- the left-end brush-headbase is free from bristles and may be used, alternately with that which has bristles, to carry an oifset brush-head of one of the various kinds referred to (or other kinds not here shown) for there are dental-conditions where the cooperation of two sets of bristles is desirable, and other dental conditions that call for use of a brush'pn. certain teeth or dentures that are adjacent to tenderor diseased gums to be untouched while brushing the teeth.
- the main purpose of offsetting the brush-heads is to gain free, easy and unobstructed brushing access to the posterior and lingual surfaces of the sets of teeth in theusers mouth.
- these offset brush-heads including bristles
- the handle is made relatively thin, wide and long to offset the turning tendency by a slight gripping pressure of the thumb and fingers of the users hand.
- This turning tendency is also offset, or overcome in part, by forming the shanks in a compound curve, aS'ShOWII, so the plane of the handle lies substantially in the same plane with the free ends of the bristles 4; the plane of the handle meaning the plane that lies in the length and breadth of the handle.
- this curving of the shanks provides easier working or brushing access of all-the bristles to the surfaces to be cleaned.
- the upper and lower sets of teeth are inwardly inclined towards one another, being relatively close together at points farthest posterior where the assembly 3c-5b-5b is narrowest when used in brushing these posterior teeth; but when thus used, the widest part of the assembly is in brushing contact with the more widely spaced teeth of the inclined sets.
- the unilateral assembly 'or arrangement is preferable to the bilateral arrangement; and in order that the operation of the unilateral assembly may be thoroughly understood, the handle-member may be consider'ed'as having two axes, viz., the longitudinal axis Iand'the transverse axis.
- the longitudinal axis is that about which the device is turned from the position shown in Fig. 1 to that shown in Fig. 2 without reversing the ends.
- the transverse axis is that which passes through or across the middle part of the handle, and about which the device is turned in reversing its ends. In brushing the outer surfaces of the upper set of teeth, the device as shown in Fig.
- the brush-head 5a at the right-hand end is used in the right side of the mouth and against the upper set of teeth and against the outer surfaces thereof; next, the device is turned about its transverse axis to bring the left-hand end into the left side of the mouth wherein the brush-head at the left engages with the outer surfaces of the upper set of teeth; then, to gain brushing access to the inner or lingual surfaces of the upper teeth, it is necessary to turn the device about its transverse axis to the reversed (end for end) position where the bristles project away from the user.
- the device may now be rotated on its longitudinal axis so as to turn the brush-heads 5a downward, and as the bristles will then extend towards the user, they arebrought into contact with the outer surfaces of the lower set of teeth by alternately turning the device about its transverse axis until the proper brushing contact is made with the right and left sides of said set of lower teeth; and finally, when it is desired to change the position of the device preparatory to brushing the lingualsurfa'ces of the lower teeth,
- the device is turnedabout its transverse axis to its reverse or end-for-end position where the bristles again point or extend outward, and the ends are respectively swung into the right and left sides of the mouth by swinging or turning the device about its transverse axis.
- Figs. 7, 8 and 10 the bristles are omitted, the bristle-sockets being shown at '6, but it-is understood that all the brush-heads are considered as including bristles. It is also intended that the outer edges of all brush-heads shall be of the semicylindrical or rounded form as shown in Figs. 3, '7, 8 and 10, so it will not only eliminate corners that might hurt the gums, but provides a hard smooth rounded surface for helping to massage the gums.
- Attaching studs. 1 fit into bores 8 and frictionally engage with the walls thereof in securing the brush-heads 5a and 5b in place, and studs Ta frictionally engage with the walls of the bores 8a for frictionally holding the brush-heads 5c, 5d and 5c in place; for as these studs are of springy material, it is only necessary to bend them slightly out of parallel with one another, so the parallel bores force them into parallel and combine therewith for effecting their frictional sliding engagement while permitting them to. be removed and interchanged. However, if desired, each engaging pin may be such 'as shown at lc (Fig. 9),
- split pins may be effected by bending halfround springy wire into the shape shown or into other appropriate shape.
- dovetail ribs Ir may be employed, and these may be split at Is longitudinally through a tapered part of the rib that normally fits in a tapered part of a groove 8g of the brush-headbase 3;. Both the ribs IT and walls of the grooves 8g are somewhat springy, so they effect the necessary frictional engagement for keeping the parts from becoming accidentally displaced while permitting them to be adjusted and interchanged by manually applied force. 7
- a tooth-brush comprising a handle member having one end formed with a relatively thin and long and wide brush-head-base, a relatively thin and wide and long brush-head provided with bristles and having one longitudinal thin edge normally fitted against a longitudinal edge of said brush-head-base and provided with means for removably securing it to the latter and for interchangeably securing it to the opposite longitudinal edge of the brush-head-base in a useful correlation with the latter.

'Fig. 10 is a transverse sectional view showing 1 9W any or. all forms of theinvention may have taken along the line the brush-heads arranged angularly, at different angles, with respect to the brush-head-base.
Referring to this drawing in detail, wherein, similar reference numerals refer to similar parts in the several views, the invention is described in detail as follows:
The main unit or handle member consists of the handle Ia or lb, shanks 2a or 2b or 20, and brush-head-bases 3, 3a, 3b, 30, 30H, 3) or 3g. The right-end brush-head-base tea may also be properly considered as a brush-head, being provided with bristles 4 as are the brush- heads 5a, 5b, 5c, 5d, 56, 5]", 5g and 5h. The left-end brush-headbase, however, is free from bristles and may be used, alternately with that which has bristles, to carry an oifset brush-head of one of the various kinds referred to (or other kinds not here shown) for there are dental-conditions where the cooperation of two sets of bristles is desirable, and other dental conditions that call for use of a brush'pn. certain teeth or dentures that are adjacent to tenderor diseased gums to be untouched while brushing the teeth.
' The main purpose of offsetting the brush-heads is to gain free, easy and unobstructed brushing access to the posterior and lingual surfaces of the sets of teeth in theusers mouth. When brushing teeth with these offset brush-heads (including bristles) ,there is a tendency for the handle to" turn in the hand of the user; so the handle is made relatively thin, wide and long to offset the turning tendency by a slight gripping pressure of the thumb and fingers of the users hand. This turning tendency is also offset, or overcome in part, by forming the shanks in a compound curve, aS'ShOWII, so the plane of the handle lies substantially in the same plane with the free ends of the bristles 4; the plane of the handle meaning the plane that lies in the length and breadth of the handle. Moreover, this curving of the shanks provides easier working or brushing access of all-the bristles to the surfaces to be cleaned.
Persons who consider theimportanoe of timesaving, and who wish to brush the upper and lower sets of teeth simultaneously, can accomp1 ish the same by employing the brush-heads in bi-lateral relation as indicated at the right end of Fig; 1 and at both ends of Fig. 4; and when thus used, advantages may be obtained by having'thebrush-headbases and brush-heads angular or'outw'ardly tapering as shownat 3b; 30, 5b and 5c, or by having only the one or the other (brush-head-base or brush-head) tapered, as is shown in Fig. -'6. When a 'persons mouth is open, the upper and lower sets of teeth are inwardly inclined towards one another, being relatively close together at points farthest posterior where the assembly 3c-5b-5b is narrowest when used in brushing these posterior teeth; but when thus used, the widest part of the assembly is in brushing contact with the more widely spaced teeth of the inclined sets.
For most thoroughly "cleaning the teeth and massaging the gingivae or gums, the unilateral assembly 'or arrangement is preferable to the bilateral arrangement; and in order that the operation of the unilateral assembly may be thoroughly understood, the handle-member may be consider'ed'as having two axes, viz., the longitudinal axis Iand'the transverse axis. The longitudinal axis is that about which the device is turned from the position shown in Fig. 1 to that shown in Fig. 2 without reversing the ends. The transverse axis is that which passes through or across the middle part of the handle, and about which the device is turned in reversing its ends. In brushing the outer surfaces of the upper set of teeth, the device as shown in Fig. 1 is held in the users hand, and the brush-head 5a at the right-hand end is used in the right side of the mouth and against the upper set of teeth and against the outer surfaces thereof; next, the device is turned about its transverse axis to bring the left-hand end into the left side of the mouth wherein the brush-head at the left engages with the outer surfaces of the upper set of teeth; then, to gain brushing access to the inner or lingual surfaces of the upper teeth, it is necessary to turn the device about its transverse axis to the reversed (end for end) position where the bristles project away from the user. Continuing the use of the device after brushing the upper teeth, it will be seen that the device may now be rotated on its longitudinal axis so as to turn the brush-heads 5a downward, and as the bristles will then extend towards the user, they arebrought into contact with the outer surfaces of the lower set of teeth by alternately turning the device about its transverse axis until the proper brushing contact is made with the right and left sides of said set of lower teeth; and finally, when it is desired to change the position of the device preparatory to brushing the lingualsurfa'ces of the lower teeth,
the device is turnedabout its transverse axis to its reverse or end-for-end position where the bristles again point or extend outward, and the ends are respectively swung into the right and left sides of the mouth by swinging or turning the device about its transverse axis.
It is a well recognized fact that tender gums need massaging for toughening them; but experience has proven that the sharp ends of bristles sometimes (if not quite often) scratch, puncture and irritate the gums so that they become sore and infected; so it is desirable to massage the gums or gingivae with the sides of the bristles while brushing the teeth and cleaning between the teeth with the ends of the bristles; and this dual operation can most satisfactorily be accomplished. by the angular relation of brush-headbase and brush-heads as shown in Fig. 10. Inasmuch as the setting of teeth differs in different persons mouths, it is desirable that different angularities be provided, and this may be accomplished by interchanging parts such as 59 and 5h in engagement with the brush-head-base 39.
In Figs. 7, 8 and 10, the bristles are omitted, the bristle-sockets being shown at '6, but it-is understood that all the brush-heads are considered as including bristles. It is also intended that the outer edges of all brush-heads shall be of the semicylindrical or rounded form as shown in Figs. 3, '7, 8 and 10, so it will not only eliminate corners that might hurt the gums, but provides a hard smooth rounded surface for helping to massage the gums.
Attaching studs. 1 fit into bores 8 and frictionally engage with the walls thereof in securing the brush- heads 5a and 5b in place, and studs Ta frictionally engage with the walls of the bores 8a for frictionally holding the brush- heads 5c, 5d and 5c in place; for as these studs are of springy material, it is only necessary to bend them slightly out of parallel with one another, so the parallel bores force them into parallel and combine therewith for effecting their frictional sliding engagement while permitting them to. be removed and interchanged. However, if desired, each engaging pin may be such 'as shown at lc (Fig. 9),
split approximately throughout its length and having slightly bowed springy sides that define the walls of the split 1d; and the formation of these split pins may be effected by bending halfround springy wire into the shape shown or into other appropriate shape. In lieu of the attaching studs, dovetail ribs Ir may be employed, and these may be split at Is longitudinally through a tapered part of the rib that normally fits in a tapered part of a groove 8g of the brush-headbase 3;. Both the ribs IT and walls of the grooves 8g are somewhat springy, so they effect the necessary frictional engagement for keeping the parts from becoming accidentally displaced while permitting them to be adjusted and interchanged by manually applied force. 7
Although I have described these embodiments of my invention specifically, it is not my intention to limit my patent protection to these specific details, for the invention is susceptible of numerous changes without departure from the inventive ideas as implied and claimed.
What I claim as my invention is: v
1. A tooth-brush comprising a handle member having one end formed with a relatively thin and long and wide brush-head-base, a relatively thin and wide and long brush-head provided with bristles and having one longitudinal thin edge normally fitted against a longitudinal edge of said brush-head-base and provided with means for removably securing it to the latter and for interchangeably securing it to the opposite longitudinal edge of the brush-head-base in a useful correlation with the latter.
2. A tooth-brush comprising a handle member having one end formed with a relatively thin and wide and long brush-head-base, a relatively thin and wide and long brush-head provided with bristles and having one longitudinal thin edge normally fitted against a longitudinal thin edge of said brush-head-base and provided with means for securing it in different adjusted positions along said brush-head-base.
