My present invention relates to means for moistening strip material, or for delivering strip material in moistened or adhesive condition, such material including adhesive or gummed tape and labels, particularly for use in connection with packaging, labeling and the like. It aims to provide an eflicient, simpliiied and otherwise improved means of the class referred to. This application is a division of my copending application S. N. 451,773, led May l2, 1930, now patent No. 1,959,293, dated May 15, 1934, and also of my copending application S. N. 603,777, filed. April 7, 1932 as a continuation in part of said first mentioned application.

,In the drawing, illustrating by way of example certain embodiments of the invention,

Fig. 1 is a longitudinal vertical section through the fore portion of a strip-serving machine or apparatus and illustrating one form of strip delivering, and moistening or adhesive-rendering means, in accordance with my invention;

Fig. 2A is a corresponding view of a' modied form of the moistener-cooperative strip-guiding means of Fig. l;

Y Fig. 3 illustrates the positioning and adjusting means of Fig. 2, looking at said ligure from the left; and

g Fig, 4 is an enlarged section ori the line 4-4 of Fig. 3.

Referring first more particularly to Fig. 1, the

means there illustrated comprises a frame or housing, including a base I and side walls, one of which is seen at 2. The side frames may be suitably interconnected, as by means of the cross strap seen in section at 4. The housing may be formed of one or more sections of sheet metal, or .otherwise constructed, and desirably rests on cushioned feet, one of which is indicated at 5. In Fig. 1 I have illustrated suicient of the forward or delivery end of the apparatus to aff ord a complete understanding of the invention. VThe strip-moistening or adhesive-rendering means comprises a reservoir 6 adapted for removable reception on the base I and between the frame sides 2, wherein it may be longitudinally positioned as by a rear stop 1. The reservoir herein includes a rear top wall 6a.

, In conjunction with the reservoir I have herein provided novel means for supporting a capillary-feed or brush moistener 8 in improved cooperative relation with the strip to be moistened. It will'be understood that in the case of previously gummed strips the reservoir is supplied with water for conduction to' the strip by the brush moistener, or if used with non-gummed material the reservoir is supplied with suitable adhesive, such as mucilage or the like. In the present embodiment of the invention the moistureconveying fibers or hairs of the brush 8 are held against objectionable flexing either at their free 5 ends or elsewhere. For this purpose, the front Wall 9 of the reservoir is extended inwardly and downwardly as indicated at 9a, at an angle approaching the horizontal, approximately 45 degrees as shown. 10

In substantial continuation of the inclined portion 9a is a flat brush rest I0 in which the moistener or brush is removably but firmly positioned as by the reversely extending clamp or holder Illa. This brush support as a whole is vertically yieldable, and for this purpose the rest or support I0 is in this instance pivoted on the reservoir in any suitable manner, as by means of the pivotal connection illustrated at II, and the rest is urged upwardly as by the spring means I2. The reservoir and brush are removable from the apparatus as a unit, a finger piece I3 being herein provided to facilitate their insertion and removal. .Y

The strip or tape T coming from a suitable supply, generally in roll form, is passed across the brush in a path herein approaching parallelism with its hairs or bristles. In cooperative relation With the brush, I provide an overlying plate or guide I4, which may be variously constructed and arranged. In the form of Fig. 1, such plate or guide comprises the cross-member I4, seen in section, between the side frames 2 and having lateral flanges I6 by which it is secured to the latter, as by means of the .bolts or screws I6a. The rear edge of the guide or plate I4 preferably is upturned as at I'I for reception of the leading end of the strip or tape T and to assist in guiding it to and across the moistener, the latter being urged upwardly by the spring means I2 into efficient moistening relation with the under face of the tape as it Vpasses between the brush moistener 8 and the guide or plate I4. f

The strip guide or feeding means andthe means for cutting olf a length of the strip are suiliciently illustrated in Fig. 1 to afford an understanding of their cooperative relation to the described moistening means, and of the operation of the apparatus as a whole, it being understood 5() that the moistening device or unit is susceptible of use separately, as for moistening labels and the like, and in combination with strip-serving apparatus of various constructions. In the apparatus illustrated by way of example, there is in- A post 52 hung from the cover 30.

