STOVE-PIPE THIM BLE.
SPECIFICATION forming part of Letters Patent No. 364,651, dated June 14,1887.
Application filed July 1'7, 1886. Serial No. 108,341. (No model.)
To all whom it may concern:
Be it known that we, SHERMAN G. Huron;
ms, of Chelsea, in the county of Suffolk, State 1 tion appertains to make and use the same, reference being'had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of the stove-'pipe thimble proper; Fig. 2, a front end elevation of the same; Fig. 3, a front elevation of the guard; Fig. 4, a vertical transverse section of the same; Fig. 5, a vertical section showing the thimble and guard united; Fig. 6, a rear elevation of the guard represented as in position to be placed on the thimble, and Fig. 7 a horizontal section showing the thimble and guard in position for use. A
Like lettersofreferenceindicate corresponding parts in the different figures of the draw- 1n s.
In the construction of dwelling-houses and similarbuildings having wooden partitions, it is usual to erect the studding to which the laths are attached at some distance from the brick-work of the chimney, and to build a horizontally-arranged branch flue leading into the same, the outer end of said flue being flush with the'lathing and the funnelthimble in serted therein.
As the branch flue is composed of brick and mortar, and usually supported in a framework of wood which rests on the studding and chimney, itis comparatively expensive to construct and very liable to get out of order, the operation of inserting the stove-pipe in and removing it from the thimbleiu the outer end 7 of the chimney-flue tending to loosen the materials of which it is formed, and consequently tending to endanger the building from fire.
Our invention, which consists in certain details of construction hereinafter set forth, and pointed out in the claims, is designed to ob viate these objections; and to that end we make useof means which will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the thimble proper, B the guard, and O the chimney.
The thimble, which is cylindrical in form, is preferably composed of cast-iron, and is provided near its outer end with an annular flange, w, and at its extreme outer end with an annu;
lar lip or fiange,f, the latter projecting from the body of the thimble about half the distance of the'forrner, and'the two flanges being connected at intervals by lougi-tudinally-arranged ribs d.
The guard B is preferably composed of castiron, and is provided with a series of elongated slots or perforations, m, for receiving and holding the plaster, and with a centrally-disposed hole, E, of proper size to permit the outer end of the thimble to be inserted therein. It is also provided with holes 1', for receiving the nails by which it is Secured to the studs.
Projecting from the rear side of the guard,
near the thimble-hole E, there are two hooks, 7 5
Z, which are adapted to engage the flange a, said flange being provided at opposite sides of the thimble with notches 1, through which said hooks pass when the guard is placed on the thimble.
In the use of our improvement the inner end of the thimble is inserted and properly secured in the chimney 0, its outer end being so arranged as to be flush with the plastering when it is applied, as Shown in Fig. 7. guard B is then arranged vertically, as shown in Fig. 6, and passed on over the outer end of the thimble until it strikes the flange at, its hooksl passing through the notches t, after The which it/is turned until brought into a hori- 9o through the holes t and the plastering II applied to the guard and lathing .2.
It will be obvious that the guard B serves to firmly support the outer end of the thinlble, and also subserves the purpose of metallie lathingin the vicinity ofthe thimble, there- K 0 by preventing the surrounding woodwork from becoming overheated or taking fire from the stove-pipe.
Any suitable stopper or cover may be employed to close the outer end of the thimble when it is not in use or when a stove-pipe is not inserted therein.
The ribs (1 serve to center the guard B and support it in proper position on the thimble after it has passed over the outer flange, The flange or lipf serves to hold the plaster, which as it is applied to the guard is pressed into the pockets 1), formed between the flanges x and f and bars (1. By looking the guard to the thimble these parts are pre vented from being separated by the springing or shrinkage of the woodwork or settling of the chimney, although the guard will usually keep its place without being looked to the thimble.
It will also be obvious that instead of the flange .r extending entirely around the thim ble, one or more shorter flanges or projections adapted to engage the hooks Z may be em ployed, ifpreterred.
The hole E in the guard is suflieiently large to permit the outer end of the thimble to be readily inserted, but not large enough to pen mit the flange a; to pass through it.
Instead of the hooks Z and flange a", any other suitable means may be employed for locking the thimble and guard together.
XVe do not confine ourselves to the use of the ribs (1, as they may be omitted, if desired. Neither do we confine ourselves to the use of the flangef; nor to providing the body ofthe guard with the elongated slots m, as instead of said slots any other suitable openings for receiving the plaster may be employed; nor to locking the guard to the thimble; nor to extending the flange x entirely around the thimble; nor to the use of the hooks Z.
It will be understood that the thimble A may be made of any desired length and diameter, in accordance with the distance of the studding from the chimney and the size of the stovepipe to be used in connection therewith; also, that the guard may be of any desired size or shape, the rectangular form shown being deemed preferable.
Having thus explained our invention, what we claim is- 1. A stove-pipe-thimble guard consisting of a flat metallic plate having a central opening for thcst'ove-pipe, said platebeing solid around.
said opening and provided with perforations between its solid portion and its outer margin for receiving plastering, substantially as described.
2. A stovc-pipe-thimble guard consisting of a flat metallic plate having a central opening for the stove-pipe, said plate being solid around said opening and provided with perforations between its solid portion and its outer margin, and with nail-holes for receiving the fastening-nails, substantially as described.
3. A stove-pipe-thimb1e guard consisting of a flat metallic plate having a central opening, said plate comprising a solid annular inner rim surrounding said opening and a solid outer rim at the margin of the plate, said plate being perforated between its inner and outer rims for receiving plastering, substantially as described.
4:. A stove-pipc-thimblc guard consisting of a flat metallic plate having a central opening for a stovepipe, said plate comprising a solid inner rim surrounding said opening and a solid outer rim at the margin of the plate, said plate being perforated between its inner and outer rim, andsaid inner rim being provided with hooked lugs for connection with the stove-pipe thimble, substantially as described.
53. A stove-pipe thimble provided with a peripheral flange near its outer end and with a narrower flange at its outer end, the space between said flanges being adapted for bolding plastering, in combination with a stovepipe-thimble guard provided with a locking device for engaging the wider flange of said thimble, substantially as described.
6. A stove-pipe thimbleprovided with a flange near itsoutcr end and with longitudinal ribs extending outward from said flange, in combination with a stove-pipethimble guard locked to said flange and centered by said ribs, substantially as described.
7. The thimble A, having the flange as, provided with the notches i, in combination with the guard B, having the hole E, hooks Z, and slots at, substantially as set forth.
8. The thimble A, having the flanges m f and bars (I, in combination with the guard 13, having the hooks Z, slots at, and hole E, the flange a" being provided with notches 1, substantially as described.
