Patent of the week- ARTIFICIAL FOOT
Human beings are one of the greatest creations of God. Being born as a human, the first and one of the primary things that we are taught is to stand and walk on our own feet. What wheels are to a vehicle, feet are to the humans. But what if someone’s misfortune drives him/her to loose his/her feet?
The solution to this is an artificial foot. But, just making the artificial thing won’t really help until it solves the problem of comfort, durability and certain other standards that are to be met to make an invention usable by the ones in need of it.
Such an improvement was made by William L. Righen, in his invention of “Artificial Foot”, which got patent protection with the patent number US579009A, on 16th March, 1897. The improvements in artificial feet have a purpose of providing a simple and comfortable wearable device overcoming earlier defects and repairs.
It is made and fabricated with the lightest material having the required strength. It’s base is made up of suitable wood having a recess as it goes downward and another at the top. The recesses facilitates the passing of cords or tendons that help in joining the foot with the leg and support the ankle-joint, as well as it is attached to a socket plug to strengthen the flexible ankle-joint.
Improvement in artificial feet fills certain gap in the existing defects of earlier invention, in which repairing of parts were extremely difficult. The easy and comfortable adjustment of the parts in this invention made it an inexpensive and extraordinarily useful device.
