This invention relates to pattern marking machines for use in shoe factories, and more particularly to the construction of the platens of such machines.

Pattern marking machines for shoes, as is well known to those familiar with the art, usually comprise a base mounting a template card upon which the shoe element to be marked is placed, a movable printing head adapted for the interchangeable reception of marking dies, and a means for inking the die.

It is oftenessential in marking shoe elements, particularly quarters, Vamps and tips, that the pattern applied be differently placed upon similar elements of different size shoes in order that the shoe stock in its completed state may have an appearance of proportion. The usual shoemarking machine provides no means of adjustment save possibly a rough adjustment of the die carried by the printing head, and this adjustment is both diflicult to make and impossible of any great variation. It is often necessary that the pattern be displaced at one end of the section While held in a corresponding position at its opposite end, in various sizes. In marking a changed size, it is often necessary that the marking be shifted both longitudinally and transversely. In corresponding markings for rights and lefts it is essential that the markings be correspondingly placed.

An important object of the present invention is the provision ,of a platen which is so constructed that adjustments made for varying sizes and types may be accurately determined, and these adjustments made with a minimum of time loss and effort.

A further object of the invention is the production of an apparatus of this character which may be readily produced and which will be durable and efficient in service.

'These and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration. I have shown a preferred embodiment of my invention and wherein:

Fig. 1 is a plan view of a shoe-marking machine constructed in accordance With my invention showing one adjustment of the platen;

Fig. 2 is a section on line 22 of Fig. 1;

Fig. 3 is a plan View of the platen removed;

Fig.4 is a section on line 44 of Fig. 3;

Fig. 5 is a section on line 55 of Fig. 3;

Fig. 6 is a combined perspective of the several parts forming the platen;

Figs. '7 and '8 are bottom perspectives of two different forms of platen face; and

Fig. 9 is a perspective of a template.

Referring now more particularly to the drawings, the numeral I generally designates a platen bed; i l, a printing head; I2, a die carried thereby; and I3, an inking device for the head. Seated upon the platen bed is a platen comprising a base i4 having upstanding side guides I5 and having disposed within a longitudinal slot l6 formed 10 therein a block i1 adjustable through a screw H3. The block I! is adapted for attachment to a sub-base l9 slidable between the side guides l5 and provided with upstanding end guides 20. The sub-base 59 has a block 2! slidable in a transverse slot 22 formed therein and adjustable by means of a screw 23. This block 2! is, in turn, adapted for attachment to a plate 24 having in its upper surfacea longitudinally-extending groove 25. A slot opens through the bottom of this groove, as indicated at 26 and within this slot is disposed an adjustable block 2'! mounting anangular shifting head 28 which, upon adjustment of the block, moves transversely of plate 24 and grooves 25, this adjustment being effected by a screw 29.

Mounted in the groove 25 is a slide 30 having an angularly disposed slot 3| forv the reception of the angular shifting head 28. The slide 30 fits the groove 25 and it will be obvious that ad- 30 justment of the head 28 will result in longitudinal shifting of slide 30. This slide has at opposite ends thereof pairs of divergent angular slots 32 and 33. The plate 24 is provided with a pair of spaced pins 34 disposed at one end 35 thereof, and at common distances from the center of the groove 25. 1

Superimposed upon the plate 24 is a divided platen face 35 which may assume a variety of interchangeably usable forms. In each of Figs. '7 and 8, the platen face is divided, the sections 36 in Fig. '7 having at opposite ends of adjacent sides thereof fixed angular blocks 31 which are adapted to engage in the pairs of slots 32 and 33 respectively. The inner corner members of the sections 36 are notched as at 38 so that the plates may partake of transverse movement without engaging the pins 34. It will be obvious that by reason of engagement of these angular blocks in the slots 32 and 33, the sections 36 will be separated or drawn together, dependent upon the direction of longitudinal movement of the slide 30.

The platen face of Fig. 8 has a single set of blocks 39 at the rear end thereof, one block being arranged upon each plate and the blocks being shiftable about pivots 40. These sections 36a have openings 4| therein for the reception of the pins 34 which act as pivots about which the sections 36a may swing (see Fig. 1). Blocks 39 engaging in the slots 33 will cause the rear ends of the sections to separate or be drawn together as the slide 30 is shifted longitudinally.

The upper surfaces of the sections of the platen face have upstanding pins 42 adapted to hold templates 43. As in the case of the platen face, the templates may assume a Variety of forms, two being herein illustrated, although it will be understood that a template must be provided for each different form of upper section which is to be marked, such templates having gauges 44 against which the piece to be marked may be placed. The template illustrated in Figs. 3 and 6 is split, and is of the type employed when two similar sections, right and left, are to be simultaneously marked. The template has, along one marginal edge, a series of size graduations indicated at 45 and adapted for co-action with an indicator pointer 46 carried by the sub-base I9, and along a second marginal edge a series of size graduations 4'! adapted for coaction with a pointer 48 carried by the base I4. This latter pointer, in the present instance, is illustrated as yieldably mounted in order to accommodate oscillation or separation of the platen faces. The template of Fig. 9 is a unitary sheet adapted to engage the pins of both platen faces and is utilized in marking of larger pieces. The gauge marks 41 are provided on this type of template although under some circumstances where a single piece is being marked both gauge marks 45 and 41 may be employed.

It will be obvious from the foregoing that the platen faces may be simultaneously shifted longitudinally or transversely, may be moved toward or away from one another, and in special cases may be oscillated to vary the angle of printing upon the varying sizes. Each of these movements may be employed independently of the other, and by use of templates having proper gauge marks all adjustments may be rapidly and accurately made. Since variation of the position and angle of the piece to be marked with relation to the platen bed will permit placing the markings upon the piece at any desired point, it will be obvious that necessity for a large number of templates such as is ordinarily employed may be avoided. This means not only that the cost of marking is reduced to a minimum but likewise that the operations of marking where a number of different sizes are being produced are much simplified and expedited.

The construction is obviously capable of considerable modification without in any manner departing from the spirit of my invention and I, accordingly, do not wish to be understood as limiting myself thereto except as hereinafter claimed.
