No. 427,497. Patented May 6, 1890.
UNITED STATES PATENT OFFICE.
IVILLIAM A. BERNARD, OF NEWr YORK, N. Y., ASSIGNOR TO BERNARD, VALKER & RICE, OF SAME PLACE.
PUNCH.
SPECIFICATION forming part of Letters Patent No. 427,497, dated May 6, 1890.
Application tiled October 18, 1889. Serial No. 327,429. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM A. BERNARD, a citizen of the United States, residing in the city and State of New York, have invented an Improvement in Combined Pliers and Punches, of which the following is a specification.
This tool is especially adapted to leatherworkers and for lacing belts, also to bookbinders and jewelers and workers in sheet metal.
I Vmake use of parallel jaws adapted to grasping the belt, leather, or other article, and I combine with such pliers a movable punch having a parallel motion and die held by an arm extending' up from one of the jaws, and there is a gage between the jaw and the arm to regulate the distance from the edge of the belt or leather where the punch is made to perforate, so that in this one tool is combined pliers, the punch, and the gage, and the punch is removable so that a punch of different size can be inserted, or the punch can be removed, if desired, for rendering the pliers more convenient in use.
In the drawings, Figure l is an elevation, and
Fig. 2 is an end view, of the tool; and Fig. 3 is a section longitudinally through the jaws and arms.
The jaws A B are received between the cross-pieces of the sheet-metal-handle levers, in which C C are the handle portions, and D D the cross-pieces formed of the sheet metal and crossing each other in pairs and riveted together at 2, to form the pivots for the handle-levers, and at 3 are rivets or screws passing through the forward ends of the cross-- pieces and through the jaws and forming the forward fulcrum connecting the jaws A B with the handle-levers, and the rivets or.
screws 4 pass through the handle-levers and through slots in the rear portions of the jaws A B, and the distance between the pivots 2 and rivets or screws 3 and 4 is the same, or nearly so, in order that a parallel movement may be given to the jaws A B as the levers C C are open or closed.
In one jaw .A there is a longitudinal hole,
into which is received a contractile helical` spring E, one end of which is made as an eye for one of the screws or rivets 4E to pass through, and there is a hook or eye at the l A, is protect-ed from injury, and is a reliable device for opening the pliers after they have been pressed together in use.
Upon the jaw B, and formed therewith or permanently attached thereto, is the arm F, extending along and at the back of the jaw and parallel thereto and at a sufficient distance therefrom for the insertion of the leather or belt or other article through which the hole is to be punched, and at the outer end of this arm F is the removable die or counter 6, and through the jaws A B are transverse holes for the reception ot' the punch G, which punch has head 8, a screw-shank at 9, and a cutting end l0, and the points of this cutting end are adapted to the hole or recess in the removable die or counter G. The diameter of the screwshank'9 is to be as great as the largest-sized hole to be punched by the tool, and the hole in the jaw B corresponds in size to the'plain part of the shank 9, so that such shank is guided by the jaw B, and the screw upon the shank allows for the punch being removed when not required for use and for the insertion of another punch of the desired size and character, and in consequence of the jaws A and B opening and closing parallel the movement of the punch is in a straight line, and it is guided with certainty by the jaw B to the movable die or counter 6, andI remark that this movable die or counter 6 is screwed or otherwise secured into the hole at the end ofthe arm F, so that such die or counter is changed from time to time as the punch may be changed.
For perforating leather or rubber belts or similar articles, I prefer to make the cutting end lOof the punch with two projecting points between asemicircular or nearly semicircular groove out across the end of the punch, so that these points penetrate the leather or similar material and commence to cut gradually, and they remove the piece of material by pressing it through the hole in the counter-die 6. If the punch is to be adapted to the insertion IOO of eyelets, the end of the punch and the surface of the counter-die are to be formed in the usual manner for pressing up such eyelets after they have been inserted through the belt or other article receiving the same, and it will be apparent that if the punch G is unscrewed and removed from the jaws lthere is an unobstructed opening through adapted to pass in between the back of the jaw A and the inner side of the arm F, and to this gage a bar 12 is connected, and it passes back through ahole in the base of the arm F, adjacent to and in line with the back ofthe jaw B, so that the end of this bar 12 may be within the hollow portion of the sheet.-
metal handle, and there is a clamping-screw 13, for holding the bar l2 and gage Il in position when adjusted. This gage H serves to determine the distance from the edge of the belt or other article at. which the punch G perforates such article.
This tool is very convenient for perforating the ends of leather or of belts for the reception of the lacing. Itis to be understood that the sheet-metal handles are pressed up within dies and the metal is to be of sufficient thicknessto furnish the required strength, and usually such sheet metal will be steel, and it can be pressed up to shapein either a hot or cold condition, the blank having previously been cut out by dies, and there is veryl belt, sheet of metal, or other article can be at a greater distance from the edge than the distance from the fulcrum to the punch. This is a great convenience, because in most handpunches heretofore made the holes cannot be punched at a greater distance from the edge than the distance from the punch to the fulcrum. l
A hollow punch can be used. in the same way as a solid punch, and the head 8 of the punch can be used as a hammer, if desired,`
and for sheet metal and similar material the punch should have a iat end.
I claim as my inventionl. The combination, with the sheet-metalhandle levers having cross-pieces united together at 2, of the jaws A B, the rivets or.
ing the same to the lever-handles, the jaw B,
having an arm F formed with or connected `to it and extending along the back of the jaw, Vand a punch G, passing transversely through the parallel-moving jaws and a counter-die in the end of the arm, against which the punch acts, substantially as set forth.`
c 3. The jawB and its arm F, in combination `with` the jaw- A, the handle-levers having `cross-pieces pivoted together at each side of @the jaws andpivoted to the jaws, so ,that the y@jaws move parallel, the punch G, removably connected to the jaw A and passing through and guided bythe `parallel-moving jaw B, "and acting against the counter-die at the end fof the arm F, substantially as set forth.
4f. The combination, with the parallel-moving jaws A B and arm F, permanently-connected with the jaw B, of` the lever-handles and connecting rivets or screws for giving to the jaws a parallel movement, the removable punch G, screwed into the jaw A and passing through and guided by the jaw B, and a gage I-I between the arm Fand the `jaw B, substantially as set` forth.
5. The combination, with the lever-handles having cross-pieces pivoted together, of the parallel-moving jaws A B and the connecting rivets or screws, the arm F, formed with or permanently connected to the jaw B, the gage I-I, and bar 12, the latter passing through the hole in the base of the arm and extendingwithin the hollow portion of the leverhandles, and a screw 13 for clamping the bar and gage, substantially as set forth.
6. The parallel-moving jaws A B andarm F, formed withor permanently connected to one of the jaws, aremovablepunch G, passing transversely through the parallel-moving jaws and screwed into one jaw and guided by the other jaw, substantially as set forth, and the lever-handles pivoted together and to the parallel-moving jaws, and also giving motion to the jaws andy punch, substantially as.- set forth.
Signedby me this 14th day of October, 1889.
WILLIAM A. BERNARD.
