METALBASE FOR 'rnuen'aronn'sfi Application filed January et, 1927. SerialNo. 158 ,96O ,1.

: This invention relates to protecting-and supportingfbases or repair elements for-poles carrying ele'ctric transm ssion W1res. f '7 of. the pole.

Telephone, telegraph, and electric trans mission wires are usually carried .on' lround poles set in holes in the ground. Thesepoles are subject to rapid decaywbecauseof their .be'ingkeptina semi-inoistycondition by their contact-:with the soil. vThis decay occurs from lito 2 feet below the groundline,-the pole both above and below this zone of decay .abeing-reasonably durable, andrepairsare usually made either by building a reinforced concrete base around: the pole to span the decayed. portion or more commonly by wiring or bolting the pole to a timber post or- .stub setdeep intothe ground at thebase neediof repairs or replacement caused by the decay at the base of the poles and which will also furnish a cheap and substantially permanent base for new I poles. Y Y Another object of the invention is the provision of a device] for not only preventing Y decay ofthe basesof new telephoneand telegraph poles by maintaining the timber} part of the poles above ground but for protecting both" newand old poles against destruction from grass'andbrush fires by a metal covering of sightly appearance which extends above the Y ground, a suiiicient distance for thep rpo Y Q 1 A further objeet of the invention isthe provision of supporting and, protecting metal coverings for electric transmission line poles vwhich may be readily'driven into position thus eliminating thecases of the usual unsightly and expensive concrete bases em- Y ployed in supporting and protecting. the

Y K decayed bases of poles.

1 The invention consists of a cylindrical metalsleeve which is fitted tightly around the sound part of the, pole abovethe ground and extended; a sufiicient distance into the ground to give proper; support. In the case Y the sleeve also fits tightly aroundthe sound part of the-poleand below Y thedecayed part'.' In the caseot a. new. pole, the ,sleeve is fittedtightly aroundthe basecf "the .pole which is keptjabovethe j ground line, and the cylindrical, sleeve 7 is extended the proper distance into the ground lLOQgiVBjI the necessarysupport; I v c I The sleeve COHSISlJS of Y a metal tube or eylinder of c rcular contour made n' tvvo or Y more sections lO and 1 1 bysplitting on; a plane'passing through its longitudinal'cention of a cylinder of approximatelyjthe same diameter as the pole it is: intended to fit and The parts of the sleeve may either be made in halves with two forming a complete cylinderor they-may. be

made many number desired, withjeach'pait rolled to the diameter of the completed cylinder. 1 1

The edges 13 of-the rolled sheets are connected bya locking device consisting of a,T

sectionor lock frame 14; otthe same length:

Jterfline; g'Ihe-Qsleeves,are made of corru- Y gatedmetalsrolled or pressed to form a p'or- I with the corrugations l2parallel to the cenv ter otthe cylinder.

as the sleeve with 2 L sections or lock bars of the same length. Each wing 16 of the top of the T is formed to fit the inside of one of the corrugations 12 of the sleeve, and one leg 17 of each 'L is formed to the outside of one of these corrugations, while the other leg 18 of the L is-made to fit the straight leg the parts of the sleeves to the lock frame and 'erly' fitted, the corrugations stretched jand' sol'ne'what bedded due to the foi' eingofthe tightly fitting sleeve through the frame, to each other, but permitting longitudinal motion of the sections with respect to the lock joint or each other.

In applying the device to an old pole already in'theground, two or more sections are selected of such size that when secured together by the lock joint, the completed sleeve wilhfit'tightly around the pole. The sections are held against the pole with the lock frames place engaging with the corruga-' tions of the sleeve. The lock bars'are then inserted in thetop of the lock frame-as -shown in Fig. 3. They are then driven downas shown in Fig. 4,1'With their ends flush with the top and bottom of the sleeve. Thesleeve' is then either driven or "j acked "d'ownfaround the-base of the-pole 20 to the proper 'posit'ion as shownin Fig. 5, with the tops 21 of the sections 10 and 11' projecting above the ground.

"In this position, ifthe sleeve has been propwill be slightly in' the "pole down over theincr'easing diameter of "the 'tapered "pole. This will provide an elastic 'eleme'nt to 'take'c'are of the expansion and co'ntraction'of the sleeve from. temperature andof' the pole from moisture. p

' In using the device in connection with new poles, one orinoresections of the sleeve, 'formingftogether not'more than half a com ple'te sleeve, are driven a short distance into the'ground, The pole is then erected and held against'the"'driven sections of the sleeve. "The remaining'sections of the sleeve are then placed around'the pole and secured to the driveirpartby the lock joints. The newly placed sections are then driven to {the same position as the first driven sections, and

the operation [is completed by successive alternate dr'ivingof the sections of the sleeve "to th'eiriprop'er'depth.

The substitution of the driving of metal sections-forthe ordinary process of digging deep holes and refilling them is a great savround. 7 The'm'etal'base is neat and attractive in appearance as compared with the repairing of old poles by any other method-and especially by the usual process of stubbing.

The cost of the metal base in place is less than the cost of the extra length of a new pole without the metal base and the labor of digging and setting, and is less than the cost of the labor and material for concrete bases or for stubbing on old poles.

The metal base can be protected bygalthe sleeve being firmly joinedtogether in'ia circumferential direction but having free movement parallel to the axis of the cylinder along a joint made of a combination of'a T shaped bar with two L shaped barswhich together form the joint, thetop ofthe-T being corrugated tofit interior-ly with the corrugations of the sleeves, the lego f the'T passing between the parallel edgesof thesections'of the sleeveand having a cross at'its exterior and bearing against the exterior ends of the legs of the two L barsyone'leg of each of which is corrugated to*fit"the exterior corrugation of the sleeve, an'dthe locking being effected by the clamping offlthe' corrugations of the sleeves between" the conforming corrugations of the 1nter1orT"bars and the exterior l. bars.

2. A base for fixing timber -poles-in"the ground comprising a metal sleeve formed "of a plurality of sections corrugated lengthwise, and means for locking the adjacent edges of the section together, 'said locking means including'a T rod having: corrugated flanges engaging the corrugations of the sections and lock bars forwedging' the T bar to the "edges of the section.

A base for fixing timber poles 'in'the ground comprising a metal sleeve; formed of a plurality of sections corrugated lengthwise, and means forlocking the"'adj'acent edges of the section together, said locking means including a "l" rod having corrugated flanges engaging the corrugations of the sections and lock bars having corrugated flanges or wings engaging the"c'orr'ugated portions of the sections, said bars adapted to wedge the T barsto the sections.

4. A base 'for fixing timber poles in the ground comprising a metal sleeve formed of p I p I a plurality of sectionscorrugat'ed lengthing-in labor,,espec1ally in wet or caving wise, and means for locking the adjacent edges of the section togethe r,'*said locking flanges engaging the corrugations of the sections and lock bars of L shape construction having straight portions engaging the-T bars and corrugated wings or fianges'seated on' the corrugated vsections.

5. A metal base for fixing timber poles to the ground comprising a cylindrical metal sleeve with longitudinal corrugations di- I said sections being firmly joined/together vided into a plurality of selections by split-- ting alongthelines of the corrugations, the
