SPRING-WHEEL.

Specification of Letters Patent.

4 Patented Nov. 20, 1906.

Application filed March 17, 1906. Serial-No. 306,680.

To all whom it may concern:

Be it known that we, FELIX J. BIEHN and Or'ro BIEHN, citizens of the United States, residing at Madison Lake, Blue Earth, State of Minnesota, have invented certain new and useful Improvements in Sprin -VVheels; and We do hereby declare the fo lowing to be a full, clear, and exact cle-- scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wheels,andmore particularly to spring-wheels, and has for its object to provide a wheel of this kind which will be simple, which will include few parts, and which may be produced at low cost.

The primary ob ect of the invention is 'to provide a wheel of a resilient nature which will absorb the shocks incident to passing over rough or'uneven surfaces.

Other objects and 'advantageswill be ap-' parent from the following description.

In the drawings forming a portlon of this specification, and in which like'numerals of reference indicate similar parts in the several ure 1 is an elevational view of the eel. Fig. 2 is a vertical sectional view. Fig. 3 is a section taken at ri ht angles to Fig. 2 on line 3 of'Fig. 1. I ig. 4 is an enlarged detail section of one of the spokes. Fig. 5 is a perspective view showing the memone of thespokes disconnectedthe drawings, there is rising a hub including a air of spaced'annu ar plates 5, the openings of which register for the reception of a boxin 6, and the lates thus form what are, in e feet, space circular flanges lym in parallel relation. The flanges are eac 1Erovided erforations 7, t e perfo ining in anges a1 ivotins 8, and pivotally present w Referring now to rations of the two the reception of on of a spoke, there being t us a plurality-of these spokes having erforations 9 therein at their inner ends w 'ch the pivot-pins 8 are engaged. Eachf spoke consists of two telescoping sections-an inner section 10, in which the opening 9 reformed, and an outer section 11, havin at its outer end a perforasection 10has alongitudiual chamber 12 therewithin which opens through the outer end of in the county of ,felly 19, there lar plates, a oxing engaged gaged in each pair pairs for of t ese ins is the'inner the perforation 9. The

and the inner ends of its inner portion the chamber 12 is reduced, as shown at 13, both portions of the chamber being transversely circular. The outer section 11 of each spoke this section, and at is engaged within the'chamber 12 .of themner section and has an inner reduced end 14, which extends into the reduced portion 13 of the chamber 1 2, The formation of the reduced end 14 of the section 11 results in.a shoulder 15, and engaged wi h the portion 14 thereis a helical s ring 16, resting at one end against the shou der.15 and at its other end against a shoulder 17, formed, as will be understood, b the reduction of the inner portion of the c amber 12.

The sections 11 of the several spokes, as will be readily understood, are held by the springs 16 yieldably against inward movement, and t ,e outer end of each of these sections 11 lies between a pair of inwardlys 18, which are carried by a eing one pair of these wings 18 for each spoke, and the erforations 9 of the"sections 11 register wit alining pairs of perforations 20, formed in the the rece tion of pivot-pins 21. be seen t at the sfpokes, the are susceptible o sl' ht pivotal movement at their. connections. ashers 22 are. engaged with the pivot-pins 8 and 21 at opposite sides of the s okes to prevent lateral movement of the spo es upon the pivot-pins, and it will be seen that new washers may be for worn onesg extending It will thus 1 4 What is claimed is hub, and the felly Wings 18 for substituted A. wheel com risinga of spaced amiu plates, said plates having pairs. perforations therethrou h, a pivot-pin enof pe orations, spokes including inner and outer sections and having perforations at their inner ends in which the ivot-pinsare engaged, said inner sections aving chambers therewithin opening through their, outer ends and havin sections being engaged within the chambers within] the ot alining reduced innerl portions and resultant shou ders, said outer} j roo of the inner sections and having reduced por- I into the reduced portions of rings engaged with the reduced portions .0 the outer sections,
