, brushes,and has for its object particularly,

although not exclusively, the vprovision of improved automatic mechanism for feeding and carrying the brushes into positiontobe operated upon, as by means of stamping mechanism whichin the present instance stamps the lettering on the handles of the brushes. `f

As al further object of"l the invention the machine is provided with an intermittently rotatable feed disk or plate which is parto-f va. Geneva` motion,'this diskliaving an intermittent rotary movement or step` by step movement imparted to it"throilgijhy a driving member forming the other part of the Geneva motion. The feed disk' also constitutes a holder forthebrush handl'esfand carries them successively into a position ofrest be# neath a stamping` mechanism. e 1n. the pres.

ent machine improvedmeans is also providedlfor positivelyrotating the brush 'lio'ld ing" and feeding disk from a position'of rest into a position of rest. so that after each rotative step thebrush handle will `be accurately positioned and held with relation to the stampingrmechanism.

Fig. 3 is a side elevation illustrating the machine. o l f Before enplainin g' in detail the present limprovement and modev of `operation thereof, I' desire toh'ave it understoodr that 'the inv entionis not limited y.to thedetails of constri'ic'ti'on and arrangement-of partis which are illustrated in.y the'accoinpanying drawings, since theinvention is capable' of other em 'bodiments and'thatthephraseology which and vn'ot'vof limitation.

IV .employ is for the pupose ofE 'description y"a bracket 25 illustrated a' present ypreferrecl form or 'ern'- bodirnent of my invention, it will 'be seen that the machine comprises a suitable support or vpedestal 9` uponv which is mounted a stationary table or 'support 10and rising from the 't'nblev` 10 is a supporting frame 11' having` a` forwardly extending overhanging arm'12. ,Y Carried by the arm 12fis ai-reciproeating ram 13l upon which is supported the stamping mechanism, and the ram vmay be operated in any suitable manner as is Well known in :the art. A shafty 14 isjournalled in suitable bearings in the upright frame. 1'1

and is connected for rotation to a 'suitable source of' power. Carried by the shaft 14 isla sprocket Wheel 15 having driving/connection with 'sprocket wheel 16 secured to a `stud shaft 17. Mounted on the outer end of the shaftl 1T is a mitre gear 18l in'mesh witha gear 19 secured to Lthe upper endlof a ver,- tical rotary -shaft 20. The shaft 20operates in suitable bearingscarriedby the upright frame 11 and secured to the lower end of'this shaft is a horizontalsprocketwheel 21. The sprocket 21 is connected by means of a chain 22l to a sprocket 23'secured to the lower' end o'f ashaft 24 Supported in the outer end of `carried by the .support o1' bedlO. he.

Secured'to 'the uppervend yofthe shaft24 is a rotary disk 26 which operates in :la lc'ircular'opening cut or formedl at one edge of a stationarybedfplate 27. This iplate.` is supported on a post 30'rising from the lbed 10, and mounted upon the'bed plate is a Hat diskor plate 28.` vThe disk 28'forms the brush feeding and holding member of the machine'and rotates on a stud 29 projectingy centrallythelreoffrom'the postBO. A spiral fbedp'late'27X and the force of this spring vmay be adjusted by means of the adjusting nut-32.

Referring particularly to Fig. 2', it will be seenthatthe disk or plate 28 is cut away Vor formed withfa@Series of radial slots 34,

outer -po'rtion 'thereof*beln'gl arcuate 'or' loo curved in form. The rotary disk or driving member 26 is provided With a projecting stud or roller 5 so that upon rotation of the member 26, the stud or roller 5 Will successively travel into'and out of the radial slots 34.

From the foregoing, it Will be seen that the rotary disk 26 and the disk 28 form respectively the driving and driven members of a Geneva. motion, and as a result of the cooperation of these members through the medium of the said rolle-r 5 and the radial slots 34, the brush holding and feeding disk 28, which itself forms a part of the Geneva motion, is rotated upon the bed plate 27 with a step by step movement.

Intermediate each adjacent pair of driving slots 34 of the feed disk 28, the latte-r is provided with straight radial slots or openings 36 which are so constructed and formed as to receive the handle 37 of the article to be stamped such as a tooth brush. Mounted upon the disk 28 are clips or loops 38 at the inner ends of the slots 36 and adapted to assist in retaining the brush handles 37 in position. The bed plate or supporting table 27 is cut away to provide a discharge opening or slot 39 at one side thereof so that at the completion 0f each intermittent movement of the feed disk 28 a` slot 36 Will register with the discharge opening or slot 39 in the table, thereby permitting the brush to be discharged therethrough by gravity into a suitable chute 40.

At the stamping side of the feed disk 28 opposite to the delivery point thereof, a support 41 for the table or bed plate 27 is provided, this support resting against the underside of the table and being carried by the bed 10. This support 41 may be adjusted relatively to the bed plate 27 by suitable mechanism operated through the medium of the handivheel 42. The press or ram-13 reciprocates vertically above the support 4l and is provided with a suitable lettering stamp 43. Each brush handle as it is fed in a step by step movement is stamped with suitable lettering When it reaches the position designated A in Fig. 2,V and thereafter the brushes are carried around by the `feed disk 28 and discharged through the opening 39 in the bed plate 27.

The feed disk 28 is formed intermediate each adjacent pair of radial driving slots 34 with portions 34L having an arcuate .or curved edge 34, this edge being concentric with the axis of rotation of the driving disk or member 26. Thus in operation, it will be seen that the stud or roller 5 while travelling into and out of the slots 34 Will always be guided in engagement With the curved edge 34h. These portions, therefore, act to hold Vthe 'disk 28 against acceleration or momentum, and by means of the spring 33 which forces the feed disk 28 into frictional engagement With the bed plate 27, the rotation of disk 28 is yieldingly resisted. Therefore the arcuate or curved guide portions 341 cooperate With the stud or roller 5 to cause the feed vdisk 28 to be rotated from a position of rest into a position of rest and this is assisted by the action of spring 33.A As aresult of the construction, the disk or holder 28, at each intermittent movement thereof, carries a` brush handle, accurately into position beneath the stamp 43 so that the lettering Will be stamped in the correct placeon the handle or brush. It is important to'note that the revolving feed plate 28 itself forms a part of the Geneva motion and is givena relatively short period of rest when the stamping takes place and a relatively rapid movement between the stamping operations. l
