Serial No. 635,451.

A further object of the invention is to provide an automatic gluing and driving mechanism in which the glue pot is constructed to remove the surplus glue from the gluing fingers.

VVith the above, and other objects in view, the invention consists of the improved automatic gluing and driving machine and its parts and combinations as set forth in the claims. and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views Figure 1 is a side View of the complete gluing and driving machine; Fig. 2 is a side view on a larger scale of one-half of the gluing and driving machine, parts broken away to show interior construction; Fig. 3 is a transverse sectional view of the gluing and driving machine taken on line 3-3 of Fig. 1 parts broken away to show other parts in the rear thereof: Fig. 4. is a horizontal sectional view of the portion of the machineshown in Figs. 2 and 3 and taken on line 4t-4l of Fig. 2; Fig. 5 is a vertical sectional detail view of the dowel pin holder; Fig. 6 is a longitudina. sectional detail view thereof taken on line 6-6 of Fig. 5; l 7 is a side view of an ordinary door rail; and, Fig. 8 is a similar view with dowel pins inserted in holes provided in the end edges of the rail.

Referring to the drawing the numeral 10 indicates the base of the machine and 11 and 12 the gluing and driving machines mounted thereon. These machines are similar to each other with the exception that one is a stationary right handed machine and the other is a slida'ble left handed machine or reverse construction with parts in horizontal alinement with similar parts of the right handed machine to provide for gluing and driving dowel pins into the opposite ends of the rail. The right handed machine 11 is rigidly fixed on the base whereas the left hand ed machine is adjustably and slidably mounted on the base to provide for gluing and driving dowel pins into rails of different lengths. The left handed machine is ad justed toward or away from the right handed machine by means of a power driven screw 13 which is threaded into the frame 14 of the machine 12 and extends through the frame 15 of the machine 11 for connection with a source of motion. A drive shaft 16 extending in a line parallel to the base and through both frames serves to drive both the stationary and the slidable portions of the machine and in order to permit the slidable portion to be adjusted longitudinally with relation to the shaft the said shaft is provided with a longitudinal groove 17 and the connected motion transmitting parts are slidably keyed thereto.

As both half portions of the machine are similar in construction and operation only one half portion will be explained in detail but it is to be understood that the complete machine is contemplated in the specification.

The frame 11 supports and carries the rail hopper 18, the gluing mechanism 19, the reciprocal rail carriage 20 and the dowel pin hopper and feeding mechanism 21 which are positioned and arranged to perform their respective functions consecutively in the order named.

The rail hopper is formed of an upright end plate 22 rigidly connected to the frame and provided with upright side members 23 which are horizontally adjustably connected to the end plate by the slotted angular arms 24. The arms 24: are positioned in the horizontal grooves 25 of the end plate and extend outwardly therefrom and forwardly and toward each other and carry the upright side members 23 spaced from the end member and apart and parallel with relation to each other. Bolts 26 extending through the slots 27 of the arms and threaded into the end plate permit the upright side members to be spaced apart a greater or less distance to accommodate door rails 28 of different widths. The upper end 29 of the end plate inclines rearwardly and the upper end 30 of the outer side member is curved outwardly to provide for easily filling the hopper with the door rails 28. The end portions of the door rails are adapted to rest against the end plates of opposite portions of the machine and between the side members thereof and to be fed by gravity to the rail carriers positioned below the plane of said rail hoppers. The lower portion of the end plate 22 on a line registering with the end of the lowermost door rail within the hopper, is provided with a plurality of elongated slots 31 through which the gluing fingers 32 extend as they enter the dowel pin opening 33 formed in the opposite ends of the door rails. These fingers are carried by a frame 34 which is tiltably mounted on the cam actuated slidable frame 35. The slidable frame is recipro-cated in the ways 35 by means of a double faced cam 36 mounted on the main shaft 16. An antifriction roller 37 carried by the slidable frame 35 depends from thelower portion of said frame and is positioned between the two faces 38 and 39 of the double faced cam and is reciprocated thereby back and forth during each revolution of the cam.

The tiltable frame 34 is rigidly connected to and carried by a rock shaft 10 which is j ournaled in the slidable frame 35 and to the inner end of this shaft is connected a lever arm 41 having an antifriction roller 42 pro jecting from the side thereof. This roller extends beneath and engages the cam edge 43 of the cam plate 44: so that when the slidable frame is moved forwardly the lever arm will be forced downwardly and the glue fingers carried by the shaft will be swung upwardly to a horizontal position. The glue fingers in moving forwardly in horizontal position will extend through the elongated slots of the back plate 22 and enter the dowel pin holes of the door rail in register with said slots. The upper portion of each glue finger is provided with longitudinal grooves 45 to provide for holding a sufficient amount of glue to properly coat the interior walls of the dowel pin openings.

