Claims.

This invention relates to certain new and useful improvements in devices for marking articles and more particularly to a device for marking upon a moving package, coding or other identifying indicia during the movement of a package upon a traveling conveyor.

An object of the invention is the provision of a device having a simple and sturdy construction operable by a package to engage therewith active type characters of a type assembly of a type carriage for printing identifying coding or other indicia upon such package during movement thereof by a conveyor. By active type characters we mean such of the type characters as are disposed for engagement with the moving article.

A further and equally important object of our invention is the provision of a coding or package marking device having an arrangement for preventing overriding of the type carriage and for locating the type with respect to the package to be marked.

Another object of the invention is to provide a device for the purpose and of the character hereinafter described which may be used for printing indicia upon either the top, side, bottom, or end walls of a package under movement by a conveyor.

Another object of the invention is to provide an arrangement for aligning the type characters in the type carriage wheel.

An equally important object of the invention is to provide a device of this character wherein the printing mechanism is confined within an enclosure such as a hood or the like.

A further object of the invention is to provide a device of the character hereinafter described which comprises relatively few parts and one which may be economically manufactured and sold.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a fragmentary perspective view showing our improved package marking and coding device in applied position with respect to a package to be marked;

Fig. 2 is a perspective view of the same showing the hood thereof in open position;

Fig. 3 is a sectional detail view taken substantially on line 3-3 of Fig. 5 with the hood in closed position with respect to the typing mechanism;

Fig. 4 is a sectional detail view similar to that shown in Fig. 3 but showing the type carriage in position to engage a package;

Fig. 5 is a sectional detail view taken substantially on line 5-5 of Fig. 3;

Fig. 6 is a sectional detail view of the type carriage wheel taken substantially on line 6-6 of Fig. 5;

Fig. '7 is a fragmentary sectional detail view of the same taken on line 1--1 of Fig. 6; and

Fig. 8 is an elevational view of one of the type holding disks embodied in the invention.

The several objects of our invention are accomplished by the preferred form of construction shown in the accompanying drawings and in which our package marking or coding device is indicated at I0.

In Fig. 1, we have illustrated the device in its relationship to packages II to be marked or coded. These packages I l are mounted for movement in a horizontal plane upon a traveling conveyor l2. The marking and coding device I!) is supported in a proper position with respect to the packages I I by a supporting bar l3 which may be attached to a frame structure (not shown) of the conveyor [2. This supporting bar [3 has a horizontally extending arm [4 to which is pivotally connected a hood l5.

A main carriage is indicated generally at It. This main carriage supports the type or printing mechanism to be presently described. The main carriage comprises similarly constructed side plates I! and I8 arranged in parallel spaced confronting relation with respect to each other and providing at corresponding end portions bearings l 9 through which the arm [4 is journaled thereby to pivotally support the main carriage from the bar l3.

The opposite corresponding end portions of the plates l1 and l 3 provide upwardly extending arms 20 connected together by a tie bar 2|. This tie bar 2| cooperates with a spring latch 2| carried by the hood [5 to latch the hood in covering position with respect to the carriage [6. The carriage I6 is yieldably urged in a downward direction with respect to the arm M by means of a spring 22 embracing the arm I4 between the plates I1 and I8 having one end portion 23 hooked to a shaft 24' the latter serving to connect the adjacent end portions of the plates I 1 and I8 together. The opposite end portion of the spring frictionally projects into a socket 24 provided by a collar 25 fixed to the arm I4 by a suitable set screw 26.

At the junction between the plates l1 and I8 and the arms there are provided transversely extending elongated slots 21 in which are journaled the end portions 23 of a shaft 29. These end portions 28 of the shaft 29 are threaded to receive the retaining nuts 30. On this shaft is rotatably mounted a type carriage wheel indicated generally at 3|. This type carriage wheel 3| comprises similarly constructed circular side discs 32 spaced from each other by a suitable spacer sleeve 33 and having their circumferential edges knurled as at 34 to provide gripping surfaces which surfaces when engaging the package II will effect rotation of the type carriage 3| about the shaft 2 9.

These discs 32 are connected in spaced relation with respect to each other by spaced plates 35 having upstanding flanges 35 secured to the discs 32 by nut receiving bolts 31.

The type carriage wheel 3| is shown as supporting two sets of type assemblies 38 and 39; however, the arrangement may be such as to carry more than two assemblies. Each of the type assemblies comprises a shaft 40 carried by the spacer plates 35 and fixed to such plates by means of nuts 4| threaded upon the threaded end portions 42 of the shaft 40. Mounted on the shaft are type character wheels 45 each comprising confronting discs 43 having inwardly turned flanges 44 engaging in grooves 45 formed in type shoes 45. These type shoes 46 support the type character 4'! and are adjustable circumferentially with respect to the discs 43. The discs 43 are spaced from each other by a spacer sleeve 48.

The shaft 45 in cross section is substantially rectangular and each of the discs has similarly shaped openings formed therein. The type characters 38 may be formed of any approved material. In order to present the type upon an arch corresponding to the circumference of the discs 32 the openings 4| of the discs of the intermediate type wheels are slightly off center with respect to each other as shown in Fig. 8 to present the type character upon such arch.

