Tactical flyers ensemble

A tactical flyers ensemble includes a breathable full pressure half suit (“FPHS”) bladder worn as an undergarment beneath a coverall. The coverall has a lower section specially adapted to most effectively constrain the FPHS when the latter is pressurized under flight conditions. Although thus adapted, the coverall remains fully utilitarian and can be worn with or without the FPHS under conditions other than those immediately preparatory to or during actual flight.

Partial pressure cuff seal for utilization in a full pressure suit

A cuff seal utilized in a portion of a full pressure suit which envelopes a limb of a wearers body, the full pressure suit defining at least one full pressure compartment. The cuff seal includes a gas impermeable outer sheath configured to envelope a portion of the limb, the sheath having a first end in pressurized communication with the full pressure compartment, and a second end having an opening through which a portion of said limb exteriorly protrudes from the interior of the full pressure compartment. A gas impermeable inner sleeve is provided having an outer end, an intermediate section and an inner end disposed within the sheath, the outer end of the sleeve being joined in a sealed relationship to the interior of the sheath proximate to the second end, and the intermediate section of the sleeve being adapted to surround and coact in a sealed relationship with a portion of the limb. The sleeve is therefor adapted to interiorly seal the full pressure compartment from the opening to the exterior of the suit when donned by the wearer.

Improvements in Electrical Winding Mechanism and Switches connected therewith.

16,210. Du Bois, E. July 21. Winding mechanism and apparatus; overwinding, preventing. - In electrically - wound clockwork mechanism for time switches and other purposes, consisting essentially of an intermittently-energized electromagnet the armature of which winds up the mainspring through a ratchet and pawl, means are provided for preventing stoppage of the clock when the current is accidentally cut off. In order to avoid overwinding, the mainspring is either allowed to slip when fully wound, or a second spring or a weight for operating a heavy switch &c. may be wound up by the further movement of the armature. The pivoted armature 2, Fig. 1, of the electromagnet 1 winds up the mainspring contained within the barrel 7 by means of a pawl 5 and ratchet-wheel 6. A current is sent at intervals through the electromagnet by the closing of contacts 12, 13, which is effected by a pawl 15 on a lever 10 provided with a pin 9 which bears upon a snail 8 driven by the clock mechanism. An adjustable projection 18<a>, Fig. 8, may be arranged on the radial edge of the snail to arrest the downward movement of the lever 10 and thus maintain the contacts closed for a short time. Three methods of preventing overwinding are described. (1) An auxiliary ratchet-wheel 19 is held by a spring- pressed click 20 which allows the ratchet-wheel to slip when the tension on the spring increases considerably. (2) The pawl 5 consists of two spring-controlled members a, b, Fig. 2, arranged in different planes. The member a drives the ratchet-wheel 6 until the mainspring is fully wound, when the pawl turns upon its pivot against the stop 25, allowing the member b to drive the ratchet-wheel 22 of a second mainspring. (3) The inner surface of the barrel 7, Fig. 4, is provided with notches 27 which engage with the end 29 of a strong blade-spring 28 having the mainspring attached thereto. The end 29 projects through a slot 30 in the cover-plate of the barrel, on which is loosely mounted a ...

Improvements in Coin Mechanism specially applicable for Electricity and other Meters.

14,601. Du Bois, E. June 30. Actuating-mechanism ; coin action.-According to the arrangement shown in Fig. 1, the coin, dropped down a shoot 1, momentarily overbalances a lever 2, which, by means of a hook 5, brings down a second lever 7, and, by means of an arm 13, advances a pair of star-wheels 15, 21, so that an arm 17 on their shaft leaves a detent 11 free to hold the second lever by engaging a lug 12. The second lever constitutes a starting and stopping lever for a meter or motor, which runs till a cam 23 allows a lever 18<a> to reverse the star-wheel, so making the arm 17 detach the detent 11, whereupon the starting-lever rises again. The starwheel 15, on which the coin-lever 2 acts, has one tooth suppressed in order to limit the advance by a number of coins to one revolution. In the arrangement shown in Fig. 4, the coin disengages a detent 30 from a cam 33, which is turned by a handle in order to operate the first lever 2. In both arrangements, the detent 11 may be disengaged by an electromagnet, the circuit of which is completed by the arm 17. Coin-discharging mechanism.-Either the lever 2, Fig. 1, sinks till the coin rolls off, or the detent 30, Fig. 4, being under the control of the cam 33, tips the coin under a bridge 37. Electricity, supplying; gas meters; liquid meters. -For the supply of electricity, the starting-lever 7 either dips into two mercury wells 9, Fig. 1, or bridges two terminals 41, Fig. 4, and, for the supply of fluids, it opens a valve. Fraud, preventing.-In the arrangement shown in Fig. 4, the circuit must be also closed by a switch 42, 43, which ensures the cam being turned back to its initial position.

Improvements in Coin Mechanism specially applicable for Electricity and other Meters.

14,602. Du Bois, E. June 30. Actuating-mechanism ; coin action.-According to the arrangement shown in Fig. 1, the coin, dropped down a shoot 1, momentarily overbalances a lever 2, which, by means of a hook 5, brings down a starting and stopping lever 7, and, by means of an arm 12, operates a ratchet lever 13 turning a notched disc 16. The notched disc 16 is associated with another disc 18, which has one more notch and is driven by a motor or meter. This disc having a pawl 20 to drive the first disc, the pair turn till coincident notches are presented to a blade 24 on the starting and stopping lever. The notched wheels may be driven electromagnetically. As a modification, the coin-lever 2 is actuated by a cam with a handle, from which the coin disengages a detent. To reduce the pressure of the starting- lever 7 on the discs, the arrangement shown in Fig. 8 is adopted. The starting - lever 7 is subsidiary to a main starting-lever 7<a>, and, in returning to the notches, it completes the circuit of an electromagnet 48, which disengages a latch 47 from the main lever. Electricity, supplying; gas meters; liquid meters. -The starting and stopping lever either switches current on and off or opens and closes a valve. Coin-discharging mechanism.-The coin lever 2 sinks till the coin rolls off. The detent for the cam, which is turned by hand to operate the lever, tips, as the cam turns, till the coin rolls off. Fraud, preventing.-The cam must be turned back to its initial position to make the circuit complete.
