Specification of Letters Patent.

Patented sept. 19, 1916.

Application filed March 15, 1912. Serial No. 684,074'.

To all whom t may concern Be it known that we, RICHARD L. LLOYD and ROBERT D. SIMPSON, citizens of the United States, residing, respectively, at

Portsmouth and Columbus, in the counties,

respectively, of Scioto and Franklin, State of Ohio, have invented certain new and useful Improvements in Machines for Marking Buttonhole-Flies, of which the following is a specification.

This invention relates to the marking of shoe uppers to indicate the position on the upper where certainy operations are to take place, such as the making of buttonholes, attachment of buttons, etc. l

It has been the practice to mark the loca-- tions of buttons and buttonholes on the shoe upper material by piercing or indenting the material of the upper with a marking tool or a series of marking devices forming part of a marking machine. In certain upper materials, such as soft lea-ther, cloth, canvas, etc., vthe puncture or indentation subsequently closes up or disappears so that when the time arrives to utilize the indication mark it is not discernible. It` has also been the practice to mark upper materials with inked markers but the ink has a tendencyy to spread particularlyv in cloth and canvas, and the exact location of the mark is not easily ascertained. Furthermore the appearance. of the upper is injured by the spreading ink or colored dye. When chalk is used the mark becomes smeared and the indication is so blurred as to be useless.

A conspicuous feature of our invention consists in a machine forA marking vshoe up-' per materials provided with marking means arranged to place a dry indelible indication upon the upper material which will always be discernible by contrast with the adjacent unmarked portions of the material. Incidentally the machine involves the application of a novel method of marking uppers. 7e accomplish the result stated by employing heated markers to cauterize the surface of the material. Preferably these markers are electrically heated.

Another feature of the invention consists in a structure Vproviding two series of cauteriZi-ng markers with means for causing a heating electric circuit to pass through either series. Such al construction permits the marking of either face of the material.

A further feature resides in anovel construction of electrically heated markers.

Another feature of the invention consists inl two series of alined cauterizing marker elements with means for simultaneously moving both series of elements to vary their relative spacing, and with means for heating either series of marker elements.

A still further feature of the invention consists in the means foradjusting a series of markers longitudinally of a guiding element so as to determinately vary the spacing between the markers. 'y

These and other features and advantages will be more fully apparent from a reading of the following specification in connection with the accompanying drawings, in which- Figure l is a. front elevation of amarking machine constructed in accordance with a preferable embodiment of the! invention; Fig. 2 is atransverse, vertical lsection of the machine sho-wn in Fig. l; Fig. y3 is a top plan view of the machine shown inl Figs. l and 2, the cover beingv removedv to ldisclose the interior arrangement; Figs. 4; and 5 are views in top planand front elevation of the knee operated lever element for controlling the spacing ofthe marking elements; Fig. Gis a plan view of the yoke by means of which the lower series of marking elements are moved to effect marking of the work; Figs. 7 and 8 are views in side and front elevation respectively of one of the movable blocks carrying the upper and lower marking members, the block shown in the present instance being one of the terminal blocks of the series; Fig. 9 is a view in front elevation of the other terminal block of the series,

including the switch for directing the heating current to the upper or lower series of markers; and Fig. 1() is a top plan view of the parts shown in Fig. 9; and Figs. 11 and 12 are views in top plan and side elevation respectively of one of the links connecting the marker carrying blocks with the spacing lever; Fig. 13 is a diagrammatic view illustrating the current distribution and control; and Fig. 14 is a detail, in section, of the end gage used to position the end of the work relatively to the markers.

