" Application fil ed August 18, 1924. Serial No. 732,842.
This invention relates to "methods of and apparatus for working paper stock and has 7 1 For illustrative purposes the invention is herein shown embodied in a machineof the general type illustrated in my former-Let? ters Patent Nos. 1.302,469 dated April 29,
' 1919, 1,443,410 dated January 30, 1923, and
1,518,922 dated December 9, 1924.
My invention will be best-understood by reference to thefollowing description when taken inwonnection with the'accompanying illustration showing one specific-embodiment thereof. .while its scope will be more particularly pointed out in the appended claims. In the-drawings,' v Fig. .1 is an elevation, principally in longitudinal section, showing "a machine em bodyingone form-ofthe invention; 6
F igl 2 is a transverse sectional elevation on the line- 22 in Fig; '1; p v Fig. 3 is a similar section on the line 3,3 inFig. 1; Fig. 4 is a detail in plan tion of a scraper blade; and Fig. 5. is a side elevation showing the variable speed transmission and its relation to the refiner. 5 Referring to the drawings and to the embodiment of the invention therein illustrated, I have shown the same exemplified in a machine'of the type described in my aforesaid patents and application, the same having a 59 showing a por- 0 bodyor casing 7 provided with an internal cylindrical shellv 9 and carried b su1table supports 11 which rest on the plate 13. The casing is herein fixed, but the same might have a movement of rotation either 5 with or without bodily movenrent of the rolls hereinafter referred to. A housing 15 secured at one end of the casing contains within it an inlet chamber 17 which is surmounted by a hopper 19 through which stock 1 may be introduced, the latter in its passage to the casing being acted upon 'by'devices hereinafter described. 2
"During the operation of the machine the c stock travels from the inlet chamber through E the casing to a discharge chamber 21 secured to the opposite ends of the casing 7, there being provided at the bottom of the discharge chamber an outlet passage 23 through Whlch the worked over stock is discharged. In its travel through the casing the stock is subjected to a succession of reducing actions by some crushing agency and preferably by means of the heavy rolls 25. Any desired number of rolls may be provided, but herein the machine is equipped'with four.
The rolls extend lengthwise the cylinder and are adapted tobear against the stock distributed overthe inner face thereof, the rolls being carried around the inside of the cylinder by suitable supports outside of the same so that they are caused to move in a closed orbital path while acting to roll over and crush the stock.
To support and drive'the rolls the latter have ends of reduced diameter which extend 7 7 through the opposite end closures of the easmg and are supported in journal boxes 27 in which the] rolls are journaled preferably through means of roller bearings (not shown). Each journal box 27 is supportedl at one end of a short roll-carrying arm 29,- 4
the opposite end being pivoted on a sleeve or hub 31 fixed on the end of an arm 33 of a four arm spider 35 or roll-carrier which is keyed to the main drive shaft 37 The mainv drive shaft is supported in bearings 39; and
is driven by any suitable source of power -(not shown). Y
- The rolls are carried through their orbita path by the rotation of the two supporting an spiders 35 at opposite ends of the caslng driven by the. driving shaft 37. Itwillvbe observed, however, that each rollat each end' thereof is journaled in the end of. the arm 29 Y which is' itself pivoted on the rotary, rollcarrying spider, and in eccentric{relation to the shaft, so that the rotationof-the shaft and the carrier through centrifugal force acting on the heavy rolls, tends to swing the arm upwardly and move each roll toward the surface of the cylinder so that as the-shaft 37 is rotated, it carries with it the spiders 33 and the pivoted'arms 29in which the ends of the rolls. are journaled'. and "the latter are forced centrifugally out against the inner surface of the'shell while at the same'time they are carried bodily through aii'orbital path-within the shell. a T
a In a machine of this type it has been found desirable to impart by extraneous I described bodily movement through the position of which lengthwise the axes of Orbital path: It/is also often desirable toj'the cone pulleys may be shifted by means of have this rotary movement of the rolls take place at a speed corresponding to a rolling contact of the roll. on the surface of the stock. It may, however, be desirable at times to have provision for altering the speed of. rotation of the rolls to impart a slight slip thereto either backward or forward with reference to the stock over which the roll is traveling, or to avoid undue friction between the rolls and the shell when the rolls begin to wear.
