SPECIFICATION forming part of Letters Patent No..294,'713, dated March 4, 1884.

Application filed August 13, (No model.)

Patented in England February 512, 1883, No. 077, and in Belgium September 17, 1883, N:G2,615.

[o all wlw/n t may con/cern:

Be it known that I, EUGii-N VLNER, a

y subject of the King of Norway, residing at Liverpool, in the county of Lancaster, inthe Kingdom'of England, have invented certain new and useful Improvements in Veighing- Machines, (for which I have received Letters Patent in England, dated` February 22, 1888, No. 977, and in Belgium, dated September 17, 1883, No. 62,615, and for which I made application for Letters Patent in Germany on or about the 14th day of September, 1883, and which have not yet issued,) of which the following is a specification.

My invention relates to a weighing-machine in which a pendulous lever provided with an indicator to move over a dial is raised by the weight applied to the platform, the pendulous lever being furnished with a cylinder which moves relatively to a xed piston fitting loosely within the cylinder, whereby undue oscillation of the lever and indicator is prevented.

This invention is set forth in the accompanying drawings.

Figure 1 is a'front elevation and part section of my apparatus; Figs. 2 and 2, a sectional side elevation Fig. 8, a transverse section on the line a' a0 of Fig. f1, showing indicating apparatus; Fig. et, a part plan of apparatus; Fig. 5, an enlarged sectional plan on line y y of Fig. 1. Figs. G, 7, 8, and 9 are respectively an elevation, plan, and part side elevations of diagonal arm. Figs. 10, 11, and 12 are respectively a plan, front, and end elevations of beam withdiagonal arm in position; Fig. 13, a transverse section of beam, Figs. 14, 15, 16, enlarged sections of stool.

In the drawings, A is the weighing table or platform. This rests on the stool B, which is provided with four pairs of legs, B', one pair at or near each corner resting on the round shafts c. These shafts ride on the stirrup-links e. These stirrup-links are hooked onto the saddle-links e, which in turn are mounted on the knife-edges e2 of the load-arms C5 of the leverbeams G" G. The said stirrup-links e and saddle-links e, being hook-shaped, can be Aunhooked or dismounted without disturbing or removing the knife-edges e2.

'C'l C" are lever-beams of cruciform section,

this form being the best to resist the strains it is required to withstand, and the easiest to mold. These lever-beams are supported at their hanger-shaped or elbow-shaped ends G, and are provided with knife-edges forming fulcrums. elbowshaped,and the center of gravity of thc cross-section being in the line of the fulcraedges at G, the motion will he a swinging or .rocking one in stable equilibrium-a great advantage, only gained by this arrangement. The load-arms C", with their knife-edges, are on the inner side of the fulcra knife-edges at G, thereby dividing the load on the fulcra-supports, and thereby also entirely preventing any tipping action of the lever-beams. The power is transferred from one lever-beam to another or equalized between them by means of the bar E, preferably adjustable as regards length by right and left handed screws and nut E. This is supported at each end on knifeedges F F on the arms C C', one of said arms being on the under side of beam G2, and the other on the upper side of beam C. There can be more than one of these bars and corresponding knife-edges and arms, if required. The major lever-beam C is provided with a circular rim, C, as shownv in Figs. 10, 11, 12, and 13, and the lever-arm CL with a correspondingly-cnrved flange to fit said rim. The rim is provided with a row or two rows of slot'- holes extending horizontally all round the rim, and the lever C" can be fixed to any point of the segment of the circle by bolts passing through said slot-holes and tlange. Its upper and lower halves on opposite sides of the center line are similar. In consequence of this arrangement, one pattern of an arm, O, can bev used for a great variety of machines, and being made reversible'it will do for righthanded or 'left-handed machines. In adjusting, the arm is slid round the rim till under the point of suspension, or till the knife-edge at the point of suspension is square with the other series of knife-edges in the machine.' It is then bolted. For the still further adjustability of the maj or lever 0*, it is provided with a loose :nuff fitted over its extreme end, and capable of being moved along the end of the said lever-arin, its position being regulated by The ends of these beams being adjustingscrew CT. The mult' C"g is provided vwith a round rim, C, having slotholes in a horizontal line for the fastening-bolts C1", used for securing ythe 'short piece C, in which is bedded the suspension knife-edge for the leverarm C. This short piece is provided with a circular flange to suit the .rim of the muli, and is fastened by bolts thereto. By this arrange` ment the position in relation to the length or breadth oi" the weighing-machine can be regulated, `so as to get the correct weighing-length for the lever, andthe knife-edge at the point of suspension can yet be adjusted square with the other knife-edges. The lever G transfers the power to the suspension-rod G', which is hooked onto the shackles f/ y', hung from the knife-edge l1. on the arm h" of the compound lever II ol" the indicating apparatus. This arm can be one and the same with arm 71?, if desired.

