Application filed Getobei 27, 1920. Eerial No. 420,067.

exact description, reference being had to the accompanying drawing, this specification.

My invention relates to improvements in forming a part of means for cleaning-fabrics and has particular reference to devicesadapted-to clean what is known in the art as tire liners.

I Une of the objections to the of I111.- chines heretofore used for this purpose is that after a certain amount of use the edges of the vacuum nozzles-become Worn and roughened whereby the fabric, in being drawn over these nozzles is torn or split. As these fabrics are made in long lengths and as the slightest roughness or tear in a length destroys the value of the entire fabric, it is desirable to provide means whereby the danger of tearing the same is obviated.

It is one of the objects of my invention to provide means whereby the wear on the nozzles may be taken care of and a smooth nozzle surface always be provided.

For the purpose of disclosing my inven tion I have illustrated one embodiment thereof in the accompany drawings in which Figure 1 is a side elevation of a cleaning apparatus embodying my invention-part of the same being shown in section;

Fig. 2 is a plan view thereof;

Fig. 8 is a sectional view of one of the tubular nozzles showing the wear plate in position;

Fig. 4 is a perspective view of the wear tube or plate;

Fig. 5 is a sectional view of one of the nozzles showing the modified form of wear plate, and

Fig. 6 is a perspective view of one of themodified wear plates.

In the embodiment illustrated, upon a suitable table or bench 1 is mounted a pair of rollers 2 and 3 and these rollers are mounted at opposite ends of the bench and may be removably mounted if desired. The fabric is wound on one roll, the roll 2, and is unwound. therefrom on the roll 3, a suit able driving pulley a being provided on the shaft of the roll for operating the mechanically.

Extending transversely of the bench and in the path of the fabric as it passes from one roll to the other, is a cleaning apparatus., This apparatus consists, as shown, of a pair of horizontally disposed transversely roi 1 extending tubes 5 and 6 arranged one in front of the other and one preferably in a lower plane than the other. Each of these tubes is provided with a longitudinally extending slot 7 in the face thereof. The slot in the-tube 6 is towards the lower portion of thetubeandthat in the tube 5 in the upper portion of the tube so that as the fabric is drawn between the tubes, it passes underone tube and then takes a path upwardly and over the other tube. These tubes preferably take the form of pipes and are supported in position by suitable brackets or heads 8 one on each side of the bench.

The opposite ends of the tubes are connected with branch pipes 11 each of which is closed at one end by a suitable nipple or nut 12; the opposite end being connected to a communicating pipe 13 by suitable elbows 14. One of the branch pipes 11 is provided with a coupling 15 by which it is connected by means of a pipe 16 with a suitable vacuum producing device 17 preferably driven by an electric motor.

In the operation of the device so far. described, the fabric is passed beneath one pipe and above the other and due to the connection of the vacuum producing device 17 with the two pipes air is drawn through the fabric as it passes over the slots in the pipe removing all dirt and dust from both sides of the fabric, one side of the fabric being cleaned as it passes over the lower pipe and the other side of the fabric being cleaned as it passes over the upper pipe.

In commercial use it has been found that the edges of the slots 7 become worn and roughened so that the fabric in passing over these slots is frequently cut and destroyed. In order to obviate this difficulty I provide separate wear plates for the slots which-may be made of polishedsteel or the 1ike,the tubes 5 being generally merely iron pipe, and which may be readily removed from time to time as they wear;

In the embodiment illustrated in Figs. 3

and 4, this wear plate takes the form of a split tube 18 which has the edges of the slot 19 thereof turned back upon themselves as at 20. This tubular wear plate may be slipped over the nozzles 6 from the end or may be opened and sprung over the nozzles. The turned back portions 20 fit within the slot 6 and turn back upon the inner face 21 or" the slots so that a rounded edge is provided at the slotted opening in the nozzles and at the point over which the fabric passes thus providing a smooth surface over which the fabric may readily slip without danger of being destroyed or out.

In the form illustrated in Figs. and ('5, instead of making the wee r plate in. the form of a tubular men'iber I make the wear plate in the form of elongated plates 22 having the rounded and turned in portion 20 similar to the portion 20 on the tubular member 18. These wear plates may be secured on the nozzles in any desired manner as by counter sunk screws 23.

Having thus described my invention what I claim as new and desire to secure by letters Patent is:

1. In a device of the character described,

the oon'ibination with a tubular member having an elongated slot therein with ODPOSltG' angular edges, of removable means secured to said tubular member for guarding said edges, said means including portions extending over and conforming in shape to said member at opposite sides of said slot and rounded edge portions extending inwardly into said slot and embracing said edges to provide curved guards therefor to prevent damage to the material engaged.

2. In a device of the character described, the combination with a tubular member having an elongated, slot therein, of a removable longitudinally split sleeve adapted to slidably engage said member and to enclose the same, said sleeve having its longitudinal edges rounded and turned inwardly to embrace the edges or the slot in said tubular member whereby to provide removable, curved wear plates over the edges of said slot.

In Witness whereof I have hereunto subscribed my name in the presence of two witnesses.

EDWIN ROBINSON.
