HENRY B. MORRIS, OF ITHACA, NEW YORK, ASSIGNOR TO THE AUTOPHONE COMPANY, OF SAME PLACE.

MACHINE FOR MAKING AND INSERTlNG STAPLES lN MUSIC- ROLLERS.

SPECIFICATION forming part of Letters Patent No. 339,679, dated April 13, 1886.

Application filed October-8, 1885. SerialNo. 179,371. (NomodvLl York, have invented a certain new and useful machine for inserting wire cams or staples at predetermined points into rollers intended for use in mechanical musical instruments, of which the following is a specification.

The leading characteristic of the machine is an intermittently-inoving pattern which governs the insertion of the staplesand determines their length.

As is well known, the shortest notes of such mechanical musical instruments as hand'orguns, orchestrions, 850., are produced by single pins projecting from the surface of a slowlyturning cylinder, which operate upon keys or valves to produce the tones. V Longer notes must be made by cam-surfaces upon the roller, of suitable length, so as to hold the keys or valves open for the proper time. Such a cam is commonly made of a wire bent into the form of a staple, its two points being inserted into the roller, and its middle projecting part being concentric with the surface thereof. The preparation of such staples of many various lengths and their correct insertion into the roller isa work requiring much labor and skill, and rollers so prepared are very expensive.

The object of this invent-ion is to provide mechanical means for making such staples and for driving them into the roller automatically and without the intervention of skilled labor.

In order that my invention may be clearly understood,l have illustrated and will proceed to describe a practical form of a machine adapted to insertstaplcs in a wooden roller along a spiral line.

Figure l is a plan view of the machine. Fig. 2 is a vertical longitudinal section in the plane indicated by the broken line 1 1 of Fig. 1. Figs. 3 to 10 illustrate details of the machine, some being drawn on a larger scale than Figs. land 2-, and others on the same scale. Fig. 11 is a plan view, partly in section, of the roller-can riage and its attachments, the section being taken upon the dotted line 2, Fig. 2.

The sameletters of reference indicate identical parts in all the figures.

The various parts of the machine are mounted on a suitable bed-plate or table, A, provided with the shear a across one end, for the support and guidance of the rear side of a sliding carriage, consisting of the upright cheek-plates B B and the parallel connectingbars B B B. The front side of the carriage is supported and guided by the bar 0, parallel with the shear a, said bar passing through holes in the cheek-plates B B, and being itself supported and held by the lugs O C" on the bed plate A, into which it passes. A horizontal roller, D, provided with projecting hubs at its ends, is arranged in suitable bearings between the cheek-plates of the carriage, 6 5 said hubs projecting through the cheek-plates B B and forming the journals of the roller. The parts of the hubs passing through the cheekplates are smaller than those adjoining the roller, thereby forming shoulders upon said hubs, 7c which prevent any lateral motion of the roller bet-ween the cheek-plates. The hub D projects beyond the cheek-plate B, and upon its outer end is rigidly attached the spur-wheel E. A shaft, F, journaled in the fixed bearing F on the bedplate, passes through the hub D into roller D, which is bored nearly its whole length to fit the shaft. A keyway, f, is cut in that part of shaft 13 which passes into the roller and hub, and the hole through which it so passes is provided with a corresponding spline, so that while said roller is turned by the shaft it may, with the carriage and the spurwheel E, move longitudinally thereon. The hub at the end opposite that entered by shaft 8 5 F is tapped or provided with a fixed nut to fit upon the screw H, which passes through, the hub into the roller nearly far enough to meet the end of shaft F. The outer end of the screw is rigidly secured to a standard, H, on the bed-plate A, or it may be so arranged as to be fastened and loosened at pleasure, so that the IOllvl and carriage may he slid along the ways by revolving the screw when the machine is at rest. Two rings, G G, of steel or other 5 hard metal, about equal in diameter to the roller D, are rigidly attached thereto at its opposite ends. The outer surface of the rings is roughened by line flutes formed therein parallel with their axis. Upon the surface of the rec roller between the rings is formed a deep squareshaped screw-thread, D, of the same pitch as the screw H. A longitudinal groove, D is also formed in the roller, extending from ring G to ring G, said groove being much deeper than screw-threads D which it intersects. Two parallel bars, I I, are fitted into the groove D and there secured by screwsat their ends, which screw into the roller. The outer surface of bars I I is curved, being flush ar d concentric with the 'top of screw-threads D I is a patter-n-belt, preferably made of a sheet of steel, which tightly encircles the roller D, and is riveted or otherwise secured by its ends to the bars I l, the body of the pattern-belt resting upon the tops of screw-threads D The pattern-belt is pierced with a series of holes, which govern the position and length of the staples to be driven into the musicroller; hence a separate pattern is required for each difi'erent kind of music-roller to be produced,- and said pattern may be readily changed by unscrewing the bars I 1 removing them with the belt I attached, and replacing them by another similar pair of bars, to which is fastened a different pattern-belt. A live-spindle, K, is journaled in the upper portion of cheek-plate B. This spindle carries a disk, K, at its inner end, and at the opposite end a fixed spur-wheel, L, of the same diameter and number of teeth as spur-wheel E, which drives it through the medium of an intermediate spur-wheel, L. The disk K is provided with a center pin, and also with a drive-pin,'K Gheelcplate B carries in its upper portion a dead-center, K screwed in the cheek-plate, so that it may be adjusted. The wooden roller M, in which the staples are to be inserted, and which I term the musicroller, is centered on dead-center K and central pin of disk K, one end of the roller being bored with an eccentric holeto receive the drive-pin K". It will be seen that the turning of shaft F has the twofold effect of feeding the carriage, together with the rollers D and M, and of revolving said rollers synchronously, so that they complete a rotation in the same time.

