HAY AND COTTON PRESS.

SPECIFICATION forming part of Letters Patent No. 286,619, dated October 16, 1883,

Application filed September 1, 1883. (No model.)

or more screws, similar to that described in Letters Patent granted to WV. J. F. Liddell, April 8, 1879, No. 214,046, and February 20,

.1883, No. 272,719; and it consists in thecombination, with the bevel-wheel shaft, through which motion is imparted to the plunger, of a second bevel-gear, through which increased speed may be imparted to said shaft, and the plunger for retracting the latter, after compressing a bale, by an arrangement of friction wheels or gears connecting said bevel-wheel shaft with the first or driving shaft in means for automatically. throwing the retracted mechanism out of action when the plunger has completed its retractive or imperative throw;

1 and in a novel construction of clutch-lever,

whereby its friction upon the grooved collar of the clutch or, gear sleeve is diminished, as hereinafter explained.

It further consists in a packing mechanism for packing the material in the presschamber preparatory to compressing said material into a bale therein.

In the accompanying drawings, Figure 1 represents a side elevation of our improved press. Fig. 2 represents a horizontal section taken on the line a: m, Fig. 1; and Fig. 3, a similar section taken on the line g 1 Fig. 4 represents a vertical section taken on the line 2 2, Fig. 3. Fig. 5 is a' similar section through the gearblock and gearing, taken in line with the central upright bevel-wheel shaft; and Fig. 6 is a detailed view, showing a modification in the swiveling loop connecting the shipping-lever fork with the clutchsleeve.

The construction of the frame of the press and the arrangement of the movable platen or plunger and of the screws and gear-nuts for actuating said plunger are similar to those of the patents referred to, and said parts will not therefore be described herein in detail further than is necessary to an understanding of our present improvement.

A and A represent the corner posts and horizontal connectingtimbers of the upright pressframe; B, the fixed and Bthe movable platen; C and G the endwise moving screws for actuating the platenB; D and D, the geared nuts for actuating said screws, and D the interposed pinion or gear-wheel, through which motion is imparted to the gear-nutsD and D, said gear-nuts and pinion being journaled in a gear block or plate, E. The gear D has formed upon or secured to its upper face, or to the upper end of the shaft a, with which said gear is connected, a bevel-wheel, Dflwith which bevel-pinions f and f on the main driving-shaft, F, on opposite sides of shaft a, engage. Pinionsf and f are loose on the shaft F, and the latter, between said pinions, is squared or feathered and has a clutch-sleeve, F, upon it, adapted to slide endwise on the shaft, for coupling either of the pinions f and f to .the shaft and actuating the bevel-wheel D according to the direction in which it is de= sired to move the latter and the platen or plunger B; or it may be moved to an intermediate position, for disengaging b oth pinions and throwing the machine out of gear.

. The shaft a extends through and below the gear-block E, and has a bevel-pinion or miter-wheel, a, fast on its lower end, which engages a corresponding gear, a}, fast on a transverse shaft, b, journaled in pendent lugs or brackets attached to the gear-block. One of these bearing-brackets, e, is rigidly secured to saidblock, while the other, e", is secured to alever, e pivoted near the center of its length to said block, one end extending forward to within convenient reach of the attendant, and the other carrrying an adjustable angular foot, '6 for a purpose which will appear. The end of the shaft b projecting outside of the bearingbraoket c has a friction-wheel, 1), upon it, which,by the adjustment of lever e, is adapted to be niovedinto or out of frictional engage ment with a corresponding wheel, 1)", fast on the first or main driving-shaft F. The wheels b and V, as also the gears a and a are by preference made those of each pair of equal ICO diameter, in such manner that, when the shaft a ,with its pinion D are geared through them to and driven by them from the first or main driving-shaft F, the speed of the shaft a will be equal to that of shaft F, and will serve to rapidlywithdraw orretractthemovableplaten. The lever e is actuated by the attendant for moving the wheel 2) into engagement with wheel I), andis automatically operated for moving said wheel I) out of engagement, just as the movable platen completes its outward or imperative movement, by means of a pendent arm or foot, B attached to one corner of said platen or plunger, and which comes in 0011- tact with the angle-iron or foot 0 on the end of lever e, depressing the latter and with it thewheel W. The angle-iron or foot chas a vertical slot formed in its vertical portion, and is secured by a set-screw to the end of lever 6 for permitting its adjustment and varying the point at which the descending plunger shall terminate its downward throw. When the gears a, a, b, and b are not employed for retracting the plunger, and the latter movement is effected through the pinions f and f, the following arrangement of parts serves to automatically throw the retracting mechanism out of gear as the plunger completes its downward or imperative throw:

