Oct. 11, 1932. H HARRls 1,882,580 v HEAT TREATING RECEPTACLE Filed Dec. 15. 1950 IN ENTOR ATTORNEYS embodying t e invention shown in the ac- 3companying drawing, wherein Fatented 11,
UNITED STATES [PAT T- OFFICE m! EIHABBIB, 01' DETROIT, MICHIGAN Application mm D ecember 1s, 1930. 8erla1 10.50am.
My invention relates to metallic receptacles such as carburizingboxes and the like. By my invention, I construct a sectional receptacle comprising one or more parts of rolled, forged or pressed metal, as rolled sheet metal, for example, united by welding,
. with parts of cast metal, so arranged and united that the more flexible sheet portion or'portions absorb unequal strains in five-L 1 sided containers to reduce deformation and failures in service. The preferred arrangement 1 s-one of alternation, as for example, cast pieces between sheet portions, and vice versa. a Objects ofthe invention include production of mechanically strong boxes, with imacity for resisting or absorbentto foundry practice and lightening of and provement in 'ca ing strains inci to heating and cooling inuse,
My invention will be best understood from description of constructions ective view of a metal- :lic receptacle consisting of east end portions with a member of rolled, pressed, or forged a (sheet) material welded intothe sides an .Figure'l is a persp 1.34 bottom of the boir between the east end portions to connect the same. Fig. 2 is an inverted perspective view of a metallic receptacle with asheet member welded into the ends and bottom thereof to connect cast side portions;
'Fig. 3 is an em ed sectional detail view;
taken 'on line 3-3 0 Fig. 1; f 7
- Fig. 4 is a rspective view'. of a metallic.
ediate portion of sheet metal, the latter 0on itflting portion of the box walls; Fig "1's a viwsimilar to Fig. 4 in which part is of cast metal;
7 12, 12, and a connecting web ;V-shaped grooves G bein receptacle .--re'ceptacle similar'to that of Fi 1 having d portions of cast metal' Wi inter" rtionst-iare stamped sheets and the j also, if desired, the corrugation or beading enerally, which comprises two end ortions 5 or the ike, and oined together b a strip of rolled, for S of substantially t edges thereof along strip S being preliminarily formed up into substantially U-shape to fitbetween the end members C C and comprising side legs rtion 14'. This strip S of sheet metal or t e like serves to take up the unequal strain resulting from high temperatures, and by forming a central corrugation or shallow beading portion 16 therem, a reinforcement is provided in addi- 1 tion to that produced by the welds. Electrical welding is preferable, substantially formed between ed with welding 2 the sideportion's C G, of the. 10a are cast, and a" strip of rolled, forged, or pressed material S, is welded at W' to the meeting edges of said portions along .the welding grooves to join same. shallow beading orcorrugat'ion 16a ispreferably also provided for reinforcement.
In these two forms, the cast portions make 4 up the main part of the box.
- In Fig. 4 I-- have shown relatively shallow cast end portions 0 C, with an inter d broad sheet metal portion S welded t erereferably cast of 'chromenic el alloy welding v d, or prese material e same analysis, to the the arts to be united and d stic material 18.
In Fig.
' between and making up ,the main part of the 'box'. Sheet part S ma be corrugated, or
beaded,'if desired, to give added strength cast all in one piece.
Figs. 1 and may be dispensed with, as in Fig. 4.
The form of Fig. 5 islsimilar' to Fig. 4,.
but resembles Figs. 1 and 2m that the intermediate broad cast portion C, forms the main part of the box and is interposed by welding between relatively shallow sheet metal end portionsS S,;, which may convientlybe stamped or forged into shape.
The form shown in Fig. 6 comprises a cast body G. having corners S, of preformed forged, rolled or stamped material welded into ooves dr while in the form shown in Fig. a sheet body S has cast corners C welded in place in groovesG as indicated at W The corner pieces'preferably fill out a corner recess in the box bottom and also include a preferably fillet form upright portion that is interposed between the edges of the end wall and side wall box parts.
v .In my invention, the receptacle being made of sections, such sections or ortions can be of reduced weight compare to the weight of the corresponding rts of a receptacle y the use of sections composed in part of sheet material and in part cast, strains from the cast portion or portions are transmitted to and absorbed by the flexmg sheet portion or portions, the
structure thus formed being stifier and stronger than one entirely composed of sheet material but more flexible than one which is entirely cast. My invention is particularl adapted for five sided containers in whic the bottom expands (or contracts) at a greater rate than the open portion of the container, this being liable to cause distortion and failure of the rece tacle if entirely cast.
It will be understoo that when boxes such as shown are used in push furnaces they are inserted and the pushin forces are applied through the trays (not s own) forming th sixth side ofthe receptacle. 1
' The term sheet is used in the-claims as a".
convenient designation for metal that is pressed, for ed, or rolled. Having escribed my invention, I claim: 1. A metallic receptacle for use in heat treatingl furnaces comprising a luralit of at the contiguous edges thereof, each of said members including artial bottom and vertical wall portions, e depth of each vertical wall portion being equal to the depth of the receptacle, and said members being in part of sheet metal and in part cast.
3. A metallic receptacle-for use in heat treating furnaces comprising integrally formed outer and intermediate members complementing each other to form the vertical and bottom walls of the receptacle and welded together at the contiguous edges thereof, each outer member including one vertical wall of the receptacle and portions of the other vertical walland bottom wall of the receptacle, and the intermediate member including-the remaining portions of the bottom and verticalwalls of the receptacle, said members being composed in part of sheet metal and in part cast.
4. Receptacle as claimed in claim 3 in which the verticalwall portions of the intermediate member comprise the main parts of the side walls.
5. Receptacle as claimed in claim 3 in which the partial wall portions of the outer members comprise the main parts of the side walls. 1 I
6. Receptacle as claimed in claim 3, in which the intermediate member is of sheet metal and the outer members cast.
7 A rece tacle as claimed in claim 3 in which the 1ntermediate member is of cast metaland the outer members of sheet metal. 8. A receptacle as claimed in claim 3 in which the outer members are cast and the intermediate member comprises a relatively narrow strip of corrugated sheet metal.
9. A metallic-receptacle for use in heat treating furnaces comprising acast body portion-complete exce t at corners, and sheet metal corner mem rs having vertical and bottom wall portions received into the corners tocomplete the body portion and welded in the corner .places. 10. A metallic'receptacle treating furnaces comprising a sheet body portion complete'except at t e ast corner members having vertical and bottom wall portions received into the corners to complete the body portion and'welded in the corner laces.
for use in heat corners, and
. 11. ic receptacle for use in heat 1 5 treating furnaces comprising a plurality of integra y formed members each including partlal bottom and vertical wall portions, said members complementing each other to form the vertical and bottom walls of the re-" ceptacle and bein welded together at the contiguous edges t ereof.
12'. A'metallic receptacle for usein heat treating furnaces comprising integrally formed outer and intermediate members complementing each other to form the vertical and bottom walls of the receptacle and welded together at the contiguous edges thereof, each outer member including one vertical wall of the receptacle and angularly' disposed portions of the other vertical walls and bottom wall of the receptacle, and other of said members including the remainin portions of the bottom and vertical walls 0 the receptacle. 4
13. Receptacle as claimed in claim 12 in which at least the outer members are of cast metal.
14. A metallic receptacle for use in heat treating furnaces comprising sheet portions and cast ortions so meeting as to provide substantia ly V-shaped grooves, and metal substantially filling said groovesand securin the parts together.
in testimony whereof, I have signed my name hereto.
