Description
June 22, 1965 F. A. PETTKOSKE MOLD'ASSEMBLY FOR MAKING CHEMICAL SPHERES Filed March 11, 1963 FIG. 2
FRANK A. PETTKOSKE INVENTOR United States Patent 3,189,947 MOLD ASSEMBLY FUR MAKWG CHEMICAL SEHERES Frank A. Pettltoshe, 8%19 Goif Drive, Spring Valley, Calif. Filed Mar. 11, 1963, Ser. No. 264,435 1 Claim. (Cl. 18-36) This invention relates to an apparatus for forming chemical balls with support means within for use as deodorants.
The object of my invention is to provide a mold assembly which will insure that the support means for deodorant chemical balls will be at the center of such ball. In such a manner the greatest use of the ball will be achieved. Heretofore, waste of materials has resulted from disengagement of a portion of the ball from its support due to the fact that the support therefor has not been in the center of the deodorant sphere. As the chemical wears away from the support means, there is no longer contact between the support means.
Other objects of the present invention are to provide a device of the above type which is of simple construction,
, inexpensive to manufacture and efficient to operate.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
FIGURE 1 is a cross section of my assembly showing relative positions of the elements immediately before force for molding is applied,
FIGURE 2 is a cross section of my assembly showing the relative positions of the elements as the pressure is applied,
FIGURE 3 is a cross section of the assembly after the molding operation,
FIGURE 4 shows a molding portion with a portion thereof cut-away.
Reference to the drawing showing the preferred structure and in which like numbers represent like parts, in FIGURE 1 the number 8 represents a semi-spherical mold portion perferably of steel and formed of body portion 4 cylindrical in shape with a hollow guide member housing integral with the body portion and extending from one end thereof. Within the housing in a parallel space relationship to the walls thereof is hollow guide member 6 projecting to the center of the hollow space within the semi-spherical mold portion. The hollow guide member is slidably mounted thereon. Said body 4 is retained in a projected position by spring means 14 working against stop 15, which stop is secured to the inner walls of housing 5. Stop 13 is secured to guide member 6 and abuts one end of said spring means as is shown in FIGURE 4.
Sleeve 2 surrounds said body 4 and retains chemical 5. Chemical 3 may be in a powdered, granulated, or flaked form and may be any chemical which will be cohesive under pressure and which will act as a deodorant for toilets and the like. I prefer to use paradichlor-obenzia.
Item 1 is an oppositely disposed semi-spherical mold element which is placed in position above the chemical for the pressure molding operation as is shown in FIG- URE 2.
Significant in my novel concept is the relationship of member 6 to support means 9. Said support means is preferably a looped wire which is a part of straight wire 7. The looped end of the wire rests at the end of member 6 and the remainder thereof extends through the hollow portion of member 6 into a spool not illustrated. In this manner the support means 9 will be retained at the center of a deodorant. Such retention is important for the maximum duration of existence of the deodorant. If the support means is not at the center of the deodorant a portion of the deodorant, upon wearing away, will fall from the support means and clog up the drains.
The molding operation is accomplished by body portion 4 being forced in the direction of arrow 10 of FIG- URE. 2. Not illustrated are mechanical means well known to those skilled in the art which abut housing 5 at a point 16 in order to provide the desired force.
After the deodorant is thusly formed with support means 9 in the center thereof guide member 6 is retracted in the direction of arrow 11 to the extent that the end thereof is flush with the recess portion of the mold portion at point 12. The deodorant 3 of FIGURE 3 may then be manually lifted from body 4-; wire 7 may be extended to the desired length, cut off and looped for the next deodorant ball.
Although preferred embodiments of the device are as illustrated and described, it is to be understood that further modifications and changes in the details of construction that may be restored to will fall within the scope of the invention as claimed.
What is claimed is:
In a mold assembly the combination of:
(a) a body portion cylindrical in shape one end of which is a semi-spherical shape.
(b) a semi-spherical mold element oppositely disposed to the body portion which, when together therewith, form a spherical mold,
(c) a sleeve slideable associated with the body portion for telescopic action therewith suitable for retaining the chemical to be molded,
(d) a hollow guide member telescopingly mounted within the central portion of the body portion,
(e) a housing secured to the end of the body portion opposite to that semi-spherical in shape and in which said guide member telescopically slides,
(f) a support member slideably mounted in the guide member formed from a wire one end of which is looped and which rests at one end of the guide member, and
(g) spiral spring means operatively mounted between the guide member and the housing one end of which means abuts a stop in the slide member and the opposite end abuts a stop in the housing member.