The described method of supporting the rolls gives opportunity for imparting rotation thereto'either' at the speed corresponding to true rolling contact with the stock or at any desired rate of speed to get the required backward or forward slip by transmission gearingwhich is adapted, however, to maintain the same accurate intermeshing relation during any inward or outward movement of the rolls caused by centrifugal action. a
For this purpose each'roll beyond the outlet end of the machine has secured thereto a driven gear 43 which meshes with a. driving pinion t5, the latter fast onva short shaft 46 which is .journaled in the roll-carrying arm 29 and hub 31, the gears bein represented in Fig. 3 by their pitch lines on y'to avoid co'nfusion. As the rolls move toward or away from the inner wall of the casing the axis of the gear 43 moves in the arc ofa-zeir'cle about the axis of the gear 45,11 a center, so that the distance between centers remains the same and there is no alteration in the intermeshing relation of the two gears. To turn the gear 45' the shaft 46 has secured to the opposite ends thereof a driven gear 47 which meshes with a driving gear 49, the latter fixedl secured to a sleeve 51 mounted on the-driving, shaft 37 but freely rotatable thereon. The sleeve 51 is rotated in'one direction or the other, as the case may be, by any suitable means, as through the pulley 53, thereby impartin the required rotary movement through t e described gearing train to the rolls and giving the, latter the desired forward or backward slip, or true rolling contact, as the case may be, with reference to the stock being worked on.
To adjustably drive the pulley 53, and the described train of gearing, any suitable speed varying device may be employed, but
' herein (F ig.5) I have shown in conven- 5 from the lower pulley by a belt (not shown),
tional form a device similar to that disclosed in my application for patent Serial No. 661,418.
This comprises upper and lower reversely arrange cone pul eys 55- and 57 respectively, the lower pulley 57 being driven from the main drive shaft 37 through the pulley 59 and belt 61. The upper pulley 55-is driven a sliding frame (not shown) moved through anadjusting wheel 63. From the upper pulley power is transmitted to the ulley 53 and sleeve 51 by means of a crossed belt 65. By turning the hand wheel 63 the position of the belt with relation to the cones may be adjusted and the sleeve 51 may be rotated in either directionand at varying speeds. While I have herein shown and described for purposes of illustration "a conventional form of speed varying mechanism, other devices may be employed for this purpose as well as other forms of transmission gearing for rotating the rolls.
The described form of the invention being designed for continuous operation and for the progressive advance of the stock through the machine while being subjected to successive crushing actions, suitable feeding devices are employed. These herein comprise a series of devices which form in effect a mechanical screw conveyer acting to convey the material from one end of the machine to the other, thematerial bein advanced progressively between each crus ing action. In the illustrated example these "conveyer devices are in the form of inclined or helical vanes. 67 suitably placed to avoid interference with the rolls and herein carried by arms 69 projecting from hubs 71, there being four such vanes and arms for each hub, one between each adjacent pair of rolls. The conveyer as thus constituted extends lengthwise the drum and beyond the effective portions of the rolls so-that a number of vanes are located beneath the inlet 17 and thestock, as soon as delivered to the casing, becomes subject to the action of the conveyer.
Preferably the conveyer blades 69 are arranged with a gradually decreasing pitch from the inlet toward the outlet end, as. will .be clear from Fi 1, so that the rate of advance ofthe stoc through the machine diminishes toward the outlet. This provides for an increased number of crushings of the stock for a given length of travel as it nears the outlet end and compacts the stock more closely as the crushing operation rogresses. This not only secures a better gra e of stock and a more efiicient operation of the machine, but also prevents an undue wearing .of the. rolls'near the outlet end.
To prevent the stock from building up on the rolls I have provided. scraping devices for removing the material therefrom thesc being generally similar to those described in my afoi'esaid ending application. In the present form, iowever,'the scraping devices are in he form of bars 73 (Figs. 1, 2 and 4) having a beveled edge provided at intervals with orked projections #75 forming an open ended slot, the bars being held in slotted lugs 77 formed on the conveyer blade-carrying arms 69 and carrying bolts. which pass through the slots in the bars. Each scraping bar isclamped in the lugs "77 so that its edge comes into contact or approximate contact with the surface of the adjoining roll 25.
