IMPROVEMENTS IN BALING PRESSES
Year: 1884

page_text: I, HERBERT JOHN ALLISON; of the firm of Allison Brothers, Patent Agents, of
52 Chancery Lane, London, in the County of Middlesex, do hereby declare the
nature of my Invention for "IMPROVEMENTS IN BALING PRESSES," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My Invention relates to a duplex baling press having mechanism for operating the
duplicated parts of the same; devices for exerting pressure on the formed bales;
feeding chambers; automatically feeding mechanism; automatically operating
gates for opening and closing communication between the feeding chambers and
their respective platen chambers; automatically operating dogs, for holding sections
of material thrust into the pressing chamber from moving back; and mechanisın
for equalizing the inovomont of the sweep lover and for preventing a rebound of
the same when the platens commence their return toward the front ends of their
respective platen chambers.
Tho objects of my improvements are to provide means for increasing or
diminishing the friction of moving in the platen chamber and for automatically
feeding the material to be baled into the respective platen chambors of the press,
in the form of sections which will be gradually compressed in their passage from
the feeding chamber to the platen chamber and be closed therein by the automatic
action of mechanism so that the operator will be only required to introduce the
material alternately within the flaring and conveniently spreading open ends of the
feed chambers, and also, to provide means by which the introduced sections of
the material as they are thrust into the pressing chamber will be held in place from
moving backward, and also, to provide mechanism by which a rebound of the sweep
lever will be prevented at the time of the end of forward thrust of the platen so
that all liability of accident to the animal will be obviated and the power of
the driving mechanism of the press will be equalized.
1 accomplish these objects by means of the mechanism illustrated in the
accompanying Drawings, in which there are thirteen Figures illustrating my
Invention, in all of which the same designation of parts by letter reference,
are used.

In the Drawings A. A represents the frame of the body of the press, which press
is duplex in its character in respect to the respective chambers platens and
mechanisin for operating the adjunctive moving parts of the same by a single
system of driving gear mechanism. These duplex parts may be arranged
horizontally and neighboring side by side, though I prefer to arrange them
vertically neighboring and one over the other, as shown.
These duplicated parts in my improved press are the platen chambers B and B',
feed openings aand a¹ connecting each to its respective platen chamber from the
same and one side of the press, pressing chambers & and b₁ commencing at the rear
end throw of the platens and extending rearward to the forward end of the baling
chamber, the baling chambers C, C, extending rearward from the pressing
chambers to the rear end of the body of the press, the feeding chambers D, DT,
connecting respectively with the platen chambers B, B¹, through their respectivo
feed openings a, a, feeding mechanism E, E', moving in direction from the outer
end openings c, c¹, feed chamber clearing gates F, and F, quadrant pinions G
and G; racks H, H', for operating said gates; platens I and I¹, pitmans J and J¹;
crank arms K and K' for operating the platens from the gear operating mechanism
of the press friction lining L, L, of baling chambers C, C, depressing bars d, d¹,
and their draw bolts e, e', and brackets f, f, for adjusting said friction linings in
relation to the permanent opposite side lining of said baling chambers.
As a description of one of each of the above named duplicate parts will suffice
for that of the other parts I will describo only those parts and eleinents shown in
the upper half or horizontal portions of the press in the Drawings.
The frame work of the press is made to include the operating gear mechanism,
the platen chambers, press chambers and baling chambers. This frame is so made
as to enclose between its side portions a horizontal middle partition A' formed by
cross bars framed with the middlo horizontal plates of the frame and bottom
lining g of the upper series of chambers and top linings g' of the lower series of
similar chambers. This partition completely separates tho two series of chambers.
In one of the side linings or walls of the platen chamber B, is made feed openings a
which have a vertical extension equal to the vertical distance of the upper and
lower linings of said chambers aro apart, and with a horizontal extension a few
inches shorter than the length of the movement of the platen I in said chamber.
Pressing chamber b is made with closed sides, top and bottom linings or walls in
which each one of each two of its oppositely located walls is parallel with the
other.
The lower wall or floor lining g of baling chamber C is arranged on the
same horizontal plane with the floors of the platen and pressing chambers and is
fixed in position, and tho two oppositely located sides of each of these baling
chambers are made open from the horizontal plane of their respective friction
linings L, L', to the horizontal plane of the bearing surfaces of linings g and g
respectively as shown in Figures 2, 3, 4 and 8. These openings M extend in s
horizontal direction from the rear end of pressing chambers b, b, to the rear end
of the press and said linings L, L', and g, g¹, of these baling chambers are free from
projecting marginal bounding ledges or guiding strips.

