ART OF FILLING CONTAINERS WITH ICE-CREAM.

Application filed January 26, 1921.

To all whom it may concern:

Be it known that I, HAROLD C. HOWE, a citizen of theUnited States of America, and resident of Rutland, Rutland county, State of Vermont, have invented certain new and useful Improvements in and Relating to the Art of Filling Containers with Ice- Cream, of which the following is a specification.

This invention involves certain improvements in and relating to filling ice cream containers, and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanations of the accompanying drawings illustrating what ll now believe to be the preferred mechanical expression or embodiment of my invention from among other forms, constructions and arrangements withln the spirit and scope thereof.

It is an object of this invention to provide for packaging soft mushy ice cream in paper cans or other containers of a size particularly intended for domestic use, in an economical manner with waste reduced to the minimum, preparatory to the delivery of the packaged soft product to the hardening room.

A further object of the invention is to provide means for economically and conveniently packaging mushy or semi-fluid ice cream, in several flavors or colors from different freezers, in paper cans or other containers so that the several flavors or colors will be arranged in approximately distinct longitudinal columns in the containers with the several columns merging to form a solid block or body, all preparatory to the delivery of the filled containers to the hardening room for hardening to a marketable condition.

A further object of the invention is to provide simple and effective means whereby soft semi-fluid ice cream from the freezer. can be conveniently packed in vertically elongated containers such as paper cans, preparatory to delivery to the hardening room, without the use of pressure that Wlll cuase substantial loss in overrun or volume, and without substantial waste.

With these and other objects in view, my invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forth and specified hereinafter.

Specification of Letters Iatent.

Referring to the accompanying draw- 1ngs:-

Figure 1 is a perspective view of an ice cream container filling machine embodying my invention, the container carrier being shown in normal depressed position, two paper cans being shown in the carrier, one of said cans being alined with the filling tube or nozzle in position to move upward thereon preparatory to its downward filling stroke on said nozzle.

Fig. 2 is a side elevation with the parts in the same positions as in Fig. 1, the base being partially broken away and the pedal shown in section.

Fig. 3 is a vertical section.

Fig. 4 is a horizontal section taken in the plane of the line fir-4:, Fig. 3.

Fig. 5 is a horizontal section taken in the H plane of the line 5-5, Fig. 3.

Fig. 8 is a detail somewhat diagrammatii cal perspective view.

Fig. 9 is a perspective view of a filled paper can, partially broken away to show the block of ice cream composed of columns of difierent flavors.

The machine illustrated by the drawings embodies a longitudinally elongated depending or vertical filling tube or nozzle 1, formed to receive ice cream at its upper end and discharge the same from its lower end into the bottom of a can on the nozzle and to fill the can from the bottom up as thecan is moved downwardly on the nozzle.

Ice cream (which term includes water ice and other semi-frozen edible products) in a semi-fluid or partially-frozen flowable condition, flows into the upper end of this nozzle by gravity from any suitable source or sources, such as one or more freezers, or one or'more receptacles filled from one or more freezers.

This nozzle is formed with an imperforate exterior wall, tube or shell that in length preferably exceeds the interior length of the can to be filled thereby, that is exteriorly smooth or otherwise formed to permit longitudinal movement of the can thereon, that in cross'section exteriorly conforms to the cross sectional formation of the can to be filled of the nozzle so that the semi-liquid product can flow by gravity down from the open bottom end of the nozzle onto the can bottom and the can will be filled below the nozzle, from the bottom up as the can is moved down on the nozzle, whereby the can is filled exteriorly of the nozzle by the flowing quality of the cream, 2'. e. by the descending flowing column of cream after it leaves the nozzle and without pressure or forcing that will cause loss of overrun or volume. The can should be filled by the time its open upper end arrives at a position with respect to the lower open end of the nozzle to clear said lower end when the can is moved laterally across the same so that horizontal or lateral movement of the filled can to carry its upper end across the lower end of the nozzle will serve to shear off the column of cream at the lower open end of the nozzle.

The filling nozzle 1 is, in this instance, internally divided into several longitudinal passages toreceive cream of different flavors orcolors, each from its own source, so that the nozzle will simultaneously deliver from its lower end several columns of differently flavored cream that will flow from the lower end of the nozzle and into the can to unite into a single column or longitudinally elongated body made up of the longitudinal lengths of different-coloror flavor, approximately as indicated by the drawings although the form and arrangement and the number of colors or flavors can be varied.

