-May 14, 1935. c c o cs 2,000,921 I MARKING MACHINE Filed Oct. 26, 1932 5 Sheets-Sheet 3 v //\/\/E/\/ TU thoughthey are of uniform thickness, may be thicker or thinner than other soles. To insure that the sole is marked clearly at its edges the work marking edge of the tool 22 is slightly bowed so that the pressure of the toolis greater at its ends'than at its midportion.

When 'the drive shaft 4 isrotated the marking tool 22 isswung: downabout the axis of the pivots 20 of the marking tool lever I6 toward a horizontal work supporting table fixed to the" front of the frame 2. The edge of the plate 22 which forms the marking tool is brought into. contact with a sole placed onthe work supporting, table 30 to mark a straight line across'the'sole' at the ball line from edge to edge thereof and thus indicated where the operation ofshank reducing should begin or end. a

Rotatably mounted in the frame 2 below the table 30 is a horizontal shaft 32 which extends across the machine and is prevented from moving axially by a collar 34.at one end. and a hand wheel 36 at the other end. The .collar 34 and the hand wheel 36 engage the side faces of the frame 2 and the shaft may be'rotated byturning the hand wheel 36. The shaft 32 is-provided with rightvBy means of-the right-and-left-hand threaded portions of the shaft 32 the bars 40 andtheir pins 42 may be adjusted toward and from each other to position laterally a sole to be marked as later described. Since, asnotedabove, the machine is arranged so that either, rightorleft; soles may be presented alternatively, the spacing of thegages 42, as measured in a direction parallel to the abutment plate 50 between linesfrom said gages normal to the plane of the abutment; will be greater than the'width of a sole. In other-words, the .dis-

tance between projections from said gages upon thepabutment 50 or an extension thereof, if out side the abutment, will be greater than the width of a solethereby; bringing the longitudinal ax-isof a sole, positioned asillustrated in Fig. 3,- at an angle with the abutment which is less than a f ht angle. The word projection is here used in the mathematical sense to mean a line let fall from a particular point, said line being normal to the surface or line uponwhich it is projected. This will also bring,- the axis at an acute angle to the elongated marking tool 22. g

Y A third bar 46-is arranged to be moved forwardly and rearwardly 'of the-machine. The bar 45 is guided, in a groove formed in theunder side of the work table 30and is supported on the face of the frame '2 towhich the table is fixed. The bar 46 may be locked inposition by a hand screw 48 (Fig. 1) extending upwardly through a boss formed at the front of the machine'frame and engaging the under side of the bar 46 to clamp it in position. 'Fixed to the rear end of the bar 45 is an end gage plate 50 which extends upwardly above the upper face of the work "table 30' and across. the machine. The gage plate 5ll,'fin' the form of a straight abutment, is used to position the toe end of the sole which is to be marked at the ball line. A gage block 52 (Fig. 5) may be placed on the gage plate 50. This block has in its front face a V-shaped recess 54 in which the heel end of the sole is placed. The gage block 52 is held in position on the gage plate 50 by a pin 56 in the gage block which enters a vertical recess 58 (Fig. 3) in the top of the plate 50 which positions the block centrally of the work table, the block 52 resting on top of the bar 46.

The work table has a mark 60 (Fig. 3) extending across its upper face which coincides with the position of the marking tool 22 when the tool is swung nearly into contact with the upper surface of the table. The right front pin 42 is cut away forpart of its length on the outer side so that a fiat surface 62 thereon (Figs. 2 and 3) serves as an indicator and cooperates with a row of index marks 64 on the upper face of the work support 30 which indicate the distance apart of the two sets'of pins 42 onthe bars 40. The bar 46 has a row of marks on its upper face which by their relation to an edge 65 of a. recess in the tableindicate the position of the gage 50 rela tively to the mark 60 on the table.

By means of the mark 60 the operator is enabled to place by eye a sole on the work table 30 in correct position to be marked at the ball line 'bythe marking tool 22 when the machine is put into operation. Then the gage plate 50 and two of the lateral gage pins 42 may be moved into engagement with the sole contacting therewith at three places, so that subsequent soles of the same size and shape to be marked may be quickly positioned upon. the work table by being placed against the gage plate and the pins. 7

When the soles are to be marked at the ball line the gage 521s removed andthe toe end of the sole is positioned by the gage plate 50 to determine the distance of the mark from the end of the sole. The angle of the mark in relation to the longitudinal median line of the sole is determined by the pins 42. Considering a left sole, for example, this lateral position is determined by moving the pins 42 until the rear pin 42 of the right-hand pair engages the sole at one side near the toe, with the forward pin 42 of the left-hand pair engaging the other edge or side of the sole adjacent to the heel end, as shown in Fig. 3. The pins 42 make, as shown, vertical line contact withthe sides of the sole and, hence, contact with limited portions thereof. Right soles of the same size and shape may then be readily positioned for marking without altering the positionof the pins by positioning them against the end gage 50 and v appropriate pins. In other words, a left sole is positioned by the right-hand rear pin and the left-hand front pin and the right sole is positioned bya left-hand rear pin and a right-hand front pin.

b When marking, thesole at the breast-line the gage block52 is placed on the gage plate 50 and the pins 42 are not used to position the sole. The gage block 52 is positioned an appropriate distance behind the mark 60 on the work support in accordance with the size of the soleand the operator merely presents the heel end of the sole to the V-shaped recess 54 in the block 52 and positions the sole laterally. I V

Fixed on the upper face of the work support 30 at each side thereof are two brackets66, 66. Ex tending across the front of the bracket 66 is a rectangular piece of safety glass 68 beneath the lower edge of whichthe soles are pushed on to the work support. These brackets 66 and safety glass I ragodgoai -fli'lfmvagug'lfiitoilpmmnt mea times-mass fifrom' bilngi'flliurtd by thetmlmngitoolllZE'and 'thesglassfitasallows iizbemperatonitoiuseeathahthe solezisrpnoperlyxposltionediagainstithexgagesg iThemarkingttooli carried bysaioeltwmnedmoll 510; extending 'horizontally acrossithezmaizhinerandi isrrotatably :mounted .ini'thezlowerandsmfia'qiaircof arms 12, 3110f eagswinging; lever '14 aizhiclnlsqiiwotedmmpins 16, limited 2 to w uppers rearwardsemls of jlthe Eprevent.undesiredrlaterakmvnmentiofithe :upper ends; of ,the brackets. .fl'heiarmsiflnof theswi n r ing lever M are connected byinearwardly and zdownwandlyextendingzlinksrao, M {to the marking tool lever A 6 --:and .-the; arrangemmt isfisuchf that i whenathe rrnachine l is timitarstoppedgposition the markingeedge of:-theimarking toehlzsis approxi "mately 54; o a ey imm ketser n rr or :the inking roll :10 tandwvhen theg-maehinedsput operation gthe marking toolrfl first .-.moves .away :from =the qwork table to the limit of its movementiin this directioniandithrough therlinks r80. draws= the inking.rollwlimintormomentary ebn- .tact with thez markingeedge of ,the --marking. tool v22, asgshown vin ,full dines in vFig,,-,4j, '1 ,Then, as the marking stool- 22 .iszswung down steward-the work support, theiinkingirolldflns swung by the links flfiawaytfromtthe edgaofi-thezmarking tool --22.
