Originalapplication filed June 19, 1912, Serial No. 704,495. Divided and this application filed May 13, 1913; Seria1NoQ76'L268.
) To all-whom it may concern:
Be it known that I, HERMAN Hrnnn BRAND, J12, a citizen of Germany, residing at WVerdohl, in Westphalia, Germany, have 5 invented a new and useful Annealingllpparatus, of which the following is a spccili: cation. I This invention relates to anovel apparatus for annealing metal articles in a quick, reliable and effective manner.
This application is a division of a co penchng'patent application for'a'n' annealing apparatus, filed by the June 19th, 1912, 1111- der Serial No. 704,495. 0
In the accompanying drawing: Figure 1 is a: vertical section on line 11, Fig. 2, through an annealing apparatus embodying Jm-y invention; Fig. 2 a horizontal section through the cooling chambers; Fig. 3 a detail section of the piston and of part of the vessel supported thereby, and Fig. 4 a similar section taken at right angles to Fig. 3. My improved annealing furnace consists essentially of a cooling chamber 95, the .ingross and egress openings of which are adapted to be respectively closed against the able pistons 32 and 33. The flange of pis ton 32' is made to normally bear against a packing ring in a groove 96. The piston 32 can be moved up and down by means of a rack 97 and'a pinion 98 meshing therei w t C d tube 99 on the casing 95--s='-=== rounding the rack 97 for preventing the light neutral gas that fills casing 95 from escaping. A -carriage 100 adapted to supportja box'or container 3 1 open atthe top 'andfclosed at the bottom is provided with i nea ns for raising the box 3 1 through a short height and pressing its upper flange 112 against the corresponding flange 113 of the casing 95. The said raising means are shown'to consist of two parallel triangular standards 114 located at both sides of the box 34:, two handles 115 pivoted at the up- 36irigidly connected withthe handles. The eccentrics are adapted to bear from below against two opposite lugs 116 on the box for moving the latter upward. A screw-spindle 101 passes through a stuffing-box in the bottom of the box 34 and can be turned by means of a hand-wheel 35 for moving up and down asupporting disk 102.f A fresh charge, for example a column of superposed I :latmosphere by a pair of independently -mov-' vessels '2? charged with the wares and connected with aheadplate or charge carrier 28 by means of a cross pin 38, is introducediuto the box 3t and placed on the supporting disk 102. After-wheeling the charged carriage 100 near to the piston 32, the handwhee 35 is so adjusted as to raise rollers 29 which are pivoted to head-plate 28 above the level of a rail 31 depending from piston 32. Then the carriage 100 is turther pushed sidewise until all the rollers 29, 29 are joint between the box 34; and the casing 95 and by means of suitable valves (not shown) provided on the box 34, the air is expel-led from the box and replaced by a neutral gas, whereupon the pinion 98' is operated for raising the piston 32 with the depending charge into the casing 95.-
By suitable push rods 117 extending through stuth-ng bones 118 into casing 95, the rollers 29, 29 of the headplate 28 are "shifted from the rail 31 of the piston 32 to the overhead rail 30* of the cooling chamber l 95, whereupon the piston 32 is again lowered to shut oil casing 95 from the atmosphere and the box 34 is lowered and moved away inserting the charge into the annealing pot 106 which is received within an annealing oven and shutting off the pot from the cool ing chamber. After the annealing operation has been completed, the piston 103 is again raised and the annealed charge is shifted to'the other part of the rail 30 within cooling chamber 95, while a fresh charge 18 moved beneath piston. 103. The annealed charge is allowed to cool off in chamber The short tube 37 depending from the casing 95 at its right end, is recessed at its upper end for the reception of a packlng ring, against which the piston 33 is made to normally bear. The piston 33 is rigidly Pater; ted Sept. id, 1913. I
connected with a tube 107, in whicha rod 108 is longitudinally guided. This rod car ries at its lowerend a rail 109, and may be moved up and down from Without by being formed as a rack that is engaged by a pinion 108 The tube 107 is provided with a rack 110, which meshes with a pinion 111, whereby the piston 38 may be moved up and down. It is obvious, that when both the piston 33 and the rail 109 occupy their highest position, the cooled annealed charge .can be shifted from the rail 30 to the rail 109, after which first the piston 33 islowered to shut ofi? the cooling chamber, whereupon the charge is, by means of the rod 108, lowered through the tube 87 and is then taken ofi I claim:
1. An annealing furnace provided with a cooling chamber having an ingress opening, a piston adapted to close said opening, a charge sustaining support depending from the piston, a container, means for raising the container into contact with the cooling chamber around the ingress opening, a charge carrier within the container, and means for elevating said carrier into engagement with the charge sustaining support.
2. Anannealin furnace provided with'a cooling chamberfii communicating With the chamber intermediate said openings, a piston adapted to close aving an ingress opening and an egress opening, an, annealing pot ton, means for suspending the charge With- 7 in thecoolmg chamber, means for conveymg the charge from the cooling chamber into and out of the annealing pot, and means movable independently of the second named piston for delivering the charge from the egress opening. a p 3. An annealing furnace provlded with an lngressopenmg and an egress opening,
a piston adapted to close the ingress openmg, a second piston adapted to close the egress openmg, said second piston being provided with an upwardly extending tube,
an independentlymovable rod encompassed depending from said rod.
4:- An annealing furnace provided wlth a cooling chamber havmg an lngress openmg and an egress opening, an annealing pot communicatlng with said chamber mtermediate said openings, a first piston adapted '50. by the tube, and a charge sustaining support to close the ingress opening, a second piston adapted to close the mouth of the annealing.
pot, a third piston adaptechto close the egress opening, charge sustaining supports on the first and second named p1stons,"overhead charge sustalnlng supports .wlthln the cooling chamber, a tube extending upwardly from the third named piston, an independently movable rod encompassed by'said tube,
and a charge sustaining support depending from said rod.
