ea/zdan A BY 7v V M United States Patent 2,991,575 TOY WHICH SlMULATES THE PERCOLATING ACTION OF A PERCOLATOR Charles Pearson, Jr., 396 Huntington L'ane, Elmhurst, 111. Filed Nov. 2, 1960, Ser. No. 66,859 6 Claims. (Cl. 40106.22)

This invention relates to a toy which simulates the percolating action of a percolator.

One of the objects of this invention is to provide a toy which looks like a percolator and which produces a simulated boiling water appearance, similar to that visible in conventional coffee percolators and the like.

Another object of this invention is to provide a simulated percolator and a simulated heating unit which are conjointly operated to produce a simulated percolating action in the percolator without heating the liquid therein.

Another object of this invention is to provide a toy which is safe, which is inexpensive, and which will provide a play action simulating that of heating a percolating unit, such as a coffee maker.

It is well known that children in their play like to utilize products in the kitchen which are used by the parents, therefore, it is an object of this invention to provide a toy comprising a simulated percolator and a simulated heating unit therefor, which when operated will cause the liquid or water in the percolator to appear as if it was boiling and percolating, similar to that of the conventional cofiee percolator. This action, however, is produced without heating the liquid or water and is perfectly safe for even the youngest of children.

Other objects will become apparent as this description progresses.

In the drawings:

FIGURE 4 is a view partly in cross-section taken on line 4-4 of FIGURE 2.

FIGURE 5 is a top view of the simulated heating unit, and

FIGURE 6 is a reduced plan view showing certain of the parts in the base of the simulated heating unit.

The simulated percolator is generally designated by the numeral 10 and the simulated heating unit is indicated generally by the numeral 12. The simulated percolator 10 will be first described.

The simulated percolator in appearance is like that of the conventional coffee percolator, except that it is smaller in size. The percolator includes a lower section 14, having a hollow body 16 closed at the lower end to provide a bottom 18 and open at the upper end. The upper end is closed by a circular plate 19 which is secured to the upper end of the body 16. A small electric motor, to be subsequently described, is secured within the hollow body 16. The simulated percolator has an upper container section 20 provided with a bottom wall 22 which rests on the plate '19 of the lower section. The upper container section 20 has a spout 24 at the forward end.

Supported inside the upper container section 20 is a housing 26 which is open at the bottom and rests on the bottom wall 22 of the upper section so that the bottom wall 22 completes the housing 26. Within the housing 26 there is a pump chamber 27 and a trough or channel 28 which leads from the pump chamber and extends forwardly thereof to connect with the column to be de- Patented July 11, 1961 scribed. The top of the housing 26 is closed, except for certain openings which will be described. The shape of said housing, pump chamber and trough is best shown in plan view in FIGURE 4. The housing 26 is secured in position by a fastening member such as a bolt 29. The upper enlarged end of said fastening member engages the top of the housing 26, with the opposite end of said bolt passing through suitably alined openings in the bottom wall 22 and upper wall '19, and secured to said bolt, as best shown in FIGURE 2, is a bracket member 30 which is supported inside the lower section 14.

A small electric motor 32 is suitably secured to said bracket so that the motor is supported in a 'vertical position, with the motor shaft 34 extending vertically through two alined openings of the two walls 22 and 19 and into the interior of the pump chamber 27. A propeller 36, preferably of four blades, is secured to the end of the motor shaft 34. The propeller 36 rotates within the pump chamber 27.

The top of housing 26 has an opening 38 in axial alinement with the motor shaft 34 so that the liquid within the upper container section 20, as will be subsequently described, can flow into the pump chamber 27. The top forward end of the housing 26 is provided with an enlarged opening within which is secured a tubular member 40.

Supported on said tubular member 40 is a generally convex shaped plate 42 which is provided with a series of spaced apertures 43, best shown in FIGURES 2 and 3. The plate has a central tubular shaped hub portion 44, the lower part of which telescopes over the vertical tubular section 40 and is secured thereon. A portion of the hub 44 extends upwardly of the convex shaped plate portion 42. The tubular member 40 and the tubular hub portion 44 form a column through which the liquid is pumped.

A closure member generally designated by the numeral 45 is removably positioned on the upper end of the upper container section 20 of the percolator. Said closure includes a convex shaped body 46 having a peripheral ledge 47 whereby same rests on the upper end of the upper container section 20. It is also provided with an enlarged annular opening within which is fixedly secured a transparent dome shaped member 48. The dome member 48 is in axial alinement with the tubular section 40 and the hub 44 of the plate 42, however, it has a larger radius. A handle 50 is secured by fastening means to the upper section 20 of the simulated percolator.

Secured to the bottom 18 of the lower section 14 of the percolator by suitable rivets 52 are electrical conducting members 54 which are shaped so that the upper portions thereof extend in a horizontal position and are spaced from the bottom of the percolator.