The machine comprises a suitable support including a tubular standard l whose upper end is secured to and supports a base 2, upon which is mounted a rear wall 8 and side walls h1 forming a housing- .for the operating parts of the machine. A hinged cover is preferably provided for the housing. At the front edge of the base a work supporting board or plate is secured and is formed to provide its inner edge with a curve cor responding substantially with the curve of the buttonhole Hy of a shoe upper. From the curved edge of the work support rearwardly, the base 2 is slotted, as shown at G, the rear edge of the slot having an upstand- .ing flange or guide plate 7. This guide plate is intended to receive and guide a series of marker carrying blocks or marker units for movement longitudinally of the guide to vary their spacing. These units or blocks, indicated at S, have their lower rear faces inwardly offset and provided with vertical bifurcating slots 9 therein extending upwardly from the base of the block. rlhese slots are of suiiicient width to receive the guide flange or plate 7 therein, so that the blocks are supported on the guide plate by means of these slots. The front face of each of the blocks, at a point between its upper and lower end, is recessed inwardly, as at 9 to provide space for the insertion of the edge of the fly so that the work may be positioned between spaced upper and lower marking elements mounted on the block above and below this bifurcation. The outer face of each of the blocks above and below the recess 9a is provided with insulating strips or plates 10 and 12. The upper plate 10 carries an insulated stud 11 and the lower plate an insulated stud 15 to which the marker elements are secured, as later explained. The lower insulating` plate 12 is provided with a longitudinal slot 1-1 therein extending vertically of the block and pins 13 secured to the block S extend through this slot and guide the lower plate 12 for vertical movement toward the upper plate 1() which is .rigidly secured by suitable means to the outer tace of the block. The bases of the lower insulating plates 12 carry resilient hook elements 16 adapted to clasp the edge of a frame 17 positioned below the bed 2 and pivoted at its rear end at 19 to the bed of the machine. The engaged edge of the bar 17 of this frame is formed on a curve corresponding to the curve of the slot 6 and curved edge of the work support 5. It is arranged to be moved upwardly to move the lower insulated blocks l2 upwardly, by nieans of a pivoted link 20 attached at its lower end to a bar 1S of the frame and pivoted at its upper end to a lever 21. rlhis lever is t'ulcrumed at 22 upon the base of the machine and has at its forward end a pivoted rod 21L extending downwardly through the tubular standard 1 with its lower end in turn pivoted to a treadle 21b having a lateral oliset, (Fig. 1) arranged to be engaged by the foot of the operator. Movement of the treadle downwardly serves to pull the frame 17 upwardly through link 20 so that the series of lower insulated plates 12 are moved upwardly toward the upper series. At the same time, the rear end of lever 21 is arranged to close an electric switch in a circuit which includes electrically heated markers carried by the upper and lower series of insulated blocks 10 and 12. To this end, a projecting bar switch 23 is carried by the rear end of lever 21 with suitable intermediary insulation and is arranged to engage and bridge spaced switch contacts 21 when so moved. break in the circuit has been closed through a manually operated selective switch, the current will pass through either the upper or lower set of marker elements carried by the insulated series 10 and 12. The marker elements are formed by a single length of flexible, conducting ribbon 25, which extends along the upper series of plates l0 and is provided with V-shaped portions, the lower ends of which engage the insulated studs 11, this ribbon at one end of the series of upper plates 12 being then bent downwardly and extended along the line of lower plates 12 in a similar manner with inverted V- shaped portions or loops embracing the insulated studs 15 of the lower series of plates. The extremities of these loops or V-shaped portions are in the form of sharp bends 2G which proj eet above the edges of the inward recesses 9a of the blocks. The terminals of the conducting ribbon 25 opposite the closed end of the ribbon or at the left end of the series shown in Fig. 3 are connected with switch jaws 27, 28. Adjacent these switch jaws is located a manually controlled selective switch in the form of a pivoted switch blade 29 having an operating handle 30 and arranged in line with switch jaws 27, 28. By connecting the blade 29 with one of the jaws 27 or 28, the current maybe caused to pass through either the lVhen a second upper or lower series of marking bends 26 of the ribbon 25. The ribbon itself being fiexible, provides a series of longitudinally extensible and contractible cauterizing portions as well as two series of opposed cauterizing portions relatively movable. The electric circuit for effecting this heating is best seen in Fig. 13 in which a wire 35 leading from one side of a source of current is connected to one of the spaced contacts 24 of the bridge switch. The other contact of the switch is connected with a resistance coil 37, the opposite end of this coil being in turn connected to a rheostat 38, the current passing through the rheostat and out by a wire 31 to the knife switch 29, thence through either the upper or lower series of marking bends 26 of the ribbon 25, depending upon the connection of the switch blade 29, to the other side of the source of current. A wire 34 is connected to the closed end of the ribbon 25 and leads from said ribbon-to the other side of the current source.

