FLU E-THIMBLE.

SPECIFICATION forming part 0f Letters Patent No. 503,818, dated August 22, 1893.

Application filed February 27, 1893. Serial No. 463.868. (No model.)

To a/Z'Z whom 'it may concern:

Be it known that I, JAMES Il. WATT, of Barnesville, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Flue-Thimbles; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

This invention is an improved ue thimble for use in buildings, where it is desired to convey stove-pipes, or hot air pipes, through the oors, and it is an improvement upon the iiue thimble for which I made application for Letters Patent, Serial No. 454,707, dated December 10, 1892.

The object of this invention is to provide means for adjusting the thimble to a greater variety of thicknesses of joists, or of Iioorings, and to cheapen the construction of my aforesaid thimble, and at the same time improve it, and provide for a thorough circulation of air around the central collar thereby very materially lessening the danger of accidentalV fires; and the present invention consists essentially in the novel construction of the adj ustable two part cylinder or sleeve which surrounds the collar, and in the combination thereof with other parts, as will be hereinafter clearly described and claimed.

In the drawings:-Figure 1 represents a central vertical sectional view through the thirnble as applied to a flooring, and as a iiue base. Fig. 2 is a bottom plan View thereof, and Fig. 3 is a side view of the same, the cylinder being adjusted to suit a thicker joist or flooring. Figs. et and 5 are details.

Referring to the drawings by letters and figguresz-A represents the top plate, having a central opening, for the passage of the smokepipe (not shown) surrounding which opening is a depending collar ct, that should be as long as the thickest j oist or oorin g with which the thimble can be used.

B designates the bottom plate, preferably annular, and fitting loosely on the collar a, as indicated in the drawings. This plate is adj ustaloly secured to plate A by means of through-bolts C, and nuts c, as indicated in the drawings or in other suitable manner, so

that when plate A is supported upon adjoin-n 'any sheet metal, as tin, or cast, or otherwise produced, as desired. Part d has a set of equidistant pins or studs d', attached to it, near its lower edge and projecting radially as shown, by which it is supported on the part D. The upper edge of part D,hasastepped series of

vertical slots

1, 2, 3, 4, 5, eine., in it, each successively deeper or longer than the preceding, there being a set ot such slots for and co-incident with each pin d. As shown in Fig. 1 pins d are in notches 3, and the cylinder is partly extended; by lifting cylinder d and turning it so as to bring pins d over deeper notches, the cylinder can be shortened, and by turning part d, so as to bring the pins over shallow notches, the cylinder can be shortened. By this means the length of the cylinder can be readily and quickly adjusted to suit the varying widths of joists, on which the thimble is suspended, or varying thicknesses of partitions, floorings, &c.

The cylinder sections may be perforated as indicated at d3, if desired, so that air can circulate freely between the cylinder and collar, and thus keepdown the temperature of both. I also propose to perforate the bottom plate B, as indicated at b3, and if desired the top plate, as indicated at a3, so that air can circulate upwardly between the collar and cylinder, as well as laterally around the same.

Instead of the successive series of slots, a stepped-slot, `as indicated in Fig. 4;, or a notched-slot as indicated in Fig. 5, may be used, which will allow ready adjustment of the length of the cylinder, and Will Aalso lock the parts of the same against rotary movements in relation to each other, the essential feature of my present invention being a telescoping two part cylinder, the sections of which can be immediately adjusted, to the desired length, and locked when adjusted; said cylinder-being confined in -position 'between the top and bottom plates.. The series of slots provide for lateralventilation however.`

ing advantages over the thimble shown in my application aforesaid, as in that case the cylinder when the plates are farthestaparQ-'stands'j conslderably above the bottom plate; whereas in the present form, the cylinder alwayscan lay directly on the bottom; plate, and is morefvr u over adapted to a much greater variety of thlcknesses of florings,'&c. lAgain castingV or securing the stepped lugs on the bottom plate, as in my'ii'rstapplication,increased the expenseof manufacture, and the weight of:

the-parts, fsuch lugs being dispensed with` in the; present case.

USmalllugs b2 maybe cast on the fbottom plate, 1 if' desired to' center the cylinder.

Having thus described my.invention,"what I claim asnew, and desire to secure by-Letters `Patent thereon, is-
