Application filed June 13, 1921. Serial No.477,141.

T0 allwhomz't may concern: p j

Be it known that I, VVILIJAM J. IWAMI, a subject of the Emperor of Japan, and resident of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Typewriter Attachment, of which the following is a full, clear, and exact description. I

My invention relates to a typewriter attachment, and aims to provide a device of this nature by means of which the type may be cleaned.

It is a well appreciated fact that heretofore it has been necessary to clean the faces of the type in a writing machine at frequent intervals, incident to the fact that the type becomes clogged with particles of ribbon, dust, etc. rendering the impression made by the type blurred. This cleaning operation necessitates the use or" a brush or a sharp pointed instrument, together with a suitable cleanin fluid-to effect a dislodgment of the particles. v

Aside from the time necessary for the accomplishment of the type cleansing, considerable diliiculty has been experienced in that the operators fingers become soiled, incident to the ink from the ribbon rendering the operation an extremely unpleasant one.

Having these defects in mind, my present invention aims to provide a typewriter attachment by means of which the type may be thoroughly and quickly cleaned without the necessity of soiling the fingers.

A further object of my invention is the construction of a device of the nature specified which may be placed upon the market at a nominal figure, and further objects of my. invention will appear in the annexed specification taken in connection with the drawings which latter present practical applications of the same, and in which;

Figure 1 is a side view of an attachment embodying myimproved construction and showing the same in one association.

Figure 2 is an enlarged end view thereof.

Figure 3 is a rear view of a slightly different form of attachment than that illustrated in the precedin figures.

Figure 4 is an enlarged transverse sectional view taken along the line M and in the direction of the arrows indicated in Figure 3.

"Figure 5- is a planview of still another adaptation of the attachment, and- Specification of Letters Eabznt. Pctbflll'tfili Acilg, 15,

Figure 6 is a perspective view of the de vice as illustrated in Figur'e'5.

Referringv now more particularly to ures '2 and i, it will be 'seen'that the essence of my invention consists in the utilization of a brush element against which the type to be cleaned is struck. Thus, the reference numeral 10 indicates a base upon which a backmg 11 carryingbristles 12 is removably retained, preferably by means of a clamping Figi ring 18, thus rendering the brush portion of the device renewable when the same becomes worn. f

As in Figures 1 and 2thebase 10 has secured to it a rearwardly extendingclip 14 by means of which it may be detachably associated withthetype head 15 secured toany type bar-'16, forming a partoi the conventional typewriter action.

1 Thus when an operator desires to effect a cleaning of the type it will. only be necessary to project one of the type bars by striking one of the keys 17, subsequent towhich the brush element maybe associated with the head 15 by means of the clip 14. By reother keys may now be struck, and by virtue the cleaning element is associated occupies a central position, each of the type subse quently projected by pressing" the 'corre spondm'g keys will strike against the bristles 12 thus freeing the particles of matter lodged within the face "of the type and cleaning the latter. 1 It will be found that, all thus be readily cleansed "withthe' expendiof the type may j ture'of but a min'imumamount of time and 1 it will also be seen that thefingers of the operator will not be soiled as has heretofore resulted from the accomplishment of this cleaning operation, it being of course understood that after the same is completed, that the base 10 is detached from that type head with which it has been associated, and the" key of thelatter released. I

In Figures 3 and 4L 1 have shown the cleaning element as forming a permanentpart of a typewriting machine, i. e. one or" the type bars devoted exclusively as a permanent mounting for the cleaning element thus rendering the attachment and detachment of the latter unnecessary.

Finally the type illustrated in Figures 5 and 6 it will be seen that the cleaning element aforedescribed is attached to the outer end of one 01" a series of links 18 hingedly interconnected these links When in folded position lying as has been indicated in dotted lines in Figure 5 flush against the body of the typewriting machine, but being capable of beingswung so that the cleaning element Will lie in advance 01"- the type gap so that obviously any type projected will strike against the same and be cleansed.

Thus all of the objects set forth in the preamble of this specification have been accomplished and it will be appreciated that numerous modifications of structure might readily be resorted to Without in the least cleaning element and supporting means for i said cleaning element said supporting means being adapted to be'associated' With a typewriter whereby said cleaning element may be moved to a point adjacent the type guide of said typewriter to permit of the type 00,- acting therewith.
