3 Claims.
This invention relates to a' portable handle and motor-equipped machine having especially constructed and arranged surfacing conditioning means for satisfactorily acting on painted platforms, boat decks and other surfaces in a manner to properly impact same to loosen paint, scale and rust and to thus pave the Way for ready removal thereof.
More specifically, the principal novelty is predicated upon an electric motor-driven rotor or drum, this characterized by a structural assemblage having circumferentially spaced rods revoluble through an orbital path, said rods having mounted thereon surface impacting elements and said elements having individual rotation on said rods to thus provide a sort of a planetary motion in which the elements move through the same orbital path as the rods but rotate on their own axes to produce the desired results.
In carrying out the principles of the invention,
I prefer to use impact elements resembling hexagonal nuts, the marginal surfaces, that is the interventing fiat and corner portions, providing the progressive and-successive surface pounding and scraping steps desired.
Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings:
Figure 1 is a side elevational view, partly in section, of a surface conditioning machine constructed in accordance with the principles'of the instant invention.
Figure 2 is a section taken on the plane of the line 2 2 of Figure 1.
Figure 3 is a front end elevation of the machine shown in Figure l.
Figure 4. is a perspective View showing one of the rods and a pair of the surface contacting, pounding and scrapping elements.
Referring now to the drawings, by distinguishing reference numerals, I touch briefly and broadly on the frame structure of the machine, this being denoted by the numeral 5 and being of any appropriate construction to accommodate the essential parts. It is provided on its under side adjacent the front with stationary wheels or rollers 6 on fixed brackets l. Swivelling rollers 8 are provided at the rear, the yoke portions of these having veritcal axles or spindles 8 which. extend up through projecting bearings it on the side members of the frame to provide the desired traction and swiveling action. It will be observed that a coiled spring h surrounds the stem '9 and is interposed between thebearings to allow a, yieldable actionat the I frame and roller or wheel assembly. The frame 1 also serves to support a suitable motor I 3 and handles M are provided on opposite sides, these having suitable hand-grips and being anchored in place in any appropriate manner as indicated at the points IS. The motor pulley [6 drives the belt I l which in turn is trainedover a pulley IS on the surf-ace conditioning drum structure l2. The drum is provided with an appropriate axle l9 journaled in bearings 20.
The drum structure is characterized by suitably constructed frame disks 2| these being longitudinally spaced at required intervals as shown in Figures 2 and 3. These disks in turn, are provided at marginally spaced points with relatively fixed or stationary rods 22. Or, to put it otherwise, the rods are anchored in the disk elements at circumferentially spaced points as brought out best in Figure l. The rods serve to accommodate the multiplicity of surface impacting and conditioning elements 23. Although these could be, in an emergency, in the form of stock nuts, they are preferably made of suitable stock and the central holes or hub-portion 24 are smooth. In fact, the diameter of the holes is proportioned so that the rod 22 coacts snugly therewith. Of course, the marginal edge portions of said elements can be six-sided or eightsided, as desired. I have found it practicable to use hexagonal surfaces.
The rotary cutter-head, if it may be called such, needs no sharpening and is driven a great deal slower than other types. As a general rule, five or six hundred turns per minute has been found sufficient. It has a scraping action coupled with a rotary pound and as the rotor turns around or revolves, the hexagonal or octagonal elements turn-on their own axes. This affords the aforementioned planetary action such as has been found to work satisfactorily until the corners, that is the sharp corners on the marginal edges of said impact elements are worn down and said elements become substantially ring-like or round. While it has been found that the head will not work on soft substances, it is substantially fool-proof on steel and once the cutter head has been adjusted it needs no further tampering. In practice, it has been found that it is sturdy power and impact and pounding and not speed, which does the work. Irregularities, in the deck or other surface are compensated for by the self-accommodating spring Wheel mounts at the rear of the frame. It has also been discovered that almost anyone, that is anyone without experience, can operate a machine of this type and do a satisfactory job. In use, it has been proved to clear rust and scale and paint quickly. Hand scraping devices, and other socalled motor-driven portable machines which have to be held against the surface, cause fatigue and require self-regulation of the depth of the cut made. In fact, there are many objections to types of machines with which I am familiar, and I have found that this one is simple. with out intricate parts, and that there is nothing to break or become easily thrown out of gear or order. The entire over-all structure is exceedingly simple and expedient and aptly fitted for the purposes intended.
The greatest differences are the shapes of the so-called surface conditioning elements, the reduction of wear between said elements and their rods by proper fitting coaction and that the structure is sufliciently self-contained and allinclusive in purposes and results to achieve the desired aims.
It i thought the persons skilled-in the art to which the invention relates will be able to obtain a clear understandingof the invention after considering the description in connection with the drawings. Therefore, a, more lengthy description is regarded as unnecessary.
Minor changes in the shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
I claim:
