To all whom it may concern:

Be it known that I, CALVIN A. LITTLE- FIELD, of Covington, Kenton county, Kentucky, have invented a certain new and useful Improvement in Fireplaces; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

My invention relates to fire places having air heating apparatus through which air may be passed, heated, and conveyed for room warming purposes to any part of a building; and consists in an arrangement hereinafter described of hollow crown and hot and cold air passages.

In the accompanying drawings Figure 1, is a vertical section of a fire place embodying my improvement. Fig. 2 is an elevation of back part with wall removed. Fig. 3 is a horizontal section on line it 02, Figs. 1 and 2.

A is the fire place setting, B B the chimney fines and C the grate.

l) is a bonnet forming a smoke conductor, fixed as shown over the fire place.

E is a chamber in which cold air from the outside of fire place is allowed to enter, forced to circulate and become heated. It is set in the brick work as shown directly over the fire grate and communicates with the outside of fire place through an opening F, and through opening G with a tube H passing upward between flues B B and is used to convey the heated air to parts of building desired. Conveying tube H is provided with suitable register or registers I. The heater E is fitted with a partition 6 devised to cause the air to properly circulate through the heater before entering tube H.

The direction of the current of air is represented by arrows. Qhe opening F is provided with a door f used to regulate the supply of cold air to the heater.

An opening K provided with suitable door is, is allowed at times to supply cold air to the conveying tube H, with which it directly communicates, to unite with the air passed through heater E and thus regulate the temperature of air passed through tube H to suit the requirements of rooms be ing heated.

By proper adjustment of doors 7 and Z the temperature of air passed through tube H may be regulated as desired.

1 am aware that chambers have been applied behind and around fire places to heat air and supply the same to other apartments and also that arching crowns have been employed having the same eifect upon the firc and fine as my hollow crown E.
