SPECIFICJAI'ION' forming part of Letters Patent No. 381,339, dated April 1'7, 1888.

Application filed December 2, 1887. Serial No. 256,798. (No model.)

To all whom it may concern:

Be it known that I, CLEMENT COLERIDGE CLAWSON, a citizen of the United States, residing at Newark, in the county of Essex and 5 State of New Jersey, have invented .certain new and useful Improvements in Coin-Con trolled \Veighing and lVeight-Prinl'ing Machinery, of which the following specification is a full, clear, and'exact description.

[ This invention relates more particularly to machinery whereby a person may receive, a

- ticket printed with his weight on depositinga proper coin or coins in the machine, and it is designed as an improvement upon or modifir cation of the machine described in my Patent No. 366,303, granted July 12, 1887; but the several improvements constituting the said invention may be embodied in any machine to which they are or may be applicable.

The invention comprises, first, certain improvements in the means for supporting a lever, a drum, or other rotatory device, through which pressure is conveyed to a counterpoise whose force or counterbalancing effect increases with the motion of said rotatory device. A counterpoise of this kind is described in said patent, it being composed of a series of weights which are successively lifted by the rotation of a drum. There are also other known forms-- 0 as, for example, first, a spring or springs whose tension increases as they are retracted; second, a weighted leverarmwhose power increases as the lever-arm swings upward or from side to side; third, a weight or spring 5 combined with a cam in such manner that they act a greater distance from the center as the cam is turned; fourth, the converse of the last mentioned, where thepower to turn the rotatory device acts at a less distance from the 40 center as the said device is turned under the influence of said power, and so on,

The improved means are to be combined with any counterpoise of the character de-' scribed, but specially with a series of weights. 5 The improvements in these means are, (6a,) the combination, with the rotatory device, of a double bearing-namely, a bearing without sliding friction-mud a pivot-bearing whereof one part turns in or on the other, the two bearings being so arranged that when the limits of the nonsliding bearing are reached the rotatory device may turn on the pivot; (b,)the formation of a bearing without sliding friction by means of a fulcrum'piece or fulcrumpieces having a bearing surface or surfaces of convex curvature and resting upon a level or nearly level stationary bearing surface or surfaces whereon the said fulcrum piece or pieces may roll back and forth as the rotatory device is turned in one direction or the other; (0,) the formation of the double hearing by means of a j ournalor journals which are free to roll upon a stationary bearing surface or surfaces of limited length and are also capable of turning as pivots at the ends of said surface or surfaces where its or their traversing motion is arrested by stops, hollowed out or not, as may be desired.

Bearings without sliding friction are not, or at least the knife'edge and rolling bearings 0 heretofore made have not been, well adapted to use in connection with counterpoises of the character specified where a large angular motion is desirable and where a balance takes placeinvarious positions of therotatory device. 7 5 Pivot-bearings are otherwise well adapted to such use; but the sliding friction between the surfaces is apt to render the balance inexact. The combination specified under (a) avoids the difficulty by bringing the non-sliding bearing into action when the balance is secured and allowing the remainder of the movement to be accommodated by the pivot-bearing, whose slight friction is not specially objectionable except at the time of balancing. 8

When a person steps on the scale, or an object is placed thereon, the weight on the scale turns the rotatory device against the force of the counter-poise, let us say, beyond the limits of the non-sliding bearing, thus turning it also 0 in or on its pivot-bearing. This motion, owing to the action of the acquired momentum, carries the parts beyond the position of balance, so that as soon as the motion is arrested a reverse motion takes place under the influence of the counterpoise. During this reverse motion the rotatory device first turns on the non-sliding bearing, and then, if necessary, on its pivot, until having been carried a certain distance (less than before) beyond the posi- ICO in the cardbox.

tion back and forth continues the movementat each reversal becoming less and less, until the non-sliding bearing suffices to accommodate the motion, and finally the parts come to rest and a balance is secured without fiction, or practically so.

Although a rolling bearing is specially included in the above combination of (ca) yet the latter is not limited to that form of non-sliding bearing, but covers generally the double bearing operating in the manner described.

The improvements above specified under (b) is believed to be new, and is included in the invention whether there is or is not also a pivothearing.

