1 Claim.

l This invention relates to a damper, and more particularly to such a damper adapted to be utilized in flues or chimneys, or the like.

A primary object of this invention is the provision of an improved damper adapted to be positioned in the flue or chimney of a replace, furnace, or the like, characterized by means whereby the same may be adjusted to t any desired size of flue or chimney.

An additional important object of this invention is the provision of such a damper which may be readily applied to existing chimneys or ues.

Still another object is the provision of such a damper having improved control means thereon adapted to extend exteriorly of the ue or chimney, whereby the position of the damper may be readily controlled.

Additional objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter, and disclosed in the accompanying drawings, wherein there is shown a preferred embodiment Iof this inventive concept.

In the drawings:

Figure 1 is a top plan view of one form of damper embodying features of this invention.

Figure 2 is a bottom plan view of the device shown in Figure 1.

Figure 3 is an end elevation view of the device shown in Figures 1 and 2.

Figure 4 is a side elevational view of the device.

Figure 5 is an enlarged fragmentary view of `a constructional detail, and

Figure 6 is an enlarged fragmentary perspective view of an additional constructional detail.

Like reference numerals refer to like parts throughout the several views of the drawings.

Having reference now to the drawings, the damper is comprised of two members, one generally indicated at IIJ comprising a fixed portion, and the other generally indicated at `II comprising a movable portion. Referring, first, to portion I0, it will be seen that the same is comprised of two plates I2 and I3, the edges of each being rolled, as at I4 and I5, the rolled edge I4 being adapted to t slidably within the roll I5. The plates I2 and I3 are bent at right angles, as at I5 and I'I, respectively, to form a right angled flange, extending upwardly with respect to the plate portions. Adjacent the extremities of the portion III, lugs I8 and I 9 are struck from the material of the plates I2 and I3, respectively, and provided with apertures therein (see Fig. 5) adapted to engage the extremities 20 and 2|,

respectively, of roll portions 22 and 23, similar to roll portions I4 and I5, formed on one edge of damper member II, which, it is noted, is comprised of two plate- like members 24 and 25. Similar rolls 26 and 2'I edges of the plate- like members 24 and 25, the rolls 23 and 21 adapted to be slidably positioned within rolls 22 and 26, whereby the plates may be slidably moved with respect to each other.

Spaced lugs 30 are adapted to be struck from an intermediate portion of plate I2 and depend downwardly therefrom, and additional spaced lugs 3| are adapted to be struck from an intermediate portion of the plate 24, and similarly depend therefrom. A lever 32 is adapted to extend between lugs 30, being pivotally secured thereto, as by a bolt 33 and nut 34, and is secured at one extremity to a link 35, as by a nut 36 and bolt 31. The opposite end of link 35 is secured, as by a nut 38 and bolt 39, between lugs 3| of plate 24.

From the foregoing the method of use and operation of the device should be readily understandable. The damper is first adjusted to the size of the ue in which it is desired to be utilized, by moving the plates 25 and I3 inwardly or outwardly with respect to their associated plates I2 and 24, respectively, the roll members I5, 23 and 2'! being respectively slidable within the correspending members I4, 22 and 26, and the device is then positioned within the chimney, plate member I Il being xedly secured in any desired position in any desired manner therein. The extremity of the lever 32 extends outwardly from the ue or downwardly with respect thereto, in order to be readily accessible, and, it will be seen that movement of the lever 32 varies the position of plate member I I, which serves as a damper member within the flue.

From the foregoing it will be seen that there is herein provided a device accomplishing al1 the objects of this invention and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

In a damper assembly, the combination of two elongated base members of L-shape in cross section longitudinally and slidably secured in nested contact with each other with the outer surfaces are formed on the opposite of the legs of one member in face to face contact with the inner surfaces of the corresponding legs of the other member, whereby the two members are capable of longitudinal sliding movement relative to each other for fitting the damper in a ue, a pair of fiat members extending longitudinally of said base members, the lsame being in face to face vcontact and movable with respcii to each other longitudinally of the base members, such movement corresponding to the relative movement of the base members with respect to each other, one edge of said members bei-ng disposed adjacent the outer ilat kside of Vone of the legs of said L-shaped base members and pivotally mounted upon said flat side .of said base members on an axis extending longitudinally thereof, a pair of lugs struek'f-rom one lof said base members and a corresponding pair `of lugs struck from one of saidjlat members, the lugs of each pair beine in alignment with-each .other with those of the other Pair, a damper op @rating lever pvotally .Connected intermediate its ends betweenthe lugs op `said'ilone of said base members, and a connecting 1.11115 .pivotally conpsted at .one end between the lugs onsaid one of said flat members and pivot-,ally connected at its opposite end to the adjacent end of said damper operating lever.
