Fenders you ask? Well they weren't just for cars. In 1822 a patent was given to:
To Thomas Ibbotson, of Sheffield, in the county of York, Fender Manufacturer; for a Fender capable of being extended or contracted in length, so as to fit fireplaces of different dimensions. Dated Nov. 28, 1822.
To Thomas Ibbotson, of Sheffield, Yorkshire, fender manufacturer, for his improved fender, capable of being extended or contracted in length so as to fit fire-places of different dimensions.—28th November.
If you're unsure like I was about which part of the fireplace a fender was place do a google image search and you'll see a variety of fenders.
Thomas Ibbotson manufactured a variety of items several of which are being sold today as antiques, even on eBay.
