PENNSYLVANIA 1927 John Warren Watson Company Stock Certificate #7 Automobile

Description

The certificate was dated September 9, 1927.
The Watson ”Stabilator” was described an automatic friction brake which acted to limit an automobile’s suspension spring recoil. Early shock absorbers, which were being developed, worked well on large bumps, but were not very effective in controlling minor motions.  Watson claimed that the “Stabilator” checked the spring’s recoil in proportion to the recoil force and prevented the car’s wheel from unloading and coming off the road which made for an uncomfortable ride, tire slippage and increased tire and brake wear.

The company was incorporated in Pennsylvania in 1927 and it was located in Philadelphia PA.
