`ALBERT G. MANN, OF WORCESTER, MASSACHUSETTS.
Letters Patent No. 101,143, dated rlfarchy 22, 1870.
IMPROVE!) TWEBR.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern: I
Be it known that l', ALBERT G. MANN, of the city and county of Worcester, and Commonwealth of li'iassachusetts, have invented certain new and useful lmproveiuents in Tweer-Irons; and I do hereby declare that the following is ai'ull, clear, and exact description of the same, reference being had to the .accoinpanyiug drawings forming part of this specification, and in whchl Figure 1 represents a top or planvvicw of my iinproved twecr-rou, one of the air-slides or valves being shown partly drawn out, and
Figure 2 represents a section of the same. on line A B, fig. 1.
To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it'more iu detail.
'lhe nature of my invention consistsy First-,in the combination with the wind-box of the rotating tire-support and two notched slides or airvalves, as and for the pul'poses hereafter explained.
Second, in the improved tweer-iron, having the parts of which it is composed constructed and combined together as hereinafter specied.
In the drawingsf- The part marked A is the wind-box and ash-pit, yhaving a tlanged top, B, with a square or rectangular hole or opening, C, in the center, which is closed partly by two notched slides or air-valves, D D, which are iitted to slide in ways er guides a a under the iianged top B, and partly by the rot-ating tire-support E, the edges b b oi' which are made in the form of segments of circles, with a convex iop and bottom, c,
4all of which is fully indicated in fig. 2 of the drawings.
'lhe slides are provided with handles F F, by which they can be operated, while the tire-support E is attached to a spindle, Gr, which is fitted to turn in bearings in the box A.
One'end ot' the spindle G extends out, and is provided with a forked handle, H, shown in tig 1, by
means of which theiire-support E can be rocked upon its center or rotated as occasion may require, to lighten up the fireV orto dump the einders.
lhe bottom I of the box A is provided with a handle, J, by means of which it can be drawn out as occasion may require, to discharge the ashes and cinders.
By means of the notched slides or air-valves D D the current ot' air allowed to pass up through the tire. can be regulated at pleasure, and also directed to any particular point upon the tire-support E. For instance, it' it be desired to have a current of air at one end of the tire-support on one side, and in the middle on the other, the slides are drawn into the positions shown in fig. 1, and if it bc desired to have the currents of air opposite each other and near the center of the fire-support E, the slides are moved to bring the notches d d opposite each other.
By the use of the double concave fire-supportE the coal can belightened up and freed from'ashes in a very convenient manner, and that, too, without throwing the fire from a' central position. The double concavere-support E could beapplied to good advantage iu the center ot' a fire-grate, for livening up the coal and freeing it from ashes and cin ders.
The air is admitted to the box A through a pipe, K.
Having described my improvements iu tweerirons, I
Vhat I claim Vtherein as new and of my invention, and 'desire to secure by Letters Patent, is
1. The combination with the wind-box of thcrotating iire-supportE and the notched slides or air-valves D D, substantially as and for the purposes set forth.
2. The improved tweer-iron herein described, having the parts of which it is composed constructed and combined together in the manner set forth.
A.. G. MANN.