The devices for cutting and forming the staples and inserting them in the n1usicroller are mounted upon the stand N, erected on the bed-plate. A sliding head, 0, is mounted upon the stand, sliding in a dovetail groove formed in the top of said stand, in a direction parallel with the axis of the music-roller. The sliding head carries two sliding blocks, 0', O", which are fitted to parallel dovetail grooves in the top of said sliding head. Said sliding blocks move horizontally in a direction at right angles with the axis of musicroller. A vertical die-plate, P, is rigidly secured to the sliding head 0 on the side nearest the music-roller. In one side of the dieplate, near the top, is formed a notch whose lower side is horizontal, the upper side being inclined, preferably at about thirty degrees to the lower. zontal ledge of metal, p, on one side, the upper side of which ledge is even with lower side of notch.

Attached to the sliding block 0', is a tri angular punch, P, two edges of which fit the notch in die-plate P. The wire R, to be made into staples, is fed from a reel overhead, vertically downward, by a pair of feed-rolls; R R, mounted upon a standard, R erected on the bed-plate, said rolls being driven through the medium of a pulley, R, and a belt, by a pulley on the shaft 3. The feedrolls do not press verytightly upon the wire, so that when its advancing end strikes the ledge 19 its further progress is for the time prevented, the rolls revolving without advancing the wire, which, to prevent it from being bent, may, when necessary, be conducted through a small guide-tube nearly as far as the upper sideof the notch in the die-plate. The sliding block 0 is provided with a transverse dovetail groove near one end, inwhich a block, 0, slides horizontally, said block having a swageplate, O",'rigidly attached to it. One end of the swage'plate projects nearly across the face of punch P, and is beveled at same angle as the punch and notch in die-plate. The end of the punch is recessed to receive Plate P is provided with a horithe swage-plate, the bottom of said recess being curved, as is also the swage-plate, to the shape required to make the staples concentric with the music-roller when driven. The normal position of swage-plate is in about the same plane as the die-plate P.

