To all whom t may concern,.-

Beit known that I, WELLINGTON WILSON, of Bay City, in the county of Bay and State of Michigan, have'invented new and useful Improvements in Stovepipe Attachments, of which the following is a full, clear, and exact description.

This invention relates to means for attaching stove pipes to chimneys, also which may serve to hold in place the us'ual'slip collar on the stove pipe that closes the marginal portion of the opening in the chimney wall through which said pipe enters.

The invention consists in a device or attachment of novel construction for such purpose or purposes, substantially as hereinafter described and pointed out in ythe claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters ofk reference indicate corresponding parts in all the figures.

Figure 1 representsa longitudinalsectional elevation of the chimney en'd portionor section of a stove pipe, and sectional view of the chimney, in part, into which said pipe is fitted, together with a longitudinal view of my improved stove pipe attachment applied. Fig. 2 is an upper longitudinal view of said stove pipe piece or section removed from the chimney and with the improved attachment in place on the stove pipe. Fig. 3 is a top viewT of said attachment detached from the pipe; and Fig. fl is a broken plan view of a stove pipe, showing a slight modification in the construction and arrangement of one of the details of the attachment.

A indicates a piece of stove pipe the one end of which is designed to enter a hole in the wall B of the chimney B', and C is the usual slip collar that tits over the pipe A, to close the marginal portion of the hole in the chimney wall through which said pipe enters,

and to give a finish to the stove pipe connec-` tion with the chimney.

D is the stove pipe attachment which holds said pipe to its place in the chimney, and which may also hold the slip collar C in place. This attachment, it is preferred to arrange, for convenience sake, 0n the top of the stove pipe A, but it might be on any other side thereof. It virtually consists of a longitudinal piece of spring wire anchored tothe pipe and constructed to form, by a coil or otherwise, a spring d, at its inner end which may partly lie Within the pipe, and terminates in a spring armor branch d', project-ing upward orlaterally from and outside of the pipe at the'inner end of the latter, to spring out andbear against the inside surface of the chimney Wall B when the pipe is in place. Itis also constructed With a loop or spring coilf, at its outer end terminating in a springarm or branch f', which when the pipe is in place serves to bear against the slip collar C to hold itin place. The loop or spring coilfserves to receive the head or loop end of a spike G, to anchor the attaching device to the stove pipe A. The point of the said spike may either be pressed or projected into the body of the pipe, and bent more or less, as shown in Fig. l, or the point may be inserted between the edges of t-he pipe, at the seam, as shown in Fig. 4. The anchor G is separate from the main wire or part D vand its loop g, embraces the coilf and is free to 'swiugthereom and this connection leaves theanchor no tendency to release itself from the pipe when driven into the same and permits it to be readily disengaged from the pipe (by the insertion of any convenient tool or device), as theanchor will rise bodily instead of being bent from its point of connection which would'offer more resistance.

It will be observed that the spring coils d and f are disposed, at right angles to each other, and that the inner coil d is substantially parallel with the longitudinal axis of the pipe thereby receiving the innerend of the pipe between the coil and the main length of wire D. The coil f with the returned arm f has a spring action from its connection with the said coil f', and the arm thereby is self adjusting to the thickness of the chimney and the extent of this adjustment is limited only by the length of this arm. The end spring or arm d at the inner end of the pipe is pulled over on top or outside of the inner end of the pipe toenter the hole in the chimney wall B which said end of the pipe enters, the small spike or anchor G at the other end of the fastening being driven through the pipe. After this has been done', the slip collar C is passed on and over the pipe and `the pipe with its attachment driven into the wall B of the chimney. This will, as soon IOO as the spring arm d has been driven into the chimney in fitting the pipe to its place, 4cause said spring or arm d to spring outward and assume an upright or lateral position on the inside surface of the chimney wall B, to lock or hold the inner end of the pipe thoroughly fast. During the latter part of the inward movement of the pipe and its attachment, the collar C having contacted with the chimney will be arrested, and as the pipe is forced inward the spring arm f will yield until the inner arm d can spring upward, and thereby the said inner spring arm will engage the inner surface of the wall while the outer spring arm f will press forward against the collar C, so that no vibration will allow the pipe to work out of the chimney or out of place until, when required, the spike or anchor Gr is'lifted out of the pipe, which is necessary to be done to enable the pipe to be drawn out of the chimney. i

With this chimney and stove pipe attachment, as 'shown and described, no specially constructed pipe is necessary and it is adapted to all chimneys. It is not liable to get out of order and its cost is small, both to the trade and public, while its little bulk and weight makes the expense of shipment inconsiderable. It is also so simple in adjustment that even an inexperienced person or child, able to give a light blow on the spike or anchor, will be competent to adjust it and make it firm to the pipe. It also prevents the pipe from being put too far into the chimney.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. As a new article of manufacture, a stove pipe attachment, consistingr of an elongated main member or body having at lits inner end a spring coil and an arm projecting from said coil, the coil serving to receive the inner end of a pipe between itself and the main length or body and serving also to give the spring action to the arm, and a returned spring arm on the outer end of the main member, the attachment further having a fastening device at its outer end for fastening the same to the stove-pipe substantially as described.

2. As a new article of manufacture, a stove pipe attachment, consisting of an elongated main member or body having a laterally projecting spring arm at its inner end, a spring coil at its outer end and a returned spring arm extending from said coil, said arm being yielding from itsconnection with the coil for adjusting itself to the thickness of a chimney wall, the attachmentfurther having a fastening device at its outer end for fastening the same to the stovepipe substantially as described.

3. As a new article of manufacture, a stove pipe attachment consisting of an elongated member or body having a spring arm at its inner end, a spring coil at its outer end an arm returned on the main member from said coil and yielding from its connection with the latter, and a separate anchor having a loop loosely embracing such outer coil to move thereon, the free end of the anchor having a bent, pointed termination, substantially as described.
