Application tiled October 1, 1903. 'Seria1No. 175,295. (No model.)

'o @ZZ whom t muy concern:

Be it known that I, RALIEGH P. WHITE, of

Kansas City, county of Jackson, and State of signed more particularly for baling hay,straw, andlike material, and'- embodying usually a balingechamber, a hopper communicating therewith, and a plunger adapted to be operated by suitable means baling-chamber on the material entering from the hopper.

and acting within the successive charges of In connection with machines of this character it is a common practice to provide mechanism for feeding' the material into the baling-chamber, which mechanism acts'to press the charge in the hopper well downward into the chamber, so that the full and proper amount will be carried with certainty forward by the advance `of the plunger and compressed with the previous charges.

It is to feeding mechanisms of this nature that my invention is principally directed; and it consists of feeding mechanism invention embodied therein.

plan view of the same.

Fig. 2 is a top Fig. 3 is a perspective view, on an enlarged scale, showing the n n baling end and power end of the press with the feedmg mechanism 1n an inact1ve position.

Fig. 4 is a vertical longitudinal sectional elevation through the baling-chamber, showing the feeding-arms in a raised inactive position. Fig. 5 is a the feeding-arms lowered and in action.

similar view showing Fig.

6 is a side elevation of the baling-chamber as viewed from the side that shown in Fig. 1,

of the press opposite Fig. 7 is a side elevation showing how the feeding-arm is tripped or yields when it encounters an obstruction.

Referring to the drawings, 1 represents the power end of the press, and 2 the baling end, which are sustained, respectively, by axles 3 and t, provided with carrying-wheels 5 and 6, by which the press may be transported from place to place. i

The power end of the press comprises a suitable frame or casting 7, in which the power mechanism presently to be described is mounted and by which it is given support, while the baling end of the press consists of a horizontal longitudinally-extending balingchamber 8, open at its top at its front end for the introduction ofthe charges, at which point it is provided with a hopper 9, into which the material to be compressed is fed preparatory to entering the baling-chamber. The balingchamber and the frame 7 are rigidly and firmly connected together by a longitudinal bar or beam lO.

12 represents a reciprocating plunger connected to the rear end of a pitman l1, which plunger is adapted when the pitmanis reciprocated to enter the front end of the balingchamber and to act on the charges of material introduced through the top opening from the hopper. At its opposite end the pitman is acted on by a rotary trip-lever 13, mounted on a vertical shaft 1li, which is mounted in bearings in the frame 7 and which is operated in the usual manner by asweep 15, connected with the upper end of the shaft.

"he trip-lever is provided with frictionrollers 16 and 17, which as it revolves successively engage the end of the pitman, and maintaining engagement therewith through the medium of connecting-links 1S and 19 they force the pitman forward until it arrives at a predetermined point, where the active roller disengages it, and the pitman being released it quickly rebounds under the resistance offered by the compressed mass and returns to its former position ready to be engaged and carried again forward by the other roller.

The foregoing parts may be and are of the usual and customary construction, and eX- the charges will be properly fed in front of the plunger, and the arms are designed to act cept in so far as hereinafter indicated they form no part of the present invention.

In applying my present invention I mount in bearings 20 and 21 on the forward end of the baling-chamber and above the path of the plunger a horizontal rock-shaft 2 2, which has fixed to one end a segment-sheave 23, to which is connected a chain 24, extending downward and around a guide-pulley 25 on the outside of the baling-chamber and finally forward to the power end of the press, where it is operatively connected with the sweep in such manner, as will be more fully described hereinafter, that it will be drawn forward intermittently by the action of the trip-lever as the latter is revolved by the sweep, thereby in-v termittently rocking the shaft 22. At its opf posit-e end the shaft 22 has fixed to it, as

shown in Fig. 6, a second segment-sheave 26, to which is connected one end of a chain 27, whose opposite end is connected with the forward end of a spiral spring 28, having its rear end adjustably connected with a bracket 29 on the side of the baling-chamber, the adjustable connection comprising a link 3() on the spring, provided with a number of holes 31, either adapted to be passed over a pin 32 on the bracket. The relative connection of the chains 24 and 27 with their respective sheaves is such thatv when the chain 24 is drawn forward and its sheave drawn downward the other sheave will also by reason of its connection with the shaft be drawn downward and will wind up its chain, which will place the spring under tension, so that when.V

the strain on chain 24 is released the spring will draw the segment-sheave 26 upward to its former position. It will be seen, therefore, from the construction described that the intermittent pull on chain 24 will result in a corresponding rocking of the shaft 22.

