Roper Whitney No 412, 414, 416 4 foot bending brake Instruction Guides

No. 412, 414, 416 Operations Manual

CARE: Occasional oiling of moving parts with machine oil will ease operation and extend the life of the brake. Occasionally check and
tighten the lower beam bracket gib screws (see figure 1 ) at each end of the brake. These screws are accessible when the apron is raised.
These should be kept snug to reduce excess front to back play in the lower beam.

CAUTION: Do not form wire, nails, rods or pipe in these brakes. These brakes will form a 1" flange over the entire length in their rated
capacity.

Brakes are reduced in capacity by 2 gauges when:

1. Apron angle iron work support (see figure 2) is removed.

2. Box fingers are used,

Brakes are reduced in capacity by 4 gauges when:
1 . Apron angle iron work support and apron filler plate are removed.

2. Brake is used on stainless steel.

ADJUSTMENTS - BEFORE OPERATION

1. Apron must be flushed with lower beam jaw before beginning operation. To adjust loosen apron mounting bolts slightly and turn apron

adjusting screws as necessary. After adjustment, retighten apron mounting bolts. If alignment cannot be achieved, follow major brake
alignment procedure following.

CLAMPING PRESSURE ADJUSTMENT

2. Check gauge of material to be formed to be sure it is within rated capacity of your brake. Place small sample of work piece on Lower

Beam Jaw and clamp in position by moving the Clamping Lever forward. Sample should now be held firmly in position. To adjust for
more or less clamping pressure, move Clamping Lever to unlocked (up) position, loosen the Clamping Lever Turnbuckle Lock Nut
(figure 4) on both ends of brake and adjust the Clamping Lever Turnbuckles as necessary to achieve firm clamping pressure. Retighten
the lock-nuts.

THICKNESS OF MATERIAL ADJUSTMENT:

3. Loosen the Upper Beam Slide Clamping Screws (figure 5) and Upper Beam Adjusting Screw Lock Nuts at both ends of brake. Set

entire front edge of Upper Beam Jaw back from the Lower Beam Jaw the thickness of the metal to be bent by turning the Upper Beam
Adjusting Screws back as necessary. Retighten all screws and nuts.

ADJUSTMENTS - FINE ALIGNMENT:

1. A sample work piece, the entire length of the brake, should be clamped in place. Make a test bend by lifting the Apron a full 90º.

Release metal from brake jaws and check for straightness.

2. ADJUSTMENTS FOR BOWING: (Refer to figure 7 for location of Truss Nuts).

PROBLEM: Bows up.
SOLUTION: Release tension on Truss Nut (B).

PROBLEM: Bows down.
SOLUTION: Tighten Truss Nut (B). Level the Apron with the Lower Beam Jaw (see figure 3).

PROBLEM: Bows toward operator.
SOLUTION: Release some tension on Truss Nut (D) (depending on your brake).

PROBLEM: Bows away from operator.
SOLUTION: Tighten Truss Nut (D) (depending on your brake).

3. ADJUSTMENT FOR UNEVEN ANGLE OF BEND: If 90º sample bend is true at both ends but less than 90º at center of piece, loosen

Apron Mounting Bolts (figure 2) and lower the Apron approximately 1/32" by unscrewing the Apron Adjusting Screws. Retighten the
Apron Mounting Bolts and tighten Truss Nut (C, figure 7) until both jaws of brake are flush at brake center (see figure 3).

INCREASING JAW OPENING:

The opening between the brake jaws may be increased to a maximum of 1-5/ 8". With the Clamping Levers in the unlocked

position, turn the Lower Beam Lift Spring Rod Adjusting Nut (figure 2) at each end of brake downward until the desired opening is obtained.

CAUTION: The lower beam lift springs support the weight of the entire lower beam assembly when the brake is unclamped. Always adjust
the lower beam spring adjusting nuts with the brake in the unclamped position. If adjusted with the brake in the clamped position the beam,
when unclamped, will drop rapidly downward causing the clamping handles to snap backwards.

ENDWISE ADJUSTMENT OF LOWER BEAM:
If the ends of the Upper Beam Jaw and Lower Beam Jaw do not line up at the alignment points (X, figure 2), adjust as follows:

1. Loosen Upper Beam Adjusting Screw Lock Nut (figure 5) at both ends of brake. Turn Upper Beam Adjusting Screws until entire

Upper Beam is drawn back about 5" so the Lower Beam Bracket Stud alignment holes (figure 6) are easily accessible.

2. Use a wrench to loosen the Lower Beam Bracket Stud Nut at each end of the brake.

3. Insert a large screwdriver through the alignment hole in the Lower Beam Brackets and adjust the Lower Beam Bracket Studs as

necessary. Tightening stud on one end of the brake and loosening it on the other end will shift the Lower Beam to the right or left
permitting alignment of the Upper and Lower Beam ends.

CAUTION: Make sure the Lower Beam Bracket Stud does not bear too tightly against the inside leg. This will cause the lower beam to bind
and make the brake inoperative. Leave approximately 1/32" clearance between the lower beam bracket stud and the inside leg on each side
of the brake.

