Specification of Letters Patent.
Patented Sept. 3, 1918.
To all whom it may concern: 7
Be it known that we, JOHN HARTLAND Bronms' and BENJAMIN BELLINGHAM, SllbJGOtS of the King of Great Britain, residinget Saltley, Birmingham, England, have mvented certain new and useful Improvements in Methods of Producing Piston-Binge, of which the following is a specification.
This invention relates to piston rmgsfor packing the pistons of internal combustion,
steam .and other engines, pumps and the like, said rings being of that type which are sud rovided upon their peripheries with a fac- 1 mg of anti-friction metal which makes contact with the cylinder well, thus reducing friction and wear to a minimum.
The object of the present invention is to apply the anti-friction metal to the iron or steel ring so that a true molecular cohesion is attained between the said facing and the ring,-thus allowing of free contraction and expansion of the ring without breaklng or separation of the anti-friction facing, and the latter being secured to the ring solely by its adhesion, wlthout the use of dovetail interlocking'parts or' other special securing means. v
The invention'eonsis'ts in first timing the peripheral surface of the ring, such tinconsisting in applying a ux to the surface and then coating this surface with tin, the tin being melted by heat and spread over the surface by a hot iron or other appropriate means; and then applying the anti-friction metal (which contains a proportion of tin) to the tinned surface by castin it thereon or b dip in the ring, the an ti-friction metal b eing, by %his means, fixed to the ring.
Figure 1 of the accompanying drawings is a section through a piston ring having an anti-friction facingin accordance with this invention.
Fig. 2 represents a transverse section through the ring.
Fig. 3 shows a modification.
' As shown in Figs. 1 and 2 the body part of the piston ring consists o a s lit sprin ring a made of cast iron or stee as usua Whl e applied to the outer surface or periphery of this cast iron or steel body isa layer or faci b of a suitable anti friction or white meta (containing a proportion of tin) which thus bears against the walls of V the cylinder in which the piston works. I
peripheral surface is first coated wi tin. This tinning operation consists in a plying a flux to the surface and then a sma l quantity of tin is melted and spread over the said surface b a hot iron or other appropriate means. been thus tinned the anti-friction metal is cast on to it in a mold, or the anti-friction metal may be applied by successive dipping operations, the ring being rotated so that its periphery moves wlthin a bath of the molten metal, which adheres to the said periphery, the layer increasing in thickness with each successive rotation. Preferably a current of cold air is arranged to pla upon the deposited metal as it leaves the bath.
With either process the anti-friction metal is fixed to and is in molecular cohesion with the ring and is thus inseparable therefrom.
The anti-friction facing b is preferably reduced in thickness towardthe ends of the is shown in 3, in addition to the anti-friction metal eing applied to the periphery of the ring, as at b, it may also be applied to the lateral faces, as at 6 these faces havin previously been prepared by tinning as a ove described. The friction between the lateral faces of the ring and the sides of the groove in the piston is thus reduced.
Having fully described our invention, What We desire to claim. and secure by Letters Patent is 1. A method of producing a piston ring consisting in applylng a flux to the peripheral surface of a split cast-iron or steel ring, spreading a thin coating of tin over the surface by the aid of heat, and applyin to the said tinned surface a layer of anti-iii metal containing tin while in a molten state so as to adhere to the said surface.
