1 Claim. (Cl. 191-133)
The present invention relates to a ?lm feeding and sup
port assembly and more particularly to an adjustable sup
2b at any desired spacing.
Framepiece 2b contains spindles 6 and 8 on which
spools may be mounted. Referring to FIG. 2, a detailed
view of the present invention is shown to illustrate how
a variety of diiferent width ?lm spools may be mounted
within framepieces 2a and 2b. Framepiece 2b is spaced
along connecting bar‘ 2g an appropriate distance in ac
cordance with the particular width of the ?lm spools to

feet in length and as wide as 9 inches in width. A prob 20 revolutional movement is transmitted to spool 7. There

It was stated hereinabove that the entire spool retaining
through the typewriter is being moved in the lateral di
25 carriage 2, including framepieces 2a and 2b, connecting
rection with the typewriter platen.
An object of the present invention is to provide a ?lm
feeding and support assembly for movably supporting
bar 2g, and mounted spools 5 and 7 is free to move along
bars 1a and 1b. A coupling means 3 is provided to trans
various size ?lm spools proximate to a printing device.
According to the present invention a feeding and sup
mit the lateral motion of platen 4a to spool retaining
port assembly is provided which is adjustable for support

Coupling means 3 includes a vertical bar 3b rigidly con
ing various size ?lm spools, the ?lm from which is dis
pensed to a proximately located printing device such as
a typewriter. The feeding and support assembly is mov
able in response to movements of the typewriter platen
through which the ?lm is threaded.
The present invention is explained in reference to the
drawings in which:
FIG. 1 is a perspective view of a preferred embodi—
ment of a feeding and support assembly following the
principles of the present invention; and
FIG. 2 is a detail view of the assembly of FIG. 1 show
ing how ?lm spools are mounted thereon.
Referring to FIG. 1, a feeding and support assembly
for supporting a medium on which printing is to be
performed relative to a printing device ‘4 is shown com
prising a support means 1, a medium retaining means 2
mounted on support means 1 for relative movement

nected to bearing assembly 2d and a forked bar 3a rigidly
connected to platen 4a. During operation of the system
bar 3b is positioned within the tines of forked bar 3a so
35 that lateral movements of platen 4a will be transmitted
through bar 3b to bearing assembly 2d, thereby moving
spool retaining carriage 2 in accordance with movements
of platen 4a. The linear bearings within assemblies 2c,
2d, 22, and 2]‘ are designed to have a very low co
40 efficient of friction, so it may be desirable in some in
stances to provide damping means, such as dash-pots,
within the bearing assemblies to prevent spool retaining
carriage 2 from a tendency to overshoot.
Printing means 4 is mounted on two tracks 41; and 40
for easy disengagement. When belt 30 is disconnected
from platen 4a and printing means 4 is moved forward
on tracks 41; and 4c, bar 3b is removed from between the
tines of forked bar 311 and printing device 4 and spool
thereon, and means 3 coupling medium retaining means
2 to the printing device so that medium retaining means 2 50 retaining carriage 2 may be moved independently of
