Application filed March 11, 1913. Serial No. 753,474.

To all whom it may concern Be it known that I, JOHN N. LILYGREN, a citizen of the United States, and resident of West Allis, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Pressing and Gluing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to provide a simple, effective and durable machine for assembling and glue-jointing members, the invention being particularly designed for assembling and gluing the stiles to the body portions of doors, the joints between said members being effected by dowel and socket connections.

With the above objects in view the invention consists in certain peculiarities of con struction and combination of parts as set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a plan view of a machine embodying the features of my invention with parts broken away and parts in section to more clearly illustrate structural features; Fig. 2, a crosssection of the same, the section being indicated by line 2-2 of Fig. 1; Fig. 3, a longitudinal elevation of said machine partly broken away and in section as indicated by line 33 of Fig. 1; Fig. 4, an enlarged detailed sectional elevation of a glue-distributer mechanism such as is employed in the machine, and Fig. 5, a fragmentary longitudinal view of the same, showing the dowel-pins in sect-ion.

Referring by characters to the drawings, 1, 1, represent corner posts of a frame and 2, 2, sets of intermediate posts, the companion corner posts and intermediate posts of each set being connected by transverse struts 3, 3, and the corner posts of opposite sets are also similarly connected by longitudinal struts 3, 3, the assemblage of parts together forming a rigid skeleton frame. As best shown in Fig. 2, the companion corner sets of posts carry brackets 4, into each set of which brackets is journaled the ends of a transversely disposed screw-threaded spindle 5, the threaded sections of which spindle are arranged in right and left pairs. Each spindle also has a pair of center bearings in boxes that constitute parts of brackets 6, the same being mounted upon the upper ends of the intermediate posts. The pair of threaded spindles 5 carry corresponding sets of nuts 7, 7 7, 7 each of which sets of nuts are connected by longitudinal angleiron supports 8, 8, which supports constitute rests for stiles A, A, that form members of a door to be assembled. These stiles are adjusted against stop pins 9 with which the angle-iron supports 8, 8 are provided, the said stiles, as best shown in Fig. 1, being also provided with three groups of dowel apertures 10. The brackets 6 are longitudinally connected by parallel door-supporting rods 11, upon which rods the body 13 of the door is adapted to rest, the same being constructed in any suitable manner, the door shown in this instance being formed by top, bottom and. intermediate cross-rails, together with suitable panels. The cross-rails of the door body have projecting from their ends, groups of dowel-pins 10, which dowelpins are adapted to enter the dowel-apertures 10 of the side rails.

As best shown in Fig. 1, one end rail of the door body is abutted against a stop-web 12, which stop-web is adjustably connected to the supporting rods 11, whereby the door may be accurately positioned so that its dowel-pins will aline with the dowel-receiving apertures of the stiles. The door body is longitudinally chucked against the stop web 12 by a block 13, which block is in slidable union with the door-supporting rods 11 and is adjusted by means of a cranked screw-threaded rod 14, the same being journaled in a fixed web 12 which connects the adjacent brackets 6 and said cranked rod is held against end play to its bearing by suitable collars.

The door body A is transversely chucked between longitudinally disposed rocker- bars 15, 15, which rocker-bars carry wing-strips 16 that are adapted to impinge against the adjacent edge of the door-body in a clamping or chucking operation. These rockerbars are each ournaled in companion brackets 17, 17, and 17, 17, respectively. The ends of the rocker-bars carry weighted arms 18, whereby the wing strips 16 are held in abutting engagement with the door edges, the movement of the rocker-bars in this direction being limited by stop-pins 18 that engage the arms. A pair of the weighted or yielding arms 18 are provided with curved tail-pieces 19 which tail-pieces constitute automatic door-releasing means for the wings 16, the said tail-pieces being so disposed as to be engaged by the stile-supporting rests 8, 8, when the latter are moved inwardly, whereby the wings 16 will be automatically rocked clear of the lower faces of the door body prior to the stiles being forced into abutting engagement with the edges of said door body. The spindles 5 are driven from a longitudinally disposed power-shaft 20, which power-shaft is in worm-gear connection therewith, the power being applied from any suitable source to said shaft, through a belt that is arranged to be shifted from a tight to a loose pulley, with which the shaft is provided.

