To all'who'm it may concern: I Be it known that I, PETRUS Hlinnnx, a I subject of the King of Sweden, and resident of Centralpalatset, Stockholm, Sweden, have invented a certain new and useful Improved Method and Means for Feeding the Trucks in Channel-Furnaces, of which the following is a specification. 7
The present invention relates to method furnaces.
On the accompanying-drawings the invention is represented, as an example only and diagrammatically, as being applied to a furnace for continuous charring divided into compartments by doors or dampers.
Figure l is a longitudinal section of the entrance end of furnace, F ig'. 2 is a'longitudinal section through the center part or the charring part of the furnace and Fig. 3 is a cross section on A-B of Fig. 1. Fig. 4 represents a longitudinal section ofa portion of the furnace in the vicinity of a door The furnace is divided into three compartcompartment 1, a charring compartment 9 and an extinguishing compartment 3, being, besides, built in a known manner and therefore need not be more fully described except the details which'are the object of my invention.
Along the floor of the furnace there is rovided a common track which, however, is interrupted at the dampers or doors 4 in order that the latter should be capable to completely shut off the compartments of the furnace from each other. The trucks 5 are built after the fashion of common rail road trucks having wheels 6 running on the rails 7.
- The means for feeding the trucks consist rack 8, preferably a so called ladderlike rack, fixed along the center of the underside of the bottom of the truck in such a manner as to lie directly beneath the shafts of the wheels, there being provided at the entrance end of the furnace between the rails a toothed wheel 9 meshing with the rack. The said wheel 9- is mounted on a shaft 10 extending outside the wall of the furnace and capable of being rotated by means of a Windlass 11 or any other. device placed outside the furnace. On each. side of the doors 4 there is provided a similar wheel 12, 13 and the shafts of both said wheels extend through the wall of the furnace and are capable of being rotated in any suitable manner from the outsideof the furnace.
The wheels 12, 13 are provided'on each sideof the row of teeth with roller surfaces or cylindrical surfaces 14,, 15 on which the.
side bars of the ladderlike rack 8 are supported at the time when one pair of the wheels of the truck passes the. interruption 16 of the track at the door, see Fig. 2.
' To provide against every possible disturbance of the work when the wheels 6 pass over the interruptions 16 of the track the side bars of the rack 8 maybe provided with downward projecting parts or extensions 17 at the ends (Fig. 4 the bearing surface of said extensions lying lower than the bearing surface of the sidebars. Those extensions 17' run upon the roller surfaces 14 and 15 respectively in passing successively the toothed wheels 12 and 13. Therethe pair of. wheels 6 of thevtruclt passes the interruption 16 of the track. When the front pair of wheels of the truck passes the interruption 16 the front extensions 17 of the truck bear on the roller surfaces 14 (see Fig. t)'and when the rear pair of wheels of the truck passes the interruption the rear extensions 17 of the truck bear on the roller surfaces 15. In both cases the pairs vof wheels in question are lifted above the level of the tops of the rails and thus pass freely over the interruption 16 of the track and do not descend on the rails until the extensions in question have left the roller surfaces. I
The charring is effected in a known manner and therefore need not now be described. The feed ,of the trucks is effected by means of the respective Windlass rotatrack on the truck in front of the first mentioned truck pushingzit and all preceding trucks in the compartment forward. .By operating the toothed wheels properly the displacements of the trucks required during the course of the charring process may thus be made.
I'claimz- 1. A feeding device for-trucks in channel furnaces comprising a railway track, a
rack on each-truck forming a continuous rack when the trucks are placed end to end on the track, a rotatable wheel at the entrance end of the furnace, movable doors in the furnace, an interruption of the track at each door, a toothed wheel rotatable from the outside at each side of the interruption, cylindrical surfaces on each side of the teeth on said toothed wheels and side bars on the racks, substantially as and for-the purpose set forth.
2. A feeding device for trucks in channel furnaces comprising a railway track, a rack on each truck forming a continuous rack when the tricks are placed'end to end on the track, a rotatable wheel at the entrance end of the furnace, movable doors in the furnace, an interruption of the track at each door, a toothed Wheel rotatable from the outside at each side of the interruption,
cylindrical surfaces on each side of the teeth on said toothed wheels, side bars on the racks andtlownwardly projecting extensions (17) at the ends of each rack, substantially as and for the purpose set forth. In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
