UNI/'reo stares METHOD OF BALANCING'IIS'DONS.
Application filed July 7,
This invention relates to engines and has among its objects to provide a novel means andmethod for balancingthe pistons of the engine-- In the present manufacture of a multicylinder internal combustion engine, it is custon'iary to balance the weights ofthe pistons operating inthe cylinders by removing sufficient metal-from thepistons in order to equa-lizethe weights of all the pistons.
My invention provides an improved method and means for balancing the pistons of a1. multieylinder; engine which consists in providing a1. series of weights successively Varying in. any desired increment. K the weights being adapted to be readily and selectively attachedfto the pistons in order to equalize the piston weights.
lV-ith these andfothery objects in View, the
'invention' resides in the novel features of construct-ion andi combination and arrangementsof parts as more fully hereinafter dcscribed and claimed.
Referring to the drawings in which like reference characters indicate corresponding parts;
Figure 1 is a side View of a. piston partly broken away to Ashow one of my spring rings; y
Figure 2 is a bottom pla-n view of the piston with a portion of the skirt broken away to show the spring ring; and
Figure 3 is a View showing in cross section a series of spring rings. Y
In the drawings reference character l0 represents a piston which may in general, be' of the usual or other preferred construction employed for use in an engine preferably of the multi-cylinder type. The piston may be provided with suitable means such as an annular groove ll wit-hin the skirt l2 and preferably adjacent the lower portion thereof, this groove being adapted to selectively receive any number of weight members which. for convenience. may be in the nature of split rings 13, 14 and l5 as shown in Fig ure These rings may be formed of' a resilient material such as wire and preferably vary in weight by a predetermined increment such, for example, as one-eighth of an ounce.
The pistons after being completely machined and fitted to the cylinders, are weighed and are then increased in weight to a predetermined standard by adding a ring of sufficientweight. It' it is desi-red to add 19252 Serial N0.y 41,997.
a weight in betweenthat of the,twonearestvr rin the hearien may. be used andra' portion of-the wire cut ott', or a seeond'series-ofrings may be employed varying in increments--of weight in between the weights of the first series. The resiliency of the rings permits'-v ready application; to the piston annular groove where they will be securely heldin place due tothe resilience of' the rings.
Various methods of balancing the-pistons within Ythe scope of my invention will be readily apparent. For example, ally of; the pistons may be brought up :to theweight of the heaviest .piston of a multi-cylinder#enginek or all of the pistons may be machined slightly underweight and all brought@ up'to the predetermined standard weight;
lVhile it .is believed that from theA fore- ;oin descrip tion; the nature and: advantage ot my invention will he readily understood, l desire to have it.v understood: that I? do not` limit' n'iyselt to what is herein shownand described and that such changes maybe resorted to when desired as fallv within; the scope ofthe Claims.
That l claim as my inventi'onis:y
l. The process ot producing apiston having a predetermined standard'y weight which consists in forming the piston below the desired weight, forming an engageable member on the piston adapted to support a weight member and then engaging with the said engageable member a weight member of Sullicient mass to bring the piston up to the desired standard weight.
Q; TheV process of producing a piston of a predetermined standard weight which consists in forming the piston below the desired weight, forming a socket in the piston, and then mounting in the socket a weight of sulficient mass to bring the piston up to the desired` standard weight.
The process of producing a plurality of pistons of equal standard weight which consists in forming each ot the said pistons below the desired standard weight, forming an engageable part on each piston for engagement in by a weight, forming a series of weights independently engageable with the said engageable part and varying in accordance with a predetermined increment and then engaging in the engageable part of each piston that weight of the series which is suticient to bring the piston up to the desired standard weight.
4. The process of producing a plurality of pistons of equal standard Weight which consists in forming each ot the said pistons below t-he desired standard Weight, forming a groove in each piston, forming a series of spring rings varying in Weight in accordance with a predetermined increment, and. then mounting in the groove ot' each piston that ring ot the series which has mass sntlioient to bring the piston up to the desired standard Weight. 7
5. The method ot balancing a plurality of pistons for use in a multi-oylinder engine consisting in machining and Weighing the pif-'tons and then adding one. of a series ot spring rings .'arying in weightto one or more ot the pistons in order to equalize the weights ot' all ot' the pistons.
(i. rthe combination with a piston having a portion modified tor engagement with a weight member, ot a Weight member' automatically engageable with said portion.
7. The combination with a piston, ot means on the piston adapted tor engagement With a weight member, and a series ot Weight members whose weights vary in accordance with a predetermined increment, each ol the said Weight members being adapted for unassisted engagement with the said engaging means.
rPhe combination 'with a piston Whose Weight is below a desired predetermined 9. In con'ibination with a piston formed with an annulargroove7 a series of spring rings adapted for engagement in said groove, said rings varying in their weights according to a predetermined increment.
l0. .ln combination With a piston formed with an annular groove, a series of Weight members adapted for engagement in said groove, said weight members Varying in their Weights according to a predetermined increment.
il. ln combination with a piston 'lormed with an annular' groove, a series ot rings adapted iter engagement in said groove, said rings .farying in their weights according to a predetermined increment.
l2. In combination, a piston and a series ol" annular Weight members, said piston being provided with means accommodating Selective attachment ot' said members.
13. rthe combination With a piston having means accommodating selective attachment oi one ot a series ot Weight members Whose weights vary in accordance With a predetermined increment, of a series of resilient weight members of varying weight adapted tor attachment to the piston.
let. The combination with a piston, of a series of expansible Weight members adapted t'or selective attachment to the piston tor bringiiig the weight ot the piston up to a predetermined value, said Weight members adapted to be expanded into clamping engagement with the piston.
in testimony whereof I attiX my signature.
