13 Claims.

perienced in keeping the face of the blanket roller in good condition, the glue, varnish or other material used being quick drying 'so that when the machine stands idle the adhesive dries up and owing to the difficulty in removing this dried material there is sometimes long delay before the machine can again be operated.

It is one of the objects of the present invention to provide a construction wherein the disadvan-4 tages above referred to are eliminated by the' provision of a blanket roller, for applying adhesive to the strips, which can be'moved away from the roller which applies the adhesive to the blanket roller when the machine ls not in use, and when so positioned a brush or other roller carrying a solvent for the adhesive is brought into contact with the blanket roller thereby to dissolve the adhesiveV material thereon and place the same in condition for the next cycle of operation.

Other objects of my present invention will be manifest from the following description and the accompanying drawings, in which drawings:

Fig.' 1 is a sectional gelevation of my improved 30 device; and

. Fig. 2 is a plan view of the same.

Referring to the drawings in detail, I 'designate a frame or support for the device, the upper end of which is provided'with a pulley 2 mounted on 35 shaft 3 and driven from a suitable source of power C(not shown) through belt 4l Y The shaft'3 carries a pinion 5 meshing with pinion 6 mounted on shaft 1 on the machine frame'. This pinion 6 engages a gear 8 mounted -40 on shaft 9, the shaft y9 also carrying a feed roller III. I l

The gear 8 meshes with a gear II mounted on shaft I2, this shaft also carrying blanket roller I5. The shaft I2 is supported in the forked 4 5 ends of arms I3 pivotally mounted on stub shafts I6 in the frame ofthe machine so that the blanket roller I5 may be moved away from therotating in an adhesive solvent contained in a solvent tank 28. It will be obvious that when the hand lever 23 is manipulated the arms 24 will be raised and lowered thereby raising and lowering the brush 26 into and out of contact with the blanket roller I5. In this movement of the brush it will be appreciated that the gear will move about the axis of shaft I8 or, in other words, will roll around the pinion I9 so that the drive is not interrupted. The shaft 2| and consequently the brush 26 is driven through gear 25 meshing with pinion- I9. f`

The blanket roller I5 carries a removable blanket one end of which is secured to the roller by means of a clamp 36 pivoted at 31 and latched in clamping position by the latch 38. The other end of the blanket is wound about a rod or roller 39, and tightened by means of nut 4I|, reverse rotation of which is prevented by pawl 4| and ratchet 42.

The shaft 3 heretofore referred to also carries a sprocket 29 which receives a chain 30 for driving the adhesive applying roller 3|. This roller receives adhesive, such as glue or varnish, from roller 32 which is immersed in a tank 33 of the adhesive, and applies the same to the blanket of the roller I5 when strips are being fed through the machine, the blanket in turn transferring the adhesive to the strip of material in a. well known manner. The adhesive-applying roller 3| and the tank 33 are provided with the usual adjusting nuts 34 and 35, respectively.

It will be appreciated that the brush 26 is to be rotated only whenv it is-desired to clean the blanket of the blanket roller and `when no strips are being fed to the machine. To provide for such operation a clutch 43, carried on the shaft 2|, is

adapted to be manipulated through lever 44, pivto a transverse lever 46. This lever 46 is provided f at its outer end with a handler 41 and notches 48 adapted to lock the clutch in and out of clutching position, as will be obvious.

The free ends' of .the arms I3`which support the blanket roller I5 and gear IIare ladapted to be engaged by cam 49 xed to shaft 50, this shaft being rocked through the medium' of a double foot pedal 5|. It will be obvious that as this pedal is rocked the blanket roller I5 and the gear/II will be raised and lowered slightly. The teeth on the gears 8 and I I are out slightly deeper than usual to permit of this movement of the gear without the gear becoming entirely disengaged from the gear 8. It will be appreciated that in raising and lowering the blanket roller I5 the same follows an arcuate path about the fulcrum I5 so that the blanket roller I5 will be moved into and out of contactwith the adhesive-applying roller 3|.

Although the operation of my improved device will be readily understood from the foregoing description of the apparatus, I will nevertheless for the purpose of clarity here briefly describe the same.

As the strips are fed to the machine from the table 52 the same will be received between the feedroller I0 and blanket roller I5, the forward end of the strip being engaged `by grippers 53 on the feed roller in the usual manner. As the strip passes between the rollers III-and I5Lit receives adhesive from the blanket of roller I5,"the adhesive having rst been transferred to 'the roller I5 from the tank 33 by the adhesive-applying roller 3|. The strips are then discharged upon a conveyor belt 54 for delivery from the machine in the usual manner.

After the desired number of strips have passed through the machine the operator steps on the foot pedal 5I to rock the same clockwise thereby permitting the shaft I 2 carrying the blanket roller to be lowered to disengage the blanket roller from the adhesive-applying roller. Atthe same time the operator manipulates the hand lever 23 to raise the brush roller 26 into engagement with the blanket. The operator then throws in the clutch 43 to drive the brush roller,

. the periphery of which when it engages the roller I 5 traveling in the opposite direction to the roller I5, thereby applying a solvent to the blanket to dissolve and remove the adhesive therefrom.

It will be understood that my device has manifold uses such as, for example, in spot varnishing and other adhesive applying machines. It is also to be understood that various changes and modifications may be made in the device herein illustrated and described without departing from the spirit and scope of my invention.
