- the rear side or wall I0 of the conical shaped portion 68 may be sloped more nearly toward the horizontal than the forward portion thereof for a purpose subsequently to be described, and is provided with asl'ot H that communicates with the opening 59 so as to receiveand constitute a stop for the arm 55 of the rod 53 when the latter is moved to its extreme upward position, as shown in Figure 4; and to permit loop 54 to pass through and come to rest above the level of the air or gas opening 69.
- the slot 1! may be provided with a rubber insert so as to cushion the movement of the rod and absorb the shock so that the liquid film on the loop will not be jarred off.
- the horizontal portion 51 of the rod 53 when the latter is in its lowermost positiori,'passes through a slot 12 on the front side of the spout 49 to establish a clearance therewith, and the vertical portion 58 extends downwardly through the spout While the horizontal portion 59 extends longitudinally through the tunnel 52 so as to be pivotally connected by the portion 6'! to the bracket 5!.
- a flexible rod or wire 13 is connected at its forward end to the diaphragm plate 30 by the bolt 35 and has a loop or book 74 at its opposite end through which loosely extends the portion 59 of the bubble releasing rod 53,- so that movement of the plate 30 and membrane 32 by rotation of the crank shaft l1 will cause simultaneous movement of the rod 53 about the pivotal connection of the portion 51 with the arms 63 and 64 of the bracket 6
- may have a vertical discharge opening 15 which communicates with the compressed air ohamber 4'! and is closed by a screw or plug 16 (Fig. 3). After a long interval of time, and probably only after rough handling of the toy, enough bubble liquid might have become splashed over into the compressor chamber 4'!
- the toy boat may be pushed or pulled along the ground or other fiat surfaceand, as shown has a cord or string 1'! connected as at" "to the front of the hull in order to be conveniently pulled by a child.
- the bottom shell 43 bftlrereservoir is of substantial area in order to receive an ample supply of liquid bubble solution 19 u to a height that Will not reach the topof nipple 48, the latter being well below the top of spout 49 such that the liquid cannot overflow into the air compressor chamber 41, and the reservoir is so constructed and arranged as to essentially prevent spilling or leaking of the bubble solution therefrom, either into the air compressor chamber 41 or else external to the boat.
- the rod 13 is moved from the position shown in Figure to that disclosed in Figure 4 so as to simultane ously cause the rod 53 to swing about its'pivot portion 61 and raise the loop 54 upwardly through or over the opening 69 and this movement is limited by engagement of the arm 55 with the cushion in the slot 'H in the conical portion III of the shell 44 so that the parts assume the position as shown in Figure 4.
- the loop 54 moves upwardly from the reservoir through the opening 69, it carries a film of the bubble solution therewith.
- the operation of the compressor 41 and the bubble releasing rod 53 are so synchronized that when the loop passes through the opening 59, the compressed air discharged into the reservoir chamber causes a bubble to be formed which is quickly released from the loop.
- the rod 73 is slidably and operatively connected to the rod 53 in such a manner as to operate the looped end portion 54 in synchronism with the compressor.
- this movement together with the forward tipping of the plate 30, as a result of the crank shaft i1 lifting rearwardly of the center of the plate, causes loop 54 to r'me suddenly due to the upward pressure exerted by the rod 13 against the portion 59 of the rod 53.
- the loop 54 arrives and remains at its uppermost position (Fig.4), while the loop or hook it on the rod l3 slides rearwardlyand the flexible rod '13 is moved upwardly so as to assume a nearly straight shape as shown in Figure 4. Further, the loop 54 is movedto its lowermost position for reloading when no air is being compressed in the chamber 41. Toward the end of the downstroke: of the plate 30, the loop 54 suddenly drops for reloading so that it is practicable with this arrangement to maintain the loop in its uppermost position for about of the operating cycle.
- the sharp inclination of the rearwall 10 of the conical portion 58 provides means for preventing the bubbles, as they are formed, from breaking against this wall and to clear the same in a region of the best or maximum air flow.