The invention comprises, secondly, certain improvements in those printing mechanisms which have a movable form or series of type mounted on ayielding support orsupports, so that they can be separatelypushed out, in combination with a printingfinger which is independent of the means for adjusting the form or type, and is advanced after the type have been adjusted, to bring the proper character or characters in position in order to give the impression. Printing mechanism of the character specified, in combination with balancing mechanism, is described in the Patent No. 366,303, before mentioned,and my applications No. 235,672, filed April 21, 1887, and No. 240,507, filed June 7, 1887. It is also known outside of such combination,in different forms, in typewriting machines forgeneral purposes. It is old in such mechanisms to have notches, teeth, or some substitute therefor, which are engaged by the printing-finger, so as to prevent independent motion of the type in printing.

The present improvements in the printing mechanism are, ((1,) the attachment of the holding-teeth to a flexible support or band of soft vulcanized rubber or other like material, on which the series of type are mounted, instead of to a rigid frame carrying such band, or to the backs of separate type each on its own support; (1),) certain combinations of inking and guide rollers, with movable type which can be pressed out to print, and especially a rubber printing-band with or without holding-teeth and with or without side flanges.

In the weighing-machine the type are connected with the balancing mechanism, so as to be adjusted or controlled thereby.

The invention comprises, thirdly, certain improvements in mechanism for delivering cards to be printed from an upright card-box to a printing mechanism, which gives the im pressions by a horizontal motion or movement parallel or nearly so with the cards as they lie An arrangement of thiskind is described in my application for a weighing and weight-printing machine, filed April 2t, 1887, No. 285,672, the cards being taken sue cessively by a feed-roller having teeth which catch the cards and carry them downward inside a curved case. The present improvements under this head are, (0,) the combina tion, with the card-box and the printing mechanism, of a horizontally-reciprocating pusher and a curved disch argepassage extending from the side of the card-box opposite the end of the pusher and curving downward, so as to bring the face of the card opposite the printing-type; (1),) the formation of one side of the curved passage in the combination mentioned by the periphery of a roller, which is free to turn with the cards as they are advanced by the pusher.

In the weight-printing machine the printing-type are adjusted or controlled by the balancing mechanism, and the printing is effected by the operation of a printing-finger, which pushes out the appropriate type.

The invention comprises, fourthly, a certain improvement in means for effecting the control ofany suitable weighing and weight-printing machine by the introduction of coins or tokens. This improvement consists in the combination, with balancing mechanism, a deteut or lock therefor, and printing mechanism having the printingtype adjusted or controlled by said balancing mechanism, of a powerdriven mechanism, which operates first to release or unlock the balancing mechanism and afterward works the printing mechanism, and a coin-motor which directly or indirectly controls the operation of said power driven mechanism.

A mechanical power or clock-work is especially intended by powerdriven mechanism here and elsewhere in this specification, but other known or suitable powers may be used and are included.

The invention comprises, fifthly, certain means whereby in coincontrolled machinery using a mechanical power-driven mechanism the introduction of coins is prevented when the power -driven mechanism is run down. These means consist of a shutter movable to close the coin slot or leave it open, according to the position of said shutter, and operating mechanism having an arm or other ap propriate device at a suitable point in the path of the operating weight or of other suitable part of the power-driven mechanism, so that it is struck thereby when the power is exhausted or nearly so and moves the shutter in the direction to close the coin-slot, the said shutter being held back at other times by a spring or other suitable instrumentality. These means may of course be employed whether the power-driven mechanism effects the release of the scale, or the printing and delivering of the tickets, or other object.

The invention further comprises the combination of the improved printing mechanism with balancing mechanism in general, having a counterpoise of the kind before specified,and ticket-delivery mechanism generally (either or both) with or without power-driven operating mechanism and with or without the improved coincontrol, or a coin-control generally; also, the combination of the improved ticket'deliv- Lil ery mechanism with such balancing mechanism and printing mechanism generally with or without power-driven operating mechanism and wither withoutthe improved coin-control,or a coin-control generally, as well'as the combination of such improved printing mechanism with the improved ticket-delivery mechanism with or without balancing mechanism having a counterpoise of the kind specified, with or without power-operating mechanism and with or without the improved coin-control, or a coin;control generally; also, the combination of the improved balancing mechanism with the improved printing and ticket-delivery mechanism, or such mechanisms in, general with or without power-operating mechanism and with or without the improved coincontrol, or a coin-control generally.

