PIPE STANCHION Filed May 7, 1934 mlllllil) INVENTOR MAX E. R/T R WM/ ATTORNEY Patented June 30, 1936 A'TENT orries 2 Claims.

The present invention relates to stanchions and particularly to improvements in stanchions for supporting pipes or the like;

The old method of burying water and'steam pipes, etc., in the earth has in recent years been replaced by providing a concrete lined tunnel in which the pipes'are laid. This affords readyaccess for repairs, additions, etc without the need for continual breaking of pavements and laborious excavations. I

It has also been the practice in the past, to provide regularly spaced stanchions to properly'support the pipes at required intervals and in desired relation to the tunnel Walls and to each other. Such stanchions were either fastened by means of expansion bolts to. the walls, floor, or ceiling of the tunnel and therefore entailed considerable drilling of holes in the concrete and cutting and fitting of the stanchion parts, or the stanchions were of the screwjack type with threads of opposite hand at the ends of the vertical members requiring the use of pipe wrenches for assembling. The vertical members, usually iron pipa were therefore cut and mutilated and even after final assembly there was; no assurance that vibration would not loosen them in the screw seats of their head and base castings. It is further apparent that regular pipe threads could not here be used and therefore, special threading dies must be designed to cut a non-tapered threaded portion at each end of the vertical pipe member and since the threads at each end of the pipe are of opposite hand, this became doubly expensive.

The present invention, therefore, contemplates a pipe stanchion of improved design in which the faults above set forth are eliminated and wherein the parts comprising the stanchion are simple in construction and economical to manufacture.

Another object of the invention resides in the provision of a pipe stanchion in which'the parts may be made in a shop with ordinary standard equipment, no special tools or dies being required.

A further object is to provide a stanchion in which the vertical and horizontal members are merely cut to a specified length and require no threading whatsoever and thereby affording a most economical arrangement.

A still further object of the invention lies in the provision of jack means at the base of each vertical member of the stanchion, the rotatable member of the jack means being provided with a cup receptive of the lower end of said vertical member and with means to lock the rotatable member after assembly and thereby preventing loosening of the assembly due to shock or vibration.

Whilethe present disclosure deals with that embodiment of the invention which relates to stanchions for supporting pipes or the like, the invention may conceivably, be employed in divers other fields and further objects of the invention will become apparent from the following description of the illustrated embodiment'thereo'f and in which: I

. Fig. 1 is a cross-sectional view through a pipe line tunnel showing a stanchioniin elevation.

Fig. 2 is an enlarged, broken, detailed view of one of the. vertical members of the stanchion and its related fittings.

Fig. 3 is a vertical sectional view as taken along the line 3-3 of Fig. 2.

Fig. 4 is a cross-sectional view as taken the line 44 of Fig. 2.

The tunnel, shown at 5, comprises the ceiling 6, floor? and side walls 8 and may be of the usual concrete-construction, and may be made willciently wide to provide walking space along one or along both sides of the stanchions therein. 7

The stanchions,;comprising the present invention are each essentially formed with the vertical pipe members 9 and one or more horizontal pipes I0.

At the top end of each vertical member 9 there is preferably provided a head II, of cast metal or the like, having a socket I2 receptive of said top end of the member 9.

That surface of the head I I which contacts the ceiling 6 of the tunnel may be provided with knurls or may be otherwise roughened as at I3 to afford effective and nondisplaceable contact at that point.

Each vertical member is provided at its lower end with a screw jack comprising the base member I l having a screw seat I5 in which is rotatably engaged a member I6 having the threaded shank IT. The member I6 is also provided with a cupped seat I8 in which may be placed the washer l9 against the top face of which the lower end of the vertical member rests.

The member I6 is preferably formed with means such as the hexagonal portion 20 whereby it may be turned in its screw seat I5 and after final assembly a lock nut such as shown at 2| may be employed to lock these associated parts against inadvertent displacement.

The base member I l may be knurled or roughened at 22 in a manner similar to the roughening at I3 of the cap I I to afford nondisplaceable contact between it and the floor 1 of the tunnel.

To accommodate means whereby turning of the base I4 is prevented during raising of the part IS, the base is formed with openings or notches 23 through which a rod, bar or the like may be passed. One end of the bar may be rested against a side wall 8 of the tunnel and thereafter rotation imparted to the part l6 would not displace the base during the assembly operation.

The uprights of each stanchion may be quickly assembled with the aid of one tool-a wrench to fit the hexagonal portion 20 of the jack member l6 and the lock nut 2|. The length of the pipe 9 may vary within a certain range and still permit of proper assembly. The parts, other than the pipe 9, comprising this assembly may be of inexpensive cast iron requiring no machining except the threaded bore of the base l4 and the thread on the shank H, which may be of a standard diameter and pitch for the purpose.

, The cross member or members of the stanchions may simply be the pipes Ill, each supported at theirends in saddles 24, positioned on the vertical members and securely held thereon by V-bolts 25. The cross pipes Ill need not necessarily be fastened into position, but could be merely rested in the saddles as shown. Slight variations in the lengths of these cross pipes would not interfere with the assembly.

When the pipes P, to be supported are laid on the cross members they are effectively held from displacement which can only be accomplished by lifting them, out of their saddle supports. If however, it should become necessary to replace one of these cross members, it is only necessary to loosen one saddle, slip it down along the pipe 9, extract the pipe l0, replace it with another and move the loosened saddle back into position.

Any expansion or contraction in the pipes P can normally take place without any tendency to strain the stanchion assembly since the cross members l0 may roll in their saddle supports which for the purpose are made smooth.

Although I have described my improvements with considerable detail and with respect to certain particular forms of my invention, I do not atlases? desire to be limited to such details since many changes and modifications in the form, arrangements, proportions, and sizes thereof, may well be made without departing from the spirit and scope of my invention in its broadest aspect.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a pipe stanchion adapted for use between opposed upper and lower surfaces, an upright comprising an intermediate vertical member, socket means at each end of the member, one of said socket means having contact with one of said surfaces and jack means between the other socket means and the other of said surfaces, said jack means comprising a base having contact with the last mentioned surface, and provided with notches receptive of means to prevent turning of the base during assembly of the upright, said other socket means having a shank integral therewith -and threadedly engaged in the base and means to lock the shank against inadvertent movement in the base.

2. In a pipe stanchion adapted for use between opposed upper and lower surfaces, an upright comprising an intermediate vertical member, cap means disposed between the top of the vertical member and the upper surface and jack means between the lower portion of the vertical member and the lower surface, said jack means comprising a base having a threaded bore, and provided with notches receptive of means to prevent turning of the base during assembly of the upright, a one-piece rotatable member having on one end a socket for the reception of the bottom of the vertical member, and its other end externally threaded to constitute a shank in threaded engagement with the base, said rotatable member having intermediate its ends, a portion provided with flats for the application'of a wrench, and a lock nut on the shank between the said portion and the top of the base member, adapted to lock the rotatable member against inadvertent movement in the base.