page_text: Secured to linings L, L', and g, g', at about central in the width of their bearing
surfaces, are longitudinal ways m, m. These ways are preferably made of metal,
and with a V shaped form in their cross arm though they may be made half round
or oval or rectangular in form of cross direction and if preferred they may be made
of hard wood. These ways in each baling chamber are in situation opposite each
other one above and one below as shown in Figures 4 and 8 and they extend from
the rear end of the baling chainber to near the forward end of pressing chamber b, b¹,
as shown in Figure 3. M' is the partition board made in the usual manner and
provided with tying off slots as heretobefore made.
The opposite ends or edges (above or below) are each provided with groove m
corresponding in form, size and situation with the forin, size and situation of
ways m secured to the linings of the baling chamber, so that said groove will
engage with said ways and be held therewith and guided in its progressively
rearward movement toward the discharge ends of the baling chambers. Each face
side of said partition boards is provided with two or more spurs, which project to
a short distance outward from the plane of the face surface of the board. The
spurs engage in the end of the bale, the board is set against and held with the
bale as it and the board is being progressively moved rearward, so that the bale is
steadied and held from twisting, at the same time the ways m, m, will themselves
be made to hold with longitudinal grooves which will be gradually formed in the
sides of the bale by said ways as the material is being forced into the pressing
chamber. By thus making the two oppositely located sides M of the baling
chamber to consist of a single opening extending from lining to lining the bale may
bo tied off nearer its longitudinal corners, and any number of tics may be applied
to the bale in a convenient manner, the partition board being provided with tying
off slots to correspond.
The upper wall of lining L of baling chamber C is made of planking boards
which are continuous with the upper lining or walls of the platen and press
chambers; these planking boards are held to the upper cross timbers A³ of the
frame by bolts or screws as shown in Figures 1 and 3.
The portion of these planking boards which extends rearward of pressing
chamber band forms the upper side lining of the baling chambers, is free to be
deflected in a vertical direction from a true plane line.
Placed loosely on the upper side of friction lining board L of bale chamber C
and between the upper longitudinal plates of the frame is the stiffening rack N
formed of bars n and tie pieces n¹ which are held together by bolts. This rack is
made with a length sufficient to be extended from the rear end of the lining of
pressing chamber b to the rear end of the baling chamber. This stiffening rack,
resting on the top friction lining L of the baling chamber, rises up even with the
top surface of the longitudinal top plates of the frame and extends from side to
side between said top plates as shown. Secured to the rear end of this stiffening
rack is cross bar n²; arranged across the rear end portions of this stiffening rack N
is depressing bar d, which is made with notches in its end portions as at n³ from
its lower sides so as to readily receive the lower side portions of the bar between
the shoulders of these notches between the top plates as shown in Figure 4.
The outer projecting ends of this depressing bar are pierced, and receive screw
threaded draw bolts e, e, which bolts are each provided at one end with a head,
and the other end with a screw nut e, e. These draw bolts also pass through
brackets ff, secured to the sides of the frame on a vertical line with the holes
made in the depressing bar d and force the rear end of stiffening rack N and the
top lining L downward so that it will be deflected from a true parallel line with
the floor or bottom lining g and cause the vertical extension of the rear end of
baling chamber C to be a little less than the vertical extension forward end of the
same chamber.
A slacking of the nuts will relieve this depressing bar and permit the top lining
of the chamber to resume its normal position. The lower series of chambers B', 6,

page_text: and C are made substantially in the same manner, with this difference; the
bottom lining L' of lower baling chamber C¹ is made to be a friction lining and
capable of being deflected, the same as friction lining L of the upper baling
chamber and the stiffening rack n' made similar to and operating, as shown.
Secured to a side of the body of the press, and extending outward from the same
froin feed opening a of upper platen chamber B, in feeding chamber D which feed
chamber has its two oppositely located sides b³, b³, made to flare outwardly, as
they are extended outward from said feed opening.
The contracted end of the feed chamber terminates at said feed opening, and is
the discharge end, while the enlarged end is open and is the recoiving mouth of the
chamber. I prefer to make the transversely located sides 64, 6, of this fced
chamber, also flaring in part or whole, as such flaro will increase the capacity of
the receiving mouth.
