  • This power unit may be of the same general construction as the unit disclosed in the patentto Peets et al., No. 2,004,055, granted on June 4, I935. It involves an axially slidable sleeve carrying a shaft on which is mounted one member of a friction clutch and on which is also mounteda pulley 'll connected by a belt 32 with the pulley 31 of the sewing machine. As best in Fig. 7, the pulley 3! is splined to the end of the driven shaft 43 of the clutch.
  • This shaft is provided with a screw threaded portion 4%, extending beyond the outer face of the pulley l'l which carries an internally threaded portion c5 of asle'eve-like extension 46 of a handwheel 41.
  • This h'andwheel is so positioned as to be readily accessible to the operator and eliminates the inconvenience of turning a combined handwheel and pulley, normally provided in the position of the pulley 31, for turning the main drive shaft of the sewing machine by hand.
  • elongated openings 48 are providedthrehgn the plate member (see Figs. 4, 8' and- 9'). These openings are arranged to receive bolts 49 having enlarged heads 50 cooperati'ng with the under surface of the plate member adjacent the openings.
  • Each bolt has a nut 51, in threaded engagement with its upper end, arranged to be screwed tightly against a sleeve 52 which surrounds the bolt and at its lower end engages the upper surface of the plate member [5.
  • a vibration abs'o'rbing sleeve 53 Surrounding the sleeve 52 is a vibration abs'o'rbing sleeve 53 formed in two parts, upper and lower, of rubber or felt or other yielding material. Each of the parts of sleeve 53 has an outwere-1y ex tehcrhg flange arranged to cooperate with one of the faces of a foot 54 formed on the frame of the drivingu'nit. Washers 55 are preferably provided at the outer ends of the sleeve 53.
  • the arrangement is such that when the nut 5
  • the vibration isolating elements 53 and the sleeve 52 may be omitted, since it has been found that the elements lle serve quite effectively to isolate any vibration imparted to the supporting plate It, whether derived from the sewing machine or the power unit. It is, however, preferred to eliminate the transmission of vibrations from the driving unit to the plate by the use of the sleeves.
  • a pair of treadles 56 and 5! is provided for controlling various functions of the unit.
  • 'Ireadle 55 for example, is adapted to lift I scribed, with a lubricant pump.
  • Treadle 51 is arranged to control the clutch of the power unit to determine at will when 1 the sewing machine is to be driven. Suitable connections from this treadle are also provided for operating a pump arranged to transfer lubricant from certain points to others within the sewing machine frame, as'will be explained hereinafter.
  • the treadle 51 has downwardly extending supporting ears clamped to a rock shaft 58 suitably journaled in the base I0.
  • the left end of this rock shaft is bent at right angles, as indicated at 59, and extends to a point beneath the lower end of the column I2.
  • a rod 60 which extends upwardly through the column.

  • rocking of the sleeve 66 by a downward pull on the arm of yoke 64 will cause the sleeve to be shifted axially to engage the clutch and cause the pulley M to be driven.
  • the connection between the yoke 64 and the rod a preferably includes a ring 61 secured to the yoke and extending inwardly therefrom.
  • Rod 60a passes upwardly through this ring and carries a collar 68 cooperating with the under face of the ring.
  • a spring 69 is compressed between the upper face of the ring and a washer I0 carried by the rod 60a and held thereon by an enlargement of the upper end thereof. It will be seen that in this way the arm 64 is normally held against the collar 68 but as the rod 60a is moved downwardly the yoke 64 isyieldingly urged downwardly but is not positively forced in this direction. After the clutch has been engaged the further movement of the treadle and corresponding downward movement of the rods 60, 60a serves to compress the spring 69 to increase the pressure between the clutch faces.

  • the ball element may be positioned in either of a plurality of openings 15d in a bent-over branch of the arm15. This permits the ball element to be mounted in the position best suited for the particular adjustment of the power unit on the member I6.
  • a downwardly extending arm I9 of the lever is connected by means of a rod or link with a piston rod 8
  • the latter may suitably be of the type disclosed in the patent to Smith, No. 2,430,370, granted November 4, 1947, and may be arranged to transfer lubricant from different points within the sewing machine frame to suitable reservoirs for distribution to the various parts requiring lubrication, all as fully set forth in said Smith patent.
  • Rod 63 connected with the treadle 56, this, as best shown in Figs. 1 and 2. is connected at its upper end with an arm 63.
  • Rod 63 passes through an opening in the arm 83 and carries a collar 84 above said arm having a spherical lower end arranged to engage the upper'surface of the arm.
  • a sleeve 85 surrounding the rod 63 engages the under surface of the arm 83 and is held in such position by a collar 86 secured to the rod.
  • a slight clearance is pro-' vided for the arm 83 between the collar 84 and sleeve 85 to permit the necessary relative movement between these parts.
  • a spring 87 connected withthe outer end of the arm 83 and with the collar 86 serves to take up the play between the parts and holds the arm against the upper end of the sleeve 85.
  • Arm 83 is integral with, or otherwise connected with, a sleeve 88 secured by a set screw or the like to a rock shaft 89 journaled in bearing lugs 90 and 9
  • Another arm 92 (Figs. 2 and 3) extending rearwardly from the sleeve 60 has a spring 93 connected with its outer end, said spring having its opposite end attached to a small bracket 94 secured to the support member I4. This arrangement is such that the shaft 89 is urged in a counterclockwise direction (Fig. 2) and tends to urge the rod 63 upwardly.
  • lever 91 in the foregoing linkage performs the same function as the bell crank lever 53 in the construction ofthe Smith patent above mentioned and the operation of the linkage is such as to bring about lifting of the presser bar I00, upon the depression of the treadle 56, in opposition to the spring IOI (Figs. 1 and3).
