LEW/S J LOGA/V mm W HANGER FOR CABLES The present invention relates to a hanger construction for supporting pipes, cables and the like on various wall or bulkhead constructions. These constructions may be in buildings, ships, vehicles, or other structures, and these structures are often subjected to disconnecting forces such as shock loads. The invention relates also to the banding material connection between the hanger construction and the cables or pipes which are supported thereby and also relates to the tools which are utilized in making the connections.
As might be expected, many constructions have been proposed for supporting single or multiple cables which are to be connected to the bulkheads, walls, or overheads in ships. Although the prior art constructions have met with limited success in accomplishing their intended results, they have also been subject to many disadvantages. One of the most prior art constructions has utilized a hanger construction wherein a plurality of cables have been secured to a channel member by means of metal banding wherein one metal band extends completely around all of the cables. One of the distinct disadvantages of this particular construction is that if, for one reason or another, one of the cables must be removed from the connection, it is necessary that all of the cables be disconnected. A workman must therefore handle all of the cables rather than just the single one that need be removed. Another disadvantage inherent in the above referred to hanger construction is that it is usually desirable that insulation be placed next to the bulkhead or the wall after the assembly has been at least initially completed. It is difficult for a workman temporarily to remove this construction so as to be able to put the insulation in place and then replace the hanger construction with the plurality of cables secured thereto. In the above referred to prior art construction which utilizes a single band of metal material to hold a multiplicity of cables it is also difficult and inconvenient to secure the ends of the banding material which are wrapped about the cables. This is usually accomplished by means of a clip which must be properly oriented about the ends of the banding material and then it is necessary to bring a relatively cumbersome tool into contact with the clip in order to properly squeeze the same and distort the same into contact with the opposed ends of the banding material. In those prior art constructions wherein there is disclosed means of singly holding cables in place, there has been the large disadvantage of finding a convenient mechanism for securely holding each of the cables and in providing a cona venient and timesaving mechanism for quickly and yet securely holding each of the cables.
The present invention does away with all of the disadvantages mentioned hereinabove in connection with the prior art constructions in that it provides a. means for securely fastening cables, pipes or the like to a hanger construction on a one at a time basis in such a manner that if one of the cables must be removed for one reason or another, it can be conveniently and economically removed without having to remove a multiplicity of cables. By the same token, the construction to which the cables are attached can also be conveniently removed and reconnected to a bulkhead or other wall construction as the cables are being longitudinally strung. When the cables have all been finally put in place a convenient, quick and economical method has been provided for locking the entire assembly in position. This convenient and quick mechanism not only provides a lockwasher-type effect for a nut which is utilized to secure the hanger construction in place, but also provides a construction which will initially give with shock loads and which will in turn hold as well after suffering a shock load. In addition the present invention discloses a tool for conveniently and quickly wrapping the banding material which is utilized to hold a given cable in place and the tools of the present invention also provide a convenient means for removing the same from the banding material without damaging or loosening the means of securing the banding material.
Other objects and a fuller understanding of this invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

FIG. 10 is a view similar to FIG. 9 but showing the tool as removed from the wrapped band; and
FIG. 11 is a view taken generally along the line 1ll1 of FIG. 8.
The metal hanger construction of the present invention is indicated generally by the reference numeral 20 in FIGS. 1, 2, 3, and 4 of the drawings and the hanger construction is shown supported from a wall or overhead 29 by means of a stud 30 which is stud-welded at one of its ends to the wall 29 as at 31. The opposite end of the stud is provided with threads 32 and secured to the threaded end of the stud 30 is a lug member 35. This is accomplished by means of the threaded end 32 extending through a circular opening in the lug member 35 and the lug member is prevented from falling therefrom by means of a nut 33 threadably secured to the threaded end 32. The lug member 35 is provided with an angle portion 38 which is integrally secured thereto and which extends generally at right angles to the extent of the lug member. The lug member 35 is also provided with opposed raised edge portions 40. A locking member 42 is provided to cooperate with the lug member 35 for securing a channel member 48 in place in its final assembled condition and as seen fits between the raised edge por tions 40. The locking member 42 is provided with first and second end portions 43 and 44 respectively, and between these mentioned end portions is provided an elongated opening 46 through which fits the threaded end 32 of the stud 30. The elongated opening 46 permits the locking member to be moved between the position in which it is shown in FIGS. 2 and 3 (locked), and its unlocked position in which it is shown in FIG. 4.
The channel member 48 is provided with a base portion 49 which has a plurality of spaced slots 62 which extend therethrough, all of which extend generally parallel to each other. The channel member 48 is also provided with first and second flange portions 51 and 52, respectively, and the first flange portion 51 is provided with an integrally connected hook portion 54. The hook portion 54 includes first, second, and third parts, 57, 58, and 59, respectively. The first part is lug member 35, the locking member 42 assumes the position shown in FIG. 4, at which time the third part 59 of the hook portion 54 can be conveniently placed into slot 36 which is 1 provided in the lug member 35. This holds the channel member 48 loosely in position with the first part 57 of the hook portion 54 conveniently in engagement with the angle portion 38 of the lug member 35. The locking member 42 is preferably moved to the position of FIG. 2 (to hold the channel member 48 firmly) it is then convenient for a workman to secure cables in position on the underside of the base portion 49 of channel member 48.
