This invcntlon is conveniently applied to a machine like that of my Patent No. 1,969,106, but it is understood that the device can be applied to any machine for counting articles by slightly changing the feeding or delivery path of one blank of a group, to cause that blank to assume a visually prominent position relatively to the others. I

An "object is to provide a mechanism for slightlydeflecting a selected blank from its normal feeding path, and have this deflection occur at the delivery end of a machine, and be controlled by machine power. This deflection is made to occur once for every twenty-five, or fifty or one I! hundred blanks, and thus a deflected blank functions as an indicator, assisting an attendant in counting the blanks as. they are removed, for example in lots of twenty-five, fifty or one hundred.

A further object is to provide a simple counting mechanism which shall act on the surface of the selected blank at two different points to cause the aforesaid deflection.

Features include all details of construction along with the broader ideas of means inherent in the disclosure.

Referring'to the drawings, numeral 2 is the frame of the machine to which my invention is applied, and 3 is a carrier belt operatively re- 10 lated to a pulley 4 journaled in the frame. At 5 is showna pressure drum, under which the blank 6, resting on the belt 3, passes. At 1 is an idler pulley urged against the belt 3 by a spring 8. Support'for the idler pulley I and the 15 spring 8 is a holder 9 mounted to be adjustable crosswise of the machine as by a suitable guide It).

In practice, the idler pulley I. is adjusted to bear on the left-hand side of the upper surface of the blank, as shown in Figures 2 and 4, thus 0 acting while the blank passes from the pressure drum 5 to the stack, and additionally acting as a kind of pivot about which a selected blank is swung to be projected laterally of the line of feed.

The main feature of my invention will now be described. At II is a driven roller set ahead of the roller 4 and having a surface speed greater than the surface speed of the belt 3. Numeral l2 designates a wheel which cooperates with roller H to deflect a blank, and said wheel is shown out of contact with the blank 6 in Figures 1 and.

2. With the wheel l2 raised, the blanks are delivered in a straight line onto a suitable slow moving conveyor belt l3, having the usual stop roller l4 and a guide or deflector plate l5. The blanks are thus stacked or overlapped and in this case, the deflector mechanism acts just before the blank is delivered to the stack. This feature is also claimed, along with the broader idea of 40 means of moving a selected blank laterally to facilitate counting.

In order to deflect a selected blank from. its normal path, as in Figure 4, the blank deflector wheel is forced against the sheet by a spring, thus forcing the sheet against roller ll. Since the roller' H travels at a greater speed than the speed of the belt 3, and sincethe element is pressing the blank, the blank is moved sideways. The blank pivots about the contact point of roller'l.

for causing oscillatory motion of a link member connection at 20 having a rod 2| pivoted as .at-

22 to an arm 23 adapted to rock a shaft 24, for every revolution of an eccentric 26, mounted on a shaft'26, and connected by strap l6 with link I 1. Referring to Figure 9, the arm 23 is seen to be offset and is pinned or otherwise secured to the shaft 24. This shaft has bearings at 28 and 29 in a casting 30. Referring to Figures 9, 10 and 11, an arm 3i is pinned or otherwise secured to the shaft 24 and has a pawl 32 held in contact with a ratchet 33 by a spring 34 (see Figure 10), the ratchet being rotatable on shaft 24. As the arm 3i moves the pawl 32, the latter advances the ratchet step by step. To prevent reverse motion of the ratchet, a suitable idler stop pawl 35 is provided (see Figure 11). Mounted on a hub 36 of the ratchet 33 is a disc 31 secured to the hub 36 by a set screw 38, for purposes of adjustment. This disc 31 has notches 39, preferably two, in its periphery, and preferably diametrically related.

