longer ?nger member 26 may be slid in the open

tions so that different lengths of the ?nger mem
bers project from the block member I8. After
the ?nger members have been'slid to the desired

members, and the longitudinal member having
the open space therein, the straight edge mem

widths and therefore, in trimming off this margin,

is turned outwardly.
Therefore, each ?nger
member may be slid or moved relative to each
block member upon which it is carried so as to
extend apre-determined distance outwardly from
the block member and may be clamped securely
50 in
that position. As each ?nger member is sep
arately clamped, each‘ may be set at a diiferent
length from the block member l8 and from the
straight edge member [3 upon which the block
" member I8 is mounted.
The projecting portions
25 and 2'! of the finger members 24 and 26 respec
tively extend down su?iciently to engage the up
wardly projecting portion of the longitudinal
member l5. It is seen that when the projecting
60 portion‘ 25 is pushed up into engagement with
‘the longitudinal member that the straight edge
member 13' will be held at one distance from the
longitudinal member l5 and that when the pro
jecting portion 21 is pushed up into engagement
65 with. the longitudinal member that the straight
edge member l3 will be held at another distance
from the longitudinal member, the said distances
depending upon‘ the relative lengths of the ?nger
members 24 and 26 extending out from the block

wall paper 3| are then brought up together to
'meet at the point or junction'32 so as to form a
folded strip of material or paper with the paste
enclosed and the printed part of the paper on 50
the'outside. As the paper has been folded double,
any inaccuracy or error in cutting the margin
off perfectly straight and longitudinally of the
strip of paper will be magni?ed. It is essential
that the margins be trimmed off perfectly true so 55
that when the paper is hung upon the walls the
adjoining edges of the'strips of wallpaper will be
perfectly square and parallel throughout their
length. Therefore, great care must be exercised
in aligning the straight edge member along the 60
strip of wallpaper so that the cutter will trim off
a margin of equal width throughout its length.
It is also desirable that such proper trimming of
the margin be done with a minimum of effort
and time so that the various strips of wallpaper 65
may be trimmed and hung in rapid succession
without a large number of adjustments, measur
ing, and shifting of the straight edge member.
All of the rolls of wallpaper of the selected type
will have all the margins on one edge of one width 70
and all the margins on the other edge of another
width so that margin 33 and margin 34 will be
uniformly the same on all the strips of wallpaper
which permit the projecting portion 21 to be
on a certain job to be done as having been uni

To trim off the narrower margin 33, the strip of
wallpaper is swung around on the table surface
I i so that the other longitudinal edge of the strip
25 of wallpaper abuts the longitudinal member as
rial on a table surface, comprising, in combina

shown in Figure 2. For determining the position
of the straight edge member H1 in this operation,
the shorter ?nger members 24 are utilized. In
order to bring them into engagement with the
longitudinal member without having to unclamp
the longer ?nger members 26, the straight edge
member I3 is shifted so that the projecting por
tion 2‘! of each longer ?nger member 26 is moved
through the open spaces l1, thus permitting the
35 shorter ?nger members 24 to engage the longi
tudinal member. The length of the shorter ?nger
members 24 are similarly set so that the straight
edge member i3 is held in proper position upon
the wallpaper 3| so that the margin 33 will be
40 trimmed off at the proper width and at a uniform
width throughout its length.
Each strip of wallpaper having the same mar
gins 33 and 34 may thus be trimmed without re
setting my guide device so that the trimming
45 may be done rapidly, accurately, and with a mini
mum of adjustments and effort.
Although I have described my invention with
a certain degree of particularity, it is understood
that the present disclosure has been made only
50 by way of example and that numerous changes
in the details of construction and the combination
and arrangement of parts may be resorted to
without departing from the spirit and the scope
of the invention as hereinafter claimed.
