Specification of Letters Patent.
' Patented July 30, 1907.
Application filed February 12, 1907. Serial No. 357,083.
To all whom it may concern:
Be it known that I, AUGUSTUS E. DURNER, a citizen of the United States, residing at Evansville, in the county of Rock and State of Wisconsin, have invented a new and useful Combined Punch and Shear, of which the following is a specification.
This invention relates to improvements in a combined punch and shear, and the object of the invention is to provide a structure of this kind that is simple in design, convenient, powerful, and durable in operation.
The invention consists in the novel construction,
combination and arrangement of parts hereinafter fully described and claimed and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a combined punch and shear constructed in accordance with the invention. Fig. 2 is an end elevation of the same, partly in section. Fig. 3 is a vertical longitudinal section on line 33 of Fig. 2. Fig. 4 is a transverse section on the line 4-4 of Fig. 3.
Corresponding parts in the several figures are indicated throughout by similar characters of reference.
Referring to the drawings, it is seen that the device comprises broadly a vertical, substantially rectangular hollow frame 1, recessed transversely and parallel to one end thereof to form the punch jaws 2, 3, and also having a transverse V-shaped recess above the jaw recess forming the shear jaws 4, 5, and moving parts within, and carried by, the frame to effect the punching and cutting of metal.
Between the punch jaws 2, 3 is rotatably supported by a vertical shaft the die plate 6 having a series of radially extending bifurcated arms 7, each arm being provided in its upper half with an aperture 8 adapted to receive and guide a punch and in its lower half with a corresponding die 9, the several arms containing various sizes of dies and being adapted to be rotated, as desired, into operative position.
The frame 1 is provided with an oblong transverse aperture 10 extending nearly the full width thereof near and parallel to the top edge of the frame, and the upper and lower edges of the aperture are provided upon each side of the frame with gear teeth forming two pairs of oppositely disposed parallel racks 11, 11 and 12, 12. Between the two upper racks 11, His arranged a downwardly facing horizontal track 13. Arranged within the aperture 10 are the two transverse rollers 1415, one being superimposed upon the other and each roller being provided at each end with pinions 16 adapted to engage in its adjoining rack and with the corresponding pinion upon the other roller. The lower roller 15 is provided with extended ends 17 adapted to receive a crank whereby the roller may be revolved, causing it to advance along its racks and to carry with it the superimposed roller. Any upward pressure upon the lower roller tends to press the upper roller against the said downwardly facing track 13 which prevents the lower roller from being lifted out of engagement with its racks and maintains the gears always at proper working distances from each other and from their respective racks.
Slidably housed within the frame 1 of the device and between the rack aperture and the punch jaw recess is the tool head 18 having a downward extension 19 back of the jaw recess. This head extends the full width of the rack aperture and is formed with an oblique upper edge that is held always in engagement with the lower roller by means of the spiral spring 20 which is secured at its upper end to the frame in a recess provided therefor and at its other end to the lower end of the downward extension of the tool head. It is now evident that by rolling the rollers back and forth over their racks, the cutter plate will be reciprocated longitudinally'within its housing. The forward under side of the cutter plate is provided with a socket 21 for receiving punches of various diameters adapted to cooperate with the corresponding dies of the die plate; and the forward edge of the cutter plate is notched to correspond with the shear jaws 4 and 5 so that when the cutter plate is at its highest position, the notch in the plate will register with the shear recess in the frame. The upper side of the notch in the cutter plate is provided with a hardened steel removable blade or cutter 22 and the opposing face of the frame is provided with a corresponding hardened steel cutter 23. It is now evident that as the rollers are rotated forward, the cutter plate is forced downward with a powerful action to simultaneously punch and shear metal introduced into the proper spaces and as the rollers are rotated rearward, the cutter plate is forced upwardly by the spring.
Having thus fully described the invention, what is claimed and desired to be secured by Letters Patent,
In a combined punching and shearing machine, a frame having punching and shearing recesses arranged one above the other, said frame being provided at the top with an oblong transversely extending aperture, upper and lower pairs of spaced horizontally disposed racks on the upper and lower walls of said aperture, the racks of each pair being spaced from each other and arranged near the opposite side walls of the frame, a stationary roller track disposed between the raeks of the upper pair, the frame being open to form a guiding opening between the racks of the lower pair, a tool head mounted in the guiding opening and having its upper end in the form of an inclined roller track, a pair of rollers, the intermediate portions of which are smooth and cylindrical for contact with each other, the upper roller engaging the stationary roller track, and the lower roller engaging; the inclined roller track of the toolhead, the ends of such rollers being provided with gears that inter-mesh with each other and with all of the 10 racks, a shear blade, and a punch carried by the tool head,
and cooperating blade and die members supported by the frame adjacent the recesses thereof.
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
AUGUSTUS E. DURNER.
