11 Claims.

This invention relates to adhesive applying mechanism and particularly to mechanism for applying glue to the cap or ferrule of a pencil.

It has been customary for many years to use -metal caps on pencils and to secure the caps to the pencils and the plugs or erasers in the caps by pricking the metal cap.

At the present time, due to the necessity of conserving metal, caps of paper, plastic or other non-metallic material are used. The cap is Ys,.- cured to the pencil and the plug is secured to the cap lby adhesive or glue.

This invention has for its salient object to provide simple, practical and eiective means for applying glue or adhesive to parts to be glued.

Further objects of the invention will appear from the following specication taken in connection with the drawings which form a part of this application, and in which Fig. 1 is a vertical sectional elevation through a device or mechanism constructed in accordance with the invention, this View being taken substantially on line I I of Fig. 4, looking in the direction of the arrows;

Fig. 6 is a sectional elevation taken substantially on line 6 6 of Fig. 5, looking in the direction of the arrows.

The invention briefly described consistsof vadhesive applying mechanism comprising a container for the adhesive, an apertured member movable through the adhesive, and reciprocatable means which is also preferably rotatable for discharging the adhesive from the apertures and transferring the adhesive to the parts to be glued.

Further details of the invention will appear from the following description.

In the particular embodiment of the invention illustrated in the drawings, the mechanism comprises a main frame member or casing I0 having a cover II at one side thereof and a cover I2 at the other side thereof, the latter cover including a cover plate I3.

The main casing I0 is carried by a bracket I5 and is adjustably mounted thereon in the following manner. An L `.shaped support or bracket I6 is adjustably secured to the end of the bracket I5 by a bolt I'I which extends through a slot I8 in one arm of the L shaped member I6. A stud I8 is threaded into the end of the bracket I5 and has a groove l2l)r which receives a ange or lug 2| formed on the upper end of the vertically extending arm oi the L shaped bracket I5. The bracket I6 is vertically adjusted by the rstud I9 and after it has -been adjusted thereby it is clamped in place by the stud Il. Suitableguideways are provided between the outer end of the arm of the bracket I5 and the vertical arm of the L shaped bracket I6.

The casing I0 has a plate 25 secured tothe upper surface thereof and the plate 25 has a longitudinal rib 26 which forms a horizontal guideway and extends into a correspondingly shaped groove 2l in the under surface of the horizontal portion 28 of the L shaped support or bracket I6. A stud 29 extends through the portion .28 which is slotted to receive the stud and is threaded into the plate 25.

The main casing IIJ is provided with lbearings 30 and 3l in which is rotatably and slidably mounted a spindle 32 having at one end thereof a portion 33 provided with a spiral groove 34. A collar or bushing 35 is secured to the outer end of the bearing 30 and is provided with a 'lug 36 which extends into the spiral groove 34. Thus, as the spindle 32 .is moved longitudinally Vin the bearings 30 and 3| in a manner hereinafter ldescribed, the spindle will be simultaneously rotated on its axis.

The spindle 32 has secured to one end thereof a plunger 40, a flange 4I being provided at the end of the spindle and at the inner end ,of the `plunger 40.

'Ihe spindle 32 is reciprocated by means of a yoke 45 having a bifurcated end 46 positioned in the groove of a collar 41 mounted on the spindle. The other end of the yoke 45 has an angular .eX- tension 48 which is secured to a plate 4.9 which is slidably mounted in guideways 50 formed in a plate 5I which is secured to one wall of the casing Ill. This wall is provided with .longitudinally extending

slots

52 and 53. The yoke 45 extends through the slot 52, as shown in Figs. -4 and 6. From the showing in Fig. 4 it will be ynoted that the guideways between the yplates 49 and 5I .are beveled, and that the plate 4,9 engages the outside of the wall 55 Aofthe Acasing Ill.

The plate 49 has secured thereto an outwardly extending stud which extends through a slot` 6l in the cover plate I3 and has connected thereto an arm or link 62 by means of which theV plate 49 is recprocated.

As the plate is reciprocated in the manner just described, the spindle 32 will also be reciprocated and dueto the. spiral groove 34 and lug 36 the spindle will also be simultaneously rotated.

During this motion the plunger 40 will be I formed in the plate 49. The outer end of the extension 13 has secured thereto a spindle 15 I which is rotatably mounted in lugs 16 carried by the outside of the plate 49. A spring 11 surrounds the spindle 15 and normally holds the arm 12 and tooth 1| in position to engage one of the teeth of the worm wheel 10 when the i tooth and arm are moved to the left, viewing Fig.

1. During the return movement of the plate 49 and the parts carried thereby, including the arm 12, the spring 11 permits the arm to raise so that the arm and tooth may return to their original position without causing the worm gear 10 and shaft 61 to rotate.

The disk 66 during its rotation passes through adhesive contained in `a receptacle or container 80 which is detachably supporting by interengaging flanges 8| and 82 and a latch 83 on the bottom of the casing I0. Adhesive is supplied to the receptacle 80 from an inverted container 84 which is supported in a sleeve or cylindrical casing` 85 having a downwardly extending portion 86 which is supported in an opening 81 in the casing I8.

In order to remove air from the apertures carriedl back into the receptacle I and to fill the apertures with adhesive, there is provided a thermore, the rotation and reciprocation of the plunger into the cap will force adhesive into the inner end of the cap which is mounted on the shouldered end 96 of the pencil P. After the plunger 40 has performed its operation it is withdrawn and the disk then rotates to bring another aperture into alinement with the next pencil and the foregoing operation is repeated. During the passage of the apertures through the adhesive into the receptacle 88, the plunger 88 operates in the manner hereinbefore described to remove air from the apertures and to supply adhesive thereto.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
