This invention relates to an applicator unit for applying to any desired surface a suitable type of viscous or semiviscous material which is especially adapted for use in applying material to a persons lips.
One of the objects of our invention is to provide an applicator unit which is readily separable so that different types of materials can be utilized, preferably by an interchange of that part of the unit carrying the desired material whereby various fields of usefulness will be served.
Another object of our invention is to provide an applicator unit in which the material can be extruded in definite or pre-determined quantities.
Another object of our invention is to provide an applicator unit in which the extrusion of the material can be accomplished in a very easy and positive manner.
A further object of our invention is to pro vide an applicator in which the material can be disbursed in an easy and uniform manner'over the surface to be covered.
These and other objects w ll be a parent from a reading of the following specification taken in connection with the annexed drawing wherein:
Figure 1 is a part sectional and part elevational view on an enlarged scale of our improved applicator unit.
Figure 2 is a perspective view of the ratchet and operating member shown in Figure 1.
Figure 3 is a part elevational and part sectional view of the lower portion of a modified form of construction.
Figure 4 is a view on the line 44 of Fi ure 1.
Figure 5 is a sectional view of a modified form of a brush arrangement.
In the various views herein, like numbers refer to corresponding parts. I is a supply chamber having a conically shaped end 2 which carries a member 3 fastened thereto as by screw threads 33 for supporting a brush 4 made up of a plurality of brush elements seated in the base The member 3 has an opening 6 around the brush 4 to allow the material to be extruded from the chamber I The brush 4 when not in use has a cap 1 for protecting it. As shown, the cap 1 is fastened to the supply chamber I in any satisfactory manner as by screw threads 8, but it may be held in place by a push fit.
'--The supply chamber l is carried by a support a chamber 9, the union between the two being such that the chamber I may be readily removed from the chamber 9. As illustrated in the drawing,
a collar In is utilized for this purpose and is attached to the chamber 9 in a satisfactory manner as by fine pitched screw threads H. The supply chamber I may be attached to the collar I0 by relatively course screw threads l2 so that the chamber I may be easily removed from the collar [0 without disturbing its position on the chamber 9. This arrangement is such that a piston l3 normally positioned at the lower end of the supply chamber I may be assembled therein. Extending downwardly from the piston I3 is an elongated ratchet member I having a plurality of pawl engaging surfaces [5 which are preferably circular and equally spaced one from the other for a purpose which will be later pointed out. Located at the extremity of the support chamber 9, opposite the collar In, is an operating member i6 which carries a plurality of pawl arms H, the free ends 18 of which are curved inwardly toward the ratchet member i4 and in cooperative relationship with a curved surface 18 on the collar l0, whereby when the operating member I6 is pushed inwardly, the ends l8 of the pawl arms i! will be forced inwardly into engagement with one of the ratchet surfaces I5, thereby pushing the ratchet member and piston member l3 upwardly to extrude a definite amount of material through the opening 5 onto the brush 4 for application to any desired surface. The member l6 has an inwardly extending flange 20 to engage an outwardly extending flange 2| on the supporting member 9. These flanges 2B and 2| are relatively short so that the member Hi can be easily assembled into position. The member [6 has a recess 22 therein within which is located, a spring 23 for returning the operating member [6 to normal po sition after it has been pushed upwardly for the extrus on of the material as previously described.
The collar l0 carries a resilient clip 24 which will snap under an engaging surface l5 asthe ratchet I4 is pushed upwardly by the pawl arms I! and will thereby hold the piston IS in its operative position. Each ratchet surface 14 is provided with a notch 25 so that by turning the elongated ratchet member l4 through an angle extra supply chambers I.
be put into the chamber 1.
In Figure 3 the operating member 26 has an annular flange 21 that is engaged by the flange cup-shaped member 28 for holding it in position on the support member 9. The same type spring 23 being used as in Figure 1, for returning the member 26 to normal position.
In Figure 5, a different type holder 29 is utilized for holding a modified form of brush 30. In this form of construction a hole 3| is positioned so that the material is extruded outwardly on the axialcenter of the unit through the center of the brush 30, and directly to the point of the brush. For certain classes of work this type of brush arrangement is advantageous.
Whil we have shown the major parts of the applicator as being made out of a suitable metal, such as aluminum or an alloy thereof, these parts may be made of a suitable plastic material and other details may be varied. For example, the connection between the collar i6 and the chamber 9 may be by a coarse pitched screw thread and the supply chamber i may be .attached to the collar 18 'by a fine pitched screw thread whereby the chamber l and the collar along with piston is and attached member I4 may be removed as a single unit from the chamber 9, permitting easy and rapid interchange of diiferent types of materials.
By changing the ratchet member 14 along with the supply chamber I, as above described, this.
saves the cleaning-up operation on the ratchet member if the same type or color of material is to beutilized, it being understood that if any of the material of one color gets past the piston 13 onto the ratchet member M the same should be cleaned if a different'color of material is to With this arrangement, the cap 1! may 'be'made of sufiici nt length so that it may be screwed onto the threads ll of the collar is when it is removed from the chamber 9 so as to enclose and protect the ratchet member M which is withdrawn as just described with the collar it. When the cap i is utilized as just described, then a small cover 32 is used to protect t e brush 30 as illustrated in the dotted lins in Figure. 5.
Having thus described our invention, what we claim is:
