Io @cito/'m it' concern:
ne known that I, TWILLIS Il. JORDAN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of lifassachusetts, have invented certain new and useful Improvements in Coin-Controlled Benni-Scales, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to an automatic .veighing-niachine of that class in which there is a series of weighing beanis united by linlrs and coniing into play successively when a load is weighed. Thus the first or lower beani indicates weights ranging frein fifty pounds to two hundred or niore pounds in units of fifty pounds, wiiile the second or upper beani indicates weights ranging froni one to fifty pounds in units of one pound. It will be evident that both the beanis niust coperate to indicate a weight above fifty pounds the nunierical expression of which docs not contain two zeros or a live and a zero. liachines of this kind are arranged sliding-weight machines, a weight heilig slid or rolled on each beain by ineans, coniir nly of a rack and pinion and a verticallyvable rack until the beani is counterpoised, but in niy preferred forni by a spring-buffeted rack for the lower poise and by a spring-bud'er for the upper weight.
The principal object of iny invention is to provide beam-scale (which niay be of that type locked by a pawl, which pawl niay be freed by the insertion of a coin into a chute, which acts upon a lever and frees the nieohanisni allowingthe saine to be put in operation) 'having two or iiiore beanis cach provided with a weight-poise adapted to automatically )ass along itsrespective benin, niay be necessary to indicate the enact weight applied to the scale platforni, as soon as the niachinc has been set in nio-v tion by the niovenient of a handle or other equivalent nieans.
it is coninion in coin-controlled beani :les to automatically operate the balanceweiglit on the beain by drawing this weight outward on the scale-arni starting at zero and going upward toward the liioiier nunibers so that the arni begins to descend toward 'the level in the ordinary nianner of bea -scales, and passing along until the beani balanced and the weig it carried by the platforni accurately indicated by the balance-weight on the scale-arm as explained in niy United States Letters Patent nunibered @3,226 issued February 13th, 1900, but iii this particular invention I have reversed the process and start the poise on the lower graduated beani and the rolling weight used in indicating on the upper grady uated beanis freni the highest nuinb ers, allowing the saine, after the lower beani has been partly raised by the operation of a handle, to pass downward along the beain toward the Zero niarlis until the bcani is balanced, when as in the preferred foni the poise upon the lower beani would indicate the weight applied to the scale platforni, or the downward pressure upon the saine, in units of fty pounds, while the rolling-weight would indicate upon the upper graduated bcani the additional weight over said indication on the lower beani. For exaniple, if the poise on the lower beani has stopped at l5() pounds and the rolling-weight at 35 pounds, the weight or force applied to the scale platform would be 185 pounds, or if as shown in Figure l of the drawings, tiie poise stops at 100 pounds and the rollingweight at 4 pounds, the weight applied to the platforni would be 10i pounds.
In the drawings is shown a weighing-niacliine constructed according to this invention with two graduated beanie; but this invent-ion is equally applicable with any nuniber of beanis.
The invention consists in the combination of elements and in certain parts of novel construction entailed in the conibination of said elenients to obtain the desired result.
A full understanding of niy invention can best be Oiven by a detailed description of a preferred construction embodying the various features of niy invention, and such a description will now be given in connection with the accompanying drawings, and I obtain niy object by the niechanisin there illustrated, showing such preferred construction, and the features forniing the invention will then be specifically pointed out in the clainis.
Tn the drawings, Fig. l is a front elevation of the upper portion of niy iniproved beam-scale, the case being brel-:en away. Fig. 2 is a transverse sectional view of the saine looking toward the right. F ig. El is an enlarged sectional view of the poise and a portion of the lower beani. Fig. 4- is a sectional view on the line 1 /l of Fig. 3. Fig. 5 is a rear view of the coin-controlled pawl and contiguous parts. Figs. G and 7 are fragmentary views of the coin-chute and tripping lever. Fig. 8 is a view in front elevation ot' a portion of a modied t'orm ot' the machine. Fig. 9 is a transverse sectional view of the same looking toward the left. Fig. 10 is a View in front elevation of por tion of another modiiied form of the inachine. Fig. 11 is a plan view of a part of the mechanism shown in F ig. 10. Fig. 12 is a` detail view of part of the mechanism shown in Fig. 10.
