MACHINE FOR MARKING OR ORNAMENTING CANDLES.

SPECIFICATION forming part of Letters Patent No. 471,991.,dated. March 29, 1892.

Application filed November 6, 1891. Serial No. 411,059. (No model.)

Pennsylvania, have invented or discovered a certain new and useful Improvement in Machines for Marking or Ornamenting Candles, of which improvement the following is a specification.

The invention described herein relates to ing or ornamenting candles, &c., and has for its object a construction whereby candles may be brought into contact with heated dies or type, whether inked or not, thereby impressing certain marks or ornamentation on the candles, such marks or ornamentation being brought out sharply by the stain imparted to the portions of the candles in contact with the dies or type.

In general terms the invention consists in the construction and combination, substantially as hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of my improved machine. Fig. 2 is a sectional elevation of the same, the plane of section being indicated by the line a 00, Fig. 1. Fig. 3 is a similar view, the operating parts being shown in adilferent position; and Fig. 4: is an elevation of a candle marked in my improved machine.

In the practice of my invention the candles to be marked or ornamented are placed in the trough 1, having inclined guideways 2,

down which the candles roll. At the end of the trough is formed 'a vertical slot 3, of a length and breadth a little greater than the length and diameter of the standard candle, for the passage of the candles down to the inclined bed 4. The movement of the candles through the slot 3 is controlled by a plunger 5, which is connected to a lever 6, pivoted at one end to a bar 7, its opposite end being raised and lowered by a standard 8 on the cross-head 9. As the plunger 5'i's raised a candle rolls into the slot and is forced down along the slot by the plunger as it descends. As shown in Fig; 2, theplunger as it descends closes the upper end of the slot and checks the movement of the candles along the trough 1. The movement of the candle down the slot is checked by springs 10, which will hold the candle until forced down by the plunger operating through the next candle, which rolls into the slot as the the depression 11, by an inclined spring-plate 15, over which an angular arm 16 on one of the fingers passes as the cross-head moves to the right. As the cross-head reaches the limit of its movement to the right, the angular arm moves off the plate 15 and permits the fingers to drop behind the candle, which is drawn up the rails by the fingers as the cross-head returns to the left, the angular arm passing under the plate 15. As the candle is drawn up the rails, it is shifted longitudinally by the guide-plate 17, attached to one of the side pieces of the machine, and by this longitudinal movement the opposite end of the candle is pressed against a spring 18, attached to the opposite side of the machine. Bythe combined action of the spring and guide plate 17 the candle is held from rolling down the rails 12 on the return movement of the fingers 13. The spring and guide so hold the candle that when the cross-head 9 reaches the right-hand limit of its movement the rolling table 19, carried by the cross-head, will be to the right of the candle, as shown in Fig. 3. This table 19, having a suitable cushion on its under side, is provided with a post or standard 20,passing up through an opening in the cross-head 9, and is free to move up and down therein. On the upper end of the post or standard is secured a cross-bar 21, whose ends extend over the side' pieces of the machine, as shown in Fig. 1. As the cross-head moves to the right, the ends of the bar 21 ride up along the springplates 22, secured, as shown in Figs. 1 and 2,

to the side pieces of the machine, thereby lifting the table 19 above the candle. The springplates are made of such a length and so 10- catedon the side pieces that when the table has passed to the right of the candle, when held by the spring 18 and guide-plate 17, the cross-bar2l will drop off the spring-plates onto the side pieces of the machine. As the crosshead moves to the left, the table will pass over the candle and in contact therewith, and as the rails 12 have an upward inclination and the upper edge of the side pieces of the machine are horizontal and as the parts of the machine are so portioned relative to each other that the lefthand edge of the table will just bear upon the candle, it is evident that as the candle is rolled up the rails 12 the table will be raised somewhat, thereby lifting the crossbar from the side pieces of the. machine and allowing the. entire weight of the table to restupon the candle. As. the table iscarried. along tothe left, it. rolls the candle over the type or die 23, which is heated in any suitable manner, preferablyby a shell or drum 24,.through which a heating-fluid is causedto pass and to which the type or die. is secured.

In order to insure thecandle being pressed with suificient force against the heated type or die, the, left-hand ends of the spring-plates 22,.under which the ends of the cross-bar move when passing to the left, are arranged over or in line withthe type or die. and are-so constructed as toexert a considerable pressure on thecross-bar and through that on the table. As the candle is rolled over the type or die, the portions of the candlewhich come in contact therewith are softened or liquefied, and such softened or liquefied portionswill: absorb or commi'ngl'e with the ink or coloringmatter onlthe type or die. As. the area and depth. of the. softened or liquefied. portions is sma1l,it will harden almosti'mmediately after the candle has been rolledaway from the type or die.

The ink or coloring-matter when used. is transferred from an inking-table 25, secured to the side pieces. at the rear end of the machine, to the type or die by aroller 26, which is mounted in a frame 27, connected by hinged bars 28 to the cross-head 9. As thelatter moves to the. right, the rolleris rolled over the table 25 until pins 29 on. the frame 27 pass upalong cam-plates 30 on the. side pieces of. the machine, thereby raising the roller slightly from theinking-table and holding it in such elevated position. until beyond the edge of the table. As the cross-head continues its movement to the right, the pins 29 slide down the cam-plates, thus lowering the inking-roller onto and permitting it to roll over the type or die. As the cross-headmoves to the left, the above-described movements arereversed. As therolling table approaches theleft-hand limit of its movement, the candle-isrolled oh? the type or die and onto the downwardly-inclinedrails 31, sothat the disrolling bed, which moves in a horizontal plane and the rails, constantly increases until the candle is free to roll down the rails to a suitable receptacle.

In lieu of inking the type or die, the latter may be made of copper, brass, or other metal or alloy, which will be attacked by the acid in the candles and form therewith such a compound as will be taken up or absorbed by the softened orliquefied material of the candles and stain or discolor the same. \Vhen such type or die is employed, the inking devices may be omitted.
