MARKING-MACHINE.

Specification of Letters Patent. Patented NOV. 30, 1920.

Application filed October 12, 1918. Serial No. 257,910.

T 0 all whom it may concern:

Be it known that I, EDWIN W. SMITH, a citizen of the United States, residin at Beverly, in the county of Essex and btate of Massachusetts, have invented certain Improvements in Marking-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

The present invention relates to machines for marking various objects, as portions of shoe uppers, and has to do more particularly with apparatus in which marking members may be set in various positions to produce different characters.

In such machines the usual expedient is to employ a single setting instrumentality which is successively brought into cooperation with all the marking members which are to be set. This time-consuming process is avoided by my invention, which provides means simultaneously movable into cooperation with different marking members for the independent setting thereof. By this arrangement, plural members may be simultaneously brought to the desired position with considerable economy of time. As illustrated, the setting means, while capable of actuation independently in the setting movement, are movable together in the selection of the marking members. Preferably I arrange members constituting the setting means oppositely, there being groups of these opposite members, appearing as alined concentric sleeves, each sleeve having a projection arranged to enter recesses in the series of marking disks to be set. The connection between the opposite setting sleeves, which causes their travel together, is shown as consisting of a rod passing through them, and also as a rod movable in a support and being joined to the sleeves. I prefer to so arrange the setting members that they normally operate on themore fre quently set marking members. There is illustrated herein a series of marking members having less frequently set members interposed between those more frequently set, with these and the setting means spaced to permit the latter to be in normally operative relation to the more frequentlv used marking members. Then, when necessary, by moving the setting members through a space equal to the width of the interposed markmg members only, the entire setting means may be brought.v into cooperation with the less frequently set members. To guide the operator in setting the marking'members, I have shown indicating means for detervmining the position of each of the setting members.

A single one of the several forms which my invention may assume is illustrated in" the accompanying drawing. Here,

Figure l is a side elevation of a marking machine having my invention applied thereto;

Fig. 2 is a partial front elevation looking from the left in Fig. 1, with portions in vertical section;

Fig. 3 is a vertical section on the line 33 of Fig. 2; and

Fig. 4 is a detail in front elevation of the index member for the setting means.

In a frame 10 is supported for oscillation toward and from a work-support 12, a marking head 14, preferably under the influence of suitable mechanism driven by power applied to a pulley 16. At the forward extremity of the head betweenseparated supporting walls 18, 18 is mounted a series of marking members 20. These marking members are shown in the form of disks rotatable about a tubular spindle 22 fixed at the lower portion of the forward end of arranged for stamping parts of shoe uppers,

we have on the first two disks at the right.

tens and unit size designations, followed by the half-size mark disk, then two disks bearing width symbols, after which are two disks for match marks, and finally six disks with series of digits for the case numbers.

At least one tooth on each disk, as indicated at 28 in Fig. 3, is shorter than the associated teeth to permit the disk to be set to make no impression. Heat may be supplied to the disks by some such device as an electrical unit 30 situated within the spindle 22.

Above the marking disks appear setting disks 32, one for each of the disks 20, arranged between the walls 18, 18 and having alined central openings through which pass the setting means for manipulation by the the setting means consists of members arranged in opposite groups of two each. For these members I prefer to employ tubular shafts or sleeves, there being two concentric sleeves in each group, an inner 34 and an outer 36. The outer sleeves are journaled in the walls 18, and through the inner passes a rod or shaft 38 holding the groups together. A spacing washer 40 surrounds the rod 38 between the ends of the sleeves 34, its width being preferably equal to that of two of the setting disks. At the inner extremity of each of the sleeves 34 is a flange 42 which is equal in diameter to the outside of the sleeves 36. Upon the sleeves 36, the flanges 42 and the washer 40, the disks 32 are arranged to turn. They are normally held in the angular position to which they are set, by spring fingers 44 fixed upon a bar 46 bridging the space between the walls 18, said fingers having enlarged end portions 48 for entering the spaces between the teeth. Upon the inner end of each sleeve 36 and upon each of the flanges 42 is a peripheral projection 50. These projections are movable by the longitudinal travel of the setting sleeves through a series of re cesses 52 connected with the central openings of the disks 32, these corresponding in number and position to teeth 54 projecting from the disks 32 similarly to the teeth 24 of the disks 20 and meshing therewith. The length of the sleeves 34 and 36 is such as to permit the movement of the projections 50 into any of the recesses 52, and fixed upon their outer ends are hand wheels 56, one for each sleeve, the diameter of the inner pair of wheels being preferably greater than the outer pair to permit the operator to manipulate conveniently the separate setting sleeves. The hand wheels are held against shoulders upon the sleeves by screws 58 threaded into the ends of the rod 38 and bearing against the outer pair of wheels. Vhen the sleeves are rotated, the projections 50, by their engagement with the recesses 52 which they occupy, turn the corresponding disks 32, and through the intermeshing teeth 24 and 54 set the marking disks 20.

In addition to the rod 38, the opposite groups 0]": setting sleeves are connected by a rod 60 passing through alined openings in upward extensions 62 of the marking head. This rod is joined to the sleeves 36 by arms 64 surrounding said sleeves and bearing against shoulders upon them, the opposite or upper ends of the arms being secured to the rod'by nuts 66. Fixed to the rod 60 is av me be 6 having an in a ing point for each of the sleeve projections 50 and in vertical alinement therewith. The ends of. the teeth 54 preferably bear index characters 72 corresponding to the dies upon the teeth 24. The parts are so related that when a character 72 is beneath the corresponding index point 70, the like die upon a tooth 24 will be in marking position.

I prefer to have the setting projections of the sleeves normally within the recesses of the disks bearing the unit size designations, the half-size symbols, and those for the match marks. These characters in marking shoe uppers are more or less frequently changed during the stamping of the shoes which are to make up a case. The width number, however, customarily remains the same for the entire case, and the case number, of course, does not change until the work for a new case is to be stamped. With the setting means in this position, the operator can, by manipulating a hand wheel at either side of the head, simultaneously turn the corresponding disks, by the engagement of the sleeve projections with the recesses 52, to bring any desired character thereon into marking position, and can readily shift the grasp to the other pair of wheels to set the disks which these control. If the tens digit also is to enter into the size mark, the movement of the setting means as a whole, by sliding the sleeves and connecting members together to the right in the head through the width of a single marking disk, renders this possible. hen the case is finished, bodily movement of the setting means to the left through the width of two marking disks from the normal position alines the setting projections with the disks bearing the width designations and the first two disks of case numerals, so that the operator may adjust the disks for the width of shoes of this case and set its two highest numerals. $uccessive movements to the left permit the setting of the remaining case numerals, whereupon the setting means may be restored to its normal position.

Having thus described my invention. what I claim as new and desire to secure by Letters Patent of the United States is:
