Something to keep the place sterile?

Indeed (well very close)

This is an "Antiseptic Machine" - I find it quite incredible actually: -

"Anthony Bell, a surgeon based in Newcastle, patented the design for his device in 1879. The machine was used to make the surrounding air antiseptic. The hammer tapped the base of a small container of medicated powder, rather like an upside down salt shaker. The powder was sprinkled into the path of a fan in the tinned cylinder at the back of the machine. Air from the fan was propelled through a piece of gauze sprayed with carbolic acid. The medicated powder and the carbolic acid combined to rid the air of germs. maker: Bell, Anthony Place made: Newcastle upon Tyne, Newcastle upon Tyne, Tyne and Wear, England, United Kingdom"

Must read the question as well as look at the picture.
Looking at it if you shoot them they will not suffer,

Difficult to know where to post this, but thought this the best.

Firstly R.I.P. Bill - You should have been recognised more.

Quite frankly stunned the first "Computer Mouse" used was pushing 60 years ago!!

The Co-Creator Of The Computer Mouse, William English, Has Died Aged 91.

"The engineer and inventor was born in 1929 in Kentucky and studied electrical engineering at university before joining the US Navy.

He built the first mouse in 1963, using an idea put forward by his colleague Doug Engelbart while the pair were working on early computing.

It would only become commonplace two decades later, when personal home computers became popular.

Mr English's death was confirmed to US media outlets by his wife.

Bill English became the first person to use a mouse when he built the prototype at Mr Engelbart's research project at the Stanford Research Institute.

The idea was Mr Engelbart's, which he described as only being "brief notes" - but the creation was down to Bill English.

His first version was a wooden block with a single button - and underneath, two rolling wheels at 90-degree angles that would record vertical and sideways movement.

"We were working on text editing - the goal was a device that would be able to select characters and words," Mr English told the Computer History Museum in 1999.

In an experiment, the pair asked users to try out the mouse alongside other pointing devices such as a light pen or joystick - and found that the mouse was the clear favourite. They wrote a paper, which was largely ignored for years.

At their 1968 demonstration, the mouse was shown off publicly for the first time - along with video conferencing, word processing, and a form of links similar to what we use on the internet today."

What is it/What was it used for?
Invented by whom & roughly when?

"Clues": -

No, it's not the model for H.G. Wells' "Time Machine".
Entertainment.

Some kind of projector?

Some kind of projector?

Close, but no cigar. The "projector" actually came a little later

[dtaai-maai]

It looks like it's powered by electricity, so early 20th Century?

I'll give you that one - nearer mid 20th century though....

And I should have said the "projector" came a little earlier!

1st laser?

I'm running out of ideas. Looking at the holes I'm guessing it must have something to do with pictures, and probably moving pictures, but it's not a projector... A transmitter of some kind?

Close enough I think - it's the first television camera invented in 1926 by Scottish engineer John Logie Baird.

Obvious what it is, but when and why were these small portals originally used?

^ Funnily enough, I was reading an article about these.....
