PUNOHING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 749,164, dated January 12, 1904. Applic 'September 1,1903. swarm. 171,542. (No model.)
To all whom it may concern:
Be it known that I, ERWIN A. BURKE, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Punching-Machines, of which the following is a specification.
This invention relates particularly to a punching machine designed to punch sizemarks in leather uppers or pieces used in making shoes, although it is not limited thereto,
but may be used for punching sheets of any kind.
With respect to its utility in shoemaking it may be said that the prevailing method of shoe factories is to mark the size-marks on the pieces with ink or pencil, so that when the pieces are assembled shoes of proper sizes will be formed. This method is unsatisfactory and unreliable, because the marks are apt to be obliterated in the handling to whichthe pieces are subjected.
By the machine hereinafter described permanent marks are made by punching holes in the edge of the pieces, which will be taken up or covered by the seam or lap when the parts are assembled.
Mechanism is provided for selecting various punches to give all the size-marks desired by various combinations of punches of different sizes or shapes. Shoe-sizes run, say, from one to thirteen and one-half, and by various combinations of seven punches, comprising two large punches, four small punches, and a dash or elongated punch, all the sizes and half-sizes can be distinctly shown. The combinations of punches is entirely arbitrary, and therefore need notbe described.
The punches are selected by means of a dial containing Various openings, according to the sizes to be marked, and this dial is rotatable under the feet of the punches, so that it supports the selected punches when the die descends, but allows. the remainder of the punches to dfiop into said openings and not perforate the s eet.
The machine is also characterizedby other.
novel and improved features, as will be more apparent from the following description.
5 1n the accompanying drawings, Figure 1 is a side elevation of the machine. front elevation thereof. Fig. 3 is a top plan view. Fig. 4 is a plan of the dial or punchselector. Fig. 5 is afragmentary vertical section on the line 5 5 of Fig. 2,'and Fig. 6 is a fragmentary vertical section at right angles thereto.
Referring specifically to the drawings, the bed-plate of the machine is indicated at 2, and 10 indicates a stripper-table thereon supported by springs 12 and bolts 11, around which the springs are coiled. The bolts have vertical motion with the table, their heads being let into guide-recesses in the under side of the bed. The upward movement of the table is stopped when the heads strike the top of the recesses.
The punches are indicated at A and are held in the holder 25, set in a recess in the top of the bed and held therein by a screw D. The feet of the punches are enlarged, as shown at Fig. 2 is a.
26, so that they cannot rise through the holder. They work through openings formed in the bed-plate, according to the position of the selector-dial 21, as hereinafter described. This dial is keyed to a bolt or short shaft 20, which turns in bearings in the frame of the machine, and has openings (indicated at 21) which are arranged radially according to the punches to be selected and circumferentially to be positioned directly under the feet of the punches. It is evident that when the punches receive pressure from above such as register with the hole or holes in the selector-plate will drop therein out of action, while-those which do not register with the holes will be supported on the dial and punched through the sheet.
The dial is moved to the desired position by a hand-wheel 5, working under anindex 5, attached to the frame of the machine. This hand-wheel is'keyed on 'the bolt 20 and has marks thereon corresponding to the proper openings in the dial-plate according to'a predetermined arhitrary system. The edge of the dial is notched to engage with a spring 22,
which holds it in the position at which it is set.
To the underside of the stripper-plate. 10 is attached a casing 14, carrying two frictionblocks 16, which bear against opposite sides of the punches, and the pressure of these friction-blocks is regulated by screws 15. The purpose of this is to lift the-depressed or nonselected punches to the extent permitted by the feet 26, and thereby return the punches to their original raised position after each action. The stripper-plate also carries a guide or gage 17.
The die is indicated at 27, carried at the lower end of a plunger 4., which slides up and down in guideways formed in the overhanging hollow arm or frame 1. The plunger is retained in the guides by a removable faceplate 6 and is actuated by a lever 3, which is pivoted at 8 and works in the hollow of the arm. This lever is conveniently extended below to be operated by a treadle. The die contains holes corresponding to the punches in position and size, and the plunger is undercut, as at 4, above the die to let out the punchings.
In operation the sheet or pile of sheets is placed on the stripper-plate against the guide above the punches and the index-plate set to the desired position according to the size or other marks to be punched in the sheets. The plunger and die are then lowered. The selected punches are supported by the dial-plate, and consequently perforate the sheet. Such of the punches as register with the openings in the dial-plate drop therein and do not operate. When the die is lifted, the stripper 1O rises, carrying with it the punches, by means of the friction of the plates 16, to the original position. The punches are carried by and move with the stripper-plate both up and down, except as they are stopped, when the stripper is depressed, by striking the imperforate portions of the disk.
hat I claim as new, and desire to secure by Letters Patent, is
1. In a punching-machine, the combination with a movable die and a cooperating gang of punches, and a punch-holder in which the punches are movable, of a selector-plate under the feet of the punches, supporting the selected punches and having openings into which the rest of the punches recede, and means to lift the punches when the die is retracted.
2. The combination with a die and a gang of punches, movable to and from each other, of a punch-holder in which the punches are movable, and a rotatable selecting-support for the punches, having various openings which may be registered with non-selected punches to permit the same to recede.
3. The combination with a die and a gang of punches, movable to and from each other, of a holder and a selecting-support for the punches permitting non-selected punches to recede, a stripper working between the die and punch-holder, and means carried by the stripper to advance the non-selected punches when the die and punches part.
. 4C. The combination with a die and a gang of punches movable to and from each other, of a holder and a selecting-support for the punches permitting non-selected punches to recede, a stripper working between the (lie and punch-holder, and friction-blocks carried by the stripper and engaging the non-selected punches to advance the same when the die and punches part.
5. In a punching-machine, the combination with a die and a gang of punches relatively movable, of a punch holder in which the punches are severally movable, and a rotatable selecting-disk supporting the selected punches and having various radially-arranged recesses which may be registered with non-selected punches to permitthe same to recede.
6. In a punching-machine, in combination, a bed, a gang of punches working therethrough, a selecting-support for the punches under the bed, a spring-supported stripper on the bed and having openings through which the punches work, a friction device carried by the stripper and engaging the punches to lift the same, a stop limiting the lift of the punches, and a reciprocating die cooperating with the punches.
7. In a punching-machine, the combination with a movable spring-supported stripper, of punches normally carried thereby and movable therewith, a die cooperating with the punches and acting against the stripper to depress the same, and a selective support for the punches, under the stripper, stopping the motion of selected punches when the stripper is depressed.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ERVVIN A. BURKE.
