SAMUEL ROBINSON, OF MONMOUTH, ILLINOIS.

AUTOMATIC FIRE-KINDLER.

SPECIFICATION forming part of Letters Patent No. 512,221, dated January 2, 1894.

Application filed March 3, 1893.

To all whom it may concern.-

Be it known that I, SAMUEL ROBINSON, a citizen of the United States, and a resident of Monmouth, \Varren county, Illinois,have invented certain new and useful Improvements in Automatic Fire-Kindlers; and my preferred forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

This invention relates to fire kindlers, and more especially to that class thereof whose operation and action are automatic as when controlled or tripped by clock mechanism, and the object of the same ,is to produce a fire kindler of this character simple in construction, positive in operation, cheap of manufacture, and not readily gotten out of order.

To this end the invention consistsin an automatic fire kindler constructed substantially as hereinafter described in detail, and as illustrated in the drawings, wherein Figure 1 isa generalperspective view showing the application of this device and on a smaller scale than the figures following. Fig. 2 is a side elevation of the post and devices connected therewith, and acentral longitudinal section of the match clamp and the scraper shown in its guides as ready for operation. Fig. 3 1s a perspective detail of the upper end of the post and the trigger. Fig. 4 is a detailed view of a modified form of trigger. Fig. 5 is a perspective detail of the match clamp, the guides, and the scraper. Fig. 6 is a perspective detail of the actuating weight and tripping mechanism therefor, aud an elevation Referring to the said drawings, the letter which a fire may be built.

P is an upright or post adjustablysupported from a suitable base and carryinga spring arm. T isa trigger at the upper end of this post for holding the upper end of the spring arm as shown in full lines in Fig. 1 and for releasing it as shown in dotted lines.

M is a clock or other actuating mechanism adapted at a predetermined moment to release a weight Wwhich is connected with said trigger, and R is a roughened match- Serial No. 464,495. (No model.)

scraper connected with the arm and adapted to move in guides overa match clamp O which is detachably mounted in the stovethese parts being severally of the following specific construction or of such similar constructions as will produce the same general'result.

The stove S has a front door 1 within which is cut a slot 2 through which the scraper R may slide; otherwise this stove is of the usual construction and needs no further explanation.

The upright P consists of a post 10 having a number of holes 11 through its lower end, through any of which may be passedascrew 12 which takes in it a support 13, whereby the height of the post can be adjusted to suit different stoves.

Connected with the post by suitable means, as rivets or screws l4t,'is a spring-actuated arm 15 standing on the rear side of the post and having its body bowed outwardly as shown and its upperend 16 vertical, and 17 is a wire or light chain connected with such upper end and passing thence througha hole 18 in the post to the scraper R described below.

' The trigger T comprises a short arm 20 having an eye 21 pivoted on a vertical rivet or pin 22 between cars 23 on the rear face of the post 10 and adapted to stand across in rear of the upper end 16 of the spring, and a trip having an eye 31 similarly pivoted on a rivet 32 between ears 33.0n the postthe heel of this trip having a notch 34 adapted to engage the free end of the arm 20 when the bodies of the trip and arm stand in alignment. The upper end of the post has a lateral extension 19 provided with a hole 19', and 35 is a wire or cord connected with the free end of the trip and passing through this hole 19 to the clock or other actuating mechanism M. Y

