NEWELL V. DYER, OF'HOLBROOK, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

MACHINE FOR MARKING MATERIALS.

To all whom it may concern:

Be it known that I, Nnwnrn V. DYER, a citizen of the United States, residing at ldolbrook, in the county of Norfolk and State of hl'assachusetts, have invented certain, Improvements in Machines for Marking. hflaterials, of which the following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawings indicating like parts in the several figures' My invention relates to machines for marking various objects, and particularly to those employed in marking portions of shoes. For such work the usual practice is to arrange the stock, when out, with the corresponding pieces of the right and left shoes of a. pair together; and to identify them unmistakably before they go to the operators for assembling, there are placed upon them symbols indicating, for example, the case number, size, width, and match Ordinarily, these indications are applied to the flesh side of one of the pieces of a pair, after which the symbols are similarly placed upon the other piece.

This invention has as an object the provision of a machine whereby different surfaces, as those of pairs of shoe parts, may be marked by a single operation in an effecti've manner.

A feature of the invention consists in a machine for marking, in which pieces are placed together and oppositely or simultaneously impressed with the symbols identifying them. When these pieces are shoe parts, the corresponding pairs of pieces are laid with their finish surfaces together, and the impressions made atthe same time upon the opposite sides. p

In thepreferred embodiment the impression members move oppositely to exert independent pressure upon the work. This independence of effect is preferably obtained by means of separate pressure-receiving members cooperating with the impression members. To avoid'interference with the placing of the work between the impression. members, at least one of the pressure-receiving members is movable, so that it may be withdrawn from the line in which the work is introduced.

pressions are so arranged upon marking members that one of a plurality may be brought into use at a time, as a further feature, the marking members bearing these surfaces are so organized that a plurality of these members may be selected and then simultaneously acting surfaces brought into position, the selecting and positioning of the plural members and. surfaces being respectively by a single operation.

These and other features are more fully set forth in the following descriptionand illustrated in the accompanying drawings, wherein Figure 1 shows. a front elevation of one embodiment of my machine;

Fig. 2 is a side elevation thereof;

Fig. 3 is a longitudinal section illustrating the impression. members and their supporting and actuating elements, together with a portion of the setting mechanism;

Fig. 4: is a similar view showing the mechanism for applying the marking agent to the impression surfaces;

Fig. 5 is a broken perspective view of the setting mechanism Fig. 6 is a longitudinal sectional detail through one of the series of impression members; and

Fig. 7 is a detail in side elevation, show ing the parts as; producing their impression upon two piecesof material.

A casing 10, in which the operating ele ments of my improved machine are mount-- ed, is provided at its front with recess, at the lower side of which is a horizontal worksupporting surface or table 12. Entrance to the parts within the. casinguis provided for by removable panel's-14f situated at the front above and below the tableand' also at the rear of the casing. Extending transversely of the casing are horizontal shafts 16 and 18, shown as situated just above and below the line of the table, and upon these, shafts are fulcrumed levers 20 and 22, forwardly extending arms of'which have fixed between them spindles 2 f carrying the marking members, here shown as consisting of series of adjacent type or die, disks 26. These disks have extending radially from their peripheries teeth or projections 28, at the extremities of which are surfaces for producing the impression upon the work,.these surfaces being in the form of any desired symbols, as numbers or letters. The disks are mounted to turn upon the spindles and are held at the angle to which they may be adjusted by retainin members, there being one for each series or disks, common to the entire series. Each retaining member may consist of a rod 36, located within recess 32 extending along one side of the s indle and capable of engaging any one 01" series of grooves, semi-circular in cross-section, formed in the openings through the disks about the spindle. To hold each rod 30 in engagement with the disk 'rooves, springs 36 are placed at each extremity, these resting in boxes in the spindle and acting to force the rod outwardly.

