Specification of Letters Patent.

Patented July`9, 1907.

Application filed October Z0, 1906. i Serial No. 339.846.

To all whoin 'it may concern:

Be it known that I, GEORGE M.`LANE, a citizen of the United States,lresiding at Lanoka, in the county of Ocean and State of New Jersey, have invented certain new and useful Improvementsin Poles, of which the following is a specification.

This invention has 'relation to a pole, staff, mast; spar, boom or the like7 and has for its object to provide a device of this lcharacter which may be readily extended or contracted and which when extended may be firmly secured against movement vin either direction, except by design and the application of properly directed force. i

The invention consists, essentially, of an extensible pole, spar or .the like comprising telescoping sections and novel means cooperating with the sections to secure them in a projected position; 'said securing means being of peculiar formation and arrangement.

The invention further -consists of novel means for attaching a flag, sail or the like* to the polevor boom..

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to behad to the following description` and accompanying drawings.

While the invention maybe adapted to different forms and conditions by changes in the'structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:-. l,

Fig. 2 is a sectional detail view showing Vthe joint-formed' between telescoping sections and the connection between the pole andthe agor like part attached thereto, Fig. 3 is a horizontal section on the line x-x of Fig. 2. Fig. 4 is ia detailw View showing the ends of adjacent sections when separated. Fig. 5 is a detail View showing the pole4 tele; scoped. Fig. 6 is a detail perspective view oi one of the couplings employed for connecting a flag, sail or the like to the pole, mast or boom. Fig. 7 is a horizontal section on the line yy of Fig. 1, showing the parts on a larger scale. l

Corresponding and like parts are referred to in the following description and indicated in all the viewsof the drawings by the same reference characters.`

The -pole, spar, boom or the like is composed of similarly formed sections 1 having'a telescopic` arrangement to admit of reducing its length when required by sliding the sections one within the other, after being released. One end of a section is provided in opposite sides with slots 2 in the lower edge of which are formed notches 3 to provide seats for receiving the interlocking extensions 4 bymea-ns of which the sections are held projected and in alinement. The fopposite end of a section is provided at opposite sides with openings 5 through which theinterlocking extensions 5 project. The interlocking extensions 4 form the horizontal arms or members of angle pieces 6 which are located within the extension and have pivotal connection therewith in any suitable andpconvenient way. The vertical arms or members 7 of the angle pieces noi-mally lie against the inner sides of the section and the ends remote from the extensions 4 are pivoted to lugs 8 projected from a ring or hoop 9 arranged within the section and secured thereto by rivets or in any substantial way. A spring 10 is interposed between the angle pieces 6 to hold' the extensions 4 projected, said spring being of the extensiblel coil type and having its ends encircling teats 11 extended inward from said angle pieces 6, thereby retaining the spring in proper position. When the sections are drawn apartv to the limit of their movement to bring the openings 5 of the one in register with the slots 2 of the other, the extensions 4 held repressed by the enveloping section, ily outward through slots 2 i and secure the sections against movement in either direction. When the interlocking extensions 4 enter the notches or seats 3, the sections are prevented from relative turning and are held in alinement.

-When it is required to telescope the sections so as to reduce the length of the pole,`boom, spar, or the like,

the outer ends of the extensions 4 are pressed upon to.

cause them` to clear the inner sides of the section having'the slots 2. 'When the section telescoping within said section is free to slideor move therein, as will be readily, understood, thefsections may be 'operated'.

either by hand or by mechanicalmeans according to.

the weight and construction' of the pole, spa-r oli-the like. l

When the pole or staff is used for supporting a flag,

"sail or lthe like, said poleisprovided in its length with longitudinal slots l2 to receive coupling pieces 13 attached to the ag 14 or like parts. AEach coupling piece 13 com'prises outer wings l5 and 16 and an intermediate neck 17. One of the Wings, as 15, is providedwith lopenings to receive -the stitching or like fastening approximately to the inner transverse'curvature of the pole or section thereof with which the coupling coplcrates. When attaching the Hag or like part' to the,

poleior staff, the coupling is turned to cause the wingy 1e to aline' with the not 12,- after which the andV wing is thrust'through the slot and permitted to make none- I separated.

" 2O avoid 'such extent, other slots 18 ape provided in the -40 19 to make positive engagement withthe openings 21 45 which Ione end offthe'spring. 22 bears, the oppositeend "I 55` yclaimed as newl quarter turn, thereby preventing its withdrawal. To uncouple the flag or like part, the coupling is 'turnedA to bring the wings 1 6 in line and register with the' slot 1'2 when it may be withdrawn therethrough. e When the pole or like part is not required for immediate use, it may be telescoped, in which condition the' interlocking extensions 4 are held repressed. by eny gaging with the inner walls of the section within which they are arr'angecl'rtol slide. If it he required un# couple any o f the sections they are turned to cause the interlocking extensions 4 to register with the' part of the section coming lbe'tween the slots 2, henceY upon drawing the sectionsapartthe interlocking` extensions 4 will pass by the 4slots 2 and enable the vsections to be It sometimes happens that upon turning a sectie too far, it will separate from the cooperating section when extending the pole and thereby cause in'convenience and delay at an inopportune moment. To

sides of the sections at the end having the slots 2, said slots 18,being`arranged ashort distance'from the planef of the slots 2 and opposite to the part of thesection 'between them, asindicated mostclearly in Fig.

