WILLIAM H. NQELTING AND EMIL A. SMITHFIELD, F EVANSVILLE, INDIANA, AS- SIGNORS TO FAULTLESS CASTER COMPANY, OF EVANSVILLE, INDIANA, A COR- RIGID (EASTER;
7 Application filed July 14, 1924. Serial No. 725,999.
Z70 all iokom it may concern :Be it known that we, W'ILLIAM H. N OEL- FTING and EMIL A. SMITHFIELD, citizens of the United States, and residents of Evans- ,ville, county of Vanderburg, and State of Indiana; have invented a certain new and useful 'R-igid Caster; and we do hereby de- "clare that the following is a full, clear, and
exact description thereof, referencebeing had to the'accompanying drawings, in which like numerals refer to like parts.
This invention relates to a rigid truck type caster.
.The chief object of the invention is to produce a caster which can be made from sheet metal of relatively thin gauge and so fashioned that it has greater strength than cast iron casters of considerably greater weight. The several features of the invention whereby relatively thin gauge metals may be fashioned into a caster adapted to be rigidly secured to trucks for heavy duty consists in vertically corrugating the side planes of a caster arcuately depressing the ends of the triangular shaped side flange, corrugating the base or top plate and forming the securingholds in an improved manner.
The resultant construction consists in a single'shect for relatively thin gauge metal fashioned as aforesaid to produce a caster having great strength and have economical production costs.
The full nature of the invention will be understood from the accompanying drawings and the following description and claims:
Fig. 1 is a side elevational view of what is commonly called the truck type caster. Fig. 2 is a top plan View thereof. Fig. 3 is a bottom plan View of the same. Fig. 4 is an end view. Fig. 5 is a central sectional view through an opening or securing hole and the associated parts.
In the drawings there is illustrated a top plate having a substantially circular portion 1.0 and two diametrically positioned fan tail or wedge shaped extensions 11. In each of the extensions 11 there is provided a pair of openings 12 and opposite openings are also diametrically positioned as shown by the dotted lines in Fig. 2.
In order to secure the greatest strength the top plate or base includes a circular corrugation 13 con entri with the subst ntially circular portion 10. Concentric with the corrugation 13 and substantially at a junctionbetween the fan tail extensions and the circular portions of the base, there is formed an arcuate or curved corrugation 14.. Likewise medianly positioned between the openings 12 of each extension 11 is a longitudinally extending corrugation 15 and herein corrugations 15 and 14C join to form a T shaped corrugation, the baseor'head of which is curved and concentric with the circular reinforcing corrugation. The circular reinforing corrugation insures against collapse of the circular portions of the base in any diametral plane. The curved corrugation 14 insures against longitudinal bending of the plate along the longitudinal axis. The longitudinal corrugation insures against bending along the transverse axis at the junction between the extensions 11 and the circular portions of the base 10.
Extending downwardly from each of the elongated sides and conforming to the outline thereof is a triangular shaped side flange 16 and there is thus secured a side flange having the corrugation at each end and approximately one third in therefrom which insures against bending in a horizontal plane. The intermediate and enlarged or arched portion is not only drawn downwardly but is also drawn inwardly as shown clearly in Figs. 1, 3, and 4 and thus there is produced an arching effect giving relatively greater clearance at the tread portion of the wheel 17 pivotally supported by the pin or bolt 18 in the openings 19 formed substantially at the apex of the inverted triangular frame. As shown clearly in Fig. 1 the triangular frame work adjacent this opening is formed flat as indicated by the numeral 20 to form a pair of parallel bearing plate portions.
Reference will now be had to Figs. 2, 3, and 5. In said figures the openings 12 are illustrated as defined by a corrugated por tion 21 immediately concentric to said opening and herein said corrugation includes the inturned portion 22 that defines said opening.
The inturned tubular portion 22 is adapted to be drawn toward the supporting member 23 by a bolt 24 to the nut 25. If the material 23 is of wood or relatively soft material the tubular portion will seat itself ciated with pin 18, they are Securedinsub in said material. Furthermore the foregoing constmction also acts/as alock nut'for after the nut has been turned up "onthe screw threaded bolt 24, the same-is held -,-again st rotation.
a The sideflanges .16 are fashioned so that normally they are divergent. When assostantially parallel relation in opposition to a tendency to separate thereby-positively in-' suring clearance for the wheel 17 The inventionclaimed is Y 1.
