The supports 29, 30 form parts of the shiitable The section 5 includes a rectangular trough 82 section 6. formed of an outwardly inclined front wall it, a The section ii also includes a wiper roll 39 dis 5o rearwardly inclined rear wall M, a pair of verposed transversely of the trough 52. The roll 39 tically disposed side walls l5, iii, a bottom I! and is mounted on a shaft 40 which extends through a normally closed drain IS. The trough l2 has bearings M at the rear ends of a pair of adjustable a series of spaced supporting legs is depending spring controlled positioning devices 2 for the from bottom ll. The trough I2 is of the depth, wiper roll 39. The devices iii are slidably length and width desired and may be empolyed mounted at their front ends in the heads 24' of 5 the supports it. Each of said devices d2 includes a combined stop and adjusting nut :13 at its front end. The shaft do is mounted in the cutouts 22. The shaft t projects from side wall it of the trough and has fixed thereto gear wheel 35. The devices :32 resiliently maintain the wiper roll at a point substantially centrally of front of and against the periphery of a glue applying roll 56 which is of materially greater diameter than roll 33. The said devices 62 act as a safety means in case a foreign solid material is in the glue and comes up between the rolls 53. The roll 16 is carried by a shaft which is journaled in. the cutouts 23 and projects from the sidewall id of the trough. The shaft ll has fixed thereto a gear 68 and a pinion G5. The latter meshes with and drives gear Anchored, to the side wml it? of the trough is a bearing 59 in which is jomnalled a stub shaft 56 carrying a pinion and a pulley 53. The pinion meshes with and drives the gear 48. The pulley is operated from the driv ing connection 5: which leads from motor The section ii not only includes the supports 2%, 3E but also a pair of superposed guide rolls 56 55, a combined material holding and guide roll above and rearwardly of roll 55, a series of spaced parallel pick-up or pick-off fingers 5?, a pair. of connecting rods 58, 59, a holding bar (ill for the fingers 51, a carrier 66 for the fingers 522a platform or table 62 for the material which is to be operated upon, a pair of spring controlled latching members 63 for the supports 2%, 3d, pivots E i for the members 655, aligning inclined cutouts 64', aligning vertical cutouts 65, aligning vertical cutouts 66, and a pair of adjustable closures 6?, each common to a cutout 65 and 66.

The supports 29, 3D consist of forward parts 68, intermediate parts 69 of greater height than parts 68 and rear parts ill of greater height than parts 69. The cutouts 6d, 65 open at the top edges of the parts 69. The cutouts 66 open at the top edges of parts F0. The closures 67 are mounted on the top edges of parts 69 and are adjustably connected to the latter by the retaining screws ll having large heads. The rolls 5d, 55 and 56 are carried by the shafts l2, l3, and M respectively. When the machine is in active position, the roll 50 is arranged over roll 39 and. positioned in prom imity but spaced from the front of roll 15; the roll 55 is arranged over and extends rearwardly from the roll 54; the roll 55 is disposed in spaced relation to the upper portion of the front of roll 46; the roll 56 is arranged above and rearwardly of roll 55 and in spaced relation to the latter; and the roll 56 is positioned over and slightly forward of the vertical median of roll 46, as well as being spaced from the latter. The shafts l2, 13 extend into the inclined cutouts 64. The shaft it is seated in the cutouts 65. The pick-up fingers 5'! are arranged over roll 55 rearwardly of and in proximity to the guide roll 56.

The pick-up fingers are of like form and each consists of a plate 15 gradually increasing in width from rear to front. The forward end 16 of plate 15 inclines rearwardly from its lower to its upper end. The bottom edge ll of plate '15 inclines downwardly from rear to front. The plate 15, in proximity to its rear end, is formed with an opening 78 and between its vertical median and forward end is provided with an opening 19 arranged below opening I8. The side marginal portions of the plate 15 bordering the end 16 are oppositely beveled, as at 80, to form a feathed edge at the forward end of the plate.

The holding bar 60 extends through the openaoecyeo iiuictions g :2 down so fingers.

. elongated in the 2.0 is of length to project y 2. substantial distance beyond the front of the trough The width of platform. is such as to have its sides arranged over the sides of trough i2. The platform is provided. with spa ed legs for seating upon the top edge of the front Wall 23 of trough G2. The platform C2; detechably secured upon the parts by set screws Arranged at the front of the trough i2 and leading to motor is a controlling means B l for the latter.

The outer faces of the sides l5, it of trough l2 are formed with lugs coasting with the latching members 63 for detachably securing the section 6 relative to section 5 in the position shown in Figures 1 and 3. The controlling springs for members 63 are designated 86. The pivots 5d are secured in the parts 68 of supports 29, 38 rearwardly of and in proximity to rod 58. The latching members 63 extend above said parts 68 to be in convenient reach of the attendant.

The material which is to be acted upon is $21- dicated at 3'1. The material is extended between guide rolls 56, 55, picked up and glue applied to one face of the material by roll G6. The roll 56 causes the material to pass towards the pick-up fingers 57 and these latter function to direct the coated material in the manner as shown in Figure 3.

When it is desired to clean roller 46, as well as rollers 56, 55, and 56 and the fingers 5'5, the section 6 is released and swung to the full line position shown in Figure 2. Section 6 is maintained in such position by the rod or bar 59 seating upon the holders 3i, By this arrangement convenient access may be had to those elements of the machine which are to be cleaned.
