Q By Wm A llorney Patented Feb. 21, 1933 UNITED STATES STEPHEN ERNEST MEYER, ;OF.HAYDEN, ARIZONA rrsrou cousrntrcrron Application filed March 30, 1931, Serial No. 526,466; Renewed July 12,1982.
This invention appertains to new and use ful improvements in piston constructions especially adapted for use in internal combustion engines, compressors, vacuum pumps,
Q and in fact other types of pumps and engines.
The principal object of this invention is to provide a piston with novel packing means which will be more efiicient and durable than packing means now in use in this capacity.
19 Other important objects and advantages of the invention will become apparent to the reader of the following specification. In the drawings Figure 1 represents a side elevational view 15 of the novel piston.
Fig. 2 represents a top plan view of the piston.
Fig. 3 represents a fragmentary side elevational view of the upper plate.
Fig. 4 represents a top plan view of one of the packing units.
Fig. 5 represents a side elevational View of one of the sections of one of the packing units.
Fig. 6 represents a fragmentary detailed sectional view through the assembled piston.
Fig. 7 represents a fragmentary perspective view of one of the packing unit sections.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the usual apron portion of a piston which is provided with the closed head portion 6. Numeral 7 represents the usual connecting rod which is attached to the piston in the usual conventional manner.
In further carrying out the invention, a pair of packing units denoted by numeral 88, are arranged upon the head 6 and upon the packing units 88 and being smaller in diameter than the said packing unit is the clamp plate 9. 7
Now referring to Fig. 4, it can be seen that either one of the packing units 8 consists of a pair of semi-circular sections 1010, each constructed identically. At the straight edge portion of each section 10 is a notch 11 adjacent one end and a tongue 12 adjacent the opposite end, the tongues being engaged in the notches 11 when the sections are asgambled together as in the manner shown in 8 Each of the sections 10 10 is provided at its straight edge portion with a pair of rec- M tangular cu out portions or indentures 1313 in each of which is a pair of teats 1i1i: which act as guides for the adjacent ends of a pair of springs 15. Y
As can be clearly seen in Fig. 4, a notch 16 is provided in the straight edge portion of each section 10 and between the cut-out portion 1318, so that when the sections 1010 are assembled, a square opening 17 is provided for the reception of the polygonal-shaped shank 18 which projects from the head 19. This head 19 engages into a centrally located opening of the plate 9, and project openings 17 of the packing units 88. The shank 18 is provided with a threaded and reduced portion 20, which depends thru the head portion 6 of the piston construction, and has a nut 21 engaged thereon for securing the plate 9 in position over one of these units 88, which are arranged, so that the sections 10 of the upper units are disposed at right angles to the sections 10 of the lower units, and obviously the spring 15 tends to urge the sections outwardly to impinge against the wall of the cylinder in which the piston operates.
Nhile the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials, may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having thus described my invention, what I claim as new is 1. A piston construction comprising a cylindrical body having an opening through the top thereof, a disk constructed of a pair of semi-circular sections each section provided at its straight edge portion with indentures, compressible springs interposed between the sections and bearing into the indentures, said sections each being provided with projections in the indentures to engage into the corresponding end convolutions of the springs to prevent displacement thereof, the straight edge portions of the sections being provided with inwardl extending polygonal shaped openings w ioh register when the sections are assembled, and securing means provided with a polygonal portion for disposition through the polygonal shaped openings in the sections and through the said opening in the top of the piston body.
2. Arpiston construction comprising a cylindrical body having an opening through the top thereof, a disk constructed of a pair of semi-circular sections each section rovided' at its strai ht edge portion with in entures, compressib e springs interposed between the sections andbearing into the indentures, said sections being each provided with projections in the indenturesvo engage into the corresponding end convolutions of the springs to prevent displacement thereof, the strai ht edge portions of the sections being rovi ed with inwardly extending polygona shaped ings which register when the sections are assembled, and securing means rovided with a polygonal portion for disposition through the po y onal shapedopenings in the sections an through the said opening in the top of the piston body, and tongue and notch oonnoctions between the sections at the straight edge portions thereof.
In testimony whereof I aflix my signature.
STEPHEN ERNEST MEYER.
