SPECIFICATION forming part of Letters Patent No. 585,300, dated June 29, 1897.

Application filed April 30, 1896. Serial No. 589,767. (No model.)

T all whom it may concern.-

Be it known that SAMUEL Z. HALL, deceased, late of Little Rock, in the county of Pulaski and State of Arkansas, did invent certain new and useful Improvements in Gotton-Presses, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in cotton-presses, the object of the invention being to so construct a cotton-press that ade quate force can be applied to compress the cotton with the expenditure of a minimum amount of driving power.

A further object is to construct a cottonpress in such manner that the bale-chamber can be made comparatively short and so that the operating mechanism can be located under the baling-chamber and receiving-box.

A further object is to improve the construction of baling-presses in various respects and to so construct the apparatus that it shall be comparatively simple, not easy to get out of order, and so that it shall be effectual in all respects in the performance of its functions.

IVith these objects in view the invention consists in certain novel features of construction and combinations and arrangements of 0 parts, as hereinafter set forth, and pointed.

out in the claims.

In the accompanying drawings, Figure 1 is a view of a cotton-press embodying the improvements. Fig. 2 is a view in cross-section.

Fig. 3 is a detail View.

A represents a vertical frame comprising a base 1, a crosshead 2, vertical timbers 3, tierods 4:, and suitable braces or cross-bars.

Immediately below the cross-head 2 a bal- 4o ing-chamber 5 is located and provided with slotted doors 6 to permit the removal of the pressed bale of cotton. The doors 6 of the baling-chamber are held rigidly closed during the operation of pressing the cotton therein by means of hooks or hooked rods 7 8, respectively. Two such hooks are preferably provided for each door 6, and the inner end of each hook orhooked rod is pivotally connected to a transverse rod a, disposed centrally over the baling-chamben Under each pair of hooks or hooked rods a shaft 9 is mounted in suitable bearings 10, and each rod is provided at one end with an arm or lever 11 by means of which to turn it. Cams 12 are secured to the shafts 9 (one cam under each hook or hooked rod) and are adapted, when the shaft is turned, to engage the hooks or hooked rods and lift them, so as to release the doors of the baling-chamber.

At the base of the baling-chamber dogs 13 are pivoted and project through the slots in the doors 6, said dogs being adapted to prevent cotton forced into said chamber from falling, as hereinafter more fully explained.

Below the baling-chamber the receivingbox 14 is located and provided with an opening through which the cotton can be inserted into said box, and said opening is closed during the operation of pressing the cotton in the. baling-chamber by means of a door 15.

Bars or arms 16 project outwardly from the frame of the machine, and between these bars or arms a frame 17 is pivotally connected and constitutes in effect a lever. The frame or lever 17 is connected with the door 15 by means of toggle-levers 18. By means of this frame or lever and its connections with the door 15 said door can be opened to permit the insertion of cotton into the receiving-box and tightly closed during the operation of compressing the cotton in the baling-chamber.

A shaft 19 is mounted on the base of the frame, and on this shaft two pulleys 20 21 are mounted. A straight belt may be made to transmit motion from any convenient source 8 5 of power to one of said pulleys, and a crossed belt will be passed about the other pulley. The pulleys 2O 21 are normally loose on the shaft 19, but can be locked alternately therewith by means of a double clutch 23, located between them. By shifting this clutch motion can be transmitted to the shaft by one or the other of the driving-belts in one or the other direction. The shaft 19 is provided at one end with a pinion 24, which meshes with 5 and transmits motion to a gear-wheel 25, secured to a shaft 26. The shaft 26 is provided at points near its ends with worms 27, adapted to transmit motion to two large wormwheels 28 28. Pitmen 29 29 are pivotally con- 10o nected at one end to the worm-wheels 28 at points near the peripheries of the latter, and the other ends of said pitmen are pivotally connected with the plunger 30 of thepress.

In order that the plunger may move freely and without binding, it is provided with guide-rollers 81, having grooved peripheries, and these guide rollers run on \l-shaped guides 32.

A lever is pivoted at a point between its ends to the framework and passes between lugs 34:, projecting laterally from a longitudinally-movable. bar 35. The lower end of the lever 33 is connected with the clutch 23 and its upper end is pivotally connected to a movable rod or bar 36. To one end of the rod or bar 36 a pivoted operating-lever 37 is pivoted.

The shaft of one of the wormwheels is provided with a tripping device consisting of arms 38, which at the ends of the movement of the plunger are adapted to engage a lug 39, projecting from the bar 35.

From the construction and arrangement of parts above described it will be seen that when motion is imparted in one direction to the worm-shaft by means of the gearing above explained motion will be imparted to the worm- Wheels and cause them to make a partial revolution, during which the plunger will be moved upwardly by the pitmen 20 and cause the cotton introduced into the cotton-receiving box to be compressed in the baling-chamber, from which latter the cotton will be prevented from falling back into the receivingbOX by means of the dogs 13 while the plunger is being returned and another charge of cotton is being placed in the receiving-box.

\Vhen the plunger completes its upward movement, one of the arms 38 will engage the lug 39 on the bar 35 and move said bar longitudinally, thus causing one of the lugs Sit on said bar to engage the lever and move the same on its fulcrum, resulting in moving the clutch to throw the driving mechanism out of gear. The hand-lever 3'7 may now be operated to further move the clutch and lock the opposite pulley 21 to the shaft 19, whereupon the worm-wheels will be made to turn in the opposite direction to that above described and result in returning the plunger. As the plunger reaches the lower end of its movement one of the arms 38 will engage the lug 39 on bar 35 and move the latter, whereby to cause a movement of the lever 33 and the driving mechanism to beagain thrown out. of gear.' Another charge of cotton having been placed in the receiving-box the above operations will be continued until a bale of the proper size and amount of cotton shall have been completed.

. The worm-wheels will each be provided the crank-pins of the pitmen, so that when said worm-wheels become worn or a tooth or teeth become broken the connection of the pitman or pitmen with the worm wheel or wheels can be changed and thus present unused teeth of said worm wheel or wheels to the worms.

It will be observed that the operating mechanism is located at the bottom of the apparatus, thus avoiding making the press unsteady and top-heavy, as would be the case if the mechanism were located on top of the press.

The improvements are simple in construction, can be effectually actuated with the expenditure of a minimum amount of driving power, and are eiiicient in all respects in the performance of their functions.

Various slight changes might be made in the details of construction of the invention without departing from the spirit thereof or limiting its scope, and hence do not wish to be limited to the precise details of construction herein set forth; but,

Having fully described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. In a baling-press, the combination with a plunger, of two wheels, pitmen connected to said wheels and to the plunger, whereby a partial revolution of said wheels will cause a complete movement of said plunger, and means of transmitting motion to said wheels simultaneously, said wheels having a multiplicity of sockets located on different radii adjacent to the periphery of the wheels, for the attachment of the pitmen whereby different sets of the teeth may be shifted into position to be engaged by the worms, substantially as set forth.

2. In a baling-press, the combination with suitable framework, of a baling-chamber having doors, a rod over the baling-chamber, hooks pivotally connected to said rod and adapted to engage said doors to retain them closed, shafts under said hooks, cams on said shafts to engage the hooks to raise them when the shafts are turned, and operating-arms for said shafts, substantially as set forth.
