METHOD OF REPAIRING SCORED CYLINDER WALLS.
Specification of Letters Patent.
Patented Jan. 1'7, 1922.
Application filed December 1, 1919. Serial No. 341,720.
To all 107M772 it may concern:
Be it known that I, GEORGE L. BARRETT, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented a new and useful Method of Repairing Scored Cylinder \Valls, of which the following is a specification.
My invention relates to improvements in the method of repairing motor cylinder walls which have been scored by loose wrist pins, or other causes thereby eliminating the necessity of having the cylinders rebored.
To carry out the aim of my invention, I employ metallic means for filling in the score, which filling is of such hardness and relatively high melting point as to withstand wear and heat, so that the cylinder, when repaired, will be substantially as good as a rebored, or new cylinder.
The objects of my present invention are to provide a new and simple method of repairing the scored part of a cylinder which includes a novel way of preparing the score with a special flux and then filling the score with a special metallic compound.
WVith the above and other objects in view, the invention consists in the use of a flux and metal composition fully described in the following specification and finally pointed out in the claim hereto appended.
Referring to the accompanying drawing forming a part of this specification wherein like characters of reference denote similar parts throughout the several views:
Fig. 1, represents a cross-sectional view of a part of a cylinder showing a score longitudinally thereof.
Fig. 2 represents a cross-sectional view of a part of a cylinder showing the score after it has been filled in.
Fig. 3, represents a cross sectional view of a part of a. cylinder showing the filled, or repaired part smoothed off flush with the surface of the cylinder.
When it is desired to repair, or fill in the score 1 of a cylinder wall 2, the score 1 is first thoroughly cleansed free from all oil, and foreign matter. After this cleansing operation, the score is then prepared for its filling by freely applying a flux thereto which prepares the scored surface so that the metallic filling will adhere thereto.
For the purpose of cleansing the scored surface and preparing it for filling compound, I use a liquid flux made as follows: muriatic acid ninety per cent; zinc eight per cent; soap preferably brown laundry soap, one percent and borax one per cent. The solution is prepared, or mixed as follows:
The zinc, soap and borax are all placed into the muriatic acid at the same time, otherwise thesoap will not dissolve.
The flux solution is applied as often as is necessary to make a metallic compound, or filling stick to the cylinder wall.
The filling compound, which is metallic, is made as follows: lead fifty per cent; tin forty per cent; zinc nine per cent; antimony one per cent. lVhile the proportions of this metallic compound may be varied slightly, I have found in practice the metals to firmly adhere to the walls of a scored cylinder repaired with the flux previously described and to produce a first class and permanent repair job.
The filling compound 3 is formed into bars and applied to the score by means of a soldering iron Or other tool. As the filling compound is heated it runs into the score, when held over the score and sufficient heat is applied thereto so that it may be worked into the score in a molten mass. The walls of the cylinder adjacent the score 1 are preferably heated when the compound is being worked into the score. This heat may be applied in any desirable manner, such as with a torch. The cylinder wall and compound are kept heated, the compound to the melting point until the compound has thoroughly adhered to the score surface of the cylinder. IVhen the filling has adhered to the scored cylinder wall, it is allowed to cool. The score is filled high with filling compound, as shown in Fig. 2, and after it has cooled it is preferably scraped with a tool harder than the compound and softer than the cylinder wall, until the surface of the filling is flush with the surface of the cylinder wall, as shown in Fig. 3.
The many advantages of the-hereindescribed invention will readily suggest themselves to those skilled in the art to which it appertains.
What I claim is:
The herein described process which consists in treating a score in the walls of an mony, then heating thefilling and adjacent internal combustion engine cylinder to a cylinder Wall, then subjecting the filling to 10 liquid solution comprising ninety per cent the agitating action of a soldering copper, muriatic acid with one per cent borax, one and finally removing any excess filling by per cent brown laundry soap and eight per scraping the material.
cent zinc dissolved therein, filling the score In testimony whereof, I have hereunto with fifty per cent lead, forty per cent tin, signed my name to the specification.
nine per cent zinc and one per cent anti GEORGE L. BARRETT.
