Otto Kampfe, of New York, N. Y. Pocket Implement.
No. 899,407. Specification of Letters Patent. Patented Sept. 22, 1908.
Application filed May 28, 1907. Serial No. 376,104

To all whom it may concern:

Be it known that I, Otto Kampfe, a citizen of the United States, residing at the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Pocket Implements, of which the following is a specification.

My invention relates to a combination tool or handy implement particularly adapted for use by men both personally and in men's clubs and by means of which handy tool the lid of a cigar box may be opened by lifting the nail holding the same and then closed by driving the nail back to place. A cigar taken from the box may have one end cut off, the cap or stopper of a bottle may be removed and the cork thereof then pulled, and the implement may also be used as a pocket-knife.

In carrying out my invention, the case of the implement may be integral or made as the ordinary case of a pocket-knife, and said implement has alining holes made through the sides and a blade mounted in the case is adapted upon pressure to move across between these openings, forming a cigar cutter.

One or more blades are pivoted to the case at one end and occupy a recess in one side and a cork-screw is pivoted to the case at the opposite side and occupies a recess therein.

An arm device, or extension, is formed at one end of the handle or pivoted thereto; this is provided with a nail puller and hammer head and an engaging edge adapted to be brought in, contact with the edge of the metal cap of a bottle to remove the same. This latter arm device may bear a fixed or movable relation to the handle.

In the drawing, Figure 1 represents by an elevation a form of my invention with the parts thereof closed. Fig. 2 is a side-elevation of the same form of the invention, with the parts opened out. Fig. 3 is an elevation of a modified form of my invention, Fig. 4 is an elevation of the parts of the form shown in Fig. 3, the parts thereof opened out. Fig. 5 is a plan of the arm device of Fig. 4. Fig. 6 is a cross section at the dotted line x, x, of Fig. 4, and Fig. 7 represents the metal cap of a bottle and the relation thereto of the engaging device of Figs. 1 to 4 inclusive, as positioned for removing the same.

Referring particularly to Figs. 1 and 2, a represents a one-part handle, that is to say, a handle that is cut from a solid piece recessed for a blade d on one side and connected to the handle by a pivot 2; the handle being provided with alined holes c from under the cutting edge of the blade and with a recess on the opposite side of the blade for a cork-screw e. Said handle is also provided integrally with an extension or arm device f having on the free end nail puller jaws 3 with a hammer head at 4 and an engaging lip at 5.

Figs. 1 and 2 show the closed and open position of this form of my invention and Fig. 7 shows the arm device thereof as engaging the metal cap 6 of a bottle for the purpose of removing the same.

Referring, to the form of my invention shown in Figs. 3 and 4, b represents the two-part handle with alining holes c1. This handle is made similar to the usual handle of a pocket-knife. It is provided with a main blade d and a second blade d1 of smaller size, the holes c1 coming under the edge of the main blade d, both blades being connected to the handle by the pivot 2 and received in a unitary recess at one side of the handle. In the opposite side of the handle there is a recess receiving the cork-screw e which in this instance is pivoted to the handle, In this form of my invention the extension or arm device f1 is pivoted at one end of the handle and adapted to turn into the recess in the handle as shown in Fig. 3, or to turn out in the position for use as shown in Fig. 4; this arm device also being provided at its free end with a nail puller jaw 3, a hammer head 4 and an engaging lip 5.

For identity of function and substantial identity of structure the arm device f Figs. 1 and 2, and the arm device f1 Figs. 3 and 4, are constructed alike.

The nail puller jaws of Figs. 1 to 4 inclusive are constructed the same if viewed in a plan or edgewise of the handle as is the nail puller jaw device of the form of my invention shown in Fig. 5, therefore the same does not require further illustration.

In the operation of the cigar-cutter portion of the forms of my invention it will be apparent from Figs. 1 and 3, that if the unburned end of a cigar be passed into the alined holes c or c1 while the combination tool is held in the hand and a pressure is then applied to the blade to force the same down into the handle, that the blade will cut across the alined holes and so sever the end of the cigar and return to its normal position by the usual spring to be secured along the back of the handle.

In the form of my invention shown in Figs. 3 and 4, the arm device or extension f1 is shown by the cross section Fig. 6, as provided with an edge f3 forming the inner curved outline of this member. This edge is designed as a wire cutter for the wiring frequently employed in corked bottles for holding the corks in place. In use the tapering pointed and jaw end is forced beneath the wire, that is, between the wire and the bottle and the edge f3 brought under the wire where a movement with pressure will cut and break the wire.

In Fig. 7 I have shown a slightly modified form of implement handle and arrangement of implement.

I claim as my invention :—

1. The combination with a pocket knife handle, of a pivoted extension adapted to be turned into the recess of said handle or to be opened outwardly and having a shoulder to limit the pivotal movement in one direction when the handle is used as a lever, said extension having a curved portion formed at one termination into lifting claws, the portion nearer the pivot having an engaging lip extending into the concavity of the curved portion at its other termination, the reverse side of the curved portion serving as a fulcrum for the claws when the handle is used as a lever, and the claws serving as a fulcrum when said handle is used as a lever to operate the engaging lip.

2. The combination with a pocket knife handle, of a part forming an extension from one end of the handle, said extension having ® curved portion formed at one termination into lifting claws, the portion nearer the handle having an engaging lip extending into the concavity of the curved portion at its other termination, the reverse side of the curved portion serving as a fulcrum for the claws when the handle is used as a lever, and the claws serving as a fulcrum when the handle is used as a lever to operate the engaging lip.

Signed by me this 23rd day of May 1907.

Otto Kampfe.
