Introduction
The Ansonia Clock Company was one of the most prolific and influential American clock manufacturers of the late 19th century. Known for their ornate cast-metal, porcelain, and wooden mantel clocks, Ansonia produced a wide range of decorative and reliable timepieces during the 1880–1900 period. Their 1890s mantel clocks typically feature an American-style spring-driven movement, an eight-day run time, and a half-hour and hour strike mechanism. These clocks are admired today for their craftsmanship, historical significance, and mechanical durability.
This guide provides a complete overview of how to repair and restore an 1890’s Ansonia mantel clock. It covers the history of the company, the design of their movements, common mechanical issues, step-by-step servicing procedures, case restoration, and long-term maintenance. For restorers seeking authentic replacement parts, VintageClockParts.com offers carefully photographed components for Ansonia and other vintage American timepieces.
The Ansonia Clockmaking Tradition
Origins and early development
The Ansonia Clock Company traces its roots to mid‑19th‑century Connecticut clockmaking. The company evolved from earlier partnerships involving Theodore Terry and Franklin Andrews, who manufactured inexpensive brass clocks in the 1840s. Ansonia later expanded into New York and became known for producing high-quality decorative clocks in cast metal, porcelain, and wood.
Late 19th-century production
By the 1890s, Ansonia was producing hundreds of mantel clock models, many of which featured:
- Eight-day spring-driven movements
- Countwheel or rack-and-snail strike systems
- Cast-iron or wood cases
- Porcelain or metal dials
- Decorative bezels and glass
These clocks were designed to be both functional and ornamental, reflecting Victorian-era tastes.

Understanding Ansonia Mechanical Movement Design
The mainspring and power system
Ansonia movements use two mainsprings—one for timekeeping and one for striking. These springs store energy for an eight-day run and must be clean, lubricated, and free of cracks or fatigue.
The gear train
The gear train transfers power from the mainspring to the escapement. Wear, dirt, or bent pivots can disrupt smooth operation.
The escapement
Most 1890s Ansonia clocks use an American recoil escapement. Proper pallet alignment and pendulum adjustment are essential for accurate timekeeping.
Multi-Train Movement Configuration
Timekeeping train
The time train drives the hands and escapement. It must run freely with minimal friction.
Strike train
The strike train controls:
- Half-hour strike
- Hour strike count
- Gong or bell hammer
Most 1890s Ansonia clocks use a countwheel system to determine the number of strikes.
The Escapement, Strike, and Gear Train System
Escapement operation
The recoil escapement releases energy to the pendulum and regulates the clock’s timing. Wear on pallets or escape wheel teeth can cause erratic operation.
Strike system behavior
The countwheel strike system relies on notches in a wheel to control the number of strikes. Dirt, wear, or bent levers can cause miscounts or failure to strike.
Gear train wear
Common issues include:
- Worn pivot holes
- Ovalized bushings
- Dirty or worn gear teeth
Common Problems in 1890s Ansonia Mantel Clocks
Dried lubrication
Old oil becomes sticky and increases friction, preventing the movement from running properly.
Worn bushings
Excessive pivot wear causes gears to mesh improperly, leading to stoppage.
Dirty mainsprings
Dirty or dry mainsprings cause uneven power delivery and erratic timekeeping.
Strike miscounts
Bent levers or worn countwheel notches can cause incorrect striking.
Pendulum and beat issues
If the clock is out of beat, it will stop. Beat adjustment is essential.
Comprehensive Movement Servicing and Cleaning
Systematic disassembly and documentation
Each component should be removed, photographed, and labeled to ensure proper reassembly.
Cleaning techniques
Cleaning typically includes:
- Removing old oil
- Cleaning mainsprings
- Cleaning the gear train
- Polishing pivots
Mainspring servicing
Mainsprings should be removed, cleaned, inspected, and lubricated. Cracked or set springs must be replaced.
Gear Train, Escapement, and Strike Service
Gear and bushing replacement
Worn bushings must be replaced to restore proper pivot alignment.
Escapement adjustment
The pallets must be aligned correctly to ensure even impulses to the pendulum.
Strike system adjustment
Countwheel alignment, hammer lift, and gong clearance must be set correctly.
Case Restoration for Ansonia Mantel Clocks
Structural repairs
Wooden cases may require veneer repair, while cast-metal cases may need cleaning and refinishing.
Finish restoration
Depending on the case material, restoration may include polishing, waxing, or repainting.
Dial and bezel care
Paper dials can be replaced or stabilized; metal and porcelain dials can be cleaned carefully.
Final Assembly and Operational Testing
Movement installation
The movement must be reinstalled with proper alignment and secure mounting.
Initial setup
The clock should be tested for:
- Accurate timekeeping
- Proper strike count
- Even beat
- Reliable running over several days
Performance optimization
Fine adjustments to beat, pendulum length, and strike levers ensure long-term reliability.
Long-Term Care and Maintenance
Operating environment
Mantel clocks should be kept in stable temperatures and low humidity to protect wood and metal components.
Maintenance schedule
Cleaning and lubrication every few years extend the life of the movement.
Collector Value and Historical Significance
Market considerations
Ansonia clocks from the 1890s are valued for their craftsmanship, decorative appeal, and historical importance.
Documentation and preservation
Proper documentation enhances collector value and assists future restorers.
