Specification of LettersiPatent.
, Patented Aug. 17, 1909.
Application filed June 8,1908. Serial No. 437,238.
To all whom it may concern:
Be it known that I, WILLiAM B. KILGORE, a citizen of the United States, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Punching- Machines, of Which the following is, a specification.
My invention relates to punching machines and particularly to punching machines adapted to perforate plates, angles and simi-v lar metallic forms used in structural and allied arts.
The object of my invention is to provide an accurate, facile and rapid means for accomplishing the perforation of blanks.
I accomplish these objects by-a novel arrangement and combination of parts, hereinafterdescribed, reference being made to the drawings forming part of this specification wherein z Figure 1 represents a vertical end view of myimproved punching machine. Fig. 2 is a plan view showing the correlation of the blank table to the templet table, with a punch, the greater part of the punch being removed for the sake of clearness. Fig. 3 perspective of the operating punch. Fig. 4 is an end view of said .arm and the electrical contacts, somewhatenlarged, and more clearly bringingout the detail thereof. Fig. 5 and punch therein, showing the gag by which said punch is locked inthe stock.
Referring again to the drawing for a detailed description of my invention, 1 represents'a punch of any usual type provided with a gear" 2, a pinion ciprocating the stock 6, 't'ormly, the punch 7 being loosely seated in the stock and free to recede thereinto, when brought into contact with at such times as said punch 7 may be, locked in the stock 6 by a suitable gag 8.
A bed adapted to support and carry the the blank except is a detail of the stock 3, connecting witln suitable belt pulleys 4- and fly wheel 5, by
' the punclt tt' holes.
blank to be operated upon is formed by a frame 9 provided with Wheels 10 adapted to move upon the rails 11-11 to allow for longitudinal movement of the said bed with the blank 12 carried thereupon. The rails 1111 are connected by suitable cross-bars 13-43 to forma carriage provided with grooved rollers 14-14, mounted in suitable bearings 15 and adapted to engage the rails 1616 to permit of transverse movement of said carriage. By this arrangement of the blank carrying bed, longitudinally movable and superimposed upon the transversely movable carria e, it will be seen that 1 obtain a universa movement of the blank so that any desired portion of the'surface of said blank maybe brought under the punch 7. Adjacent. these cooperating carriages is located a templet table 17 fixed rigidly in position and adapted to support the templet provided with templet holes 19 corresponding in relative position with the'perforations to be puncl'ied in the blank 12. The said templet. is, in practice, clamped rigidly to the templet table 17 and remains fixed relatively to the punch and does not have any movement whatsoever.
The blank-carrying bed is provided with a projecting arm 20 and suitable bracing 21, therefor, to rigidly connect the operating handle 22 with the said bed. By means of this handle 22 and connecting arm 20, the blank-carrying bed may be moved longitudinally 'and' transversely to bring the blank 12 into position to receive the punch 7. It will be understood that the blank 12 is rigidly clamped to the bed by meansof' suitable clamps 23 and suitable supporting means 24 upon said bed. Suitable bracing rods and bearings- 25, 25, 25 and 25" strengthen the bed and carriage. (.onnecting with the arm 20 is an index pin 26, preferably tapered and supported somewhat to one. side of the arm 20 by an extension 27 soas to be more apparent to the operator. This index pin is adapted to enter the templet holes 19 in the templet 18 when the arm '20 is guided by the operator, and when said index pin is brought opposite "to and inserted in the selected-templet hole, the said blank 12 is positioned so that x will make the perforation in the blank correspond with the said templet 18, of wood or other suitable material, and
being applied to said The index pin having been inserted in the templet hole, the operator clasps the handle 28 on the lever 29, fulcrumed at 30 and brings down the spring contact clip 31.
attached to the opposite end of said lever 29,
into engagement with the electrical terminals 32 and closes the circuit connecting found the. arrangement shown tobe con-' venient as it places the solenoid out of possible interference with the blank.
The index pin having been seated in the selected templet hole and the circuit closed by means of the handle 28, as above described, the gag 8 operated upon by the solenoid 34 is thrown in and locks the punch 7, whereupon the next descent of the punch 7 perforates the plate, or blank at the point corresponding in relative position to the templet hole of the templet. 'It will therefore be seen that the operator may, at will,
. successively punch the plate or other blank with any tions no matter how complex they may be, by the simple operation of desired arrangement of perforamoving the handle 22 until the index pin seats in the selected templet hole and, without changing the operators grasp upon said handle 22,
he may close the circuit and lock the punch as above described.
The springv 29 tends to hold the contact clip 31 out of connection with the circuit terminals when the handle 28 by the operator. that the operators entire attention may be, given to the entering of the index pin in the templet hole and that no attention whatsoever need be givento the blank or the punch, the templet once having been set for the operation and the, plate clamped upon its bed.
' Myjmproved apparatus is free from comphcatrons of gearmg and the like so that, there 15 no possibility ofany inaccuracy in the osition of the perforations punched in the lank and there can be no variation between the relative position of the templet holes and the perforations in the blank because of the direct and rigid connection of is not grasped the index pin with the blank-carrying table.
The advantages of .my improved appalratus will be apparent to those skilled in the I art, and
support adapted to rigidly support a 7 It will therefore be seen close and open said support adapted to support adapted to rece1ve a templet, a work a fixed templetsupport movable both longitudinally, and laterally, a tool cooperating therewith, an in dex-pin cooperating with said templet, means for moving said work support and index-pin in unison and a device for cont-rolling the operation of the tool, carried by and 'movable with said means said device being operable independently of the said means.
