United States Patent Ofiice 3,121,608 Patented Feb. 18., 1964 Filed May 23, 1961, Ser. No. 111,973 8 Claims. (Cl. 216l) The present invention relates to an improved applicator for supporting a bandage bearing a wood treating grease product and applying the bandage to the top of a line pole.

The invention pertains to the practice of treating wood with preservatives after the wood is put in use, and particularly treating wood posts or poles such as utility line poles. The poles are treated by applying wood preservative to the top end where it can penetrate the end grain of the wood. This extends the usable life of pole already in the line and the application of preservative will add extra years to the life of the pole. Poles which were poorly treated upon installation or were not treated, or were treated with inferior preservatives can be treated with materials of an improved nature. The preservative material is a grease or rease-like composition which for convenience is carried on a sheet or bandage. For application to the tops of line poles a water soluble bandage material is employed. The preservative grease-like composition is carried in a thick deposit at the center of a sheet and the deposit or slab of grease is pressed to the top of the pole, with the sheet dissolving with precipitation.

The present invention contemplates the provision of an applicator which provides a support for a sheet carrying a slab of grease-like wood preservative material and enables the operator to apply the material to the top of the pole from the ground or a position below any crossarms or electric lines leaving the sheet and material in position for treating the pole.

An object of the present invention is to provide an improved applicator which reliably and securely supports a sheet with a slab or grease preservative on the sheet and which permits the preservative and sheet to be pressed to the top of a line pole and left there.

A further object of the invention is to provide an applicator mechanism for applying a grease bandage to the top of a line pole, having improved features for supporting the bandage, for applying the bandage firmly to the top of the pole, for releasing the bandage and removing the applicator without disturbing the bandage position, and wherein the applicator can be used for successive applications.

A further object of the invention is to provide a bandage applicator of the type described having improved means for supporting and releasing a bandage and which can be used on an electrical line pole having a ground line bracket on top of the pole.

A still further object of the invention is to provide a grease bandage applicator of simplified and reliable inexpensive construction, which is easy to use and handle in the field, and which is easy to load with bandages.

Other features, objects and advantages will become more apparent with the teaching of the principles of the invention in connection with the disclosure of the preferred embodiment thereof in the specification, claims and drawings, in which:

FIGURE 1 is a top plan view of an applicator embodying the principles of the present invention;

FIGURE 2 is a side elevational view of the applicator showing the parts in position gripping a grease bandage;

FIGURE 3 is a vertical sectional view taken substan- 2 tially along line Illill of FIGURE 1 illustrating the position of the parts as a bandage is applied to the top of a pole;

FIGURE 4 is a bottom plan view showing a grease bandage of the type handled by the applicator of the instant invention;

FIGURE 5 is a vertical sectional view taken substantially along line V-V of FIGURE 1; and

FIGURE 6 is a vertical sectional view taken substantial-ly along line VI-VI of FIGURE 1.

As shown on the drawings:

The applicator mechanism includes a support ring 10 and a lower clamping ring 11 for clamping a bandage therebeti'een. The rings are releasably held together by latches 12 which permit the clamping ring to be dropped to the position of FIGURE 3 when the bandage is to be released. When the bandage is released, carriers 13 limit the distance that the clamping ring is dropped and carry it on the support ring. The ring assembly is manipulated by an operator and has a radial arm mechanism 14 for attaching to a hot stick.

In greater detail, the support ring it is annular in shape with a gap 16 on one side that is also present in the clamping ring 11 so that the assembled rings can be moved over a pole having a ground connection, without interfering with the ground connection.

The support ring has a plurality of circumferentially spaced tapered projections 17 which form holes or openings 18 in a bandage when clamped and which extend into mating openings 18 in the clamping ring. These projections 17 project through the holes in a bandage, as shown in FIGURE 5. The support ring has a lower flat surface 15 and the clamping ring has an upper flat surface 15a for frictionally gripping the surfaces of the bandage.

The circumferential-1y spaced tapered projections 17 may also fit loosely into the mating openings 18 in the clamping ring, thereby frictionally gripping the surfaces of the bandage eliminating the need for corresponding holes in the bandage.

For holding the mechanism in the air or at the top of a line pole, the radial arm mechanism 14 includes brackets 19 on the support ring and a radial rod 21 projects into holes in the brackets and is held therein by r thumb screws 20 threaded into the top of the brackets 19. The rod 21 has a downwardly turned open U- shaped end 22 for connecting to a manually handled line pole for a lineman, which is also known as a hot stick. This will be recognized by those skilled in the art and is an elongated rod of insulating material which enables the operator to stand on the ground or climb to a position slow the crossarms or electric lines and safely raise the applicator to the top of a line pole without danger in the event the mechanism touches charged wires. While the rings iii and 11 may be constructed of various materials, they are preferably formed of a nonconductive material such as fiberglass or plastisol-coated material.