'25 When it is required to separatel any of the sections, the

'member to be removedA is turned so as todirect the j interlocking extensions around the ends of the

slots

2 and 18, as will lbereadily understood. A,

When the pole, mast or the like is of heavy construction, itis preferred to provide'mechanical means for operating the sections both in extending andtelescoping the parts. For this purpose, a spur wheel 19 is provided and mounted in a swinging frame 20 which I v in lturn is supported at or near the upper end -of'the outer or lower section. The spurs, cogs or the like of.' the spur wheel 19 are adapted to enter openings 21V formed in a side of Athe sections and. constituting ay rack.

A spring 22 normally .exerts a pressure to swing the. frame 20 inward and cause the cogs of the spur wheel*l oi thefsectionssoihat upon turning the spurwheel, thevsections may be extended or withdrawn. A clamp f band 2 3(4 is f ittedto the upper portion fof the .outer or, lower section of the pole and has a projection 24 'against f .of'said spring engaging with a projection 25 at the?,r lower end ofthe frame 20. A detent pawl 26 coperating with the teeth 4or cogs of the spur Wheel 19 holds.v the latterin-an adjusted position and prevents down. ward displacement of the sections. Byfl'ravin'g thel frame 20`mounted so as to swing the spur wheel. 19 accommodates itself to the various sections, bothz wheny lengthening or shortening the pole or like part. f Having thus ydescribed the invention, what is '1. Afpole, boom,y spar or the like, comprising telescoping sections, one o f the sections having opposite openings in its sides, the coperating section having corresponding 'openings'.i its sides, angle pieces arranged within the in g openings of adjacent or coperatingsections when drawn outward to form positiveA interlocking means, and means forrnormally exerting pressure upon' said extensions.

2. In` combination, a sectional pole, boom, spar or the Alike adapted to have its sections telescope and provided at 'opposite points with corresponding openings, angle pieces :arranged within the inner section and having pivotal con nection therewith and having their relatively horizontal members arranged toproject through the registering openings of the coperating sections 'when extended; the vertlvcal or longitudinal members of the angle pieces adapted to llejagainst the inner side of their carrying section, and a springinterposed between said angle pieces to normally press them apart.A I

3. A sectional pole, boom, spar the likeadaptedl to l have its sections telescope, one of the sections having slots in opposite sidesand a notch in an edge of each slotforming a seat, and the cooperating section havin'g corresponding openings, and interlocking extensions arranged Within the inner vsection and normally pressed ,outward through' t `openings thereof to enter the slots of the cooperating sections when drawnoutward to hold them in -iixed position, said extensions adapted to enter the aforementioned seats to` prevent relative iturning o; the sections and .to hold` them in alinement when projected.

'4.A sectional pole, boom,y spar or the like adapted to have its sections telescope and provided with'correspondingopenings in theiil sides, a hoop or bandsecured within the inner section, angle pieces located within said section pivoted to said hook and having their horizontal members adapted to project through th-openings of. companion secand havingthe free ends' of their longitudinal members- 5. Ina device of the character set forth, thev combination f of two telescoping sections having corresponding openings in their sides,va hoop or band secured within the inner sec-- tion and having lugs, angle pieces having-the -free ends of theirlongitudinal members pivoted to said lugs and having their horizontal members adapted t'oextendthrough the' openings of the-sections when drawn apart, and a spring -I I interposed between the angle pieces and having connection therewith and serving to'norinally press -the same apart.

.' 6. In combination, a telescoping pole, a spur wheel adapted to .cooperate with the sections to admit of lengtheningor shortening the pole, and a movahle'supportjfor said .spur wheel.

7. In cpmbination,` a pole comprising' telescoping secltions, the scctionshavlng 'a rack at one side, a spur wheel for cooperating with the racks of the several sections to` .admit ,of lengthening and shortening the same, and, a Qswinging support for the spurl wheel secured to'a section ot'thepole. r

l8. In combination, an 'extensible pole' comprising telescrfpngvsections provided with racks, a spur wheel for cooperating with the racks of the sections to admit of lengthening or shortening the pole, a swinging support for said spur wheel, means for connecting said swinging sup' popt to a section of the pole, a spring normally exerting a force upon the swinging support to hold the spur wheel in engagement with th' racks of the respective sections, and va datent pawl for holding the sections extended against accidental downwardmovement. l
