Abstract
In a preferred embodiment, a crimping tool to crimp a cylindrical ring about cylindrical plastic pipe, including: first and second handles operative to open and close first and second jaws, respectively, pivotally attached, respectively, to proximal ends of the first and second handles and to each other; and the first and second jaws being toothless and defining therebetween, when the first and second jaws are closed, a cylindrical opening, the cylindrical opening to crimp the cylindrical ing about the cylindrical plastic pipe, and to produce a tight seal between the cylindrical plastic pipe, and to produce a tight seal between the cylindrical plastic pipe and a cylindrical substrate over which the cylindrical plastic pipe is inserted. A method of using the crimping tool is provided, as is using the crimping tool as a crimping gauge.
Description
- The present invention relates to crimping tools generally and, more particularly, but not by way of limitation, to a novel crimping tool for plastic pipe connectors and method of use thereof, the tool having toothless jaws. Also provided is such a tool that can be used to gauge whether crimps have been properly made.
- The present invention is concerned with crimping, typically although not necessarily, copper alloy metallic rings around polyethylene plastic pipe to attach the pipe to metallic fittings. The fillings may be tee fittings or coupling fittings, for example. Such plastic pipe has become more and more used in construction, as it is relatively inexpensive and much more inexpensive to install.
- A disadvantage of conventional crimping tools is that the jaws thereof are interlocking, with teeth at the top and bottom of one jaw in the opening defined by the jaws interfitting with complementarily shaped slots defined in the other jaw. As a consequence, the resulting marks and imperfections, or skiving and gouging of the crimped rings, caused by the interlocking teeth on the rings are unsightly.
- Furthermore, because the presence of interlocking teeth requires that the opening defined by the jaws be located a relatively large distance from the pivot points of the jaws, in order to increase the required mechanical advantage, a relatively high force is required to crimp the rings. Also, the presence of the interlocking teeth does not allow a great degree of freedom in skew of the pipe being crimped and the toothed jaws are likely to cause skewed crimped rings.
- Following crimping with a conventional tool, the degree of crimping of a ring is determined by gauging with a separate tool to make sure that the crimping ring has been crimped to an ASTM-specified diameter. The separate tool is typically a flat piece of metal having outwardly open, semi-circular openings defined therethrough, one pair of openings being provided for each size crimp to be gauged. One of the openings is a NO GO opening, meaning that, if a crimped ring can be inserted into the NO GO opening, then that crimped ring does not meet ASTM specifications for crimping because the crimp is undersized. If the ring can be inserted in the other of the openings, which is a GO opening, then the ASTM specification for crimping has been met, provided that the ring cannot be inserted into the NO GO opening. If the ring cannot be inserted into the GO opening, then the crimped ring does not meet the ASTM requirements for crimping because the crimp is oversized. While the separate tool is satisfactory, it does require that the separate tool be kept in the vicinity of the work, and is subject to be lost or misplaced. The separate tool also requires that the crimping tool be removed from the work area or set aside while the crimping ring is gauged.
- Accordingly, it is a principal object of the present invention to provide a crimping tool in which the jaws thereof are toothless.
- It is a further object of the invention to provide such a tool in which the pivots pins of the jaws defining the opening can be located farther away from the distal ends of the jaws, thus increasing mechanical advantage.
- It is an additional object of the invention to provide such a tool and method of use that require less crimping force.
- It is another object of the invention to provide such a tool and method of use that are economical.
- It is yet a further object of the invention to provide such a tool that can be used to gauge whether a crimping ring has been crimped sufficiently to meet required specifications.
- Other objects of the present invention, as well as particular features, elements, and advantages thereof, will be elucidated in, or be apparent from, the following description and the accompanying drawing figure.