The clutch-sleeve 1? has a grooved collar, y, with which the fork g of a shipping-lever engages for adapting the clutch-sleeve to be moved endwise on the shaft F. The fork gis provided with an inner fork or ring, 9, connected by pins with the fork g of the leverin such manner as to adapt it to swing in its bearings in said fork to conform itself to the groove in the sleeve under the varying angles of the latter to said groove, thereby obviating to a great extent the friction due to the employment of the fork as ordinarily applied. The inner swiveling fork or loop, may be made either in the form of a halfring, or it maybe made in two parts united by flanges or feet at the ends, as shown in Fig, 6, and so bemade to surround the sleeve, if desired, without interfering with its free rotation. The outer end of the lever G passes through a notch or perforation in a bar, H, sliding h0rizontally in loop-brackets h, attached to the corner posts at one side of the frame, and provided on'its inner face with spur h, through which the bar H is moved laterally for acting on the lever G and the clutch-sleeve F, as follows:

In the upper end of a suitable standardbracket, I, secured to one end of the gearblock, is mounted a rock-shaft, 1', provided on its inner end with a crank-arm, t, which reaches upward in an inclined position, adapting it to be acted upon by an arm or bracket, 0, attached to the lower side of the plunger in such manner that as the latter nears the end of its down ward throw the bracket 0 comes in contact with the arm 1', depressing it and rocking the shaft i in its bearings in the bracket I. The

outer end of the shaft i has attachedto it an arm, 2' which extends upward in position to act upon the spur h in such manner that as the arm 1 is vibrated downward the bar H will be moved laterally, carrying with it the arm of the lever G, attached thereto, and withdrawing the clutch-sleeve F from engagement with the pinion f or f, whichever may be acting to depress the plunger. The arm 1' may be forked or slotted to embrace the spur h, if preferred, and the crank -ShELfi'/7:'1'i12ty have the end to which the crank i is attached squared to match a corresponding socket in the crank-arm, for permitting the latter to be applied, inclining on either side from an upright or vertical position, according to the direction of movement of the main driving-shaft actuating the press, it being convenient to be able to drive said shaft sometimesin one direction and sometimes in a reverse direction. The spur h passes through a horizontal slot in the bar H, and is connected with said bar, a thumb-nut or equivalent device permitting the lateral adjustment of the spur, as may be required to suit the di reetion of rotation referred to and to compensate for wear of the parts.

To the upper transverse bar, A at one side or end of the press-frame proper, is secured one end of a horizontal bar, K, forming a sup-' port and horizontal track for a roller in the upper end of a loop, 70, through which one end of the upper platen, B, is suspended from said bar K. The. other end of said platen is suspended from the upper front and rear frametimbers by angle-irons secured at their lower ends to said platen, and having inwardly-projecting horizontal arms at their upper ends, provided with rollers which rest and roll on said frame-timbers. By this arrangement the platen B can be moved over the press-chamber or be run off to one side, for facilitating the filling of the latter. The outer end of the rail or track-bar K is supported by a bracerod, 76*, extending obliquely downward there to, from the upper end of a packer-frame supported above the press-chamber upon the upper press-frame timbers. This packer-frame is composed of corner uprights, L and L, secured at their lower ends to the upper horizontal press-frame timbers, which are thereby made to serve as'a lower horizontal frame for the packers, and at their upper ends the uprights L and L are united to a similar rectangular frame, L Within the frame L L is arranged a second upright frame, M, corresponding in external measurement in hori' zontal section to the internal measurement of the frame L L, within which said frame M is adapted to slide vertically, and also with that of the press-chamber beneath it. The frame for the frame M, and may be of any suitable construction for that purpose, and the frame M, which is designed for packing the material to be operated upon in the press-chamber until a sufficient amount is contained therein to IIO L L is designed as a guideway and support form a bale, may also be of any suitable construction adapting it to move easily on ways in the frame L L. It is shown composed of end uprights united at'their upper ends to horizontal bars M, and at their lower ends to similar bars or a plate, M which serves as a piston or packing-head for packing the material operated upon into the bailing-chamber. To the end bars, M M or to a central upright, M", secured to said end bars, is'attached a vertical rack, m, which engages with the teeth of a pinion, n, loose on a horizontal shaft, N, mounted in bearings on the upper pressframe timbers. The shaft N has a squared or feathered portion adjacentto the pinion n, and upon said portion is a sliding clutchsleeve, 71 for connecting said pinion with or releasing it from its shaft.

