SAMUEL MCLAUGHLIN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND BENJAMIN R. OASKEY, OF SAME PLACE.
Letters Patent N 0. 100,30S, dated March, 1, 1870.
IMPROVEMENT IN -IP'IJ'DDLING-IEURNAIIS.
The Schedule referred to in these Letters Patent and making part of the same I, SAMUEL MCLAUGHLIN, of the city and county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in the Construction of Puddling-Ifurnaces, of 'which the following is a specification.
The nature of my invent-ion consists in so shaping the exterior iron plates which inclose the furnace and hearth, that they conform to the shape ofthe hearth,
and thereby make a'great saving in the amount of fire-brick and material used in its construction, whereby also the lining of fire-brick can be made thicker and more durable on the jamh of the door; also in the mauner of securing the door-frame to the said iron plates.
In the drawing accompanying this specification- Figure 1 is a plan of my furnace. Figure 2 is alongitudinal section. The furnace with the grate-bars beneath is shown at A' Tlie hearth where thepuddling is performed at B. C is the chimney. I
The exterior of the furnace is made of cast-ironplates D D' D" 'D' bolted together by anges and bolts, as shown at g.
Puddling-furnaccs as now made have the plates D D' in one` straight line, the size and shape of the lireplace and hearth being made by filling in with brick plates D swell outward, either by a curveor in angular lines, so as to conform to the shape of the hearth, which is usually of an elliptical form.
The interior side of the plates D D' are then lined with a course of fire-brick, which is brought up with an even thickness of about nine inches close to the door-frame H.
The plates D" gradually converge to the chimney, which is the narrowest part of thefurnace.
The door-frame H is constructed with a flange, h,
fitting against a corresponding flange in the plates D', so that the'interior of the door-frame is iush with the interior of the cast-iron plates D', thus rendering it much less liable to.be burned away, and the fire-brick much more. easily fit-ted. This door-traine Il is curved outward, as shown for a similar object.
By this mode of construction a uniform thickness of fire-brick, Ii, may be used both front and back of the hearth, costing less in construction, being more durable, and more economical in fuel.
WhatI claim as my invention, and desire to secure by Lettersv Patent, is
l. rPhe casing plates D D', also the door-frame H, swelled or curved outward, so as to conform tothe shape of the hearth, in the manner herein shown and i described.
2. 'Ihedoorframe H, rabbeted 0r flanged'as shown, so as to bring the inside flush on aline with the inside ot' the casing plates D', substantially as described.
v SAMUEL MCLAUGHLIN.
