SPECIFICATION forming part of Letters Patent No. 772,251, dated October 11, 1904.

Application filed October 22, 1903. Serial No. 178,118. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN H. NICHOLS, acitizen of the United States, residing at Anamosa,

in the county of Jones and State of Iowa, haveA invented certain new and useful Improvements in Flue-Stops, of which the following is a speciication.

This invention relates to improvements in that type of fine-stopping devices consisting of a head or face-plate of ordinary form and a scoop device carried by the head to receive the dirt or soot which would otherwise fall.

. edge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

W'hile the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in whichi Figure 1 is a perspective view of the stop, showingthe adjacent parts attached thereto. Fig. 2 is a vertical sectional view showing the stop in position. Fig. 3 .is a detail perspective View of the scoop-plate and spring, a fragment of the face-plate being shown.

4Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The device comprises four essential partsnamely, a support or thimble 7, a head 0r face-plate 1, a scoop-plate 2, and a spring 3, letachably secured to the scoop-plate and iea and is provided with openings 4, which receive lugs 5, projected from the scoop-plate 2, the

van approximately vertical position.

The head is stamped from sheet metal saidlugs being bent angularly to secure the scoop-plate to the head, as shown. The spring 3 is of approximately circular form, one of the ends ofthe spring being bent to form a hook 6, which passes through openings in the scoop-plate 2, detachably securing the said end to the plate. The opposite end of the spring 2 passes through openings in the faceplate or head l, and any suitable means may be provided to prevent displacement of the ends of the spring from the plate 1 and the scoop-plate 2. The extremities of the spring are preferably bent, so as to prevent the accidental displacement above mentioned. The spring, as readily seen, extends laterally from the rear side of the head l and is disposed in The curved portion of the spring when in frictional contact with the thimble 7 of the stovepipe serves to substantially hold the fine-stop in position, at the same time permitting of rei moval of the said stop when desired.

It is designed, of course, to provide ornamental finishing upon the head l, as is usually done.

Having thus described the invention, what is claimed as new isy In a flue-stop, the combination with a supportprovided with an opening, of a head-plate provided with openings adjacent the upper portion thereof, a scoop-plate having lugs extended from the upper side portions thereof and received by the aforesaid openings in the head-plate, said lugs being bent to secure the scoop-plate to the head-plate, a spring of approximately circular form projected rearwardly from and at about right angle to the head-plate, said spring being adapted to be received in the opening of the support to bear against the walls thereof and having its upper end secured to the head-plate and its lower end bent to form a hook-shaped terminal, the hook-shaped terminal of the spring being secured to the lower portion of the scoop.

In testimony whereof Iaifix my signature in presence of two witnesses.
