einen FREDERICK E. CLUM, OF DETROIT, MICHIGAN, ASSIGNOR F ONE-HLF TO JOSEPH W.

y DONALDSON, 0F DETROIT, MICHIGAN.

y TOOTHBRUSH AND PASTE HOLDER.

Application led November 8, 1920. Serial No. 422,447.

To all whom. it may concern- Be it known that I,` FREDERICK H. CLUM, Y a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Toothbrushes and Paste Holders. of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a combined tooth brush and paste holder or a tooth brush which is arranged to hold the paste and deliver it, as desired, to the brush, and its object is to provide a compact construction of lo neat appearance wherein the refilling of the device is greatly facilitated and a positive and accurate feeding of the paste to the brush secured without waste of material.

A further object is to providea tooth 2o brush of this character which is sanitary and in which the air is excluded from the tooth paste carried thereby at all'times except i when the brush is being used and in' which they-construction facilitates the cleaning of the device and lpermits of the detachment and replacement of the brush proper.

A further object of the invention is to provide certain other new and useful features, all as will hereinafter more fully ap- YV ith the above and other ends in View, the invention consists in providing a handle construction to receive a paste container and to provide a paste container with means forming a closure therefor for forcing the paste from the container. .The invention further consists in certain other matters 'hereinafter set forth and more` particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which Figure l is a longitudinal section through a device, illustrative of the invention;

Fig. 2 is a plan View of a portion of the same; v

Fig. 3 a detail showing an elevation of an end portion of the tubular handle;

Fig. 4 is a sectional detail of a cap for the end ofthe tubular handle; y

Fig. is an end elevation of Fig. 4.-;

Fig. 6 is a transverse section substantially upon the line VL-VI of Fig. l;

Fig. 7 is an elevation of a paste holder or tube detached and showing portions there of in section and broken away to more clearly disclose the construction; and

Fig. 8 is a side elevation of the device as shown in Fig. l, with the enclosingr cap or brush shield in place. As illustrative of an embodiment of the invent-ion, the device as shown in the drawings comprises a brush block l which is provided with the usual tufts of bristles 2 secured in the block in any suitable manner. To hold this block, a brush back 3 is provided having a shank portion 4 extending from one end thereof which shank terminates in a screwsthreaded nipple 5 to receive a tube or hollow handle 6 which is internally screw-threaded at one end to engage the nipple. rhe shank 4 of the brush holder or back is formed with a ledge l' adjacent the shank portion 4 to engage one end of the brush block l, and this shoulder is provided with an opening or short bore extending longitudinally of the shank to receive a pin 8 which is preferably integral with the brush block l. Adjacent the opposite or free end of the brush block, said block is provided with a hole extending therethrough to receive a discharge nipple 9 which is inserted into this hole between the tufts of bristles and is provided with a screw-threaded inner end to engage a screwthreaded opening in the brush back or holder 3. which holder is provided with a longitudinal channel l() communicating at one end withv the hollow nipple 9 and is extended through the shank portion 4; with its rear end opening into an internally screwthreaded socket l1 formed axially of the nipple 5 and arranged to receive the screwthreaded neck portion l2 of a paste tube or container 13 which is of a size to fit within the tubular casing or handle t3.

Then the paste tube is inserted in the handle 6 and screw-threaded into engagement with the socket 1l, paste may be forced therefrom by means hereinafter described, and this paste will pass through the channel l() in the brush holder into'the nipple 9 and thence out through the nipple and through a flexible extension l-l of the nipple, said extension being preferably a thiny rubber tube which is slipped over the end of the nipple and extends to near the ends of t-he bristles to deliver the paste to that portion of the bristles which come in contact with the teeth etY when the brush is used. The extension le being of th'in rubber will not interfere with the free. bending ot' the bristles and its" presence will not be apparent to the user of the brush while he is using it in brushing his teeth.

By means ot' the described construction, the brush block or member which carries the bristles may be readily detached trom the holder or back by simply inserting` a suitable instrument, indicated at l5, in dotted lines, into the end ot' the nipple S) Jfor turning the nipple to unserew it trom engagement with the holder. The removal otI this nipple permits the brush block to be moved endwise to disengage the stud or pin 8 from the opening into the holder`r and therefore` when the bristles become woi'ii this brush block may be readily detaehed and a new block with new bristles slipped into place. The block and nipple may also be readily detached for the purpose ot' cleaning out the channel.

through whieh the paste 4's delivered.

For convenience in handling. the tooth paste is put up in tubes b v tlu` manufacturer in the usual manner, the body and nipple end of these tubes being ot the usual construction` and when put up for shipment, the nipple being closed in the usual manner by a cap 16 (as shown in l"ig.' T). Insteadof the tube being closed atits opposite end by folding it into a seam as `is the usual'. ractiee. this end ot' the tube is closed hv a suitable disk or piston l? which lits closely Within the tube and has a cylindrical wall 18 of sull'ieientlcngtli to guide the piston iiiits movement in the tube. The wall ot' the tube., at its ext-renie end. is er'zmped or turned inwardly, as at 19. to engage the cylindrical wall of the piston and when the tube is lilled with paste b v the manufacturer. the piston is placed in the open end of the tube and then the wall of the tube crimped over to hold the piston in place. This piston. therefore` forms a closure for the end of the tube and every tube. when put out b v the manufacturer is provided with this end closure.

serew-threaded rod 2H extends through an axial screw-threaded opening in thepiston and through the paste contained in the tube to the opposite end thcicol". rlhis rod or stem has a torined head Q1 on its outer end by means of which the rod is turned and when. the tube is put upon the marketby the manufacturer oi the paste. it will eontaiu the rod and piston with the head 2l of the rod lying within the chamber formed in the end of the tube bv the c \liiidrical wall 1R of the pston. Therefore when the, paste tube is placed upon the market. the pistou and the sciew-threaded rod t'or moving the piston along the tube and forcing the paste therefrom. are in operative position with the head 2l which is provided for turning the rod, in a position to be engaged by a screwed on to the endl of the casing until the Y screw-three(led' portion 24 passes out of l engagement with the serei'v-threads an'ollie's within the reduced end portion2i`i`of'the'eas" ing. The' cap will th'enY turn treely'i'ipon the end ot' the'casiigwithoiit ji'no'ving end! wise and niaytherefore be turned toioperate the rod 2th the head A2li-rt' which is engaged with the socket 22 on' the cap when the cap is placed upon the end ofthe'easingv Vith the paste tube. in place within 'the easing and lend 'of' the easing withy the cap 23 upon the its socket 22 engaged with the end 2l v'of the ment t'orce tli'e piston or plunger 17 end'wie ofthe paste' tube and t'oicef thefpastetheree` troni out through the channel l() and nipple 9 to thc'biiish. A verv accurate feeding-of the paste is secured by this arrangement as none ot the'c `intents of the paste tube' can escape except through the dischargeehan-l nel and nipple and the piston prov'xdesa" positive means 'for forcing every particle of paste trom the tube. There isi therefore. no waste otilental lpaste either by ie'asonotany residue remaining'in the tubeor by reason of more paste being discharged than is nee.

essary. 'lhe construction also provides a very sanitary arrangement in that all parts are enclosed against dirt or dust getting into the channel or into the container for the tube and a new supply ot' paste may be quickly Aprovided bv simply unscrewing the casing G and 4removing the tube from which the paste has been used and screwing'a new paste tube into engagen'ient with the shank ot' the brush holder` the means for Jforcing the paste from the tube being in operative position within the new Vtube so that'by slipping tbe casing over the tube andengaging the cap therewith the-device Vis/again ready jfor use.

Y To proicct'the bristles of the brush nfrom injury and dirt and also to provide a tight closure tor the brushso thatthe. dental paste in the end vof the discharge nipple 9Will not harden thcreiiiand block up the passage, a tubular shield E27 Ais provided which "is iorincd with la' ti'i'bi'il'ar endfportion '28 4to lit closely over the end 'ottheshank 4 and adjacent end -oie -the easing 6, andthis' shield may be flattened or otherwise broadened fout screw stem 2l). -said Acap may' be yturned to to fit over and properly inclose the brush with its bristles.

Obviously, changes in the form, arrangement and combination of parts as shown in the drawing may be made within the scope of the appended claims, without departlng from the spirit of the invention, and. I do not therefore limit myself to the partlcular construction shown.

Havin thus fully described my invention, what I c aim is 1. In a device of the character described, the combination of a brush block, a holder having a seat to receive the brush block and formed with a longitudinal channel opening through said seat at one end, means for forcing dental paste into the opposite end of said channel, and means for detachably holding said brush block seated upon its seat.
