Title: A device for playing a game of skill
IPC: A63B65/12
Filed: 1945-09-17
Abstract: 599,117. Game apparatus. CRAYMER, H. J. Sept. 17, 1945, No. 23979. [Classes 132 (ii) and 132 (iii)] A device for playing a game comprises a wheel mounted on a spindle, a weight or mass mounted on the spindle and spring means acting between the spindle and the weight or the wheel so that when the wheel is propelled the tension of the spring is increased until it overcomes the propelling force and causes the wheel to reverse. As shown a wheel 1 consisting of two end discs spaced by a ring member has a spindle 2 upon which is rotatably mounted a weight 4 by means of a U-shaped member 12, the weight 4 having a band 9 one end of which is doubled back to form a member 10 to which is secured a spring 11. The other end of the spring 11 is attached to a cord 6 leading to the spindle 2 to which it is anchored. On propelling the wheel the cord 6 is wound up on the spindle 2 so tensioning the spring 17 until such time as the reaction of the spring overcomes the propelling force and reverses the rolling of the wheel. Fig. 4 shows one means of playing the game. The wheel 1 is propelled by a cue 17 along an alleyway 13 and the object of the game is to propel the wheel with sufficient force as to, say, make it pass one of the flags 16 but stop short of the succeeding flag.

Title: Method and machine for knitting tubular fabric
IPC: D04B9/46
Filed: 1961-07-04
Abstract: 940,846. Knitting machines. DRAPER CORPORATION. July 4,1961 [July 18, 1960], No. 24082/61. Heading D1C. In knitting tubular fabric on a circular knitting machine, the body yarn is drawn, by means of a flopper cam 40, behind the nibs 39 of sinkers which cast off previously formed needle loops and cause the newly drawn sinker loops to pass from the back to the throat of the sinkers, the fabric being fashioned by progressively decreasing the stitch length and withdrawing outwardly the casting off point of the sinkers. As shown, in a machine with fixed needle cams, the cylinder 22 is vertically movable by cam controlled means acting on the cylinder support 23. The sinker cap 26 is urged downwardly to hold the cylinder in contact with the support 23 whose downward movement is limited by an adjustable stop member 37. Before the body yarn is drawn behind the sinker nibs 39, a cam 41 withdraws the sinkers to cause newly formed loops to pass from the backs into the throats thereof. Cam 40 and a casting off cam 42 underlying it are pivoted to the sinker cap and are both spring-biased outwardly. Ears 48, 49 on cams 40, 42 carry pins 50, 51 engaged by slidable rods 53, 58 actuated by Bowden cables operated by bell crank levers 57, 61 operated by a pattern disc 69. A main pattern drum 62 is moved periodically by a pawl 63 and ratchet 64 controlled by pattern chain 65 which is ratcheted continuously in the same direction by pawl 66 and ratchet 67. An independent auxiliary pattern drum 68 coaxial with drum 62 made up of pattern discs 69 with frangible butts is moved by a ratchet 73 and pawl 74. Pawls 74 and 66 are carried on the arms 76 and 78 of a continuously oscillated bell crank lever. Pawl 74 is inactivated through a linkage when lugs 88 are absent from the pattern chain and, when active, may be effective over only part of its stroke as controlled through a linkage operated by one of the discs 69. Pawl 66 acts during the withdrawal stroke of pawls 63, 74, the latter being operated simultaneously unless one or both is wholly or partly inactivated. One arm 100 of a bell crank lever engages a vertically adjustable sleeve member 101 and the other arm 104 engages the end of an adjustable member 105 fixed to an end of cable 60. Thus as cylinder support 23 moves intermittently downwardly cam 42 will be withdrawn outwardly of the cylinder. Specifications 586, 770, 600, 921 and U.S.A. Specifications 2, 217, 022, 2, 422, 568, 2, 827, 780 and 2, 927, 447 are referred to.

Title: Improvements in or relating to time-element electric relays

Filed: 1939-08-31
Abstract: 532,441. Electromagnetic relays; actuation of switches. GENERAL RAILWAY SIGNAL CO. Aug. 31, 1939, No. 25001. Convention date, Oct. 14, 1938. [Class 38 (v)] In a time-element relay, closure of contacts 5' energizes coils of an electromagnet so as to cause its armature 102, 103 to move clockwise from a central position to bring a gear wheel 114 carried by the armature into engagement with a wheel 118 driven by a motor M<1> ; after a pre-determined time a pin 119 on the wheel 114 causes the actuation of contacts which energize other windings causing the armature to move counter-clockwise, the motor to be stopped, and a circuit 134 closed. In the form shown, the windings first energized are the windings 99, 100 and the clockwise movement of the armature closes contacts 113 in the circuit to the motor M<1>. The winding 100 though shown at the side is really situated behind the winding 99. The pin 119 by engaging a fork 124 controlled by a spring toggle closes contacts 120. 122 completing a circuit to a coil 96 which opposes the coils 99, 100 and attracts the arm 102 of the armature to a pole piece 104, With the disengagement of the cogwheels 114, 118 the pin 19 returns to its original position under the action of a spring 131 operating the fork 124 and its controlled contacts back to their original position. The controlled circuit 134 is now completed since contacts 109, 111 have been closed by the armature and the closure of contacts 108, 110 puts the two coils 96, 95 in series to maintain the armature in its new position while the opening of contacts 108, 112 opens the circuits of coils 99, 100. On opening switch 5<1> all coils are deenergized and the armature returns to its original central position. The whole arrangement of contacts and operating fork 120-124 is rotatable about the axis 115 to vary the time interval. In a modified form of invention, Figs. 1, 2 (not shown), the two top windings are first energized but produce the same result since the air gap at 103 is arranged to be small. Later the two bottom windings are energized and oppose the top windings. The pin 119 also operates spring contacts directly. In a third form, shown diagrammatically in Fig. 7, the gearwheel 136 instead of carrying a pin carries an arm 140 which moves down so as eventually to engage a projection 144 on a ratchet wheel 142 carrying an arm 145 engaging a contact-operating member 147. Contact is thus broken at 152 and made at 158 resulting in the armature moving as in the Fig. 3 construction and de-energizing the motor and moving the gears 135, 136 out of mesh. A spring 138 returns the wheel 136 to its original position and only when it reaches this is a spring pawl 141 lifted from the ratchet wheel 142 allowing this to move back to restore the contacts 152; 151 to their original positions and making the controlled circuit. Practical embodiments of the invention are described and illustrated. Specification 526,930, [Group XXXV], is referred to.

The remote control gear may be operated by compressed air, vacuum, or hydraulic means; or a make-and-break switch operable by push button switches at various points in the building or by the movement of the safety curtain in the case of a, theatre may be provided. A fan A delivers air at ceiling level through apertures in a duct J, first passing it through an air washer B which may include a heater. A fan D is provided for extracting air at ceiling level. Under winter conditions, the fan A is also caused to extract air from the building through a duct K and to re-circulate it, together with fresh air, and the effect of operating the switch H, for instance by the falling of the safety curtain, is to stop the fan A and start the fan D. Under summer conditions, the fan A does not extract air from the enclosure, a fan E being employed for this purpose and valves b<1>, e<2> in the duct are closed and open respectively. The fall of the curtain in this case causes the fan A and fan E to stop and the fan D to start. On the curtain rising normal ventilation is restored. An extraction fan F is also provided above the stage, and this is so connected that the fans A, D, E cannot be started until the fan F is running.
