' 1 Claim.
This invention relates to a brush and particularly pertains to a hand brush of thefountain type in which the brush back of handle is hollow and forms a reservoir for a liquid soap.
Heretofore brushes of this character have been devised primarily with the view of effecting delivery of a liquid soap directly to the bristles of I the brush, and accordingly such devices usually involve a valve controlled discharge outlet or nozzle arranged to direct the soap on or into bristle tufts carried by the brush back or handle.
An object of the present invention is to provide a fountain brush in which the point of discharge of' soap from a reservoir in the brush back or handle is located apart from the bristles and at a point such that the soap may be conveniently deposited in the palm of the hand, or on any other surface apart from the brush or the bristles thereof, so that the operator may observe the amount of soap delivered, thus enabling avoidance of waste of the soap as may be frequently occasioned where the soap is delivered to the bristles since the volume of soap so delivered is not readily apparent.
An advantage attained by positioning the point of discharge apart from the brush bristles is that the soap may be deposited directly upon the surface on which it is to be used so that it will be subject to being immediately acted on by the tips of the bristles and without the delay incident to the fiow of the soap along the lengths of the bristles and the infiltration of the soap throughout the base portions of the bristle tufts where it is not needed as is occasioned where the soap is initially delivered to the base of the bristle tufts.
A further object is to provide a control valve construction in a fountain brush which is operable on manipulation of the brushin a manner to actuate the valve by imparting an impact thereon to effect ejection of a spurt of soap from a discharge orifice.
With the foregoing objects and advantages in view, together with such other objects and advantages as may subsequently appear, the invention is carried into way of example in the accompanying drawing, in which:
Fig. 1 is a perspective view of the brush;
Fig. 2 is a view in longitudinal section showing the brush as up-ended in a position occupied when effecting discharge of the liquid soap, and
I showing the control valve in its closed position;
Fig. 3 is a perspective View depicting the maneffect as illustrated by g ly from the wall ner' of manipulating the brush in effecting discharge of its liquid soap content;
Fig. 4 is an enlarged detail in section of the control valve structure, showing the valve in an open position.
Referring to the drawing more specifically 6 indicates generally a hollow brush back or handle which is here shown as conventional shape for grasping in the hand or bythe fingers, and which is fitted with a group of bristle tufts I in a usual manner.
one end of the hollow back 6 is formed with a filler opening 8 fitted with a closure plug 9 here shown as screwed therein, and through which opening a liquid soap Ill may be delivered to the reservoir ll formed interiorly of the back 6.
In carrying out the invention the bristle supporting wall i2 of the back 6 is formed adjacent an end margin thereof with a discharge orifice l3 which leads from the reservoir II at an end thereof and opens contiguous to but spaced from adjacent bristle tufts I in an end row thereof with at least a portion of the orifice disposed in the area of the wall l2 extending between the end margin thereof and the adjacent end row of bristle tufts as shown'in Fig. 4.
Extending transversely of the orifice I3 is a bore 14 which opens through the adjacent end l5 of the back 6 and in which is mounted for longitudinal reciprocal movement a piston I8 formed with a head ll which is spaced outward- I5. A spring 18, here shown as wound around the outer portion of the piston I6, bears between the wall I5 and the head I1 and acts to normally maintain the piston E6 .in an outermost position with a port IS in the piston disposed out of register with the orifice l3 and in the end wall 15.
The head I1 is fitted with a curved stem 20 which projects inwardly and outwardly from the head and extends into a slot 2| formed by a bracket 22 carried on the end wall l5, which stem and slot construction serves to hold the piston against turning and also limits outward movement thereof under the urge of the spring l8.
The bore I4 is of sufficient length to afford a space between its inner end and the inner end of the piston and provide clearance so that the piston may be advanced to position the port l9 therein in register with the orifice 13.
Leading from the inner end of the bore [4 to the reservoir II is an aperture 23 through which fiuid may pass from the bore [4 into the reservoir H on inward movement of the piston and may fiow from the reservoir into the bore on outward movement of the piston.
In the operation of the invention the brush back is grasped in one hand and upended to position the pLu'np head I! downward as shown in of the hand, or against any other surface as illustrated in Fig. 3 so as to advance the piston l6 upwardly in the bore l4 and thereby bring the port I 9 into register with the orifice l3 as shown in Fig. 4 so that liquid will flow to discharge through the port l9 and orifice-l3, the liquid thus being directed outwardly and downwardly as indicated by the arrows in Fig. 4 clear of the bristle tufts l and thereby beapplied directly to the palm of the hand or to whatever surface as may be arranged beneath the orifice l3. 1
Upward movement of the piston l6 forces liquid from the bore l4 through the aperture 23 into the reservoir. On release of the pump head from inward pressure thereon, the spring I8 will expand and retract the piston so as to close the orifice I3.
By the construction and arrangement shown, the operation of the pump piston above described may be rapidly effected so that the liquid will be discharged from the reservoir through the orifice l3 in a short spurt, and on effecting a series of quick successive operations of the pump piston a like series of spurts of the liquid will be formed. Since the discharge of the liquid soap may thus be readily observed, the operator is able to determine the volume of the liquid soap delivered to a surface and accordingly may avoid excessive use or waste of the soap.
A dispenser embodying a hollow elongated member having a longitudinal wall and an end wall; a reciprocal piston extending through said end wall and into said longitudinal wall and formed with a port extending through a portion thereof housed in said longitudinal wall, said longitudinal wall being formed with a piston receiving bore longitudinally thereof and having an opening between the inner end of said bore and the hollow interior of the elongated member, also a discharge orifice across which said piston extends, spring means for normally holding said piston in a position with said port out of register with said orifice in the direction of the length of said piston, and a head on said piston arranged in outward spaced relation to said end wall adapted to be depressed to advance said piston longitudinally in opposition to said spring means to a position to register the port therein with the orifice in said longitudinal wall.
