' This invention relates to marking inachines and more particularly to marking machinesdesigned to print a row of characters and arranged so that the markers may be rapidly interchanged between printing operk 4 Y I head and the setting mecl1anism;'and

ations; V x

The use of marking machines is common factories for manufacturing boots and shoes and in many other places for imprinting a row of characters upon a plurality of and when a marking machine is employed for such a purpose it is essential, for satisfactory use of the machine, that the operator shall'b'e able quickly and accurately to interchange the markers" upon the marking head without danger o't'soiling the handsor, in case the printing characters are heated, of burning the fingers. An object of the presentinvention is to provide a marking machine having an improved mechanism for setting the printing elements which will be arranged so that the operator may make the desired changes rapidly and accurately without encountering any of the difiiculties above mentioned. I

With this object in View, a feature of the invention relates to a novel setting device which may be brought into engagement with any one of a plural ity of adjustable markers. As illustrated, the markers are disks and displaceable retaining latches are provided for each of the disks and the setting device is so interconnected with the retaining latches that a ltlliCllflVlllCl] has been displaced to release one of the disks acts as a stop tor the setting mechanism to indicate to the operator that the setting device 1s in co-operative relation with the particular disk which has been released The illustratedsetting device is mounted for movement withln. the hubs of the various disks and is provided withta v rod mounted for movement outside thedisks in a path which intersects any latchwhich has been displaced.

These and other features of the invention as'point ed out in the appendedelaimswill be best understood from a consideration of the following specification taken in connection with the accompanying drawings in which a v Figl'l is a side elevation of the machine \vith'part s broken away; Y

the driving pulley The connection between comprises a latch 38 pivoted upon the marking head in printing position;

- Fig. '3 'is'a f'ont elevation of'the machine with parts broken away;

Fig. 5 is a vertical section through the .marking head and the setting device.

The frame 10 0f the machinecomprises end nembers 12' and 14; between] which" power shaft 16 and a crank shaft 18 aresup ported. Power may besupplied to the inachine in any desired manner but as herein illustrated it will be used to r'otatea belt pulley 20 floosely mounted'upon the shaft '16 and adapted to be clutchedtosaid shaft by a friction disk 22. A pinion 2&(Fig. 3) upon the power shaft 16 meshes with a gear 26 on' 'th'e' crank shaft- 18 and supplies power to rotate the latter whe'n the clutch is closed.

It'is desired that the clutch shall be so arranged that the crank shaft 18 will make one or more complete revolutions and then stop,

and to thisend a cam 30 is mounted upon the crank shaft 18 which acts against av lever 32 pivotally mounted'upon a transverse rod 33 andhe'ld against the camby aspring 35 to move a bifurcated lever 34: al'so'mounted on saidrod and at the desired time, pull the clutch disk 22 out of engagement with 20 against a tension spring 3 6 1nounted upon the power shaft 16.

the levers 32 and 34 is not a' fixed connection however, and it lever 32"andresili'ently held against a stop screw 40 by a spring ll. This latch 38 engages the notch of a" horizontal rod 42 pivotally connected at one en'd to the bifurcated lever 34: and at, the other end to a treadl e rod 44:.

This places the mechanism in such condition that an'upward niovement ofthe trea dle rod lt under the control of the operative releases the horizontal rod 42 and allows the spring 36 t'o throw the clutcliinto operative engagemerit with the driv in'g pulley '20; thereby supplying power to the crank shaft 18 and eiiecti'ng rotation of the latterl Assoon as the treadle rod 44 is released the operator the will a'gain slip intdposition for engagement-with the notch" in the horizontal rod 42 so that the cam 30, aeting throughthe lever 32and'the now connectedle v'er 34, will Fig. 2 is a fragmentary view showing the become effective to throw out the clutch at the completion of a full revolution of the crank shaft 18.

The marking head is supported in a hanger 50 which is pivotally mounted upon the outer end of parallel links 52 and 54; which are pivoted within the frame of the machine, so that the hanger 50 is maintained in substantially vertical position as it is moved up and down to bring the printing characters into and out of engagement with the work. The link 541 is extended to the rear, as shown in Fig. 1, where it; is connected by means of a link 56 with a crank 58 on the crank shaft 18.

The marking head comprises adjustable markers for printing characters, which will be described more in detail and ink is supplied to said markers bynieans of an inking device comprising a rotatable cylinder 60 mounted upon the frame of the machine and adapted to be kept coated with ink from a reservoir 62 placed over the rear upper quadrant of the supply cylinder 60 in a position where it may conveniently be filled as desired and, by virtue of a scraper plate ca adjustable by means of a screw 66, may be caused to supply a film of marking material to the rotatable cylinder 60. To transfer the ink from this cylinder to the markers a transferring roll is carried upon the outer end of an arm 7 2 pivoted at its upper end in the frame of the machine and actuated by means of a link 7 1 which is connected to an extension 76 upon the upper parallel link 52 so that it is brought into position to wipe across the markers as the marking head moves into inoperative position and to wipe across the supply cylinder 60 as the marking head moves into printing position, as'shown in Fig. 2. It will be noted that the transferring roll is carried upon a pivoted extension 7 8 ofthe arm 7 2 which is spring pressed upwardly by a spring 80 to hold it resiliently in engagement with either the markers or the'supply roll as the transferring roll 70 is caused to wipe across first one and then the other.