The inner end of wall 6' of feeding chamber D is made to curve back in
direction of the backward movement of the platen I, and towards the margin edge
of the feed opening a as at x shown in Figures 1 and 6. By the above described
form of foeding chamber the walls of the same are made to compact the material to
be baled while it is being thrust forward from the receiving mouth through this
chamber, and be discharged into the platen chamber and each charge of hay (or
other material) will be introduced into said platon chamber, in the form of a
partially compressed charge which will form one of several sections of a bale, when
the same is completed and which will be readily detached from the other similarly
formed sections of the bale when it is broken open.
Arranged at the sides of the oppositely located flaring sides 62, 63, of feeding
chambor Dare enclosed feed mechanism chambers O, O', which enclose each foed
mechanism. These chambers O, O¹, communicate with the feeding chamber
through openings or slots p, p, made in the respective side walls b², b³, as shown in
Figures 2, 6, 7 and 8, and through slots or openings p, p, project the moving
spurs q, q, of feed mechanism E, E¹, which engages with tho charges of hay (or
other material to be pressed) to carry the saine from the receiving mouth of the
feed chamber into the platen chamber, through feed opening a in the form of a
partly compressed section of a bale.
The preferred form of feeding mechanism is shown by full lines in Figures 2, 6,
7, and 8, and dotted lines in Figure 1 and consists of vertical shafts r, r, passing
through chambers E, E¹, at a short distance from the ends of said chambers and
having a series of sprocket wheels r¹, 1, 1, 2, secured to each so as to revolve
with the same carried by said sprocket wheels and endless chain with the links
of which (at distances of about four inches more or less apart) are made spurs q. I.
These spurs are carried by the said chain in direction indicated by arrows 1 in
Figures 1, 6, and 8, so that the spurs, projecting the feeding chainber from its
flaring walls will be carried toward feed openings a, while, when they are returned
they will move in an opposito direction in chambers O, Oi. The endless chains 7
are supported from sagging and against being crowded back by receased ways s
in which the liuks move; and the edgos of slots p, p, in which spurs q, q, move aro
preserved from wear by metal strips at all as shown in Figures 2, 6, 7 and 8. The
sprocket wheel shaft 7 in feed mechanism chamber O, nearest to platen chamber B,
is set as near to said chamber as possible to have spurs q clear the sides of the
platen neighboring the ends of the spurs as they turn back with the sprocket
wheel off from feed chamber a. Tho portion of flaring wall 62 of the feed
chamber is made with such a curve that the recessed ways 8, 8, and slots p, p, will
be made to gradually extend beyond spurs q, q, as the latter turns back at curve x.
Secured to the lower ends of vertical sprocket wheel shafts r, r, nearest to the
body of the press, are gear wheels Q, Q', made each with an equal diameter as tho
other and working each with the other to revolve said shaft in opposite directions
and carry the series of spurs in direction of arrow 1 as iudicated in Figures 2
and 6. Secured to one of the same shafts r so as to revolve with the same is a

page_text: sprocket wheel R which sprocket wheel is actuated by sprocket wheel R' and
endless chain R2 and this second sprocket wheel R' is actuated by endless chain R
and sprocket wheel R' secured to the vertical driving shaft S.
Supported in vertical bearings in longitudinal plates A, A, of the frame and at
near the rear edge of feed opening a is vertical shaft T to which is rigidly secured
gate F. Secured to the upper end of gate shaft T is quadrant pinion G which is
made with a tripping projection t and catching notch t
This quadrant pinion is so set in relation to gate F that when the former is folded
back into flaring side wall 63 of feed chamber D the first cogs of the series in
pinion G will be made to project off over the top of the press body as shown in
Figure 1, when tripping projection t and notch t¹ will be relatively on a vertical
line with gate F. Being thus arranged in relation to gate F pinion G will, through
shaft T turn said gate from position against side 6 of the feed chamber to position
parallel with the line of movement of platen I and close feed opening a, as shown
and indicated in Figure 7. Pivoted to bracket u secured to platen I, is rack
bar H Figures 1 and 3. To the free end of said rack bar is secured rack u¹ having
cogs corresponding with cogs of quadrant pinion G with which said rack is to
engage. Immediately rearward of the series of cogs in u¹ is check us against
which projection t will strike whon pinion G is turned up by the pushing force of
rack bar H, when the latter is thrust forward.