The casting 30 has a depending arm 40 (see Figure 9) and carries a bearing 4| for supporting a shaft 42 (see Figures 2, 6 and 7). This shaft has a collar 43 at one end of the bearing and an arm 44 at the opposite end. The arm 44 is provided with an adjustable threaded pin 45 adapted to bear against the periphery of the disc 31. As the disc 3'! revolves step by step, the pin 45 eventually drops into one of the notches 39 (see Figure 5) permitting shaft 42 to turn under the action of a spring 46 secured to a pin 41 which is screwed to the collar 43. The spring 46 serves to keep the pin 45 in contact with the periphery of the disc 31. This turning of the shaft causes the deflector. wheel i2 on arm 48 to engage the blank 6 and so increase its friction against the faster moving roiler Ii, as to cause that side of the blank to move at a greater rate of speed than the opposite side, thus deflecting the blank, as shown in Figure 4. The pressing action of wheel I2 is only momentary, continuing until the pawl 32 again moves the ratchet wheel 33. Contact of the deflector wheel l2 with a blank is so timed that deflection of a blank occurs only after twenty-five, fifty or one hundred blanks have passed the wheel i2. The roller H may be driven in any desired manner. The particular means here shown (see Figures 12 and 13) is through a spurgear 49 on a shaft 50, meshing with an idler 5i which in turn is secured to a spur gear 52 which meshes with a gear 53 mounted on shaft 54, to which the roller ii is secured. Pulley 4 is secured to the shaft by a set screw 55. The shaft 54 is mounted in suitable bearings 56, 57, and the shaft 50 is mounted in suitable bearings 58 and 59.

There is no intention to be limited entirely to the details of construction although these are also claimed. Features of the invention include broadly the idea of providing means which acts intermittently and when actingacts momentarily to feed one side of the blank at greater speed than the other side and thus obtain deflection; and the use of means acting as a pivotal point about which the blank swings when the first mentioned means momentarily acts.

in my I also claim the method by which two feeding means are caused to act simultaneously on an article while being fed one laterally of the other.

I claim as my invention:

1. An article counter including, two article feeding means respectively operating at different speeds and acting on the same face of an article, and means intermittently acting on the opposite face of the article and controlled by one of the feeding means for causing that feeding means which operates at the greater speed to act momentarily to deflect a blank from the-normal line of feed, both feeding means having widths not less than that of the articles being fed and constantly acting on the entire transverse width of the blank.

2. An endless feeding conveyor, and a feeding roll arranged forwardly of the forward end of said conveyor, a second conveyor to which the articles are delivered after passing over said roll, means by which the roll is operated at greater speed than the feeding conveyor, a second roll above the feeding plane and over said feed roll, and means for periodically and momentarily causing the second roll to engage a selected article and press it into firmer contact with said feed roll, and means acting simultaneously to apply pressure to the article at a point laterally of the contact point of said second roll with said article.

3. An article counter comprising two feeding surfaces operating on one face of an article at different surface speeds, the one operating at the greater speed being in advance of the other, and adapted to receive and advance the article independently of the other, a roller acting on the opposite side of the article to press the article against that feeding surface which travels at the lesser speed, and a second roller having substantially only a point contact at the same side of the article to press the same against the feeding surface which has the greater speed.

4. An article counter including two surfaces moving at difierent speeds, and both of which simultaneously act on one face of an article to feed it, means momentarily acting on the opposite face of a selected article to press it against that feeding surface which operates at the greater speed, said pressure means acting at a point intermediately of the opposite lateral confines oi said feeding surfaces.

5. An article counter, including two surfaces moving at different speeds, and both of which simultaneously act on one face of an article to feed it, and means momentarily acting on the opposite face of a selected article to press it against that feeding surface which operates at the greater speed, means for supporting said pressure means whereby it may be adjusted transversely of said feeding surface to apply pressure at any point transversely of said feeding surface.

6. An article counter including two surfaces moving at different speeds, and both ofwhich simultaneously act on one face of an article to feed it, said surfaces operating on parallel axes which are at right angles to the line of feed, and pressure means selectively acting momentarily on the opposite face of said selected article to press it against the feeding surface which operates at the greater speed.
