PAINT MIXING AND GRINDING wMACHINE.
SPECIFICATION forming part of Letters Patent No. 532,277, dated January 8, 1 895 Application tiled February 15,1394. j Serial No. 500,199. (No model.)
produce a machine of this character, wherein the paint is thoroughly mixed, and other force besides gravity is employed to feed the r 5 mixed paint to the grinder, so that the paint may be ground more quickly and finely than when the specic gravity of the paint, alone, is depended upon; wherein the force employed maybe doubled to double the quan- :o tity of paint fed tothe grinder in the same space of time, so that it may be ground and forcibly ejected Or discharged from the ma` chine, in about half the time employed in the operation first referred to, wherein the z 5 grinder is adjustable to regulate the fineness of the ground paint, and finally to produce a paint mixing and grinding machine which is simple, strong, durable, and inexpensive of construction. With these objects in view the invention consists in certain peculiar and novel features of construction and combination of parts, as hereinafter described and claimed.
In order that the invention may be fully un- 3 5 derstood, referenceis to be had to the accompanying drawings,vin which-'- y Figure 1. is a perspective: view of a paint mixing and grinding machine, constructed in accordance with my invention. Fig. 2. is a 4o vertical sectional view taken on the line os-- of Fig. .1. Fig. 3. is avertical sectional view taken on the line 'y-g/ of Fig. 1, and showing the grinding mechanism in elevation. Fig. 4. is a detail perspective view of the grinder.
In the said drawings, abox is formed with a flaring mouth or open end l, and a semicylindrical cavity 2,'forms its bottom or lower end; which cavity extends horizontally and transversely of the box. The box is also enlarged 5o semicylindrically at each side and above the semicylindrical cavity 2 5 which forms the op- My invention relates to paint mixing and grinding machines, and has for its object to positelydisposed and horizontal semicylin- . drical cavities 3 and 4. These cavities are interposed between and communicate with the mouth 1, and the cavity 2, and they also extend transversely of the machine. The center ofthe cavity 2, is positioned a little to one side ofthe medial line of the machine, for a purpose hereinafter explained. This box is .preferably cast in two parts; one part consisting Of a side and two end-walls, and the secured by screws or other suitable means,
upon a work bench, or in other suitable or convenient position. Extending axially through the semicylindrical cavity 3, is a shaft 8, which is j ournaled in the side-walls of the machine, and this shaft carries upon its projecting end,a handle 9,0f any suitable or preferred construction. Keyed,or otherwise rigidly mounted upon the shaft 9, and fitting so snugly within the cavity 3, as to almost touch the walls thereof, is a ribbed roller Or cog-wheel, 10. Extending axially through the semicylindrical cavity 4, is a shaft 11, which is j ournaled in the side-walls of the machine and keyed or otherwise rigidly mounted upon said shaft, andlitting so snugly Within the cavity 4, as to almost touch the innerl Walls thereof, is a ribbed roller or cog-wheel12, which meshes with the roller or cog-wheel 10.
Cast integral with, and projecting inward from the lower end of the side and upwardly from the bottom of the box, and centrally of the cavity 2, is a lug 13, and this lug is formed at its inner face, with a horizontal and transversely extending cylindrical cavity or` recess 14; said cavity or recess extending axially of the center of the cylindrical cavity 2. The detachable side of the box is formed with an outwardly projecting and conical shell or nozzle l5, which is concentrically arranged relative to the axial center of the semicylindrical cavity 2, and adjustably engaging a screwthreaded apertureformed in the outer end of the said conical shell, is a Set-screw 16, which IOO is longitudinally aligned with the center of the cylindrical cavity or recess 14. The shell 15, is also provided near its outer end and lower side with an exit opening or spout 17.
The grinder mechanism consists of the conical portion 18, whichfits within the conical shell 15,and the spindle or shaft19, which projects axially from the center of the cone, and engages revolubly at its free end, the cylindrical cavity or recess 14. The cone is formed at its opposite end with a cylindrical recess 20, which is engaged by the inner end of the set-screw 16; which thus forms one bearing, while the cylindrical cavity or recess 14, forms the other bearing for the grinder mechanism. Cast integral with, or keyed securely upon the shaft or spindle 19,is a gearpinion 21, and this gear-pinion engages or meshes with the ribbed roller or cog-wheel 10 alone; owing to the fact that its shaft 19 is located to one side of the center. Adjustably secured in a screw-threaded opening formed through the lug 13 in the adjacent side of the box, is a set-screw 22, and the in ner end of this set-screw bears against the adjacent end of the spindle or shaft 19. From this construction it will be apparent that by the proper operation of the set- screws 16 and 22, the annular space between the grinding surface of the cone and the grinding or inner surface of the shell 15, may be increased or diminished at will, so as to regu late or determine the degree of fineness to which the paint is ground.