To move the levers 20 and 22 and the stamping members carried thereby toward and from the table 12 and a secondary pressure-receiving member or abutment '38, to be later described, their rear arms have projections entering eam-grooves a2 in disks fixed to transverse shaft 44: ournaled in the rear portion of the casing. The projections l0 may be separately fixed to the lovers, as by screws. The shaft M has secured upon it a gear 46, with which meshes a pinion 48 fast upon a power-shaft 50 journaled at the extreme rear of the casing. On this power-shaft are fast and loose pulleys 52, with which may cooperate a belt (no shown) receiving motion "from some suitable source of power. The gear 46 is preferably joined to the shaft 44 through a. clutch, indicated at 54, this being of any suitable type, preferably adapted to cause a single rotation of the shaft upon its release by a rod 56 hich may extend to a treadle (not illusted). The cam-grooves -12 are similar in :form but are oppositely placed, being separated by an an e of 180 degrees, and cause the stamping sks to be simultaneously moved toward one another and the corresponding table or abutment, after which they returned to their normal positions. To allow the impression surfaces or dies to make their impressions yieldably, the rear arm of each lever 20 and 22 has a section 58. pivoted at 66 upon the main lever and ac"- ing against a spring 62 interposed between the lever and section. in the rear extremities of the sections are the pins 40, and, while these constrained to move through vertical paths of unvarying lengths, the dies, by virtue of the springs 62, may yield in accordance with the thickness of work with which they are brought into contact. Firm pressure is thus assured without danger of injury to the work or of breaking the marking mechanism.

The vertical alinement of he upper and ower die disks is such, that when those car- 'ied by the lever 20 are actin upon work supported on the table: 12. those mounted upon the lever 22 projects through an open ing 6% in the table at the rear of the upper dies and produce their impressions against the presstire-receiving member To leave the space above the table 12 clear for the introduction and withdrawal of stock at the beginning and end or the operation, the member 38 is movably mounted in the cas ing 10, it being illustrated as sliding in inclined ways 66. in the member 38 a rack 7 68 is formed, with which meshes a gear-segment 70 at the extremity of an arm 72 ast upon the shaft 16. As lever 20 and its die disks 26 descend to produce their inipression and the lever 22 and disks rise, 8 the member 38, through the gearing 68, '70, is moved down toward the opening 64 to meet the lower impression members 26, forming an abutment which takes the impression upon the lower piece of stock equal a in efficacy to that furnished by the table for the upper dies. in the opposite or retreating movement of the die disks, the member 38 is withdrawn to a position at which it is clear of the space above the table, so that it does not interfere with the introduction of the next piece or" work.

To apply a pigment or marking agent to the dies, pads or other members 74: for carrying such agent are supported upon arms 76 9 pivoted upon a slide 78 movable in horizontal ways 80 in the frame. At its rear extremity, the slide has slotted connection with a bell-crank lever 82, fulcrumed in lugs 8d rising from the bottom of the casing. The other arm of the lever has a projection 86 extending into a cam-groove 88 in a disk fixed to the cam-shaft a l. As the cam-shaft rotates and the die-l vers are oscillated, the bell-crank lever reciprocates tie slide 7 8 from rearward position, at which the pads 74 are clear of the die-disks, forwardly be neath and above said disks, and 'in this movement projections 90 from rearward extensions of the arms 76 enter opposite grooves 92, one of which is inclined upwardly and the other downwardly from the horizontal. Under the influence of these grooves, the 76 are swung upon their pivots on the slide, so that, as the pads reach points opposite the dies, they are pressed against dies to apply the marking agent thereto. This occurs at the time that the stamping disks are in their normal position. Thereafter, the slide is moved back and the pads withdrawn to their initial points clear of the paths through which the die-disks move in the oscillation of the levers.

