Yesterizer

The Yesterizer is a machine, used only in Speed Dating by assistants with Yesterization Qualifications to send patients who arrive via Time Portals back to their correct eras. Clockwise-above-Thyme is the only hospital where this is possible, as such the machine is not available in other hospitals.

Appearance
The machine sits on a round-cornered rectangular bluish-grey base. In the centre is a gangway, in bare metal, flanked by brass edges. Three darker metal steps lead up to it, separated from the main walkway by a strip of yellow-and-black hazard stripes. Running the length of this on both sides are light metal handrails, on the centre of which is a raiseable barrier, bearing the same hazard stripes. Parallel to the gangway section on each side is a long, round-cornered rectangular plate in the same metal as the base, with light blue illuminated edging, in the centre of which is mounted a tesla coil with a brass rod in the centre, and light metal rings, also with an illuminated base. These two plates are connected to the gangway by plum-coloured tubing.

A vertical section at the end of the gangway features a huge brass cog, which is bracketed on the back by a large dark blue ring, with a smaller equivalent on the front. A smaller light metal ring with an illuminated chevron is attached to the front, able to rotate slightly, so as to be able to select one of the three circular icons on the top section, in dark blue with light metal edgings, each bearing a symbol representing an historical era that the patient may be sent to. On top of the machine is a silver hammer, flanked on both sides by two large red bells, giving the impression of an alarm clock.

Two more lengths of plum-coloured tubing protrude from the back of the machine, running along the right-hand side to a separate console. The main body of this is dark blue, and an irregular pentagonal shape, flanked on both sides by large brass plates. An additional brass section on the right is home to a large lever with a red handle. The left-hand side of the console itself features a spinning hourglass, with a large light blue button to the right, blow which is a red rectangular slider set into a grove running the width of the entire console.

Function
Approaching the steps leading up to the gangway, the patient will wait while the assistant uses the light blue button to activate the Yeterizer's time warp. A larger version of the one in the centre of a Time portal, it will burst into life, with two light blue clock hands rotating in the centre. As the patient proceeds along the gangway, stopping at the barrier, the assistant will pull the lever and use the red slider in order to select the relevant time period, while the hourglass spins.

The chevron on the Yesterizer will move, eventually settling on the correct icon, while will then illuminate, and the assistant will push the lever back to its original position, the final chevron locked, causing the barrier to rise. With the assistant's encouragement, the patient will step forward, and take a leap into the time warp, on their way home, at which point the machine will close down the gateway.

Maintenance
The Yesterizer loses 10% of its maintenance gauge with each use. Once the gauge falls below 50%, a Janitor will automatically be called to repair it. A janitor can be summoned manually by selecting the machine and pressing.

Should the maintenance gauge fall below 15%, the machine will catch fire. A janitor will need to use an Extinguisher to put this out before the gauge reaches zero; if it is allowed to do so, the machine will explode, leaving wreckage which must be sold and replaced with a new machine before the room can resume functioning.