MAJOR BRAKE ALIGNMENT:
Follow the procedure listed below if brake is badly out of alignment. (if your brake does not have all the Truss Nuts referred to in these
instructions, disregard those steps.) A 30" length of one inch pipe will help attain necessary leverage when applied to the end of the wrench
supplied with the brake.

1. Loosen all Truss Nuts (A, B, C, D, E, figure 7) and Truss Rod Turnbuckle until all tension is released.

2. Tighten the Truss Rod Turnbuckle until the rods are snug at tension point (R). Tighten an additional 1/4 turn.

3. Tighten Truss Nut (B) until snug, -Tighten an additional three complete turns.

4. Check Apron at the alignment points (X, figure 2) to see if it is flush with top of Lower Beam Jaw (see inset, figure 2.) Up and down

movement of the Apron is controlled by turning the Apron Adjusting Screw (figure 2) at each end of the Apron.

5. Tighten Truss Nut (C, figure 7) until Apron is flush with Lower Beam Jaw at alignment point (Y, figure 2).

6. Tighten Truss Nut (E, figure 7) as tight as possible.

7. Tighten Truss Nut (A) until the Upper Beam Jaw is straight and parallel in relation to the Lower Beam Jaw.

8. Tighten Truss Nut (D) until the center of the Upper Beam Jaw bows forward slightly.

STRAIGHT BENDING:
Set Upper Beam Jaw back to thickness of metal to be bent. (See figure 5). Bends up to 135º may be achieved by raising the Apron until the
desired angle of bend is obtained. (See figure 8).

FLATTENED SEAM BENDING:
Bend metal to full 135º angle as explained above (figure 8). Remove metal from between the jaws and reposition it against the Upper Beam
as shown in figure 9. Lift Apron to flatten seam.

JOINTING:
Bend metal piece to full 135º angle. Remove metal from between the jaws and reposition it against the Upper Beam in same manner as
explained above. Lift Apron to complete bend. Do not flatten seam; but, allow for thickness of metal piece to be jointed.

The Roper Whitney No. 9 Button Punch Tool may be used to lock the two pieces together securely.

MINIMUM REVERSE BENDING:
Remove Apron Angle Iron Work Support and Apron Filler Plate (inset, figure 2). This permits 1/4" reverse bends to be made on all brakes
except Model Nos. 812, 1012, and 1214 will make a reverse bend of 3/8".

NOTE: When the Apron Angle Iron Work Support and Apron Filler Plate is removed, the brake capacity is reduced by 4 gauges.

To accomplish a minimum reverse bend, a metal lip is first bent to a 90º angle. Metal piece is removed and repositioned between the jaws as
shown in Step 1 (figure 11). Raise Apron 90º to complete bend, Step 2 (figure 10).

REPEAT BENDS:
Repeat bends can be made easily by using the apron gauge illustrated below. Make the first bend to the desired degree and clamp apron
gauge bar stop collar using set screw in position. Apron will contact stop and insure accurate repeatability of bend.

TINNER'S MOULDING FORMS:
One set of five standard sizes of Tinner's Mould; 5/8", 1", 1-5/8", 2-1/2", and 3" is available for all sizes of Combination Bending Brakes.
Remove the Apron Angle Iron Work Support and position the forming mold on the lip of the Apron (see figure 13). Use a hammer to tap the
moulding form clamps through the holes in the Apron of the brake. Metal piece part is wiped over the moulding form manually to obtain
desired radius.

RADIUS FORMING:
Radius Former Bars are available for all sizes of Combination Bending Brakes. These bars are available in sizes from 3/32" to 1" in
increments of 1/32". Sizes 1", 1-1 /2", 2", and 2-1/2" are available. The number of Radius Holder Fingers required depends upon the length
of the brake; 3 Holder Fingers are required for a 4 foot brake, 4 are required for a 6 foot brake, 5 are required for an 8 foot brake, and 6 for a
10 foot brake. Holder Fingers are all alike for all brake lengths. Shorter Radius Former Bars may be installed on longer brakes if desired.

INSTALLING RADIUS FORMER BARS:

1. Assemble the necessary number of Radius Finger Holders to the Radius Forming Bar as shown in figure, 14.

2. Increase the distance between the brake jaws by turning the Lower Beam Lift Spring Rod Adjusting Nut (figure 2) at each end of brake

downward as far as it will go.

CAUTION: The lower beam lift springs support the weight of the entire lower beam assembly when the brake is unclamped. Always adjust
the lower beam spring adjusting nuts with the brake in the undamped position. If adjusted with the brake in the clamped position the beam,
when unclamped, will drop rapidly downward causing the clamping handles to snap backwards.

3. When using a 1-1 /2" or larger Radius Forming Bar, an Auxiliary Lower Beam Jaw is required and should be inserted in position behind

the lower Beam Jaw (figure 15).

