J. J. DUGAN METHOD OF MAKING COMPOUND STOCK Filed April 1925 Patented Aug. 14, 1928.
UNITED STATES PATENT OFFICE METHOD OF MAKDTG COMPOUND. STOCK.
Application filed April 9, T825. Serial No. 21,871.
My invention relates to compound metal stock and the method of making the same.
In the construction of certain articles, such as piston rings, it is desirable to have metals 6 of difierent characteristics. The stock may therefore be made of bronze and steel; the bronze being used in the piston ring to reduce friction and the steel being used to provide a reinforcement for the bronze. In such a combination of metals in a piston ring, the steel band checks premature expansion of the bronze thereby reducing unnecessary friction between the ring and cylinder wall.
By the method of locking the two metals together as herein-disclosed, the union is stronger than when the same metals are united bywelcling.
Referring to-the drawings for a more complete disclosure of the invention:
Fi re 1 is a cross section of the two meta s before being locked together.
Fig. 2 is a cross section of the finished piece of compound stock, after the tw metals have been locked together.
Fig. 3 is a cross section of a round bar of compound stock.
The part 1 of the compound stock'is provided with a channel 2 having a bottom 3 and parallel sides 4, at right angles thereto. The
3" outer sides 5 are at a slight angle to the sides 4 and the sides 6 are at a slight angle to the bottom of the channel.
The part 7 of the compound stock may be shaped to provide a rectangular body porton 8 having a dovetail portion 9. The widest portion of the dovetail is equal to the width of the channel 2.
In assembling the portions 1 and 7, the
dovetail 9 is caused to fit into the bottom of the channel 2. The assembled parts are then subjected to pressure, as by drawing or rolling to cause the vertical portions of the part 1 to fit in the angle 10 of the part 7, which they will do by being bent over there- 4 into. The angle 11 of the part 1 is substantially the same as the angle 10 of the part 7 When the parts are preliminarily assembled, the ends of the rods are swaged or hammered together and may then be inserted in a die, as in the ractice of wire drawing, and drawn throug the dies, whereby the scribed the preferred form of the invention,
vertical sides of the part 1 will become deflected inwardly to such an extent, the two arts will become firmly locked together.
The method of uniting may be practised while the metal or metals are either heated or cold, and sections of various shapes may be formed, either at the time of uniting, or after the bond has been made, and will retain the same sectional ratio of metals as at the time of uniting.
Various changes and alterations will suggest itself to those skilled in the art to which this invention relates and while I have deit will be understood that I reserve the right to all changes properly falling within the sco eand spirit of the appended claims.
herefore what I claim as new and desire to secure by Letters Patent, is: 1. The method of making piston ring stock of rectangular section comprising providing a bronze member with an angular shaped dovetail and a steel member with a substantially parallel sided channel adapted to fit over said dovetail, the outer surface of said steel member being of such shape that when the side walls of said steel member are bent without substantial flowing action into engagement with the sides of said dovetail, the outer surface of said steel member without any additional substantial finishing operation forms art of the desired outer contour of the finished product.
2. The method of making piston ring stock of rectangular section comprising providing a bronze member with an angular shaped dovetail and a steel member with a substantially parallel sided channel adapted to fit over said dovetail, the outer surface of said steel member being of such shape that when the side walls of said steel member are bent without substantial flowing action into engagement with the sides of said dovetail, the outer surface of said steel member without any additional substantial finishing operation forms part of the desired outer contour of the finished product, and then cold drawing the stock.
In testimony whereof, I have hereunto 100 afiixed my signature.
