FQLDABLE BRUSH.

Application filed March 16 1925.

To all who m, t may concern,-

Be it known that l, Vroron A. donnson, a citizen of the United States, and resident of Hartland, in the county of Nauliesha and State of Wisconsin, have invented certain new and useful Improvements in Foldable Brushes; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to foldable brushes.

Ubjects of this invention are to provide a foldable brush which may be q ..ielrly opened or closed, and which. will rock a plurality of bristles into outwardly projected position when opened, and will rock such bristles into overlapping fiat relation when closed, thus providing a very llat thin construction for the foldable brush.

Further objects are to provide a foldable brush in which the parts are so formed and related that they may be readily made by ordinary machine shop processes, and in which a plurality of similar members are employed, thus materially simplifying the construction of the foldable brush and permitting cheap and rapid manufacture there This invention is intended to supply a foldable brush which in actual dimensions and appearance corresponds to an ordinary cigarette case, and is adapted to be readily carried within the vest pocket without discounnoding the owner, and without requiring a material amount of room.

An embodiment of the invention is shown in the accol'npanying drawings, in which Figure 1 is a view of the brush in opened or extended position.

Figure 2 is a side view of the structure shown in Figure 1.

Figure 3 is a transverse sectional view on the line 32-? of Figure 1, such view being drawn to an enlarged Figure is a longitudinal fra; 'u1eiitary sectional VlOW on the line +l--lof ll lfi igure 5 is a view corresponding to i l ure 1, such View being drawn to an enlarged scale and showing more clearly the details of construction.

Figure 6 a view corresponding to a section on the line *3 '6 of l igure 3 with. however, the side flange omitted in order to show the end construction of one of the rocker bars.

Figure 7 is an enlarged transverse sectional View on the line 7-:? of Figure 5.

, Serial No. 15,897.

Referring to the drawings, it will be seen that the brush comprises a channel like body portion 1 to which is hingcdly secured a channel shaped cover The body portion 1 is provided with upstanding side flan es which may, if desired, be composed of an integral portion of the body portion 1, as shown in Figure 3, and is reenforced by members 3 in the form of elongated strips.

It is to be noted from Figure 3 that the strips 3 constituting a portion of the side flanges, project above the portion 1 of the body portion and thus are adapted to fit within the side flanges of the cover or top 2. These strips 3 may be continued across the end of the brush, as indicated at 3 in Fig ure 1 in order to secure a very firm construction, and to prevent any lateral motion whatsoever of the cover with. reference to the body portion when the cover is in closed position. A convenient way of pivotally joining the cover and the body portion is by means of rolled ears 4 formed integrally with the respective portions. These ears receive the elongated pintle pin 5, as shown in Figure 1 and thus permit free rocking motion of the cover with reference to the body portion. Preferably, a spring 6 is loosely coiled about the pintle pin 5 and has its ends bearing against the cover and the body portion in order to urge the cover towards open position, a clip 7, as shown in Figure 1 being provided for retaining the cover closed against the action of the spring.

A plurality of rocker bars 8 are provided and are positioned in parallel relation with in the body portion 1 of the device. These rocker bars are preferably die-cast and are formed with trunnions 9 at their ends which fit within the apertures in the side flanges 8. These rocker bars are preferably rounded throughout their major extent, but are provided with flat faces 10 against which cover strips or binding strips 11 are held by means of rivets 12 or other suitable fasteners.

It is to be noted from reference to Figures 5 and 7 that the rocker bars 8 are provided with recesses 18 which receive bunches of bristles 1d. Further, it will be seen from Figure 7 that the binding strips 11 are pro vided with inwardly pressed tongues or lips 15. These lips are adapted to project into the apertures 18, as shown, and to thus bind the inner ends of the groups of bristles 14:-

The squared portion 16 {see Figures 3 and which join the cover 2 t0 the body portion 1, as clearly shown in Figure 4. The outer end of the link 19 is pivotally joined to an ear 20 carried by the top 2.

In using the brush, the operator merely releases the catch 7 and the brush automatically opens into the position shown in Figures 1, 2, t and 5. It is to be noted that the parts 1 and 2 of the brush are prevented from further motion by contacting of the upstanding flanges adjacent the pivotal ears, as most clearly shown in Figures 2 and 4. During this rocking motion of the cover the link 19 is drawn outwardly thus simultaneously rocking each of the links 17 and accordingly rocking each of the rocker bars 8. This causes the bristles 1 1 to be p resented outwardly, as shown in Figures 1, 2 and 3. The operator now grasps the cover portion and manipulates the brush in the usual manner. lVhen it is desired to collapse the brush it is merely necessary to rock the cover over against the action of the spring 6 until the latch 7 engages in its corresponding recess. During this closing motion of the cover, the link 19 is pushed rearwardly and thus simultaneously rocks all of the rocker bars through approximately 90. This causeseach of the groups of bristles to lie in overlapping'or nested relation, and it is to be noted, particularly from Figures 1 and 5, that the groups of bristles are arranged in staggered relation for adjacent rocker bars, so that one group of bristles may lie between the adjacent pair of groups.

This construction, therefore, provides a foldable brush in which the parts may lie in a very compact manner when the brush is closed, and in which the britsles may be very quickly and easily projected outwardly in an automatic manner by merely opening the brush.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

I claim:

1. A foldable brush comprising a body portion, a plurality of rocker bars carried within said body portion, each of said rocker bars having depressions formed in one face thereof, bristles socketed within said depressions, a binding strip secured against said face and having inwardly projecting lips for clamping said bristles within said depressions, and mechanism connecting said rocker bars and said cover to cause simultaneous motion of said bars when said cover is opened and closed.

2. A foldable brush comprising a channelshaped body portion having side flanges, a

plurality of rocker bars having trunnions mounted within said side flanges, each of said rocker bars having one end thereof squared adjacent the corresponding trunnion, a lever having a squared opening fitting each of said squared ends, a link connecting the outer ends of said levers, a second link connecting said cover and said first mentioned link, and a plurality of bristles carried by each of said rocker bars,

In testimony that I claim the foregoing T have hereunto set my hand at l\filwaukee, in the county of lviilwaukee and State of lVisconsin.