It is frequently desired to use a machine of this type for marking a stack of similar pieces of work, as indicated in Figs. 2 and a, and to facilitate the use of the machine for such an operation a work table 82 is provided having a post 8 1 slidably mounted in a suitable bearing 86 formed at the outer end of a bracket 88 on the frame of the machine. Interposed between this bearing and the work table is a spring 90 the tension of which may be adjusted by means of a screw 92 and the range of movement of the table with respect to the bearing sleeve is limited by the engagement of a stopscrew 9 1 in the sleeve with a slot 96 in the post'8 1. A.

holding latch 98 is then provided which has a locking cam positioned for engagement with the side of the post 84 to hold it in adjusted position when said latch 98 is pressed downwardly and to release the table for upward movement under the tension of the spring 90 when the latch 98 is moved to upward position. Mechanism is then provided for automatically controlling the latch 98 so that the table is released for automatic positioning by means of the combined action of the marking head on the stack of'work and the tension of the spring 90 with the result that the pressure of the marking head upon the work is kept uniform regardless of the number of pieces of work underneath the marking head. This allows the operator to hold the work in the manner indicated in Fig. 2 and to allow one piece after another to drop into position forengagement by the marking head without fear of producing an excessive pressure of the marking head when stack of pieces has accumulated. The au tomatic mechanism controlling the latch 98 includes a rod 100 pivotally mounted at 102 upon an extension 101'- of the parallel link 51 and slidably engaged at 106 with the outer end of the controlling latch 98. A head 108 is provided upon the rod 100 to lift the latch to release the post 8% of the table when the rod 100 has moved to upward position accompanying a downward movement of the marking head. When the marking head has moved to inoperative position, however, the rod 100 is moved to the position indicated in Fig. 1 and thereby tensions a spring 110 surrounding said rod and interposed between the controlling latch 98 and a stop 112 on the rod. This causes the controlling latch 98 to bite against the post 84 of the table and hold it againstvthe tension of the spring 90.

The arrangement of the marking head is best shown in Figs. 3, 1 and 5 from which it will be seen that the lower 'end of the hanger 50 is bifurcated to provide vertical arms 11 1 and 116 and a hollow supporting member 118 is mounted upon the arm 116' by screws entering a flange 120 in said hollow support. Surrounding this hollow support and rotatable with respect to it is a slotted sleeve 122 having oppositely positioned slots of which parts are filled by the rods 124: and 126 of the setting device. A plurality of adjustable markers are provided in the form of disks 130 rotatably mounted upon the slotted sleeve 122 and in the illustrated embodiment these disks are provided with teeth upon their external peripheries carrying printing type-faces. It should be noted that the setting device to be described is not limited in use to an arrangement in which the type-faces areplaced directly upon the disks with which the setting device is associated but may also be used with an arrangement (not shown) having a plurality of series of disks interis desiredto-change the position.

engagedwith one another so that the. typetaces are carried upon one of the ser es which is remote from the particular series adjusted by the setting device. These disks 130 are notched upon their inner peripheries as indicated in Fig. 5 so that there is a. notch corresponding to each, of the teeth upon the outer periphery. Vi hen in printing position (by which is meant-an alined position ready to print) the notches or the various disks will be alined to form the grooves which appear in Fig. 5. This arrangement enables the rod 126 of theset ting device to be provided with a tooth 132 ging the notches upon the inner peripheri s of the disks and is slidable transversely of said disks to-bring' it into, co-operat-ive relation with any particular disk of which it Preferably, the positionot the various disks upon the support is determined by means of displaceable pivoted retaitning latches' 134 which maybe of any convenient construction and preferably are arranged substantially as shown in U. S. Letters Patent No. 984,588, granted February 21, 1911 on the application of F. V. Merrick. It desired for the particular use to which the. machine put, a size lever 136 (Fig. 3) may be providcd which is arranged according to the principle described in said patent so that its operation causes the size wheels to be changed step by step to indicate a series of sizes and half sizes. The rods 124 and 126 are mounted upon a head 140 (Fig. 5) to which thereis connected a setting wheel 142 and bracket 144 is pivotally mountedupon this head and held rigidly against movement along the axis of the disks. This bracket 144 carries a rod 146 passing through a bearing 148 (Fig. 4) in the arm 114 and moving in a path intersecting the position of the retaining latches, 134 when any one of them has been displaced to release the corresponding disk' It should be noted from F 5 that the length of: the rod 146 is such that itwill engage the side of the retaming latch corresponding to the particular disk-with which the tooth 132 of the setting rod 126 is positioned in engagement.

"When the operator desires to adjust the markers upon the marking head, he will depress'a particular latch 134 corresponding to the disk whose position it is desired to change. The setting device may then be inoved laterally until the rod 146 contacts with the particular latch which has beendisplaced. This positioning movement of the setting device willbring the tooth l32 upon the rod126 in engage nentwiththe notch on the. inner. periphery of the particular disk which has been released by the displacement then be rotated by' turning the wheel 142 after which the operator will allow-the latch the disks are held 'tained in position by means of a members ity is particular markerv with which. the displace- -ablememberisassociated.

If it is desired to heat thedisks of the marking head an electric cartridge unit 150 may be inserted within the hollow support 118 thereby tosupply heat to said disks. The arrangement illustrated includes a type carrying plate 152 1) carried in aline- I mentwith that row of printing type-races which is in set position and'this plate is relatch 15.4.

The machine will always stop in the same DOSiiZiOii at the completion of a full revolution of the crank shaft- 18 atter the operator releases the treadle rod 44 to allow it to drop, whether the machine has completed only one or any number of printing operations.
