MACHINE FOR THE MANUFACTURE OF CARD AND COLLAR BOARD.

SPECIFICATION forming part of Letters Patent No. 234,266, dated November 9, 1880.

' Application filed September 29, 1880. (No model.)

To all whom 'it may concern Beit known that I, CHARLES M. GAGE, of Nashua, county of Hillsborough, State of New Hampshire, have invented an Improvement in Machines for the Manufacture of Card and Collar Board, of which the following description, n connection with the accompanying drawlngs, 1s a specification.

This invention relates to machines for the manufacture of card and collar board from webs of paper or paper and cloth combined.

In this my machine I submerge the web or webs which are to form the central part of the card or collar board in paste or cement contained in a trough located in advance of a pair of rollers that act to draw the web or webs from a roll of paper through the trough, the said rollers then pressing the webs closely together where two or more webs have been pasted, thus forming one compound web, and the said rollers also, by the degree of their pressure upon the web or webs passed between them, determine or regulate the amount of paste or cement left in the web or webs.

One, two, or more webs may be drawn through the paste-trough by the rollers, but the web leavlng the said rollers is a single one, more or less thick, and such web constitutes the body for the card or other board. This bodyweb, pasted on both sides, after passing the drlvlng or feeding rollers, 1's surface-finished upon both sides with paper, or, if desired, with cloth, or with,, paper on one side and cloth on the other side, this depending upon the use to which the board is to be put.

Figure 1 represents, in plan view, a machine for the production of card or collar board in accordance with my invention; Fig. 2, a side elevation thereof, the pressing-rollers beingin section, a part of the driving-gear and beltpulleys being removed; and Fig.3, a detail of the paste or cement trough with its rollers to submerge the web or webs of paper in the paste therein.

The frame-work a b of the machine has a series of standards or brackets to support the different movable parts of the machine.

The trough c, to contain the paste or cement, is located in front of the rolls r 1", containing the web or webs e 0, one, two, or more of which lar board. This trough, partially filled with paste or cement, contains a roller, f, for each web of paper to be passed through it, the said rollers having their journals entered in slidingboxes 9, held in suitable guideways h, and made adjustable vertically in the trough by means of pinions i on the hand-shaft j, the said pinions engaging the teeth hat the upper ends of the boxes, as shown in Fig. 2 Each web for the body of the board is passed under its roller f and submerged in the paste, after which the webs so pasted are brought in contact and passed between the rollers d d, havin g preferably a felt or other usual jacket or covering. These rollers act upon the paper entered between them, whether it be one or more webs, to regulate or control the amount of paste left in the web or webs, this being determined according to the adjustment of the said rolls by the set-screws m acting on the boxes of the rolls, and where two or more webs are used and pasted the said rolls, by their pressure, unite them firmly together. The web so formed 1 shall hereinafter denominate the bod y-web, and it issues from between the rollers Z Z, pasted upon both sides, to be surfaced or covered by paper of same or better quality, or with cloth.

The surfacing or finishingwebs n 0, of cloth or paper, as may be desired, proceed from rolls 1) pabout and between therollers ll, as shown in the drawings, and thence back to a receiving-roller, 8, upon which the finished board is wound.

The shaft of the receiving-roller shaft has a pulley driven by a suitable belt, t from a pulley on the shaft o The pasted body-web is entered between the finishing-webs n 0, extended or turned each one about one of the rollers l l, and by the pressure of the said rollers upon the different webs between them (said pressure being controlled by the set-screws t) ,all are united in one solid web.

The boxes g are lifted to elevate the rollers and webs from the paste should the machine be stopped for a length of time sufficiently to soak the webs of paper with past'e, so that they would be liable to break under the strain applied to them by the rollers d 11. Each pair are to constitute the body of the card or colof rollers 01 d,l 1 has upon it a suitable gear, such as shown, a a and the gears of the lower rollers of each of the said pairs of rollers are engaged and driven by a larger gear. a, on the main driven shaft, (1", provided with a belt-pulley, a

I claim- In a machine for the manufacture of card or collar board. the rollers 11 d, and the pastecontaining trough and roller therein, to immerse in the paste the \vebof paper drawn through the trough by the said rollers 11d, the web being thus pasted on both sides, combined with rollers l l, to receive between them the body-Web pasted on both sides, and also the two surfacing-webs, to be delivered upon the opposite pasted faces of the body-web and be r 5 united with the body-web to form a single cardboard or collar-web, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two sub- 20 scribing witnesses.

CHARLES M. GAGE.
