STOVE-PIPE AND COLLAR FASTENER.

SPECIFICATION forming part of Letters Patent No. 468,629, dated February 9, 1892.

Application filed April 11, 1890. Serial No. 347,441. (No model.)

To all whom it may concern.-

Be it known that I, JOHN J. TRAVIS, a citizen of the United States, residing at Three Rivers, county of St. Joseph, State of Michigamhave invented a new and useful Stove-Pipe and Collar Fastener, of which the following is a specification.

This invention relates to that class of devices for locking the pipe in the chimney, and which employsa rod attached to the pipe and having an angled end for engaging the inside of the chimney, and in which is employed a lock-plate for clamping the collar which surrounds the pipe against the chimney.

The object of the invention consists in certain new features of construction, in combination with old features, designed to effect greater utility.

In the drawings forming a part of this specification, Figure 1 is a side elevation with parts broken away. Fig. 2 is an enlarged lettered detail from Fig. 1 in perspective; and Fig. 3 shows enlarged broken details from Fig. 1, showing changes.

Referring to the lettered parts of the drawings, A represents the chimney, and B the pipe inserted into the thimble or pipe-hole z of said chimney.

At 0 in Fig. 1 is shown a rod turned upward at each end at right angles. One end of this rod engages the inner surface of the chimney above the thimble or pipe-hole, while the other end is threaded, as at a, and passes up through a hole in the pipe B. This threaded end a is provided with an adjustable nut c, which forms a shoulder against the interior surface of the pipe at a point where the threaded end passes up through said pipe.

At D is a lock-plate provided with an elongated slot S and an angled end '0, which end clamps against the collar N and holds it in close contact to the chimney. The threaded end a of the red 0 comes up through the slot S, and by means of athumb-nut screwed onto the threaded end a of the rod 0 the lockplate is not only firmly clamped to the pipe B and against the'collar N, but by means of the shoulder a the rod 0 is held at a proper angle and in a firm manner. The shoulder C also completely closes the hole in the pipe through which the threaded end of the locking-rod O is passed, thus preventing any escape of smoke into the room and any interference with the draft. By adjusting the nut a up or down the proper angle is given the upturned end which comes against the inside surface of the chimney, according to the variations of the surface, and at the same time have the angled end of the locking-rod O which is in the chimney, extend well upward to obtain the proper engagement with said inside surface of the chimney. Still by loosening the thumb-nut the rod 0 will readily tilt down, so as to remove the pipe from the chimney.

In Fig. 3 the end 1) of the lock-plate D is shown rigidly attached to the collar N, while in Fig. 1 these parts are separate. The former plan is quite desirable for the reason that any movement of the collar N to adjust it to its proper position will also adjust the lock-plate. The lock-plate has an angled end h, provided with a hole for the attachment thereto of a wire c,-Fig. 1. The left-hand end of the wire e is here shown broken, but the design is to attach said end to the pipe at some suitable point-as, for instance, at the turn of an el bow-and thus not only looks the pipe in the chimney, but looks the joints of a pipe together by means which are attached to said chimney.

Referring again to the nut c, which forms a shoulder 011 the threaded part a of the red C, this shoulder maybe of integral enlargement on said locking-rod, if preferred.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-- In a stove-pipe and collar fastener, the combination, with a length of stove-pipe having a hole in its upper side near one end, a collar on the pipe between the hole and the end nearest thereto, an exterior locking-plate secured at one end to the collar and provided intermediate its ends with a longitudinal slot registering with the hole through the pipe, a tie-wire attached to the outer end of said plate and adapted to be connected with the pipe beyond the joint between said length and the remainder of the stove-pipe, a rigid locking-rod within the pipe, the ends of which are bent at substantially right angles thereto and one of which ends extend beyond the end outside ofv the plate for clamping the parts to- 10 of the pipe and is adapted to engage with the gether, substantially as described. interior of the chimney, and the other end is In testimony of the foregoing I have heresereW-threaded and projects up through the unto subscribed my name in presence of two 5 hole in the pipe and the slot of the lockingwitnesses.
