Design and Components of Hand Crank Sewing Machines
A hand crank sewing machine, as a mechanical device, has an intricate design that enables sewing. Its external components include the bed, a rectangular frame that supports the fabric and a stationary hook, used for locking and releasing stitches, and an oscillating hook, that interlocks with the stationary one to make stitches.
The External Components
The main external components of a hand crank sewing machine include the bed, crank handle, and presser foot. The bed is the primary platform for the fabric, consisting of two parallel vertical plates that move upward or downward for thread tension adjustment and stitch regulation. The crank handle is a lever attached to the machine’s axle and rotates manually to power the hook movement. The presser foot is a metal plate attached below the bed and serves as a support for the fabric during the sewing process.
The Internal Components
On the other hand, significant internal components include the oscillating hook, bobbin, and shuttle. The oscillating hook is located within the bed, moving with the hook movement and creates a loop around the thread. The bobbin is a container for the lower thread, placed at the machine base and is lifted upwards by the rotary motion. The shuttle serves to transfer thread to the bobbin case. In the context of mechanical functionality, these components work together to interlock threads.
Materials and Durability
Hand crank sewing machines are constructed predominantly from cast iron and steel. Their robust design enables them to withstand heavy use and are often less prone to damage. For example, the bed and presser foot are fabricated from cast iron, providing stability and strength, while the oscillating hook and bobbin shuttle are made from durable steels ensuring minimal wear and tear.
Diagram Illustrations
A typical hand crank sewing machine layout can be envisioned as the crank handle, connected to the machine’s shaft, which then engages the stationary and oscillating hooks through linkages and gears inside the bed. These linkages ensure synchronized and precise movements of the oscillating hook.
These mechanisms contribute to efficient and synchronized operation ensuring quality stitches and precise control over sewing speed.
- The crank handle initiates and maintains the machine’s motion.
- The stationary hook holds the lower thread and interlocks with the oscillating hook, to generate a new stitch.
- The oscillating hook moves with the crank handle and completes the stitch while maintaining tension and alignment.
The materials selected for the hand crank sewing machine’s design ensure both functionality and durability, with steel and cast iron providing the necessary robustness to withstand various sewing requirements.
