PAPER-PERFORATING MACHINE SPECIFICATION forming part of Letters Patent No. 599,560, dated February 22, 1898.
Application filed September 17, 1897- Serial No. 652,024. (No model.)
To all whom it may concor-7b.-
Be it known that I, FREDERICK W. HEDGE- LAND, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Paper-Perforatin g Machines, of which the following is a specification.
This invention relates more especially to perforating-machines for perforating the music-sheets used in self-playing instruments. It may, however, be used for perforating paper for other uses.
The main feature of the invention lies in the mechanism employed for operating the punches. The stems of the punches are made extensible, preferably by insertingr in them or adding to them a toggle the normal position of which is one of contraction, and the toggles are expanded or straightened by the action of an electromagnet whenever the punches are to be operated. The straightening of the toggles lengthens the stems, so as to throw the upper end thereof into the path of a rapidlyrotating cam extending across the series of punches and acting to force the lengthened ones downward and cause them to operate before their toggles can relax. After the operation the punches are raised from the paper by a lifting device, also common to all punches, and operated at each revolution of the camshaft, and the toggles are contracted by suitable springs. By this construction I obtain such rapid action by the punches as enables me to feed the paper continuously and to obtain the very best results both in the quality of the work and the ease and rapidity with which it is done.
The nature of the invention is fully disclosed below and will be understood from the accompanying drawings, in which- Figure l is a front elevation of the machine, and Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a detail showing the connection between one. of the toggles and its magnet.
In said drawings, A Arepresent the end uprights of the machine, by which most of the DD are the punches. in a straight line transverse of the machine and in such number as the work requires. They work vertically in guides D D2 D3 D4. The toggles are shown at Dsand are located between the ends of the punches, the main portion thereof being below and theextremities D6 being above the toggles. The normal condition of these toggles is indicated at Fig. 2 by full lines and is one of contraction, while the extended position is shown by the broken lines in the same ligure. In the latter position the upper extremities D6 of the several punches are raised sufficiently to bring them into the path of a cam E upon the shaft E', journaled in the uprights A and rapidly driven by the pulley E2 andl so the punches will receive a downward thrust from said cani. This cam-shaft extends over the entire series of punches and operates any of them which may be extended. The downward thrust thus imparted to the punches causes them to perforate the paper. A stop D7 limits the upward movement of the upper part I)6 of the stems by encountering the shoulders D8 upon the stems. A balance-wheel E3 is preferably employed on the shaft E.
To bring about the straightening of the toggles and the lengthening of the punch-stems, each toggle is connected to al separate actuating devicev under the control of a sample music-sheet or of the musical instrument, the playing upon which is to be recorded in the sheet being perforated. I show a suitable form of the actuatingdevice, but the connections between it and the sample music-sheet or the instrument whose playing is recorded are not shown, as they form no part of the present invention, and are, moreover, well known to those skilled in the art. In my preferred construction the actuating device is an electromagnet F, the armature F of which is made in the form of a'rocking elbow-lever and the vertical member of which is connected to the toggle to which it belongs by a wire tie F2, as shown. The energizing of the magnet rocks the armature and thereby draws the toggle to its extended position, as shown by the broken lines in the case of one of the toggles in Fig. 2. In order to compact the Inachine as much as possible, I arrange the sc- They are arrangedA II OO ries of magnets in four rows-two rows in front and two behind the punchesand invert some of them, as illustrated, and I also bring the operating ends of the armatures all to the same level, so that they may draw directly and to good advantage upon the toggles.
To shorten the toggles after the magnets have ceased action thereon, springs G are attached one to cach armature and act thereon in a direction opposed to the magnets. The springs are of course of little strength, so the magnets may readily overcome them.
After each perforating operation the punches are lifted out of the paper by suitable means-such, for instance, as the rocking lifter Il, consisting of a wide bar extending across the series of punches and engaging the pins H', inserted therein. This bar or lifter is pivoted at its ends at H2 and is rocked constantly and rapidly by the eccentrics H3 upon each end of the cam-shaft and the connecting-arms H4. A weight H5 is preferably attached to the lifting-bar H, outside of the pivots H2, to balance the weight of the acting edge of the lifter, in order that the lifter may be easily operated and not jar the machine. The eccentrics are arranged so as to cause the lifter to rise immediately after the cam has depressed the punches, whose toggles are straightened, and consequently the punches are withdrawn from the paper instantly upon the completion of the perforation, so that they do not interfere with the continuous feeding of the paper and, indeed, allow the paper to be fed at a much greater speed than has he retofore been possible. A guide L, immediately over the table and close to the line along which the perforations are made, prevents any lifting of the paper with the punches as they m ove upward. The table I3 along said line is provided with openings B', having cutting edges and giving room for the punches to descend through the paper.
The operation of the machine is as follows: The shaft E and the take-up roll C being both set in motion by suitable driving mechvanism and the magnets being also electrically connected to the devices, so that the musicsheet being reproduced or the instrument being played may control them, the magnets corresponding to the keys or notes which are to be represented in the sheet being perforated as being sounded are energized and their armatures are operated, so that the togglcs of the punches corresponding to the energized magnets are straightened, thereby extending the stems of those punches and insurin g their being operated in perforatin g the paper as soon as the cam E encounters them. As the cam is rapidly moving it follows that the perforations are made almost instantly and before any relaxation of the toggles. The punches are also retracted instantly afterward by the lifter, which rises with every revolution of the cam-shaft. In the case of long notes the perforations are repeated and so close together as to form continuous openings, the magnets remaining energized so long as the notes sound and thus retaining the toggles in their expanded positions for the same length of time, and while this condition obtains the punches will be alternately depressed and lifted by the cam and lifter. The springs cause the relaxing of the toggles whenever the magnets are cutout of circuit, being assisted in that operation by the lifter.
I claiml. The combination in a papcr-perforating machine, of punches each embodyingbetween its ends a toggle D, means for straightening said toggles, means for lifting the punches and a rapidly-moving cam acting upon thc upper ends of the punches when the toggles are straightened, substantially as specified.
