Definitions
- This invention relates to pliers for clamping band or ring-type clamps, such as hose clamps.
- the pliers are adapted for use with hose and other clamps having an outward bulge or offset portion adapted to be pinched by the pliers 'to contract and shorten the main band or ring,
- the pliers of the present invention include a backup plate which is so positioned as to engage the outward face of the clamp offset or bulge when the pliers are closed to contract the main band, thereby to prevent the bulge from expanding outward into a loop.
- the backup plate is in the form of a thrust platform which, as the jaws of the pliers are closed to contract the band, is cammed inwardly toward the axial center of the band clamp, forcing the bulge or offset into a generally Keystone shape, thereby giving increased strength to the bulge as compared with an ordinary loop.
- the backup plate or thrust platform is made adjustable, so that when fully cammed into its most inward position, the platform occupies one of two (or more) limit positions.
- FIG. 1 is a front elevation of one form of the new pliers, showing the pliers in fully-closed position;
- FIG. 2 is a side elevation of the pliers looking in from the right in FIG. 1;
- FIG. 3 is a rear elevational view of the pliers of FIG. 1;
- FIG. 4 is a top view of the pliers of FIG. 1;
- FIG. 5 is a view in section taken along the line V-V of FIG. 1, looking in the direction of the arrows and showing the eccentric thrust pin inthe upper position, used when clamping larger-diameter clamps, as in FIGS. and 11;
- FIG. 6 is a sectional view similar to FIG. 5 but showing the eccentric thrust pin in its lower position, used when clamping small-diameter clamps, as in FIGS. 12 and 13;
- FIG. 7 is a perspective view of the thrust platform and the eccentric pin
- FIGS. 8 and 9 are perspective views, broken away, of the jaw ends of the lever arms of the pliers of FIG. 1;
- FIGS. 10 and 11 are views, in front elevation as in FIG. 1 but with parts broken away and in section, illustrating the manner of use of the pliers of FIG. 1 in contracting a large-diameter ring, the eccentric pin being in its upper position as in FIG. 5;
- FIGS. 12 and 13 are views similar to FIGS. 10 and 11 but illustrating the use of the pliers of FIG. 1 on a smalldiameter ring, the eccentric pin being in its lower position, as in FIG. 6; I
- FIG. 14 is a front elevational view of a modified form of clamp pliers, showing the pliers closed;
- FIG. 18 is a top plan view, looking down along the line XIXXD( of FIG. 17, showing the pliers about to be used to contract the hose clamp;
- FIG. 19 is a top plan view similar to FIG. 18 showing the hose clamp contracted by the pliers.
- FIGS. 20 and 21 are perspective views showing the pin parts and backup plate of the pliers of FIGS. 14-19.
- Pivot pin 20 is preferably a bolt provided with a hexagonal head 23 and rectangular nut 26, for the reason that, in addition to its function as a pivot pin, the pin or bolt 20 also has the function of holding captive the backup plate or thrust platform 30 while allowing limited movement of the platform 30 in a vertical direction.
- the lever arms 21 and 22 of the pliers are provided at their lower ends with handle-forming extensions 27 and 28. At the upper or jaw end, the lever arms are turned over 90 (or approximately 90) forming the jaws 24 and 25, respectively.
- the inward edges of the jaws are beveled or wedge shaped, for engaging and compressing the bulge or offset portion of the clamp, in the manner illustrated in FIGS. 10, 11 and 12, 13.
- backup plate or thrust platform 30 is that of a yoke, most clearly seen in FIG. 7. As there seen, yoke 30 has a transverse portion 33 which forms the surface for taking the outward thrust of the bulge or offset portion of the clamp.
- Yoke 30 has a pair of legs 31 and 32 which depend from the platform surface 33. Each leg is provided with an elongated slot 38 and 39 adapted to receive the shank of the pivot pin 20. Slots 3% and 39 allow the yoke 30 to be moved up and down relative to the pivot pin 20 while held captive thereon by the head and nut of the pin. Above the slots 38 and 39, legs 31 and 32 are provided with square or rectangular holes 36, 37, for receiving the square or rectangular ends 62 and 63 of the eccentric thrust pin 60. The cylindrical shank 61 of thrust pin 69 is off-centered relative to the square ends 62 and 63. Ends-62 and 63 are provided with lateral holes 64 and 65, respectively, for receiving the hairpin retainers 66 and 67, respectively.
