UNITED STATES JAMES SETCHFIELD AND WILLIAM J. MUIR, 0F PORTLAND, OREGON.

DAM'PER FOR FIREPLACES.

Application filed January 4, 1922. Serial No. 526,897.

To all wiz/0m it may concern:

Be it known that we, JAMES Sn'rCHrrnLn and WILLIAM J. MUIR, citizens of the United States, residing at Portland, in the county ot Multnomah, State of Oregon, have in-A vented certain new and useful Improvements in Dampers for Fireplaces; and we do hereby declare the following to be a full, clear7 and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in fire-place structures, 'and particularly to dampers therefor.

The primary object of the invention is to provide a frame for the damper which is properly seated and constructed in the top of the fire-place. i

Other objects and advantages in the invention will be apparent in the following description when taken in connection with the accompanying drawing. y

In the drawing Figure 1 is a front elevation of a fire-place made in accordance with the invention.

Figure 2 is a vertical central sectional view on an enlarged scale.

Figure 3 is a horizontal sectional view through the lire-place on the line 3 3 oi Figure 1.V

Figure 4 is an enlarged perspective view of the damper and frame removed from the fire-place.

Referring particularly to the accompany ing drawing, 1() represents the front ot the brick work of the fireplace. 11 the floor thereoi"` 12 the arched rear wall, and 13 the vertical side walls.

It will be noted that these side walls are not parallel and extend in convergent relation toward the rear concaved wall 12, whereby the width o'l" the fire-place is narrower than the mouth of the opening, in the plane of, the floor 11. Above the rear wall 12 extends a vertical fine 14, the wall 12 having its upper end curved forwardly and 'forming with the top of the fire-place an opening. An angle iron strip 17 is secured to the arch oiE the fire-place. Resting on the upper end of the arched wall 12, and on the angle plate 17 is a metal. box or casing 20, said box as seen in Figure 4 including the higher front wall 21 and the lower side walls 22. The upper portion of the front wall 21 is inwardly directed to provide a ledge 34 which assistsin supporting the front wall of the fire place.

Extending on the inner faces of the side walls 22 are the inwardly and upwardly inclined ledges 23, on which the. damper is adapted to rest when closed. At the point ot' juncture oi this frame 23 with the 'front wall 21, is a longitudinally extending ledge 24. At each end of this ledge are arranged vertical spaced lugs 25, between which are engaged the pintles 2G oil the damper 27. These pintles 26 are formed by cutting away the rearward portion of the end .edge of the damper as shown at 35. This damper rests in an inclined position on the upper faces oi the ledges 23, as is rlearl seen in the sectional view of Figure 2. Tie upper tace of.' the damper 27 is formed with a longitudinally extending' rib 28, the center of which is higher than the ends and is formed with an upstanding lug 29 adapted to strike against the inner face or' the iront wall 21, when said damper is raised above the frame 23. A vertical apertured lug 30 is formed on the forward free edge of the damper 27 and has connected thereto one end of a chain 31, said chain extending through a metal tube 32 which is secured in and extends through the front Jface of the fire-place, where said chain is provided with a hand hold 3'3 for manipulating the damper.

ln the dotted open position of the damper 27 seen in Figure 2, the lug 29 engages the front plate 21 to prevent the damper from rising to a vertical position, or into a position beyond the vertical and against the side walls 22. Thus the damper is at all times ready to gravitate into closed position when the chain is permitted to pay out through the metal tube 32.

What is claimed is.

1. The combination with a fire place having a rear wall and a front wall supporting angle plate, of a damper therefor, comprising a substantially rectangular casing having approximately vertical front and rear and side Walls, the upper portion of the sai-d front wall being inwardly directed to form a wall supporting ledge, the said cas" ing resting upon the said rear wall of the lire place and the angle plate, upstanding lugs positioned on the inner faces of the side walls, and a damper plate positioned within the casing, the said plate being out away to form pintles which are received between the said lugs.

2. The combination with v,a tire place having a rear wallv and a front wal'lrsupporting angle plate, of a damper therefor, comprising a substantially rectangular ,casing having approximately vertical front and rear and side walls, the upper portion of the said front wall being inwardly directed to form a wall supporting ledge, the said vCasing resting upon the rear wall of the fire place and theangle plate, theinner faces ot' the side walls of the casing being provided with inwardly and upwardly inclined ledges and the front wall of the casing being provided with a longitudinally extending ledge on its inner face, the said side walls being further provided on the inner faces thereof with upstanding spaced lugs, and a damper plate arranged to rest upon and be supported by the said ledges within the casing, the rearward portion of each of the end edges of the said damper plate being cut away to form pintles'which are received between the -said spaced lugs.

k3. A damper for a fire place comprising a substantially rectangular casing having approxiniately vertical front and rear and side walls, the upper portion of the said front wall being inwardly directed to form :l ledge, and a damper plate positioned within the casing, the said side wal-ls being provided with upstanding lugs on their inner faces, and the said damper plate being cut away to forni pintles which are received between the said lugs.

4. A damper for :a lire place comprising a casing having substantially vertical front and rear and side walls, the said side walls being provided with upstanding spaced lugs, and a damper plate positioned within the casing, the said damper plate having the rearward portion ot each of its end edges cut away to orni pintles which are received between the said lugs.
