April Inventions

So, I thought I would share with you all some of the numerous items that have been invented throughout history in the month of April. There are many to choose from, so here is a small selection.
The roller skate patented on the 6th April 1869 Isaac Hodgson (No 88,711).[1]

A disposable syringe gained its patent on the 9th April 1974 (No 3,802,434), designed by Phil Brooks. [2] Whilst various forms of intravenous injection and infusion had been in occurrence from the 1670s, Charles Gabriel Pravaz and Alexander Wood who were the first to develop a syringe with a needle fine enough to pierce the skin in 1853. [3] As can be seen in the patent for Brooks design he mentions the various other needles available, however he notes the advantages of his disposable device.

An ironing board patent was granted to Sarah Boone on 26th April 1892 (No 473, 653). [4] Her improvement in ironing boards was produced to make a ‘cheap, simple, convenient and highly effective device’ which was particularly useful when ‘ironing sleeves and bodies of ladies garments’.[5]