A glue pot 4:6 is located beneath the glue fingers and when the slidable frame in its rearlnost position the glue fingers will be inclined downwardly and extended into the glue within the pot by means of the coiled spring a? which is connected to the tiltable frame 34 and to an upstanding pin 48 pro jecting from the frame 11. The glue pot of rectangular formation and has a double bottom portion to provide a heating space 49 to keep the glue in a liquid state. Steam or hot water may circulate through this space to keep said glue warm.

A scraper 50 extending upwardly from the glue pot is provided to scrape surplus glue from the lower edges of the glue fingers back into the glue pot.

Tracks 51 and 52 extending transversely across the front portion of the frame and adjustably supported on guide ways 51 serve as ways to guide toe carriage 53 therebetween and the upper track also serves as a support for the door rails 28 which rest and slide thereon. Adjusting screws 52 provide for raising or lowering said tracks.

The carriage 53 is formed in two parts and 55 adjustably connected together by means of a bolt 56 having right and left handed threads and a medial head for turning the screw to adjust the two parts toward or away from each other. The carriage is reciprocated back and forth by means of a cam wheel 58 mounted on the drive shaft 16. This wheel is provided 'ith a cam groove 59 and an anti-friction roller 60 which is carried by a cam lever 31 extends intothe cam groove and is oscillated by the cam faces of said wheel. The cam lever 61 is in the form of a bell crank and is journaled medially on the stud pin 02 and at its upper end is pivotally connected to the carriage 20 by means of the link In order to adjustthe position of the rail carriage 20 with relation to its position on the tracks 51 an adjustable connection is provided between the link 63 and the said carriage. This connection comprises a slotted bar 6% to which the link is pivoted and a bolt 65 extending through the slot and threaded into the carriage. An adjusting screw 66 extending through the end portion of the slotted bar and threaded into the carriage provides for accurate adjustment of the bar when the bolt 65 is loosened. An adjustable dog bar 67 is also carried by the part 54 of the carriage and to the front end of this dog bar is pivotally connected a gravity rail dog 68 having its engaging end positioned to engage the side edge of the lower most door rail which is resting on the upper track 52.

The lower end of the side bar 23, to the left in Fig. 8, is spaced a sufficient distance from the upper edge of the upper bar as indicated by the numeral 69 to permit one door rail to be moved from beneath the other rails in the rail hopper. A stop pin 70 limits the movement of the rail dog.

The pawls of the carriages in reciprocating back and forth will pass beneath the lowermost rail during the rear movements of said carriages and will engage the rear ec ge of said rail at the end of said movement and when moved forwardly will slide the rail from the rail hopper to a position in register with the dowel pin hopper.

The portion 55 of the carriage is provided with a gravity discharging dog 71 which is positioned to engage the rear edge of the door rail in register with the dowel pin hopper and slide it beyond the pin hopper for final disposition. A stop pin 72 serves to hold this dog in rail engaging position.

In order to properly position a door rail so that its dowel pin openings will be in register with the discharge openings of the dowel pin hopper a movable stop member 73 is provided which is adapted to be moved upwardly to a rail engaging position when a rail is moved forwardly by the carriage dog 68 and to be moved downwardly to a disengaging position when the rail is engaged by the gravity discharging dog 71. The movable stop member 73 comprises a block 74 vertically slidably positioned in the guide ways 75 and provided with a projecting ant-ifriction roller 76 which is engaged by the cam edges 77 of the slot 7 8 of the forward portion 55 of the carriage. When the carriage moves rearwardly the cam edges will force the movable stop downwardly to an inoperative position before the carriage passes out of engagement with the roller so that upon the return movement of the carriage the door rail which was in register with the dowel pin hopper may slide on the rail above the movable stop. As soon as the rear edge of this rail has passed over said stop the cam edges of the slot will be in position to engage the movable stop roller and raise said stop to its upper position and in the path of movement of the rail which has been moved forward by the dog of the rearward portion 54: of the carriage. While the carriage is moving rearwardly the dog 71 will be forced downwardly by the door rail then in register with the dowel pin hopper. A stop pin 72 serves to limit the upward movement of the dog.

The dowel pin hopper 21 is of rectangular formation and the side portions 80 thereof converge toward each other toward their lower ends to direct the dowel pins 81 between the upstanding partition 82 which form pin separating compartments 83 leading to the discharge openings 8t through which the pins are pushed and into the dowel pin opening 33 of the door rails. The outer upstanding partitions are in two parts and the upper parts 85 thereof are mounted on rods 86 which extend loosely through the fixed portions of the outer partitions and are connected to a cross member 87. This cross member rests on top of the free end of a lever 88 which in turn rides on the vibrating wheel 89 mounted on the drive shaft 16. The free end of the lever is provided with a roller 90 which rides on the vibrating wheel. to eliminate wear and friction and the other end of this lever is pivotally connected to the frame by the pivotpin 91. The vibrating wheel is provided with a number of bumps or projections 92 irregularly spaced around the periphery of the wheel, to vibrate the upper parts of the outer partitions and cause the pins to settle into the pin compartments S3. The pins are pushed out of the compartments by means of plunger rods 93 which are connected to the slidable frame 35 and extend. through openings 9% in the rear wall of the pin hopper to engage the lowermost pin in each compartment.

