- Application filed January 7, 1915. Serial No. 892.
citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Spindle- Head Brush-Holders; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention has for its object to provide a simple, economical and effective brush tip for bottle-washing macl1ines,its construction and arrangement being such as to dispense with screw-couplings, keys or-like de vices requiring time and delicate manipulation, such devices in practice having been found to -frequently work loose or jam under constant use.
Thus the generic object of my invention is to provide a coupling connection between the removable brush-head and tip, which connection may be eifected by snapping the elements together and confining them by a spring-controlled dog, the dog being incased within a spindle head to thus present no obstruction with reference to the diameter of said head.
With the above and other minor objects in View the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter withreference to the accompanying drawings and subsequently claimed.
In the drawing Figure 1 represents a sectional elevation of a brush-holder embodying the features of my invention, the section being indicated by line 11'of Fig. 2; Fig. 2,,a longitudinal sectional vie of the same, as indicated by line 2-2 0 Fig. 1, with parts shown in full; Fig. 3, a detailed crosssection through the spindle-head, the section being indicated by line 3-3 of Fig. 1, and Fig. 4c, a fragmentary sectional elevation of a portion of the head showing a modified form of coupling connection whereby the brush i rendered capable of oscillation with respect to the spindle-head.
Referring by characters to the drawings, 1 represents a tip or spindle-head that is internally threaded at its lower end for the reception of a water supply spindle not shown, it being understood that the head, in some instances, may be shouldered and exteriorly threaded for the reception ofthe spindle, without departing from the spirit of my invention. The spindle-head is provided with e a centrally disposed water duct 2 that communicates with a flattened rectangular end cavity 3 for the receptionof an eye t formmg the terminal of a brush-shank 5, whichbrush-shank in this exemplification of my invention is shown in the form of a wire, the strands of which are coiled about themselves to confine the brush-bristles that are fixed thereto in any desired manner and shape, it being understood that the brush construction forms no part of my present invention. I
v Referring particularly to Figs. 1 and 2, it is seen that the eye 4: substantially closes the end water duct 2 and to provide a bypass for the water, a channel 2 is provided in the head adjacent said end of the duct and com-' municating with the duct and with the said cavity.
The eye 4, as shown in Figs. 1 and 2, is formed with a rectangular end that is socketed into the cavity 3 and the cross-sectional area of the wire i of approximately the same dimensions as the width of the cavity, whereby side play of the brush is prevented within said cavity and, owing to the straight stretches of the loop eye which engage the ends of the walls of the cavity lateral play in this form of my invention is also restricted. The base section 4 of the eye is seated upon. the bottom wall of the cavity 3 and said'base section is confined by its engagement with a jaw 6 extending from the head 6 of a snapdog, the head being provided with a downwardly curved nose 6" which is adapted to be engaged by the bottom stretch l of the brush loop when the same is inserted within, the cavity. The snap-dog is seated in a lon gitudinal groove 7 that extends intermediate of the ends of the spindle-head whereby the dog is seated entirely within the line of said spindle-head, its outer edge being normally flush with the circular outer wall of the same. Thus the snap dog forms no obstruction in connection with the spindle-head to prevent its access to bottle necks or other articles in which the apparatus may be inserted. The dog also substantially closes the groove 7 to provide the retention of water in the duct 2. By this formation of the spin- (lle head, its manufacture by casting is greatly facilitated as the groove 7 and duct As shown in Fig. 1, the biting face of the jaw 6 is slightly inclined, whereby it will exert a downward drawing pressure upon the stretch t of the loop at all times to thus secure the brush firmly in its coupled connection with the spindle-head. The snapdog, as shown, is pivotally mounted within its receiving groove 7 by means of a pin 8, which extends through an aperture formed in the spindle-head. The snap-dogis also provided with a tail-piece 9 which forms a continuation of the body of the dog and between the end of which tailand its head the fulcrum is positioned. The tail-piece is providedwith a web-lug9 that extends into a transverse aperture 10, into which aperture is fitted a coiled spring 11,,being under compression between the base of said. aperture and the web-lug 9 of the gripping dog. Thus it will be seen that the gripping dog is held under spring tension at all times. In order to manipulate the gripping dog when it is desired to remove the brush for renewal or other purposes, the circular outer wall of the spindle-head is formed with a crosschannel 12 constituting a thumb-seat, whereby a portion of the gripping-dog tail is exposed. Thus by this means access is had to the tail of the gripping dog by the operator to force the lower portion of said dog inward in opposition to its pressure, whereby the head will recede from its normal seated position across'the rectangular cavity 3 to free the eyed shank of the brush from the spindle head.
From the foregoing description it is obvious that a brush having aneyed shank can readily be slipped into the mouth of the cavity 3 and as it is pressed downward to its seat, the curved nose of the gripping dog head'will recede and when the stretch 4 of the eye has seated against the bottom of the cavity the dog will, through its spring pressure, automatically snap back to effect the desired coupling.
In some instances it is desirable to permit oscillation of the brush in one direction and, in order to effect this result, I may, without departing from the spirit of my invention,
- contract the loop 4, as shown in Fig. 4 of the drawings, in such manner that the side stretches 4 are brought together so as to permit play of the brush shank with relation to the end walls of its seating cavity 3. It is also apparent that, owing to the rectangular seat 3 being of such width as to only accommodate the width or dimensions of the loop wires, there is no appreciable liability of the brush to have side play, whereby it might otherwise inadvertently become uncoupled.
The combination with a brush having a shank provided with an opening of a spindle head provided in one side with a longitudinal slot extending inwardly of the axis of the head and forming at its inner. portion a water duct, the head being provided in oneend with a socket communicating with and extending transversely of the slot for receiving the shank, the head being formed with a channel communicating with the socket and slot and a dog pivoted longitudinally in the outer portion of the slot and engageable in the opening of the shank to hold said shank in the head, said dog also serving to siibstantially close the outer portion of the s 0t.
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.
