TYPE-CLEANING DEVICE FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 781,581, dated January 31, 1995.

L pplic'ationfiled April 13,1904. Serial No. 202,945. a,

To a]! 1'71 om 'it n'btt cancel-1t:

Be it known that I, EnwannCiAnLnn, acitizen of the United States, residing at Uoatesville. in the county of Chester and State of Pennsylvania, have invented new and useful improvements in Type- Uleaning Devices for 'Type-ll'ritcrs, of which the followingfia a specification. f'

My invention --relates to a device for cleaning the vpe of a type-writer, and more par ticularly that kind which is attached to the platen and is adapted to be struck by the'type. Devices of this kind have been found to be objectionable, as by reason of their c6nstrue-' 5 tion and the manner in which they are secured to the platen they injure the type and throw them out of alinement.

The object of the inventionis to obviate this objectionable feature and also to provide a cleaner whichshall be simple, inexpensive, and thoroughlyeflicicnt.

A further object is to provide a cleaner which can be readily applied to an ,"'machine without in the leastaltering the (l nstruction thereof.

In the accompanying drawings, Figure 1 is a bottom plan view of a portion of the papercarriajre of a type-writer, showing the cleaner in operative condition. Fig. 2 is a cross-section on the line 2 2 of Fig. 1. 7

Referring specifically to the drawings, 5 denotes the paper-carriage of a type-writer, and 6 the platen, which has the usual paperlingers T for holding the paper. The cleaner is indicated at Sand comprises a strip of felt or similar fabric, which is placed on the platen and held thereon under the fingers T in the same manner as a sheet of paper.

in operation the keys will be struck as usual, which will-bring the faces of the type in contact with: the cleaner, the inking-ribbon the type. The fabric will be chemicallv prepared, a number of eiements'being' applied thereto which will render it effective for thoroughly removing and absorbingall jlirt, dried ink, and grit from the faces of the type when they are brought in contact therewith. The carriage will be fed along and the platen can ber'etated as when writing, whereby-a new wet-king surface is presented to the type, and thiis'eflables the entire surface of the cleaner to be utilized for the cleaning operation.

The cleaner has no metal or still' backing of any ltind and being-soft and pliant will thereforenot injure the type or throw it out of alinement as it is struck thereby, whichis frequently the case where a cleaner is used which is supported on a metal plate or a brush having a rigid hard back.

The device is readily applied and can be used on any machine withoutin the least altering its construction.

Having thus described my invention, what is claimed as new, and desired to be secured by Letters l atent, is-' 1. A cleaner for type-writers comprising a soft, pliant strip of absorbent fabric impregnated with a detergent compound and carried by the paper-lingers and rotatable with the platen. I

2. A cleaner for type-writers comprising a pliant strip of absorbent fabric impregnated with a detergent compound and constructed to lit between the paper-lingers and the platen, and rotatable with the latter.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
