Abstract: I have invented an improvement in the mode of fastening harness, which I effect by means of metallic clasps, screws, and pins, which I use as substitutes for the buckles usually employed for that purpose. Claim: The within described manner of making and using such fastenings for harness, wherever buckles have been heretofore employed for that purpose, without intending to confine myself to any particular pattern, or shape, in constructing them, but to vary them in any way I may think proper, while their construction and mode of operation remain substantially unchanged.

Abstract: This improvement consists of a combination of the common knob, having a neck or shank between, and smaller than the head, and foot of the knob, with a socket or plate either made wholly or having an edge or ring made of some soft metal capable of being set around the foot of the knob by turning in a lathe or otherwise without the application of heat. This socket is cast or otherwise made with a face, corresponding in form to that of the foot of the knob; and with a perpendicular edge or ring of soft metal around the outside of a depth somewhat greater than the thickness of the foot of the knob, the foot of the knob is then to be inserted into the cup, thus formed by the face, and *edge or ring of the socket, and the edge or ring is then to be turned down and let either in a lathe or otherwise close around the foot of the knob above the largest part of the foot so as to confine the knob closely and securely to the socket, or plate. If the use of the knob requires it, it may be made more secure from turning in the socket, by fitting the foot of the knob and the face of the socket together by a corresponding projection in the one and depression in the other, or by making the foot of the knob of some angular form with a corresponding hollow in the socket in the manner already practiced or otherwise. Claim: Our invention and improvement consists in The combination of the knob with the socket by means of the said edge or ring of soft metal when turned down, and set around the foot of the knob, and we claim nothing more.

Abstract: The process which I have adopted is an improvement of that ordinarily followed in which the conversion of blue lead into carbonate is effected by the heat generated by the fermentation of manure cooperating with the vapor of vinegar, but instead of the heat produced by fermentation I introduce steam from a steam boiler, and the vapor of vinegar produced also by artificial heat. The structure in which the conversion is effected may vary in size but for the purpose of description I give the proportions of one which I have used, and which I have found to answer the intended purpose in a very perfect manner. I build a basement usually of brick, which is thirty three feet long, twelve feet wide, and four feet high. I form two furnaces for heating boilers on each end of this basement. The furnace, and boilers for water I place in the middle of each end the boilers being five feet long by two in diameter. The boiler for acid is considerably smaller, a common hundred gallon still answering the purpose well. Claim: The effecting of the corrosion of the lead, and the conversion thereof into white lead by the admission of steam from boiling water, and of the vapor of vinegar, or other fluid containing acetic acid into a corroding chamber, which corroding chamber is properly charged with lead, and is surrounded in the manner herein described by layers, and banks of sawdust, tan, or other like material into, and through which layers, and banks steam from water is forced so as to enter the corroding chamber.

Abstract: We take a common screen or duster, such as are in common use by paper makers, and having taken out of it the shaft, we cause it to revolve on gudgeons made fast to its heads by means of a flange, and bolts. We then place in the interior of the screen, and extending from end to end thereof, four agitators, these are small cylinders, about six inches in diameter in which are inserted pins in number, and length according to the degree to which the operator may choose to agitate the rags. Claim: The aforesaid arrangement, and combination of the common screen or duster with the cylindrical agitators armed with pins rapidly revolving in various directions with the sun, and planet motion, constituting an improved machine for cleaning rags of dust for paper making.
