Definitions

  • This invention relates to connecting rods such as are used, for example, between a sewing machine foot-treadle and a power transmitter which drives the sewing machines.
  • the invention has as an object to provide an improved connecting rod which is readily adjustable as to length; which is rattle proof; which does not transmit objectional vibrations from the power transmitter to the foot-treadle; and which affords a limited amount of resiliency between the treadle and the actuating arm of the power transmitter.
  • the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.
  • Fig. 1 is a front side elevation of a portion of a sewing machine table having secured thereto a sewing machine and a power transmitter and showing also a portion of a foot-treadle and my improved adjustable connecting rod between the treadle and the power transmitter.
  • Fig. 2 is a detail view of a power transmitter actuating lever to which my improved connecting rod is adapted to be attached.
  • Fig. 3 is an enlarged sectional view taken substantially on the line 3-3 of Fig. 1, showing the connection between the foot-treadle and my improved connecting rod.
  • Fig. 4 is an enlarged perspective view, partly broken away, of the improved connecting rod.
  • Fig. 5 is an enlarged vertical sectional view of a portion of the improved connecting rod.
  • Fig. 6 is a face view, looking in the direction indicated by the arrow A in Fig. 5, of portions of the adjustable connecting rod.
  • Fig. 7 is an enlarged longitudinal sectional view taken substantially on the line 1-1 of Fig. 6.
  • Fig. 8 is an enlarged transverse sectional view taken substantially on the line 8-8 of Fig. 6.
  • Fig. 9 is a detail view, partly in section, showing the means for connecting together two parts of the improved connecting rod.
  • Fig. 10 is a detail perspective view of a modified form of yielding connection between the improved connecting rod and the actuating lever of the power transmitter.
  • the invention is disclosed as comprising a composite connecting element 0 between a sewing machine foot treadle T and a power transmitter P.
  • the power transmitter is shown as secured to the under side of a table top I which is supported upon a suitable metal framework 2 and carries a sewing machine S which is driven from the power transmitter by a belt 3.
  • the treadle T is mounted for oscillation on a rod 4 supported by the framework 2.
  • the framework, treadle, table-top, power transmitter and sewing machine are of conventional form and constitute no part of the present invention.
  • the power transmitter may be of the type shown in United States patent to Peets et al., No. 2,004,055, June 4, 1935, and has a clutch-operating arm 38 (Fig. 2) the oscillatory motions of which, under the action of the foottreadle, efiect, alternately, driving and stopping of the sewing machine.
  • the foot-treadle T is preferably of the type having a sheet metal foot-plate 5, formed with a downturned marginal flange 6, to which is adjustably secured, by bolts I, a channel-like extension bar 8.
  • This extension bar has a laterally oiis'et portion 9 to which is secured, by nuts I0 and II, the shank I2 of a ball-stud I3 to which the lower end of the connecting rod C is attached, as hereinafter will be described.
  • the composite connecting rod C comprises a bar I4 to the upper end of which is secured a fiat sheet metal member I5 shaped to provide a loop I5 in which is supported, by opposed coilsprings I6 and I1, one end of a transversely projecting power transmitting pin I8.
  • This pin is fitted into bores formed in lugs I9 and 20 projecting laterally from the clutch operating arm 38 of the power transmitter.
  • secured upon the pin [8, between the lugs I9 and 20, by a set screw 22, prevents withdrawal of the pin from said bores but permits a slight axial movement of the pin relative to the arm 38.
  • the bar I4 is yieldingly connected to the pin E8 in such a manner that vibrations caused by the sewing machine or by the power transmitter are not transmitted to the connecting rod and to the foot-treadle.
  • the springs l6 and I1 3 also provide the desired amount of resiliency between the treadle and the actuating arm of the power transmitter, the opposed action of the springs is such as to reduce lost motion to a minimum in bringing the sewing machine into operation.
  • the bar I4 and the member I5 are joined together, as shown most clearly in Figs. 4 and 9, by fitting the. upper end portion of the bar between laterally spaced fianges or wings 21 provided on the member I5; fitting a stud 28, punched from the bar I4, into an aperture 29 formed in the member I5, and finally spot-welding the parts together as indicated. at w.
  • the channel bar 32 constitutes.the lower element of the composite rod C.
  • a sheet metal retaining element, or sleeve 33 which is sub stantiaily rectangular in crossesection and is provided, in one .wall,.with a slot 34.
  • the relative lengths ofv the bar. 14, channel member 32 andsleeve 33 are such thatthe sleeve may he slid upwardly on the. bar to completely uncover the channel member 34, even when that member isin itsuppermost position on the bar. With the parts thus separated.
  • the member 34 may be repositioned on the bar with the studs 31] fitting into any selected apertures 3i, after which the sleeve is sliddownwardly to; embrace the member 34 and hold theparts in adjusted position.
  • theover-alllength' of the connecting rod C may be readily varied at will, with the composite parts securely locked against relative movement.
  • The; face and side. walls of the sleeve 33 are notched, as indicated at: 35, to provide inwardly pressed resilient flat fingers 36 which bear upon the back wall of the channelbar 32, as shown most clearly in Fig. '7, thereby to compensate for variations in the thickness of the. materials from which the parts, are made. as well as frictionally to maintain the sleet/e33 against accidental endwise movement and hold it against rattling.
  • the fingers 36 are preferably curveclin crosssection (see Fig. '7) toavoid interference between the parts andthereby facilitate sliding of the fingers over the upper, endof the channel member 32 when the partsareassernbled.
  • the lower end, of the channel bar 32 is formed with an enlarged fiat, hollow head 3] which cooperates with a similarly shaped cap 39, secured thereto by screws M1 threaded into the bar 32, tov provide a socket-l I adapted to receive the ballstud I 3, and av substantially cylindrical portion 42 adapted to house a coil spring 43.
  • One end of the spring bears. against the upper inner wall of thehollsing 42, while the other end thereof bears against a frictionshoe. which, in turn, bears upon the surface of the ball I3.
  • Lock nuts 45 threaded upon the screws 40, prevent accidental loosening of the; screws.
  • Fig. 10 there is illustrated a modified form of yielding connection between the bar I4 and the transmitter actuating arm.
  • the bar i l has a reduced upper end portion I l and affords shoulders M adapted to support a plate-like washer 46.
  • a similar plate-like Washer is fitted upon the reduced portion I l and is held against outward movement thereon by a coilar iii, secured to the bar by a set screw 49.
  • a suitably apertured block 52 carrying a projecting pin 53, adapted to be held in the bores in the lugs l9 and 20 on the clutch operating arm of the, power transmitter, as hereinbefore described with respect to the pin I8.
  • the springs 55 yieldingly support the bar I4 from the pin 53 and prevent vibrations being transmitted tothe. bar as do the coil-springs I6 and IT.
  • An adjustable connecting rod comprising a channel member; a bar member having one end portion fitted into said channel member, one of said members having therein a plurality of apertures arranged lengthwise thereof and the other of said members having. a stud projecting therefrom and adapted to be fitted into any one of said apertures, thereby. to lock said members against relative endwise movement; a slidable sleeve embracing said members to prevent lateral separation thereof; and friction means acting on said sleeve to. maintain it against accidental endwise movement.