Pivoted to the upper side of the press or to an adjunct thereto is dog us having
spring u bearing against its back for throwing it forward to engage with notch
in pinion G when the latter has been turned up to its full distance by the movement
of rack bar H. Pivoted to the top of the press is lever us; this lever is connected
at its lower end to dog u³ at a point about at the middle of its length by connecting
rod u Secured to rack bar H at a point back of the rearward cog of the series
in rack ua little less than the length of the forward movement of the platen is
trip block u, which is made to strike against the upper ond of lever us and thrust
it forward (just before the platen has finished its forward thrust) and through
connecting rod u draw dog u³ out from engagement, with pinion G so as to leave
the latter free to be turned back.
Secured to the upper end of quadrant pinion shaft. T is eccentrical quadrant
pulley T Figures 1 and 11. This pulley is so arranged in relation to quadrant
pinion G as to be in opposition to the same and is connected (at its point of greatest
throw) to compression spiral spring T2 by pull strap, chain or cord . This
spring T2 is enclosed in holder T" which is secured to the top of the press; the
spiral spring is mado to have its forward end bear against the forward ond of
holder T's and a drawing rod t³ passing through the forward end of the holder and
also through the spring, draws on the rear end of the latter and compresses the
same when a drawing strain is exerted on draw strap or cord by eccentric
quadrant pulley T¹; by the employment of this latter device, with the compression
spiral spring T, the elastic pressure is made to exert equal force on pulley T for
turning shaft T and swinging gate F from closing position at feed opening a to an
open position at the side of the feeding chamber as illustrated in Figure 1.
Made in the top of the press is a narrow slot g³ in which bracket u (attached to
platen I and connected with rack bar H) works as shown in Figures 1 and 3.
In my duplex press I duplicate all the above described parts except the sprocket
wheel shafts r, r, of feeding mechanism E, E, for said shafts extend from top to
bottom of the press and pass through their respective feed mechanism chambers of
both feeding chambers to actuate simulaneously the feeding mechanism.
The shaft T of lower clearing gate F1 is made separate and independent of shaft
of upper gate F and all adjunctive parts of the lower gate F and its shaft T and
rack bar H and its adjuncts, and dogs u³ and its adjuncts and compression spiral
spring T and its adjuncts are similar to the parts above described and are applied
from the lower side of the press for operating lower gate F' in the same manner as
is upper gate F but alternately with the same according as platens I, II, are

page_text: respectively moved alternately in opposite directions in their respective chambers
and forward and back past their respective feed openings a, a'.
The duplicated platens I, I', are so geared to the driving gear mechanism that
they are made to move in their respective platen chambers B; B₁, in a reciprocating
manner with platen I moving forward, while platen I is being drawn back.
To each of these platens is pivoted pitmans J, J', the opposite ends of these
pitmans are cach connected with crank arm K carried by vertical shaft U³
supported in proper bearings by the frame work of the press. Secured to double
crank shaft U between the cranks is gear wheel Us, which gear wheel is actuated
by pinion U attached to vertical shaft S which shaft is supported in proper
bearings from a side of the framework of the press. The upper end of shaft S is
preferably squared, and attached to it is sweep lever V, by a squared socket mado
with the connecting end of said lever and the sweep is steadied by a ring collar and
braces or equivalent devices. Mounted on shaft S at a point below the sweep, and
at about on a plane with the top of the press body is bevel gear v supported in
proper bearings from the timbers of the press. Mounted on this horizontal shaft is
fly wheel W which will be revolved at high speed when bevel gear von shaft S
is revolved by sweep lever V and the momentum of said fly wheel will operate
to aid the animal drawing on the sweep lever to carry pitmans J, J¹, past the
centre of the crank arms at the finish of each stroke of the platens, when the
resistance to the platens is the greatest; and also operate to provent rebound of
the sweep after the pitmans have passed the centres of said crank arm.
The movement of sweep lever V in direction of arrows in Figure 1 will revolve
drum shaft S and give motion to sprocket wheel R on the said shaft at the same
time motion is imparted to double crank shaft U² and fly wheel W.
