Application June 24, 1954, Serial No. 438,978

18 Claims. (Cl. 273-95) This invention relates to a game device and more particularly to an airplane bombing game wherein toy airplanes are rotated about a central tower and bombs are dropped from these planes by remote control.

One object of this invention is to provide a game in which toy planes are revolved around a central pylon and bombs are released from these planes by remote control.

Another object of this invention is to provide a plurality of planes revolving about a pylon on 'difi'erent levels so that bombing planes on the upper levels may drop bombs on the lower or target planes by remote control.

A further object is the provision of a game device as described above wherein the bombing plane may be remotely controlled to vary the position of the plane on its carrying member.

Yet another object is the provision of a game device of the above type wherein the target planes are caused to rise and fall and turn loops as they revolve about the pylon.

This bombing game comprises one or more bomb dropping airplanes mounted on one or more rotary arm assemblies which are moved around a pylon tube by means of la drive shaft extending centrally throughout the length thereof. The pylon tube is centrally mounted on a base which may have any desired type of decoration thereon. The drive shaft is driven by a small electric motor mounted on the base. A plurality of control levers, which are independently operable, are positioned on the base and through suitable means act to tilt the planes carried on the rotary arms so as to drop the bombs carried by the planes. A plurality of target planes are carried on radially extending arms below the bombing planes. These radially extending arms are attached to a ring gear which is rotated by gear means engaging the drive shaft which revolves the rotary arm assemblies. In addition operating and control means are included for positioning the bombing planes along the length of the arm carrying them.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, wherein:

Fig. 13 is a side elevation showing a bomb with its supporting hooks slanting beyond the vertical axis; and

Fig. 14 is a side elevation showing a bomb with its supporting hooks slanting forward of the vertical axis.

As shown in Figs. 1, 3 and 5, the bombing game comprises a base board 10 having a supporting frame 12 extending downwardly therefrom to position the base above the surface on which it is carried. A pylon tube 14 is mounted centrally on the base 10 in line with hole 11 therein by means of a threaded flange 16 engaging the threaded bottom portion of the pylon and secured to the base by suitable bolt and nut means. A cap 18 is mounted over the top of the pylon tube 14 and is adapted to slide up and down between the positions indicated in solid and dotted lines in Fig. 3.

An electric motor 20 of the type commonly used in window displays is mounted on the bottom of the base directly beneath the pylon tube 14 by means of brackets 22. A sleeve connector 24 connects the motor with drive shaft 26 extending centrally upward through pylon tube 14-. This drive shaft extends above the upper end of the pylon tube and is connected to a rotary arm assembly 28. This assembly comprises a central arm 30 which is attached to drive shaft 26, and has a tube 32 rotatably carried thereover. The outer end of arm 30 is threaded to receive a nut to retain the rotatable tube 32 in place. This tube is held in position on the inner end by means of a disc 34 which is attached to the arm 30. This disc has a peripheral cutout portion 36 in which rides a stop pin 33 attached to tube 32. A frictional sleeve element 40 is fitted on the periphery of the inner end of the tube 32 and is adapted to be engaged by the top surface of eap 18 when it is raised to the position indicated in dotted lines in Fig. 3.

Referring to Figs. 1 and 8, bombing plane 42 has a hole 44 extending transversely through the lower portion of the fuselage 46. Tube 32 extends through this hole to position the plane on the rotary arm assembly 28. This tube has a line of small indentations 48 extending along its forward face which are adapted to be individually engaged by a spring pressed ball 56 carried in the fuselage to hold the plane in position thereon. Thus, the plane may be manually traversed along the length of tube and held in the desired position. This means also serves to provide enough frictional engagement between the tube and the plane to cause the plane to tilt as the tube is rotated about arm 30.

As shown in Fig. 11, a bomb 52 in the form of a dart is held on the bottom of the fuselage 46 by means of a pair of hooks 54 and eyes 56. This arrangement is also shown in Fig. 9.

