It is likely that Scales was from a family established at Kingston-upon-Hull since at least the early fourteenth century. Richard Scales served as a chamberlain and bailiff of the town in the late 1330s and early 1340s and another John Scales exported wool through the port there in the late 1390s.
It is likely that Scales had business dealings in London, and he was certainly active in the overseas trade. During the mid 1440s he pursued lawsuits at Westminster against Thomas Crosse, a draper from the City, over a bond for just over £20 that he had received from the latter in 1439. Crosse responded by claiming that he had entered the security under duress, while a prisoner of Scales and his associates at Hull.
Before entering the Parliament of 1447, Scales served terms as a chamberlain and bailiff of Hull and became one of the first aldermen of the town. At Michaelmas 1449 he was chosen as mayor of Hull and in October the same year he was appointed to his first ad hoc commission. A powerful group led by Sir John Constable*, the commissioners were empowered to inquire into an act of piracy against a Flemish merchant.
Scales’s fellow Hull MP on this occasion was Richard Anson, a committed Yorkist, and, as Parliament opened on 7 Oct. 1460, Scales offered surety for his fellow MP in the Exchequer, where Anson was charged with illegally shipping overseas 500 marks which he had collected in customs’ revenue at Hull. During the parliamentary recess, Anson fell on the Yorkist side at the battle of Wakefield, but it is not known whether Scales shared his friend’s political sympathies. He seems to have remained at Westminster long after the parliamentary session ended on about 1 Dec., not returning to Hull until the 26th, only a few days before that battle.
Scales quickly adapted to the accession of Edward IV, and in the spring of 1461 he and other aldermen rode to offer their submissions to the new King at York.
In his will of 5 Oct. 1467, Scales requested a funeral, burial and obits in the church of the Holy Trinity at Hull, where his wife already lay buried. He assigned the sum of 3s. 4d. to every mendicant friary in the town, left 6s. 8d. towards the rebuilding of the chapel of the local guild of the Holy Trinity and gave 10s. to St. Mary’s chapel. Scales directed his executors to dispose of his not inconsiderable holdings at Hull for the benefit of his soul and those of his wife and daughter, who had also predeceased him. These included the properties in Old Beverley Street as well as tenements in Old Kirk Lane and Champagne Lane. He appointed as his executors three local merchants, Thomas Wilton, William Thornton and John West, and a chaplain, William Bower. Probate was granted on the following 17 Nov.
