What is the Brief History of the Mortise Locks?
Mortise locks were known long before the birth of Christ. They are mentioned frequently in the Old Testament and mythology. At this time, the experts made the mortise cylinder of wood. They were broad and crude in design, yet their principle of operation has been the inspiration for today’s modern pin-tumbler mortise cylinder.
Mortise locks are different and heavier than cylinder locks; in their design, they use lever locks as a mechanism. The components of the mortise lock may vary slightly depending on the brand. However, the grounding principle is the same. These components have a solid metal construction and large springs built from resistant materials.
The Difference between a Cylinder lock and a Mortise Lock
Unlike a cylindrical lock, the mortise lock parts come disassembled. So, you must assemble the lock in the door correctly. Therefore an experienced locksmith should do the job for you.
The mortises have parts that need assembly around a pocket and cut into the door to fit the lock. Also, the mortise lock is different from the unit lock, a pre-assembled lock that comes in the box ready to be inserted in the cut area of the door.
What are the mortise lock parts:
- The lock body, which is the inside part of the mortise, is often seen cut out in the door
- The handle or lock trim comes in some designs of doorknobs, levers, handle sets, and pulls.
- The strike plate is a metal piece that keeps the hole in the doorway frame where you will fit it.
- The through Spindle is a long metal rod that connects the trim lock through the door and mortise lock body.
- The lock cylinder or keyed cylinder is the mechanism that operates the locking and unlocking function of the lock body when the user inserts the key. The mortise lock cylinder will have a cam, a rotating piece of metal that manipulates the handle’s ability to retract the latch.
- Escutcheon Plates or rose plates are responsible for fastening on either side of the door to create cohesion between the lock cylinders and handle.
- Hard Collars – This is a metal ring that spins on the lock cylinder, preventing any tool from removing the cylinder.
- Faceplate – The faceplate covers the internal systems of the lock’s housing parallel to the strike plate but on the door itself.
- Day/Night Switch – This switch will lock the door from the outside and keep it unlocked on the inside or engage to keep both sides unlocked.
How to Install Mortise Locks?
Homeowners can install mortise locks with a basic understanding and knowledge of woodworking tools and methods.
However, the installation requires precise rectangular cutting holes within the edge of the door. The homeowner or locksmith will use the traditional mortising jig, which makes the job much more straightforward. This carved hole formed on the edge of the door will host the primary body lock, which the expert will need to secure inside the available space with screws.
The other part of the mortise lock is the strike plate secured over the door jamb, where you should fit the locks into place to lock the door successfully. Nowadays, mortise locks use a lever mechanism instead of the old keyed cylinder locks.
