rIhe invention. relates toi punching cuttingl tools andI its object is. to; provide means whereby such` tools mayl be readily operated tomaike a. .out through material, such as cloth paper'or the like, or to; form, a snccessionof holesi.
The inventionconsists in the several novel features hereinafterset fort-la andj more pari ticularly defined by the claims; at. the con@ clusionhereof.,y L In the drawings: Fig. 1 is a vertical section of a 'device yembodying'the invention and equipped with aknife-blade for cutting slits. Fig..2 is a section taken on line 2 2 of Fig. 1. Fig. 3 is a section taken on line 3*-3 of Fig. ,1. Fig. 4 is a verticalsection i of a modified form of the invention, applied toa punch or perforating tool. Fig. is a perspective of thelsupporting base shown` in F 1g. 4. Y Fig. 6' is a section takenv onk hne` In Fig. l, there is shown a device for Iveradapted to lbe moved over Vthe work in order f to position the knifev where the slit is to beY made and to permit it to be readily moved from place to place to form slits at different places or a succession of conncctinff slits when desired. A pair ,of posts 9 are E y secured in the ring 8. Knife 7 is removably secured by screws 11 to a cross-head 10.l Ads jacent the outer ends of' the cross head, sleeves 12 are iixedly held in sockets adjacent the ends of the cross-heachand these sleeves are slidably mounted on the posts 9 tovertically guide the cross-head.` The upper ends of sleeves 12 are each closed by a screw-plug 13. Springs 1li are interposedA between the plugs and the upper ends of the' posts 9 respectively to retract or liftjthe cross-head and the cutter carried thereby. The ends, of the knife 7 rare preferably guided in grooves l5 -formed in the posts. y
A stem 18 has its lower end secured by a Vscrew 19 in a bushing 20'which is held in a socket in the cross-head l0, so thatthe stem will be rigid with the cross-head. Aweight ed hammer, consisting of a sleeve 21, which is slidably mounted on the stem 18, andga knob 22, which is screw-threaded to the' up'- per end yof. the sleeve, is adapted to impart a hammer blow tothe cross-head l0 to drive the knife 7 through the work. A spring 23,
coiled aroundstem 18`and heldin a socket in xedly sleevee2'1and-knobf23, engages a pin 24- fixed tol smid. stem. andy is` adapted to retractor lift the-hammer: after a blow has'beenimparted thereto., to drive-the cutter through the mate-- rial. vBushing 2OV is preferablygformedrof o0 i `hardy metaland serves as an anvilV to-receive the hammer blowfof the loweraend of 'the v sleeve 21.
.and itsown weight will tend to retain it in its assigned position. The operator will then` impart a blow or a succession of blows to the knob 22 and the impact of the hammer "against the bushing or anvil 2O will drive the Vknife 7 through the material. If a continu` ous cut is desired, the ring 8V may be moved relatively tothe jmaterial7 so thatthe slits formed in the work will connect with one another for this purpose. Y i 1 n InfFigs. 4, 5 'and 6, the invention is applied' tp1 a unchj26. In this form of the invention, t e guide bushing 28, tliroughwhich the punch 26 passes, is'removablyheld in a socket 29 in the arch, by a screw 30. Guide-posts'9 i z Intim-operation ofrthis formrof the'inl ase 8a is'formed with an arch 27 A so Y aresecured in thering 8a., A crosshea'd 10,1 l 'Vy has; aixed thereto sleeves 12awhich are slidably guided by vposts 9a. VSprings-14a are provided to lift' or retract the head and arts connectedthereto.l `The punch 26 isheldj in a chuck 29. Avstem 18a' is fixed tothe chuck and extends upwardly therefrom. f Stem 18aN is ysuitably secured in thecross-head 10n and is providedwith an anvil vbushing 20?. A hammer, conslstlngfof a' 'sleeve 211.,v a knob 22d, and a 'retracting spring 2311is applied to the stem'lSL77 in thesameymanner as here-j tofore .described in connectionwith the forml of the invention illustrated'in 'Fig'. 1. In order to limit `the downward movement of the punch 26, collars 3l. are slidably mounted3upon the guide rods 9a and are adapted KVto be rigidlyV secured thereto in any desired positionvby setrscrews 32. 'Y y vIn the operation of this form of the .in-y
vventi0n,' the base 8a is placed upon thema#` terial to be punched andy positioned accordingly.fThe operator will then adjust the Vcollars 31 to make the stroke of thevpunchy lthe desired/length, and imparta blow to the. head 22a, the impact of the hammer against the anvil 2()a causing the unch to be driven through thematerial.
