' Application iiledSeptember 27, 1900. Serial No. 31,281. (No model.)

To all whom, it muy concern:

Be it known that I, MILTON BRANARD JONES, acitizen of the United States, residing at Meridian, in the county of Lauderdale and State of Mississippi, have'invented a new and useful BalingPress,`of which the following is a specification. l

This invention relates to balingpresses,` and has special reference to that type of plu nger-presses adapted for the baling of hay, straw, and other material.

The main object of the invention is to ef-: t

fect certain improvements' in that type ofj plunger baling-presses commonly known as the rebounding plunger-press, involving? the employment of a plunger which has a powerful forward movement limparted thereto and which may easily rebound or return to its normal position.

To this end the invention contemplates a novel construction of power mechanism embodying simple and positive'means for thrust-' ing the plunger forward with apowerful force and to increase the power thereof in proportion to the increase in the resistance of the material being pressed-in other words, to increase the leverage exerted 'upon the plunger in its forward movement as the pressure or resistance of the material increases.

The invention also contemplates an iin-i proved power mechanism which permits the free and sharp retraction of the plunger,- while at the same time relieving the draft n w baling-chamber properwithin which the bale animal from the shock thereof.

With these and other objects in View, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination,

and arrangement of parts hereinafter more fully described,illustrated, and claimed.

While the essential features of the inveny tion are necessarily susceptible tosome modiication without departing'from the spirit or scope thereof, still the preferred embodiment of the improvements is shown in the accompanying drawings, in which- Figure Vlis a plan view of a baling-press equipped with the improvements contemplated by the present invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is a detail plan View of the rotating power-head, showing the initial relation of parts-during the forward thrust or movement of the plunger. Fig. 4 is a View similar to Eig. 3, showing a second position of the parts in whichthe plunger has started upon its rebounding movement. Fig. 5 is a similar view showing a third position, illustrating the relationA of parts when the plunger is completely retracted and the operating connection or pit- `man for' the plunger is about to 'be caught again by the power-wheel for thrusting the plunger forward.

Like numerals of reference designate corresponding parts in theseveral figures of the drawings. In carrying out the invention the improvements in the power or power mechanism may be associated with any of the ordinary types of plunger baling-presses; so for illustrative purposes there is shown in the drawings a sim- 'ple form' of press embodying a baling-chamber l, adapted to receive therein the reciprocating baling-plunger 2 and, provided in the top thereof with a feed-opening 3, at oneside of which feed-opening is arranged .a verticallymovable pressure-roller 4, yieldingly vheld depressed through the medium of holding-springs 5 and adaptedto yield upwardly as'the plunger 2 passes beneath the same to permit ofthe hay or other material being freely folded or tucked thereunder by the plunger, said roller et therefore serving, in

connection with the plunger, as a folder for the material which is compressed within the ris formed. l

While the power or power mechanism forming the essential part of the present application may be operatively related to the plunger 2 in different ways, still in the drawings there is shown the preferred way which is employed. This involves the mounting of the reciprocatory plunger 2 at one end of the reciprocating plunger@ staff 6,-arranged to work horizontally over the extendedpowerbase 7 and riding upon a bearing-roller 8, mounted within the said base and 'serving as a roller or bearing-support'for the staffv 6 to relieve the same from indue friction in the reciprocatory movements thereof. The said plunger-staff 6 is provided contiguous to the end opposite the plunger with a longitudinally-disposed slot 9 and has connected to IOO said end opposite the plunger, as at 10, one end of a retractile spring 11, the other end of which spring is iitted in an adjustable holding-plate 12, which is shown as being provided with a slot 13, receiving a clamping-bolt 14, passing through asupporting-block15,mou nted upon one end of the power-base 7. The said holding-plate 12 may be freely adjusted to regulat-e the tension of the retractile spring 11, and thereby provide means for regulating the speed and sharpness of the rebound of the plunger, and it will be understood that the spring 11 normally exerts its tension in a direction to retract the plunger out of the baling-chamber and at one side of the feed-opening 3 thereof. An antifrictionroller 15 surrounds the pivot-post 2l, hereinafter referred to, and operates within the slot S) of the plunger to obviate any tendency of the plunger to bind under the iuiiuence of the lateral pressure ot' the pitmau.

In the construction shown in the drawings the operative connection between the power or power mechanism and the plunger is effected through the medium of a swinging pitman 16, pivotally coupled at one end, by means of a rabbeted knuckle connection 17, with the plunger-staff 6 at a point intermediate the ends of the latter, the pitman 16 carrying at its opposite or unpivoted end an offset wrist-pin l8,carryi ng an antiiriction-roller 19 and adapted to cooperate with the rotating power-head 2O in the manner to be presently explained. By reason of the employment of the pitlnan connection between the powerhead and the plunger-staff the latter is given a straight forward movement, and the plunger has no tendency to sidewise movement, as when the plunger is pivoted to the end of a plunger-staff, which is the common construction in hay-presses.

