Definitions

  • Cartridges of what is generically referred to as "caulking" are ubiquitous in our culture, particularly in the construction trade and in the home repair and restoration avocations.
  • the contained product is generally a thick plastic material which may be squeezed or expelled from the cartridge at one end through a tubular dispenser tip, by pushing in a piston on the opposite end.
  • caulking such cartridges are used to contain and dispense various glues, adhesives, settable or curable plastic resin compositions and the like, all in pure form or as compounded with usual binders, extenders, preservatives, thickening agents, solvents, plasticizers, colorants, masking agents, dispersants and the like.
  • cartridges are used as replaceable mates for the familiar receivers which have trigger-actuated ratchet-advanced plungers which abut the cartridges' pistons and push them forwards. These are referred to herein as cartridges or containers of the "push-in piston type”.

  • the body cavity 12 is shown provided with a second opening 70.
  • a reverser mechanism is shown at 72.
  • This may be of an off-the-shelf, presently commercially available item that is well known in the power drill art. Basically, it includes an input shaft 74, an output chuck 76 and an assembly of components 78 between its input and output ends, which may be manipu ⁇ lated, grasped, immobilized or turned, in order to switch between two modes of operation: a first mode in which the output chuck will rotate in the same angu ⁇ lar sense that the input shaft is rotated and a second mode in which the output chuck will rotate in the angularly opposite sense that the input sha ⁇ t is rotated.
  • These devices 72 are widely sold in order to permit users of inexpensive, non-reversing power drills to upgrade their equipment so as to have a reversing capability at a lower cost than replacing their power drill with one that incorporates a reversing mechanism. Because such devices are widely known and commercially available the inner working of the device 72 will not be further described herein even though such a device may be used that is specially constructed for the present device 10, rather than commercially purchased. Suffice it to say that the reverser device 72 is partially or substantially received in the cavity 64 with its output chuck 76 receiving and being secured to the shaft 68 of the second pinion gear 54, and with its input shaft 74 projecting axially rearwards out of the cavity 64 and body 12 through the opening 70.
  • the mechanism components 78 are accessible for intermodal manipulation by being partially externally exposed as at 80 and/or by being indirectly manipulable via a suitable actuator means 82 mounted on the outside of the body 12 and protruding into the cavity 64.
  • the input shaft of the reverser is posi ⁇ tioned to be removably received and mounted in the chuek T of the rotary power tool R for use.
  • the plunger and adapter mounting region 16 of the body 12 is shown comprising a generally tubular side wall 84 with a closed rear end wall 86 and an upwardly opening slot 88 running substantially the length of the side wall 84 in the upper portion thereof.
  • the front end wall -of the body region 16 is part of the rear end wall 90 of the receiver 24 and has an opening 92 axially therethrough.
  • a generally hori ⁇ zontal web 94 divides the interior space of the side wall 84 into two compartments, of which the upper one is laterally upwardly open via the slot 88 and includes the opening 92.
  • the web 94 is a stiffener.
  • the device 10 further includes a plunger sub- assembly, comprising a plunger drive plate 96 in the form of a disk having an internally threaded opening 98 provided axially centrally therethrough.
  • An externally threaded drive screw 100 is threadedly received in the opening 98 and has a disk-shaped plunger 102 mounted on the forward end thereof.
  • This sub-assembly- is.** hown-.including an annular boss .L 4. coaxially centrally formed on the forward face of the plunger drive plate 96, and an annular washer 106 received on the drive screw 100 axially between the plunger 102 and the plunger drive plate 96.
  • the plunger drive plate 96 radially outwardly of the boss 104 includes a circumferentially extending outer peripheral region 108. In this latter region, the plunger drive plate 96 is abutted to the rear end of the ring gear member tubular body thus uniting these two elements into one by frictional contact only.
  • the drive screw 100 extends through the opening 92 and along within the upper compartment 110 and near the rear end thereof is provided with a peg 112 affixed thereto, which extends upwards and out of the slot 88.
  • the purpose of the peg 112/ slot 88 arrangement is two-fold. First, this arrange ⁇ ment prevents the drive screw 100 from rotating relative to the body 12, yet permits the drive screw 100 to move axially relative to the body.
  • gradations 114 may be marked on the exterior of the body 12 beside the slot 88, whereupon the position of the peg 112 relative to the ' gradations 114 may be taken as an indication of the relative fullness/ emptiness of the container A, since the peg 112 will be positioned relatively rearwardly (as shown in
  • Elements 116 are provided for preferably removably securing the region 14 of the body 12, preferably at plural sites-"*along its--length, e.g ' . by straps, clips, clamps, adhesive, screws, hooks or .a combination thereof; what is shown at 116 is typical.
  • the device 10 is mounted on a rotary power tool R via elements 116 and the chuck T is tightened onto the shaft 76.
  • a filled container A is placed in the receiver 24 with its open spout C protruding forwardly as shown.
  • the container is secured, in place, e.g. by securing the toggles as at 36.
  • the rotating chuck T will, via transmission elements 72, 54, 52 and ring gear member 38 cause the plunger drive plate " 96 to rotate.
  • the latter acting on the drive screw 100 which is constrained against rotation by the peg 112 will move essentially axially forwards.
  • the plunger 102 will press forwards on the piston ⁇ causing the piston E to slide forwards, pressurizing the viscous plastic contents H and expressing the contents in an extruded bead or ribbon out of the open tip L.
  • Dispensing is continuous for so long as the trigger S is compressed, until the container is effectively emptied. Dispensing may be stopped before the container is empty, by releasing the trigger S. usually in such an instance some contents H will con- tinue to be expressed out of the tip L until pressure in the container is equalized; dispensing can be more rapidly terminated upon release of the trigger S if the user puts the transmission 72 in reverse and squeezes the trigger S again for a shorttime to back off the plunger 102 a little from the piston.
  • the 120 is a pinion gear with an internally threaded bore by which it is mounted on the drive screw 100.
  • Items 126 are washers serving as spacers and as bearings. The stub ends of the shaft 118 jounal the sub-assembly 117/118/119 for rotation about its axis in the body 12'.
  • the third embodiment is similar to the second excepting that, because the drill R' in this instance incorporates its own forward and reverse switchable transmission (a conventional provision on many such drills) , the need for a separate reverser 72 is eliminated " . Accordingly, the remaining corresponding transmission elements are correspondingly numbered, but raised by 100 and no further description is believed to be needed.

Abstract

Un outil rotatif a main entraine par une force motrice (R) avec un mandrin rotatif (P) est couple a un conteneur de distribution du type a piston de poussee (A) par l'intermediaire d'un adaptateur (10) qui se monte sur l'outil et est fixe au mandrin. L'adaptateur possede un plongeur (102) monte sur l'extremite d'une vis non rotative (100). Lorsque la gachette (S) de l'outil est actionnee, une transmission (18) sur l'actionneur est sollicitee pour faire avancer la vis et le plongeur, faisant ainsi avancer le piston sur le conteneur de distribution. Dans le mode preferentiel de realisation, une goupille (112) fixee sur la vis d'entrainement et se projetant hors de l'adaptateur possede une double fonction empechant la vis d'entrainement de tourner et indiquant la quantite relative de contenu restant a distribuer jusqu'a ce que le conteneur soit effectivement vide.
