ApplicationApr-il 3; 1934, Serial 1No.: 71 8,853 3:1?
2 Claims.v ..,(Cl. 68-15) between the walls of the tub in a manner-to use the agitatorfor washing purposes.
A further object of the invention is to provide" an attachment having in addition to the above enumerated elements suitable pump means-for during operation of the agitator.
A still further object of .the invention is to providean attachment of this character'which is economical in construction and operation; and
in stationary tubs as are for themost part only enjoyed by users of power driven-washing: machines.
The invention together with its objects and ad= vantages "will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:
Figure 1 is a top plan view illustrating the application of the invention.
Figure 2 is a vertical sectional view, certain parts being shown in elevation and other parts broken away.
Figures 3 and 4 are sectional views taken substantially on the lines 33 and 44 respectively of Figure 2.
Figure 5 is a sectional View taken substantially on the line 5-5 of Figure 1, and
Figure 6 is an enlarged View through the agitator, agitator rod and swivel connection between said rod and the conduit leading from the pump, certain parts being shown in elevation and others broken away and shown in section.
Referring to the drawings by reference numerals it will be seen that 10 indicates generally one section or part of a stationary Wash tub, although it is to be understood that it is not in any wise intended to limit the invention to use with this particular type of tub.
The device per se comprises a supporting frame consisting of relatively fixed side members 11-11 and relatively slidable side members or sections 1212 that are non-circular in cross section and have slidable engagement with elongated noncircular sockets 13 provided in one end of the side sections 11.
At the other end thereof the sections 11 have hinged or pivoted thereto as at 14 clamps 15 that are adapted to straddle the upper edge of one side wall of the tub, and these clamps are provided with securing screws 16 as shown. The side secforcing air under pressure into the washing water which will give the user advantages in washing" tions 12attheir'free ends are provided with clamps 17 similar-to clamp- 15 and these clamps '17 are also provided with thumb screws l8.
Mounted on'the supporting frame is a platform or carriage 19 andmounted on the carriage is an 5 electric motor20, a bearing block '21, guide frame 22, a pump 23, and a pedestal 24 for the pump.
'The base ofthe motor 20 is secured to the platform 19 "through the-medium of bolt and nut means-25; 26. The-pedestal-for the pump 23 is secured to the platform 19 through the medium" of bolt'and nut means Z'T'and it will be seen that ';.the bolts 26; 27 operate in slots 28 provided therefor inthe side members 'll'of the frame. Thus it. will be seen that the platform 19 may be-adjusted longitudinally of the frame for centering the agitator, as may be required to meet I the adjustments ofthe"supportingframe-neces-- sary to mount the device on the tub; In this connectionit will'beunderstood-that these tubs vary in size, and that from the above provision has been amply made to meet the requirement of the particular tub with which the device is to be used.
As clearly shown in Figure 4 there are journalled in the bearings of the block 21 shafts 29, 30 and on one end of these shafts are gear wheels 31 that are in constant mesh with a pinion gear 32 on the armature shaft 20a of the motor 20.
Also mounted on the shafts 29, 30 are segmental spiral gears 33 that are adapted to alternately mesh with a spiral gear wheel 34 that is suitably secured to the agitator shaft 35. As clearly shown in Figure 3 the agitator shaft 35 is journalled in a bearing 36 rising from the platform 19 and in a bearing 37 provided in the top portion of the guide frame 22. The shaft 35 is held against vertical movement through the medium of the hub 34d of the gear 34 resting on the upper end of the bearing 36 and a collar 38 suitably secured to the shaft beneath the platform 19.
From the description thus far it will be seen that drive is transmitted from the motor 20 through the gearing 31, 32 to the shafts 29, 30, and by reason of first one gear 33 meshing with the gear 34 and then a second gear 33 meshing with the gear 34 oscillatory movement is imparted to the agitator shaft 35, it being apparent that through the provision of the gearings 33, 34 said shaft 35 is first rotated in one direction and then in a reverse direction as indicated by the arrows in Figure 4.
The lower end of the agitator shaft 35 is threaded to screw threadedly receive the collar 39 with which the agitating blade 40 is equipped.
As before intimated the pump 23 is provided for forcing air under pressure into the water and in the preferred form of the invention the outlet side of the blower 23 is provided with a conduit 41 that at its free end is swivelly connected as at l2 with the upper end of the agitator shaft 35. Shaft 35 as shown in Figure 6 is hollow to provide an air conduit that is in line with an air conduit 43 provided in any suitable manner in the blade 48 and opening a'd'jacent the lower edge of the blade at opposite sides of the blade through the medium of the outlet passage 44. It will thus be seen that air under pressure will be forced from the pump 23 through the conduit ll, the agitator shaft 35 and the air passage 43 in the blade to discharge therefrom through the passage 44 at opposite sides of the blade during the operation of the agitator.
For driving the pump 23 there is suitably mounted on one end of the shaft 29 a gear 45 that is in mesh with a pinion gear 46 provided on one end of the fan shaft of the blower. Obviously during operation of the agitator pump 23 will operate for forcing air downwardly through the agitator shaft and into the washing water at opposite sides of the agitator 40.
It will be apparent that when it is not desired to use the attachment, instead of removing the attachment wholly from the tub thumb screws 18 may be loosened, clamps l7 disengaged with one edge of the wall of the tub and the entire attachment then swung to one side about the pivots of the hinges 14.
Having thus described my invention, what I claim as new is:
1. An attachment of the class described comprising a supporting frame provided with means for engaging opposite walls of a tub to support the frame transversely of the tub, a platform slidably mounted on the supporting frame, an agitator shaft extending vertically through the platform, bearing means for the agitator shaft, said agitator shaft being hollow, an agitator blade mounted on the lower end of the shaft and having an air passage extending therethrough in line with the agitator shaft, and a discharge passage for the air passage opening at opposite sides of the blade; a pump for supplying air mounted on the platform having a discharge conduit leading therefrom, a swivel connection between said discharge conduit and the upper end of the agitator shaft, and means common to the agitator shaft and said pump for simultaneously driving the same.
2. An attachment of the class described comprising a supporting frame provided with means for engaging opposite walls of a tub to support the frame transversely of the tub, a platform slidably mounted on the supporting frame, an agitator shaft extending vertically through the platform, bearing means for the agitator shaft, said agitator shaft being hollow, an agitator blade mounted on the lower end of the shaft and having an air passage extending therethrough in line with the agitator shaft, and a discharge passage for the air passage opening at opposite sides of the blade; a pump for supplying air mounted on the platform having a discharge conduit leading therefrom, a swivel connection between said discharge conduit and the upper end of the agitator shaft, and means common to the agitator shaft and said pump for simultaneously driving the same, said driving means including means for rotating the agitator shaft first in one direction and then in a reverse direction for oscillating the agitator blade.