- the design offered for the portions 58, in and 44 serves the purpose not only of simulatin a Smokestack but also of providing an annular cavity or vessel about the air opening 69 and at a difierent vertical level from it such that if the toy is invertedv the annular space will be below the air opening 63, thus preventing spillage of bubble liquid ex ternal to the device.
- the width and length of the slot H is necessarily kept small and restricted.
- air from this slot tends to bend the main air beam forward, thus the plane of the air opening 69 may be tilted rearwardly in order to oppose and neutralize the bending effect of the jet of air from the slot H.
- the forward motion of the boat tends to cause the same to run into the emerging bubbles 80 and this may be avoided by proper tilting of the plane of the air opening 69.
- the loop 54 will cause formation of a small bubble at the surface of liquid pool within the area defined by the loop when the latter is raised from the surface of the reservoir or when it is dropped into the reservoir, and so as to form foam which will cover the entire surface of the reservoir.
- the nipple 48 fills up the space where the foam-forming bubbles tend to be created, with the result that the formation of such foam is substantially reduced.
- the nipple 43 also serves the purpose of orienting or aligning the loop 54 prior to anchoring the bracket iii to the underside of the shell 50.
- the spout i9 is of such a length as to extend appreciably above the liquid level of the bubble solution is in the reservoir so as to reduceor prevent suction of foam into the compressor chamber 41 and to prevent loss of liquid from the reservoir into the compressor.
- are preferably made of wood or other light durable material While the shells 43 and 44 may be cast of plastic or pressed from a plastic sheet and cemented or welded at the adjoining lips 42.
- Metal sheets such as iron or aluminum, can also be pressed to form the shells 43 and 44 and soldered, welded or folded at the adjoining lips :32.
- the perforated bottom cover plate 38 permits unhampered compressor operation and is provided to enhance the appearance of the boat and to protect the membrane 32 and V the crank mechanism.
- bubble mechanism while shown associated with a toy boat, may be with equal efficiency installed on other devices and types of toys of various sizes, shapes and designs either movable or stationary, handpowered or motor-driven, so as to provide simple, efiicient and attractive mechanical means for producing bubbles in a sanitary manner and which does not require frequent reloading.

The present invention relates to mechanical bubble blowing devices and, more particularly, to a new and improved means for producing bubbles.
An important object consists in providing a toy, such as a boat, train or the like, with simple, eflicient and economical means intermittently operable to form and release bubbles as the toy is moved along the ground or other flat surface.
A further object is to provide a bubble boat toy with means including an air compressor, a liquid reservoir, a bubble releasing mechanism having a looped member arranged to alternately be dipped into the bubble solution in the reservoir and be moved adjacent an outlet air opening in the top of the reservoir. The air compressor and bubble releasing mechanism may be operatively connected to a driving shaft that, in turn, is rotated by the ground-engaging wheels of the toy and the parts are so synchronized that the looped member of the bubble releasing mechanism is moved adjacent the air opening at the same time as the air is forced from the compressor through the air opening, so that the film of bubble solution on the looped member is formed into numerous bubbles which are discharged from the toy as the latter is pushed or pulled along the round.
Another object comprehends the provision of a bubble blowing device which avoids the unsanitary and mechanically dangerous act of blowing via the mouth through a stem held to the lips, as is required with many bubble blowing devices, and the only human factor involved being that of pushing the toy along the floor or other surface by hand or else pulling with a string. On the other hand, a motor, such as a spring motor, can be employed in the toy to provide completely automatic operation, here again retaining sanitary and safe operation.
A still further object is to provide a bubble blowing mechanism which can be adapted by anyone of normal mechanical skill to a stationary form and which can be operated by any suitable means such as an electric motor, the resulting arrangement serving for purposes of decoration or general attraction, such as when employed as an amusing table-piece in a night club or as an attractive mantel or wall attachment.
An additional object is to provide a toy such as a boat or a train which is capable of interesting action and simulates after a fashion an observable action of a real machine, such as the substitution of clusters or puffs of bubbles for puffs of, smoke.
Also, an object is to provide a bubble blowing toy from which the bubble liquid cannot be spilled by ordinary handling or inverting of the toy, thus preventing loss of liquid as such and also preventing damage to clothing or furniture, the latter condition permitting safe operation of the toy indoors. Furthermore, as in the case of the bubble boat, the toy can be employed as a pulltoy for very young children and as a push-toy for somewhat older children, thus providing a toy that will serve a reasonably wide age group.