For a convenient understanding of the invention, FIGS. 1 and 3 have illustrated cables 23, 24, 25, and 26 connected to the bottom of the base portion 49. It will be appreciated by those skilled in the art that other cables may be conveniently assembled or connected to the base portion 49 at least to the extent that space will permit. It will also be appreciated by those skilled in the art that fewer cables may be utilized if desired. In order to secure the cables 23 through26 in position as shown in FIG. 1, it is necessary for example in the case of cable 23, that a stainless steel band 64 be inserted through appropriate slots 62 in the base portion 49 of channel member 48 and brought down on either side of cable 23. The precise method of wrapping this banding material, which is preferably of a stainless steel construction, is shown in greater detail in FIGS. 6 and 7 and will be described more in detail hereinafter, but in any event, the ends of the banding material are brought downwardly in a position parallel and coextensive to .each other and the extreme ends are then rolled or wrapped in an upwardly extending manner until a roll or band is formed which is identified in all instances in FIG. 1 by the reference numeral 68. In like manner a band 65 is wrapped in a right roll about cable 24 to assume the position shown in FIG. I and another band 66 is wrapped about cable 25 as shown in FIG. I. The wrapping of bands 64 and 66 is in a direction which would appropriately be described as a counterclockwise direction as viewed in FIG. I and the wrapping of the roll 68 in band 65 is in a clockwise direction. Cable 26 illustrates how the cables can be conveniently wrapped or positioned one on top of the other in what may be referred to as a piggyback construction. In this particular instance a stainless steel band 67 is inserted through the same slots as band 64 in order to hold cable 26 and the ends of the band are wrapped in a clockwise direction so as to position the roll 68 with respect to band 67 in the manner shown.
It will be appreciated by those skilled in the art that there are a plurality of the hanger constructions positioned at appropriate longitudinal positions on a wall in order to appropriately support a run of the cables 23 through 26 which may extend along the length of a ship for quite a distance. After the cables 23 through 26 have been appropriately secured to the channel member 48 as hereinabove described, and for one reason or another it may be desired to remove one of the cablesor simply reposition it, a workman can conveniently remove the same by either cutting the band which supports it or by utilizing an appropriate tool to unwrap the roll 68. It will also be appreciated by those skilled in the art that in many constructions it is necessary that insulation be placed adjacent the wall 29 for the usual reasons. In the construction of ships for example, it is usually not possible to have the workmen who are accomplishing a given function available to accomplish their function in a given order. To further explain, it would, in most instances be desirable that the insulation be placed prior to the hanging of the cables, however, as often as not, the workmen who are to place the insulation arrive at a given area after other workmen have placed the cables. The present construction is uniquely advantageous from this standpoint in that with the locking member 42 in the posi tion shown in FIG. 4, it is quite easy to remove the channel member with the attached cables, by the simple expedient of removing the hook portion 54 from the slot 56 in the lug member. This lowers the cables at this particular position sufficiently that a workman can conveniently put the insulation in place and thereafter the hook portion 54 can be again conveniently inserted in slot 36. This same procedure can be conveniently used for all of the hanger constructions supporting a given run of cable.
After the insulation has been put in place and it is desired to secure the channel members in position, it is only necessary to move the locking member 42 by way of the elongated opening 46 to the position shown in FIG. 2. The nut 33 is then tightened, which causes a force to be exerted on the locking member 42 which in turn causes the second end portion 44 of the locking member to engage the second part 58 of the hook portion, firmly holding the hook portion in the slot 36. It is preferred that the locking member be constructed of a spring steel type material which means that a slight bowing force is exerted on the locking member as it is viewed in FIG. 2. This accomplishes two important results, one of which is that the locking member in this function and construction serves as a lockwasher to prevent the loosening of nut 33 and in addition when extreme shock loads are imparted to the channel member, or to the lug member 35 by way of the stud and wall 29, the second end portion 44 of the locking member will give slightly, taking up this shock load and when the shock load is dissipated, it again firmly engages the hook portion holding it in the slot 36 with substantially the same force as it exerted before.
FIG. 5 shows the teachings of the present invention as utilized in situations where extremely high shock loads are encountered and which require a greater holding force to assure that the means for holding the cable are not caused to become unattached. In this respect, there is shown in FIG. 5 a channel member 74 of the same construction as shown in channel member 48, and this is utilized to support a cable 71. In this construction there are utilized two stainless steel bands identified by the reference numerals 72 and 73. The first stainless steel band 72 is brought through appropriate slots 75 in the base portion of channel member 74 and the band 72 is wrapped in a counterclockwise direction so as to produce a holding roll 76. The second band 73 is then brought through the same slots 75 and this band is rolled in a clockwise direction so as to produce a roll 70. It will be seen from viewing FIG. 5 that the roll 70 which is produced has a tendency to dig or bite into the back side of roll 76 which serves to hold roll 76 extremely firmly. It is preferred that the rolls 70 and 76 be produced by rolling in opposite directions, however, under some conditions they may be rolled in the same direction.
