The diiierent items shown in the schematic circuit diagram (Fig. 6) are all standard equipment and are used as auxiliary to, and in conjunction with, the device of this invention.

. Circuit diagram,

In the foregoing specification, it should be noted that tne nve-way valve reierred to is a vaive which has two positions and that the valve'is positioned in one extremity or the other of its move ent by certain, solenoid control means provided therelor. I y y I Reference now should be had to the schematic circuit diagram shown in Fig. 6 of the drawings. In this figure it is seenthat two powersupply lines Hill and 19! are provided which supply electrical energy for operation of the entire apparatus of the invention. The lead connects through a lead 32 to a thermostat {03 that controls a switch I64. with the other side of the switch 104 being connected to a resistance heater unit, 405, that'is located in the iron l5 used in the device of the invention. The other side of the heating element hi5 connects back to the power supply lead 'lil'l so that when the main control switolr li is closed, electrical energy will be supplied to the'heat element I05 as long as the thermostat, 103 is closed. The signal light Slis provided in parallel relation to the thermostat 133 by, wires ml and H18 so that when the thermostat is open, the circuit there around is through the light, I06 and causes such light to be lit and indicate that the thermostat is open whereas when the thermostatis closed, it effects a short circuit around the light 106 and prevents operation of. the light. This'thermostat I03 is associated with the heater resistant unit; it5 fso that the thermostat is opened "by such heater resistorwhen' at. a predetermined temperature, such as about 400 F., so that heat energy will be supplied to the resistor I05 until'it reaches a predetermined temperature. When the thermostat'lil3 is open, the light 106 absorbs somuch energy that only a very low current flows through the register (95, and does not effectively heat same.

In starting up the "apparatus of the invention, it is, greatly desirable that the heater unit be retained in its up position until the device is ready for operation. Thus aso-called blocking thermostat I09 is provided for controlling a switch III]. This switch H6 is connected by a lead Hi to one, terminal of a solenoid coil or solenoid H2. The other terminal of the solenoid i [2 is connected by a lead I 3 to the power supply lead 161., Lead 11 4 connects the power supply lead [82 to the other terminal of the thermostat we so that when the blocking thermostat I09 is closed the solenoid I I2 is continuously energized and retains the five-way valve device in a fixed position to set up pressure in the cylinder 4 to retain the piston rod thereof in its up position.

When the heating resistance I05 of the iron ly open foot control switch or the automatic switch of the apparatus of the invention. For the so-called semi-automatic operation of the invention by use of the foot switch referred to hereinbefore, a foot controlled switch H5 is connected to the power supply lead I90 and connects to a lead IIB that connects inturn to one terminal of a second solenoid In that is associated with the two position valve for controlling the setting or operation thereof. The other terminal of the solenoid III connects through a lead II8 to the remaining power supply lead IIlI so that closing the switch I I5 instantaneously causes the solenoid III to be energized and moves the valve to its down position. Such position of the valve provides air pressure supply to the tube ID for forcing the piston rod downwardly of the cylinder in which it is slidably received and causes the iron head to move down into desired relationship with the goods on which a transfer is to be applied. Such pressure being transmitted to the conduit or tube It) also is carried to a conduit I28 which connects to a pressurestat I2I the pressure in and setting of which controls a switch I22. Thus when a predetermined pressure is set up in the line I and through it to the line I20, the pressurestat I2I will close switch I22. Such action occurs only when the pressure in the line I0 has forced the piston rod therein to move downwardly of the cylinder 4 to the bottom thereof. By controlling the setting of a valve I23 that is provided in the line I20 and has a variable escape, or relief orifice provided wherein, the rate of build-up of pressure in the pressurestat I2I can be controlled to a desired value. Control rheostat 35 controls the size of the orifice in the valve I23. Thus after the piston rod I has moved to its lower extremity, a certain predetermined time will elapse before the pressurestat I2I is actuated to close switch I22. Closure of the switch I22, which connects at one side to the power supply lead by a lead I24, closes a circuit through the effects actuation of the solenoid II2 by means of a connector lead I25. This actuation of the solenoid I I2 will cause the control plunger for the five-way two position valve to be changed so that pressure will be supplied to the line or conduit II and effect a lifting movement of the heater iron and associated elements. It has already been noted that the solenoid H2 is connected to the power supply lead I OI by a connector lead II3.

