B. SPRING POLE MOUNTING Filed March 19, 1931 lnv enToT.

George BSpTing WW wm. A I a Patented Nov. 6, 1934 OFFICE -POLE MOUNTING George BxS'pring, Newtonville, Mass., assignor to The Easter-n Malleable Iron Gompany, New Britain,-=Gonn., a corporation of Connecticut Application March 19,

1 Claim.

This invention relates to pole :mountings for poles carrying transmission lines such for instance .as telephone poles, telegraph poles, electric light poles, etc. a

5 One of thebbjectsof the invention is to provide-animproved pole mounting which is relatively inexpensive to manufacture and which canvbe easily set in the ground and on which the polemay be firmly supported with the lower end of the pole above the surface of the earth.

Another object of the invention is toprovide a pole mounting for this purpose which can be readily made at the factory :and :transported completely 'made .to the point where it is to be used. Oneadvantage resulting from this is that the improved pole mounting can be installed simply by means of the ordinary. tools used in setting a pole. I

Another objectof "the invention is to provide a pole mounting of this character whichcan be readilynsetinithe earth 'adjacent a-xpole which is in use for supporting "transmission :lines and to which suchpole can be readily transferred-while in erected position.

Other objects of the invention areto provide improvements in pole mountings .all as willbe more fully hereinafter set forth.

In'the drawing:

Fig. l-is a viewillustrating a i-poleymounting embodying my invention;

Fig. 2 is a similar view illustrating a slightly different way in which the invention. may be applied; 1 I i i Fig.3 is a View of one of the supporting mem bers with the foot portion-brokenout -leaving the post and reinforcement in elevation;

Fig. 4 isasection onthe,line14--4,Fig. 1;

Fig. is a sectionon the line :5--5, Fig. 3.

In the drawing, 1' indicates thecpole which is supported on my improved poleimounting. The pole mounting comprises one or more pole-supporting elements adapted to be set into the ground and on which the pole is supported and to which the pole is firmly clamped.

Each pole-supporting member comprises a foot portion 2, preferably of concrete, which is relatively long compared to its cross-sectional area and which preferably has a cross-sectional area somewhat less than the cross-sectional area of the pole 1. In practical use I propose to make these foot portions about five feet long. Each supporting member also comprises a post element 3 of metal which has its lower end 4 embedded in the concrete 2 for a considerable distance and the upper end 5 of which rises from 1931, Serial No. 523,786

the upper faceG ofpthe foot member for a suitable distance.-

Theinner face 7 of the .:post 3 is preferably curved to fit the exterior of thezpole andsaid posts are shown as having a general Tshape-in cross sectionand provided witha strengthening rib ,8 which extends longitudinally thereof on the back face.

.In making the supporting member the metal post 3 may be placed in a suitable mold with the upper end projecting and then the mold may rbe-filled with concrete to producethe foot portion.2 and when the concrete has set the sup- .portingmember is complete, ready for installation.

if desired, the concrete foot-portions may be t-reinforced with metal. One way of doing this 515130" provide reinforcing rods20 which extend longitudinally of thefoot portion. In the construction shown there are three such rods, one on either side of the web 8 of the post 3 and the other on the side of the post facing the pole, but the number of reinforcing rodswhich may be used may be varied without'departing from 'the invention. Ihave alsoshown a'fur- 'ther reinforcement in the form of acoarse wire mesh 21 which is wrapped around the post 3 and which provides transverse as-well as longitudinal reinforcement.

The upper, face 6 of each foot is somewhat larger than the cross-sectional dimension of the :post 3 and in the completed supporting 'member the portion 9 of the upper face 60f the foot forms a stepor seat on which the pole 1 may rest. The portion of the web or fin '8 which projects above the foot 2 is provided with a plurality of apertures 10adapted to receive clamping members by which the pole'may be clamped to the face 7.

