MARKING .MACHINE Application filed May l5, 1922.

Be it known that I, DnNYs Viv. liionnnr, a subject oi the King ot lllng'land, residing at Leicester, Leicestershire, lilngland, have invented certain improvements in Marking' Machines, oit' which the following description, in connection with the accompanyin1 drawings, is a specification, like reifer-ence characters on the drawings indicating like parts in the several figures.

This invention relates to marking niachines and is herein shown as embodied in a machine tor marking articles by the application ot ii'ietalileaif.

A machine which has been commonly used igor marking` shoe uppers and the like with identifying numbers or other symbols comprises a type head having' a series of type wheels mounted on an oscillatinng` arm which carries the type into contact with the work. ytometimes an additional line of printing is turnished by a so-calletl stock vplate attached to the type head, either in front of,

or behind the line of printing furnished the type wheels. It is an object oi this ininvention to provide a machine of this character in which the marking medium can be applied economically to the impression members from a cont-inuous strip of material, Such a mark is more ornamental than ink and is in considerab'le demand 'for embossing' the top stays or shoes or the like. This embossing; lea't comes in the form of a metallic powder applied unit'ormly to a backing' of lilmsy paper. This material is expensive and the strip is easily torn but, if the diiiiculties encountered in the handling of the delicate material can be overcome, it is preferable to pastes and suspensions oi4I the metallic marking;` material which, in use, are apt to change in character and consistency.

As one feature of the invention the strip of marking material. is ted intermittently in the directon of its length beneath the type wheels, and there is also provision `for giving the strip a lateral feed so that the entire width of the strip can be utilized without any waste. In the construction shown, a carriage is mounted to slide under the marki'nghead and carries at one side of the head a supply reel for the marking medium and Vat the other side a feed roll. The carriage and roll are so actuated that the markingmaterial is fed longitudinally after every Serial N0. 561,094.

second impression, there being a lateral feed between each two impressions so that first one halt' the strip is used and then the other half. By this sort of t'eed, a wider marking;` strip can be used and consequently oneot greater strength. is a Yfurther feature, the mechanism is so arranged that, where there are two lines ot' printing, the lateral feed oi? the strip can be eliminated and its iull width utilized at every impression. l4`iiitlie1iiioie, since the additional line of printing may be either in i'ront oi' or behind the type on the type wheel, the carriage can be arranged in a suitable position for either condition without interfering with a longitudinal feed of the strip after each impression. e

These and other features and advantages of the invention will appear from a consideration ot the following si'iecitication and accompininyin .e` drawings, in which- Figure l. is a left-hand side elevation withsome parts broken away and in section;

Fig. 2 a iront elevation with some parts removed;

Fig. fl is a section on the line elf- 4; ot Fig'. l;

Fig. 5 is a section on the line 5 5 ot Fig, 2; and

Figs. G and 7 are details oit' the scraping mechanism for one of the rollers.

The work is presented on a work support 6 which underlies a type head 5l comprising a series of type wheels mounted to turn about a horizontal axis, the hubs ot' the wheels being provided with an opening,` l() for the reception ot' a heating unit. rThe type head is carried in a vibrating,` arm l2 which rocks about a shaft 11i on the frame of the machine. dit the sides ot the vibrating' arm l2 are `grooves or ,euideways .i6 arranged` to support, 'for slidingT movement. a carriage 1S which has tongues entering; the grooves 16. The carriage 1S carries a supply reel and the feeding mechanism for the stamping` medium. As shown in Fig. 2. there extends from the right hand side ot' the carriage a bracket arm 20, on the end oit which is support-ed a'supply reel 22, preferably held against too free rotation by a tension device. The markii'ig'niedium is in the form of a strip 2% which passes from the supply reel 22 under ta roller 26, then below the type wheels and around the feed roller 28 between said roller 28 and a pres sure roller 80. All of these r-o-llers are made of some material which will not conduct heat, such as compressed asbestos fibre, so that the portions of the strip not directly acted upon are protected from the heat of the head. Any other suitable material can be used. The pressure roller 30 is carried in an arm 32, which hangs downwardly from a stud shaft 34 fixed on the carriage 18, the arm and roller being pressed towards the feed roller by a coiled spring 36 surrounding the stud shaft.

The feed roller 28 is sup-ported for intermittent rotation in the following manne-r: A stud 40 is fixedly secured in a bracket on the carriage 18 and supports for rotation a bushing 42 having at one en d a toothed member 44, keyed by means of the pin 46 to the feed roller 28. lithin a hollow extension o the feed roller,there extends a second toothed member 48 fixed on the end of a slide rod 50 arranged for limited endwise movement on the oscillating arm 12. The rod 50 is provided with a helical slot 52 into which extends a pin on a block 54 which slides in a guideway 56 on the oscillating arm. The inner end of the slide rod 50 is reduced in size and is provided with stop collars 58 and 60 which limit its movement by engagement with an adjusting sleeve 62 surroundingan extension 64 from the arm 12. The adjusting sleeve 62 carries a pin arranged. to engage selectively in openings 68 and 70 of the extension, said pin being pressed up wardly into one of the openings by a spring 72 and being withdrawn by the aid of the cap piece 74. As will herein; fter appear, the purpose of this adjustment to set the slide rod in such an initial position that a feed of the strip will take place when the carriage is fixed in either its forward or rearward position for two-line marking.