' While the supporting lugs normally hold the scraping bars in fixed relation to the roll the clamping bolts may be loosened at any time and the bar moved toward the roll' to compensate for wear in the roll. 'It will be 7 observed that the supporting lugs are angled so that this adjustment takesplace toward the roll rind outwardly toward the inner surface of the cylinder, so that, as the roll wears,
the adjustment of the bar is outwardly as;
well as toward the roll and a minimum adjustment of the scraper bar for any given wear in the roll is therefore required.
In order that the apparatus operatecontinuously and uniformly, it is" desirable that there be provided a continuous and uniform feed of the stock. For this purpose thereare preferably provided devices adapted to .take the stock as fast as it comes to the machine and deliver it evenly and uniformly to the inlet. In the described form of apparatus I have provided for this purpose intermediatejhe hopper 19 and the inlet 17 rotarydevices which are providedwith teeth or surface projections, such devices having their axes parallel with the axes of the rolls.
and being herein provided one on either sideof the inlet andpreferably driven at dif ferent speeds, their action being such as is adapted to break up the masses or bunches of stock and deliver it evenly and uniformly to the machine inlet where it is taken by the conveying devices 67 and del ivered'to the trolls.
Herein for this purpose I have provided at one side of the hopper 19,'immediately below the same, a rota drum, 79 provided with several sets of r ter being provided by toothed annular members 83 mounted on the drum 79 with suit,- able intermediate spacingmembers to separate the annular members each from the other lengthwise the drum. Thedrum 79 with its teeth 81 is cooperatively arranged with rela-' tion to a, similar drum 85 and teeth 87 also arranged below the hopper 19 andon theoppositeside of the path which the stock takes m passing from the ho per to the inlet 17. The teeth 87, however, lation to and slightly overlap the opposite teeth 81 so that the material passing tothe inlet is subject to the joint. action of both sets of teeth.
To render the device more effective for breaking up or shredding the entering stock. the two drums 79 and 85, which are rotated inthe directionindicated by the arrows in Fig.- 2, are driven-at different speeds. For
ial teeth 81, thelat ear a staggered re shaft 89 havin the frame-providedjournal 91'and the pn ey 93 which latter is driven directly through the belt 95 from the pulley 97 on the main driving shaft 37. Similarly thedrum carrying the pulley 101 which is driven by the belt 103 from drivepulley 105. One of the belts, as the belt 103, is crossed so as to cause the toothed shredding wheels to rotate in opposite directions but both downwardly in the direction of the entering stock, and the pulley 101 is of difi'erent diameter from that of' the pulley-93 to'provide for a difference in spee Preferably there are provided some means for clearing the'stock from the shredding wheels, such, for example, as a set of fingers .107, secured to the casing (see Fig. 2) and projecting between the sets of teeth 81 so as to dislodge the stock adhering to the drum between the teeth and prevent it from being carried around with the drum. A similar set of fingers 109 is provided between the. teeth 87 on the drum 85. The shredding wheels are capable of being operated at a hi h rate of speed making it possible to feed stock of high consistency to the machine and providing a steady'and uniform feed therefor.
The two sets of teeth moving downwardly, one past the other, tend not only to feed the stock uniformly but to "separate and break up bunches or masses of the same.
The inlet end of the machine is closed by an end closure plate 111 which is keyed to the shaft 37 and rotates therewith, the
is. mounted on the shaft 99 same being provided with openings through which the reduced ends ofthe rolls pass with suflicient clearance to allow the required radial inward or. outward movements of the roll. The periphery of the end closure 111 has a grooved joint with a casing 15 toprevent the escape of stock over the edges thereof and is also preferably provided with a series of deflecting blades 113 (only one'of which is shown in Fig. 1) which, coopcr-' end closure, the latter serving to force the stock away from the face thereof and cause it to pass through the outlet 23.
