Title: A mowing unit
IPC: A01D34/06
Filed: 1968-05-13
Abstract: 1,221,117. Mowing unit. DEERE & CO. 13 May, 1968 [13 May, 1967], No. 22574/68. Heading A1F. A side mowing unit carried and driven by a tractor and arranged to swing back against the action of a spring, is characterized in that the swing axis is positioned between a driving pulley on the tractor and a driven pulley on the unit so that, upon yielding to an obstacle, the unit is immediately disconnected from a latch device and from the drive. Referring to Fig. 1, the cutter (not shown) extends to the left and is pivotable between the lugs 6, 8 of a yoke 2. A pin 20, on which the yoke is pivoted, terminates in a vertical tube 36 which is supported between the arms 40, 42 of a frame 1 fixed to the tractor (not shown). A screw 44 secures the tube 36 to a swivel pin 38 received in the arms 40, 42 thereby providing a swivel axis that is disposed between a driven pulley 10 and a driving pulley (not shown) on the tractor. Extending from tube 36 is a rocking lever 48 pivotally carrying a link 50 of the latch device 46 held between the jaws 60, 62 of the frame 1. The link 50 is slotted to receive a bolt 74, so that, on swinging back, the unit does not pull the club-portion 56 of the link completely from the jaws. In a modification the swivel pin (38), Fig. 4 not shown), is inclined to the vertical so that when the unit swings back an outer shoe of the unit is relieved of load. In this arrangement the rocking lever (48) carries a universal joint to enable a hooked portion of the member 56 to engage the jaws on returning to the working position thereby eliminating the action of the spring.

Title: Convey belt system for the distribution of tickets, letters and the like articles
IPC: B07C3/06
Filed: 1951-09-28
Abstract: 746,746. Belt conveyers for distributing letters &c. STANDARD TELEPHONES & CABLES, Ltd. (Mix & Genest Akt.-Ges.). Sept. 28, 1951, No. 22677/51. Class 78 (1). A deflecting tongue movable to and from a projected position in which it intercepts and deflects articles on a conveyer belt from the belt is automatically returned to non-projected position by the actuation of stationary electric contacts by the article being deflected, which produces two circuit changes at the beginning and end, respectively, of the actuation, these changes together resulting in the return of the tongue. As shown, tickets 7 are conveyed on edge along a vertically slotted guide 1 by a belt 2. The tickets travel past a number of deflecting tongues 3 which can be selectively operated to pivot into the path of the tickets to divert them to corresponding delivery stations. Each tongue is actuated by an electromagnet 10 whose armature 12 moves through a lever 9 a metal roller 6 having a rubber ring 5, which is in engagement with tongue 3 through leaf springs 4, 8 on the latter. At the same time an enlargement 11 of the roller presses against the edge of the belt causing the latter to drive the roller such that as a ticket is diverted from the belt by the tongue it is gripped between the rubber ring 5 and leaf spring 4 so that the rotation of the roller pulls the ticket along the tongue from the belt. Leaf spring 8 and the metal body of the roller form an electric contact which is broken by passage of the ticket therebetween. This is arranged to break the circuit of a primary relay in the control circuit of electromagnet 10 but maintain a circuit through a first winding of a second relay which holds in the electromagnet until the contact is re-established, whereupon a current flows through a second winding of the second relay to neutralize the effect of the first winding and thereby break the circuit of the electromagnet 10. The tongues 3 may be mounted in guide 1 by a leaf spring instead of pivotally as shown.

Class 125(iii) A stopper 2 for milk bottles &c. 1, 11, consists of a cup-shaped member of indiarubber or like material, adapted to enter the neck of the container with an upper bead or rim 3 to bear upon the edge of the neck, and a bead 4 between the upper bead or rim and a thickened bottom 5 which is substantially thicker than the portions 6, 7 uniting it to the upper bead or rim and the thickened bottom, the external diameter of the cup, downwards from the upper bead or rim, first diminishing and then increasing to form the lower bead 4. The thickened bottom 5 has a downwardly directed convexity. The stopper is inserted by pressing downwardly on the portion 5 to reduce the diameter of the bead 4 which then makes a fluid-tight joint with the container when the pressure is released, and is removed by first reducing the diameter of bead 4 in similar manner. The bead 4 has an extra thickness 4<SP>1</SP> which is rounded or formed with a tip, and when the stopper is inserted part 6 is drawn out and part 7 compressed so that they act on the bead to give fluid-tightness, and if the container is upset the contents acting on the bottom 5 hold the stopper more firmly in position. The rim 10 may overlap the edge of the container, as in Fig. 6, so that it may be removed without the operator contaminating the container edge. The upper part of the stopper may be conoidal as at 13 in Fig. 8, or be turned back as at 14. Two or more beads 4 may be formed as shown in Fig. 9.