In the particular example illustrated, (without desiring to so limit my invention) the nozzle is internally divided into three longitudinal passages, of uniform cross sectional capacity and each unobstructed or open throughout its length, by an interhal web forming three longitudinal partitions 1, radiating from a common center, and each imperforate, and in this instance, formed rigid or integral with the tubular shell forming the nozzle. The three passages are open at their lower ends at the lower open end of the nozzle, and in this instance, are so arranged that the body of cream in the filled can will be made up ofsector shaped (in cross section) longitudinal lengths of cream of different colors. However, the nozzle passages can be more or less than three and can be variously shaped and arrangedto produce various color arrangements in the completed body of cream.

In this example, each nozzle passage is at its upper end in. open communication with the interior of its own individual source of ice cream through the dischargeoutlet thereof, i. 6. there is provided a separate freezer or ice cream supply receptacle for each nozzle passage, three separate ice cream supplies for the particular nozzle shown. In this instance, without desiring to so limit all features of my invention, I show the nozzle 1 fixed to and, depending in downward continuation of a three-wayhollow union, nozzle head or shell 2, bolted or otherwise clamped to the underside of forwardly projecting elevated horizontal plate 3 forming part of a supporting bracket 4 fixed to the upper end of vertical supporting post This post rises from and is fixed to the horizontal table 6 of the hollow base or pedestal 7 of the machine.

The plate 3 is formed with vertical ports 3 (in this instance three in number) uniformly spaced apart around the longitudinal axial'line of the nozzle 1 and at uniform radial distances from said line, as appears from Fig. 4, although I do not wish to so limit all features of my invention. The union or nozzle head 2 is internally formed with'separate downwardly diverging conduits or passages 2, one for each nozzle passage, and these passages 2 at their upper ends terminate in vertical nipples 2 proJecting upwardly through the ports 3, respectively, usually a distance above the top face of plate 3. Each passage 2 and its nipple 2 constitute an upward continuation of the corresponding nozzle passage.

A separate ice cream supply is provided for each nipple 2", and in this instance, I show three separate ice cream receptacles 8 for this purpose. 7 Each supply receptacle is formed by a vertically elongated open-top can having a depending bottom supporting flange 8* resting on plate 3 within vertical top flange 3* thereof.

, Each supply receptacle 8 is formed with an ice cream supporting hopper or downwardly contracting floor 8 leadin to the bottom ice cream discharge forme by depending discharge mouth 8 adapted to depend within and form a slip joint connection with a nipple 2 In the form illustrated, the three supply receptacles are individually portable, and removably mounted on the plate 3, so that each receptacle can be lifted therefrom and placed under a freezer discharge and filled with ice cream and then placed in position on the plate 3 to permit ice cream to flow from the receptac e through mouth 8, passage 2 and therefrom into the nozzle passage in continuation thereof. Any suitable means are provided'to close the supply receptacle outlets while the receptacles are being filled from the freezer and transported therefrom to the plate 3. For instance, I show each aaeaeeo receptacle equipped with a cut off slide valve 8 operated across the depending mouth 8 to open and close the same. The cut ofl' is provided with an operating slide rod 8 movable through flange 8* and having a handle end accessible at the exterior of the receptacle bottom.

In operation, one receptacle will be filled from one freezer with, say strawberry flavored ice cream; another receptacle will be filled from a different freezer with, say,

vanilla ice cream, and the third receptacle will be filled with say from a third freezer.

However, I do not wish to limit all features of my invention to removable ice cream supply receptacles, as the supply receptacles, need not be provided with bottom out off devices and need not be removable, particularly as the supply receptacles can be filled while in the machine from elevated freezers orfrom buckets filled from freezers. Furthermore, the supply receptacles can be in the form of flared or enlarged upward continuations of the nozzle passages to form a divided hopper to reduce to the minimum bends and abrupt contractions in the passages between the nozzle and the main supply bodies of ice cream as the free downward flow of the cream is thereby retarded.

The several ice cream supply receptacles, and the several passages therefrom which are continued down through the nozzle, are so arranged as to provide for free downward flow of the several columns of ice cream by gravity, by reason of its flowable semifluid condition and the weight of, or the downward pressure of the atmosphere on the bodies of ice cream. To this end, each chocolate ice cream passage from the discharge end of. the nozzle upwardly including the'top enlarged ice cream supply portion thereof, is preferably of the same cross sectional capacity as the remaining passages and is unobstructed to provide, so far as possible, uniform simultaneous downward flow of ice cream in and from all three nozzle passagesduring can filling operations.