In case it is desired to have automatic operation of the apparatus of the invention, the switch element I 6 previously referred to herein is shown on the drawing in parallel relation to the foot control switch II5 so that when such switch is closed, as by properly positioning same plus movement of the heater iron and its associated means to its up position, the apparatus of the invention can be made to repeat its operative cycle, as desired by the operator of the machine. Leads I26 and I2? connect the automatic switch I6 in shunt or parallel relation to the foot control switch I I5.

Usually it is necessary to have a slight time lag between the raising of the heater iron member and the next downward stroke thereof, even on automatic operation of the machine. so that it is desirable to have a second pressurestat control provided in the apparatus of the invention and connected in the line I I. This pressurestatis indicated by the numeral I 28 and in turn controls a switch I29 that is provided in the lead I2'I so that a circuit only is closed through the automatic switch after a predetermined pressure has been built up in the lower portion of the cylinder 4. Rheostat 36 may control a vent orifice associated with the pressurestat I28 to regulate the time delay of the apparatus intermediate its operational cycles, similar to the connection and action of the valve I23.

As yet another feature of the apparatus of the invention, the safety control bracket I9 is connected to the switch III] to close same and effect an immediate energization of the solenoid II2 when the operators body or. person strikes this control bracket I9 on its downward movement. Thus an immediate lifting action is exerted upon the piston rod I and associated means. The tube 9 connects to the five-way valve A to receive the exhaust from such valve when the piston is being raised through action of the solenoid II2.

Air pressure is supplied to the system bya conventional air compressor pump I40 that is driven by a motor MI. Motor I4I connects to lead I 24 and by lead I42 to power supply lead IOI. Output of pump I 40 flows through tube I43 to the valve A. A counter device 40 is connected by lead I45 to lead I I6 and by lead I46 to lead IOI to indicate the number of operations of the machine.

It has been established that it takes the correct amount of pressure, correct temperature, and the correct length of time for a heating element to remain in contact with a transfer to make the desired transfer and mark the cloth or fabric to be marked. Such length of time is regulated by the time indicator rheostat 35, which has a dial with two different markings, namely, light and heavy, to control the length of time that the iron I5 remains in contact with the dry transfer and cloth or fabric to be stamped. A pressure dial 39 is connected directly to the air supply line I43 for the five-way air valve A. .By turning the knob 35 to heavy, the iron I5 is allowed to remain in contact with the "dry transfer somewhat longer than at light in order to properly mark such cloth.

The safety switch bar I 9 has a spring I 9A that is secured to and moves with the iron, and draws the bar I9 to a normal non-operative position. Either by a slight upward pressure or touch by the operator, or by contacting the hand of the operator when it acts as an emergency to prevent injury to such operator, the switch bar closes theswitch III] to immediately stop the downward stroke of the iron and returns it to its up position.

The operation of the iron or heating elements is further controlled by means of the combination automatic interference and safety switch III! located within the body of the heating element and which acts to automatically cause the machine to cease operating if for any cause the heating element has dropped to the point where it is impractical to correctly apply transfers. This switch will also prevent the operation of the machine in case the operator attempts to use the machine before waiting the period of time for the heating element to acquire its proper temperature.

It will be realized that friction is the only force normally preventing movement oi the, piston I, Conduit. 2GB of valve 7A., is an, exhaust line there: for. .Thecontrol arm t8 issuitably pivotally secured to the, movable ,head or iron assembly of the device .otthe invention.
