SEGMENTAL CLAMPING BODY.

Application filed June' i,

To all whom it may concern:

Be in known that we, JOSIAH Soo'rr and ALFRED A. BENNETT, citizens of the United States, and residents oi Toledo, in the county of Lucas and State of Ohio, have made an Invcnti 011 Appertaining to a Segmental Clamping Body, which invention is fully set "forth in the following specification.

Our invention has for its object to provide a means for clamping a body to a member wherein. the clamping means may be readily concealed. it thus has for its object to provide a means for clamping decorative bodies to supl'iorting parts or to parts of constructions, such as that oi a building. The construction embodying the invention is particularlydesigned so that the bodies containing the invention may be readily placed around a part of a construction or men'iber in the construction as distinctirom placing the part of the member through the body. The invention thus provides a means Whereby the body may be readily placed in position after the structurehas been formed or the part or member has been placed in position. It is particularly advantageous Where the part or member is fixed in the construction, that is, not easily removable, and it is impossible or ditficult to place the part or member through the body and secure the body in position relative to the part or member. The invention also provides a means whereby the body may be readily removed or replaced as may be desired. The innnediate object of the invention is to provide a means whereby decorative bodies may be readily secured around pipes in a building, such as the fli'iuges commonly located about risers, that is, pipes that pass from floor to floor to supply a heating medium. The invention is of particular advantage where the floors are formed or finished with cement or stone or terra cot-ta or other porcellaneous or earthy material. Thus the flanges or other decorative bodies may be formed of a cement or porcellaneous material that will match the material and color of the floor or oi the ceiling. Thus the decorative bodies may be formed of the same material as the floor or the color of the decorative bodies may be such as to add to the decorative cifect of the room and hence it may be colored any color desired.

The invention may be contained in bodies of different forms that may be secured to 1923. Serial No. 643,322.

parts or members for different shapes. To illustrate a practical application of the invention we have selected a collar of the conventional shape commonly used for covering the cracks or openings formed about riser pipes used. in buildings. The structure selected as an example of structures contain ing the invention is described hereafter and illust 'ated in the accompanying drawings.

Figure 1 of the drawings illustrates a side view of a collar and a pipe. Fig. 2 illustrates the manner in which the collar is placed in position and clamped to the pipe. Fig. 3 is a top view of the collar, showing it in position about the pipe. Fig. 4 a sectional view taken on the line a i indicated in Fig. 1. Fig. 5 is a vertical sectional view taken on the line 5-5 indicated in Fig.

In Figs. 1, 2, 3 and 5, the floor or ceiling is indicated conventionally by the part marked 1. A pipe 2 is shown extending through the floor around which the flange or collar 3 is placed.

The collar 3 is formed in segments, preterably in two semi-circular parts that substantially fit the pipe 2. The collar 3 may be formed of any earthy material, such as a cement mixture or a porcellaneous material and may be given any suitable color. It is so made as to substantially fit the pipe. In this connection it is to be noted that the pipes vary in size and ii the pipes are used for supplying steam or other heating medium throughout the building, they expand and contract according to the temperature to which they are subjected. Also the collars themselves may vary slightly in size since they but roughly approximate the size of the pipe. The means for attaching the parts to the pipe is such as to allow for the difference in the dimensions that may occur. Consequently one of the great advantages of the invention lies in the fact that the attaching means is so constructed that it may be readily applied to any pipe notwithstanding variations in size Within, of course, certain limitations. If the pipe is too small the ends of the semi-circular portions of the collar will abut and the opening formed between the portions will be too large for the pipe, while on the other hand if the pipe is too large for the collar one or both of the juxtaposed ends will be slightly spaced apart. The invention provides a means whereby each individual semi-circular portion is secured to the pipe so that the collar will be held in position, notwithstanding slight variation in sizes.

The under side of the collar is provided with a shallow recess at, and holes 5 extend from the bottom of the recess into the body of thecollar. A hole 5 is located in each semi-circular portion of the collar 3. Spring members, such as the elastic wires 6, commonly formed of brass, are curved so as to engage opposite sides of the pipe 2 and are bent so that one end of each wire may be located in a hole 5 and thus engage the col lar parts. The wires 6 are so shaped that to place the end portions 7 in the holes 5, the wire will be slightly distorted so that its elacticity will draw the semi-circular portions of the collar 3 against the pipe 2 or cause their ends to abut one against each other and to be thus held in position when they are placed about the pipe 2.

The edges of the shallow recess 4; are so formed or positioned that they will be located in close proximity to portions of the wires 6 and form abutting shoulders that will press against the wires 6 if the collar 3 is rotated about the pipe 2 in one direction. Rotation in the clockwise d'rection of the collar as will appear upon examination of Fig. l would cause the wires to unwind or slip from the pipe 2 if it were not for the engaging shoulders formed by the edge of the recess .t which abut against the wires 6 and cause the ends of the wires to slide around the pipe. Rotation of the collar counter-clockwise will cause the wires to slide around the pipe. Thus the collar will be held in position, notwithstanding rotation in either direction.

In order that the parts of the collar may be readily slid into position the wires may be provided with bent end portions 8 that slope away from the pipe when. they are placed in position about the pipe. The parts of the collar are then placed against the pipe and slightly tilted so as to cause the openings 5 to be placed over the sloping portions 8 of the wire. The ends of the wires will thus enter the openings 5 when the collars are crowded down into position and at the same time the wires 6 will be subjected to the distortion of the wedging action of the portions .of the collar between the openings 5 and the pipe, and thus the spring wires 2 will draw and hold the parts of the collar in position about the pipe 2 when the parts are pushed down so that they are located at right angles to the axis of the pipe.

lVe claim: v

1. In a segn'iental pipe collar, a pair of spring wires, each spring wire having a circular part surrounding in hook form more than one-half of the pipe and having an end portion extending parallel to the axis of the pipe, the collar segments having openings so located as to receive the portion of the spring extending parallel to the axis of the pipe when the springs are deformed to cause the springs to elastically draw the parts of the collar toward the pipe.

2. In a segmental pipe collar, a pair of spring wires, each spring wire having a circular part surrounding in hook form more than one-half of the pipe and having an end portion extending parallel to the axis of the pipe, the collar segments having openings so located as to receive the portlon of the spring extending parallel to the axis of the pipe when the springs are deformed to cause the springs to elast tically draw the parts of the collar toward the pipe, the bottoms of the segments having recesses for receiving the curved hook shaped parts of the springs.

In testimony whereof, we have hereunto signed our names to this specification.
