This invention relates to stubbing devices and more particularly to devices for securing together two adjacent poles or securing the base of one pole to a stub pole, as is sometimes necessary.

After the poles of telephone lines or electric light lines, or the like, have been in the ground for a period of time they are subject to decay at or below the ground line and become quite weak at this point. It is either necessary to remove the pole and install a new one or in some way provide means for making the base of the pole secure. If the pole is removed and a new one installed, it means, of course, that the wires, cross arms, etc, must all be removed from the old pole and placed on the new one, so that aside from the necessary new equipment, a considerable amount of labor is involved.

It has been found satisfactory in many instances to avoid replacing the pole with a new one by inserting a stub pole or short pole into the ground adjacent the old one which has become decayed, leaving several feet of the stub pole projecting above the ground line. The old pole is then secured to the projecting portion of the stub pole by passing straps or hands around both and securing them as tightly together as possible. It

of course, desirable that the means for securing the poles together be so arranged that the old pole will be secured rigidly and firmly to the stub, and to this endit is advantageous to provide means for drawing the straps or hands tightly about the poles after they have been mounted thereon.

It is also desirable to connect the parts of the securing means so that there will be no relative slippage or movement between such parts and no tendency of one part to roll or slide on the other.

One object of my invention is the provision of a new and improved stubbing device or means for securing adjacent poles together, such that the device may be readily and easily secured in place and serve to bind the two poles rigidly and securely together.

Another object of the invention is the provision of a stubbing or pole-securing device having provision whereby the straps or bands which embrace the pole may be tightened or drawn together by bolts passing between the poles, the bolt-securing devices being so arranged that there will be no possibility of movement between them and the pole-embracing straps.

A still further object of the invention is the provision of a pole-securing or stubbing device which will be positive and eftlcien-t in operation and at the same time may be economically manufactured. and readily installed in place.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

To illustrate one preferred embodiment of my invention, I have shown a pole is which has been out off as at ll adjacent the ground line It and secured by my improved securing devices to a stub pole i i set into the ground adjacent the pole it and permitted to project several feet above the ground line beside, and closely adjacent to, the pole Ill.

As illustrated, a U-shaped rod or bolt i5 is employed to embrace the outer side of each of the poles Ill and it. These members 55 may be of any desired shape, either fiat or round in cross section, so far as concerns the main portions of their lengths. The ends of these members, however, are preferably round so as to be threaded, as at Hi, to receive the nuts ii.

The adjacent ends of the members l5 are connected together, as shown in Figs. 1 to 3, by means of bracket members designated generally by the numeral i8. These brackets consist of end portions is which may be suitably curved to present a surface or" substantially arcuate shape to lie closely adjacent the poles, and intermediate or web portions 28 connecting the curved ends and lying adjacent the space between the poles.

The web portions 29 are provided with openings iii to receive a bolt 22 which upon one end will preferably be provided with threads to receive the nut 23 so that the nut may be taken up upon the boltand tend to draw-the bracket members toward the poles. It will be understood that the bolt 22 passes between the adjacent poles.

The end members IQ of the brackets may be bifurcated as shown at 24 and provided with upstanding lugs 25 having slots 26 provided therein to receive the ends of the U-shaped members or bolts I5. Flanges 2! may be provided upon the lugs 25 adjacent the slot 26, against which flanges the nut Il may bear so that when the nuts are taken up upon the bolts I5 the latter will be drawn tightly against the outer surfaces of the poles.

The web portion 26 of the bracket may be provided with a boss 29 about the opening 2i and also be provided with upper and lower flanges 28 to strengthen the central portion of this part of the web and prevent it from bending too sharply when the web portions of the brackets are drawn together by the bolt 22.

In installing the device, the members I5 are placed about the pole and their threaded ends inserted through the slots 26 in the lugs 25. Nuts I! are then placed upon the threaded ends of the members It and taken up to draw the members I5 as closely as possible about the outer sides of the poles. When this has been done the bolt 22 is passed through the openings 2| and the nut 23 taken up upon the end thereof to draw the web portions 26 of the brackets I 8 inwardly toward the poles and effect a consequent additional drawingaction upon the members IE to cause these members to engage the poles more tightly. The Web portions 29 of the brackets will ordinarily be sufficiently resilient to permit this result to be accomplished.

It will be understood that due to the shape of the end portions I9. and due to the fact that the bolt 22 is secured to the bracket members by passing through openings therein, the bracket members will be held in their initial positions upon the poles and will have no tendency to travel. Moreover, by providing for taking up any slack or looseness both at the ends of the bolts I5 and by means of drawing the brackets together by the bolt 2|, it will be possible to secure the two poles rigidly together so as to make the most rigid connection between them.

As shown in Fig. 1, two of my devices are employed in connection with the poles It and I -3. It will be understood, however, that any suitable number of these devices may be employed, depending upon the size and height of the poles.

In Figs. 5 and 6 of the drawings I have shown a stubbing device having a bracket of somewhat modified form. This bracket is similar in some respects to the bracket I8 shown in Figs, 1 to 4. The bracket I8, however, is intended to be somewhat resilient so that its central portion will draw in between the poles and thus cause the bolt or embracing members I 5 to bind tightly around the poles. The bracket 35 is designed to be of the rigid type and eifects a binding action of the bolts I5 by drawing in the ends thereof from the position in which these ends stand when they are inserted through openings of the bracket. That is, in this instance, the entire bracket will move inwardly toward the poles instead of the bracket itself being bent out of its original shape.

