Looking for some information on this hammer hand drill

[Cevad58]

I was recently given a carrier bag full of old egg wisk type hand drills. Among the usual suspects was this skeletal hammer drill. The only identifying markings are text that reads:
E-KON-O-ME Patent No.24938

Only ref I could find for E-KON-O-ME was for an antique fruit crate from the 1920’s. Other searches for hand operated hammer or impact drills are all with enclosed workings similar to the old Raw plug types.

Until I discovered the above embossed data I was wondering if it could have been something put together by an apprentice perhaps. I still wonder that and perhaps whoever made it used the above data for fun. Perhaps the Patent number is a birth date or date of completion of project. Maybe it was a prototype but now I‘m obviously clutching at straws.

It does seem more of a home build/one off project than something in mass production. Its blued rather than painted and there are some machining marks in the more visible areas. The handle is cast and there is a smaller casting at the chuck end.

Appreciate any info or pointers

Thanks

Probably a UK patent number; can't those be looked up online?

I did have a look but not exhaustively as it was all a bit convoluted when I had a dabble but it was late too so perhaps I should have another look. Its getting on a bit being only a 5 digit number if is a patent number.

I've since stripped it down and the more I look the less it looks mass produced, more of a "homer".

Can't help with identification, but that's the sort of lovely old tool I'd hang up as artwork on the wall - it looks good & a great design. Yes my better half goes mad at me for sticking things on the walls

"E-KON-O-ME" ? Sounds American . . . They have always been fond of "ciute" homophons
