Application filed. September 27, 1915. Serial No. 52,888.
To all whom it may concern.-
Be it known that I, Jose: ARBAT, a subject of the King of Spain, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Tool for Cleaning Teeth, of which the following is a full, clear, and exact description.
Among the principal objects which the present invention has in view are: to provide a handle and a series of brushes employed in conjunction therewith adapted for special use in the operation of cleaning teeth; to provide protective means constructed from vitreous material; and to provide means for condensing the occupied space of a tool of the character described,
Drawings.'Figure 1 isa side view of a tool and brush operatively' connected therewith, constructed and arranged in accordance with the present invention, the handle of the tool being shown in section; Fig. 2 is a cross section taken as on the line 2 2 in Fig. 1; Figs. 3 and 4 are side views of modified forms of brushes to be used in conjunction with the handle and guard plate herein described; Fig. 5 is a view showing the parts of a brush as separated and disposed in a carrier; Fig. 6 is a detail view on an enlarged scale, showing an end fragment of one of the brushes and afragment of the guard plate supporting the outer end thereof. j
Descriptiom-As seen in the drawings, the
handle of the tool herein described, consists primarily of a hollow tube 10. The tube 10 is closed at the forward end to form a hearing for the journal llformed at the'end of a rotary shaft 12. Atopposite ends of the bearing 11, thrust collars 13 and 14 are provided to maintain the relative disposition of the shaft 12 in the tube 10. i
The shaft 12 .is furnished with a'spiral groove 15, wherein is moved a driving pin 16 formed at the end ofia hollow plunger 17. The plunger 17 is held non-rotatably in relation to the'tube 10 by a feather 18 formed on the side of said plunger to move in a slot formed in the head 19 on the tube 10.
The oflice of the plunger 17 is primarily to produce a rotation in the shaft 12, and to this end, the plunger is thrust into the tube 10, a thumb pad 20 being provlded to facilitate this action. To produce the counteraction, or to thrust the plunger 17 from the tube 10, a spiral sprmg 21 is installed within the tube 10. This spring normally expands to move the plunger 17 to the outer position thereof, as seen best in Fig. 1 of the drawings When 1t is desired to pack the tool, the plunger 17 1s forced within the tube 10 until the feather 18 clears the head 19, and until the screw-threaded section .22 of the plunger 17 registers with threads formed on the edge of the opening in the head 19. By turning the plunger 17 when in this position, the .threads of the section 22 engage the threads of the head 19 and hold the plunger thereafter within the tube 10, the spring 21 being compressed.
To operate the plunger 17, the thumb of the person using the tool is placed on the pad 20. The first and second fingers of-the hand of the user are then extended through the loops or rings 23, which loops or rings are r gidly mounted on and laterally extended from the tube 10. When the plunger 17 1s forcefully inserted through the tube 10, the pin 16 passing through the groove 15, produces a rapid'rotation of the shaft 12 and of the brush 24, 25 or 26, which maybe engaged by the chuck socket 27 formed on the j shaft 12 and at the outer or forward end of the journal 11 thereof. The chuck socket 27 and one end of each of the spindles 28, with which saidbrushes are provided, are correspondingly squared or formed rectangular in cross sectlon. The opposite ends of .said spindles are rounded to-form pivot ends 29.
The pivotends 29 each rest, when in service,
in a rounded socket formed in the end of a spring-seated plunger 50. The plunger 30 is normally forced outwardly from the end .of a cup socket 31, by a spring 32, which is housed in the said cup socket, as shown best in Fig. 6 of the drawin s.
the tube 10 and the guard plate 33 is such as to permit, rapid and ready separation of the plate from the tube. While it is specified that the material from which the guard plate is constructed is preferably of the character mentioned; it will be understood that any suitable material, such as silver,
spindle 28 on the selected brush is introduced into the socket of the plunger 30. The
[plunger 30 is then pressedback, compressing the spring 32, until the squared end of the spindle 28 is oppositethe squared chuck socket 27. The spring 32 is now permittedto move the brush to'set the squared end of the spindle 28 operatively in the said chuck socket. The brush is now installed for. use. The user now places his fingers within the i rings 23, his thumb resting on the pad 20.
After the tool has been properly introduced into the mouth so that the brush is in ',contact with or juxtaposed to the teeth, the user depresses or forces the plunger 17 within the tube 10 and compresses thespring 21, which, in turn, extends the plunger when pressure of the thumb thereon is relieved.
- A number of ra id movements of the plunger 17 produces 1n the shaft 12 and the brush operatively connected therewith, a corresponding rotation. The brush being now pressed against the teeth, cleanses the same, the bristles of the brush extending naturally between the teeth and preferably stroking the same from the gum toward the crown of the teeth.
The brush 24 is generally used for cleaning the outer side of the teeth. After this has been accomplished, the brush 24 is removed by forcing backward the plunger 30 until the squared end of the spindle 28 is removed from the chuck socket 27. The brush 25 is then installed in place of the brush 24:. The shape of the brush 25 lends itself more readily to the operation of cleansing the inner side of the teeth. To clean the inner side of the front teeth, the brush 26 is especially designed. The brush 25 may be removed and the brush 26 easily installed in the same manner as described with reference to the brushes 24 and 25.
After the operation of cleaning the teeth, the tool and brushes are separated for packing. To this end, the plunger 17 is forced within the tube 10 until the threaded section 22 thereof may be screwed into the threaded opening of the head 19. The guard plate 33 is then removed from the tube 10, being unscrewed from the end thereof. As shown in Fig. 5 of the drawings, a box-like .receptacle is provided wherein the various parts of the tool and the brushes used in conjunction therewith are disposed within a condensed area. It will beseen that a convenient package is thus formed, which may be placed in the pocket of the user, or in a traveling satchel without inconveniencing the traveler. I
A tool as characterized, comprising a tubular handle, a spirally grooved shaft rotatably mounted in said handlea reciproeating plunger telescopically and non-rotatably mounted within said handle; means provided on said plunger for extending within the groove in said shaft for rotating said shaft when said plunger is reciproeated; manually operated means for moving said plunger in said handle; and means for locking said plunger and said handle in telescoped relation, said means embodying male and female screw-threaded sections on said plunger and said handle, respectively.
