WITNESSES: I /f%%%/ ZOMW # 4 A TTORNEY Patented Oct. 1, 1929 CHARLES E. MORRIS, or LEAVENWORTH, KANSAS CEfiTERPOLE AND SUPPORT THEREFOR Application filed July 26,

My invention relates to improvements in center poles and supports therefor. It relatesparticularly to center pole structures adapted for use with carousels, and which are adapted to be disassembled and moved from place to place. I

One-of the objects of my invention is to provide a novel center pole and support therefor, which can easily and quickly be set up or taken down, which is held together simply by the interlocking of the parts thereof, which eliminates screwsand bolts, which is strong, durable, not liable to get out of order, and which is simple and is cheap to manufacture. i

' A further object of my invention is the provision of a novel means for releasably locking together the different structure. I

Another object of my invention is to provide a novel means for integrally fastening parts of the a ring on a bar without having the welding or other fastening material used get uponthe exterior of the ring so as to destroy the regular contour of the periphery of the ring. My invention provides further novel means for releasably interlocking the pole to beams which support it.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention, f a

view through the pole and the inner ends of the beams, taken on the line 6'6 of Fig. 7.. Fig. 7 is a central vertical sectional View of the parts shown in Fig. 6, that is, the low-- er endof the pole and the inner supporting beams.

Similar reference characters designate similar parts in the different views ends of the l designates atubular center pole adapted tending lip 5 adapted to be extended up- 3 wardly into the lower end ofthepole I and to engage the inner periphery thereof,.whereby the beam is. held from outward longitudinal movement, and by which the. lower end of the pole is supported: The projections 3' hold the beams l and pole l from relative vertical movement. I In assembling the pole and beams, the lips 5 are first inserted into the lower end of the, pipe, and the, beams then swung upwardly at their outer'ends until the projections 3 enter the holes 2. Bracing means is then; employed to hold the outer ends of the beams- 4 from moving downwardly.

.Such. bracing means comprises, preferably the following described parts. I V

Mounted on the pole. 1, and preferably rigidly fastened thereto, is a sleeve 6, which is provided with a plurality of radiallylo cated upwardly and outwardly inclined, and preferably arcuate grooves 7, Fig. 2. The pole 1 is disposed so that the centers of the grooves 7 are respectively in the same vertical radial planesas the corresponding centers of similarly disposed arcuate grooves 8, pro' vided one on the upper side of each beam 4 adjacent to the outer end thereof. a Bracing bars 9 are each provided ateach end with anannular peripheral flange 10. The flanges 10 on the upper ends of the bars 9 are respectively fitted in the grooves 7 in the sleeve 6, and the flanges 10 at the lower ends of the bars 9 are respectively removably fitted in. the grooves 8 in the beams 4. The bars 9 may be placed into the grooves 7 and 8 from the outer side and the grooved portions of the sleeve 6 and beams 4 will hold the bars lowing described parts.

The pole 1 intermediate of the holes 2 and the sleeve 6 has a plurality of upwardly facing' arcuate grooves 12, Fig. '3, whose centers are located in the same vertical radial planes respectively as the bars 9. Each bar 9 is pro,- vided on its inner side in the horizontal plane ofthe grooves 12 with an upwardly facing arcuate groovell, s

Transverse horizontal bracing bars 13 are provided at their ends with peripheral flanges 14, which on one set of ends of the bars 13 are, respectively mounted in the grooves 12 in the pole'l. 'The other ends of the bars 13. have their flanges 14 respectively mounted in the grooves 11 in the bracing bars 9. The, grooved portions 11 of the bars 9 and the groovedportio-ns 12 of the pole 1 .hold

the bars 13 from endwise movement and from movement in any direction excepting 7 upwardly. Thebars 9: are thus held from outward lateral movement until the bars 13 have been lifted out ofthegrooves 11 and 12.

The flanges 10 on the bars 9, and the flanges 14 .on the bars 13 are preferably made as follows. A ring 14, Fig. 4 is fitted on the end off-a tubular bar, as 9, Fig. 4, and is welded thereto by, making the weld at the inner ends of radial holes 15 with which the ring is provided. In so welding at the inner ends of the holes, the weldingor fused material does notdeface and make irregular the outer ends and outer periphery of the rin ing occurs at the inner periphery of the ring spaced from the ends thereof. The flange14 thus form'ed may be neatly fitted in amaw chined groove 7 or 8 provided therefor in thesleeve of and in each beam 4. The above description also applies with the same effect to the making of the flanges 14 on the bars 13. Rings provided with radial holes are fitted on the bars 13 and then welded thereto in the holes of the rings.

In assembling the pole and other parts, the pole 1 may be disposed in a slightly slanting position fromthe' horizontal, and the lips 5 of two opposite beams 4 are slipped into the lower end of'the pole and the bea1ns 4 are 2, as the weldswung upwardly until the projections 3 thereof enter the adjacent holes 2 in the pole.

The brace bars 9 are then mounted in the sleeve grooves 7 and the grooves 8 in the two beams 4. The transverse brace bars 13 arethen fitted in the grooves 11 of the bars 9 and the grooves 12 in thepole 1. The next beam 4 is then fastened in like manner to the upper side of the pole 1, and is held in position by the insertion of its brace bar 9, the latter being secured by its transverse brace bar 13. It will be noted that each of the

grooves

8 and 12 has a distance between its ends, as measured diametrically of the adjacent brace bar, not less than the diameter of the flange located therein. By means of this construction, the

bars

9 and 13 may be inserted into or removed laterally, without endwise movement, from the grooves containing them, thereby making their insertion or removal independent of pole 1 or beams 4, and providing a very simple and quickly assembled or disassembled structure.

The pole 1, with the inserted beams 4, are then tilted so that the pole 1 is substantially upright, or enough past the vertical to enable the lip 5 of the last beam 4 to be inserted into the lower end of the pole, after which the last named beam is swung upwardly until its projection 3 enters the adjacent hole 2 in the pole 1. The brace bars 9 and 13 of the last inserted beam are then positioned in their operative positions, whereby the pole is securely anchored to the beams 4. The beams 4 and pole 1 may then be adjusted to a position in which the pole will be vertical and the beams 4 horizontal. i

To disassemble the structure,the operation above described is reversed, the brace bars 13 being first removed to permit the removal of the brace bars9. By means of the interlocking means shown and described, connecting the pole 1 with the beams 4, and braces 9 and 13, the parts are enabled to be quickly, assembled and held together without any accessory means, such as bolts and nuts.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.