Secured to the pairs of brackets 17, 17, respectively, are longitudinally disposed glue reservoirs 21, which reservoirs, as shown, are each partly submerged in a tank 22 that is rigidly connected to the frame by means of suitable cross-braces 23. The tanks, as shown, normally contain water which is heated by means of steam pipes 23, the said water serving to maintain the glue within the reservoir at the desired temperature. Mounted in the brackets 17, 17, are rock-shafts 24: the same being extended through the end-walls of the glue reservoirs. Each rock-shaft 24: carries a pair of arms 25, which arms are connected by parallel rods 26 that serve as supports for a gluedistributer. This gluedistributer comprises a skeleton frame 27 which is in the form of an open-mouthed box. The frame serves as a support for a lining 28 of porous material having extended from its side-walls upper and lower series of glue-retaining strips 29, which strips in this instance are shown split to form two series of tongues that overlap each other, the base of the strips being stiffened in any suitable manner to hold them in their proper relations.

It is understood that I may, without departing from the spirit of my invention, utilize any form of brush or distributer as a substitute for that mentioned. Each rockshaft 21 is provided at one end with a hand crank 24-, whereby the glue-distributers are oscillated, it being apparent that when the rock-shaft is moved in one direction that the distributers are immersed within the glue and when they are swung upward or in the other direction they will incase the various sets of dowel-pins carried by the door and the glue-ladden tongues will thus thoroughly distribute the glue upon the surface of said pins, this operation being effected by manual power applied to the independent cranks 24. In this connection however it is manifest that the hand cranks 24: may be connected by a suitable link, not shown, whereby the movement of the gluedistributing apparatus will be simultaneous.

The sets of brackets 17, 17, respectively, are mounted upon guide-rods 30, with which the frame is provided and the lower ends of these brackets are provided with threaded apertures constituting nuts for engagement with threaded spindles 31, each spindle being mounted within bearings that are carried by the posts, it being understood that the opposite threaded ends of each spindle are pitched right and left. These two spindles 31 are revolved by means of a shaft 32 which shaft is in worm-gear connection with the spindles and carries a hand-crank 32, whereby it is manipulated. Hence it will be understood that the pairs of brackets 17 and 17 and their various connections may be adjusted in or out with relation to each other to accommodate different widths of work, the gluing apparatus, owing to its connection with the brackets, being shifted there with, whereby the glue-reservoirs will travel back and forth within the heating tank. It is also manifest that owing to the length of the adjusting rod 14, the block 13 may be shifted so as to accommodate different lengths of work, whereby the machine is capable of meeting the various conditions with respect to ordinary mill-work of the general type to which the machine is applicable.

Having fully described the mechanism in detail it is obvious that after the various adjustments have been effected a door-body B is first placed in approximate position upon the supporting rods 11. Thereafter the threaded spindles 31 are manipulated through the driveshaft 32, which movement will cause the wings 16 of the rockerbars 15, 15, to impinge against the edges of the door body and chuck the same securely in a central position. After this side chucking operation the door is longitudinally chucked by manipulating the threaded rod 14, whereby its block 13 will engage one cross-rail and force the opposite cross-rail against the web-stop 12. The rock-shafts 24 which carry the glue-distributing apparatus are then manipulated, whereby said apparatus is lifted from an immersed position within the glue reservoir to a position where all of the dowel-pins are enveloped and thoroughly coated with glue, the said gluing apparatus being then returned to normal position within the tank. Presuming that a pair of stiles are seated in their respective angle-iron supports 8, 8, power is then applied to the shaft 20, whereby mo-, tion is imparted to the spindles 5 andthe said supports through their nut connections with the spindles are thus simultaneously drawn toward the edges of the door, their dowel apertures being forced upon the now glued dowel-pins. Just before a butt-joint is formed between the edges of the stiles and door-body, the rails 8, 8, due to their engagement with the cam-faced tails 19, will cause the rocker- bars 15, 15, to swing, whereby the wings 16 are automatically moved clear of the path of travel of the stiles. Thus the joint is effected and the parts rigidly pressed together to complete the door by the applied power. It is manitest that after the completed door is removed the brackets 17 and 17, are slightly spread apart for the reception of a second door body and that the stile supporting bars are shifted back, whereby the rocker-bars and their chucking wings will automatically assume their normal positions.

It is obvious that while I have shown and described the machine equipped for gluing and pressing two members to a body member, it may be utilized for operating upon a pair of members only and, furthermore, I may, without departing from the spirit of my invention, arrange one of the rocker-bars l5 and its stop, together with the gluing mechanism, in a fixed position and utilize a single adjustable pair of wormcontrolled brackets 17 for efiecting the side chucking movement.
