Application filed. September 17, 1925.

This invention relates to marking machines and is illustrated as embodied in a marking machine in which a narrow strip of material is fed intermittently to the printing position so that successive impressions may be made at regular intervals thereon.

In factories, such as garment making factories, or shoefactories, where the work is divided int-o a large number of operations, it is common practice to provide a tag, having as many sections as there are operations to be performed, which is attached to a bundled lot of material. These tags may be printed in advance with legends in the sections to vshow the various operations and are marked at the time of use to indicate the particular lot or class of material to which they are attached. The custom then is for each operator to remove a section of the tag which corresponds to the particular operation which he is performing so that he may turn in to the accounting department printed slips which will show the amount of work performed and hence the wages to which he is entitled. These slips may be arranged to contain other information which may be desired as a record Commonly, these tags are made of long narrow strips of thin cardboard and the sections to be removed are small in proportion to the length of the tag because of the large number of different steps or operations to be performed. Factories of this sort commonly have marking machines in use for various other purposes the marking mechanisms of which are well suited to marking on the tags the various items of information repeated on each section, such as Lot No., Case No., Quantity, etc., but such machines have not been adapted for feeding tags of the type referred tto conveniently and rapidly to the markingV apparatus in such a fashion that the imprints will be made in proper positions with respect to the sections of the tag.

Accordingly, it is an object of this invention to provide a marking machine having improved work feeding mechanism arranged to move a relatively narrow Strip of material along step by step and capable of use for feeding a wide variety of tags. To this end, and in accordance with features of the invention,

` the illustrated work feeding means is arranged to facilitate the introduction of work, so that the forward movement of the work PERLEY R. GLASS, OF WAYLAND, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MA- Y CHINERY CORPORATION, OF PATERSON, NEW JERSEY, A

may be adjustably predetermined with accuracy, and is provided with guiding, retaining and feeding members adjustable laterally to accommodate strips of work of varying widths and to position thestrips correctly with relation to the printing apparatus in order that the imprint may occupy the desired relation laterally of the work.

Y These and other featuresof the invention which will be pointed out in the claims and described in the specification are illustrated in the accompanying drawings, in which Fig. 1 is aside elevation of a marking machine having embodied therein novel work feeding mechanism constructed in accordance with the present invention.;

Fig. '2 is a perspective view with parts of the work feeding mechanism broken away;

Fig. 3 illustrates a section of an Villustrative tag such is used in a shoe factory; and

F ig. 4 is a fragmentary perspective view of one set of feeding jaws.

The illustrated work feeding mechanism is provided with a bracket which may be removably attached to a marking machine in place of the bracket holding the work table normally used in the machine, and the arrangement is such that, after the operator has inserted a piece of work between guides upon a work supporing table, the machine may be started and continued in operation until the desired numbers have been repeated on each section of the tag with the assurance that the printed impressions will occupy the desired positions both laterally and longitudinally of the piece of work. Y

The illustrated marking machinev which, except as herein illustrated and described'in detail, is organized as disclosed in United States Letters Patent No. 960,029, granted May 31, 1910, upon the application of F. W. Merrick, comprises a type carrying head 110 secured atthe lower end of an upright arm 112 which is pivotally attached at 114 to the outer end of the operating lever 90 and at its upper-end to a link 116 pivoted'in the machine. This arrangement provides for movement up and down of the type carrying head to bring the markers into contact with the work and during this up and down movement ink may be supplied to the marking type by means of a roller 118 pivotally secured at the outer end of a lever 120 and resiliently held against the type by a spring pressed plungerv 122. An ink reservoir 124, embodying a supply roll 126, is mounted in an auxiliary bracket 128 also attached to the frame of the machine.

The work feeding mechanism comprises a supportin bracket 10 attached to the frame 12 of the machine. 'lhis bracket 10 has lateral arms 12', between which extends a web 14 havingY formed centrally thereon a forwardly extending' bracket arm 16. 'ihe outer end 127 of this bracket arm 16 is T- shaped and provides means for attaching a work supportingtable 2O extending' rearwardly from the forward end of the bracket to an intermediate point, adjacent to which there is provided a platen 22 supported upon a removable cross member 24 attached to the bracket 16 with screws. Overhangingr guides 26 are adjustably attached to theupper surface of the work table 20 by bolts passing` through slots 2S in said table and the outer ends of these guides are flared, as shown at 30 to facilitate the insertion of a piece of work into the guides. Spring' pressed work retainingaws 32 are pivot-ally mounted above the table to prevent retrogra de movement of the work and in the pa ticular construction herein illustrated these jaws are pivotally mounted directly upon the guide members 26 so that they are laterally adjustable with said guide members. It will be apparent that the arrangement illustrated and described makes itvery easy for the operator to insert work into the `guides 26 and under the jaws 32, and that it provides for varying widths of strips oi work and allows the centering,- of the work with respect to the platen 22 or an exact lateral adjustment with respecttov said platen to any position which may be desired. ylhe retaining' jaws 32 are provided with finger pieces 34 beneath which are springs 36 serving to hold the serrated. forward ends of the jaws normally in engagement with the work, `the serrations or teeth sloping in the direction of work feeding movement acting to prevent retrograde movement without' hindering; the forward feeding movement of a piece of work. Manually operable means are provided for intermittently releasino; said retaining jaws, when it is desired to rinsert a tag. which means is arranged to ceopcrate with the finger pieces 34 upon the retaining;` jaws in whatever position of lat-eral adjustment they maybe placed. To this end arms 38 and 40 are privotally mounted upon a rod/l2 secured in bearings formed upon the T-shaped end 17 of the forwardly extending` central bracket arm 16. rlhese arms carry attheir outer ends a pair et parallel rods 44 and 46.v and the upper rod 44 overlies the finger pieces 34 in any position which the latter may occuj The lower rod 46, as later described, arranged .to co-operate with feeding jaws 52 and A slot 48 1) is provided in the forwardly extending bracket arm 16` for the passage of the lower rod 46.