cluded a vertically movable cover spanning and supported on the side frames, its front portion being seen at 30. 'Ihe cover carries a strip guide throat including the spaced upper and lower Walls and 36 which provide between them a forwardly and downwardly directed channel for conducting the tape to the severing and the moistening means. These channel or throat members 35, 36 terminate substantially at the point at which the strip is to be cut 01T, from which point the strip is accurately guided for delivery to and past the moistener, herein by the fore portion of the cross-strap 4 previously mentioned, serving as a table or platform, in cooperation with the upturned rear edge I'I of the guide plate I4 and with a preferably somewhat resilient piece 39 secured to the cross-strap 4 and formed to extend across from the front edge of reservoir top wall 6a into substantial engagement with the brush 8 ad jacent the line of engagement of the strip 'I with the latter. 'I'he front portion of said piece 39 desirablyV is in substantial parallelism with the brush and. assists in properly directing its hairs or bristles.

While any preferred means may be employed for cutting off the strip I have illustrated for that purpose mechanism as more fully shown and described in my copending applications mentioned. This severing or cutting mechanism comprises a movable knife or blade 49, the lower cutting edge of which may be tapered or otherwise inclined transversely as in said previous applications. This knife is carried on a vertically movable knife lever, the front end of which is seen at 43. The knife and its lever are normally urged upwardly by suitable spring means, not shown, and which, as in the copending applications, may bear between the lever and a shelf, the front end of which is seenat 50, supported on a stud 5I on a The knife 4U may be depressed to sever the tape by manually engaging its flanged portion 45a, or a knife actuator or operating plate 53 may be provided. As shown, this knife-operating-plate is formed with eyes 54 by which it is pivoted on a bar 55 on the cover 30, the actuator bridging the space between the upper level of the tape guide channel 35, 36, and the severing blade 40. By means of the actuator 53.the blade is adapted to be operated during a substantially straightline continuation of the movement of the operators hand in the direction of the tape feed. 'I'hat is, the operators fingers move uninterruptedly from the bar 53, which acts as a stop or limiting means for v the tape feed, across the plateor actuator 53 and thereby depress the knife 4) and sever the tape or strip against the cross-member 4, the latter being slotted as at 4a for the passage of the blade.

One modified construction for the strip guiding plate which cooperates with the brush moistener is illustrated in Fig. 2, wherein like reference numerals refer to like parts as in Fig. 1 and partsinot otherwise referred to may be understood to be the same as in said gure. Referring to Fig. 2, I have therein provided a guide element or strip depressor I4a. This guide element is disposedV in opposing cooperative relation to the brush moistener 8 and, as in Fig. 1, is normally stationary` but is variably positionable. It is pivotally'supported as by the stationary pin I8 extending transversely of the side frames 2, and has attached to it an upright post I9 projecting loosely through spaced ears I9a on a lug I9b which pivoted in the adjacent side wall 2. A

nut I 9c is adjustably threaded on the post I 9, between the ears I9a; thus by turning the nut, the guide element or plate I4a may be raised or lowered and held in the desired adjusted position with respect to the brush, the ears and their lug I 9b swiveling in the side frame to permit the desired positive adjustment. During operation of the moistening means the plate thus remains xed in its desired adjusted position, the brush being urged upwardly against the plate, or against the under face of the strip when the latter is present below the plate, by its spring means I2.

It will be understood that the invention is not limited to the particular illustrative embodiments thereof as shown and described, its scope being pointed out in the following claims.

I claim:

1. In a strip serving device, a liquid reservoir, an inverted brush therein, a brush carrier including a member inclined in the direction of strip feed and supporting the hairs or bristles through the major portion of their length, said carrier having its lower portion hingedly connected to the reservoir, and spring means urging the carrier upwardly about its hinge.
