having relatively long, ?exible bristles which will
conform readily to the shape of the counter.

the instant machine, in order to prevent the ap

counter at an angle of about 20° to the hori

tacle '42, as will be seen by reference to Fig. 2,
is provided with a rectangular opening 54
through which paste may run onto the bristles
of the brush Hi. The size of the opening 54 may
be controlled in accordance with the viscosity of

to flow through it, by a slide valve 55 having an

that is, the brushes I4 and It, comprises a rotat
able counter holding member 8%) (Fig. 4) and a
rotatable counter clamping member 82. Referring
to Figs. 4 and 7, the counter holding member 80
consists of a substantially V-shaped block 84
which has a substantially V-shaped recess 86 (Fig.
7a), thereby forming a member having diverging
legs joined by a rounded, closed end which con
forms closely in shape to'the molded counter and
along the legs of which the legs of the counter are

slide valve 56 consists of a ?at plate which is
slidable in a groove 5? (Fig. 4) formed in the
the block 84 is situated close to the left side of
upper face of the shelf all. The valve 55 has at
the brush I5 and straddles the shaft 20. A hub
88 having a substantially V -shaped recess 89 (Fig.
one end an upwardly projecting flange fill which
serves in co-operation with a pivoted lever 52 40 6) therein is formed integral with the block and
extends to the left, as seen in Fig. 4, surrounding
to slide the valve to the right or left to open or
the shaft 20, the left end of the hub being sup
close the valve. As will be seen by reference to
Figs. 1 and 2, a plate 64 forming part of the lever
ported for free rotation upon a bearing 90, the
52 and having a bifurcated end 55 is pivoted at
latter being fastened to a crosshead 92 recipro
cable along the base I0. Near the inner end of the
58 to a bracket 1i) fastened to the side of the
block 84, the lower end as seen in Fig. 7, there is
receptacle 42 in such a position that the upper
formed a groove 94 which extends from the open
end of the flange GEE projects into the bifurcation.
The lever 62 is rigidly fastened by screws ‘12 to
ends of the legs of the V-shaped block around
the plate M in a position to lie beside one end of
the outside of the rear rounded end portion
thereof. This groove 94 is adapted to receive an
the receptacle 42,'as seen in Fig. l, and on the
inwardly bent bottom flange 8? of the counter,
upper end of the lever 52 is a pointer which may
thereby to protect it from an application of paste
be moved over a scale 14 marked on the side of
the receptacle. The graduations on the scale
as in the prior machine. A pulley I90 (Fig. 4) is
secured to the hub 8.8 against a ?ange IOI and
represent valve openings for varying conditions
of viscosity. A small knob it formed on the 55 adjacent to the bearing 99, the pulley having a
substantially V-shaped recess 96 therein (Fig. 6)
pointer serves as a hand hold to move the pointer
over the scale in one direction or the other. It
was found that When the valve 56 was closed
the ends of the bristles of the brush M would rub
against the bottom face of the valve and cause
some wear, which is undesirable, and, further
more, when the machine was at rest, the under
surface of the valve would de?ect the bristles
and, if left in this position for any length of
time, a permanent distortion of the ends of the
bristles would be brought about. To avoid this,
a recess ‘l8 (Fig. 2) is formed in the bottom side
of the valve plate 55 and in the shelf M to ac
commodate the projecting ends of the bristles.
A counter 18, as shown in Fig. 8, is preformed
and has diverging legs joined by a rounded back
part, and in the illustrated machine means is
provided for moving the counter, open end ?rst,
in a linear direction to advance one leg between
the brushes I 4 and it until the inner surface
which corresponds to the substantially V-shaped
recess 89 in the hub 88. The pulley I00 provides
means for rotating the hub and to this end a pair
of grooves I02 and HM, formed in the peripheral
surface of the pulley, are adapted to receive the
overlapped opposite ends of a chain I66 (Fig. '7)
which are placed one in each groove and are
pinned therein. At the extreme left end of the
hub 88 (Fig. 4) there is fastened a disk I 88 which
abuts the outer surface of the bearing 90 and,
together with the pulley iilii, prevents axial move
ment of the hub laterally of the bearing 9%}. The
disk I08 has a substantially V-shaped recess I09
therein (Fig. 6) to correspond to the recesses in
the hub 88, the pulley sec, and the V-shaped
block 84. To prevent upward movement of the
hub 88 away from its bearing 9i}, an arcuate flange

the prior machine, to permit movement of the

means, the bearing 90 is made slightly less than

The clamping means ‘82 which cooperates with
the supporting means 80 in holding the counter, 10 may be moved apart against the action of the
springs I42 and I44 to release the counter. When

right-hand side of the brush I6, as viewed in Fig.

the plates are urged together by the springs I42

in the bifurcation I16 of the block and is slidable
coincident with the axis of rotation of the hub 88.
The split bearing H6 is provided with a pair of

a downwardly extending, arm 288 which lies in
the path of the collar 286 and rides over the
latter on thereturn of the crosshead 92. Hence,
when the rod 235 is pulled forward to start the
machine, the collar 285 will engage the arm 288

the lever 282 is moved out of the notch. 0n the
reverse movement of the crosshead from the back
of the machine to the front of the machine, that
\ is, from right to left as seen in Fig. 1, the lever
298 performs a similar function so that the
counter is again rotated as it passes the applica
tor brushes until a screw 305 pushes it down out
‘ of its notch.
In the present machine, in contrast to that de
scribed in the prior application, the counter hold
ing and clamping means are so positioned that
the leg which is being operated upon makes an
angle of approximately 20° to the horizontal, that
3 is, the direction of movement of the counter. In
order to avoid displacement of the counter clamp

the wedge-shaped block H4 is brought into con
tact with the disk 234 at the front of the machine,

through a boss 3“) formed on the disk I58, as will
be seen by reference to Fig. 6. The end of the 10
cating screw 308 is adapted to engage the top sur
face of the horizontal bar 380 and hence to hold
"the counter clamping and supporting means in
the proper position against any tendency to turn.

paste to the outside of the counter was station
