SPECIFICATION forming part of Letters '.Patent No. 535,466, dated March 12, 1895.
Application led December 13, 1894.. Serial No. 531,678. (No model.)
place grates, and particularly to the damper and means for operating the same.
This invention -is also an improvement upon my application, Serial No. 524,747, filed October 2, 1894, and relates only to the novel construction of the sectional damper and the means for operating the same.
The object of this invention is to greatly simplify the construction so that the grates can be made cheaper and easier than the old style or pattern.
With this object in view, the invention consists in the details .of construction and` novelties of combination, all of which will be fully described hereinafter and pointed out in the claim.
In the drawings forming a part of this specication, Figure l, is a face view of a mantel provided with one of my improved grates. Fig. 2, is a horizontal section on the line 24-2 of Fig. l. Fig. 3, is a vertical section, and Fig. 4, shows the details of construction.
In carrying out my invention, I employ a re place grate A, having a flat top b, and formed with an opening b at the front, which opening permits the products of combustion to pass from the grate to the chimney flue. The top plate of the lire place has a series of openings C, and sliding upon said top plate is a damper C', also provided with a series of perforations, said damper sliding between guides C2, C2, arrangedupon the top plate of the lire place.- A lever C3, is pivoted upon one of the guides and works in a slot in the other slide, said lever being connected' near the rear end with the damper C', and at its forward end is connected with a handle C4, whichworks in a staple c fastened to the face of the tire board. By sliding the handle back and forth, the damper C', can be regulated as desired.
This damperis intended for use after the fire has been started, and when the lire is started, I employ a large damper D, which is intended to cover the opening b', and is made in two sections D,and D2, pivotedl at their outer ends at d, and connected at their inner ends by means of a slot D3, and pin D4, the
` slot D3, being producedin the section D2, and
the pin D4, carried at the end of the section D', said sections being so united that the entire damper can be moved forward to close the opening without straining any of the connections.
A single link E,is employed to operate the damper, said link being hook-shaped at its rear end e, to embrace the damper as shown in Fig. 3, and at its forward end, it is bent `down as shown at e', to pass down through the lower end of a lever F, pivoted atf, upon the rim of the tire place grate.
The lever is curved down and rearward as shown to moreeasily receive the end e.
The construction and arrangement just described is much simpler than that formerly used, and is easier and cheaper to make.
Having thus described the invention, what VI claim, and desire to secure by Letters Patent, is-
In an open fire place grate, the combination with a case, of the damper D, composed of sections D', and D2, having a pin D4, and slot D3, respectively, whereby said sections are connected, and a link E, and lever F, for operating the said sections of the damper simultaneously, substantially as shown and described.
In testimony whereof I afx my signature in presence of two witnesses.
