ADJUSTABLE CLAMP FOR PIPES.

Specification of Letters Patent.

Patented May 22, 1906.

invented a new and Improved Adjustable Clamp for Pipes, of which the following is a full, clear, and exact description.

My invention relates to certain improvepatent on a fastening device, No. 737,437, dated August 25, 1903.

The general purposes of my invention are similar to those accomplished by the appa ratus described in said patent. It can be applied to horizontal, vertical, or slanting walls and can be used with all kinds of pipes, for flag-poles and other devices which pass through walls. It is essentially an adjustable escutcheon. for roof vent-pipes or roof-flanges, but for many other purposes, such as to cover holes made by all kinds of pipes passing through Walls, and on steam-engine shafts to keep oil from running down the shafts. While it may assist in supporting a roof or other structure, it is chiefly designed to form a water tight joint .and to provide means for keeping the joint tight if the roof settles or if the pipe expands or contracts.

Further objects of the invention will appear below.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a device constructed in accordance with the principle of the. present invention. Fig. 2 is a sectional view of a similar device applied to a slanting roof. Fi 3 is a sectional view of another form of t e invention. Fig. 4 is a sectional view on the line 4 4 of Fig. 1. Fig. 5 is a perspective view of a detail. Fig. 6 is a sectional view showing a modification. Fig. 7 is a longitudinal sectional view showing another way in which my invention may be used. Fig. 8 is an elevation of a modification, and Fi s. 9, 10, and 11 are perspective views of mo ifications.

To protect a pipe a, I provide a band 6, having a collar portion 1), adapted to fit the pipe 0., and provided, if desired, with a pack- It can be used not alone portion which is provided with corrugations b These corrugations may eXtend around the band or may be applied vertically, as desired, in order to take up expansion and contraction and other movements of the pipe or supporting means. This band is open at one point and is designed to overlap.

In order to provide for using the band for different purposes, I index it, as shown by certain marks I). These marks are properly labeled, so as to show what kind of a pipe is intended to be employed. In the use of these indexes or marks the overlapping por tion of the pipe is brought up to the mark which is indicated to conform to the kind of pipe with which the device is to be used, and the parts are then clamped or tightened in position. For the purpose of securing the parts together a pair of brackets a are riveted to the band. One of these brackets is intended to receive a screw-threaded bolt (1, which may be straight or curved. This bolt may be provided with a nut e, as shown in Figs. 1 and 4, or the bolt may be headed on the outside of a flange c on the bracket. The other bracket is provided with an elongated slot 0 to allow for the movement of the bolt caused by the tightening of the band and for variations in the size of the pipe. Instead of a straight bolt a curved bolt may be employed.

When the band is used 011 a large pipe, I prefer to employ a lengthening and strengthening piece f. This piece is provided with two flangesf, through which the bolts pass, and in this case a bolt is mounted between each of these flanges and the flange of one of the portions 0. This strengthening-piece bears against the pipe or directly against the with nuts or heads, or they can be screwed in the threads in the flanges c and f, as shown in Fig. 6. The packing for the device may be of any desired kind or character and is indicated at gin Figs. 2, 3, and 7. It is made '11 the form of a washer of soft graphite or of a cement which remains elastic and allows the expansion and contraction of the parts. In Fig. 7 also I have shown a modified construc tion in which the band extends over the top of a funnel h, which is soldered to the roof. Between the band and funnel is formed a space which is filled by a wedgeshaped packing k, also formed of a washer of soft graphite or the like, as stated above.

The modification shown in Fig. 8 represents a band 6 formed with the other features specified above, and instead of being convex, as the other forms are, is made in the form of a cone.

In Fig. 9 I have shown another form of fastening device, in which a screw d is provided, with a flattened portion d riveted to the neck of the band. This screw is provided with a nut d in the ordinary manner, which can secure the screw to a bracket on the other side or to the lengthening-piece f. The lengthening-piece shown in Fig. 9 is provided with an open slot f 2 instead of a perforation.

In Figs. 10 and 11 I have illustrated two other forms of simple fastening devices which I can employ. In the former figure I slit the band or its neck on parallel lines and force out a projection b This leaves an opening 6 through which a bolt or screw from the other end of the band can be passed. In Fig. 11 a tongue I) is formed on the end of the band, and this is provided with a perforation b for the reception of a fastening device. All these features can be used in combination with the devices shown in the other figures.

In all of the forms of my invention the vertical seam, where the ends of the bandbcome together, is soldered, and the brackets are placed far enough apart to permit a soldering-tool to be inserted for this purpose.

This invention is designed to replace the old method which is now in usenamely, the cutting of the pipes having a hub, so that the hub will come even with the roof, and setting sheet-lead into the hub to secure it to another joint of pipe. tates waste of pipe, and the sheet-lead does not form a permanent or perfect oint. By the construction specified I form the device with a minimum amount of metal and allow for expansion and contraction in a most efficient manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A clamping device for pipes, comprising an adjustable band, a pair of brackets thereon, each having a perforated flange, one of the brackets being elongated, a lengthening and strengthening piece located between the brackets and bearing against the band, said lengthening-piece having perforations, and a bolt passing through the perforations of the strengthening-piece and a perforation of one of the said brackets.

2. In a clamping device for pipes, comprising a band passing around the pipe, a pair of brackets on the band, a strengthening-piece between the said brackets having perforated flanges at its ends and adapted to bear against the band, said strengthening piece being curved to conform substantially to the shape of the pipe, and means for adjustably securing the flanges of said strengthening-piece to the brackets.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