Other objects and advantages of the invention will be apparent from the following description when taken in conjunction with the accompanying claims and drawings.
Referring to the drawings in which is shown, for illustrative purposes, one form my improved bubble toy may assume:
Figure 1 is a perspective view of a toy boat con structed in accordance with the invention.
Figure 2 is a plan view of Figure 1 with the cover or Smokestack removed.
Figure 3 is a longitudinal sectional view taken substantially along the 'line 3-3 of Figure 2 and showing the bubble releasing mechanism in its lowermost position with the smoke stack in place.
Figure 4 is a view similar to Figure 3 and showing the bubble releasing mechanism in its raised position.
Figure 5 is a sectional View taken substantially along the line 5-5 of Figure 3, and
Figure 6 is a sectional view taken substantially along the line 66 of Figure 3.
Referring to the drawings in which like numerals indicate like parts in the several views, [0 designates a childs toy which, for the purpose of illustration, is shown in the form of a boat having a hull or base II that is formed with an elongated opening i2 (Fig. 3) and the spaced parallel sides l3 (Fig. 2) having reduced or cut-away portions I4 for receiving the ground-engaging wheels l5 and I6. A crank shaft I! (Fig. 5) has an intermediate offset portion l8 which is connected to the horizontal end portions I9 by the bent portions 20. The end portions l9 extend transversely through bearings 2| fixed or otherwise secured to the sides [3 of the hull and constitute axles for the wheels [5 and [6. At least one of the wheels, such as I5, is keyed or otherwise non-rotatably connected to the shaft I! so as to rotate the drive shaft I! when the toy is pulled or pushed along the ground. The ends of the shaft H are provided with suitable means for retaining the wheels on their axles and for looking at least one of the wheels to the axle, and the attachment device consists of or is covered by caps 22 or other means and so shaped as to provide suitable appearance, to prevent marring of furniture or scratching the body of the operator. Recesses 23 and 24 are formed in the underside of the hull at the front and rear thereof so as to receive rollers 25 which are journalled in the recesses by the rods or pins 26. The wheels I and I6 and rollers 25 preferably are provided with rubber tires 21 so as to protect the surface over which the toy is moved and insure proper driving traction for the wheels.
An elongated block 28 which may constitute a lower deck or cabin is mounted on the hull I I and has an elongated opening 29 that registers with the opening I2 in the hull or base II (Fig. 4). A
. diaphragm or compressor plate 32 (Fig. 4) having a central elongated slot 3| is arranged to be vertically displaceable within the openings I2 and 2!) in the hull II and lower deck 28, and is spaced from the inner walls of these openings so as to be moved or rocked therein. A flexible, pneumatically tight, waterproof membrane 32, preferably of rubberized nylon, extends over the upper surface of the plate 30 and the slot 3I (Fig. 3) so as to project outwardly thereof and has a loose marginal outer portion 33 of such size and dimension as to be clamped around its edge between the hull II and the deck 28 as at 34, in order to form a pneumatic sealed anchorage continuously around the juncture of the walls of the openings I2 and 29. The intermediate portion of the flexible membrane 32 may be cemented to the top of the plate 30 or else clamped to the plate by a sheet of fiber (not shown) or other suitable material having the same shape and size as the plate and being held thereto over the membrane by the bolts or rivets 35. The intermediate offset portion I8 of the shaft II'I extends transversely below the plate 30 so as to movably engage the bottom of it (Fig. 5) and impart a vertical reciprocating or rocking movement to the plate when the crank shaft is rotated by the wheels during the operation of the toy. A crank strap 33 extends longitudinally of the slot 3| and below the offset portion I8 of the shaft I] so as to be movably engaged by the latter. The ends of'the strap 36 may be secured to the underside of the plate 30 by the bolts or rivets 35 which also hold the sheet-like membrane clamp, providing the membrane is not otherwise attached, such as by cementing to plate 30. The offset portion I8 of the crank shaft I1 is preferably provided with spaced annular rings or washers 3'! which are soldered or otherwise secured thereto and extend into the opening 3I of the plate 39.
