Application filed August s, 1926. Serial No. 126,836.

lhis invention relates to agitating and mixing in general, and resides in certain improvements in agitating and mixing-containers for such compound liquids as paints, enamels and the like.

Paints, enamels, and other compound liquids exhibit a well-known tendency to precipitate out the pigments, mineral ingredients, or other solidmat'ter held in a suspended coiidition therein, it their containers are left in stoage long enough. it is imperative, however, that when it, is applied "to the surface to be treated, the liquid have a uniform consistency, and that each cubic inch thereoi contain the same quantity of pigment as every other, else the protective and decorative purpose of the painting will not be accomplished at all.

At present, paints, enamels, and the like, upon receipt from storage or from. the manufactory, usually have to be prepared for use by stirring and mixing by means of a stick or paddle, which serves the purpose but poorly, particularly in loosening the solid matter i'roi'n the bottom of the can and mixing it with the base liquid. Consequently, also, a large amount of paint or enamel, as well as time, are invariably wasted, and, what is nore importan the resultingso-called mixture is not uniform and does not contain an adequate quantity of pigment.

i am aware that it has been proposed to provide containers in which liquids may be me chanically agitated and mixed, but such containers have been "found to be not susceptible of successful and economical manufacture, and the bulk 01 the paint or varnish used to day is sold in containers having no provision for mixing or stirring.

It is a prin'iary object of the present invention to provide a container for paints, enamels, and the like which shall have a sel contained mixer designed to effect thorough mixing of the paint, and so combined with the container as to render the whole of such a low production cost that it may be used for the packaging otthe smaller quantities of paints witriout raising the retail price appreciably above that of non-mixing containers.

A particular object of the present invention is to provide a container having an improved mixing elem nt, for example, one which can operate to screw into the more or ess coagulated layer of pigment at the bottom of the container when revolved in one direction to enter the layer, andto lift and distribute this pigment evenly throughout the base liquid when revolve-d in another direction, at the same time scraping the bottom and sides of the can clear of the adhering pigment in order to perfect the mixture.

A further obj ect of the present invention is to provide a mixing container, which upon its receipt from storage, can be operated to mix its contents, then opened, and later used, without the employment of implements other than those actually constituting a part of the mixing container itself.

The invention will be described in connection with the accompanying drawings, which illustrate a preferred embodiment and modifications thereof. In these drawings,

Referrii g now more in detailto the drawings by numeral, an advantageous embodiment of the invention is shown in Fig. 1 in its shipping or storage condition, and comprises a container-body or paintcan 1, having a detachable closure 2 of any suitable type,

here shown as the so-ealled friction-top type, the closure haying a welltop or having a depression therein, as shown. This closure is provided with a small central aperture or bearing hole 13 of a suiiicient size to permit a vertically extending metal red or warrior-shaft i to project through the opening. A flap-nut 3 screws down on the screw post 14 against a washer 11, and llQHt-E the cap-nut and the closure 2 constitute the container a fluid-tight recepacle whei these parts are thus a ranged, and thus all disengageable ports are secured against knocking loose; or loss ditiring shipn'ient, or st; clring, or storage.

As shown in Figs. 2 and 5, this element 7 is t specially ltorn'ied nieniber. being sul'isantially a ring with cut s extended and recurved, and is constructed to rest, when the container is being; shipped or stored, on its flat bottom side 17 on the top of the closure 2 around the cap screw 3, and locked thereon, thus constituting, the mixing container a unitary, rigid T his member 7 is hence protecteijl 7on1 accidental iilisplacenient, and can be reniord from its locked position only by the application of a horizontal force at one of its ends or by a direct upward pull. ..-;The member 7 is actually a continuation of the shaft 4.- and is a part thereof, and is con structed to be secured to the shaft l by means oi the threads 9 and Gas shown in Fig. 5, ll hen so joined, it then functions us a rank handle for the agitator shaft 4t and enables the agitator-head 5 to be rotated or oscillated in a horizontal plane, or lifted in a Vertical plane while being 01- tcillated or to have iinparted to it, any combination of these movements, successirely or siu'uiltaneously, to aid the scrai iing, grinding, and screw-pump ac tion of the agitator-head in eli'ectuating thorough mixing and preparing of the contents of the container.

