4Claims. (o1. 304-2s This invention relates to stands, and specifically to a type of stand which port for linemen.
When it becomes necessary to examine and make repairs of telephone orotherwires carried on a cross-arm attached tova pole, thelineman must have some type of device which will support him 'while the repairs are made. Often spikes attached to the shoes are used, together with a safety belt. A platform may be secured to the pole or other unwieldy and heavy devices may be employed which, of necessity; require time to erect onthe part of the lineman. g 1 a An object of the present invention is to provide a stand which may utilize such objects in forming the stand as are usually carried in the truck accompanying the lineman such, for; instance. as a cross or wing arm of thegtype generally employed on a pole for supporting wires. This cross or with a member which is readily secured to the telephone or telegraph or electric wire pole, whereupon the lineman may stand upon the wing orcross arm forming the support.
The average telephone orelectric light pole is formed of wood which has been impregnated with creosote to preserve the same. creosote, or other preservative, is a ready conductor of electricity, and sometimes when the lineman stands on a platform which is attached to the pole, the platform being in part formed of metal, the lineman is electrocuted or seriously burned when heat tempts to operate upon the line due to short .Clls cuit from the line through the pole to theground. The present invention overcomes this hazard in that it uses an untreated wing or crossarm which effectively acts as an insulating member for the lineman to stand upon.
The invention incorporates a structure which is simple of construction, inexpensive'in cost of manufacture, readily erected, is fool-proof; and
safe in operation, and generally superior to devices now known to the inventor for formingav platform for a lineman.
With the above mentioned andother objects in view, the invention consists in the novel anduseful provision, formation, construction, association, and relative arrangement of parts, members and features, all as shown in certain embodiments in the accompanying drawings, describedgeherally, and more particularly pointed out in the claims.
In the drawings:
Figure 1 is a fragmentary perspective view of a to may be utilized as a suppole upon whichis secured one form of the invention, i
Figure 2 is an enlarged perspective view of an element which is utilized in the practice of that formof the invention shown in- Figure l and included within the circle 2 of Figure l,' perspective view of a bracket Figure 3 is a which may be used in lieu of the type of bracket shown in Figure 2 in the practice Ofthe invention,
Figure 4 is a fragmentary enlarged sectional view on the. line 44 of Figure Figure 5 is a fragmentary side elevation of the device shown in Figure 4,
Figure 6 is a sectional view on the line 6--6 of Figure 4.
Referring now with particularity to the drawings, and specifically to the form of the invention shown in Figures 1 to 6,inclusive, the invention y wing arms attached 'stitute one of the wing arms be replaced. The
includes as elements a shoe "i adapted to be secured. to a pole 2, and which shoeis formed to carry a platform 3. A bracket 4 is utilized for bracing andaiding in the support of the platform 3, this bracket being so formed as to readily engagea brace 5 extending between the pole 2 and the wing arm or cross-arm 6. It is ordinary practice to secure a wing arm 6 to the pole 2 at a certain elevation above the ground, and it is also ordinary practice to provide a number of said at different levels to the pole. These wing arms carry the usual insulators 7 to which are secured wires 8. f f
It is often necessary for linemen to make repairs to the insulators 1 or the Wires 8 Where they are carried by the wing arms. To do this, particularly if it is necessary to ,workadjacent the always carried by linemenin a arms which have deteriorated therefore, the curvature of the plate 9 is readily determined in advance. The plate 9 is provided with a socket member ID which, in the present instance, is in the form of an elongated quarecross-section tube, so shaped in order to accom- NT OFFICE y tially in alignment'with of a bolt I4 passed through the lug apertures and an aperture in the arm. The said arm carries an outstanding pair of aligned lugs and |6,-between which is received the end link ll of a and a returnedly bent part 49 which embraces the niner surface of leg 39. The returnedly bent portion 49 carries a' set screw M for locking said part to leg 39.
The form of the bracket shown in Figure 3 does not differ in essential details from the form shown in Figure 2, save and except that the portion 42 which overlies the leg 35 ofthe brace chain l8. A bolt I9 is passed through the apertures in the lugs l5 and i6 and through the end link ll. The plate 9 carries a bifurcated hook 29 adjacent plate end 2|. This bifurcated hook is adapted to have a link of the chain passed therethrough, as illustrated in Figure 4, and for securing the said chain. Secured to the socket l9 and outwardly extending from a side thereof is an angle iron member 22. the edges of the angles may be toothed or notched, as shown at23 and 24, and likewise the notched edges may be curved to conform to the swing of the arm l3 relative to itspivot point, which would be the bolt l9. The arm I3 is longitudinally slotted at 25, and a slide bolt 26 is passed through said slot, and carries a wing nut 21. This slide bolt is headed and adapted to be received within some one of the notches or teeth 23 so as to lock the arm l3 against movement when the wing nut 21 is tightened, as will hereinafter appear in the statement of operation. In
addition, and as a, safety precaution, as previously stated, one leg of the angle iron member 22may be provided with the notches 24, and when this construction is followed, the arm 13 carries a Either or both of 5 is provided with a returnedly bent portion 43 for engaging the inner surface of the leg, and this portion 43 is provided with a setscrew 44 for :locking the bracket to said leg. The portion 45 of the bracket is adapted tosupport a portion of the platform 3 and is provided with a rightangled end 46 for engaging a side of the platform.
The operation, uses and advantages of the invention are as follows:
When it is desired to make a repair upon a line or a wing arm, the lineman may ascend the pole 2 in the ordinary manner, either with spiked boots or use the usual steps to the point desired. If
plate 28 receivable within certain of the said notches 24. Thus, when the wing nut 21 is tightened, plate 28 will beheld securely within one: of
the notches.
It is intended that the construction described should utilize one of the ordinary wing arms, such as shown, for example, at 6 in Figure 1, and
the wing arm has an end thereof received within the socket l9. The bolt 29 is passed through two sides of the socket and a hole in thewing arm, which constitutes the platform, as shown in Figure 4. In addition, a set screw 39, carried by the socket may be tightened against the platform, as shown in Figure 5. In this manner, the platform is held within the socket and against .removal.
The plate 9 is provided With one or more pins 3! which are adapted to. impale or penetrate the pole when the chain 18 is tightened therearound, as see Figure 4. 1
As the present type of platform is not of the cantilever, type, a bracket, such as shown in Figtwist at 33 so as to provide a portion 34which overlies and rests upon a surface of one leg35 of the brace 5, while the portion 36 is substanthe socket memberl9, to the end that the platform 3 which rests on portion 36 would be held in parallel alignment with the wing arm 6. Secured to portion 36 is a rightangled end 31 while secured to aportion 34 is a 'downwardlyextending part 39, adapted to em-.
brace the outer surface of the leg 39 of brace 5 we assume that the point is somewhere beneath the wing arm, the lineman either carries with him or has drawn up to him by means of a rope, the
shoe l and platform 3. He first loosens wing nut 21 and slides the bolt outo-f engagement with'the notches 23. The shoe 9 is then placed against the pole at the desired location and the chain I8 is wrapped around the pole, as shown in Figure f1, with one of the links received betweenthe' bifurcations of hook 29. The lever I3 is then moved to tension the chainand to cause the pins 3l to impale the pole. Bolt 26. is then. moved into engagement with one of the notches 23 of member 22 and the wing nut 21 tightened. This tightening of the wing nut will position th member 28 within one of the notches 24, and in this manner, the lever i3 is prevented from'moving. The bracket 4 of either type'as shown in Figures 2 and 3, is then positioned on brace 5 and thereafter the platform 3 is held so positioned as to rest upon the portion 3Binthat form of the bracket shown in Figure 2, ortheportion of the bracket form shown in Figure 3-,'with an end part 46 in the form of bracket shown in Figure 3. The platform is secured against movement Within socket I9 by means of bolt 29, which is passed through the aligned bores in the platform and the socket and may likewise be held secured by means of the set screw 39. The lineman may thereafter stand on theplatform. 3 and perform such repairs as necessary and at any point. of the wingarm 6. d
That form of the invention showninFigures 7 and 8 operates upon the same principle, save and except that a bracket is not utilized for supporting the platform. In properly positioned on the pole in the manner which has heretofore been set forth and thereafter the platform 59 has the part 52 received within the'socket l9 and secured to the socket bymeans of a bolt 29. The enlargement 52 braces the platform so bend appreciably under the weight of anormal man.