In order to prevent short dowel pins or pins extending at an angle within the hopper from jamming or blocking and breaking the hopper when moved by the plunger rods the front portion 95 of the hopper is yieldingly connected to the hopper by means of arms 96 and springs 97. The arms are connected to the sides of the hopper by bolts 98 which extend through slots 99 in the said arms and the rear ends of said arms extend at right angles in the rear of the hopper and have the coiled springs 97 interposed be tween said hopper and the angular arni ends. Pins 100 projecting from the hopper end and extending through openings in the angular ends of said arms serve as guides for said arms and springs. The forward ends of the arms extend upwardly to form hooks or shoulders 101 which are engaged by latches 1.02 pivoted to the front portion of the hopper. By means of the yielding arms with hook ends and the latch construction the front portion of the hopper will give under strain and prevent breaking of the parts.

In order to securely hold the door rails in position while the dowel pins are being driven therein a yielding pressure plate 103 carried by the hopper front is provided which is positioned to bear on the upper surface of the rail above the upper track and between which plate and track the door rail slides. An adjusting plate 104 having an apertured horizontal projection 105 is located between guides 106 and is held in adjusted position by a hand screw 10'? which extends loosely through an arm 107 and is threaded into a portion of the adjusting plate 104. The adjusting plate is fastened in adjusted position by a bolt 10% which extends through a vertically extending slot 109 of the plate and is threaded into the hopper front 95. The pressurc plate 103 is provided with upstanding threaded rods 110 which ex tend loosely through the apertures of the projection 105 and have nuts threaded on their ends and springs 111 surrounding the rods and interposed between the pressure plate and the projection serve to yieldingly hold the pressure plate in position.

The anti-friction roller 87 is journaled on a stud shaft 112 which extends through a slot 113 of the slidable frame 55 to provide for adjusting the said frame with relation to said roller.

The shaft 13 is driven by means of a clutch and geared connection 11 1 with the shaft 17 when it is desired to adjust the dis tance apart of the two portions of the machine.

In operation door rails which are provided with the necessary dowel pin openings are placed between the end plates of oppo site rail hoppers with the lower rail resting on the upper tracks. The glue pots are provided with glue and the dowel pin hoppers with dowel pins and the machine is ready to be operated. Tn starting the machine the glue fingers which extend into the glue of their respective glue pots are swung to horizontal positions and advanced toward the dowel pin holes of the opposite ends of the lowermost door rail by means of the cams and the slidable frames moved thereby. The glue fingers in advancing toward the door rail will engage the scrapers of the respective glue pots and the surplus glue on the lower sides of the fingers will be scraped off the fingers and back into the glue pots. The fingers will be advanced into the dowel pin openings and carry sufiicient glue therein to coat the inner walls of the openings. The fingers will be immediately withdrawn from the opening and tilted down into the glue pots. As soon as the glue fingers are with- I rail carriages will advance the lowermost rail which has just been provided with glue to a position between the opposite dowel pin hoppers and beneath'the pressure plates of said hoppers. The rail will be stopped in proper position by means of the movable stop members and when this position is reachedthe two part rail carriages will start to return and to engage another rail. Simultaneously wit the movement of the carriages the dowel pins will be forced into the glue coated openings of the rails by means of the slidable frames and the plunger rods carried thereby. While this movement is taking place the upper portions of tie dowel pin hopper portions will be vibrated to cause the dowel pins to settle between the partitions so that when the plunger rods are withdrawn from their forward position other dowel pins will drop in position to be engaged by said plunger rods. The carriages in returning to their rearmost positions will cause the gravity dogs to swing beneath the rail which has just been provided with dowel pins and the gravity rail dogs to swing beneath the lowermost rail in the rail hoppers. When the carriages have reached their rearmost positions the dogs will have passed out of engagement with the rails and in positions to advance said rails during their next succeeding stroke. The carriages in returning to their rearniost positions will also engage and move downwardly the stop members so that during the next forward movement of the carriages the rail which has been provided with pins will be moved by the gravity dogs to a position on the end of the tracks for removal therefrom.

From the foregoing description it will be seen that the gluing and driving machine is automatic in its operations and will glue and drive dowel pins into both ends of a rail simultaneously. It will also be seen that the machine is strong and durable and is well adapted for the purpose desired.