- The present invention achieves the above objects, among others, by providing, in a preferred embodiment, a crimping tool to crimp a cylindrical rings about cylindrical plastic pipe, comprising: first and second handles operative to open and close first and second jaws, respectively, pivotally attached, respectively, to proximal ends of said first and second handles and to each other; and said first and second jaws being toothless and defining therebetween, when said first and second jaws are closed, a cylindrical opening, said cylindrical opening to crimp said cylindrical ring about said cylindrical plastic pipe, and to produce a tight seal between said cylindrical plastic pipe and a cylindrical substrate over which said cylindrical plastic pipe is inserted. A method of using said crimping tool is provided, as is using said crimping tool as a crimping gauge.
- Understanding of the present invention and the various aspects thereof will be facilitated by reference to the accompanying drawing figures, provided for purposes of illustration only and not intended to define the scope of the invention, on which:

-
FIG. 1 illustrates a crimping tool, constructed according to the present invention, and generally indicated by thereference numeral 20.Crimping tool 20 includes first andsecond handles pin 34. Pivotally connected, respectively, to handles 30 and 32 bypins toothless jaws toothless jaws link 50 extending betweenpins conventional ratchet mechanism 60 is disposed betweenhandles ratchet mechanism 60 is well known in the art, no further description thereof will be provided. A conventional adjustable linkage may also be provided in place ofratchet mechanism 60. Whencrimping tool 20 is in the closed position shown, first and secondtoothless jaws cylindrical opening 70. -
FIG. 2 illustrates a coupling fitting with which the crimping tool of the present invention may be used, the coupling being generally indicated by thereference numeral 100.Coupling fitting 100 includes twobarbs central portion 114. -
FIG. 3A illustrates the end of a length ofplastic pipe 120. -
FIG. 3B illustrates a cylindricalcopper alloy ring 130. -
FIG. 3C illustrates a tee fitting with which the crimping tool of the present invention may be used, the tee fitting being generally indicated by thereference numeral 140.Tee fitting 140 includes threebarbs central portion 148, as shown. -
FIG. 4 illustratesplastic pipes 120 inserted overbarbs rings 130 disposed therearound. It will be understood thatpipes 120 andrings 130 have been inserted overbarbs FIGS. 3A and 3B . The left side ofFIG. 4 shows crimpingring 130 uncrimped, while the right side ofFIG. 4 shows crimpingring 130 crimped. In the crimping process, the diameter ofcrimping ring 130 is decreased by about four to six percent and the length thereof is increased by about one and one-half to about five percent, to form a tight seal to be formed betweenplastic pipe 120 andbarb 146. The width of first and secondtoothless jaws crimping ring 130. -
FIG. 5 illustratescrimping ring 130 inserted overplastic pipe 120, the latter having been inserted overbarb 146, withcrimping tool 20 in an open position and havingjaws -
FIG. 6 illustrates that first and secondtoothless jaws ring 130 aboutplastic pipe 120. It will be noted fromFIG. 6 thatsmooth surfaces smooth surfaces FIG. 1 ) are in abutting relationship and that the opening defined by the jaws is substantially cylindrical.Smooth surfaces smooth surfaces tool 20 first forms crimping ring into an oval shape and then into a circular shape. Unsightly marks and imperfections, or skiving and gouging, on the outer periphery of crimpingring 130 are thus eliminated or minimized, resulting in a more professional appearance. - Although not apparent from inspection of
FIGS. 5 and 6 ,pipe 120 can be skewed as much as 15 percent from the axis of opening 70 andtool 20 will compensate for this skew by straightening out the pipe and producing a tight seal, a feature not possible with conventional toothed jaws that tend to produce a skewed crimped crimpingring 130. - Comparing crimping tool 20 (