Referring to Figs. 3 and 5, the control means for causing the plane to tilt forwardly and drop the bomb comprises a rotatable control shaft 58 fitted at its outer end with a crank handle 59 extending through and exposed above the base as seen in Fig. 1. The shaft is suitably carried by brackets 60 and has a crank 62 at its inner end which is pivotally connected to vertically reciprocating rod 64 extending upwardly through the pylon 14 into contact with the underside of the cap 18. Any number of control assemblies may be used depending on the particular needs; however, four disposed at 90 intervals is considered adequate. A pair-of bushings 65 are positioned within the pylon 14 and have holes therein adapted to guide the rods 64 and drive shaft 26 within the pylon. The position of these members is shown in Fig. 7. I

Electric motor which actuates the device is geared to drive at slow speed and is supplied power by electric line 66 controlled by switch 68 as indicated in Figs. 1 and 5.

The operation of the apparatus thus far described is as follows. Switch 68 is turned on to supply power to motor 20 to cause drive shaft 26 to rotate in a counterclockwise direction. This causes the rotary arm assembly 28 carrying the plane 42 to travel in the same direction over the base 10. When it is desired to drop a bomb on the base, control handle 59 is pushed clockwise to operate crank 62, thus causing rod 64 to rise and lift cap 18 into contact with frictional sleeve element 40. Since tube 32 is revolving about the pylon 14, contact of sleeve 40 with the top of non-rotatable cap 18 will impart rotary motion to tube 32 about central arm 30. This motion will cause plane 42 to tilt nose downwardly and thereby cause bomb 52 to slip from eyes 56 and fall on the base 10. The rotation of tube 32 about arm 30 is controlled by stop pin 38 riding against the ends of peripheral cutout 36. As shown in Fig. 6, the stop pin 38 is in the position wherein the plane is tilted nose downwardly. The plane returns to a generally level position under the force of gravity when cap 18 is lowered out of contact with sleeve element 40. The plane is placed on the tube 32 in such a manner that there is an unbalance, the heavier portion being at the rear to thereby cause the plane to return to horizontal position.

Although this device has been described and illustrated as having only one rotary arm assembly 28, it is obvious that a plurality of such units could be used. In addition more than one plane may be positioned on each rotary arm assembly. A rotary arm assembly having two planes thereon at the same angle of inclination is shown in Fig. 9.

In connection with the arrangement wherein more than one plane is positioned on each rotary arm assembly, the planes may be so mounted that the bombs dropped therefrom will fall at intervals. This may be accomplished by varying the angle of attack of the airplanes with respect to the horizontal so that upon the tilting of the planes the bomb or bombs will be freed from one plane and then upon further tilting the bombs on the next plane will be released. This same result could be achieved by varying the angle of the bomb carrying means either on the same plane or different planes.

This arrangement wherein the hooks by which the bombs 52 are held in eyes 56 are positioned in varying angles with respect to a vertical axis is shown in Figs. 11, 13 and 14. Fig. 11 shows the bomb 52 with the hooks 54 in a vertical position, while Fig. 13 shows the hooks 55 in a position slightly beyond the vertical axis and Fig. 14 shows the hooks 53 in a position slightly forward of the vertical axis.

As shown in Fig. 1 a plurality of target planes 90 are carried on a level below that of the bombing plane 42. The arrangement illustrated includes four radially extending arms rotatably carried about the lower portion of the pylon. Any number of planes may be mounted on these arms. This particular arrangement is shown in detail in Figs. 1, 2, 3 and 4 as follows. 1

A collar 70 is secured to pylon 14 by means of set screw 72 and acts as a bearing to support a rotatable sleeve 74. Four brackets 76 extend radially outward from the upper end of the sleeve and each has a pair of spaced vertically extending guides 78 positioned on the outer end thereof. A ball member 80 of a ball and socket type joint is mounted on the upper face of each bracket adjacent the guides 78. A socket member is fitted over ball member 80 and is held in place by screw 84. This socket member is attached to a rod 86 which is in turn secured to a large wooden arm 88 adapted for carrying of planes 90 as indicated in Fig. 1. U-shaped supports 92 are attached to rod 86 and carry rollers 94 which ride on the upper face 97 of a cam 96. This cam is somewhat hemispherical in shape having an undulating upper face 97 and a hole in its lower center portion which is of suflicient diameter so that it will fit over the pylon 14. The cam is secured to flange 16 by means of screws 98. t

The arms 88 are rotated about pylon 14 by gear means whose power is derived from motor 20 which also operates the upper plane arrangement. A driver gear 100 is attachd to drive shaft 26 and drives idler gear 102 which in turn engages internally toothed gear 104 carried on and affixed to radial brackets 76 by means of screws 106. An opening 108 is cut in the wall of pylon 14 to accommodate the gearing described above and also to allow access to the structure within the pylon.