Latitude is allowed herein as to details, as
they may be changed or varied at will without departing from the spirit of my iiiveir tion and the same yet. remain intact and be protected.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Tn the drawings, 13 represents the standard connecting with a platform resting upon the ordinary compound levers usual in scales of this class and to which the stee yard-rod or scale-rod 14 is connected in the ordinary manner. This construction being so well understood, it is not deemed essential to herein specifically illustrate or describe it. The scale-rod 14: has a loop 15, which catches in a loop 16, provided with eyes 17 and through which extend oppositely-eXtending lateral pivots or knife-edge bearings 1S projecting from the lever-beam 19 whereby the weight of the load is transmitted from the platform to the scale-beam. This scale-beam is of peculiar construction and constitutes one of the important features of the invent-ion. itis here shown it comprises two scale-beam bars 20 and 3S.
rigidly connected together at one end by aV heel or counter-balancing portion 32, and at the other end by an upright portion i0.
From the under side of the frame-plate 22, and near one end thereof, extends the suspension eyebolt or link Q3 to the lower end of which eyebolt is attached a clevisshaped supporting link 24; which extends downwardly on both sides of the lever-beam 19 and around the knife-bearings at this end of the lever-beam having its enge suspended downwardly, so as to be carried by the suspensiondink 2d. At its opposite end said lever-beam is provided with dowl wardlyextending knife-bearings 2G extending through the clevis-sliaped links 27 carried by the link or hook 2S which extends through the loop 29, provided with eyes 30 for receiving the oppositely-extending lateral pivots 31 projectingA from the heel or counter-balancing port-ion 32 of the scalebeam.
Extending upward from the top t'ramel the beam.
L2 is vertical standard 33 and upon ie scale-beam is pivotally supported ending lateral pivots 3l. o ncing por on 32 of the Ve-,ieani is curved lJ-shaped as at and it," upper part extending above the standand cariz-es directly above the pivots has ard a carrying-yoke Sli which supports one end or the bar and also one end or' a locking-bai' 21, the latter being provided with a the adjustable screw I, 3 3 extends.
iean bar 9.0 and the locking-bar 21 which is located above the upper scale-beani bar are both grat usted, the bar 520 in units preferably or ipirty pounds each wid the bar l units preY olv, et one pound. 'llie scale-beam bar 58 is placed i iove the scale-beam bar 20 and separated 5() on said bai' .9 and which is placed b ine locking-bar 21 is separne bar i the bar 21 so that when is balanced at the correct weight the bar 21 would rest and this rollingninnrolling-vvcight being swung dito v beneat e the exact i noeing l1 which rc u spring buffer 4B; this buffer giving motion to the scale-bean and l'initing downward movement. Yrlpon the top t Vi-pl also provided another im and downward a toothed rack l5 and tor other hereinalter described. This rack #l1-5 is in t e ear ot' the bar 20 being pivoted the stud le extending rearward from 1 d bai' 20 near the pivot 3l, and is provided with a downwardlyv rrojectiiig tooth tor its ot tit t ie iiiifv pounds, t teeth being nreterably spaced tar apart to allow considerable movement of the poise for every titty pounds. A pin et? extending' t' rn the scalebcain in the portion e() limits the upward movement oiFA the rack except when the rack limited in its upward move by the adjustable nuts -lS on the bar 49 extending' upward from the top 'trameilate 2Q.
`Upon the scale-bean'i bar 20 is a poise 50, which is provided with an opening 51, as is common in poises, and in which journaled the wheels or roller on the axles which rollers revolve upon the upper side ot' the bar 20, which extends through the opening 51 i allowing' the poise to run or pass freely along The opening 51 is wider at its lower portion to also allow the toothed rack t5 to pass through it and its portion below the rack is inclined as at 55 at the same angle as the long` side of the teeth 5l. rlhe height of the rack frt n the lower portion of one of the teeth to the top is equal or nearly so to the height of the portion of the bar Q0 which extends through the poise.
All of the mechanism of my invention7 with the exception of the lever 56, its handle o? and the pin 58 wnich it operates, is within a casing; the upper front portion being` preferably of glass 60.
