DARIUS WILOOX, OF MECHANIOSBURG, PENNSYLVANIA.
FIFTH-WHEEL.
SPECIFICATION forming part of Letters Patent No. 523,252, dated July 17, 189 4.
Application filed January 2, 1894:. Serial No. 495.333. (No model.) I
T at whom it may concern.-
Be it known that I, DARIUS WILcoX, a citizenof the United States, residing at Mechan- 1csburg,in the cou ntyof Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Fifth-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to improve the construction of fifth Wheels, so that rattling will be prevented, in a simple manner which will not add to the cost of construction, and which will be thoroughly durable in use, the supplying of new parts after a year or two of wear being rendered wholly unnecessary.
With this end in view I have devised the novel fifth wheel which I will now describe referring by numbers to, the accompanying drawings forming part of this specification, in which-- Figure 1 is a plan view of a fifth wheel showing the application thereto of my novel improvement; Fig. 2, a rear elevation corresponding with Fig. 1, illustrating one form in which I have carried my invention into effect; Fig. 3, a section on an enlarged scale on the line w a: in Fig. 2, the spring appearing in end elevation; Fig. 6 asimilar section on the line 'y y in Fig. 5 the spring being in section. Figs. 4 and 7 are plan views on an enlarged scale of two forms of spring detached; Fig. 5 a rear elevation on an enlarged scale illustrating another form in which I have carried my invention into effect, and Fig. 8 is a perspective of the cross piece used in one form, detached.
1 denotes the upper circle of the fifth wheel which is provided with the usual lugs 2 for the attachment of the reach, and 3, the lower circle of the fifth wheel.
4 denotes a yoke, ordinarily U shaped as shown, which passes on opposite sides of the fifth Wheel and is provided with holes 5 through the ends thereof and with a hole 6 through the center thereof. The upper circle is rigidly secured to the yoke, as by a bolt or rivet 7 which passes through the upper circle and through hole 6 in the yoke. The lower circle moves freely between the sides of the yoke but is held constantlyin engagement with the upper circle so that rattling is wholly prevented by means of a spring 8 which may be made as shown in Figs. 1 to 4 inclusive or as shownin Figs. 5 to 7 inclusive.
In Figs. 3 and i the spring is shown as provided with lugs 9 on opposite sides at the center and as secured to the yoke by bolts 10 which pass through said lugs and through holes 5. The ends of the spring are curved in the horizontal planeto correspond with p the curvature of the fifth wheel and are suit ably curved in the vertical plane so that the arms thereof which are specifically designated by 11 bear upon the lower circle holding it constantly in contact with the upper circle.
In the form illustrated in Figs. 5 to 8 inclusive, lugs 9 upon the spring are dispensed with, and the spring is retained in place by a cross piece 12 through which bolts 10 pass. This cross piece is provided with a transverse groove 13 in which the spring lies. The bottom of the groove is curved, the center being preferably made highest, and the spring is curved to correspond therewith so that when the parts are assembled as in Figs. 5 and 6 the spring is securely held in position without additional fastening devices. The spring is made sufficiently strong so that there is no looseness of the parts in use and is found just as efiective after long continued use, thereby wholly avoiding repairs at this point and the substitution of new parts to prevent rattling.
Having thus described my invention, I claim 1. The combination with the upper circle of a fifth wheel and a yoke rigidlysecured thereto, of the lower circle lying between the arms of the yoke and a spring secured to said yoke between the arms of said yoke, and a spring In testimony whereof I affix my signaturein having lugs by which it is secured to the yoke presence of witnesses. by bolts passing through holes 5 and having DARIUS WILOOX.
arms which bear upon the lower circle upon \Vitnesses: 5 opposite sides of the yoke and hold said. lower J. E. LOVE,
circle in engagement with the upper circle, CHARLES GERHARD,
as and for the purpose set forth. THEO. NIGOLSON.
