Application filed October 8, 1917. Serial No. 195,300.

To all whom it may concern:

Be it known that I, CHRISTOPHER A. GAR- vEY, a citizen of the United States of Amen ica, resident of Clayton, St. Louis county,

State of Missouri, have invented certain new and useful Improvements in Brushes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in brushes, and more particularly to means whereby a brush tip is adjustably secured to a tip holder.

been experience in adjusting such material to suit the user of the brush, or to conipensate forthe wear to which the brush is subjected in service. For example, fountain type known as marking usually include a tip made of felt or other yielding absorbent material, and it is frequently necessary, or desirable, to adjust the tip relative to its holder.

(Inc of the objects of the present invention is to enable the brush tip to be easily adjusted, either into or out of its holder, so that the user of the brushean adjust the tip in either direction. When the tip is shortbrushes,

ened by wearing away in'service, it can be advanced away from the tip holder, and if the adjustment is not entirely, satisfactory, the tip can be very accurately adjusted in either direction to enable the user to obtain Another object is to firmly secure the adjustable tip in its holder, so that it will not be accidentally pushed into or out of the holder when the brush is in'service.

With the foregoing and other objects in view the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention; however, it is to be understood that the invention comprehends I changes, variations and modifications which come within the scope ofv the claims hereunto Figure I is a side elevation of a fountain Brush tips are necessarily 15 made of'yielding material, and difiiculty has cylindrical rod.

brush, embodying the features of my invention.

Fig. II is an enlarged vertical section of the lower portion of the fountain brush.

Fig. III is a view similar to Fig. II,

showing the small outlet passagewaysat opposite sides of the brush tip.

Fig. IV is a transverse section taken on line IV-IV, Fig. III.

Fig. is an inverted plan view of the brush.

To illustrate the invention, I have shown a fountain brush adapted to be used like a pencil, in making signs, lettering boxes, pa per cartons, etc. 1 designates the reservoir for the ink, or other fluid, and 2 designates a yielding brush tip arranged'in the outlet below the reservoir.

A discharge device A, screwed into the lower portion of the reservoir, is provided I with a packing chamber 3, a relatively large passageway 4, and a tip. holder 5 screwed into the lower end of the passageway 4. The liquid passing from the reservoir flows through a passageway 6 at the upper end of the discharge device, through the packing chamber 3 and hollow screw 7, to the large passageway 4, and'thence to the tip 2 in the tip holder 5. The pac 'ng chamber?) may contain an expansible spring 8- secured to a body of absorbent packing material which retards the flow of ink from the reservoir, as pointed out in Patent No. 1,182,554, issued to me May 9, 1916. However, it is to be understood that the present inventionis not in any way limited to a means for regulating or retarding the flow of ink from the reservoir to the tip. v

he tip holder 5 is preferably threaded internally as shown at 9, to provide a spi- The brush tip 2 is made of yielding material, preferably tough fibrous absorbent material, such as felt, and it is preferably in the form of an elongated, so closely fitted to the screw thread 9, that a corresponding thread is formed in the yielding material, as shown in Figs. II and III. It is to thread in the ielding tip can be readily This yielding brush tip is understood that the screw adj ust the tip 1n either direction. When the it will advance of the screw thread, thus tip is turned in one direction, longitudinally moving into the holder, and if turned in the opposite direction, the tip will advance-outwardly from the holder.

Obviously, the yielding tip can be very accurately adjusted in either direction to enable the operator to obtain most satisfactory results. -A new tip can be readily applied to the holder, and owing to the manner in which the tip meshes with the screw threads, it is securely interlocked with the holder and will not, slip in either direction when the brush is in service. Y

The internal screw thread 9 is preferably mutilated, as shown at 10 (Figs. llll and'lV) to provide relatively free outlet for the ink flowing from the reservoir to the lower end of the tip. The thread can be mutilated by v merely slotting the charge device having a intern ally holder, as shown most clearly at 10 in Figs. 1 and V.

I claim 1. A fountain brush comprising a disdhargedevice provided with an'unrestricted outlet having an internal screw thread, and a yielding brush tip in the form of a cylindrical rod of fibrous absorbent material, said rod being closely fitted to said internal screw thread and being movable longitudinally of said screw thread so that it may be rotated and adjusted into or out of said outlet.

2. A fountain brush 'tip holder at one of its ends, said tip holder being screw threaded a yielding brush tip in the form of a cylindrical rod fitted to the screw thread in said tip holder, said tip holder being slotted inwardly from its outer end-to permit free flow of liquid from said reservoir to the surface of said tip.
