- Application filed August 8, 921. serialiit; 490,678:
'fo'llowingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap'pertains'to make and use the same. My invention relates to metal Hanging machines and has for its object to provide a simple and efficie'nt niachin'efor forming a continuous flange on a sheet of metal means of a die and rollers co-a'cting therewith, novel provision being made for con stantly forcing the die toward a flange on one of the rollers which turns the flange on thesheet of metal around the edge of the die, the" machine being intended principally for constructing can-box ends for truck tanks. 1
With the foregoing in view, the invention resides in-the novel subject matter here in described and claimed, the descriptive matter being supplemented by the accompanying drawings.
Figure 1 is a side elevation, partly in vertical section, showing a Hangingniachine construction in accordance with my invention.
Figure 2 is an enlarged vertical section, partly in elevation, showing more particularly the flanging rollers, the die, and the springpressed shoe for holding said die in operative relation with the rollers.
Figure 3 is a plan view showing one shape of the die and illustrating the manner of securing a sheet of metal thereto.
Figure 4 is a sectional view as indicated by line 4 4 of Fig. 3.
Figure 5 is a sectional view of a sheet of metal flanged by the machine.
In the drawings above briefly described, the numeral 1 designates a horizontally elongated base from one end of which a casting or other suitable roller support rises, said support being preferably provided with an overhanging arm 3 whose free end carries a vertical guide way 4 in which a bearing box 5 is vertically movable by means of a suitable screw or the like 6. A shaft section 7 is rotatably mounted in the box 5 and is provided at one end with a flanging roller 8' whose inner edge is inner end of the shaft section 2 by-a universal joint 10 with extensibie' and contractibl'e shaftsectio'n 11 which is iii turn universally connected at 12 to a shaft is connected Specification ofiettersf atent. p fit d A g] 5' V equipped with a peripheral flange 9. -The section 1 8 which extends through the arm 3,
1 end of the shaft section 13 is provided with a gear 14: meshingwith another gear 15' on approximately its juncture with the ower portion of the support '2. The outer a horizontal shaft 16 which eiitends througliy I the support '2, below the arm 3 and, carries stationary roller 17' disposed beneath the roller 8.= The shaft 16' is providectwi'th suitable driving means such" as tight and loose pulleysl'd co-operable with a belt 1 9. i
V'Vhile certain" specific details havebe'en shown for mounting the roller 8 so that it.
may be moved vertically, arid for driving both of the rollers Sand 17 I wish it under stood that any equivalent means could be I provided and furthermore that the machine 2 would operate in some instances if, only one of the rollers were driven.
' The end of the'bas'e l i"em'ote from the roller support 2, 18 provided with than propriate die supporting meningwhih i here shown in the form of upstanding flanges 20 extending across the base. I Here again, however, a is to be understood that the die support be o'fl-any adequate construction. i 1 One form of die is shown in the drawings, being designated by the reference numeral 21, this die being in'the form of a continuous bar forming an open'franie. The shape of die shown is intendedfo'r forming flanges on sheets of metal 22 for use as can-boX ends for truck tanks, but it will be understood that any shape of die may be used. The sheet 22 is secured upon the die 21 by any suitable means, such as a pair of screws 23 and with the roller 8 in a raised position, the die and sheet are then placed upon the supports 20 and roller 17. The roller 8 is then lowered and its flange 9 bends the first por-.
pressed shoe 24lengaging the inner edge of the die 21 as shown clearly in Figs. 1 and 2. This shoe is preferably in the form of a 'roller, mounted, on one end of a horizontal lunger rod 25 which is slidably supported ldy a pair of standards 26 rising from the base 1. The rod 25 as here shown, is pro vided with a collar 27 and a coiled spring 28 is interposed between this collar and one of the standards 26. The collar 27 is by preference threaded upon the rod 25 so that the strength of the spring 28 may be controlled to insure that the shoe 24 shall at all times exert the necessary pressure on the die.
A machine constructed as or approximately as herein disclosed, will form a continuous flange on a metal sheet with much greater speed than the usual hand methods I now employed and furthermore, a much smoother and better job is produced.
Since excellent results may be obtained by r using the details shown, they may be followed if desired, but as above stated, numerous changes may be made and the present disclosure is therefore to be considered for illustrative purposes only.
I claim:
1. A flanging machine comprising a pair of spaced rollers and driving means for at least one of said rollers, means mounting said rollers with their axes in parallel relation, one of said rollers having a circumferential flange, a sheet-carrying die adapted to travel between said rollers, and means for forcing said die continually toward the flange of said one roller.
2. A flanging machine comprising a pair of spaced rollers and driving means for at least one of said rollers, means mounting said rollers with their axes in parallel relation, one of said rollers having a circum- :l'erential flange, a sheet-carrying die adapted to travel between said rollers, a springpressed member mounted for movement toward said rollers in a direction parallel with their axes, and a shoe carried by said member for forcing said die continually toward the flange of said one roller.
3. A Hanging machine comprising a pair of spaced rollers and driving means for at leastone of said rollers, means mounting said rollers with their axes in parallel relation, one of said rollers having a circumferential flange, a sheet-carrying die adapted to travel between said rollers, said die being continuous and in the form of an open frame of slightly less size than the sheet to be flanged, and means for supporting the frame and sheet while leaving them free to move under the action of the rollers.
l. A flanging machine comprising a base having an upwardly extending roller-supporting structure, a stationary roller mount ed on said structure on a horizontal aXis, a vertically movable flanged roller mounted on said structure above said stationary roller, means mounted on said structure for raising and lowering said upper roller, means for driving at least one of said rollers, die sup-- porting means rising from said base, an open die forming frame adapted to be horizontally supported on said die supporting means and said stationary roller, said frame being adapted to carry the sheet to be flanged, a spring-pressed shoe for forcing said frame toward the flange of said vertically movable roller, and means mounting said shoe on said base.
In testimony whereof I have hereunto set my hand.
HENRY R. BREMER.
