MARKING: IttEAQl-IINE.

Application filed May 3,

This invention relates to improvements in marking or stamping machines, and particularly to a machine of the character specified, designed for marking curved or irregular surfaces, for example, brush handles, although it will be evident from a considera tion of the following specification that my invention may be used for marl-:ing articles or objects of various kinds made from differ ent materials.

The prime object of the present invention is to provide a simple and efficient machine of the character specified above, in which a die or marking means is passed. over the surface of the article to be marked with suflicient pressure to properly mark the desired surface and, at the same time, so mounted to permit of the marking of curved or irregular surfaces. Further objects of the invention are to provide new and improved means for moving the die into and out of operative position, and to effect a marking in an expeditious manner; and to provide common cooperating means for effecting a movement of the die to operative position and the travel of the marking means over the article to be marked.

Other objects and advantages will be hereinafter referred to or become apparent from a consideration of the following description taken in connection with the drawings.

In the accompanying drawings, which illustrate an application of my invention:

Fig. l is a side elevational view of a marking machine embodying my invention;

Fig. 2 is a detail part ,elevational and a part sectional view taken on the line ill-d1 of Fig. 1;

Fig. 3 is a detail top plan view, particularly showing the actuating linkage employed for reciprocating a roller die carrier,

Fig. 4: is a front elevation of the machine; and

Fig. 5 is afliagmentary side elevational View, showing the position of certain parts during the marking operation.

As illustrated and as preferred, my machine includes a suitable base 5 having at one end thereof a standard or bearing 6, the latter being designed to have pivotally mounted thereon a movable arm 7. Movable member or rocker arm 7, as shown, comprises a curved main part having curved contacting edge portions or cam surfaces 8 and 9 and is provided at one end thereof with guides 10 designed to member or 192$. Serial No. 274,7t3d.

receive and support a reciprocating diecarrier 11, the latter having flanges 12 thereon for engagement with the guides 10. blecuredto the outer end of the carrier, I provide a depending forked member 13, said member being fastened to the carrier by a screw bolt 14; and designed to support a roller die 15 of any suitable kind, and upon which the characters to be marked on the article are carried.

it will be understood that my invention contemplates moving the die or marker into and out of operative positions, relatively to the article to be marked, which is retained in a fixed position; and, further, to cause the marker to be moved over the surface to be marked, and for this purpose the mov able arm 7 and the carrier 11 are connected with means for manipulating and actuating the said members 7 and 11.

To this end, member 11 is slotted as at 1-6 to receive the end of a link 17 constitutingan element in the linkage employed, and is tted at 1'? to receive a pin 18 carried on a portion of the actuating means which l have designated generally by the numeral 19. r v

The actuating mechanism, as illustrated, includes an upwardly extending movable arm or member 20, a transversely extending shaft 21 having bearings in supports E21 attached to or formed integral with the base 5, to which the said member is fixedly secured by a pin a, and by which the arm 20 is adapted to be moved by revolving the shaft; a pivotally mounted member 22 disposed in a cutaway portion of the movable arm member 20 and mounted on the pin 18; saidmember 22 carries a contact roller adapted for rolling contact with the curved or cam surfaces 8 and 9 of the arm .7 during the operation of the machine, as

will be more fully hereinafter described.

Attention is called to the tapered lower end 214: of member 22 and also to the fact that this inclined or tapered face is positioned on an inclined bearing face 25 of member 20 and that the said inclined faces are designed to be normally held in contact by means of a tension spring 26.

Designed to cooperate with member 22 to control its movement, I provide an adjustable stop member 27 adapted to he secured to the rocker arm 7 by means of screws 28. lhe said stop 27 carries a spring pressed tripping trigger 29 having a small leaf spring 30; Trigger 29 is positioned to engage a plate 31 mounted on the member 22.

Located intermediate the ends of the base are a pair of vertically extending guide members 32, and at one end of the base it is w cut out to form a transversely extending members have tongues or flanges 40 having sliding engagement with retaining plates 41 secured to the base.

42 designates an operating lever for rotating or partially revolving the

shaft

21, and 43 indicates a-counter-balanced weight employed in connection with the shaft 21.

For the purpose of imposing the desired weight or pressure on to the marking means, the arm 7 is connected with a weighted lever arm 45 fulcrumed in bearing 46 by means of links or connecting members 47 connected to arm 7 at their upper ends by a pin 48. These links extend downwardly from arm 7 through an opening 49 of the baseand pivotally engage the lever 45, as at 50. By providing a proper weight 51, the desired pressure of the die roller 15 on the article,

I such, for example, as the handle B of a brushA, may be obtained.

It. willbe apparent from the above description that a movement of the shaft 21 and the actuating means, generally designated 19, may be effected by a movement of dotted lines, Fig; 1. During this movement,

it will be apparent that the pin 18 will be moved from one'end of the slot 1'7 to the other end of said slot formed in the link 17. During this last mentioned movement, member 22 is, by means of the stop mechanlsm including the trigger 29, tilted or rotated in a counter-clockwise direction, owing to'the fact that the said trigger 29 is in locked position with the plate 31 of said member 22. It will be understood that further movement of the handle 42 in the I said direction will disengage the trigger 29 and plate 31 of member 22, thus permitting .the arm 7 and its die roller 15 to be low- -ered until the die roller comes intocontact with the brush handle B. This tilting movement of member 22 is against the tension After the die roller 15 is lowered into operative position upon the brush handle, the desired pressure or weight to effectively mark the article is obtained by the weighted fulcrumed lever 45 and the connections interposed between said lever and the arm 7.

It will be noted that the downward movement of the arm 7 and the die roller is effected by means of the weight applied thereto by the weighted lever -15, and that the limit of the marking movement will be reached when the contacting roller :23 of the member 22 reaches the point of juncture between the differently curved cam surfaces 8 and 9, as indicated at 52. After the roller 23 passes the said point 52, it will be understood that the spring 26 will snap the member 22 into its normal position, as shown by the dotted lines, Fig. 1, and that the forward end of the rocker arm 7, together with the die carrier mounted thereon and the die roller, may be elevated from the brush, due to the action of the weight 43. During this forward movement of the operating lever 42, it will be seen that the die roller is lowered into operative position on the article to be marked, and will have traveled over the curved or irregular surface and then raised therefrom. It will also be understood that by adjusting the stop member 27 upon the arm 7 the desired distance of travel of the die roller upon the article to be marked may be effected, and that, upon the return movement of the operating lever, the parts of the actuating mechanism will assume the position shown in Fig. 1, with the movable member 22 again locked by the trigger of the stop mechanism.

To facilitate production, a mold may be clamped between the vise members of the same, said mold shaped to receive the brush handle or other article, and hence it will not be necessary to adjust the vise members 'to article-engaging position each time an article is marked.
