SECTION 1
DESCRIPTION of the HEINTZ QUICK-ACTING
WATERTIGHT DOORS

THERE ARE THREE TYPES OF HEINTZ QUICK ACTING DOORS

(1) Sliding Dog Lever Type Door, Fig. 1, page 1, and Fig. 2, page 2.

(2) Rotating Dog Lever Type Door, Fig. 1, page 1, and Fig. 4, page 4.

(3) Rotating Dog Rack and Pinion Type Door, Fig. 6, page 6, and Fig. 8, page 8.

All of the doors operate quickly, easily and efficiently when correctly installed and adjusted, and when in dogged position make compartments tight.

All illustrations of replacement operations refer to the 26" x 66" Doors. The doors are made in various sizes and combinations of dogs, depending upon pressure requirements and bulkhead door openings.

Fig. 1-Outside view of Sliding Dog and Rotating Dog Lever Type Doors.

SLIDING DOG LEVER TYPE DOOR

This door is dogged or undogged by a 3/4 turn of

the hand lever, with minimum power requirement. The dogs are fully extended over the wedge before the final action forces the dogs down on the wedge.

Fig. 2-Inside view, Sliding Dog Lever Type Door.

HERE IS THE COMPLETE DOGGING OPERATION (Fig. 2, page 2):

(1) Closing the door against bulkhead frame,

(a) trips the interlock,
(b) releasing the operating mechanism.

(2) Turning the hand lever 3/4 turn,

(a) rotates the toggle arm,
(b) actuating the connecting rod, this

(c) rotates the dog crank which
(d) extends the dogs out over the wedge,
(e) lifting the inner end of dog bar by the cam on the dog crank,
(f) forcing the outer end of dog down on wedge,
(g) forcing knife edge into rubber gasket.
(h) The hand lever is held in final position by the toggle arm spring.

SECTION 2 INSTALLATION OF DOOR
The door is fabricated to a prescribed degree of accuracy and must be installed with careful attention to prescribed procedure. A TYPICAL INSTALLATION IS AS FOLLOWS (Fig. 9): (1) Straighten the bulkhead around the edges of the door opening. (2) Check with a straight edge across and along the edges of the bulkhead opening, to the exclusion of a 3/32" feeler. (3) Clamp door frame in place, center frame, square up to vertical knife edge and level up to horizontal knife edge. (4) Using arc weld, tack door frame in place following proper tacking procedure. During tacking, check dimensions between knife edges. (5) Permanently arc weld door frame in place following proper welding procedure. During welding, check knife edges for distortion. (6) With a straight edge, check knife edges to the exclusion of a 1/16" feeler. If necessary to straighten, use soft mallet. (7) Lift door onto hinges, see Figs. 11 and 12, page 11.		(8) Chalk-test knife edge contact on rubber gasket. (9) Adjust rubber gasket compression, see Figs. 15 and 16, page 13. WELDING ELECTRODE NOTE For welding corrosion-resisting steel frame to any bulkhead, use only 25-20 welding electrode, Grade IV-DC BUSHIPS Ad Interim Specification 46E4 (INT) of 15 April 1944 and amendment 2 of 15 August 1944 or later issue. For medium carbon steel frame, use medium steel welding electrode BUSHIPS Ad Interim Specification 46E3 (INT) of 1 November 1945 or later issue. All welding shall be in accordance with the applicable requirements of General Specifications, Appendix 5, Parts I and II. INSTALLATION NOTE When installing the Sliding Dog Lever Type Door, the bulkhead must be braced from bulkhead stiffeners to door frame along the vertical sides. This is done so that the deformation of the bulkhead will not produce a change in the size of the door opening sufficient to permit the dogs to slide off the wedges when subjected to heavy loads.

SECTION 3 INSPECTION, MAINTENANCE and REPAIRS
Periodic inspection and maintenance will keep the Quick Acting Doors watertight and insure smooth, easy operation. Each door should be inspected weekly,		and necessary maintenance should be completed without delay. A weekly routine of inspection, maintenance and repairs, carried out systematically is desirable.

All the materials for routine maintenance will be found in ships stores: carbon-tetrachloride or kerosene and paint thinner for removing grease, excess paint and other foreign matter, steel wool, 00 emery cloth and some clean wiping rags. HERE IS AN EXAMPLE OF GOOD ROUTINE INSPECTION AND MAINTENANCE: (1) Wipe off all dirt, grease and foreign matter with a wiping cloth dampened with carbon-tetrachloride or kerosene. (2) Scrape rust off all parts of the door. (3) Clean contact surface of dog and dog wedge with steel wool and wipe both surfaces with an oily cloth, leaving a thin film of oil.		(4) Clean rust and paint off knife edge contact surface with 00 emery cloth. (5) Remove all paint and rust from rubber gasket. It should be clean and pliable. (6) Examine all moving parts for excess wear or damage. If necessary, REPLACE NOW. (7) Operate door and check for smooth and positive dogging action. (8) Check compression between knife edge and rubber gasket. If adjustment is necessary, see Figs. 15 and 16, page 13. (9) Lubricate teeth of rack, pinion on Rack and Pinion Type Door, using rust-inhibitive grease. 1

SECTION 4 WEDGES REPLACEMENT

The wedges on all doors are the inclined surfaces, or points, where the dogs exert the pressure that forces the knife edge into the rubber gasket forming the watertight seal.

