" -numbering machine whereina handle is depressed so as to permit-the depressing of a system of dials by hand in a small portable frame. 7

It is the object of my invention toprovide a bodily movabledial system consisting of aplurality of dials in connection with which I provide means for locking and aligningthe dials together when in use, and permitting the changing of any dial or: dials by a releasing of the dial aligning members,there being one for eachdial. I provide an inkingdevice which, during the depression of the dial system, swings an inkingpad into contact with the dial and then moves the inking pad out of the way, and I providemeans whereby the pressure of the inking device against the dial can be controlled, so that heavy marking or light marking can be accomplished. Certain features of my mechanism are novel and useful irrespective of the type'of printing or marking member that is employed.

My device is very easily assembled and disassembled, and consists of asmall number of parts, and is easy to operate and keep in F repair.

I accomplish my objects by that certain construction and arrangement of parts of which atypical example is illustrated and described, and the novelty of which is set forth in the appended claims.

Figure 16 is an enlarged section taken on the line 16-16 of Figure 15. V

The structure is formed of a U-sh'apedJr-vE frame'l having a base 2 which is applied over the article to be marked, whichhas'an opening 2a through which the desired dial face projects in marking a piece'of fabric or the like. A tube 4 is securedto thetopse of the U-shaped frame through which tube passes an operating rod 5 of the-machine. The upper end of I the operating rod .is equipped with a handle 6 whichtelescopes over the tub-e4, and a spring7 is housed within the tube 4 and the handle 6 and serves to press the handle upwardly to theposition shown in Figure 3.

Within the main U-shaped frame is the dial carrying frame shown in Figures 14 and 1-90 15, which consists of a U-shapedpiece having side plates 8-8 and atop portion 9.. The upper portion of this frame at the rear is closed by a transverse wall 10. The side plates have projections 11 whichserve1tou95 mount a pin 13 which pivotally supports a series of pawls 14. The pawls have handles 15 whereby they are operated, and each pawl has a spring 16 connected so as to draw the lower end of the pawls inwardly of'the mech-g ,100

anism, these springs 16' being connected to a pin 17 extending across the upper end of the frame 8. Secured on one side 8 of the dial carrying frame is a stud 18 which slides in a groove 19 inthe frame 1. The other side of the frame 1 has a vertically extending slot 20 through which the dial shaft projects.

The dial shaft shown in detail in Figure 8' has a slotted shaft portion 21, a collar 22 which engages the inner face of the frame 1, and a head 23 which engages the outer face of the frame 1 (Figure 6). The shaft 21 passes through and is supported in the apertures 24 in the sliding dial frame 8. I Set alternately on the shaft 21 between thesides of the sliding dial frame are numbering or marking wheels or dials 25 and friction washers 26. The friction washers have internal keys 27 which engage'the grooves or splines 28 in the dial shaft.- The dials are so located that they are engaged each by one of the pawls 14, and the type faces 29 of the dials are considerably projected from the main body of the dials so as to act as teeth with spaces 30 between them in which the pawls engage. V

As so far described, it is evident that if I the operator pushes downwardly on the handle 6 the frame 8, 9, carrying the dials and pawls will be depressed in theframe 1 and a selected type face on the dials will be impressed upon the article to be marked. Upon the release of the handle the dials and their frame will move upwardly to starting position. To change any dial its pawl its elevated by pressing inwardly on its handle 15 and the head 23 of the dial shaft revolved, which will frictionally move the selected dial around. When the dial has been brought to the desired position for marking the pawl is released and will hold this dial against further movement while other dials are being adjusted, and in addition will line up the adjusted dial with the remainder of the dials.

The inking mecha/n ism Theinking mechanism is mounted on a flanged plate 31 (see Figures 11 and12),

which plate has ears 32 whereby it is secured by pivot screws 33 in the upper end of the U-shaped frame 1. A leafed spring 34 secured to the top of the frame 1 engages the plate 31 and holds it in position against the side of the U-shaped frame 1, from which guideway formed by the part 35, the plate 38 being backed by the plate 39 that lies in a slot in the plate 31. These parts'are best shown in Figure 13. A spring 40 secured to a stud 41 passing through the plate assembly 36, 38, and 39, serves to hold a rack bar in its upper position.

A shaft 42 mounted in projecting arms 43 of the flanged plate 31 is fixedly secured to a yoke 44. The yoke 44 carries an ink pad 45 which is rocked into engagement with the descending dials when the shaft 42 is rocked. A sector gear 46 at the center of the shaft 42 is engaged by the rack bar so that when the rack bar descends it will rock the shaft 42. V

Secured on the inner face of the plate 31 is a slanting finger 47 which strikes the rear edge of the dial frame resulting in rocking the plate 31 and the parts assembled thereon entirely out of the way of the descending dial system.

In order to push downwardly on the rack bar, means are provided on the back plate" 10 of the sliding dial frame for engaging the upper end of the sliding rack bar assembly. To this end the members 38 and 39 terminate flush with each other as at 48,

where they are engaged by a spring dog which will now be described.

Referring to Figures 14, 15 and 16, I secure to the back of the dial frame a casting having slotted lugs 49-49 which are interspaced to act as a guide for the bevel edged dog 50. This dog is mounted on a bolt which slides in a boss 51 of the casting and is equipped with nuts 52. A spring53 lying between the dog and the boss tends to push the dog outwardly. By turning down the nuts 52 the position of the dog and the spring tension urging it outwardly can be adjusted. Also, any desired spring can be employed and the position oft-he dog 50 regulated by means of the nuts 52. In order to guide the dog firmly, a pair of pins 54 are inserted laterally into it, and these pins slide in the slot-ted lugs 49.

The dog engages the end 48 of the rack bar mounting so that as the dial system is depressed the dog will push downwardly on the rack bar, thus causing the inking pad to swing into engagement with the descending dial. When the engagement is established and the operator continues to press down onthe dial system, the dog 50 will be forced out of the way, thus permitting the rack bar to move upwardly and by means of the rack and gear," causing the inking pad to be swung out of the way of the dials. is accomplished the finger 45 contacts with the dial frame which move'sfthe entire inking device out of the way as the marking impression is made.

By adjusting the tension of the spring 53, and adjusting the position of the dog 50, the force with which the'inking pad is brought up against the dial can be regulated as is evidenced.

Upon spring return of the marking dials" When th to their original position, the dog will, again engage over the end 48fof the rack bar mounting and the machine will be ready for another operation.

In practice the machine can be operated as rapidly as the operator can press down and release the handle 6. The adjustment of the dials is simple and easy, and theiinking pad is normally out of contact with the dials instead of being in contact with them, as in the usual time stamping or numbering machine. The locking device for the marking dials serves to keep them in alignment,and the friction method of adjusting the dals is such that very little effort is required.
