Hi,
You can either use CAR or Class based policing on the ingress interface.

If the 1841 is running a later IOS image that supports CBWFQ, you could do it as follows:
pseudo-config
class-map FTP
match protocol ftp
policy-map CBWFQ
class FTP
bandwidth 1mb
police 1mb
int s0
service-policy out CBWFQ
I'm suggesting using CBWFQ, which will allow you to easily expand QoS if you so desire.
You could also do the above with a shape command instead of police. The policier will drop all FTP traffic above 1 Mb, a shaper will queue it and to keep FTP from exceeding 1 Mb.
You could also not limit FTP bandwidth, but just prioritize to only use excess bandwidth.
e.g.
policy-map CBWFQ
class FTP
bandwidth percent 1
