In making a survey of the farm nachinery we find a great many cases vhere the operating conditions are o -severe that the amount of oil used ind the method ot application is lnade-luate lnade-luate to insure a reasonable life ot hose bearings, such as the wheels of 'print: tooth harrows, hay rake wheels, lisc-harrow bearings and many other inplement wheels. This condition nay be improved by equiping such icarings with compression grease Mips, sometimes culled "hardoilers." Jfton the oil hole has been threaded it the factory to receive the grease up nnd not provided with the cup. rhe pressed steel grease cups may be secured In three capacity sizes, in each C the different shank sizes. The ihank sizes refer to the threaded end 3f the cup and these threads are Known as the standard pipe sizes and may be secured in the following dives: one-eighth inch, one-fourth Inch, three-eighth inch nnd one-half inch. The one-eighth and one-fourth aro the most useful sizes nnd will take care of nearly all conditions. We recommend recom-mend that all fanners keep some of these grease cups on hand and also provide themselves with the one-eighth one-eighth and one-fourth inch pipe top for threading the holes. Also secure an eleven-thirty second inch twist drill and a twenty-nine sixty-fourth drill for the purpose of drilling the holes to be toped out to receive the grease cups. It Is less difficult to keep the cup grease clean, and it having n heavier body is more effective in holding metal surfaces apart than the lighter oils, so it should tie easy to see the advantages of this method of lubrication. lubrica-tion. A great many of the implements are now being equipped with this system sys-tem of lubrication at the factory. TO PROLONG THE LIFE OF FARM , MACHINERY. By A. H. Powell, Associate Professor of Farm Machinery, Utah Agri- ' cultural College One of Uie problems the farmer has - to contend with is that of reducing ( the expense of repairs ond replaee-i replaee-i menrs and obtaining the maximum life I of the power farming equipment, and if the following suggestions are carried car-ried out It will result in a material i- reduction in the cost of repairs and k will also save considerable time. 51 You will observe a large number of the working parts of iurm implements e aro lubricated by means of n oil hole or cup located on the upper side of '' the casiing or bearing, nnd wnli a very few exceptions these oil holes ure unprotected un-protected from the dust and sanu that always accumulates on tha Lop of such castings. Si In operation these oil notes become partly filled with sand and dirt, ihen when the lubricating oil Is applied it carries this dirt into . the bearing, the results being a worn cut bonring in a very short time. There " are only a very few people who fully understand how injurious u small e grain or sand really is when it is e crushed between two metal surfaces and then supplied with oil, thus bring-j bring-j ing about what may be termed as an II ideal grinding condition. The greater c- portion of such injury may he prevented pre-vented by making n cover for nil of the oil holes and cups. This may be o accomplished by the use of a small piece of thin leather secured tn the " casting in such a way that it will he . held firmly in place, having an ex- j tend6i! piece that covers the oil hole. In addition wc find that men who are using oil f';r lubricating pui-poses are not careful r.r.ugh in keeping the con J tainers clci-u nnd keeping the supply In. a cleai piece. With all high speed A |
