As the bed-settee is folded the outer bed section 25 is pulled into substantial parallelism with the inner bed section 23 by support arms 29 pivoting anticlockwise, thus causing bell crank levers 34 to pivot and displace leg actuating links 48 and links 60, and bell crank levers 58 to pivot and displace links 67. The links 60 make a lost motion connection between the support arms 29 and the bell crank levers 58. The link 67 carries a stud 69 which abuts against a stop 70 on the section 23 when the outer bed section 25 is parallel thereto. The head bed section 22 also carries a stud 42 which prevents folding, when pressure is exerted at the head end of the bed, by link 32 abutting thereagainst. The legs 47, 53 are folded and extended automatically with the sections by movement of links 48 and 55. The bedsettee may have fitted cushions, Fig. 5 (not shown) or loose cushions C, Fig. 9 (not shown), the back structure 112 being narrower in the later than the former so that the support arms 26 protrude beyond the back in the settee position. To allow for this the support arms are bent and slots are provided betwen the back structure and arm panels 13a to receive the support arms 26.

Filed: 1975-06-06
Abstract: 1482244 Ball throwing machine G BERLINER 6 June 1975 [11 Sept 1974] 24483/75 Heading A6D  A ball-throwing machine for use in practicing table tennis comprises a pair of flexible discs 74, 76 (Figures 10 and 11) adjustably mounted on a shaft 72 which is driven by a motor 70, an arrangement for feeding balls 12 between the discs 74, 76 whereby each ball is gripped therebetween land thrown therefrom so that as it leaves the discs it is in contact with one of two guides comprising members 90, 92 and 94, 96 respectively which imparts spin to the ball. The position of the guides relative to the discs may be adjusted either so that only one of the members 90, 92, 94, 96 contacts the ball thus giving it side spin, or so that both members of the guide, with which the ball is in contact, contact the ball. The direction of rotation of the shaft 72 will determine which of the two guides a ball will contact and hence whether the ball is given top spin or bottom spin as it leaves the discs. Balls may be fed to the discs from a hopper device 18 by an arrangement comprising a rotating notched disk 84 and a deflector 85. Balls which are returned towards the machine by a player are caught by a net 16, (Fig. 1) which directs the balls to a trough 156 which conveys the balls to a tube 26 through which they are returned to the hopper 18 under the action of a partial vacuum created by a fan in the hopper. The direction in which balls are projected may be adjusted by altering the position of the assembly supporting the discs and guides and the direction of projection may also be caused to vary continuously by means of an arrangement which can cause the disc/guide assembly to oscillate. The rate at which balls are fed to the discs, the speed and direction of rotation of the discs 74, 76 and their rate of oscillation may be controlled from a remote control panel 170 (Fig. 1) operable by a player.
