3 Claims.

This invention relates to an apparatus for dispensing liquid materials and more particularly for formulating a colored paint from a plurality of colors.

In the paint trade it is uneconomical for a distributor to carry a large stock of ready mixed colors since the demand for many of them is relatively small. These little used colors often remain on the shelves for several months or even longer. The drying rate and other characteristics of many enamels are adversely affected by long standing and hence it would be very desirable to avoid such standing if possible.

. Most tints are prepared by mixing from 2 to 5 standard colors. Occasionally a special tint may require as many as '7v or 8 standard colors. It has been proposed to supply the distributor with the standard colors and when there is a call for a special tint to prepare it by mixing definite amounts of the standard colors according to the manufacturers specification. Many types of apparatus have been designed to accommodate contalners of the standard colors which could be readily mixed and poured into suitable measuring devices. The present invention relates to an improved device of this type which has many advantages over those heretofore used.

It is therefore an object of this invention to provide an apparatus which permits the ready combining of a plurality of differently colored paint or paint-like materials to provide the desired ultimate color. Another object is the provision of an apparatus which provides accurate control of the addition of differently colored finishing materials. Another object is the provision of an apparatus simple in design and operation, of low initial cost and upkeep, which obviates the need of stocking a large supply of ready mixed finishing compositions. A further object is the provision of an apparatus for preparing finishing compositions which eliminates spattering and splashing such as encountered in the conventional practice of manual pouring of tinting solutions in developing a required color. 0ther objects will appear as the description of the invention proceeds.

These objects are accomplished by means of an apparatus more fully hereinafter described which consists essentially of a vertical standard carrying a rotatable spider assembly positioned in a horizontal plane, said spider consisting of a plurality of members adapted to hold containers in a vertical or pouring position by means of cooperating supports fitted to the can sides.

In the preferred apparatus the standard consists of a heavy metal base plate supporting a rotatable vertical shaft to which is afilxed a spider assembly preferably fabricated from aluminum metal. The spider assembly consists of a plurality of bracket members adapted to support containers carrying finishing materials in a fixed vertical position or in a fixed pouring position where the can is tilted at an angle slightly greater than the horizontal. This selective positioning is accomplished by means of slots cut in the bracket arms so as to engage co-operating lugs on a can support. The can support consisting of a metal block is also recessed on the side opposite the lug to engage the can ears and carries a tapped threaded hole at the top to receive a bolt for clamping a removable can cover to the top of the can. The removable can cover is adapted to fit a conventional friction top can and is provided with a suitable vent and a knife type valve outlet. The cover is also designed with an opening at the center to receive the shaft of an agitator mixer to which a handle may be attached to permit agitation of the contents of the can interior.

Referring now to the drawings, Figure I represents a sectional side elevation of the apparatus and illustrates the complete assembly in which a paint can is suspended in a fixed vertical position in a spider bracket member which permits an adjustable positioning of the can for pouring purposes. This figure also shows the placement of a can in a spider bracket member which does not permit a change in can position but merely retains the can in a pouring position, an arrangement which forms a part of the actual apparatus in practice. Figure II is a detail drawing of the can design which is applicable for present use. Figure 111 is a detail view of the positioning pin arrangement for locking the shaft and spider in the desired position. Figure IV is a top view of the apparatus showing the alternate arrangement of spider bracket members for both adjustable and stationary positioning of the cans.

In the drawings, a support comprising a heavy metal base shown a l which carries-a rotatable vertical shaft 2 capable of being set at desired points by means of pin arrangement 3, consisting of a floating pin set on a small. spring so that the pin is forced into notches cut into the shaft collar 4, thus holding the assembly in the desired fixed position. Alternatively, the locking mechanism can be placed at the base of the spider assembly to permit rotation of the spider assembly while maintaining the vertical shaft in a fixed position.

The spider 8 consists of a plurality of bracket members at least some oi which are-designed to hold the can in a fixed vertical position and alternatively when desired in a fixed pouring position. This is accomplished by means 5 of slots 8 and 'I which engage lugs 8 and I (see Figure IV) of the can support 8. The can support I is recessed on the opposite sides to receive the can ears Ill and carries a tapped threaded hole at the top to receive the bolt I I which when 10 tightened fixes the can cover in position and holds the entire can assembly together. The can cover I2 is fitted with a vent II, a knife valve outlet ll and is provided at the center with an opening ll through which an agitator It may be inserted for agitating the contents of the can. The top of the agitator shaft is of square design to per mit the fastening thereto of a hand crank so that the material in the can may be stirred. The

stationary or non-adjustable arrangement of some of the spider members is shown by II which consists essentially of a bracket fitted with suitable hooks at the end of the member to hold the can in a pouring position. In operating the apparatus, round friction top "gallon cans of conventional design and containa ing the most commonly used color, namely white,

are fitted with the special can cover l2 co-operating with'the can support 9 and the assembly Other so compositions have been thoroughly agitated in the vertical position, the can assembly is lifted from the slot 6 and the can then tilted and slid into slot I which fixes the can in a rigid pouring position. A suitable weighing scale carrying a tared empty can is located conveniently beneath 40 the outlet valve I4. This valve is then opened to dispense into the can the required amount of material. The valve is then closed and the spider rotated to bring another composition of different color into proper position above the can on the scale and is locked into position by action of the pin assembly 3. Proper amount of material as provided by the formula is then added by opening the valve in the special can cover. The same procedure is repeated for the other selected colors on the apparatus until the ultimate color is obtained in accordance with the formula instructions.

The new apparatus is useful for dispensing liquid materials and particularly paint lacquer and. 5

resinous coating compositions containing coloring material where the demand is greater for a large variety of colors and where the ultimate color is pre-formulated and information thus made available as'to what tinting colors and amounts of eachare required to provide any ultimate color.

The invention is characterized by several im-' portant advantages. Particularly noteworthy is the more accurate control afforded by the new apparatus in adding the required amounts of tinting colors. Greater convenience is afi'orded and splashing and spattering previously encountered by conventional manual pouring from the can is eliminated. Economy in time and labor costs is provided by the new apparatus. Low initial cost and up-keep expense and simplified construction and operation are further advantages. Of primary importance is the removal of the former requirement that a dealer-distributor maintain large stocks of ready mixed colors to supply the varied demand of the consumer public.

As many widely different variations of the invention may be made without departing from the spirit and scope thereof, it will be understood that the invention is not limited to the specific embodiments herein set forth except as indicated in the appended claims.
