GLUING-MAGHINE Specification of'Letters Patent. Patented March-16, 1909.

Application filed Mag 2, 1908. Serial No. 430,592.

To all whom it may concern:

Be it known-that I, FREDERIC SUTTER, a

citizen of the United States, residing at Shelby, Ohio, have invented certain new and useful Improvements in Gluing-Machines, of which the following is a specification. p

My invention relates to an improved machine for gluing together the edges of boards or stri s 'to produce a large sheet composed of a pur'ality of such strips firmly secured to et er.

have'aimed among other things to procould be fed insuccessively at one end and passed slowly through the machine,ybeing eld in. alinement and with their edges pressed firmly together whilepl ssing through ing an embodiment of the'machine,Figure 1 'isa 'be supplied. in any suitable manner forkele e.

plan view with the central portion of the mac ne broken awa elevation ofthe mac "no, a so with the centralportion broken away. Fig. 3 is a front endview, and Fig. 4 is a'rearend'view, while 5 is a detail view.

Fi .ite ferring .by reference characters to these drawings, the numeral 10 designates a glue roll which rotates in a glue tank 11 supported upon suitable pedestals 12- and provided with. a steam jacket 13, to'which steam may ing t e Inc in a liquid condition. strl s to e glued together are shownat 14 an firsthave theiredges pressed upon the .to the feedrolls 16. 1 These are journaled at x the front end of a table or supporting struc-' ture. '17 and may convenient y .powe1 imparted thereto from the power I surface-of the glue roll to apply the glue to the edges and they are thereafter placed upon the'horizontal u per surface of an end-- less chain'carrier 15, y which they are fed by worm gearing 17"., which latter has Fi .-2 is asectional be operated 19-20, the motion being transmitted through suitable s eed reducing gearing in-. dicatedat 21. '1 e strips are. pressed by these feed rolls, which rotate very'slowl on to the horizontal rails '17 of the tab ev or supporting structure and areheld pressed down upon these rails so as to be maintained in alinement-by an endless moving presser device. I his comprises a plurality of end less chains 22 carrying transverse; presser bars 23, the chains traveling around idle shaft 18 carrying fast and loose pulleys wheels or drums 24 at the front andrear ends of the table respectively.-- As the .presser bars 23 ass around and under the ums, they pass beneath front rolls or yielding uides 25 which are s detail-in ig. 5.

own more in sist of a plurality of longitudinally disposed bars 26 arranged end to end andextending the entire length of the table. The ends of These guides "25 each con- I adjoining bars are connected by links 27; as

shown in detail in Fig. 5, and to these links I l are connected vertical rods 28 which have reduced upper ends seated in the "hollow or tubular screw members 29] whichfpass through the transverse supporting-bars 30.

The screw members 29 have flanges 31'at' their lower ends and the rods28 have similar 1 flanges 32, and between these flanges are located helical springs '33. These springs'tend' to constantly press the longitudinal bars .26 downwardly, these latter m -turn pressing the strips to be glued firmly 'downupon-the The tension on the springs, as.

rails 17*. y will readily be seen; may bead usted; by simply turning the screws 29 1n a proper dv rection It will thus be seen that the endless chains with the presser-bars 23 move with the strips to be glued, holding them pressed down upon the rails and in perfect alinement' andas therails afiord consider ableresistance'to the passageof the bars,

the strips as fast as the rare fed in will'be pressed tightly against t e edges of the pre-I ceding strlps as the latter areforced forward solely and entirely by the action'of the feed rolls '1 6 upon succeeding strips. The length of the mac strips have reached the rear end of the-niaissue as acontinuous-sheet 'orfilm.

It will be, understood'that the mac of such a length as to require a considerable number of members 26' laced end to end and connected as'abovet escribd warm a inc is such that by the't'nne the} ice - chine the glue has become set and the strips r 6 IS- continuous guide, and, owing to the length of the machine, it has been necessary, in Figs. 1 and 2 showing the plan and sideelevation, to break away the central portion and show only the two end portions drawn together, so 1; at onlythe outer ends of the lengths of guide bars show in these 'two views, the intermediate portion being illustrated in detail in Fig. 5. In order to hold the presser guides 25 against longitudinal movement, I provide links 34 extending": between thetransverse s'irable to 4 machin bars'85 and the guide bars. I have found that sometimes with strips of certain kinds of wood it is desirable to provide greater resistance to the through the machine than is afiorded by the guide rails 17. To accomplish this I. provide a friction drum 36 upon the shaft of the front rolls. or drums 24, encircling this by a suitable machine brake by which additional resistance may be afforded to the movement of the parts. -I findalso that itm'ay be deprovide either corrugations or proections on the contact faces of the resser are 23 so as to prevent slipping 0 these upon the strips which pass through the As thestrips issue from the endofthe machine as a continuous'composite or compound board, I find it desirable to provide means for severing this into sections of the desired size without interrupting the motion of the machine. Toacc'omplish this, I provide 'a transverse cutter in the shape of a cit cular saw 37 driven by suitable flexible operating-c'omi'ections 38 from a motor 39, the

' ried by a frame 42 and is arranged to move saw being mounted on a carriage 40 moving in a transverse guide way 41, so as to cutat right angles to the-line of movement of the assembled stripsl This guide way-41' is carlongitudinally, for this purpose being mounted upon rolls 42" and operated so that during the transverse movement of the saw during the-cutting operation, it is moved forward in .the material unison with thetravel of the strip, while after it has 'passed through and clear of the strip it is carried toward the tail "end of the machine, an equal amount to-beread for a fresh cut. Means. are provided by which the movement of the saw'mgfi be timed and thus automatic y cut into any desired r1 scornpnsing'stationa lower horizontally disposed sup ry or rails, endless carriers mova supported 7 gabovesaid rails, transverse presser bars car- "ried by said endless carriers, and feed .rolls forforcing the strips to be'glued successively passage of the strips 14' I Having thus described my invention, what 1.