FIGS. 6 through 11 show the tools constructed in accordance with the teachings of the present invention which are utilized for wrapping or winding the stainless steel bands (64-67, 72, 73) about the cables so as to produce the extremely tight roll of metal which keeps the bands from unwrapping. Additionally a retracting tool 83 is disclosed in combination with the winding tool, which enables the winding tool 77 to be retracted or removed from this tight roll without disturbing the roll. FIGS. 6 and 7 also demonstrate that the channel member which is utilized may be much shorter in longitudinal extent that the channel member 48 shown in FIG. I. In this regard there is shown a channel member 87 which is only of a length to handle a single cable 86 as shown. The wrapping is accomplished by means of inserting a stainless steel band 88 through slots 89 in the base of the channel member 87 and the sides of the stainless steel band 88 are brought downwardly on either side of the cable 86 in the manner indicated and the bight portion of the band is supported by the base of the channel member 87. The winding tool 77 which is utilized for wrapping the banding material 88 from the condition in which it is shown in FIG. 6 to the condition in which it ultimately is located as shown in FIG. 8, includes a work shaft 81 which has first and second end portions. The first end portion of the work shaft is provided with wall means which define a slotted end 79 which slot extends in generally an axially extending direction with respect to the axis of the work shaft. As seen in FIG. 6, the lower ends of the banding material 88 are received in the slotted end 79. A handle 78 is provided and is connected to the second end portion of the work shaft by a pivot 80. This enables the handle to be swung 180 from the position which is shown in FIG. 7 and in the direction of the arrow shown in FIG. 7. Referring to FIG. 6, the wrapping is accomplished by exerting a force on the handle to rotate the work shaft and in the direction shown by the arrow in FIG. 6. As pointed out hereinabove, the winding tool may be rotated in either direction. FIG. 7 shows the winding tool 77 as having been rotated through 90 from the position shown in FIG. 6. As will be appreciated by those skilled in the art, the amount of face which is necessary to wind the banding material can be varied substantially by increasing the length of the handle 78. The work shaft 81 is continually rotated until the banding material is completely rolled into roll 90 as it is identified in FIGS. 8, 9 and .10. It will be appreciated, particularly from viewing FIGS. 6 and 7 that because of the length of handle 78 it is only possible to rotate the work shaft a number of degrees before handle 78 strikes cable 86. For example, something slightly in excess of 180 from the position shown in FIG. 6, after which time it is necessary to swing the handle 78 about pivot 80 180 and thereafter continue exerting a force on the banding material to complete the finished roll 90. After the roll 90 has been completed as shown in FIGS. 8, 9, and 10, it will be appreciated that an extremely large force has been applied to the banding material to produce the roll and the banding material is quite tightly intertwined in the slotted end 79 of the work shaft 81.
In order to be able to conveniently remove the slotted end 79 from the finished roll 90 and in a direction generally axially of the roll, it is necessary to provide a construction which will not in any way tend to unroll the roll so as to weaken the connection which has been made. To accomplish this result, the retracting tool 83 has been provided and the retracting tool is comprised of a generally shell-like construction which has a roll engaging end 84 and a handle or lever engaging wall 85. In order for the retracting tool 83 to accomplish its intended function, the roll engaging end which is semicircular in configuration is placed against an axial end of the roll 90 as seen in FIGS. 8, 9 and 10 and the handle engaging wall 85 is brought into position relative to the handle 78 as shown. A force is then exerted by a workman on the handle 78 in a direction generally axially parallel to the axis of the work shaft and toward the roll 90. This causes an axially removing force to be exerted on the work shaft tending to pull the slotted end from engagement with the banding material of the roll yet the roll-engaging end 84 of the retracting tool prohibits disturbance of the roll 90. In this manner the work shaft is retracted.
It will therefore be appreciated that the above disclosed and described structure accomplishes the objects as set forth in this specification and does away with the recited disadvantages in the prior art. The present hanger construction provides a convenient means of quickly and efficiently connecting and disconnecting the hanger constructions from a wall or bulkhead during the initial stages of construction and provides a quick and efficient means of locking the hanger constructions to the wall when the assembly has been completed. This means of locking provides for the efficient dissipation of shock loads which are attendant in many constructions within which the hangers are found. Additionally, there is provided a means for quickly and conveniently attaching cables to the hanger constructions on a one at a time basis and the cables may be piggy-backed one to the other. This involves the wrapping of metal banding material in an extremely tight roll which serves to hold the cables in position and in and circumstances where higher shock loads are experienced there is disclosed the means of utilizing two lengths of banding material and in the preferred embodiment the two banding materials are rolled into position in opposite directions to accomplish best results. The winding and retracting tools disclosed provide rugged and efficient mechanisms for making the connections. The winding tool wraps the banding material into an extremely tight roll and the retracting tool aids in removing the winding tools without adversely affecting the completed roll.
Although this invention has been described in its preferred form with a certain degree of particularly, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
