Serial No. 561,732.
To all whom it may concern:
Be it known that I, ERNEST G. CLARK, a citizen of the United States, residing at De Kalb, in the county of Dekalb and State of Illinois, have invented new and useful Improvements in Machines for Itectifying Perforated. Music and Masters, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
The purpose of this invention is to provide an apparatus serviceable for rectifying the perforations of perforated controller sheets, commonly called perforated sheet music or perforated rolls, which are made for the purpose of controlling the operation 0% automatic musical instruments and the lire.
It consists in the elements and features of construction and their combination shown and described as indicated in the claims.
In the drawings: Figure l is a plan view of a machine embodying this invention a part of the machine being broken away to diminish the compass of the figure. Fig. 2 is a section at the line 22 on Fig. 1. Fig. 3 is a section at the line 33 on Fig. 2. Fig. 4 is a detail end elevation of a paper feeding mechanism. Fig. 5 is a detail, sec tion at the line 55 on Fig. 4. Fig. 6 is a detail front elevation of the punch and die carrying jaws and the pressure foot. Fig. 7 is a section at the line 77 on Fig. 6. Fig. 8 is a detail section at the line 88 on Fig. 2. Fig. 9 is a front elevation of the pressure foot. Fig. 10 is a top plan of the same. Fig. 11 is an end View of the punch.
The machine shown in the drawings, comprises a base, 1, upon which there is mounted at one end a low standard, 2, and at the other end, a standard, 3, and intermediate them near the low standard, a third standard, 4. The standard, 2, has two short upstanding bosses, 2, 2*, into which rods, 5, 5, are screwed, extending thence to the standard, 3 which has similar low bosses, 3, 3 which receive the opposite ends of said rods, the two standards, 2, and 3, being thus rigidly connected by the two rods. The standard, 3, has besides the bosses, 3, two posts, 3 3 and the standard, 4, has similar posts, 4, 4", and rods, 6, 6, parallel to the rods, 5, 5, connect the posts, 3 respectively, to the posts, 4", said rods extending between the upper ends of said posts respectively, and being therefore considerably higher than the rods, 5, 5. The frame composed of the base, 1, the standards, 2, 3, and 4, and the rods, 5 and 6, has mounted upon it for sliding upon said rods, 5, and 6, a device of the nature of a die press, being a bifurcated carriage, whose lower arm or member is mounted for sliding on the two lower rods, 5, 5, while its upper arm or head is similarly guided upon the upper rods, 6, 6. This die press, 7 has its said lower arm, 7*, provided with four downwardly projecting lugs, two at each end, which are penetrated by and slide upon the two lower rods, 5, 5. The upper arm, 7 has at the end a cross head arm, 7, penetrated at its two ends by the upper rods, 6, 6, upon which said cross head thus runs as the entire device called the punching press travels from rightto left on the rods, 5 and 6. In the left hand end portion of the overhanging arm, 7, which said end portion may be called the head of the punching press, there are mounted for vertical reciprocation two punches. 9, 9, which are each upheld by a spring, 10, whose action for so up-holding them is checked by a stop, 11, mounted upon an up-standing stud, 12, screwed into the upper side of said head, the stop being adjustable on the stud for Varying the point at which the punch is stopped in its upward movement. Between the upper ends of two upright plates, 13, 13, which are mounted upon the front and rear sides respectively, of the head, 7, there is mounted for rocking in a right and left vertical plane, a cam, 14, whose lower edge bears upon the upper ends of the punch, 9, the eccentrically projecting end portion of the cam extending right and left beyond the point of bearing of the cam on the heads of said punches, so that as the cam is rocked in one direction it depresses one of the punches, and when rocked in the opposite direction it depresses the other punch. For rocking the cam there is mounted upon the same rock shaft, 15, upon which said cam is mounted, an operating lever arm, 16, which when swung over to the right encounters a pin, 14, in the right hand end of the cam, for depressing that end to depress the right hand of the two punches, 9; and when swung in the opposite direction encounters a similar pin, 14, set in the left hand end of the cam, causing the cam to be depressed at that end for forcing downward the left hand portion, 9.
