Patents Hatchway Device

1915

Invention Slides "Strongbacks" Instead of Removing Them

Capt. R. T. Anderson of San Francisco, Cal., has been granted a patent on a device for sliding the "strongbacks" in a hatch to either one side or the other, instead of lifting them out singly and placing them on deck while the cargo is either taken on or discharged.

Under present building plans each of the "strongbacks" is lifted out and laid on deck after the hatch covers have been taken off. This requires some time. Under the Anderson plan these heavy beams are slid back to either one side or the other and then are pulled to position again and pinned in place after the work in the hatch is completed.


Invents Seat for Motorman

Revolves and Can Be Adjusted at Any Angle

A new motorman's seat invented by a Vermont man is said to have an advantage over the ordinary motorman's seat in that it has both a revolving and stationary top. It can also be adjusted at almost any angle by means of a mechanism.

This seat has been in use on all of the cars of the Burlington Traction Company for several weeks and has been found to be satisfactory. It is specially designed for air controlled cars. The work of their manufacture will be begun on a small scale at first, or until a factory can he built or secured.


Here's World's Smallest Saw

Quarter-Inch Diameter and Made for a Purpose.

Probably the smallest "buzz" saw in the world is one that has just been made by Ambrose Thomas, a violin maker. Thomas made the saw blade by hand and it is only one-fourth inch in diameter. The teeth are constructed the same as those on large saws. The blade is attached to a foot-power dentist drill and will saw the hardest of lumber with ease. Thomas uses it for sawing groves in the edge of violins to insert the variegated wood.
