Our invention relates, to a type.v cleaning brush, more particularly for use in cleaning the type in connection with thelreys on a type-writer; and the o'bjects'of our invention are:

First: T'o-provide-a brush ofthis class which is" particularly adapted for use in reaching the type of a typewriter and for cleaning the same by'rot-atingsaid-brushoverthe type. 7

Second? To provide a type cleaning: brush. or this: classzhaving novel solvent dispensing means in connection therewith arranged to deliver the solvent: to: saidbrush as -i't is rotated'overthe ype wherr'cl'eaningthesainea Third: sire provide-la: type cl'eaning br-ush of thisv cl'assfwhaving.angulanaxes: at the! opposite ends .of-th'e': bristle bearing axis. for providing lateral: movement. of .the brushduring rota-tion.

Fourth: To. provides... type, cleaning brush of this class which is very easy to operate and very thorough in its cleaning-operation.

Fiftir: To provide-a type cleaning brush of this class having anovel handle solvent reservi'or and tubular shank f'or feeding "cleaning fluid to the bristles of the brush during rotation in connection with the type being cleaned.

Sixth: To provide a type cleaning brush of this class which is very simple and economical of construction, efficient in its action and which will not readily deteriorate or get out of order.

With these and other objects in View as will appear hereinafter, our invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, forming a part of this application in which:

Fig. 1 is a longitudinal sectional viewof our type cleaning brush showing portions in elevation to facilitate the illustration, and showing by dash lines the structure of the typewriter associated therewith in cleaning operations. Fig. 2 is a fragmentary side elevational View of our type cleaning brush. Fig. 3 is a fragmentary sectional view taken from the line 33 of Fig. 1. And Fig. 4 is a side elevational View of the axle and bristles of our type cleaning brush showing in detail the angular axial portions at opposite ends of the axle of said brush.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

The bristles I, axle 2, tube 3 and the handle 4 constitute the principal parts and portions of our type cleaning brush.

The bristles I are preferably: resilient: bristles of any suitable material desired and. these bristles I are secured in connection with the-axle 2 between the twisted? wire pontions-Zm and.;2b whi'cl'i form said axle 2 :aseshown. best ingEi'g; ofthedrawing; "the bearing portions 2c: and- M 0t this axle: Z are. in parallel; angularly dis: posed relationwith the axis: of: the bristle-retain..- i-ng' portion: Ze at. the middle of the: axle 2; it; being. noted that the. bristles. l:- radiate; from; thegaXiS of the" axle shown in Fig. .3: of: the, drawing; @fppgsi te. gndsjjz'g andfzdf. ofither axle. 2. a e? iQ l nailed? inv connection with. the handle- 4; by:means or the bracketfBgm .fusedilto. thee-tuber 3: is flarertati its upper ended-r1 in; connection withithe enlarged handle-5 enciose at: the-upper: endb the plug. 4m whieh'tmay: bea secure d; in connection with said handIe;--a --by various-means: aszdesired-v The lower end of the tube 3 is flat as she in Fig. 3: or the; dmawing: providing; a: narrow! outlet portion-.3 bsthrouglr wh-i idi. mawpass, from; the retainer S ain;- the tub. a all as. hown: bestin- Eigsr. 1: andve or the drawing: Theflu d; re net. in thetu-be. 3s mayr.be:.=ie lt on other; it b e; material for suspending the fluid therein which is stored in quantity in the hollow tubular handle 4 providing sufficient supply for complete cleaning operations of the type in connection with the typewriter.

The operation of our type cleaning brush is substantially as follows:

Fluid is first placed in the hollow cylindrical handle 4 and the plug 4a inserted in the end thereof enclosing the fluid in the handle- 4 in contact with the retainer 30 in the handle 4 and the tube 3. The density of this fluid retainer 30 may be varied as desired by substituting various materials such as felt, etc. The fluid in the handle 4 gravitates through the fluid retainer 30 in the tube 3 and is distributed through the opening 31) in the lower end of the tube 3 contiguous with the bristles i of the brush. As the brush is rotated over the type of the typewriter the angular and portions 20 and 2d of the axle 2 cause lateral movement of the bristles I together with rotative movement while the bristles I are passed over the type. It will be noted that the fluid passing from the handle 4 to the tube 3 passes slowly in connection with the retainer 30 providing the proper flow of fluid to the brush bristles l in accordance with the usage and evaporation thereof. The tube 3 is provided with an angular portion near the brush for access to the type.

Though we have shown and described a particular construction, combination and arrangean axle and with bristles radiating therefrom, a

hollow handle connected to said brush having a tubular portion with one end in close proximity to said bristles, retainer material in said handle and said tubular portion arranged to retain fluid therein, said brush rotatively mounted on said axle in spaced relation with said handle and having angularly disposed axle portions disposed in opposite directions near the ends thereof, arranged to cause said brush to wobble during rotation.

2. In a type cleaning brush of the class described the combination of a hollow handle, a tubular portion extending therefrom, a rotatable brush connected to said handle and in close proximity with the open end of said tubular portion, a fluid retainer in said tubular portion arranged to retain fluid and conduct the same to the bristles of said brush, said brush provided with an axle having angularly oppositely disposed end portions revolubly mounted on said axle in spaced relation with said handle arranged to cause said brush to wobble transversely of the axis thereof during rotation, said handle provided with an angular portion adjacent the brush portion adapted for use in convenient access to the keys of a typewriter.

3. In a type cleaning brush of the class described, the combination of a handle, a brush rotatably mounted connected to one end thereof, said brush provided with an axle having oppositely disposed angular ends mounted in bearings in 4 said handle, whereby said brush tends to wobble relatively with said handle when rotated.

4. In a type cleaning brush of the class described, the combination of a brush composed of an axle and radiating bristles, a hollow handle connected to said brush, having a tubular portion with one end in close proximity to said bristles, retainer material in said handle and said tubular portion arranged to retain fluid therein, said handle provided with a curve in said handle near its connection with said brush, to facilitate the operation of said brush in cleaning the type of the typewriter.