Alternatively, a thin metal spool can be placed over the shaft section l8 and secured thereto by wings pinched on the shaft at each end of the spool. The spool or rings 37 are spaced so as to engage opposite sides of the strap 36 for the purpose of properly positioning the plate 32 in order that the inclined portions 28 of the crank shaft I1 do not engage the plate 30 toward the middle of the downstroke of the crank shaft when the latter is rotatedby the wheel I5. The opening 35 in theplate 30 provides a clearance for the rings or washers 37 when the toy is in operation. A
boat. The block III is formed with an opening or hollow portion 42 (Fig. 4) which registers with the opening 29 in the lower block or deck 28, and these blocks may be secured to each other and to the base or hull I I by any suitable retaining means to provide a fluid tight seal, such as screws or the like, not shown.
A bubble fluid reservoir or container including a lower shell 43, preferably of any suitable light durable metal, is positioned in the opening 42 of the upper block or deck 4! and is closed by an outer shell 44 which preferably is shaped in the form of a smokestack or funnel. The shells 43 and 44, around their outer edges, are provided with abutting outwardly extending flanges 45 and 46, respectively, which may be welded or otherwise secured together and fastened to the block 4| adjacent the wall of the opening 42 so as to provide a tight seal. The bottom shell 43 is spaced from the plate 30 and the flexible membrane 32 and coacts therewith to form a compressed air chamber 4! in which is movable the plate 30 and the loose portion of the membrane 32, so as to constitute a diaphragm or bellowstype compressor that is operated by rotation of the crank shaft I! when the wheels I5 and I6 are moved along the ground. The bottom of the shell 43 adjacent the forward end thereof is provided with an upwardly extending protuberance or nipple 48 (Fig. 4) and with a spout 49 that is spaced laterally or longitudinally from the nipple 48. Also, the bottom of the shell 43 has extending rearwardly from the spout 49 a raised portion or plateau 58 (Fig. 4) that is divided or separated longitudinally by a centrally disposed raised portion 5| (Fig. 5) that forms a tunnel 52 for a'purpose subsequently to be described.
A bubble releasing mechanism preferably including a stiff wire or rod, generally designated 53 (Fig. 4), is formed at its outer or front end with a loop 54 preferably but not necessarily circular. The rod 53 has extending rearwardly from the loop 54 a horizontal arm portion 55 bent upwardly as at 56, then bent horizontally at 51 and downwardly at 58, then longitudinally and rearwardly at 59, laterally as at 6!] (Fig. 6), so
- ing arm 63 and a spaced depending arm 64 having a greater length than the arm 63 and bent,
upwardly as at 65 (Fig. 6) to form a spaced outer arm 66. The lateral portion 60 of the rod 53 is bent 'so as to provide a rear end portion 61 which "extends transversely through aligned openings in the arms 63 and 54 so as to be pivotally connected to the bracket in order to allow the loop 54 to be swung vertically by the pivotal connection of the end portion 61 with the bracket 6|.
i The loop 54, when in its lowermost position (Fig.
3), is arranged to rest on the bottom of thev shell or reservoir 43 so as to surround or enclose the nipple 48. The upper shell 44, which is preferably shaped to form a stack or funnel, is
pressed inwardly to provide a conical or truncatbottom-cover 38 preferably provided with perforations or air holes 39 (Fig. 4) may be secured to the underside of the base or hull I I by suitable retaining means, such as the screws 40 (Fig. 5), so as to protect the membrance 32, crank mechanism and their associated parts.
