JACOB STEINHILPER, OF DUBOISTOVN, PENNSYLVANIA.

STOVEPIPE-COLLAR.

SPECIFICATION forming part of Letters Patent No. 697,034, dated April 8, 1902. v

Application filed October 29, 1901. Serial No. 80,447. (No model.) a

To (all whom it 771/1711] concern.-

Be it known that I, JACOB STEINHILPER, a citizen of the United States, residing at Duboistown, in the county of Lycoming and State of Pennsylvania, have invented a certain new and useful Stovepipe-Oollar,of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to stovepipe-collars, the object in view being to provide at a minimum expense a reliable and efficient thimble or collar equipped with means for retaining itself securely in place at the front of a chimney-flue and at the same time securely holding the adjacent end of a stovepipe or section thereof, as well as a fine stopper or cap when the stove is notin use and the stovepipe is unmounted.

The chief aim of the present invention is to provide in connection with a Stovepipe-collar a single spring device which acts at one and the same time to retain the collar in place and frictionally hold and grasp the stove- \Vith the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a horizontal section through a portion of a chimney, showing the chimney-flue, the opening leading thereto, a portion of a stovepipesection, and the collar forming the subjectmatter of this invention. Fig. 2 is a perspective View of the collar looking toward the inner side thereof. Fig. 3 is adetail perspective View of one of the elbows of the retaining device, showing a modification in the formation of the engaging point thereof. Fig. at is a horizontal section showing a flue stopper or cap fitted into the collar and held thereby.

Similar numerals of reference designate corresponding parts in all figures of the drawings.

Referring to the drawings, 1 designates a portion of a chimney, and 2 the aperture or hole leading to the flue, while 3 indicates the adjacent end of a stovepipe or one of the sections thereof which it is desired to hold in place in proper relation to the chimney-flue.

In carrying out the present invention I employ the ordinary collar 4., which maybe flat or concavo-convex in cross-section and which may be either plain or ornamented to any desired extent. This collar has applied to its inner surface a retaining device consisting of a spring 5, the main body or central portion of which is bent in the form of a bow and secured throughout a portion of its length to the inner surface of the collar, a sufficient portion of the bow being, however, left free in order to provide for the necessary yielding or springing of the end portions of the retaining device. I

By reference to Fig. 2 it will be seen that the bowed portion of the spring is connected with the collar between the points 6 and 7, while from said points outward to the extremities of the spring the latter is left free to operate in the mannerhereinafter set forth. The bow-spring is described on the arc of a circle of less diameter than that of the opening in the collar and is attached to the collar at a point removed from the inner edge thereof, as clearly shown in Fig. 2. As a result of this arrangement the end portions of the bowed portion of the spring project within the inner edge of the collar in order to bind against the stovepipe 3 in the manner illustrated in Fig. l and to bear the same relation to the flue stopper or cap 8 as illustrated in Fig. 4.

At the point 9 the spring wire or rod of which the retaining device is formed is bent abruptly to form rearwardly or inwardly di-' verging or flaring arms 10, the said arms being adapted to project into the flue-hole, as shown in Fig. 1, and to bear at diametrically opposite points against the inner surface of said hole with a pressure sufficient to eifectively hold the collar in position. The pressure of the arms 10 against the inner surface of the flue-hole also has the tendency to press the elbows 9 inward with greater force, thereby causing them to impinge with considerable pressure against the stovepipe when the latter is thrust through the opening in the collar.

In Figs. 1, 2, and at the elbows 9 are shown as formed by simply bending the spring wire or rod abruptly, while in Fig. 3 the elbow is flattened, as shown at 11, either by mashing the same under a hammer or filing the opposite surfaces of the elbow, the resultbeing thata biting edge or angle is formed at the point of the elbow, such edge being disposed inwardly, so that it has a tendency to indent the stovepipe, and thereby obtain a firmer and more positive hold upon said pipe.

When the stovepipe is not in use and after it has been removed from the collar, the stopper 8, which is provided with the inwardlyextending annular flange 12, is inserted into the collar in the manner shown in Fig. 4E and is held by the pressure of the clamping-elbows 9 in the same manner as the stovepipe.

From the foregoing description it will be seen that the retaining device, which is applied to the rear surface of the collar, performs the dual function of properly positioning and holding the collar in place and also binding and clamping the Stovepipe or fluestopper,.as the case may be, within the collar. The said retaining device is constructed inexpensively from a single piece of spring wire or rod and may be secured to the collar by soldering, brazing, or in any convenient manner.

Having thus described the invention, I claim as new 1. The combination with a stovepipe-collar, of a spring retaining device applied to the inner surface of the collar proper, said retaining device being in the form of a spring-strip the end portions of which are bent to provide flaring arms with unconfined extremities which engage the chimneyfine and oppositelylocated and inwardly projecting elbows, which clamp the pipe, substantially as and for the purpose described.

2. The combination with a stovepipe-collar, ot a combined collar-retaining and stovepipeclamping device, the same consisting of a spring-strip the body portion of which is bent in the form of a bow and secured throughout a portion of its length to the collar, the end portions of the strip being left free and bent to form elbows which project within the edge of the opening in the collar for engaging the Stovepipe, and divergent arms adapted to bear against the flue at opposite points for retaining the collar in position.

3. The combinationwithastovepipe-collar, of a combined collar-retaining and stovepipeclamping device consisting of a strip of spring material secured to the inner surface of the collar and having its end portions bent to form spring retaining arms and elbows which project partially within the edge of the opening in the collar, the said elbows being fiattened to form biting edges adapted to impinge against the stovepipe at opposite points.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB STEINIIILPER.
