Abstract: 1,264,402. Lubricating. TECHNISCHE HOCHSCHULE OTTO VON GUERICKE MAGDEBURG. 22 April, 1969, No. 20532/69. Heading F2A. [Also in Divisions F1 and H1] Apparatus for automatic control of oil apportionment in an I.C. engine comprises electrical control paths on a disc or other body which are insulated from one another and can be switched on or off and are shaped in accordance with the optimum courses to be taken by the oil apportionment, one or more scanning devices which scan the control paths in accordance with the rotation of an engine component, e.g., the crank-shaft, and are also adjustable in accordance with the rotational speed, a step switch which is electrically connected with the individual control paths and has a control element with one or more sliding contacts, the control element being adjustable in conjunction with the adjusting movement of a further engine component, e.g., the throttle valve, or directly adjustable, and a correction switch electrically connected with the sliding contacts and also constructed as a step switch. A stationary plate 24 (or a cylinder) provided with electrically conductive segments 25-38, each insulated from one another is swept by a rotating earthed contact 48 driven by the engine crank-shaft or cam-shaft. Each segment 25-38 is connected to a corresponding contact 25<SP>1</SP>-38<SP>1</SP> of a switch 80 having a shorting bar 81 linked to the throttle pedal 46 so that as the throttle is opened the segments 26-38 are progressively connected into circuit in parallel with the segment 25, whereby current is conducted by the contact 48 for a progressively larger proportion of each revolution. This current acts through an electronic switch 47 to open one or more electromagnetically operated lubricating oil injection valves 79. Consequently, the proportion of each revolution during which oil is injected increases as the throttle is opened. As the speed increases, centrifugal force moves the contact 48 radially outwardly against the constraint of a spring; since the boundaries between adjacent segments are non-radial, the effect of the outward movement is to alter the angular positions at which the injection begins and ceases. The shorting bar 81 has segments 83, 84, 85 which are insulated from the main part 82 of the shorting bar but can be progressively connected electrically to the main part so as to increase the effective length of the shorting bar and hence the duration of each injection. For this purpose, each segment 83, 84, 85 is connected to a corresponding contact of a correction switch 86 having a shorting bar 88 movable by means of a capsule 57 sensitive to atmospheric pressure and temperature and a capsule 76 sensitive to manifold pressure.

As shown a loop taker 41 is rotatable about the axis of a shaft 38 lying in the direction of work feed. A bobbin case retainer 47 is rotatably mounted in the loop taker and is prevented from rotating by a tongue 53 on a restraining member 49 fixed to the machine frame there being sufficient space between the tongue and the corresponding socket in the bobbin case retainer to allow the loop of thread to pass therethrough for retention on a retaining section 67 of a loop retaining member 65. The loop retaining member 65 is formed as a double armed lever normally urged by a tension spring 68 into the loop retaining position. To release the loop retaining section 67 a pivoted lever 75 is provided which rotates the lever 65 in the clockwise direction as shown in Fig. 5. The lever 75 is pivoted in a mounting member 77 which is adjustably secured to the restraining member 49 and the lever projects through the restraining member to contact the retaining member 65. The free end 75b of the lever 75 is normally upwardly urged by the spring 68 acting on the retaining member 65 and is moved downwardly at intervals by the end of the feed dog arm so that the loop thereon is released in synchronism with the needle and workpiece movements. When the machine is used for lock stitching it is necessary to provide a thread on the bobbin in the loop taken and to bluff the lever 75 and hence the loop retaining means 65 in the inoperative position. This bluffing operation is carried out by the replacement of the throat plate by a second throatplate having a downwardly directed bolt head in a position to lower the lever 75 out of the range of action of the feed dog and also into the inoperative position. A manually operable pivoted lever 94 is provided which when rotated has a projection 96 which lifts out the throat plate of the machine. The machine is of the free arm type and has a removable end cap on the free arm to prevent easy access to the loop taker.