Working in slots made on the top and bottom linings of the press are pivoted a
series of dogs Y, the engaging ends y of these dogs are made with a vertical linc
of surface in front and with an inclined line of surface running rearwardly as
shown. The dogs working through the upper or top linings of both the platen
chambers are weighted forward of their pivots while the dogs working through
perforations made in the lower or bottom linings of said chambers are weighted
rearward of their pivots; made with the rear end of each of said dogs is an
incline y Figure 3..
Secured to the rear end of cach platen and to the upper and lower sides thereof
are wedging blocks z, z, in number and position corresponding with the number
and: position of dogs Y. Made in the top and bottom linings of the respectivo
platen chambers are slots 2¹, z¹, corresponding in number size and place with the
number size and place of wedging blocks s, z. These slots ', z¹, are made with n
length from tho rear end of the top and bottom linings of the platen chambers
forward to a distance equal to the length of the movement of the platens in said
chambers.
When the platens are moved forward, the wedging blocks z, z, will move forward
in slots 21, ', until the platens have made their full movement and will carry
wedging blocks 2, 2, against inclines y¹ of the dogs and force their engaging ends y
inward toward said platens and into recesses 22, 23, provided in the upper and lower
sides of said platens from their forward ends.
A belt wheel Z may be secured to the fly wheel shaft for driving the genr
mechanism of the press from any convenient power for operating the soveral
moving parts of the press. In such a case I would employ a clutch with the fly
wheel and belt wheel for the ready and convenient removal of the power from or
application of the same to the gear mechanism of the press.
The manner in which the several parts of my improved press operate is as
follows:
The top lining L of upper baling chamber B and bottom lining L' of lower
chamber B will be deflected as indicated by dotted lines in Figure 3 so as to give
such a sufficient contraction to the discharge ends of said chamber as will produce

page_text: an amount of friction which will be required to produce bales of preferred density.
This deflection of said linings is produced by turning screw nuts c, e², Figures 1, 2
and 3 and 4 on draw bolts e, e¹, against d, d, when said base will be drawn against
the rear ends of stiffening racks N, N¹, bearing against linings ↳ and L' and through
said racks deflect said lining from true horizontal lines as shown by full lines in
Figure 3, to slightly inclined lines as indicated by dotted lines in the same Figure.
The forward ends of said racks will be held from raising by their being held
beneath cross bars A² as shown in Figures 1 and 3. By these above described
means, one of the lining walls of each baling chamber, will be adapted to be set at
will at a gradually inclined line (in relation to the oppositely located horizontal
lining) which will extend from the rear end of pressing chambers b¹, b', to the
discharge ends of said baling chambers without any disturbances of the frame of
the press as heretofore required for producing a frictional resistance to the passage
of the bale from the baling chamber. If preferred in some cases the stiffening
racks N, N¹, may be omitted and bars d, d, may be made to have bearing directly
on linings L, L. In such a case the deflecting lines of linings L, LA, will naturally
partake a slightly curved form.
Platens I, I, are operated in a reciprocating manner in their respective chambers,
with the movements of the upper platen alternately in opposite directions with
those of the lower platen when the material to be formed into bales is introduced
into the platen chambers through their respective feed openings a, a, the respective
platens will by their alternate forward movements thrust forward alternately, tho
charges of material from their respective chambers B, B¹, into their contiguous
pressing chambers b, b¹, where they will be shaped in a compacted soction
to be subsequently alternately thrust rearward into their respective baling
chambers C, C¹.
When the charges of material in the platen chambers are being thrust rearward,
in direction of arrow 3 in Figure 3, the material thus moved will be made to slido
against the inclines made with the engaging ends y of dog Y and force said
engaging ends outward from said material and elevate the opposite ends of said
dogs and when the platens have made their full extent thrust towards their
respective pressing chambers the material will be carried fully into the latter and
slightly past the engaging ends of said dogs, and at the same time the wedging
blocks,, (secured to the rear end portion of the respective platens) will ride on
the inclined surface y¹ of dogs Y, and force the engaging ends of the same inward,
so that they will bear against the rear side edge of the section of the compacted
material thus thrust into the pressing chambers and be held from passing or moving
back into the platen chamber. These dogs are positively operated in one direction
by the moving compacted section of material being pressed and in the opposite
direction by the platen, and the use of springs is dispensed with for holding them
in effective engagement with the compacted material.
Platens I, I, are operated alternately forward and backward in their respective
platen chambers B, B₁, by the pitmans J, J¹, as they are actuated by crank arms K
revolved by shaft U through the medium of gear U³ and pinion U shaft S and
sweep lever V or belt wheel Z.
