ANNEALlNG-FURNACE.
SPECIFICATION forming part of Letters Patent No. 786,565, dated April 4, 1905.
Application filed September 16, 1904- Serial No, 224,658.
To all whom it may concern.-
Be it known that I, JOHNSON HUGHES, a'citi zen of the United States, residing at Wissahickon, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Annealing-Furnaces, of which the following is a specification.
The leading object of this invention is to provide a furnace having means for simulta neously handling; several lots of material as independent units, so as to treat the several units simultaneously, as each may require.
The nature and characteristic features of the improvements will more fully appear by reference to the following description and the accompanying drawings in illustration thereof, of which Figure 1 represents a plan view, partially in section, of a furnace embodying the improvements. Fig. 2 represents a side elevation and partial vertical section of the same. Fig. 3 represents a transverse vertical sectional view thereof, and Fig. 4 represents a longitudinal sectional view of a form of clutch that may be employed in practice of the invention.
As shown in the drawings, the furnacechamber 1 has in its bottom 2 the longitudinal channel 3, communicating with the several transverse fiues 4. At its top the chamber 1 has the burners 5 located in its side walls to produce a flame at the top thereof, and the several flues 4 are provided with dampers 6, by which the distribution and courses of the flame and hot gases may be controlled at will, the dampers being held at any desired position by means of the counterweights' 7, having therewith the flexible connections 8, passing over the supporting-wheels 9.
able, but revolubly held to the shaft by means of the spline 28.
Several tables 11, loaded on rollers 10 exterior to the furnace-chamber 1, may be passed through the door 29 in succession. The entering table is held in a current of modified temperature passing through the first fine 4! until the material has received its initial heat, when it is moved by the set of rollers on which it stands into the current of higher temperature passing through the second flue 4. This charge, while held stationary upon its set of rollers to acquire the higher temperature, is followed by a second charge of material, which is in like manner given its initial heat by the current passing through the first flue4 at the same time that the first charge is being raised to the maximum temperature desired. When the first charge has been sufliciently heated, it is moved to the next. set of rollers in the path of the modified current passing through the third fine 4, and the temperature is here drawn down to the point desired at which the charge is passed out of the furnace through the door.29, the second and further charges being treated in like manner. As the mate rials carried by different tables are frequently of different size and character, it is sometimes desirable to hold particular charges in the furnace and at different points in the furnace a longer or shorter period than others,-
and this may readily be accomplished by the present improvements,sin ce each set of rollers is capable of being operated or thrown out of action to handle any particular charge independently of the others, and the intensity of the several currents may be regulated at will. aving described my invention, I claim- In an annealing-furnace, aheating-chamber, a plurality of sets of rollers for carrying materials in said chamber, and means for operating said sets of rollers together or separately, substantially as specified.
2. In an annealing-furnace, a heating-chamber, means for simultaneously varying the intensity of the heating operations at different zones of said chamber, a plurality of sets of rollers for carrying materials in said chamber, and meansfor operating said sets of rollers together or separately, substantially as specified.
3. In an annealing-furnace, a heating-chamber, means for introducing a flame near the top of said chamber, flues at various points along the bottom of said chamber for discharging the products of combustion, dampers for regulating said fines and controlling the heating-currents in said chamber, a plurality of sets of rollers for carrying materials in said chamber, and means for operating said sets of rollers togethertor separately, substantially as specified.
4. In an annealing-furnace, a heating-chamber having a channel extending along the bottom thereof, rollers extending across said channel and located below the general level of the bottom of said chamber, flues at several points along the length of said chamber for carrying off the gaseous products of combustion therefrom, dampers for controlling the respective flues, and means, for heating said chamber, substantially as specified.
5. In an annealing-furnace, a heating-chamshafts respectively geared to a plurality of said rollers, a driving-shaft, and means for connecting and disconnecting said drivingshaft with relation to each of said first-named shafts, substantially as specified.
6. In an annealing-furnace, a heating-chamber, rollers extending through and beyond the ends of said chamber for carrying materials thereto, therethrough and therefrom,
shafts respectively geared to a plurality of connecting said driving-shaft with each of said first-named shafts, and a clutch for engaging and disengaging said driving-shaft with each of said first-named shafts, substantially as specified.
In testimony whereof I have hereunto set my hand, this'14th day of September, A. D. 1904, in thepresence of the subscribing Witnesses.
JOHNSON HUGHES.
