CABLE-MARKING MACHINE.

Application filed. March 9,1927. Serial no. 174,062. 1 e

This invention aims to provide a machine adapted to automatically impress measurement markings on any extremely long article such as wire' or cable. While not limited thereto the embodiment of the invention illustrated is especially well adapted for impressing consecutive numbers at intervals of one foot on a lead sheathed cable as the latter is paid off by the lead press and wound on a suitable, stock reel.

The invention will be apparent from the following specification when read in connection with the accompanying drawings and the features of novelty will be defined with particularity in the appended claims. In the drawings--- 1 is a somewhat diagrammatic view showing my improved marking and measuring machine mounted in juxtaposition to a 2 lead press and storage reel and arranged to impress consecutive numbersrat regular intervals on the cable as it is fed from the lead press to the storage reel;

Fig. 1 is a view of a section of cable showing measurement marks impressed thereon;

Fig. 2 is a diagrammatic view showing in skeleton form the main operating elements of my machine;

Fig.3 is a view similar to Fig. 2 but showing the parts in the position they assume at the ,instant the impression is being made on the cable; i I

Fig. 4 is a detail view on line 4-4 of Fig. 3 illustrating the positionof the contact arm corresponding to the positionof other parts shown in Fig. 3. g Referring in detail to the drawings, 10

1 represents a lead press of known design and construction which is adaptedto encasefa' 4 cable 12 with an outer sheath 14 of lead and to feed the sheath cable from the machine in the direction of the arrow at; A stockreel 16 is supported on suitable rollers 18 and between the lead press and the stock reel is mounted my automatic measuring and marking machine indicated as aIwhole by numeral 20. This machine includes suitable hearing or guide rollers 22 and 24 arranged toensure that the cable passes underneath This wheel is mounted for rotation in the free end of an arm 28 which is 'pivoted at 30to a suitable bracket secured to the frame of a machine.

As the lead sheathed cable is fed from'the '55 lead press 10 to the take-up, orstorag'e roll I t6, the measuring wheel 26 is rotated by frictlonal contact. In the embodiment ofthe invention illustrated, the measuring wheel is of such diameter that its circumference measures exactly four feet, 5 The machine illustrated is intended to impress a mark at intervals of each foot throughout the length of the cable. Therefore, meansare provided so that for each quarter'revolution of the measuring wheel, mechanism to be hereinafter more fully described is set in operation to cause a stamping head to advance and strikea blow. These stamping heads carry type number. wheels which are advanced one step each time the heads are actuated. I preferably provide-two stamping heads so as to simultaneously. impress measurement marks on opposite sides of the cable. Thus if the mark on one side of the cable is mutilated in handling the cable, the .7 chances are the mark on the other side will still be visible.

For simplicity of illustration the operating elements have been shown in skeleton form in Figs. 2 and 3, the frame Work being omitted in the interest of clearness. The machine illustrated is electrically operated and the circuits are diagrammatically shown in connection with the mechanical elements" which they control. The machine includes a pair of stamping heads 32 'of known construction which carry suitable type wheels which are adapted to be advanced one unit each time the stamping head is actuated. These stamping heads are, of known construction and they operateby ratchet mechanism such as found in various numbering machines. Further description thereof will not be made as the construction of the stamping head forms no part of the present invention. Each stamping head is provided. with an outwardly extending finger 34 which strikes a suitable fixed pin 35 arranged to advance the wheel one unit each time the head'is advanced from'the position of Fig. 2 to the position of Fig.3. The printing face of the stamping wheel is indicated at 36.

Each time this face is moved to the position of Fig: 3, a'difi'erent number is impressed on the cable. I he stamping heads are actuated bymeans of a solenoid oi equivalent electro-motive device such as indicated at 38. This solenoid is adapted to actuate a core 40 having secured at the top thereof 'laterallyextending 11o arms 42 connected by links 44 with the stamp head supporting arms 46 which are pivotally mounted at 48.