I For supporting a relatively small pole a single supporting member may be suificient as shown inlEig. 2. In .installing the supporting member the concrete foot portion 2 is set into the earth I at the desired point with the upper surface 6 thereof projecting somewhat above the top surface 12 of the earth. The pole l is then placed in position with the lower end resting on the seat portion 9 and the pole is then clamped to the face 7 by suitable clamping devices 11 which may be of the type illustrated in my patents No. 1,679,747, August 7, 1928, No. 1,755,461, April 22, 1930 and No. 1,789,393, January 20, 1931. With this construction the bottom face 13 of the pole is spaced above the surface of the earth and is, therefore, not subjected to the decaying action which is the result of the pole being in contact with the earth.

This mounting can be constructed complete at the factory and transported in its complete form to the place where it is to be installed and it may be as readily set into the earth as an ordinary pole so that no special tools are needed for installing the mounting other than such as are commonly used in setting a pole.

After the mounting has been set the pole can be easily attached thereto by placing the lower end 13 of the pole on the seat 9 and then applying the clamping members 11 which securely clamp the pole to the posts. The posts should have a sufficient overlappingengagement with the pole to hold the pole firmly. I

For mounting large poles I propose to use two of these supporting members as shown in Fig. 1. Each supporting member may be independently set in the earth and arranged so that the lower end of the pole may be placed between them, the pole being supported partially on the seat portion 9 of one supporting member and partially on the seat portion 9 of the other supporting member. I

After the polehas been put in position the two supporting members are clamped firmly to the pole by means of clamping elements 15 which are connected to the ribs 8 of the posts and which engage the side faces of the pole exposed between the posts.

In making the foot portions 2 I preferably will so form them that the inner faces 16 thereof are somewhat pointed in a transverse direction. When the two supporting portions are employed the two pointed ortapered sides 16 face each other as seen in Fig. 4. An advantage of this construction is that the pointed shapes of the foot portions facilitate their being drawn together slightly in order to enable the upper ends of the posts to be firmly clamped to the pole.

' In installing the pole mounting shown in Fig. 1 the two supporting members will be set in the earth at approximately the correct distance apart to accommodate-the pole which is to be set, this distance varying with the size of the pole. After the pole is placed in position with the lower face 13 thereof resting on the two seat portions 9 it may be found that the upper ends 5 of the posts 3 do not fit tightly against the pole. When the clamps 15 are applied the upper ends of the posts will be drawn tightly against the pole and the pointed shape of the faces 16 facilitates any slight movement of the foot portions 2 toward each other necessary to permit the posts to be firmly clamped to the pole. These tapered or pointed surfaces 16 tend to crowd the earth away so as to allow this necessary movement.

My improved pole mounting may be used for the mounting, of new poles or may be used as a support for a pole which has been in use and which has become more or less decayed at the surface of the earth. In the latter case the decayed pole will be cut off close to the earth while still in its erected position and the lower end of the pole may then be set slightly to one side. The two supporting portions may then be set in the earth at approximately the proper distance apart to accommodate the pole and with the upper surfaces 6 of the foot portions extending a short distance above the surface of the earth. After the two supporting portions have been set the pole may be placed between the upper ends of the posts 5 with the lower end resting on the seats-9 and the clamps 15 applied to clamp the pole firmly in place.

These operations can be carried out without disturbing any of the wires carried by the pole.

If desired, the seats 9 may be formed with drain grooves 17 which allow the water to readily drain 01f from the seats thus preventing the accumulation of water at this point which might have a tendency tocause decay. It will be noted that the foot portion has a larger cross-sectional area at the upper end than at the lower end. The advantage of this is that the larger upper end gives an increased earth resistance at the surface of the earth where this is most needed. At the lower end of the foot some distance below the surface of the earth the earth will present a greater resistance than at the surface of the earthwhere it is more easily crowded to one side and. by making the upper end of the foot portion larger an increased earth resistance is provided at the surface of the earth where such increase is most needed to prevent the pole from swaying.

I claim:

' A pole mounting comprising two pole-supporting members each having a foot portion of concrete adapted to set into the earth with the upper end of the foot portion projecting slightly said faces filled with earth, and also being pointedto facilitate the drawing of the foot portions together in the earth as the posts are clampedto the pole said foot portion having a progressively-increasing cross-sectional area from the bottom to the top whereby the larger end presents an increased surface for earth resistance.
