This invention relates to. marking machines for making impressions -upon leather and other materials for ornamental purposes, or

to indicate the outlines for the guidance of subsequentoperations, or for any other purpose desired. v

An object of the invention is toprovide a machine for the purpose stated comprising means for supporting the material or ,articles to be marked in diiierent'positions orat different altitudes above a base, and a manipu. lative die supporting device movable from position to receive a markin'gsubstance, such as ink, to a position to press upon the material to be marked and make an impression thereon with vthe'niarkng substance.

Another object of the invention is to prov vide a marking machine equipped wlth means for properly supporting, locating and holding fitted shoe uppers in a position to receive the impressions from`the marking device.

Another object of the invention is to provide a machine'capable of operation upon fitted shoe uppers or upon flat work, jas de-- slred.

Other objects will appear from the following description, reference being made to the accompanying drawings in which,

45 Fig. 6 is a perspective view of the work support shown in Fig. 2 which is designed and adapted yfor usein working upon fitted shoe uppers and similar work.

The supporting frame 1 of the machine 5 may, if desired, be in connection with legs is supported above the plate 1.

2 in order to support the frame at the proper height for convenient operation ofthe machine. Upon the u per or rear portion of the frame 'a box-likemember 3 is mounted, the 55 horizontal upper end wall 4 of the part 3 being enclosed within an upwardly'extended marginal ange 5. The bottom wall 4 and 'the surrounding flange 5 forms a pan to contain a pad 6 that may be saturated with any 60 lil-uid marking substance, such asink. The

.part3' may be rigidly secured to the'frame' 1 b'ybolts 7 extending through arms 8 projecting from said frame 1 and through arms 9 .pro'ecting laterally -from the .part 3.

A a'selO is mounted on the front of the frame 1 at the rontside of the part 3 and lhas its upper surface in a plane lower than the pad 6. The base 10 is rigidly attached to theframe 1 by bolts 11 passing through ears 70 12 projecting from the frame 1 and through ears 13 projecting laterally from the base 10. This base 10- is designed and adapted to receive interchangeable work supporting gages of dii'erent es and designs. One such 75 work supporting gage is shown in Figs. 1 and 2 an is designed specially to support and position or gage shoe uppers and the like for operation of the marking .mechanisnL This work supporting gage comprises a plate 14 having holes therethrough to receive dowel pins 15 rigid with and projecting upwardly from the base 1. A horizontal gage late 16 e gage plate 16 has its rear edge detachably secured 85 to a block 17 by screws 17, which block 17 is rlgid with the plate 14. The front edge of the plate 16 bears upon' a post 18 which isin rigid .connection with the plate 14. The post 18 is a relatively small supporting ele-f 90 ment. This leaves a portions of the plate .16 laterally fromthe post 18 and in v:Eront' of the block 17 spaced so that portions of the fitted shoe upper or other work may enter said spaceswhile otherv portions ofthe shoe upper or other work are properly located upon the support 16 by gage elements. 19. shown, the gage elements 19 are in the form` of pins which are designed and adapted to project through holes or' openings in the work. But, it is obvious that any appropriate type of gage elements may be' used and that the invention is not restricted in thisrespect.

The die carrier 20has its rear edge pivoted to theupper ends of arms 21, the lower ends of which are attached to a shaft 22 mounted for rocking` movements in the walls of the part 13.- The front edge of the die carrier 20 is pivoted to the upper ends of arms 23, the lower ends of said arms 23 being pivotedto they upper ends of projections 24 which are rigid with and extend upwardly from the frame 1 at the sides of the base 10 and considerably to the front of the part 3.