A block 4I, preferably of the shape shown in Figure 1, is superimposed on the block 28 so as to simulate in appearance the upper deck of a toy ed portion 68 which at its apex has an air opene ing 69 (Fig. 3) substantially in vertical alignment with the nipple 48 but spaced therefrom so as not to interfere with the free flow of air or gas through the opening 69. The rear side or wall I0 of the conical shaped portion 68 may be sloped more nearly toward the horizontal than the forward portion thereof for a purpose subsequently to be described, and is provided with asl'ot H that communicates with the opening 59 so as to receiveand constitute a stop for the arm 55 of the rod 53 when the latter is moved to its extreme upward position, as shown in Figure 4; and to permit loop 54 to pass through and come to rest above the level of the air or gas opening 69. The slot 1! may be provided with a rubber insert so as to cushion the movement of the rod and absorb the shock so that the liquid film on the loop will not be jarred off. The horizontal portion 51 of the rod 53, when the latter is in its lowermost positiori,'passes through a slot 12 on the front side of the spout 49 to establish a clearance therewith, and the vertical portion 58 extends downwardly through the spout While the horizontal portion 59 extends longitudinally through the tunnel 52 so as to be pivotally connected by the portion 6'! to the bracket 5!. A flexible rod or wire 13 is connected at its forward end to the diaphragm plate 30 by the bolt 35 and has a loop or book 74 at its opposite end through which loosely extends the portion 59 of the bubble releasing rod 53,- so that movement of the plate 30 and membrane 32 by rotation of the crank shaft l1 will cause simultaneous movement of the rod 53 about the pivotal connection of the portion 51 with the arms 63 and 64 of the bracket 6|. The upper deck 4| may have a vertical discharge opening 15 which communicates with the compressed air ohamber 4'! and is closed by a screw or plug 16 (Fig. 3). After a long interval of time, and probably only after rough handling of the toy, enough bubble liquid might have become splashed over into the compressor chamber 4'! via spent 49 to accumulate in an amount siiflicirit to make its removal desirable, this being accomplished by removal of drain plug 16 and the rearward tipping of the boat to' providedrainage. The toy boat may be pushed or pulled along the ground or other fiat surfaceand, as shown has a cord or string 1'! connected as at" "to the front of the hull in order to be conveniently pulled by a child. The bottom shell 43 bftlrereservoir is of substantial area in order to receive an ample supply of liquid bubble solution 19 u to a height that Will not reach the topof nipple 48, the latter being well below the top of spout 49 such that the liquid cannot overflow into the air compressor chamber 41, and the reservoir is so constructed and arranged as to essentially prevent spilling or leaking of the bubble solution therefrom, either into the air compressor chamber 41 or else external to the boat.
' In operation, assuming that the reservoir 43 is filled to the desired level with a liquid bubble solution 19 and the diaphragm 30 and membrane 32are in their lowermost position, as shown in Figure 3, the loop, 14 on the rod 13 will then slide forwardly so as to cause the horizontal portion-51 of the rod 53 to be moved downwardly into the slot 12 on the spout 49 and the loop 54 to rest on the bottom or floor of the reservoir and encircle the nipple 48. As the toy moves forwardly,- the movement of the drive wheels l5 and i5 imparts rotation to the shaft I! which now has its intermediate offset portion It in its lowermost position as shown in Figure 5, and continued rotation of the shaft and the engagement of the portion l8 with the underside of the plate 30 raises the latter together with the membrane 32 so as to compress the air or gas in the chamber 41 and force the same outwardly through the spout 49 into the reservoir where it discharges through the air opening 69. "Simultane'ously with this upward movement, the rod 13 is moved from the position shown in Figure to that disclosed in Figure 4 so as to simultane ously cause the rod 53 to swing about its'pivot portion 61 and raise the loop 54 upwardly through or over the opening 69 and this movement is limited by engagement of the arm 55 with the cushion in the slot 'H in the conical portion III of the shell 44 so that the parts assume the position as shown in Figure 4. As the loop 54 moves upwardly from the reservoir through the opening 69, it carries a film of the bubble solution therewith. The operation of the compressor 41 and the bubble releasing rod 53 are so synchronized that when the loop passes through the opening 59, the compressed air discharged into the reservoir chamber causes a bubble to be formed which is quickly released from the loop. When the offset portion 18 of the shaft reaches its uppermost position, the loop 54 is moved slightly above the opening 59 so as to insure the Withdrawal of the formed bubble 80 without danger of impinging against the conical wall 58, and the reduced slope of the rear side 15 of the conical wall will further prevent the bubble from be ing broken by contact with the shell 44. On the downstroke of the crank shaft H, the plate 35 and membrane 32 are moved downwardly by rea son of the engagement of the strap 35 with the ofiset portion l8 of the shaft l1, and the connection of the rod 13 with the rod 53 causes the lattear to be lowered and the loop 54 to rest on the bottom of the reservoir and enclose the nipple 48. At the same time, air is sucked in through the openings 69 and spout 49 into the compressor chamber 41 so as to be compressed upon the upstroke of the crank shaft l1.
