SPECIFCATION forming part of Letters Patent No. 422,320, dated February 25, 1890.

Application filed October 12, 1889.

:To all whom, it may concern.-

Beit known that we, HENRY V. SCATTER- eooD and CHARLES F. SoAT'rEEeooD, both of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Ealing-Presses, of which the following is a full and exact description, reference being had to the accompanying drawings, which form part of this specification, and in which- Figure 1 is a side elevation of our press. Fig. 2 is a plan view, showing the toggle-joint of the plunger-'operating mechanism at the opposite side of the press from the position in which it is shown in Fig. 1. Fig. 3 is a longitudinal section of Fig. 2 at the line X X. Fig. 4 is a horizontal section, taken at the irregular line Y Y on Fig. l, but with the plunger at the extremity of its inward stroke and its operating mechanism in a corresponding position. Fig. 5 is a perspective view of one vof the division-blocks for separating thebales.

Fig. 6 'is an enlarged and detached side elevation of the upper portion of one of the shafts for our automatic locking device; and Figs. 7 and'S are enlarged and detached planvviews of the locking arms and detents for automatically stopping the outward movement of a division-block, said figures, respectively, showing a locking-arm in a protruded and an in'- truded position. f 1

Our vinvention relates to improvements on that class of baling-presses in which advantage is taken of vthe resilient power of the compressed material to effect the outward stroke of the plunger of the press, and in which the toggle-joint of the plunger-operating mechanism is not continuously connected with the sweep, to which the animal-power is attached, for the purpose of operating the press; and our invention consists of the novel construction and combination of parts herein shown and described, and particularly pointed outin our claims.

As represented in the drawings, A designates the frame-work or body of our press, said frame-Work being made in the usual form of such structures, excepting in those parts which are changed to suit the specially-de signed features of our-invention.

B is a stationary shaft-like bar, whiehis se- Serial No. 326,802. (No model.)

cured in a fixed position in the bosses of the cross-ties l by means of cross-pins 2 or other suitable fastenings. Said shaft-like bar is provided with a lcrank-like bend C, whose throw is permanently turned toward the baling-chamber of the press, and the fixed pivot 3 of said crank-like bend forms the center on which the sweep D swings to operate the plunger-operating mechanism. The body of 6o the shaft-like bar B, both above and below the crank-like bend C, forms centers for the swinging cranks E, which form portions of the toggle-levers for operating the plunger of the press. The hubs 4 of said cranks fit 65 loosely upon the body of the shaft-like bar B, so that said cranks will swing freely thereon, and the opposite end of each crank is provided with an eye 5, in which a wrist-pin 6 is secured, so as to form the centers for the outer 7o ends of the pitmen F. Said pitmen, in conjunction with the swinging cranks E, form the toggle-levers by which the plunger of the press is forced inwardly. An anti-friction roller 7 is loosely fitted to revolve on the 75 wrist-pin 6, so as to receive the thrust of the sweep of the press in a comparatively frictionless manner. The opposite end of the pitman Fis jointed by a pin 8 to the plunger G, the latter being preferably made of metal, 8o and also preferably in the form of an opensided box, whose head Q forms lthe pressingsurface of said plunger,whose lower plate is provided with rollers l0, to reduce the friction of said plunger in its reciprocations in the press, and whose upper plate is provided with a stud or hook ll, for a purpose hereinafter explained.

D is the sweep of the press or the lever to which the animal-power for operating the 9o press is applied. Said sweep is preferably made in the form of an A-frame composed of two side pieces l2, which are joined together at the outer ends, their inner ends being fitted to enter sockets or seats in a yoke I` 95 The latter contains a eentrally-located U- shaped opening, which is provided with a binder 13, so as to form a bearing or journalbox which lits the fixed pivot 43, so as to allow the sweep D to swing freely thereon. The roo face of the yoke I has a convex swell 14, that corresponds to the journal thereof on said fixed pivot and its flanks 15, which extend in a straight line directly from the opposite sides of said convex portion, said line being in effect a straight line which radiates from and passes through the center of the fixed pivot 3. Said flanks are fitted to bear successively against the anti-friction roller 7 on the wrist-pin of the swinging cranks E, so as to impart the required movements to the tog- Io gle-joints for effecting the inward strokes of the plunger.

