Abstract: A drawing device adapted to produce line drawings or sketches on a transparent screen on top of a case partly filled with a powder that adheres slightly to the undersurface of the screen to render it opaque. Disposed within the case are transverse and longitudinal rods operatively coupled to respective control knobs, one of which, when turned, causes the longitudinal rod to shift toward either side of the case, the other of which, when turned causes the transverse rod to shift to either end of the case. Supported at the intersection of the rods is an indexable stylus turret and carrier assembly whose carrier is slidably supported on the transverse rod and whose stylus turret which is received within the carrier, is slidably supported on the longitudinal rod whereby the position occupied by the assembly is determined by the point of intersection. The turret is indexable to present to the underside of the screen, for scraping powder therefrom to draw a line, any one of three styluses each producing a line of different width or character or to present a blank stylus which interrupts the drawn line. Indexing is effected by pressing an actuator bar operatively coupled to the longitudinal rod carrying the turret to depress this rod and to cause a turret pin to engage an abutment in the carrier, this action causing the turret to index to its next operative position.

Abstract translation: 一种绘图装置，其适于在透明屏幕上在部分填充有粉末的情况下在透明屏幕上产生线条图或草图，所述粉末略微粘附到屏幕的下表面以使其不透明。 设置在壳体内的横向和纵向杆可操作地联接到相应的控制旋钮，其中一个在转动时使纵向杆朝向壳体的任一侧移动，另一个在转动时使横向杆移动到 案件的任何一方。 在杆的交叉处支撑是可转位的触针转盘和支架组件，其托架可滑动地支撑在横杆上，并且其托架中的触针转塔被可滑动地支撑在纵向杆上，由此组装所占据的位置是 由交点确定。 转台可转位以呈现在屏幕的下侧，用于从其上刮下粉末以画一条线，三个指示笔中的任何一个都产生不同宽度或字符的线，或者呈现中断绘制线的空白触笔。 通过按压可操作地连接到承载转台的纵向杆的致动器杆来实现转位，该致动器杆压下该杆并且使转塔销接合支架中的支座，该动作导致转塔向其下一个操作位置进行转位。

Abstract: A hand-propelled toy airplane, locomotive or other wheeled vehicle for pre-school children having a handle making it possible for a player to push the vehicle along a surface. The vehicle is provided with one or more lights whose bulbs are connected to a battery supply through a handle switch that is actuated only when the player grasps the handle to turn on the lights. Operatively coupled to the axle of a wheel set is an interrupter switch connected in series with the handle switch, the circuit arrangement being such that when the handle switch is actuated, at least one light goes one, and when the vehicle is pushed along the surface, the actuated interrupter switch then causes the lights to turn on intermittently to produce a blinking effect at a rate depending on how fast the vehicle is being propelled. When the handle switch is released by the player, the battery supply is disconnected from the bulbs, so that no power is drained from the supply when the toy is not in use.