FIGURE 4 shows a bandage 24 of a type to be applied by the mechanism. The bandage has a flat sheet 24a preferably formed of a water soluble film. The film is shown with openings 27 along its edge formed by being punched by the projections 17 in the support ring when the rings 10 and 11 are clamped together. In some instances the rings may be formed without projections and corresponding openings and the bandage may be fric tionally clamped therebetween. It is also contemplated that in some instances bandages with preformed openings may be provided. It is also contemplated that an oblong bandage or shape other than round may be employed.

Although it is unhandy to prepare a bandage in the field, it can be done and it is contemplated that either 3 preprepared bandages or field prepared bandages may be used. One form of bandage is shown in FIGURE 4.

The bandage 24 includes the sheet 24a upon which has been cast a slab of the preservative-protective grease 25, for example, such as that shown in U.S. patent, Behr, 2,904,467. The grease material is cast on the supporting film 24a and a sheet of loosely woven or matted material 25a is placed over thhe preservative-protective grease. The loosely woven material may be crinoline or a water soluble material having the porosity of crinoline. A second sheet of water soluble film 24b is placed over the orinoline and is sealed to the sheet 24a at the outer edges when the bandage is originally prepared. This permits Convenient packaging and handling. In the field, whenthe bandage 24 is clamped between the rings and 11, the second sheet 24!) which is over the matted material is cut at 24c and the center portion is stripped off. The grease is exposed at the edges of the sides and through the matted or Woven material and the grease will adhere to the top of a pole when applied, as shown in FIG- URE 3. The purpose of the mat is to allow easy separation of the second sheet of water soluble film from the grease and it is not necessary that it cover the entire grease surface. Another purpose of the matted or woven material is to prevent the grease from separating from the support film 2421 after it has been clamped in the mechanism between the rings, and for this purpose a portion of the matted or woven material must extend as far as the matted openings in the clamping ring on opposite sides of the bandage. The material used for the water soluble film will be of compositions known to those skilled in the art and need not be described in detail.

I When the poles have a ground line bracket on the top, the support film is slit asshown at 26 in FIGURE 4.

The latches 1;, as shown in FIGURES 1, 2 and 6, include a latch finger 28 which is pivoted on a pin 29 suitably supported on the support ring 10. A torsion spring urges the finger 23 to a latched position as shown in FIGURE 6 in the solid line position of the finger. The latch is pulled to the release position, which is the dotted line position in FIGURE 6, to permit the clamping ring to drop down and release the bandage, by a lanyard 32. The lanyard includes lines to each of the latches 12, FIGURE 1, and as shown in FIGURE 6 the lanyard is passed through a hole 31 in the upper end of the finger 28 and knotted so that when pulled it will pivot the'latch finger 28. The lanyard 32 passes through an opening 34 in a guide 33 on the latch and passes down through an opening 35 in the support ring. Another similar lanyard 36 is connected to the other latch and passes through an opening 37 in the ring and joins thelanyard 32 to' form a composite lanyard line 38which is pulled by the operator when the bandage is to be" released.

The carriers 13 limit the distance that the clamping ring drops, as shown inFIGURE 3, and include lugs with openings 39 on the support ring. The clamping ring has similar lugs'with openings 40 and short lines 41 connect between the openings to carry the clamping ring when it is dropped down from the'clamping position of FIGURE 2 to the release position of FIGURE 3.

In operation, the operator clamps a bandage 24 between the rings 10 and'll and supports the mechanism on the hot stick 23 lifting it to the top of a pole 42. The bandage 24 is pressed down on the top of the pole 42 so that the grease-like preservative material will squeeze against thesurface of the pole causing the bandage to adhere thereto. The lanyard line 38 is then pulled and the latch fingers 28'move to the dotted line release position of FIGURE 6, permitting the clamping ring 11 to drop down to the position of FIGURE 3. The mechanism may then be elevated and the bandage will stick to the top of the pole. Elevating the hot stick will raise the ring 10 away from the top of the pole and will raise the clamping ring 11 over the top of the pole so that the mechanism can be returned to the ground for receiving another bandage to be applied to another pole.

The applicator mechanism achieves good contact between the grease preservative and the pole top and bonds the film and grease firmly to the pole, If desired, another attachment is attached to the hot stick and is used to pull the grease down evenly over the top and edge of the pole. The small amount of grease pulled down between the film in the side of the pole will bond the film neatly to the pole until rain and weather will cause to disintegrate and disappear.

Thus it will be seen that we have provided an improved applicator mechanism which meets the objectives and advantages above set forth. The applicator holds the pole top preservative treatment bandage While the bandage is prepared for application and raises it to a position over the pole top and releases the bandage so that it falls into place on top of the pole. It permits application of bandages for the top of any size or shape pole top and to poles having a ground line connection at the top.

The drawings and specification present a detailed disclosure of the preferred embodiment of the invention, and it is to be understood that the invention is not limited to the specific forms disclosed, but covers all modifications, changes and alternative constructions and methods falling within the scope of the principles taught by the invention.
