FLU E-STO P.
SIPEGIFICATION' forming part of Letters Patent No. 620,129, dated February 28, 1899.
Application filed June 8,1898. Serial No. 682,964. (No model.)
is a clear, full, and exact description of thesame.
The invention relates to improvements in flue-stops.
The object of the present invention is to improve the construction of flue-stops and to provide a simple, strong, and durable one adapted to be readily constructed of sheet metal and wire and capable of having its parts quickly assembled and adjusted to fit a flue.
The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.
In the drawings, Figure l is a sectional view showing a flue-stop constructed in accordance with this invention and shown applied to a flue. Fig. 2 is a front elevation of the flue-stop. Fig. 3 is a detail view of one of the resilient hooks or rings, showing-the opening for engaging the worm or screw.
Like letters of reference designate corresponding parts in all the figures of the drawings.
A designates a concavo-convex circular cap adapted to cover a flue, as illustrated in Fig.
1 of the accompanying drawings, and provided at its periphery with a fiat portion or flange to fit against the wall or surface surrounding the flue, and it is provided with a central concavo-convex depression A extending inward and forming an outer recess. The depressed central portion of the cap A is provided with a central hole or perforation, through which passes a rod B, provided at its outer end with a head or handle I) and having a screw or worm 5, preferably formed by twisting a pair of wires, as shown. This rod,
which is journaled on the cap, is adapted to be rotated to manipulate a pair of resilient hoops or rings 0 and 0, arranged at right angles to each other and provided at their rear point of crossing with openings a, receiving the rear end of the rod and engaging the worm similar to a nut, whereby when the rod is rotated the rear portions of the hoops or rings will be moved inward or outward to engage them With and disengage them from the walls of the flue-opening, as will be readily understood. The hoop or band 0, which is arranged outside of the other hoop or ring, is provided with an outward depression or bend f, forming a seat to receive the hoop or band 0. The terminals of the hoops or rings are overlapped and connected by the rod B,which passes through registering perforations of the overlapped ends of the metal. The ends of the inner hoop or ring 0 are arranged on the inner face of the cap A at the central depressed portion thereof, and the terminals of the outer ring or band extend through opposite slots A of the cap and are aranged on the exterior of the same beneath the head 12. One of the terminals of each hoop or ring is bent or offset to provide a recess to receive the other, as clearly illustrated in Fig. 1 of the accompanying drawings.
The invention has the following advantages: The device, which is simple and comparatively inexpensive, may be readily constructed of sheet metal and wire, and it is strong and durable and adapted to be readily applied to a line. The hoops or rings, which are constructed of strips of sheet metal, have their overlapping ends secured to the inner and outer faces of the cap by the rod, which is provided with the worm. The rod is adapted to be readily rotated to expand and contract the hoops or rings, which are arranged at right angles to each other.
Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit and scope or sacrificing any of the advantages of the in vention.
What is claimed is- 1. A device of the class described compris ing a cap provided with opposite slots, the hoops or rings arranged at right angles to each other and consisting of strips of metal having overlapped ends arranged on the inner and outer faces of the cap, the ends of one of the hoops or rings being passed through the said slots, and a rod extending through the cap and the hoops or rings, and securing the overlapped terminals of the latter to the cap, and
having a worm or screw engaging the hoops or rings at the back thereof, substantially as described.
2. A device of the class described comprising a concavo-convex cap having a central depressed portion A provided with opposite slots, the hoops or rings arranged at right angles to each other and constructed of strips of metal having overlapped ends arranged on the inner and outer faces of the depressed portion of the cap and provided at their points of
