BARK PRESS.
This invention relates to bark presses.
The compressing machine disclosed herein has for its object the pressingof bark for the removal of fluids therefrom and for the shaping of such compressed bark into units of convenient sizes that they may be readily handled and burned in furnaces.
In bark pressing machines having foraminous cylinders it has been found that a considerable quantity of fluid remains inthe v bark adjacent the head of the piston within the cylinder and it is therefore the principal object of this-invention to provide a hollow piston adapted to receive the fluids in bark adjacent Lthe head of such piston and also sluicing means communicating with the hol.- low of the piston for removing such solid particles of the bark as may pass with the fluids to the interior of the piston.
Another defect found in bark pressing ma` chines having a cylinder open at one end and a piston reciprocable in the cylinder is in the diliiculty with which theibark pressing operations have been started.` In other words, thebark when initially starting theV oper-.ation tends to freely pass out through the open end of the cylinder without building up a resistance to the movement ofthe piston and thus drive the fluids from thev bark. It has been found also that at times during the bark pressing operations the usual mechanism provided for resisting the emission of the bark from the cylinder fails when the quantity of bark passing through the open end of the cylinder decreases to such an extent asv to eliminate that resistance which the cylinder Aitself `offers whenit is packed with bark yto capacity.
It is therefore a still furtherk object of this invention to provide in bark pressing machines a pivoted resistor jaw automatically adapted to `oppose to the passage of bark and to offer a resistance variable inversely with variations occurring in the ref sistance of the cylinder when the machine is operating at less than full capacity.'

The present application is a companion Vt-o mypending application Serial No. 564,626, filed May 29, 1922.
`In the emobodiment ofthe invention disf closed herein, the barkfcompressing machine includes a base 1 having feet2 for securing such base to a foundation. On the base 1 is. secured a cylinder 3 `having foraminous side walls 4 and foraminous top and bot-- tom walls 5 and 6, the top wall 5 being. providedwith an opening for the admission 4of bark to the cylinder 3. The cylinder is open at 8 for the emission ofbar-ktherefrom `adjustable members 9 in the side walls .4
for resisting the emission ofthe .bark from the cylinder 3. The members 9 are not shown or described in detail as they form no part of this invention `and are fully disclosed in my pending application Serial No. 564,626. The walls 4, 5 and 6.are secured together by tie bolts 10.
Reciprocable within the cylinder 3 is a piston 15 having a detachable foraminous head plate 16 and which is secured to the cross head 17vby rod 18, the cross head being reciprocable in the guide members 19. The cross head in turn is connected by crank rod 20 to reciprocating mechanism (not shown) but whichfmay be such as is disclosed in the above mentioned application, .Serial No.
564,626. Y E "The piston 15vis recessed and hasa' plurality-of verticallyextending partitions 21 and 22 dividing thev recess intochambers 23, 24 and 25 each having a bottom.V provided with apertures 26 adjacent the sides thereof and central apertures 27 Partitions 21 and 22 act as brace members adapted 'to absorb pressures upon ,the intermediate portion of plate 16 caused by bark compressed within the cylinder; The apertures 26 communicate are closed attheir front and rear'endsand y l at all times during the stroke of the piston 16 communicate with drain apertures 29 in the bottom f6 of the cylinder. The drain apertures 29 are connected by the channel 30 secured to the bottom 6 and communicating with the drain pipe 3,1.
Extending into each of the apertures 34 in the bottom 6 is a Water spraying nozzle- 35 each positioned for communication with an aperture 27 when the piston is in itsV retracted position relative to the cylinder. The nozzles35 are each connected to a common source of Water supply by pipe 36 and are at all times during'the reciprocation of piston 15 covered by such piston so that water coming from the nozzles will not vbe sprayed upon bark in the cylinder 3.V
At the open end of the cylinder 3 is provided a channel for guidingl the bark asit leaves the cylinder. This channel is provided with a bottom 46 substantially in alignment 4with the bottom- 61 in the cylinder and also with sides 47 substantially in align` ment with the' sidesy 4 ot the cylinder. This channel 45 isvsecured to the compressing machine by angularly disposed bolts 48 anchored at the sides of the base 1 and bolts .49 passing through the upper fianges of base 1.
Supported from and secured to the bottom 46 is a pair of vertically extending rods 50 each disposed adjacent one of the Walls 47 and connected at their upper ends by a pivot rod 51. Integral with the top wall 5 of the cylinder is a pair of spaced upstanding lugs 52 and connected at their upper ends by a rod 53. For securing the rods in their vertically upright position, a pair of links 54 are provided each connected with the pivot rod 51 and rod 53 adjacent the ends thereof.
