@HEODORE S. PURNIS, OF ABERDEEN, SOUTH DAKOTA, ASSIGNOR TO THE K. 0. LEE & SON COMPANY, OF ABERDEEN, SOUTH DAKOTA, A CORPORATION OF SOUTH DAKOTA.
LINER FOB VALVE SEATS.
Application filed February 20, 1926, Serial No. 89,692. Renewed January 25, 1929.
This invention relates to liners for valve seats and has for its object the provision of a device which is adapted to be insertedin a recess in the intake or exhaust passage of a cylinder block after said passage has been re-bored to form the recess, the liner being adapted to be planed to provide a bevelled edge to properly seat the valve.
A further object of the invention is the provision of a liner adapted to fit a recess which has been rebored at the outer end of an inlet or exhaust passage of a' cylinder block and which liner is formed of cast iron turned slightly larger in diameter than the diameter of the rebored recess so that the liner may be forced into the recess under pressure and held firmly in place, the constant tapping of the valve when seating aiding in expanding the liner and thereby causing the liner to be retained more firmly in position.
A still further object of the invention is the provision of a liner having a sheared lower end which will facilitate the insertion of the liner in a re-bored recess at the outer end of an intake or exhaust passage in the cylinder block.
. This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a 'part of the specification; nevertheless it is to be understood that the inventionis not confined to the disclosure, being susceptibleof such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claim.
In the drawings:
Figure 1 is a vertical section of a cylinder block showing the liner, constructed according to the principles of my invention, in position.
Figure 2 is a vertical section of a cylinder block showing a modified form of the liner.
. In carrying out'my invention the wall of 45 the passage 10 in the cylinder block 11 maybe either an intake or an exhaust passage and when the valve seat has been injured to an extent where it is impossible to plane said seat to receive the valve, I re-bore the pasconform tothe shape of the liner employed for the purposeand in the construction shown in Figure 1 the recess has a vertical cylindrical portion, a horizontal base portion 13 and a small tapering portion 14 connecting the two. In this recess 12- is seated a liner 15 constructed in accordance with the principles of my invention and the liner has a greater external diameter than the diameter of the recess 12 so that the liner must be forced into the recess and be maintained by the frict onal contact between the liner and the walls of the recess and by the pressure exerted when the liner is forced into position.
" The liner has an outer cylindrical wall 16, ahorizontal base portion 17 and a tapered portion 18 adapted to-engage the tapering portion 14 of'the recess 12 while the base portion 17 ofthe liner isiseated upon the horizontal base'13'of the recess. After the liner has been forced in place it is planed along its upper inner edge as shown. at 19 to provide a seat for the valve by a planer described and claimed in my'co-pending application Serial No. 119,909, filed July 1, 1926.
The modified form of liner shown at 15 in Figure 2 is seated within a modified form of recess 12 which has an inclined base 20 extending from the outer wall of the liner to a point adjacent the inner end, leaving a very forced into the recess 12 and seat on an annular shoulder 23. The liner in this case likewise has a greater diameter than the recess so that the liner must be forced into the recess under pressure whereby the liner will be held in frictional contact within the recess. This liner is also sheared by means of a planer to form a seat 24 to receive the usual valve.
What I claim is:
A cylinder block construction having a vertical passage opening through the top of the block, said block being provided with a recess countersunk in said block at the opening of the passage, said recess having a cylindrical vertical wall with an' annular inclined bottom portion, a, liner fitted in said recess ing to the inclination of the bottom portion and of greater diameter than the diameter of of the recess and the inclined portionof the said recess whereby said liner Will be fricinner end of the liner being adapted to snugly 10 tionally held in said recess, the inner, upper engage the inclined portion of the bottom of 5 edge of the liner being sheared ofi toform a the recess.
valve seat, said liner being provided at its inner end with an inclined portion conform- THEODORE S. PURNIS.