The bracket 30 has a central v-shaped web portion 3i and side flanges 32 and 33, these flanges being of such a nature that they will stiffen the web portion of the bracket and prevent any appreciable bending thereof. At their ends the flange portions 32 and 33 are connected by end flanges 3A and 35, provided with slotted openings 36 and 31 through which the ends of the bolts I5 are designed to be inserted. Nuts I! may then be threaded upon these bolts to take them up until they are set closely to the poles.

The central web portion 3| of the bracket 30 is provided with an elongated bolt opening 38 to receive the bolt 39 passing between the poles, as has already been explained in connection with the'form of my device shown in Figs. 1 to 4 of the drawings. The surface of the web 3| about the opening 38 is rounded, as shown at 40, to provide a seat or socket for a washer II, placed upon the bolt 39. This washer has its lower surface rounded to some extent to fit against and rock over the surface 411.

It will be understood that in this form of my device there will be a bracket 3i upon each side of the pair of poles, or the pole and stub pole, as the case may be. After the bolts I5 have been placed in an embracing position about the poles, their ends are inserted through the openings 36 and 31 and the nuts I! tightened thereon. The bolt 39 will then be inserted through the brackets and the nut 40 taken up to draw the brackets towards the poles and thus cause the bolts I5 to bind tightly about the latter. t will sometimes be found that the openings 38 do not exactly register upon opposite sides of the poles or that the bolt 39 when passed through these openings does not occupy a position coinciding with the axis of the openings 38. It is for this reason that these openings are slotted or enlarged with respect to the bolt 39 in a direction longitudinally of the web 3|. As the washer 4| upon the bolt 39 is provided with a rounded lower surface complemental to the surface of the seat or socket d0, this washer will tend to seat itself in the proper position so as to permit the bolt 39 to lie at an angle to the axis of the opening if it naturally assumes such a position. This provides for an easy insertion of the bolt 39 and also relieves strain upon the parts while in use.

In Figs. 7 to 10 of the drawings I have shown a further modified form of my invention wherein bolts or embracing members I5 are placed about the poles and have their ends received and held in brackets 45. Each of the bracket members consists of a front plate member it, provided with a central opening 4'! and having upper and lower flanges 48 and 49 projecting rearwardly from the front face so as to project toward the poles when the bracket is in place. Strengthening web members 5d and 5| may be provided at the central portion of the bracket adjacent the opening 41, these web members forming in conjunction with the flanges I? and 59, channels or sockets 52 and 53 upon the rear side of the plate A5 to receive the ends of the bolts I5. At the ends of these channels are provided Web members or lugs 54 and 55 having openings 56 and 57 through which the ends of the bolts may pass for the reception of the nuts I'I.

It will be apparent that in the use of this form of device the ends of the bolts overlap as each enters one side of the bracket, and passes through the same to have its threaded end project from the opposite side. In the form shown, the brackets used upon opposite sides of the bolt are duplicates and for this reason the bolt I5, which enters the upper channel 52 upon one side of the pole, will enter the lower channel 53 of the bracket upon the other side of the pole.

For this reason the bolts I5 are not in a true horizontal position and it will be seen that the channels 52 and 53 are slightly inclined to' allow for this departure from the horizontal, that is, the openings or notches 58 and 59 between the webs 55 and 55 and the flanges 9 and 48,.will not be in true horizontal alignment with the openings 56 and 5?, and the side edges of the bracket, as shown in Fig. '7, are not precisely at right angles to the upper and lower edges. When the fitting ias been installed, however, and tension applied to the bolts, the side edges of the brackets will be drawn substantially to a vertical position. If desired, the brackets might, of course, be made right and left-hand so that both ends of one of the bolts would enter the upper channels or the lower channels, as the case may be.

It will also be apparent that as the ends of the bolts are at different levels in the brackets, the tension thereon will exert a force which will act as a couple, tending to turn or cant the bracket from the position in which it is first installed. This will, of course, be resisted by contact of the bolts against the surrounding material of the bracket, as any great amount of canting of the bracket would serve to bend the ends of the bolts.

When the fitting shown in Figs. 7 to 10 is installed, the bolts !5 are placed about the poles and their ends inserted through. the channels 52 and 53 and the nuts i? drawn up upon the bolts. The bolt 56 is then inserted through the openings il and the nut 65 drawn up to urge the brackets toward the poles and thus cause the bolts to bind e poles. of Fig. 8 it will be seen that when the bracket 1' drawn inwardly the bolts 55 will assume a position against the front plate-l6. If a continued inward movement of the bracket is ei'iected this will cause a reverse bending of the end of the bolt adjacent the edge of the bracket, which will, of course, be resisted by considerable force. P. or to this time, however, the ends of the bolts will be drawn inwardly from the posiin which they stood when they were inserted into the brackets, and the bolts will in all probability be tightly bound to the poles when the fitting reaches the position shown in this figure of the drawings.

While I have shown and described some pre i'errec embodiments of my invention, it will be understood that it is not to be limited to the details shown but is capable of modification and variation within the spirit of the invention and the scope of the appended claims.
