Following the sell-off, of the horticultural and hot water business, Thomas Messenger continued experimenting with new developments. Between 1876 and 1895, he registered or attempted to register 15 more inventions. As would be expected not all were successful, although a few of them appear to have been commercially viable. As time progressed, his inventions became more eclectic, although most of them were essentially based around his core skills.
In the first half of the 1880s, he submitted four water closet related patents application all successfully approved.
Between 1877 and 1891, he submitted another set of four patent applications for a more eclectic range of inventions, which may be why only two of them were successfully approved.
