Brunswick Phonograph: Door Hinge Mechanism

The door hinge on a Brunswick phonograph is likely a butt hinge, the most common type of hinge used on doors. Butt hinges are so named because they have two leaves that are mortised into the door and frame, allowing them to butt up against each other. There are three types of butt hinges: plain, ball-bearing, and spring-loaded. A plain butt hinge is typically used for lightweight interior doors and is joined by a pin. A ball-bearing hinge has lubricated bearings to reduce friction caused by heavy doors, while a spring-loaded hinge is calibrated to ensure a door closes with varying degrees of tension.

Hinge maintenance and repair

Hinges are a crucial component of any door, including those on a Brunswick phonograph. Proper maintenance and repair of hinges can ensure their smooth operation and prolong their lifespan. Here are some tips for hinge maintenance and repair:

• Regular Inspection: Conduct regular inspections of your hinges to identify any signs of wear and tear, such as loosening screws, rust, or misalignment. This proactive approach will help you address minor issues before they become major problems.
• Lubrication: Applying lubricant to the hinge mechanism can help ensure smooth operation and reduce friction. Choose a suitable lubricant, such as a silicone-based spray or lightweight machine oil, and apply it to the hinge periodically.
• Tightening Screws: Over time, the screws holding the hinge in place may loosen, causing the door to sag or become misaligned. Use the appropriate screwdriver to tighten the screws and ensure a secure fit.
• Adjusting Hinges: If your door is not closing properly or is rubbing against the frame, you may need to adjust the hinges. This typically involves loosening the screws slightly and repositioning the hinge until the door aligns correctly.
• Replacing Hinges: In some cases, hinges may become damaged beyond repair, or they may simply wear out over time. When this happens, it's important to replace the hinges with new ones. Choose hinges that match the size and style of the original hinges for a seamless fit.
• Hinge Repair Kits: For more extensive repairs, you can purchase hinge repair kits that include various tools and components needed for the job. These kits often contain items such as hinge repair plates, screws, and drivers, providing a convenient solution for fixing stripped screw holes or reinforcing hinges.
• Preventative Maintenance: To prolong the lifespan of your hinges, consider applying a protective coating, such as a clear sealer or paint, to prevent rust and corrosion, especially in humid environments. Additionally, regular cleaning of the hinges with a soft cloth can help remove dirt and grime buildup.
• Seek Professional Help: If you are unsure about repairing or replacing hinges yourself, consider consulting a professional handyman or specialist. They will have the necessary tools and expertise to ensure the job is done correctly, especially for more complex or antique phonographs.

By following these maintenance and repair tips, you can help ensure the smooth and proper functioning of your Brunswick phonograph's door hinges, keeping your cherished antique in good working condition.

Hinge types and uses

There are many different types of hinges, each serving a specific purpose. Choosing the right hinge for your project depends on where you plan to install it and the aesthetic you wish to achieve.

Butt Hinges

Butt hinges are the most common type of hinge used on doors and cabinets. They have two rectangular leaves that butt up against each other and are joined by a pin. There are several types of butt hinges: plain, ball bearing, and spring-loaded. Plain butt hinges are typically used for lightweight interior doors. Ball bearing hinges have lubricated bearings between the knuckles to reduce friction caused by heavy doors. Spring-loaded butt hinges are often used on screen doors and can be calibrated to open or close with varying degrees of tension.

Barrel Hinges

Barrel hinges are small and ideal for woodworking projects where you want the hinge to be concealed, such as small cabinets or jewellery boxes. They are typically made of brass and open to 180 degrees.

Concealed Hinges

Also known as invisible, hidden, or European hinges, concealed hinges are used on entry and interior doors, cabinets, and furniture. They provide a smooth, uninterrupted appearance and enhance security since they cannot be tampered with from the outside.

Knife Hinges

Knife hinges, also called pivot hinges, resemble a pair of scissors and are attached at a pivot point. They are commonly used in cabinets for overlay or inset doors and are barely noticeable once installed.

Piano Hinges

Piano hinges, also known as continuous hinges, have a central pin and same-sized leaves that run the length of what they are attached to. They are perfect for fold-down desks, cabinet doors, and storage boxes.

Strap Hinges

Strap hinges are characterised by their long, narrow leaves that provide extra stability. They are commonly used outdoors on gates and indoors on cabinets as a design element.