The machine, as so far described, presents afree-end nozzle fixed to and depending from the rigid plate 3, and spaced from post 5, and terminating a sufficient distance above table 6, to leave the nozzle unobstructed so that a cylindrical paper can, such as a (with its slip top cover I) removed) can be ap lied to the lower open end of the nozzle and slipped upwardly thereon to re ceive the three columns of ice cream descending from the three passages of the nozzle and. cause them to spread within tgie can to form a body of ice cream 0 af er hardening approximately as illustrated by Fig. 9 of the drawings. The paper can may be applied to, removed from, and

slipped up and down on the nozzle by hand. The can is slipped up on the nozzle to receive the cream on the can bottom at a greater or less distance below the open end of the nozzle. The can is then slipped down on the nozzle so that the cream fills the can from the bottom up as the can is withdrawn from the nozzle. The can preferably fits the nozzle with a running fit to, prevent upward leakage of fluid cream between the can and outer surface of the nozzle, and so that downward movement of the can tends to create minus pressure at the open end of the nozzle with a consequent suction action on the cream and acceleration of the downward flow thereof. When the can is filled and reaches the lower end of the nozzle, horizontal movement of the can from the nozzle shears ofl the column of cream. The cover I) is then applied to the filled can and the can is ready for the hardening room wherein the contents of the can are hardened for the market.

When the filled can is removed from the nozzle another can must be quickly applied thereto or some other means applied to the open end of the nozzle toprevent waste of cream. Ice cream as it comes from the commercial freezer is an exceedingly difficult material to control by mechanism, because of the differing degrees of fluidity of ice cream of different flavors under the same conditions, because ice cream drawn from one freezer will be of a diflerent degree of fluidity from that from another freezer and even different drawings from the same batch will differ in fluidity, because there is no certainty as to the degree of fluidity of the ice cream that the machine will be called on to handle, because a large proportion of air isnecessarily introduced into the cream in the freezer to produce over run and the required smooth product, and this over run must not be pressed from the cream before the same is hardened. In other words, the cream must be so handled after it leaves the freezer as to avoid loss of over run and consequent reduction in bulk or volume.

Sometimes the cream comes from the freezer in such a degree of fruidity as to flow quite freely from the supply reservoirs and nozzle passages, rendering it diflicult for an inexperienced person to fill, remove 'and apply cans to the nozzle without slopforcing pressure will cause loss of over run and reduction in volume.

Where the results attained by the filling machine of my invention are apt to be dependent an inexperienced operators, particularly operators, without experience as to the degrees of fluidity of'the cream best suited for filling cans with differently flavored cream, I prefer to employ mechanical means associated with the nozzle and cooperating with the paper cans during the operations of applying, filling and removing such cans.

For instance, I provide means for maintaining an approximately tight running fit between the can and nozzle to prevent upward leakage of cream around the nozzle, and particularly to cause the can to act as a reciprocating piston in association with the nozzle in driving air from the can on its upstroke and producing suction action on the cream on the can filling down stroke, and also means for carrying the cans horizontally to and from alinement with the nozzle and for moving the cans vertically on the nozzle, and also for preventing discharge of cream from the nozzle mouth (lower open end) during the intervals between filled can removal and empty can application with respect to the nozzle.

In the particular example illustrated, I show a vertical reciprocatory rod or slide 15, movable through the table 6 from a point below the same to a point above the same, and parallel with the longitudinal axis of the nozzle 1 and arranged a distance in advance thereof. This slide is guided by a post 16, fixed to and rising from table 6 ans having a longitudinal bore receiving the sli e.

On the upper end of the slide 15 is a head embodying a sliding ring or sleeve exteriorly fitting the nozzle 1 and a rotary can carrying turret. This head comprises a non-rotary horizontal plate 17 centrally receiving the upper end of slide 15 and fixedly clamped thereto. This plate 17 is circular in form although this shape is not essential.

The radius of the plate exceeds the distance from the slide 15 to the rear surface of the nozzle 1, and the plate is formed with a vertical opening receiving said nozzle. At this opening the plate forms a vertical sleeve 17 preferably provided with any suitable packing means 17 b at its inner surface. The sleeve 17 and its internalpacking 17 surround the nozzle 1 snugly with a running fit and is designed to reduce to the minimum air leakage between the sleeve and exterior surface of the nozzle on the downward sliding stroke of the sleeve on the nozzle.