The process of forming and driving astaple is as follows: WVhen the block Ois moved forward, the punch P cuts off the portion of wire extending across the notch in die-plate, pressing it at the same time against swageplate 0, to prevent it from flying away. The further advance of the punch causes the swage-plate O" to force the wire back into the recess in the face of the punch, bending it into the required shape, as is fully shown in Fig. 8. The staple is firmly held between the swageplate and punch, which advance together toward the music-roller, the block 0 being now driven by block 0' by means of stud O rigidly attached to block 0, and projecting into a slot in the side of block 0 said slot and stud being so arranged that the block 0 shall begin to movejust as the staple has been formed between the punch and swage-plate, in the manner just described, and also that the block 0 shall not be withdrawn beyond its normal position by the retreat of block 0'. When the staple has been advanced so far that its ends have entered the wooden roller beyond danger of its escape, the swage-plate O is suddenly withdrawn by means of the lever O centrally pivoted on block 0, havingone end engaged with sliding block 0 and being actuated by the stationary pin 0 upon the head 0, which pin is struck bythe outer curved end of the lever as the same advances with its block 0. The punch I now continues its advance until it has inserted the staple to a certain depth into the music-roller, when it is withdrawn by retreat of block to the place of beginning, the swageplate 0, block 0, and lever O returning to their normal positions, being influenced by the spring 0*, attached to block 0" acting upon the lever. More wire is now advanced by the feed-rolls and the punch is ready for another stroke. It should be remarked that the block 0' slides rather tightly in its groove, thus causing suffi cient pressure between the swage-plate and punch to insure the bending of the wire into the staple required. Since the wire is fed by the feed-roll always in the same line, and all the staple-forming devices above described may be moved laterally by sliding the head 0, which carries them, it follows that wires of different lengths may be cut by the beveled punch P and its corresponding die, depending for their length upon the position of sliding head 0, and as the swage-plate O is also beveled the shanks of thestaples when formed will all be of equal length, so that their outer curved portion alone will vary. Moreover, if the head 0 remain stationary after the wires are cut and while the staples are being driven, they will always be driven into the roller in the fixed plane of the feed-wire R.

1 will now proceed to describe the means whereby the insertion of the staples is governed by the perforated patternhclt. A line of shafting extends across the end of the bedplate opposite the rollercarriage, being suit ably journaled in standards erected upon the bed-plate. This shafting consists of two independent portions, S S, arranged in the same line, their place of separation being indicated by the dotted line S", Fig. 1. At the junction of the shafts S S is a clutch consisting of a disk-plate, S, fixed upon the end of shaft S, i

, loosely upon the roller-shaft F, and having large central hub, X". The hub X is confined and upon shaft S a larger circular plate, S", provided with an overhanging flange which encircles dislnplate S. A block, 'l, moves radially in a groove in the outer side of plate S being forced outwardly by an ellipticspring, T, acting against a pin, T", fixed in the block. A radial notch, T, is out through the flange of plate S, so that when block T is pushed outward by the spring it enters notch T and locks the plates together, causing them to re volve as one. The shaft S and plate S are revolved continuously by suitable motive power applied at the opposite end of shaft S, but

, shaft S remains at rest when the block T is forced centrally and prevented from engaging the notch. T. clutclrbar T centrally pivoted upon a stand ard attached to the bed-plate and operated by means hereinafter to be explained.

The clutch-bar T oscillates vertically and bears downward upon the pin of clutchi block T, so that when said bar is in its normal position, as shown in Fig. 3, the block is prevented from engaging with slot T As the block T revolves, being carried around by disk S", its centrifugal motion is prevented during This is effected by the.

most of its course by the overhanging flange of disk 5*; but when it arrives near the top the bar T, acting upon pin T forces the block farther in toward the center of disk than is needed to prevent its entering slot T hence the bar 1 may be elevated to a certain distance without allowing the clutch to lock. At each revolution of disk S a cam, S fixed thereon strikes a pin, T, on bar T, thereby depressing the bar beyond its normal position and immediately releasing it. The clutch-bar is connected at its opposite end by the vertical connecting-rod U with the rock-arm U, attached to rock-shaft U". Another rock-arm, U", is fixed upon said rock-shaft diametrically opposite U, and is connected by means of vertical connecting-rod U with the l'eeler-bar V, near the middle of said feelcr-bar. A standard, W, is erected on the bed-plate, to the upper part of which one end of feeler-bar V is pivoted, so that said bar may oscillate vertically.