Pivotally mounted upon rod 51 is a resistor jawV normally extending from rod 51 in a downwardly inclined position toward the open end kot the cylinder and provided with side walls 61 and bottom 62 curved upwardly at the free end 63 of the jaw. Supported from the top margins of walls 61 oit resistor jaw 60 is a transverse cross support 76 bolted to such walls. Mounted lon said support and integral therewith is a pair of spaced standards 64 connected by a pin 65 having a roller 66. Pivoted to rod 53 is an arm 67 having its pivoted end spaced itrom lugs 52 by bushings'S upon the'rod 53. This arm' rests uplonthe roller 66 disposedbetween the standard 64 upon the resistor jaw and is' provided at its free end with a weight 69 slidableV thereon and having a set screw member 7 0 for retaininb. the weight in any desired position .upon the arm 67:- For lim.-
i-ting .the extent .of increment ot the resistor jaw (tlinto' .the chaniel 4 5 ladjustable*bolts $6* are ,threaded .to-'portions of the `cross-sup"- ports 'Z6' progeotingi 'laterally upon sfide ofthe jaw 60 and are each adapted to contact with the walls 47 of the channel 45, thus the extent toy which the resistor member or jaw 60 may move into the channel 45 may be determined by the setting of bolts 7 5.
In operation the device operates as follows: lli/hen the piston 15 is in its retracted position as shown in Fig. 2 the bark is ted through the aperture 7 into the cylinder'. The piston, then in its forward movement, forces the bark toward the open end 8 ot the cylinder and the bark comes into contact with the resistance members 9 and the resistor jaw 60, which members and jaw tend to hold the bark within the cylinder. lt the pressure on such bark is not suilicient to drive it' past the resistor member or jaw when the piston has completed its forward stroke",l such piston will return to its retracted position' and additional bark be fed into the cylinder at which time the piston carries the additional bark forward into contact with the bark remainingv in the' cylinder and createsa' pressure suiicient to force some of the bark throiagh the opening 8 in the cylinder.
`When predetern'iincd` pressure on the bark has been attained the resistor jaw 60 will be moved upwardly about its pivot out of the direct path of the pressed bark to relieve such bark from any excess pressure.
The pressure created upon the bark by the piston and resistance members 9 and resistor jaw 60 will iorce l'luids in such bark to pass through the :t'oraminous walls of the cylinder and through the forannnous head ot i the piston. The fluids passing from the bark through the toraminous plate 16 upon the piston 15 will collect in the recesses 23,
and 25 in the piston head, som-e of the vfluid passing through the bottoms oil the several 5 recesses and into the slots 28 in the bottom ot the pistons.
is soon as the piston has completed its forward stroke it will then be moved to its retracted position wherein the apertures 2T in the bot-tom ot the recesses ot the piston register with their respective water sprayingnozzles 35 to permit water to be sprayed from the nozzles into the recesses.
sprayed' water will carry any ot' the solid fil-i5 matter that may have collected within the recesses by reason .of the pressingl operation, outwar 1Ily through the slots 28,. drain aperture- 29,`channel 30 and drain pipe 31, thus keeping the recesses clean and free from any solid matter. Y
It is apparent that any resista-nce which the resistor jaw offers tovv the emission of bark from the cylinder will be transmitted to the upper ends of the rods 50 through the pivot pin l51. To strengthen these rods 50 .and to maintain the pivot ott the resistor jaw in position, the links 54 are provided secured irc' the upstandng lugs the cylinder.
-The resistance that the resistor jaw may oder to the emission of bark from the cylinder may be controlled and predetermined by the proper adjustment of the Weight 69 upon the arm 67 which acts upon the standard 64 to force the resistor jaw into the channel 45.
The resistor jaw is curved upwardly at its free end 63 to provide a surface upon Which the bark may act to force the jaw upwardly when the resistance to the egress of the bark is of suflicient amount to force the fluids from the bark. l
While I have provided lan adjustable Weight for varying the resistance that the resistor jaw may offer to emitted bark, I have also provided adjustable bolts for limiting the extent to which the resistor jaw may extend into channel 45 thereby to determine also the initial resistance that the resistor may offer to the egress of bark from the cylinder 3 at the beginning of the bark pressing operation.
The cylinder and pistonioperating mechanism (not shown) are secured in relative position by the longitudinally extending tie rods SO which engage the apertured plate 81 at the open end of the cylinder 3. This arrangement is similar to the arrangement disclosed in my pending application Serial No. 564,626, and is not a part of this invention.