Hinge installation

To install a hinge on a Brunswick Phonograph, you will first need to identify the type of hinge. In this case, the hinge is likely to be a butt hinge, as these are the most common type of hinge used on doors.

• Identify the location of the hinge on the door and frame. Mark out with a pencil where the two leaves (or plates) of the hinge will be mortised into the door and frame.
• Using a chisel, carefully cut out the areas you have marked to create a space for the hinge leaves. The hinge leaf should sit flush with the door and frame, so ensure the depth of your mortise is correct.
• Place the hinge leaves into the mortised areas and mark the screw holes with a pencil.
• Drill pilot holes for the screws.
• Screw the hinge leaves into place, ensuring the hinge is secure and the knuckles of the hinge align.
• Test the hinge to ensure it opens and closes smoothly.

If your hinge is a ball bearing or spring-loaded butt hinge, the installation process will be similar. However, ball bearing hinges will have lubricated bearings between the knuckles, and spring-loaded hinges will have a spring mechanism that will need to be calibrated to the desired tension.

For other types of hinges, such as barrel hinges, knife hinges, or strap hinges, the installation process may vary.

Hinge lubrication

Lubricating the hinges on a Brunswick phonograph is a straightforward task that can be done at home. Here is a step-by-step guide to help you get started:

Purchase a Suitable Lubricant:

• Look for a lubricant that can penetrate grime and coat the hinge's interior effectively. Silicone spray lubricants like Blaster or Tri-Flow are widely available and suitable for hinges.
• Lithium grease is another option, offering dust resistance and available in large quantities at auto parts stores.
• Food-grade oils like olive, canola, or coconut oil can be used in a pinch, but they tend to attract dust and grime.

Find and Remove the Hinge Pin:

• Open the phonograph door to access the hinges.
• Locate the round hinge pin between the flat plates of the hinge.
• Use long pliers to carefully pull out the pin. If it's challenging to remove, try using a screwdriver or penetrating lubricant spray like WD-40 to loosen it.

Clean and Lubricate:

• Clean the hinge pin and plates with a disposable rag or paper towel to remove old grease and grime.
• Apply a thin coat of lubricant directly onto the hinge pin and inside the hinge.

Reassemble and Test:

• Push the hinge pin back into place, ensuring it is secure.
• Open and close the door several times to distribute the lubricant evenly.
• If the squeaking persists, repeat the process for each hinge until the noise disappears.

Clean Up:

Use a rag or paper towel to wipe away any excess lubricant, grime, or dust from the hinge area.

Tips for Stuck or Rusty Hinges:

• If the hinge pin is difficult to remove due to rust, soak it in penetrating lubricant spray for up to 12 hours before attempting to remove it again.
• Gently tap the end of the pin with a screwdriver to push it out.
• Straighten a bent pin by placing it on a cement floor and tapping it with a hammer.
• Use emery cloth to sand down a rusty pin, removing rust and creating less resistance.

By following these steps, you can effectively lubricate the hinges on your Brunswick phonograph, ensuring smooth and quiet operation.

Hinge replacement

If your phonograph has a butt hinge, you can replace it by first removing the pin that joins the two leaves. You can do this by tapping it out with a hammer and punch. Once the pin is removed, separate the two leaves and remove the old hinge. To install the new hinge, place the leaves in the mortise and join them with the pin. Ensure the pin is secure by tapping it gently with a hammer.

For a ball bearing hinge, the process is similar. Remove the old hinge by taking out the pin and separating the leaves. Install the new hinge by placing the leaves in the mortise and joining them with the pin. Ensure the ball bearings are lubricated to reduce friction.

If your phonograph has a spring-loaded hinge, you will need to adjust the tension to calibrate how the door opens and closes. To replace the hinge, remove the old one by taking out the pin and separating the leaves. Install the new hinge by placing the leaves in the mortise and joining them with the pin.

In some cases, you may need to remove the door to replace the hinge. If the door is damaged or the hinge is broken, it may be easier to replace the entire door.

When choosing a replacement hinge, consider the weight and frequency of use of your phonograph door. Plain butt hinges are typically used for lightweight interior doors, while ball bearing hinges are more durable and ideal for heavy or frequently used doors. Spring-loaded hinges can be calibrated to assure the door closes behind you.