When the gear mechanism moving the platens is to be operated by a belt wheel
the power will be transferred from said belt wheel to the platens through horizontal
shaft pinion 1 bevel gear v shaft S, pinion U, gear U³, double crank shaft U³
crank arm K and pitman J, when fly wheel W will operate to equalize the movement
of these several parts.
When the gear mechanism is to be operated by the sweep lever V pinion U* on
shaft S and gear U³ on the double crank shaft will be dispensed with and a large
driving gear 1 (shown in dotted lines in Figures 1) will be secured to shaft S
in place of pinion U and a small gear wheel x (about one half the diameter of
gear ) will be secured to double crank shaft Us in plan of gear U so that the
double crank shaft will be made to revolve twice to each revolution of driving
shaft S. When swoop lever V is made to revolve shaft S, bevel geár v on said

page_text: shaft will actuate bevel pinion v³ and through it revolve fly wheel W to a high
speed and thereby equalize the speed of driving shaft S, when crank arm K on
passing the centres and also prevent a sudden acceleration of the movement of the
sweep lever toward the animal drawing on the same at the time of finish of the
forward thrusts of the platens and its start backward and thereby remove all
possibility of endangering the animal by a rebound of the sweep as heretofore had
in baling presses driven by sweep.lever.
When the pressing gear mechanism and platens are being operated as above
described, sprocket gear R attached to driving shaft S, will through endless
chains R³ revolve sprocket wheel R which sprocket wheel will through endless
chain R³ and sprocket wheel R revolve one of the shafts r and gear Q in direction
of arrow 4 in Figures 1 and 2, gear Q will revolve Q', and its attached shaft r in
direction of arrows 4 in same Figure.
The shafts r, r, will revolve their respective sprocket wheels r¹, r³, carrying
chains moving in recessed ways 8, 8, with their attached spurs q, q, moving in
slots p, p, in direction of arrows 1 in Figures 1 and 6, when the operator
introduces a fork full of hay (or other material to be pressed) into the feeding
chamber D (or D') the rapidly moving series of spurs q, q, of feeding mechanism E
(or E¹) will engage with said material and carry it inward toward feed opening a
(or a') while the material is being carried inward; the inclined or contracting
sides of feed chambers D (or D¹) will operate to gradually compress the material
as it is being advanced into the platen chamber B (or B¹) as the material is being
compressed by the inclined sides of said chamber feeding spurs 9, 9, will be
made to have their strength of engagement with the material gradually increased
because of the increased compactness of the latter, when approaching the feed
openings a (or a¹) before entering the platen chamber.
It will be observed that the feed mechanism working in the inclined side b* of
the feed chambers, next to the head end of the platen chamber is made to run
nearer to the platen chamber, and that this incline curves back at x so that spurs q
will have engagement with the compacted charges of materia being introduced :
until it has nearly all been introduced into the platen chamber, and that this
curved portion of wall b² reverses the entire length of spurs q in recessed slots s
and operates to withdraw said spurs from the material just about at the point the
curved portion x of said wall contributes to enlarge the throat of the feed chamber
at the feed opening to the platen chamber. By this form of construction and 3
arrangement of said parts the side portions of the completed material next to the
face of the platen (before it is carried forward) is made to fully enter the platen
chamber before the former has been moved forward past curved portion of wall b
when the compacted charge has been introduced into the platen chamber the platen
moving forward will force the charge towards and into pressing chamber b (or b¹)
when dogs Y will be operated by wedging blocks 2, 3, and made to hold against
the rear side of said compressed section of material.
When the charge of hay compacted in the feeding chamber D (or D¹) has been
about fully introduced within the platen chamber by feed mechanism E (or E¹)
platen I (or I¹) will have commenced its forward movement towards pressing
chamber b (or b') and continuing its forward movement it will carry pivoted rack
bar H (or H¹) forward with its rack ul engage with quadrant pinion G (or G¹) and
operating the same to swing gate F (or F¹) inward from its folding position at
inclined side 6 of feeding chamber, as shown in Figure 6 to a closed position at
feed opening a (or a¹) at the side of the platen as indicated by dotted lines in same t
Figure. The gate in swinging forward to close feed opening a (or a¹) will carry
before it into the platen chamber whatever of the rear end portion of the
compressed charge of material there may be in the food chamber at the time the
gate is closed. This closed gate will operate temporarily, the same as the opposite
side wall of the platen chamber for guiding the compacted charge of material in t
its passage to pressing chambers b (or b¹).