The rotating power-head 20 is preferably in the form of a wheel mounted to rotateupon the stationary pivot-post 2l, secured to and arising from the base 7 and having mounted thereon the holding-collars 22 and 23, arranged, respectively, above and below the power head or wheel 2O and removably and adjustably held upon the pivot-post 2l by means of the set-screws 24, the said collars 22 providing for holding the power head or wheel 2O in the proper working position upon the pivot-post, while at the same time permitting the ready removal and replacing thereof for repair or ot her purposes. The said revoluble power head or wheel 2O has formed therein a peculiarly-shaped camway or slot 25, which by reason of the general rectangular form thereof and the different lengths of the side and end walls of the same may be described as being of an approximately oblong form with the opposite curved outer side walls 26 and the substantially straight or convexed outer end walls 27. The said camway 25 is not truly oblong in shape by reason of the fact that in diagonally opposite corners thereofthe cam head or wheel is formed with the olset thrust-notches 28, each of which notches is located at one end. of one of the end walls 27 and merges directly into said end wall, but meets the adjacent side wall 26 in an inwardly-projecting nose or point 29, lying opposite to and at one side of the plane of the adjacent hook-point 30 of the interior S-cam or sigmoidal cam-block 31, which is centered within the camway or slot and constitutes the inner wall of the said camway. By reason of its S shape the interior cam or cam-block 31 is necessarily provided with sigmoidal sides lying opposite the curved side walls 26 of the way, and at its ends the said interior cam or cam-block is formed with the aforesaid alined hook-points or concavities 30 reversely disposed opposite the offset thrustnotches 28 to receive the wrist 1S as it escapes from one of the thrust-notches.

The wrist 18 of the pitman 16 projects into the camway 25 and follows the peculiar contour or outlines thereof in the rotation of the power-head, and to provide for reinforcing the interior cam of the power-head arched braces 32 connect the points of the cam with the adjacent portions of the head or wheel and bridge the way or slot 25 to permit the wrist 18 to freely pass thereunder, said braces being illustrated in Fig. 1 of the drawings, but omitted from Figs. 3 to 5, inclusive, so that the latter figures may clearly show the different positions of the parts.

Rotary motion is imparted to the power head or wheel 20 through the medium of the sweep 33, arranged transversely across the power head or wheel 2O on top thereof at substantially right angles to the disposition of the rotary cam 30, and preferably formed in its under side with clearance-grooves 34, arranged above the side portions of the camway or slot 25, in order to permit the wrist 18 to freely pass beneath the sweep.

Assuming the power head or wheel 2O to be rotated in the direction of the arrow shown in the drawings, it willbe observed that when one of the offset thrust-notches 28 is engaged with the roller 19 of the wrist 18 the swinging pitman 16 may be said to be looselyinterlocked with the power head or wheel, so that as the latter continues to rotate the said pitman 16, together with the plunger-staff, is thrust in a forward direction. At the same time the unpivoted end of the pitman is swung inward toward the plane of the plunger-staff, so that the leverage of the power head or wheel increases as the pressure or resistance of the material being compressed by the plunger increases, thus insuring a baling of the material under great density. This gradual increase of the leverage exerted against the resistance of the material is obviously due to the fact that at the beginning of the forward movement of the plunger the pivotal connection of the pitman with the power-head moves substantially in aplane parallel to the direction of pressure` the arcuate plane through which this con- IOO IOS

nection passes effecting a continually-changing relation of the parts, so that asvthis.

pivotal connection or knuckle nears the end of its movement it is moved in a plane nearly at right angles to the directionof pressure-that is to say, a large percentage of the movement of the head is absorbed by Vthe movement of the pivotal connection in av When the thrust-notch 28 is interlocked' with the wrist 18, as shown in Fig. 3 of the drawings, which is a position about over thek plane of reciprocation of the plunger-staff, the wrist-roller 19 is necessarily caused, under the retractive inuence of the spring ll, to roll oft' of the inwardly-projecting point or nose 29 at one side of the said notch 28 andis prevented from swinging to the opposite portion of the camway by becoming engaged with the adjacent contiguous hook-point or concavitySO of theinteriorcam. (See Fig. 4:.) This breaks the force otvthe retractive movenient of the plunger-sta. On the continuedl movement of the sweep the wrist is carried over by the force of the spring, so as to con-.

tact with the side wall 26 diagonally opposite to the hook-point 30, and the spring 11, therefore, having a free play, will retract the plunger and carrythe wrist-of the swinging pitman back to the opposite end portion of the way, as shown in Fig. 5 of the drawings, thev curved walls of the way serving to-retard to some extent the retractive movement of thev changed to present an increasing resistance` to the rearward `movement of the wrist thereover. In other words, during the retraction of the wrist the, block will be moving toward a position at right angles to such retractile movement, and the shock usuallyincident to such retraction will-therefore be minimized,

and the strain will be removed from the draftanimals operating the sweep. The curvature f of the outer side-wall 26holds the sweep off the horse until the wrist-roller reaches the extreme end of the said wall, where the completion of the retractive movement takes place. It will also be observed that the plunger-remains at rest immediately after its re-- bound until the wrist-pin traverses one of the end or shorter portions of the camway, thus giving sufficient time to supply material to the press without stopping the draft-animals.