Referring to Figs. 2 and 3, idler gear 102 is mounted on a shaft 110 attached to the wall of the pylon. The upper portion of this shaft is threaded to receive a nut 112 adapted to hold the idler gear in position, as shown in Fig. 2. The teeth of idler gear 102 are shrouded at the top and the shroud engages the top face of the teeth on ring gear 104 so as to exert a downward force to act as the means for holding this entire lower rotating assembly in position. The manner in which the shroud of gear 102 overlies the teeth of gear 104 is shown in Fig. 4.

In operation, driver gear 100 rotates counterclockwise and through idler gear 102 imparts clockwise rotation to gear 104 thereby rotating the sleeve 74 and the arms carried thereon in a clockwise manner. The ball and socket mounting of arm 88 combined with riding of the rollers 94 over the undulating cam face 97 produces up and down and tilting motion to the planes carried on arms 88 as they rotate about the pylon 14.

A modification of the bombing game is shown in Figs. 9, 10 and 11 and includes means for remotely controlling the position of the bombing planes on the carrying arm and also another means for tilting the planes to cause the bomb to be dropped. Means for causing the target planes to do loops is also included in this embodiment.

This modification embodies the same general structural elements as the first embodiment wherein the pylon 14 is secured to the central portion of base 10 which is in turn supported by frame 12. A centrally apertured vertically slidable cap 18 is positioned over the top end of pylon 14. The electric motor 20 drives shaft 26 by means of sleeve 24. The drive shaft extends centrally throughout the length of pylon 14 and is connected to a rotary arm assembly 28. This assembly comprises a central arm 30 attached to drive shaft 26 and tube 32 rotatably carried thereon. A spring arm 114 is secured to tube 32 adjacent the inner end thereof in such a manner that the lower end of the arm will just touch the top face of cap 18 when the cap is in its lowermost position as shown in Fig. 9.

The control means for tilting the planes carried on tube 32 are similar to those of the first embodiment to lift reciprocating rod 64 within the pylon 14 into contact with the underside of the cap 18.

Raising of cap 18 causes tube 32 to be rotated through spring arm 114 thus tilting the planes carried thereon and dropping the bombs. As in the first embodiment a pin and slot arrangement may be used to limit the rotation of tube 32. However, in this instance it is not actually necessary to the successful operation of the device.

In order to position the planes 43 along the length of tube 32 this device is provided with a line and pulley arrangement controlled by suitable remote means. As shown in Fig. 9 a pulley 116 is secured to the end of arm 30 and is adapted to cooperate with a driving pulley 118 freely carried on drive shaft 26. Pulley 118 has a downwardly extending spool-like portion 120 which has a conical recess 122 in its bottom. This recess 122 is adapted to cooperate with the conical member 124 which is a part of gear 126 to form a clutch 127 between pulley 118 and gear 126. The conical member 124 and gear 126 are also freely carried on drive shaft 26. A washer 128 is secured on shaft 26 to act as the lower retaining means for the gear 126 and the apparatus thereabove. The engaging pressure of the clutch elements is eifected by a coil spring 132 compressed between the upper face of pulley 118 and washer 134 secured on shaft 26. Gear 138 engages gear 126 and is carried on a shaft 140 extending downwardly through pylon 14 to slightly below the base. A bevel gear 142 is carried on the lower end of shaft 140 and is adapted to be engaged by bevel gear 144 which is normally disengaged therefrom. Gear 144 is carried on rod 146 which has a crank and a handle 148 secured to the outer end thereof. Bevel gear 144 is held out of engagement with bevel gear 142 by means of coil spring 151) which fits over rod 146 and rides against

collars

152 and 154 which are secured to the base and rod 146 respectively.