The rotary can carrying turret is located below plate 17, concentric therewith and of approximately the same radius. This turret comprises a horizontal rotary top plate 18 at its top face slidably fitting the bottom face of plate 17. Plate 18 is formed with a central vertical hub receiving and rotatable on the journal portion 15 of slide 15. The slide 15 provides a shoulder at the lower end of the journal 15, on which the lower end of the hub of plate 18 rests so that said plate moves vertically with the slide. This plate 18 is formed with several similar uniformly spaced vertical openings 18 arranged to be successively brought into alinement and registration with the ring or sleeve 17 on rotation of the turret. The plate 18 is formed of substantial thickness around each opening 18 and the wall surrounding each opening is flared downwardly, see 18 (Fig. 3) to provide a paper can centering mouth. The diameter of the upper ends of these mouths or openings 18, is but slightly in excess of the exterior diameter of the nozzle 1 and the internal diameter of the ring or sleeve 17*.

In the particular example, I have happened to illustrate the turret is provided with three mouths or openings 18 spaced one hundred and twenty degrees apart, although of course the number of mouths and the spacing thereof is immaterial.

The rotary plate carries means to hold and support one or more paper cans a, in this instance, three, one for each mouth or opening18 The turret can be variously constructed to support the paper (or other) cans to be carried thereby although in the drawings I show the plate 18 provided with three depending hangers in the form of rigid vertical rods 20 at their upper ends secured to the plate and depending from the under side thereof. One hanger is provided for each month 18 and arranged just behind the mouth in the direction of rotation of the turret. Each hanger (rod 20) at its lower portion is provided with a can supportin shelf preferably having a free limite vertical movement on the rod and iii; yieldingly upheld to its limit of upward movement by a coiled expansion spring 21 confined on the rod by nut 22 longitudimally adjustable on the threaded end of the rod. The limit of upward movement of the 13,513 shelf is established by collar 23 vertically adjustable on the rod.

In the example illustrated, each can sup port or shelf, consists of a bracket having a hub or sleeve 24 slidable vertically on the 120 rod and a horizontally or laterally projecting fork 24* formed with a transverse can bottom receiving and can upholding"rfioor,. ledge or shelf 24. l

The arrangement of this can support is 125 such that when a portion of a can bottom is placed on ledge 24" (with the can held in an inclined position) and downward pressure is exerted on the can, the bracket carrying the shelf will be forced down against the pres- 130 sure of spring 21, so that it is possible to tilt the can to vertical position with its open end just below the mouth 18 above and that is alined with the support 24", 25 The operator then guides the open end of the can into said mouth and presses the same upwardly into the taper 18 or depends on the spring 21 to perform this function. The taper centers and slightly compresses the open end of the can and the can is thus held in position for vertical reciprocation and filling, by the bracket 24-24:".

When the slide 15 is in its normal lowered position (Fig. 3), the fiat lower end face of the sleeve 17 a is approximately flush with the horizontal bottom end face of the nozzle 1. The flat top face of the rotary plate 18 of the can carrying turret closely fits the flat bottom edge of sleeve 17 in sliding engagement so that the imperforate portions 18 (Fig. 6) interventing between the mouths or open ings 18 serve to close the otherwise open lower end of the nozzle 1 and hold back the cream therein while the turret is being rotated between can filling and can applying operations. With the parts in normal position, Fig. 3, a paper can is applied to a can support and its corresponding mbuth 18, as

before described, and the turret is rotated by a hand, a step forward, to bring said mouth and the can into registration with the sleeve 17 and the open end of the nozzle. The step by step rotation of the turret to always bring the turret to 'rest with a mouth 18 in proper registration with the open end of the nozzle, can be controlled by any suitable means, although I show depressions 18 in the top face of the rotary plate and a cooperating complementary spring pressed detent 17 carried by plate 17 for'thls purpose.

