Patented June 21, 1938 UNITED PATENT OFFICE 9 Claims.

This invention relates to non-repeating indicaters adapted `for use in connection with games, sales promotion contests, and the like.

The primary object of the invention is to provide a device which cannot be tampered with or controlled by the user and will provide an equal chance for any of the individual characters appearing in the window of the device after each operation.

A further object of the invention is to provide a machine which is of inexpensive but durable construction and has its working parts, for the most part, exposed to the users View.

The invention is illustrated in a preferred em- 1 bodiment in the accompanying drawings, in

whichm Fig. l is a front elevational View of a machine embodying the' invention; Fig. 2 an end elevational view of the same; Fig. 3 a broken longi- `tudinal view of the machine partly in section; Fig. 4 a sectional View taken as indicated at line 4 of Fig. 3; Fig. 5 a broken sectional View taken as indicated at line 5 of Fig. 3; Fig. 6 a fragmentary View showing a crank, in section, with its associated driving arm; Fig. 'I a fragmentary view showing a portion of the starting mechanism and cam release; and Fig. 8 an enlarged broken sectional View of the cam release taken as indicated by the line S of Fig.' 7.

In the embodiment illustrated, A designates a. housing frame in which is journalled a supporting shaft A'; B, rotatable members independently journalled on the shaft A; and C, weighted membersfor automatically aligning characters carried by the members B with a desired portion of the housing frame A.,

The housing frame may be of any suitable construction, and is shown with a sheet metal base 9, provided with legs lil and upwardly extending standards ii and l2, in which is joui-nailed the shaft A. Ornamental sheet metal discs it and il. serve as end closures for a transparent cyllnder Hi, which may be made of glass, celluloid, or the like. The transparent cylinder, preferably, is provided with a suitably designated window I6, in which the characters, carried by the rotatable members, will appear when the rotation is stopped. The ends i3 and il! may bel held together by suitable tie rods il, equipped attheir end portions with threaded caps i3.

` The rotatable members Bare freely journalled on the shaft A and preferably comprise light hollow sheet metal cylinders formed by securing cup-shaped members i9 together in spaced .relation by means o capped studs 2i) having a free end 2i projecting outwardly. The cupshaped members l9 may be held in proper spaced relation by means of tubular spacing members 22, which may be slipped over the studs 2B before the members are secured together. The extensions 2| co-operate with the starting mechanism, as will be described below. The members i9, preferably, are provided with a circumferential band 23, on which may be painted or attached suitable characters such as numbers, playing cards, pictures, or the like.

In order that the membersV B will stop with their characters in proper alignment with the Window iii, after being rotated freely, a Weighted member C is provided in each member B. The members may comprise a heavy disc portion 2d, which is encircled by a rubber tire 25 having a diameter somewhat larger than the distance between the equally spaced spacing members 22. In operation, when the members B are rotated rapidly, the weighted members will also rotate in fixed position with respect to the member, due to the action of centrifugal force. However, When the rotation is diminished suiciently, the weighted members will drop out of the notches and will fall into some one of the other notches arbitrarily. Through the action of gravity, the weighted member will cause the member B to seek its lowest level, and this in turn will cause a corresponding character to become aligned or framed within the Window i6. If desired, the weights may be different in the various members B and this will cause the various rotatable members to stop their rotation in the order desired.

In order to start rotation, a handle 26 is provided outside of the end i3, having a recessed shaft 21 extending through the standard il and adapted to receive one end of the shaft A'. The inner end or the shaft 2l is provided with a crank arm 2t, which is adapted to abut against and partially rotate a crank 29, Xedly secured to the shaft A'. 'Ihe opposite end of the shaft A' is provided with a compression spring 3l), adapted to abut against the standard i2 and permit the entire shaft, with the members B, to be shifted slightly to the left, as viewed in Fig". 3. The standard H is provided with a fixed cam 3i, over which the crank 29 must ride when driven by. the handle crank `28. The shaft A is further provided with a fixed crank 32, which is connected to the standard i?. by means of a tension spring 33. Thus, it will be understood that when the Vshaft A is turned counterclockwise, as viewed in Fig. through the action of iol crank 28 against crank 29, the movement will be against the tension of spring 33. As the rotation is continued, 4the crank 23 will ride up on cam 3|, causing the shaft A to shift and compress spring 3D. The cam 3| thereby causes the crank 29 to separate from the crank 28 until the crank 29 slips over the widened beveled portion 34 of the crank 28. When this occurs, the spring 33 will cause the shaft A to rotate violently in the opposite direction. In starting the cranking action, the handle 26 is first rotated clockwise sufficiently to pass beneath and beyond the crank 29. Thus, it will be understood that the beveled portion S4 in this movement will again move the shaft against the compression of spring 3U suiiiciently to permit the cranks to get into the position shown in Fig. 4. The standard is provided with a stop 35 for the crank 29, anda stop 36 for the crank 28, at the starting position just described.

As shown in Fig. 3, the members B are arranged in pairs, with studs 2| extending toward each other. Between each pair of members, is provided a crank 31, fixed to the shaft A by means of a set'screw 3B. Near the end of the crank, is a forked driving arm 39, which is pivotally secured to the crank by means of a pin 40. The crank 31 is provided with a notch 4|, so that the driving arm 39 can make but limited movement with respect thereto. The end of the driving arm has a curved contact portion 42, which is adapted to engage studs 2|. Normally, the crank 31 is held up in the position indicated in Fig. 5, and through the action of gravity the driving arm 39 swings back out of the path of the studs 2|, so that the members B may rotate freely. However, when the shaft is cranked up by means of the handle 25, the crank 31 swings downwardly and the contact portion 42 swings into the path of the studs 2| and will exert a quick driving action on them as soon as the shaft is released.

To operate the device, the handle 26 is rotated clockwise` as far as it will go. which will bring it into the position shown in Fig. 4. The handle is then turned in the opposite direction until it is automatically released and the shaft, through the crank 31 and driving arm 39, will swing in the opposite direction with considerable force under the action of spring 33 and cause the rotatable members to spin. The spring 33 will cause the crank 31 to assume the position shown in Fig. 5 and will not interfere with the turning movement on the members B. When the rota tion of the members B is diminished sufficiently through the action of friction, the weighted members C will tumble out of their sockets and drop arbitrarily into the same or other sockets and thereby cause the characters to become aligned with the window i6, when the movement stops.

The foregoing detailed description is given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in View of the prior art.
