Application filed November Be it known that I. l hnnsnmnlf. Picn- DER, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful.Improvements in Furnaces, of which the following is a specification.
This invention relates to oil furi and it comprises a furnace having agrate .rormed of fire bricks arranged on suitable supports,
the fire bricks being); spaced from each other to form openings for the passage of air through the grate, spacing blocks to retain the fire bricks in proper position, dampers arranged beneath some of said openings to permit variation in the amount of air delivered. to the furnace, and means for operatsaid dampers.
An object of the invention is the provision of an oil furnace having a plurality'of openings capable of furnishing sufficient air to support combustion of the fuel when the furnace is operated at its maximum capacity, some of said openings being; provided with campers wherebythe supply of air may be diminis ied when the furnace is operated below maximum capacity. p
A further object'of the invention is the provision of grate having transverse supports and spacing blocks secured thereto to retain th fire bricks forming the grate in proper position.
iii-further object is the provision of means for controlling the dampersfrom the outside of the furnace.
In the accompanying drawings, I have shown one embodiment of the invention. in this showing:
Figure 1 is a horizontal sectional view through a furnace on a line above the grate,
Figure is a vertical. longitudinal sectional view on line 2-2 of Figure 1.
Figure 3 is a similar view on line -3--3. of Figure 1, i
Figure 4; is a transverse vertical sectional view on line 4i4 of Figure 1,
Figure 5 is a detail view of the grate supporting; -mechanism, and,
Figure 6 is a detail view of a portion of the damper operating; mechanism.
Referring to the drawings, the reference numeral 1 designates the front wall of a furnace and 2 the rear wall. The furnace is provided with side walls 3. Crude oil or other fuel is delivered to the furnace through a pipe 3 extending underthe grate and 7, 1921. Serial No. 513,503.
compressed air delivered through a similar pipe 4-. The burners may be arranged at the front or heel; of the furnace, as desired. In the present illustration, 1 have shown a back shot furnace in which the pipes 3 and 4c communicate with vertical pipes 5 in which the fuel is atomized and delivered therefrom in the form of a spray, indicated at 6.
The grate is supported by means of a longitudinal bar 7, the ends ofwhich are received in-the front and rear walls of the furuses. 'This bar is provided wi h suitable notches 8 in its upper face, for the reception of transverse supporting bars 9. A plurality of these transverse supporting bars are provided spaced from each other at suitable intervals. The distance between the transverse supporting bars is equal to the width ofan ordinary fire brick and the grate is formed of a plurality of fire bricks 10 which are supported on horizontal flanges 11 of the transverse supporting bars. At suitable intervals, the grate is providedwith openings 12. tdpacing blocks 13 are, arranged in these openings and secured to the transverse supporting bars by means of bolts 14-. It will be apparent that the use of bolts or other securing means to retain the spacing blocks in position prevents relative movement of the fire bricks and thus insures proper arrangement of the parts forming the grate.
The number of openings 12 is determined by the amount of air necessary to completely burn the fuelwhen the furnace is operating at its maximum capacity. When operating below maximum *apacity, it is desirable to cut down the supply of air in proportion to the reduction in the amount of fuel delivered to the furnace. Certain of the openings 12 are provided with dampers 15 which are pivotally mounted brackets 16 carried by the transverse supporting members. These dampers may be provided with faces 15, formed of insulating material. These brackets also form bearings for transverse shafts 16'. Levers 17 are keyed to the shaft to revolvetherewith. These levers are connected to the dampers by means of links 18. @ne of the levers is provided with an extension 19 which is connected to a rod or lever 20 extending longitudinally of the furnace and' passing through the front wall. As shown, the dampers are arranged in transverse rows and a plurality of them are conor other compressed gas is at 153A .nected to each of the levers 20. Theforcrank portions 26 to move levers 23 downwardly. moves the control levers 20 outwardly and opens the'dampers. open, the control member 32 may Ward end of each of the levers 20 is connected to a bell-crank lever 21 pivotally mounted in a bracket 22 arranged on the front of the furnace. The other arm of the bell-crank lever is connected to a vertical lever 23. This arms provided with an e11tens1on carrying a counter weight 23. It )late orbear- I secured to the front of the furnace a plurality 01' the ing 24L is by mea-ns of brackets 25 and arms 26, corresponding in number to levers 20 are jouinaled in this plate. One
end of each arm. is provided with a crank 1 I 1 {Li 1 1 po t1on 27, connected to tie rel aca eieis 23 and the opposite ends are connected to 28 which are connected to he ends 01'? the coil spring-gs coil springs 29.

bricks isprevented and The construction of the grateis advantageous in that relative movement of the fire the openings remain of uniform size at all times. By means of the supports having horizontal flanges, ordinary lire bricks may be employedin the place of specially constructed and relatively expensive bricks or blocks.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts maybe resorted to withoutdeparting from the spirit of the invention or the claims.
