Application led June 28, 1923. Serial No. 648,191.
To all wlwm it may concern:
Be it known thatl I, EvALD J. ENoMaN, a citizen of the United States, and residing at St. Bernard in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Candle-Finishing Dies, of whichthe following specification is a full disclosure.
This invention relates generally to improvements in candle linishin machines, in which the candles after mol in are given a uniform size and smooth finishy drawing through finishing dies.
A11 object of the invention is the provision of a finishing die by the use of which superfluous grease or wax will be positively and completely removed from the candle, and from the finishing die after the candle is'drawn therethrough, producing a perfectly finished candle and insuring. clean uncaked dies after each drawin operation.
The above object is accomp ished by providing a finishing die having circumferential pockets within and at the upper end of the tapered die bore, one edge of each pocket acting as a circular scraper for assisting to uniformly smooth the candle as it is drawn through the die.
The features of the invention will be more particularl pointed out and the structure clearly d ned in the description of the drawings forming a part of this specification, in which drawings:
Figure 1 is a vertical sectional elevation through the heating chamber, one of the dies being shown in section, and
Figure 2 is an enlar d detail-section of the die and mounting trefor, onu line 2--2 of Figure 1.
The device or machine herein comprises a hollow casing 1, as a heating chamber, said casing havin formed integral4 therewith a pluralit o vertically disposed guide tubes 2, as die olders, traversing the chamber from top to bottom. At the bottom of the chamber are inlet and outlet ipes 3, 4, by which steam or hot water is introduced within and allowed to escape from the chamber, to heat the tubes 2 and dies 10 disposed therein, the structure and functions of said dies forming the main feature of this invention. Mounted upon the casing are vertical parallel guides 20, upon which guides is slidably mounted a carriage 21.
Attached to vertically downwardly from the bottom thereof are a plurality of lon shank hooks 22, one for cach die, said hoo s adapted to centrally traverse the dies 10 and to extend therebelow when the frame is in its lowermost position, to permit the candles, one of which is indicated at 23, to be hung by their wicks to said hooks. After han ing the roughly molded candles as shown, t e frame is raised by suitable means and the candles are drawn upwardly through the heated dies 10 for finishing or smoothing the candles.
Inasmuch as the dies are alike, the description will be directed to the structure of a single die. The die is of tubular form and has an outer cylindrical surface conforming to the bores of the guide tubes 2, and a truncated conical or tapered bore 25, upwardly convergent. Adjacent the top and smaller end of the tapered bore is formed either a single groove or a plurality of relatively spaced substantially semicircular grooves 26, as a means for cutting the surplus wax from the candle and disposing of the same while the candle is drawn through the die during the finishing opera tion. The upper edge 27 of each groove functions to scrape off the surplus wax and the wax ywill be temporarily received within the pocket formed by the groove. After the candle has left the die the melted wax the carriage and `extending I or grease will run out of the groove downwardly and preferably into a suitable drip rece tacle not herein shown.
Tlie upper end of the die is flanged as at 28 to limit its downward movement, to position the upper sides of the exterior circumferential' locking groove 29 flush withy the lower side of the heating chamber. By inserting locking strips 31 within grooves of adjacent rows or n s of dies, said dies are locked against clisplacement while the candles are drawn upwardly therethrough.
My improved finishing die provides means whereby all superfluous ease or wax is positively removed from t e candle, and an even, smooth, perfectly uniform candle obtained. The surplus grease is scraped olf and deposited within the'pockets formed by the grooves, wherein it is momentarily retained and thoroughly liquefied to cause the same subsequently to freely run out at the bottom of the mold, leaving said mold in perfectlv clean condition after candle withdraw Having described my invention, l claim:
l. A candle finishing die, comprising a tubular member having a tapered bore. said bore having a circumferential groove therein between the ends thereof'.
2. A candle finishing lie, comprising a tubular member having a tapered bore, said bore near its smaller end having a circumferential groove therein.
3. candle finishing die, colnprising a tubular member having a tapered bore, Said bore near its Ismaller end having a circumferential substantially scmicircula-r groove therein.
4. A candlefinishing die. comprising a tubular member having a tapered bore, said bore near its smaller end having a plurality of circumferential grooves therein.
5. A candle finishing die, comprising a tubular member having a tapered bore, said bore near its smaller end having a plurality ot' spaced circumferential substantially Seillicircular grooves.
6. A candle finishing machine, comprising a tubular finishing die having an upwardly tapering bore through which the candle is passed from below upwardly, said bore having at its smaller upper end a circumferential pocket for receiving surplus material as it is cleared from the andle, one edge of the pocket forming a circular scraper for uniformly scraping and finishing a candle.
7. A machine for finishing candles, cornprising a tubular die through which the candles are passed, said die having a pocket between the ends of its tubular bore for temporarily storing superfluous material, and means for heating said dies.
8. A machine for finishing candles, comprising a tubular die through which the can- ',dles are passed, said die having a circumferential pocket between the ends of its tubular assage for holding superfluous material during candle passa 9. A machine for nishing candles, comprising a tubular die through which the candles are passed, said die having a circum ferential groove for pocketing superfluous material.
10. A machine for finishing candles. comprising a tubular die through which the candles are passed, said die having a circumfcrential groove near its e-nd of smaller di` ameter, one edge of said groove. acting to uniformly scrape or finish the cande when said candle is drawn through said die.
l1. A machine for finishing candles, comprising a plurality of tubular finishing dies, means for drawing the candles through said dies from below upwardly, each die having an upwardly tapering bore, and having at their smaller upper ends a plurality of circumferential pockets for temporarily receiving surplus material, and acting as Scrapers for cleaning and finishing the candles.
In witness whereof, I hereunto subscribe my name, as attested by the two subscribing witnesses.
