from said roller, from and to the sheets, &c.,

to be pasted.

It further consists of the combination and arrangement of parts hereinafter set forth and claimed.

Figure 1 represents a perspective view of a pasting device embodying myinvention. Fig. 2 represents a vertical section thereof. Fig. 3 represents a perspective view of a detached portion thereof.

Similar letters of reference indicate corre Sponding parts in all the figures.

Referring to the drawings: A designates a trough or box for containing-paste or other l adhesive material, and B designates'a roller which is mounted on said trough and dips into the same. l p

C designates a rising and falling table on which is placed the sheets to be pasted, the

. same having depending from vit the rods D,

which pass freelythrough bosses E on the under side of the bed F, and have connected with them the weighted cords G or in lieu thereof coiled or other springs, whereby the vtendency of the table is to rise and thus elevatethe sheets, the bed F and trough A being supported on a bench'F2 in a suitable manner.l

Mounted on the pieces F which rise from the bed F, is the paster Gf, which consists of a cross bar, strip Aor brushf'H, which extends transverselyover thesheets on the table, and is adapted to be broughtinto contact with the uppersheet thereof,rand apply pastef thereto, as will be hereinafter more fully described, said bar H being connected with a shaft. J, whose bearings are on the slotted ears K, the latter being connected with the Same.

pieces F by means of bolts L whereby the har may be adjusted in relation yto the periphery of Vthe roller B andthe sheets on` the table.V

The shaft J' carries the pinion M which meshes with the pinion N on the shaft P of the roller B, said shaft having also secured to it ythe driving pulley Q to which power is communicated inan'y suitable manner.

In orderto limit the ascent of the sheets on the table, there are secured to the upright R on the trough or bed F, the hooks S, whose upper horizontal limbs overhang the edge of the top sheet of the pile-on the table C and act as stops, the effect of which is evident. T designates a scraper or wiper formed of slotted side pieces U, a cross bar V, and longitudinally-extending end pieces W. f The pieces U are connected with the pieces F by means of bolts X, whereby the scraper may be set nearer to or farther from the roller B, it being seen that the'bar V is adapted to receive the surplus paste from the periphery of said roller, and the end pieces from the sidesof the same, within said periphery, so that said periphery is nicely and uniformly supplied with paste, in which condition the latter is taken-off by the bar H of the paster. The operation is as follows: The roller Bis rotated, and the paster 'is operated by the bar His cut away or recessed as at S', at

places in the paths of the tops of the hooks S,

so as to permit said bar to rotate without linv terference ofthe latter. Having thus described my invention, what I claim asnew, anddesire tosecure byLetters Patent, isf

2. A pasting device having a trough with a .roller dipping therein, a rising and falling tablega paster with a rocking shaft having a ro pinion meshing with a pinion on the roller shaft, and a scraper for said roller, said parts being combined substantially as described.

3. A pasting device having a roller, a rotary paster, an ascending table, and stops for limr5 iting the ascent of the latter, said paster being formed with a recess for clearing said stops, substantially as described.