The lever is prevented from downward movement by `he ratchet (3l on its shaft held by a key 'T but llowed slight movement by the enlargement of the keyway it, a tooth G23 of which ratchet is held by the pawl Get pivoted on the stud Go and controlled by a wire 6G having a foot piece extending` through an opening` 6T of the long and narrow coin-chute G8 so that when a coin is placed within .the chute it drops downward striking the foot-piece and pressing` the foot-piece and wire GG partly downward and raising the pawl (it so that the lever .5G can be moved downward by the handle 57. ln order to prevent the coin from passing the foot-piece of the wire GG in t-he coin-chute GS until after the operator has had an opportunity to operate the handle 5T, l provide a lever 69, having its weighted end normally resting upon the linger T2 extending,I outward from the ratchet Gl, a. pin 7l, limiting the up ard movement of the linger, and the other end of the lever being normally slightly above the pawl so that when the pawl has been raised by the weight of the coin it strikes against the lever 69 and remains there until the handle has been pulled down. lllhen the handle has been pulled down the lingger T2 moves downward, the weighted end of the lever G9 drops allowing the pawl to rise by the weight of the coin, so that the coin passes the foot-piece of the wire SC; the pawl thus freed of the wein-ht of the coin then drops back in place ready to catch and hold the ratchet and the handle 57 when they returned to their initial positions by the c ntraction of the spiral spring T5 on the lever 7G from which the pin 5S extends, protrucinp,` through a runway 77 in the glass GO of l"he casing and niet by the under side of the lever rl"he lever '75 is fast on the shaft TS which carries a lever Tt) operatingl a lever 80 fast on the shaft Sl wnich carries lever 82 provided with a pin S3 acting` against the side of the head of buffer ist for preventing.;` too far movement. The levers 76 and T9 are returned to their initial positions by the spring 'T5 and a spiral spring 8l is providerV for returning the levers 8O and S2.
' Normally the scale-beam declines towart its outer end, so that the. poise 50 and the poise 89, respectively7 occupy positions at the outer end thereof and neither will start to move along toward the inner end the eof until the outer end of the beam has been raised high enough to decline the bars toward their inner ends. Furthermore, the bar 3S occupies a posit-ion out of parallelism with the bar 20, its outer end being` disposed nearer the bar than its inner end, so that as the outer end of tl raised the bar Qt) will first be caused to decline toward its inner end and afterward the bar The lever 82 when drawn upward by a movement of the handle i? strikes against the under side of the beam a id lifts the outer end thereof a short distance, far enough to decline the bar 2O slightly toward its inner end, so that the poise 50 can slide alongl thereon by gravity toward the inner end, and such movement of the beam is assisted by. the spring buffer t3, and the weight of the load being on the platform the outer end of the beam is further lifted by said load, is the scale-beam is lifted by the lever 82, it disengages the buffer el and the weight of the beam thereon having been removed, said buffer rises and lifts the rackbar fl-3 unt-il it strikes against the stop e8. t its movement the rack-bar which was normally in parallelism with the bar 2O before the lever 82 vas operated again in parallelism with it7 so that its teeth do not project below the lower edge of the bar. as the beam continues to rise by the action of the load upon the platform, assisted by the spring` buffer and the poise 50 continues to slide along,` thereon toward its inner end, said bar is gradually raised out of parallelism with the rack-bar and the teeth of the latter gradually project below the lower edge of the bar until one of the teeth thereof catches the poise and hecks its movement. ln the example shown in il l the weight on the platform being`- lOl: pounds the poise continues to slide along` on the bar 20 until it is checked by one of the teeth of the rack-bar at the point marked 100. rllhe poise does not st p at the point on the bar which would indicate lO-l no provision is mane for stopping it at such point.
rlhe lever 82 which is employed to lift the scale-beam is held in elevated position by a pawl S5 pivoted on the rear side of the bean and said lever prevents return in vement o the beam until such time as the beam ha, been raised high enough for the poise t slide alone` thereon and indicate the .veight, but as soon as it has been raised high enough to accomplish this result the pawl S5 will occupy a position above the upper enl of the lever and said lever is thereby permitted to return to its normal position, being moved by a springv Sel which is connected therewith.
