COUNTING FRAME.

yApplication filed July 26, 1927, Serial No. 208,561, and in Germany J'une 7, 1927.

This invention relates to a counting frame and consistsV in the provision 'of a vertical row of horizontal shafts, andA aplurality of independently rotatable counting members threaded on each shaft, the counting memf bers being adapted to hold detachable count# ing elements in the form of plates, objects.

or the like.

Y Thecounting members are adapted to en-y gage the shaft resiliently and to be retained thereon in diferentangular positions, and detachable grouping members for the counting members are provided. i

Fig. 1 of the accompanying drawing'represents a front view of kthe counting frame,

Fig. 2, anend view of the same, Fig. 3, a perspective View on an enlarged scale of one ofV the counting members according to one construction, Y Fig. 4, an end view of the frame showing the attachment of the grouping member,

Fig. 5, a perspective view onan enlarged scaleof a modilied form of counting member t Fig. 6, a perspective view of yet another form, and

Fig. 7, a side view of the vsame counting member complete with itscounting elements. The counting frame is composed of a vertical row of horizontal shafts such as 1 and 2 secured by screws 4 to supporting frames 3 and'3a. Threaded on each shaft is a plurality of counting members which are independently rotatable, each -shaft being iitted with detachable counting elements such as representations of actual objects chosen from within the range of experience of the child, or plates bearing figures or numbers.

Means f are provided for retaining the counting members on the shafts with one of these objects or plates in view while the others are more or less concealed. For this purpose the shafts are preferably of polygonal cross-section and formed with as many sides as the counting members have numeral plates or objects, the counting members being preferably in the form of'clips adapted to grip the shaft resiliently and to find a resting place on eachside of the shaft. In the illustrated arrangement theshafts have four sides, and the counting members 5 are adapted to carry four plates 6. s

The counting members may be of various constructions. Fig. 3 shows a member com` formed across the center with angular bends corners of the shaft.

posed of two resilient plates 5a which are.

-to t the supporting shaft, the platesibeing interconnected by rivets 8 which are distanced from the bent center portions. so as to allowthe latter to yield and' snap over the of the plates are bent metal stamping, as'shown in Fig. 5. Thev stamping 10 is formed yacrjossthe center with angular bends 14: two of which are set in one direction and one in the other, longitudinal slits being made at op osite sides of the center bend so as to allow t e center portions to yield. Longitudinal slits 11 are also made from the endsof the stamping` so as to forma central arm 12 which is bent in one direction and lateral arms 13 which are bent in the opposite direction. The arms are beaded as previously described.

The. outer portions apartso as to formk dlverging arms 5b between which the platesA -6 are clamped. VFor connection to the plates G, each arm hask at its outer end agbead 9` 65,V

Another alternative construction is shown in Figs. 6 and 7 and consists `oftwo angular plates 15 and 16 one of which is slotted across ythe bend to receive the bent portion of the other plate. The intermeshing plates are applied to the shaft whereon they tained by resilient tongues 17 which are formed on the slotted plate and arranged so as to bear against and support theother plate. In this instance the arms are formed with beads 18 behind which one set of diametrically opposite number plates 6 may be inserted, the other set of number plates being formed with hooked ends adapted to engage over the beads.`

The counting members may be dividedl on the frame into groups for which pur ose grouping members 7 are provided. uch grouping members mayv consist of a bar the ends of which are bent back at an acute Aangle to form supporting arms'7 and 7b.

One of these arms is forked for engagement with the upper shaft 1, the other arm being placed loosely against the shaft 2.

I claim:

1. A.v counting device vcomprising a shaftl are re-V p 2 :lyrisme on, and aplurality of counting elements carried by each counting member.'

2. A counting device comprising a vertical shaft, a plurality of independently rotatable counting members mounted on the shaft, 'each 3. A counting device comprising `a shaft of rectangular cross-section, a plurality oi' independently rotatable counting members mounted on the shaft, each counting member having a resilient hub oi angular crosssection to grip the shait and maintain it in any position in its orbit of rotation thereon,

and a plurality of counting elements carried by each counting member.

41A counting device comp-rising a shaft, a plurality of independently rotatable counting members mounted on the shaft, each counting member having a resilient hub to grip the shaft and hold it iiXed at points in its orbit of rotation thereon, and each member also having a series of arms, and count ing elements detachably engaging said arms.

5. A counting device comprising a sha'lt, a plurality of independently rotatablel counting members mounted on the shaft, each counting member having a resilient hub to grip the shaft and hold it in any one ot a plurality of positions, and each member also having a plurality of arms provided with terminal engaging members, and counting elements detachably engaging said terminal engaging members of the arms.

G. A structure as claimed in claim 1 Wherein the shaft is of polygonal cross-section and the resilient hubs of the counting members are of corresponding form. v

7. A structure as claimed in claim 1 Where in the shaft is of polygonal cross-section and wherein each counting member is provided with a resilient hub to grip the sha'lt and carries as many counting elements as there are sides on the shaft.

8. A counting device comprising superposed vertical shafts, counting members rotatably-mounted on said shafts, and a spacing device for separating the members on the shafts into groups, said spacing device extending between and engaging the shafts.

9. A structure as claimed in claim 1 wherein the counting members are composed Aof plates having beaded edges for engagement with the detachable counting elements.

l0. A structure as claimed in claim il wherein the counting members are composed of plates having beaded edges Afor engagement with the detachable counting elements, the counting members having hooked edges for engagement Vwith the beads.

l1. A. structure as claimed in claim 1 wherein the counting members are composed of plates having beadededges for engagement with the detachable counting elements, the beads being of Sshaped cross-section, the counting elements being composed of plates adapted to engage in said beads from both sides.

In testimony whereof I aiiixpmy signature.
