PISTON.
Application filed November 10, 1924. Serial No. '148,854.
This invention relates to a piston for internal combustion engines, and specifically adapted to be cast in gray iron, and to have the lightest possible weight consistent with the requisite strength.
A further object of this invention is to facilitate the lubrication of the walls, and the final object is to dissipate the heat from the head of the piston down into the skirt. Figure 1 shows a cross sectional elevation on the plane 1-1 of Figure 2.
Figure 2 shows 'a sectional plan view on the plane 2-2 of F igure 1.
Figure 3 shows a sectional elevation on the plane 3-'-3 of Figure 2.
In the drawings, A indicates the head of the piston, B and C the wrist pin bosses.
D D D D are the ribs supporting the piston head A, the ribs terminating in the bosses B and C. E indicates the upper portion of the head provided with the usual number of piston ring grooves.
F F indicate the side wall hearing strips connecting thenpper portion of the cylindrical skirt E with the lower portion G.
The lower portion Gr is provided with two a'nnular stifl'ening rings H forming a channel section. K K are the webs connecting the bosses B C to the lower portion of the ski't G, but the major portion of the side thrust is transnitted from the bosses B C to the hearing strip F F through the webs J J.
These webs J J flare from the side wall bearing strips to the bosses, thus giving a truss Construction which provides the requisite strcngth so that the bearing strips will not be deflected either when they are machined or when the pistons are in use.
The ribs D D are preferably arranged to flare from the bosses to the piston head, whereby the piston head is supported at four points or strips, the purpose being to enable the lightest possible Construction to be used.
body of the piston.. This Construction e therefore gives a less expansion to the bearing strips %F F despite {the fact that they are integrally connected with the head A E of the piston, which is at a much hi her temperature than that of the cylind er bore in which the piston reciprocates,
What I claim is 1. In a skeleton piston, in combination, a. head, an upper skirt connected thereto provided with the usual number of piston rin grooves, a lower skirt, side hearing sur aces connecting the upper and lower skirts, connecting rod bosses, four webs extending flaringly from said bosses to said piston head and substantially horizontal webs. extending flaringly from the central portion of said hearing surfaces to said bosses.
2. A skeleton piston, oonsisting of a piston head, a skirt comprising an upper portion provided With the usual number of piston ring grooves, a lower portion, bearing strips connecting the upper and lower portion, connecting rod bosses, webs projecting horizontally from the bosses to the hearing strips, four stifl'ening webs extending flaringly from said bosses to said piston head, wlhereby the piston head is supported in four p aces.
In testimony whereof I aflix my signature.
DE Fo Esr w. CANDLER.