The studs, 12, upon which the stops, 11,
are mounted, serve themselves as stops for the swinging movement of the lever arm, 16, which strikes the upper end of one of said studs when swinging to the left and of the other when swinging to the right, such oncounter occurring after the cam has been rocked far enough. to properly depress the punch upon which it operates by such rock ing. In the lower arm, 7" of the punching press, there are mounted dies, 17, 17, in proper position to cooperate with the punches, 9, 9, when the latter are depressed. Upon the forward side of the head, 7, and specifically upon the forward side of the forward upstanding plate, 13,. there is mounted a presser foot, 20, having a vertical member which is guided upon and retained in contact with the plate, 13, by broad-headed screws, 21, 21,which extend through slots 20, 20 in the said vertical arm of the presser 20. A third slot, 20 is provided, to accommodate a pivot screw at 22, upon which there is pivoted the presseroperating cam or presser foot lifter, 2 1, whose edge, eccentric to its pivot, engages a stud, 26, projecting forwardly from the vertical arm of the presser, 20. As said presser lifter is swung upward. for lifting the presser by the travel of the eccentric edge of the latter under said stud 26, the latter passes off the eccentric portion of the edge onto the abrupt shoulder, 24, which causes the presser to be locked in elevated position. The presser has an elongated foot-piece, 25, which extends fore-and-aft across the dies, 17, between the same and the head, 7*. This presser foot has parallel, longitudinal slots, 25, in the fore-and-aft Vertical lanes of the punches, 9, and said slots have enlargements, 25 at the points in their lengths which are situated in the vertical path of descent-of said punches respectively, through which enlargements the apertures in the dies and a small area around said apertures are exposed to view from above; and the presser foot may have upon its upper side a transverse line, 24, at the vertical plane of either the front or rear edge of the punch. Such line when present, merely serves as a gageline to assist the operator in positioning the paper so that the edge of the cutting made by the punch will be at the precise point desired.
From the foregoing description it may be understood that a perforated music sheet or controller for automatic musical instruments being passed between the two arms of the punching press and moved longitudinally to bring the apertures which are to be corrected in the transverse line or path of adjustment of the punches and the punch ing pres being then moved upon its guide rods at the right or left to bring one or the other of the punches into vertical alinement with the point requiring correction, the operator by means of the lever handle, 16, inayvdepress the punch and make the correction in the perforation; and that for holding the papers accurately in position while making the perforation, the presser, 20, may be lowered thus holding the paper firmly upon the opposite die when the punch descends.
For feeding the paper through between the two arms of the die press, there are provided a feed roller, 30, and a pressure roll, 31, mounted beyond the die press, and extending parallel to the rods, 5 and 6, upon which the die press is mounted for sliding. For supporting these rolls, standards, 32 and 33 are mounted upon the base, 1, and in these standards, the lower or feeding roll, 30, is mounted directly. Arms, 34, extend off from each of the standards, 32 and 33, and to these arms which are rigid with the standard, respectively, there are pivoted swinging arms, 35, 35, in the free ends of which the pressure roll, 31, is journaled. Springs 36, 36, connect the free ends of the arms, 35, with the fixed standards, 32 and 33, respectively, for holding the swinging arms, 35, down, to keep the pressure roll, 31, pressed upon the upper side of the feed roll, 30 with a yielding pressure to cause the paper to be gripped between the two rolls for feeding when the rolls are revolved as hereinafter described.
In order to separate the rolls when it is desired to release the paper, cams, 37, are
,mounted upon the opposite ends of the shafts of the pressure roll, said cams having operating arms, 38, which are longer than the radius of the pressure roll, and which extend out past it, and are connected by a rod, 39, above and in front of the pressure roll, by which the operator can operate both the cams at once, pressing down upon the rod for rocking the cams to separate the two rolls, studs, 40, being set in the upper side of the bearings of the feed roll, and projecting upward in the plane of the cams respectively, whose eccentric edges bear upon the upper ends of these studs for pro- 1 lufiing the cam action to lift the pressure ro For operating the feed rolls to feed the paper as fast as desired and bring it to rest in any point of desired correction in alinement with the punch, there is mounted upon the left hand end of the shaft, 30 of the feed roll, 30, a ratchet disk, 45, and there is also mounted for rocking upon the shaft adjacent to said disk a pawl lever, 46, carrying a pawl, 47, for engaging the ratchet. A friction stud, 48, mounted in the bearing standard, 32, of the feed roll, is pressed upward by a spring, 49, against the end portion of said feed roll operating as a brake and check, both to prevent the roll from being over-fed by too rapid action of the operatin pawl lever and also to operate as a detent or preventing the roll from being reversed in the retraction of the pawl over the ratchet.
In order that the die press may not be in danger of slipping or moving longitudinally on its guide-ways, after it has been positioned for making a correction while the punch is being depressed, there is preferably 10 provided a thumb-screw, 50, set into one arm of the cross head, 7 for impingement against the upper guide rod, 6, to secure the rest at adjusted position, but releasably so that it may be quickly and easily freed for adjustment to a new position.
By providing the punching press head with two punches and providing corresponding dies in the lower arm, the punches being spaced apart along the path of movement of the punching press, it is rendered possible to reduce the total range of such movement of the press by the amount of the distance between the two punches or nearly that distance'because the one standing farthest toward the right hand can be used to reach the right hand portion of the paper and the punch standing farthest toward the left hand can be used to reach the left hand portion of the paper. Obviously, for the maximum advantage of this sort, the two punches would be spaced apart nearly half the total width of the perforated area-to be reached for correction.