Rigidly attached to the feeler-bar near its free end is the feeler, consisting of a short cylindrical bar, V, preferably of hardened steel, having upon its lower end a smaller cylindrical part, V which I call the point. WVhen the machine is not inserting staples, the point V rests upon the pattern-belt I on roller D, beingpressed downward by a spring, U on the bed-plate, which acts upon lower end of rod U, and through it influences the feelerbar V and all its connections just describednamely, rock-arms U U, roek-shaft U rod U, and clutch-bar T". This mechanism is so arranged that when the point V is resting upon the pattern-belt the clutch'bar is in its normal position, Fig. 3.

Upon the continuously-revolving shaft S is asmall tight pulley,X,which transmits motion by the belt X to a large pulley, X turning between two circular friction-plates, F and F upon shaft F, plate F being rigidly attached to shaft, and plate F, fitting loosely on the end thereof, being prevented from turning on the shaft by a spline. The hub X" is COID- pressed between frictionplates by means of a cupped spring, F", held and regulated by a screw passing centrally through said spring into the end of shaft F". Friction is thus produced between the hub and friction-plates suf ficient to cause shaft F to be turned by pulley X", except when otherwise prevented.

The perforations in the pattern-belt I consist'each of a narrow parallelsided slot, J, of predetermined length, terminating in a large circular hole, J. Said perforations are so located as to be directly over the grooves between the screw-th reads D of the roller D.

As before explained, the screw-threads 1) formed upon the surface of the roller D, are of the same pitch as the fecd-sercw H. The feeler-point V is situated directly over the spiral groove between the screwthreads on the roller.

The object of grooving the roller D spirally,

with the same pitch as the feedscrew, is that as said roller is fed along the screw H by its revolution thereon the screw-threads D shall maintain their relative position to the feelerpoint V",thegroovebetween two ofsaid threads being always directly under the feeler-point. This would not be the case if the threads D were of a pitch different from that of the feedscrew. The groove in the pattern-roller being thus always under the point aifords the latter sufl'lclent depth for its required descent through the holes in the pattern-sheet.

In operating the machine, the shaft F being turned, the rollers D and M are revolved and the carriage is fed along its guides. The feelerpoint V rests upon the pattern-belt, describing a spiral course thereon. \Vhen the feeler encounters a perforation in the belt, the point V at once descends into the narrow slot J as far as permitted by the larger part V above. The feeler-bar V also descends, and through its connection therewith the clutch-bar T is moved, so that the end of clutch-bar adjoining the clutch is elevated, not far enough, however, to permit the block T to engage the slot T; hence the clutch is not yet locked and the shaft S remains at rest. The feeler-bar is provided with a hook, Y, on its under side, supporting a horizontal rod, Y, parallel with the roller D. The ends of rod Y are attached to two pawls, Y Y, said pawls being centrally supported on studs in the cheek-plates of the carriage, which studs pass through central longitudinal slots in said pawls. Another rod, Y parallel with Y, connects the pawls Y and Y at their opposite ends, the two rods and the pawls thus forming a rigid frame. The ends of the pawls adjoining rod Y are adapted to engage the fluted rings G G on roller D. \Vhile the feeler-poiut V rests upon the pattern-belt I the pawls Y Y are held up by the hook Y out of gear with the fluted rings; but when the feeler-bar V is depressed by the descent of the point-into a slot, J, said pawls, being thus lowered, engage with the flutes in said rings, and are moved longitudinally by the continued rotation of roller D, the rod Y striking and driving before it the slotted cam-bar Z. This cam-baris provided with a longitudinal slot near one end, which end is supported by a stud, Z, fixed in standard V. The opposite end of cam-bar is beveled to correspond with a cam, Z attached to the sliding head 0, and is supported and held against said cam by a shouldered stud, Z, erected on the bed-plate. When by the progress of the roller D the point V reaches the end of slot J, the thicker portion V of the feeler enters large hole J, the point descending into the spiral groove between screwthreads D. This brings the friction driven rollers D and M to a standstill, the additional depression of feeler-bar Vresulting, through its connections with the clutch-bar T", in looking the clutch and the rotation of shaft S. Astaple is now formed and inserted in the music-roller, the block 0 being advanced and retracted by an eccentric, S, on shaft S, which actuates said block through the medium of the eccentric-rod S, rock-arm S wrist S and connecting-rod S. The wrist S is prolonged so that the engaging-eye of rod S may move lengthwise upon it when carried by sliding head 0, the opposite end of rod being snugly pivoted to block 0. When a staple has been inserted, the cam S strikes pin T momen tarily depressing it so far that through their intermediate connections the feeler point V is raised clear above the surface of the patternbelt, which, being no longer restrained by the feeler, at once proceeds to revolve. The point V is quickly allowed to drop upon the pattern-belt, and all the parts of the machine connected with it resume their normal positions, the sliding head 0 being returned by a spring,'0", upon standard N, and the cam-bar Z by spring W on standard XV. By the eledraws thepawls Y Y from contact with fluted rings G G, and the pawls are driven back to their first position by the retreat of the cambar.

