B R U S H SZ EOIFIGATIQN forming part of Letters Patent No. 691,032, dated January 14, 1902. Application filed March 22, 1901. Serial No. 52,293. (No model.)
To ctZZ whom it may concern:
Be it known that I, ADOLPH R. \VIENS, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements in Brushes; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention has for its object to economically provide brushes having automatic-feed reservoirs that are preferably valve controlled and which in some instances are also serviceable as staff-sockets.
The invention has especial reference to what are known to the trade as dustless sweeping-brushes; and it consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.
Figure 1 of the drawings represents a transverse central section of a brush and reservoir attachment in accordance with my invention; Fig. 2, a plan view of same, partly broken away and in section; Fig. 3, an elevation of the brusl1,partlyin longitudinal section,a portion of the reservoir being shown in connection with the brush-head; Fig. 4C, a detail sectional view of a portion of the reservoir-neck; Fig. 5, a detail sectional view, indicated by line 5 5 in the sixth figure; and Fig. 6 an elevation of the socket-fitting end of a staff for the brush.
Referring by letter to the drawings, A indicates the brush-bacl ,p1'ovided with sockets, into which tufts B O are wire-drawn in the usual manner or otherwise secured, the butts of the tufts 0 being exposed in a longitudinal channel of said back. A cover D is made fast on the back by screws or other suitable means. In practice it is preferred to treat the opposing surfaces of the back and cover with a cement, that will insure a tight joint against water, oil, or other liquid used with the brush.
When the brush is organized for dustless sweeping,the tufts B are of non-absorbent material and the tufts G of absorbent material, these materials being such within the knowledge of brush=makers as are most suitable for the purpose, kerosene, gasolene, or other suitable more or less volatile oil being supplied to said absorbent tufts from a reservoir E, hereinafter more particularly described as an attachment of the brush, in communication with the back channel in which the butts of the aforesaid absorbent tufts are exposed.
The tufts Careshown as having their butts provided with feed-passages b for the liquid that flows from the reservoir E, these passages being obtained by piercing the butts with wires longitudinally thereof and treating said tufts with material that will solidify the same in their sockets aroundthe wires, the latter being withdrawn when said material has set. \Vhile this is a preferred construction, especially in the manufacture of dustless sweeping-brushes, it is not an essential of my invention.
The reservoir E is preferably metallic and is herein shown as being for the most part in the form of a bulb to thereby increase capacity in proportion to its length. The lower end of the reservoir is in the form of a plate 0, having a depending nozzle 01, that extends screws 6 or other suitable means, and reservoir-nozzle d discharges into the back channel aforesaid. It is preferable to provide the plate with a central too that laps the cover D ora solid brush-back, and is embedded therein to thereby prevent strain that might otherwise come upon the fastening devices for said plate, these devices being arranged in opposite directions from a line transversely of the aforesaid plate central of said toe.
The reservoir-nozzle is shown as having an apertured plug of soft metal, into which the point of a pin-valve F is primarily forced to form a seat, the plug-aperture being closed by said valve. The valve is cranked and pivotally held between ears h on the lower end plate (2 of reservoirE adjacent to a play-slot in said plate for said valve, a spring at being arranged to: automatically hold the valve to its seat. The power of the spring is sufficient to cause the valve to embed in soft-1netal plug g particles of grit or other minor obstructions that might otherwise interfere with its proper seating, perfect automatic seating of said valve being a matter of considerable importance, especially when kerosene or gasolene is stored in the reservoir. However, valves are not always essential to brushes provided with reservoirs similar to that herein disclosed.
The reservoir E is shown provided with a tubular neck j above an inner annular seat 70, and an inner inclined lug m is provided in the upper portion of the neck for the engagement of a spiral groove 71 in a stopper that preferably has the form of a staff G, the lower end portion of this stafi being slabbed, as shown at p, to clear said lug and permit of the latter being engaged with said groove when said staff is inserted in the reservoirneck, that constitutes a socket. A plug H, of suit-able compressible material, is made fast on the lower end of staff G to abut the seat 70 in the reservoir-neck, and an engagement of neck-lug m and staff-groove n having been effected a turn of said staff will result in a compression of the plug on said seat to effectually close the reservoir aforesaid.
Various means may be devised for closing the filling-aperture in the reservoir whether the latter is valve-controlled or otherwise.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A brush-back provided with a channel open to tuft-butts, a reservoir attachment provided with a nozzle having an apertured soft-metal plug therein, a pin-valve primarily seated by force in said plug to close the aperture of same, and a valve-controlling spring of sufficient power to reseat the valve from time to time against resistance of obstructing particles that may find their way into the seat.
2. A brush-back provided with a channel open to tuft-butts, a reservoir attachment having anozzle that leads to said channel, an
inner end of the stopper being compressible against said seat.
3. A brush-back provided with a channel open to tuft-butts, a reservoir attachment in the form of a bulb havinga nozzle leading to said channel and a tubular neck, an inner annular seat at the junction of the bulb and neck, an inclined lug in the upper portion of the neck, a stopper having a slabbed end provided with a spiral groove, and a compressible plug in connection with the stopper to abut the aforesaid seat.
4:. A brush-back provided with a channel open to tuft-butts, a reservoir attachment having a foot-plate provided with a toe embedded in the brush-head, a nozzle depending from the foot-plate into said channel, and
fastening devices extended through aper-' tures in said foot-plate in opposite directions from a line transversely of the same central of its toe.
5. A brush-back provided with a channel open to tuft-butts, a reservoir attachment provided with a nozzle leading to said channel, a foot-plate, and a spring-controlled valve in pivotal connection with plate-ears.
6. A brush-back provided with a channel intercepted by sockets, and tufts having solidified butts in said sockets provided with longitudinal passages.
7. A brush-back provided with a channel intercepted by sockets, tufts having solidified butts in said sockets provided with longitudinal passages, and a reservoir attachment having a nozzle leading to said channel.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
