To LZZ whom t may concern: y
Be it known that I, GHARLEs E. FRANCIs', a citizen of the United States, and a resident of Cincinnati, Hamilton count-y, State of Ohio, have invented certain new and usefulV Improvernents in Glue-Spreaders; and I do declare that the following is a description thereof so clear, full, and exact as to enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying'drawings, with the reference-numerals marked thereon, which form also a part of this specification. Y j
This invention relates to machines used in wood working, and particularly to such whereby glue is applied to larger surfaces of wood when such latter is to be connected by gluing. The glue is usually applied by rolls partly immersed, dipping into, or being otherwise in contact with liquid glue contained in suitable receptacles, and from which latter the glue is taken up by the absorptive surfaces of the rolls and thereby transmitted to the wood while this latter passes through the machine.
The leading feature of my invention is a glue-spreader so constructed as to permit it to be used either to apply glue at the same time to the two opposite surfaces of a piece of wood, plank, board, doc., or only to one side thereof. 1
Another feature is the use of a press ure-roll coacting with a glue-spreader roll when glue is applied to one surface only at a time.
There are also features of construction in general and in detail, all of which will be more fully set forth hereinafter.
In the following specification and particularly pointed out in the claims at the end thereof is found a full description of my invention, together with its operation, parts, and construction, which latter is also illustrated in the accompanying drawings, in which- Figure 1 is an 'end View of the machine. Fig. 2 is a vertical section of the upper part ot' the machine, taken on a line back of Fig. 1. Fig. 3 is a View similar to Fig. 1, showing the opposite end of the machine. Fig. 4 is a vertical section of the upper part of it, taken on a plane back of Fig. 3. Fig. 5 is a front view of the machine. Fig. Gis a section on line 6 6 of Fig. 1.

supporting the upper roll.
Sis the lower and 9 t-he upper glue-spreader roll, consisting each of a suitable core, the outer surface of which is rendered sufficiently absorptive to enable it to take up glue and transfer it to the surface of the wood. In the present case this absorptive surface is obtained by covering the core with a material like cloth or carpet. The journals of the lower roll are mounted in boxes 11, while those of the upper one are carried in boxes 12. y 13 is the glue-tank for the lower roll, being surrounded by a customary jacket 14, the space between the two being filled with hot water or steam, which is kept in circulation and serves to maintain the glue in proper condition. The latter is supplied by a gutter 15 from a suitable glue-supply tank or boiler, (not shown,) while the steam circulates through pipes 16 and 17. The glue-tank may be emptied entirely through an outlet 18.
Figs. 1 and 2 show the machine used for applying glue at the same time to two oppopartly in section, of the means for ad justably site surfaces, for which purpose the upper.
roll is moved down toward the lower one and properly adj usted with reference to the thickness of the woodwhich is to pass between them. For purposes of such adjustment the boxes of the upper roll are connected each to a screw 19, upon each of which is also mounted a nut 21. These latter by means of collars 22 are prevented Vfrom moving longitudinally on screws 19, but are free to rotate about them, which rotation causes such screws to either rise or fall, carrying With them boxes 12 and the upper roll mounted therein. During such movementthese boxes are guided by the machine-frame to which they are fitted.
Nuts 2l are operatively connected to each other by means of bevel-gears 23 and a shaft 24, mounted in brackets 25, so that they may be simultaneously rotated. For the necessary manipulation a hand-wheel 26 is provided on The position of the rolls is not absolutely rigid, but permits a limited automatic adjustment of the space between them and through which the wood passes to accommodate any irregularities in the thickness of this latter,'as well as to have said Wood engaged by a live pressure for the purpose of moving it. All this is obtained by connecting the lower ends of the screws 19 loosely to boxes 12 and interposing springs 27 at the points of connection. The details of this construction are as follows:
The upper part of each box 12 is "recessed and part of each recess is closed by a collar 28, held in place bya set-screw 29. The lower ends of screws 19 are reduced in diameter and pass loosely through an opening in the collars, below which they are each provided with a shoulder 30 to prevent disengagement of the parts. `Some distance above there is another shoulder 31, and between it and the boxes` below said springs 27 are conined.
It will now be seen that for purposes of mere support and for positive movement during adjustment boxes 12 are rigidly connected to the lower ends of the adjustingscrews; but for the purpose of an automatic adjustment the upper roll is capable of yielding upwardly to an extent equal to the depth oij the space below shoulder 30. The'upper shoulder 3l is preferably in shape of a nut, being thus rendered movable in position and permitting adjustment of the pressure of the springs. By means of a key and groove or by shaping a portion of the screws otherwise than round these'latter are prevented from turning while nuts 21 are manipulated, which portion or key and groove ispreferably placed at the point where screws 19 pass through collarsl 28.
The upper glue-roll 9 is supplied from a trough 32, supported in front ot' it and lying across the face thereof, its side toward Vthis latter being removed and its place taken by opposite parts of the face of roll 9, against which latter the glue constantly lies, and is thus conveyed thereonto. The other side and the bottom of this trough are jacketed, as shown at 33, the space between being filled with hot water or steam circulating through pipes 34 and 35, whereby the glue is kept in proper consistency. This trough is preferably formed of a hollow casting, shaped as shown, and the ends of which are closed by heads 36. It is supported by two brackets, being fitted between dovetailed slides 38 thereon and on which it is adjustable to or from roll 9, being held in its adjusted position by set-screws 39, passing through slots in the brackets. By means of adj Listing-screws 34, mounted immovably, except as to rotation, at the ends of the trough and engaging stationary nuts 42 at the ends of brackets 37, this trough may be. moved to and from the face of roll 9 for the adjustment mentioned, thereby regulating the amount of glue supplied yto this latter, edge 43 of the trough acting as a scraper-for such purpose. Bracketsl 37, which carrythis glue-trough, are secured to or form part. of boxes 12, which support the upper glue-roll, so that this latter in all of its adj ustments carries its gluesupply constantly with it. A gutter 44 supplies this trough from the same source which supplies tank 13. Any excess in the former stance, by a .pulley 46.

The poweris supplied at one end of the lower glue-roll in any suitable way-as, for in- From here the power is transmitted to the upper glue-roll by means of sprocket-wheels 47, mounted at the other ends of each of the rolls and connected by a chain 48.
49 and 5l are idler guide pulleys, which support the chain in a manner to guide its movement in the proper direction.
If it is desired to use the machine for applying glue on one side only of the wood, then This latter pulley being adjustably supported on a,
the upper glue-roll and its trough are raised by means of screws 19, operated by hand-W wheel 26. the wood against the lower glue-roll is now supplied by a pressure-roll 53, hitherto'unused and occupying a position out O f the Way, as shown in Figs. 1 and 2. This roll is can ried between arms 54, pivoted on brackets 55,V
forming also projecting parts ef boxes 12, and is now swung down to a position as shown 1n The necessary Vpressure to hold Figs. 3, 4, 5, and 6, and in which position it is held by links 56, which are connected each with one of their ends to arms 54 and with their other ends to brackets 37. This latter connection is byhand-'screws 57, which per-v mits quick and convenient disconnection or reattachment to change the machine to one operating either with a double or with a single glue-roll.
