- valve member 126 in both valves is in its lowermost .position, i.e. with the upper valve seat 118 closed when the trigger member assumes its intermediate, neutral position shown in dotted lines in FIG. 2, while the valve member 126 of the valve 70, in the following referred to as the pressing valve, is moved to its opposite position when the trigger is pressed inwardly so that the trigger portion 100 raises the lower valve head 124 into engagement with the valve seat 120; correspondingly the valve member 126 belonging to the valve 72, in the following referred to as the return valve, will be raised to shift the valve position when the trigger 98 is pressed forwardly, this position being shown in full lines in FIG. 2.
- the air pressure will be transmitted from the inlet bore 60 through the channel 66 to the upper portions of the valve bores 62 and 64, where the air pressure will serve to close the upper valve portions 118, 122 of the valves 70 and 72 in case the trigger 98 is not influenced byany operating force.
- the two valve members will automatically adjust the trigger to assume its neutral position in which the air pressure is not transmitted further than to the said bottom portions of the valve bores 62 and 64.
- valve positions When the trigger 98 is pressed forwardly by means of a finger behind the trigger, the valve positions will be as shown in FIG. 2, where the valve 70 is closed inthe upper part and open in the lower part thereof, while in the valve 72 the upper part will be open and the lower part closed'.
- the air pressure will be transmitted to the interior of the valve 72 and through the radial holes 114 to the exterior of the intermediate valve portions 112. Therefrom the air pressure will be transmitted further through the channel 82 in the socket piece 14 and into the chamber 34 behind the socket piece.
- the piston system 16, 18, 20 will be forced to move backwardly when compressed air is introduced into the chamber 34 so as to exert a pressure on the front side of the rear piston 18.
- the corresponding backwardly directed movement of the front piston 16 is used for charging the gun cylinder 10 in a manner to be described below.
- the chamber 34 may be referred to as the return chamber.
- each of the chambers 32, 36 behind the two pistons will be reduced, but no overpressure will be produced since the air from the chamber 32, in the following referred to as the front pressing chamber, may escape through the chanel in the socket piece 14, the intermediate portion of the bore 62, the radial holes 114 in the valve 70, the interior of the valve 70, and the open lower valve portion thereof out into the free space around the trigger member in the pistol grip.
- the air from the rear or second pressing chamber 36 may escape along the same way after having been pressed out into the front pressure chamber 32 through the piston rod channel 26 and the side hole 28.
- the piston system For charging the gun the piston system is pressed to its front position shown in dotted lines in FIG. 5, where the front piston 16 is situated almost at the outer end of the front cylinder 10.
- the end cover 38 is released from the cylinder mouth and swung back to its rear position as described hereinbefore and as shown in FIG. 5.
- the gun isheld in the position shown above a putty pail 150 and the mouth of the gun is lowered into contact with the surface of the putty.
- the operator With a finger behind the trigger 98 the operator now pushes the trigger forwardly to thereby connect the return chamber 34 with the source of compressed air so' as to cause. the piston system to move upwardly in the gun.
- the gun will be sucked down into the putty, and the operator follows this movement of the gun.
- the operator pulls the gun up from the putty, preferably by giving it a slight turn for loosening any putty adhering to the exterior surface of the cylinder 10.
- the surface of the cylinder 10 is preferably completely smooth, while also the securing or fastening means for the end cover 38 are located in good distance from the mouth of the cylinder so as to cause no troubles in this respect.- After having charged the gun in this manner the operator now brings the end cover 38 to its locked working position as described in connection with FIG. 4, whereafter the putty gun is ready for further use.
- a modified embodiment is schematically shown in FIG. 6 and comprises a front cylinder 160 corresponding to the cylinder 10 in the embodiment described hereinbefore, an end cover 162 therefor, :a rear cylinder 164 of enlarged diameter behind a rigid wall ring portion 157, and two pistons 165, 166 located in the corresponding cylinder portions and rigidly interconnected by means of a piston rod 167.
- a trigger operated valve system (not shown) corresponding. to the system already described and connected with both ends of the cylinder portion 164 by means of tubes 168 and 169 in such a manner that compressed air is introduced into the cylinder through the tube 169 when the trigger is pressed inwardly while the air is introduced through the tube 168 when the trigger is pushed forwardly.
- the wall portion 157 may well be. inwardly extended so as to be closed around the piston rod 167; in this case, however, the room'behind the piston 165 must have an opening to the atmosphere.
- FIG. 7 A further embodiment is schematically illustrated in FIG. 7, where a gun cylinder 170 contains a non-rotatable but slidably arranged piston 172 adapted to be driven by a rotatable, screw threaded center spindle 173 mounted in a rib supported front bearing 174 and in a rear bearing in a wall 175. Behind this wall the spindle 173 has a gear wheel 176 in driving connection with a driving wheel 177 having a backwardly extending shaft 178 to be releaseably coupled to the chuck of a hand motor 179. When the motor 179 is activated the spindle 173 will be rotated so as to move the piston 172 in one direction.
- the motor 179 may 'be of the reversible type, or the gear wheels 176, 177 may form part of a gear wheel system provided with a handle for controlling the direction of rotation of the spindle 173 in case the shaft may be rotated in one direction only.
- provisions may be made for enabling an adjustment of the velocity of the return stroke for adapting the performance to the requirements of the particular substance, for example more or less cold or viscid putty, such as obtained by means of the adjustment screw 78 in FIGS. 1-5. If desired a similar arrangement may be provided for adjusting the pressing force.
- the device may be provided with a built-in electric motor whether of the rotating type or operating by axially travelling magnetic fields.
