' p This invention relates to; attachments for typesetting machinesand particularly to a device especially designed". to be used on standard linotypes; the principal Object of my invention being to provide a device which will keep the reading faces of the matrices useddinfsuch machines in a continuously clean and legible condition, and without any attention on the part of the operator being a necessary other than anoccasional adjustment of the cleaningelement.' n j a p Another object is to provide a device for a the purpose which may be attached to the machine in but a few seconds time, and Withoutmaking' changes of any character to the machine.

A further object to construct device in'such a manner that While the-"cleaning '1 A-further 'ea; of as invention *is to produce a; simple and inexpensive device and yet :one which will .be exceedingly effective for the purpose for which it is designed. 7 These objects. lfaccomplish by -means of such structure and relative arrangement of parts as will fully appear by afperusal of the following specification and claims. j
