Description
P 1937- v. BERNEVSSER 2,078,750
WRENCH Filed Feb. 6, 1936 INVENTOR.
Pin/cam TEER/VEFJER ATTORNEY.
Patented Apr. 27, 1937 UNITED STATES PATENT OFFICE 1 Claim.
My invention relates to screw wrenches.
The object of my invention is to provide an efiicient wrench by means of which jar tops of the screw type may be easily and quickly opened or securely closed.
A further object is to provide a construction that may be made at a very low cost by stamping and pressing operations, and that will be light in weight.
All of the parts may be made of sheet metal.
Referring to the drawings which form a part of the specifications;
Fig. 1 is a perspective view of a jar having a screw cap or top thereon, and a wrench embodying my invention afilxed to the cap in position to rotate the cap in either direction required to tighten or loosen it on the jar.
Fig. 2 is an inverted plan view of the wrench, the sleeve portion of the handle being shown in longitudinal section.
Fig. 3 is a cross sectional view taken on line 3-3 of Figure 2, showing the sleeve and shank portion of the handle in operative engagement.
Fig. 4 is a cross sectional view showing the sleeve and shank portions of the handle in disengaged relation.
IO indicates a fruit jar, and II the usual screw cap or top thereof.
In Figure 2, the broken circles illustrate caps of different diameters, showing the wrench in position to engage a top having either a small or large diameter.
l2 indicates the bar formed from a sheet of mild steel or other suitable material, and with the V-shaped jaw member formed integral therewith, its upper side I2 lying in a plane with the flat side of the bar I2, and having an end wall l5 which carries a V-shaped flange l6 which extends inwardly and is spaced from the upper side l2 a predetermined distance, as illustrated.
The inner edge of the flange I6 is preferably formed with teeth H as shown, arranged in a row on one or both sides of the V-shaped edges.
I3 indicates the sleeve portion of the handle, and [4 a sliding jaw portion.
The tubular sleeve is formed with threaded portions l8 -l8 respectively, located on opposite sides as shown, which engage with the threaded parts I 9l9 respectively, formed in the shank of the bar l2.
The jaw member I4 is free to slide on the bar, and is formed with teeth I4 carried on an ofiset portion I 4 as shown.
It will now be understood that the teeth are required on either one side of the V-shaped jaw 5 or on the sliding member i l, to prevent the wrench from slipping on the cap in the act of opening the jar, but I prefer to have them formed in all three of the edges mentioned, as shown in the drawing. 10
26 indicates a hook formed integral with the bar and located near the apex of the V, and is used to remove caps of the anchor type.
When the sleeve I3 is in the position relative to the bar as illustrated in Figure 4, the sleeve may freely slide on the bar until the sleeve is rotated to cause the threads to engage the threads of the bar, and thereafter, on rotating the sleeve, the member I4 is forced into locking engagement with the cap, as will be readily understood.
The construction as shown provides three sets of teeth, each set arranged in a straight row, each row extending at an angle to the other two rows, making an efiective wrench.
Having thus described my invention I claim as new:
A wrench of the character described consisting of three pieces, one of which comprises a flat bar portion having threads formed in its side a edges only, and having a V-shaped head formed on one end, said head being of substantially channel formation in cross-section defining upper and lower parallel walls continuing through the bight of the V-shaped head, and an outer end wall, the upper wall being integral with the fiat bar portion and the lower wall having its free edge presented for engagement with a jar cap with the uninterrupted intermediate portion of the lower wall acting to strengthen the end portions of the lower wall when the wrench is in service, a tubular handle portion having discontinuous threads formed therein adapted to engage with the threads on the bar in one position and to be disengaged therewith when in another position, and a jaw member carried on the bar in slidable relation between the inner end of the handle and the V-shaped head.
