Application July 15, 1955, Serial No. 522,193

2 Claims. (Cl. -133) This invention relates to tooth brushes, and more particularly to an improved tooth brush of the fountain type especially adapted for use by children.

A main object of the invention is to provide a novel and improved fountain tooth brush which is simple in construction, which is easy to operate, and which is attractive in appearance, whereby the tooth brush appeals to children and stimulates children to form the habit of daily tooth care.

A further object of the invention is to provide an improved fountain tooth brush which is inexpensive to manufacture, which is durable in construction, and which is of special interest to children, creating the desire to employ the tooth brush because of its resemblance to a toy water pistol.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawing, wherein:

Figure 1 is a side elevational view, partly broken away, of an improved fountain tooth brush constructed in accordance with the present invention.

Figure 2 is a fragmentary plan view of the forward portion of the tooth brush of Figure 1, said plan view being taken on line 22 of Figure 1.

Figure 3 is an enlarged vertical cross sectional view taken on line 3-3 of Figure 2.

Figure 4 is an elevational view of a holster which may be employed as the supporting bracket for the tooth brush of Figures 1 to 3.

Referring to the drawing, the improved fountain tooth brush is designated generally at 11 and comprises an elongated barrel member 12 having a reduced forward end portion 13, said forward end portion being further reduced at 15, defining a tooth brush back. Designated at 16 are a pair of rows of tooth brush bristle tufts secured in parallel relationship to the reduced portion 15,"

defining a tooth brush head.

The reduced portion 15 is formed with a plurality of longitudinally spaced apertures 17 located midway between the rows of bristle tufts 16, as shown in Figure 3, for example, three apertures 17 being provided, said apertures being spaced uniformly along the tooth brush back element 15.

The barrel 12 is formed with a hollow depending handle member 18 in which is rigidly secured the horizontally extending cylinder 19. A piston 20 is slidably mounted in the cylinder 19 and is urged forwardly by a coil spring 21 in the cylinder bearing between the piston 20 and the rear end wall of the cylinder, as shown in dotted view in Figure 1. Axially secured to the piston 20 is a piston rod 22 which extends sealingly and slidably through the front wall of the handle 18 and which is provided on its forward end with a trigger-like, arcuately curved bar element 23, said bar element being located within a trigger guard loop 24 connecting the bottom surface of the barrel member 12 to the front edge surface of the handle 18.

ice

The cylinder 19 is formed at its rear portion with 21 depending conduit element 25 which terminates at a point adjacent to but spaced from the bottom of the handle 18. Connected to the top of the cylinder 19 in alignment with the conduit 25 is a conduit 26 which extends longitudinally through the barrel 12 and which communicates with a bore 27 formed in the forward end portion of the barrel and which in turn communicates with the apertures 17. Suitable check valves are provided at the connections of

conduit elements

25 and 26 to cylinder 19, said check valves being shown in dotted view above and below the rear portion of the cylinder in Figure 1.

The rear end of the barrel 12 is hollow and is provided with a removable plug or cap 28 which may be removed when it is desired to fill the handle 18 with liquid, such as with water.

In using the device, the person employing same grasps the handle in the manner of a conventional water pistol and, after applying suitable tooth cleaning material to the bristles 16, reciprocates the bristles over the teeth while at the same time squeezing the trigger bar element 23 to provide a flow of water to the bristles simul taneously with the application of the tooth cleaning ma terial to the teeth.

It will be readily apparent that the appearance of the device is such as to create suitable interest in children and to stimulate children to use the device, thus creating the habit of daily tooth care.

Referring to Figure 4, 30 designates a bracket member in the form of a holster adapted to receive the device 11, the holster having the rear wall 31 provided at its top portion with the eyelet 32, whereby the holster may he hung in a suitable location to support the fountain tooth brush device 11.

As shown in Figure 4, the holster 30 comprises a transversely extending, relatively wide supporting strap element 33 which is secured at its side margins to the downwardly tapering side marginal portions of the main body 31 of the holster, defining a receptacle to receive the fountain tooth brush device 11.

While a specific embodiment of an improved fountain tooth brush has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.

What is claimed is:

1. A fountain tooth brush comprising an elongated horizontal barrel member, a plurality of tooth brush bristle tufts secured to and projecting laterally from one side of one end of said barrel member, a depending hollow handle secured to the other end of said barrel member, a cylinder mounted horizontally in said handle member and communicating at one end thereof with the interior of said handle member, first check valve means in the connection between said one end of the cylinder and the interior of the handle member, a piston in said cylinder, a piston rod connected to said piston and extending sealingly through the forward edge of said handle member, said one side of the one end of the barrel member being formed with a plurality of spaced apertures located adjacent said bristle tufts, conduit means in the barrel member connecting said apertures with said one end of the cylinder, and second check valve means at the connection of said conduit means to said one end of the cylinder.

2. A fountain tooth brush comprising an elongated horizontal barrel member, a plurality of tooth brush bristle tufts secured to and projecting laterally from one side of one end of said barrel member, a depending hollow handle secured to the other end of said barrel member, a cylinder mounted horizontally in said hollow handle, a depending tube connected to one end of said cylinder and terminating adjacent the bottom of said hollow handle, a first check'valve in the connection of said tube to said one end of the cylinder, a piston in said cylinder, a piston rod connected to said piston and extending sealingly through the forward edge of said handle, a trigger-like bar element secured on the outer end of said piston rod, said one side of the one end of the barrel member being formed with a plurality of longitudinally spaced apertures located adjacent said bristle tufts, conduit means in the barrel member connecting said apertures "with said one end of the cylinder, and a second check valve in the connection between said conduit means and said one' end of the cylinder.
