LIQUID ADHESIVE APPLICATORS OF THE.' HAND TYPE Filed Maron 11. 195
INVENTOR Caf/Cae@ QJ Kfz Y.
lUnited States Patent C LIQUID ADHESIVE APPLICATORS F THE HAND TYPE Clifford D. Keely, West Englewood, N. J., assignor to General Corrugated Machine Company, Palisades Park, N. I., a corporation of New Jersey Application March 11, 195l4, Serial No. 41155620 1 Claim. (Cl. 299-112) My present invention relates to liquid adhesive applicators of the hand type and adapted to apply liquid adhesives-particularly those which are water resistant or insoluble. In the use of liquid adhesives of these types by ordinary methods of application, great difficulties are experienced since any adhesive'left on brushes, glue rolls, or other common means of application, if allowed to set or harden, will no longer be soluble in water and hence not removable by ordinary means.
It is therefore a principal object of my invention to provide a liquid adhesive applicator of the closed system type, comprising a hand movable, liquid adhesive discharging jet or nozzle suitable for use with water resistant adhesives.
A still further object is to provide such a device having incorporated therein a positive acting electrically controlled valve which will not be subject to leakage of the adhesive either into the discharge jets or exterior of the device. Thereby the improved device will not drip adhesive following the shutting oif of the valve.
A still further object is to provide such a device in which the electrical control is mounted on the handle thereof.
A still further object is to devise an improved valve for dispensing water resistantliquid adhesive.
Other objects of my invention and advantages thereof will be apparent as the description proceeds and the features of novelty will be pointed out in the appended claim.
For a fuller understanding of my invention, reference may now be had to the following detailed description taken in connection with the annexed drawings in which:
Figure 1 is a view in longitudinal section of an illustrative embodiment;
Fig. 2 is a view taken on line 2 2 of Fig. l showing the solenoid casing;
Fig. 3 is a view taken in section on line 3--3 of Fig. 1;
Fig. 4 is an isometric view of a portion of the casing of the device;
Fig. 5 is a view in section on line 5-5 of Fig. l showing the cross section of the valve proper; and
Fig. 6 shows the assembled device including the source of liquid adhesive.
In the drawings, 10 denotes the casing, one separable portion 11 of which is shown in Fig. 4. For convenience, casing 10 may be made of die cast vplastic material of any suitable nature and may contain a chamber 12 for a solenoid 13, a chamber 14 for electric switch 15, Fig. 3, and a chamber 16 for conduits supplying electrical energy and adhesive, section 11 and complementary section 17 being secured by screw bolts variously disposed, such as Nos. 18, 19, 20.
Liquid adhesive under pressure is supplied by flexible tubing 25 to a conduit member 26, the union of said member and said tubing being effected by means of a threaded nipple 27 crimped or otherwise joined to said tubing. Conduit member 26 receives the solenoid con- 2,768,861 Patented Oct. 3Q, 1956 ice trolled valve casing 28 by virtue of the fact that the same is screw threaded into a bore in said conduit member 26 as clearly shown in Fig. l, such casing being 0f brass or other non-magnetic metal and containing the valve proper 29 integral with armature 30. Surrounding said casing 28 is the solenoid winding 31, the ends of said winding being joined to wires 32, 33, carrying the current from the usual house or factory source. In circuit with said wires is a switch 15, preferably of the known push button type, the same being disposed within said chamber 14. Casing 28 has a threaded stem 35 terminating in a nut 36 which aids in holding the various parts tightly together including the outer casing 37 of the solenoid winding 31. The valve proper 29 registers with an oppositely disposed recess or valve seat 39 so that when the valve descends in response to the action of helical spring 40, the flow of adhesive will be stopped. The valve-armature 30 is provided preferably with a central bore 42 and one or more milled grooves 43 whereby when the casing 28 is iilled with adhesive, the easy movement of the armature through the surrounding liquid is permitted.
Joining member 26 and constituting a continuation thereof is duct 44, the parts being connected by the threaded bell joint shown. At the remote end of duct 44 is one or more, as for example two, nozzles or jets 45, 45. While the latter may be composed of any suitable material, the tetrauoroethylene resin plastic manufactured by the Du Pont Company under the name of Teflon is preferred since it is of such a nature that the adhesive has little tendency to adhere to it. The bores of said nozzles preferably are of such diameter that their combined flow capacity is not substantially greater than that through duct 44 whereby the tendency of the jets to drip after the How is shut o is further minimized. Mounted on the duct 44 is preferably a guide roller 47 serving to support the hand applicator and facilitating its movement during the adhesive applying operation. Functionally, the numbers 26 and 44 constitute one integral unit. However, by means of the construction shown, other ducts having different members and sizes of nozzles may be interchanged.
In use the electric conduit represented by wires 32, 33 may be plugged in to a source of current and the air above the liquid adhesive in the jar 52 pumped up to pressure. Then having placed the nozzles 45 above the work, the valve is opened by depressing the push button 15 and the entire hand applicator moved along the desired line of glue application, aided if desired by means of the roller 47. When the iinger or thumb releases the push button 34, the flow of glue stops nstantly without dripping. When the device is not in use, the jets 45, 45 may be suitably covered to prevent hardening of the adhesive as by means of a hose section slidable over the end of duct 44.
It will be noted that because the system of applying the adhesive in the improved device is closed, the same is always ready for use without the necessity of cleaning whereby it is readily adaptable to the application of quick-setting waterproof adhesives.
This application is a continuation in part of my c0- 3 pending application Serial No. 337,708, tiled February i9, 1953.
It will be understood that various changes will occur to those skilled in the art without departing from the spirit of my invention or the scope of the appended claim.
I claim:
A liquid adhesive applicator adapted to apply liquid adhesive of the water resistant variety, said applicator being of the hand type, and comprising in combination a nozzle, a substantially rigid duct communicating therewith, a valve casing in said duct having a valve proper without mechanical communication with the outside of said casing, magnetic means for operating said valve proper, a exible conduit supplying electric current thereto, a handle to which said duct and said conduit supplying electrical current are secured, a source of liquid adhesive under pressure, a exible conduit connecting said source last mentioned with said duct adjacent the inlet end of said valve, a switch disposed upon said handle and controlling the flow of said electric current, and means mounted upon said duct and facilitating the movement of said applicator upon the Work.
