This invention appertains to marking devices for sheet material, and more particularly to a novel device for marking a desired pattern on a shoe upper section.

In many shoes, it is customary to stitch or punch an ornamental pattern on the shoe upper. To facilitate the making of this pattern by the shoemaker, the desired upper part or parts are marked with the preferred design. Then, too, the shoe upper parts are'often marked to indicate the pointsof sewing of the parts together. It has been proposed to stamp or mark the pattern in ink, or the like, on the upper parts. However, this marking is objectionable, as the same it can. often be detected after the shoe is completed, and cannot be removed without marring the upper.

Therefore, one of the salient objects ofmy invention is the provision of novel means for employing a template having the desired design struck out therefrom, whereby the said design can be impressed in the shoe upper part so that the design'can be readilyseen without the necessity of employing markingmatter.

Another important object of my invention is the provision of a bed plate for receiving the templates with the struck up design, and the shoe upper parts, having novelmeans for holding the .upper parts in place on the templates against movement, with means for striking the upper parts so as to cause the struck up design on the templates to be impressed in the upper parts, the upper holding means being movable under the influence of the strike plate, whereby said holding means will not interfere with the proper operation of the strike plate.

A further object of my invention is the provision of struck up teats of novel form on the template, whereby the design will be effectively impressed in the shoe upper part, the formation of the teats being such as to form a broken dash line on the upper part, which can be readily followed by the shoemaker.

A further object of my invention is the provision of a novel guide for holding the shoe upper parts in proper position on the bed plate, said means embodying spring-pressed pins depressible under influence of the strike-plate.

A further object of my invention is the provision of novel means for adjustably mounting certain of the guide pinson the bed plate, whereby different sizes of shoe upper parts can be received and properly held.

A still further object of my invention is the provision of a marking machine, whereby the template can be used for marking the desired design on the shoe upper parts with marking material, where such marking material is necessary, such as in the working on leathers of an embossed character. 5

A still further object of my invention is to provide an improved marking device of the above character, which will be durable and eflicient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter, more specifically described, claimed, and illustrated in the accompanying drawings in which drawings:-

Figure 1 is a top plan view of my improved marking device, with one of my novel templates disposed on the bed plate of the machine.

Figure 8 is an enlarged fragmentary bottom plan view of the modified form of the template.

Figure 9 is a detail sectional view taken substantially on the line 9-9 of Figure 8, looking in the direction of the arrows.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the 5 letter A generally indicates my improved marking machine. One of the essential features ofthe machine is the bed plate H], which is preferably formed from polished steel. This bed plate has its lower surface provided with spaced, longitudinally extending ribs ll, having openings 12 formed therein adjacent to its opposite ends. The ribs I I are adaptedto rest on a suitable base l3, which can be in the nature of a casting. This base l3 can carry upstanding pins M for reception 5 5 in the openings |2. This prevents movement of the bed plate It! on the casting.

Rigidly secured to the ribs H are inwardly extending, resilient, supporting fingers |5, which support the movable form plate I6. The spring fingers normally urge the form plate up to a raised position in contact with the lower face of the bed plate. Rigidly secured to the form plate are the guide pins ll. These guide pins are slidably mounted in openings I8 formed in the bed plate II]. By this arrangement the guide pins I! can move in a vertical path relative to the bed plate, and when the pins are pressed downwardly, the same carry the form plate therewith. The guide pins H are arranged to conform to the outline of the upper part, which is to be marked, and in the drawings I have shown the pins arranged in such a manner as to receive a pair of companion side upper parts;

Outward movement of the form plate It can be limited by headed studs l9, rigidly connected with the bed plate, and, as shown in Figure 4, the form plate I6 is slidably mounted on the headed studs. The studs also form an efficient means for guiding the form plate during its movement, and if desired additional guide studs 26 can be employed. In conjunction with my novel bed plate I employ novel templates 2|. These templates 2| can be formed from sheet metal, and be shaped to conform to the upper part, which is to be marked. I strike out from the template a series of teats 22 disposed in the desired design. These teats 22 are of a novel configuration, and by referring to Figure it can be seen that the same are of a substantially ellipsoidal shape. This provides means for making an indentation in a shoe upper, which can be easily seen, and a series of teats making a broken dash line on the shoe upper.

After the bed plate has been placed on the casting I3, the template 2| is positioned on the bed plate with its edges in contact with the guide pins Each template is provided with studs 23, which can be inserted in openings 24 formed in the bed plate I0, and in the form plate IS. The upper part, with its upper face lowermost, is placed on the template in engagement with the guide pins H. The upper part is now ready to be marked.

