"WILLARD S. PAIN, OF MERIDEN, CONNECTICUT, ASSlGN OR TO THE AEOLIAN 00., OF NEW YORK, N. Y., A CORPORATION OF CONNECTICUT.
MACHINE FOR CUTTING AND PRINTlNG STENCIL-=SHEETS.
SPECIFICATION forming part of Letters Patent No. 690,991, dated January 14, 1902. Application filed May 24, 1901. Serial No. 61,693. (No model.)
To all whom it may concern:
Be it known that I, WILLARD S. PAIN, of Meriden, in the county of New Haven, State of Connecticut, have invented a new and useful Improvement in Machines for Cutting and Printing Dots upon Stencil-Sheets for Use in Preparing Music-Sheets for Mechanical Musical Instruments, of which the following is a specification.
IO In mechanical musical instruments of the kind which are controlled by perforated music-sheets it is common in manufacturing the music-sheets to first prepare a perforated stencil-sheet, and it is customary to print a numher of dots over such stencil-sheets and also to out near the edges of such stencil-sheets a number of apertures regularly disposed and suitable for engaging with a toothed feedwheel.
The object of the present improvement is to provide an effective machine for cutting these apertures and also printing the dots.
A machine embodying the improvement will be fully described and then its novel features will be pointed out in the claims.
In the accompanying drawings, Figure l is an elevation of one side of a machine embodying the improvement, certain parts being omitted to economize space. Fig. 2 is an elevation of the other side of the machine, certain parts being omitted to economize space. Fig. 3 is aplan of the machine with the middlelongitudinal portion removed to economize space. Fig. 4 is a transverse vertical section at the plane of the dotted line at, Fig.
3. Fig. 5 is an elevation of certain parts omitted from Figs. 1 and 2 and delineated as they would appear if included in Fig. 2. Fig. 6 is a view of the parts shown inFig. 5, but as they appear in a plane transverse to the length of the machine. Fig. 7 is a detail side elevation of certain parts. Fig. 8 is a view of a portion of a printed stencil-sheet.
Similar letters of reference designate cor- 5 responding parts in all the figures.
It will be readily understood from a glance at Fig. 7 that the stencil-sheet A to be prepared in this machine is to have two rows of apertures a a regularly disposed in lines parallel with each other and parallel to and near the longitudinal edges of the sheet. It
will also be seen that intermediate of the two rows of apertures a a a number of rows of dots extending transversely to the length of the stencil-sheet and parallel with each other are printed upon one surface of the sheet. It has been found convenient to provide in each of the rows of apertures a a twelve apertures to each foot of the length of the sheet and sixty of the transverse rows of dots a to each foot in the length of the sheet.
The frame B of the machine may be of any desirable construction and made of anysuitable material. It is shown as comprising a table I), having guides b for coacting with the side edges of the sheet to be formed into a stencil.
Above the table I) is a punch-bar C, adapted to reciprocate vertically by sliding along posts or studs b extending upwardly from the table I). The ends of the punch-bar are connected bya screw 0 with rods 0 of eccentrics c, mounted upon a shaftD, constituting the main or driving shaft of the machine. Motion may be transmitted to the shaft D by means of a belt passing around a pulley d, affixed to said shaft.