The means for rotatingthe feed roller and sliding the carriage will now be described. The block 54 receives a reciprocating move ment through a link 7 6 pivoted at one end to the block and at the other end to a slotted arm 7 8 on a hub which is rockable on the shaft 14, a thumb screw being provided to adjust the pivot in the slot and thereby control the throw of the link. The hub is rocked on the shaft14 by an arm. 82 which may be connected in any suitable way to the drive shaft of the machine. A third arm 84 on the rockable hub has a connection through a link86 with an arm 88 which rocks loosely on a shaft 90 extending across the vibrating arm 12. The arm 88 carries a pawl 92 which is pressed by means of the spring 94 against awratchet on the shaft 90 and arranged to cause the intermittent rotation of a pair of cams 96 also fixed on the shaft at the ends thereof.

wheel 95 yfixed f rlhe cams 96 cause the lateral movement of the carriage and are provided., in the illustrated construction, with high parts 98 arranged 90o apart, each high part being followed by a depressed portion 100 which is concentric with the shaft 90 and this portion being followed by an incline 102 extending out to the next high part of the cam. Extensions 104 of the carriage 18 carry at their ends rollers 106 riding on the peripheries of the two cams, a spring 108 holding the roller against the cams and serving to retract the carriage whenever the cams are rotated to allow this action. As shown in Figs. 6 and the pressure roller 30 is provided with a plurality of grooves 110 while a bar 112 extending parallel to the roller has a corresponding series of scrapers 114 extending into the grooves and constructed to prevent the strip of marking medium from adhering to said roller.

Assuming that the parts are arranged as shown in Fig. 1, with the carriage in its forward posit-ion, and that an impression has just been made upon the rearward half of the strip, oscillation of the arm 88 during the next vibrating movement of the head causes the intermittent rotation of the cams 96 in a clockwise direction, 1. As soon as the rollers 106 ride ofi1 of the high parts 98 of the cams, the carriage 18 is moved to its rearmost position by the spring 108. Meanwhile the block 54 is moved forwardly, first causing an endwise movement of the slide rod 50 to an extent permitted by the lost motion between the sleeve 62 and the stop collar 58, this action carrying the toovhed member 48 into engagement with the corresponding toothed member 44 on the feed roller 28. Thereafter, the forward movement of the block 54, by reason of its connection with the helical groove 52, imparts a rotation to the rod 50 and, therefore, to the feed roller. This action draws a fresh supply of stamping mcdium from the supply reel 22. rlhe next time that the marking head descends upon the work the impression is made against thc forward half of the marking strip. Upon the reverse movement of the oscillating arm 88, the pawl 92 rides over the ratchet 95, to secure a new grip for the subsequent operation and the block 54. in its reverse movement, first moves the slide rod 50 to disengage the clutch members and thereafter .rotates the rod idly. The cam rollers 106 now lie upon the concentric portions 1.02 of the two cam ends, as the cams are again given their intermittent rotation, the inclines 102 feed the carriage forward again. This forward movement of the carriage withdraws thetoothed member 44 out of engagement with its corresponding toothed member 48 so that. as the block 54 is again moved forward, the rotation of the rod 50 will cause as viewed in Fig.

no rotation of the feed roller and hence no longitudinal feed of the stamping st 1ip. In this position. the next marking operation takes place against the roar half of the strip. Itis apliiarent that by the above described construction the forward half of the ribbon is first impressed on the work, then there a lateral fe so that the rear half of the ribbon can be utilized, and then there is both a longitudinal feed of the ribbon and a lateral feed -again to bring the forward half of theI ribbon into working position.

iihenever the machine is used with the so-called stock plate to furnish a second line of printing characters behind the characters on the type wheels, the lateral feed mechanism is put out of action by removing the pawl 92 from engagement with its ratchet. The cams are then hired in a position such that the carriage 1S is retained in its rearward position, thereby bringing the toothed membes into approximate contact. Under these conditions, every forward movement of the block 5ft. causes engagen'ient of the toothed members and, therefore, a` feedmovement of the strip takes place after every impression. If the stock plate with the second line of printing lies in front of the type wheels, the cams Skare fixed in such a position that the carriage is retained in its forward position as shown in Fig. l. Then the adjusting sleeve 62 is moved forwardly until the pin G6 engafz'es in the opening 70. In this position of the parts, the two toothed members can be brought into engagement upon the forward movement of the block and a feed movement takes place after every impression as before.

Although the invention has been described by reference to a specific machine, it should be understood that the invention is not necessarily limited thereto.
