2 Claims. (01. 235-98) This invention relates to counting devices and to provide an opening l6 through which articles is illustrated herein as embodied in a device parto be counted are dropped. The cover portion l4 ticularly adapted for counting wood heels. is provided with an opening l8" below which is In counting articles such as heels to be placed m un d a otary c u 20 0f e yp disclosed in shipping containers it is important that such in United States Letters Patent No. 1,47 5 articles be accurately counted. This is imporgranted October 16, 1923, on an application filed tant in the manufacture of wood heels where the in the name of Henry A. Chase.

In order The frame is illustrated as composed of wood to prevent such false counting, the counter 20 but it is evident that it may be made of any other is loosely and yieldably mounted upon the supsuitable material. The frame I0 is provided with Aport 22. Referring now to Fig. 3, it will be cover portions [2 and I4 spaced from each other noted that the support 22 is cut away in its 5 upper surface to receive a pad 36 of some relatively soft, yielding material, such as leather. The counter 20 is provided with a flanged base I! having four screw receiving holes therein. The base of the counter 20 is placed on the pad 36 and screws 4|] are driven through the holes in the base I! and through the pad 36 into the cross piece or support 22. The screws 40 are not driven tightly against the upper surface of the base 38 but are driven with the heads of the screws 40 just out of contact with the top surface of the base 88. In other words, the counter 20 is free to move slightly relatively to the support 22. By the use of such a mounting undesired operation of the counter is prevented and accurate counting is insured. The mass of the counter 20 is substantially greater than the mass of the arm 28, the cross piece 30 and the fingers 32. When the fork, comprising the arm 28, the cross piece 30 and the fingers 32, swings back to its original position, the arm 28 strikes the stop 2| on the counter 20. The momentum of the fork causes the counter 20 to be slightly moved. Since the mass of the counter 20 is substantially greater than the mass of the fork, the velocity of the counter 2|! and the fork moving together is proportionately less than the velocity of the fork before it strikes the stop 2|. The fork and the counter 20 move together a small distance until substantially all of the momentum of the fork has been absorbed but at the end of this movement the parts are in an unbalanced condition and the parts then move together in the opposite direction. During this movement, the velocity of the parts is small and the momentum proportionately small. The spring 24 is sumciently strong during this latter movement to hold the arm 28 against the stop 2| so that there is substantially no relative movement between the fork and the counter 20. At the end of the'retum movement the parts swing below the normal position of the fork but the parts return to normal position partly because of the yielding pad 2| and also because there is some slight rebound of the parts when the lowest point of the return movement is reached. The counting mechanism, therefore, can not be operated by the oscillation of the fork.

Although the parts of the device have been described in detail the operation of the device will now be briefly summarized. For example, if heels 42 are to be counted the operator may place a single heel or a pair of heels upon the fingers 32. The weight of the heel or heels will depress the fingers into the position shown in Fig. 2 until they engage a stop ll secured to the under side of the frame ll. When the fingers 32 are in this position the heels 42 will slide off into a box or other container. The fingers 32 will then be returned to horizontal position by the spring 2|. As previously stated, the arm 28 strikes the stop 2| on the counter 20 and the fork and counter 20 move together upwardly until the momentum of the parts is absorbed or dissipated. At the end of this movement the parts move in the opposite direction and finally come to rest. There is, therefore, substantially no relative movement between the parts after the fingers have been returned to horizontal position and false counting is thereby prevented. The parts of the device are now in position to count another article or articles.

Although the illustrated device has been described, particularly in connection with counting heels, it is to be understood that the invention is not limited to counting such articles but may be utilized for counting other kinds of articles, if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A counting device having, in combination, an open bottomed supporting frame, a counter yieldably mounted on said frame, said counter being provided with counting disks mounted for rotation in said counter and a shaft arranged to be rotated to operate the counting disks, an arm secured to said shaft, a plurality of relatively resilient fingers connected to said arm, said arm and said fingers being normally disl0 posed in a substantially horizontal position and arranged to be depressed by the weight of the article to be counted a distance sufficlent to rotate said shaft to operate the counting disks and to permit the article to slide 011 of said fingers and into a receptacle, and a spring operatively connected to the shaft to return said arms and said fingers into substantially horizontal position.

2. A counting device having, in combination, an open bottomed supporting frame, a counter loosely secured to said frame, said counter being provided with counting disks mounted for rotation in said counter and a shaft arranged to be rotated to operate the counting disks, a yield- 45 able pad interposed between said frame and said counter, an arm secured to said shaft, a cross bar secured to said arm, a plurality of resilient fingers secured to said cross bar, said arm and said fingers being normally disposed in a substantially horizontal position to receive articles to be counted and arranged to be depressed by the weight of the articles a distance sufficient to rotate said shaft to operate the counting disks and to permit the articles to slide off of said fingers and into a receptacle, and a spring secured to said counter and to said shaft to return said arm and said fingers into substantially horizontal position.
