Specification of Letters Patent.
Patented Sept. 15, 1908.
Appfieation filed April 14, 1908. Serial No. 427,073.
' To all whom it may concern:
Be it known that I, Enwm Noerou, a citizen of the United States, residing at Lake Placid, in the county of Essex and State of New York, have invented or discovered new and useful Im roveinents in Air Conveyors, of which the to lowing is a specification.
My invention relates to that class of conveyers which employs a blastof air for moving articles along a track or runway, and particularly to the employment of such rreans of conveying heated,flwide, thin sheets or packs I of steel from a train of rolls, such, for examle, as ?.S shown in Letters Patent of the lnited States, No. 865,055, granted tome on the 3rd day of'S'eptember, 1907.
When a continuous train of rolls'is used for reducing a sheet-or pack which not only reduces the metal by a succession of passes, but
also stretches the metal between the succesthe desired lengths, it is necessary that the packs or sheets be quickly and uniformly cooled before passing to the shears in order that they may have the buckle removed and the surface restored to the fiat smooth condition it was in .on leaving the rolls. To that end, Icombine with the storage chamber of the air conveyor, a suitable means for refrigeration or artificially reducing the temperature of the air within the chamber of the conveyer to its lowest possible point before discharging it against the sheets or packs of heated metal to convey it from the mills to the shear table.
As th" sheets or packs of metal follow each other in rapid succession from the rolls, it will be seen that, when the air of the conveyer is artificially cooled, I am able to greatly increase the capacity of the mill because the sheets will be at once delivered to the shears smooth and in proper condition to be sheared; and by maintaining a refrigeratcd air pressure with n the conveyor, the resluts wil be uniform rcganlless of the tempcrature of the mill, which is subject to wide variations in hot and cold weather. The quality of the surface of the sheets or latcs is, by my invention, greatly improve" and the quantity that can be turned out in agiven time is greatly increased by. the simple means described.
To enable others skilled in the art to make accompanying sheet of drawings, in which- Figure 1 is a plan thereof with portions brokenaway; Fig. 2, a side elevation. thereof;
and Fig. 4, a section of Fig on the line 4-4.
On the drawings, 1 represents a casing, containing a fan 2 which drives air throu h an air chamber, having preferably t e straight section 3, the elbow section 4, connected to the section 3, and the straight sec tion 5 connected to the outer end of the elbow section 4, the sections 3 and 5 being sections 3 and 4 may rave their top surfaces shaped as desired, but the section 5 has its upper surface trough-shaped. Preferably the section 5 is com sed of two walls, the outer Wall 6 being s'u stantially a semi-circle in cross-section and the inner or top wall 7 bein an arc of a large circle which joins the opposite sides of the wall 6 at or near its upper edges. The wall 7 has its concave bus slits or holes 8 inclined from the interior the air chamber toward the outer end thereof.
Several stands of rolls 9, such as hereinbefore mentioned, are arranged in line with deliver rolled sheets or packs into the trough-like runway 10 formed by the said walls 6 and 7 aforesaid.
It will be readily seen that the fan will cause streams of air to issue from the inclined holes 8, whereby a sheet, such as 11, will be carried or partially floated along the desired machinein which the sheet is toreeeive further treatment, such as shearing, as already stated.
' In order to cool the sheets or packs for the urposes aid to the degree described herein, have shown in the section 3 a coil 12 of pipes and in the section 5 another coil 13 of pipes, designed to carry a. refrigerating agent, i as ammonia. These pipes may be arranged and use my invention, reference is bad to the Fig. 3, a section of Fig. 1 on the line 3-3;'
