SPECIFICATION forming part of Letters Patent No. 249,103, dated November 1, 1881.

Application filed September 12, 1881.

To all whom it may concern:

Be it known that I, THEODORE SOHAFER, of Maroa, in the county of Macon and State of Illinois, have invented certain new and usefulImprovementsiu Stove-PipeThimbles; and I do hereby declare the following to be a full, clear, and exact description of the im'ention, such as will enable others skilled in the art to which it pertains to make and use it, referen ce being bad to the accompanyingdrawiugs, which form part of this specification.

My invention relates to an improvement in stove-pipe thimbles; and it consists in attaching springs or other suitable holding devices to the inside of that section of the pipe which passes through the wall, and forming in or attaching a screw-thread to this section a suitabledistanceinward from the end which passes through the wall, and passing a screw-collar 'over the section and screwing it up against the wall on the inside of the room after the springs have been made to catch against the inside of the wall, and thus forming, by the help of a suitable packing, a tightjoint against the wall, so as to prevent smoke and soot from getting into the room.

The object of my invention is to provide a safe and easy method of fastening the stovepipe to the wall, and in such a manner that no smoke, dust, or soot can escape into the room.

Figure l is a perspective of my invention. Fig. 2 is a section of the same.

A represents that section of the pipe which is intended to pass through the wall B, and which has secured to opposite inner sides the spring-catches 0. These catches are to be pressed inward by hand or other means while the end of the pipe is being inserted through the wall, and as soon as they are released catch against the inner side of the wall, and prevent the section from being easily drawn outward. Upon the outer surface of this section A is either attached to or formed in the pipe itself a screw-thread, D, with which the corresponding thread of the collar G is made to engage. This collar G is passed over the outer end of the section A, and after the springcatches have caught against the inside of the wall is screwed up against the outer side of the wall, as shown. Between the edges of this collar and the outer side of the wall is placed (No model.)

a suitable packing, I, which, after the collar has been screwed up, forms a tight joint to prevent dust, soot, and smoke from being blown into the room. This collar and the springcatches hold the section A very rigidly in place, and make a very secure and perfect fastening, and one which any one can readily apply. In case the section A is made of elastic metal, the springs may be outta the pipe itself and have the ends turned outward, so as to catch inside of the wall in the same manner that the spring-catches do. 4

The fastening above described is equally well adapted for being used up against the ceiling as against the side of the wall.

The section A is to be united to the next section by means of a bayonet-joint, as shown, and the button or catch R, which is formed on the adjoining section P, instead of being made solid, will have an eye made through it, as shown, into which the bent arm S can be inserted, and upon this arm can be hung towels or other such articles to dry. This arm, being attached directly to the stove-pipe, will give articles that are being dried the benefit of the heat from the pipe without the slightest danger of burning them.

I am aware that the end of the pipe has been passed through the wall into the chimney,

and then prevented from bein g withdrawn by suitable devices which catch against the inside of the wall, while a tight joint is made with the outer side of the wall and the pipe by suitablepackings; and this Idisclaim. My invention differs from this in the use of springs and the use of a screw-collar which can be readily and quickly tightened in place.

Having thus described my invention, I claim- The combination of the section A, provided with spring-catches (J upon its inner sides to catch against the inside of the wall, and havin g a screw-thread upon its outer surface,with a screw-collar and a packin g-rin g, substantially as shown.

In testimony whereofI aifix my signature in presence of two witnesses.
