APPARATUS FOR GRINDING. AND POLISHING TUBULAR ARTICLES, &o.

S-peccat'on of Letters Patent.

Patented Jan. 1o, 1911;

Application filed September 30, 1910. Serial No. 584,651.

To all whom 'it may concern:

Be it known that we, WILLIAM GURDEN HALSEY and JOHN Gunmen, citizens of the United States, and residents of Orange, in the county yof Essex and State -of New J ersey, have invented certain new and usefut Improvements in Apparatus for Grinding and Polishing Tubular Articles, &c., of which the following is a specification.

This inventionl relates to apparatus for polishing or cleaning tubes, pipes or rods, and the like, composed either of porcelain, metal, or other material, and has for .its object the provision of polishing means which are capable of adjustment within reasonable limits, so as to insure al uniform grinding, olishing, or cleaning ac- .tion, upon the articles treated, irrespective of their diameter,

and also to permit of the application of varying degrees of pressure upon the said articles which are subjected to -the grinding,pol`ishing, or cleaning action. Moreover, the apparatus may be sov constructed 'as toeperniit of the grinding, smoothing and buffing of articles, such as metallic rods, in a single, continuous operation, in the same apparatus, or the separate steps may be performed successively in different apparatus.

The invention isparticularly described` and set forth in the and the accompanying hich, 1 is a vertical section of the appathetube operated upon in following specification drawings forming a Figure ratus showing elevation; Fig.

said tubes in section within the apparatus; Eig. 3 is a longitudinal elevation of a combination apparatus for accomplishing the grinding, smoothing and bulling of pipes,

. ously; and Fig. 4 is a composite view showing the ydifferent types of friction elements which Imay be employed.

Referring to the drawings,fthe numerals 1, l, represent sectional brush-backs which are removably and adjustably mounted between end-plates 2, 2, being mounted in slots bristle tufts A, A,

2', 2. The'said `brush-backs are .secured thereto by nuts 3, threaded on to bolts 4 which project from the said brush-backs. Each of the brush-backs is provided with which are arranged to article, for example,

frictionally engage an tube' B (suitable for v5 which projects tending bristle tufts A,

4adapted to rotate within the journal 9 hav- 2 is a plan View, partially rods, etc. continu filtering apparatus). As shown the said individual brush-backs may be adjusted to conform to the diameter of the articles to be subjected 'to the grinding, polishing, or cleaning operation. Preferably a circular brush-block 1 is secured within the collar from the lower end-piece 2, the said c1rcular brush-block being removablysecured within the collar by means of a locking-screw a, and having upwardly eX- which serve to receive the lower end of an article suchas the tube B. This circular brush-block constitutes an elastic support for the article inserted in the apparatus, with the result that all risk or possibility of fracture of fragile articles, due to contact with the end-piece, is eliminated. A shaft or journal 6 is secured to the collar 5, preferably being integral therewith, and this is provided on its. outer end with a beveled-gear element 7 which is arranged to mesh with a co-acting beveled-gear 8 and to be rotated thereby in the manner well known. The said shaft is ing a' llanged upper end 9 and an annular elastic,vor other suitable washer, l0, which is j adapted to seal the sameA against the admission of liquid through said bearing into contact. with the shaft 6.

The reference letter C designates thc bottom of a sink, or other receptacle, in which the said shaft is mounted, the bearing 9 being secured thereto by' means of a gasket 11 and a nut 11, as shown.

A shell or drumD, which is adapted to fit in an annulargroove b in the bottom C' of the receptacle, serves to revent the centrifugal ejection of liquid: uring the rotation of the brush element, and consequently results inthe liquid X, which only partially fills the said shell when the apparatus is at rest, serving to completely lill the same during rotat-'on thereof, owin to its inability to escape horizontally an vertical rise of the same until it attains the upper edge of the shell.

E designates a vThe reference numeral or the like,

holder, such as a pair'of tongues,

for gripping the tube B during the insertion 105 the consequent uniform and whether the AULO ,friction element consists of bristles of wire order to retain t e tension of said springs at any desired degree adjusting screws y', y

are threaded into the said flanges 2 2, the same extending` therethrough and contacting with the saidl leaf springs y, y, whereby-the slightest inward movement of the screws will increase thew tension of said springs in the ,manner well'known. Itis evident that when the adjusting nuts Bare tightened, the action of the springs .will be rendered inoperative,` and when employing bristles for the friction element, such as hog-bristles or wire bristles, the action of the springs is usually unnecessary,` j However, when employing carborundum, emery, and like friction elements, the said nutsl 3 are loosened in order that the action of the springs will not be destroyed, as would be the case were the nuts tightened as aforesaid.