When the rotary turret holds an empty can a in alinement with the nozzle, Fig. 3, the head (in this instance consisting of the turret and plate 17) is elevated, usually by a quick movement, to carry the can upwardly on the exterior of the nozzle approximately throughout the length of the nozzle or until the can bottom more or less closely approaches the open end of the nozzle. This upward movement of the can on the nozzle serves to drive air from. the can either into the nozzle passages, or if so desired, through any suitable air escape by means of which air is exhausted at the exterior of the nozzle, or without driving into or through the several masses of ice cream. For instance, I show air escape duct e having lateral outlet to atmosphere at e controlled by any suitable outwardly opening check valve 6" that will close against air inlet. This air escape duct is shown (Fig. 3) with an open inlet end at the open lower end of the nozzle, the duct being formed longitudinally of and within the nozzle partition 1, and checkvalve-controlled lateral outlet in the nozzle head or union 2. However, I do not wish to limit my invention to any particular arrangement providing fou air relief, and for suction withdrawing action on the cream in the machine.

When the head carrying the can on the exterior of the nozzle has reached the desired limit of upward movement, to receive the cream from the three nozzle passages on the can bottom, the direction of movement of the head is thereupon reversed and the head is forced down carrying the can down on the nozzle so that the can is filled from the bottom by the cream below the nozzle and as the can descends. If the fit between the sleeve 17 and the nozzle and between the can and nozzle, is sufficiently tight or otherwise if the can is moved down with suflicient speed, a greater or less degree of minus pressure will be created in the can and nozzle, in fact, the head and can may be so manipulated as to exert a very strong suction pull on the cream in the three nozzle passages and the supply receptacles and greatly accelerate the can filling operation even though the cream is of a less degree of fluidity then usual. The desirability of utilizing this suction pull on the cream depends to a considerable extent on Whether the cream is flowing as freely and rapidly as desired. The head can be raised and lowered by manual power, b hand if desired, during the filling operatlon, and hence the speed of the can descent on the nozzle is under constant quickly-responding control so that the can may be stopped, started or its speed of movement varied during the filling opertion as may be desired to insure complete and uniform filling with cream from all three nozzle passages.

When the head reaches its limit of downward movement, the can filling operation is completed, and the operator thereupon rotates the rotary turret a step to shear oif the cream at the lower end of the nozzle, to close the lower end of the nozzle by a portion 18 of the turret plate 18, until the empty can on the next succeeding holder 243-44 is brought into alinement with the nozzle, and to bring the filled can to a position where it .can be removed from the turret by the operator. The operator removes the filled can by pressing the holder 24 -24 down against its sustaining spring until the upper end of the can is clear of the turrent mouth 18 whereupon the can is removed laterally from the turret. The slip cover is then placed on the filled can, and said can is ready for the hardening room.

The upper edge of the paper can, when in filling position (Fig. 3), is held snugly to the bottom edge face of the sleeve 17 and is accurately centered by the taper 18 so as to snugly fit the exterior of the nozzle when the can is forced upwardly on the ever,

- nozzle, and thereby reduces to the minimum duces to the minimum air leakage at the top edge of. the can during the downward filling stroke on the nozzle, for if so be so arranged to percan desired, the parts can mit air escape to atmosphere at the top edgeof the can during the upward stroke of the can on the nozzle instead of utilizing the air vent e for this purpose, while preventing inflow of air as before described.

Instead of raising and lowering the head (plate 17 and the turret) by hand, means can be provided for effecting and controlling these operations by foot ower.

For instance, I show the sli e 15 extended downwardly into the hollow base 7, and coupled to'Qretracing spring v 25 at its lower end coupled to the base. his spring constantly exerts its power to maintain the head at normal lowered position and to return the same thereto. The head is forced on its upward stroke andis controlled on its downward stroke, by a suitably fulcrumed vertically swinga-ble treadl 26, accessible at the exterior of the base and so connected with the slide '15 (as through chain 27 supported by pulley 28) as to elevate the head when the treadle is depressed. The operator can hence easily stop, retard and control the downward movement of the head and the filling stroke of the paper can, under the retracting power of the spring 25, by pressure of the' foot on the treadle. How- I do not wish to limit the broad features of my invention to any particular mechanism for operating the paper can carrying and controlling head, nor in fact to mechanism for manipulating and operating the can.

While I gain material advantages of great utility by providing means for filling cylindrical paper cans, yet i do not wish to limit all features of my invention to use with containers of cylindrical shape, nor to containers made of paper or like material, nor do I wish to limit all features of my invention to several supply receptacles and passages for filling containers with variously flavored or colored edible frozen or other semi-fluid products.

' It is obvious that various changes, modifications and variations might be resorted,

to, that features might be omitted or, parts added, without departing from the spirit and scope of m invention, and hence I do not wish to limit myself to the precise disclosure hereof in whole or in part.
