L. A. WOBBROOK APPARATUS FOR comma RBGEPTACLES WITH PARAPFIN. APPLICATION FILED JAN. 9, 1908.
9 315 Patented Oct. 13,1908.
unrrnn s'rl-rrns rarnn'r enr ch LEWIS A. WOBBROCK, 'OF MERTON, MINNESOTA.
To all'whem it may concern:
Be it known that 1, Lewis A; WOBBROCK, a citizen of the United States, residing at Merton, in the county of Steele and State of Minnesota, have invented certain new and art to which it appertains to make and use the same.
My invention has for its object to provide an improved process of and apparatus for coating butter tubs and various other articles with paraffin, and to this end the rocess consists of the novel treatment an the apparatus comprises the novel devices and combinations of devices hereinafter Clescribed and defined in the claims.
A simple and efiicient form of the novel apparatus, by means of which the novel process may be readily carried into effect for coating theinteriors of butter tubs and similar articles, is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.
Referring to the drawings, Figure 1 is a plan view of the apparatus. Fig. 2 is a section taken approximately on the line 00 of Fig. 1 and showing also in section a butter tub in position to receive an interior-coating of paraffin; and Fig. 3 is alsection taken on the line as as of Fig. 1; I
The paraffin, indicated by the character 2, is placed in a receptacle, preferably in the form of a conical metal basin 1, secured at its margin to an annular metal rim 2 which,
in turn,'is shown as supported by suitable legsB. The basin 1. is provided with radial ribs 4, preferably formed by bending thin sheets of metalinto U shape and securing thelewer edges thereof, at the ends of the ribs, directly to the concave surface of said basin, leaving clearance passages 4 between the said basin and the intermediate portions of the said ribs. At the inverted apex or lowest central portion of the basin 1 is a rigidly secured depending neck or sleeve 5, into which, as shown, is screwed a hollow threaded valve casing 6. A steam supply pipe 7 leads from a suitable source ofsteam supply into the lower end of the valve casing 6. This pipe 7 is preferably provided with a valve 8, by means of which it may be opened and closed so that the steam may be Specification of Letters Patent.
Application filed Januaryfl, 1908. Serial No. 409,918.
'APPARATUS FOR COATING RECEPTACLES WITH PARAFFIN.
Patented. Oct. 13, 1908.
cut off or supplied in any desired quantities, at will. A gravity seated valve 9 having an upwardly extended stem 9 and a depending stem 9 normally closes the passage through the valve casing 6. As shown, the up wardly extended stem 9 works through the hub of a transverse guide bar 10, shown as secured to' the lower end of the sleeve 5, while the depending stem 9 works through a similar transverse guide bar 11 secured in the valve casing 63.
The character 1 indicates a wooden butter .ub which, as shown in Fig. 2, is inverted and placed with its down-turned rim on the sup- .porting ribs 4, so that it directly overlies the valve 9 and is supported with clearance for the escape of air and steam between the lower edge thereof and the upper portion of the basin '1.
The operation of the apparatus described, in c'arryin out myimproved process, is as follows: The valve 8 being 0 iened more or less, steam under pressure will be forced u ward through the body of paraffin z and will vaporize and absorb or become 'commingled with the vaporized paraffin. The steam laden with parallin vapors will fill the inverted tub y and, coming into contact with the inner surface thereof, will deposit on said surfacev a thin layer of paraffin, which latter, upon coming intocontact with the tub, condenses and forms a thin coating over the entire inner surface of the tub. Any of the n that may condense, by the contact wi l tub, will run back into the basin 1, or if absorbed by the tub, will later evaporate, leaving the proper thin but evenly distributed coating of paraffin on the inner surface of the tub. The valve 9 will automatically open whenever the steam pressure exceeds the pressure of the atmosphere and of the column of parafiin, which latter is contained in the basin 1, but whenever the steam is cut elf or reduced below such pressure, said valve will automatically close, under the ac tion of gravity, and will thereby prevent the molten paraffin from running downward through the valve casing 6 into the steam supply pipe 7,
It wi 1 thus be seen that the process consists in coating a tub or other article, first commingling paraflin vapors with steam and thenv applying the commingled steam and parallin vapors to the surface to be coated. The steam also serves as the agent for meltthe steam is caused to pass through the molten body elf pai'a'fiin it absorbs or becomes commingled with the" vaporized paraffin.
In actual practice the improved process been carried out in a most satisfactory manner the novel apparatus above described, it may, however, be performed by apparatus of other form of construction.
What I claim is:
1. In an apparatus for coating butter tubs and other artiqles with parailin, the combination with a Basie, of a steam supply pipe leading into the bottom of said basin, and a check valve in the vicinity of the bottom of said basin. normally closing the steam passage the veto but adapted to be opened by steam pressure,substantially as described.
In testimony whereof I allix my signature in presence of two witnesses. LEWIS A. WOBBROUK. Witnesses:
