  • Thepresent invention relates generally to ejecting 5 devices, and more particularly to devices for ejecting putty and analogous materials.
  • one feature of the invention resides, in a device of the character in question, in a combination which comprises a cylinder, a piston reciprocable 'in the cylinder between a suction position and an expulsion position, and drive means for reciproeating the piston.
  • the drive means includes speed regulating means operable for moving the piston from the expulsion position to the suction position at a higher speed than vice versa.
  • the motor is advantageously an electromotor whose torque becomes automatically adjusted in dependence upon the resistance encountered by the piston during its expulsion stroke.
  • the motor may be a direction-reversible motor, for instance a direct current reversible motor, and an electronic regulating device can be provided which regulates the torque and therefore the force exerted upon the piston, largely independently of the RPM setting of the motor.
  • the cylinder as well as the ejection nozzle are advantageously readily removable, for instance by being threadedly connected with a portion of thehousing, so that the device can be readily accommodated for different uses as well as to the particular material which is to be ejected.
  • the piston isto be advanced at speeds of up to be cm/sec. during its expulsion stroke.
  • the novel device is particularly easily usable, that is it can be readily handled.
  • the arrangement for controlling the operation of the drive means is such that the same hand which holds the device can also control this arrangement, for which case the device advantageously has a housing provided with a pistol grip.
  • reference numeral 10 identifies the device in toto.
  • the drive housing portion 11 which may be of syn-1 thetic plastic material, or of another material, and a cylindrical housing portion 12 which is advantageously of steel.
  • the portion 12 is connected with the portion 11, advantageously in a manner so that they'can be readily separated, for instance by means of a sleeve 13 or a screw threaded connection.
  • the free front end of the portion 12 is provided with an injection or spray nozzle 14 which is also readily releasably connected with it, in the illustrated embodiment by means of a screw connection 15.
  • the housing portions 11 and 12 together have a somewhat pistol-shaped configuration, with the housing portion 11 constituting a pistol grip which is to be surrounded and engaged by a hand 'of a user and which can be further adapted in a shape to more effectively fit the hand.
  • the housing portion 1 1 is essentially of two-part construction and has a motor component 16 and a gear component 17 which can be connected with one another or constitute a common housing.
  • the motor component 16 accommodates the diagrammatically illustrated electromotor 18, which is too well known to require a detailed description.
  • This motor 18 may for instance be a reversible direct current motor which drives, via a step-down drive 19, a pinion 20.
  • the latter is in mesh with a toothed rack .21 which is displaceable transversely to the axis of the motor drive in the direction of the arrows x x
  • the rack 21 at the same time constitutes the piston rod of the piston 22 which is reciprocably accommodated .in the housing portion 12.
  • the rack 21 is journalled at 23 and 24 in the side walls of the housing portion 17 for sliding displacement in the direction of the aforementioned arrows.
  • the free end 25 of the rack 21 projects from the housing at the side which is opposite or away from the piston 22, but the rack 21 is still guided in the housing.
  • a sealing or cover arrangement 26 be provided (shown in broken lines) which may for instance be in form of a bellows, so that when the piston 22 and the rod or rack 21 are displaced in the direction of the arrow x the free end 25 which moves out of'the housing portion 11 is covered by the arrangement 26.
  • This not only provides for a seal but also provides for a protection against the possibility that the user might be injured, for instance by having a finger clamped between the rack 21 and the housing.
  • the piston 22 itself can be removably mounted on or connected with the rack 21. Because of this, the rack 21 is provided with a plate 22a having a smaller diameter than the piston 22. With this arrangement it is'possible to be able to use in the device according to the present invention so-called cartridges which each have a cylindrical container and can be inserted into the cylinder 12, and each of which contains not only the material to be ejected but also its own piston. Evidently, with this arrangement the piston 22 is not required and can be unthreaded from the rack 21, whereupon in use the plate 220 presses against and operates the piston of the cartridge.
  • An electronic control device 27 is advantageously arranged separately of the remainder of the device and connected with the drive thereof by a flexible cable 28 which may have any desired length.
  • the device 27 can be connected with an external source of electrical energy, identified with reference numeral 30, for instance a net of 220 volts, or as indicated at 31 with a battery 32.,0f course, the arrangement can be such that the device can be connected at will either.
  • a transformer and a rectifier for transforming the net voltage to the necessary mode of voltage, for instance of 12 volts, can be made a partdrive 20, 21 which is located away-from the housing portion 16. It may be operated by a control element 34, for instance in form of a turnable knob.
  • the device 33 in conjunction with the electronic control unit 27, permits an adjustment of the RPM setting of the electromotor 18. Switches 35 and 36 can be operated by the fingers of a user whose hand grasps the housing portion 1 1.
  • the switch 35 may serve to energize the drive in a sense causing the piston 22 to advance to its expulsion or forward position in the direction of the arrow x and the switch 36 may serve to energize the drive to cause the piston to be retracted from expulsion position to suction or retracted position in the direction of the arrow x It is advantageous if the arrangement is such that the drive motor is switched on only when one of the two switches35 or 36 is depressed.
  • the electronic control unit 27 can control the motor, for instance via I position, for instance because a different type of material is to be expelled, the motor will supply a correspondingly higher torque and be in turn supplied for this purpose with a correspondingly increased amount of electrical energy.
  • the device 27 can be made to form a housing unit with the housing 11, if desired, and as an alternative the device 27 can form a portable unit together with the battery 32.
  • the cylinder 12 has a diameter of approximately 5 cm and-a length of approximately 35 cm, although these are of course exemplary figures.
  • the nozzle 14 In order to fill the cylinder with the substance to be expelled, the nozzle 14 is unscrewed and the piston 22 is retracted, while the open front end of the cylinder is immersed in or otherwise connected with a source of supply containing the material. This causes material to be drawn into the cylinder 12. Thereupon, the nozzle 14 is threaded back into place and the piston 22 is then made to advance to its expulsion position, causing the expulsion of the material through the nozzle 14. When the piston has reached its expulsion position the piston is briefly retracted for instance by brief operation of the switch 36 or automatically, so that dripping of the material from the, cylinder is avoided.
  • FIGS. 2 and 3 The embodiment in FIGS. 2 and 3 is analogous to that of FIG. 1,'and like reference numerals identify like elementsexcept that in FIGS. 2 and 3 each reference numeral has been given a prefix.
  • Reference numeral 111 identifies a drive housing portion which may be of synthetic plastic material.
  • a cylindrical housing portion 112 is advantageously of steel and is again removably connected with the housing portion 111 by threaded means or by the sleeve- 113.
  • a threaded connection is provided by means of which the nozzle 114 is connected with the housing portion 1 12.
  • the housing portion 1 1 1 is of several parts and is provide'dwith a rearward motorportion 116, a gear portion 117 and a handgrip'portion 1 160 which in the illustrated embodiment is ofone piece with a portion of the gear portion 117.
  • the handgrip portion 116a is a part of the housing, and a portion 116a of the handgrip 116a .is configurated as a cover via which the interior of the handgrip portion is accessible from outside.
  • the entire device is again of substantially pistol-shaped configuration, and the handgrip portion 116a extends transversely of the elongation of the device, as illustrated.
  • a piston rod 121 is configurated as a screw spindle or provided with helical threads 1210, and a piston 122 is reciprocable in the housing portion 112.
  • the piston rod 121 is driven by a stepdown gear 119a, 11% by the electromotor 18 which is accommodated in the housing portion 116 and arranged in parallel with the piston rod 121a.
  • the stepdown gear comprises a first gear unit 119a and a spur gear drive having gears 120a and 12Gb which are accommodated in the housing portion 127 in such a manner that they cannot be displaced axially.
  • the gear 120b is in mesh with the threads 121a of the piston 121.
  • End switches 137 and 138 (also known as limit switches) shut off the drive for the piston rod 121 and thereby the piston 122 as soon as the piston 122 has reached either its expulsion position or its suction position, respectively.
  • a toggle switch 135 is provided that may for instance assume three positions. It may operate the drive so as to cause the piston 122 to advance to the forward or expulsion position when in position indicated by the arrow x,, to move the piston 122 to the retracted or suction position when in the position indicated by the arrow x and to switch off the electromotor 118 when the switch is in an intermediate position.
  • the retraction of the piston 122 can be effected in that the motor 118 is a reversible motor.
  • the limit switches 137 and 138 can be so arranged that before the electromotor 118 is switched off, a brief retraction of the piston 122 from its expulsion position towards its suction position is carried out, so as to prevent dripping of material from the device.
  • a relay with a time switch can be provided in the electronic system for this purpose,
  • the time during which the piston is so retracted, or the distance through which it is retracted, can be made adjustable, for instance in dependence upon the viscosity of the material being expelled.
  • the retraction can be between 1 and 5 cm, to name an advantageous range. It is also possible to construct the arrangement in such a manner that the piston 122 is retracted briefly and part of the way towards the suction position, when the switch 135 is released by the fingers of a user who grips the handgrip portion 116a.
  • Reference numeral 128 designates a connecting cable which can lead to an external battery, or else to a socket of a current supply net,in which case a transformer and a rectifier will have to be interposed.
  • the electronic control device may be mounted directly on the novel device itself.
  • a potentiometer is identified diagrammatically at reference numeral 139 and may serve for the slower advancement of the piston during its movement to expulsion position, and for faster retraction during movement toward suction position.
  • FIGS. 2 and 3 provides for a bellows 126 or analogous cover which surrounds the end portion 125 of the piston rod which extends rearwardly out of the housing portion 111.
  • a device of the character described comprising a cylinder having an interior at least partially filled with a substance to be expelled; a piston mounted in said interior of said cylinder for reciprocation with respect thereto between a plurality of positions delimited by a forward position and a retracted position and adapted to expel the substance from said interior of said cylinder during its movement toward said forward position and to draw a medium into said interior of said cylinder during its movement toward said retracted position;
  • nozzle means connected to said cylinder and communiquently to the termination of each movement toward cating with said interior thereof for dispensing the substance expelled therefrom; drive means for reciprocating said piston; and retracting means for limited retraction of said piston toward said retracted-position subsesaid forward position to thereby retract the substance present in said nozzle means into said interior of said cylinder and prevent dripping.
  • said drive means further comprises an electromotor. having a torque which is self-adjusting in dependence upon the resistance encountered by said piston during movement to said forward position.
  • said retracting means comprising regulating means for regulating the mounting means mounting said nozzle for ready removal and installation.
  • a device as defined in claim 1 further comprising a housing having a pistol grip; and switch means in said pistol grip for engagement by the hand of a user and associated with said drive means for controlling the operation of the same.
  • said drive means further comprising a gear drive including a gear surrounding said piston rod, and helical threads on said piston rod and meshing with said gear.
