1 Application July 29,1933, Serial No. 682,854

'Iihsinvention appertains to new and useful` is to provide a toothbrush wherein. theA head,-

tix of the brush is so constructed as to permit the bristle,` setstovv yield: toconform either with the outside of. the teeth.or;withv the inside.

Another` important object of the present invention is to provide a tooth brush which can be 10 used efficiently for brushing the front side as well as the inner side of the teeth without any manual manipulation to change the curvature of the bristle set contact area.

Another important object of the present invention is to provide a brush which will readily conform itself to the curvature of the surface against Which it is placed.

These and various other important objects and advantages of the invention will become ap parent to the reader of the following specification.

In the drawings: Y

Figure 1 represents a top plan view of the novel brush.

Figure 2 represents a side elevational view of the brush.

Figure 3 represents a side elevational View of the brush head, with the bristle sets curved for brushing the inside of teeth.

Figure 4 represents a side elevational view of the brush head, with the bristle sets disposed for cleaning the outside of teeth.

Figure 5 represents a cross sectional view taken substantially on line 5 5 of Figure 1.

Figure 6 represents a top plan View of one of the bristle set blocks.

Figure 7 represents a longitudinal sectional view through the head portion of the brush, with the bristle sets and blocks removed.

Figure 8 represents a sectional view taken substantially on line 8-8 of Figure 2, showing the bristle sets and blocks removed.

Figure 9 represents a longitudinal sectional View taken substantially on line 9--9 of Figure l.

Figure 10 represents an enlarged cross sectional View taken substantially on line` I0-I0 of Figure 7.

Figure ll represents a sectional View taken substantially on line II-I I of Figure 5, and 50 showing one form of bristle set.

Figure 12 represents a similar sectional view of a modiiication of the bristle set.

Figure 13 represents a similar sectional View to that of Figure 2, showing a slightly dilerent form of bristle set.

' on the outside of each of these members 'I and (Cl 154-167) f v l Referringy tos the drawingsgwherein like, num'.= erals. designate.v like. parts,y it.. can` beA seen. that. numeral.. V5. represents` the. tooth brnsh..handle;l while numeral 6 generally referate. thaabrllsh, head lwhich `includesa pair of. el'ongatedxnelallit:v members 'I-'I each provided withu an offsetend. portion. These offset, end. portions aredenoted by a and are brought together and suitably anchored in the head end portion of the handle 5. This leaves the outwardly projecting end portions of the members 'I-I slightly spaced apart, as is clearly shown in Figure 8.

Each of these members 1-1 is provided with a plurality of transversely extending slots 8 and l5 between the said slots are the rectangular bosslike guides 9.

As is clearly shown in Figures 11, l2 and 13, numeral ID represents the block of a bristle set I I and there are an equal number of bristle sets and blocks I0 to the number of slots 8 in each of the members 1 1. The blocks I0 are disposed along the outer sidesof the members 1-1 and as is clearly shown in Figure 5, pins I2- extend through the corresponding slots 8 in the members 'I 'I and each end of each of these pins extends into a corresponding block I0. Thus the blocks and sets are supported in pairs, a pair being located on each of the pins I2.

Located between the external extensions of the members "I I is the elongated hair spring I3 which has its hooked ends I4 hooked over the end pins I2. The major portion of this spring I3 isinterposed between the pins I2and` the pair of rivets I5-I5, which rivets are preferably located between the second and third sets, counting inwardly from each end of the head, as is clearly shown in Figure 9.

By referring to Figure 6, it can be seen that each of the blocks I0 is provided with notchedout portions I6-I6 which accommodate the guide bosses 9 so that the motion of the blocks will be transversely of the members '1 -1.

As can be clearly seen' in the drawings, the bristle sets will be normally retained in the position shown in Figure 9. When it is desired to brush the outside of the teeth, the bristle sets are pressed against the teeth and as the intermediate bristle sets are pressed against the teeth, their corresponding blocks I0 will be slid across the members 'I-'I and the action of their pins Y I2 against the hair spring I3 will cause the bristle sets at the ends of the head to move outwardly in the reverse direction so that the bristle sets will assume the formation shown in Figure 66 4. In this position, vwhich takes place automatically, the bristles are properly set so that all of the bristle sets will function usefully.

In cleaning the inside of the teeth, the end bristle sets will engage the teeth and will move their blocks l0 transversely across the members 1-1 so that their pins will press against the spring I3 and cause an inflex of thespring I3, which will force the intermediate bristle sets outwardly so as to afford a convex contact surface such as is shown in Figure 3, thus aording eicient use for all of the bristles of the brush.

In Figure 12, the bristle set and block`|0 is slightly modied by placing the pin l2 directly through the inner ends of therbristles, while in Figure 13, the pin I2 is xedrin the block I0 byv extending into the bristles slightly outward of the inner ends of thereof.

While the foregoing specification sets forth the' invention in specific terms, it is to be understood thatV numerous changes in the shape, size and materials may be resorted to without departing from the 4spirit andv scope of the invention as claimed hereinafter; i

:Having described: the invention,Y lwhat is claimedas new`is:-

` LA tooth brush comprising a handle, a head structure, said head structure being provided with a plurality of transversely extending slots, a plurality of bristle mounts, pins for slidably connecting the said bristle mounts to the head yat the said slots, and means between the said bristle mounts whereby pressure on the intermediate bristle mounts will cause the outermost bristle mounts to move outwardly, while pressure on the outermost bristle mounts will cause the intermediate bristle mounts to move outwardly.

2 A tooth brush comprising a handle, a head structure, said head structure being provided with a-plurality of transversely extending slots,
