UNITED STATES PATENT OFFICE HARRY L. CLARK, or NORWOOD,
AND JAMES H. SOWER, OF CINCINNATI, OHIO,
ASSIGNORS, BY MESNE ASSIGNMENTS, TO THE SOUTHERN OHIO TIN CAN COM- PANY, OF 'WINTON PLACE,
OHIO, A CORPORATION OF OHIO.
To all whom. it may concern Be it known that We, HARRY L. CLARK and JAMEs H. SowER, citizens of the United States, and residents, respectively, of Norwood and Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in aratfining-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, making part of this specification.
ur invention relates to processes and machines used therewith for coating and impregnating articles of absorbent nature with paraffin or the like. In particular, it relates to the impregnating of paper orfiber rolls, which are used for making containers, with parafiin, and the machine shown is one which was constructed for this particular purose.
p Broadly stated, the object of our invention is to provide a paraffining means for containers or other articles. which is rapid and efiic'ient, and which at the same time does not take up a large amount of space. In particular reference to the of paper rolls for containers or other rigid articles, our object is to provide for the articles themselves feeding throughthe de vice by pressure applied by the operator when inserting untreated articles in the machine. In connection with the process which our machine involves, it is our object to ass the articles first through a bath of mo ten material, and thence directly up an inclined passageway which is subjected to heated air, said air causing the paraflin or the like to sink into the article and become thoroughly impregnated and the surplus of the material to flow off from the article and thence down the passageway to the tank of molten material.
The objects above noted and other advantages which will be referred to, we accomplish by that certain process of treatment and that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

impregnating Patentediliov. 1, 1921. 1919. Serial No. 313,563.
Fig. 3 is a vertical cross. section taken through the heating furnacefor stove.
Fig. 4 is a detail top plan viewjof one of the conduits as it passes through the paraffin tank. According to our process, be treated, which in the particular form of apparatus shown, are'rolls made up from heavy paper or paper board, which are to be impregnated with paraflin, is passed first through a tank in'which' the paraflin is maintained in a molten condition. 'Without handling, the articles then are passed upwardly through any suitable conduit which is closed to the outside air, but through which passes, either by forced draft or natural flow, a Preferably this hot a1r, 1's provided by means of a direct flame, which is baflied to prevent its contact with the paraffin, but the products of combustion of which pass into the conduit.
The conduit should be upwardly sloping and of suflicient length so that all surplus material on the articles will melt oil and flow down into the tank again, and so that the hot air will cause the paraflin to sink into and become thoroughly impregnated in the articles. Another result of passing the articles in an upward slanting path is that all of the surplus materialwill flow off of the article, particularly in paper rolls, and furtherthe current of heated air carries ofi fully all'fumes which may arise as a result of cooking in the paraflin.
l Vith rigid articles, this method of paraffining has another distinct advantage, since the paraffin is itself a lubricant when hot, and thus there can be arranged a special form of conduit which will permit of the operator pushing along an entire line of the articles, in the movement of inserting uncoated ones in the tank, thus providing a stepby-step movement which is properly timed for complete impregnation. Then again the process involves no handling of the rolls, which is of advantage in connection with their use as containers for food products or the like.
The machine itself, in the embodiment shown in the drawings and the form developed by us for use in paraflining the paper rolls which go to make up bakmg powder cans, used in our business, has a the material to paraffin tank 1, under which is a compartthis connection, as at 2 in Fig. 1.
Adjoining the tank is a heating stove or furnace 3, from the far side of which extends a conduit 4, which opens into the inside of the stove, and extends upwardly at a slant a comparatively short distance, before it terminates in any desired form of chute, or conveyer for moving the rolls to a place for storage or to another machine.
At the base of the stove is a gas burner 5, and between the burner and the central portion of the. stove are three baffles 6, 7 and 8, which prevent the flame from the gas reaching the upper portion of the stove, and still permit the heated air and products of combustion to pass up through the stove and out through the conduit, the latter acting as a It is through the above described mechanism that the paper rolls pass, and it will be understood in the matter that follows that while the structure is particularly adapted to our purpose, any other open conveyer would serve, should the articles be of different character.
Dependent upon the width of the heating apparatus, there are provided the desired which in the particular instance are adapted to receive the paper rolls 10. They are formed with closed base and sides, and at the top are left open except for a retaining strip 11, which is held in place by interspaced cross strips 12.
' sides also,
In the base of the guides is placed a continuous round rod 13, which is an antifriction device, and if desired or necessary, this antifriction device could be duplicated on the other sides of the guides. adapted for use'with the particular guides will slide freely therein, since the round rod removes the frictien and the paraffin acts as a lubricant.
The guides run from the charging table 14 in a downward path through the tank 1, thence up throu h the stove and up through the conduit. Within the tank, the base and if desired, of the guides are pierced with holes 15, so as to permit the parafiin to readily coat on the articles.
In operation, the rolls are placed in the mouths 16 of the guides, which may have directing .fingers 17 and thence pushed along, so as to displace the roll in front. This is continued until the guides are completely full, when it is apparent that the additional rolls inserted will push one roll out of the end of the conduit. This step-bystep motion is well adapted to the work involvedsince the possible speed of work. of
The rolls the operator will move the articles along at El e proper speed for a complete impregna- As shown, the stove and the conduit have the upper ends in the form of lids 18 and 1 9, so that they can be easily opened up, should repairs become necessary.
The excess paraflin carried off by the articles as they pass from the bath runs down through the guides and into the bath. While direct hot air is employed, there is no flame which can reach the paraffin and explode or ignite it. The rolls are subjected to a constant draining during their passage through the conduit and the-guides, and thus emerge from the device with the paraffin thoroughly impregnated in the body thereof, but with a surface whichis only slightly greasy from the hot paraffin, and which dries without any surplusage showing.
Aside from the cheapness of operation and the speed of working, as compared to the older methods, requiring basket dipping, a large drying and kilning space, this device and method saves tremendously in paraflin.
So far as we are advised, no one in the past has considered that proper paraffining could be done by continuously passing an article from the molten bath to a place for ultimate storage, and it is because of the simultaneous draining and subjecting to heated air, that we are able to produce the paraflined article of perfect impregnation which We now obtain. In making paraflined paper containers, the method and device for carrying it out are especially convenient because the speed of the usual operator is proper for timing the subjecting of the paper to the process. As explained above, the omission of a belt or other conveyer with the guides in the particular showing is because with the article selected there is no particular need therefor.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:
