MACHINERY FOR INSERTING STOPPER-RETAINERS INTO BOTTLES.

SPECIFICATION forming part of Letters Patent No.495,640, dated April 18, 1893.

Application filed May 19, 1892. Serial 110,433,595- (No model.)

To all whom it may concern:

Be it known that I, ARTHUR J. SANDS, a citizen of the United States, residing at Merton, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Machinery for Inserting Stopper-Retainers into Bottles and other Vessels; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to machines or apparatus for automatically inserting into the necks of bottles and other vessels, fastening plates or bars of sheet metal so that the edges of saidiplates or bars shall be caused to engage an internal shoulder in the neck of said bottle or other vessel, above the cork or stopper proper thereof, and thus retain the stoppers in the necks of the bottles. In Letters Patent No. 409,374, issued to Josias J. Sands on the 20th day of August, 1889, is described and shown a retainer or fastener of the above described type for inserting which my invention is designed and adapted, said fastener consisting of a slotted arch with lateral extensions at the bottom thereof.

Fig. 26 is a horizontal cross-section thereof on the line 26-26 of Fig. 25. Fig- 27 is a transverse vertical sectional view of the neck of a bottle as it appears after the retainer has been inserted therein.

A is the table or base of the machine, made of any desired material and of such thickness as will insure necessary strength. This table is supported upon suitable legs, A, of such length as will raise the operating parts of the machine sufficiently to admit of their being conveniently accessible to an operator standing on the floor.

Power for operating the machine is imparted through the positively driven shaft, B, having hearings in lugs or brackets, I), depending from the under side of the frame or table and driven by the pulley B. That the machine may be quickly and conveniently started and stopped, the driving pulley and shaft are connected and disconnected by a suitable clutch, so that they can be engaged and disengaged and the machine thus started or stopped by a movement one way or the other of the clutch lever B in a familiar manner.

At the back of the machineis a stationary, rectangular hopper, (3, which contains the fasteners or retainers for supplying the machine, said hopper being elevated above the frame or table of the machine and supported on posts, 0. For reasons hereinafter apparent, the hopper is provided in the middle of its bottom with a longitudinal slot, 0, the side walls 0 o of which are made of some considerable depth, and its bottom is formed by two inclined surfaces, 0 sloping toward said middle slot 0. For the purpose of additionally strengthening and stiffening said hopper, flanges, formed by downward extensions, c of the sides of the hopper, and a false bottom, connecting said extensions of the sides with the side walls 0' o of the slot, are provided.

Oscillating in a vertical plane through the slot in the bottom of the hopper, is a delivering device for taking fasteners from the hopper and delivering them to the expanding or inserting devices arranged in position to be operated upon thereby, said delivering device consisting of aplate D, of segmental or approximately triangular form, having on its upper edge a rib or tongue, d, so shaped that the central arch of the U-shaped bend of the fastener will fit thereon. As the delivering segment, thus constructed, rises through the mass of loose fasteners or retainers in the hopper, the arches of some of said fasteners will in all cases engage or catch upon the tongue on the segment so as to straddle the tongue and be raised with it. This delivering segment, as it will for convenience hereinafter be termed, is pivoted to a standard, d at the point d near the apex thereof and with said apex adjacent to the expanding or inserting devices of the machine; the pivotal point being practically on a line with the bottom of the hopper and at such an elevation that the fasteners delivered to the chute, hereinafter described, will descend by their own gravity along said chute to the inserting mechanisms. Vibratory vertical motion is imparted to said delivering segment by means of a cam, D, upon the periphery of which the under surface, d of the delivering segment rests. This cam is carried on a shaft, D having hearings in lugs or brackets, (1 depending from the under side of the table or frame of the machine. Said shaft D is actuated from the main driving shaft by a spur gear, D on the driving shaft, which intermeshes with another spur gear, D secured to and revolving with said driven shaft carrying the cam. It is obvious that the vibrations of the segment can be regulated by changing the relative size of the gears D and D on the driving and driven shafts.

