FELT-CLEANER FOR PAPER MACHINERY.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed August 24, 1904. Serial No. 221,915.

To aZZ whom it may concern:

Be it known that I. MATTHEW MILLER, a citizen of the United States, residing atUpper Darby, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Felt-Cleaners for Paper Machinery or the Like, of which the following is a specification.

My invention relates to a device for cleaning the felt or apron, usually known as the felt, used in machinery for manufacturing paper. Heretofore it has been necessary to remove the felt from the machine and submit it to a cleaning process for several hours to remove the particles of pulp and other objectionable matter which would collect in a few hours of operation of the machine, which method was very laborious and expensive.

The object of my invention is to provide means for cleaning the felt without removing it from the'machine.

A further object of my invention is to construct the cleaner in such a manner that the same may readily be brought into use during the operation of the machine.

A still further object of my invention is to provide means of adjusting the parts of the cleaner, together with various features of construction, which will be hereinafter fully set forth and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of a portion of a paper-machine, showing my invent-ion attached thereto. Fig. 2 is an inverted plan view of the steam-pipe shown in Fig. 1. Fig. 3 is an end view of Fig. 2.

In the drawings, A represents the side frames of the paper-machine, B and B compression-rolls, and C the felt, which is continuous in form, running throughout the machine and upon which the pulp is carried through the different rolls to form the finished paper.

D represents a water-pipe held in brackets (Z on the frames A. This pipe is provided with a series of perforations on its under side and is used to force jets of water upon the felt to soften it and prepare it for the cleaner.

The cleaner consists of the pipe E, held in brackets e in the frames A, and steam-supply pipe E, connected to the pipe E. The steamfpipe E is provided with a slot E the length of which is equal to the width of the felt G. The pipe is placed so that said slot is on the under side of the same and said pipe located immediately over the felt, so that when steam is emitted from the pipe it will be directed toward the felt C. To regulate the amount of steam that is emitted from the pipe E, 1 provide clamps F, by which the pipe may be contracted to less than its normal diameter and the width of the slot varied by the adjustment of the wedge G, held in a groove formed in one side of the clamp F. A space is left between the ends of the clamp F, so that the clamp will not cover the slot E or interfere with the emission of the steam from the pipe. The clamp is made of heavier metal than the pipe E, so that when the Wedge is tightened the clamp will remain rigid and the pipe will yield and cause the slot in the pipe E to close.

The operation is as follows: The paper is cut so that it will not be fed through the machine upon the felt, which is running continuously. Water is admitted to the pipe D, which sprays the felt and softens it. then travels under the steam-pipe E, where it is subjected to the steam, which is presented in a continuous sheet throughout the entire width of the felt. The felt is thus thoroughly cleaned and prepared to again to receive the paper.

If so desired, another wedge may be added to the other side of the ring F to give a more perfect adjustment. A set-screw, as shown in dotted lines, Fig. 3, may be used in place of the wedge to vary the width of theslot E without departing from my invention.

Having thus described my invention, Iclaim and desire to secure by Letters Patent* 1. The method of cleaning felt in a papermachine, by spraying the said felt with water to soften it and then subjecting it to a fluid agent under pressure to remove the objectionable particles, substantially as described.

2. In combination with a machine in which felt is used, a perforated pipe located adjacent to said felt, a water-supply pipe connected to said perforated pipe,- a pipe having a slot formed therein located adjacent to said felt, a

The felt v steam-supply pipe connected to said slotted steam-supply pipe connected to said slotted 10 pipe and hearings to support said above-mentioned pipes, substantially as described.

3. In combination Witha machine in Which pipe and bearings to support said above-mentioned pipes.

In testimony whereof I aifix my signature in felt is used, aperforated pipe located adjacent presence of two Witnesses.

to said felt, a Water-supply pipe connected to i said perforated pipe, a pipe having a slot formed therein located adjacent to said felt, means for varying the Width of said slot, a
