1) What Is It Called?
This tool is commonly known as a:

  • Vintage Beer Bottle Capper
  • Antique Bottle Capper
  • Bottle Corker / Capper (Combo tool)
    Collectors and sellers often label it as a “capper/corker” because many models were designed to handle either crown caps or corks, depending on the pressing head attachment.

2) What You’re Looking At (How It’s Built)
From the photos, the key features match a classic bench-style, lever-operated capper:

  • Cast-iron frame with a wooden base (meant to sit on a counter or bench)
  • A vertical rack (toothed bar) and gear mechanism that lets you adjust height for different bottle sizes
  • A long lever handle that multiplies force so the user can press a cap or cork in place with one smooth motion

3) When Did It First Appear? (Origins and Time Period)
Bottle-sealing tools existed for centuries, but this specific style became popular as packaging modernized:

  • Corking tools were widely used in the 1800s, when corks were the standard seal for beer, soda, and spirits.
  • Crown caps (the crimped metal bottle cap used on beer and soda) were introduced in the late 1800s, which drove demand for practical mechanical cappers.
  • Bench-mounted, cast-iron lever cappers like this became especially common in the early 1900s through the mid-1900s, used by small bottlers, taverns, general stores, and home bottlers.

4) What Was It Used For? (Primary Purpose)
The capper/corker’s job was simple but essential: seal bottles reliably and repeatedly.

Main uses:

  1. Capping beer and soda bottles with a crown cap
    • The tool crimps the cap skirt tightly around the bottle lip to prevent leaks and preserve carbonation.
  2. Corking bottles (on models fitted with a corking plunger)
    • The lever compresses and seats the cork into the bottle neck.

Why it mattered:

  • A strong seal protected flavor, freshness, and carbonation
  • It enabled consistent bottling for small-scale commercial operations and home use

5) How It Works (Simple Step-by-Step)
A typical workflow looks like this:

  1. Set bottle height: Slide the head assembly up/down using the rack-and-gear adjustment.
  2. Place the cap/cork:
    • For crown caps: set a cap on the bottle mouth.
    • For corking: position a cork beneath the pressing head (if equipped).
  3. Pull the lever: The lever drives the head down with high force.
  4. Seal is formed:
    • Crown cap: the cap is crimped around the rim.
    • Cork: the cork is pressed firmly into the neck.
  5. Release and remove: Lift the lever and take out the sealed bottle.

6) Why Collectors Like It Today
These tools remain popular because they combine:

  • Industrial-era craftsmanship (heavy cast iron, mechanical gearing)
  • Practical function (many still work perfectly for homebrewing)
  • Decor value (a striking vintage countertop piece)

Key Identifier in Your Photos:

  • The tall toothed column and gear-driven adjuster strongly suggest a bench-style adjustable capper/corker, designed for multiple bottle heights and repeat use.