It will be noted that the yoke I has no permanent connection with the toggle-joint, but only operates the latter while in contact there with, and it will also be noted that the pivotal centers for the swinging cranks E and for the sweep D are formed by a single piece of the form hereinbcfore described, thereby combining extreme strength with great sim? zo plicity of construction, and so that said centers are fixed at different points, on the cenr tei-line of the press, whereby the leverage of said sweep is rendered constantly variable, and will be least when said cranks are at the 2 5 extremity of their outward movement at either side, one of said positions .being shown in Fig. 2, in which the uppermost crossftie 1 is partially broken away to more clearly show the position of said cranks, and the greatest 3o leverage of said sweep will be attained when the friction-roller 7 is carried closely by the convex swell 14, so that the center lines of the swinging cranks and pitmen will range in a direct line, as shown in Fig. 4., at which 3 5 point the plunger G will be at the extremity of its inward stroke. Vhen the swinging cranks E are at the extremity of their outer movement on either side of the center line of the press, the eyes 5 of said cranks will come 4o in contact with stops 1G, formed on the crossties 1, whereby the movement of said cranksk will be terminated, and when the plunger G has nearly reached the extremity of its ontward stroke it comes in contact with a spring 17', which gradually retards its movement and prevents the eyes of the swinging cranks from striking too heavily against the stops 16.

J is a cross-head that is fitted to slide in `the guides K, which are pivoted, as at 18, to 5o the frame-work of the press, so that said guides can be swung upward, as indicated by dotted lines in Fig. 3, when occasion requires. Said cross-head is connected by springs 17 to the frame-work of the press eontiguously to the shaft so as to normally draw the cross-head in that direction. Said cross-head is fitted to engage with the stud 11 of the plunger G when the latter is near vthe termination of its inward stroke, and the 6o continued movement of said plunger will cause the springs 17 to be elongated, so that when the plunger is freed from the control of the togglc-levers, the resilience of the springs will vaid in effecting the rebounding move- 6 5 ment of said plunger toward the power end of the press.

By raising the cross-head J to the position indicated by dotted lines in Fig. 3 it will be carried out of the path of the stud 11, and the rebounding movement of the plunger G will then be effected by the resilience of the compressed material.

When preferred, the cross-head J may be dispensed with and the springs 17 may then be secured directly to the plunger and to the frame-work of the press, so that they will at all times aid in producing the rebounding movement of the plunger.

L designates spring-actuated retainers whose points enter the sides of the press and extend into the baling-chamber M, to prevent the successive charges of the material which have become compressed from following' the plunger on itsoutward strokes.

N is a folder,- which is located at the chargingend of the balingchamber M, and secured to the upper side of the frame-.work A by the spring 19. The lower face of said fold er is beveled upwardly toward the charging-opening O," and thepurpose of said folder is to fold down any loose parts of the material at the upper side of that end of a bale as each successive charge is forced intothe balingeha,mber.

P are dogs or detents which are fitted opposi tely in the vertical walls of the press, near the discharging end of the baling-chamber M, said dogs being fitted to slide laterally into said baling-chalnber for the purpose of holdingin positiomto forma stationary head against which the bales are compressed, one of the movable division-blocks Qwhich sepa- `rate the bales from each other in the operation of forming the same.l Said dogs areconneeted by links 20to arms 21, which are on the vertical shafts R, that are journaled to the outer side of the frame-work., adjacent to the discharging end of the baling-chamber. The lower end of each shaft R, is provided with an arm 22, which connects with a spring'23, whose opposite endv is. attached to a` fixed point on the frameswork A, and the effect lof said springs is to rock the shafts R, when the latter are left free to move, seas to` throw the dogs P inwardly into the position shown in Fig. 4. To the upperend of each shaft R a lever 24 is looselyiitted', so that the shaft can be turned freely in the hub of the lever, each of said levers being connected by a spring 25 to the upper side of the press, and the hub of each lever being provided with a slot 26, through which projects ay pin 27, which is secured to the shaft. Said levers nominally remainin; the position shown in Fig. 2, Where the pin 27 will be at the end of the slot 26, to effect the turning of the shaft to retract the dogs Pinto the position shown in Fig. 2, and when this retraction has been accomplished the levers will return. to their normal position.

S designates locking-arms, which are provided with slots 28, through which pivot-pins 29 pass, so that each of said arms can have both a swinglng and a sliding movement as occasion may require. A tail-piece 30, formed on the forward end of each of said lockingarms, is fitted to strike against the side of the plate to which said arm is pivoted, and

thereby the opposite end of the latter is pre-V vented from swinging out too far, and'each of said arms is provided with a spring 31, which has one end attached to the frame-work of the baling-ehainber M, and a heel 33 is also formed on each of said arms to extend outwardly. Said toe is fit-ted to enter pockets 34, formed in the opposite edges of thedivisionblocks Qwhen the latter have nearly reached a position at the discharge end of the balingchamber to serve as ahead against which a bale can bev compressed, at which point the locking-arms S will swinginwardly, their toes 32 entering the pockets of the division-blocks soas to release the vdogs P, which are forced inwardly'by the action of the springs 23, in the manner presently described, in time to debar the further outward movement of said Y divisionblock,'at which time the divisionblock and the locking mechanisms will be in the positions shown in Fig. 8. While a com-` pressed bail is still in the baling-chamber M and after said bail has been tied off, the divisioni block can be released from the hold of thedogs P, and this is effected by turning the shafts R by means of the levers 24, so as toretract said dogs into the position shown 4in Fig. 7, andas soon as this retraction occurs the resilience of theeompressed matel`rial will cause the bale to expand lengthwise to the limit of the ties around it, and by this *outer sides of the bale.