The indicating apparatus shown in Figs. 3 and et consists ot'bell-cranklever II, carrying a sliding weight, I, on the arm h, having a scale for adjusting said weight. This weight is used for weighing ott' the tare, and also on the said arm h, at the extreme end, is the eounterbalanee-weight I, by which the indicating apparatus is brought to zero. Another arm of same bell-crank lever' II (marked ha) hangs down at a steep angle into a eistern, J, of liquid, and is provided with a counterpoise consisting of a heavy a-nd nearly-closed tube, Ii, working over a fixed piston, L, of rather less area than the tube, and leaving very little passage-way :for the lirqd, which thus acts as a iluid cushion against too rapid movement of the tube, and Lthus prevents sudden jerks or oscillations.

Instead ol' the cylinder being movable and 4o the piston iixed, the reverse could be the case; but I prefer the arrangement described. Pret'- erably I forni the pendulous tube in the i'orin ot' a curved cylinder tube or box, K, with a curved piston-rod, L, passing through it, and itted with a very loose iitting piston, L', working in thepsaid box or cylinder. The liquid in this ease acts as a cushion,enteringwatuthe ori- Iices roundthe,piston-rod, and also passing round the pis on in the cylinder, the small pas sage-ways allowing the cylinders only to in ove slowly, thus checkingviolent oscillations. On the axis of the bent lever II, I iix the lever 71 from the knife-edge 71., on which the shackles or rings g g', connectingit with the lever system, are suspended. The rod (fr', connecting the indicating apparatus with the system ol' levers, is preferably hooked onto a shackle, y, suspended from a ring, g', or its equivalent, on the knife-edge rlz.. Thehooked suspension-rodA Cr has a second hook, r, Figs. 3 and 5, the one taking into the shackle or its equivalent. 3elow this second hook is a crank, It, and shalt It', worked by a hand-wheel, It. The shaft .is locked in. either position by pin-catch It. If the hand-wheel be turned,the crank is raised and lifts the suspension-r0d G with the mechanism by the lower hook till the ilrst hook is lifted out of the shackle, and thus all connection between the indicating apparatus and the platform is cut oii; but theplati'ormis allowed to rest on.its frame-work, instead ol" on the knife-edges ci.

To put the apparatus in gear, a single turn of the handavheel carries the crank round, apd the latter' carries the lower hook, litts it, and guides it until it leaves the first or upper hook inits shackle, and ready again l'or work. A stop-catch or locking device ot' any ordinary construction is used to lock the shaft R3 in place when not requiring movement.

Retu rning,now,to the indicating apparatus, on arm h, which can be a mere extension oi' the tare-arm beyond the fulcrum, I lix a chain, M. This passes round the axis ol' pointer-wheel O, which axis is provided with a chain-wheel, teeth, or projections to interlock with the chain and prevent it slipping. A weight, Q, keeps the chain tight. 0n the end of arm h is a scale or dial with degrees, showing the major weights, and on the rigid frame a hand or pointer indicating the weight as the scale oscillates past it. On the same dial are a series ol' scales, 71.5, so arranged that the minor weights are read oft' by the fingers of the inger-wheel O pointing to them, the position of these minor scales being so arranged that the combined motion ol the ends ot' the pointers of the wheel and that ol the dial shall, always keep a scale exactly opposite the point o1" the pointer-whecl, and as one pointer leaves the end of one scale the other pointer arrives at the beginning oi' the next scale.

The mode ol" action is as follows: 'We will suppose the machine disconnected and at rest, anda cart ot' unknown weight arriving tohave its tare taken, preparatory to loading. The attendant unlocks the shalt At and turns it round, the crank .It rises and engages in hook rand raises it, turning round with it till it brings the upper hook over the shackle lf/,and, continuing the revolution, descends, leaving hook i' in shackle y; still further descending, it leaves hook r. The machine is now connected, the cart is backed on, and its weight found by moving the tare-weight I on the arm 7L. The tare-weight is then clamped in this position. The cart now returns loaded, and, arriving on the platform, causes the indicator bell-crank lever II to move. Arm lt rises, the major weights are read oit' at h", and the minoren the smaller scales by means ol' pointers of pointer-wheel O.

I am aware that grainscales have been provided with a cylinder having valved inlets and outlets to be actuated or controlled bythe tipping beam and a closely itting piston within said cylinder, the whole forming a brake to retain the beam in a lowered position while all the contents ol" its bucket are being removed. This I do not claim or use. My

construction includes no valves, but merely a cylinder and a loose-iitting piston, which together act in much the same manner as a lOO ITO

' adapted to be set at any required angle dash-pot in other machinery, and serve to prevent violent oscillations of the indicator, which would otherwise occur.

I am further aware that in a dynamometera pivoted beam has been furnished with a dashpot at one end, and connected at the opposite end with a gravitating indicatorarm by a chain; but in that case the dash-pot hadiio immediate connection with the indicator, but separate and special means independent of said dash-pot were furnished to prevent sudden or violent oscillations of the indicator.
