W. G. BUCK VALVE ROTATING DEViGE Filed June 5. 1918 Inga 1 5 2300070? Patented Mar. '3, 1925.

T 0 all; whom it may. concern citizen of the U11itecl States, residing/at :Fremonhinthe county of Dodge and state of Nebraska, have invented certain new and useful Improvements in :Valve-Rotating: Devices, of which-the tol-lowingnis arspecification.

Figure 3 is a section on line 33 of Fig.

Figure't is an under face view -oti the rotating mechanism, showing; the connection 7 between said mechanism and the valve stem.

"The valve illustrated comprises a vvalve valves in the stem 11 terminating ina valvehead or memr.ber.12, andrisof the usual pn'ppettypefand may be employed for controllingoeitherthe inlet or exhaust openingsof: the 1 engine. A bushing ,13 is. shown,. which. is: formed .at its =.upper end ;.with U a flange .14, notched; as A at .vide a one-wayacting clutch mechanism bel5; .andiengaging Witlr the walls of; the notch Lsaidibushing is held against rotative lmove- .A.;.sleeve :17 t1s.;provided,.which is Yformed ,iwith outwardly extendmgllugs or Lknobs l8 iWhich. travel iivitliin helical slots 19; in the bushing 13.

1 The-sleeve 17 aszwill. bei secn fromili igh 2, terminates in a, holloWfhead 20,",and on the lower ,end of said headiis an loutwardlv extending flange 21. Engaging with .tlie flange 3-21 is a cap-22 which isiseatedor ,iotherwise .iaflixed to a 1111 1 23, having; there/urea; ball- ,race24. This. arrange thesaid clutch device. .in; auhouslng located at the ,lowersend of;the waived-stein,

halls-a e.icooperates.aVith a ball race 25 in a collalp26, and {thenaces 24. an 2 1 1 11 nihearlng lace to;,i;e, ;cive suitable bearings 27;

llhe collar 26 is formed on, its; ,un der face A with an elongated recess 28,;within. ,which l li s.- a pin iorikey 2 exte ding thtoughz a opening in the valve stem. In allstandard valve constructions, this key and opening is present in the stem so that. the A rotating de- 7 vice of it the present invention can be ap- 1 plied vjtoany tormiofqvalve without any alteration therein, theikey e29 torming the sole means for securing and maintaining-allot the. rotatin parts in proper. positio'niwith respect to the stem.

Extending upward from the collar 26 is a neck 30 (see Fig. 2), and said neck, as shown, is flattened as at 31 (see Fig. 3) on one or more sides to receive a. notched disk 32. The opening through the disk is fiattened in accordance with the flattening of the neck 31, and thus the disk is at all tunes rotatable with said neck. This disk lies within the hollow head 20 of the sleeve .17, and positioned between the face of the notches in said disk and the inner wall of the hollow head are rollers 33.

Assuming the tappet to be operating to force the valve upward, the collar 26, ring 2?), cap 21, head 20, sleeve 17 and lugs 18 will be carried upward therewith. In fact, all portions of the rotating mechanism, with the exception of the bushing 13, will be moved in unison with the valve stem. By

reason of the lugs 18 traveling in the heli cal slots 19, a rotative motion in the direction of the arrow (see Fig. 3) will be imparted to the sleeve 17 and head 20. This rotative motion will act to move the rollers in such manner as to cause them to wedge between the face of the teeth of the disk 32 and the inner wall of the head 20, and thus a rotative movement will be transmitted to the disk 32, and thence to the neck 30, collar 26, and through the pin 29 to the valve stem 11, which will impart a rotating motion to the valve.

After the tappet releases, a spring 3% will tend to move all of the rotative mechanism,

except the bushing 18, together with the clutch within said chamber for imparting valve stem and valve, in a downward direction; and when moving in such direction, the sleeve 17 will be rotated in the reverse direction from that in which it was previously rotated, owing to the fact that the lugs 18 are traveling downward in the slots 19, and so on the downward movement the head 20 will be revolved in a direction reverse to that of the arrow in Fig. 3. This will tend to move the rollers 32into the position shown in Fig. 3, wherein they will be at the deepest portion of the notch in the disk 32 and will be in a non-wedging position with respect to the face of said notches. and the inner wall of the head 20. They will therefore effect no clutching engagement between the head and the disk 32, and thus on the downward movement no rotative action will be imparted to the valve stem, and it and the valve will return to seated position with a straight-line movement.

It is understood that although the head 20 is held in place by the cap 22, so that it is moved in unison with the movements ofthe valve stem, nevertheless, it has a turning movement with respect to said cap and with respect to the ring 23.

Although the device has been described with considerable particularity, it is not deemed to be limited other than may be by the terms of the appended claims.

I claim:

1. In a device of the class described, the combination of a reciprocating valve stem having a valve member thereon, a sleeve surrounding said stem and loose thereon, said sleeve terminating in a hollow head at the lower end thereof, a collar afliXed to the valve stem, and having a part thereof extending within the hollow head of the sleeve, a connection between the collar and sleeve causing them to move back and forth simultaneously as the stem reciprocates, means for imparting an oscillating rotative movement to the sleeve as it moves back and forth, and a one-way acting clutch serving to impart rotative movement fro-m the sleeve to the collar and thence to the valve stem only as a the sleeve rotates in one direction, substantially as described.

2. In combination with a reciprocating valve stem having avalve'member thereon,

a member affixed to the lower end of the stem, a member loose upon the stem and ciprocating movement to said loose member as it moves back and forth, said members being formed to provide a chamber at their point of 1uncture, and a one-way acting rotative movement from said loose member 3. In combination with a reciprocating.

valve stem having a valve member thereon, a collar aifixed to the lower end of the stem, a sleeve loosely mounted on the stem above the aifixed member, a connection between the collar and sleeve whereby they move back and forth in unison with the stem, means for imparting an oscillating reciprocating movement to the sleeve as it moves back and forth, a neck extending from said collar, a chambered head extending from said sleeve and arranged concentric with said neck and spaced away therefrom, a one-way acting clutch mechanism interposed between the neck and the interior of the head, whereby rotative movement is transmitted from said sleeve to said neck and thence through the collar to the valve stem only while the stem, collar and sleeve are moving in one direction, substantially as described.
