Application September 26, 1955, Serial No. 536,427

4 Claims. (Cl. 81--19) The present invention relates to improvements in a vise for supporting pipe during caulking. It consists of the combinations, constructions, and arrangement of parts as hereinafter described and claimed.

It is a well-known fact that each section of sewer or soil pipe is provided with an enlarged bell-shaped portion at one end thereof, into which an end of an adjacent section of pipe may be inserted to provide a joint. This joint is caulked by first pressing oakum, or other suitable caulking material, into the bell-shaped portion, and then pouring lead into the bell to complete a water-tight joint.

As the cardinal object of our invention, we provide a vise that is arranged to support a section of sewer pipe in vertical position with the hell-shaped portion projecting upwardly. Thereafter, a second section may be inserted into the rst, and the joint readily caulked by the plumber.

More specically described, We provide a vise that is adapted to beV secured to a Work bench so that its jaws will project beyond an edge of the bench. The projecting ends of the jaws have coacting saddles thereon, which are disposed to be positioned on opposite sides of a vertically-arranged sewer pipe. One of the jaws is movable relative to the other so as to grip the pipe therebev tween.

Another object is to provide a vise of the character described, which is designed in such a manner as to grip pipes that vary in exterior diameters from standard sizes.

Other objects and advantages will appear as the specification continues, and the novel features will be pointed out in the claims hereuntov appended.

y DRAWING For a better understanding of our invention, reference should be had to the accompanying drawing, forming part of this specification, in which:

Figure l is a top plan view of our vise, illustrating it as being mounted on a fragmentary portion of a work bench;

Figure 2 is a longitudinal multiplane sectional view taken along the line 2-2 of Figure 1; and

Figure 3 is a fragmentary elevation, the superstructure appearing as a transverse sectional View, as seen from the plane 3-3 of Figure 1.

While we have shown only the preferred form of our invention, it should be understood that Various changes, or modifications, may be made within the scope of the annexed claims without departing from the function thereof.

Detailed description Referring now to the drawings, it will be noted that we have provided a vise having xed and movable jaws A and B, respectively, which are mounted on a work bench C so as'to project horizontally beyond an edge 10 of the latter. For the purpose of mounting these jaws, a base member D is fastened to the edge portion of the bench, and an anchor bar E is fastened to the bench inwardly from the edge 10.

As vclearly shown in Figures 1 and 2, the base member D is fashioned from angle iron, with the vertical and horizontal flanges 11 and 12 being butted against the edge 10 and the top 14, respectively, of the work bench. Lag screws 15, or other suitable fastening means, may be utilized for securing the base member to the work bench. Likewise, the anchor bar has been disclosed as being fastened by lag screws 16 (or bolts) to the top 14 of the bench. The anchor bar E has been illustrated as being mounted in parallel relation with the base member D.

With respect to the fixed jaw A, its inner end 17 is rigidly secured to the anchor bar E, its intermediate portion 18 is fastened to the base member D, and its outer end 19 projects beyond the edge 10 of the work bench. Regarding the movable jaw B, its inner end 20 is pivotally attached by a pin 21 to the anchor bar E, its intermediate portion 22 is slidably guided by the base member D, and its outer end 23 projects beyond the bench edge 10.

Moreover, the base member D is provided with an upstanding flange 24, which is fashioned with a horizontallydisposed slot 25. The intermediate portion 22 of the movable jaw B extends through and is guided in its movement by the walls of this slot.

It will be observed that the projecting ends 19 and 23 of the jaws are provided with coacting saddles 26 thereon, which have gripping surfaces 27 disposed in confronting relation with one another so as to be positioned on opposite sides of a vertically-arranged sewer or soil pipe F interposed between the saddles. As shown, the saddles dene sections of cylinders. Each of these sections has vinner and outer lateral ends 28 and 29, respectively, the

former being disposed closer together than the latter. This arrangement will permit the pipe F to be inserted into the saddles between the outer ends 29, when the movable jaw is swung into the dot-dash line portion shown in Figure 1, while the inner ends 28 will serve to limit movement of the pipe towards the base member D.

For the purpose of operating the jaws, we have provided a jaw-actuating mechanism designated generally at G. In its structural features, this mechanism includes a lever handle 30, which has one end thereof swingably attached by a pivot pin 31 to a bracket 32. The latter is provided by a pair of lugs that are secured to the movable jaw B so as to move the latter. Also, a yoke 33 has one of its ends pivotally secured by a journal pin- 34 to the lever handle 30 intermediate the ends of the handle (see Figures l and 3). A rod 35 is connected to the other end of the yoke, and slidably extends through an aperture 36 fashioned in a flange 37. This ange is rigidly attached to the fixed jaw A.

It will be noted from Figures l and 3 that the rod 35 has its outer end projecting beyond the flange 37. At least one nut 38, and preferably two, are adjustably threaded on the projecting end of the rod 35. Moreover, a spring 39 encircles the rod, and is interposed between the ange 37 and the nut or nuts 38.

When the lever handle 30 is swung in one direction about its journal pin 31 for clamping the pipe F between the jaws, that is, into the position shown in Figure 3, the handle and the yoke 33 will constitute a self-locking toggle. However, upon swinging the handle 3l) in the opposite direction, as suggested by the arrow 40, the toggle will be unlocked; and, at the same time, a stop 41 on the rod 35 will abut the flange 37. As the plumber continues to move the handle 30 in the direction of the arrow 40, the movable jaw B will be moved away from the fixed jaw A, thus releasing the grip of the jaws on the pipe F.

It will be appreciated, of course, that the exterior diameters of the pipe sections will vary from standard sizes.

3 Accordingly, the spring 39 has been provided so that it will yield, when the jaw B is brought up against the pipe F, and it is necessary to move the handle 30still farther in ordert'o iockthe toggle. ylt is quite obviousthatthe lengths of the jawsA'andB may be modied'soithat vises maybe provided that will'a'ccominodateepipesof diierent diameters.

Sumiitary of operation Assuming that our vise jaws A and l B are mounted on the work bench C so as tofproject lbeyond the edge of the latter,'as illustrated in Figures 1 and 2, the operation of thevise is summarized briefly as follows:

As the Vfirst step, the plumber should swing the lever handle in the direction ofthev arrow 40 (see Figure 3), therebyswinging the movable jaw B intro the dot-dash line position shown in Figure 1 At vthis time, the outer lateral ends 29 ofthe coacting saddles 26fwill be spaced a suicient distance to permit the section F of sewer or s oil pipe to be inserted therebetween, with its bell-shaped portion 42 facing upwardly (see Figure 2).

Subsequently, the lever handle 30 should be swung yinto the full-line position, asshown in Figures land 3, with the gripping surfaces 27 of the saddles 26 firmly engaging with the pipe section As willbe apparent from Figure 3, the lever handle 30 and the yoke 33 will constitute a locked toggle at this time.

Now the plumber may insert the lower end 43 of a second section F2 of sewer or soil pipe into the bell-shaped portion 42 ofthe rst section. In following the usual practice of caulking joints, an annular layer/i4 of oakurn, or other caulking material, should be inserted into the bellshaped portion 42 so as to surround the lower end 43 of the second section of pipe. When vthis has been accomplished, a layer of molten lead 45 should be added above the oakum, thus completing the caulked joint when the lead hardens.

Upon swinging the lever handle 30 in the direction of the arrow (see Figure 3), the movable jaw B will be swung away from the fixed jaw A, thus releasing the grip of the saddles 26 on the pipe section F. This will permit the caulked sections of the sewer or soil pipe to be removed from the vise.