Fig. 10-Wedge ready for welding, Rotating Dog Type Door.

HOW TO REPLACE WEDGES ON ALL TYPES OF HEINTZ DOORS

First-Chip old wedge from door frame.

Second-Chip clean all old weld metal from wedge seat on frame.

Third-Hold wedge in place with "C" clamp, see Fig. 10.

Fourth-Using arc weld, tack wedge in place. Dog door and check for proper wedge position.

Fifth-Permanently weld wedge in place.

Sixth-Check rubber compression all around door, see Figs. 15 and 16, page 13.

NOTE: In tacking and welding, follow proper procedure (see welding note, page 9).

SECTION 5 HINGE PIN REPLACEMENT THERE ARE TWO TYPES OF HINGES ON THE HEINTZ DOORS:
1.-The conventional type with the elongated hole in the hinge blade. 2.-The Non-Sag Hinge which is designed to minimize sagging and misalignment of the door and to reduce frictional wear on the hinge pin. HOW TO REPLACE HINGE PIN: To Dis-assemble: Dog Door lightly. (1) File off peen of pin and remove hinge pin collar. (2) Remove hinge pin. (3) Slide washer from between hinge pad and hinge blade and inspect for scoring or excessive wear. Fig. 11-Hinge, assembly and exploded views, conventional type hinge.		To Re-assemble: (3) Replace washer between lower hinge pad and hinge blade. (2) Line up hinge pin holes and insert hinge pin. (1) Set new collar in place and peen over hinge pin. Test for free swing of door. Fig. 12-Hinge, assembly and exploded views, Non-Sag Type Hinge.
12
SECTION 6 RUBBER GASKET REPLACEMENT

The rubber gasket makes the door watertight where the door gasket meets the door frame knife edge.

The outer gasket retaining edge is part of the door panel, minimizing the danger of water leakage at this point. The inner gasket retaining edge is a bulb angle of one section which acts as a stiffener around the door, thus minimizing bulge or distortion of the door panel under water pressure.

The rubber gasket and method of replacement are the same for all Heintz Doors covered in this manual.

NOTE: When replacing rubber gasket, remember these Hints:

(1) Gasket joint should be at center top of door.

(2) Wet gasket with water and it will slide in place easily.

(3) Do not stretch rubber gasket when inserting in seat.

(4) Cut one inch too long, pull out part way, reinsert from cut end, forcing excess inch in place.

HOW TO REPLACE RUBBER GASKET, ALL HEINTZ QUICK ACTING DOORS (Fig. 13):

First-Insert screw driver at joint and pry out enough for hand-hold, pull out rest of gasket by hand.

Second-Clean out all foreign matter around gasket seat.

Third-Insert new gasket, use soft hammer and wooden wedge (see NOTE above).

Fourth-Check to be sure gasket is properly seated in retainers all around door.

Fig. 13-Rubber gasket replacement, all Heintz Quick Acting Doors.

SECTION 7
PACKING REPLACEMENT

Fig. 14-Installing Packing.

The packing is the medium for making the door watertight at the point where the outside handwheel or hand lever shaft pierces the door.

INSTALLING PACKING, ALL HEINTZ QUICK ACTING DOORS (Fig. 14):

From Outer Side of Door:

First-Remove packing plunger from outside operating lever (handwheel) shaft.

Second-Insert stick of packing. If stick packing is not available, roll bulk packing into a string form and pack into hole of shaft (use N.D. Spec. 33P29 Symbol 1425).

Third-Replace packing plunger and screw flush to shaft surface.

SECTION 8
RUBBER GASKET COMPRESSION ADJUSTMENT

The compression between the knife edge and rubber gasket may be varied by the compression adjustment on each dog on all Heintz Doors.

To determine proper preliminary adjustment, hold a piece of paper under dog, between knife edge and gasket, close door and hold in closed position by hand. Do not dog door. Adjust compression so that paper may

be pulled from between gasket and knife edge with a maximum drag. After preliminary adjustment has been completed for each dog, fully dog door and adjust each dog for a 1/8" depression of the knife edge onto the rubber gasket. The 1/8" depression may be determined by measuring a 1/8" pull-in of the door to the frame. Use a depth gauge or combination square and straight edge to measure from outside door panel to frame.

HOW TO ADJUST RUBBER GASKET COMPRESSION, ROTATING DOG TYPE DOORS (Fig. 16):

First-Back lock screw out part way, using Allen wrench.

Second-Turn dog spindle nut clockwise for more compression, counter-clockwise for less compression.

Third-Determine proper compression adjustment (see above).

Fourth-Tighten lock screw to lock compression adjustment.

Fig. 15-Rubber gasket compression adjustment, Sliding Dog Lever Type Door.

HOW TO ADJUST RUBBER GASKET COMPRESSION, SLIDING DOG LEVER TYPE DOOR (Fig. 15):

Fig. 16-Rubber gasket compression adjustment, Rotating Dog Type Doors.

SECTION 9
BUSHING REPLACEMENT

The bushings on all doors are made of oil-impregnated metal and are self-lubricating; they act as bearings for the moving parts.

During the replacement of any part the inspection of the bushings is regular procedure. Any sign of failure indicates the necessity of replacement.

Inspect bushing for cracks, breaks, wear or loose fit.

Remove bad bushing by driving out, using soft hammer and a piece of bar stock.
