1 tion or are adjustable to operate markercari 'yin-g members suchas disks .onvvheels For many of the purposesfor which such machines are employed, it is necessary or desirable to adjust the markers very frequently illla order to printdifferent characters or combinations of characters; 011 the other hand, the markers mustibe: held frictionally or positively against displacement from adjusted positions at least duringoperations of the machine. It is important, therefore, that adequate provision bemade for 'releasing. themarkers and for setting:v them to impress any desired character or combiua tion of-charact'ers.

In view: of the foregoing, it'is an object of thisinvention to provide a marking ma chine having simple and efi'cctive devices for releasing markers and for relatively-adjusting them as desired; To this end, the illustrated machine is provided with setting devices adapted toloe connected:selectively to locking deviceswhich operate normally to restrain the markers. froml movement out i of adjusted position and to release the looking device or lockingqdeviccs: of the marker 01' markers which it is desired to adjust uponinovement ofthe setting device or devices. In the illustratedorganization, the markers are carried by a series of rotatable disks normally restrained by latches and adapted to be turned by star Wheelstobring. various markers or combinations markers'into operative position upon releasing the appropriate latcl'ies,.the connection between'the setting devices, that is ,..the star wheels, and the latches to release the latchesbeing ef fcctcd by shifting a sw inging frame which carricsthe star Wheelsand is adapted in one positionto release one or more of the latches. p

' The illustrated constructionand arrange menthave the advantage, among others, that tlrc (,iperator may, by using one hand only; imlocl: the desired marker or markers and olt'ect the desired relative adjustment of'the markers. "Moreover, it'will be apparent that this organization is equally applicable to marking machines of the type above referred to in which thesetting devices, insteadof operatingdirectly 011 marker-carryingdisks orother members, effect the rela live adjustment of they marker-carrying members through intermediate disks or other devices. I

1 These and other features of theinvention will be more readily understood froma considoration of. the following specification taken in connection withthe accompanying drawings in which: Fig. l is a sidcelevation of one form of marking machine to which a marking head provided with my improved setting device has beeniapplied;

Fig; 2 is a transverse vertical section through the marking head; and v Y r Fig, 3 is a fragmentary perspective showing a single rotatable disk and the associated latch and setting device. i 4 In the machineto which my invention has been,illustratively applied an automatically adjustable work-supporting table 10 is slidablv mounted in a guide 12 formed in a bracket attached. to a frame 14 of the machine; A locking" arm 16 holds the table against vertical movement when the machine is atrest. The marking mechanism is carried for up-and-down movement ina sup port ZOcomprisinp: laterally spaced hangers and 2% which are pivoted at 26 upon a bifurcated bell crank lever. 28 to which power may be supplied. to move the marking head into engagement with and away from the work. The support 20' is guidedfor movement in parallel planes by means of a parallel arm 30 pivoted in the machine frame at 32 andjpivotally attached to the upper endof the support 2( at 34. An inking roll 36 is arrangedvto carry ink from an inkingsupplyroll 38 lJOfllle type faces and this inking roll is carried on the end of an arm 40 pivotally mounted in the frame of the machine and actuated by a link 4-2 from an extension 14 on the parallel arm 30. vA rod 16 connected to the bell crank lever 28 passes through the end of the table-locking arm 16 which is normally held in looking position by means of a spring 18 surrounding the rod 16. As the head is carried into marking position, however, the enlarged end 50 of the rod 46 raises the table-locking arm 16 and allows automatic adjustment of the table under the tension of a spring 52 and the pressure of the marking head upon the work 5' carried by the table so that said pressure is uniform regardless of the numbers of layers of work carried thereby. I

As-best shown in Figs. 2 and 3, a tube 60 is carried between the lower ends of the hangers 22 and 2 1 and provides a support for a plurality of adjustable markers in the form of rotatable disks 62 which in the particular instance are notched disks, as shown in Fig. 3, provided with type faces upon the projecting teeth of the disks. Retaining latches for each of the disks 62. such as the latch 64 in Fig. 3, are pivotally mounted upon a rod 66 extending between the hangers 22 and 24 and are resiliently biased into engagement with the notches of the disks by springs 68 (Fig. 1). Each of these latches is provided with an upward projection 70 shaped like a miniature gear tooth for a purpose to be later explained.

