This invention relates to a machine for applying labels to rubber hose or cable or the like.

It is an object of this invention to provide an apparatus which will automatically apply a label to the hose, at spaced intervals, as it is fed through the machine.

It is a further object to provide apparatus of the character described Which operates simply and efficiently at the speed of movement of the hose, regardless of what the speed of the latter may be.

The invention accordingly comprises a device possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawings, in which:

Fig. 10 is a wiring diagram showing the electrical connections.

Fig. 11 is a section on the line XI-XI of Fig. 9 looking upwardly.

The numeral 20 comprises a base having at 2! a label applying mechanism and at 22 a guide and feed mechanism that is operated by movement of the hose through the device and which in turn causes the periodic operation of the label applying mechanism. The guide and feed mechanism (Fig. 3) comprises primarily a grooved roller 23 pivoted in upstanding brackets 24 upon the base 20. Mounted in slots 25 in the brackets 24 is a second grooved roller 26, the grooves in the rollers 23 and 25 being of a diameter to conform to the diameter of the hose 21 which is to be labeled. Spring 28 urge the shaft 29 of the 2 roller 26 downwardly so as to grip the hose between the rollers 23 and 26. Mounted about the roller 26 is a box 30 adapted to contain a soapstone or the like to give to the roller 26 a surface character which will not adhere to the hose 21.

The guide and feed mechanism just described is arranged to operate the contact device 3| at regular intervals which in turn operates the label applying mechanism. To accomplish this first result, a pulley 32 is mounted on the end of the shaft 33 of the grooved roller 23 which by means of a belt 34 drives a counter shaft 35 which by means of a belt 35 drives a shaft 3'! upon which the operating part of thecontact device 3! is mounted. In order to permit a variation in the spacing upon the hose between the labels, I prefer to provide at each end of the belt 36 a set of cone pulleys 38 and 39 in any pair of which the belt 36 may be placed.

The contact making device 35 itself is illustrated more fully in Fig. 8, in which it will be seen there is provided upon shaft 3'! a disc 40 of insulating materialcarrying a contact 4|, and mounted upon an insulated support 42 is a pair of terminals 43 spaced apart from each other concentrically about the shaft 31 in such position that the contact 4| may bridge between them once in each revolution. In order toprevent arcing when the contact is broken between the terminals 43 and the contact 41, there is provided around the contacts a casing 44 containing a body of oil 45 in which the terminals 43 are continuously immersed so that the contact is always broken under oil. The shape of the contact members 4| and 43 is not important so long as they are so arranged that the member 4| will swing past the members 43 and bridge across between them once during each revolution.

The label applying mechanism (see Figs. 3 and 4) includes a roller journaled on a shaft 5|, the roller 50 being substantially in alignment with the roller 23 previously described. This roller 53 is also grooved to the diameter of the hose 2'! and itself turns in a box 52 likewise containing powdered soapstone to prevent the hose from sticking to the wheel. Mounted beside the box 52 is a label magazine 53 arranged in a vertical position, containing a follower 54 (see Fig. 5) sliding upon guide rods 55 and urged upwardly by a spring 56.

At the top end of the magazine there is provided a head 51 supported by bolts 58 from a base 59 in which the guide rods 55 are also fastened. Above the head 51, there is supported a plate 59 which is attached to the head.

The opening 50 in the magazine 53 and in the head 51 is of the size and shape of the labels to be supplied, but the opening in the plate 59 is slightly smaller on the side away from the roller 50 and on both ends 50 as slightly to overlap the opening in the magazine itself, as shown at 6|, so that as the labels 62 are pressed upwardly by the spring 56, they are held by the plate 59 from being ejected. We have stated that the overlap occurs on three sides; on the fourth side, that is the side toward the roller 50, the plate 59 is cut away entirely so that the topmost label may he slid out from under the plate 59 laterally, or up and out from under the plate.

Mounted above the roller 50 and the label magazine 53 are a pair of bars 63 having their front ends at 65 sliding between the blocks 64 mounted upon an upright 66 carried from the base 20, as for example, by being mounted on the box 52.

The other end of the bars 63 are pivoted by a vertical pivot 61 mounted on a post 68 supported from the base 20 (see Figs. 1 and 2).

These bars carry horizontal tracks 69 on which is slidable a cross head I carrying the label transferring device.

This label transferring device comprises primarily a hollow head 12 carrying on its lower face a flat, curved or concaved suction plate I3 (see Figs. 4, and 6) of substantially the size and shape of the label to be affixed and having a plurality of holes I4 leading from the interior of the head to the lower face. A conduit I5 connects the interior of the head I4 with a valve I6 (see Fig. 1). The head I2 is carried by a vertically sliding member 11, slidable in vertical guide 18, mounted upon the crosshead Ill. The hollow head I2 is attached to the member TI by a screw I9, screwing into the head I2 at 80 and by a pin 9| extending downwardly from the member I1 into a recess in the head I2.

From Fig. 2 it will be clear that the crosshead I0 is slidable along the guides 69 from a position in registry with the label magazine to a position, as shown in dotted lines in Fig. 4 immediately above the hose 21, and back again.

