UNET@ HOWARD E. EVERETT, OF ST. PAUL, MINNESOT Danesa.
Application led April 3,
To 'all 'whom t may concern Be it known that I, HOWARD E. EVERETT, a citizen of the United States, residing at St, Paul1 in the county of Ramsey and State of Minnesota, have invented certain new and useful `Improvements in Daubers, of which the following is a specification.
My invention relates to daubers for applying blacking or polish to the surface to be polished, and more particularly to that typeI of daubers having magazine handles adapted to contain the blacking and also having handily operable means for distributing the blacking to the bristles of the dauber.
One of the difficulties met with in the construction of daubers of this type, is the evaporation of some ingredients of the blacking paste resulting in a hardening thereof, whereby the bristles become packed and `stiff and therefore useless.
Further, movable parts of the paste ejecting mechanism become gummed up and unmanageable.
It is an object of my invention to provide an improved dauber ofthe class described7 which is provided with humidifying ele'- ments both at the discharge end of the magazine and immediately above the volume of blacking paste within the magazine, so that gradual hardening of the paste at these points is prevented.
A. further object of my invention is thev provision of ejeoting mechanism of novel construction, whereby when the supply of blacking lpaste is exhausted, the ejecting mechanism will be rendered automatically ineffective, a certain disconnection of parts taking place whereby the user will be apprized of the exhaustion of the supply.
With these and other ends in view the invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.
in the drawings,
Figure 1, is a perspective view of my improved dauber.
Fig. 2, is a full sized side View of the invention, the lower portion thereof shown in section.
Fig. 3, is a vertical sectional view on a central line bisecting thedauber, the view being drawn to an enlarged scale and partly broken away.
Figs. 4:, 5 and-6 are detail views.
The invention comprises a hollow handle kportion 1, which constitutes the magazine, a
1922. Serial No. 548,962.
bristle supporting sleeve 2 and a closure cap 3. l
rlhe handle portion comprises a cylindrical container 4, of uniform internal diameter an d having an inset fiat top 5, whereby is formed the upwardly opening .circular shallowv cavity or chamber 6, over which telescopes by means of its annular downturned flange 7 the actuating cap 8.
Centrally the top 5 is perforated with a vcircular aperture 9. At its lower extremity the container is internally threaded as at a to threadedly engage with the sleeve 2, the upper circular edge 10 of the latter forming an internal shoulder in the bore of the container rllhe outer diameter of the sleeve is somewhat less than that of the container. the sleeve being spun down to form a restricted yneck or ferrule portion 11.- Firmly packed in the ferrule 11 are the dauber bristleslQ of approximately uniform length to form collectively a tuft having a flat end to facilitate application of the blacking, said bristles being packed around a centrally disposed tube 13 which forms -a discharge duct centrally of the body of bristles, said duct being in open communication with the interior of the container. Fitting telescopically and frictionally over the lower end of the container, and designed to freely receive the exposed portion ofthe sleeve and the protruding bristles, is the cap 3, the latter being formed preferably with a fiat top 14.
Frictionally held in the bottom of the cap and lying atly on the innerside of the top 14 thereof, is the absorbent element 15 having an inner face in parallelism with the fiat end of the bristle tuft, preferably of felt or other loose be-red material adapted to hold oil or water. I
By having the end of the dauber parallel with the humidifying element, all bristles are equidistant therefrom and are therefore evenly humidiied, which would not be the case if the dauber were rounded or conic in shape.' I have found that the 'greatest efficiency is secured with respect to applying blacking paste to a surface by constructing the dauber with bristles relatively short and stiff because of the character of the paste, which, when used in connection with long, thin bristles, overcomes the flexiblity of the bristles and forms a tuft of irregular shape. When the bristles arestiff and short the consistency of the paste cannot distort the tuft of bristles as a whole. With such resume its normal sliepen Ey making the bristles stiff and short" am also enabled to maintain a clear opening, as is best shownA in Figures l and 2', Which is in alinernent With the tube 13 and centrahofftheltuft, so.
that the humidifying element being also centrallyv disposed i relative ato said opening fW-ill hurnidify the interior Wall of said opening formedv bly. the` bristles. It am thus enabled to hu-rnidify.`-the tnft interiorly andI extesv riorlv, having, a relatively thin Walk of;