FIG. 1 ) with the conventional crimping tools shown in the Catalog Brochure titled SARGENT QUALITY TOOLS—PROFESSIONAL PLUMBING TOOLS, by Rostra Tool Company, Branford, Conn., it can be seen that opening 70 and pivot pins 52 and 54 are located substantially closer together on crimpingtool 20 than are the like elements on the conventional crimping tools. For a ½ crimpingtool 20, this distance is about 2.8-3.0 centimeters versus about 3.5 centimeters for a conventional crimping tool. This placement means that mechanical advantage can be increased with crimpingtool 20 and the crimping force is reduced by about 15-20 percent. The crimping force, for example, required by a ½″ tool constructed according to the present invention is about 60 to 70 pounds applied 1-¾″ from the distal ends ofhandles - Crimping
tool 20 minimizes distortion of crimpingrings 130 not crimping accurately 90° perpendicular to the pipe and fitting axes. Cold working of crimpedrings 130 is achieved without the resistance in the tooth and valley areas of conventional toothed jaws. Because of the increased mechanical advantage,tool 20 can be made lighter than conventional toothed crimping tools and, therefore, user fatigue is minimized and productivity is improved. - Referring now to
FIG. 7 , there is illustrated an alternative embodiment of crimping tool 20 (FIG. 1 ), this embodiment indicated generally by thereference numeral 20′. Elements of crimpingtool 20′ having the same or similar functions as elements of crimpingtool 20′ are given primed reference numerals. For a description of the functions of the foregoing elements of crimpingtool 20′, reference should be made to the previous drawing figures. - Crimping
tool 20′ includes aset screw 200 threadingly inserted through firsttoothless jaw 44′, thedistal end 202 of setscrew 200 bearing against the inside surface of secondtoothless jaw 46′ to limit the distance apart first and secondtoothless jaws 44′ and 46′ can be opened. Setscrew 200 is thus used to adjust distance “A” between, respectively,smooth surfaces 160′ and 162′ of first and secondtoothless jaws 44′ and 46′ when the first and second toothless jaws are opened fully. This distance is set to the ASTM specification for crimped rings of the size for which crimpingtool 20′ is designed. Thus, crimpingtool 20′ can be used to pass over crimped crimpingring 130 to verify that the crimping ring has been crimped to the proper diameter. Thus, crimpingtool 20′ acts as a crimp gauge, eliminating inspection with an independent tool. Such would be difficult, if not impossible, with toothed jaws. - Reference first primarily to
FIGS. 3A-3C , in use, crimpingring 130 is slid overplastic pipe 120. Then,plastic pipe 120 is pushed overbarb 142 and the crimpingring 130 is positioned to approximately the middle of the barb. Then, crimping tool 20 (FIG. 5 ) is opened and moved over crimpingring 130. Then, crimping tool 20 (FIG. 6 ) is fully closed so thatsmooth surfaces smooth surfaces ring 130 is gauged to make sure that the crimping step has been done properly. If tool crimping 20′ is employed, that tool itself is used to verify that the crimping step has been done properly. - Although various sizes of crimping tools 20 (
FIG. 1 ) and 20′ (FIG. 7 ) may be provided, the crimping tools may be sized to accommodate crimpingrings 130 for pipe sizes ⅜″, ½″, ⅝″, ¾″, 1″, and 1-¼″, for example. - In the embodiments of the present invention described above, it will be recognized that individual elements and/or features thereof are not necessarily limited to a particular embodiment but, where applicable, are interchangeable and can be used in any selected embodiment even though such may not be specifically shown.
- Spatially orienting terms such as “above”, “below”, “upper”, “lower”, “inner”, “outer”, “inwardly”, “outwardly”, “vertical”, “horizontal”, and the like, when used herein, refer to the positions of the respective elements shown on the accompanying drawing figures and the present invention is not necessarily limited to such positions.
- It will thus be seen that the objects set forth above, among those elucidated in, or made apparent from, the preceding description, are efficiently attained and, since certain changes may be made in the above construction and method without departing from the scope of the invention, it is intended that all matter contained in the above description or shown on the accompanying drawing figures shall be interpreted as illustrative only and not in a limiting sense.
- It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention that, as a matter of language, might be said to fall therebetween.
