Application December 3, 1945, Serial No. 632,474
This invention relates to flag-poles and the principle object of the invention is the provision of improvements in both construction and operation over the flagepole illustrated in my Patent No. 2,377,219, issued May 29, 1945, and also over my pending patent Serial No. 530,950, on Flag- Pole and Operating Means Therefor, iiled April 14, 1944, and issuedas Patent No. 2,440,500 on April 27, 1948.
One of the principal improvements shown in. this invention is improved flag operating means, a positive raising and lowering of the ag being accomplished by turning a crank in the proper direction, whereas, heretofore a' weight was used to pull the flag in one direction.
A further objectv of the invention is the provision of a hollow golden colored glass ball on the top of the nag-pole, the ball 'being in halves so that a pulley may be enclosed therein shielded from the Weather.
A still further object of the invention is the provision of means for enabling the thrust ball bearing, which permits the flag to ly in any direction with the wind, to be entirely invisible, the rotatable flag-pole extension continuing in adirect line of vision with the flag-pole.`
And a still further object of the invention is the provision of a sectional nag-pole which can be assembled' on the job, the joints being generally invisible and being tapered off at such a small angle thatthe pole appears to taper from bottom to topV in one continuous line.
Other and further objects will appear in the specifications and be speciiically pointed out in the appended claims, reference4 being had' tothe accompanying drawings exemplifying the invention, and in which:

Fig. 9 is a vertical sectional view of the improved thrust b'all bearing arrangement.
Fig. 10 illustrates the method of joining two sections of different diameter hollow pole sections together so as to simulate a continuously tapering pole.
Referring to the drawings in which like characters and numerals of reference refer to similar parts throughout the several views, the numeral II denotes the ground or other base on which the flag-pole I2 is set. At a convenient operating height on this pole is the flag operating section I3 which is attached intermediate the lower pole section I 2 and the upper pole section R4, this attachment being in any suitable manner such as by Welding at I5. A door I6, hinges not shown, is provided in the section I3 for inspection, etc. The flag I1 is operated by pulling the rope i8 (see Fig. 5'), from the flag operating section I3, through hole I9 in the hollow nag-pole extension 6I, the ag entering the hollow pole through said hole I9 when the flag is hauled down and vice versa when it is desired to fly the flag. The ends of the ropev I8 terminate at the middle inner edge of the flag I'I at the line 20, the resulting loop passing over the pulley 2l within hollow half ball sections 22 and 23 and down through the hollow interior of the pole I4 to the flag operating section I3.
The ag operating mechanism comprises a three armed spired 24 secured transversely to the opera-ting section I3 by screws 25 as illustrated, this spider being provided with a centrally disposed hole ZE through which the hollow yoke shaft 2'! extends and is free to revolve therein. This hollow shaft 2l is provided at its lower part with concentrically arranged serrations or teeth 28 while the upper part of the hollow shaft 2l is attached by means of set screw 20 to yoke 39. Between the serrations" 28 and yoke 30 are mounted the bevel friction wheels 3| and 32, these wheels being attached to each other (not shown) but being free to revolve about the hollow shaft 21. Another bevel friction wheel 33 frictionally contacts wheel 32 as illustrated in Figs. l and 2 and is normally free to rotate around the' perimeter of wheel 32 with hollow shaft 2l', the Wheel 3'3 being attached to shaft 34 by means of set screw 35, the shaft 34 passing through both extended arms of yoke 30. The shaft 34 has a sdu'are cross section in the middle portion thereof as illustrated in Figs. l and li, a reel 35 being free' to slide along this shaft, the extent oi this sliding movement being limited by the extending arms oi yoke 30. A collar 31 is attached to one 3 end of shaft 34 as illustrated and another collar 41 is attached by means of set screw 48 to hollow shaft 2'I as shown. Between two of the arms of spider 24 is a boss 33 through which extends a hole 39 communicating with vertical hole 25 in the spider. In line with hole 3Q is attached to section I3, as by welding, a boss 45 which is also provided with a hole through which shaft 4I is free to both slide longitudinally and revolve. The shaft 4| is preferably slightly enlarged at the pole end as illustrated in Figs. 1 and 3 so as to provide a convenient socket 42 for the reception of crank 43 and also to act as a shoulder for friction wheel 44 which is secured to shaft 4I by means of set screw 45, this wheel 44 being normally forced radially outwards together with shaft 4| by means of spring 45 which encircles shaft 4| and is compressively confined between the friction wheel 44 and boss 38. The shaft 4l has a point 43 on its inner end which point is designed to enter the space between any two adjoining serrations or teeth 28 but is normally held out of contact therewith by the compressive force of spring 46.
The operation of this mechanism is now as follows; assuming that it is desired to lower the flag from its flying position shown in Fig. 5, the crank 43 is inserted into square socket 42, and pushed inward so as to overcome compressive force of spring 45, this causing friction wheel 44 to contact friction wheel 3|, and simultaneously causing point 49 on end of shaft 4| to enter the space between those two serrations 28 in hollow yoke shaft 2'I which happen to be in place, thus preventing this yoke shaft from rotating, the
separates the two ropes to prevent entangling, L."
