MECHANICALLY OPERATED FLUID DISPENSING DEVICE May 21, 1963 2 Sheets-Sheet 2 Filed Oct. 27, 1960 FIG.6
INVE NTOR RONALD ELLIS ATTOR NEY Unite It has been known for some time that foot-pedal operated dispensers are particularly desirable for dispensing fluids such as skin cleansing liquids; this is particularly true in the case of medical work, such as surgery, where the hands of the operator should be isolated as far as possible. The object of the present invention is to provide a food-pedal operated fluid dispenser which is readily applicable to use in medical work.
Other objects of the present invention reside in the provision of a dispenser which is mechanically operable in such a way as to completely avoid the necessity of touching the same by the human hand, and having a remote operated device which will uncap the dispenser, cause dispensing of fluidmaterial therein in a predetermined location, and then cause the cap to be replaced correctly to again close the dispenser, all without manual contact by the operator, and including means for the remote operation as for instance a foot treadle or the like which may be pedally actuated in order to cause operation of the dispenser for the intended purpose.
Further objects of the invention include the provision of a support which may be standard mounted or wall mounted or in any way desired, such support providing means mounting a squeeze bottle type dispenser in verti cal upside down position, with the closed cap thereof extending downwardly, in combination with means for operating the cap to open and close the bottle in relationship with an actuator to apply pressure to the squeeze bottle to cause expulsion of material therein in a desired location, together with remote operated means as for instance, e.g. a foot treadle or the like mounted in convenient position so that the operator may actuate the cap and bottle merely by pressing the treadle, or other means, without touching the same with the hands or using the hands in anyway, whereby the hands are kept in the sterile condition desired but still supplied with the fluid.
The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.
Reference is to be had to the accompanying drawings, in which FIG. 1 is a view in side elevation showing the invention;
FIG. 2 is a view in front elevation on an enlarged scale, looking in the direction of arrow 2 in FIG. 1, parts being omitted;
FIG. 3 is a section on line 3-3 of FIG. 2;
FIG. 4 is a view in elevation, looking in the direction of arrow 4 in FIG. 1, illustrating the return spring;
FIG. 5 is a bottom plan view, looking in the direction of arrow 5 in FIG. 1, and on an enlarged scale;
FIG. 6 is a section on line 6-6 of FIG. 1, also on an enlarged scale; and
FIG. 7 is a view similar to FIG. 1 with parts removed and illustrating the device in operative condition.
In carrying out the invention, the reference character 10 indicates a wall or an upright standard of any kind desired on which the parts may be conveniently mounted, and the reference character 12 indicates the floor line. Mounted at a suitable height on the wall or standard 10, there is a bracket which may comprise if desired a pair of legs 14 and 16, these being spaced and parallel and outstanding in a horizontal direction from the wall 10. A
rates Patent 0 3,090,528 Patented May 21, 1953 ice similar pair of legs 18 and 20 may also be provided in downwardly spaced relation from legs 14 and 16. These four legs mount at their outer ends a generally flat plate indicated at 22. This flat plate has an aperture therein at 24 generally in the upper portion thereof for a purpose to be described, and it also has a lower slot 26. This slot 26 accommodates a cap-gripping member for the dispenser squeeze bottle 28 which bottle is principally held in a band or other bracket 30 mounted on plate 22. The squeeze bottle is provided with a neck 32 and a spout 34, this spout being covered by a removable cap 36 which closes the spout in FIG. 1.
The neck of the container 32 may be removably clamped in position by a bar 38 mounted to pivot at 40 on a small upright member 42 also mounted on plate 22. The bar 38 is provided with a thumbpiece 44 and it has a portion which is reentrantly bent as indicated at 46, see particularly FIGS. 3 and 5, to engage with a turned-over portion 48 on a small upright 50, the latter also being mounted on plate 22 at the opposite side of the slot '26 from upright 42. By pivoting the piece 38 as indicated by the arrow in FIG. 2, the squeeze bottle maybe released and a new one replaced and held in the bracket.
The cap 36 is removed by means of a piece generally indicated at 52. This piece has four spaced arms, one pair at 54 at one side of the cap flange or head 56, and the other pair of arms corresponding but opposite at 58 at the other side of the cap head or flange. These arms are all mounted on a standard or the like indicated at 60 and they surround the cap head or flange 56, holding it. Standard 60 is pivoted on upstanding cars 62 on a pivot 64, the ears 62 being conveniently mounted on plate 22 and the member 60 being in the form of a lever extending through the slot 26.
It will be seen that when this member 60 is pivoted as a lever in a clockwise direction in FIG. 1, i.e., downwardly, the cap 36 is removed, see FIG. 7, and when the lever 60 is moved in the opposite direction, the arms 54 and 58 will cause the cap to be repositioned on the dispensing spout 34, closing it.
The member 60' forms a part of a member 66, and member 66 is pivoted at its inner or lower end at 68 to a block 70 on which is mounted a bumper member 72 which may be conveniently made of any desired material but preferably rubber. The block 70 is mounted and supported on an elongated rod 74 which extends downwardly to a type of bell crank lever 76 having a footoperated member 78. When the member 78 is stepped upon, the bell crank 76 moves in a clockwise direction in FIG. 1, as shown by the arrow which causes rod 74 to move upwardly, thus causing block 70 to move upwardly, and inwardly, as shown in FIG. 7, actuating member 60 to remove the cap 36, and thereafter, in timed relation, to extend through the aperture 24, contacting the under side of the squeeze bottle and expressing the contents therefrom through the now-open spout at 34. A spring construction of any desired means such as is indicated at 80 may be utilized to aid gravity in bringing the parts to the original closed position.
In the operation of the device, when the operator steps upon the lever 78, the cap is almost immediately removed due to the fact that the block 70 causes lever 6d, 66 to move in a clockwise direction in FIG. 1, and taking with it the cap 36, this opens the spout. At an interval of time thereafter, the block 72 will extend through the aperture 24 and impinge upon the squeeze bottle to expel the part of the contents therethrough through the now-open spout, it being observed that the spout is clearly open and interval of time before the squeezing operation takes place. Conversely, when the operator removes the foot from pedal 78, the squeeze bottle operating block will first be removed therefrom so that expulsion of the contents will be stopped and then the cap is thereafter re-applied to the spout due to spring 80.
An adjustable stop 82 .is provided comprising an adjustment screw having a head 84 and a nut 86 mounted on a plate 83 so that the creturn action of spring 80 will cause the cap opening means 69, etc. to return the cap to the correct degree. In other words, the screw may be adjusted so that the springs will position the cap on the spout 34 in substantially the correct closing position therefor to avoid leakage from the bottle. Also guideplates 94 and 92 may be utilized for the upright rod 74 and these guide plates provide a convenient mount for the reaction point forthe spring 85) indicated at 94.
It will be seen that this invention provides a dispenser which is operated Without being touched by the hands in any way so that one may sterilize the hands and then obtain a desired amount of fluid material from the squeeze bottle for whatever purposes may be desired without touching anything with the hands but using only the foot.
