AUTOMATIC PU NCHlNG-MACHINE.
Specification of Letters Patent.
Patented Nov. 21, 1905.
Application filed March 26, 1904. Serial No. 200,126-
T 0 all whom, it may concern.-
Be it known that we, Oi-rARLns J. GADD, a subject of the Kingof Great Britain, and DA- v11) J. JENKINS, a citizen of the United States, both residents of Steelton, Dauphin county, Pennsylvania, have invented certain new and useful Improvements in Automatic Punching- Machines, of which the following is a specification.
Our invention relates to improvements in automatic punching-machines; and the object of our invention is to furnish a machine for automatically and accurately punching a series of holes in a piece of metal in a straight line at such distances apart as may be desired.
Our invention consists of a reciprocating punch, a gag by means of which said punch may be put into or out of operation, means for feeding the metal to be punched to said punch, and electrically-operated means for putting said gag and said punch into or out of operation.
In the accompanying drawings,forming part of this specification,and in which similar characters of reference indicate similar parts throughout the several views, Figure 1 is a side elevation, partly in section, of our improved punching: machine shown diagrammatically; Fig. 2, an end elevation of the means for carrying and driving the pattern from which the movements of the punch are dictated; Fig. 3, a plan of pattern for dictating movements of punch; Figs. i and 5, longitudinal central sectional elevations through two forms of punch-movement-dictating patterns.
a is a punch-carrying head which receives a reciprocating motion through any suitable form of mechanism.
In the drawings, 6 is a hydraulic cylinder carrying the usual piston to which the head a is attached or of which it forms part; but any other suitable form of apparatus for carrying and actuating this head may be employed.
cis the punch which is carried by the head a.
d is a gag carried by a head a. This gag is furnished with a perforation e, which when the gag is in one position permits the passage of the punch and in another position engages and holds the head of the punch.
f is a solenoid-magnet the core of which is attached to or forms part of the gag cl.
g is a part of the gag which carries a head it.
t' is a spring bearing against head it and the punch-carrying head a, which operates to return the gag (Z to its normal position after having been operated upon by the solenoid f.
j is the die under punch 0; Z), a piece of metal to be punched; Z, rollers for carrying the metal k.
m is a table carried by, carrying, or forming part of a rack 77/, 0, a pinion for driving rack 71; p, the shaft which carries pinion 0.
r is a rachet-wheel fast to shaft s is a pawl engaging ratchet 1,- zf, a bellcrank, to one end of which pawl s is attached; it, a rod connecting the other end of bellcrank it and one end of a bell-crank o, the other end of which is attached to or operated by the movements of the punch-carrying head a.
l is a tape or pattern through which the movements of the solenoid f and of the gag (Z and of the punch c are directed. This tape may be of an insulating material carrying metal or other contact-points 2, as shown in Fig. i, or it may be furnished with perforations 3, Fig. 5, through which the insulated contact-point 4, Fig. 2, carried by frame 5, may pass. The pointd is connected electrically with one pole of the solenoid by a wire 6, for instance, and the frame 5 is electrically connected through a wire 7, for instance, with the other pole of thesolenoid, the frame 5 and the tape 1 or the points 2 carried by this tape being connected electrically to any suitable source of electrical supply. The rack n is connected in any suitable manner through a chain 8 and clamp 9, for instance, with the plate The contact-points 2 or 3, carried by the tape 1, are spaced as are to be the holes desired in the plate 7d, each contact-point representing one hole in the plate. The contactpoints may be placed as far apart as are the holes, or they may be farther apartor closer together; but the tape must be so moved in relation to the plate that at each contact of one of these points with point 4: a hole will be punched in the plate by the punch 0, the holes being punched according to the relative movements of thetape or plate.
The operation of the device is as follows: The head a is constantly reciprocated. Upon its movement in one direction the bell-crank 'u is operated to draw the connection a over to cause the bell-crank t to raise the pawl s,
which turns the ratchet a, which is fast to,
shaft 29, which carries pinion 0, which gears with and drives the rack 12/. By the mechanism described the rack 72, is intermittently advanced, and with it the sheet of metal 7': to be punched. So long as the contact-point 4: is out of engagement with one of the contactpoints carried by the tape 1 the solenoid f is inert and the gag (Z is in the position shown in Fig. 1tha't is, the hole a in the gag is directly over the punch, and when the punch engages the plate it is pushed up into this hole, making no impression on the plate. As soon, however, as the contact-point 4 engages one of the contacts on the tape current is thrown into the solenoid, the core of which is thereby drawn out, and the gag is moved so as to block the upward movement of the punch. A downward movement of the punch new results in a hole being punched in the plate. As soon as the contacts t and those on the tape are disconnected the solenoid becomes inert and the spring 7; returns the gag to its first or normal position. Of course this action might be reversed, the solenoid acting to draw the gag into position to pass the punch and the spring to draw the holeo in the gag to one side of the head of the punch. This arrangement would necessitate a corresponding change in the tape lthat is, the points 2 would be insulated, while the rest 0} the tape would be in electrical contact with the point 4. It will be observed that after the plate 7': is set so that the punch 0 will punch the first hole accurately the following holes will be punched exactly as may be dictated by thecontact or insulated points 2 on the tape 1, the tape taking the place of the usual templet, so far as the spacing of the holes is concerned, and in addition serving to direct the movements of the punch and of the plate.
It has been thought sufficient to illustrate in this application but a single punch. in
practice any number of punches may be used, the movements of one, two, or more of which may be controlled through a single tape or the movements of each separate punch may be controlled by a separate tape.
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a punching-machine, in combination, a reciprocating head, a punch loosely carried by said head, a gag carried by said head by means of which said punch may be operatively connected or disconnected with said head, electrically-operated means for operating said gag, a table, means operated by the movements of said head for intermittently driving said table, a connection between said table and the metal to be punched, a tape or templet having alternately -spaced electricallyenergized and inert points carried by said table, and an electric contact-point, connected with the electrically-operated gag mechanism, adapted to be alternately energized and deenergized by contact with the points upon said tape or templet.
2. In a punching-machine, in combination, a reciprocating head, a punch loosely carried by said head, a gag carried by said head by means of which said punch may be operatively connected or disconnected with said head, a solenoid for operating said gag in one direction, a spring for operating said gag in the other direction, a rack, a pinion for driving said rack, means operated by the movements of said head for intermittently driving said pinion and rack, a connection between said rack and the metal to be punched, a tape or templet having alternately-spaced electrically-energized and inert points carried by said rack, and an electrical contact-point, connected with said solenoid, adapted to be alternately energized and deenergized by contact with the points upon said tape or temp et.
