The devices normally draw concentric rectangular, spiral, or circular patterns on the surface by manual manipulation of a pencil or like marking device guided by the perforated bars or rings. The present invention is designed to provide a power operated o. mechanized designing toy for drawing a predetermined pattern on a marking surface, and the device has means facilitating selection of various patterns to be traced thereby.
An object of the present invention, therefore, is to provide a mechanized drawing device of the character described and, particularly, one which includes a frame power-motive means for moving the frame over ,a marking surface in a given direction or path, interrupting means associated with the power-motive means for intermittently moving at leasta portion of the frame out of the given path or to change the direction or path, and marking means mounted on at least the aforesaid portion of the frame to trace the pattern of movement of that portion onto the marking surface. In the embodiment illustrated herein, the power-motive means moves the frame in a generally straight path and the interrupting means is operative to permit intermittent movement, at equal intervals,
of said portion of the frame out of the given path in a different but constantly the same direction so as to trace a concentric pattern.
Another object of the invention is to provide a drawing device as set forth in the preceding paragraph in which the interrupting means may be changed selectively to vary either the interval or duration, or both, of the interrupting function thereof thereby to permit varying the pattern.
A further object of the invention is to provide a drawing device of the character described inwhich the power-motive means includes a plurality of movable members mounted on the frame for powered movement over the marking surface and all of the members cooperating to move theframe in the given direction or path of travel. The interrupting means is operative to intermittently render at least one but not all of the movable members inoperative to move at least a portion of the frame intermittently out of the given directionof travel. The marking means is mounted on at least that portion of the frame. In the embodiment illustrated herein, the movable members comprise a pair of generally parallel wheels mounted on the lower portions of the frame for powered movement over the marking surface and the interrupting means is operative to intermittently raise one of the wheels out of engagement with the surface whereby the frame intermittently pivots thereabout.

FIG. 6 is a schematic view showing a drawn pattern at the left in FIG. 6 as effected by a cam disc having the shape shown at the right in FIG.- 6.
DETAILED DESCRIPTION OFTHE INVENTION The drawing device of this invention is shown herein as incorporated in a self-containedpower operated mechanized unit which is designed to ride overand upon a marking surface to draw patterns on that surface corresponding to the path of movement of at least a portion of the device and having means permitting the user to selectively change the path of movement of the device. For illustration purposes, the device is shown in the form or configuration of a mechanical man which moves over the drawing surface, allof which will be described in greater detail hereinafter.
Referring to the drawings in greater detail, themechanized drawing device of the present invention, generally designated 10, includes a generally hollow frame havinga head portion I2, a body portion 14 and a pair of hand or arm portions 16. The hand or arm portions 16 each-have a vertical cylindrical sleeve portion '18 which receives and holds marking means such as pencil or felt or ballpoint pen 20 to move the marking means or pen over a marking surface 22 to draw the pattern of movement of thatportion of the frame on which the pen is mounted as the 'frame moves over the marking surface by power-motive means described below. In addition to the hand or arm portions 16, a plurality of outwardly projecting boss portions v24 may be formed on the body portion 14 of the frame, with vertical cylindrical bores 26-formed in the boss portions 24 to receive additional marking pens to enhance-the capability of the device to draw a wide variety of patterns on the marking surface 22. As seen in FIG. 1, marking pens 20 may have washerlike members 28 positioned thereabout to seat on top of the sleeveportions 18 or the boss portions 24 to prevent the marking pens from falling therethrough should the device be lifted off of the marking surface 22.
A power-motive'means is provided to move the frame and marking, pens overthe marking surface in a predetermined pattern and includes a battery operated conventional motor 30 (FIGS.v 2'and 3) which works off of a pair of dry-cell batteries 32 (FIG. 4). To facilitate a self-contained unit, preferably both the motor 30 and the batteries 32 are disposed within the hollow head and body portions 12 and 14, respectively. A pair of spaced, generally parallel rubber-treaded wheels 34 are mounted on the lower body portion 14 of the frame on an axle 36 for powered movement over the marking surface 22 by the motor 30 through a gear train, generally designated 38. The
An interrupting means is associated with the power-motive means (motor 30, wheels 34, etc.) for intermittently changing direction of the device or moving at least a portion of the device out of the straight-line direction or path of movement. The interrupting means includes a jack member 43 (as best illustrated in F IG. pivotally mounted at point 44 on the body portion 14 of the frame adjacent one of the wheels 34 (the right-hand wheel as viewed in FIGS. 1 through 3). The jack member 43 has a downwardly depending portion 46 which engages the marking surface 22 and an upwardly extending cam follower portion 48 which engages the periphery of cam disc 50 which is rotated by motor 30 through the gear train 38, as best seen in FIGS. 2 and 3. The cam disc 50 is slidably mounted on the end of a shaft 52 which has a gear member 54 fixed thereto and in operative engagement with a gear member 56in the gear train 38. As best seen by the cam discs shown in FIGS. 1 and 6, each cam disc has a plurality of rises and falls about the periphery thereof on which ride the cam follower 48 fixed to the top of the jack member 43. As a rise on the periphery of the cam disc 50 rotates into engagement with the cam follower 48, the rise biases the jack member 43 downwardly to the position shown in FIG. 5 in full line. In that position, cam disc 50 has lifted the adjacent wheel 34 off of the marking surface 22 whereby the device is caused to pivot about about the depending potion 46 of the jack member 43 as the opposite wheel continues to rotate and as the cam disc 50 continues to rotate until the cam follower reaches a lower point on the periphery of the cam disc to lower the adjacent wheel 34 back into engagement with the marking surface 22. The device then will resume its given direction or path of travel, a straight path herein.
HO. 6 shows by way of example one pattern which is drawn by the particular cam disc 50 shown therein by using the device of the present invention. That pattern is formed by using a single marking pen 20. By using additional marking pens, still further patterns are formed by using a single cam disc 50.
An important feature of the instant invention is the replaceability of the cam discs 50 to permit selection of an experimentation with various patterns. As seen in FIGS. 2 and 3, the drive-shaft member 52 for the cam discs 50 has an irregularly shaped end 60, such as a hexagonal shape, which slidably receives the cam discs 50, each of which has a complementary bore or recess. Each disc has a handle portion 62 to facilitate shows in phantom a raised or upwardly pivoted position of the retaining member 64 to facilitate access to the cam disc 50 and to permit the cam disc to be slidably removed from the end 60 of the drive shaft 52. When a cam disc is properly placed on the shaft 52, the retaining member 64 is lowered by gravity so that an annular housing portion 64a seats over the cam disc 50 and prevent the cam disc from sliding off of its drive shaft 52.
' The foregoing detailed description has been given for clearness of understanding only and no. unnecessary limitations should be understood therefrom as some modifications will be obvious to those skilled in the art.