It has been found very easy to build an rne scale-beam is yball 39 running in a groove' or sluiceway in the bar 38, which 1s suspended at one end m the carrying-yoke 36 and at its other end by 'the portion a0 of the scale-beam. The locking-bar 21 is also suspended at one end in the rcarrying-yoke 30, as at 89, above .the bar 38 and .ball 39 and its free end being limited y by the guide 86 and resting upon the adjustable nut 87 on the screw 4t2 protruding from the arm 88 extending upward from .the top frame-plate 22, and which arm 88 also supports the spring buffer 43 which causes the ball 39 to pass along the' sluiceway of the bar 38 until the `scale-beam shall have reached a point of balance when the bar 21 strikes upon the .top of the ball 39 and holds it from further movement, the scale-rod 14 having been drawn down by the weight of the load. 1t has been found desirable to .use a bar in the `shape of a slotted tube, the slot- `running lengthwise of the tube and sufficiently large to allow a small portion of the top of the ball 39 to protrude but not large enough to `allow the ball to fall or fly out. lllhen the poise 50 stops at the 100-pound mark on the bar 2O as previously explained, the scale-beam is not balanced, by reason of the weight of the loadexceeding the number of pounds indicated. The beam, therefore', continues to rrise and the bar 38 is moved so as to decline it toward its inner end and the rolling weight thereon is started, and rolls along toward the inner end thereof. The beam continues to rise by the weight of the load, assisted by the spring buffer 43, and the bar 38 gradually approaches the lockingar 21 until the' beam reaches the point of balance, when the rolling weight will engage said bar 21 and become locked thereby. 'li/Then the weightl is removed from the scale platforinboth the rolling weight 39 and the poise 50 return at once to their initial positions at the right end portion of the machine, and the other portions of the mechanism which have not already been returned, at the same time return to their starting point.
n the machine here shown the poises 50 and 39 are moved by the scale-beam toward the locking- bars 45 and 21 and into engagement therewith, yet if the scale beam should teeter, as it is liable todo, or if it should be raised too quickly and thereby cause' its poises to engage the locking-bars'before arriving at the point of balance of the beam, said poises may be disengaged from the locking-bars by a downward movement of the beam and in such case may be rapidly moved by the scale-beam into engagement with the locking-bars until finally the scale-beam balances and the' poises become locked at the point of balance.
ln the modification, shown in Figs. 8 and 9, the mechanism all similar to that shown in Fig. 1, except that do not pivot the left end of the locking-bar 21 in the carrying-yoke 36 but guide this bar in the arms of the yoke allowing' free up and down movement, resting this free end of the bar 21 upon the upper roller 91 of a bell crank lever 92 pivote'd at 93 in the bracket 9st; the lever 92 being limited in its movement by the pin 95 striking the under side ofthe bar 20.
ln the modiiied view shown in Figs. 10 to 12, the mechanism is also similar to that shown in F ig. 1 with the exception that lf do not pivot the left end of the locking-bar in a carrying-yoke but- I have the bar 21 at the right end rest upon an adjustable screwnut 87 of the arm 88 and the screw of the nut -98 upon which the other end of the beam 21 rests is inserted in a similar arm attached :to the top frame-plate 22.A instead of the scale-beam bar 38 being made as a trough l provide a pair of parallel runways 96 and 99 having the elongated slots 100 and 101 in which Yrun respectively the wheels 103 and 10-1 of the roll'ng-weight 102. rThe two runways 96 and 99 may be joined together ateach end and are attached to the two ends 32 and i0 of the beam. Between the runways 96 and 99 is inserted a toothed rack 106, which rack is fastened in any convenient manner between the two racks 96 and 99, and upon `the shaft of the rolling-weight 102 is carried a pawl 105 adapted to mesh in the rack 10G. A lever 112 is also carried by this shaft and is provided with a pointer 108 to point to the number of pounds to be indicated upon the bar 21; a slot 109 in the lever 112 is adapted to receive a pin 107 of the lever 105. After the poise 50 has come to a standstill upon the bar 20 the buffer 43 has a slight upward force which causes the roller 102 to be set in motion, by the pawl .105 being lifted by the pin 107 acting against the lower end of the slot 109 in the lever 112.
