GEORGE E. PETERSEN, OF BRISTOL, PENNSYLVANIA, ASSIGNOR TO W'ILLIAM H. GRUNDY COMPANY. INC., OF BRISTOL, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

LIQUID-FEED REoEr'rAoLEf To all whom it may concern:

Be it known that I, GEORGE E. PETERSEN, a citizen of' the UnitedStates, and a resident of Bristol, county of Bucks, State of Pennsylvania, have invented a certain new and useful Improvement in Liquid-Feed Receptacles, of which the following is a specification.

The present invention relates to liquid feed receptacles, and more particularly to a receptacle designed and arranged to supply oil emulsion or any other liquid or fiowin material in uniform regulated quantities.

ome of the objects of the present'invention are to provide an improved receptacle for feeding liquid to a material or to any other point of use in regulated quantities; to provide a receptacle for feeding liquid uniformly and continuously throughout a period of operation; to provide means operating in conjunction with a liquid feed receptacle for varying the overflow level of the liquid contained therein; to provide an im proved liquid feed receptacle whereby all parts thereof are readily accessible for cleaning and replenishing purposes; to provide a liquid feed receptacle arranged to have av continuous tilting action to discharge the liquid therein at a predetermined uniform rate; to provide an improved liquid feed receptacle wherein the shape of the receptacle is such as to produce a constant uniform supply of liquid regardless of whether the receptacle is full or approaching an empty condition; to provide means for feeding a liquid uniformly and continuously regardless of the viscosity of the liquid or its temperature as influenced by the surrounding atmosphere, or the temperature in which it is used; and to provide other improvements as will hereinafter appear.

In the accompanying drawings, Fig. 1 represents a front elevation of an emulsion or liquid feeding machine embodying one form of the present invention; Fig. 2 represents an elevation of one end of the machine; Fig. 3 represents an elevation of the other end of the machine; Fig. 41 represents a rear elevation of the machine; and Fig. 5 represents a section on line 5-5 of Fig. 1.

Referring to'the drawings, one form of the present invention comprlses a liquid supply receptacle or reservoir 10, formed by end walls 11 and 12, a front wall 13, and

.of its open top construction, it is mounted for swinging movement on a rock shaft 15 which extends between the upper front portions of the walls 11 and 12 and has its pro ecting ends journaled respectively in arms 16 of end standards 17, which also carry rearwardly extending arms 18 for a purpose to be later described. This shaft 15 forms an axis of rotation for the receptacle 10 and it is so located as to be radially equidistant from the curved bottom 1 1. In other words, the center of curvature of the bottom 14 is coincident with the axis of r0- tation of the receptacle 10, so that there is a uniform movement or change of the liquid contents 'of the receptacle 1O whenever the latter is turned on its axis.

To discharge the contents of the receptacle 10, one or more discharge outlets 20 are formed by recessing the top edge of the front wall 13 so as to open into an inclined lip chute 21 or chutes. In the present instance, the receptacle is of the duplex type,

being subdivided by a partition 22 into two separate receptacles and hence two outlets 2Q with attached chutes 21 are shown, so it Wlll be understood that the invention is broadly to a single receptacle to which as many like units may be added as are required to serve the particular purpose to which the device is applied.

As a means. for causing the receptacle 10 to tilt so that it discharges its contents at a uniform predetermined rate, a rack 23 is fast to and extends substantially throughout the width: of the bottom 14: and in mesh which is journaled in brackets 30 secured to the standard 17. Preferably, the spindle 28 is arrangedto be connected to a driven stub shaft 31 through a clutch 32 whereby the worm 27 with its coacting parts can be disconnected from the main driving means, so amine receptacle can be tilted in'de pendently thereof for replenishing, clean ng, or any other purpose. The stub shaft 31 carries a worm wheel 33 in mesh with a worm 84- on a shaft 35, which carries a pulley 36 driven from any suitable source at a speed to properly g ive the tilting action necessary to proportion the feed of liquid for the purpose intended.

For the purpose, of causing the feed of the liquid to cease when the machine with which the receptacle cooperatescomes to a stop the shaft carries one or more inwardly extending arms 87 the number depending upon the number of re'ceptaclesin use, there being one for each, each 'ofwhich has a depending screw member 38carrying a liquid displacing body or float- 40. Under operating conditions, the shaft is in a position to lower the float 40 into the liquid a San cient amount to'cause the liquid level to rise to the overflow level of-the discharge outlet 20. To change the overflow level for inoperativeconditions, the shaft 15 is connected by av crank arm 41 with a rod 42 which is connected to a pivoted'bell crank 4:3 the other end of which is arranged in the path of two trip lugs 44 and on the throwoil rod 46 of the machine with which the liquid feed is used.