A swinging frame made up of side menr bers 72 and 7a (Fig. 2) joined by a rod 76 is pivotally mounted upon the outer ends of the tube 60 so that it may be swung through a limited are determined by the engagement of the rod 76 with notches 78 (Fig. 3) provided in the hangers 22 and 24 of the marking head support. One or more spring plungers 80 (Fig. 1) are arranged to bias the swinging frame to its rear limiting position. A setting device mounted for rotative setting movement and lateral selecting movement in the swinging frame is provided with star wheels 82 and 84 (Figs. 2 and 3) shaped for engagement in the notches of the rotatable disks 62 to rotate said disks when brought into co-operative relation therewith by lateral movement in the swinging frame. The star wheel 82 is secured to a rod 86 passing through the swinging frame and provided with an operating wheel 88 while the other star wheel 84 is mounted upon a sleeve 90 surrounding a reduced outer end 92 of the rod 86 and the sleeve 90 is provided with an operating wheel 94. The rod 86 and the sleeve 90 are provided with a succession of grooves for engagement by suitable plunger latches 96 and 98 to make it easy for the operator to bring the star wheels into the desired lateral position so that they will accurately engage each with a single disk 62. Latch-releasing devices 100 and 102 are pivotally mounted upon the rod 86 and the sleeve 90 respectively and are held against the star wheels 82 and 8 1 by means of collars, as shown in the drawings. The upper end of each of these latch-releasing devices is notched forengagement with the rod 7 6 to prevent rotation of said devices when the star wheels are rotated. A notched rearward extension 10st is provided upon the latch-releasing device 100 and is bent at its outer end into the plane of the star wheel 82 so that it will engage with the projection 70 upon the corresponding latch 64. A similar extension (not shown) uponflthe latch-releasing device 102 is bent laterally in the opposite direction to bring it into, the plane of the star wheel 84 so that it will engage the projection upon the retaining latch which corresponds to the disk with which that star wheel is in co-operative relation. Swinging movement of the frame carrying the setting device and the latchreleasing members will therefore raise the latches out of engagement with the corresponding disks byreason of the fact that said latches are pivoted upon a rod in the hangers while the swinging frame carrying the latch-releasing members is movable relatively to said hangers.

If desired, a nameplate 110 may be used in connection with the marking head and releasably held with its printing face in the same plane with the printing face of the particular row of characters which is to be used. This name plate will be held in posi tion by a finger latch 112 (Fig. 1) or may be removed from the marking head by releasing said latch.

In setting the markers upon the marking head the operator, grasping one or the other of the handles 88 and 94:, will bring the star wheels of the setting device into engagement with the disks which it isdesired to rotate, and then bias the swinging frame to its forward position so that the latchreleasing devices will, by reason of the relative movement of the swinging frame and the head, lift the corresponding latches out of engagement with the rotatable disks. The operator is then free to set the corresponding disks by rotating the operating handles 88 and 94. After the desired characters have been brought into printing position the release of the setting device allows the swinging frame to be biased to its rear position and thereby allows the corresponding latches to drop into engagement with the disks which have been set, to hold them in adjusted position. It will be understood that, in the use of such a machine for shoe work as above mentioned. the disks carrying the size and half size characters are those which will need to be changed most frequently and in such use the setting star wheels will normally be left? in position for engagement with said disks: It then becomes necessary in setting-a size disk, for example, for: the operator to-grasp the corresponding handle 88er- 94; pull forward the swinging frame to release the latch, rotate the disk, let'- go of the handle and allow the latch to be swung hack into operative position: lVhen it= is=desiied to rotate the 1 other disks, the setting'device may be moved iangedi to transfer movement from the set ting device to the disks or corresponding members which do carry the printingtypes.