page_text: As soon as the quadrant pinion G (or G¹) has been operated by rack bar H (or
F) to fully close gate F (or F) tripping projection t will arrive at check u² on
said rack bar and lift the same. At the same time dog u³ is made to engage with
notch in said pinion and hold the same locked from turning back. This dog ³
and quadrant pinion G (or G¹) is made to lock the gate in a closed position against
the side of the platen chamber until the platen has been moved to within three
or four inches of the completion of its forward thrust when the platen has nearly
completed its forward movement towards pressing chambers 6 (or b¹) tripping
block carried on the rear portion of rack bar H (or H') will strike the upper
end of lever us and force the same forward towards quadrant pinion G (or G')
when dog u³ will be drawn back out of engagement with notch t'in said pinion
and the pinion and its connected gate will be free to be turned back to their
normal positions by the united action of quadrant pulley T, and spiral spring T
and their connecting strap or chain and be held by the same with gate F
(or F) folded in its place in the face side of incline b³ of the feed chamber.
When gate F (or F) is folded back to its normal position in its side of the feed
chamber a second charge of material will be introduced in the feed chamber where
the several devices will operate again to effect a like compression of the charge,
and also the introduction of the same in a compacted form into the platen
chambers; and also to shutting in of the charge by the gate and a thrusting
forward of the same against the preceding charge and moving both forward in the
pressing chamber and towards baling chamber C (or C³).
As before stated the upper and lower feeding mechanism E, E¹, of the respective
feeding chambers are moved simultaneously while gates F, F', are operated
alternately with the movements of each of the latter, timed with the movement of
the respective platens which primarily operate to close and release their holding as
above described.
It will therefore be readily understood that the charges of material to be formed
into bales are to be introduced alternately in feeding chambers D, D¹, at the times
their respective gates F, F, are turned open like as shown in feed chamber D in
Figure 2 and such introduction of charges will be stopped while the gates are
closed like as shown in lower feed chamber D¹ in same Figure.
By these above described improvements I am enabled to form two bales
simultaneously by alternato feed charges introduced mechanically into the platen
chambers in a compacted form of sections.
In Figure 9 the gate F (or F¹) is shown to be made with a hollow sleeve cª
having arms c³, c³, separated by slots c with slots c, c, terminating with
recesses made with sleeve portion of the gate; when this gate is turned back
into its place inside are feeding chamber D (or D') spurs q, q, of the feeding
mechanism will be readily received into slots c, c, between arms c³, c³, while spurs
when turning at the sleeve of the gate will move recesses c³, c³, whether the gate
be stationary or swinging towards or from sides bª.
If preferred tripping projection t made on pinion G secured to gate shaft T and
catching notch t¹ made in said pinion may be made with separate and independent
piece from pinion G and be secured to the same shaft, and also if preferred a
weight cord and pulley may be substituted for spring T2 for operating with the
quadrant pulley T₁ for swinging gate F from a closed position to an open one and
further band pulleys and bands or band wheels may be employed in lieu of
sprocket wheels and endless chains for communicating motion to the foed
mechanism from the revolving mechanism operating the pitmans of the platens.
By my above described improvements a greater quantity of material will be
formed into bales in a given time than has heretofore been accomplished, because
of the automatical feeding of the material to the platen chambers in a partly
pressed or compacted form, from inaterial alternately introduced into the flaring
ends of the feed chambers in a convenient manner without any expenditure of
time or manual labor for its introduction through the feeding chambers to the
platen chambers.

page_text: I am aware that shallow and flaring sided hoppers have been employed with the
feed opening to platen chambers of a baling press; for the purpose of conducting
in a more cleanly manner the material to be baled into the platen chamber. Such
hoppers form no part of my Invention as they are not in the least adapted to
compact the material in its passage to the platen chamber as does my feeding
chambers and further these shallow hoppers are not in the least adapted to receive
a feeding mechanism in their sides for coaction with the sides for forming and
introducing compacted sections of material into the platen chamber as in my above
described feeding chamber.
When bales have been formed of compacted material by successive charges
received from the feeding chambers the bales will be tied off or banded and ejected
in the usual manner practiced by the trade which is so well known as to require
no particular description.
