roLisH'ING MACHINE.
Applicatign iiled May 12,
This invention relates to polishing machines, particularly those adapted for polish ing rods and tubes and similar elongated articles.
An object of ,the invention is to produce a polishing machine which will be rapid and elicient in operation.
Another object is to providev a polishing machine which will be compact and occupy little iioor space.
Another object is to provide 'a polishing machine at which two operators may worr simultaneously and which may be controlled by either operator. i
Another object is to provide a polishing machine in which a plurality of articles may be simultaneously polished.
Other objects will hereinafter appear.
rlhe invention will be better understood from a description of one practical embodiment thereof illustrated in the accompanying drawings, in which -0 Fig. 1 is a front elevation of a machine constructed to polish round bars or tubes.
Fig. 2 is a side elevation of the machine illustrated in Fig. 1. Y
The machine illustrated comprises a base 1 carrying at its top a flat bed 2, having wa s 3 in which bearing supports 4 may sli e transversely of the machine. The supports may be easily and quickly adjusted transversely of the machine by screws and hand wheels 5 and are normally adjusted to maintain a considerable tension on the polishing belts.
In the bearings at the top of these supports are mounted parallel shafts 6. At each end of each shaft a pulley 7 is positioned and the intermediate part lof one of the shafts carries a drive pulley 8. e
The mounting of the pulley shafts close together permits the use of short and relatively inexpensivebelts as well as making the machine compact. Moreover, there is comparatively little sag in the unsupported part of the belt, due to its short span, so that the tension of the belt may be relied on to provide pressure enough for polishing.
The operation of the device is as follows:
The operator steps on one pedal, which depresses both carriers and then inserts a pipe in corresponding notches 13 or 14 in each carrier so that its surface will be polished by the moving belts. After inserting the pipes the operator releases the pedal and the springs press the ipes against the polishing belts. As the elts move and polish the surface, the operator feeds the pipe through the machine. Simultaneously with this operation, an operator standing on the other side of the machine may be likewise polishing and feeding a pipe through another no .pair 'of notches in the carriers. When the pipes have been fed through the machine so far that the end which each operator holds to direct and feed the pipe becomes too short for convenience, the operators may exchange pipes and each then pulls the pipe received through the machine towards him, finishing the polishing operation. i
The carrier may be provided with differently sized openings as shown at 13 and 14, so that the machine may be used for different sizes of pipe, without change -of parts.
I claimv A polishing machine comprising two tensioned polishing belts passing around pairs of pulleys, the portionsv of the belts between movable, springs attached to said cradles moving the same together with the Work sup.
ported thereby upward, and a pair of pedals connected toaether by linkage, either pedal simultaneou ly moving said cradles downwardly, one pedal being accessible from each side of the machine.
In testimony whereof I hereunto airix my signature this 4th day of May, 1926.
EARL K.Y HOLMES.
