EBPECIPICATION arming part of Letters Patent No. 384-,659, dated June 19,1888.

Serial Nor 918,179. (No model.)

.40 (Ml 107 ,0125. it Be it known tl ject of the King of Sweden and Norway, residing at Liverpool, in the county of Lancaster, in the Kingdom ol'England, have invented certain new and useful improvements in \Veighing-hiaehines, of which the following is a specilication.

This invention relates to that class of machines for which I have already obtained Letters Patent of the United States No. 294,713, and is best described by aid of the accompanying drawings, which is made in two scales.

Figure 1 is a front elevation of my apparatus. Fig. 2 isa general plan on the same scale, with half of the platform and the cover over the lever-coupling removed, showing the machine box and lever. Figs. 3 and 4 are respectively a plan and ole 'ation of machine levers. l? is an enlarged cross-section of lever on the line 5, Fig. 3. Figs. 43 and T are sectional views. on an enlarged scale, on the lines 43 (i and T Ii, respectively, of Fig. 3; Fig. 8 an enlarged plan view, and Fig. 9 a sectional view, of the weighingmachiue itself on the line {i 5'? of Fig. Fig. lOis partlyatransverse section and partly an elevation on the line 10 ll of 2, showing indicating apparatus and relieving apparatu Fig. 11 is a sectional end elevation of indicating apparatus on the line ll. 11 of Fig. 2. Fig. 12 is a sectional end elevation of indicating apparatus on the line l2 12 of Fig. 2. Figs. 13, 14, 1.5, 16, and l? are respectively elevations and plan 01 the relieving apparatus on an enlarged scale.

in the drawings, A is the weighing table or platform, with beams B and B, the former of which are secured at .ach end to two crossbeams, l1, Eiig. 8, one at each side of platform A, having small shoes 0 at each end, and the whole resti 11.4 on the knife-edges c oi the levers C and (3, Figs. 2, 4, and 9. The limbs of the levers (I 5.) have the cross-section of the letter L, this form being thcbest to resist thcstrains they are required to withstand, and easy to mold, the 1 or lever O,consisting of the main limb I), bell in a diagonal direction, with strengthening-webs Z Z, and the minor limbs L edges forming fulcrums. In the pattern for casting the limb L is placed centrally between the knife-edges 0 c and rests on the bottom flange of limb L and joins limb L on the other side. Limb L rests also on bottom flange of limb L. L and L arejoined'by the diagonal stay-limbs L and L, and also by the central stay-limbJf. Thelimb L is at an angle to the limb L and held together by the said staylimbs L L, and L, and forms a strong beam, both to resist torsional as well as bending strains. The reason why one flange rests on the other, instead of running into the other, is that the pattern by this means is stronger and easier to make; otherwise allthellanges could be in the same plane, running into each other. The minor lever O is built up exactly in similar manner, and consists of the main limb L and the minor limbs L I, with the staylimbs L L" L', and the hanger-shaped ends G, pro vidcd with knife-edges c forming l'ulcrums. On limb L of major lever O is ashort arm, 0, that is cored out to make room for the couplingliuk C, Fig. 6, and on C is fitted a mull, C, provided within, on the bottom side, with a knife-edge, c, and this mutt G is just set in the desired position and secured by the setscrew 0 Figs. 3 and 7. In casting, the short arm 0" can be fixed on the pattern at any desired point on the limb L. If G is brought low down on the pattern nearer the hanger G, this will suit a shorter machine, and it C is fixed on the pattern higher up on the limb L,nearer the center of suspension 0, it will adapt itself to a longer machine. Again, if hanger G on limb L of major lever O and hanger G- Onlimb L of minor lever C are brougl'itihrther outto the side by an extensionpiece or brought farther in toward the center by a stopping-oil piece on the pattern, the levers G and G will then be adaptable for narrower or wider machines. The limb L of minor lever G can in the same manner be made shorter or longer by a stoppingoil' or an extension piece For the pattern to meet the position of C on limb L of major lever The limb Lol minor lever O is also made hollow or channeled at O to make room for the coupling-link (3*, Fig. 6, and a muff, C is fitted on and provided within on the top side with a knife-edge, c and set in the-desired position and secured by the set- ICO screw 0 The adjustment of the levers O and G at the couplings C and 0, Fig. 4, becomes very easy, as their position is on the outside of the platform A, and they can be got at through the hand hole 13*, Fig. 2, of the boxneck B without' disturbing any parts of the weighing machine. The position of'these coupling-centers e and 6, Figs. 4and 6, are of course equally distant from the fulcrum-0cm ters e of the levers O and O. The distance between the two coupling-centers e e", as shown in Figs. 6 and 7, is by this arrangement brought down to a minimum, which is very important in the coupling of a pair of levers to insure sensitive weighing. The form of these levers is of advantage on account of leaving the center space of the machine unoccupied and allowing the beams which carry the platform with the load to come down in between them, and also in larger machines they allow a free access down into the pit of the machine-foundations and the whole can begot into ashallow box.

