TOOL FOR INSERTING SPLIT SLEEVES Filed Aug. .18, 1922 W ENVENTOR ATTORNEY Patented May 5, 1925.
1 UNITED STATES .NILS ALFRED ANDERSON, 0F WOO'DMERE, NEW YORK.
TOOL FOR INSERTING SPLIT SLEEVES.
Application filed dugust 18, 1922. Serial 1T0. 582,689.
To all whom it may canoe-m:
Be it known that I, NILS ALFRED Annnns soN, a subject of the King of Sweden, and aresident of Woodmere, in the county of Nassau and State ofNew York, have invented certain new and useful Improvements in Tools For Inserting Split Sleeves, of which the following is a specification.
In certain automobiles, such as the Cadillac, the collar on the valve spindle of the engine lying below the valve spring is held in place by a sectional member or split sleeve which fits into a circumferential groove in the valve' spindle, and'over which the collar'engages, the split sleeve serving for the same purpose as acotter pin. I In such engines it is not very difiicult to remove the split sleeve but when the valves have been removed for regrinding or for any other purpose and the split sleeves have been removed it is very tedious and diflicult to replace the split sleeves by hand because of the small space for the fingers in manipulating the parts. The object of the present invention isto provide a very convenient tool to receive the members of the split sleeve and hold them while they are being inserted or placed-on the valve spindle. The
tool is of convenient size to meet the space requirements and it serves to insert the split sleeve very easily and quickly into place and it may be very easily removed after the op eration. The tool issmall, compact, and inex ensive. j a
the drawing formingpart of this application- Figure 1 is an elevation of an automobile engine valve showing the present device be ing used to insert the split sleeve,
Figure 2 is a" sectional view showing the split sleeve andwasher in place on the valve spindle,
Figure 3 is asectional view taken on the line 3-3 of Figure 2,
Figure 4 is an elevation of part of the valve spindle showing the groove for the split sleeve,
Figure 5 is a plan view of the tool with the split sleeve 1n position ready to be inand I Figure 6 is an enlarged view of one of the jaws of the tool holding one member of the split sleeve. I
In Figure 1 I have shown the parts of an automobile engine where the present tool is used. In this view 1' represents the valve 'and -2 its seat in the engine block. The valve is on the upper end of a spindle 3 and surrounding the spindle is the coiled spring 4 which closes the valve.
The lower end of this spring is compressed against thecollar 5 which is slidable on the spindle 3. The collar 5 is held from moving down on the spindle by means of the split sleeve, the latter consisting of the members 6 andfl7 of \cross sectional shape corresponding with sections of an annulus. Vertically these members taper being smaller at the to andlarger at the bottom. When placed 1n the circumferential groove 9 of .the valve spindle 3 they form substantially a frustrum of a cone, the adjacent edges of the members generally being spaced, as shown at 10. The
ore of the collar 5 is tapered as shown at 11 so that when the collar presses down on the members 6, 7 the latter will be clamped tightly against the spindle 3 and the members 6, 7 can not move up or down by reason of theshoulders 12. These parts are of standard construction in certain automobiles, the split sleeve serving as a cotter pin for 'the collar 5 but it serves to hold the latter centered. The present tool is adapted for placing the members 6, 7 in positionin the groove 9 to receive the collar 5. In Figure 1 Ihave shown an ordinary valve lifter 13 applied to lift the collar 5 while the split sleeve is being inserted.
The present tool comprises, preferably,
arms 14 and 15 hinged or pivoted together 'at 16 or at their outer ends. The arm 14 has anopening 17 through which the arm 15 passes, so that the arms cross each other at 18. On the endsopposite the pivot'16the arms are provided with jaws or sockets 19, 20 to receive and hold the members of the -jsplit ring, The jaw 20 on the arm 15 has lugs 21 extending horizontally, on which the bottom edge 22 of one of the sleeve members is adapted to rest. Toward the handle end the jaw 20 has a lug 23 to enga e one edge 24 of the sleeve member 6. t the oppositeside of the jaw'20 there is another lug 25 .to engage the other edge 26 of the sleeve member 20. The jaw 19 has similar lugs 21, 23, and 25 only they are directed oppositely in order to hold the member '7 facing the member 6. The lugs 25 are near the bottom edges of the jaws for a purpose pose is to move the aws toward each other.
When the sleeve members are inserted. in the aws 19, 20 they are held in every direc tion, except against upward displacement. In using the tool the sleeve members are placed in the respective jaws, and while the collar is held raised by the valve lifter 13, as shown in Figure l, the tool is moved up to the spindle 3 and the handles 14, 15 are pressed toward each other-to separate the jaws 19, 20, and the tool is moved until the sleeve members 6, 7 straddle the grooved portion 9 of the spindle and then the pressure on the arms 14, 15 is released. The spring 27 will press the jaws toward each other, pressing. the members 6, 7 against the spindle 3. The valve lifter 13 is released to allow the collar 5 to move down over the top of the sleeve members 6, 7 whereupon the latter require no further holding in position. The tool is then pressed downwardly until the lugs pass below the bottom edges of the members 6, 7 and there is just room enough for this before the tool strikes the nut 28. The tool is then drawn laterally away from the spindle leaving the sleeve in position.
The tool may be used to remove the sleeve but this is not necessary, the only difiiculty being that of inserting the sleeve.
Having described my invention what I claim is:
1. A tool for the purpose set forth comprising members forming a handle and aws carried thereby and movable toward and from each other, said jaws each having curved sockets including a bottom support and lugs for engaging over the edges of. a
split sleeve whereby each jaw may separately carry separate sections of the split sleeve to permit the split sleeve sections to be applied laterally against a grooved spindle by said jaws.
2. A tool for the purpose set forth, comprising members forming a handle, andjaws carried thereby and movable toward and from. each other, said 'jaws each having curved sockets includinga bottom support and lugs for engaging over the edges of a split sleeve section whereby each-jaw may separately carry separate sections of the split sleeve to permit the split sleeve sections to be applied laterally against a grooved spindle by said aws and spring means for normally pressing said jaws toward each other.
3. A tool for the purpose set forth comprising arms hinged together at one end and crossing each other near their opposite ends, jaws on said latter ends of said arms, each jaw having a semi-circular socket for receiving a split sleeve member from the top and including a bottom member on which the sleeve member is supported and .inturned lugs for the opposite edges of the sleeve member, said jaws being adapted tobe released from said sleeve members when the same have been placed on the valve spindle, by a downward movement of the tool in relation thereto.
4:. A valve stem key holder comprising a segmental key holding member having a vertical side wall terminating at the base thereof in an inwardly extending seat, and having means for holding the key in place on said seat, said member being open at the top of said vertical wall to permit the insertion or removal of a key.
5. A valve stem key holder comprising a pair of connected key holding members, each having a pair of opposed vertically and inwardly extending projections and an inwardly projecting base extending between each pair of projections.
6. A valve stem key holder comprising resilient means for gripping the valve keys -on a valve stem, said holder having means adapted to be engaged by the valve spring retainer for ejecting said holder.
