Interesting article: savewright.org (#1)


Patent: Issued in April 1932

Both Wright Blocks patented in Great Britain & USA: GB402260A & US1894605A.

Finaly a glimps, of what John Lloyd Wright had in mind, for using these blocks… Still looking for building manual.


Box & content

There were 2 sets available, consisting of 36 and 70 parts. In the box you will find 8 different type of colored wooden interlocking blocks.

It would be very interesting what building intentions John Lloyd Wright had in mind. Please send me a copy of a manual.

According source 1: Probably some time in the mid-1950s, Wright developed a prototype for another toy construction block set, the “Timber Toy”. The set was including walls & floors. If you have any more information, please let me know!

Here mostlikely copy of these patents, issued inf 1935 & 1938:

(I have to say, some of those parts are very simular like the wooden Dometo building set.)

Somehow very appealing construction/building toy. I like the colors and the shapes. I guess my kids would definately build with it, creating al kind of fantasy/abstract buildings and structures…
