' APPARATUS FOR MIXING COLORS.

Application filed March 6, 1914. Serial No. 822,909.

- Be-it known that I, OTTO Scnrrrz, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Apparatus for Mixing Colors, of which the'following is a specification.

This invention relates to apparatus for thoroughlym ixinga color solution for the purpjo'se'of infusingwith paper pulp and preventing-mottled effect.

' The apparatus employed for this purpose includes a tank adapted to receive thecolor solution and a valve connected to the tank for controlling the mixture. A water inlet pipe communicates with the valve so that when the valve is open the water will unite with the color solution at the junction of the The valve thus governs the color solution drawn from the tank and also the water inlet for diluting the color fluid. When the valve is open the water passing through the pipe will draw the color solution by-tlie suction created at the mouth of the valve -and the color solution entering at'this 'poi'nt'will then mix'with the Water to "give the required degree of saturrftion to the color. Heretofore clay or other ryfillt 1e colorsolutio'n in order to avoid the mottled effect. The ditliculty with this proeess has been that the fillers are sometimes obiectionable to'the use of the paper, and that the process is too complicated, necessitating the employment of expensive machinery. An-

other great drawback of this process is that a large percentage of the coloring matter is absorbed by the filler, resulting in a weaker, less perfect, dyeing.

The novel features of the invention are more fully. described in the following specification and claims and illustrated in the accompanying drawing in which:

Figure 1 represents a front elevation of an apparatus employed in carrying out this in'veption.

Fig. 2 1s a side elevation partly insection showing the valve open. Fig. 3 is a detail. view showing the valve closed.

In this drawing is shown an apparatus provided with a tank a for holding a suflicient quantity of color dissolved in water. This tank is equipped with a drain pipe 6 Specification of Letters Patent.

leading from the bottom of the tank to a valve 0. The valve is mounted to actuate in a casing (Z, and it is provided with inlet port e and outlet port I. The valve 0 carries a short section of a tube 9 which communicates when the valve is open as indicated in Fig. 2, with the lower end of the drain pipe I), while its lower end projects into the outlet port 7 of the valve. This short tube however could be omitted and the opening formed in the valve to register with the end of the drain pipe. A pipe having a water inlet h and a color,outlet 'i is secured to the valve casing and communicates with the valve. A handle or lever j is fixed to the valve 0 for the purpose of operating the valve. The color tank-a is secured to the apparatus by means of bands is. The water inlet pipe h can'be connected to a reservoir or other water supply while the color outlet pipe 11 leads into the paper pulp. The bottom of the tank is sloped or inclined toward the drain pipe so that no sediment fwill remain in the tank, and. is preferably covered with a screen.

It will be understood that the invention is by injecting a predetermined volume of water before the mixture flows into a paper pulp. By this method the paper can tinted toa uniform degree and the mottled effect is obviated. It also enables'the use of strong solutions of colors for coloring any paper where the mottled efi'ect is objectionable.

As shown in the drawing the water pipe is of larger diameter than the color'drain pipe so as to gage the proper proportionsof the mixture. The end of the drain pipe terminates at the lower port of the valve so that the color solutionwill completely mix by the sucking action of the descending Water created at the outlet of the pipe.

The tank a can be graduated as shown at m and in. this way it can be used to indicate the exact proportion of the color and the amount of water required to dilute the color.

-I claim:

1. An apparatus for mixing color solutions comprising a tank. adapted to contain a color solution, means for gaging the solution, a drain pipe connected to the tank, a.

water inlet pipe, a valve connection between the drain pipe and the Water iii'letfor caik trolling'the Solution and the'water;

2. An apgaratus for. mixing color 56111 tio i's comprising a. graduated tank arl'lpted' to measure and contain a 00161 solution, a drain pipe connected to the tank, a, water inlet p1pe,'said drain pipe being of smaller" diameter to Proportion the quantity of the 10 solution flowing from 'the'tank, a;va'lve coil nection between the drain pipe and the Water inletfo'w controlling the'seii'itiefi and thew'ater."

In testimony whereof I have hereunto set my ha'nd-in'the preeeiiee ef twmsiihee rieing 15 witnesses:
