1937. J. J. PETTA 2,091,716
TOOTH BRUSH Filed April 1, 1936 Patented Aug. 31, 1937 UNITED STATES PATENT orrica TOOTH BRUSH John J. Petta, Chicago, Ill. Application April 1, 1936, Serial No. 72,091
3 Claims.
This invention relates to improvements in tooth brushes and has special reference to a construction which will permit the positioning of the handle of the brush in different relations to the brush proper.
The object of the invention is to provide a tooth brush so constructed that the brush can be readily arranged to present the bristles of the brush normally to the interior surfaces of the teeth, that is with the bristles projecting toward the handle, or it can be arranged similarly to the usual form of tooth brush with the bristles projecting out from one side of the handle.
The invention comprises a brush head and a 5 handle, and the two so connected and mutually cooperative that the brush can be readily arranged in a position when the head is in effect an extension of the handle and the bristles project from one side, or the head can be arranged across the handle with the bristles projecting toward the handle, and means for latching or looking the two parts in either relative position as desired.
The invention will be more readily understood by reference to the accompanying drawing forming part of this specification and in which:--
Fig. l is a face view of a tooth brush embodying the invention;
Fig. 2, a side view thereof;
Fig. 3, an enlarged sectional view taken on the line 3-3 of Fig. l; and
Fig. 4 is an enlarged the line 4-4 of Fig. 1.
As shown in the drawing, my improved tooth brush comprises a head or bristle carrying memher l0 and a handle member II.
The head I0 is pivotally mounted on one end of the handle member to swing from one relative position as shown in Fig. 1, when the brush simulates an ordinary tooth brush, to a second position, as shown in Fig. 3, when the head It! is arranged extending across the handle with the bristles l2 projecting toward the handle H.
The handle is preferably made of a small tube l3, at the end carrying the head l0, and the outer end of the tube [3 is secured in an outer handle part I4 which is shaped approximately like the usual tooth brush handle, that is relatively Wide and flat.
The handle part I4 is hollow, that is, it is provided with a longitudinal hole M in line with the tube 13, and a control rod l5 extends through the handle II, that is, through the part I4 and I the tube 13, and projects from the handle at each end.
The handle sectional view taken on l l is pivotally mounted at its inner end to the head It) at a point substantially mid- Way between the ends of the head on a pivot pin I6 which extends transversely through the head. The inner end of the tubular part l3 of the handle is enlarged on its side toward the brush head as shown at IT, so that it can be provided with an opening to receive the pivot pin I6 without interfering with the rod I5.
The head H3 is provided with a longitudinal groove is extending from one end to the midpoint to receive the tube i3 when the head is arranged extending longitudinally of the handle l I.
The inner end I!) of the rod l5 projects from the inner end of the tube it past the pivotal point and the head is provided with two holes 20 and 2| receiving this projecting end and locking the head in its two positions.
The hole 28 extends in line with the rod l5 when the head extends longitudinally of the handle and the hole 2! extends in line with the rod 15 when the head is swung to its other position, that is to a position at right angles to the handle.
The rod I5 is yieldingly held at the inner limit of its movement in the handle by a spring 22 within the hollow handle. The rod is provided with a rigid shoulder 23 against which the inner end of the spring presses and the outer end of the central opening in the handle is closed by a plug 24 against which the outer end of the spring presses.
The outer end of the rod I5 is provided with an enlargement 25 so that it can be grasped and pulled out to free the head Ill from the inner end of the rod and permit the head to be swung from one position to the other.
The construction is very simple, cheap and strong and the head can readily be arranged with the bristles projecting toward the handle for operation upon the inner surfaces of the teeth, especially the front teeth, and can as readily be arranged to project the bristles from one side, like an ordinary tooth brush, and the head is held firmly in both positions.
As many modifications of the invention will readily suggest themselves to one skilled in the art, I do not limit or confine the invention to the specific details of construction except within the scope of the appended claims.
I claim:
1. A brush comprising a brush head having bristles projecting from one face thereof, said face being provided with a central groove extending from one end to the center thereof; a handle pivotally mounted at the center of said notches in said head to receive the protruding end of said rod to lock said handle in either of its adjusted positions.
3. In a tooth brush, a brush head having bristles projecting from one face thereof, a handie pivotally mounted substantially at the center of said face and movable to project longitudinally of the head or at a right angle to the head from said face and spring pressed releasable means for locking the handle in either of its two positions. 10