It is obvious from the foregoing description that so long as the feeler-point rests upon the imperforate portion of the pattern-belt the frictioirdriven rollers D and M revolve and the staple-forming devices-remain at rest also, that the descent of the feeler V into a large hole, J, causes the rollers to stop and the staple devices to operate. It is furthermore plain that the entrance of the feeler-point into a slot, J, results in sliding the head 0. Since the length of a staple depends on the position of head 0, as before explained, and this in turn depends upon the distance to which the cam Z and cam-bar are moved by the pawls Y Y, it follows that the presence of a long slot, J, in the pattern-belt will cause more motion of the head 0 than a short slot would do, and consequently the formation of a longer staple; hence the length of each staple will be in direct proportion to the length of its corresponding slot in the prearranged pattern-belt. The punch P does not drive the staples quite to their destined depth in the music-roller, thereby avoiding the danger of driving too far any previously-driven staples with which it may come in contact, but all the staples may be subsequently reduced to a proper depth by revolving the music rollerin another machine against a hardened pressure-roller, or by any other convenient method.

In order to perform most pieces of music, single pins are required upon the music-roller as well as staples. Such pins may beinserted before or after the staples, either by hand or by automatic machinerysuch, for instance, as that for which Letters Patent were granted to me April 7, 1885, N o. 3l5,0520r the pi n'driving devices therein described may be combined with this machine, so that a roller may be furnished with both pins and staples by the same machine. This I regard vation of the feeler-bar V the hook Y with as a mere modification of my invention, and" many other variations may be made withoutdeparting from the principles of my invention. For instance, to adapt the machine for preparing rollers having circular rows of staples and pins, the screw-feed may be so modified as to advance the carriage a distance equal to that between two adjacent rows at the completion of each full turn of the pattern-roller, parallel circular grooves being substituted for the spiral grooves in said roller.

I believe that I am the first to provide a machine for automatically inserting staples in music-rollers in accordance with a previouslyprepared and intermittently-moved pattern, and therefore claim such machine broadly. As regards the pattern, its form maybe much varied. Thus, instead of using a changeable pattern-belt upon a roller, a separate roller may be provided for each kind of music-roller having depressions corresponding with the perforations, or the pattern nny consist of a plane surface with perforations or depressions, suitable changes being made in the feeler and other connections.

I claim as my invention 11.. A machine for making and inserting staplcs in music-rollers, organized with an inter n'iittingly'moved pattern, which governs the length and position of the staples, substantially as described.

2. A machine for making and inserting stapics in music-rollers, organized with an intermittingly-inoved pattern, which governs the position and length of the staples, said pat tern being moved by a friction-feed, SLlbSh2llltially as set forth.

3. In a machine for making and inserting staples in music-rollers, the combination, substantially as set forth, of the feed-carriage, feed-screw, and pattern-roller, the said roller having its surface spirally grooved with the same pitch as the feed-screw.

4. In a machine for makingand inserting staples in nuisic-rollers, the combination, sub stantially as and for the purposes set forth, of a grooved pattern-roller with a perforated pattern-belt, said belt encircling the roller and havingdts perforations opposite said grooves.

5. The combination, substantially as described, of a perforated pattern-belt encircling a friction-driven roller, with a feeler point arranged to press upon said patternbelt and to detain the roller by engaging with a perforation in said pattern-belt.
