Hess Dynamobil Table Saw Grouping, circa late 1920s, early 1930s. A grouping of Hess Dynamobil table saws. On the left is a third generation Dynamobil with tablesaw; to the right is a second generation, and in the foreground is a stand along tablesaw accessory. |

A third generation Dynamobil with fall hammer. The accessory underwent no mechanical changes for the third generations, but had it’s graphics slightly altered. | |||
 |
A third generation Dynamobil with three accessories; polisher / tumbler with new color scheme, twin drop hammer, and newly designed twin trip hammers. I have seen very few of the third generation pieces and suspect that Hess closed it’s doors soon after manufacturing began. | |||
 |
A small size third generation Dynamobil on tinplate base with trip hammer. | |||
 |
A first generation Dynamobil with a very large trip hammer. This trip hammer was spring loaded and the tension could be adjusted, resulting in a louder, more forceful blow. | |||

Early first generation "Interchangeable" Dynamobil, circa 1900 Base: L 10.5” (26.66 cm), W 4.625” (11.75 cm), H 3.25” (8.25 cm), Marked: “Dynamobil”, “Orig. Hess”, “D.R.G.M.”, “JLH” logo, “H Shield” logo. This “60” drop hammer accessory unmarked but many were marked “60”. Rotating mill marked “61”, Trip hammer marked “62”, “JLH” logo, “H shield” logo. The first and only “Interchangeable” Dynamobil toy I have ever seen. A base plate is mounted on the board along with the flywheel motor and is marked “60”, “61”, and “62” for placement of the accessory. Locking pins hold the accessory to the board. This is a very early model, possibly a prototype that did not make it to full mass production. I don’t know whether these were sold separately or as a kit which included the motor with board and separate accessories. |

 The “Tippmobil Motor” on left compared to the Hess Dynamobil on right. |
The Hess Dynamobil (modified) lives on with Tippco When Hess went bankrupt in 1934, it appears some of the tooling, parts, patents, etc., were sold to Tipp and Co. There are at least three toys which carried some semblance of Hess manufacture; The Tippmobil Tractor which is almost identical to the Hessmobil tractor; The Tippmobil Motor, a flywheel cranked motor with very different outside construction and graphics; An unnamed sedan with the same unmistakable cranked flywheel motor as the Hessmobil. The motor and tractor can be seen in the 1937 Tipp & Co. catalog. |

 Tippco, Krauss and successors flywheel motors grouping |
Hess competitor - Krauss and Company Hess was not the only manufacturer to have success with the flywheel motor toys. Wilhelm Krauss Company and its successors produced flywheel motor powered toys for many years. At one point, Hess filed a lawsuit against Krauss claiming patent infringement for which Hess won judgment. Below are a few examples over several decades of production. Krauss named their devices “Centrimotors” and even produced a flywheel powered vehicle named “Centrimobil”. Their toys were available as individual flywheel motors as well as in combination with many different accompanying accessories. |

Tippco Products With Hess Similarity, circa 1935 Shown are several products from Tippco with strong Hess similarities. Two of these products have been seen in one of Tippco’s catalogs; the Tippmobil Motor and the Tippmobil Tractor. The sedan, possibly a prototype that did not make it to mass production, has not been observed in any catalog, but it clearly utilizes the Hess cranked flywheel motor design. Tippco registered the names “Tippmobil” (472582) and “Tippmobiltraktor” (471974) in 1934 / 1935 shortly after Hess declared bankruptcy. The Hess influence is undeniable.
