COMBINED POWER AND HAND PUNCH.

The hole in the shaft is continued and claimed. A from this point preferably with a less diam- 5o In the drawings, Figure 1 is a perspective eter, thereby forming a shoulder, against loo ing through rod G.

which the inner end of the spring rests, and extends for fully Vone-half the length of the shaft.

G is a rod connected with clutch-section F and extending within hole G, and is connected to a movable collarH upon shaft E bymeans of a pin passing through the collar and an elongated slot in the shaft, the pin also pass- Collar H is moved longitudinally upon shaft E by means of a treadle K and its connection through rod l with a bell-crank lever I, having one arm resting within a peripheral groove H in said collar, by which means the clutch-sections are thrown into engagement to revolve shaft E.

E is an eccentric upon shaft E near the end thereof, the shaft having a reduced end portion journaled in the main frame, With an extension to which is attached a hand-wheel E", by which shaft E can be revolved by hand, for a purpose hereinafter stated.

L designates a plunger reciprocating in ways formed in the drill-frame and receiving motion through the medium of link L, 'the upper end of which is journaled upon eccentric E', and the lower end being connected to the plunger by a ball L", Working in a socket formed in the plunger, by which means the plunger may have an easy movement, Without possibility of being cramped in the ways. The lower end of the plunger is provided with means for attaching any preferred form of chuck for holding the punch.

To provide forautomatically supplying oil to the punch to prevent heating of the same, there is a chamber V formedv in the plunger, having a passage U, which communicates with an opening U in the side of the trame, by which oil is admitted to chamber V; and by means of a passage leading from chamber V to the opening NV in the plunger, in which the chuck is held, oil maybe fed through grooves W in the chuck-holder to the punch; or, if desired, the chuck may have a central perfo#A ration by which to lead oil to the punch.

O designates the die-bar, which is of oblong .rectangular form, and which is provided on oneor more of its sideswith die-plates P. These die-plates P are of different sizes and shapes to accord with different classes of Work to be produced by the machine, so that the saine bar is adapted for a great variety of Work, and, as will presently appear, may be readily adjusted for the different classes of work to be performed.

An opening or socket extends longitudinally through the base of the frame, and into "the top and sides of said base are tapped setscrews O', as is best shown in Figs. 3 and 4. The die-bar O is inserted lengthwise into the opening or socket in the base, and is held in its required position by the set-screws O. The bar O is inserted to a greater or less extent within the socket, according to the particular die-plate to be brought into operative position beneath the punch, and after one die-plate has been used the die-bar may be turned sideWise or Vreversed longitudinally to bring any one of the other die-plates into operative position, as desired, the set-screws O being simply first loosened and then tightened up again after the bar has been properly adjusted. Thus it will be seen that the same die-bar may be used for a great variety of work, and that the inconvenience arising from the use ot` a great number ot die-bars is avoided.

M is a vertical hanger suspended from the frame, and having a stripper N pivotally secured thereto by a bolt N', passing through the stripper and hanger, by which means the lower portion of the stripper can move laterally with relation to the hanger, the bolt N being the pivot upon which the stripper turns. This movement allows the stripper t swing to one side or the other ofthe hanger. Should there be an irregularity in the metal being punched, a stud M upon the hanger enters a slot upon the back of the stripper and tends to steady the same in its lateral movement.

So far the device has been described as a power-punch, in which power is transmitted by belt to pulley B, and through pinion C to gear D, the clutch-sections being disengaged by means of spring G,preferably coiled around rod G', counter-shaft E remaining stationary. The metal to be punched is placed upon dieplate C, and, if desired, the punch may be brought to bear upon the metal previous to punching, in order to ascertain if the metal is in proper position, by means of hand-Wheel E, which upon being revolved turns shaft E and eccentric E', bringing the punch down to the metal. If desired, the punch may be raised by turning the shaft to bring the eccentric to its highest point, or power may be applied with the punch resting upon the metal. To apply the power, treadle K is depressed, throwing the clutch-sections D and F into engagement.,and the punch is depressed, as described,

To insure an unvarying feed of lubricant to the punch to avoid heating ot the same, oil is poured through perforations U and nds its way to the chuck through passages U and W.

Q designates a bevel-gear rigidly keyed to shaft E, and with segmental gear S, fulcrumed upon stud R, constitutes a hand-power attachment to the punch, gear S being operated by IOO IIO

a handle S, attached to a socket-piece T,

formed integral with said gear.

To operate the punch by hand-power, the handle S is secured to the socket portion T of segmental gear S. Said gear is fulcrumed upon stud R, with the segmental gear in engagement with bevel-gearQupon shaft E. To

raise or depress the punch, handle S is re- ,l

ciprocated, causing segmental gear S to give a suficient rotative movement to shaft E to cause eccentric E to move to its highest or lowest point, thereby reciprocating the plunger and punch connected therewith. y

The device is compact, consists of few parts, and is easily manipulated by the operator.

IVhat I claim, and desire to secure by Letters Patent, is-

l. In a punching-machine, a power-shaft, a pinion keyed thereon, a counter-shaft, and a gear loosely journaled thereon and held from longitudinal movement by a rightangled keeper attached to the punch-frame, and having an angled portion projecting into a groove in the hub of the gear, as and for the purpose setforth.

2. In a punching-machine, a counter-shaft and a gear loosely mounted thereon receiving motion from a power-shaft, in combination with a clutch-section having a longitudinal movement upon the counter-shaft and operated bymeans of a spring and rod within the counter-shaft, as and for the purpose set forth.

3. In combination with a shaft having a cylindrical bore, a clutch section having a longitudinal movement upon the shaft, a gear loosely j ournaled upon the shaft and provided with a clutch-face, with a rod located Within the bore connected to ashipper-collar and clutch-section, and a spring bearing against a portion of the shaft and the clutch-section, as and for the purpose set forth.

4. In a punching machine, the combination, With a frame and Ways formed in the same, of a plunger reciprocating in said Ways and carrying` a chuck, an opening' or perforation in the Ways, an oil-chamber located near the lower c nd of the plunger, a passage leading from the side of the plunger to the oilchamber, and adapted to, While in operation, intermittently communicate with the opening in the Ways, and a passage leading from the chamber to the chuck held Within the plunger, substantially as described.

5. In a punching-machine, a frame and a hanger secured therein, in combination with a stripper pivoted upon the hanger to allow of lateral movement With relation. to the hanger, as and for the purpose set forth.

G. In a combined power and hand punch, a counter shaft, a bevel-gearl keyed thereon, a segmental gear journaled upon the frame and engaging with the bevel-gear, and a lever for operating said segmental gear, as and for the purpose set forth.

7. In a punching machine, the combination, with a frame provided with an opening through the base thereof, of a die-bar having interchangeable faces and carrying a plurality of non-aligning die-plates, and set-screws for holding the bar Within the frame, whereby said die-bar is adapted to be moved `longitudinally,reversed, or turned, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I hereby aiix my signature in presence of two Witnesses.

DANIEL WARNER.
