Letters Patent No. 113,117, dated March 28, A1871.

IMPROVEMENT IN CANDLE-MOLDING. MACHINES.

The Schedule referred to in these Letten Patent and making of the same.

1'0 all whom it 'may conce/rn Beit known that I, JOSEPH WALns, of the city,

county, and State of New York, have invented a new and improved Candle-Molding Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.`

ing apparatus used for receiving the candles when lifted out of the molds, holding them till the nex batch is molded, and then removing them.

It also consists in certain details of construction in relation to the application of the molding-tubes to the supporting-plates, and to the introducing and drawing oli' ofthe 'water employed for cooling the molds, all as ranged it is necessary to employ a complete machine for each size it is required to make; consequently, the machines being quite expensive and there being'many different sizes required, the manufacture of candlesinvolves the investment of a large amount of capital iu machines, much of which I propose to save by constructing the machines so that they may be used for diereut sizes by slight changes being made.

In respect to the general arrangement of the machine, it is similar to others now in use, and need not therefore be described in its main features, which arel well understood. The rst part of my invention consists in the employment, with the piston-rods or pnshers A and the mold-tubes B, of two or more caps, 0,'according to and P of the boards K L M, will be separated for rethe number ot? dilierent sizes of candles itis desirable to make in one machine, which caps are detachably As the .candle-molding machines are at present ar;

connected to the pushers, and are to be employed one at a time with. each piston, being of different sizes, the smallest being of such size that when on the piston it will drop to the lower end of the mold, and fit in it there-so-as to close it to hold the melted substance for making the candles ofthe largest sizes.

The cap ofthe next greater size will be so as to fill themold, say, at two-thirds the way'down at G1, and stop there forl making shorter and lighter candles, and another size may be so las to lodge, say, half way down, as at O2, and make still shorter and lighter candles.

As many different sizes may be employed as required, and they will all be adjusted so as to produce, by the lling of the molds above them, the several standard .weights of candles, respectively.

These caps lare made in cast metal, inthe form oi' a cup, with internal screw-threads, and they are screwed on the upper ends'of the pistons,'as shown. They have a small hole through the bottom at the center, for the wick E to bedrawn up through them and the hollow pistons, as in other machines.

" In order to pack around the wick tightly to preventthe melted substance from escaping through these holes, Ipropose to introduce a sott India-rubber disk, F, with a central hole for .the work, between the bottom of the cap and the top of the piston, as shown, for pressing snugly against the wickby being screwed in tight to close the passage, but allow the wick to be drawn up, which it will do by reason ofV the soft and yielding nature of the material.

As the pistons will not fall so lowwhen the large capsV are used, the board G, by which they are lifted,

through the medium of the racks H and pinions I,

will bea'rrested sooner in the downward movement.

The improvement in the clamping apparatus for re-` ceiving and holding the candles after having been lifted out of the molds is as follows:l

The three boards or plates K L M are divided into three parts, N O P, and connected to end boards Q Q l Q2, similarly divided, and hinged at thee top, as shown at R, the middle pieces Q1 being arranged on the top of case S, so that the other parts on each side of them may swing toward a'nd fro'm them for opening and closing the holes-T, for the candles which are formed by the semicircular grooves in each of the parts along the wires on which the said boards are divided, which holes are coincident with the molds;-

The end pieces Q and Q have rods U 'jointed to them, which rods are jointed together at V, being of such-length that, when thel joint V-is moved down into the right line connecting the joints of the said rods with the said pieces, the latter, with the parts N ceiving the candles, the partsofthe board K being opened Ythe greatest amount, while those of board M will open but little, but the holes T in these being made larger, will insure the proper reception ofthe candles therein.

W represents endless elastic bands of any kind, connected to the pivots-by which the rods U are -jointed to .the boards Q Q2, Aso that they will be stretched when the rods are moved down to open the clamp,

but when the joints Vare moved above the right line Y the molds as shown, the one, a, being smaller, so as to pass through the hole forlb readily, and Asecuring them into the said plates.

This plan isrrnnch cheaper and simpler than the present mode of applying'anges or collars to the molds fortbe upper sides of the plates and clamping nuts on the molds below.

4The vspace A', between the plates X, is in practice alternately filled with steam for heating the molds to the proper condition for reception of the melted tallow and cold water for solidifying the same after the moldshayebeen filled. f' a Now, in making yshort candles according to my above-mentioned plan, in these long molds, it will not be necessaryto draw the water all'out of the said space for heating the molds, but only so far down as the molds are filled. I therefore propose to employ, in connection withthe pistons and caps arranged as described for making candles of different lengths, a glass 'or otherl transparent gauge-tube, B', arranged with the said space as shown, for indicating when. the water has been sufficiently drawn out, and thereby economize considerable time and water.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- 1.- The employment, with the molds and pistons, of

length of the molds, for making candles of different sizes in one machine, all substantially as specified.

2. The combination, with tbe caps C and pistons A, of the elastic packing-disks F, substantially as specitied.

3. The divided plates K L M of the clamp, having the semicircularnotches for clamping the candles con nected to the end pieces Q, Q1, and Q2, which are hinged together and provided'with the jointed rods U and the elastic bands or springs, all substantially as specified.

X bythe screw-threaded portions ab, substantially as specified. y V

A 5. The application, to the cooling and heating-tank of av candle-molding machine, arranged for making different sizes, as herein described, of the glass watergauges B', substantially as specified.
