Application filed January 9, 1922. Serial No. 528,054.
To all 10710721. it may concern.
Be it known that I, Jossrrr W. HRUsKA, a citizen of the United States, residing at Mankato, in the county of Blue Earth and 5 State of Minnesota, have invented certain new and useful Improvements in Runners; and I do 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.
This application is divisional of my pending U. S. application, Serial No. 51,209, filed December 16, 1920, on improvements in road drags, and while the runner which constitutes the subject matter of the present application, may be used upon machines of this character, it is to be understood that the invention is not restricted to any particular field of use.
The object of the invention is to provide an extremely simple runner which may be constructed entirely of angle metal, an I- beam being preferably employed. Novel provision is made whereby one of the flanges of the metal beam is longer than the other and forms the shoe for the runner and is bent upwardly at its front end to impart the conventional shape to the front end of the runner.
With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the descriptive matter being supplemented by the accom panying drawing.
Figure 1 is a side elevation of an L-beain showing the first step in constructing a runner in accordance with the present invention.
Figure 2 is a side elevation of a complete runner.
Figure 3 is a vertical transverse section as indicated by line 3-8 of Fig. 2. I
In the drawings above briefly described, the numeral 1 designates an angle metal beam which is preferably but not necessarily in the form of an I-beam whose flanges 2 extend in opposite directions from its web At one end, the beam 1 is formed with a V-shaped notch 4 whose lower side is flush with the upper surface of the lower flange 2, while the upper edge of said notch declines from the forward extremity of the upper flange to the lower flange 2. After notching the beam in this manner, the front end of the lower flange 2, which is longer than the upper one, is bent upwardly into contact with the curved edge 5 and is welded or otherwise secured thereto. By this construction, it will be seen that a metal runnor may be conveniently and cheaply manufactured and it is to be noted that the lower flange of the beam with its upwardly curved front end, forms a shoe for engagement with the surface upon which the runner is intended to slide.
Attention may again be directed to the fact that while the parent application shows the runner applied to a road drag, it is usable also for numerous other purposes and while an I-beam is preferably used, it will be understood that any other suitable angle metal beam could be employed.
A runner formed from an I-b-eam, the base flange of which has its forward end e:-:- tended beyond the corresponding end of the top flange, the web of the beam having a substantially V-shaped portion cut out from its forward end forming a notch, the lower edge of which is flush with the upper face of the base flange, the other edge thereof being curved downwardly and inwardly from the extremity of the top flange to a point spaced inward from the forward eX- tremity of the base flange, the latter being bent upwardly against and secured to said curved edge to impart the usual shape to the front of the runner.
In testimony whereof I have hereunto set in hand.