The lever G is carried by its fulcrum knifeedges 6 in the links 6 Figs. 2, 8, and 9, hanging in the corner-box brackets B of the machine-box, and suspended in the shackle G, Figs. 10 and 16, by the knife-edge in muff 0, Figs. 10, 2, and 3, which is adjustable and secured by set-screws 0", Fig. 4, and hooked onto the suspension-rod G Figs. 10 and 16, in the relieving apparatus. The minor lever C, Fig. 3, is suspended by the knife-edge c, Fig. 6, in muft G from the coupling-link O", that is again carried by the knife-edge e 'in muff G on the short arm 0 on the diagonal arm L, Fig. 3, of major lever G. The link 0 Figs. 8 and 9, in one corner-bracket is connected bya rod, 6, to the link 6 in the opposite cornerbracket of the machine-box. of the links 6 by the rod 6 prevents the levers O and 0 from moving in a direction opposite to each other, but still allows a simultaneous parallel action to take place by any side motion of the platform A.

The platform A, Figs. 8 and 9, with beams B and B and cross-beams B at each end of machine, will rest at the points B of the four corner-brackets B when the machine is thrown out of gear, as shown in Fig. 8. The platform A is made of wood, and the central planks, 1?, Figs. 8 and 9, are secured to the wooden beams B and placed on the main wooden beams B. The two outside planks, P, are secured to the cross-beams B at the overhanging parts B", Fig. 8. The three sides B, Figs. 1 and 9, of the machine-box can also be made of wood and dovetailed into the corner-brackets B and plates B are let in on the outside and secured with bolts through the brackets B The neck B of machine-box is of metal and bolted to the corner-brackets B Figs. 11 and 12, and to the casing of the relieving apparatus at B. By this mode of making the box a great deal of metal is saved. The suspension-rod G Figs.

pensionknife edge 0, Figs. 3 and 4, in the muft'on the major levers limb L. The suspension-rod G has at its upper end two lateral projecting shoulders, r, and the shackle g. This latter is hooked up by the hook r, hanging by the bolt in the eye of shackle-guard g,

which in turn hangs on the shackle y", suspended from the knife-edge h on the arm k of the compound leverH of the indicating apparatus, Fig. 10, where all the transferred power from the levers O and O is taken up, by these means.

The indicating apparatus in Figs. 10, 11, and 12 is drawn in its half-way position. The indicating apparatus consists of the compound lever H, supported on the knife-edges 72. working on frame F, carrying a sliding weight, I, on the arm If, having a scale for adjusting said weight and a clamping-screw, 2'. This weight I is used for weighing oft the tare. On the said arm If, at the extreme end, is suspended from the knife-edge h the shackle g and suspension-rod g, with piston K in plunger J, filled with any suitable liquid and covered with the boxcover J.

The piston K is made up of a number of plates, 2;, a little apart from each other to allow the liquid to form a hydraulic packing. The cover Jhas a hole in its top and bottom large enough for the suspension rod g to pass through, plus clearance, and is made in the form of a box, that the fluid in the cover may act like a cushion for the fluid that tries to rush up through the bottom hole, and also for the purpose of hindering motion of the liquid in the plunger-box J by the working of the piston K. The other arm, h, on the opposite side of the knife-edges h has a counterbalance-weight, 1, by which the indicating apparatus is brought to zero, and is also provided with a knifeedge, h, fixed at the same From knife-edge h is suspended the shackle and suspension-rod g, with piston Kin plunger-box J Thislatter is filled with fluid (petroleum or other oil preferred) and covered with the box-cover J and is in every respectlike its fellow plunger box, J. Piston K in plunge-box J cheeks undue oscillation of the compound lever H in its upward movement, and the piston K in plunger-box J acts in a similar manner for the downward movement.

The arms h and h constitute the equal beam of the compound lever H.

To insure the same level of the fluid in the two plunger-boxes J and J they are provided with a tube, T, which is provided with acock, T, fixed on the side near to the bottom of the two plungers. Thus, when the fluid is poured into one plunger the cock T is opened, and the liquid will find its own level through the tube T. The communication is then closed, if desired, by turning the cock T.

