J. M. CALKINS TOOTHBRUSH Filed Nov. 26, 1926 INVENTOR J M CAL/0M9 E BY 2 ATTORNEYS Patented Nov. .29, 1927.
UNITED STATES JAMES MURPHY CALKINS. 013 DETROIT, MICHIGAN.
TOOTHBRUSH.
Application filed November 25, 1926. Serial No. 150,847.
My invention relates to improvements in tooth brushes, and it consists in the combinations, constructions. and arrangements herein described and claimed.
An object of my invention is to provide an an improvement over my Patent No. 1,600.- 975, issued September 28. 1926. The improvement consists in providing a device which is simpler in construction. which is 10 more easily operated, and which maybe used c more efficiently.
The only manner in which teeth may be thoroughly cleaned is by movingthe brush back and forth from the gum to the end of the teeth and positioning the head of the brush in substantial alignment with the row of teeth being cleaned. positioning the head of the brush in this manner, the bristles may readily extend between the teeth, and by movement of the bristles, all the substance lodged between the teeth may be readily .removed therefrom. This cannot be performed by the ordinary type of tooth brush, and it is an object of applicants invention to provide a device by means of which this may be accomplished.
A further object of my invention is to provide a device of the type described in which the handle may be adjusted to various positions so that the head may he moved so as to clean the teeth properly.
A further object of my invention is to provide a device of the type described n which the handle may be moved to any desired position and firmly held in this position without removing the head of the brush from the mouth.
A further object of my invention is to provide a device of the type described in which a head of special construction is provided for cleaning the out-er surfaces of the teeth, and a head of special. construction is provided for cleaning the inner surfaces of the teeth. a v .A further object of my invention is to provide a device of the type described in which the handle may be readily removed from one of the brush heads and readily inserted in the other.
A further object of my invention is to provide a device of the type described in which the handle is firmly held in the head of the brush during its movementinto the various positions.
Otlf objects and advantages will appear in. the flowing specification, and the novel features of the invention will be particularly pointed out. in the appended claims.
My invention is illustrated in the accompanying drawings, forming part of this application, in which i Figure 1 is a plan view of the device, a portion thereof being broken away,
Figure 2 is a section along the line 2-2 of Figure 1,
Figure 3 is an enlarged bottom plan view of one end of the handle.
Figure lis a brush head for cleaning the outer surfaces of the teeth, and
Figure is abrush head for cleaningthe inner surfaces of the teeth.
In carrying out my invention, I provide two brush heads indicated generally at A and B, both having backs 1 and 2 which are identical in construction. These backs are provided with substantially rectangularshapod recesses 3 and 3. The backs are provided with enlarged portions 4 and 4 beneath the recesses 3 and 3 and enlarged portions 5 and 5 above the recesses 3 and 3. The backs 1 and 2 are provided with pivot pins 6 and 6 which are positioned substantially at the center of the heads within the recesses 3 and 3'.
The outer surfaces of the enlarged portions 1 and 1 and 5 and 5 are substantially arcuate-shaped forming their arcs from the centers of the pivot pins 6 and 6. These surfaces are formed of substantially flat engaging surfaces 7, 7, 8, 8, 9, 9, 10, 10, 11 and 11.
The enlarged portions 4 and 4: are provided with openings 12 and 12. Resilient strips 13 and 13 are rigidly secured at one end to the lower extremities of the pivot pins 6 and (3', and extend outwardly perpendicular to the rear surfaces oi? the recesses 3 and 3. Retaining lugs 14 and 1 1 are disposed in the openings 12 and 12 and'are rigidly secured at their lower ends toithe resilient strips 13 and 13. The retaining lugs 1i and 14 have rounded upper ends 15 and 15 for a purpose hereinafter described.
The head A is provided with two sets oi bristles 16, the free ends of which provide a substantially concave surface 17. A recess 16 isprovided between the sets of bristles 1G, The head B is provided. with two sets of bristles 18, the free ends of which form a substantially convex; siiiiiti e 19 A 18 providedhetwsen the. sets said recess, said handle adapted to be moved with respect to said back for bringing said shoulder into engagement With any of said engaging surfaces, and means for locking said extension in said recess, whereby said shoulder is firmly held adjacent one of said engaging surfaces.
2. A tooth brush comprising a back having a recess therein, a pin disposed through said back and said recess, a handle, a tongue integral with said handle and having an arcuate-shaped recess in the outer end thereof for receiving said pin, said handle and said tongue adapted to be swung about said pin, and means for engaging with said tongue for removably securing said tongue and said handle in any desired position With respect to said back.
3. A tooth brush comprising a back having a recess and an opening therein, a pin disposed through said back and said recess, a resilient strip rigidly secured at one end to said pin, a lug rigidly mounted upon said strip and extending through said opening, the free end of said lug extending into said recess, a handle, and a tongue integral with said handle and having an arcuate-shaped recess in the end thereof, said tongue having an arcuate-shaped groove and openings equally spaced Within said groove, the recess in said back being adapted to receive said tongue when said strip and said lug are moved outwardly, the arcuate-shaped recess in said tongue being adapted to receive said pin, and said lug being receivable in any one of the openings in said tongue.