The relative sizes of the delivering segment, D, and of the cam D, and the relative positions of the hopper, the pivotal point 61' and the shaft D should be such that when the segment is at its lowest point the upper edge thereof will be flush with the upper edge of the slot in the bottom of the hopper and parallel with the bottom of said hopper, and when at its highest point, the upper edge of said segment will be so inclined that the fasteners resting thereon will slide by gravity toward the pivotal point cl. In order to permit the oscillation of said delivering segment, a vertical slot, D is made in the front wall of the hopper. This slot is closed by means of a gate, D vertically movable in ways, d formed in the said front wall of the hopper. A spring, (Z serves to hold the lower edge of the gate D, in constant contact with the upper edge of the delivering segment D and a slot, (1 is provided in the lower edge of said gate, of such shape and size as to permit the passage through it, one at a time, of the retainers, as they descend along the delivering segment. Thus the front of the hopper is always kept practically closed, while at the same time provision is made to permit the oscillation of the delivering segment and also to permit the passage of retainers therealong. The gate D is wider than the delivering segment, and in order that it may follow the segment to the bottom of its stroke, the laterally projecting portions of its lower edge are beveled as at d to correspond with theinclination of the bottom of the hopper. The slot in the lower edge of the gate D being only large enough to allow the passage of a single retainer at a time, means are provided to prevent other retainers in the hopper from lodging or catchin g on those retainers which are in proper position, on the rib of the segment, to pass through said slot. The means shown comprise a brush, E, pivotally supported from a bracket, E, attached to the inside of the front wall of the hopper, by means of a pin, 6, bearing in said bracket and loosely fitted to a hole, 6', in the block, E which latter is rigidly secured to the back of the brush.

The front wall of the hopper, upon which the bracket E is supported, is not made integral with the adjacent parts of said hopper, but is loosely fitted thereto and is adapted to move backward and forward longitudinally of said hopper, suitable means, hereinafter described, being provided for giving reciprocatory movement thereto, and such movements serving to actuate the clearing-brush E, and also to aid in the passage of the retainers through the front of the hopper.

Projecting laterally from one side of the block E is a pin, 6 adapted to engage with the cam surfaces, 6 and e, of a block, E which is secured to the side of the hopper in proper position. The position of said cam surfaces e and e and of the pin 6 relative thereto, is such that as the brush moves backward, that is to say, toward the rear end of the hopper, the free end of the pin will engage the under surface 6 of the block E in such manner as to cause the brush to come into contact with those retainers which are entangled with the retainers upon the segment, and thus to swing to one side and at the same time remove the entangled retainers. Just as the brush reaches the rearward limit of its movement the pin passes out of engagement with said cam surface e and the brush is raised out of contact with the upper side of the delivering-segment, and being released swings down of its own gravity. The adj ustment of the parts is such that as the brush is at the rearward limit of its movement, the segment D is at the upward limit of its movement. Thus the brush is released just as the segment is at the highest point and when their relative positions are such that as it passes backward over said segment it will as above stated brush off all retainers excepting such as are in position to pass through the slot in the gate. On its forward stroke the pin 6 engages the upper cam surface 6 along which it passes until it reaches the forward limit of its movement when it passes out of engagement therewith and swinging down by its own gravity is in position to again engage with the under cam surface 6 as the brush is again rearwardly moved. This operation is repeated at each vibration of the delivering segment.

The block E on which the cam surfaces 6 and e are formed, is pivoted at e upon a bracket E which proj ects inwardly from one side of the hopper, and on the lower cam surface e a shoulder, (2 is formed with which the pin 6 comes in contact shortly before the brush reaches the rearward limit of its movement and is released. Simultaneously with the pin 6 striking the shoulder a, the brush comes into contact with a stop, 6 adapted to arrest its lateral or radial movement. As a result of this construction the cam-block E is rotated on its pivot against the action of a spring, E adapted, in combination with a stop formed by a shoulder, a on said block and a surface, a", of the rigid piece on which said cam block is pivoted, to maintain said cams in proper position to insure the proper engagement of said cams with the pin 6 When the pin passes out of engagement with the cam, 6 the spring E forces the cam block E downward into its usual position, thus insuring the engagement of the pin 6 with the upper surface 6 on the return stroke of the brush and the desired operation of the parts.

Reciprocatory movement is imparted to the loose front end of the hopper from the shaft D in the following manner: The said movable end wall of the hopper rests upon the bottom thereof and has cylindrical standards, E projecting forward through circular guide holes in a guide plate E. These standards also act as links and are connected with levers, E, which are securely attached to the pivoted bar, E bearing in the upright brackets, 6 At one end of this pivoted bar is secured in any suitable manner, one end of a lever, E the other end of which is connected with a crank-arm E upon the shaft D by a link a. It is obvious from the relation of the various parts above described that each revolution of the shaft D will cause the loose front Wall of the hopper and the brush carried thereon to vibrate forward and back, and

will thus, as above stated, properly actuate the clearing-brush, and also aid in the proper discharge of the retainers through the front of the hopper.

As the fasteners carried on the delivery segment descend along said segment they are discharged into a chute, F, at the upper end of which said segment is pivoted in such manner as to insure the free passage of the fasteners from the segmentto the chute, the rear end of said chute being supported upon a standard, d The fasteners descend along this chute to the inserting mechanism by the action of gravity. Said chute is formed of a part or bar, F, the external surface of which is of inverted Ushape, in cross-section, and over which the arches of the fasteners pass, said bar having flanges, f, at the bottom thereof and at right angles thereto, on which the ends of said fasteners rest. Said fasteners are-prevented from falling or being thrown from said chute by guards, f, preferably made of strips of light metal bent at right angles or into approximately U-form and secured to the outer edges of the flanges, f, so that with said flanges they will form a groove into which the outer ends of the retainers will extend when their arches are properly adjusted to the arch of the chute, thus rendering it impossible to remove a fastener or retainer from said chute during its passage along the same. Near the lower end of the chute and so placed or adjusted that it will strike the tops of the fasteners in the chute, as they pass under it, is a revoluble brush, F carried on a short shaft, f having a vertically adjustable bearing on a bracket, f secured to the top of the machine table or frame. On the other end of this shaft is a pulley, f driven by a crossed belt from another pulley f, secured to the shaft, D so as to revolve therewith. Having descended by their own gravity along the chute, when they come within the influence of the revolving brush, the fasteners are by it pushed along to the lower end of the chute and to the inserting devices.

In order that the operation of those parts of the machine which are more immediately concerned in the inserting of the retainer, and now to be described, may be more readily understood, I have shown in Fig. 24, a fastener of the kind which the machine is intended to operate upon. A indicates such fastener, the same having a central arch, a, and flat outwardly and laterally projecting end portions, a, a, which are adapted to engage the groove in the bottle neck by the spreading apart or expansion of the sides of the arch. The said arch is provided with a central longitudinal slot, 61?, parallel with the sides of the retainer, and the ends of which are located near the end portions a a of the retainer, so that the arch ma be expanded by means engaging the ends of the slot and pressing outwardly against the same.

The inserting mechanisms are all supported upon an upright frame formed by standards, G, united at its base to a bracket, G, depend ing from the under side of said main frame. Sliding vertically in ways orguides, g, on said frame is a cross-head, G held normally at its upward limit of movement by means of coiled springs, g, which are compressed as the cross-head descends and which in expanding again restores the cross-head to its raised position. This cross-head is actuated by a lever G pivotally supported between its ends at the top of a post or pillar, G secured to the main frame or table of the machine. The rear end of this lever is connected by a link, G with the forward end of the lever, G pivotally supported at g on a bracket, g depending from the under side of the main frame of the machine, the rearward extension of said lever G being so located as to be acted upon by a cam, G securely attached to the main driving shaft B and revolving therewith. It is thus evident that at each revolution of the shaft B the rearward end of the lever G will be depressed by contact of the cam G therewith and, through the intermediate connection described, the forward end of the lever G will also be depressed.

Pivotally supported upon the cross-head G at h, so as to move up and down therewith, are levers, H. The lower ends of these levers are held normally together by means of a spring, h, interposed between said levers above their pivotal points. Jaws or nippers 71 are formed on the lower ends of these levers which, when said levers are in their closed position, are adapted to enter the slot of a retainer supported in proper position thereunder, and to engage the shoulders at the ends of the slot of the retainer with sufficient force to secure said retainer in position upon said jaws, so that it will be supported thereupon, when its lateral supports are withdrawn. These levers are maintained in proper position to secure their intended operation by means of guide-bars, H, secured to the face of a plate, H said plates being provided with guide slots through which said levers play, enough room also being left between the ends of the slots and the levers to permit of the outward movement of said levers necessary to expand said retainer so carried on the jaws 7?. When the jaws or nippers 7r have entered the slot of the retainer so that it will be held thereon, the retainer is released, as hereinafter described, and is carried downward with said levers into the neck of the bottle or other vessel in which it is to be inserted and which is supported in proper position thereunder. When the fastener has been carried down to a point where the ends of said retainer are opposite the internal annular groove in the neck of said bottle or other vessel, the jaws 71 are forced positively apart so as to expand the retainer, by means as follows: A cam, H

is fitted to a slot, 71, formed between off-set portions, 7%, of the levers H. The cam H has a central pivotal shank, k bearing in the plate H and projecting rearwardly through said plate. Rigidly secured to the other end of the shank 77, is a lever, H the free end of which is engaged by the front end of a lever, H pivoted between its ends to the pillar G The rear end of this lever is connected by means of a link, H, with the forward end of a lever, H the rear end of which is so adjusted as to be depressed by a cam, H secured to and revoluble with the main driving shaft B. The adjustment of the various parts is such that the cam H will depress the lever and thus rotate the cam H when the ends of the retainer in the jaws 71 are opposite the annular groove in the neck of the bottle. The shape of the cam H is such that as it turns, it will force the levers H equal distances in opposite directions. A spring, H acting upon the lever H serves to return the cam 11 into position so that the levers H may come together as soon as the cam passes out of engagement with the lever H The degree of separation of the jaws or nippers will be such that the ends of the fastener or retainer carried thereon will be expanded or forced apart, and thereby caused to enter the annular groove in the neck of the bottle. The various parts of the inserting devices are so adjusted that this expansion shall take place at the lowest point of the stroke of the cross-head and just before the nippers are withdrawn or retracted to their normal position. As said cross-head and levers are raised by the action of the springs g the shoulders 77, at the bottom of the slot formed by the off-sets in said levers, come into contact with the lower surface of the cam H the relative positions of which determine the limit of upward motion, which need be such as to raise the lovers only sufficiently to allow a fastener to pass below them into position to be engaged thereby at the next operation of the machine. As the fasteners in the chute are forced forward by the brush F the foremost fastener'will be pushed out of the chute and the end thereof inserted into the slots 11 in the jaws I; said fastener being forced outward until its outer edge strikes against the plate t" by which its further advance is prevented; said fastener being then in position to be engaged by the inserting mechanisms. The jaws I are movable laterally in guide ways formed between the face of the plate H and the plate 0;, said latter plate being supported in position by its ends 71 which are turned forwardly at right angles, and attached to the edges of the plate H In their movement in and out in said guide-way, said jaws rest upon the plate Z, secured to the lower edge of the plate H and hereinafter fully described; said plate Z acting also as a stop to arrest the upward movement of the bottles and to support them in proper position to be operated upon. The middle portion of said plate Z, is cut away sufficiently to permit the unobstructed downward passage of the inserting levers ITO and fasteners carried thereon, also as hereim after described. For actuating the sliding jaws I I, levers, I, I, are pivoted upon the front of the upper guide bar and have their lower ends connected with the slotted supporting jaws by means of studs, i i passing through slots, 2' 41 in the lower ends of the levers and secured in plates, 1 1 which are attached to the top surfaces of the said supporting jaws.

The jaws I I are held normally at the inner limit of their movement by means of the coiled springs 03, (see Fig. 17) their inward position being determined by the screws t threaded into the outer ends of said jaws and passing through the end walls 2' of the guide ways, the heads of said screws being adapted to strike against said end walls of said guide ways and to arrest their inward movement. The extent of their inward movement may be adjusted within certain limits by turning the said screw 6 in or out. Said screws also form guides for the coiled springs 17*. The inward or normal position of the jaws is that at which they are located when in proper position to receive fasteners from the chute and hold them in position for engagement with the inserting levers. For operating thelevers I I to move the sliding jaws, a pin 1' is inserted in the cross-head so as to project forward between the inserting levers H and into the plane of the said levers I I and the latter levers are crossed at their pivotal points and provided at their upper ends with beveled surfaces t t adapted for engagement with the pin 1; as the latter is moved vertically downward with the cross-head; the action of the pin on said beveled surfaces being to thrust the upper ends of the levers I I outwardly and thereby move the lower ends of the same outwardly; such outward movement of the lower ends of the levers arising from the fact that the same are crossed, as described.

Working in the slot j at the back of the plate H and pivotally attached to one post of the standard G, is the lever J, which is held normally with its inner end elevated by means of a catch or stop j, and which is so situated that it may be lowered by hand into the path of the retainers in the chute by force applied to the outer end thereof and thus prevent the delivery of fasteners to the slots in the supporting blocks whenever it is desired to stop the forward movement of the retainers. During the process of insertion the bottle rests upon a support, K, on which it is raised till its top strikes the under surface of the plate Z, which is the position of the bottle for the insertion therein of a fastener or retainer by the machine. This support consists of a horizontal plate, 75, having a semicircular vertical flange, Zt",thereon,which indicates the proper position on said support for the bottle to be operated upon. the top of a vertical rod, K, passing through a guide hole, k in the bracket table, K This rod is fitted within the bore, 710 of the This support is carried upon sleeve K in which it is free to move up and down, and is supported by a coiled spring, K resting on top of the sleeve K and retained in position by means of a collar, 10*, which is secured to the supporting rod by a set screw, and by means of which the support for the bottle may be raised or lowered relatively to the sleeve. At the top of the sleeve are stopscrews, 7.0 which limit the play of the supporting rod relatively to the sleeve said stop screws being adapted to strike the shoulders or head k formed on the lower end of said supporting rod. The sleeve K is screwed into the upper end of a link K and is connected by means of the said link, K with the pedal, K pivotally supported at 10 by the rod 766. This rod bears in the bars K secured to the legs of the machine. It is thus obvious that as a bottle carried on the supporter is caused to strike against the plate Z by the appropriate movement of the pedal, a yielding contact is obtained, which is very desirable.

In order to secure the proper operation of the inserting mechanisms, it is essential that the mouth of the bottle, into which the retainer is to be inserted, shall be held centrally beneath the inserting levers. To effect this a centering device is provided. This device consists, as herein shown, of two jaws, L, lateral-ly movable in horizontal ways, 1, formed by the downwardly and inwardly turned edges of the plate, 1', which is secured to the under surface of the plate H said plate Z being provided with a suitable hole to permit the passage of the inserting levers and said jaws being provided with symmetrical, upwardly tapering, semi-circular recesses, L, in their lower surfaces and adjacent sides, adapted to form an upwardly tapering recess, circular in cross-section when the jaws are closed. The jaws are held normally with their adjacent sides together by means of springs, L located between the outer ends of the jaws L and plates Z secured to the standards G; said springs being maintained in position by means of guide pins, Z secured in the plates Z Pins, 1*, one secured in the side of each jaw adjacent to the standards G, engage slots, Z formed in a plate, L pivotally supported in the base of the standards G by means of a pivot shank, Z. The relation of the pins Z and the slots Z is such that rotary movement of said plate will cause said jaws L to move equal distances in opposite directions and such also that a lateral movement of either of said jaws will rotate said plate. It is thus evident that a movement of either of said jaws L will'produce an equal movement of the other jaw in the opposite direction. Thus,

whether together or separated, saidjaws will operate as a centering device to bring the mouths of the bottles in proper position relative to the inserting jaws. It is also obvious that the machine is by this construction adapted to operate upon bottles the mouths of which are of diliferent sizes.

