The coil 23 has one end terminating in a loop extending upwardly and is operatively connected with the end of the conductor 40. The other end of the coil 23 terminates in a loop forming a conductor 41 i'as tened to a binding post 44.. The loop extensions of the coils 23 are each covered with a plurality of porcelain insulators as and the conductor 40 is also encased with insulation 49. such as asbestos or the like at its junction with the loop extension of coil 23 to prevent possible contact of the conductors or loop extensions with the housing 17.
The conductors 41 and 42 are operatively connected and disconnected by a thermostat control device suitably mounted in a cup shaped member 50. The member 50 is detachably mounted on the plate 14 by a threaded pin 51. The thermostat control device is adjusted to disconnect the conductors 41 and 42 at a predetermined temperature and to again connect the conductors when the temperature has dropped a few degrees by reason of the circuit being broken. conductors 41 and 42 are respectively connected. with the thermostat by binding posts 46 and 47.
The thermostat consists of an upper bar 53 underneath which is positioned a disc shaped mica plate 34 overlying an annular metal disc 55. A mica disc or plate 56 underlies the annular disc and the various discs and plates comprising the thermostat are clamped together by the binding posts 46 and 47 and by a binding post 5s. The binding posts 47 and 59 are each separated 1 from the bar 53 by mica washers 52 and have contact members 57 and 58 respectively, mounted on their lower ends. The binding posts 47 and 49 are surrounded by insulating material as shown and are connected with a resistance coil 1 39 through the medium of the binding post 46 and a plate 60. A bolt 61 projects through the center of the various plates and discs forming the thermostatic device and has the plate 60 mounted on its lower end. The plate 60 is clamped between the head of the bolt and a washer 62. The upper end of the bolt 61 has a nut 64 separated from the bar 53 by a washer 63 and the position of the plate 60 relative to the contact members 57 and 58 is easily adjusted by means of the nut. The plate 60 is concave upwardly taking the general form of a segment of a sphere with its outer edge portions normally in contact with the members 57 and 58. The resistance coil 39 connects the binding posts 46 and 59 and thereby completes the circuit between the conductors 41 and 42 when the plate 60 is in contact with the members 57 and 58. The plate 60 is so constructed that it remains in contact with the members 57 and 58 until the thermostat reaches a predetermined maximum temperature which so distorts the plate as to bend it to the dotted line position shown in Fig. 4 and thereby breaks the connections between the members 57 and 58. The temperature at which the plate 60 is so distorted as to break the circuit depends upon its size and thickness and also its curvature. Further detailed description of the thermostat is omitted since the specific thermostat shown is not considered as part of the invention.
In using the device for branding meat the characters 37 are applied to a pad and thereby coated with ink, following which the device is quickly raised to a temperature suihcient to dry the ink as the characters are pressed against the surface to be marked. It is found in practice that temperatures ranging between three hundred forty and three hundred seventy degrees Fahrenheit are sufficiently high to dry the ink as it is being pressed into the surface oi the and suificiently low to avoid the melting of the fats. If the characters are heated to temperatures above three hundred seventy degrees the fat is melted and the ink and oil run together providing letters having a smeared and blurred boundary and presenting a generally unattractive appearance.
The thermostat shown and described preicrably breaks the circuit at substantially three hundred seventy degr es Fahrenheit and again opens the circuit when the temperatures drop to approximately three hundred forty degrees. No claim is made to the specific thermostat construction shown and described as such construction is well known in the art and any thermostat operable at the temp *ratures named can be used. The invention consists in the provision of means adapted to heat the type and the ink to temperatures above that named and in combination with a thermostat control means adjustable for maintaining the temperatures within a predetermined narrow range.
Thus it will be seen that the device provides a novel combination of type and thermostatic controlled means for heating the type within a range of temperature adapting the device for marking cold meat whereby the ink is dried as it is applied and caused to penetrate the meat without melting the fat contents of the meat.
Having thus described my invention, it is obvi ous that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form,
construction, arrangement and combination of parts herein shown and described or uses mentioned.