The modified form of trigger shown in Fig. 4 possesses an arm 20 with a notch 21' in its free end, and the trip 30 is L-shaped and any desired ioo construction, and considerable latitude must be allowed the manufacturer in this respect. I have referred to it as the actuating mechanism by which I desire to be understood as including any of the well known forms ofsuch mechanism, as electricity or a clock driven by any form of power whatever, so long as it possesses a shaft rotated at a certain predetermined speed. In Fig. 6 I have shown such shaft 40 whereon is mounted a wheel 41 having a rim 42 provided with a notch 43, and when the shaft is turned so that this'notch comes under the weight described below, the latter will drop and ignite the fire. I do not wish to limit myself to this form of. tripping device, however, nor even do I desire to be understood as in all cases connecting the shaft 40 with clock mechanism. This shaft might be arranged to be turned as by the drawing of a bell wire from a remote point either manually, by the rising or fall of a float in a tank, or by any other agency whatsoever. The weight W is also susceptible of considerable modification. In my'preferred form of weight, 50 is a square vertical rod having an enlarged head 51 at its lower end and standing adjacent to the rim of the wheel 41; and 52 is a weight having a hole 53 fitting loosely on this rod and provided with a pin 54 in one side which may be of a size to pass through the notch 43 or which preferably carries a roller 55 sustaining the weight by traveling on said rim and capable of dropping through the notch at the desired time. The weight is connected with the cord or wire 35 as shown. The actuating mechanism and weight may be located within the base 13 which would then be a box for this purpose, but in Fig. 1 I have shown the said mechanism at some distance from the stove. The mechanism could be an ordinary alarm clock, and the end of the string 35 could be connected with the alarm hammer thereof (and the bell removed or not as preferred), and at the proper hour and minute when the alarm was'released the cord 35 would be drawn on and the trigger T would be operated.

The match clampC consists of a block preferably with a roughened lower face 61, and a plate 62 preferably with a roughened upper face 63-a' screw being passed through the plate into the block, or a screw 64 being fast in the block, passing through a hole 65 in the plate, and receiving a thumb nut 66 on its lower end as shown in Fig. 2. At each side of the block is attached thereto a guide 67 having a horizontal groove 68 standing above the upper face of the block and opposite the slot 2 in the stove door 1. This clamp can be secured to the stove in any suitable.

manner.

In Fig.2 I have shown a screw 70 as passing through the stove door into the guide 67, and'in Fig. 5 I have shown hooks having T- shaped heads 71 adapted to be passed upward through the grate bars and then turned across the same, their bodies passing loosely through lateral slots 72 in ears 7 2' on the guides so they may be adjusted transversely to grate bars differently spaced, and their lower ends 73 being threaded to receive thumb nuts 74.

I do not limit myself to any precise means for connecting the match clamp with the stove, but'the two-means above described are probably the best. By the first, my device can be attached to any stove door by simply cutting the slot 2 therein and boring a hole therethrough for the screw 70; by a second, even the boring of this hole is unnecessary (though the slot must always be cut when the damper opening cannot be used) and the operator can reach in under the grate, pass the hooks up over certain bars, and tighten the thumb nuts to hold the clamp in place. The matches 75 are clamped between the roughened faces 61 and 63 of the block and plate, and these faces stand at an angle with the upper horizontal face of the block so that the matches are presented in an oblique direction to the match-scraper. The latter consists of a plain strip as of wood or metal and to which the wire 17.. is connected. The strip is of a proper width to permit its smooth edges 81 to slide in the grooves 68 in the two guides, and between such edges the faces of the strip are roughened as at 82 in any suit-.

able manner, as by cutting corrugations in the strip or applying sand paper or sand directly thereto. The grooves 68 are so arranged with reference to the clamp thatwhen the matches are held therein as shown, the scraper will pass freely over the block 60 and its roughened lower face will drag over the heads of the matches to ignite them. Thereafter they will burn and their flames will pass upward between the grate bars directly to the fuel which is, of course, already laid in the stove.

With the aboveconstruction of parts, the operation of my device is as follows: The base 13 is placed in front of the stove S and the post P adjusted so that the hole 18 will standabout opposite the slot 2 in the stove door. The clamp is connected with the stove and the fire is built in the latter but not lighted, one or more matches being put into the clamp as shown. The spring arm 15 is then brought up under tension and engaged behind the trigger, and the scraperR is passed through the slot in the stove door and pushed carefully to the rear in the guides. The base 13 is then moved away from the stove until the wire 17 is tight; and the cord 35 is also drawn rather tight and connected with the weight VVthe latter being raised and its wheel 55 resting on the rim 42 of the wheel of the actuatingmechanism; or this cord 35 can be connected with the alarm hammer of an ordinary alarm clock, or in any suitable mannerwith anyother proper actuating mechanism adapted to give the cord a slight pull at the proper moment. When such moment arrives and the cord is pulled (as by the dropping of the weight \/V or the movement of the alarm hammer), the trip 30 of the trigger is moved to release the arm 20, and the spring 15 being released at its upper end drags on principles of my invention.