expansion the division-block will be ejected f rom the open end of the baling-chamber, and

the compressed material, by closing over the openings through which the toes k32 enter the balingphamber, will prevent said toes from entering said chamber. After the toes 32 enter the openings 34 in the division-block Q the pressure applied to the material in the press will cause said division-block to move toward the discharge end of the press until its further movement is arrested by the dogs P, and in making this lastnamed movement the plate on the innermost side of the openings 34 will be brought to bear against the convex edge of the toes 32, whereby the lock ing-arms S will be forced to swing outwardly, seas to bring the toes 32 to bear against the Then on4 turning the shafts R` to effect a retraction of the dogs P Ythe arms 21 will iirst engage with the adjacent edge of the heels 33 to push the lockingarms S endwise until the arms 2l are carried beyond the outer end of the heels 33, and

the arms 21 will bear against the outer end of said heels, so as to retain the ends of the toes 32 in contact with the sides of the bale in the baling-chatnber until the next divisionblock is carried into position to release said locking-arms and dogs in the manner hereinbefore described.

With the understanding that the sweep D swings from onevside of the press to the op-A posite side, the crank-pin ofthe crank C forming its pivotal center, and that a divisionblock is inserted through the charging-openin g O to rlie at the charging end of the balingchamber M just before the beginning of the formation of each bale, the operation of our press will be understood from the following statement: While the plunger E is at the outer extremity of its stroke, as shown in Fig. 3, the swinging cranks E being in a corresponding position at either side of the center line of the press, a charge of material is fed into the charging-opening O and the sweep D is moved in the direction required to force'the plunger G inwardly. At the beginning of said movement of the sweep the friction-roller 7 will bear against the yoke 1,

n near one of the extremities of the latter, where the sweep will exert its least leverage, the resistance of the material being then at a minimum. By the continued movement of the sweep the friction-roller 7 will be carried nearer the middle of the yoke 1, and thereby the leverage exerted by said sweep will be constantly increased until the center lines of the swinging cranks E and pitmen F range ina direct line, and at that point the leverage of the sweep will reach the maximum and the plunger G will be at the innermost extremity of its stroke. At this point there occurs a slight cessation in the movement of the plunger, while the friction-roller is in contact with the convex surface of the swell 14, and after passing this point the plunger will rebound by the resilient action of the springs 17, or of the compressed material, whereby the plunger will be returned to the outer extremity of its stroke with the toggle-joint in ofthe press. These operations are continued until a'bale of the required size has been formed. Then anotherdivision-blockis forced into the baling-chamber M, and is held'therein by the spring-retainers L until the ties are passed around the bale and fastened thereon.

Then the shaftsR are partially rotated to draw back the dogs P, so as to release the divisionblockthat has been serving as a head to compress the bale against, whereupon the endwise expansion of the compressed bale will forcibly eject said division-block from the open discharge end of the baling-chamber M. The endwise expansion of the compressed bale causes the compressed material at the sides ofthe bale to cover the openings in the sides ofthe baling-chamber, through which'the 4vtoes of the locking-arms S intrude, and there ICO IIO

a corresponding position at the opposite side by the latter are prevented from swinging inwardly to release the dogs P until a new bale, now in the process of formation, has pushed the finished bale far enough out of the dis charge end of the baling-chamber to allow a succeeding division-block Q to reach a position where its pockets 34 will be ready to rcceive the toes 32 of the locking-arms. lVhen this point is reached, the springs 23 will cause the shafts R to make a partial rotation to force said locking-arms to swing inwardly, thereby carrying the toes 32 into the pockets 34, freeing the arms 2l from the heels of the lockingarms S, thereby effecting aforcible movement of the dogs P inwardly to debar the further movement of the divisionblock Q, which then becomes a stationary head to receivek :and resist the pressure applied to the material in the bale. The finished bale,which protrudes'from the open end of the baling-chamber M, is removed therefrom by hand in time to allow the free escape of a division-block when the latter is ejected by the expansion of the next succeeding bale.

XVe are aware that Letters Patent No. 408,115 covers a construction which comprises the combination of a reciprocating plunger,a toggle-joint having one end jointed to said plunger and the other end jointed to a fixed pivot, and a sweep fulcrumed on a fixed pivot located between the pivot for the toggle-joint and the reciprocating plunger, said sweep being provided with a head having at each end a finger or horn, which extendstoward the plunger, the points of said fingers vbeing fitted to take against the knuckle of the toggle-joint before Contact is made between said knuckle and any other part of said head; but we do not claim such a construction, as it is open to many objections; but
