FOUNTAIN COMB Filed June 1, 1938 A iiorneys Patented July 4, 1939 UNITED STATES PATENT ori 2 Claims.

This invention relates to a fountain comb, the general object of the invention being to provide the comb with a reservoir at its upper portion for receiving various kinds of solutions for the treat- 5 ment of the scalp, with manually controlled means for causing some of the solution to pass from the reservoir to the tooth carrying edge of the comb.

This invention also consists in certain other features of construction and in the combination 1,0 and arrangement of the several parts to be here- "2 ure 1.

Figure 3 is an enlarged fragmentary vertical sectional view showing the valve means.

In this drawing the letter A indicates the comb and the letter B indicates thereservoir the lower 5 edge of which is connected with. the upper edge of the comb in any suitable manner. One end portion of the reservoir is made of greater height than the rest of the reservoir and this high part is formed with the two spaced upwardly extend- 30 ing parts preferably shaped as shown, these parts forming a recess 2, the bottom of which is formed with an opening 3 closed by a cork 4 which is cemented in place. Below the recess the comb is formed with an opening 5 in which is 35 cemented a cork 6 which has a longitudinally extending hole or bore 1 therein which leads from the reservoir through the lower edge of the body of the comb.

A plate 8 extends across the bottom of the recess 40 2 and across the top of the cork 4. A valve rod 9 passes through a hole in the plate 8 and through a hole in the cork 4 and said rod also passes through the bore 1 of the cork 6 and has a valve 7 disk ill at its lower end for closing the lower end 45 "of the bore 1. The upper end of the rod extends above the plate 8 but terminates short of the plane of the top part of the portions I so that these parts I prevent the valve rod being depressed to open the valve Ill by accident, such as 50 the upper part of the reservoir being struck by an object or pressed against an object. A button II is connected with the upper end of the valve rod for facilitating the depression of the rod and a spring l2 encircles the upper portion of the rod 55 and has one end bearing against the button H and the other against the plate 8. A small cylinder I3 is located in the space between the two corks and the valve rod passesthrough the cylinder. The valve rod carries a piston it of leather orthe like which operates in the cylinder r and the upper open end of the cylinder is formed with the notches l5 and its lower end is outwardly bowed as shown at lfiand provided with a central port l6 through which the valve rod ii extends, said port 16' being slightly larger than the rod 9 for a purpose presently seen. This ported end it: is spaced from the cork 5 when the upper end of the piston is engaging the cork sand in axial alignment with the bore 1; I A filling opening is formed in a part of theZi-lfi reservoir and is closed by a plug ll" 50 that by removing the plug, tonic or other solutions can be placed in the reservoir and then the plug is closed. Then when it is desired to place some of the solution on the scalp theu'ser presses'uponifli the button ll tolower thevalve rcd'i which 20 opens the valve I9 and on the first part of the downward movement of the stem the frictional engagement of the piston M with the cylinder 13 will cause'the cylinder to move clownwardlyf -iuntil its lower ported end I6 rests upon the cork 6 with the port- It registering with the bore 1. Then further'downward movement of the valve rod will cause the piston M to eject some of the solution in the cylinder through the port I and past the valve I0 upon the scalp or other part of the body over which the comb is being drawn. Then when the button is released the spring l2 returns the parts to the normal position and on the first part of this upward movement of the valve rod the cylinder It will move upwardly with the piston l4 until its notched end strikes the cork 4 when further movement of the cylinder will be prevented and then as the valve rod continues its upward movement the piston M will draw some of the solution into the bottom of the cylinder through the port I6. Of course, the notches I5 prevent air being trapped in the top of the cylinder by the piston.

The teeth of the comb at the point where the opening 5 is formed are spaced a greater distance apart than are the other teeth and these two teeth are made larger as shown at 58 to protect the smaller teeth when the device is being used to apply solution to the scalp or other part of the body.

While I prefer to use corks 4 and 6 for closing the upper and lower openings it will, of course, be understood that any other suitable material can be used for these members and such mem- 56 bers can be of resilient material so that the valve plate l will make a fluid tight joint with the lower end of the member 6 and the stem will have a sliding fluid tight passage through the upper member 4. The plate 8, of course, prevents the spring from embedding itself into the top part of the member 4.

As will now be seen, I have provided a fluid measuring cylinder 13 endwise movable in the reservoir B in opposite directions, respectively, under similar movement of the valve rod 9 and between opposite limits of movement established by engagement thereof with the corks 4 and 6, the

ported end l6 of the cylinder being opposed to the bore 1 in one limit of movement of said cylinder so as to block communication between said bore and the reservoir B and so as to provide for ejection of the measured amount of fluid from the cylinder through said bore under the action of the piston l4, the ported end [6 of said cylinder being spaced from said bore I in the other limit of movement of the cylinder for the filling ofthe cylinder through the port 16' with a uniform amount of fluid each time the valve rod 9 and piston 14 are operated by the spring l2.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A fountain comb comprising a back having a toothed edge and a discharge duct extending therethrough for conveying liquid to said edge, a liquid-containing reservoir on said back with which said duct communicates, and means to eject a measured amount of liquid out of said duct comprising a liquid-measuring cylinder endwise movable in the reservoir between opposite limits of movement and having a ported end opposed to said duct in one limit of movement of said cylinder to block communication between said duct and reservoir and provide for ejection of fluid into the duct directly from said cylinder,

said ported end in the opposite limit of movement of the cylinder being spaced from said duct for the filling of the cylinder therethrough from the reservoir, and a plunger extending into said reservoir and cylinder, said plunger being manipulative inwardly of the cylinder to move the same into the first-mentioned limit of movement thereof and subsequently eject the fluid therefrom through said ported end and into said duct, and being tensioned for movement outwardly of said cylinder to move the latter into said opposite limit of movement thereof and subsequently draw fluid from the reservoir into the cylinder by way of the ported end of the latter.

- 2. A fountain comb comprising a back having a toothed edge and a discharge duct extending therethrough for conveying liquid to said edge, a liquid-containingv reservoir on said back with which said duct communicates, and means to eject a measured amount of liquid out of said duct comprising a liquid-measuring cylinder endwise movable in the reservoir between opposite limits of movement and having a ported end opposed to said duct in one limit of movement of said cylinder to block communication between said duct and reservoir and provide for ejection of fluid into the duct directly from said cylinder, said ported end in the opposite limit of movement of the cylinder being spaced from said duct for the filling of the cylinder therethrough from the reservoir, and a plunger extending into said reservoir and cylinder, saidrplunger being manipulafluid from the reservoir into the cylinder by way of the ported end of the latter, said plunger ex--' tending through said duct and having an enlarged end coacting with said back to establish an outward limit of movement of the plunger and simultaneously close the outer end of the duct to prevent leakage of the fluid therefrom.