A braided wire or cord 152 is passed around pulleys 116 and 118 to form a complete loop. Referring to Figs. 9 and 11, planes 43 are slidably carried on tube 32 and have clips 154 thereon to secure one side of the looped cord 152 thereto. The other side of the loop is adapted to ride in a transverse groove 156 in the lower portion of the fuselage 46.

In normal operation, drive shaft 26 will be rotating, thus causing the rotary arm assembly 28 to rotate about the pylon 14. The clutch 127 is frictionally adjusted by spring 132 so that gear 126 and pulley 118 will turn with the drive shaft 26 through frictional engagement of clutch 127 and that between gear 126 and washer 128. Since gear 126 is in engagement with gear 138 the latter will rotate shaft 140 and bevel gear 142. With the device in operation as described, engagement of gear 144 with bevel gear 142 by pushing inwardly on rod 146 and not rotating the rod will result in relative rotation of gear 126 and pulley 118 about shaft 26 through slippage between 122 and 124 and thus cause the cord 142 to be moved and traverse the planes in one direction along the length of the tube 32. To move the planes in the opposite direction shaft 146 is pushed in and the crank 143 turned in the proper direction to overcome the speed of rotation of gear 142.

In order to traverse the planes along tube 32 when the rotary arm assembly is not rotating, rod 146 is pushed inwardly so that bevel gear 144 engages gear 142 and upon rotation of rod 146 gear 144 rotates gear 142 which in turn rotates shaft 149 and gear 138, thus turning gear 126 which through clutch 127 rotates pulley 1118 thereby moving cord 152 and changing the position of the planes secured thereto The clutch 127 is quite useful in that upon reaching the end of free movement in either direction additional rotation of gear 126 merely results in slippage of clutch 127.

As in the first embodiment, a plurality of target planes are carried on a level below that of the bombing planes 43. This arrangement is best shown in Fig. 9 and as before includes four radially extending arms rotatably carried about the lower portion of the pylon.

A'rotatably mounted sleeve 74 fits over the lower portion of pylon 14 and has four brackets 76 extending radially outward from the upper end thereof. A pair of spaced vertically extending guides 78 are positioned on the outer end of the brackets and act as guides for rod 86 mounted on the support by ball and socket means. So far this arrangement is exactly like that shown in Figs. 3 and 4. Rod 86 carries a rotatably mounted tube 158 which is adapted to have one or more target planes secured thereto in the same general manner as those shown in Fig. l. The outer surface of the tube 158 near its inner end rides on the upper face 97 of cam 96. As best shown in Fig. 2 this cam has an undulating surface 97 which imparts up and down movement to the planes carried on tubes 158. At the same time the frictional engagement of the outer surface of the tube 158 with the cam face 97 causes the tube to rotate about rod 86 and thereby causes the planes to do likewise. By this arrangement the planes rotate about the pylon in a rising and falling manner and also turn what might be called loops.

As shown in Fig. 12, rod 162 is secured to and extends outwardly from rotatable tube 158 and swivelly carries target plane 9% by means of swivel 164. By so mounting the target plane, it is capable of performing many types of acrobatics such as spinning, looping and diving. Obviously the length of the rods 162 can be varied to achieve various formations and dispositions of the target planes.

The means for rotating the sleeve 74 and all the apparatus carried thereon is exactly like that of the first embodiment which has been previously described and shown in Figs. 2, 3 and 4.

The overall action produced in this second embodiment is quite varied. The bombing planes 43 swing around the pylon and may be remotely controlled to move inwardly or outwardly along the arms on which they are carried and may also be tilted by remote control to drop bombs at the desired instant. While this is going on the target planes on the lower level are swinging around the pylon in a rising and falling manner and are also doing acrobatics. The further modification shown in Fig. 12 makes it possible for the target planes to perform an even greater number of different types of acrobatics.

The base 11} may be decorated or ornamented in any suitable manner to facilitate the game.

In view of the above it is apparent that there has been produced a bombing game having a number of interesting functions including the romote controlling of the position of the planes and also of the bombing action. A device such as this is suitable for use in the home as a game device or could readily be adapted for use in a coin operated game of skill.
