Application filed. August ;1926; ;Seria1 Nd. 130,418.;

This invention relates to a moistening device, particularly adapted for use in connection with a mail sealing andstamp canceling machine. In a sealing apparatusfor this pur pose, means must be provided for moistening theflap of theenvelope, so that the ad hesive substance thereon will be'moistenedsufiiciently, so that the envelope-may be quickly sealed, asit passes over the sealing rollers. A V

. It is the object of my invention toprovide a moistening device which will perform the functions of carrying a moistening liquid,

such as water, to the-envelope, in a highly eflicientinanner. Another object of my invention is to provide a moistening apparatus which will give long life and service, and one in which the parts may beoui'ckly ,ad-. justed for suitable operation. f

- :These andvother objects will be apparent to one skilled in this art, after areading of j the .specification taken in connection with the annexed drawlng, wherein-e Figure 1, 1s a'partial side view on a much reduced scale of a, machine to, which my improvement is adapted,-

'ssIGNoR To iitirnanaaionan A support member 18 having preferably integral therewith a bearing hub 17, is attached to the frame 1, that is tosay, the v outside portion of the bearing 17 fits in the frame '1; 'Carried by the bearing 17 f isa'shaft'16, connected'with any satisfac tory driving means used in machines of this character.- On" the outer end of the shaft 16 sthe pulley wheel 4, already; referred to.

5 On the support member-18, 'there is carried two studs 25 and 32, preferably one of nut 27 On the stud 32ispivotally supportthese studs isadjustablelongitudinally of thesupport, as by means of aslot 26, and a 7 ed :a drivingjmember or sprocket 28, while on thestud 25' i's-rotatablyjsupported a similar dr1ving member; or sprocket 24, and carried by the sprockets 24 and 28 is a chain 19;

The 'cl 1a-i1'119,is made up of alternate links v comprising side 'bars20 and 21, between the extremitie's'ofwhichare positioned connecting bars 22; The'bars'2O and 21, carry an eyelet bushing 23, so that the connecting bar 22, is pivoted on this eyel'et'as isomore clearly shown'in Figure 4. Each eyelet carries "a brush 36, preferably made of hair or bristles or [other satisfactory material, which are formed in thev shape of hairpin loops, ,a.nd passing around these loops, preferably a number of times-is a binding member 33, 3

preferably of fcjopper wire, which can be; readily solderedas at 34 tojthe end of the eyelet and to thebar21. 7 Asshown in Fig} ure 4, a space 34 isjpurp'osely indicated so as to showthe'binding wire 33in position.

Sinceflthebearingstud-25 is adjustable with respect to the"stud"32, the proper tension on the feed chain may be obtained. The

support-18,together with the bearing bush ing-17. maybe adjusted longitudinallyof the shaft 16," so as to 'givethe proper pressure onthe ends of the brushes 36, as they pass by the inner flap of theenvelope, this ad thebrushesas they wearwith use. g As Will be s en in-Figiif3; the stud 32 lowerextremity'ofthe chain '19 dips "into the 1 i iustment alsoprovides 'f or 'properi'setting of 0 receptacle 12 a suitable distance and the brushes 36 pick up the moistening fluid, such as water, and carries it to the flap of themvelope.- While I have shown the chain 19,

in a vertical position in igures2 and 3, it is to beunderstoodthat'in practice the support 18, together with the chain 19,;may take an angular position, to secure proper working relation of. the parts. i I

teeth 38 are adapted to pass over the rounded ends of theconnecting' links22, so that the driving is all applied t'oEthe connecting links 22, and not directly on the bearingeyelets 2 3 or other parts,

'lVhile I; haveshowna preferredform of applying invention it is to be understood that the details may be varied without departing; from the spirit or scope of the ap- V pended claims.