The invention also comprises certain special constructions, combinations,and arrangements of parts, as hereinafter set forth.

The following is a description of what is considered the best mode of applying the principle of the invention, reference being had to the accompanying drawings, which form part of this specification.

"Figure I is a front elevation of a coin-controlled weighing and weightprinting machine constructed in accordance with the invention; Fig. II, a View in vertical section and rear ele vation on a larger scale, certain portions of the machine being omitted and certain parts broken away; Figs. III and IV, similar views in vertical section in planes at right angles to those of Figs. I and II in elevatiomlooking in opposite directions, respectively; Fig. V, a de tail view in vertical section of a portion of the printing and ticket-delivery mechanism; Fig. VI, a detail view in horizontal section of'such mechanism; Fig. VII, a detail view in perspective of a portion of the ticket delivery mechanism; Fig. VIII, a perspective view, partly in vertical section, of the upper part of the machine; and Fig. IX, a detailview, in vertical section, showing the eoinoperated escapement-lcver and the parts more immediately connected therewith. I

The lever A of an ordinary platform-scale is connected by the rod 13 (see Figs. I, II, and III) with the lower end of a steel band, B, which is wound on the axle Oofa drum, G, so that when the platform is depressed the band is drawn down and the drum G is turned. This drum G constitutes the rotatory device through which the pressure of the object weighed is conveyed to the counterpoise I, formed, as shown, of a chain of weights, as described in my aforesaid patent, the top weight of the chain being connected through the stirrup E with the steel band H, whose upper end is fastened to the drum G, so that as the drum G is turned by the pull on the band B the band H is wound on its periphery and the weights I lifted in succession until the weight on the scale-platform is balanced. The double bearing for this rotatory device is formed by the journals 1, which are upheld by stationary cross-pieces D. They rest upon the level bearing-surfaces 2 (see Figs. II and VIII) between the stops 8, but normally out of contact therewith.

Whenthe scale-platform is depressed and the drum G is turned, the journals 1' roll on the surfaces, thus forming a non-sliding bearing until they strike stops 3, whereupon they turn like ordinary journals or pivots, thus forming a second bearing whereof one .part turns in or on the other until the increasing force of the counterpoise I arrests the motion of the drum G. As this will'not take place until the parts have passed the point of balance, the force of the counter-poise will turn the drum in the opposite direction, thejournals rolling to the stops 3, at the other end of the surfaces 2, when they again turn or may turn as pivots. Finally, the vibration results, simply, in rolling the journals 1 on the surfaces 2, and the balance is secured with the journals 1 out of contactwith the stops 3, and, consequently, by means of a bearing without sliding friction.

In order to reduce the extent of the vibrations the fan F is placed in the stirrup E, so that the resistance of the air to the rapid rotation of the fan may moderate the motion of the stirrup and parts connected. The fan consists of wings 4, fastened to the shaft 5, whose ends are pivoted in the sides of the stirrup and which in the middle is provided with a pulley, 6, for revolving the fan by engagement with the cord 7. This cord is wrapped once around the pulley, its upper end is fastened by eyeplate 10 to the top Z of the machineframe, and its lower end is secured to the stationary post 8, whose base is fastened to a shelf, 9, in the baseZ of saidframe. \Vhen, therefore, the stirrup E is moved up or down, the pulley 6 travels along the cord and is rotated thereby. fit over the post 8, as in said patent. The bottom weight ofthe chain'is connected with the upper end of aspiral tension-spring, 1l,whose lower end 'is fastened to the post, so that if all the weights should be lifted the tension of the spring will prevent excessive motion and disarrangement.

The weights'I are placed in a stationary tube, 111, mainly to conceal the weights or counterpoise, except in operation, for the purpose of increasing the interest of the public in the machine. The said tube, however, also serves as a protection to the eonnterpoise. It may of course be omitted.

The printing form or band K,of soft rubber, consists (see Figs. V and VI) of the backing 12, the type 13 on the face thereof, the teeth 14 onthe back, opposite the spaces between the type,and the side flanges, 15. It is or may be provided with a re-enforce, 150, or strengthening-strip of cloth, as customary in bandsinside dating-stamps. It is adjusted by the drum G, on which is wound the steel band K,whosc The weights I are hollowand lower end is connected with the upper end of I I G is turned by the weight on the scale-platform,theprinting form or band K is lowered in front of the printing'finger 16, and the parts are so adjusted that when a balance is secured the characters or type 13,whic-h represent the weight on the scale, are opposite said finger.

The type are inked by the inking roller Q, and the printing form or band K is guided by the said roller in connection with the guideroller Q. These rollers each have flanges 17 and 170, respectively, which lie outside the flanges 15, and portions 18 (see Fig. VI) ofthe periphery of the roller Q form bearings for the back of the said flanges 15. The periphery of the roller Q, between the portions 18, is cut away for the passage of the teeth 14. The rollers Q Q are journaled in bearingpieccs 19 and 20, respectively, which are fastened to the card-box I.

The lower end of the printing form or band K is provided with a light weight, 21, (see Figs. II and V,) to keep it stretched, and said weight is connected through a spiral tensionspring, 22, with a flexible cord, 23, whose lower end is fastened at the bottom ofthe tube 24, which forms a guide for the weight 21. IVhen a person steps off the scale, the printing form or band K is lifted very rapidly. The spring 22 and cord 23 gradually arrest the motion thus imparted and prevent the weight 21 from being thrown out of the tube 21.

The card box P (see Figs. I, II, and III) is supported in an upright position by arms 25 from one of the corner-pieces Z, which are made of angle-iron and connect together the top Z and base Z of the machine frame. The front 26 of this box is hinged at 27, Figs. I and IV, so that it can be swung out for the introduction of the cards. The piece 28, Fig. V, in connection with the roller S, forms the bottom of the card-box. A curved dischargepassage, 29, formed between the periphery of the roller S and the concave 30, extends from the back of the card'box down in front of the printingfinger 16. The concave 30 is provided with an opening, 31, through which the type 13 may be pushed by the printing-finger 16, in order to make an impression on the card in the lower end of the discharge-passage 29.

The bottom card is pushed from the cardboxinto the discharge-passage 29 by the reciprocatory pusher R, whose thickness is that of a card. It has depending side flanges, 32, (see Fig. VIL) so that it will be impossible for a card to et under the pusher. The discharge-passage 29 eontai as several cards which are pushed through, each by the card behind, when the pusher advances, the roller S rotating with the card, so that there is but little friction.

The pusher It is fastened to arms 33, Fig. VI, on the front, and the printiugfinger 16 to arms 34 on the rear, of the printing-lever L, pivoted at 35 to the card-box P, and operated by a crank-pin, 36, Figs. II and IV, on the shaft 37. The crank-pin 36 works in a slot, 3S0,'in the lower end of the printinglever L.

.Vhen the lever L is moved forward, the printing-finger 16 enters between two of the teeth 14 and presses the type opposite into contact with the card, and on the return movement of the said lever L the pusher R forces a new card into the discharge passage 29 and forces out the printed card. The shaft 37 is geared by a fast pinion, 38, and fast spur-wheel 89 to the shaft tO, on which is a loose drum, 41, pro vided with a ratchet-wheel, 42, which is engaged by the pawl 43 on the spur-wheel 39, so that the drum 41 can be turned independently of the shaft 40 for winding.

The weight T, Fig. III, which furnishes the power for printing and delivering the cards or tickets, is suspended in loops of the wire 44, which has one end fastened at 4-5, Fig. III, to the cross-piece 450 in the top Z, runs around the pulleys 46, 47, 48, 49, 50, 51, 52, 53, and 54, and is wound upon the drum 41. The power-weight T is guided by ears 55, sliding on stationary rods 56. The descent of the weight tends to rotate the shafts 37 and 40 in the direction of the arrows.

The shaft 57 (see Figs. II, III, and IX) is geared to the shaft 37 by the fast pinion 58 and the fast spur-wheel 59, which are of such relative size that the shaft 57 makes four revolutions to one of the other, and the escape meat-lever \V, fulerumed on the rockshaft 60, has a tooth, 61., which engages a pin, 62, on the spurwheel 63 fast on the shaft 57, and prevents the rotation of the mechanism driven by the wcightT. \Vhen the escapemeut-lever W is moved back, the tooth 61 is removed from the path of thepin 62 and rotation of the mechanism is permitted. The escapement-lcver W is so weighted that it'tends to swing forward and place the tooth (it in the path of the revolving pin 62. The ends ofa cross-piece, 630, fastened to the lever \V, act asstops to limitthis forward motion by contact with the frame (it, by which the various parts of the mechanism driven by the weight T are supported. After the escapement-lever IV has been moved back it would, if left free, arrest the rotation of the mechanism as soon as the shaft 57 and pin 62 had completed one revolution. To prevent this, three pins, 65, are placed on the spur-wheel 59, and the escapement-leve1"N has an angular projeetion, 66, Figs. II and III, in the path of said pins, so that the escapement-lever W is moved back by the successive pins 65, and prevented from engaging the pin 62 until the shaft 37 has completed a revolution, and a ticket or card has been printed and delivered.

The fan U regulates the rotation of the powerdriven mechanism, it being driven by the spur wheel 63 through the pinion 67, Figs. II and III, and spur-whee1 68, Figs. II and IV, fast on the shaft 69 and the pinion 70 on the fanshaft 71.

The coin to release. the power-driven mechanism is directed against the lower end of the escapement-lever \V by the coin-spout X, Figs. I and III, and after acting on said lever \V the coil falls into the upper compartment IIfI I PO

of the coin-holder M. The spout Xis supported by a bracket, 72, fastened to theframe 645. At its lower end it is provided with narrow flanges 73, so as to support a proper eoin by the edges and allow small coin to drop through. An inclined strip, 74, fastened to or formed by a continuation of the front of the spout X, conducts any small coin into the coinholder below the escapement-lever W.

The coin-holder M is a compartment-wheel mounted on a horizontal axis in the frame 6* and driven from the shaft 40 through the gears 75, 76, and 77, Fig. IV. It makes a quarter turn forward at each revolution of the shaft 37, so that the coin, after releasing the powerdriven mechanism, is carried over to the front of the holder, where it remains exposed until the mechanism is again operated. The frame 64 and the mechanism. carried thereby are supported on top of the money-box 78, which is upheld by the shelf 9 of the base Z, and receives the coins as they are discharged by the coin-holder M.

As so far described the machine would operate to balance 'the'weight of a person who should step on a scale-platform without the introduction .of a coin, but would not deliver a ticket printed with the weight until a coin was introduced. To look the balancing mechanism until a coin is introduced, the lock or detent N (see Figs. II, IV, and VIII) is provided. Thisis mounted on a stud, 79, screwed into the bracket 80, and is acted upon by a spiral tension-spring, 81, to hold it in engagement. The spring 81 is connected at one end with a pin, 82, on the side of the lock or detent, and at the other end with the pin, 83, on the bracket 80. The pin 82 acts as a stop by contact with the top of the bracket. The lock or detent N engages a locking-plate, 84, on the side of the drum G, as shown in Figs. II and VIII. It is withdrawn by a pull on the cord or wire 85, which is connected with an operating lever arm, 86, on the lock or detent. The lower end of the cord or wire is connected with the lever 87, which is moved by the finger 88, rotating with the shaft 37, so as to pull on the cord 85 and unlock the scale. The tail oflevcr 87, by engaging the pin 871 on the frame 64, limits the forward motion of the said lever. When a person steps off the scale, the drum G flies back and thelockingplate 84 is engaged by detent or look N. To diminish the jar at such times, and also when the drum G is turned to the full extent, soft- rubber buffers 89 and 90 are provided on the lock or detent in the path of the locking-plate 84, and pieces of soft rubber, 91, are placed between the edges of said plate and the adjacent walls of its holder 92. The buffers 89 and 90 are formed in one piece with a connecting-strip, 93, and they are fastened to the lock or detent by a trough-shaped piece, 94, which embraces the rubber and aportion of the detent, and is fastened to the latter by screws. The holder 92 of the locking-plate 84 is fastened by its flanges to the drum G. A piece of rubber,

163, is also placed on top of the lever A to act as a buffer.