Upon completion of a reasonable amount of agitatin and when it is deemed that the contents oi the can have been properly mixed. the can remaining unopened from the nioinent its purchase, during agitation, and until the brush is ready to be inserted into the coi'itainer or the liquid poured out the ag 'itater-shalt 4 with the blade-head 5 can be drz rn up by the inen'iber '7, until the bladehead 5 is in juxtai msition with the closure 2, whereupmi the ineu'ibcr 7 can be rotated until one of the blades 12 passes between the jaws oi the catch or support 10, whereby the shaft 4- and its head 5 are supported by the closure until the handle 7 turned back through an equal and opposite horizontal angle to disengage the blade 12 from the catch 10 in order .0 lower it into the bottom of the con tainer.

l i hen in the position shown in Fig. 6, the ineinlnn' 7 an be removed simply and quickly with one hand by applying tor f ue to it opposite in lirection to that necessary to screw it on. This operation can be ell'ected with one hand because the vertical part of the :atch 10 will pre 'ent rotation of the head 5 for more than one sector thereoil, no matter whether the screw threads 6 be left or right-handed, and the horizontal part of the catch 10 will obviate the nez'fessity oi" holding up the shaftby hand.

When the member 7 is removed, the wedgeshaped end 8 is ready to be inserted between the closure 2 and the container-body at any point on the joint thereof, and the member 7 elevated to loosen the closure 2, whereupon the closure may belifted off by the shaft 4, and resting on the blade-head 5, whereby there occurs no splashing or waste of the contents and no soiling of the operator or the surroundings, and whereby ready insertion and withdrawal of a paint brush is made possible without further manipulations, as the interior of the container is then occupied only by the liquid compound, having no obstructions whatsoever therein; or alternatively, the mixed contents can readily be poured out.

In Figs. 7, 8 and 9 is shown a modified containcr, the change lying chiefly in the agitator-operating, closure-removing means, comprising variations not only in the member 7, but in the member 4 as well. This modification contemplates a bend or goose-neck 41 at the upper end of the agitator-shaft 4- having a head 5 attached thereto in any suitable manner the end of the shaft being first thinned to a suflicient size to form a tenon capable of fitting through and engaging with a coinplen'ientary mortise or aperture 42 in the extended end i3 of the member 7 of the shaft at. This member 7 is substantially a ring in shape, and has a notch 44 for engaging with a tit or lug 45 on the surface of the cap-screw 3 in order to lock the section 7 against the cap-nut for shipping stacking, and storage, and thus the section 7 also constitutes a wrench for unscrewing the cap nut, well a crank-handle for the agitator and a closure-removeix The main purpose of this modification is to so decrease the cost of manufacture, without removing any of the novelties and advantages of the present invention, that the invention will be adapted for commercial needs.

In Fig. 10 is shown a mixer-element or agitator usable in containers of different sizes, and intended to be made independently of any particular container, the main feature of this modification being that it adapts the novel features of the agitator of the present invention to use with any shape or style of container. This modification comprises an agitatorhead or stirrer 5 attached in any suitable manner to a vertical rod or saaft 4 as shown in Fig. 10, which extends sufficiently far above the top of the container with which it is there being used as to enable the operator to complete the mixing of the contents eliieiently and neatly by grasping it and operating the agitator. This shaft is bent at its end to a right angle handle'51 as shown, and the extremity of this handle is wedge-shaped to serve as an opener, as hereinbefore described. By means of this modification, the improved and advantageous screw pump agitator-head can be placed in any container and used successfully therein without altering in any way the closure thereof, by merely removing the closure and inserting the agitator-element into the liquid.

This invention also contemplates, as a further modification, omitting the central screw cap opening in the main closure as shown in Fig. 11, thereby leaving the closure solid and integral, with the shaft formed at its upper end into a goose-neck as in Fig. 7, and abutting into contact with the underside of the integral'closure. In this case, however, the goose-neck is tapered and thinned from the apex of the right angle on out to the end, as shown in Fig. 11, instead of being tapered back on the shaft beyond the right-angle bend, as lIl Fig. 7 By removing the closure and hooking the ring-handle 7 which has been removed from the post 3 for the purpose, onto the goose-nech of the shaft 1", in the position shown in dotted lines in 11, the agitator can be e'fiiciently and easily operated. Th improved and advantageous screw-pump container of this modification thus enables the agitator-head to be placed and used in any container without altering the closure thereof.

By means of the container of the present invention, the mixing of paints and other compound liquids can be accomplished thoroughly and. quickly, and then the necessary parts can be removed for painting without any danger of the usual spilling and waste of the conten and soiling of the operator and surroundings. There are few manipulations required and thesecan all be performed with one hand. So simple and efficient is the con tainer that all these advantages are obtained without raising the retail price of the container appreciably above that of the subsistent types of non mixing container, decreasing the cost of manufacture being one, of the main results of the invention.
