' QQMBINED FIRE-Por AND T WYERQIRON.

10 @LZ whom it mag/concertar Be it known that I, CHARLES 0. SwENsoN,

a citizen of the United States, residing at Minneapolis, in the county of Hennepin Aand 5 State of Minnesota, have invented certain neWand useful Improvements ina Combined FireePot and Twyer-Iron; and'I do declare the following to be a full, clear, and eXact description ofthe invention, such as will enable 1 1o others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to l the figures of reference marked thereon,which form a part of this specification.

i5 My invention relates to blacksmiths forges.

It has special reference to the parts known to the tradeand art as the nre-pot andthe twyer iron, and the main objects are,

first, to provide an improved combined twyerzo iron on lire `pot;` second, to further improve upon the construction set forth in my United States Patent No.v 792,179, issued on the 13th of June, 1905, partly by simplifying and cheapeningthe sameand partly by emz 5 bodying important features which by misunderstanding and errors were omitted from said application and patent. These and other objects I attain by the novel construction and'arrangement of parts illustrated in 3o the accompanying drawings, in which-f Figure 1 is atop view of my improved repot and twyer-iron. Fig. 2 is a vertical -central sectional view of same on the line a a in Fig. 1. Fig. 3 is a top view of the upper flange 3 5 12 of the tWyer-iron.

of the twyer-iron, showing the means by which the ashes and cinders arelet out from the ashpan. Fig. 5 is adetail top view ofthe draftregulator.

4o n Referring tothe drawings by referencefnu# l merals, 1 designates the fire-pot, whichis cfa v substantially circular concaveform, With two diametrically opposite depressions 2 anda central-blast opening y 3,below which is a `45 hemispheric concaveli, in which is' mounted von a horizontal rocking rod or shaft 5 a sub-v stantially globular body or damper 6,' pro. vided-v'vith'pra'cticall central-blast openings 7, Lforming a centra blast, While .collars 8 I 5o aboutthe rock-shaft holdy the damper in al f vcentral* position in the cavity 4,y so that practically all around the damper is-formed a side blast, which in combination with the 'center blast forms avery -eective blast, producing -5 5 the most efficient fire.` Said fire-pot is also specification of Lettersratent.

formed with a base-flange 9, which is so large that it`holds the fire-pot very'steadily'` ported upon the surrounding bottoni' `or base 10 ofthe forge or hearth thereof. In my forn mer patent above referred to said flange was so'small that it had-t0' rest .on sup ortingbars, which involved more expensefboth in i material and labor than to simply make ,the flange wider; At the under side of said flange l9 .are provided'in circular order yguiding-liigs l,6.5 1 1, between which is ,centrally guided .the upperflange 12 *cfa vertical .cylinder orltuhe 153, having a lateralk branch 143,`through which it f receives windfromthe blower. (Not shown.) i

Said tube 13 is suspended from the'flre-pot 7o` by the bolts 15, inserted in holes 16 in the latter and in quadrantal slotsy 17 in the flange- 12, so that the position of the depressions .2 in the fire-pot maybe changed from a longitudinal to a transverse position with reference 75 to the rock-shaft 5 or thetube 14.- Y

. In Fig. 3, 18. designates grooves in lthe flange 12 for the shaft y5. n f

The lower end of the tube 13 has at one side a lug 19, to which is pivoted a horizontally- 8o swinging lid 20, having a handle 21v stopping against and normally resting in a hook 22, formed upon the opposite side of the tube. Said lid serves as the outlet for asles and cinders accumulating inthe lower half of the 8 5 'tube 13. The purpose of the depressed portion 2 2 is to form a valley for tires and other irons of some length to get them in proper position in the fire- It will be observed that although the flange 9o 9 is wide enough to answer the purposes described the structure -is still inexpensive,

since the flange only connects with the firepot by a reduced neck 23. It will also be understood that the valve or yblast-regulator 6 cave inthe lowerpart thereof, of alhorizon- 1o 5 .tally-arranged rock-shaft and a substantially centrally perforated blast regulating piece mounted on the shaft in said concave in such a manner that van opening for side blast is formed betweenthe valve and .the fire-pot, 11o`f .ile-pot having in its upper edge diametri@- vally opposite depressions and in its bottom bolts extending down through said slots and being provided with nuts below the flange 12, said fire-pot also having a central opening dirrectly over the blast-regulator and a iiange adapted to rest upon the hearth of a forge and hold the tube 13 suspended in an open- Y ing therein.

3. The combination with the vertical tube 13 having the side inlet 14 and means for closing its bottom end, of the upper flange 12 formed on said tube and having oppositely# disposed quadrant'al slots and the grooves 18, a rook-shaft in said grooves and a erforated valve-piece or blast-regulator on t ie shaft, a lire-pot having in its upper edge diametricallv opposite depressions and in its bottom bolts extending down through said slots and being provided with nuts below the iange 12 i said fire-pot also having a central opening directly over the blast-regulator and a flange adapted to rest upon the hearth of a forge and hold the tube 13 suspended in an opening therein, said iire-pot also having at its bottom side guards engaging the flange 12 to help hold the tube in'oentral position.

In testimony whereof aflix my signature in presence of two witnesses.