When the plunger-boxes J and J are to be emptied, the cooks T and T, Figs. 10, 11, and 12, are opened and the fluid runs out. The liquid in the plunger boxes may be at a IIO high or low level without having any interfering effect upon the counterpoise-weight \V. The arm h, going in a downward direction, is at the extreme end provided with a knife-edge, h from which is suspended in the shackle the counterpoise-weight IV. This arm it constitutes the pendulous lover or pendulum. The arm 71?, going in an upward direction and bolted to and forming a part of the compound lever H, carries the dial D, on which are a series of scales, (1, for the minor weights, and a scale, 61/, on the edge of the dial for the major weights. The indication on the dial takes place in the following manner: On the arm h is bolted a segment-quadrant, M, on which is fastened by its one end a chain, M, that passes round ahelical grooved pulley, 0, working in a bracket, S, 'flXCd on the carrier-frame F, bolted on the base-frame F The chain M is fastened on the middle of the pulley O to prevent its slipping, and a weight, Q, at the other end keeps the chain tight. 0n the inner pivot of the pulley O is fixed a pointerwheel, 0, that points to the scales (1 for the minor weights on dial D, and a pointer, 0' that is fixed on the casing points to the scale (1 for the major weights on the edge of dial. D.

To bring the machine out and into gear, I make use of the relieving apparatus, as shown to a larger scale in Figs. 18, 14-, 15, 16, and 17. A hand-lever, It, Figs. 1, 2, 1.0, 11, 12, 13, 14:, and 15, is fixed on the one end of spindle It, working in the bearing R bolted on the frame F, and on the other end is fixed a radial grooved disk, The disk It works the disk 3*, provided with three pins with frictionrollers 9', equally distant from each other, working in the grooves r of disk B. The disk It is fixed on the end of spindle G working in the bearings G", bolted down on the frame F, and has also fixed on the same spindle, in between the bearings G",apinion, G working into rack G, guided in the guides G which are in one with the bearings G. In one with the rack G is a bracket, G for the purpose of taking the suspension rod Gr at the forked part r of the same. If the hand-lever It be lifted np-say as much as an angle of forty degrees the grooved disk It", turning disk R" by the pins with frictionrollers r to double the amount-that is, to eighty degreesand having the pinion G on the same spindle, G, it lifts the rack G, with bracket G till it lifts out the shackle g at the fork part rof the sus pension-rod G (that carries the levers, 850.,

in the weighing-niachine) from the hook 1",

and, as the shackle g is made with a curvature to the one side at the upper part, it is heavier on that side, and will therefore fall back onto the gi'iard-shackle g. The hook 2", that is balanced by the hall a will fall a little to the side,

shown in Fig. 16. As the shackle g is unliooked from r, the compound lever H, Fig. 1.0, will then be resting by its arm h in the carrier frame F atf. By reversing the action of the hand-lever It, Figs. 13 to 17, the rack G", with the suspension-rod G resting in the bracket G will then be brought down, and the shackle 9 will be guided forward and down on guard g, as shown dotted in Fig. 16, but cannot fall forward more than the projecting parts 0" on the shackle 9 will allow, as these will rest on the fork partrof the rod G The rod '9 with the levers will be brought down till the beams 3* in the weighing-machine come down upon the parts B oft/he bracket 13.

To putthe apparatus into gear, I repeat the operation and lift the hand-lever R on spindle It, carrying the grooved disk *1, that rotates the disk vt on the spindle G, and with it the pinion G". This latter works the rack G, thus raising or lifting the same with the suspension rod G in the bracket G till the shackle 1 comes up against the hook r. This being nicely balanced by the ball 1- will be easily pushed upward and aside till the shackle g has passed the book 1''. Then the book 1* will fall back again, aml thus cause the shackle g to catch the hook r, The hand-lever R, that works the rack G", is now again brought down to its original position, as represented in Figs. 1.3 and 10. I

The machineis now connected with the indicating apparatus, the cart is brought onto the platform A, and its weight found by moving the tare-weight I, Fig. 10, on the arm 71.". When the tare is ascertained, the weight I is fixed in its position by the setscrew i. The cart now returns loaded onto the platform A, and causes the compound lever II to move slowly. The dial 1) on arm 7L3 consequently passes from right to left, and at the same time the pointer-wheel O to rns round, being worked by the chain Iii round the helical grooved pulley O. The major weight is now read off on the scale d at the pointer 0 and the minor weight on the scales (Z by means of the pointcrs of the pointerwvhccl O.
