Google patents is where I searched - you can also got the USPTO site:
http://www.uspto.gov/, and use their search engine which allows more search parameters to be entered, hpwever every time I go there a) the site has changed and b) it has becomes more difficult to find the search page for older patents - Google is much easier to use... DATAMP may also be worth searching:
http://www.datamp.org/ Images can often just be saved using right click of the mouse, or use a simple tool like MS's Snipping Tool - failing that use the Save Screen button, paste into Paint and edit from there...
Just playing with Google (it's pouring with rain outside) - you can set search parameters such as date, e.g. 1880 to 1910 - I've tried all combinations of cheese, cutter, table, legs, rise & fall, bevel gear, rack and pinion - as yet no luck...