A pair of slideable contact elements 56 are slideably supported in the bottom of the lower section and said contact elements 56 pass through suitable openings in the bottom 18 and likewise pass through openings in guide members 60 secured to the bottom 18. Each of the slideable contact elements 56 is alined with the respective conducting member 54 and is adapted to make contact therewith when the percolator rests on the base or simulated heating unit 12, as shown in FIGURE 2. Each of the conducting members 54 is connected to the motor 32 by suitable conducting

wires

62 and 63 so that when the slideable contacts 56 are in the position shown in FIGURE 2 and the simulated heating unit, as will now be described, is on, the circuit to the motor 32 will be closed to operate the propeller 36. i

The simulated heating unit generally designated by 3 the numeral 12 includes a hollow base 66 of generally rectangular shape in plan, having an enlarged annular central opening 68 at the top and a central downwardly arcuate shaped lip 70 extending from the top towards said central opening. Supported within the base 66 is a simulated burner unit generally indicated at 72 which comprises an annular central portion 74 which fits within the annular opening 68 and extends upwardly thereof, as best seen in FIGURE 2, but below the plane of the top of the base. The simulated burner unit 72 has an annular recessed portion 76 to engage the underside of the annular lip 70 and then same extends horizontally outwardly and downwardly as at 77 and 78. It is secured to the base 66 by suitable fastening members 80.

- The central portion 74 of the simulated burner unit ,72 is provided with a pair of spaced oppositely positioned generally semi-circular shaped recesses 82 and 83, with an opening below each of said recesses. A generally semi-circular shaped plate 84 and another generally semicircular shaped plate 85, of metal or other conducting material is suitably secured in a respective recess. Each said plate has a metal contact point 84' and 85 to be engaged by a spring metal contact member which connects the plates electrically to the batteries.

A pair of dry cell batteries are supported within the base with their poles reversed. The positive and negative poles of the batteries are connected at one end, as is well understood. The other or front front ends are engaged by spring metal

electrical conducting elements

86 and 88 respectively. 7 Conducting element 86 is suitably anchored at the bottom as at 87 and extends upwardly and is curved rearwardly to make contact with the negative pole of battery B and then curves forwardly to make contact with contact point 84' on plate 84. The other spring conductor 88 is also anchored at the bottom as at 89, then is shaped arcuately as at 90 and then continues upwardly to make sliding contact with contact point 85' on plate 85. The spring conductor 88 is adapted to make contact with the positive pole of battery A through the arcuate section 90 when the cam member, to be described, is rotated to the position shown in FIGURE 2, and to break contact when the cam is in any other position.

A shaft 92 is supported at one end on a suitable bracket 93 secured to the base. The opposite end of the shaft extends through an opening in the front wall of the base and has an indicator knob 94 thereon. 'Fixedly secured to the shaft 92 is the cam member 95 which engages the electrical conductor 88 when the shaft 92 is properly rotated by the knob to move the arcuate section 90 of conductor 88 to make contact with the positive pole and close the circuit from the batteries.

The conductor element 88 forms the switch for the circuit. When the knob 94 is rotated to off position, the cam 95 will be out of engagement with the conductor 88 and the conductor 88 will not be in engagement with the positive pole of battery A and the circuit from the batteries will be open. When the switch is in on position, as shown in FIGURE 2, the circuit from the batteries to the plates 84 and 85 will be closed, hence if the percolator is placed thereon and the slideable contacts 56 engage the plates 84 and 85, circuit to the electric motor 32 will be closed through conducting members 54 and conducting

wires

62 and 63 to operate the motor. On the other hand, with the switch 88 in open position, that is, with the electrical conductor out of engagement with the positive pole of battery A, the circuit to the motor is open, even with the simulated percolator on the simulated heating unit.

With the simulated percolator on the simulated burner and the circuit to the motor closed to operate same, the motor 32 will rotate the propellers 36 within the pump chamber 27.

The liquid in the upper container section 20 of the 4 simulated percolator is filled to approximately the line 44 of FIGURE 2. The container section may be filled by removing the removable closure 45. When the propeller 36 is operating, the liquid in the container section 20 will flow through the opening 38 into the pump chamber 27 and will be pumped from the pump chamber forwardly through trough or channel 28 and upwardly through the tubular member 40, and up through the hub portion 44 which form the column. Due to the level of the liquid, only a certain amount of liquid is pumped to the top of thecolumn and after the liquid has been pumped the continuous operation of the propeller 36 will then pump air into the pump chamber 27 and column, since no more liquid is available for pumping. As the air is pumped in the column, the liquid within the column will percolate over the top of the column then drop through the perforated openings 43 of the plate 42 and fall back into the upper container section 20.

As the blades 36 continue operating the liquid within the upper container section 20 will enter the pump chamber 27 and will again be forced into the column so that all of the liquid within the upper container section 20 will be within the pump chamber 27 and the column simultaneously, and since during the cycle of this operation there will be no more liquid to enter the pump chamber 27, air will naturally be forced therein and this will cause the liquid in the column. to percolate over the top of the column. This operation is continuous so that as the liquid continues to percolate over the column it is visible through the transparent dome 48.

The percolating liquid strikes the interior of the transparent dome 48 and then drops outwardly around the apertured plate 43. The percolating action is clearly visible and simulates the percolating action of a coffee pot so that a very interesting and fascinating appearance is presented for the child. Obviously, the water is not heated in any manner but it does give the child the impression that the liquid is boiling and causing a percolating action, similar to the sight which he is familar with at home. The action is safe and harmless and all that the child has to do is to maintain the liquid to the level approximately that of the line 4-4 of FIG- UiRE 2, so that the percolating action can be effected.

It will be understood that various changes and modifications may be made from the foregoing without departing from the spirit and scope of the appended claims.