The standard of the machine is inclosed on all sides. The front is hinged, (see Fig. 1,) so as to open and give access to the works inside. Its upper part, 95, is made of glass, so as to expose the works to view, and a vertical partition, 96, Fig. III, in front of the weight T, is provided with a mirror, 97, to reflect the said works. There is a slot, 98, in the glass for the introduction of coins, and an opening, 99, for the delivery of theprinted cards, which slide down the incline 100, Figs. IV and V, onto the shelf 101 outside the machine. The sides 165 and 166 of the case, or a part thereof, are preferably also hinged and made of or provided with glass.

In order to close the coin-slot 98 when the power-driven mechanism is run down, the movable shutter J, Figs. I and II, is provided. It is arranged in proximity to the said slot 98,

and is mounted on the lever-arm 167 (see also Fig. III) of a rock-shaft, 168, journaled in bearings on the shelf 9, so that the motion of said rock-shaft in one direction or the other turns the shutter across the slot or withdraws it. A torsion-spring, 169, on the rod 168 normally holds the shutter to one side, as shown. A rod, 174, connected at its upper endvwith an operating-arm, 173, of the shaft 168, has its lower end arranged in the path of the power weight T, so as to be struck by the weight T when the latter is near the end of its fall, and the rock-shaft 168 is then turned to place the shutter across the slot and prevent the further introduction of coins until the weight is removed.

When a person desires to ascertain his weight by this machine, he steps upon the platform. Since the drum G is locked by the detent N no movement of the machinery takes place. A proper coin is then introduced into the machine through -the slot 98. It falls through the coin-spout X, is directed against the escapementlever W, releases the mechanism driven by the weight T, and falls into the coinholder M. The rotation of the said mechanism first causes the finger88 on the shaft 37 to move back the lever 87, and thus to pull on the cord 85, turn the detent N, and release the drum G, which immediately commences to revolve under the pressure conveyed from the scaleplatform through the lever A, rod 13, andband B, and to wind up the band H, lifting the counterpoise-weights out of the tube 111, and lowering the printing form or band Kin front of the printing-finger 16. After some vibration, as before explained, the balance is secured without friction. The parts are so adjusted that a reasonable timeis allowed for this to take place before the power-driven mechanism, which continues to revolve, has, by the action of the crank-pin 36 on the printing-lever L, brought up the printing-finger 16 into position to press against the printing form or band K. After such time, however, the print ing-finger 16 enters between two of the teeth 1 1 and pushes the type 13 opposite said finger, through the opening 31, against the card in the discharge-passage 29. This prints the weight from said type which have been inked by contact with the ink-roller Q. During the advance of the printing-finger 16 the pusher R has been removed from under the pile of cards in the box P, which cards drop down, bringing the bottom card in front of the pusher B. After thcprinting has been effected the crank-pin 36 moves back the printing-lever L, and the pusher R, acting against the edge of the bottom card or ticket, forces it ed gewise into the passage 29,1'otating the roller S and discharging the newly-printed card, which falls upon the incline 100 and slides out of the machine onto the shelf 101, to be received by the person weighing. The powerdriven mechanism, after one revolution of the shaft 37, is automatically arrested by the escapement-lever XV engaging the pin 62, and so remains until another coin is introduced. \Vhen the person steps off the scale,the weights I descend into their tube 111, the drum G is revolved until the locking-plate Si is engaged by the detent or look N, which holds it stationary until the said detent is disengaged by the power-driven mechanism on theintroduction of another proper coin. This reverse revolution of the drum G of course winds up the bands B and K, ready for a new operation. The coin remains exposed to view in the coin-holder M until the next operation of the machine, when it is discharged into the money-box 78.

Y In the foregoing particular description details are given for the purpose of enabling others to make and use the invention; but it will be understood that the invention is not limited to them.

The term coin motor, as employed herein, signifies a contrivanee of any suitable description whose condition or operation is effected by the introduction of a coin, such coin-motors being known in a variety of forms for various purposes.