In the operation of the machine, the oil and paint is poured into the open upper end or mouth of the box. The handle 9 is then operated, so as to turn the rollers in the direction indicated by the arrows, Fig. 2, and this rotation of the rollers not only thoroughly agitates and mixes the paint and oil, but also performs the function of a force pump, in precipitating the paint to the bottom of the box,because each rib of the inwardly moving rollers gathers a certain quantity of paint, and forcibly separating it from the mass in the upper end of the box, carries it downward and discharges it into the cavity 2 atthe bcttom of the box. These engaging ribs not only tend to force Vthe paint to the bottom of the box, but also operate to grind the paint from frictional contact, as will be readily understood. By the revolution of the rollers 10 and 12, the pinion 21, is also caused to rotate,and by revolving the cone 2S rapidly in the shell, the paint forced between said cone and shell by gravity and bythe pump action of the rollers, is ground thoroughly, and is discharged or ejected forcibly from the exit opening 17, into a paint bucket,or other suitable receptacle placed for the purpose below said opening.
- It' it is desired, without further adjustment of the grinding mechanism, to grind the paint more quickly and finely, the handle 9, is turned to rotate the rollers lO and 12, in the direction opposite to that indicated by the arrows, Fig. 2. This operation, instead of causing the teeth of each roller alternately to carry down a quantity of paint, causes each tooth of each roller to carry down simultaneously an equal quantity of the paint, so that with each complete revolution of the rollers, double the quantity of paint is carried to the bottom by the latter method of rotation than by the former, and as this paint must have an exit, it is compressed or forced more tightly between the revolving cone and the shell; is there more finely ground, and is more quickly and forcibly ejected from the exit opening 17 In this latter operation, the paint is also subjected to a grinding operation, owing to the proximity of the inner side of the semicylindrical walls forming the cavities 3 and 4 and the faces of the toothed rollers.
By forming the box, with the semicylindrical cavities d and 4, shoulders are formed at the junction of the said cavity end-walls, and the walls forming the lower end of the mouth or opening 1, and these shoulders tend to cause all of the paint to settle down between the rollers or cog- wheels 10 and 12, so that little or no paint can reach the bottom of the box without rst passing between said rollers, unless said rollers are rotated in the direction opposite to that indicated by the arrows, and this construction thereby insures a thorough mixing of all the paint placed within the machine.
From the above description, it will be seen that I have produced a paint mixing and grinding machine, which thoroughly mixes and grinds all of the paint in the shortest space of time, and which is simple, strong, durable, and'inexpensive of construction.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is y 1. In a paint mixing and grinding machine, the combination with a box, engaging rollers mounted therein, and a conical recess communicating with the lower end of said box, and having an exit opening, of a pinion rotatably mounted in the lower end of said box, and meshing with one of the first-mentioned rollers, and a conical grinding surface, iittin g in said conical recess, and means to actuate or rotate the conical grinding surface and the said rollers, substantially as set forth.
2. In a paint mixing and grinding machine, the combination with a box, a recess communicating with the interior of the box at the bottom, and ribbed inter-meshing rollers mounted therein of a gearpinion, meshing with one of the said rollers, a grinding surface actuated from said gearpinion, and means to adjust the said grinding surface, within said recess, so as to increase or diminish the space therebetween, substantially as set forth.
3. In a paint mixing and grinding machine, the combination with a box, having a recess IOO communicating with its interior, and a cylindrical bearing recess formed in the said boX, of a shaft mounted in said cylindrical recess, and having a grinding surface at its opposite end, and a set-screw passing into said recesses, and engaging a recess in the end of said grinding surface, and a second set-screw extending through a portion of the box and bearing against the end of the shaft, substantially as and for the purpose set forth. ,A Io
In testimony whereof I affix my signature in presence of two witnesses.