In suitable bearings in the upper press-frame timbers is mounted a rockshaft, P, arranged at right angles to and below the shaft N, and provided with an angular fork or crank-arms, 1) 19, between the upper ends of which is pivoted an inner fork or loop, p, similar to 9, above described, arranged within a groove in a collar of clutch-sleeve if, the arrangement being such that the attendant, by rocking the shaft 1?, can move the clutch-sleeve into or out of engagement with the pinion a, for coupling thelatter to or releasing it from its shaft N. The pinion n has a ratel1et-disk,n', formed upon. or secured to it with which a pawl, 7-, on a weighted lever, B, engages, for holding the pinion, and with it the rack in and pistonframe M, at any desired adjustment. One arm or lever, B, extends outward into convenient position to be actuated by the attendant for releasing the ratchet-disk and pinion, which, when the latter is released from the shaft N, leaves the frame M free to fall upon the material in the press-chamber, for packing said material therein. The shaft N has upon one end a spur-gear, N, which engages with and is driven by a pinion, S, on one end of ashaft,

' S, arranged by the side of shaft N in bearings on the upper press-frame timbers, and provided on its opposite end with a crank for actuating it, or with a band-wheel, S", to which motion may be imparted from a band-wheel on the first or main drivingshaft of the press, or other convenient driving-shaft, for actuating the shaft N and raising the piston or packer M. By this arrangement the packer can be readily raised by the pinion a with its shaft, and, when raised .to the desired height, will be held by the pawl 1-, with the pinion it released from its shaft, until itis desired to pack the loose'material' in the baling-chamher, when by lifting pawl r the packing-piston M drops by its own'gravity upon said material. The operation can be repeated until the amount of material required for the bale is packed in said chamber, when the packer is run up out of the way, the platen B moved into place under it and over the baling-chamber, and the material in said chamber is then compressed and formed into a bale in a manner well understood. A safety pin (indicated at t) is passed through a perforation in the frame-timber, and engages the packerframc, for preventing the latter from falling accidentally when not in use.

Parts of the press not particularly described may be constructed and arranged as described in the patents referred to, or in any usual or preferred way.

Having now described our invention, we claim as new- 1. The shaft of the central bevel-wheel and pinion, through which motion is imparted to the screws actuating the movable platen or plunger, extended below the gear-block, in which it has its bearings, and provided with a second gear, in combination with gearing connecting said gear with the main or first driving-shaft, substantially as and for the purpose described.

2. The combination, with the central bevelwheel and pinion-shaft and the gear-nuts and screws for actuating the movable platen, of the second bevel-gear, a, the shaft b, provided with the pinion ai and the friction -wl1eel thereon, adapted to be moved into or out of engagement with a friction-wheel on the drive ing-shaft, substantially as and for the purpose described.

3. The central bevel wheel and pinionshaft, with the gear-nuts and screws for actuating the movable platen, in combination with an adjustable shaft geared to said central shaft, and provided with a friction or gear wheel engaging a similar wheel on the drivingshaft, and means connected with the movable platen for automatically throwing said wheels out of engagement as the platen or plunger completes its retractive or inoperative throw, substantially as described.

4. The combination, in a baling-pr'ess, of

the sliding clutch-sleeve with itsgrooved collar, the shipping fork or lever, and the sw1velin g loop or ring connecting said sleeve and lever, substantially as described.

5. The combination, with the hipping fork or lever for throwing the press-gearing into and out of action, of the sliding bar H, with its spur, and the rock-shaft c, with its crankarm and lever for actuating said sliding bar and shipping-lever, adapted to be operated by the moving plunger or platen for throwing the press mechanism out of gear, substantially as described.

6. The sliding packer moving in a suitable frame or ways above the bailing-chamber, in combination with mechanism, substantially as described, for lifting said packer, and means for releasing the same and allowing it to descend upon the material in the baling-chamber for packing said material therein, substantially as described.

7. The combination, with a baling-press, of a packing-piston provided with a rack, on, a

pinion engaging with said rack for actuating moving in ways therein for packing the material operated upon in the balingchamber, and the stationary platen suspended underneath said packer-frame and adjustable laterally on Ways connected therewith, substantially as described.
