Description

0. 0. BROWN Nov. 2, 1965 SCALING DEVICE FOR CYLINDRIGAL OBJECTS AND THE LIKE Filed March 6, 1964 INVENTOR.
Beau/ FIG. 5.
United States Patent 3,214,824 SCALING DEVICE FOR CYLINDRICAL OBJECTS AND T HE LIKE Otho 0. Brown, Fort Screven, Ga. (Amelia Island LAS, Fernandina Beach, Fla.) Filed Mar. 6, 1964, Ser. No. 349,814 4 Claims. (Cl. 29-81) This invention relates to the general field of manuallyoperable tools and, more specifically, the instant invention pertains to the provision of means for removing scales, rust, incrustations, paint, varnish and similar undesirable debris which normally accumulates on exposed substantially cylindrical articles.
One of the primary objects of this invention is to provide a manually-operable tool of a flexible link type which is adapted for wrapping about a substantially cylindrical article and so manipulated as to cause the wrapped convolutions thereof to frictionally engage the cylindrical article to remove incrustations on the exterior side thereof as the tool is moved axially of the cylindrical article.
Another object of this invention is to provide a manually-operable tool of the flexible type which may be readily Wrapped about substantially cylindrical objects having undesirable accumulations of debris on the exterior side thereof, the tool including a plurality of knurled beads or abrasive beads disposed in spaced relation relative to one another.
A still further object of this invention is to provide a tool of the type generally referred to supra, which may be readily applied to tubes, pipes, and other substantially cylindrical objects disposed in locations wherein it is substantially impossible to employ a chipping hammer, scraper, or wire brush.
This invention contemplates, as a still further object thereof, the provision of a flexible chain-type manuallyoperable tool for cleaning the exterior sides of cylindrical and similar objects without chipping or denting the object as the cleaning operation is carried out.
Other and further objects and advantages of the instant invention will become more apparent from a consideration of the following specification when read in conjunction with the annexed drawing, in which:
FIGURE 1 is a top plan view of a scaling device or tool for cleaning the exterior surfaces of cylindrical or analogous objects and constructed in accordance with this invention;
FIGURE 2 is an enlarged detail cross-sectional view illustrating one mode of connection between adjacent scaling elements;
FIGURE 3 is illustrative of the mode of application of the scaling device or tool shown in FIGURE 1, FIG- URE 3 illustrating the device or tool as removing external debris from the outer side of a substantially cylindrical article;
FIGURE 4 is an enlarged detail side elevational view, partly in cross-section and illustrating another or alternate method of tool assembly; and
FIGURE 5 illustrates another embodiment of this invention.
Referring now more particularly to the drawing, reference numeral designates, in general, a scaling device or tool constructed in accordance with the teachings of this invention. As is shown in FIGURES 1 to 3, inclusive, the scaling device or tool comprises a pair of remotely-disposed substantially hollow triangular handles 12 of identical construction, each of which includes an elongated hand-gripping horizontally-extending base member 14 from the opposed ends of which rise converging sidewalls 16, 18 which merge in an apex end 20. The apex ends 20 each has a substantially hollow pocket "ice 22 formed therein substantially equal to the diameter of a substantially hollow spherical knurled sphere 24.
As is seen in FIGURES l, 2 and 3, a plurality of the substantially hollow externally-knurled spheres 24 are provided, and each adjacent pair of the spheres 24 are connected through links 25 that extend through diametrically-opposed conical openings 26 formed in the spheres 24 and which terminate at their opposed ends in substantially enlarged heads 27. The combination of the spheres 24 and the links 25 form a flexible chain 28. The connection between the links 25 and the spheres 24 is such as to permit each of the spheres 24 to rotate about the longitudinal axis of each link 25 associated therewith, the rotation of the spheres being accomplished independently of one another. Since the openings 26 are substantially conically-shaped, a certain swivel action is permitted between the spheres 24 about their respective connecting links 25 in order to lend flexibility to the chain 28.
As is clearly seen in FIGURE 1, the remotely-disposed ones of the spheres 24 are disposed within the pockets 22, and the handles 12 at the apex end 20 thereof are slotted as at 40 in order to permit the passage therethrough of those links 25 which connect the remotelydisposed spheres 24 with the next adjacent ones thereof. This type of assembly permits the tool or device 10 to be quickly and easily connected with the handles 12 and also serves to effect a quick detachment of the handles 12 from the chain 28 when the tool 10 is no longer required for use. This also enables the operator to store the chain 28 and the handles 12 in a compact manner so as to occupy a minimum amount of space.
In use, the chain 28 is wrapped about a cylindrical object 42 such as is shown in FIGURE 3, the wrapping including about one and one-half convolutions of the chain 28. In FIGURE 3 it is seen that the leading portion of the chain 23 is disposed at a substantially acute angle relative to the longitudinal axis of the object 42, and that the trailing end of the chain 28 is disposed substantially at right angles to the longitudinal axis of the object 42. The operator now grasps the base members 14 of the handles 12 and exerts reciprocatory movement of the chain 28 as is indicated by the arrows in FIGURE 3. Since the leading end of the chain 28 is disposed at an acute angle relative to the longitudinal axis of the object 42, the chain 28 will wrap and walk or otherwise move longitudinally of the object 42 to remove dust, dirt, paint, and/or other incrustations 44 adhering to the external surface thereof and thereby leaving the external surface of the object 42 in a clean condition. In using a cleaning tool of this construction, there is no possibility of denting or puncturing hollow pipe or other similar articles, such as is always possible when using chipping tools, and additionally, the tool 10 permits the cleaning of the entire cylindrical surface of the object 42 where wire brushes and other similar articles cannot be successfully employed. Again, this tool 10 possesses extreme utility in the cleaning of workpieces being turned in a lathe, for example.
FIGURE 4 illustrates another embodiment of this invention quite similar to that illustrated in FIGURES l to 3, inclusive. In this second embodiment of the invention, a plurality of hollow spheres 50 are provided, the hollow spheres 50 being coated with an abrasive 52. A plurality of spheres 50 are shown as being strung on a flexible cable or strand 54 with each adjacent ones of the spheres 50 being spaced from one another by spacer collars 56 which are also strung on a cable or strand 50 between each adjacent pair of the spheres 50. In all other respects, the two embodiments of this invention are identical.
In FIGURE 5 a further modification of the instant invention is illustrated. As is seen therein, this is seen to comprise a plurality of solid spheres or bearings 60 having a knurled outer surface 62 or, optionally, the exterior surface of the spheres or bearings 60 may be abrasive coated as at 64. Each of the spheres or bearings 60 is formed with an elongated axially-extending bore or passage 66 through which is threaded a length of flexible cable 68, and also strung upon the cable 68 are a plurality of elongated substantially cylindrical spacer collars 70 which are disposed between each adjacent pair of spheres or bearings 60. In all other respects, this embodiment of the invention is identical to that embodiment shown in FIGURE 4.
Having described and illustrated two embodiments of this invention, it will be understood that the same are oifered merely by way of example, and that the scope of this invention is to be limited only by the appended claims.