IIO

As each operation of the levers I-I expands a retainer, it is desirable in order to prevent waste of retainers, that said levers shall operate only when a bottle isin position to receive a retainer. To prevent the operation of the inserting device under these circumstances, means are provided as follows: The lever G instead of bearing directly upon the crosshead G rests upon thehead of a pin, m, fitted to and vertically movable in a hole, m, in said cross-head. A spring, 077, bearing upward against a nut m on the upper end of said pin m serves to keep it normally at the upward limit of its movement, and said lever is held in place upon the head of said pin by means of projections, m extending upward from the top of the cross-head, one on each side of said lever. A horizontal slot or groove, m is formed in the cross-head just below the lower end of the pin m, when both said pin and cross-head are at the upward limit of their movement, said slot or groove intersecting the hole 'm in which the pin m slides. Fitted loosely to this slot and pivoted to the cross-head at one end is a baror lever M, (see Figs. 18 and 19) which is adapted to be moved into and out of the path of the pin m. A spring, m tends to maintain the bar M in position to engage the lower end of said pin m, but this tendency of the spring is overcome by a catch, m formed on the lever M, which is pivoted at its lower end to one of the standards G, as shown; said standard being recessed to make room for said lever. A spring, m holds the lever M at the outward limit of its movement, which position is determined by the relative positions of the end of the bar M and the adjacent edge of the lever M. This outward position is such that the catch m will project beyond the adjacent end of the bar M. From the construction shown it is obvious that when the lever M is sufficiently retracted to release the bar M, the spring m will force said bar into position to arrest the downward movement of the pin m so that the further movement of said pin will operate to depress the cross-head G The catch an forms an upwardly and rearwardly inclined cam surface, and is of such length and is so located that when the cross-head is fully depressed the upper surface of the bar M will be below the lower end of said catch. The relative positions of the catch m and of the surface m of the bar M are such that when the cross head is at the lower limit of its movement and said catch in its normal position, the lower edge of the cam surface forming said catch will be in position to engage the surface m of the bar M; thus, as the cross-head rises, the cam surface forming the head will operate to retract the bar M out of the path of the pin m, and further operation of the driving devices will produce no other result than depressing the pin m in the hole m until the bar M is again released. The release of the bar M so as to again engage the pin m at the proper time, and of the lever M bar Mas the cross-head rises.

on which the catch m is formed so that it will be in position to retract the bar M as the crosshead rises, is efiected in the following manner. Pivotally connected with the lever M is a link, M which passes through a guide slot, m formed in the standard G, to WlllCll the lever M is pivoted. The vertical arm of a bell-crank, M pivoted to a lug on said standard G is connected with the free end of the link M by a tripping connection, said link and lever being held in engagement by means of a spring, M The horizontal end of said bell crank is connected by means of a link, M with the outer end of a lever, M pivoted between its ends to the lower end of the standard G in such manner that the free end thereof will project into the circular recess L formed in the lower surfaces of the centering jaws L, so as to be engaged and raised by the top of a bottle as it is being placed in said machine. As shown in the drawings, the lever M is pivoted to the side of a groove or recess, 9 formed in the standard G, so that it will be out of the way of the other operating parts. When opposite the center of the centering recess, the end of the said lever is turned at right angles thereto bringing it in position to be operated upon by the bottle in the manner described. The jaws, ways and standard are cut away to permit the operation of said lever. The position of the lever M and the parts actuated thereby will be such that shortly before said lever reaches its upward limit of movement, the catch m will be sufficiently retracted to release the bar M, and such also that after said bar has been released and just as, or just before, said lever reaches its said upward limit of movement, the connection between the link M and the bell crank M will be tripped allowing the catch m to be returned to position to engage the A spring, M serves to hold the inner end of the lever M normally depressed and also to cause the end of the bell crank M to engage the link M thus maintaining all parts normally in position to secure their desired operation.

To now describe the operation of the inserting devices: it will be assumed that the crosshead is at the upper limit of its stroke and just about to descend and that a retainer is in position in the supporting jaws to be engaged by the inserting levers. A bottle is placed upon the support K and is raised into position to receive a retainer. As it passes upward it strikes the inner end of the lever M, which through the intermediate connections described, retracts the catch lever and releases the bar M, which is forced by the spring on into the path of the descending pin m, thus operating to depress the cross-head. When said cross-head has been depressed so that the nippers on said levers are made to engage the retainer held in the sliding jaws, the pin 7; on the cross-head comes into contact with the beveled surfaces 47 at the upper ends of the levers 1 thereby forcing said jaws apart and releasing the retainer. Just as, or slightly before, the inserting levers reach the lower limit of their movement, when the retainers carried thereon are opposite the groove in the neck of the bottle, the cam H is quickly actuated by the connections heretofore described, so as to force said levers apart and expand the retainer. The cross-head is then raised and the bar M retracted by engagement of its end with the cam surface of the catch m the lever carrying said catch having tripped its connection with the bell-crank actuating it and having been returned to position for engagement with said bar M by means of the spring m No further operation of the inserting devices will then take place until the lever M is again released so as to re-engage the bell-crank and the link M I claim as my invention.-