etc. It will be noted that the same number of rope turns always remain wound about the reel as, while rope leg I8 is winding on the reel, the portion IBA of this rope is unwinding an equal amount, this portion of the rope leading to pulley 52 which is tensioned downwards by means of spring 53, the swivel connection 54 enabling the pulley 52, hollow shaft 2'I, yoke 33, reel 36 and flag I'I to rotate unrestrictedly in either direction with Varying directions of the wind under normal conditions, that is, when the crank 43 is withdrawn from use. The lower end of spring 53 is attached to screw eye 55 which is secured to floor II and the pulley 52 is mounted in clevis 56. As crank 43 is turned to the right as aforesaid, the rope leg I8 winds up on reel 3S and pulls ag II downwards into hole I9 and down into the hollow interior of the flag-pole I4 a sufficient distance to house it from view and weather. The
crank 43 is then Withdrawn from socket 42 whereupon the spring 46 forces the parts to normal disengaged position. To bring the flag again into iiyng position, the crank is again inserted into the socket 42 and turned to the left, this causing the ag to be hauled out of the hollow interior of pole I4 into position illustrated in Fig. 5. The rope leg 50A extends from pulley 52 to reel 33. Only a single length of rope is preferably used, stretching and any unequalized mechanical operation of the rope being automatically adjusted by the resiliency of spring 53, a weight being substituted for the spring if desired. It will be apparent, from this arrangement, that a positive pull on the flag II is provided in either direction while permitting the flag to rotate with the wind under normal conditions without limitations. The rope legs I8 and 55 are always kept taut so that the inner edge of the flag remains close to the flag-pole, thus improving the flying appearance. The reel 36 moves transversely Ialong shaft 34 a limited distance according to the winding and unwinding of each respective rope leg I8A and 53A. The ends of the rope are preferably sewed to the inner edge of flag I'I, the rope leg 50 traversing pulley 2| housed within golden colored glass ball halves 22 and 23. A bolt 5l, which is designed to pass through holes 22A and 23A of the ball halves, secures these halves together being incidentally a shaft for pulley 2|. An annular depression 58 is formed in half 22 while an annular projection 59 is formed in half 23, the projection 59 fitting into the depression 58 so that a flush outer surface is obtained. A semi-circular hole BIJ is formed into each ball half which, when the halves are clamped together by bolt 5'I, form a single round hole through which one rope leg 5|) extends from pulley 2|, the other leg of rope extending into hollow extension flag-pole 5I through hole 62 which is also formed from two semi-circular holes in the two ball halves. A protruding shoulder 63 on each ball half extends into the top of flag-pole extension 6I a short distance as illustrated in order to secure the ball in place.
The flag-pole extension 6| is preferably constructed of thinner metal than flag-pole I4 and ends at the top edge of this pole, a small space 66 being left therebetween. A re-inforcing tube 64 is attached to the flag-pole extension 5I on the inside thereof as by welding or press fit, as illustrated in Fig. 9, this tube also having a hole 65 in register with hole I9 in the flag-pole extension. The tube 64 extends downward into the flag-pole I4 a short distance as shown in order to steady the flag-pole extension. The tube 64 however, is free to rotate with the flag-pole extension on a Vertical axis within the hollow nag-pole I4, there being an inwardly projecting flange 61 between the lower edge of which and the washer 68 -a number of balls 69 are housed. It will thus be apparent that the flag-pole extension 6| is rotatable within flag-pole I4 on a ball bearing mounting, the outer vertical faces of these poles being flush and yet permitting the ag I'I to be hauled therethrough. Gears would be substituted for the friction wheels on the larger sizes of agpoles.
In Fig. 10 is illustrated the method of forming the lower portion of each pole section, comprising the main xed pole, so that each section will snugly t into each adjoining section and remain in place without the use of any fastening means between the two sections, incidentally having the appearance of a single uniformly tapering pole. This construction also has the advantage of permitting the entire flag-pole to be conveniently shipped in sectional form from the factory to the erecting place and simply stuck together without the use of tools or experienced mechanics. The character I4B denotes -a lower pole section and I4A an adjoining upper pole section. To pipe section |4B is attached, a short distance above its lower end, a hollow cone frustrum II by means of welding (not illustrated), or by any other convenient means, this cone frustrum havlng its base of the sanie-v outside di-ameter as the lower pipe section and its. top.- of the samef out.- side diameter as the upper pipe section thev degree of inclination from the vertical being approximat'ely three degrees, it having been found byI experiment that it is impossible for the eye to discern the joint from a uniformly tapering pole. It. will thus be apparent that, when` erecting the pole, all th-at is necessary is to insert the lower end of each successive smaller pole section into the top open end of the. next larger pole section, the cone frustrum 1| forming a shoulder on which the upper pole section rests on the top edge of the lower pole section, while the downwardly projecting portion 'l2 of the upper pole :l
section provides lateral stability and keeps the sections in close alinement. Should it ever be desired to dismantle the flag-pole, all that is necessary is to remove the sections by lifting each upper pole section successively off each lower pole section. Should it be desired to securely attach the upper and lower pole sections together, this can be easily done by welding through holes 'ID'. The pole sections are compressively urged together by means of spring 53 through the medium of ropes I8 and 50 operating over pulleys 52 and 2|.
From the foregoing description, it will be apparent that I have perfected a method of forcibly pulling the flag into or out of the hollow flag-pole while permitting free and unlimited rotation of the flag in respect to the fixed pole, a means for providing a serviceable and everlastingly bright appearing ball on the top of the flag-pole which incidentally houses a pulley, a means for permitting ball bearing action between the flag-pole extension and the fixed flag-pole without altering the appearance of the sleek tapering pole, and a means for assembling a flag-pole from pipe sections of progressively decreasing diameters in such manner that the flag-pole will have the appearance of a uniformly tapered pole.
