thereof. Preferably, in the speci?c form shown, the two
central discs 32 are secured together by spot welding or
brazing or soldering so as to maintain the right angular
crossed relationship of the grooves 34 to grooves 35. One
pair of grooves 35 receives one of the longitudinal bars
15 of frame B. One pair of the grooves 34‘ receives the
transverse shaft 27 of yoke 24. The discs 31, 32 and 33
are clamped together by a clamp bolt 36 extending through

apparatus, the parts are adjusted to the relative positions
one or several of the following adjustments to be made:
(a) the connector unit B can be adjusted longitudinally
along its supporting frame bar 15 to adjust the roller 21
toward and away from the nozzle tip 13; (b) the con
nector unit D can be rotated around the axis of frame
bar 13 to tilt the roller 21 into or out of parallel relation
ship between its axis and the plane of frame B; (c) the
shaft 27 can be slid longitudinally in its clamping grooves
34 to shift the roller 21 along its own axis, transversely
to the major longitudinal axis of the frame B and the 50
major axis of squeeze bottle A, for adjusting the relative
positioning of nozzle tip 13 along the length of roller 21;
and (d) the shaft 27 can be rotated within its clamping
grooves 34 to swing the yoke 24 and roller 21 arcuately
about the axis of shaft 27 to adjust the spacing between
the surface of roller 21 and the nozzle tip 13 in a direction
generally transverse to the plane of frame B.
0perati0n.—ln the use of the apparatus, the squeeze
bottle A is attached to the frame 15 in the manner here
inbefore described, in a position which is adjusted longi
tudinally of the frame B, wherein the nozzle 12 will pro
ject beyond the end cross bar 16 of frame B. in using
the apparatus for applying adhesive to a long narrow
?at surface (such as the ?at margin of a board or trim
strip) disposed in a horizontal plane, or in a vertical
plane with the longitudinal axis of the surface extending
vertically, the parts may be adjusted to the relative po
sitions shown in FIG. 1, with the nozzle 13 approximately
shown in FIGS. 2 and 4, the yoke 24 being adjusted by
rotating the connector unit D around the axis of frame
bar 15' through approximately 180° from the position
shown in FIG. 1 to the position shown in FIG. 2, thus
reversing the position of roller 21, end for end, with re
spect to the frame B so that the receiving shoulder 39 of
nose 29 faces the nozzle tip 13 (insofar as the relation
ship between FTGS. l and 2 is concerned, the frame B
and bottle A have been reversed with respect to the roller
unit C and the connector unit D). The shaft 27 is then
slid longitudinally with respect to the connector unit D
until the nozzle tip 13 is in a position registering radially
with the receiving shoulder 30. The yoke 24 is then rotat
ed about the axis of shaft 27 to bring the nozzle tip 13
and receiving shoulder ‘3% in close proximity as shown in
FIG. 4 so that, when the apparatus is positioned with
the nose 2A9) directed upwardly the nozzle tip 13 will be
directly over the receiving shoulder 30 and in close
proximity thereto for directly delivering the liquid onto
the shoulder as the shoulder revolves. Thus the liquid
is deposited around the circumference of shoulder 36 and
will ?ow downwardly therefrom by gravity onto the
cylindrical surface 21 of the roller toward the lower end
of the roller. Before the liquid is allowed to drip from
the lower end of the roller however, it is spread upon the
receiving surface 49.
