My'present invention relates to an improved tooth paste dispenser which while adapted especially Vfor use in dispensing 4dental paste is capable of being usedfor l dispensing numerous other similar materials, as soap in aste form. The invention con templates t e use of a stationary, sanitary device of this character whereby a supply of' the paste may with facility be discharged from a collapsible tube, and the supply automatically cut 0E after the proper quantity has been supplied, for the purpose of preventing waste. I
The dispensing device which involves a l'l minimum number of parts in compactly arranged and is simple in construction and operation, reliable, durable and not likely to become deranged from use.
Means are provided whereby the collapsible tube may be shortened to compensate yfor the absence of material as the latter is discharged, and means are also provided whereby vthe used. tube, after its contents have been exhausted, -may readily be re- 25 moved from the device and replaced by a full tube.
The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. In the accompanying drawin s I have illustrated one complete example o the hysical embodiment of my invention where-l in the parts are ,combined and arranged accordin to the best mode' I have thus far ,35 devise for the practical application` of the principle of my invention.. Y
Figure 1 is a perspective view of 'a de- .vice embodying. my invention. A
Fi re 2 is a transverse vertical sectional I 4 view of the device showing a tooth brush in dotted lines in position to 'receive a supply of paste delivered or discharged from the tube. i
Figure 3 is an enlarged transverse vertical sectional view at ri ht angles to the position of Figure 2, throug the base of the device.
Fi re 4 is a horizontal transverse sectiona view through the .removable cup or casing, showin vin plan some of. the operating parts of t e device, and Figure 5 is a ,dispensing dental paste, andv is manually opview ,"showing an alternative method of e bracket 2 that is secured as by screws to the support W, which may be a wall or other substantial support, placed in position where it is readily accessible for use.
A second circular plate as 3 is combined with the base plate, and the latter is fashioned with a pair of complementary opposed top flanges 4, of arcuate shape for retaining the top plate 3 in position, and a aching plate 5 is preferably used between t e base and top plates as indicated in Figure 3.
The top plate at its center is provided with a receiving boss 6 to support the collapsible tube 7, and the externally threaded nipple 8 of the tube is designed to screw into the internal threads on the receiving boss. The collapsible tube may be of any of the usual standard' ty es readily procured in. the open market, and) is applied for use by locating it in upri ht position and screwing its threaded nip -e into the receiving boss as indicated in igure 3. For maintaining the tube in upright position I utilize a vertical back late as 9, which at its lower end is rigid `with the base portion of the dispenser, and at its upper end is provided with an an lar attaching flange 10 which is at- A tache as by screws to the wall W or other support that may be em loyed. The back plate is of amplle len -h or sup orting approxiinately t e ful length o the usual tube, and continues to support the foreshortened tube as the latter is rolled u on itself to compensate Jr'or the material discharged therefrom.
For sanitary andesthetic urposes as well as for assisting in the per ormance of the functions off the device, I provide a cap or cover l1 in the form of a cylindrical casing l1 having an open lower end that fits neatly 100 quired for changing t over the'iianged base plate and by frictional contact is retained on the plate. This enclosing casing for thetube, at its rear is fashionedwith vertical slot l2 which is open at the lower end of the casing which permits the casing to be slipped over the back plate, and the angular flange 10 of the back plate in its opposite edges, is provided with notches 13 to receive the walls of the rear slot 12. By this combination and arrangement of parts the cylindrical cap or casing has a rigid support against accidental displacement, but may readily be removed when ree paste tubes.
A second slot 14 is provided at one side of the casing, which also is open at the bottom of the' casing, to accommodate the key 15 of the tube, the key being used in well known manner to roll the material of the empty portion of the tube upon itself when the key is turned by hand for that purpose.
The removable cap, near its lower end, carries a pressure plate 16 located within its wall, and preferably curved to conform to the exterior periphery of the paste tube. The plate which stands in a vertical plane is designed to be moved laterally and isfashioned with a horizontally disposed rod or bar 17 slidable in a bearing boss 18 fashioned a't both the inner and outer sides of the casing wall. Exterior of the casing a push vbutton 19 is provided on the end of the push bar, and a spring 20 interposed between the push button and the boss 18, holds the pressure plate normally away from the tube and returns the plate to normal position after it has been operated to discharge paste from the tube.
The discharge of paste from the tube is governed by means of a slide gate 21 carried in a radially arranged slot 22 having bevel walls in the base plate. This slot eX- tends from the periphery of the base plate slightl beyond the center` of the plate, and an ori ce 23 is provided in the packin 'disk 5 alined with both the slot and the 'disc arge nipple 8 of the tube 7. The slide gate which opens outwardly from the center of the base plate is provided with a U-shape yoke 24 and the lower edge of the cap is notched to accommodate this yoke whose arms project 4inwardly towardthe center of the device. A
pair of springs 25 are attached to the yoke, and at 25 these springxs are attached to perforated ears 26 of t e top plate 3, in order that the springs may hold the slide gate in normally closed position and return it to normal position' after it has been opened to ermit discharge of the paste.
leans are provlded whereby the slide gate may be opened and a quantity of paste simultaneously discharged from the nipple 8 throu h the orifice 23 and the opened'slot 22. or this purpose a thumb or linger lever 27 'is employed and is located in position to contact with the push button of the pressure plate for actuating the plate and at the same time open the slide gate. rlhe lever is pivoted in front of the casing at 28 on a bracket 29 which bracket is rigid with the top plate 3, and the free end of the lever projects upwardly in position to actuate the pressure plate as shown in Figure 2.
Below its pivot 28 the lever has an arm 30 which has a slot connection at 31 with the slide gate in order that as the lever is pushed inwardly to actuate the pressure plate, the lever arms swings outwardly to open the slide gate. When pressure is removed from the lever, both springs 20 and springs 25 which have been placed under tension, assist in retracting the pressure plate, the lever and the slide gate to normal position.
Beneath the device is arranged a wire bracket 32 having a notch 33 for the handle 34 of a tooth brush 35, which when not in use is suspended from a hook 36 of the casing. For receiving a charge of aste from the dispenser the brush is place in dotted position shown in Figure 2 with the handle in the notch 33 and the brush beneath the slide gate. .'Ihe notch insures 'that the brush will be placed in proper position to receive the charge, and after the latter has been cut olf by the action of the slide gate it rests upon the brush for use in well known manner.
As an alternative method of securing the tube to the top ,plate 6 means shown in Figure 5 may be used whereby the threads 1n the boss are dispensed with anda spring 37 fastened to en age the threads of the tube is provided. e receiving boss is slotted on two sides as 38 permitting a V-shaped spring 37 to enter and make a positive connection with `the neck of the tube.

The combination with a base having a discharge orifice and a slide gate and means for receiving a paste tube, of a removable cap and a pressure actuated device carried thereby for coaction with the tube, a lever supported on the base for co-action with said pressure actuated device and connections between said lever and slide gate.