Carried by shaft 22 are two feeding-arms A, which when the shaft is rocked downward, as described, will descend into and through the hopper and into the baling-chamber, the

front of the hopper being slotted vertically,`

as at 33, to admit the arms. The function of these arms is to force the material introduced Avbythe attendant into the hopper down through` the opening into the baling-chamber, so that alternately with the advance of the plunger-1 that is to say, the arms descend to perform their functions after the plunger has rebounded, and they ascend and leave the chamber when the plunger advances to compress the charge.

' In'order to eifect this relative action of the 6 parts," I prefer 4to adopt the mechanism shown feeding-arms by the trip-lever.

particularly in Figs. 1 and 2 Yfor operating the Here it will be seen that the forward end of-chain 24 is connected with a horizontal segment-sheave shaft Z1, mounted in a bearing in a horizontal the teeth on a second segment-gear D, mounted on the upper end of avertical stud CZ, projecting upward from the base of the frame 7 at a point to one side of that where the pitman is disengaged from the trip-lever. The segment D is provided with a forwardly-extending nose d', which projects'in the path of the rollers of the trip-lever, the result being that when the active roller is disengaged from the pitman and the latter has rebounded the said roller will engage this nose and will turn the segment on its axis, thereby turning the intermeshing segment C and the segment-sheave B in the opposite direction, which action will wind chain 24 and cause the feeding-arms to descend into the hopper. rIhe continued movement of the trip-lever will cause its roller to be disengaged fiom the nose CZ, and the segment being released the spring 28, acting on the feeding-arm shaft, will, through the con- 9 nection of this'shaft with the chain 24, draw the same quickly rearward, which action will turn the sheave B inward and restore the parts to their former positions, with the nose Z in position to be engaged by the following roller. It is seen, therefore, that as the sweep is revolved and the trip-leverv carried around the rollers will successively advance the pitman to press the charge and as the plunger rebounds will successively cause the feedingarms to descend and force the next charge into the chamber, the action of the plunger and feeding-arms being thus alternate and .both controlled by the operation of the triplever. Y

Owing to the fact that the plunger is not i positively retracted, it frequently happens that by reason of an unusually large charge being carelessly allowed to pass under the folder or for other causes the plunger-head binds in the baling-chamber and remains beneath the opening through which the feeding arms work, the result being that unless some means are provided to prevent the feeding -arms will contact with the plunger-head and will IOO IIO

IZO

be broken or injury caused to some of the connected parts. In order to prevent this contingency, I propose to so construct the feeding-arms that they will yield when subjected to undue resistance-such, for instance,