The type characters, which we term the active type characters, are properly aligned for the printing operation by means of an aligning plate 49, there being one such aligning plate for each type assembly. Each aligning plate 49 comprises an elongated slot 50 through which the active type characters project. The aligning plate provides inwardly turned end portion 5| providing sleeve 52 through which projects a stud shaft 53 for pivotally connecting the aligning plate 49 to the discs 32.

The spacer plates 35 each carry a spring latch 54 which bears against the inwardly turned portion 5| of the aligning plate to yieldably hold such plate in position with respect to the active type characters.

In order to time the engagement of the active type characters with respect to the package to be printed upon by such type characters we provide a combination anti-override and locating bar 55. This bar 55 provides at one end portion a bearing sleeve 55 through which is journaled the shaft of a connecting bolt 5'! by which the bar 55 is pivotally connected to an arm 58 adjustably fixed as at 59 to the arm M. A laterally extending stud screw 55 is carried by the side plate Hi and bears upon the bar 55 whereby to yieldably bear the bar 55 against lateral rollers 5| carried by pivot bolts 62 threaded into a plate 63. By means of slot and bolt connections 54 this plate 63 may be adjusted circumferentially 4 with respect to the shaft 29 to position the rollers for proper engagement with the locating bar 55.

By this arrangement the bar 55 in cooperation with the rollers 6| prevents override of the type carriage 3| as the disc 32 moves from engagement with one package to a trailing package. It also effects proper engagement of the active type projecting through the elongated slot 50 of the retaining plate 49 with respect to the package, whereby, as the package is moved beneath the type carriage 3|, the active type will at the proper time engage the surface of the package to be printed upon, thereby to make a complete printing or marking upon the package.

The inking mechanism comprises an inking roller 65 having a cylindrical ink absorbing pad 56 communicating with a reservoir within the roller 65, the ink being admitted to the reservoir through normally closed nipples 51.

This inking roller is rotatably carried by a shaft 58 fixed to an arm link 59. This arm link 69 is by means of bolt and slot connections 10 adjustably connected to an arm link The arm link H provides a bearing 12 through which is journaled the shaft 24, the ends of which are journaled through openings formed in the plates I! and I8. Embracing this shaft24 is a spring 73 one end of which is hooked as at 14 to the arm link II and the opposite end frictionally projected into a socket 15 formed in an adjustment nut 15 mounted on the shaft 24 and having a plurality of notches H which are adapted to selectively receive the end portions of a pin 18 carried by the shaft 24 whereby the spring I3 r may be placed under the desired tension.

The arm link II rests on an eccentrically mounted stud 19 carried as at by a plate By adjusting this eccentric stud 19, the downward pivotal movement of the arm link H may be varied. By adjusting the arm link 59 relative to the arm link ii, the position of the inking roller upon the type carriage 3| may be adjusted for the best results.

In use the supporting bar |3 is supported from a frame element of the conveyor |2 to support the carriage it in the path of movement of the packages II. By adjusting the arm 58- relative to the arm M the distance between the type carriage 3| and the elevator may be varied to compensate for boxes of various heights. By adjusting the collar 25 relative to the arm M the bearing pressure of the locating bar 55 upon the rollers 6| may also be varied to the proper degree which permits a proper rotation of the type carriage 3| by the moving package ll. Likewise, by adjusting the nut "it relative to the shaft 24 the proper tension will be exerted upon the inking roller as will best serve the purpose.

During the operation of the device the hood normally encloses the main carriage l6 as well as the upper portion of the type carriage 3|. A package or other article moving beneath the type carriage 3| by the conveyor |2 will engage the knurled edges of the type carriage discs 3| and 32 and impart rotation to the typecarriage 3| whereupon the active type characters will be brought into printing engagement with respect to the surface of the package on which the indicia or other characters are to be printed. During this rotation of the type carriage 3| by movement of the package on the conveyor |-2 the rotation of the type carriage 3| is yieldably restrained by the override and locating bar 55. By this arrangement, the active type will properly engage the surface of the box on which the printing is to be made.

By constructing the type carriage 3| in the manner herein described, adjustment of the type character may be made by merely moving the type retainer plate 49 from engagement with the active type and then shifting the type characters circumferentially with respect to their respective wheels to bring the desired type characters into position for passage into the slot 50 of the retaining plate 49. This plate not only retains the type characters in position but also effects alignment of the type characters with respect to each other.

When the device is not in use, the hood l5 may be pivoted to an open position as shown in Fig. 2, and the ink roller elevated from the position shown in Fig. 2, in which position the ink roller may remain until it is desirable to again operate the device.

For the best operation it is desirable that the adjustment between the locating bar 55 and the rollers 6| be such that during idleness of the type carriage 3| the inking roller will not be disposed on the active type character projecting through the slot 50. By such an arrangement impressions are not likely to be formed in the inking pad of the roller which would otherwise result were the inking roller left to remain in engagement with the active type.

As before stated, our device may be used for the purpose of marking upon the side walls as well as the top walls of the box. This may be accomplished by supporting the device from the conveyor, so that the type carriage 3| will engage the adjacent side walls of a box.

The simplicity of construction of our device permits the same to be manufactured at an economical cost. The device may be used for marking upon boxes of various sizes, the construction affording the type carriage to be adjusted to accomplish that purpose.

While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to protect by Letters Patent is:
