. 1 This invention relates to improvements in methodof forming pistonring elements of .ribbon steel.
The main objects of this invention. are:
First, to provide a, method of forming split-pis- .ton ring elements having chromium platedpcripheralcylinderwall engaging faces which enables thevery rapidlproduction of the elements and a very uniform product.
Second, to provide a methodin which. onlythe peripheral surface is plated, thereby conserving material.
: Third, to provide amethod-of forming split piston ring elements which have very long lifeeven when used under severe conditions such as in badly wo-rncylinders.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A preferred embodiment of' the invention is illustrated in the accompanying drawing, in which:
Fig. 1 is-a fragmentary sideelevation illustrating the first step of my method, namely, the coiling of a strip of ribbon steeledgewise intoa multiple coil spiral.
Fig. 2 is a fragmentary view partially in vertical section illustrating the succeeding steps, that is, the step f mounting such a multiple coil spiral in a plating bath holder and the submerging ,of,
the multiple coil spiral so mounted in a plating bath.
Fig. 3 is an enlarged fragmentary section illustratin the multiple coils after plating.
;Fig, 4 is a'fragmentary section illustrating the step of cutting the multiple. coil peripherally plated spiral into split piston ring elements.
Fig. 5 is aside view of one of the splitplst-on ring elements illustrating the relation thereto of the saw, although it willbe understoodthatthe ring elements expand under their inherent ten-- sion after they have been released from the holder.
In the practice of my method, I first form a multiple coil spiral I out of ribbon steel coiled edgewise, as is illustrated in Fig. 1. The means for coiling are not illustrated as they form no part of this invention.
I mount the multiple coil spiral upon a plating bath holder comprisin end plates 2 and 3 which are clamped upon the ends of the multiple coil spiral by means of the nut l threaded upon the end of the spindle 5, this being provided with an abutment collar 6 for the clamping member 2 Shims. (01. 204.?35.)
The holder is provided with a suspending hook I engaged with the support 8 which in practice is preferably .a current conductor. the spiral are clamped between the members 2 and 3 of the holder-in side by side relation formT ing a substantially fluid sea1-that is, they are clamped together so that there is very little opportunity or tendency: for the plating fluid to throw between the individual coils and thus plate the sides thereof. Theclamping members 2 and 3 are solid so that-theplatingfiuid is substantially excluded from the coils.
The platingbath 9- is conventionally illustrated and the loaded holder is preferably submerged inthe bath within' asleeve likeanode 50. The rings constitutethefcathode. This results in the application or depositing of a coating ll of chm miumloi-"other-desired material on the peripheries of the composite or'multiplecoil.
Afterthe platin'g the multiple coils are out longitudinally as by'mean's of a, saw l2 into individual ring elementsl3. This severing or cutting of the individual elements-is preferably done while the multiple coil is supported onthe holder, as is'illustrated; in Fig, 4, as this avoids the necessity of a separate chuckin operation for the cell. This method, including the coil forming and plating steps, may beveryrapidlyperformed, Where it is attempted to chrome plate the peripheries of split rings after the gap is cut therein, instead of before cutting the 'gap' therein as in the method of my invention herein described, the-gap must be very accurately milled and the diameter held very accurately so that when the rings are closed up the gaps. ofall the rings on the plating arbor or mandrel come togethersolidly. If one ring is alittle-largerthan others it will butt together first and holdthe-ad-jacent rings open; gassing will resultandthe platemay-be destroyed at the openings. If'certain of the rings have too much gap in comparison tothe others they naturally stand open and will gas!" My method, which includes the step of electrically plating the multiple coil spiral while in the form of a continuous integral multiple coil member, and with the individual coils thereof clamped in side by side substantially fluid sealing relation, overcomes all of these difficulties and not only results in a superior product but greatly lessens labor and time. The suspending hook I may be threaded into the collar or thrust memberfi on the spindle 5.
The apparatus illustrated is highly practical for the practicing of my method. I have not attempted to illustrate other apparatus which might be used as it is believed that the disclosure The coils. of
