TILSON 2,329,493 I MARKING MACHINE Filed Oct. 2, 1940 3 Sheets-Sheet 3 The primary object the provision of an ink supply means by which the dieis supplied with ink, such means including a die conta'cting element movable intermittently by and in timed relation tothe carrymg'plat en Another object oi the invention resides in the of this mvention resides'fin the reciprocation of structure of the supporting means for the die carrying platen and the connection between such supporting means and the die contactingelement of the ink supply means.

These and other, objects of the invention will appear" from a consideration of the following description and of the drawings which form a part thereof and in which Figs. 1 and 2 together illustrate in side elevati-on a machine embodying this invention;

designs, guide lines and the like upon sections of ,7

shoe uppers, and comprises briefly three units,

viz., a bed 2B on which the sectionsof the shoe 4 uppers are supported when being so imprinted, a platen 3!] by which the marking die 40 is carried, and an ink supply means 50. 'Iheseunits are supported by a rectangular base frame which i rests upon a table I 2. g

The bed 20, here shown as anintegral part of the frame I I; carries a mat 2| which is positioned on the bed by pins 22 which project upwardly from the bed through apertures in the mat, and

by a leaf 23 fixed to the bed and projecting out- 5 0 wardly therefrom. On edge of the mat abuts an edge of the leaf and straps 24 pivotally mountedon the leaf extend over the mat and prevent any I inadvertent raising thereof. A gauge 25 attached to the mat 2| in any desired manner as by cement 55 N. Hr, .assignor of .colf poration- 0f. N.ew I

Springs 31 attached at one end'to' the arms 33 of the rearward pair of levers and at therother end to pins 38 on the brackets32supporting the forward pair of levers normally .hold the levers vertical as shown in Fig. 1. The arms 33 and links 34 insure a uniform movement of the levers 3|. A marking die 40usually of metal is attached to the underside of the platen 30 by any suitable meansas, for example, by magnets 4|.

At thejforward end of the: platen 30is mounted a handle 42. Fixed tothe cross shaft 36 which carries the rear levers 3| is a sheave 43 about which is wound one end of a cable 44 and to which that end is secured (see Fig. 5); A bell crank treadle 45 is pivoted upon a'stud 46 carried by a bracket 41 attached to the under side of the table l2.

The other end of the cable 44 is secured to the upper end of the treadle 45 and the lower end of the treadle is provided with a foot plate 48. The platen 30 can obviously be reciprocated by means of the handle 42 or the foot plate 48. i

The ink supply means 50 includes a table 5| rigidly supported'on legs 52 carried by the base frame I I and an endless belt 53 movable over the table and carried by rollers 54 and 55 at the front and rear edges of the table and a roller 56 supported below the table. Ink is supplied to the belt 53 from a pan 51 by a fountain roll 58. The roll 58; is carried byspring arms 59 and yieldably held in contactwith the belt 53 .as it passesunder the roller 56.

The roller 55 is supported-at its ends by hangers 60 adjustable in length toper'mit varying the height of the roller 56 as desired. The roller 55 may also be adjusted, beingcarried in arms 6| secured to the under side of the table 5| by set screws 62 which extendthrough slots 63 in the I table.

of the roller 55 is a sheave 65 to which one end of a cable 66 is secured and about which that end is Wound. A coiled spring 61 is secured at one end to one of the arms 6| and at the other end to thesheave and holds the latter normally at rest. A ratchet wheel 68-"is "carrie'dby the roller 55 and its teeth are engaged by a pawl 69 on the sheave 65 held by a spring'lll in contact with the teeth. The other end of the cable-J5 f1. 66 is secured to a pin H carried by oneofthe.
