Specification of Letters Patent.
Patented Jan. 11, 1921.
Application inea umh 5, 1920. serial No. 363,538.
To all whom 'it may concern:
Be it known that I, O'r'ro BARR, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Im rovements in Sheet-Metal-Tube-- Forming achines, of which the following is a specification.
The main objects of this invention are to provide an' improved machine for making sheet-metal tubing; to provide a machine having improved means for forming the tubing from two sheets of metal; to provide improved means for properly spacing apart the sheets of metal from which the tube is formed whereby said tube will be of the desired cross section; to provide improved means for corrugating the tube transversely .of its length as it is formed; and to pro- -in the background being omitted.
Fig. 4 is a similar view takenon theline .4-4 of Fig. 2.
Fig. 5 is an enlarged fragmentary detail of the intertting parts of the rolls.
Fig. 6 is an enlarged sectional detail of a form of sheet-metal tubing which the particular modification herein shown is de' signed to produce.
Although this invention is not limited to that particular i purpose, the modification herein illustrated and described has been designed for use in the formation of tubing of the type shown in my copending appllcation Serial No. 329,394, filed Oct. 8, 1919,
,which tubing is to be used particularly for the manufacture of radiators for cooling the circulating water used in connectlon with internal combustion engines and the like.
In the specific embodiment herein dia-` grammatically illustrated, the device comprises a pairjof rolls 7 land Sand a. core member or mandrel 9 arranged to form two strips of metal 10 and 11 into a sheet-metal tube 12.
The rolls 7 and 8 have their peripheres shaped toprovide axially disposed corrugations 13 and are mounted on shafts 14 and 15 sc as to be rotated at uniform speeds by sultable gearin (not shown). The' mounting of the sha s 14 and 15 is such that the peripheries of said rolls are properly spaced rapart to coact with the core member or mandrel 9 in the shaping of the strips of metal 10 and 11 to a tube 12 of the desired cross section. Grooves 16 and 17 are circumferentially formed in theI periphery of the lrolls 7 and 8 respectively nearthe'ends thereof, which grooves are adapted to coact to form the seams in a tube, as will more fully hereinafter appear. n
The core member or mandrel 9 is of a fiexible nature being constructed from heavy woven cotton canvas, woven metal fabric or a combination of the two. As herein shown, a
strip of the flexible material is looped through a slot 18 formed in a' plate 19 ex tending rearwardly from the rolls 7 and 8 and secured to a block or bar 20 mounted on the frame of the machine. The width and the thickness of the flexible material is made so as to give the desired shape to the tube 12. The stri s of sheet- metal 10 and 11 are cut and shape by other means before being fed to the rlls 7 and 8. In this particular case, the sheet 10 has had the edges thereof curled around reinforcing wires 21 and then bent to provide fianges 22. The strip 11 has its ed es turned so as to provide the flanges 23. uitable means are provided for feeding the sheets 10 and 11 to the rolls 7 and 8 in such a way that as said strips approach the rolls, the flanges 22 pass into engagef yment with the flanges 23 inwardly thereof.
The operation of the machine as herein illustrated, is substantially as follows: p
By suitable mechanism, the strips of metal 10 and 11, previously shaped, are fed to the rolls 7 and V8. As said strips approach the rolls, the pairs of flanges 22 and 23 enter into engagement as has just been explained, and upon entering the grooves 16 and 17 of the rolls 7 and 8, are bent over and firmly compressed togetherv to form a substantially water-tight seam along the edges of the tube. As thestrips pass between the rolls 7l and. 8 and are seemed together, they are given aA corrugated formation, asshown to merous details of the construction shown maybe altered or omitted without departing from the spirit of this invention' as defined by the following claims.
I claim:
l. In a machine for forming flat tubing,-
the combination of a pair of opposed rolls having their perpheries spaced apart and a stationary liexible core member arranged between said rolls, said rolls being adapted to have fed between them on 0 posite sides of said core member strips o metal having llanges formed along theedges thereof, said rolls having their peripheries shaped so as to coact with said c'ore member and with each other to form said strips into a tube of elongated cross section wlth said flanges compressed into seams along the edges of said tube.
2. In a machine of the class described, the combination of a pair of rolls having their peripheries specially shaped and spaced apart and a stationary flexible core member arranged between said rolls, said rolls and core member coacting to form a sheet-metal tube of predetermined shape and cross section.
8. In a machine of the class described, the combination of a pair of opposed rolls having their perpheries spaced apart and providedwith axially disposed corrugations, a stationary flexible core member arranged between ysaid rolls, said rolls being adapted to have fed between them on opposite sides 'of said core member sheet-metal strips, said rolls .and core member coacting to form said sheets into a corrugated sheet-metal tube of predetermined cross section.
tube properly l spaced y 4.' In a machine for forming at corrugatedl tubing, the combination of a pair of rolls having the eripheries thereof spaced apart and provi ed with axially disposed corruations, to which rolls are adapted to be fe strips of metal having flan es formed along the edges thereof, said ro s having theirA peripheries constructed circumferentlally so as to coact with said corrugations of the redetermined cross section and to form said flanges into seams.
f in shaping said strips into a corrugated tube y In amachine of the class described lthe combination of a pair of opposed-rolls havl ingtheir. peripheries speclally shaped and spaced apart, a canvas core member arranged4 between said rolls, a support arranged 'at one side of said rolls in substantial alinement with the space between them and connected to said core member, said rolls being adapted to have fed thereto on o posite sides o said core member strips o? metal having flanges :formed along the edges thereof, said' rolls and core member coacting to form said sheet into a sheet metal tube of predetermined shape and cross-section, with said -ianges compressed into seams along the edges thereof.
6. In a machine of the class described the combination of a pair of-opposed rolls having their peripheries specially shaped and spaced apart, va` core member arranged between said rolls, a support located at one side of said rolls and a connection to said support from said core member adapted to maintain the core member in substantially fixed alinement with a space between said rolls, said connection being so mounted that the space on all sides thereof rearwardly of said rolls is substantially unobstructed, whereby said rolls are adapted to have fed thereto on opposite sides of said core sheets of metal of substantially unlimited lengths, said rolls and core coacting to form said sheets into-a sheet-metaltube of the desired shape and cross section.
