CHARLES HOPPER, 0F LBS ANGELES, CALIFORNIA.
INLAY FOR REPAIR OF SCORED ENGINE-CYLINDERS AND METHOD 01E IllfilIAKINGr SAME.
Application filed January 19, 1920. Serial No.
To all whom 2'2. may concern..-
Be it known that I, CHARLES HoPPnR, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Inlays for Repair of Scored Engine-Cylinders and Methods of Making Same, of which the following is a specification.
This invention relates to an inlay, and particularly pertains to a means and method for repairing scored engine cylinders embodying cutting away the scored port-ion of the cylinder and placing an inlay of soft metal in the cutaway portion.
Heretofore inlays of the above character have been made by forming a shallow dovetail channel. This method, while effecting a temporary repair, is not durable, for the reason that the thin inlay on being subjected to wear, becomes so thin that the edges thereof turn outward and become disengaged from the walls of the channel. Furthermore, it is impractical to regrind an engine cylinder having the ordinary inlays without renewing the inlay, which is objectionable in that the renewal necessitates cutting away such quantity of material of the en gine cylinder as to weaken the latter.
It is the object of this invention to provide a construction whereby the inlay will be formed with reinforcing ribs along its edges so arranged as to securely key the inlay in place in the cylinder wall and permit considerable wear and regrinding of the inlay without destroying the same, and in which the channel for receiving the inlay will be of such shape as not to appreciably weaken the cylinder wall.
Other objects will appear hereinafter.
The means and method of carrying out the invention are illustrated in the accompanying drawings in which;
Figure 1 is a detail in section of a portion of an engine cylinder showing the score therein.
Fig. 2 is a view illustrating the manner of initially removing the score.
Fig. 3 is a detail illustrating the manner of forming the channel with inclined side walls and forming the bottom wall of the channel with grooves arranged in continuation of the side walls.
. Fig.- 4 is a detail in section showing the inlay receiving channel.
Specification of Letters Patent.
Patented Nov. 115, 1921.. 35am.
Fig. 5 is a detail illustrating the manner of placing the inlay inthe channel where an inlay strip of curved cross section is employed.
Fig. 6 is a view illustrating the inlay after being peened. v
Fig. 7, is a detail in perspective showing the preferred form of the inlay when completed.
Fig. 8 is a detail in the preferred form of the inlay strip.
In carrying out my invention, the score indicated at 9 in Fig. l is removed by cutting a channel 10 along the score by means of a vertically disposed side cutting milling tool 11, whereby the channel is formed with a fiat bottom wall 12, and parallel side walls 13; the side walls 13' extending parallel to the diameter of the cylinder.
After forming channel 10 the side cutting milling tool is disposed at an incline and lowered as shown in Fig. 3, so that when advanced along the side of the channel 10, the side Walls of the latter will be formed at an inclination and the bottom wall of the channel will be formed with a groove 14 of rectangular cross section, the bottom wall of which will extend substantially at right angles to the inclined side wall of the channel and obliquely in relation to the bottom wall of the channel. The opposite side walls of the channel are inclined in opposite directions.
The inlay 15 for filling the channel is preferably formed of arcuate cross section and of a width substantially corresponding to the width of the upper portion of the channel and of a thickness slightly in excess of the greatest depth of the channel.
A strip of the inlay metal is placed in the channel, as shown in Fig. 5, and is peened to cause it to completely fill the channel. as shown in Fig. 6. The portion of the inlay extending above the surface of the cylinder is then removed by scraping or grinding so as to finish the inlay flush with the cylinder surface, as shown in Fig. 7.
The inlay will thus be formed with oppositely inclined flanges 16 along its edges which extend into the grooves 14-, and thus serigrely key the inlay in place.
y lay are reinforced and are not liable to become displaced, and by forming the edges of the inlay with an increased thickness the outer face of the inlay may be cut away in perspective showing regrinding the cylinder without destroying the inlay.
If desired, the inlay 15 may consist of fused metal run into the channel and peened when cooled, or the metallic strip may be of any suitable shape.
I-claim: I
1. The method of building a metallic inlay in a cylinder wall consisting in forming a channel in the cylinder with'inclined side walls and a grooved bottom wall, and placing a metallic inlay in the channel thus formed with the inlay filling the grooves in the channel.
2. The method of forming a metallic inlay for cylinders consisting in forming a channel in the cylinder of rectangular cross section, cutting the sides of said channel at an inclination and forming the channel of increased depth in continuation of said side walls to form the channel with spaced grooves, and filling the channel thus formed with soft metal.
3. An inlay for cylinders, comprising a wall having a channel formed with longitudinal grooves in the bottom wall thereof, said channel having inclined side Walls terminating in the bottom of said longitudinal grooves, and a metallic filler in said channel formed with ribs on its edges extending into said grooves.
4. In an inlay for cylinders a wall having a channel formed with oppositely inclined side walls, and having spaced grooves on its bottom wall, the outer walls of which grooves are formed in continuation of the side walls of the channel, and a metallic filler in said channel having reinforcing ribs on its edges extendin into and filling the grooves in the bottom of said channel, said filler having inclined side walls conforming to and engaging the side walls of said grooves and said channel.
5. The method of building a metallic inlay in a cylinder wall consisting in forming a channel in the cylinder with a grooved bottom wall, and placing a metallic inlay in the channel with the inlay filling the grooves in the channel.
6. The method of building a metallic inlay in a cylinder wall consisting in forming a channel in the cylinder with a grooved. bot tom wall, and placing a metallic inlay in the channel with the inlay filling the grooves in the channel, the sides of the channel and the edges of the inlay being interlocked.
7. An inlay for cylinders, comprising a wall having a channel formed with grooves in its bottom wall, and a metallic filler in said channel formed with ribs extending into said grooves.
8. An inlay for cylinders, comprising a wall having a channel formed with grooves in its bottom wall, a metallic filler in said channel formed with ribs extending into said grooves, and means whereby the edges of the inlay may be anchored relative to the sides of the channel.
