; ing veneer strips edge-to-edge, and retaining the strips in position until the glue has hardened sufiiciently to securely retain the strips against detachment.

At the present time, the usual practice for gluing veneer edges is to position the veneered strips in intimate contact, and then connect the strips with a piece of paper, and after the strips are connected, the paper acts a as a hinge whereby strips may be folded to permit glue or other similar adhesive being inserted between the edges and after the strips are again moved to a parallel plane so that the glued edges will be disposed in intimate contact, the strips are a usually r placed in a pressing machine to hold them together until the glue is set. The above operation takes considerable time and requires considerable labor, and it is, therefore, another object of my invention to provide a machine wherein the glue is applied directly to the edges of the'veneerstrips, and the strips then placed in my improved machine where the edges are moved tightly together, and all of the material adjacent 39 the edges is retained in a flat position until after the glue is hardened, thus saving the trouble of having to temporarily secure the opposed edges together and then glue them, which will mean a saving in time and labor for greatly reducing the cost of veneer gluing.

One of the great difficulties in gluing veneer strips ed ge-to-edge is the forcing of the strips tightly together and securely holding them until the glue has been properly set before releasing them, and it is another object of the invention to provide a machine with compressing members whlch engage opposed faces of the strips to be glued together and urges them into contacting relation with the adhesive between the strips and then securely holding these strips until the glue has set or hardened sufficiently so that it will not pull apart,

a 'A; further object of the invention is the Serial No. 453,269.

provision of a veneer gluing machine com prising opposed members having yieldably gripping and pressing members adapted to engage the veneer strips, and not only urge them together, but securely hold them in at- 5T tached position until the glue has properly set and includes means for quickly drying the glue while the strips are being held in intimate contact.

lVith the aboveand other objects in View, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and shown in the accompanying drawings wherein Figure 1 is a transverse section through the machine illustrating the gripping and pressing members in inoperative position about to engage opposed strips;

Figure 2 is a view similar to Figure 1 with the gripping and pressing members in engagement with the veneer strips, and illustrating them in operative position; and,

Figure 3 is a front elevation of the machine with parts thereof broken away and illustrated in cross section.

Referring more particularly to the drawings, it will be noted that I have illustrated the construction in one of its embodiments,

audit will be apparent that the machine may be made in various sizes for gluing narrower strips or comparatively wide panels, and in the present instance, suitable spaced standards 1 are provided which pass upwardly through the movable blocks 2 and 2'. The blocks are reinforced at their ends, as shown at 3, and each reinforced portion is provided with a recess 4 arranged in opposed relation. as shown in Figure 3, and mounted upon the standards 1, with their ends extending into the recess 4 are the coil springs 5, which normally urge the blocks 2 and 2 apart.

Extending longitudinally of the movable blocks2 and 2 are the shafts 6 having mounted thereon cams 7 adapted to engage lateral projections 8 on the reinforced ends of the blocks for urging the blocks toward each other as the high points 9 of the cams contact with the projections 8.

an inclined wall 12. Theouterend of the bores 10 are provided with restricted openings, and movable theretlncuglr are the plungers 13 which are provided with enlarged cylindrical portions l l adjacent their inner ends which-are of a diameter equal to the diameterof the bores, so as to fit snugly therein.

At the inner ends of the plungers and integralwith the enlarged cylindrical portions 14L are the presser feet 15 having comparatively rough faces, as illustrated in Figures 1 and 2.. Thesepresser feet are provided at one sidewith an inclined wall16 adapted to cooperate with the inclined wall 12. ofthe recesses 11.- i The outer end ofthe plungers 13 are provided withv stop heads-17 for limit ingzthe, inward movementofl the plungers. Normally, these pl-ungersare moved inwardly by means of the coil springs 18 whichsurround the plungers within the bores 10' and aredisposed between the enlarged portions 14 andthe inner ends of the bores;

eirranged-centrally of each, of the blocks 2' and 2 is a heating element 1'9 which is disposed betweenthe opposedsets of presser feet, as shown in Figures land 2,

In the operationof this machine, it; will be apparent that .when'it is desired to glue the edges of opposed strips or panels, the two pieces of material which are to be glued together have glue or other suitable adhesive applied to the edges thereof and the two pieces are then inserted: in the machine, as shown. in Figurel, until, the edges are comparatively close together. At this time, rotative movement is, imparted to the shafts 6 until the high points 9 of thecams 7' engage With the lateral projections 8' on the block, at which time the blocks 2 and 2 will be urged toward each other, bringing the presser feet 15 into contact with opposed faces of the, two pieces to be gluedtogether. As the blocks move together, the presser feet will be urged intothe recesses 11, and due to the inclined walls of the presser feet, and the recesses, the opposed presser feet will have a tendency to move toward, each other, thus drawing the two pieces of material toward each other, and causingthem. to be brought int intimate contact, as shown in Figure 2, it being understoodthat the. coil springs 18 are placed under tension, as illustrated;

When the twopieces of imatenial-i are moved tightly togetherfas shown Eignre, 2, and the presser feet 15 are in their innermost position within the recesses 11, the edges of the two pieces of material will be brought tightly together, and the blocks 2 and 2 are retained in this position, shown in Figure 2, until the glue or adhesive has had time to properly set, and in order to hasten the setting of the adhesive, the heaters 19 are used" and; these heaters are preferably-in suchposition that they are arranged upon opposite sides of the glued joint. 7

It will be noted that when the high points on the cams are moved from the lateral projections 8, the presser feet 15 have a tendency to exert an outward pressure on the two pieces of material, therefore, it is essentialthat the glue or adhesive be properly set before the blocks are released in orderfto prevent the two pieces of material from being pulled apart due tothe action of the presser feet'15, when the blocks are released,

It will be apparent from the foregoing that with the use of such a machine, the opposed edges of strips, panels, and similar veneer-like pieces, can be quickly and easily glued together edge-to-edge and the glue be properly set before the pieces; are released.

The machine can be made of sufiici-ent size toaccommodate various sizes ofveneer pieces and with. the use of the machine, these veneer pieces can be very quickly glued together, and due tothe heaters 19, the glue --will be properly: set before the pieces are released.

\Vhile I have shown anddescribed the preferred embodiment of my invention, it will be apparent that slight changes may be made in the construction when puttingthe invention into practice without departing from the spirit of the same or the scope of the appended claims.
