Application April 19, 1956, Serial No. 57,2l8 8 Claims. c1. 15-429 This invention relates to oral hygiene devices and particularly to a toothbrush and holder combination which selectively delivers water and an additive such as toothpaste, to the mouth of the user.

An object of the invention is to provide a practical toothbrush and holder combination which is capable of being produced by practical manufacturing methods in a small, lightweight condition, the device being arranged to deliver at the option of the user liquid under pressure through the head of the toothbrush or liquid mixed with an additive which may be selected by the user.

It is understood that tooth cleaning appliances of the fountain brush type have been constructed in the past. Accordingly, it is a further object of the invention to provide an improved fountain type toothbrush where the control for the passage of liquid through the toothbrush is most accessible to the user, it being located immediately below one or more of the fingers of the user when the device is held in the hand. Mere squeezing of the holder opens the normally closed valve to admit Water into the passage of the holder and passageway of the removably carried toothbrush in the holder.

A further objector the invention is to provide a combination toothbrush and holder wherein the toothbrush is easily separated from the holder and securely locked in the holder by a novel latch construction, the latter being openable by rotating a single lever several degrees and closed by rotating the same lever the same distance in the opposite direction.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a'part hereof, wherein like numerals refer to like parts throughout, and in which: 7

In Figure 1 there is a sink 10 mounted on wall 12, the sink having controls 14 and 16 which are used to select the temperature of water mixture which passes through the outlet pipe 16 and into the sink 10, This is but one type of many presently available arrarigemen'ts for water under pressure. Accordingly the with its controls and water outlet pipe 16 is intendedto be a schematic representation 'of any standard plumbing fixture capable of serving as a water supplyfor the water line 18. This water line has means at oneend for detachably connecting to'the water outlet pipe 16. For example the means may assume the form of a bell 20 of suitable, flexible material, for example rubber. The bell is frictionally fitted over the end of pipe 16 so that the water line 18 is supplied with water under pressure depending on the setting of thecontrols 14 or 16 As a companion to the water line 18 there is a conductor 22, the latter being secured to the line 18 for a considerable part of the length of the linefor convenience. It is preferred although notessential, that both line 18 and conductor 20 be madeof flexible tubing. The function of conductor 22 is tosupply an additive to the device 24 While the funetion ohli ne 18 is to supplywater under pressure thereinto. Therefore, a manually operable pump is in container 2 6 and is adapted to be operated by depression of handle 28. Container 26 has a supply of an additive for the liquid which passes through the teeth cleaning device 24. This additive may be liquid toothpaste, powder toothpaste or other liquid or powder such as a medication or cosmetic preparation. Mounting bracket 30 is on wall 12 and has means detachably securing the container 26 to it. I p

The teethcleaning device 24 consists of holder 32 and brush 34. I The brush is of approximately standard form having a handle 38 together with a head 40 at one end of it. The head has tufts ofbristles between which there are orifices 42 that are in registry with a water manifold 44 in the head of the brush. This manifold consists of the outer end of the liquid passageway 46 which extends completely through the longitudinal handle as and into the head 40 of the brush. The outer end of handle 38' is preferably smoothly curved as at 47 (Figure 5) in order to seat Well on the yielding seat 48 that is located in holder 32.

Holder 32 comprises a body 50- that has a sleeve 52 protruding therefrom and fitting around a part of body 50. The U-shaped end 54 of sleeve 52 is juiitaposed over three sidesof the body 50. Cover 56 is disposed over portions of two of the sides ofthe body 50' and the fourth side thereof. The cover 56 is shaped to fit neatly in the hand of the user and has a pair of bolts 58 Which holds it fastened to body 50. Handle 38 of the toothbrush is located in bore of sleeve 52, the dimensioning of the handle and the bore being such thatthe handle fits snugly therein. When pressed gently into the bore of sleeve 52 the curved end 47 of the handle 38 presses on the flexible, for example rubber, seat 48, Seat 48 has an aperture in it which is inregistry with the passageway 46. A longitudinal passage 60 is formed in body 50 and is in communication with the aperture of a small plate 66 and having an angulated end wall 67, is adapted to be pressed into the notch 62 in order to hold the toothbrush firmly in place. When in the latched condition the angulated'walls 64 and 67 are nested with each other (Figure 2). A lever 68 is pivoted on a pin 70 to the exterior of sleeve 52 near the opening 72 therein. This pin is mounted in ears that are carried by the sleeve 52, whereby the lever 68 is capable of swinging movement toward and away from the holder 32. A link, for example a U-shaped lightweight, wire 74 is pivoted at one end to the lever 68 and pivoted at the opposite ends to the keeper 66. When the lever 68 is swung outwardly to the position shown in Figure 4 the keeper plate 66 slides outwardly from beneath a part of sleeve 52 and from within the notch 62. When the lever 68 is swung in the opposite direction the keeper plate 66 is swung inwardly and downwardly fitting in the small pocket (Figure 2) 75 which is formed by wall 64 of notch 62, a part of the innermost wall of notch 62 and the inner surface of a part of the sleeve 52.

A valve 78 is carried by the holder 32 and constitutes a part thereof. The valve consists of a stem 79 having a threaded end 80 on which the valve element 82 is threaded. Stem 79 is operable in a bore 83 which is arranged generally parallel to the passage 60. Spring 84 holds the valve 78 in the normally closed position and is disposed in a counterbore 85, the counterbore being-in alignment with bore 83. This spring seats upon the end of counterbore 85 and on a sliding block 86 to which the outer end of stem 79 is secured. A pilot rod 88.is fixed to an offset part of the sliding block 86 and is operable in a passage 87 parallel to bore 83. Ali?! ture 90 is formed in sliding block 86 in order to connect links 91 and 92 thereto by means of a pivot pin. The outer ends of links 91 and 92 are pivoted to link 93, the latter being mounted for pivotal movement on pin 94 that is carried by brackets on the outer surface of sleeve 52 near the opening 72 in this sleeve.

A valve chamber 96 is formed in the body 50 and ha the valve 78 operable therein. This valve chamber has a valve seat 97 in it between its ends, one end of the valve chamber being in registry with the passage 60 so that the valve 78 controls the flow through passage 68. Coupling 98 is threaded on a part of the body 50 at valve chamber 98, this coupling having water line 18 attached to it for operative connection with holder 32.

The conductor 22 has an end fitted over the nipple 100, the latter being part of a right angular coupling 102 in which there is a normally closed check valve 104. This right angle connector is threaded in the body 59 and has its passage in registry with the lower end of passage 60.

In use the device is held in the hand with holder 32 arranged such that the link 93 is beneath at least one of the users fingers. With the other hand the user depresses pump actuator knob 28 so that a charge of liquid or powder passes through the conductor 22, check valve 104 and into passage 60 where it is mixed with the Water flowing into the head of the toothbrush. After experiencing the device the prerogative of the user will be exercised in how to administer oral hygienic treatment to himself. Inherent in the described embodiment of the invention is suflicient versatility for performing a number of approved functions in oral and dental hygience.

In order to remove the toothbrush for one reason or another, the actuation of lever 68 from the position shown in Figure 2 to the position shown in Figure 4 is all that is necessary. Then the toothbrush is capable principles of the invention.
