Abstract

The tool has two mutually spaced jaws (10, 11) which are interconnected for movement relative to one another and each of which is intended to embrace a selected one of the two tubular members (14, 15). One jaw (11), is provided with a movable clamp (23), at the end of each leg of the jaw, connected to a hand-grip (18), which serves as a lever, by means of a link (21). Movement of the lever in the direction A operate the clamps and then pulls the pipe 14 towards pipe 15. <IMAGE>

Description

SPECIFICATION A tool for bringing two heavy tubular members into communicating abutment with one another The present invention relates to a tool for bringing two heavy tubular members into mutually communicating abutment with one another.
When laying sewage pipes, heavy drainage pipes and similar tubular members, there is normally used in the initial laying stages a lifting device of some kind or the other, by means of which the pipes etc., can be placed in alignment, one behind the other, whereafter the pipes are sealingly joined end to end.
The task of bringing two pipes together, so that they can fit sealingly one within the other, can be a heavy and difficult one, and is normally effected manually with the aid of an iron bar, crowbar or like implement, without much precision.
A prime object of the invention is to provide a tool by means of which two pipes lying end to end can be joined together in a quick and ready fashion and with greater precision.
Accordingly, this invention consists in a tool for bringing two tubular members which lie adjacent or nearly adjacent one another into communicating abutment with each other, said tool comprising two substantially U-shaped, mutually spaced gripping jaws which are slidably connected together and which are arranged to embrace partially said two tubular members, each of the U-shaped legs of one of said jaws having arranged on respective ends movable clamping means arranged to bear against a first of the two tubular members, wherein each clamping means is provided with a link which pivotally connects said clamping means to a respective free end of a U-shaped hand grip which functions as a lever and which can be swung about two mutually opposing pins arranged on a respective leg of the other jaw, said pins lying in a plane extending parallel with the movement plane of said clamping means, the arrangement being such that when a first force is applied to the closed end of the hand-grip, during a first phase of the movement of said hand-grip the clamping means are brought into clamping engagement with the first tubular member, and that during the subsequent application of a second force to the hand-grip, during a second phase of its movement, the first tubular member is brought against the second tubular member, which second tubular member serves as an aligning means and as an anvil or dolly means while the tool is in function.
Preferably the jaws are interconnected by means of a plurality of piston-cylinder devices.
In accordance with a further development of the tool, the movable clamping means are excentrically mounted for rotary or pivotal movement on the ends of the U-shaped jaws. The clamping means may also be provided with friction-enhancing clamping surfaces.
So that the invention may be more understood and further features thereof made apparent, an embodiment of the invention will now be described in detail with reference to the accompanying drawing, in which: Figure 1 is a perspective view of a tool constructed in accordance with the invention, and shows in broken lines two mutually adjacent tubular members lying end to end, and Figure 2 illustrates a clamping jaw incorporated in the tool shown in Figure 1.
The illustrated tool comprises two, mutually spaced U-shaped jaws, 10, 11 which are interconnected at their respective upper portions by means of a first connecting means in the form of a plurality of piston-cylinder jaws 12, 13, the pistons of which are fixedly welded to the jaws 10. The distance a between the ends of the jaws 10, 11 is the same, or approximately the same for both jaws 10, 11 and corresponds roughly to the diameter or external measurements of the pipes, indicated at 14,15to be brought together by means of the tool.
Fixedly welded to each of the mutually opposing surfaces of one of the jaws, jaw 10 in the illustrated embodiment, is a hollow rod 16 which co-acts with a respective pin 17, to pivotally support a U-shaped hand-grip 18.
The ends 19 and 20 of the legs of the hand-grip 18 have arranged therein bores into which a respective bent end of a rod 21 is inserted and locked in position by means of a split-pin or like device 22. The other end of the rod 21 is also bent, and is inserted into an excentricallyjournalled clamping means 23, through a bore located therein. The arrangement just described forms a second connecting means, which interconnects the jaws at the bottom positions thereof.
The clamping means 23 have a surface which is provided with friction enhancing means.
When using the tool to bring the facing ends of two mutually sequential pipes together, each of the jaws 10, 11 is placed around a selected one of the two pipes 14, 15. The pipe to be moved into the other is embraced by the jaw 11. By moving the hand-grip in the direction of arrow A, the clamping surfaces of the excentrically, pivotably mounted clamping means 23 are brought into engagement with the outer, cylindrical surface of the pipe, while holding the pipe firm and steady. The jaw 10, which grasps the outer pipe 15, acts as an aligning means and as an anvil or dolly. As movement of the hand-grip 18 continues, it acts as a lever and forces the pipe 14 towards the pipe 15. Because the jaw 10 functions as a dolly or anvil, the pipe moved by the action of the hand-grip is automatically brought into alignment with the other pipe, any small, lateral deviation in the alignment being accounted for automatically when the pipes are brought together.
Each jaw of the illustrated embodiment is provided with a U-shaped handle 24, for removing the tool.
Although the invention has been described and illustrated with reference to a particular embodiment, modifications can be made within the scope of the invention as defined in the accompanying claims.
As will be seen from Figure 1, the jaw 10 of the illustrated embodiment is larger than the jaw 11, which improvesthefunction of the jaw 10 as a dolly or anvil, and the ends of the jaws are somewhat curved.

Claims (5)

1. Atool for bringing two tubular members which lie adjacent, or nearly adjacent one another, in end-to-end relationship, into communicating abutment with one another, said tool comprising two substantially U-shaped, mutually spaced gripping jaws which are slidably connected together and which are arranged to embrace partially a respective one of said two tubular members each of the U-shaped legs of one of said jaws having arranged on respective ends movable clamping means arranged to bear against a first of the two tubular members, wherein each clamping means is provided with a link which pivotally connects said clamping means to a respective free end of a U-shaped hand grip which functions as a lever and which can be swung about two mutually opposing pins arranged on a respective leg of the other jaw, said pins lying in a plane extending parallel with the movement plane of said clamping means, the arrangement being such that when a first force is applied to the closed end of the hand-grip, during a first phase of the movement of said hand-grip, the clamping means are brought into clamping engagement with the first tubular member and that during the subsequent application of a second force to the hand-grip, during a second phase of its movement, the first tubular member is brought against the second member, said second member serving as an aligning means and as an anvil or dolly means while the tool is in function.
2. A tool according to Claim 1, wherein the jaws are movably connected together by means of a plurality of piston-cylinder devices.
3. A tool according to Claim 1,wherein the movable clamping means are eccentrically arranged for pivotal movement on the ends of the U-shaped legs of said jaws.