The vertical position of the member I1 is determined by pins 92 carrying at their ends rollers 93 which run on a track surface 84 on the track 69. This track surface 94 is preferably provided at each end with a depressed portion 85 to cause the head to drop at each end of its stroke and to rise slightly before commencing movement in the guideway.

To eifect the reciprocation of the crosshead, there is mounted upon the base a vertical shaft 90 carrying at its upper end a circular plate 9|, upon which is eccentrically mounted a pin 92 serving as a pivot for a connecting rod 93, which is in turn connected by a pin 94 with the crosshead I0, so that the reciprocation of the crosshead occurs once for each revolution of the shaft 90.

The shaft 90 is driven by a motor 95 one terminal of which, as will be seen from Fig. 10, is connected at 96 with one side of the power mains, and the other terminal at 91 with one of the terminals 43 of the contact device 3|, the other terminal 43 of which is connected to the other power main at 90. Disc 9Ia upon the shaft 90 carries a circumferential cam 99 in position to engage an arm |00a of a contact making device I00b to make contact between the contacts I00 and IOI. This cam 99 is a circumferential strip extendin almost around the periphery of the disc 9| (1, so that the contact maker I00b will be operated just after the parts begin to move upon the closing of the contact 3|, and will keep the contact closed until one revolution has been almost completed and the core I03 is almost ready to enter into notch I04. Connected across the terminals 96 and 91, and thus in multiple with the motor 95 is a solenoid I02, the movable core I03 of which is in position to enter a notch I04 of a disc I05 on the same shaft with the plate 9|, and this core I03 is urged outwardly into the notch I04 by a spring I06. Thus the movable core serves to lock the shaft 90 against rotation.

The member 99 is so positioned relative to the notch I04 that the members I00 and IOI are out of contact at the time the core I03 rests in its notch, which is at the completion of the return stroke of the label applying head, that is while the head is in registry with the magazine. Mounted also upon the underside of plate 9| on shaft 90 is a cam I01 operating an arm I 09 which moves a plunger I09, forming the valve 16 which, when open, affords communication between the conduit I5 and a reduced pressure chamber H0, in which the vacuum is automatically maintained by a suitable exhaust pump I I I driven by a motor I IA which, subject to its automatic control, operates continuously while the device is in use.

The construction of member 99 is such that the contact is closed shortly after the motor starts to operate through the contact maker 3|, and the contact continues to be closed until a short time before the revolution is completed and the core I03 is ready to enter into the notch I04, the completion of this movement being accomplished by the momentum of the parts, The actual constmction of the operating mechanism of the valve I09 is best shown in Fig. 2, in which the cam I01 which operates arm I08 is mounted on the underface of the plate 9|, the valve being normally biased to closed position, but being held open while the cam I 01 holds the arm I08 against the action of its spring, The cam I01 is of such size and is so positioned that the Valve II is opened to apply suction immediately after the commencement of the movement of the shaft 9|, and to continue to apply that suction until the label has been taken from the label magazine and carried over to the position shown in dotted lines in Fig. 4, where it is immediately above the hose.

It will be understood that the hose is ordinarily fed to the machine immediately after fabrication while its surface is still sticky enough to adhere to the label. Otherwise, means will be required to supply an adhesive.

The operation of the machine will be obvious from the foregoing description. The hose or cable 21 is intended to be drawn through the machine either by an external mechanism which fabricates it, or by any other external means, and thus the hose or cable serves as the driving force for the machine operation. This is accomplished by the roller 24 itself driven by the cable, which in turn drives the contact maker 3| through the adjustable reduction gearing, thus closing the contact 3| once for every length of hose which passes through the machine, the exact length being determined by the adjustment of the reduction gearing. When the contact has been made, the label applying mechanism starts in operation by the motor starting rotation of the shaft 90. Thereafter the label is picked up and applied to the hose, whereupon the machine comes to rest, until the contact 3| is again closed by the movement of the hose.

This movement of the hose driving the wheel 23 operates the contact maker 3| after a predetermined length of hose has passed through the machine. When the contact maker 3| operates, it connects the circuit to the solenoid, Withdrawing the plunger 463 from the notch Hi4, permitting the shaft 95% to rotate. At the same time the contact maker starts the motor 35 in operation to drive this shaft. The contact maker 3| breaks contact thereafter, but before this occurs the circuit is closed through the parts we and NH so that the motor continues to operate under power for almost a complete revolution, whereupon the contacts Hill and IUI separate to open the circuit, permitting the momentum of the motor to continue the revolution as I have previously described.

During the early part of this revolution on the shaft 99, the valve "it admits suction to the hollow head 12 to grasp the topmost label, and immediately thereafter the connecting rod 93 moves the head, carrying the label to the label applying position as previously described. At this point. the suction is cut on and the label drops on to the hose, the surface of which is prepared to receive and adhere to it. The connecting rod 53 immediately returns the hollow head to the position above the label mechanism and the power is cut off from the motor 55, and the label affixing mechanism becomes idle until the next operation of the contact maker 3%, During this operation it will be noted that the label may be brought into contact with the hose before it is actuall released by the suction, if desired, without disturbing the place of the label upon the hose by reason of the pivoted action of the guides 63 about the pin 61.

Since certain changes may be made in the above construction and diiferent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