as an obstruction of this nature-so that the actuating mechanism will be permitted to operate without interruption and without injury to the feeding mechanism. In carrying out this idea I preferto adopt the construction'shown in Figs. 3 to 7, where it will beV seen that 'the feeding-arms are each formed of two membersvan inner one, a2, fixed to the rock-shaft 22 and comprising two arms a and a2, curved rearward at their upper ends, and an outer member a3, pivoted at its inner end between the two arms on a horizontal transverse axis a4. Fixed to the outer member just above the upper ends of the arms a and a2 is a bracket c5, provided with a'forward projection a, and to the under side of this bracket adjacent to the arm is `pivoted on a horizontal axis t7 one end of a trip-block a8, whose opposite end is jointed on an axis a between the forward ends of twolinks am, extending on opposite sides of the upper member of the feeding-arm and jointed at their rear ends' on an axis a to the upper ends of the'arms a and a2. Asa result of this construction the outer'member of the feedingarm is movable relatively to the inner member on the axis which movement is .controlled and limited by the connecting-links am and trip-block as, so that although an obstruction may be offered to the outer ends of -the feeding-arms and theirmotion may for the Vtime being be arrested the lower members of these arms will be permitted to continue to move under the action of the transmitting power and the trip-lever will be allowed to continue its movement without interruption or injury to any of the driven parts. In order, however, that the members of the feeding-arms will be maintained in operative relations and held to their work under normal conditions, I provide a spiral spring 012, which encircles a rod als, extending loosely through an opening in the extension a6 of the bracket and having its lower end loosely mounted on an axis am, connected with the trip-block between its ends, the upper end of the spring bearing against an adjustable head al, threaded on the rod, and its lower end bearing on the upper side of the'extension of the bracket and tending to hold the parts yieldingly in the position shown in Figs. 3 and .6, with the trip-block held up against the under side of the bracket extension and the outer member of the arm forming a continuation' of the inner member. It is in this position of the parts that the feeding-arms normally act, the` tension of the springs being such' as to sustain the arms against a pressure sufficient to compress the material under treatment, but not sufcient to'prevent the relative movements of the members of the arms in case undue resistance is offered, such as would result if the plunger-head remained in the baling-chamber in the path of the arms. In such a case the lower members of the arms carried by the rock-shaft would continue to move, pivoting on the axes with relation to the upper members of the` arm, drawing the trip-blocks as 'downward on their axes c7 and compressing 6 5' ,2 the sprmgs a as shown 1n Fig. 7

The 'form and relation of the connections between the two members of the arm and their connecting axes are such that when the arms are in their normal positions, as shown in Figs. 3 and 6, the parts will be locked and held yieldingly locked by the springs, so that they will stand a considerable pressure without being tripped, and therelation of these connecting parts and the operating means is such that the lower members of the arms will be permitted to move'with relation to the upper members in case an obstruction is encountered suiiicient to allow the trip-lever to continue its operation and its rollers to successively engage and disengage the operating segment-gear D, so that when an obstruction is encountered by the feeding-arms the operative mechanism will continue to act uninterruptedly without injury to the parts..

The operation of the press is as follows: As the trip-lever is revolved by the rotation of the. sweep in the usual manner the rollers will successively engage the end of the plunger-pitman and the plunger will be intermittently advanced into the baling-chamber and will act to compress the material therein, and as the rollers disengage the pitman at the end of each advancing movement the plunger will rebound and leave the chamber. The attendant in the meantime fills the hopper with hay, and after the trip-lever disengages the pitman it next engages the nose of the segmentgear D and turning said gear on its axis causes the chain.24, through the intermediate gearing, to be drawn forward, thereby rocking the shaft 22 downward and forcing the feedingarms 'into the hopper on the hay therein, which latter is caused to descend by the action of the arms into the baling-chamber in the space vacated by the plunger. As the triplever disengages the segment-gear the spring 28, acting on the end of the rock-shaft, raises the feeding-arms and returns the connected parts to their former position. As the feeding-arms leave the chamber the next roller engages the pitman and the plunger is advanced into the chamber, pushing the charge which was forced downward by the feedingarms before it, and these operations are re.- peated, the feeding-arms descending and forcing the hay into the baling-chamber as kthe IIO plunger retracts and the latter advancing as will rock on axes ai, and drawing the links am rearward the ends of the trip-blocks aswill be pulled downward on axes a7, overcoming the tension of springs a and theirtendency to-hold the trip-blocks locked against the extensions a of the brackets. This movement ofA the innerinembers of the feeding-arms with reference to the outer members will continue until the chain 24 has been pulled to its full extent forward, whereupon the trip-lever disengaging the segment-gear D the strain on the chain will be removed and the spring 28, acting on the rock-shaft, will raise the arms, whereupon springs am of the feeding-arms will act on the trip-blocks and pull them upward against the brackets, thus restoring the parts of the arms to their former operative positions. In this way there will be no interruption in the operation of the power mechanism of the press, notwithstanding the fact that the plunger may become jammed and obstruct the movements of the feedingarms.

It will be observed that the form of the feeding-arms and the relations of the two members of the same are such that the inner members are yieldable in a direction opposite the feeding movement, which feeding movement is in a downward direction, as shown in Fig. 5.