The punch -bar C is provided with two punches c fitting in slideways and adjusted by set-screws c. A sheet to be formed'into a stencil is fed under these punches, and when they descend through it they will form the first of the rows of apertures a a \Vhen the punch-bar raises the punches, the sheet will be fed an inch forward and then allowed to stop while the punches descend again to form the next apertures. This operation is repeated at the same intervals until the sheet reaches the toothed feed-wheels E, afhxed to a shaft E, carrying a bed-roll E for sup- 9o porting the sheet. On this shaft is also affiXed a gear-wheel E Opposite the bed-roll E is a printing-roll F, having its surface properly formed for printing the rows of dots a in the stencil-sheet. On itsshaft F is affixed a gear-Wheel F which meshes with the gearwheel E The bed-roll and the printingq'oll are of the same size and rotate in opposite directions, but at uniform speed, because their gear-wheels E F are also of the same 10c size. The toothed feed-wheels E are a foot in circumference at the pitch-line and each one has twelve teeth. The bed-roll and the printing-roll are also each a foot in circumt'erence. By adopting these proportions the stencil-sheet will be provided with twelve apertures in each row a a and sixty rows of dots a for every foot of the length of the stencil-sheet. Motion is imparted to thebedroll E by a pawl e, pivotally connected to a pawl-lever e, loosely mounted upon one of the journals of said roll and coacting with a ratchet-wheel e which is affixed to said journal. The pawl-lever is oscillated by means of an eccentric e affixed to the shaft G and having its rod 6 pivotally connected with the pawl-lever.
I-I designates an inking-roller arranged above the printing-roller F and journaled in boxes 71, which are arranged in housings formed in the upper arms of levers H, which are fulcrumed loosely upon the journals of the printing-roller F. The lower arms of the levers H are connected by links 71 with arms 71, affixed to a rock-shaft h. Springs h fastened to the journal-box h and to the upper arms of the levers I-l, pull down the inkingroller H, so as to make it properly coact with the printing-roller F. One of the arms 7L3 is connected with the rod h of an eccentric 7L affixed to the shaft G, and this arm 71. is longitudinally slotted, so that the throw of the eccentric may be adjusted in its effect upon the lever H. Thus the length of swing given to the inking-roller H may be varied. The journals of the inking-roller II are provided withrollers 72, which, just before the levers H swing into a vertical position, ride upon small rollers h (shown in Fig. 7) and lift the inking-roll 1-1 against the resistance of the springs h outof contact with the printing-rollF, so that no action of either the printing-roll or the inking-roll will have any effect upon the other. While thus elevated the inking-roll II is inked by means of a distributing-roller I, which is rotated by means of a sprocket-wheel t', receiving a sprocketchain 2 which also passes around a sprocketwhee1t' affixed to the shaft G. Not only has the distributing-r0111 a rotary motion, but it has a slight longitudinal motion. This it derives from the coaction with a stationary upright pin 71 of a grooved cam 11", which is affixed to one of the journals of said ink-distributing roll. The ink-distributing roll I is supplied with the ink by a doctor-roll J, rotating in contact with it and having the ink applied to it by a knife or other suitable device.
Paper to be formed into a stencil-sheet is fed along, as already described, by means of the sprocket-wheels E, which operate intermittently through the ratchet mechanism e e, actuated by the eccentric 6 While in motion the bed-roll and printing-roll are also in motion, and the punch-bar O with its punches c are raised. After the paper passes these rolls'it is wound up on a take-up roll, one of whose journals 7c is shown in Figs. 5
and 6. As the paper accumulates it will have a tendency to tear unless some provision is made to obviate any excessive speed in the take-up roll as compared with the speed of the printing and bed rolls. To prevent any such'excessive motion, the journal of the take-up roll has a friction-disk 7o affixed to it, and with this friction-disk contacts another friction-disk 70 which is secured to rotate positively with a sprocket-wheel 70 deriving motion from a chain 70 which passes around a sprocket-wheel 10 which is affixed to the shaft G. As the disk 70 may slide or slip relatively to the disk 70, the take-up roll will be prevented from deriving excessive speed at any time from the friction-disk 71:
Whatl claim as new, and desire to secure by Letters Patent, is-
1. In a machine for preparing a stencil for mechanical music-sheets, the combination of a table having guides which coact with the edges of a stencil-sheet, punches for forming marginal apertures in the stencil sheet, toothed wheels coacting with the marginal apertures of the stencil-sheet, a step-by-step feed for said toothed wheels, a printing-roll for supplying rows of parallel dots to the stencil-sheet, and means for rotating the said printing-roll and supplying ink thereto.
