STOVE PIPE ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application letl January 2, 1907. Serial No. 350,483.

To all whom it may concern:

Be it knownthat I, LEWIS REASER, a citizen of the United States, and a resident of the city of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Stovepipe Attachments, of which the following is a speciiication.

My invention relates particularly to the class of draft regulators shown in Patent No. 619,993, issued to me February 21st, 1899, in which a damper rotatably mounted in the stove pipe is employed in coperation with a movable side wall damper plate; and it consists in certain improvements which are fully described in connection with the accompanying drawing and the novel features of which are specifically pointed out in the claims.

Figure 1 is an elevation of a vertical smoke pipe having my improved regulator applied thereto, the slide plate being shown raised and the adjusting handle unlocked and swung to one side to clearly show the damper connecting rod. Fig. 2 is a longitudinal sectional view taken on the line 33 of Figs, 1 and 3. Fig. 3 is a sectional plan view of the same on the line 2 2 of Fig. 1. Fig. 4 indicates a modification in which my improved mechanism is adapted to a horizontal smoke pipe.

The circular damper plate 1 is rotatably mounted in the pipe 2 by means of trunnions 3 4, one of which is preferably squared on its projecting portion to permit the use ofa turning handle thereon when employed as indicated in Fig. 4. This damper is also formed with a rod engaging eye 5,-preferably duplicated as shown -to provide for conveniently reversing it as may be required.

The wall opening 6 in the pipe, which is of approximately rectangular form as shown, is located above the rotary dalnper 1, and is provided with a rigid integrally formed frame 10 secured to the edges thereof. This frame has outwardly turned portions 11-12 forming parallel guide ways for engaging the opposite edges of a curved cover plate 13 for said opening 6; said plate being slidable in said Ways to regulate the opening 6, and having a rod-engaging slot 14 or the damper connecting rod 15. The frame 10 is also provided with a catch 7 for the adjusting handle hereafter described. This rod l5 is formed with a tee-head` 16 adapted, when turned transversely of the cover plate, to be passed through the slot 14 therein so that when in normal vertical position the rod will be movable with the plate. Its opposite inner end is formed with a hook 17 which may be conveniently engaged in the eye 5 of the rotary damper; which latter it thus serves to connect with the slidable cover plate 13 so that they will be simultaneously operated,-the one being closed as the other is opened and vice versa. `For thus jointly operating the connected sliding and rotating plates, I employ, as shown in Fig. 1, a handle 2() having a slotted end 21 adapted to be removably engaged with the projecting tee head 1G of the damper connecting rod 15; said handle being provided with a series of openings 22 for adjustably engaging the frame catch 7 and so holding the damper in adjusted positions.

It Will be noticed that the several moving parts of my mechanism are readily assembled in operative connection with thejpipe without any riveting or bolting and that the operation is as simple and satisfactory as the construction.

When it is applied to a horizontal smoke pipe, as indicated in Fig. 4, a suitable handle may be connected to the rotary damper trunnion 4 as already stated, thus operating the slide plate indirectly instead of directly as in Fig 1.

What I claim is:-

l. The combination with a pipe having` a wall opening with a slidably mounted cover plate therefor having a slotted opening, of a damper rotatably mounted in said pipe and having a rodengaging eye, and a connecting rod having a hooked end removably engaging said eye and a tee-head removably engaged in said slotted opening substantially as set forth.

2. The combination with a pipe having a wall opening with a slidably mounted cover plate therefor having a slotted opening', of a damper rotatably mounted in said pipe and having a rod-engaging eye, a connecting rod hayYA ing a hooked end removably engaging said eye and a teehead removably engaged in said slotted opening and projecting therethrough, and a handle for adjusting said slide plate removably attached to said projecting tee-head, substantially as set forth.

In testimony whereof, l affix my signature, in the presence of two witnesses.

LEWIS REASER.
