POPPEI VALVE.

Application filed June 7,

This invention relates to a poppet valve for use in connection with internal combustion motors, but it is to he understood that a valve in accordance with this invention can be employed for any purposes for which it is found applicable, and the invention has for its object to increase the duration of the eliiciency period of the valve and to further provide, in a manner as hereinafter set forth, a' valve of such class capable of being turned to an extent, each time it is lifted, to insureeven wear at all points of contact thereof with its seat, whereby it will operate eiiiciently for longer periods than it its posit was not successively changed on the application of the lift thereto during the operation of themotor.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a poppet valve for the purpose referred to, which is simple in its construction and arrangenient, stron durable, thoroughly ellicient in its use, readily installed with re spect to the motor, and comparativeh inexpensive to manufacture.

lVith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a fragmentary view, in section, of an internal combustion motor showing the adaptation therewith of a poppet valve constructed in accordance with this invention.

Figure 2 is an elevation of the valvular element.

Figure 3 is a vertical sectional View of a, washer member.

Figure 41 is an elevation, partly in section of a combined coupling and shifting element interposed between the valvular element or member 2 d lifting means for the valve.

Refer ig to the drawings in detail 1 denotes a valve seat for poppet valves, 2 a cam shaft, 3 a cam carried by the latter, a valve litter of tubular form and flanged at its 1926: Serial No: 114,370.

lower end as at 5, 6 .a bushing for the lifter at, 7 a combined guide and bushing for the poppet valve stem and 8 a" part of a housing or motor head and through which extends the combined guide and bushing" 7. The foregoing elements are of known construction and term elements of an internal combustion motor and are illustrated to show the adaptation therewith of a poppet valve constructed in accordance with this invention. 7

The valve head is indicated at 9' and-its stem at 10, and the latter is oi appropriate *th and has its lower terminal portion foirned of a peripherally threaded part 11 and a polygonal shaped part 12. The threaded part- 11 is arranged above the polygonal shaped part 12 and said threaded part 11 is formed with a diametrically disposed slot 13 preferably of rectangular form.

Threadably engaging the part 11 of the stem 10 is a support 1 1-, in the form of a not having a polygonal shaped edge and said nut. 1%. is formed with an opening 15 registering with the slot 13, and extending therethrough is a cotter pin 16 torretaining the nut l i from revolving with respect to the stem 10. Mounted on the support 1 1 and surround ing' the stem 10 is a cup-shaped washer member 17 formed with a vertically disposed sleeve 18 which extends upwardly from the body of the washer member 17. The lower lace of the washer member 17 is provic ed an annular boss 19 which seats on the nut 14. The stem of the valve extends through the combined bushing and guide therefor and also through the washer member 17. The portion 8 cat the housing or engine head or block has a depending sleeve or collar 19 which surrounds the combined guide and bushing T, l at the latter depends below the collar or sleeve 19. Interposed between the part 8 of the housing or engine head or block and the washer member 17, as well as surrounding the sleeve or collar 19 is a controlling spring 20 acting against the washer member 17 for the purpose of normally maintaining the valve head against its seat 1. The washer member 17 is vertically movable with the poppet valve when the latter is lifted, but the stem of said valve can revolve within the sleeve 18 of the washer member 17. The spring 20 acts to shift the washer member 17 downwardly and which in turn carries the poppet valve therewith so that the valve head 9 will engage the seat 1.

Threadably engaging in the upper end of a lifter 4, is a vertically disposed stud 21, having its head 22 formed with a polygonal shaped socket 23, which opens at the top of said head 22. The said socket 23 corresponds in contour to the shape of the part 12 of the stem 10 and said part 12 is seated'in said socket 23 and by this arrangement when the lifter 4 is revolved the poppet valve willbe carried therewith. Carried by the stud 21' is an adjusting nut 24: for the purpose of adj ustably supporting the head 23 at varying distances with respect to the upper end of the lifter 4:. In other words the nut 24 is provided for locking the stud at any desired height for proper clearance between the valve stem and lifter 4. The head 22 of the stud 21 is formed with an opening for drainage of oil.

The arrangement and construction of parts as hereinbefore referred to. will provide for the valve head to turn enough each time the valve ,is lifted, to insure even wear at all pointsof contact of the valve head with the valve seat and by such construction. operation and arrangement it will provide for the valve to operate efiiciently for a longer time than it would if the valve head did not change its position, or in other words the construction and arrangement of parts will provide for a turning motion of the valve head on each lift of the valve.

It is thought the many advantages of a poppet valve construction, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.

lVhat I claim is:

1. In a valvular means for internal combustion motors a spring controlled poppet valve having the lower portion of its stem of polygonal contour, and means for intermittently lifting the valve, said means provided with a polygonal shaped socket re ceiving said polygonal shaped end of the stem to provide for turning or movement of the valve on the lift thereof.

2. In a valvular means for internal combustion engines, a spring controlled poppet valve including a stem having a polygonal shaped part, a washer member for confining the controlling spring for the valve, said member slidably mounted on said stem, a washer member support bodily carried by said stem, a revolublevalve lifter device provided with means for receiving said part to cause the turning of the valve on the lift thereof, said means being lengthwise adjustable.

8. In a valvular means for internal combastion engines, a spring controlled poppet valve including a stem having a polygonal shaped part, a washer member for confin ing the controlling spring for the valve, said members slidably mounted on said stem, awasher member support bodily carried by said stem, a revoluble valve lifter, and a vertically adjustable stud bodily carried by the lifter and formed with a polygonal shaped socket to receive said part to cause the turning of the valve on the lift thereof.

In testimony Whereof,,I affix my signature hereto.