In the work for which this machine is particularly designed, it is customary to impress the same symbols upon two sheets of material arose id to it. I therefore furnish Fo simultaneously setting the corresponding upper and lower die-disks, and also for simultaneously selecting which pair of disks shall thus be adjusted, by setting means common to the respective series. In their resting positions, the teeth of the disks 26 mesh with series oi toothed setting disks 94 mounted between cheeks upon the casing on the upper and lower spindles 96, 98, re spectively. These spindles are journaled for rotation and for axial movement in the opposite walls of the casing, they also sliding through the disks 94. The spindle 96 may be turned by a hand Wheel 100 last upon one end, and the spindle 98 is arranged to rotate with it at the same rate by' gearing consisting of sprocket-wheels 102 splined upon the spindles and a chain 10 1 operating over these wheels. In the hubs of the sprockets are grooves 193 into which extend projec ions from the frame, iolding them against bodily movement. The chain 104 passes rearwardly from the sprockets 102 over idlers 106 and 108. The former is shown turning upon the shaft 16, while the latter is rotatable upon an arm 110 pivoted upon the side of the casing and urged against the chain by a spring 112 actii to swing the arm to the right, as viewed in 2 of the wing, thus keeping the chain properly taut. Projecting radially from each of the spindles 96 and 98 is a pin 11 1, which, in the axial. movement of its spindle, may be brought into one of a series of recesses 116 arranged in the central opening of each dish about the spindle, there be ing a recess of the series opposite each tooth, and, by this engagement, the rotation of the spindles may be communicated to the disks. To simultaneously aline the spindle projections with a particular pair of disks which it may be desired to turn and to confine the setting action to the pair thus selected, the spindles 96' and 98 each have connected to hem by opposite end pieces 118, 118, spindles 120 and 122, all mounted. to reciprocate through openings in the sides of the casing similarly to the spindles 96 and 98. The spindles 129 and 122 have teeth 124 out on opposite sides to furnish racks, with which mesh pinions 126, 126 near the upper and lower extremities of a vertical shaft 1.28 journaled in bearings in the top and bottom walls of the casing, and provided at its upper exremity with a hand-wheel 130 by which it may be turned. On rotating this hand Wheel, the pinions and racks shift the frames "formed by the spindles and side pieces in opposite directions to bring the projections 114. into one or another of the pairs of disks 9 1. An index finger 132 is shown as fixed to the upper spindle 122, pointing to the disk which has been selected, that is, into which the projection 11% has been carried; and to show the operator the symbols which are upon the corresponding disks 26, the projections of the disks 9 1 have inscribed upon them the respective symbols.

therelations between the elments being such that when a symbol is beneath the index finger, like symbols are in marking position upon both of the corresponding disks 26. To look against rotation all the disks 9i ex cept the pair at the time in setting engagement with the projections 114, the spindles 122 have extended lateral projections 133, which enter between the teeth of the disks 94 and hold them 'from turning. Through these projections 138, corresponding to the position of the index finger, are grooves 134. of such dimensions to permit the rotation through each oi them of a single disk. It the operator wishes, for example, to set the die-disks, the index figure for which appears on the third. from the left of the upper series oi disks 94 in Fig. 5 of the drawings, he moves the spindle frames by turning the shaft 128 until the index finger 132 occupies a position over this third setting disk. This will move the projections 11a of both the spindles 96 and 98 into corresponding upper and lower die-disks 26, and will look all the setting wheels 94 except-the selected pair, which are alined with the grooves 184; in the spindles 122. Then, by means 01 the hand wheel 106 and the gearing connecting the spindles 96 and 98, he turns the selected setting disks through the engagement of the projections 114 until the character chosen upon the third disk is beneath the index point. This indicates that the impression surfaces of both die-disks selected are in the marking position.

Assuming that my machine is to be used for the purpose of marking parts of shoes upon the flesh side of the leather, the various correspondingpieces of the shoes of a pair are arranged with the grain sides together, and the die disks are set just described to give the desired case, size, width and match designations. The operator then lays a pair of the pieces upon the table 12, as shown in Fig. 7, and starts the op'er tion of the machine by engaging the clutch 5 .1. The cam mechanism first moves the pads 74"into contact with the lines of chosen characters upon the die disks, withdraws them, and then moves said disks against the work, the member 38. receiving the pressure of the lower series of disks, while the upper series acts against the table. This, at a single operation, impresses upon both pieces of thework the same identifying designation,

, and. the cam mechanism then withdraws the Having fully described my invention, what I claim as new and desire to secure by Letters Patent oi" the United States is 1.