In the operation of the liquid feed the receptacle 10- is placed in its initial-starting position and filled with the desired emulsion or other liquid to be fed therefrom, and in such a. position the surface of the liqu-idfis at level. just below theline of the discharge outlet QOQand; consequently no liquid flows from the receptacle. When. it is desired to start the feeding, the rod 42 is movedin the direction to cause the floatdtl to lower the required. distance into the body of: the liquid so that it displaces asintwh of the liquid as is necessary to raise the level to overflow relation with respect to the discharge outlet 20, and thereupon the liquid flows by gravity down the. discharge chute 21 and flows or drips from the end thereof to the point of application to. the material or goods, which are to be impregnated or moistened with the liquid contents. Simultaneously with the lowering of the float 4.0, the power drive is thrown into. engagement andmotion transmittcdto the. shaft- 25, and thence by way of pinion 24 to an inch 23011 the bottom of the'rcceptacle 10 lYiththe starting of this feed. the pinion begins to slowly rotate the receptacle 101 in a direction to til-tthe receptacle about its discharge edge as an axis, and therefore insures a coin tinuous feeding of the liquid to the discharge outlet 20. This feeding of the, liquid can be controlled by varying the speed of rotation of the shaft, and it is customary to have such a speed relation between the shaft and the feeding speed of the material to which the liquid is to be applied so. proportioned as to supply exactly the amount of liquid requirec for moistening the material. The control of the feeding is such that in case it is necessary to discontinue the feeding of the material to the machine or. stop that machine for anyv purpose the feeding from the receptacle 10 will also automatically cease at this time as well as drip from the end of the discharge clhute. This takes place because upon the stopping: of the material feeding machine, the float on floats 40. will be automatically lifted out of the liquid: in the receptacle 10 so that the. level thereinYinr mediat cly falls by an amount equal. to. the volume of the aforesaid float, and this may be of course calculated with. an exactness which definitely gives a predetermined lowering of the level below. the month of the discharge outlet 20. Since the. tilting feed of the receptacle also discontinuesupon the stopping ofthe machine which feeds the material; there can be no further discharg ing of liquid until the aforesaid material machine. again comes into action, a1id as soon as this happens there is an automatic return of the float into. the liquid and the level thereof-raised; to. the discharge. point.

It will: now. be apparent that a complete unitary liquid feeding machine has been provided wherein it is. possible to. definitely PIZOPOItlOll the. liquid. flow in accordance with; the controlling conditions and. also maintain such proportioned flow as a uniform continuous one. lit will also be evident that since the receptacle for the liquid is. of open top. construction. it can not only readily be. replenishedwith fresh liquid when necessary. but also it is possible to have access to its interior for cleaning. purposes. without. dismantling anyparts of the machine or. izeipouii-ig .covers or otliicr acccsseries. generally forming a. part of? liquid feeding apparatus.

In connection with. the ordinary closed top liquid feeding devices, it is necessary to shut down thc. machine with. which the feeding device is used and remove many parts in order to gain access to the interior ofthe liq.- uid; receptacle. This makes it exceedingl difficult to readily change from one form of liquid to another because. it. is practically impossible. to con'ipletely drain. the contents oglithe receptacle, and. unless the entire structure. is. dismantled. the'rcceptacle cannot be cleaned to. receive. thencw or different type of nqaia;

VlZhile in the foregoing description there is a liquid feedv device. applicable to general llt) use and adaptable to many industries, it is desired to point out that the receptacle of the present invention is more particularly designed for use as an emulsion feed in the preparation of wool or any other material to be used in the textile industry, but it is to be understood that this is merely one use, and broadly considered the invention is equally applicable to the feeding of other liquids or solutions or for the purpose of feeding any material which is capable of a flowing or pouring feed. To those acquainted with the art, it is well known that in the worsted combing and spinning industry the wool and tops are treated with an oil or emulsion to facilitate the working process. This emulsion or oil treating of the wool has heretofore been carried out by cumbersome liquid feeders, involving the use of massive gravity controlled bodies or rotatable roll feeds which neither proportion nor uniformly control the feeding of the liquid to the wool. By the present invention, however, the defects and disadvantages of emulsion feeders are entirely overcome and eliminated, and a simple, compact feeding receptacle provided, the shape of which is substantially that of a quadrant so that the mass of liquid contained within the receptacle has a constant dimension with respect to the discharge outlet, and consequently delivers a uniform quantity of liquid to the discharge outlets and one which is OOntllllb one from full tank capacity until it is empty. Furthermore, by the present invention, the interior of the receptacle is accessible at all times, and its contents can therefore be entirely removed or completely drained whenever desired for the purpose of substituting another liquid Without disconnecting the device from the machine or taking it apart to make the necessary change. It will further be evident that the device of the present invention operates efliciently and equally well for light or heavy liquids and so functions regardless of the viscosity of the liquid. This feature is important because the viscosity of many liquids changes with changes of temperature, and consequently in prior types of feeding devices such change in viscosity immediatly effects a change in the rate of feeding, but in the receptacle of the present invention it is immaterial whether or not there is such a change in temperature as to alter the viscosity of the liquid, since this is automatically taken care of and the feeding maintained uniform throughout the operation.

Although but one form is shown in which this invention may be embodied, it is to be understood that the invention is not limited to any specific construction, but might be applied in various forms without departing from the spirit of the invention or the scope of the appended claims.
