EUGENE l1 BRO'W'A JR,
BOD--BENDING APPARATU S.
Application filed June 19,
To all whom it may concern:
Be it known that I, EUGENE'L. BROWN, Jr., a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Rod-Bending Apparatuses, of which the following is a furl], clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to an apparatus for bending rods or the like, and is more particularly adapted for use in bending reinforcing rods used in concrete structures.
Figure I is a plan or top view of a bending apparatus constructed in accordance with this invention. Fig. II a section In the accompanying drawings: A designates' a portion of a rod disposed in the bending apparatus so as to bend at a and 7) while the bending members are moving from the position shown in full lines in Fi i I to the position shown in dotted lines. The
' rod Ais placed betweerra pair of jaws 1. and
2 secured to a stationary member 3, the jaw 1 being adjustable.' The jaws 1 and con+ stitute a stationary holder and are parallel to a movable holder, comprising jaws A and 5 carried by a link-arm, or carrier, 0, the jaw 1 being adjustable. Rods 7 and 8 pivoted to the stationary member 3 are provided with collars 9 and 10, respectively, to which the link arm 6 ispivotally connected. The pivotal rods 7 and 8' are also joined by a link 11. Fixed to the rod 7 near the poin t- 6, is an abutment 12 that engages the rod A and causes it to bend between said abutment and the nose 1' of jaw 1 during the operation of the apparatus, and the collar 9' is provided with an abutment 12 for causing the rod A to bend between said abutment and the nose 4 of the jaw 4:, which theparts are moving to the position shown in dotted lines. The abutments 12 and 12 hold the and A parallel to the pivotal rod 7 and serve PATENT canoe.

1911. Serial No. canoes.
the rod holding jaws a: and 5 to remail'ic'ons stantly parallel to the other jaws when the first named are moving in an ai'cuate p1,, during the bending operation. The b'en article produced by this apparatus has spans allel portions c and (Z connected by anvinr clined portion 6, and is'thcrefore properly shaped to form a well known type ofrei-Iiforcing rod for concrete structures. The sleeves 9 and 10 are preferablv secured to the pivotal rods by set screws 17 to ward and away from the stationary holder, thereby making it possible to vary the distance between points at which the rod operated upon is bent.
transversely and longitudinally of the apparatus to pernnt of the holders being set to grlp rods of diil erent (1121 meters and to propbends. The transverse adjustment of said aws is accomplished by usting screws 18, and the longitudinal adjustment by adjusting screws 19, said screws being operable in L-shape brackets 3"and 6 carried respectively by the support 3 and link arm 6.

enable the movable holder to be adjusted to- The jaws 1 and'l are' adjustable both erly present the noses 1 and 4 to the abutments 12 and'12' to produce the desiredsaid holders may he moved in an arcuate path and kept parallel with the other holder during its movement; the said movable means comprising a pair of parallel pivotal rods, members adjustably mounted on said rods and a carrier for said movable holder pivoted to said adjustable members. I
5. A bend ng apparatus comprising two holders for the reception-of the article to. be
bent, and movable means by which one of said holders may be moved in an arcuate path and kept parallel with the other holder during its movement; the said movable means comprising a pair of parallel pivotal rods, a carrier pivoted to said rods by which .the movable:- older is carried, and an abutment associated with one of said rods ad- ]acent to said movable holder.
6. A bending apparatus comprising two holders for the reception of thearticle to be' bent, and movable means by which one of:
said holders may be moved in an arcuate path and kept parallel with the other holder duringits movement; the said movable means comprising a pair of parallel pivotal rods, a carrier pivoted to said rods by which the movable holder is carried, and abut ments carried by one of said rods and located adjacent to said holders.
' 7 A bending apparatus comprising a 'stationary member, a holder for the reception oft-he article to be bent supported by said stationary member, a. second. holder, and
movab e means by which said second holder morass said stationary member, a second holder,
and movable meansby which said second holder may be moved in an arcuate path and kept parallel-with the first mentioned holder; said movable means being provided with abutments located adjacent to said holders.
9.2; bending apparatus, comprising, a I
stationary member, a holder for the .refc'e'p tion of the article to be bent supported by said stationary member, the saidijholder being provided with a nose, ancarr'iena second holder on said carrier, means-pivoted to said stationary member by which said carrier is carried and through the medium of WlllCll tlh) second holder is kept parallel:
with't he first holder during the mriyement of said movable means in an arc of a'I"'circle, the second named holder being provided with a nose, and abutments carried by said movable means adjacent to said holders between which and the noses of the holders the article operated upon is bent. a EUGENE L.
