PENNSYLVANIA, ASSIGNOR TO GRISWOLD MANUFAC- TUBING COMPANY, OF ERIE, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
i STOVE-DAMPER.
ATo all @07mm it may concern:
Be it known that I, CHARLES A. MASSING, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and use" t'ul Improvements in Stove-Dampers, of
which the following is a specification.
This'invention relates to stove dampers and consists in certain improvements in the construction thereof as will be hereinafterr fully described and pointed out in the claim.
l The invention is illustrated in the aecompanying drawings as follows Figure 1 shows a plan view of the damper. Fig. 2 a section on t-he line 2-2 in Fig. 1.
l marks the damper plate. This has a rod opening 2 formed in it by a series of loops 3. These alternate on different sides of the plate so as to facilitate the casting of the plate. Loops 4: are arranged at the edges of the damper plate. A rod 5 extends through the opening 2.
It will be understood thatthe damper plate is placed in a pipe, holes are madein the pipe by the sharpened end of-the rod 6 or by other means and the rod is passed through the opening 2 in the plate after the plate is in the pipe.V
The rod is provided with'a handle (3 and has a defiected portion 7. Openings-8 are formed in the plate 1 within the loops 4:. In et'ect this opening 8 .is an enlargement of the opening 2. This enlargement is ot' sufficient size to permit of the introduction ot the rod as indicated in dotted lines in Fig. 2 and the turning of the rod in the enlargement so as .to` bring the deflected porthe plate as the loop 4. A slot or seat 9 'is formed in the loop 4 so that as the rod is drawn outwardly toward the edge of the plate the deflected portion is drawn into this seat so as to lock the rod against turning in the opening 2.
A thimble l0 is placed around the rod at its outer end and has a shoulder 11 on the y edge of the plate, the shoulder being formed at the outer edge oi the loop 4. A spring 12 is arranged in the thimble 10 and is tensioned against a shoulder 13 on the rod 5.
In putting the damper in place7 the dami per plate is'put in the pipe, the rod 5 passed through the openings in the pipe and Specification of Letters Patent.

through the opening 2 in the damper plate. The thimble 10 contacts the side of the pipe. The rodis pressed inwardly depressing the spring 12, into position to bring the de fieoted portion 7 to the position shown in dotted lilies in Fig. 2. The rod is then turned bringing the deflected 4portion opposite the seat 9 and as the rod is released the spring l2 moves the rod into the seat and holds it in the seat so that the rod remains locked with the damper plate.
By forming the loops 4 at both edges of the plate and arranging the opening 2 with its enlargement 8 so that the rod may be introduced from eit Ver side of the damper plate, the difficulty which may be experienced from introducing the rod from the wrong side of the damper plate is entirely obviated. This is of particular advantage because the damper plate is ordinarily within the pipe so that it cannot be readily observed- With this device it is immaterial which edge of the damper plate is broughtnext the opening through which the rod is initially passed. All that vis necessary is to bring the damper plate to such position that the rod will enter the opening 2 and where this is done the proper engagement of the rod with the plate is ei'eoted regaidless of the position of the plate otherwise.
"What I claim as new is In a stove damper. thecombination of a damper plate. having a damper opening formed with loops said plate having an enlargement of the rod opening within each loop; a damper rod adapted to enter the rod opening from either side and having a shoulder adapt ed to turn in one or the other enlargement which may loe next the end through which the rod enters and to lock with the plate with an outward movement of the rod after it is turned into the enlargement; and a spring exerting pressure on thel rod to hold the shoulder inloeked position.
at each edge of the plate,
In testimony whereof I have hereunto set