In Fig. 5 the power-head is shown in the position at the time when the plunger is substantially at rest, though the. sweep is-being.

carried around by the horse. During this period the feeder can supply the press-box` with a fresh amount of hay.

The constructiondescribed permits of acontinuous operation of baling with a mini-lv mum expenditure of power, besides insuring a positive and reliable action of the plunger with a minimum strain upon the draft animal or animals attached to the sweep.

It is thought that the construction,'operation, and many advantages of the herein-'described baling-press will be readily apparent Ato those familiar with the art without further description, and I willialso have it understood that various changes in the form, proportion, and minor details of construction may. be resorted to without departing from the principle or sacrificing any of the advantages of this invention. r

The prominent features of my hay-press are the arrangement of the straight solid plungerstaff which is guided on the pivot-post of the sweep and is operated from the power-head by a pivoted pitman connection and the p'eculiar Aconstruction of the power-head with its central interior cam-block 3l, which has two functions-first, to retard the retractive Vmovement of the plunger-stadY and prevent the shock being transmitted with great force to the sweep, and, second, to allow for feeding the press-box without stopping the draft-ani- IOO mals.` The simplicity of the Aconstruction which enables these results to beV accomplished is a point not to be overlooked. There is nothing complex about the construction or operation of my press which theaverage farmer-may not readily understand.

kHaving thus describedthe invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a baling-press, the combination with a press-box, a rotary power-head in rear of said box, a stationary pivot-post for saidv head, and a plunger within the press-box, of` a plunger-statt having rigid connection with the plunger and provided with a longitudinal slot for the reception ot' the pivot-post of the power-head, whereby said pivot-post constitutes guiding means for the plunger-staff to prevent lateral movement of the latter, a

retracting device connectedV to the rear end of the plunger-stad, a pitman having pivotal connection at one end with the'plunger-statt at a point between the press-boxand pivotpost, the opposite end ofsaidpi-tmanhaving pivotal connection with the power-head at an eccentric point, and the axis of the power-head being llocateddirectly in rearfof the pivotal connection -xbetweenthe Vpitman and the plunger-sta, whereby afconstantly-.

increasingleverage Will-be exerted upon the IIO plunger during its forward movement to effect the application of correspondingly-increasing pressure as the resistance of the bale increases.

2. In a balin g-press, the combination with a press-box, a power-base extended rearwardly from the box, a horizontal bearing roller mounted in the base at a point intermediate of its ends, and a block mounted upon said base at the rear extremity thereof, of a plunger within the boX, a plunger-staff rigidly fixed thereto and provided adjacent to its rear end with a longitudinal slot, a pivot-post upstanding from the power-base, au antifriction-roller mounted on said post and disposed within the slot of the plunger-stati, a rotary power head mounted on said pivot post, whereby said post performs the triple function of guiding means for the staff, an axle for the antifriction-roller and a support for the power-head, a pitman eccentrically connected to the power-head and pivoted at its outer end to the plunger-staff at a point between the pivot-post and press-box, and plunger-retracting mechanism carried jointly by the rear end of the plunger and the block mounted on the base.

3. In a baling-press, the combination with the plunger and the plunger connection having a wrist, of airotary power-head provided with asubstantially oblong camway, the outer side walls of which are provided with thrustnotches located at diagonally opposite corners of the Way, a block defining one Wall of the way andterminatingopposite the notches,

, and means for retracting the plunger to cause the wrist when released from a notch to travel upon the block from one end to the other thereof for presentation to a succeeding notch, whereby the change in position of the block, due to the continued rotation of the head during the retraction of the plunger, will present an increasing resistance to such retraction and thereby minimize the shock incident thereto.

4:. In a baling-press, the combination with a plunger and a pitman having a wrist, of a rotary power-head provided with a substantially oblong opening and with diagonally-opposed thrust-notches formed in the side walls of the opening, a sigmoidal block centered within the opening and having its concave portions disposed adjacent to the notches to receive the wrist as it escapes therefrom, and means for retracting the plunger to cause the Wrist to travel from end to end of the block, Whereby said block opposes an increasing resistance to the retraction of the plunger for the purpose of minimizing the shock incident thereto.

5. In a baling-press, the combination with the plunger and the pitman having a Wrist, of a rotary power-head provided with a. substantially oblong opening having diagonallyopposed thrustnotches, a block centered within the opening and having its ends disposed opposite the thrust-notches to receive the wrist, means for retracting the plunger to cause the wrist to travel from end to end of the block, and means for limiting such retraction when the Wrist has reached the rear extremity of the block, whereby the plunger will remain at rest during such continued movement of the head as is necessary to present the next succeedingthrust-notch to the Wrist.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
