HOUSEHOLD-TOOL.

Tooll 'whom it may concern:

' Be it known that I, Join: C. Fons'ma, of

1 the reverse, movement of the handle. in

V 'Pittsbur ,in the vcounty of Allegheny and State of enns'ylvania, have invented certain 5 new and useful Improvements in Household- Tools, of which the following is a specification. e

The invention provides a wrench for jar caps .of novel construction which is adapted :for use interchangeably in tightening and loosening the caps, with means holding the cap-embracing member normally open and re dy to beapplied'to a cap, said member a so serving as a ring for hanging the tool on a nailOr hook when not in use.

In the accompanying drawings, Figure 1 is a view in top plan of the improved tool, the wrenchbeing in normal position for embracing a jar cap. -Fi 2 is a section of the xtool on line 22 of F 1. Fig. 3 is a to its outer edge flanged downwardly at 3 to grip the cap A. The band is preferably provided with flat top portions 4 which are of decreasing width toward the center of the v band where it is relatively narrow, as indicated at 4'. This formation provides a gripping device of desirable resihenc without impairing its strength, and the at top portions provide surfaces for the handle connections.

A In the present ada. tation one extremity of handle 5 is flattene as shown and adjacent one edge is secured to one end of member 2 y ivot 6. F ed in the handle extremity is t e U-shaped s ot 7, the o posite extremi- "ties 7 7" of which are equa distances from pivot 6 and nearer thereto than the other portions of the slot, the latter being thus eccentric to pivot 6. Entered in the slot is pin 8 carried by the other extremity of member2. I

' The U-sha ed slot, in conjunction with pin 8, pro 'des a double cam connection, member 2 beingcontracted on the ca for unscrewing the same when the ban e is spammin 01 Letters Patent. Application filed December 18, 1909. Serial No. 588,414.

turned as in full lines of Fig. 3 with 'lot extremity 7 extended towar pin 8, while dotted lines in Fig. 3, contracts the pin for tightening the, cap, it being understood that by either use the requisite pressure for loosening or tightening the cap is applied to the handle in the direction in which the handle is moved for clamping member 2 thereon. The curvature of the slot proviches a cam connection which is much more effective and more nearly devoid of friction on pin 8 than is possible with a slot having straight lines.

The tongue-like rejection 9 tformed b theslot is provide at its extremit' wit, a depression 9' which is I engaged y pin 8, as in Fig. 1, and holdsthe contracted member 2 normally expanded ready to embrace the cap andwith the handle projecting straight out. Thus the device is always in position to be applied without making it necessary to manipulate it tab both hands rior to placing it on the cap, and the ringike member 2 ma: be convenientl used for hanging the too on a nail or hoo when not in service. 1

The tool handle is preferably formed of a' piece of plate-like by turning the longit dinal ed es upwardly as indicated at 0. The han 1c is slotted longitudinally at 11, and slidable on the top surface thereof between edges 10 is 4 the plate-like carrier 12, from which a can-cutting knife 13 projects through slot 11 as vi shown. The carrier is slidab y held on the handle by rivet 14 with head 14 at the under side of the handle adapted to bear on .the can top B,/as in Fig. 5, thus holding the handle properly spaced therefrom and forming a runner-like member which facilitates eta], and is reinforced rojection 16 extending m 1 6, in such use the handle bein reverse from the position shown in Fig. 5

and serving as a lever for the cap removing jacent each other, said memberhavin a top portion which bears on the top suriace ofthe cap with saidtop portion flanged downwardly to grip the side face of thecap,

' the end portions of said member being inflexible and its intermediate portion resilient, a handle pivoted to one end of the member, and a cam-slot and pm connection between the handle and the other end of the member.

2. The combination of a cap-embracing band of resilient contractile material, the band ,beingrcurved in ring-like form with the. ends thereof adjacent each other, a

' handle pivoted to one end of the band, a'

3. The combination of a cap-embracing member shaped from a single piece of metal with its ends adjacent each other, said member having flat top portions decreasing in width backwardly from said ends and also formed with a depending cap engaging flange, a handle pivoted to the fiat surface at one end of said member, and.a pin and slot connection between the handle and the fiat top surface of the other end of said member. 1

4. The combination of a. cap-embracing member formed of resilient contractile material and of ring-like form with its ends adjacent each other, a handle pivoted to one end of the member, the handle formed with a double cam-slot, both ends of the slot being nearer the handle pivot than the other portions of the slot the slot forming a tongue-like projection, the end of said projectlon being formed with a seat, and a pin carried by the other end of said member and entered in the slot and adapted to be 45 engiaged by said seatfor setting said capem raclng member in an expan ed inoperative position.

5. The combination of a cap-embracing member shaped from a single iece of metal with its endsadjacent each other, the metal being widest adjacent its ends and decreasin in width from said ends to form the resilient intermediate portion, a handle pivoted to one of said ends, and a cam-slot and pin connection between the handle and the other of said ends.. 1

6. The combination of -'a; cap-embracing member shaped from a single plece of metal with its ends adjacent each other, the metal belng widest ad acent its ends and decreasing 1n width from said ends to form the resilient intermediate ortion, a ca enga in flange depending om said embei handle pivoted to one'end of the member, and a cam slot and pin connection between the handleand the other end of the member.

'7. The combination of a contractile capembracing .member' adapted to expand for embracing a cap, means for setting the member in an ex anded and inoperative position, and means or contracting said member and causing it to grip the cap.

In testimony whereof I afix my signature inv presence of two witnesses.
