SHAFT-DRIVING MECHANISM.
Specification of LettersPatent.
Patented May 22, 1917.
Application filed November 3, 1910. Serial No. 590,580.
the accompanying drawing and to the letters and figures of reference marked thereon, My invention relates to improvements in driving mechanism, .and particularly to a mechanism connecting two rotary shafts to drive one from the other.
I have particularly designed this movement for use in sewing machines for driving the lower shaft from the upper or belt wheel shaft, or vice versa, and have denominated it a three-crank drive for upper and lower shaft machines.
Broadly, a three-crank drive mechanism is not new, but my invention consists in the details of construction and arrangements of parts, as hereinafter described and referred to in the appended claim.
The invention is illustrated in the accompanying drawings, in which,
Figure 1 is a side elevation partly in section, of a sewingmachine having my improved driving mechanism;
Fig. 2 is a detail side view of one of the 'triple crank pieces; V
Fig. 3-is an end view ofthe same; Fig. 4: is a face view of one of the pitmen and the connecting rod; .Fig.. 5 is an edge view of the same; Fig. 6 is a detail showing in side view one of the two-part hardened collars which engages a crank pin;
Fig. 7 is an edge view of the same. In these drawings, A represents the upper shaft, and B the lower shaft, suitably supported in bearings, and each in two parts and joined to the crank piece O.
Each crank piece has the sleeves D to receive the adjacent ends of the shafts, and
has the four crank disks a, and the three ,crank pins b arranged 120 apart. On each of the crank pins b are stop pins 0, arranged to hold the case-hardened bearings at in place. These case-hardened bearings are made in two parts and secured together'by oppositely arranged screws 6, which clamp the bearings firmly on the crank pins. By
.making. the hearings in two parts, case'- hardening them and securing them on the crank pins, it is possible to make the crank piece of soft steel, and'thus avoid the danger of warping the same if it were hardened.
E represents the straps surrounding the bearings at one end and having the oil opening 6.
On the opposite end the straps are flattened and formed with side ribs or flanges f to receive the ends of the pitmen F, which have an elongated slot g, through which.
passes a screw Z1. into the flattened portion of the strap E. Thisprovides for a slight vertical adjustment of the pitmen F. These pitmen are of steel, tapering in thickness from the center toward each end, and also from the center toward each edge, thereby combining lightness with great strength.
Having thus described my invention, what I claim as new and desire-to secure by Letters Patent, is:
.A power transmitting mechanism comprising a shaft having a plurailty of cranks intermediate its ends, said cranks being arranged adjacent to each other-and angularly disposed to each other, said shaft and cranks being formed of soft tempered metal, a twopart case-hardened bearing" secured to each LANSING oNDERDoNK.
