COUNTER-OPERATING MECHANISM FOR STAMP AFFIXERS.

Applicati'on'filed November 1, 1916.

T 0 all whom it may concern:

Be it known that I, WESLEY J. BALKWILL, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Counter- Operating Mechanisms for Stamp Aflixers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this specification, and to the reference characters marked thereon.

My invention relates to a counter operating mechanism for stamp alfixers and has for its object to provide an arrangement of counter or register actuating mechanism whereby an accurate count of the number of stamps or labels discharged from .a machine may be obtained. A further object of the invention is to provide a counter operating mechanism arranged to be positively operated by a portion of='the feeding or other movable mechanism of a stamp affixer or dispenser whereby an accurate record may be obtained from time to time of the number of stamps fed from the machine. To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Figure 1 is an enlarged sectional elevation through a machine embodying the inven- A through the tion;

Figure 2 is a rear elevation of the stamp container and guide mechanism;

Figure 3 is a horizontal sectional view taken on line 33 of Figure 1;

Figure 4 is a fragmentary vertical sec tional view showing the position of the counter operating mechanism after the same has been actuated by Y the stamp feeding fingers, and

Figure 5 is a detail sectional view through the backing of the stamp guideway showing the relative position of the feeding fingers with respect to the counter actuating bar before the machine is operated.

Similar reference characters throughout the several views indicate the same parts.

In stamp or label affixing or dispensing machines where the stamps or labels are fed from a continuous strip mounted in the ma- Specifieation of Letters Patent.

chine in the form of aroll it is essential that an accurate record be kept of the number of stamps and labels fed from the machine, particularly in the case of postage stamps because of their monetary value. The mechmechanism arranged to be positively oper ated preferably by some movable part of the machine such as the stamp feeding fingers thereof which are so positioned as not to come in contact or operative relation with the counter actuating mechanism until the stamp or label to be registered or counted has actually been advanced a distance substantially its full length'by the feeding mechanism.

In illustrating the features of the present invention I have shown them applied to a stamp affixing machine, but it will be understood that the mechanism is applicable to other types of stamp or label feeding machines upon which no afiixing mechanism is used. The machine shown in the drawings comprisesv a base 10 supporting a frame 11 upon which is guided a vertically mounted reciprocating shaft or plunger 12 carrying an aifixing head 13. At one side of the ma chine the frame 11 is open and removably fitted in said opening is a circular stamp or label case 14 containing a roll of stamps or labels 15 shown passing downwardly guideway consisting of the backing 16 and the removable clamping and guiding member 17 terminating in the

laterportions

18 and 19 respectively, which are adapted to direct the free end of the stamp strip over the cutting edge 20 and into the path of the affixing head 13. The stamp or label strip is fed downwardly and suitable feeding mechanism mounted on the shaft or plunger 12 and in the present instance, comprises a plurality of adjacently mounted feeding fingers 21, the pointed ends of which are 'adapted to engage the'perforations between may be conveniently read from time to time.

supporting

pins

29 and 30 are passed, the

' upon the pin 30.

' substantially equal in feeding opposite ends of which are seated in the side walls 31 of the stamp casing. An elongated horizontally positioned aperture 32 is formed through the backing 16 at a point spaced from the point at which the lower ends of the feeding fingers normally rest, to the distance the fingers are made to travel on their downward stroke the stamps successively from the machine. Extending into the aperture 32 is an actuating member 33 for operating mechanism preferably in the form of a rocker bar provided with forwardly extending

arms

34 and 35 pivotally mounted The arm 35 is extended upwardly and outwardly at 361 and is inclined with respect to the backing 16. Pivotally mounted upon the extension of the arm at 37 is a forwardly extending pawl 38, the catch 39 of which is adapted to engage the teeth 40 of a ratchet wheel 41 for actuating or rotating the same step by step to drive the central shaft 42 which is connected with the ratchet wheel.

Theconstruction of the counter mecha-' nism has been omitted, but it will be under- 30 is a pawl 43 which is provided with a stood that the numeral wheels and devices for operating them are driven by the central shaft. ivotally mounted upon the pin shoulder 44 arranged to engage the teeth of the ratchet wheel beneath the ratchet bar for the purpose of preventing rotation of the shaft 42 in a direction opposite to that in which it is rotated when actuated by the ratchet bar. The

pawls

38 and 43 are held in their respective positions upon the ratchet wheel by means of a coil spring 47, the opposite endsof which are connected with the pawls at points intermediate said wheel and arm'36. The pawl 43 isfree to move only upon its pivot, while the'pawl 38 is both pivotally and bodily movable with respect to the ratchet wheel. Consequently by inclining the spring47 rearwardly above the pawl the same will act to normally hold. the pawl 38 in the position shown in Figure 1 which causes the bottom edge of the operating bar 33 to project through the aperture 32 farther than the top edge, or in other words, serves to normally holdthe bar inclined relatively to the guideway or backing 16. The rear face of the bar is provided with a groove 45 into which the pointed ends of the feeding fingers 21 are adapted to pass upon the downward stroke of said fingers as the counter said means serving the bar 33 is moved by} the fingers 21 from the position shown in Figure 1 to that shown in Figure 4, the extension of the arm 36 will be moved to a vertical position, thus bodily moving the pawl 38 to cause the rotation of the ratchet wheel and counter operat ing shaft 42 a predetermined amount suflicient to cause the proper registration of the forwardly fed stamp. As soon as the plunger 12 is released the feeding fingers are re turned to their normal position, previous to which time the spring 44 carries the catch 39 of the pawLover into engagement with the next succeeding or forwardly positioned tooth upon the ratchet wheel thereby actuating the arm 36 to reset the bar 33 as shown in Figure 1. The bar'is preferably grooved on its rear face as shown to positively insure its operation by the pointed ends of the feeding fingers as they are moved downwardly.

This is accomplished by inclining the lower strip is fed.

It will be observed that the feeding fin-' gers 21 are inclined in the direction of their movement toward the stamp guideway and yieldingly engage with the stamp strip therein, so that during the feeding movement they exert a tendency to push toward the back wall of the guideway. Consequently, the stamp strip, as it reaches the aperture 32, is deflected slightly, thus permitting the operating device for the counter to be actuated. movement of the counter is displaced laterally out of its normal position by the pressure applied through the stamp strip and this displacement, in the parts as shown, is a rocking action of the which extends transversely in rear of the stamp strip and is pivoted in proximity to the rear wall of the guideway.