- Retainer holes 64 and 65 are located midway between the upper and lower surface of square ends 62 and 63, whereas the axial center of the shank 61 of the eccentric pin 60 is located either above or below the level of the holes 64, 65, depending upon the position in which the eccentric pin is inserted in the yoke 30.
- the shank 61 is illustrated in the high position. This is also the position of the eccentric pin in FIGS. 1, 2, 3, 5, l0, and 11.
- the eccentric pin 60 is in the low position.
- the yoke 30 When the pliers are in an open position to receive the offset of the clamp, as in FIG. 10, the yoke 30 is free to move up and down within a range limited by the length of the slots 38 and 39. As the pliers handles are compressed to draw the jaws closer together, the jaws 24,
- the shank 61 of the thrust pin 60 is forced upward by the camming action of the sloping sides of the recesses 71 and '72 and the thrust platform is urged up against the outer face of the offset 41, preventing it from bulging out into a loop.
- FIGS. 12 and 13 there is illustrated a clamp of somewhat different type having an offset portion 51.
- Clamp 50 is considerably smaller in diameter than clamp 40, and the radial dimension by which offset 51 projects beyond the circle of clamp 50 is considerably less than that by which offset 41 projects beyond the circle of clamp 40. Accordingly, it is desired to have the thrust platform 33 operate closer to the clamp circle. This is accomplished by the eccentric thrust pin 60.
- FIGS. 14-21 illustrate a simplified form of pliers in which the clamping edges of the jaws close together at the side, rather than at the top, and the backup plate is behind, rather than below, the clamping edges of the jaw.
- the backup plate 130 is slidably mounted on the jaws in a transverse position by means of elongated slots 131 and 132, thereby to allow for opening and closing of the jaws.
- the backup plate 130 is not adjustable for different size clamps, and the backup plate is not cammed toward the clamp offset or bulge, when the jaws of the pliers close.
- FIG. 20 is a perspective illustration of the backup plate 130 and the jaw parts 124 and 125, as seen from front.
- FIG. 21 is a rear perspective view of the jaw part 124.
- the backup plate 130, and the jaw parts 124 and 125 are secured to the front face of the upper end portions of the levers 121 and 122, as by bolts 134 and 135.
- the upper end portions of the levers 121 and 122 are flat and in alignment with each other, as seen in the side elevation of FIG. 15, and, as also seen in the top plan views of FIGS. 16, 18, and 19.
- the backup plate 130 is provided with elongated slots 131 and 132, clearly seen in FIG. 20, through which the bolts 134 and 135 pass. These slots allow the jaw end of the pliers to open and close.
- jaw parts 124 and 125 are provided with upper'and lower flanges, forming channels of a size to receive the backup plate 130.
- the U-shaped jaw parts 124 and 125 slide, in opposite directions, along the plate 130. This has the important advantage of keeping the forming edges of the jaw parts parallel at all times.
- FIGS. 17 and 18 depict the pliers about to compress the offset 151 of clamp 150, thereby to contract the clamp about the hose 152 and the pipe 182.
- the forming edges of the jaw parts 124 and 125 grab the offset portion 151 and compress it, as illustrated in FIGS. 18 and 19.
- the backup plate 130 prevents the offset portion 151 from expanding outwardly, and forces it to assume the desired Keystone shape.
- the backup plate 130 also maintains the forming edges of the jaw parts 124 and 125 in alignment as they close on the offset portion 151.
- Clamp pliers for contracting band clamps having an offset portion
- said pliers comprising a pair of complementary lever arms pivotally connected at an intermediate point by a pivot pin, said lever arms having at one end handle portions and at the other end complementary jaw portions characterized by opposing clamping edges adapted to be brought toward each other in abutting relation, and a backup plate mounted close to but spaced from the path of closing movement of said clamping edges for receiving the thrust of the offset portion of the clamp, the clamping edges of the jaw portions and the thrust-receiving surface of the backup plate lying in planes which are parallel to the plane of movement of the handle portions, said jaw portions comprising a pair of channel members having at opposing ends clamping edges extending toward each other, said backup plate comprising an elongated bar for receiving and guiding said channel members for maintaining said clamping edges in alignment.
