Title: Improvements in Syringes for Surgical and like purposes.
Inventor: MCGOWAN JOHN POOL
IPC: A61M5/31
Filed: 1916-05-17
Abstract: 107,214. McGowan, J. P. May 17, 1916. Syringes.-A syringe for surgical injection, for the removal of fluid from the body, for transfusion of blood, or for measuring small doses for filling ampoules, comprises a barrel A having inlet and outlet apertures f, h and an elongated piston B having a longitudinal groove e, Figs. 1 and 3, adapted to be turned so as to register with either the inlet or the outlet passage. A passage k in communication with the outlet h terminates in a connexion m for the syringe nozzle &c. The piston-rod D is graduated and carries an adjustable rider n so that the stroke of the piston may be varied. The piston-rod D is semi-circular in cross section and may be turned so that its flat side is guided by either of the flat surfaces of a metal quadrant G, Figs. 1 and 4, attached to the cover F of the barrel. Figs. 6 and 9 show a modification in which three inlet openings are provided and in which a square piston-rod D works in a collar K carrying springs L engaging notches N on the rim of the barrel cover F so that the groove in the piston may be brought into register with any one of the three inlets or with the outlet opening. Fig. 7 shows a coupling whereby a capsule A<11> may be connected to the nipple g, Fig. 3, of the inlet aperture of the syringe. The coupling comprises a cylindrical metal casing A<1> with a screw-on lid B<1> and enclosing a perforated block of indiarubber F<1>. The bottom of the box is perforated by a tube E' adapted to engage the nipple g and the lid B' is formed with an aperture through which the end of a capsule may be passed to engage in the perforated rubber block. Apertures G' in the casing allow expansion of the rubber. The syringe barrel may be formed of metal as shown, or of glass or silica in which case the inlet and outlet apertures would be bored through the barrel and would connect with mounts carried on a metal collar cemented to the barrel.

Title: Improvements in or relating to double-barrel guns
IPC: F41A19/20
Filed: 1930-03-04
Abstract: 350,430. Trigger mechanism for double-barrelled guns. CHURCHILL, R., Orange Street Gunworks, Leicester Square, London. March 4, 1930, No. 7102. [Class 119.] Improved mechanism is provided to enable the two barrels to be fired in succession by one trigger or the other according to which barrel is to be fired first. The triggers are formed with webs 10 and pivoted with a pawl 12 on a bracket 9 at 10<1>. A slide 1 is mounted in the bracket and is linked to the end of a lever 3. The pawl 12 rests by a transverse pin 16 on the top .of the trigger webs 10 and can engage with teeth 13, 14 on the top of the slide 1, which has a transverse pin 2 capable of engagement with projections 19, 20 in slots in the trigger webs 10. When the top lever 8 is turned to break the gun open, the locking bolt 7 pushes the lever 3 and the slide 1 back, and this is held back by the pawl 12 falling in front of the tooth 13. After the gun has been loaded and closed, either barrel can be fired by the appropriate trigger. The trigger lifts the pawl 12 off the tooth 13, and the slide 1 is moved forward by the lever 3 under the influence of a spring 6 until the pin 2 bears against the projection 19. The release of the trigger allows the pin 2 to slip past the projection 19 after which the tooth 14 is caught by the pawl 12. The involuntary pull on the trigger causes the lifting of the pawl 12 from the tooth 14, whereupon the slide 1 again moves forward until the pin 2 is stopped by the projection 20, past which it slips when the trigger is released. When the slide 1 then reaches its foremost position, a catch 22 thereon fits into notches 21 in the trigger webs and couples the two triggers together. The next pull of the same trigger as before will therefore fire the second barrel. The triggers operate on sears 32. For ordinary independent action of the triggers, the slide 1 is put out of action by being held back by a catch 27 adapted to be set by a thumb-piece 31.

Title: Improved step-by-step actuated electric switch mechanism
IPC: H01H63/22
Filed: 1941-06-05
Abstract: 556,934. Electromagnetic switches. LANDIS & GYR SOC. ANON. June 5, 1941, No. 7107. Convention date, May 10, 1940. [Class 38 (v)] Relates to an electromagnetic step-by-step switch in which the reciprocation of an armature 1 is converted into unidirectional rotation of a wheel 10 and the wheel is fed forward during both the energization and the de-energization of the magnet 2. Fig. 1 shows a known form in which the armature 1, biased by a spring 3, rocks a rod 5 which in turn rocks a lever 6 about its pivot 8 and pins 9 by engaging inclined surfaces 11 on the wheel 10 moves it half a tooth forward for each to or fro movement of the lever 6. The wheel 10 drives another wheel 13 with half the number of teeth and the teeth 15 operate contacts 16, 17. In accordance with the invention another toothed wheel 18 moves round with the wheel 13 and in Fig. 3 a contact spring 27 in addition to engaging the teeth 15 of the wheel 13 has an end portion 28 which engages this toothed wheel 18. The wheels 13, 18 move forward a quarter tooth at each energization or de-energization of the magnet 2 and the teeth 18 serve to hold the spring 27 in the central position shown when the wheels have advanced half a tooth and the spring 27 is no longer supported by a tooth 15. In the two other possible positions of the switch the contact 21 on the spring 27 engages the contact 22 or 23. The arrangement is such that a momentary energization of the magnet 2 causes a change over of circuits to be effected, while an extended energization will switch off both circuits. In a further modification the central contact spring engages the wheel 13 only, the other wheel 18 being engaged by one of the other contact springs.
