Specification of Letters Patent.

Patented se t. a, 1914.

Application filed August 11, 1813. Serial No. 784,129.

'1 '0 (/71 whom it 711 03/ concern lie it known that I, \ViLLIA B. GRAY, a citizen of the United States, and a resident of Louisville. in the county of Jellerson and State of Kentucky, have invented a new and useful Improvement in Pipe -Supports, of which the following is a specification.

My invention is an improvement in pipe supports, and has for its object to provide a support. especially adapted for supporting heating, steam pipes and the like, in earthen onduits of the character shown in my copending application, Serial No. 723,206, filed Sept. 30, 1 912, or in other conduits, wherein a cradle is provided for engaging the conduit and a saddle for engaging the pipe, to gciher with mechanism for connecting the saddle and the cradle to permit relative longitudinal movement of the saddle and cradle, and wherein other mechanism is provided for preventing relative vertical movement of the cradle and the saddle.

In the drawings :Figure 1 is a perspec tive view of the improved support, Fig. 2 is a top plan view of the saddle detached, and Fig. 3 is a transverse vertical section.

The present embodiment of the invention comprises a cradle 1, having a pocket or depression 2, on the upper face of its bottom, provided with a series of transversely arranged teeth. The side walls 4 and the end walls 5 of the pocket are approximately perpendicular on their inner faces, and the cradle is provided at its opposite sides with laterally extending supporting fingers or lugs (3, the said lugs being near the opposite ends of the cradle.-

The lugs or fingers 6 are adapt-ed to rest in pockets. in supporting ribs or ledges in the conduit. and the said fingers are held in the pocket by means of a filling of cement or lead. or other plastic material, capable of hardening.

In order to provide a lock, each of the fingers is grooved on its outer side as indieated at i", the said grooves being adapted to receive the plastic material to form a lock when the said material hardens.

The cradle is also provided at each of its sides with an rip-standing rib 8, and each rib is provided at its upper edge with an inwardly extending flange 9. the said flange being approximately parallel with the adjacent face of the cradle.

The saddle 10 is provided at its center with a longitudinally extending transversely curved seat 11, for receiving the pipe, the upper face of the said seat being shaped to it the insulating covering of the pipe.

Near each end of the seat, a transversely extending ,key block 12 is provided, the upper face of each of said blocks being curved to fit the periphery of the pipe, and the said hey blocks are of a depth to extend through the insulating covering into contact with the pipe itself.

At each side the cradle is provided with a depending rib 13, and each of the ribs is provided with a lateral outwardly extending flange 14:, for engaging beneath the flange 9 ofthe rib 8 of the cradle.

The under face of the saddleproper is provided with a series of transverse extending teeth 15., the said teeth corresponding in size and arrangement to the teeth of the series 3. The said teeth extend between the ribs 13, and a toothed roller 16 is arranged between the saddle and the cradle, the teeth of the roller meshing with the teeth 3 of the cradle and with the teeth of the saddle.

The roller is of a length to extend from near one side wall a of the pocket to near the other side wall, and the ribs 13 are spaced apart from each other a distance'corresponding to the spacing of the side walls 4i of the pocket. The roller is of such length that there will be a clearance between each end of the same and the ribs 13 or the side walls 4 of the cradle.

The saddle may be disengaged fi'om the cradle by moving it longitudinally until the flanges 14c are disengaged from the flanges 9 of the cradle. It will be noted from an inspection of Fig. 2 that the flanges 1d are of lesser length than the ribs 13, so that it is not necessary to move the saddle the full length of the cradle in order to disengage the flanges.

The key blocks 12 are of sufiicient length to prevent rolling of the pipe from ed the said blocks, thus preventing bruising or crushing of the insulating covering. At each end of each of the blocks, the seat 12 of the saddle is provided with a recess or depression 17, and at the inner end of each of the recesses ordepressions the saddle is slotted as indicated at 18.

Whenthe pipe is in place on the seat of the saddle, the insulating covering engages the upper face of the seat, while the p1pe rests upon the upper faces of the key blocks. The pipe is connected to the saddle by means of bands (not shown), which pass through the slots 18 and bind the saddle to the pipe.

in the use of the improved support, the cradle is placed in the conduit, the fingers 6 resting in the notches of the supporting ribs, and a scaling medium as for instance, ce-' meat or the like, is placed in the pockets, the pockets preferably having grooves registering with the grooves 8 of the supporting fingers.

The sealing medium thus enters the grooves and locks the cradle to the conduit. The saddle is connected with the cradle by moving the saddle longitudinally of the cradle to engage the flanges 14: below the flanges 9. The pipe is placed and held to the saddle by the bands.

lVhile the saddle may move longitudinally freely within limits with respect to the cradle, it cannot move laterally nor upwardly. The cradle is preferably slotted longitudinally of the pocket, and at the center thereof as indicated at 19, to permit foreign matters to escape from the pocket. The opening extends through the teeth, thus dividing the teeth 3 into two series.

The improved saddle is in a single piece, having keepers, the flanges 14, for engaging the cradle to prevent upward movement of the saddle. The key blocks 12 are preferably cast integral with the saddle. The saddle may be entered from either end of the cradle.

When the saddle is in register as regards length with the cradle, the roller may be at the center of the two series of teeth. After the pipe is laid, the saddle Will move with the pipe to compensate for expansion and contraction, thus preventing any buckling or lateral bending of the supported pipe.

ll claim 1. In a pipe support comprisin a cradle for ngaging a conduit and a saddle for engaging the pipe to be supported, and the roller arranged between the saddle and the cradle, the saddle, the cradle and the roller having interengaging teeth extending transversely of the length of the pipe to be supported for permitting the saddle to move longitudinally of the cradle, of ribs on the cradle at each side thereof and extending upwardly alongside the saddle at each side thereof and having internally extending flanges, and depending ribs at the sides of the saddle depending below the flanges of the cradle and having outwardly extending ribs intermediate their ends for engaging the ribs of the cradle.

2. In a pipe support comprising a cradle for engaging a conduit and a saddle for engaging the pipe to be supported, and the roller arranged between the saddle and the cradle, the saddle, the cradle and the roller having interengaging teeth extending trans versely of the length of the pipe to be sup ported for permitting the saddle to move longitudinally of the cradle, of ribs on the cradle at each side thereof and extending upwardly alongside the saddle at each side thereof and having internally extending flanges. and depending ribs at the sides of the saddle depending below the llangcs of the cradle and having outwardly extending ribs for engaging the ribs of the cradle.

3.
