J anuary. 6, 9 .8, Seria N91 (i1 that may be operatedby v 7 Various v es hav ee rrqvidsd $91- f ai 1 ing films of liquid adapted to form b b l through a. current of air so thatbubblesfare a formed from the liquidbut these a je DrQVided as separate units, or are comparatively complicat d so that they are not adapted for universal use. With this thought in mind this inventionconw templates a comparatively simple unidue casing having a solution compartment with a fan and disc in combination therewith, and a crank for rotatingthe fan and disc through gears wherein the disc turns slow and the fan relatively fast.
The object or this invention is, therefore, to
provide a unique hand operated mechanically actuated bubble making machine wherein a single crank operates a bubble d sc. at sl w sp ed and a fan at comparatively high speed.
Another object of the invention is to provide a mechanically actuated bubble maker in which the parts may readily be cleaned.
A further object of the invention is to provide a mechanical bubble making machine which is of a simple and economical construction.
With these and other objects and advantages in View the invention consists of the new and novel combination, construction, and arrangement of parts as hereinafter more fully described, set forth in the claims appended hereto, and disclosed in the accompanying drawings forming part hereof, wherein:
Figure 1 is a view showing a side elevation of the mechanical bubble blowing machine.
Figure 2 is a view showing an end elevation of the machine with a part broken away.
Figure 3 is a similar view looking toward the opposite end of the machine.
Figure 4 is a plan view of the machine.
Figure 5 is a longitudinal section through the machine taken on line 5-5 of Figure 3 with the fan, gears, and gear support shown in elevation.
Figure 6 is a cross section through the discharge end of the machine taken on line 6--6 of Figure 5, showing the bubble carrying disc.
Figure7- is a cross section through the machine taken on line L-Tof Figure. 5 showing theair scoop." Figure 8 is a cross section through the machine taken on line 8-8 of Figurefi showing the'ge'ars and fan.
Figure 9 is a detail showing a plan view of the gear train and. fan'with parts broken away and d. i 1 V v" Referring "now to the drawings wherein like reference characters dehot'ecorresponding parts the bubble blowing InachiheOf this "invention includes a'casing we ving a centrallydis posed horizontal shaft in with a fan :2 and a tame disc l3thereori, and a crank [4,] H In the design shown the casing is in the form of a cylinder witl'i'supports I5 on the lower'side; a perforated head lfijwith an elongated slot l1 therein, through which the uiextends, at
. one end, and with a'solutioh compartment l8 in the lower end formed bet weer'ran endlg'anda partition 2Q; resend i9" is provided "with" a transverse outwardly fiared flange 2'! whichfa cilitates pouring solution into the compartment 8. and in the upper part of-the end is an opening 22 with an arcuate flange 23 having a taperupper edge which catches the drip from ex ces's fluid onthebubbles and provides a drain therefor back tothe compartment I8. The end plate Hl is provided withfilling openings 24am} 25 and the" compartment 18 is filled until the liquid flows through these openings, and in the upper part of the partition is an orifice 26 that is positioned to register with opening 21 in the bubble disc I3, as shown in Figure 7. The partition 20 is also provided with an arcuate web 28 which forms an air scoop that catches the air and directs it through the orifice 26.
The outer end of the shaft II is journaled in the partition 20 and the opposite end is rotatably mounted in flanges 29 and 3d of the gear support 31 which is mounted in the casing at the points 32 and 33, as shown in Figure 8. The crank I l is mounted on the end of a jack shaft 34 which is ourna-ed in the flange 30 and also in an intermediate flange 35, and the jack shaft 34 is provided with a gear element having a gear 36 and a pinion 31 which is fixedly mounted on the shaft. The pinion 3T meshes with a gear 38 having a hub 39 through which it is fixed on the shaft H by a set screw 40, and as the crank is turned the shift [I is rotated at comparatively slow speed so that the disc l3 on the outer end of the shaft turns at slow speed.
The gear 36 meshes with a pinion 4| of a gear 42 that is freely carried by the shaft H, and the gear 42 meshes with a pinion 43 of a gear 44 that is freely mounted on the jack shaft 34. The gear 44 meshes with a pinion 45 on a sleeve 46 which forms the hub of the fan l2 and with the hub freely rotatable on the shaft II, the fan will be rotated at comparatively high speed. The gear support is provided with a bar 41 which supports the intermediate flange 35, as shown.
With the parts arranged in this manner the compartment l8 may be filled with a soapy solution or the like, and as the crank M is turned the fan and disc [3 will be rotated and as the disc rotates it will pick up a film of the liquid which will cover the openings therein and the air from the fan will blow through the openings forming the film into bubbles which will float from the machine.
It will be understood that any suitable solution may be used and also that modifications may be made in the design and arrangement of the parts Without departing from the spirit of the invention.
What is claimed is:
1. A bubble blowing machine comprising a cylindrical casing having a solution compartment in one end, a longitudinally disposed centrally positioned shaft journaled in the'casing, a disc having openings spaced from the periphery mounted on the shaft and positioned in the said solution compartment whereby the peripheral edge thereof passes through the lower part of the compartment as the disc rotates with the shaft, a sleeve rotatably mounted on said shaft, a fan in the intermediate part of the casing carried by the sleeve and positioned to blow air through the openings of the disc and through the upper part of the solution compartment, and means rotating the fan and disc with the speed of the fan being greater than that of the disc.
, 2. A bubble blowing machine comprising a cylindrical casing having a solution compartment in one end, a longitudinally disposed centrally positioned shaft journaled in the casing, a disc having openings spaced from the periphery mounted on the shaft and positioned in the said solution compartment whereby the peripheral edge thereof passes through the lower part of the compartment as the disc rotates with the shaft, a sleeve rotatably mounted on said shaft, a fan in the intermediate part of the casing carried by the sleeve and positioned to blOW air through the opening of the disc and through the upper part of the solution compartment, a gear train positioned in the casing and rotatably connecting the sleeve to the shaft, and a hand crank extended from the casing for rotating the shaft and disc through the gear train.
3. In a mechanically actuated bubble blowing machine, the combination which comprises a cylindrical casing having a transverse partition spaced from one end providing a solution compartment between the partition and end of the casing, the opposite end of said casing being perforated and the said partition and end of the casing from which the partition is spaced having aligned openings therethrough, a longitudinally disposed shaft journaled in the casing, a disc having openings spaced from the periphery mounted on the shaft and positioned in the said solution compartment whereby the peripheral edge thereof passes through the lower part of the compartment as the disc rotates with the shaft said openings of the partition and end of the casing being in register with the opening through the disc, a jack shaft also journaled in the casing and spaced from the longitudinally disposed shaft, a, sleeve on the longitudinally disposed shaft having a fan on one end thereof, a train of speed changing gears mounted on the jack shaft, the longitudinally disposed shaft and sleeve, and a hand crank extended from the end of the jack shaft for rotating the longitudinally disposed shaft with the disc carried thereon and the sleeve with the fan carried thereon with the fan rotating at a speed greater than that of the disc, said fan positioned to blow air through the openings through the partition, disc and end of the casing.
