' MACHINERY FOR MOLDING CANDLES.

I 3 Specification of Letters Patent No. 265, dated July 11, 1837.

To all whom it may concern Be it known that I, JosEPH H. TUGK, of Nantucket, in the county of Nantucket and State of Massachusetts, have invented an Im-- proved Machine for Molding or Casting Candles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the drawings which accompany and make a part of this specification.

By the use of this machine it is intended to mold a number of candles upon continuous wicks, the molded candles being drawn from the molds by means of machinery to be present-1y described, a fresh portion of wick being at the same time drawn into the molds, upon which fresh portion other candles are to be molded, and so in succession, until seven, eight or any other convenient number are molded which number will be governed by the height of the machine after which the candles are to be separated from' number of one dozen molds, the stands arefixed firmly on the lower rail of the machine, or on to the floor of the factory, as may be preferredQ The stands of molds are not provided with ledges to form a reservoir for the spermaceti or other material to be poured into the molds, excepting at their .back ends which may rise high enough for that purpose; but the side ledges are formed by what I denominate sliding shutters, which are shown at C, O, C, O, the lower side of which shutters lie and slide on the tops of the stands, their ends being confined down by the strips D, D, D,'under which they play freely.

Two of these sliding shutters are represented without the wick directors E, E,

above them, these being removed in order to exhibit the shutters and molds, the more distinctly. The sliding shutters taken slid in over the stands, have their inner edges exactly over the centers of the molds, and

there are notches or grooves made down these edges, colncidmg with the axis of each.

mold, into which notches the wicks are to pass, and where they are to be held while necessary, by means of the wick-directors in a way to be presently described.

Instead of the sliding shutters above described, I have sometimes used shutters, which are hinged to the edges of the stands, and which, when turned over upon them reach exactly to the middle of the molds, but I prefer the sliding shutters, and mention the others, for the purpose merely of showing how this part may be modified, as also various others, may be, without essentially varying the principle.

F, F, are two vertical levers, which operate upon two sliding frames, the sides of which extend along each side of the machine, and whose oflice is to move the sliding shutter and the wick directors as may be required.

Toeffect this, rods or pins, rise vertically from the sliding frame, the upper ends of which rods or pins enter holes in the sliding shutters, and likewise in the Wick directors, the'ends of these rods or pins are seen at a, a, a. Each lever moves two of the sliding shutters and two of the wick directors. The sliding frames are supported upon proper bars as ledges under the tops of the stands.

The wick directors E, E, are usually formed of plates of metal and the openings through them 5, Z), Z), I make in the ordinary form of a gothic window, the pointer arch serving to direct the wicks into the notches or grooves in the sliding shutters, and to hold them there during the molding process, while their wider parts are sufficiently large to admit the candles when drawn from the molds to pass through them.

The front edge of the reservoir is formed by a strip G which after the molding and when it is desired to remove the top cake may be raised or lowered by means of a lever H or in other convenient way so as to leave the reservoir open at the end- I I is a raising frame furnished with what I call wick holders J J K. The raising frame is used to draw the candles from the molds. The posts A, A, are grooved to receive tongues on the corners of the raising frame; or some other analogous means are adopted to allow the said frame to slide up and down correctly. This frame I usually raise and lower by means of a revolving shaft passing from end to end, under the middle of the frame.

of the frame. It has a pulley at each end around which the ropes 0, 0, pass and also around the pulleys (Z, (Z, at the top of the frame, these ropes being attached to the raising frame, it is held perfectly under command, there being a winch by which to turn the shaft, and a ratchet wheel and pawl to hold it in its place. If preferredthe shaft may cross the top of the frame, leaving the raising frame suspended below it, and it may then be turned by means of a rope passing around a pulley on its outer end.

Th wick holders J, J, K, consists each of three pieces, the middle piece K being equal in width to the distance between the centers of the two rows of molds in each stand over which they range. The side strips J, J, may

be of any convenient width, affording sufframe may be then lowered leaving the cani dles suspended and another set of wickholders may be attached to the wicks to renew theoperation. The candles are then to be separated from each other and removed from the machine. V

' I 'wind'the 'wicks'upon spools or bobbins,

which I prefer to place on rods at the back From these spools they pass down, andthrough smooth'holes prepared fo'r'the purpose in a plate'of'metal, by which they are conducted under the machine, where they pass around wires and up into the lower ends of the molds, which they fill sufficiently close, the small holes forming the lower ends of the molds are countersunk to take off the sharp edges.

I sometimes especially in warm weather, cool the molds artificially by the application of cold water. To effect this, I make the molds stand between the upper and lower plank into tight cisterns, taking care that the molds shall fit water tight, into these holes in the lower plank. I am thus enabled to surround the molds with cold water; and when this has become heated and requires to be discharged a fresh portion is admitted which flows down through a tube or trunk into the lower part of the cistern, which forces a corresponding portion of the warm water to rise and flow out through an opening, made for that purpose in the upper part of the cistern at the opposite end. The sliding frame for moving the sliding shutters and the wick directors may, in this case, pass on the outside of the stands the various connecting parts being so modifiedas to adapt them to this arrangement.

Having thus fully described the construction of my machine for molding candles, and having indicated the manner in which the respective parts thereof are intended to operate, I will here recapitulate the successive steps in which the process is carried on by its aid.

The wicks being wound upon spools are placed upon rods crossing the back part of the machine or are otherwise conveniently situated, they are then drawn upthrough the molds by means of a wicking needle and their ends confined by the wick holders, resting upon the rising frame, which must be sufficiently elevated above the molds to admit of the pouring of the melted stuff. into the reservoirs. In the process of wicking, the wicks before beingfastened by the wick holders are of. course passed through the proper openings in the wick directors. The strip Gr is made to close the endsof the reservoirs. The levers F F are .then so moved as to bring to slidingshutters', and the wick directors, into the proper position, the former covering one half the molds and the latter confining the wicks so as to stand in the axis of the molds. The material is then poured in and suffered to set, or is cooled by the artificial process (one person may attend a number of such machines, the material in the first, setting, while the othersare being filled). The bar G is then removed 1 and a topping knife is slid between the sliding shutters and directly upon the top of the stands; the blade being of the proper width to fill this space. To insure the removal of the'cake, the topping knife has a second blade parallel to the first, but narrower and a trifle longer the two blades being as far apart as the ordinary thickness of the cake; the end of the top blade is turned down so as to catch upon the cake in drawing it out. The sliding shutters and the wick directors, are then drawn back from the wicks, which places the openings in the latter directly over the candles, admitting the raising frame to be drawn up, and all the candles simultaneously drawn from the molds. These are elevated to such a height as is necessary to replace the sliding shutters and wick directors and to repeat and continue the process until the raising frame reaches the top of the machine.

In the above description I have supposed two stands only to be used in each machine but a greater number may be employed and operated upon by the same means.
