In 1917 the Davis Manufacturing Co. engine plant in Milwaukee,
Wisconsin was purchased, becoming Avery Co. Plant No. 3. They were
then prepared to build all of their own engines.

The Glide automobile plant in Peoria Heights, Illinois was a
side enterprise of J. B. Bartholomew’s. He manufactured the
Glide automobile for several years and in 1920 decided to bring the
plant into the Avery Co. fold as plant No. 4 for the manufacture of
trucks.

With four plants comprising the Avery Co. and an employment of
four thousand people, it appeared that David McCullough’s
prophecy was well on the way towards realization.

Times were changing, however, as new developments were given
impetus by World War I and competition was becoming a greater
challenge in manufacturing industries. In the earlier years new
inventions could be incorporated into machines for production as
saleable products without any appreciable amount of engineering and
development work. The time was now approaching when products had to
be built better in order to compete for the customers dollar and to
stay sold. An inventor with a few draftsmen could not accomplish
this task alone; it required a program of engineering, research and
training of young men to execute the program.

The company realized that competition and product obsolescence
were challenging their products. Two major developments in the far
West were beginning to be felt in the Mid-Western area. The track
type tractor and the combine-harvester were challenging the large
steel tire wheel tractor and the stationary threshing machine. Mr.
Bartholomew was quite capable of conceiving new and advanced ideas
for products to create new markets. Here are some of the later
developments. In 1917 the small motor cultivator appeared featuring
a friction drive transmission with infinitely variable speeds.
Later when the power was increased with the use of a six cylinder
engine the friction drive was not adequate and a conventional
clutch and sliding gear transmission was adopted. They built as
high as fifteen hundred units a year. Here was a machine that the
farmers were eager to own, but lack of proper engineering follow up
in the field left these machines in need of de-bugging and then
popularity was retarded as a result.

A blade attachment was made for the motor cultivator and it was
sold under the trade name of Road Razer. This one-unit grader idea
was later carried further with the development of a larger machine
permitting the blade to be placed between the axles. The blade
assembly was mounted on a ball bearing slide rail which permitted
quick side shifting of the blade.
