UNITED STATES GEORGE M. HAY, OF JOHNSTOWN, PENNSYLVANIA.

IMPROVED ADJUSTABLE COLLAR FOR. STOVE-PIPES.

Specification forming part of Letters Patent No. 414,09 2, dated September 6, 1864.

To all whom it may concern Be it known that I, GEORGE M. HAY, of Johnstown, in the county of Gambria and State of Pennsylvania, have invented a new and Improved Adjustable Chimney-Collar, and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a plan or top view of my improved chimney-collar. Fig. 2 is a horizontal section in the line x x, Figs. 3 and 4. Fig. 3 is an end view, with one of the doors hereinafter referred to thrown open to expose the interior construction of the device. Fig. 4t is a view which exhibits more clearly the sectional collars hereinafter described, a portion of the device being detached.

Similar letters of reference indicate corresponding parts in the several iigures.

This invention relates to a device which is locat( d within a chimney or liuc, and employed to support or retain in position the pipe leading from the stove or other heating medium, and its peculiar construction adapts it for effectual use in connection with a stove-pipe of any dimensions, as will be hereinafter fully explained.

In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, l will proceed to describe its construction and operation.

In the accompanying drawings, A represents a hollow cylinder or collar, through which the stove-pipe passes, which collar may be built or inserted into the wall of the lue. To one end of the cylinder A is affixed what may be termed a circular box,7 which consists of plates B B', and an intermediate connecting-section, B2, the plate B being attached directly to the cylinder. It may be here remarked that the cylinder A is to be large enough to encircle a stove-pipe of the largest size, and that my .invention provides means for enlarging or diminishing the entrance or mouth ofthe cylinder, and thus furnish a supportingcollar for pipes of various sizes. The pla-tes B Bl and the section B2 may be connected together by screws, or in any other desirable manner. IVithin the plates B B are formed openings corresponding in size with the interior of the cylinder A. 0n the outer face of the plate B are secured pieces C C, at the inner edges of which are formed grooves in which work the ends of slides D D, these slides being provided at their proximate edges with folding doors D D', which may be opened to permit the passage of a pipe, or closed when the pipe may be removed from the tlue. The relative situations of the slides D D may be varied so that they will conform to the size ofthe pipe which may pass through the cylinder A and plates B B.

In the present illustration of my invention the drawings represent four pivoted sectional collars between the plates B B. These collars are each formed in two parts, a a, a a', a2 a2, as ai, which are ranged in contact with one another and pivoted at one end of each section upon pivots a4 a4, which are inserted into the plates B B, and through a piece, b, attached to the plate B. The loose ends of the sections are provided with projections or knobs a5, which, by entering slots c c in aslide, E, serve to retain the said ends ofthe sections ot the respective collars in contact with each other, as will be better understood by reference to Fig. 3. Suitable ways for the slide E to move in are formed by pieces F F, in conjunction with the plate B. A

It' the collar a d be not sufticiently large to receive a pipe which it is desired to employ, the slide E may, byineans of aknob, e, (similar to those on the collars a a, &c.,) be slid back so as to permit the sections a a to be turned aside in order to completely expose the collar a a', and if this collar be too small the slide E may be moved back far enough to permit the collar a a to be turned aside to expose the collar a2 a2. In this manner it is manifest that the entrance of the cylinder A may, with facility and expedition, be made larger or smaller, as required. When the sections a a, &c., are turned aside to expose those which may be behind them, they occupy positions between the plates B and B', the knobs a5 enten ing slots bin the plate B. The slide E moves upon and is supported by a guide, e2, to receive which the slide is provided with a way, e3. Then it is desired to turn aside the entire series of collars, so as to adapt the device for a collar sl fticently large to tit snugly within the cylinder A, the knob e of the slide enters a small recess, b', in the plate B.

l do not confine myself. to the number of sectional collars herein represented, but propose to employ :1s many as may be eompaetly' plnced Within the box B B B2.

Having thus described my invention, the'7 following is what Icla-im as new therein sind desire to secure by Letters Patent:

1. A chimney-collar in which a series of pivoted or sliding seinicircular sections, (t a, &c., are employed to adapt the collar for pipes ot' various dimensions, substantizillyas herein set forth.

2. The combination of the plates B Bf, intermediate section, B2, cylinder A, and slide E, the whole being` constructed and arranged to operate in the manner specified.

3. The slides D D, folding doors D D', and pieces G C, for adapt-ing the opening in the cylinder A to be closed when the pipe is not in use, substantially as specied.

The above specification of my improved ad justable collarfor stove-pipes signed this 16th day of May, 1864.

GEO. M. HAY.
