5 Claims.
The present invention relates to separators and. feed rollers for mail canceling machines. More particularly the invention pertains to the adjustment of the separator roll, these means automatically positioning the separator roll when the diameter of the latter diminishes due to wear and insuring proper separation of the mail matter as it is fed to the printing device constituting the means for marking the mail and canceling the postage thereon.
Heretofore adjustment of the separator has been accomplished by manually operated means, such, for instance, as a screw, and the proper positioning thereof with respect to one of the feed rollers was left to the judgment of the operator. While the wear on the separator and feed rollers, usually faced with rubber, is relatively small, nevertheless, in spite of the infrequent necessity for adjustment, the separator roller did not always function properly. It has been found from experience that the average piece of mail matter could be separated from a stack by setting the distance between the separator and feed roller at a predetermined distance. It is obvious that, to maintain this spacing, considerable skill would be required on the part of the operator properly to adjust the separator and maintain a fixed relation between the separator and the feed roller.
It is an object of the present invention to provide means for maintaining a predetermined spacing of the separator and feed rollers in the type of machine to which reference has been made, and, with this object in view, a preferred mechanism for efliciently separating mail matter has been devised. The following description of this mechanism will enable those skilled in the art readily to understand the automatic adjustment, particularly with reference to the accompanying drawing, in which:-
Fig. 1 is a top plan view of the separating mechanism;
Fig. 2 is an enlarged view, partly broken away, of the separator roll and spacing means;
Fig. 3 is a front view, partly in section, of the separator shown in Fig. 3; and
Fig. 4 is a section taken on line 4-4 of Fig. 3.
Referring to the drawing, there is shown a separating mechanism comprising the usual feed rollers l6, II arranged in juxtaposed relation and rotating in the direction indicated by the arrows thereon. These rollers are positively driven and geared to each other in such a manner that the angular velocity of roller I0 is greater than that of roller II.
Each of these rollers is provided witha facing I2 in the form of an annular rubber ring fitting snugly on the roller and adapted to frictionally engage the mail matter passing through the canceling machine. Disposed forwardly of roller II] is a separator roller I3 driven in a direction opposite that of roller I0. Roller I3 is likewise provided with a rubber facing I4.
As will be seen in Fig. 2, the periphery of the facing on roller I3 projects slightly beyond the face of a bifurcated guard member I5 forming part of the separator plate, the latter being fixedto the frame of the machine. The function of the rubber faced roller I3 and the guard I5 is to prevent more than one piece of mail matter from entering the feed. This will be evident from Fig. 1 in which is shown a stack of mail, indicated at I6, and forced against an inclined feeding finger I! and stop plate I8 so as to project the edges of successive pieces beyond the edge of the next piece of mail. Usually a feed belt (not shown) forces the mail against the finger I'I, stop plate I8, and guard I5.
As shown in the several views, roller I3 is pinned to a shaft I9 journaled in a depending projection 2|] on arm 2|, the latter being pivotally connected to, guard I5 at 22. This arm and the roller I3 carried thereby are normally urged toward roller I0 by spring 23 secured at one end to guard member I5 by means of screw or pin 24 and at its other end to the depending portion 25 of an arm 26 adjustably secured to arm 2! by a screw 21. Journaled in bosses 28 on guard member I4 is a shaft or pin 29 which rotatably supports a positioning sleeve or roller 30 between the furcations of the guard member.
As will be evident from the drawing, sleeve 30 acts as a limiting stop for roller I3, its position being such that the periphery of the frictional facing I 4 projects beyond the guard a distance indicated by X in Fig. 2. This distance remains constant, regardless of wear on the rubber facing, because, as the diameter of the roller diminishes, the spring 23 urges the roller against the sleeve at all times and maintains relation between the projecting periphery and the guard substantially constant. Thus, it is apparent that, once the roller. and sleeve have been so positioned to permit roller I3 to project the proper distance beyond the face of the guard, the roller is automatically urged against stop sleeve 30 when the facing I4 wears. Hence, no manual adjustment is necessary.
As stated hereinbefore, separator roller I3 is reversely driven with respect to feed roller II).
In operation, the separator prevents the passage of more than one piece of mail at a time. The stack of mail, resting on the lower edges of. the pieces, is urged toward the guard and'the edge of the piece nearest the feed rolls projects beyond the edge of the next succeeding piece. The piece of mail nearest the feed rolls is frictionally engaged by rolls H), II, the former of which rotates relatively rapidly and carries the piece past the separator. Until this piece'has passed beyond the feed rolls, the next piece is urged away from the feed rolls by the separator until such time as it is presented to the friction faces of the feed rolls, that is, when the preceding piece has passed the rolls. By providing a stop device and means always urging the separator roll against this stop, the projecting portion of the separator facing remains constant at all times.
While'a' preferred form of the invention has been illustrated and described, it is not intended that the invention be limited to the precise arrangement of parts shown, but may be modified within the, definition of the invention as expressed in the appended claims.