To bring about the desired marking of the upper part, I employ a strike plate 25, and this plate is also preferably formed from polished steel. The strike plate 25 can be of substantially the same size as the bed plate, and must be of sufiicient size to completely cover the templates 2| and the shoe upper parts.

It is essential that means be provided for facilitating the manipulation of the strike plate so that the same can be quickly and forcibly brought into and out of striking contact'with the templates and the bed plate. In the drawings I have illustrated one means of carrying the strike plate, and this means may consist of a movable head 26, which can be in the nature of a casting. This head plate 26 is 4 rockably mounted on a pair of parallel levers 21. The terminals of the parallel levers 21 are pivotally connected respectively to the side edges of the head 26, and to the sides of the casting l3, which extend laterally of the bed plate. The strike plate 25 carries threaded studs 28, which extend through the head 26, and thumb nuts 29 can be threaded on the studs for holding the strike plate in position. Any desired type of justing the pins.

handle 30 can be connected with the head 26 for facilitating the movement thereof.

In operation of the strike plate, the handle 30 is grasped, and the head with the strike plate is swung over and down to the bed plate. The guide pins |'l recede with the downward movement of the strike plate, and the strike plate forcibly engages the templates so that the design will be effectively impressed on the leather. The head 26 with the strike plate can now be returned to its normal position at one side of the bed plate, and the marked upper parts can be removed and new upper parts immediately placed in position,

' after which the head can again be operated;

As heretofore suggested, some leathers are of such a character that indentations cannot be readily seen therein. These leathers are of the crocodileand snake-skin type, and hence this type of leather must be marked with a'marking material, such as ink. To facilitate the marking of embossed leathers an ink pad 3| can be associated with the casting l3 at one side of the bed plate when such'leathers are to be marked. In this instance the templates 2| are removed from the bed plate, and the templates are connected with the head plate. If desired, the strike plate can be left on the head plate, and in this instance both the head plate and the strike plate are provided with short slots 32 for the reception of the studs 23 of the template. By providing the slots 32, the templates can be adjusted within certain limits relative to the upper parts to be marked. After the templates have been adjusted to the desired position, the same can be firmly held in place by means of nuts 33 threaded on the studs 23 into intimate contact with the head 26. The embossed leathers are placed on the top surface of the bed plate, in engagement with the guide pins ll, and the head '26 is swung back and forth. The teats 22 on the template will receive ink from the pad 3|, and this ink will be carried on to the embossed leather parts.

I can provide means for adjusting certain of the guide pins whereby different sizes of upper parts can be received without necessitating the changing of the entire bed plate. In Figures '7 and 8, I have illustrated one preferred way of ad- This adjusting means may comprise an adjusting plate 35 slidably mounted on the lower face of the form plate l6. To slidably mount the adjusting plate 35 on the form plate, the same can be provided with guide slots 36, through which extend guide pins 38. These guide pins 38 can be in the nature of screws, and the screw heads can be countersunk in the top of the bed plate. The bed plate |0 above the adjusting plate 35 is provided with slots 39 for slidably receiving the inner adjustable guide pins, which are indicated by the reference characters H. The adjustable guide pins H are of a special form, and the same also slidably extend through the slots 40 in the form plate, which are of the same character as the slots 39 in the bed plate. The adjusting plate 35 adjacent to its side edges is provided with inclined guide slots 4|, and certain of these guide slots 4| can be provided with laterally extending communicating keyhole slots 42. The lower ends of the adjustable guide pins ll are reduced and provided with heads 43. The heads 43 are inserted through enlarged portions of the keyhole slots 42, and the reduced portions of the slidable guide pin H are then slid into the guide slots 4| in the adjusting plate. By this arrangement, the guide pins are prevented from being displaced from the adjusting plate. After the movable guide pins l1 are mounted on the adjusting plate, this plate is positioned on the form plate, and the guide pins are inserted through the slots 39 and 40. A manipulating handle 44 is formed on the adjusting plate 35, and the same extends outwardly to one side of the bed plate, and the handle can be marked to indicate the different sizes of shoe upper parts, so as to facilitate the moving back and forth of the adjusting plate. One edge of the handle can be provided with a plurality of notches 45, and a resilient tongue 46 can be carried by the form plate for engaging in said notches to hold the adjustable plate 35 in its desired position. When it is desired to change the position of the movable guide pins H, the adjusting plate is slid in or out, as the case may be. The walls of the inclined slots 4| riding against the pins will force the pins inwardly or outwardly in their guide slots 4|, and thus dispose the pins in their desired position.