4. Loosen the Upper Beam Slide Clamping Screws (figure 5) and Upper Beam Adjusting Screw Lock Nuts at both ends of brake. Move

the entire Upper Beam back far enough to accommodate the assembled Radius Former Finger and Bar (figure 1 5).

5. Loosen Finger Clamp Bolts and hook Holder Finger into dove tail in Upper Beam. Position lip of Clamp over Upper Beam Jaw and

tighten Finger Clamp Bolts securely.

6. Move Upper Beam back or forward as necessary until front edge of Radius Former Bar is back from the Lower Beam Jaw the thickness

of the metal to be bent. (see figure 15). Tighten all Upper Beam Slide Clamping Screws and Adjusting Screw Lock Nuts.

7. With Clamping Lever in unlocked (up) position, adjust Clamping Lever Turnbuckles (figure 4) and Lower Beam Lift Spring Rod

Adjusting Nuts as necessary to obtain desired clamping pressure. Pressure should be firm enough so metal will not slip when clamped.

CAUTION: The lower beam lift springs support the weight of the entire lower beam assembly when, the brake is unclamped. Always adjust
the lower beam spring adjusting nuts with the brake in the unclamped position. If adjusted with the brake in the clamped position the beam,
when unclamped, will drop rapidly downward causing the clamping handles to snap backwards.

BOX AND PAN BENDING:
Box Fingers are available for all Combination Bending Brakes in widths from 1" through 6" in increments of 1/2", and an 8" width. They are
made in 6" and 8" depths.

The size and number of Box Fingers required can easily be determined as follows:

1. Largest dimension of box or pan determines the quantity of Box Fingers required.

2. Depth of box or pan determines the Box Finger depth.

Example: To make a box 10" wide x 15 " long x 7 " deep; use 8" deep Box Fingers in following combinations:
2 - 4" wide Box Fingers (or 1 - 8 " wide)
1 - 2" wide Box Finger
10" bend can now be made.
Add 1 - 5 " wide Box Finger
15" bend can now be made.

Any combination of Box Fingers that add up to the required total may be used.

INSTALLING BOX FINGERS
With Clamping Lever in unlocked position, proceed as follows:

1. Turn Lower Beam Lift Spring Rod Adjusting Nuts (figure 2) down to bottom at both ends of brake.

2. Loosen all Upper Beam Slide Screws and Upper Beam Adjusting Screw Lock Nuts. Move Upper Beam to the rear by turning Upper

Beam Adjusting Screws back to accommodate either 6" or 8" depth fingers.

3. Open Clamping Lever Turnbuckles (figure 4). A rod may be inserted through holes in Turnbuckles for ease in turning.

4. Loosen Finger Clamp Bolts (figure 16) and hook finger into dove tail of Upper Beam. Position lip of Clamp over Upper Beam Jaw and

tighten Finger Clamp Bolts securely.

5. Move Upper Beam back or forward as needed so that finger bending nose is 1/64" back from front edge of Lower Beam Jaw (figure 17).

Use Upper Beam Adjusting ,Screws (figure 5).

6. Tighten Upper Beam Slide Clamping Screws and Upper Beam Adjusting Screw Lock Nuts.

7. Adjust Clamping Lever Turnbuckles and Lower Beam Lift

Spring Rod Adjusting Nuts to attain proper clamping pressure. Pressure should be firm enough so metal will not slip when clamped.

NOTE: When using partial quantities of fingers, always mount fingers in the middle of brake to equalize strain. When bending with
fingers, capacity is 2 gauges lighter. A 14 gauge brake with Box Fingers installed will handle 16 gauge or lighter material only.

FINGER ALIGNMENT:
If bottom of Box Fingers are not flush, align as follows:

1. Choose a 4" to 6" width finger and set the Finger Leveling screws (figure 16) until end of each screw protrudes 1 /64" above

mounting surface of the finger. Lock the screws in this position by securely tightening Finger Leveling Lock Nuts.

2. This finger is now the master finger and should be mounted in the center of the Upper Beam. Be sure that finger is square when

tightening Finger Clamp Bolts. All other fingers are now adjusted to this master finger.

3. Set Finger Leveling Screws of remaining Box Fingers approximately the same as master finger. Mount finger on brake on right

side of master finger. Do not allow side of finger to touch side of master finger (allow about 1 /32"). Tighten Finger Clamp Bolts
and check to see if bottom of finger is flush with bottom of master finger. Adjust up or down as required by turning Finger
Leveling Screws in or out. This can be done from rear of brake while finger is clamped in place. Finger Clamp Bolts may require
slight loosening at times while Finger Leveling Screws are turned. Be sure Finger Clamp Bolts are securely tightened before
checking new adjustment.

4. When adjustment is correct, remove finger and remount on left side of master finger and check again. If bottom edges are not

level, correct as in step 3. Tighten Finger Leveling Lock Nuts securely.

5. Remove this finger and set aside. Then proceed to adjust all other fingers in the same manner.

6. When all fingers have been adjusted to master finger, they may be assembled on nose of brake in any combination and they will all

align with each other.
