Abstract

A pliers for inserting the ends of hoses onto hose fittings. The pliers include a first set of jaws adapted to engage the fitting, a second set of jaws for grasping the end of a hose, and handles which are movable in a pincer action to force the end of the hose over the end of the fitting. The fitting jaws are spring biased to adapt to fittings of varying sizes. The hose engaging jaws lock in place on the hose to facilitate assembly of hose and fitting.

Claims

1. A push-on hose pliers for assembling hose and hose fittings which comprises:

(A) a first jaw assembly adapted to engage a hose fitting and comprised of;

(1) a fixed jaw member rigidly supported at one end of a first elongated handle,

(2) a pivoted movable fitting jaw member cooperatively associated with said fixed jaw member,

(3) face-to-face arcuate fitting-grasping jaw recesses in said fixed and movable jaw members to grasp the body of a hose fitting, and

(4) spring biasing means urging the jaw members together,

(B) a second jaw assembly comprised of a pair of relatively movable jaw members adapted to squeezably engage a hose to be pushed onto said fitting spaced from the end of the hose, said second jaw assembly being supported at one end of a second elongated handle, the centers of the jaws of said jaw assemblies being in approximately longitudinal alignment, and

(C) a pivotal connection between said handles spaced from the jaw assemblies, whereby, in a pincer movement, the jaw assemblies are moved toward one another upon movement toward one another of the opposite ends of the handles.

2. A push-on hose pliers according to claim 1 wherein said second jaw assembly comprises:

(A) a fixed hose engaging jaw member rigidly supported at one end of a cam link movably attached to the end of said second handle, the opposite end of said cam link being pivotally attached to said first handle and being the pivotal connection between said handles,

(B) a movable hose engaging jaw member pivotally connected to and associated with said fixed jaw for clamping a hose therebetween, and

(C) a movable jaw actuator connected between said movable jaw member and the end of said second handle for moving said movable jaw member responsive to longitudinal movement of said second handle.

3. A push-on hose pliers according to claim 2 wherein said cam link includes an elongated slot and said second handle includes a pin engageable and slideable within said slot.

4. A push-on hose pliers according to claim 3 wherein said cam link slot includes a locking recess at its end adjacent to the fixed jaw member, whereby the jaws may be clamped in closed configuration.

5. A push-on hose pliers according to claim 2 wherein said jaw actuator comprises a link pivotally connected at one end to said movable jaw and pivotally connected at the opposite end adjacent to the end of said second handle.

6. A push-on hose pliers according to claim 5 wherein the pivot axes of said movable fitting jaw member, said movable hose engaging jaw member and the connection between the jaw actuator and movable hose engaging jaw member extend in one direction, and the pivot axes of the connection between the cam link and the first handle and the connection between the jaw actuator and the end of the second handle extend in a direction displaced 90°

from the first.

7. A push-on hose pliers according to claim 2 wherein said hose engaging jaw members have generally flat face-to-face hose engaging surfaces.

8. A push-on hose pliers for assembling hose and hose fittings which comprises:

(A) a first jaw assembly adapted to engage a hose fitting, said first jaw assembly being supported at one end of a first elongated handle, said first jaw assembly comprising;

(1) a fixed fitting jaw member rigidly supported on said first handle,

(2) a pivoted movable fitting jaw member cooperatively associated with said fixed jaw member,

(3) face-to-face arcuate fitting grasping jaw recesses in said fixed and movable jaw members to grasp the body of a hose fitting, and

(4) spring biasing means urging the jaw members together, and

(B) a second jaw assembly adapted to engage a hose to be pushed onto said fitting spaced from the end of the hose, said second jaw assembly being supported at one end of a second elongated handle and comprising;

(1) a fixed generally flat faced hose engaging jaw member rigidly supported at one end of a cam link, movably connected to the end of said second handle, the opposite end of said cam link being pivotally attached to said first handle and forming a pivotal connection between said handles for pincer movement between the handles, said cam link including

(a) an elongated slot engageable with a pin carried by said second handle and slideable within said slot, and

(b) a locking recess at the end of the slot adjacent to the fixed jaw member and engageable by said pin,

(2) a movable generally flat faced hose engaging jaw member pivotally connected to and associated with said fixed jaw member for clamping a hose therebetween, and

(3) a movable jaw actuator for moving said movable jaw member responsive to longitudinal movement of said second handle and comprising a link pivotally connected at one end to said movable jaw and pivotally connected at the opposite end adjacent to the end of said second handle.

9. A push-on hose pliers according to claim 8 wherein the pivot axes of said movable fitting jaw member, said movable hose engaging jaw member and the connection between the jaw actuator and movable hose engaging jaw member extend in one direction, and the pivot axes of the connection between the cam link and the first handle and the connnection between the jaw actuator and the end of the second handle extend in a direction displaced 90°

from the first.
