Application June 12, 1939, Serial No. 278,623
4 Claims.
This invention relates to marker instruments that may be used for applying a colored fluid to fabrics or other articles for marking them in any manner desired. The invention includes a marker instrument which is provided with a fusible marker compound which is normally in a solid state but which is reduced to a fluid state for application purposes by the use of an electric heating element incorporated in the instrument. The instrument is provided with a nozzle having a liquid chamber for receiving the melted compound and which is released in a fiuld state by a ball valve on the point of the instrument. The invention also includes means for feeding the fusible compound to the electric heater; a. radiator in the liquid chamber heated by the electric heater for maintaining the fluid in a liquid state as it is used. The invention also includes a heat insulating medium for the shell of the device so that it can be conveniently used by the operator.
These and other objects of the invention will be more particularly understood from the following specification and the accompanying drawing, in which:
Fig. 1 is a longitudinal section of one form of a thermo-electric marker embodying this invention;
Fig. 2 is a cross section on line 2-2 of Fig. 1;
Fig. 3 is a cross section on line 33 of Fig. 1;
Fig. 4 is a longitudinal section of another form of the device, and
Fig. 5 is a cross section on line 5-5 of Fig. 4.
This invention is for use with a solid marking compound which is applied in the liquid state but which, normally, remains solid and can be as conveniently used as a markin crayon or pencil. The marking compound contains a mixture having the required color pigment and a binder that has a quick break in viscosity which will readily flow through a small orifice. It should not soften below 130 degrees C. The binder may be a resin which, after application, will solidify into a thin film which is reasonably flexible and will hold on fabric. A fiexilizer may be added to the compound to increase its fiexibility and this will depend somewhat on the degree to which the compound will fuse. For ordinary purposes, and when applied to a fabric, the melting point should be above the heat of the water in which the fabric may be processed but the melting point must be within the range of the electric heating element with which the instrument is provided.
The instrument comprises a tubular holder which forms a handle for the marking device corresponding to the handle of a pen and the end is provided with a nozzle having a ball valve by which the marking compound, in a liquid state, is released for marking purposes. The marking compound is located in the tubular holder and is forced forward to the nozzle by a spring. The nozzle, or the writing end of the instrument is provided with an electric heating element which is connected in circuit when the instrument is in use and which fuses the compound at the nozzle, filling a chamber in the nozzle with liquid to be used through the ball valve. The liquid chamber is provided with a radiator which maintains the liquid that has been melted in aliquid state as it is used for marking purposes.
In one form of the device the electric heating element is located inside the tubular holder and has a central conduit for the electric conductors around which the marking compound is placed. In another form a cylindrical marking compound is located in the tubular holder, outside the tubular holder the electric heating element is placed and outside the heating element a heat insulation is provided to enable the operator to use the instrument in the heated state.
In the drawing, II is the nozzle which is provided with the point I2, having a spring seated ball valve II which connects with the liquid chamber ll in the nozzle and in which chamber the radiator l5, connected with the electric heating element It projects and provides the heat necessary to maintain the compound in chamber ll in a liquid state. A central tube I! passes through the holding tube 23 and connects with the heating element It, the electric conductors I! for the heating element may be located in tube l'l. Around the tube I! the fusible marking compound is placed as indicated by the semicylindrical members I9 and 20, Fig. 3. These members are split longitudinally so that they can be replaced without threading on th central tube ll. These members are held in place by the cup shaped washer 2| which may be provided with a heat insulated washer 22 to prevent the spread of the heat from the compound to the outer end of the instrument. The shell or holder 23 is provided with screw cap 24, having an orifice through which the tube l1 passes and which engages the coil spring 25, located between the cap 24 and the washer 2| to feed the compound I8, 20, to the nozzle as it is melted away by the electric heater l8 located at the discharge end of the device. There is a clearance between the heater l6 and the tube 23 and also between the members I 9 and 20 and the tube 23 which enables the fused compound to flow into the chamber I4.
Opposite the marking compound the device is heat insulated as indicated by the insulating jacket 21 around the tube 23 and held in place by the cylindrical cover 26. This jacket is supported by collar 35 on the tube 23 and tapers around the nozzle H a indicated to insulate the portion of the instrument where the heat is applied. The heater is located at the point of the instrument and away from the body which forms the handle.
In the construction of Fig. 4 the electric heating element 36 is applied to the outside of the tubular holder 23 and is held in place by the jacket 32. Over this jacket the heat insulator 21 is placed and is held in place by the cylindrical cover 34. This construction is held in place by the collar 33 at the outer end and by the collar 35 at the pointed end. The conductor 31, leading to the heating element 36 is controlled by the spring switch 38, connecting with conductor 39, embodied in the circuit of the electric heater so that when the device is not in use the circuit of the heater is automatically opened.
Th nozzle II is provided with radiating fins |5a opening into the chamber a of the nozzle to fuse the compound 3| which is fed forward by the cup shaped washer 2| and spring 25. The tension of spring 25 on the compound 3| is regulated by stem 3|, connected to 2| and adjusted by the knurled nut 40. This prevents the nozzle from overfeeding and choking with the partially melted compound.
The marking compound for this device can be manufactured and stored in a solid state and does not deteriorate. The semi-circular form of the compound indicated in Fig. 3 enables the compound to be replaced around the tube |1 without interfering with the electrical connections.
This invention relates to the general type of marking instruments shown in co-pending application 245,890 filed December 15, 1938.
