I'm-MEI: OR MEL TO new A. FLUID.
Specification of Letters Patent.
Application filed June 20, 1813. Serial No. 774,988.
. A To all whom it may concern:
Be it known that we, Tnonms Tonnanon, Jonn Rowmnn Torrance, and HUGH Nssn Tonmcn, subjects of His Majesty the King of England, residing at Bitton, Gloucestershire, England, have invented certaln new and useful Improvements in Paint-Mills or Mills to Take a Fluid, of which the following is a specificah'on.
This invention isfor improvements m a paint mill or mills of a type suited or adapted to the grinding offluids or mixtures which become fluid after grinding, particularly of the type or mill consisting of an upper perforate grinding organ which forms'a receptacle for the fluid or like substance and the lower aspect of which forms a grinding surface: the other grinding surtace being a rotating disk which bears against the grinding surface of the receptacle. In the use of this type of mill the ground material exudes all around the area of contact between the grinding surfaces and it is collected and brought into a stream by a scraper or scrapers, or equivalent means bearing on the outside of the mill. Now such mills have hitherto been subject to serious disabilities and defects, disabilities and defects which tell pronouncedly when such a mill is used in grinding extremely fine colors such as for example with a gelatinous solution as in preparing a piment mixture for nse 1n the process of photographic carbon printing. If in such a as is referred to above the contact surfaces are arranged to fit closely at the margin or beyond the range of the leading grooves, the grinding will be slow, while a minute wear or gape at the extreme margin so efiect the mill as to render the grinding ineficient as the flow through will then become relatively rapid. As a consequence of these two contrary adverse conditions much time has necessarily to be spent in maintaining the mill in good adjustment as regards closeness of contact at the margin and the exact positions at which the leading grooves shall terminate. Further after the desirable adjustment has been efiected, a very slight amount of wear or use disturbs this adjustment so that mechanical treatment or repair becomes repeatedly necessary.
By and in accordance with the present invention the rotating and usually lower memher of a paint mill or to take a fluid as A further advantage realized by the present invention is that leading grooves may be largely, partially, or even wholly dispensed with: the tendency of coarse particles to escape grinding bein thus proportionately reduced, and the e ciency of the mill for fine grinding being thereby promoted.
The notation or wavering of the lower member of the paintv mill as carried out by appropriate mechanical devices which systematically change the direction of the successive nutationswill so distribute the Wear on the grinding organs that the operation becomes analogous to the grinding of an optical flat or an optical curve and the figure is preserved so that repairs are seldom or never required.
An obvious, convenient, and preferred methodof giving the rotating and usually Patented Feb. 23, 1915.,
lower member of a paint mill a movement of distributed or symmetrical nutation is by imparting thereto an orbital or planetary motion so that instead of running in true concentricity with its fellow stone it is dippins; in and out in a progressive manner.
The invention may be conveniently and advantageously carried out as shown in the accompanying drawings. W
In the accompanying drawings :Figure l is a central transverse sectional elevation of a paint mill according to this invention the section being taken on line at {B of Fig. 2. Fig. 2 is a side elevation. Fig. 3 is a plan view illustrating the scraper applied to the periphery of the lower grinding or like stone, and Fig. 4 is a plan view illustrating the scraper applied to the surface of the lower grinding or like stone. Fig. 5 is a front elevation partly in section of a modifiedform of paint mill according to this invention, and Fig. 6 a plan View thereof.
Figs. 7 and 8 illustrate in elevation and plan view respectively a detail of the paint mill according to Fig. 5 with the scrapers applied to the'periphery of the lower grinding or like stone. Fig. 9 is a sectional plan view taken on line a; w of Fig. 7.
As illustrated by Figs. 1 to 4 of the drawings the mill comprises two superimposed disk grinding members of suitable material, as stone, the upper disk 1 of which is stationary. Preferably the operating surfaces of these disks are spherical, the operative surface of the upper disk being concave while the operative surface of the lower disk 2 is convex, and this lower disk is adapted as depicted to be rotated about its own axis and at the same time as its rotates to be given an orbital or planetary motion thereby realizing a combined lateral and circular grinding action with a progressive dipping in and out of the lower disk which definitely assures the material being led or carried from the feeding hopper to the grinding surfaces and thence to the scraper or scrapers or equivalent and produces a cooling action by virtue of the surface of the lower disk being progressively exposed to the air.
