CLAMPING SPANNER WRENCH Filed Nov; 6, 1956 INVENTOR MEDFORD W PAULSON,
his Alla/nay.
United States Patent CLAMPING SPANNER WRENCH Medford W. Paulson, Virginia, Minn. Application November 6, 1956, Serial No. 620,615
1 Claim. (Cl. 81-90) The present invention relates generally to wrenches and more particularly to an improved clamping spanner wrench especially suitable for tightening or loosening jet piercer burner tips.
Among the objects of the invention is to provide a wrench of the spanner type which can be used for manipulating fittings such as burner tips.
It is another object of the invention to provide a spanner wrench which may be used for removing burner tips quickly and easily without the danger of distorting the shape of the tip or damaging the surface thereof.
It is another object of the invention to provide a spanner wrench having a hinged clamp element and a lever pivoted to the clamp whereby the clamp can be quickly locked in gripping position around a burner tip or other circular fitting.
It is a further object of the invention to provide a spanner wrench which is inexpensive to manufacture, simple in construction and sufiiciently rugged to withstand distortion during the use thereof.
These and other objects will become more apparent after referring to the following specification and attached drawings, in which:
Figure 1 is a side elevation assembly view;
Figure 2 is a top view; and
Figure 3 is a view similar to Figure 1 showing the wrench partially open.
Referring more particularly to the drawings, reference numeral 2 designates generally the hinged clamp of the wrench of the invention. Clamp 2 is formed by two split rings 4 and 6 pivoted together at one end as at 8. Rings 4 and 6 are provided with opposed contact faces 10 and 12, respectively, at their free ends and 7, respectively adapted to engage each other when the rings are pivoted toward each other.
A pair of flange plates 14 is fixedly mounted, preferably by welding, on the free end 5 of the split ring 4. The flange plates 14 overlie the contact face and extend longitudinally thereof radially from the ring 4 in parallel spaced relation to each other. A lever-handle 18 is pivotally mounted intermediate its ends between the flange plates 14 adjacent their distal ends 20 by means of a pivot pin 24.
As shown in Figure 1, the end 22 of the lever 18 is adapted to engage the rear surface of the free end 7 of the split ring 6 to lock the two split rings together with faces 10 and 12 engaged when the lever is pivoted about pivot pin 24 on the plate 14.
Opposed spanner projections 26 and 28 extend from the inner peripheries of split rings 4 and 6, respectively. The projections are preferably removable so that the wrench may be used without them if desired. The end of projection 26 is tapered away from the inner periphery of the ring 4 in the direction toward the free end 5. The purpose of the tapered construction will become apparent hereinafter.
A handle 30 in the form of a ring or eyelet is affixed to the inner ring 6 adjacent-its free end 7 so as to facilitate manipulation of the ring.
The free end 5 of the split ring 4 extends beyond the free end of the split ring 6 and projects angularly so as to form a continuation of contact face 10 for engaging the outer edge 11 of the free end 7 when the rings 4 and 6 are pivoted toward each other.
In operation, the split ring 6 is positioned around the periphery of the burner tip W with the projection 28 inserted in one of the openings X in the circumference of the burner tip. Then the split ring 4 is placed around the other side of the burner tip while split ring 6 is held in position with handle ring 30. When the split ring 4 is placed in position the tapered end of the projection 26 is inserted into an opening Y in the circumference of the burner tip opposed to opening X. The tapered.
construction of projection 26 facilitates its insertion into the hole Y while the inner ring 6 is in position. After the rings 4 and 6 have been placed in position the lever 18 is pivoted on pivot 24 to move the end 22 of the lever 18 into engagement with the outer edge of the free end 7 and thus lock the two split rings together as shown in Figure 1. After the split rings have been locked in position around the burner tip, force is exerted on the lever to turn the burner tip clockwise as shown in Figure 1. If it is desired to turn the burner counterclockwise the wrench of the invention is turned over before it is positioned on the burner tip.
To remove the wrench from the burner tip it is merely necessary to pivot the end 22 of the lever away from the free end 7 and then disengage the split rings from the circumference of the burner tip by pivoting them away from each other.
While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claim.
I claim:
A spanner wrench comprising first and second split ring members pivotally joined together at one end to form a hinged clamp, opposed contact faces on the free ends of said split ring members engaging each other when said split ring members are pivoted toward each other, a pair of opposed flange plates on the free end of said first split ring member, said flange plates overlying the contact face on said first split ring member and extending longitudinally thereof radially beyond the free end of said first split ring member in spaced parallel relation to each other, a lever pivotally mounted intermediate its ends between said flange plates, one end of said lever engaging the free end of said second split ring member to lock said split ring members together with said opposed contact faces engaging each other when the lever is rotated on its pivot, a pair of opposed spanner projections each extending radially beyond the inner periphery of each of said split ring members, one of said projections being tapered in the direction away from its respective inner surface toward the flange plates.
