HENRY A. HOFFMAN, OF BROOKLYN, NEW YORK.
Specification of Letters Patent. Patented Sept. 30, 1919.
, Application filed June 26, 1918. Serial No. 241,906.
I To all whom it may concern:
Be it known that I, HENRY A. HOFFMAN, a citizen of the United States, residing at the city of New York, borough of Brooklyn, Kings county, in the State of New York, have invented certain new and useful Improvements in Flagpoles, of which the fol lowing is a full, clear, and exact specification.
This invention relates to improvements in flag poles and has for its object to provide a pole which i so constructed as to permit of a flag being quickly and easily attached thereto, or detached therefrom.
Further, said invention has for its object to provide a flag pole of this type which is simple in its construction, durable and efiicient in use, and inexpensive to manufacture,
Further, said invention has for its object to provide a flag pole of this type with means for securely holding the flag in position throughout its entire width.
Further, said invention has for its object to provide a flag pole oft-this type having its upper portion split to form a plurality of longitudinally-extending members, and means to hold said members together at their upper ends, and intermediate their ends.
Other objects will in part be obvious and .in part be pointed out hereinafter.
To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combina tion, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.
In the accompanying drawing forming part of this specification, wherein like numerals of reference indicate like parts.
Figure 1 is a side elevation of a flag pole constructed according to and embodying my said invention, with a flag attached thereto, parts of the pole being broken away;
Fig. 2 is a sectional View taken on the line 22 of: Fig. 1;
Fig. 3 is a detail sectional view showing, a slightly modified form of construction, and
Fig. 4 is a perspective view of a modified form of clamping member.
Referring to the drawing 10 designates a pole of any desired length and cross-section, and formed of any suitable material. The upper end of the pole 10 is split longi-- tudinally, throughout any desired portion hold the segmental members together with the edge of the flag firmly clamped intermediate the same, and to protect the ends of the members from injury.
At one side of the pole 10, the adjacent segmental members 11, 11, are provided with parallel grooves 14, 14 in their outer surfaces e tending longitudinally of the pole 10, having their lower ends terminating below the lower ends of the segmental members 11, 11, and their upper ends preferably I terminating below the upper end of the pole 10. If desired, the grooves may taper, in deptlnfrom their lower to their upper ends, as indicated at-l4, in Fig. 3.
15 indicates a resilient clamping member which partially embraces the pole 10 and is provided with inwardly extending end portions 16, 16 slidingly engaging the grooves 14, 14, whereby the clamping member 15 may be slid along the pole longitudinally thereof.
In use, when it i desired to attach a flag 17 to thepole, the clamping member 15 is slid downwardly into its lowermost position, with the end portions 16, 16 thereof engagingthe lower ends of the grooves 14, 14, and the cap 13 is removed by unscrewing it from the threaded upper ends of the segmental members 11, 11, of the pole 10. The segmental membersll, 11, are then sprung apart sufliciently to permit the inner or rear edge of the flag17 to be inserted between the two segmental members 11, 11, in which thegrooves 14, 14,.are formed. The rear edgeof the flag17 is preferably so positioned as to engage both of the inner surfaces of one of the segmental members, 11,
as; shown in Fig.2,in order toinsure that the flag 17 will be held securely in place throughout its entire width. After the flag 17 has been thuspositioned upon the pole 10, the cap 13 is screwed in place upon the upper ends of segmental members 11, 11, thereby holding them together. The clamping member 15 is slid upwardly along the grooves 14, 14, to a position intermediate the ends of the segmental members 11, 11, in order to insure that they will be firmly held together throughout their entire length thereby effectually preventing the flag 1'1 without, depart ng; from thesp1r1t of the from inadvertently becoming detached from the pole 10.
The s 17 y: h emise-from the pole, when desired,by simply' removing the cap 13 and sliding the clamping rnembenlii downwardly into engagement with the lower whet-the reensthu pe i the emental members 11, 11, to be sprung apart sufliciently to permit the withdrawal ofthe' rear, edge of the flag 17 from itsposition between the segmental members '111, 1 1.
'In Fig 4 there is shown a modified' form of clamping member comprising a pair of arc-'shaped'members18 1 8 having-inwardlyextending groove-engaging portions 19,, 19
at" their front ends, andihaving perforated ears 20, 20- at their. rear ends to receive a bolt 21' carrying a nut22, to hold themeinbers. in assembledposition. This form of lamp n m m r pa ti a ly adapte "to be used'in connection with large poles cargl g flags.
While but oneiclamping member is shown, it will of course be understood that two or more. such members may beused, if desired,
invention. The use of more than'one clampmg member would'be desirable, for example,
' incase the flag, which isto be attached to the pole, is alai'geone, It will lsobe und 'oed h t he gr e 4s chh ay eeX- tended to the upper end ofthe poleiif desired; 7 if a."
