PASTING-MAGHIANE.

$PECIFICATION forming part of Letters latent No. 656,355, dated August 21, 1900.

Application filed April 7, 1900.

T0 wZZ whom it may conceive:

Be it known that I, ARTHUR IJACOBS, a citizen of the United States, residing atI-Iartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Pasting-Machines, of which the following is a specification.

This invention relates to those machines which are employed for distributing paste, glue, or similar cementing or adhesive substances upon sheets of paper, cloth, or the like thinfieXible material.

The object of the invention is to provide a simple, convenient, and cheap machine of this nature which is particularly adapted for evenly distributing pasteupon sheets of paper designed to be used for covering the boards of the cases of books. 1

Figure 1 of the drawings shows a plan of the machine. Fig. 2 is a view of the back side of the machine. Fig. 3 is a vertical section on the plane indicated by the broken ing at one end of the machine.

The bed 1 and the standards 2 at each end of the bed are preferably cast integral of iron. An adjustable bracket 3 is pivoted to the inside of each standard. The upper ends of these brackets are provided with bearings for the 51131114: of the feed-roll 5, while the lower ends of the brackets are adapted to be drawn forwardly by screws 6 and to be pushed back wardly by screws 7, that pass through perfo: rations in lugs 8, that project from the inner walls of the standards. On one end of the feed-roll shaft is a driving-pulley 9, that is adapted to be belted to any source 'of power. This pulley is fastened to or loosened from the shaft by a clutch 10, that is operated by the handle 11. Fixed on the feed-roll shaft adjacent to the clutch is a gear 12, that meshes with a gear 13 on the end of a shaft 14, which bears the distributing-r0ll15. This shaft is supported by the legs 16 of the pastereceptacle-l7in such position that the roll occupies an opening in the bottom of the reoeptacle. The distributing-roll shaft at one end bears a pinion 18, which mesheswith a gear 19, that is in mesh with a gear 20 on the Serial No. 12,010. (No model.)

shaft 21 of the spreading-roll 22, thatis sup ported in the opening in the bottom of the paste-receptacle adjacent to the distributingroll. By means of this gearing the distributing-roll and the spreading-roll are caused to rotate in the same direction. A gate 23 is attached to the under side of the bottom of the paste-receptacle by screws 24, so that it is adjustable toward and from the distributingroll to prevent the leakage of paste past the distributing-roll. This gate is held with its edge just out of contact with the surface of the distributing-roll, so as to prevent the outflow of paste, but permit whatever paste there is on the surface of the distributingroll to pass into the receptacle before it is scraped off. .A scraper 25 is by arms 26 held in contact with the upper part of the distributing-roll to keep the" paste from becoming coated upon that roll. Secured to the inside wall of the paste-receptacle, at the bottom and adjacent to thes preading-roll, is a scraper 27. When the screws 28, that hold this scraper, are loosened, it may be adjusted toward and from the spreading-roll to keep that roll clean and prevents the leakage of paste past it. A

number of curved fingers 29 are secured to p the bottom of the paste-receptacle, so as to bear against the distributing-roll and prevent the pasted material from adhering to the surface of the roll. .The bottoms of the paste-receptacle legs and the tops of the bed-standards are tongued and grooved, so that the parts may be slid to- A gether horizontally, and when in proper position pins 30 are thrust through the tongueand-grooved parts to prevent their lateral displacement. When these pins are withdrawn, the paste-receptacle, with the spreading and distributing rolls and separating-fingers, may be removed for washing and cleaning off the adhesive substance, leaving the feed-roll and the bed in working position. A roll 31 is supported by brackets 32 at a suitable distance from the feed-roll, and around this roll and the feed-roll an apron 33 is arranged to pass. It is preferred that this apron shall'be a single thread wound from one roll to the other and then having its ends joined. The feedroll to carry down from the receptacle but a thin even film of paste. The paste thus evenly spread upon the distributing-roll is distrib uted upon the upper surfaces of thesheets that are passed between the feed-roll and the distributing-roll. These pasted sheets are carried upon the moving apron until they are removed by the operative and used for inclosing the boards of the bookcases. The

feed-roll is adj nsted toward and from the-distributing-roll by means of the screws that engage the ends of the brackets, so that it will correctly feed the thin sheets which are passed through the machine. Large sheets of thin paper may be rapidly passed between the feed-roll and distributing-roll and evenly coat.- ed with the desired quantity of paste. These sheets are employed for covering paper-boards whichare used for book-covers. There isno leakage of paste past the rolls, and the paste is not permitted to become thickly coated upon. the rolls in such manner as toclose the opening between the spreadingand distributingrolls.

The machine is simple to build, convenient to operate, and is easily cleaned.