The compound motion of the disk 2 may conveniently and advantageously be realized by fixing the same to rotate with a shaft 3 which is mounted in a swivel bearing 4 which allows the disk 2 to be rocked about the center of revolution of the spherical surface of the disk 2. T e lower end of the shaft 3 is rotatably mounted in a bearing 5 secured to the bevel wheel 6, whereby when such bevel wheel is rotated, the shaft is rotated about the central axis of the machine to thereby move the dial: 2 in an orbital path over the disk 1. The bevel wheel 6 is rotatably mounted on the spindle 7 on the base of the machine and is geared with the bevel wheel 8 secured to the shaft 9 on which are mounted loose and fast belt pulleys; rotation of the grinding member 2 about its own axis being effected by a gear wheel 10 rigidly secured to the shaft 3 and meshing with the stationary internally toothed gear 11.
In the above construction as the disk 2 has an orbital movement in relation to the upper disk 1 the scraper 12 (which removes the material operated upon from the periphery of the disk 2 and directs it into the chute 13) is adapted to have a corresponding movement so that it always remains in contact with the disk 2. According to one convenient arrangement the scraper 12 is carried by a rod 14 which is adjustably secured to an arm 15 mounted upon an extension 16 of the bush 4. The scraper 12 is rotatably secured to the upper end of the rod 14 so that it may be adjusted in relation to the disk 2 to be applied thereon with the necessary pressure, this adjustment being conveniently effected by means of the screw pin. 17 co-acting with the arm 18 secured to the upper end of the spindle. The said arm 18 is also mounted on the shaft 14 so that when desired it may be loosened to thereby allow the scraper to rotate away from the disk 2 such as for the purpose of cleaning. An additional scraper is preferably also utilized to remove the material operated upon from the spherical surface of the disk 2 during the interval of time it projects from one side of the disk 1. According to the device illustrated a scraper 19 is secured to an arm 19 mounted upon a pivot 20 stationarily mounted in relation to the disk 1. In some instances in'addition to the scraper being pressed upon the spherical surface 2 by its own weight it may be pressed upon such surface by the additional force of the spring. In order that this scraper shall not foul the sides of the disk 2 it is adapted to be automatically lifted after it has operated upon the projecting spherical surface of the disk 2 and is adapted to be dropped when the disk 2 again projects beyond the disk 1 at that side of the machine to which the scraper is fixed. This may be elfected by the rod 21 which is moved upward to raise the arm 19 and to retain such arm in its raised position until the disk 2, following its orbital path projects from the side aforesaid of the disk 1 when it is allowed to drop. To raise the arm a cam 22 mounted on the bevel wheel 6 co-acts with an arm 23 adjustably secured to the rod 21, such arm being returned and re tained in its lowered position by means of the spring 24.
In order that the disks 1 and 2 may be adjusted for fine or coarse grinding or to take up wear, improved means are provided. According to such improved means the stationary disk is adapted to be axially moved, means adjustably mounted in the machine frame being provided for forcing the stationary disk toward the co-acting disk and means being also provided for normally forcing the co-acting disk members apart. According to the form illustrated the hopper 25 has screwed engagement with the flange 26 the end of such feed hopper 27 engaging in a recess 28 of the disk member 1, so that by screwing the feed hopper 25 through the flange 26 by the handles 29 the disk member 1 will be forced downward toward the disk 2, the side projections 30 engaging in guides formed by the arm 31 constraining the disk 1 to have an axial movement only. The disk member 1 is normally mamas normally abuts against the end 27 of the hopper so that when the hopper is screwed downward it moves against the force of springs 32 and when screwed upward such springs 32 cause the disk member 1 also to move upward therewith.
The upper portion of the frame 31 carrying the disk member 1 and hopper 25 is adapted to be pivoted at 35 to the base of the machine, so that the upper portion of the machine may be swung back, such as to admit of the grinding members being cleaned, the pin 35 being removable to admit of said swinging movement.
A trough member 36 located below the disk 2 has the swivel bearing l securedthereto and is provided with a lubricator receptacle 37, and with an outer channel 38 for receiving the material operated upon which may'fall from the disk, an inter mediate channel being provided 'for the purpose hereinafter set forth.
