RECENT AMERICAN PATENTS. The following are some of the most important im provements for which Letters Patent were issued from the United States Patent Office last week; the tion relates to a new and improved raking device for harvesters of that class in which a rake is attached to an endless belt or chain. The object of the inven tion is to obtain a raking device of the class specified which will discharge the cut grain from the latform in a perfect manner and from either the side or rear of the platform according to the position in which the working parts are placed; the parts being so arranged as to cause the rake while performing its work to present itself properly to the cut grain while passing over the platform and to discharge the grain properly therefrom ; the speed of the rake being also rendered capable of being varied or modified as oc casion may require. L C. Crane of Edgerton Ohio is the inventor of this improvement. their equivalent which hold the plates between the successive cutting operations; also in certain novel drawn back and until the proper time for moving them forward; also in certain novel means of libera ting the tongs to allow them to be moved forward by the weight or other means employed for the purpose make them raise and lower the plate during the turn ing operation. P. S. Bradford of Bridgewater Mass. is the inventor of this improvement. a series of vats containing the various liquors used sufficiently long to enable the liquid to produce the desired effect; without interrupting or stopping the notion of the fabric through the apparatus. In order to obtain this object each vat is divided in two or more chambers or compartments and the fabric is caused to arrange itself in each compartment in a serpentine pile of more or less layers according to compartment or vat f and as the fabric passes through the apparatus the lowest layers of each pile are drawn out from the botton while at the same time fresh layers are formed on the top and the
