PISTON.
incense.
To all whom it may concern: I
Be it known that I, OYRENIUS Loser-I, a citizen of the UnitedStates, residing at Schuylkill Haven, in the county of Schuylkill and State of Pennsylvania, have in vented a new and useful- Piston, of which the following is a "specification.
This invention relates to new and/useful improvements in piston;constructions, and it is the primary object ofthe invention to provide means for increasing the life of aluminum pistons equal to that of cast pistons.
A further object of the invention is to provide means of this character which may be readily removed'and replaced,;in the event that it becomes necessary to repair the pistons.
A still further object of the invention is to provide aluminumpistons having a removable cast wear sleeve, constructed to be sprung into position around the piston to which the sleeveis attached.
A still further object of the invention is to provide a cast piston ring groove lining, to be employed in connectionwith the piston rin grooves of aluminum pistons.
ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing fromtheispirit of the invention.
Referring to the drawings:
Figure 1 illustrates a side elevational view of a piston supplied with a sleeve constructed in accordance with the present llvention.
Figure 2 illustrates an end g'elevational view of the same.
Figure 3 illustrates a longitudinal sectional view through a piston and its sleeve,
Figure 4: illustrates a longitudinal sectional viewthrough a piston and sleeve, the same illustrating a modified form of the invention.
Figure 5 illustrates view of the same.
Figure 6 illustrates a longitudinal sectional view through another modified form of sleeve securing means, and
Figure 7 illustrates an end elevational view of the same.
an end elevation al Specification of Letters Ifatent. Patented June 27, 1922. Application filed March 15, 1920. 'Sria1 No.'3G5,799.
Referring to the drawingsin detail, the
This sleeve 8 is tubular. in formation so that the same will conform. to: the contour of the p ston to which the same is applied, the sleeve being of a thickness equal to the depth-of the clearance formed between the flanges 6- and 7, so 't-h-atthe periphery of the sleeve 8 will lie in the same plane with the peripheries of the flanges 6 and 7 The sleeve 8 is formed of suitable cast material so that the same will constitute the wear su'rfaceof a piston, thereby providing a piston which is relatively light in weight but possessing the wearing qualities of the usual cast piston.
From the foregoing it is obvious that the sleeve, 8, which possess resilient qualities suflicient to permit the same to be expanded, 1s sprung into position between the flanges 6 and 7 and secured in such position by means of the flanges.
To further increase the life of the aluminum piston, the piston ring groove linings 9 are provided which are also of cast material and possessing wear resisting qualities to maintain a leak-proof connection between the piston rings and the groovesin which the. same are positioned.
These rings are preferably of the split ring type and also possessing suflicient resilient qualities to permit the same to be sprung into position, the linings being however constructed to conform to the contour of the usual piston ring grooves.
In the modified form of the invention as illustrated by Figure 4 of the drawings, the sleeve 8 is shown as positioned between the open end of the piston and the flange 9 formed substantially; intermiediatie the length of the piston, the sleeve being provided with internal screw threads 10 adapted to cooperate with the threads 11 formed exteriorly of the piston 5, adjacent the open end thereof.
It will-thus be seen that to position a sleeve of this character, it is only necessary to slide the sleeve, which is preferably tubular, over the piston until the threads 10 and 11 are brought into engagement with each other. Upon rotation of the sleeve the threads cause the sleeve to be moved along the piston body until the inner end thereof contacts with the flange 9', whereupon a binding action is set up to secure the sleeve against displacement.
By reference to Figure 6 of the drawings, a further modified form of the invention is shown, wherein the cast sleeve 10 has its inner extremity contacting with the flange 12, the opposite end thereof lying flush with the open end of the cylinder.
In this form of the invention, the cylinder is provided with internal threads as at 13' to receive the exterior threads 14: formed on the clamping ring 15, which clamping ring is also provided with an annular flange 16 adapted to contact with one extremity of the sleeve 10' to force the sleeve into close engagement with the flange 12' of the piston.
It might be further stated that these pistons as shown in the modified forms of the invention are also provided with the cast linings adapted to be positioned within the piston ring grooves in a manner similar to that shown by the preferred form of the invention as illustrated in Figure 3 of the drawings.
In view of the foregoing description, a detail description step by step of the operation of the device, is believed unnecessary.
Having thus described the invention, what is claimed as new is A piston comprising a body portion, a removable sleeve positioned on the piston, said body having ring grooves disposed adjacent to one end thereof, groove linings positioned within the groove and having portions thereof overlying portions of the periphery of the body, and said groove linings adapted to contact with rings positioned therein.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