The energization of the soleno1d ,38 1s controlled by an electromagnetic relay switch indicated as a whole by numeral 50. This therewith is a contactarm 68'carrying a contact roller which is adapted to coact with the four fixed contacts 70,72, 74,- 76 which contacts are located at 90 intervals around the circle. The arrangement is such at terminal 81.

that each time the rdller of the contact arm "68 engages either of the contacts 70, 72,.74

and 76 a circuit will be made through the coil 52 of the relay switch above mentioned, hence, the solenoid will be energized and an impression marked in the cable. However,

in order to prevent the stamping heads from marking the same number twice on the cable' in the event that the measuring wheel should. stop while the contact roller of the arm 68. rests on one of the contacts, I provide a se-' lector switch indicated as a whole by numeral 78. This switch is provided with four contacts 80, 82, 84 and86. The contacts 80 and 84 are connected electrically with the contacts 70 and 74. Similarly, the contacts 82 and 86 are connected with the contacts 72 and 76. These connections are made by conductors 88 and 90. The diametrically op posite contacts 70 and 74 are electrically con nected to the wire 88 at terminal 89. Similarly, the diametrically opposite contacts 72 and 76 are electrically connected tothe wire 90 at terminal 91. Similarly, contacts 80 and 84 are electrically cgnnected to wire 88 Opposite contacts 82 and 86 are electrically connected to the wire 90 at terininal 83.

Coacting with the contacts 80, 82, 84 and 86 is a selector switch contact arm 92 which is secured to a shaft 94 which carries a fourtoothed ratchet 96 which is arranged to be' periodically turned oneuarter of a revolunoid plunger 40., As the plunger reaches the I end of its upward strokea's shown in Fig. 3,

the pawl 98 engages 'thc' uppermost tooth of the ratchet 96 and on downward movement of the plunger 40, the ratchet is moved through a quarter-of a revolution. This arrangement alternately connects the roller carried by the contact arm 92 with the wires;-

' 88 and90 leading, respectively, to the 0 posi te pairs ofcontacts 70, 74 and 72, 6 associated with the timing wheel. The shaft 94 which carries the arm 92 is electrically connected .by means of Wire 102 with the coil 52 of the magnetic relay. The circuit through this relay is through wire 104, switch terminals 106 and 108' of a circuit breaker 110 and wire 112 leading to the neutral wire 5 of the three-wire current supply. Normally, the circuit breaker 110 is closed, the contacts 108 and 106 being connected as shown in Fig. 2. When the solenoid 38 is energized so as to move the stamping heads 32 to printing position as shown in Fig. 3, the core 40 is lifted. This' core carries a projection 114 which on its upward movenient strikes the circuit breaker 110 and separates the contacts 106 and 108 thus open- 'ing the circuit of the coil 52. This results in deenergizing said coil and permits the switch member 54 to drop, thus opening the circuit across'the contacts 56 and 58. This deenergizes the solenoid 38 whereupon the core descends.

In operation, assuming the parts to be in the position illustrated in Fig. 2 in which position the; contact arm 68 is electrically connected with contact 72, no circuit is applied through th cause wire 90 leads 0 the contacts 82 and 86 neither of which in this position are oppo-- the roller engages contact-74'. The shaft 66- of the measuring wheel is electrically connected by means of wire 116 with feed wire 0 of the supply circuit. As contact arm 68 engages contact 74, circuit from feed wire ,0 iscompleted through wire 88, contact 80 and rm in this position be-i arm 92 of the selector switch and 'wire 102 i 7 through the coil 52'of the relay and wire 104 through the then closed contacts .106

and 108 of the circuit breaker and wire 112 which leads'to the neutral wire b of the feed supply. Completiori of this circuit energizes coil 52, thus lifting the switch element 54 and closing the circuit across the contacts '56 and 58 thereby closing the cirstrikes the circuit breaker 110 and separates contacts 106-and 108 thus breaking the circult through the coil 52 and thereby. perlg g t e switch member 54 to 'drop. i 9,

This opens the circuit across contactsi 56 and 58 and deenergizes the solenoid. As

:the solenoid core 40 moved up the pawl 98- moved to the position of Fig. 3. Upon deenergization of the solenoid, the pawl will turn the ratchet 96 one-quarter of a revolution in counter-clockwise direction. This will move the contact arm 92 from the full line position to the dotted linefposition by wire 90. It is thus seen that upon each downward stroke of the solenoid core 40 the selector switch arm 92 is advanced one- 'quarter of a revolution andthe connections are such that the circuit through the electromagnetic relay coil 52 is alternately completed through wires 88 and 90. Thus it is seen that the function. of the selector. switch is at each stroke of the solenoid to select an alternative circuit to be energized when the arm 68 driven by the measuring wheel makes contact with that alternative circuit. p
