale and in yielding force the yoke 8 down by reason of the bearings for the rollers 6 and 7 being pivotally connected to arms of said yoke. The arms 11 are formed on the extensions 9 and 10,which extend from the outer horizontal parts of the yoke up between the ends ofthe compression-rollers and the frame-pieces or uprights `1. Guides 66 are placed on the arms 11 to give the arms 11 steady up and down movement. The downward motion of this yoke is resisted bythe liquid in the hydraulic cylinder, this yoke engaging the piston-rod of the piston in said cylinder, and by the spiral springs 65, or by the hydraulic pressure alone. The bearings for rollers 6 and 7 are pivotally engaged by the links 15, which are pivotally mounted on the shafts 16, and these shafts are bound to the sills of the press by .reason of the bearings 17. The compression-rollers 6 and 7 must yield Outward and downward, and in order to do this they have to force the yoke 8 downward. This operation goes on until the center of the bale becomes even with lines run longitudinally through the center of the compression-rollers 6 and 7, wheny the bale drops from the press. When the bale drops from the press, the lever 47 isv depressed.'

This closes the exhaust 45 and turns steam into the cylinder 28. The steam will force the liquid,which has retreated in the cylinder 28 during the formation of the bale, back into the cylinder 23 and raise the piston, and so force the yoke back to-starting position to replace the rollers for commencing a new bale. The springs aid in replacing the rollers. The rollers might be replaced by the spring alone, or they might be replaced by the steam and liquid, as described. The arms 11 in their upward and downward motion are guided and held in place by the guides 66, which project out and engage loosely the upright beams 1, as shown in Fig. 3. The spiral spring operates between a collar 67 and the cylinder-head.

Various changes may be made in the construction of this press without departing from my invention. Instead of the arms 11 a simple bearing 11', in which arms 12', similar to arms 12, may be pivotally connected, as shown in Fig. 5, and instead of two uprights l one upright 1' may be used and a bearing 37 for each side of the press formed in the upper part of the upright 1 for the shaft 58.

A guide 66 would be attached to each upright extension E) and 10 for engaging the uprights 1', as shown.
