United States Patent ADJUSTABLE JAW PLIER TYPE JAR OPENER Harley Lee Coggburn, Big Bear Lake, Calif.

Application May 18, 1955, Serial No. 509,261

1 Claim. (Cl. 813.44)

This invention relates to jar openers for containers having screw-type caps or 'lids.

It is an object of the present invention to provide a multiple purpose jar opener for jars having screw-type caps or lids and which is applicable to glass jars of any size as well as bottles of any size.

It is another object of the present invention to provide a jar opener of the above type which is adapted to be used in homes, restaurants, drug stores, hotels and hospitals, and which is sufficiently sturdy and strong to be used to tighten bolts or pipes of any size.

It is still another object of the present invention to provide a jar opener of the above type which may be adjusted to any size cap or lid merely by pushing on one handle and pulling on the other.

For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a perspective view of a preferred embodiment of the present invention shown in operative use in removing a screw type cover from a glass jar;

Fig. 2 is an enlarged horizontal sectional view thereof taken along the line 2--2 of Fig. 1;

Fig. 3 is a fragmentary enlarged vertical sectional view taken along the line 3-3 of Fig. 2;

Fig. 4 is a top plan view of the pivot portion of the device; and

Fig. 5 is a vertical sectional view thereof taken along the line 5--5 of Fig. 4.

Referring now more in detail to the drawing, indicates generally a handle integrally formed at the free end thereof with the arcuate portion 11 which terminates in a can opener 12, substantially as illustrated. The other end of the handle 10 is integrally formed with the arcuate portion 13 which is ofiset at 14 from the arcuate portion 15, the handle 10 being provided with an elongated slot 16 formed with the arcuate teeth 17 along one edge. It will be noted that the handle 10 is relatively straight intermediate the arcuate portion and the can opener 12. A second handle indicated generally at 18 is provided for cooperative use with a handle 10 and is integrally formed at one end with the bottle opener 19 and at the other end with an arcuate portion 20 having an arcuate slot 21 provided along one edge with the curved or arcuate teeth 22, the teeth 22 being on the opposite side as the teeth 17 of the handle 10. The arcuate portion 20 is integrally formed with the arcuate extension 23 which is in turn integrally formed with the vertically offset arcuate portion 24 along the offset portion 25.


A jaw 26 having an arcuate teeth edge 27 adapted to engage the screw-type cap 28 is provided with an opening within which the free end of the arcuate portion 13 of the handle 10 is pivotally mounted by means of a pin 29, the cap 28 being positioned on the glass jar 30. A second jaw 31 having the arcuate teethed surface 32 adapted to engage the other side of the cap 28 is provided with an opening 33 within which the free end of the arcuate portion 24 of handle 18 is pivotally mounted by means of a pin 34.

The handles 10 and 18 are pivotally connected by means of a pin 35 (Fig. 5) which passes through the grooves or slots 16 and 21, washers 36 and 37 being provided on opposite faces of the handles and retained on the pin by the peened ends 38 and 39, respectively. The pin 35 is of suflicient size to just pass through the grooves or slots 16 and 21 and upon rotating the handles together (Fig. 1), the teeth 22 and 17 will engage the opposite sides of the pin to pivot the handles and to draw the swivel jaws 31 and 26 together about the cap 28 in firm engagement therewith and to permit the easy removal of the same. Although nine teeth have been shown in each of the grooves 21 and 16, it will be readily apparent that any other number may be employed without departing from the spirit and scope of the invention. The olfset portions 14 and 25 permit the proper positioning of the swivel jaws 26 and 31 at the sides of the cap 28 relative to the pivot pin 35. These recessed offset portions will permit a better grip on the cap 28 by the swivel jaws 26 and 31.

To adjust the device to caps 28 of different diameter, it is only necessary to pull on one of the handles and pull on the other, as will be obvious. The curvature of the swivel jaws will permit the same to firmly embrace the cap when the handles 18 and 10 are not properly positioned relative to each other.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

A jar opener comprisinga first handle, a second handle, means pivotally interconnecting said handles adapted to permit longitudinal and curvilinear adjustment of said handles relative to each other about their pivot point, a pair of arcuate jaws pivotally connected to the free ends of said handles adapted to engage opposite sides of a screw-type cap, and arcuately offset portions at the free ends of said handles pivotally mounting said arcuate jaws, one of said handles having a relatively straight central portion having an elongated slot having teeth along one side thereof, the other of said handles including an arcuate portion having an arcuate slot having teeth along the other side thereof, said means comprising a pin passing through said slots, washers on opposite ends of said pin adjacent the outer faces of said handles, and means at the end of said pin for retaining said washers thereon.