1t will be understood that in marking the buttonhole fly, it is placed upon the work support 5 with the edge of the fly extending into the recess 9a of the blocks 8 and positioned by eye so that the edge of the fly is spaced from the markers substantially uniformly and for the desired distance. The end of the fly is positioned at the appropriate distance from the first marking element of the series by means of an end gage in the form of a swinging arm 39, whose end forms a stop against which the end of the fly rests. This end gage may be swung to vary the distance of the first mark from the end of the fly by means of a thumb bolt 39a. The number of buttonholes to be marked as well as the relative spacing between the buttonholes will vary in different shoes and consequently, before the treadle 21b is operated to close the circuit and lift the lower series of markers, the markers themselves should be properly adjusted. These markers will bear certain indications, such as numbers, by means of which the operator can readily utilize the desired number of marking elements. To space properly the selected number of elements, the following mechanism is employed: Each of the series of blocks 8 except the first one has its rear formed with a perforation or socket 42. At the rear and right end of the base, as viewed in Fig. 3, a spacing lever 43 is fulcrumed on a vertically extending shaft 47. This lever 43 is provided with a plurality of longitudinally extending and alined journaling apertures therein and a series of links in the form of rods 40 are arranged to connect this adjusting lever with the successive blocks 8. To this end the rods 40 are each bent to a particular form and at their forward ends are provided with depending portions 41 seated in the sockets 42 of the blocks 8. At their rear ends these rods carry threaded sleeves 44 having extensions 45 with depending pins 46 designed to journal in the successive apertures in the adjusting lever 43. The threaded sleeve 44 provides for adjustment of the length of the rods. The links 40 and the lever 43 are figured to provide a definite and ascertained movement of the links 40 and of the blocks 8, connected to their outer ends, so that when the adjusting lever is moved the links 4() will slide the blocks longitudinally on the guide plates 7 and will space the blocks equally at various points of movement of the adjusting lever 43. The spacing of the marking blocks occurs from one end of the series and relative to an end block of the series which is fixed. In Fig.' 3 of the drawings this end block is found at the extreme left hand end of the series and is secured in desired position on the guide plate 7 by means of a set screw 48. It is, of course, understood that there is no link 40 connected to this fixed marking member. Movement of the lever 43, will, therefore, move the successive blocks from and toward each other and from and toward the fixed end block to give the desired spacing of the markers carried by the blocks. The adjusting movement of the lever is preferably limited by stop pins 49 and 50 (Fig. Adjusting movement of the lever is effected by the operator through a rod 51 co-axial with and depending from the shaft 47 which forms the axis about which the lever turns. This rod 51 has detachably secured to it the rear end of a bar 52. As seen in Fig. 4, the rear end of this bar is formed as a split socket or collar 53 with an operating handle 54 arranged to clamp the collar about the rod 51. The forward end of the bar 52 is provided with an elongated slot 55 therein with a cross bar 56, which is dovetailed into the slotted portion of the bar 52 and has a wing nut 57 for clamping the cross bar at various distances from the forward end of the bar 52. This adjustment enables the cross bar to be positioned according to the location of the knee of the operator which is to be inserted between the spaced rods 58 and 59 depending from the cross bar 56 and adjustable on the cross bar by means of nuts 60 and 61. Movement of the operators knee will swing the bar 52, turning the rod 51 and shaft 47 to swing the adjusting lever 43. V

With the fly inserted between the properly spaced markers, the operator depresses the treadle 21B, moving upwardly the lower set of insulated blocks 12 with their marking points to engage the iy between the two series of marking points, the ribbon 25 being sutliciently ileXible to permit this movement. lVhen the knife switch 29 has been moved to close the circuit through the lower series of marking points, the under face of the ly will be cauterized to provide a series of dry indelible marks indicating the locations of the buttonholes. It' the upper series of marking points has been energized, these points will similarly mark the upper face of the fiy. The indication mark made by the eauterizing of the surface of the upper material is not only dry and indelible, but will always be clearly discernable, whatever the nature o'l the materials, because of the eifect of the cauterization upon the material itself. The cauterization will always change the color of the canterized spot either to a different shade so that the mark will be discernible under all conditions.

The novel method herein disclosed, which is characterized by the step of cauterizing the surface of the material to form indicating marks, is not claimed herein but forms the subject-matter of our divisional application liled February 8, 1916, Ser. No. 76,940.
