Title: Improvements relating to baling presses and methods of operating the same
IPC: G01G19/00
Filed: 1960-08-29
Abstract: 916,311. Baling machines. LINDEMANN, W. Aug. 29, 1960 [Nov. 16, 1959], No. 29726/60. Class 94(1). In a baling machine having a plunger 2 which repeatedly presses the material to be baled, the material delivered into the baling chamber 1 towards the final stages of each bale is automatically delivered in smaller amounts, so that, if some bales are formed with an extra delivery of materials, the difference in weight of such bales will be slight. On actuation of the hand switch 54, relay 37 is attracted for a period set by a switch 39 of a time mechanism 38 and fibrous material is supplied to the chamber 1 by means of a blower 17 driven by a motor 18. At the end of the set period the relay 37 drops and thereby, through a control swtich 44 and solenoid 46, causes an hydraulic valve 9 to drive the plunger 2 down, a switch 48 automatically causing the plunger to be raised. Switch 49 actuates the mechanism 38 for a further cycle. As the bale grows, pressure in hydraulic cylinder 5 increases until a relay 23, which may be pre-set, is operated to bring a switch 40 of the mechanism 38 into play in place of the switch 39. This causes the motor 18 to operate for shorter periods, blower 17 thereby supplying smaller amounts of material. Finally, pressure in the cylinder 5 is sufficient to actuate a relay 24 and return the valve 9 to its orignal position, thereby arresting the plunger 2. The bale may then be corded and removed.

Abstract: 1,013,699. Wrapping rolls of material. H. COLSMAN, (trading as COLSMON & KIRSHNER). Aug. 4, 1964 [July 19, 1963; Sept. 25, 1963], No. 30532/64. Heading B8C. [Also in Division F2] Wrapping material overhanging the end of a roll is twisted by spiral members 1a (Figs. 1 and 2), fixed to a funnel 1, and forced against the end of the roll, by relative motion of the roll and funnel. In the form shown (Fig. 1), a projection 6a on a driving wheel 6 engages a longitudinal groove 2a in a threaded spindle 2 rigidly attached to the funnel so that the spindle is screwed through a nut 3 and advanced in the direction P. Pawls 17, which during this motion have engaged and been held in recesses 13a are then disengaged so that compressed springs 12 can expand to advance a pin 9 rapidly in the direction P and push the wrapping into the interior of the roll. In a secondembodiment (Fig. 5), the spindle drives the funnel through a split nut 30 (see Division F2), which disconnects the drive, when the torque transmitted is raised to a limiting value by friction between the funnel and the wrapper. The spindle 2 then continues to advance in the direction P without rotation of the funnel 1 so that the end element 29a forces the wrapping material into the interior of the roll. The member 1 is then withdrawn from the end of the roll and does not start rotating until the lost motion at 33a is taken up. Preferably, the roll is lowered on rollers R (Fig. 4) between two such apparatus B and the longitudinal closure B completed at the same time as the end closures.
