1 Claim.

This invention relates to conductor pipe hooks.

and methods. of making the same;

It is the principal object of the present invention tio provide an improved conductor pipe, hook which is rigid and which isparti'cularly suitable for retaining plain or corrugated, rain spouting and the like from slipping" with respect to the conduct-or'band'.

It is a further object of the present invention to provide a conductor. pipe hook which is capable of permanent attachment to the pipe.

It is a further object of the" present inventionto providea conductor-pipehook having an improved drive which is adapted for mounting and gripping in either wood or-masonry; as desired.

It is a further object of the present invention to provide a conductor pipe hook having improved provisions for securing the same in place in a wall, or the like.

It is a further object of the present invention to provide improved methods of making conductor pipe hooks of the character aforesaid.

It is a further object of the present invention to provide improved methods of forming conductor pipe hooks in which the strength of the I material is retained after formation of the pipe hook and in certain respects enhanced.

Other objects and advantageous features will be apparent from the specification and claim.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a view in perspective of a unit length of channel section from which the conductor pipe hook in accordance with the present invention is formed;

Fig. 2 is a perspective view showing one stage in the formation of the conductor pipe hook;

Fig. 3 is a perspective view showing another stage in the formation of the conductor pipe hook;

Fig. 4 is a perspective view showing certain of the bending operations at another stage in the formation of the conductor pipe hook;

Fig. 5 is a view in perspective of one form of completed conductor pipe hook;

Fig. 6 is a view in perspective showing another form of completed conductor pipe hook;

Fig. '7 is a fragmentary elevational view illustrating certain of the details of the conductor pipe hook between the band and the drive; and

Fig. 8 is a fragmentary sectional View taken approximately on the line 8-8 of Fig. '7.

Bike numerals refer to likepartsnthroughouta the severalviews.

It should, of course, be: understood that the description and drawings. herein are illustrative A merely; and that various modifications; and? changes may be madein the structure disclosed without departing from thespirit of thevinuene tibn".

Referring now: more particularly to; the drawei'ngs, there is illustrated in- Fig: 1, aunitlength: of channel it from which. the conductor: pipe; hook is made; the channel. preferably: being; Qii wrought steel rolled to the desired cross; seetion and withv a. web lit and flanges l2; The

- length. of channel as is; preferably out; from. a.

longer piece in any desired manner.

As the initial steps to be performed on the length of channel, and as indicated in Fig. 2, one end l3, which is to form the terminus of the band of the hook, is preferably rounded and portions of the flanges l2 adjacent thereto are cut away. At the other end M, which is to form the drive of the hook, the flanges I2 are cut away and the terminus I5 of the end 14 is formed into a blunt chisel shape.

The flanges l2 and the web H intermediate the midportion of the unit length of channel Ill and the terminus l5 are tapered as at It with respect to the longitudinal axis and inwardly towards the terminus I5. At any preferred stage during the formation of the conductor pipe hook, and preferably while the ends of the unit length of channel Ill are being formed, a plurality of holes l3 are preferably provided in the web ll of the unit channel I!) and extending therethrough for purposes to be explained. As a further stage in the formation of the conductor hook, the flanges 2 at the section M are preferably fiattened and spread inwardly into contact with each other as illustrated at E9 in Fig. 3 to complete this portion of the conductor hook.

The unit length of channel [0 is then bent, intermediate its ends, by a multiple bending as at 20, by which a short leg 24 of a portion H of the unit length It is disposed at an angle slightly less than a right angle with respect to the remaining portion M of the unit length and also twisted through an angle of degrees so that, upon the completion of the bending, the longitudinal axis of the portion I1 is disposed in the same plane as the longitudinal axis of the portion M of the unit channel piece I0.

The band is then formed in the portion II beyond the leg 24 of the desired shape and may be arcuate as indicated at 21 in Fig. 5 for use with conductor pipes of circular or circular and corrugated cross section, or may have a flat portion 22 disposed at right angles with respect to the drive I4 as indicated in Fig. 6 with an end 23 disposed at 90 degrees with respect to the flat portion 22, for use with conductor pipes of square or rectangula cross section.

A conductor pipe hook is thus provided having a drive 14 with a chisel point l at the end for penetrating wood or masonry. The drive 14 has a tapered portion adjacent the terminus l5 for engagement with the wood or masonry in which the hook is to be mounted, and with a tapered recess or open space 25 closed at one end by the flattened flanges 19, which provides a gripping channel for retaining the conductor pipe hook in fixed engagement upon insertion.

The offset of the band 2| or 22 by the leg 24 from the longitudinal axis of the drive l4 provides for convenient access for hammering in alinement with the axis of the drive, thereby facilitating the insertion of the hook.

The interior of the band, eithe of arcuate shape, as illustrated in Fig. 5, or of flat shape with an end hook, as illustrated in Fig. 6, provides surfaces for gripping engagement with the exterior of the conductor pipe. The holes 18 are provided for the insertion of self tapping metal screws 26, which, by their engagement with the conductor pipe (not shown), prevent the conducto pipe from slipping or moving with respect to the pipe hook after assembly.

I claim:

A conductor pipe hook comprising a unitary length of channel having a band portion at one end with the flanges of the channel extending therealong on the interior thereof, a driving portion at the other end with the flanges of the channel extending therealong, said driving portion having a tapered terminal end portion with a blunt point and a longitudinally extending channel closed at the end adjacent the terminus with the flanges in flattened relation to the web, and a connecting portion between said band portion and said driving portion, said connecting portion having the flanges of the channel extending along the interior thereof, and said band portion having a plurality of spaced openings through the web between the flanges for the reception of fasteners for engagement with the conductor pipe.
