Abstract: A coloring device for transferring coloring materials from a writing or drawing instrument to a surface is disclosed. The coloring device includes a housing having a holder to hold a writing instrument, and, a roller connected to the housing for rotation about an axis. The roller is position to contact a writing instrument disposed in the holder to obtain coloring material therefrom and is further positioned to contact a surface to transfer the coloring material obtained from the writing instrument thereto as the roller rotates about the axis. In accordance with one optional aspect of the invention, the coloring device can be further provided with means for rotating the roller. These means may comprise a motor, a hand crank, or any other equivalent structure that can impart rotational motion to the roller. If the means for rotating is excluded, the roller is rotated by moving the coloring device such that the roller rolls against the surface to be marked.

Abstract: The toy combination includes a toy vehicle having one or more pairs of spaced apart shoulders on exterior sides of the vehicle body and one or more toy attachments releasably secured on the pairs of shoulders by snap-fitting a respective pair of rails on the toy attachment against a respective pair of shoulders. The toy attachment includes resilient extensions on which the rails are carried. The extensions are flexed to snap-fit the rails on the shoulders. The toy attachment can include first and second pairs of extensions adjacent opposite ends with a receptacle intermediate the extensions for releasably receiving a toy figure.

Abstract: The toy combination includes a self-powered toy vehicle with driven wheels adjacent the front thereof and a toy trailer with non-driven wheels and with a receptacle on the trailer in front of its wheels releasably receiving the rear of the toy vehicle. The toy vehicle and trailer include cooperative details for locating and interlocking them together when the rear of the vehicle is received in the receptacle. The toy vehicle and trailer are configured such that the toy combination formed thereby resembles a tractor-trailer type truck whose front wheels comprise the driven wheels of the toy vehicle and whose rear wheels comprise the wheels of the trailer.