In order` that each friction element may be accurately adjusted to exactly the same relative position with respect to the article treated as is an adjoining friction element,

.the marginal. portions of each of the slots 2 are calibrated as designated by the reference letter Z, and the outer ends of the bolts 4, as`

shown' are scored in. order to provide an indicator and to enable one to accurately ad- I just the 'said bolts along the said slots.

ln Figl is illustrated a form of apparatas sultable vfor the treatment of piping,

rods, etc., in a continuous manner wit-hout removal fromthe apparatus. rl`his consists of a sectional rotary grinding member 12 which corresponds with the sectional brushback 1 except that the circular end-piece 1 is dispensed with, and in lieu of bristles tufts the friction element consists of emery or carborundum secured in any suitable mannerrtothe sectional backs of the grinding member. lA smoothing member 13', which corresponds with, and is secured toa common hollow shaft with said Grinding member, is provided with ,an elastlc friction element, sueltas wire bristles of fine piano wire brass wire, or the like, land a polishing member 1*, alsosecured to a common shaft with the .other two members, corres nds with the aforesaid member except t at the friction element 1s of soft material such as ,felt or cotton, or some such 'material capable kof a pulley 14 secured to said hollow shaft 12,

and servesto rotate the respectivegrindnig, smoothing,

and polishing member si-l multaneously, and thereby an article, such as a tube B, which is supported upon travelers 15, 15, can be successively ground or reduced, smoothed and linelyvpolished without Iremoval from thev apparatus'.

In Fig-L is illustrated a fragmentary composite View ol the different;v friction elements in elevation, in order to indicate the various elements which may be employed in theapparatus for carrying out the operation in a continuous manner. The reference numeral 1 designates the brush-back shown in Fig. l, which carries tufts of hog-bristles A, whereas the number 1 designates a corresponding 1brush-lnick which is -provided with an emery or carborundum grinding element or shoe. A2. Similarly the reference numeral l: represents a brush-back carrying wire bristles A suitable for smoothing a tube after the preliminary grinding treatment, whereas the brush-back l" which carries a felt bulling element A serves for thel purpose of`completing the iinal polishing of tubing o'r the like. j

The operation of cleaning porcelain tubes, such for example, -asthe unglazed porcelain tubes used for the so-called Pasteur filters, as distinguished from the continuous treatment. of tubes above described, can be conveniently and economically performed in this apparatus with a minimum risk of breakage and a minimum amount of erosion consistent with perfect cleansing. The y0peration is easily performedby me'rely setto dra-w 4the tube inwardly when once-the same is inserted in between the uppermost bristles, provided the same are adjusted so that the aperture between the ends of the respective bristles of the opposing brush-backs is a trifle less than the cross-section of said tube, preferably about of an inch less. This automatic drawing in of the tube can of course be rendered more positive or pronounced if the bristle tufts are so arranged that the path from one bristle tuft to the corresponding tufts of4 each individual brush-back is substantially spiral, in which event it is apparent that the rotation ofthe support in one direction` will draw the tube inwardly and when drawn i'n the opposite dilect-ion will tend to eject thesame, provided of course lthe tube ybe held against rotation, by the tongs or other means'with which it is gripped, while inserting or With-- drawing the same.

Having thus described our invention what We claim and desire to secure by Unitedl to each of said supports, and each member being disposed intermediate said supports and radially adjustable with respect to the centers of each of, said supports, said members being disposed around but distant from the centers of said supports, and each of said members bemg provldcd with marginal friction elements which extend alone' substantially the entire length thereot and which project inwardly from thelrrespec- 4tive inner faces, whereby a central'aperture is formed suitable for -the reception of an article to be polished or ground, and Ineans for rotating said supports simultaneously.

2. The combinationconsisting of a plurality of spaced supports, a plurality of elastically mounted individual members secured --at opposite ends to each of said supports,

and each member being disposed intermediate said supports and radially adjustable with respect to the centers of cach ot' said sup-ports, said members being disposed around but distant from tliecenters of said supports, and each of said members being provided with marginal friction elements 3o which extend along substantially the entiro 'lengththereof and which project inwardly from their respective inner faces, whereby a central aperture is formed suitable for the reception of an article to be polishcdfor ground, and means for rotating said supports simultaneously.
