ADELORE JOSEPH LEVIS, OF HOUGHTON, MICHIGAN.

CUTTING AND PUNCHING TOOL.

Specification of Letters Patent.

Patented June 26, 1906.

To all whom it may concern:

Be it known that I, ADELORE JOSEPH LE- VIS, a citizen of the United States, and a resi-' dent of Houghton, in the county of Houghton and State of Michigan, have invented a new and improved Cutting and Punching Tool, of which the following is a full, clear, and exact description.

The invention relates to the cutting and punching of sheets and bars; and its object is to provi e a new and improved cutting and punching tool more especially designed for the use of tinners, plumbers, and other mechanics and arranged to permit of forming tongues and slots in the ends of stovepipesections to allow convenient interlocking of adjacent stovepipe-sections.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement as applied on a Stovepipe-section for cutting a tongue and a slot-therein, a portion of the Stovepipe being shown and in section. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of the cutter. Fig. 4 is a longitudinal sectional elevation of a stovepipe, showing adjacent sections interlocked; and Fig. 5 is a plan view of the ends of adjacent stovepi esections provided with a tongue and a s ot for interlocking purposes.

The parallel members A and A of the tool are pivotally connected with a pair of pivoted handles B and B, adapted to be taken hold of by the operator to impart a parallel motion tothe members A and A on closing On the member Aare removably secured a cutter C and a punch D, and in the top face of the member A is for ned a recess C, arranged directly opposite the cutter C, and in the said member A is also formed an aperture D in register with the punch D.

The cutter C is triangular in cross-section, and its bottom is inclined upwardly from the apex to the base, and the registering recess C is similarly shaped-that is, is made triangflar-and its bottom is inclined upwardly om the apex to the base, so as to fully regpipe-section F. On the member A is ad' justably secured a gage E by the use of a setscrew E or other suitable means, so as to gage the distance the aperture F is to be formed from one end of the section F of a stovepipe or other article to be provided with a slot. It is understood that the Stovepipesections F and F are provided at adjacent ends with a tongue F and slot F respectively, to permit convenient interlocking of the Stovepipe-sections by engaging the tongue F with the slot F, as plainly shown in Fig. 4f By the arrangement described it will be seen that the end of a Stovepipe-section can be readily passed between the members A and A, so that the'top of the member A restsagainst the inner face of the stovepipe-section, and consequently the member A forms an anvil. When the Stovepipesection F has been introduced or passed between the members A and A until the edge of the Stovepipe-section F abuts against the punch D and the handles B and B are pressed toward each other, then the member A moves toward the member A, and in doing so the cutter C cuts the material of the stove pipe-section F to roduce the triangular tongue F. When tlie other section F is inserted between the members A A until the outer edge of the section abuts against the gage E and the handles B B are pressed,

then the punch D shears the material of the- Stovepipe-section, so as to form the slot F By reference to Figs. 4 and 5 it will be seen that the tongue F and the slot F are in lonslot F is of a width slightly in excess of the thickness of the material and the length of the slot is somewhat in excess of the width of the tongue F at the base thereof. When the the two Stovepipe-sections F F are joined together, the tongue F can be readily engaged with the corresponding slots F so as to securely interlock the Stovepipe-sections,

'gitudinal alinement with each other, and the as will be readily understood by reference to Fig. 4..

The tool is very simple and durable in construction, is not liable to get easily outof order, and, if desired, the cutter C and the punch D may be readily removed from the member A for grinding purposes or to be replaced by new ones whenever it is desired to Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A cutting and punching tool comprising a pair of members, and means for moving the members parallel toward and from each other, one of the members carrying a cutter and apunch, the punch being arranged behind the cutter, and of greater length, where by to form a gage for the cutter, and the other member having a recess and an aperture for cooperating with the cutter and the punch, respectively.

2. A cuttin and punching tool comprising a pair of members, and means for moving the members parallel toward and from each other, one of the members carrying a cutter and a punch and the other member having a recess opposite the cutter and an aperture,

opposite the punch, the said cutter having a trian ular cross-section and a bottom inclined longitudinally and upwardly from the apex to the base.

3. A cuttin and punching tool comprising a pair of mem ers, and means for moving the members parallel toward and from each other, one of the members carrying a cutter and a punch and the other member having a recess opposite the cutter and an aperture opposite the punch, the said cutter having a opposite the punch, the said cutter having a trian ular cross-section and a bottom inclined longitudinally and upwardly from the apex to the base, the said recess corresponding in shape to the said cutter and the bottom of the recess being inclined upwardly from the base to the apex.

5. A cuttin and punching tool,comprising a pair of mem ers, and means for moving the members parallel toward and from each other, a cutting device and a punching'device arran ed in longitudinal alin'ement between sai with, the rear device being arranged to act as a gage for the front device.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ADELORE JOSEPH LEVIS.
