I PIPE-CLAMP.

Specification of Letters Patent.

Patented Sept. 19, 1905.

I Application filed March 11, 1905. Serial No. 249.663-

To all whom it may concern:

c it known that I, OLAUS S. AUGENSEN, a

citizen of the United States, residing at Chicage: in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pi pe-Glamps; and I do herer pipe-clamps, and more particularly has refer-- by declare the following to be a' full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Improvements in ence to clamps of that character designed for .repairing or closing breaks in bursted pipes.

The object of the present invention is the provision of a pipe-clamp the construction ofwhich is such as to enable its expeditious application to bursted pipes when occasion arises for. its use and whereby when so applied the clamp will serve to draw together the portions of the pipe adjacent the split or section of a pipe.

break therein, thus effectually sealing the split and preventing leakage through the bursted portion.

The invention further aims to provide a pipe-clamp which is so constructed as to render the same applicable to pipe-coils and in congested spaces wherein the attachment of repair-clamps of the ordinary type is-exceedingly diflicult.

With these general objects in view and others, which will appear as the nature of the improvements is better understood, the in-- vention consists, substantially, in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawings,and pointed out in the appended claim.

In theaccompanying drawings, Figure 1 is a perspective view of a-pipe-clamp constructed in. accordance with the present invention and illustrated in applied position upon a Fig. 2 is a top plan view thereof. Fig. -3 is a side elevation of the clamp. Fig. 4 is a transverse sectional view on the line 4: 4, Fig. 2.

Referring to the drawings, it will be seenthat the herein-described clamp comprises a pair of complemental sections 1 and 2, each of which is semicircular in cross-section, as clearly shown in Figs. 1 and 4., and designed to envelopa clamp when the sections are applied thereto. Obviously the sections 1- and 2 may be of .any desired length to fulfil the purposes of the invention and eflectually cover the ordinary split or break in a pipe,,

opposite and when'under pressure, as will presently appear, serve 'to bind against the pipe and firmly clamp the same.-

As before premised, the present invention aims to provide a clamp of such construction aswill enable its speedy application and also 5 permit it being used in congested spaces where the attachment of a repair-clamp of theordinary type is exceedingly difficult, and to the accomplishment of these ends the sections 1 and 2 are constructed to interlock at one of their edges,'but which will enable their ready assemblage and separation to permit application and removal of each section independ- A ently of theother. The section 1 therefore is, provided with a laterally-projecting rib 3, Which extends longitudinally of the body of said section, said rib being deflected at a slight angle to the body of the section, and thereby forming a longitudinal groove 4' between the free edge of the rib and the adjacent side of the body of the section. The rib 3 is designed to enter and lie within a longitudinal socket or recess 5, formed upon the section 2 at the edge of the same which lies contiguous to the edge of the section 1, upon which the rib 3 is 5 located, and said socket or recess is formed by a flange 6, which is a prolongation of the edgeof the body of the section 2', said flange being curved to assume substantially semicircular configuration in cross-section, but 9 having its free edge terminating at a point in -rear of the adjacent edge of the body of the section 2. By this construction it will be observed that a space is provided between the free edge of the flange 6'and the pipe to which the section 2 is applied, thus enabling the'rib 3 of the section 1 to be readily-inserted into the recess 5 when assembling the sections of the clamp upon a pipe. It will also berobserved that the inner side of the free edge of the flange 6 is a flat surface and lies parallel with the contiguousedge of the body of the section 2. By this construction the free edge of the flange 6 will 'enter the groove 4 in assembling the sections, as clearly shown by 5 IIO To hold the sections 1 and 2 upon the pipe when applied thereto, said sections are provided at the edges opposite to those upon which the rib 3 andflange 6 are formed with a plurality of perforated lugs 7, the lugs of .one section being coincident with the lugs of the other, and fitted in said lugs is a plurality correspondingly-shaped necks of the bolts 8,

' and thus hold said bolts against rotation when applying-thenuts 9, and the outer surfaces of the sections adjacent to said lugs 7 are also cut away, as at 10, to permit the heads of the bolts 8 and the nuts 9 seating upon the re spective lugs.

In use when a pipe has split, the section 2 is preferably first applied to the pipe at a point adjacent to the leak or split, and with a strip of packing 11 to serve as a patch placed over the split or break the section 1 is connected to the section 2 by inserting its rib 3 into the socket or recess 5 of the flange 6, whereupon the bolts 8 are passed through the coincident lugs 7 and the nuts 9 applied to the bolts. As

the pressure of the bolts and nuts is exerted upon-the lugs 7 the sections are drawn closely together, thereby firmly pressing the pack-' ing 11 upon the split portion of the-pipe, and,

3 obviously, as the pressure continues the packing is tightly clamped to the splitor broken portion of the pipe and leakage effectually stopped. In congested spaces, where the ordinary repair-clamp is difficult of application,

the section 1 may be readily applied to the section 2 by introducing one end of the rib 3 into the socket or recess 5, and by sliding the section 1 longitudinally of the section 2 it is obvious that the same will be positioned upon 4 the section 2' in order to register fully therewith and firmly hold the packing over the split or bursted portion of the pipe. The interlocking feature referred to also enables the ready application and separation of the sections of the clamp independently of each other,

be ,used for pipe-saddles. a

Having thus described theinvention, What is claimed as new, and desired to be secured by Letters Patent, is

A pipe-clamp, comprising a pair of complemental sections adapted for separate and independent application to and removal from a pipe, and designed to envelop the latter, one

of said sectionshaving at one of its edges a laterally-projecting longitudinally-extending rib, the other sectionhaving a flange at one of its edges, said flange forming a socket or recess extending longitudinally of said section and adapted to receive the rib of the firstmentioned section to interlock the sections, the free edgeof said flange terminating at a point in rear of the adjacent edge of the body of the section upon which it is formed, whereby a space is provided between the free edge of said flange and the pipe to which the clamp is applied to permit the insertion of the rib of the first-mentioned section into said socket or recess, a pl urality of perforated lugs formed upon theopposite edges of the sections, and a plurality of clamping-bolts arranged in said lugs for holding the sections in clamped position upon the pipe.

In testimony whereof I aiflx my signature in the presence of two Witnesses,

OLAUS S. AUGENSEN.
