To all whom it may concern: 1
Be it known that T, CARL M. Yonnn, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful improvements in Devices Used in Bending Metal, of which I hereby declare the-following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. 7
The invention relates to metal bending apparatus, more especially an apparatus of the type capable of bending'a section, band or strip of sheet metal edgewise or in its own plane. The present invention particularly relates to the means which support the band or stripand prevent it orportions thereof from twisting, bending, springing or becoming distorted While the strip is being bent.
This application is a division of my ap plication Ser. No. 597,769,1iledDece1nber 17, 1910. i
The object of the invention is to provide improved means for supporting'and holding the section, band or strip of sheet metal while being bent.-
Withthis and other objects in view, the invention consists of the parts or combinations ofpartshereinafter described and referred to in the appendedclaims.
For the purpose ,oflillustration 1 have, in the accompanying drawings, shown and herein describedv one form of apparatus embodying my invention.
Figure: 1 is a plan view of ametal bending apparatus having band supporting and holding meansembodying my invent on.
Fig.2 is a fragmentary perspective view, enlarged, of the band support and holding means. y i s Fig. 3 isa transverse sectional view of the parts showninFig-Q.
In these figures,A is the metal band shown as the mud rim ;of an automobile wheel which may be providedlwith f reinfender forcing marg nal wires.
This band extremelyv tobend edgewise'or in its own plane, owing to the a tendency of the flat bandto flex, spring,
buckleand bend in all directions relativeto the plane in which the band is disposed. To I prevent flexure in any direction the clamping or holding members B, Bf. are applied to theoppositefaces of the band, they being preferably clamped together and against the lanl by means of a series of spaced clamps a Each clamping or holding member comprises a series of relatively thin parallel flexible metal plates 6, b engaging on their edges the adjacent face of the metal band. These plates 6, b, are rigid in the direction of their edges, but preferably extremely flexible at i right angles thereto.
The bolts 1) and Washers in additionto their connecting and spacing functions,,
serve to strengthen the plates Z) between their upper and lower edges,with0ut affecting the fiexibilitythereof. l a i c The bolts I) pass through elongated slots 6 5 in the plates, thus permitting the plates to bendin either direction in unison with the metal band A, butwill absolutely prevent flexing or bending of the metal band in any direction except edgewise. Each clamp C comprises a standard, the base portions 0, O of which rest on the table T of, the bending machine and extend in opposite directions from the band to prevent the clamp from turning while the band is being bent. vThe,clampingmember 13" preferably rests on the-baseportions C of the clamps and supports the band A on its upper surface, while the clamping member B rests on theband A so that the clamping members, when clamped together, will securely hold the band A between them. The clamping device of each clamp G preferably comprises a plate C arranged to engage the upper clamp member 13, as shownin Fig. 3,
and a cam lever G which engages with and forces the plate C downwardly against the clamp member B. The lever C is pivoted at C -on the standard and is provided with a handle, whereby it may be operatedto clamp and unclamp the plate (3 ,1 a, it p In Fig. 1 curved formers T T are shown mounted upon a flattable Tq The face of;
the former is preferably provided with a groove T to receive the reinforced edge of the band. The formers T."are preferably supported above the table T to permit the base portions C of the standards to slide 'therebelow, as shown in Fig. 8. Byrthis-construction the lower surface of the former T and-the upper face of the table T cotiperate to prevent turning or up-setting of the standard.
When it is desired to bend a band A, it is first positioned and clamped between the clamping members B, B; one end of the band is then fixed to a suitable support while that endwhich is to be bent secured to a movable member, such as the carrier E which may be mounted on a track F. The carrier is then moved laterally carrying with itthe band'A'. to bend it around the former T, as shown in Fig. 1. When both ends of the bands are to be bent, then two movable carriers-E are provided, the opposite ends of the band being secured to the carriers which may be-moved separately or simultaneouslyas desired.
To those skilled in the art of-making apparatusof the class described,- many alteraparallel to the plane of the metal section and engaging one side of and movable with said metal sectionduring bending thereof, a" similar member engaging the other side of and movablewith said metal section during bending thereof, and a series of spaced clamping devices movable with said members and arranged to clamp them against the opposite faces-of the metal section.
2. A device for bending a section of metal comprising aseries of flexible metal plates extending longitudinally of the metal' section with'corresponding longitudinal edges engaging oneflat side thereof, a similar se ries" of flexible metal plates having their longitudinal'edges engaging the other side of themetal section, means for slidably attachingthe plates of each series together, and means for clamping each-said series of plates againstthe adjacent side of the metal section.
"35 A device for bending a section ofmetal comprising .a member engaging each side of the metal section, each said member com prising a series of slidably connected t0- gether plates havin their edges engaging the adjacent side of the metal section, a series of clamps, and means acting on said clamps to press said members against the opposite sides of the section.
4. In apparatus for bending a section of metal, the combination of a series of parallel plates having their edges engaging one side of the metal section, a similar series of metal plates having their edges engaging the other side of said metal section, said plates being provided with longitudinal slots, connectors passin through said slots, spacers upon said connectors, and means for securely clamping said series of plates upon said metal section.
