IMPROVEMENT IN AUTOMATIC FIRE-KINDLERS.

Specification forming part of Letters Patent No. 155,146, dated September 22, 1874; application filed December 18, 1873.

To all whom it may concern:

Be it known that I, EDWARD J. COSTELLO, of Quincy, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Automatic Fire- Kindlers, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being had to the accompanying drawing forming a part of this specification, in Which- Figure l is a side elevation of my improved automatic flre-kindler. Fig. 2 is a plan of the same, and Fig. 3 a view of the spring.

Like letters refer to like parts in the different figures of the drawing.

My invention relates to that .class of automatic lire-lighters which are operated by clock- Work; and consists in a novel mechanism for holding and striking the match, in combination with foraminous sheath or conductor for the train, all constructed and arranged as hereinafter more fully set forth, the object being to provide a simple and effective device for automatically striking a light or producing a fire at any xed time desired.

In Fig. l, A is the frame-work, to which the mechanism is attached; B, the friction-wheel, provided with the roughened surface D; and C, a floating lever or click having a fulcrurn at J. K is the escapement-lever having a fulcrum at x, and provided with the spring c, arranged Linder its short arm. The escapementwheel L (shown in Fig. 2, and also by dotted lines in Fig. l) is connected with the center arbor of an ordinary clock, or the arbor on which the hands are disposed, and is operated in the same manner of the alarm-escapement disk in an alarm-clock. G is an arm or projection, to which the perforated tube or train 7 E is hinged at y. This tube is made eXtensible, being provided with the sliding joint F. The wheel B is hollow or disk-shaped, and has a notch, f, and a shoulder or tooth, a, which is pressed against the end of the lever C by the action of a coiled spring, R, Fig. 3, disposed within the wheel, one end of which spring is attached to the frame A, and the other to the key-arbor P. On the side of the wheel B there is also a stud or projection, a', which strikes against the stop or stud b.

In Fig. 2, I is a rocking lever attached to the stud M by the fulcrum m, and provided with a spring, H, disposed between the lon g arm of the lever and stud, and acting eXpansively, thus forming a clamp by bringing the short arm of said lever in contact with said stud M between the fulcruln m and frame A. The wheel B is eccentric in form, the distance from the center of the same to the point z being greater than the distance to the point S, the distance from the periphery to the center gradually increasing from a, Where it is shortest, to z, where it is greatest.

From the above description the operation of my invention will be readily understood by all conversant with such matters, and is as follows:

A friction-match, d, being inserted in the clamp I, as shown in Fig. 1, the wheel L is attached to the arbor of the clock, and the spring 1t, Fig. 3, wound up by applying' a key to and turning the arbor l), Fig. 2, once around in the direction indicated by the arrow. On Withdrawing the key, one end of the spring being fastened to the back or fralne A, and the other to the arbor l?, on which the wheel B is secured, the expansive action ofthe spring will tend to uncoil it, thus turning the arbor P, and also the wheel B attached to the same, backward, or reversing the movement had in windin g, and bringing the shoulder a forcibly against the end of the floating lever C. To admit of this, the Wheel L must be turned or set in a position to elevate the long arm of lthe lever to such an extent as to throw the short arm out of contact with the lever C. Now, as the clock runs down, and operates to revolve thewheel L in the direction of the a1'- row, Fig. 2, it will be seen that when said wheel has been turned sufficiently to let the long arm of the lever K fall into the notch o, Fig. l, in said wheel, the spring c will, by its expansive action on the short arm of said lever, force it upward against the lever O, and disengage it from the wheel B, thus permitting said wheel to be rapidly revolved by its spring until the stud a comes into contact with the stop b, bringing the roughened surface D against the tip of the match d, which Will thus be ignited.

It Will be understood that the train or conductor E is to be inserted in the stove, and properly connected with the kindlin gs or fuel therein, which it is desired to have red at a 'given time, and that a fuse made of ordinary paper, or paper chemically prepared, must be inserted in the conductor E, one end of the paper being so placed that re Will be communicated to it from the match, and the opposite end so arranged as to communicate fire to the fuel in the stove.

It Will be seen that as the Wheel B revolves, the roughened surface D Will be brought into contact with the match with a constantly-increasing pressure, and then suddenly withdrawn, leaving it free to burn, the action on the match in that respect being very similar to what it is when lighted by hand.

The perforations in the tubular train E admit a sufficient quantity of air to maintain combustion, While at the same time the tube prevents the ame from being accidentally extinguished. A toggle-joint may be used at y to render the tube more adjustable, and any 4 required number of joints F may be used, as I have found that re may be communicated by this means to almost any distance.

I do not confine myself in the use of the mechanism described to lighting fuel in stoves, as it can be applied to many other purposes with equal advantage. The arbor I) can be easily connected With the stop-cock of a gasiixture in such a manner as to let on gas at any given time, which may be lighted after the manner described for lighting or communicating tire to fuel. My device is also useful for exploding mines, firing artillery, and for many other purposes Which will readily suggest themselves.

Having thus described my invention, what I claim is v1. The trippingdisk L, having the shoulder 0, and the spring-lever escapement K, in combination with the arm J, leve-r C, and eccentric igniting-wheel B, as and for the purpose Set forth.

l2. The combination of disk B with matchclamp I, and perforated conducting-tube E F, substantially in the manner and for the purpose specified.
