Specification of Letters Patent.

Patented Dec. 24, 1912.

To all whom it may concern Be it known that I, WILLIAM P. SARGENT, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Label-Pasters, of which the following is a specification.

My invention relates to hand operated label pasters in which labels are cut from a strip and applied by a shearing or knife mechanism operated by a movable contact toe or lever, and the object of the invention is to provide a counter which will record the number of labels applied in the ordinary operation of the pastor and will not record blanks or instructions which are cut from the strip by manually operating the shearing mechanism and are not applied, so that a record is kept of the number of applied labels while the operator is free to cut off blanks or printed instructions without having them recorded.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment selected from other embodiments of it for illustration in the accompanying drawings, in which- Figure 1, is a side view, principally in section, of a paster to which the invention can be applied. Fig. 2, is a perspective view of the same showing the invention in application thereto. Fig. 3, is a top or plan view, and Fig. 4, is a side view.

In the drawings 1 is a casing or housing provided with a handle 2 by means of which it is lifted and projected onto the work.

3, is a pivotal contact foot or too.

4:, is a reel upon which a strip of labels is wound and the strip is led over a pasting roll 5, between feed rolls 6 and under a guide 7.

8, is a thumb wheel which feeds the strip through the intervention of the toothed wheels 9 and 10.

11, is a fixed knife or shearing edge and 12 is a pivotal knife which also operates to apply the pasted labels. 7

13, is a shaft to the projecting end of which the knife 12 is attached and this shaft is turned by a spring 1 1 into position for lifting the knife 12 and depressing the contact toe 3, which it does by means of a projection 15 that collides with an arm 16 on the toe, within the limits of the stop 3, Fig. 3.

In applying a label to an object the strip is fed forward by the thumb wheel 8 and after having had paste applied to it projects as at a. in Fig. 1. The operator then presses the device down onto the contact toe 3 with the result that the arm 16, acting on the projection 15, overcomes the spring 14 and turns the knife 12 down across the knife 11. cutting off the label, while at the same time the knife 12 overthrows by reason of its momentum and thus applies the label to the object. When the operator desires to out 01f a blank, or any part of the strip, without applying it, he holds the paster up with one hand and manually pushes the toe 3 with the other hand; thus causing the knife 12 to cut off a part of the strip which falls clear of the machine into any suitable receptacle.

Having thus described a well known paster, an explanation will now be given of the application of my invention to it.

16 is a counter attached to a bracket or other suitable support applied to the housing and it is provided with a crank-arm 17 by which it is operated when the arm makes full strokes.

18, is a bell-crank pivotally connected with a bracket 19 applied to the housing 1. One arm of the bell-crank is connected by a link 20 to the counter-arm 18 and the other arm of the bell-crank is actuated by the free end of a spring 21, the other end of which is held by a fixed bracket 22. This spring 21 when unrestrained or released descends and if the detent 23 is out of action it turns the bellcrank 18 into position for shifting the link 20 and causing it to turn the arm 17 a full stroke toward the right, in Fig. 2, thus operating the counter once. The detent 23 is normally kept in action by a spring 24 and tends to engage a notch or rojection 25 on the bell-crank, and when this detent engages the notch or projection it prevents the bellcrank from being turned by the spring 21 far enough to cause the link 20 to turn the arm 17 through a full stroke, so that no count is registered. The spring 21 is brought under compression or extended by a pin 25 projecting laterally from the arm 15 and the end of the spring 21 works in a slot 26.

applied or were made by manually operating the toe as in cutting off blanks, because the shaft 13 is rocked and the pin 25 lifts the spring 21 into compression and then releases it, so that the spring gives the bell-crank 18,-

link 20 and arm 17 full strokes. However, the detent 23 is normally in action and tends to prevent the bell-crank from making full strokes when the toe 3 is operated manually to cut off labels or in the ordinary way, but the detent is put out of action whenever the toe 3 is operated to apply labels. The detent 23 is centrally pivoted and provided with an endwise movable plunger 28, so arranged that its working end projects slightly beyond the face of the toe 3 when the latter is at the limit of its inward stroke and then the detent 23 is in action and in engagement with the notch or projection 25. The bellcrank 18, the spring 21 which actuates it and the detent 23 and notch 25" constitute a trigger mechanism which can be set with the spring 21 under compression, and the detent 23 in engagement with the projection 25 and which can be released by disengaging the detent from the projection 25 In applying labels the outward stroke of the toe 3 brings the spring 21 into compression and turns the bell-crank 18 into such position that the detent 23 engages the projection 25 or in other Words, the trigger mechanism is set. Under these circumstances the toe 3 can be moved manually to cut off as much of the strip as is necessary or desirable and no count is made, bek cause the detent holds the bell-crank against the force of the spring 21, even when the pin 25 is turned clear of the spring. When the label is applied by pushing the nose of the device onto an object, the toe 3 is turned up into contact with the bottom of the hous ing and in this position the head of the plunger 28 projects beyond the face of the toe and collides with the object thus releasing the detent and permitting the bell-crank 18 to turn a full stroke and so operate the counter once through the intervention of when the foot or tie is moved away from the housing by the action of the spring 1 1 through the shaft 13 and arm 15, the pin 25 is turned and acts on the underside of the part 21 and turns the latter and the slotted end of the bell-crank 18 upward, stretching the spring 27 and shifting the link 20 and arm 17 toward the left in Fig. 2, into position ready for making a count and into position for the detent 23 to engage the notch 25 and prevent the counting action. When the toe 3 is moved toward the housing the portion 16 acts on the part 15 and turns the shaft 13 and also turns the pin 25 downward and away from the part 21, leaving the lever 18 held by the detent 23. When the plunger 28 moves toward the housing the detent releases the lever 18, which then makes a stroke and causes a count to be registered.

WVhat I claim is 1. In a label paster the combination of a housing, a counter carried by the housing, trigger mechanism carried by the housing and adapted when released to operate the counter, a contact toe normally projecting from the housing and having connections with the trigger mechanism and which sets the latter, and a plunger normally projecting from the housing and independent of the toe and which has connections for releasing the trigger mechanism, substantially as described.
