thomas. Backhoe. June 04th , 2018.
The patent for the first reversible seat was developed at Wain-Roy by Carroll Arnold and Vaino Holopainen and then filed by Vaino under patent #2784768 and in June 1954 Vaino filed patent # 2781927 for individually controlled outriggers. John S. Pilch of Ware Machine Works Ware MA developed the first 4-bar linkage to achieve greater bucket digging and dumping rotation. Pilch filed for patent #2678741 in September 1950. The 4-bar linkages were also used on the Wain-Roy backhoes after 1954.
With the advent of hydraulic powered attachments such as a tiltrotator breaker a grapple or an auger the backhoe is frequently used in many applications other than excavation and with the tiltrotator attachment serves as an effective tool carrier. Many backhoes feature quick coupler (quick-attach) mounting systems for simplified attachment mounting dramatically increasing the machines utilization on the job site. Backhoes are usually employed together with loaders and bulldozers. Excavators that use a backhoe are sometimes called "trackhoes" by people who do not realize the name is due to the action of the bucket not its location on a backhoe loader.
In 1960 Vaino Holopainen was introduced as "Mr. Backhoe" to Henry Ford II. Wain-Roy continued to produce them for Ford until 1963 when Ford made their own and Wain-Roy could not compete with such a large company after that. Wain-Roy Corporation bought the AC Anderson Company and then the company suffered.