ri`he mechanism for intermittently feeding the work forward step by step is mounted upon a shaft 50 jonrnaled inthe lateral arms 12 of the supporting bracket 10. This mechanism comprises the upper jaws 52 and 54 and cti-acting lower jaws 56 and 58, .each set of jaws being pivotally mounted at the upper end of a corresponding` arm 60, two of these arms being adjustably secured in the desired positions on `the shaft 50 and clamped thereon by bolts 62. The feeding jaws are thus arranged to grasp the work at points outside the work support, and, as here shown, upon opposite sides et the platen 22 adjacent to its enes. Each of the lower jaws 56, 58 is serrated to grip lthe work and is provided with a depending, forked lever 64, the forked lower end of which overlies transverse rod 66 supported in similar bell cranks 6@ loosely pivotcd on the opposite ends of the transverse shaft 5() oiiitside the bracket arms 12. Springs .70 to hold the jaws in gripping contact rare provided which are interpo il between flanges 74 fori ed upon the sides of the depending forked levers 64, and arms 'T2 formed as an integral part of the upper jaws 52 and 54. rEhe ellect of these springs as they tend to rotate the jaws about 4their common pivot is limit-ed by stops 71 (Fig. 4) formed upon the inner sides of arms 6.) which contact with the flanges 74 and by `stop screws .73 passing upwardly through said stops and abutting' the under sides Yof the upper jaws 52 and 5K4. By adjusting;` the Ystop screws 73, the level at which the upper and lower jaws grip the tag may be determined to bring it substantially into coincidence with the plane of 'the upper surface of the platen 22. Extensions 76 are provided upon the upper jaws 52 and fffwhich, in any position of lateral adjustment and in one operating;` position of the feeding jaws, underlie the rod 46, thereby to make the manually operated rod 46 elf etive'to open the feed vjaws, when it is desired to insert and adjust a. piece of work.

actuation of the feedingA jaws cllected a connecting rod 80 pivotally secured at its outer end to ene of the bell crank levers 68 and at its other end adjustably secured. in a groove 82 in a. bell crank lever 84 pivotallv mounted in the bracket 10 and havinpv another arm 86 which is connected by means of a rod 88 to the actuating` lever 90 of the marking machine.

rlhe arrangement of the iarts such-that, as the type carrying head of the marking machine is lowered, the feeding `jaws grip the work outside the platen and the work support and are moved away from theoperator to feed the piece of work so as to bring a fresh portion of the strip into position over the platen 22. It will be understood that the amount of feeding movement may be adjustably determined Vby varying the point of. connection of the rod 8() in the groove 82 of the bell crank lever 84C. Thus, if the piece of work at hand is a tag such as is illustrated in Fig, 8, the amount of -feeding movement is adjusted to bring the impresses within the sections indicated by cross lines 92 on the tag. The particular tag illustrated has been previously printed with the name of each individual operation., as indicated at 94, in each of the sections, and preferably with the wage which will be paid to the operator for the particular operation listed on the tag, as represented at 96. The function of the machine then is to imprint duplicate numbers such as those indicated at 98, which may convey7 to the accounting department the desired information such as lot number, case number, etc., of the work to which the tag was attached.

It has already been pointed out that the transversek operating rod 66 is in engagement with the forked ends of the levers 6st upon the lower jaws. It should be noted, also, that this rod passes under hooked projections 100 integral with the jaw supporting levers 60, and the space provided bctween these hooks 100 and the levers 60 is such that it forms a lost motion connection, with the result that movement to the right (viewed as in Fig. l) of the connecting rod 8O serves to move both'sets ofjaws along together to feed the work. ahead toward the frame of the machine while a reverse movement acts first to 4depressthe serrated lower jaws 56 and 58 away from the work and then to carry the feeding jaws back to starting position while the 'work is held by the retaining jaws 32. In order that forward movement of the tag may not be interrupted by Contact of a tag with theV frame of the machine when the tag is of' considerable length, a curved work deflecting plate 102 is secured between the side arms 12 of the brackets 10 which is suitably curved to delect the forward end Vof the tag downwardly away from the frame of the machine so that it may be printed along its full length and then allowed to fall into a suitable receptacle beneath the machine.

The arrangement described providesfor the lateral adjust-ment of the work guides 26 and the retaining jaws 32 simultai'ieouslyv with respect to the work supporting table 20, so that various widths of tagsmay be handled and properly positioned with respect to the platen 22 or the type in the head- 110. The arrangement also provides for the lateral adjustment of the feeding jaws by adjustment of their supporting arms 60 upon their shaft 50 in' order that these jaws may beV brought into proper relationship with the edgesof a piece of work. After the machine has been started its operation becomes automatic and the work is fed forward step' by step a distance determined by the adjust-ment of the end of the connecting rod 80 in the groove 82. During this feeding movement the tag is intern'iittently grasped by the feeding jaws while the re-` taining jaws are arranged so that forward movement is not hindered and retrograde movement is prevented. During the work feeding movement the rod 66 cooperates with the depending forked arm 64 to open the feeding jaws by moving the lower jaws 56 and 58 downwardly while the upper jaws are prevented from rotating by means of the adjustable stop 73. On the other hand, when the machine is at rest and the manually operated rod 4:6 is depressed, this is effective to open the feeding` jaws by lifting the upper jawsr52 and 54 away from the lower jaws, which latter are held in position by reason of the engagement of their arms Ga with the operating rods 66.

Having thus described my invention, what I seek to protect by Letters Patent of the United States is l.
