GUIDE MEANS FOR NON ROTATABLE VALVE LIFTERS Filed Oct. 30, 1956 Edward. lskenderian,
INVENTOR.
AGENT.
- shown, since they are well United States Patent GUIDE lVIEAlN' S FOR NON ROTATABLE VALVE LIFTERS Edward Iskenderian, Inglewood, Calif. Application October 30, 1956, Serial No. 619,311 3 Claims. (Cl. 123-90) Objects of invention The object of this invention is to replace rotating mechanical or hydraulic valve lifters with non-rotating valve lifters, in internal combustion engines, such as used in motor vehicles when the standard camshaft is replaced with a special high lift racing cam, such as furnished by the inventor. Non-rotation of the lifters is necessary when the lifters are provided with rollers such as disclosed herein, or when the lifters are provided with a cam-like lifter face to cooperate with the camshaft in controlling the valve lift. Since such last mentioned lifters are well known in the art it is not deemed necessary to show such a configuration.
A further object of this invention is to provide such lifters that can be installed by anyone without the use of special tools or doing any machine work. All prior art non-rotating replacement lifters known to be in use do require some machine work or use separate parts that are not a part of the lifter assembly, for example such as disclosed in my copending application Serial Number 567,010, filed Feb. 21, 1956. Since racing camshafts are usually installed by the car owner it is very important that the valve lifters furnished with the camshaft may be mounted without special skill or tools.
For a more complete understanding of my invention consult the drawings and the following description, wherein:
Fig. 1 shows a pair of lifter assemblies installed in a section of an engine 10. Both lifters are in their low position, such as when both valves are closed, the rollers 2 being in a position to contact a camshaft which is not known and form no part of this invention. The upper end of the right hand lifter is in section to show how an apertured cup is installed in the top to carry a valve lifter rod. The aperture is to admit engine oil to the end of the rod resting in the cup.
Fig. 2 is a view of a single litter and roller assembly, the cup being omitted. The lifter is apertured to admit oil therein. may be omitted if desired.
Fig. 3 is a cross section of Fig. 2 showing aperture 4 therethrough to receive the guide members shown in Figs. 5 and 6.
Fig. 4 is a view of the lifter rod cup as seen in Fig. 1.
Figs. 5 and 6 are views of the guide members shown in the assembly of Fig. 1.
Fig. 7 is a view of the male guide member 6b, showing a portion cut away at 7 to fit in the aperture 4 which is sized to fit the reduced portion at the end of the guide member at 7.
Fig. 8 is a view of the complete assembly of the guide members, with the member 6b shown in broken lines.
Fig. 9 is a top plan view of an assembly of parts 6. 6a and 6b.
Description of the parts As shown in the drawings, the means to prevent the lifters from rotating comprises two off-set metal stampings and one flat member 6b. Member 6 has a square-like portion and a key-like portion, olf-set relative to each other an amount equal to half the thickness of the male member 6b. Member 6a has a square-like portion similar to 6, and is oil-set a like amount. The other portion is 2,816,988 Patented Aug. 12, 1958 the key-like portion of 6 and has a reduced portion as at 7 to fit in the aperture 4. The aperture 4 in one wall of the lifter is sized to permit the full width of the members 6 and 6b to pass through it so the reduced end can be inserted in the aperture in the opposite side wall when they are installed as seen in Fig. 1. The ends of the guide members can be staked, welded or otherwise secured in the lifter if desired. The apertures 8 and 8a are to admit engine oil to the guide members.
The lifters are of tubular construction as seen in Fig. 3. The apertures in each wall numbered 3 and 5 are for admitting oil to a cup-like member 12 with an oil orifice 13 mounted in the upper end of the lifter to provide an oil flow path to a litter rod 11, as seen in Fig. 1, the rod 11 being no part of the invention. Each lifter is provided with a roller 2 mounted in the lower end to contact a camshaft, not shown, since they are well known in the art. The small apertures 5 may be omitted if desired, and the lower end of the lifter may be provided with a camlike face instead of the roller if desired. Since it is old to provide lifters with a cam-like face it is not deemed necessary to show an To assemble the guides the member 6 is pressed in the aperture in member 6a as seen in Fig. 8, and the assembly positioned in a lifter as seen in the left of Fig. 1, the member 6b being positioned in a lifter as seen in the right of Fig. 1. As clearly shown, when the member 6b is positioned between the spaced members 6 and 6a either member including a lifter can move vertically or laterally independently. The dotted line in Fig. 1 shows the left hand member up while the right member remains down. Lateral movement is provided to accommodate various spacing of the lifter bores in the engines. The width of the guides is suflicient to permit maximum valve lift without separation of the guides.
While I have described my invention in considerable detail, it is not my intention to limit it to the specific configuration disclosed, since it is quite obvious some changes could be made without departing from the spirit of the invention.
What I claim is:
1. A pair of tubular members having associated releasable guide means, the tubular members being spaced apart, and at least a portion of the said guide means being attached to each tubular member, the said guide means having means to permit vertical and lateral movement without permitting rotation of one member relative to the other, each tubular member having a roller attached to one end and having an aperture spaced from the roller, a single piece guide member carried in the aperture in one guide member, and a two piece guide member carried in the aperture in the other of said pair of tubular members with spaced apart portions extending laterally outside of its associated tubular member, the first of said guide means extending laterally outside of its associated tubular member and positioned between the spaced apart portions of the two piece guide member and freely slidable therein when the tubular members are spaced apart a predetermined distance.
2. A valve guide means as defined in claim 1, wherein each tubular member carries a cup-"like member on one end provided with an aperture in communication with the inside of the tubular member, each tubular member being provided with at least one aperture adjacent the end that carries the roller.
3. A valve guide means as defined in claim 2, wherein the spaced apart portions of the second mentioned guide means are provided with an aperture.