It will be noted that the rod 73 is slidably and operatively connected to the rod 53 in such a manner as to operate the looped end portion 54 in synchronism with the compressor. In other words, as the plate 30 moves upwardly from its lowermost position, this movement together with the forward tipping of the plate 30, as a result of the crank shaft i1 lifting rearwardly of the center of the plate, causes loop 54 to r'me suddenly due to the upward pressure exerted by the rod 13 against the portion 59 of the rod 53. As the plate 30 continues to rise, the loop 54 arrives and remains at its uppermost position (Fig.4), while the loop or hook it on the rod l3 slides rearwardlyand the flexible rod '13 is moved upwardly so as to assume a nearly straight shape as shown in Figure 4. Further, the loop 54 is movedto its lowermost position for reloading when no air is being compressed in the chamber 41. Toward the end of the downstroke: of the plate 30, the loop 54 suddenly drops for reloading so that it is practicable with this arrangement to maintain the loop in its uppermost position for about of the operating cycle. The sharp inclination of the rearwall 10 of the conical portion 58 provides means for preventing the bubbles, as they are formed, from breaking against this wall and to clear the same in a region of the best or maximum air flow. The design offered for the portions 58, in and 44 serves the purpose not only of simulatin a Smokestack but also of providing an annular cavity or vessel about the air opening 69 and at a difierent vertical level from it such that if the toy is invertedv the annular space will be below the air opening 63, thus preventing spillage of bubble liquid ex ternal to the device. V
vIn order to keep outflow-ing air in a beam-like path lying along the axis of the conical member 68, so as to prevent the bubbles from breaking upon the wall thereof, the width and length of the slot H is necessarily kept small and restricted. In other words, air from this slot tends to bend the main air beam forward, thus the plane of the air opening 69 may be tilted rearwardly in order to oppose and neutralize the bending effect of the jet of air from the slot H. The forward motion of the boat tends to cause the same to run into the emerging bubbles 80 and this may be avoided by proper tilting of the plane of the air opening 69. If the nipple 48 in the bottom of the reservoir is omitted, the loop 54 will cause formation of a small bubble at the surface of liquid pool within the area defined by the loop when the latter is raised from the surface of the reservoir or when it is dropped into the reservoir, and so as to form foam which will cover the entire surface of the reservoir.
The nipple 48 fills up the space where the foam-forming bubbles tend to be created, with the result that the formation of such foam is substantially reduced. The nipple 43 also serves the purpose of orienting or aligning the loop 54 prior to anchoring the bracket iii to the underside of the shell 50. The spout i9 is of such a length as to extend appreciably above the liquid level of the bubble solution is in the reservoir so as to reduceor prevent suction of foam into the compressor chamber 41 and to prevent loss of liquid from the reservoir into the compressor. The hull II and decks 28 and 4| are preferably made of wood or other light durable material While the shells 43 and 44 may be cast of plastic or pressed from a plastic sheet and cemented or welded at the adjoining lips 42. Metal sheets, such as iron or aluminum, can also be pressed to form the shells 43 and 44 and soldered, welded or folded at the adjoining lips :32. The perforated bottom cover plate 38 permits unhampered compressor operation and is provided to enhance the appearance of the boat and to protect the membrane 32 and V the crank mechanism.
It will be understood that the bubble mechanism, while shown associated with a toy boat, may be with equal efficiency installed on other devices and types of toys of various sizes, shapes and designs either movable or stationary, handpowered or motor-driven, so as to provide simple, efiicient and attractive mechanical means for producing bubbles in a sanitary manner and which does not require frequent reloading. Further, the form of the invention shown and described is merely illustrative and such changes may be made as come within the scope of the following claims.
