Application filed December 21,1906. Serial No. 348,912.
To all whom it 'nmy (3011100771,:
Be it known that 1, JAMES CLARK, a citizen of the United States, residing at Bradford, in the county of Mcliean and State of Pennsylvania, have invented certain new and useful Improvements in Clamping Rings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate two forms in which 1 have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.
The object of my said invention is to provide a clamping-ring for pipe-couplings formed of wrought metal and preferably of sheet metal, such as wrought iron or steel, which can be cheaply made and which will possess great strength and at the same time which may be made of comparatively light or thin material.
To this end the device is formed, preferably, of two parts and comprises a substan tially flat plate member, in which are located the bolt-holes, and an annular flange member, the plate member being provided with portions which are bent at an angle thereto to engage and reinforce the flange member and also to reinforce the plate member. The two members of the coupling are preferably formed separately and may be placed together and used, or they may be united by welding or brazing or in any other desired manner, or they may be formed integrally if preferred.
Referring to the drawings, Figure 1 represents a perspective view of the two members of the clamping-ring, showing them separated. Fig. 2 is a sectional view of the parts, showing them in operative relation. Fig. 3 is a plan view of the complete ring, partly broken away. Fig. 4 is aperspective view similar to Fig. 1, showing a modified form of clamping-ring embodying my invention. F ig. 5 is a sectional view of the ring shown in Fig. 4. Fig. (3 is a top plan view of the ring shown in Figs. 4. and 5, partly broken away. Fig. 7 is a partial sectional view similar to Fig. 6, showing a ring I similar to that shown in Figs. 4, 5, and 6,
but made in one piece.
in the form of my invention shown in Figs.
i 1 2, and 3, A represents the plate member of the clamping-ring, which consists of a substantially annular plate having projecting portions a extending outwardly at intervals 1 in the plane of the plate and provided with bolt-holes a of any desired shape. These t outwardly-extending portions are provided on each side with integral wings or lugs (1, which are bent substantially perpendicui larl'y to the plate member, as shown, thus forming reinforcing-lugs, which may be i termed struck-up lugs and which are preferably disposed radially with respect to the l central pipc-aperture a? of the plate memi ber. These reinforcing-lugs are thus disl posed in pairs, the lugs of each pair being arranged on opposite sides of a bolt-hole. Each of the lugs (15 has its inner edge a preferably straight and substantially perpendicular to the plane of the plate member A, and said lugs are preferably inclined or beveled on their outer edges, as shown, although this is not essential.
B represents the flange member, which consists of an annular portion disposed perconsists of an annular portion disposed substantially perpendicularly to the plane of the plate member and adapted to fit tightly between the inner faces or edges (0 of the reini forcing-lugs a, said annular portion having i at one end an inwardly bent or curved annu- 1 lar reinforcing-flange 1), adapted to engage the face of the plate member A, the inner edge of said flange 1) registering with the pipeaperture (1? in the plate member, as shown in Fig. 2, in which a pipe-section and connecting-bolts are indicated in dotted lines.
I it will thus be seen that when pressure is applied to the bolts the plate member is reinforced by the annular flange 1) and also by the lugs (1 a by reason of their engagement with the exterior of the flange member B, and, conversely, the flange member B is also reii'iforced by the portions of the plate mem- 1 her A, surrounding the central pipe-aperture,
and by the reinforcingdugs a a.
It will be noticed that the inner diameter of the main portion of flange member B is greater than that of the pipe-aperture a,
thus forming a packing-recess (indicated at i I), Fig. 2) for the reception of an annular ICO packing or packing-ring of rubber or other I "I; In Fig. 7 I have shown a partial sectional suitable material. view of another modification of my improved The two parts of the clamping-ring are clamping-ring in which the platesection, placed in engagement, as shown in Fig. 3, here indicated A and the flange member B and may be used in the manner therein illusare formed integrally by forging, rolling, or trated. by the use of suitable dies and have exactly If desired, the parts may be so fitted that the same form as that shown and described when the flange member B is placed in operwith reference to Figs. 4, 5, and 6. In this ative relation with the plate member A it 1 form of my invention the plate member is will be frictionally retained by the engagealso provided with the central pipe-aperture ment of the lugs a a with the exterior of the a the bolt-holes a the exterior reinforcflange member B. In some instances I find ingflange a, and reinforcing-lugs a. The it desirable to permanently unite the two i flange member B is formed by bending up parts by welding or brazing or otherwise. inner marginal portions of the plate member For example, I may weld the engaged faces l and then expanding it into the form shown, of the plate member A and the inturned f I so that the walls of the flange member shall flange I) along the plane indicated in Fig. 2
engage the lugs a a, the flange member at x as, and I may also weld the engaged porbeing bent outwardly sharply from the pipetions of the lugs a and the flange member B I along the lines y y, (indicated in Fig. 2,) if found desirable.
In the form of my invention shown in Figs. 4 to 6, inclusive, A represents the flat plate member, which in this instance consists of an annular plate having a central pipe-aperture a and having its outer edge portion bent on one side substantially perpendicularly to I form a reinforcing flange a; The plate member is also provided with a series of bolt- I holes a of any desired shape, located at in- I aperture a to form the reinforcing-flange E and provide the packing-recess If. The construction of the clamping-ring shown in Fig. 7 is identical with that shown in Figs. 4, 5, and 6 except that the members A and B are integral.
