Serial No. 44,422.' I I Be it known thatI; SAMUEL Haddonfield, ,county of Camden, State of New Jersey, h'ave invented a new anduseful Automatic. Dust-Damper for Stoves, ot which the following-is aispecification. I y

In a prior application filed by me on July 22nd, 1914, ser1a1 No. 852,3et9, of which this, in its broad aspects, is. a continuation, I have described and broadly claimedanovel construction of a stove wherein the parts that they return to their initial or normally closed position due to the force of gravity.

Other novel featuresof construction and advantage will hereinafter more clearly appearin the detailed description of my invention. V

c For the purpose of illustrating vm y invention .I,have shown in the accompanying herein shown and described K tional view on line 1.

The opposite end of the link 16' is provided with a plurality of spaced apertures 20 through a desired one of which is adapted to pass a fastening device 21 such as, forexample, afeotterpin, said pin also passing through one of the longitudinally spaced apertures 22 of a link 28. The opposite end of said link 23 is provided with a plurality of longitudinally spaced apertures 2% through which is adapted to pass a fastening device, such as for example, a cotterpin 25, which also passes through one of the longitudinally spaced ape rtures'26 at the end'of the extension 27 of a rod 28. The rod 28 passes through one of the apertures 29 in the rear plate of the stove and also through one of the apertures 30 in the front plate of the stove and its outer end is adapted to be connected with an arm 32 in desired manner. In the present instance I have shown this as being accomplished by having the end of the rod 28 in threaded engagement with the; arm 32and fixed in position by means of a pin 33 passing throughsaid arm and rod. The arm 32 terminates in lateral extension 84 which rests upon or in close proximity to outer end of the grate actuating member 85, illus- 36 designates a 7 wei ht or counterbalance having a recess 37 adapted to receive the dowel pin 15 of the damper, 8 and the counterbalance is provided at its outer end with spaced apertures 38' located at opposite sides of the counterweight.

89 designates a fa'steningdevice, such as for. example a bolt and nut, the bolt being adapted to pass through predetermined apertures 10 and 3,8, in order to maintain the counterweight 36 in assembled condition with respect to the damper 8. The rear plated of the stove is provided in proximity to each dust flue 3 and 6 with an opening l0 adapted to receive a dowel pindl carried by a guide l2 which latter is secured to the rear plate at by means of a fastening device passing through one of the apertures tl in the rear plate' l of the stove.

The guide bracket or plate 42 is provided with an ofi-set portion 4:5 thereby forming a shoulder d6, in proximity to which the damper 8 travels and the off-set portion 45 forms a flange to guide the damper. during it movement. 7 v

In some cases the actuating arm 47, seen 1n Fig. 11, may be employed and provided \vlth a deflected rounded portion 48 adapted to fit over the. actuating member of the grate such as, for example, thedrawbar, shaker bar or their equivalents.

The movement of the damper 8 toward its closing position is limited by means of a lug L9 connected with or forming a part of th r a eve 2 Tn the operation of my device, assuming that the parts are constructed as seen in Fig.

28 and through the cooperation of links 2 16 he, d mp wi l be w ms w wardly,

The amount of movement imparted to the damper may readily varied by adjusting the fastening devices 2 5 or 21, it being noted that in the form illustrated, a plurality of ap- 'tures are provided the link 28 with which such fastening devices are adapted to cotiperate so that the length of stroke of the damper 8, may vary accordance with the conditions and requlrements met with in practice. w

It will be apparent from the foregoing that the damper is normally maintained in closed position by means of a counterbalance means a e empl ed ter t e y Q0 nected with the damper and extending in Pr xim y h r te a' ti a ins m m wherebywhen the shaking element or imple ment'is' assembled with respect to, the grate t a in me ber it ll effect t e perat of the latter and cause the damper to open q w eti l by mean ft flue pe in with the ash pit and the exhaust flue leading to the smoke pipe of the stove.

' Attention is directed to; the fact that the Par s of he d mpe m chanism are w structed in such a manner that they can be arranged for either a right or leftehand a e t, of th l -le r I al ov erov means to limit the movement of the damper on its return movement-"sosthat thedamper will be maintained in-closed position at all times except; when it is.desired to shake the grate. A

Attention is.also directed to the manner in which the various parts are constructed in order that the amount'of movement im- 7 parted to the damper maybe. varied as desired.

I have preferred to y the damper mechanism located within and a portion located without the stove, but it will be apparent that the entire damper mechanism may be located either interiorly or exteriorly of the stove and still be within the scope of my invention.

It will further be apparent that, if desired, I may dispense with the counterbalance 36, since the parts connected with the damper may have the desired weight to effect the return of the parts to their normal position or the arm, such as 32 or 47, may be weighted in order to accomplish this purpose, it being seen that in such event, the

parts of the damper are returned to their initial or normal position,

due to force of gravity. The portion of the actuating arm extending in proximity to the grate preferably is of a contour conforming to the contour of the end of the actuating member of the grate.

It will be apparent that my device may be used in connection with any desired type of a grate, in which a member is provided to effect the shaking thereof and the passage 1 of the ashes into the ash pit.

It will now be apparent that I have de' vised a novel and useful construction of an automatic dust damper for stoves which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and While I have, in the present-instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages. 7 Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with the ash pit, thedust flue, and the actuating member of a grate, of a damper controlling said flue, a

counterbalance for said damper, and an arm operatively connected with said damper and in proximity to said member, whereby upon the assembling of a shaker element with said member said damper will be moved to open communication between said ash pit anddust flue.
