VALVE-SPRING GUIDE AND RETAINER.
Specification of Letters Patent.
Patented May 9, 191%.
Application filed April 23, 1914, Serial No. 834,003. Renewed January 24, 1916. Serial No. 74,060.
1 b all whom it may concern Be it known that I, LUTHER J. STRAIT, a citizen of the United States, residing at Humboldt, in the county of Humboldt and State of Iowa, have invented a new and useful Valve-Spring Guide and Retainer, of which the following is a specification.
This invention relates to a guide and retainer for valve springs to be used on the intake and exhaust valves of internal combustion engines.
An object of the present invention is to provide a device which will prevent the spring of the valve from shifting with-respect to the valve stem, and so arranged as not to interfere with the proper workings of the valve.
A further object is to provide a spring guide, preventing the transverse shifting of the spring with relation to the valve stem and which guide extends down over and houses the spring holding pin.
Another object is to provide a spring guide which will present a considerable and easily gripped area so that the valve spring may be raised for the removal of the pin and the subsequent removal of the valve.
A further object is to provide a guide and retainer for valve springs which includes an elongated sleeve closely engaging the valve stem, to which sleeve is secured a member receiving the valve spring therein. The large area of contact between the sleeve and valve stem prevents the shifting of the said member and thus holds the spring in proper position.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.
In the drawings accompanylng this specification and forming a part thereof, the preferred embodiment of my invention isillustrated, in which:
Figure 1 is a diagrammatic view of a valve and cooperating parts with my improved spring retainer applied thereto. Fig. 2 is an enlarged and sectional view of the spring retainer and fragmentally lllustrating the valve stem and the valve sprlng.
Fig. 3 is a cross sectional view taken on the l ne 8-3 of Fig. 2. Fig. 4: is a cross sectional view taken on the line H of Fig. 2.
Referring to the drawings in which similar reference numerals designate correspondlng parts throughout the several views, a valve chamber 5 is provided with the puppet valve 6 and upon the stem 7 of which latter is positioned my novel valve spring guide and retainer. The foregoing generally illustrates the relative position of the valve spring guide and retainer and the parts with which it cooperates.
The valve spring 8 being considerably larger than the stem 7 tends to shift relative thereto and which interferes with the proper working of the valve, resulting from the line of thrust extending angularly with relation to the valve stem. This causes the valve to stick with a consequential miss fire of the engine and loss of power and efliciency. My present device overcomes these objections in a novel manner, which is accomplished by the provision of an elongated sleeve 11 to the lower extremity of which, is formed the base 12.
The outlying base 12 is provided with the annular groove 13 which provides a spring receiving and retaining receptacle. The rec-eptacle is concentric with but removed a distance from the valve stem and receives the end convolution of the spring coil therein. The annular groove is connected to the sleeve of the convex outstanding flange 14 which binds upon its lower side the pin receiving receptacle 15. Thus the outstanding base provides an outlying and annular groove upon its upper side and the central pin receiving receptacle upon its lower or under surface.
The valve stem 7 is provided with the usual pin 9 extending through the aperture 10 therein, which holds the spring retainer in proper position. The spring retainer fits down over and houses the pin therein, as illustrated in Fig. 2 and thus serves as an abutment for the lower extremity of the compression and coiled valve spring. The spring retainer while forming a retension guide for the spring preventing its transverse shifting, also presents an easily gripped device, thus providing for the easy raising of the valve spring, such as is necessary prior to the removing of the pin and the subsequental removal of the valve. The spring retainer results in a straight line thrust upon the valve stem, transmitted thereto through the intervention of the pin 9, which pin 9 it is to be noted is held in place with relation to the valve stem by the side walls of the pin receiving receptacle15.'
Particular attention is called to the snug manner in which the elongated sleeve 11 receives the valve stem 7 therethrough. The large area of contact between the sleeve and valve stem holds the valve spring receiving receptacle at right angles to the valve stem and prevents it shifting from such position. This insures that the spring will always remain in proper relation with respect to the valve stem and thus eliminates a side thrust or the assumption of an angular disposition of the spring.
Having thus fully described my invention, What I claim is The combination with a valve stem, of a sleeve thereon, an annular flange integral With the lower end portion of the sleeve and provided, in its lower face, with a circular depression and, in its upper face, With an annular channel, a coiled spring extending around the stem and having its lower convolution seated in the groove, the depth of the groove being greater than the diameter of the material constituting the lower convolution, and a supporting pin extending diametrically through the stem and having its terminals seated in the circular depression in the flange.
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
