Pipe clamp

Claim 2

A clamp for a pipe joint comprising two parts, one of which comprises a substantially circular wire member having a hook at one end and a straight portion with a threaded tip at the other end, and the second of which comprises a coupling member of channel formation having a web and sidewalls, the sidewalls having arcuate edges to engage the pipe joint when the clamp is assembled thereon, the web having the hook engaged through one end of the web, and having the threaded tip of the straight portion engaged through the other end of the web, the straight portion being angled toward the hook at the point where it passes through the web whereby the point of tangency of the straight portion with the pipe joint is less than 90* from the web of the coupling member, and threaded nut means engaging said threaded tip to take up the wire member upon said joint with said opposite ends spaced from each other.

Claim 3

The clamp as claimed in claim 1 in which there are openings in the web at opposite ends thereof to accommodate said hook and straight portion, respectively.

Claim 4

The clamp as claimed in claim 2 in which there is an angled shoulder formed in the web and said shoulder is in the form of a boss embossed upwardly out of said web with the opening at that end of the web in the center of said boss.

Claim 5

The clamp as claimed in claim 1 in which there is an elongate slot in the said web and the hook engages one end of the slot while the straight portion passes through the other end of the slot.

Claim 6

The clamp as claimed in claim 4 in which there is an angled shoulder formed in the web and said shoulder is below the surface of the web at the said other end of the slot.

Claim 7

A clamp for a pipe joint comprising two parts, one of which comprises a substantially circular wire member having a hook at one end and a straight portion with a threaded tip at the other end, and the second of which comprises a coupling member of channel formation having a web and sidewalls, the sidewalls having arcuate edges to engage the pipe joint when the clamp is assembled thereon, the web having the hook engaged through one end of the web, and having the threaded tip of the straight portion engaged through the other end of the web, the straight portion being angled toward the hook at the point where it passes through the web whereby the point at which the straight portion is tangent to the pipe joint it is adapted to engage is less than 90* from the web of the coupling member, threaded nut means engaging said threaded tip to take up the wire member upon said joint and therE is an angled shoulder formed in the web at the point where the straight portion passes through said web, and during the taking up of the wire member, the nut means engages upon said angled shoulder.

Claim 8

A clamp for a pipe joint comprising two parts, one of which comprises a substantially circular wire member having a hook at one end and a straight portion with a threaded tip at the other end, and the second of which comprises a coupling member of channel formation having a web and sidewalls, the sidewalls having arcuate edges to engage the pipe joint when the clamp is assembled thereon, the web having the hook engaged through one end of the web, and having the threaded tip of the straight portion engaged through the other end of the web, the straight portion being angled toward the hook at the point where it passes through the web whereby the point at which the straight portion is tangent to the pipe joint it is adapted to engage is less than 90* from the web of the coupling member, threaded nut means engaging said threaded tip to take up the wire member upon said joint and therE is an angled shoulder formed in the web at the point where the straight portion passes through said web, and during the taking up of the wire member, the nut means engages upon said angled shoulder.

Claim 9

The clamp as claimed in claim 6 in which said shoulder is in the form of a boss, embossed upwardly out of said web.

Claim 10

The clamp as claimed in claim 6 in which said shoulder is below the surface of the web.

Claim 11

A clamp for clamping the pipes of a telescoped joint together, comprising two parts, one part consisting of a generally circular wire member having a hook formation at one end and a straight portion with a threaded tip at the other end, the wire member having an open side providing a space between the straight end and the hook formation which is somewhat less than 90* in extent, said space being closed by the second part which consists of a coupling member, the said coupling member comprising a channel formation having a web and lateral sidewalls, the lateral sidewalls having arcuate edges to follow the contours of the wire to form a circle therewith, the web of the coupling member having an opening at one end and the hook formation being engaged therein, and a second opening at the other end with the straight portion extending therethrough, the configuration of parts being such that the straight portion passes through the web at an angle other than 90* and is canted toward the hook formation, the web having an angled shoulder integral therewith at the second opening, there being threaded nut means engaged with the threaded top and bearing upon the shoulder when the clamp is being taken up to constrict the same upon said joint.

Claim 12

A clamp for clamping the pipes of a telescoped joint together, comprising two parts, one part consisting of a generally circular wire member having a hook formation at one end and a straight portion with a threaded tip at the other end, the wire member having an open side providing a space between the straight end and the hook formation which is somewhat less than 90* in extent, said space being closed by the second part which consists of a coupling member, the said coupling member comprising a channel formation having a web and lateral sidewalls, the lateral sidewalls having arcuate edges to follow the contours of the wire to form a circle therewith, the web of the coupling member having an opening at one end and the hook formation being engaged therein, and a second opening at the other end with the straight portion extending therethrough, the configuration of parts being such that the straight portion passes through the web at an angle other than 90* and is canted toward the hook formation, the web having an angled shoulder integral therewith at the second opening, there being threaded nut means engaged with the threaded top and bearing upon the shoulder when the clamp is being taken up to constrict the same upon said joint.

Claim 13

The clamp as claimed in claim 9 in which said angled shoulder is embossed from the surface of said web.

Claim 14

The clamp as claimed in claim 9 in which there is an enlarged triangular formation integral with said lateral sidewalls straddling said straight portion.
