.JAMES FRED' GOIIIIDGE IIIINOIS- A oonNEvoTiNG-nop.
IEpatented March 13, 1906.
To all whom t may concern:
Be it known that I, JAMES FRED Coox, a citizen of the United States of America, residing at Cambridge, in the county of Henry and State of Illinois, have invented new and useful Improvements in Connecting-Rods, of which the following is a speciiication. i
This invention relates to improvements in connecting-rods for internal-combustion engines, its object being to provide .a rod of maximum strength to withstand the strain to which rods of this character are subjected and in which provision is made for the eective adjustment of the hinged caps of the coupling-bearings to compensate forI wear.
lThe preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 isla vertical longitudinal section of the connecting-rod, Fig. 2 -is a top plan view thereof, and Fig. 3 is a central vertical transverse section.
Referring now more particularly tothe drawings, the numeral 1 represents the body portion of the rod, which comprises a channeled bar of substantially H form in cross- `section and which is formed at its opposite ends with the stationary bearing members 2 and 3, each of which is provided at one side with an ear 4 and at the oppositey side witha projecting lug or jaw 5. f
Coperating with thel respective stationary bearing members 2 and 3'are adjustable bearing members or caps 6 and 7, which form therewith couplings for engagement with the piston and crank-shaft. Each'of these caps is formed at one side with an earv 8 and at the opposite side with a projecting lug or jaw 9,
' through the lugs or jaws 5 and 9 of the coupling members 3 and 7 the said end ofthe bolt being formed with a head 13, bearing against lthe outer face of the lug 9 and with an adj acent polygonal portion 14, which fits within a corresponding opening in said lug and holds the bolt from turning.- 4The opposite end of the bolt passes through openings in the lugs 5 and -9 of the coupling members 2 and 6 and is ingagain'st the lug 9vand serving to hold the bolt in adjusted position. The bolt is thus adapted to be adjusted in a diagonal direction relatively to the bar 1 to move the hinged caps .6 and 7 toward and from the co erating stationary coupling members 2 and 3 to adjust the'same for engagement with piston-connection pins and shafts varying in size and to compensate for wear. As the bolt extends diagonally through the web or central connecting portion of the bar 1 and lies between the side plates or flanges of the latter, it will be apparent that these parts will be mutually stayed and braced and that the' peculiar arrangement of the bolt prevents the strain falling upon one coupling member from being transferred directly to the other coupling'member, such strain being taken up by the body of the rod, which is` best adapted to sustain it. The
bolt itself is alsoV stayed centrally by the web and held from flexion, a great advantage in devices of this kind. A connecting-rod is thus provided which is of maximum strength to withstand the strain to which the connecting-rods of internal-combustion engines are threaded for the reception. of a nut 15, bearsubjected and which embodies means for securing an effective adjustment of the hinged I caps of the coupling-bearings.
Having thus described'the invention,v what A is claimed as new is* AA connecting-rod comprising a body portion formed of parallel longitudinal plates arranged edgewise in a vertical plane and free from connection between their edges so as to prevent the transmission of strain above the centerline from one plate to the other, whereby saidl body portion is relieved from excessive stiness, said body portion being provided with stationary bearing members integral with the ends of the plates and forming the sole connections therebetween, caps cooperating with the bearing members to form couplings, said caps being hinged tothe stationary members on opposite sides of said body portion, and a stay-bolt extending diagonally between the body-plates and terminally connected with the hinged members of the coupling-bearings to adjust the caps toward and from the coacting stationary bearing members, one end of the bolt having a connection with .one of the stationary bearing members to hold said bolt from rotation, the body portion also being provided withV a bracing-web extending horizontally and longitudinally between the body-plates and con- IOO IIO
neeted at its ends with the stationary bearing inforeed at the center of the rod to stay the members and its side edges with said bodysame against both vertaal and transverse plates at a point substantially midway of the strain,
upper and lower edges thereof, said web hav- In testimony whereof I afiix my signature 5 ing an opening for the passage of the bolt and in presence of tWo Witnesses.
