IETHOD OF AND APPARATUS FOR CLEANING A ND CONSE RVING E0181 GABLES- Appllcation Med May 5, 1925. Serial No. 28,184.
To all whom it may concern:
Be it known that I, KARL Biionnn, a cltizen of Germany, residing at Brambauer, Germany, haveinvented certain new and useful Improvements in Methods of and Apaaratus for Cleaning and Conserving Hoist ables, of which the following is a specification.
. My invention relates to a method of, and 0 apparatus for, cleaning and conserving hoist cables, particularly cables used in mines. My novel method comprises the following successive stages which may be performed in a single continuous operation: cleaning the cable, drying it, applying a conserving preparation such as varnish to the cable, and drying said preparation.
Generally, hoist cables require a fresh coating of preparation within determined periods, for instance, eight weeks for new cables and four weeks for old ones, unless the conditions of operation, wet shafts, aeid mine water, etc., require a more frequent treatment of the cables.
The preparation is a plied by means of a piece of cloth or a brus but in this method those parts of the cable which are mostly exposed to failure, that is, the fine partitions of the profiled strands, are inaccessible to the preparation.
It is an object of my invention to overcome this drawback by injecting the said preparation into the finest crevices of the cable through suitable nozzles, and, preferably, drying and cleaning the cable before applying the preparation, and drying the preparation when it is on the cable, by hot air from similar nozzles.
With my novel method it is possible to treat a cable in about an hour as com ared with a duration of three or four days in the old method. Moreover, the treatment is very eflicient because the finest crevices of I the cable are thoroughly filled with the preparation and said preparatipn sticks to the cable very firmly as 1t is immediately dried.
In performing m method, compressed and, preferably, hig ly heated, air, is directed on the slowly moving cable through annular or other nozzles for a certain distance and the air so ejected cleans mechanically the surface and the crevices which are open toward the outside of the cable, and,
at the same time, dries and heats the cable.
The air nozzles or the set of air nozzles, as
the case may be, is followed by similar nozzles or a set of nozzles through which a mixers of heated preparation, varnish or the like, and preferably heated compressed air, is sprayed on the cable. The preparation readily adheres to the cable, is uniformly distributed over its surface and enters the smallest crevices between the wires. It is dried by means of a second set of air nozzles like the first which project cold or heated compressed air on the cable. so that the preparation adhering to the cable is dried and its stickiness removed. The nozzles or sets of nozzles are preferably arranged directly above the shaft openin or hi her up, as desired. Means should e PIOVldEd for permitting a slight lateral dis lacement of the ap aratus so that it may a apt itself to the w ipping of the cable.
In the drawings, I have illustrated devices in which my novel method may be performed.

.Fig. 2 is a sectional elevation, and
Fig. 3. is a plan view of a set of nozzles.
Fig. 4. is a-sectional plan view of a modilied nozzle arrangement. 7
Referring now to Fig. l, 1 is a pi e line conveying a fluid under pressure, for instance, compressed air. 2 is a branch pipe which conducts the air from the pipe line 1 to a heating coil 3' in a heater 3. A burner 4 may be provided at the base of the heater to which compressed air is supplied through an extension 4' of the pipe 2.. The end of the coil 3 is connected to a pipe 11 which opens into a tank 8 containing the preparation with which the cable is to be treated, varnish or the like. An extension 5 of the pipe 11 is fitted to a sort of injector 5' to which reparation from the tank -8 is supplied t rough a pipe 9. The delivery pipe 5 of the injector 5 is connected with t e spraying apparatus 6. A heating coil 10 to which steam is supplied from a header 10" through a pipe 10, may be provided in the tank but it will be understoodthat any other heatin means, for instance, an electric heater, may employed. A branch pipe 18 supplies heated an under pressure to the air spraying nozzles or sets.
In Fig. 1, only the central or preparation spraying nozzle 6 is shown. The complete 1 nozzle apparatus is illustrated in Figs. 2 and 3. It comprises two sets of air nozzles, 60 and 61, and the afore-mentioned set of preparation nozzles 6.
Each nozzle body is divided at its centre so as to, permit its being placed over the cable which is indicated at 13, and a packi strip 15 is inserted between the two halves which may be secured together by any suitable means such as screws, not shown.
Compressed air from the pipe 18 is supplied to each nozzle body 60 and 61 through pipes 20 and 20, respectively. These pipes connect with annular chambers 19, 19', respectively which are provided with upwardly directed lips 31, 32 in the lower body 61 and with downwardly directed lips 22 an 23 in the upper body 60. The central openilg of the body 60 is flared at the bottom at 1 The central body 6 is connected with the injector delivery pipe 5 by pipes 26, 26 which open into annular spaces 27, 27 at the top and bottom of the nozzle body. Hollow nuts 24 and 30 are screwed into both ends of the body 6 so that adjustable slots 28, 28' are formed through which the mixture of air and preparation is directed toward the cable 13.
The spraying apparatus is supported by bolts 37 and nuts 36 which are inserted in the eyes of flanges 35 at the several bodies. Obviously, any other means may be provided for connecting the bodies. The central body 6 is shown suspended on rollers 7 on a track 16 so that the apparatus is free to yield laterally. The pi e connections from the injector 9 and the branch 18 must be flexible to permit this. It will be understood that any one of the sets of nozzles may be so supported and that the resiliency may also be obtained by other means.
The operation of this apparatus is as fol-- lows: Air under pressure is heated in the coil 3' and supplied to the bodies 60 and 61 as described. The air flows in downward direction in the body 60, and in upward direction in the body 61. The cable is moving downwards. Any dirt, rust or other matter which the air in the body 60 detaches from the cable, is deflected by the flaring opening 17 at the bottom of the body and the conical top 25 of the nut 24 so that it cannot get into the spraying body 6. Here, the mixture of preparation and hot air is ejected in a downward direction by the slot 28, and in an upward direction by the slot 28. After the cable has been sprayed with pre aration in the body 6 it is dried in the body 61 where the air flows in counter current to the motion of the cable.
It will be understood that it is somewhat unconvenient to have to divide the entire apparatus including the nuts 24 and 30 every time it is to be used, and to reassembleconserving preparation, a pipe line it about the cable. This drawback is overcome by the apparatus shown in plan view and part section in Fig. 4.
Here, compressed air or a mixture of such air and preparation, is su plied to an annular i pe 40 at 41, 41. Ra ial nozzles 44 with per orations 45 at. their inner ends extend from the annular pipe 40 radially toward the centre where the cable 13 is moving. The ends of the pipe 40 do not meet but leave a space 43 through which the ap aratus may be placed over the cable 13 a ter one of the nozzles in the vicinity of the openin 43 has been turned aside. This nozzle is bent at 44' and, when it is in its normal position as shown in Fig. 4, the band is turned toward the cable with its perforations 45.