The under side of the die carrier is formed with a recess 25 (Fig. 4) designed and adapted to receive projections 26 from the die plate 27. A clamping device 28 is rigid'with the lower end of a stem 29 mounted for turning movements in the die carrier 2O and being operative to obtain clamping engagement with and to release the projections 26. ,The stem 29 projects upwardly through the die carrier 20 vand is rigidly secured to a handle 30 above said die carrier, which handle is operative to turn the spindle 29 to obtain clamping engagement with the ears 26 or to release said ears, as desired. A pin 31 proj ecting from the die carrier into a notch 32 in a plate 33 that is rigid with the lower end of the handle 30 limits extent of turning movement of said handle but permits suiiicient .turning movement to obtain engagement with and to release the projections 26. In order to cooperate with the clamping devices described to prevent turning movement of the plate 27 with respect to the die carrier 20 said plate 27 is provided with one or more projections 34 spaced laterally from the projections 26 and designed and arranged to engage in holes 35 in the die carrier. Obviously, when the projection or projections 34 are engaged in the 'holes 35 and when the clamping device 28 is engaged with the projections 26 the plate 27 will be held clamped against the under side of the die carrier 2O and will be held from turning. The underside of the plate 27 supports a markingdie 36. When the die car- .rier 20 is swung tothe rear the marking die 36 contacts with and receives marking substance from the pad 6 so that when said die carrier is swung forwardly and downwardly the design of the die will be impressed upon the material, such as a shoe upper that is positioned upon the plate 6 by the gages 19- That is to say, a iitted upper can be conveniently applied to these gages because of the novel way in which the plate 16 is mounted and supported in spaced relationship so that the fitted upper may be draped about said plate. In this manner that portion of the upper which-is to be marked with a design is above the plate and other portions draped down at the ends of the plate 16 and under said plate.`

and interchangeable, such plates bearing different designs and arrangements of gages 19 may be used, as desired. And, since the plates 27 are removable and interchangeable, different designs of marking dies may be used. This is a highly important feature of this invention, as my machine is designed and adapted for a muc-h wider range of usethan machines in which these improvements do not exist.

In the same instances it may be desired to make impressions or designsupon or in flat Work, such as flat pieces of leather. It is desirable, of course, that fiat work be supported at the same height as tted uppers or the like so that the extent of forward movement of the die carrier will be approximately the same for all classes of work. In order to support fiat work at'the same height as the supporti-ng plate 16 I provide a removable platen 37, the vertical `thickness of which is the same as the vertical distance from the under side of the plate 14 to the upper side of the plate 16. Thus when the platen 37 is placed upon the machine the upper side of said platen is in the same -plane in which the upper side of the plate 16 is located when the equipment shown in Figs. 1 and 2 is used. The under side of the platen 37 is provided with holes to receive the dowel pins 15 and the side edges of said platen are provided with extended handles 38 to facilitate and expedite placement and removal of 'the platen. From the upper side of the platen 37 dowel pins 39 project. And the gage plates 40, having therein gages 41 are provided with holes to receive the dowel pins 39. Thus when the dowel pins 39 are projected through the holesin the gage plates 40 the said gage plates are necessarily thereby positioned so that the' gages 41 are in position properly to guide and gage the location of the Hat work upon the plates 40. Thus the gages 41 locate and position the work` for proper operation of the die carrier That is to s ay, backward and forward operation of the die carrier will result in making proper impressions, designs, outlines. or the like upon (not shown). In order to move the die car- I rier to and retain said die carrier in an appropriate starting position I provide springs 44 having connections 45 with a part of the member 3 and connections 46 with the shaft 22. The power and tension of this spring is utilized to support the die carrier 20 approximately vin the position shown in Fig. 2 when the machine is idle. That is to 'sa-these springs support the die carrier above the gage devices at the front of the ,machine and also in a position in which the die is out of contact with the pad 6. In this position the die carrier is intermediate therpad 6 and the position of the work to be o erated upon.

From the foregomgit will be seen that I` .with e ual satisfaction y use of the equipment s own in Figs. 1 and 2 will operate upon fitted uppers of shoes or other workof that character without creasin the material.

The feature of interchangeab' ity of the dies and ofthe gage and work supports is of a high degree of `importance and these improvements are claimed broadly in this machine..
