IMPROVEMENT IN. FURNACES FOR BLANKS.
Specification forming part of Letters Patent No. 180,698, dated August 8, 1876; application tiled January 22, 1876. K
chamber, for the protection of the operator from the flame, which puffs out when the doors are suddenly opened.
The accompanying drawings are as follows:
' Figure l is a top view of a self-feeding baseburning furnace, showing the top of the coal magazine, the doors for covering the openings therein, the top of the heating-chamber, the links for raising the doors of the heating-chainher, and the upper edges of my'deflectingshields. Fig. 2 is a longitudinal vertical section of the furnace, through the line a; m on Fig. 1. Fig. 3 is a transverse vertical section through the line 3 3 on Fig. 1. Fig. 4 is a transverse vertical section through the line 2 2 on Fig. -1
The drawings represent a base-burning coal: magazine, A, having its bottom composed of grate-bars a, arranged over a closed ash-pit, B, provided with openings b, for the inlet of blasts of air, by the operation of which the gaseous products of combustionare driven into the lateral heating-chamber C, from the bottom of which they are discharged in a downward direction, through the vertical eduction-passages D, into the chamber D, which is to be connected with a sewer or pipe leading into the open air, as may be most convenient.
The heatingchamber is provided with openings c c at the ends, which can be closed by furnace, immediately opposite the openings,
are pivoted shieldsff. A recess is formed on inner side of the shields, for the purpose of laterally deflecting the flame of hot air which puffs out of the opening 0 when the door 0 is raised.
My improved furnace is operated in substantially the same way as the furnace described in my Patent No. 166,335, but by means of my improvements I am enabled to use, if required, a strong blast of air.
, By providing outlets for the carbonic-acid gas in the door of the chamber, and conducting the gases downward, I economize in fuel; and utilize theheat of the furnace to the fullest degree, for the purpose of heating blanks deposited in the heating-chamber. At the instant of opening the door into the heatingchamber to introduce or remove the metal bars or blanks therefrom, there is an outward puff of hot air or flame, which my shield defleets laterally, and which is thus prevented from endangering the safety of a person standing opposite the opening. After the first putt the pressure within the furnace is relieved, and the shield may then be safely raised, allowing access to the heating-chamber.
I claim as my invention in a self-feeding furnace for heating blanks, provided with a baseburuing coal-magazine 1. A closed ash-pit and a blast-pipe for the supply of air, in combination witha lateral heating-chamber, having outlets in its bottom or floor for the discharge of the unconsumed products of combustion in a downward direction, substantially as described.
2. In combination with the opening and inside door of a heating-chamber, the deflectingshield, for the purpose of laterally deflecting the hot air puffed out of the opening when the door is opened.