The grinding disks may be water cooledmeans may not be incorporated. According to a convenient manner ofeffecting this the disks 1 and 2 are secured to castings 39 and 40 respectively, which are provided with chambers 41 and '42 for receiving water. The water enters the chamber 41 and passes therefrom to the pipe 43 from which it passes to the chamber 42. This chamber is provided with an outlet 43 which delivers the water into a trough 4-1 the water running away from such trough through the pipe 15. In order to conduct the water from the pipe 43 to the chamber -12 a pipe 46 passes down the hopper and has a ball and socket connection with the'member 47 passing through the disk member 2 and has also a ball and socket connection with a receiving cup 48 secured to the hopper, the pipe 46 thus being allowed to move with the disk member 2. This pipe 46 also acts as a stirrer for the paint contained in the hopper 25. In order to provide for the hopper being adjusted in the flange 26 the cup 48is mounted upon flat springs 49 which by being flexed compensatesfor the movement of the hopper and allows the cup 48 to be always maintained at the same distance from .the disk member 2. I
If desired the Water cooling arrangement may be modified so that the grinding disks or the like 1 and 2 may be heated such as by means of steam.
In the modified form of paint mill according to Figs. 5 to 9 of the drawings, the compound motion of the disk 2 is realized as before described by fixing the same to rotate with the swiveled shaft 3. The ball swivel 53 into each of which a proj eotion 54: secured to the spur Wheel 51 is adapted to engage so as to admit of the nutation or wavering of the shaft 3 and consequently also of the disk 2 and at the same time to permit rotary motion to be imparted to the said shaft by the spur wheel in the manner hereinafter to be described. The lower end of the shaft 3 is rotatably and slidably mounted in a footstep bearing 55 eccentrically secured to the spur wheel 56. The amount of eccentricity of the footstep bearing 55 in relation to the axis ofthe spur wheel 56 is preferably arranged variable, and to this end an appro-.
According t3) the scraper arrangement depicted the scrapers 7 0 and 71 which operate on the side and, top respectively of the disk 2 are carried by the shaft 3 through the medium of a sleeve 72 loosely mounted on by an arm 7 3the one end of which is integral with the sleeve 7 2 while the other end thereof carries a sleeve 74 to which is secured a rod 75 supporting the scraper 70 scraping or collecting relationship with the sides of the disks 2. The scraper 71 is fixed to a rod 76 pivotally mounted to the casing 67 at 77 and the other end of the rod 76 has secured thereto a rod 78 loosely mounted ball and socket joint fashion to an arm 79 integral with the sleeve 72.
v In order to facilitate the rotation of the spur wheel 51 the same is mounted on an antifriction thrust bearing 80 which is sup &
ported by a plate 89 supported by uprights "81 and perforated to admit of the passage of the shaft 3. V
As will now be seen a movement of nutation or wavering will be imparted to the disk 2 through the medium of the gearing 60, 59, 57, 56 and shaft 3 and at the same time the side scraper 70 will move in synchronism with the disk 2, and the scraper 71 will rise out of and fall into co-acting relationship with the grinding surface of the disk 2 in manner comparable to the action before described of the scraper 19. By the rotation of the gearing the shaft 58 and consequently also the mixers 64 in the container 63 and through the pinion 62 and spur wheel 51 the shaft 3 and with it the disk 2 will be caused to rotate; thus the disk 2 derives its compound movement of rotation and mutation or wavering.
In order that the disks 1 and 2 may be adjusted for fine or coarse grinding or take up wear the casing 67 carrying the disk,
7 85. On turning the hand wheel 84 the disk 2 is moved toward or away from the disk 1. Preferably springs 86 are interposed on the pillars 81 between the frame casing 67 of the machine .andthe casing 69, which are carried by these pillars. The disks are secured in grinding position by hand screws 87 bearing partly on the frame casing 67 and partly on the disk casing 67.
To permit cleaning or repairing or re- 7 newal of the disks the casing 67 is hingedly secured at 88 so that the said casing and with it the disk 1 can be swung clear.
. The arrangement as described of the gearing 51 and 62 afiordsfacilities for realizing a structure of great strength and rigidity and by a suitable provision of vertical walls 90, as depicted, to the plate 89 an oil bath for the said gearing 51 and 62 is obtainable.
While we have described the disk members 1 and 2 as beingsuperimposed it will be obvious that they may be arranged on their sides, in which case the beveled gears 6 and 8 maybe dispensed with and the bearing 5 may be secured directly to a belt driven ulley.
It is to be understood that the invention is not limited to the hereindescribed preferred embodiments thereof as variations therefrom without departing from the principle of the $5 invention and without sacrificing its chief 'aaasme advantagesmay be made, the described embodiments being those which so far we have found to give the best results.
