GRAIIN-WEIGHINVG SCALE.

SPECIFICATION forming part of Letters Patent No. 393,888, dated December 4, 1888. Application filed April 23, 1888. Serial No. 271,595. (No model.)

To all whom it may concern:

Be itknowu that-I, HENRY CUTLER, of North \\-'ilhraham, in the county of Hampden and State of Massachusetts, have invented a new and Improved Automatic Graineighing Scale, of which the following is a full, clear, and exact description.

The invention relates to weighing-scales such as are shown. and described in Patent No. 375,267, granted to me December 20,1887.

The object of the invention is to provide a new and improved scale for weighing grain which is simple and durable in construction, not liable to get out of order, and is automatic in operation, delivering the weighed grain to the bags.

The invention consists of certain parts and details and combinations of the same, as willbe fully described hereinafter, and then pointed out in the claims Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 isa side'elevation of the improvement with parts in section. Fig. 2 is an enlarged perspective view of the lower part of the bag-support. Fig. 3 is an enlarged side elevation of one of the scale-beams. Fig. 4 is a plan view of the same. Fig. 5 is an enlarged perspective view of the knife-bearing, and Fig. 6 is a sectional side elevation of the improvement on the line on at of Fig. 1.

I The improved weighingscale A is provided with a base, B, in the middle of which is erected a standard, B, carrying a bracket, B extending equally on both sides of the standard B and carrying in its middle a bearing, 0, on which is mounted to turn an oscillating lever, D, carrying at its upper end a cylinder, E, extending equally on both sides of the said oscillating lever D. The ends of the cylinder E are adapted to rest alternately on the stops F and F, secured on the bracket B and in the said cylinder travels a ball similar .to the one described in the patent above referred to.

The ends of the cylinder E are also adapted to strike alternately against the arms G and G, pivoted at their lower ends to the bracket B and at their other ends pivotall y connected to the horizontal bar H, mounted to slide in suitable bearings formed on the front of the standard B"? The arms G and G may be rigidly secured to the bar H in order to move the latter when struck by the respective end of the cylinder E. The bar ll is provided in its middle with the lugs l-I.,between which is held a pin, I, secured to the oscillating hopper I, fulcrumed at I to the upper end of the standard B. The pin 1 passes through the segmental slot I formed in the front of the standard B. The hopper I is provided with a transverse partition, I", thus forming two compartments adapted to connect, respectively, with the upper ends of the chutes J and J, extending downward in opposite directions and opening into the cone-shaped hoppers K and K, secured by suitable flanges to the longitudinal beam B secured to the standard B and supported at its ends by posts 13'', resting on the base B. A deliverychute, I, is held above the upper end of the hopper I and discharges alternately into the two compartments of the hopper I, according to the position of the latter, and the respective compartment connects with its chute J or J, so that all clogging is prevented.

The hoppers K and K open into the cylinders L and L, respectively, each provided on its outside with pins L on which the mouths of the bags are secured, the bags fitting around the cylinders L or L, respectively. The cylinders L and L are supported on the frames N and N, respectively, connected at their upper ends by links 0 and 0, respectively, with the scale-beams P and P, respectively, fulcruined on the links Q and Q, respectively, pivoted at the outer ends of the bracket B The scale-beams P and P are also connected by the links R and-R with the slotted links R and R respectively, pivotally connected with the poises S and S, respectively, adapted to rest in their lowermost positions on the bracket Bflsecured to the standard B.

The links R and R are slotted, so that the links R and R move freely in the same until the scale-beam P or P, respectively, is in nearly a horizontal position, after which the links Rand R lift the links R and R" and the poises S and S, respectively, as hereinafter more fully described.

The scale-beams I and P are also connected with the oscillating lever D by links T and T, the levers D and D and the arms D and I) in the same manner as described in the patent above referred to. The links T and T take the place of the S-shaped hooks. On IO the lever D is pivoted a pointer, U, which extends upward and passes through a slot in the guide-arm E, secured to the cylinder E. In the slot of the guide-arm E are held adjust ably the set-screws E and E so that the i5 movement of the pointer l in the said slot-of the guide-arm E can be increased or diminished. This pointer serves as a balancingpoise, and it is allowed by the screws E and E to go out farther from the center in order to increase or diminish the load tobe weighed. The bearing-points of the scale-beams P and P are made in the following manner, and

as fully illustrated in Figs. 3, 4, and 5: Each scale-beam P or P. is' provided at its ends with the slot-ted heads P and P of which the head P is provided with two bea-ring-point-s one on its under side and one on t0pto accommodate the links Q and O or Q and O,-

respectively, and on the other head, P are 0 formed two bearing-points on its top edge to accommodate the links R T or R T. bearin g-poin t is made by two pins, P, inserted in corresponding slots in the sides of the heads.

P and I, and a V-shaped groove, 1 is filed into each of the said pins P. Thus when'thev V -shaped groove is worn out by constant use of the scale the respective pin P can be removed from the head of the beam P or P and replaced by anew one. In each V-shaped 4o groove P of each bearingfits the knife-edge O of a block, 0 held by the respective links 0 O, Q Q, R R, and T T. Said links are fitted over a slot, 0, in the said blockO", and

at each end of the knife-edge O, and in line 5 with the same, is formed apivot, 0, bearing against longitudinal bars I secured to projectiug lugs P on the said heads P and P by set-screws or other suitable means, thus.

holding the blocks 0 and their connectinglinks in place. Thus the links secured to the .blocks 0 are prevented from moving on account of being held inthe slots 0 and the blocks 0 are prevented from moving endwise by the pivots O, resting against the 1011- 5 5 gitudinal strips P. In the middle of each scalebeam P or P is secured a pointer, P,

pointing. on the outside of a marking-bar, P secured to the bracket B and serving to indicate the correct weight when the pointer 6 reaches a corresponding mark or line on the bar P Ea h ba -frame N or N is rovided with.

a bottom-,- l\*, on which rests the bottom of the bag, and the said bottom N is held vertically.

s di table=. t-h mes d bym ns of thumb-screws N passing through one of Each BEST AVAlLABLE cop- .vided with a lug, X adapted to engagethe rear end of the base l'l,'as shown in 'l ig. H. A crank-arm, V, is adapted to operate against the rear of the said guard N, so that thebagframe N or Nwill swing forward and beheld in place while the filled bag is being replaced by an empty one. The bag-frame N or X, respectively, is then pressed with its upper end agaiiist the lugs K oi. the hoppers it or K and the lug N is firmly pressed against the base B, so as to prevent the lHlg-fl'tllllt from moving. The crank-arm Y is secured on a shaft, V, mounted to turn in suitable hearings on the posts 1-3 and the standard 1%. A lever, V is secured on the said shaft and serves to turn said shaft so as to engage its crank-arm V with the respective bag-frame N or N or disengage it from the same.

The operation is as follows: \Yhen the machine is in the. position shown in Fig. .l, the oscillating hopper I discharges into the spout .I, so that the grain passing down the latter falls into the cone-shaped hopper K, and from the latter passes into the qvlinder 1., around which hangs the bag to be filled, so that the grain falls from the said cylinder 1. directly into the bag, resting with its bottom on the bottom N of t-h'e frame N. When the grain falls into the cone-shaped hopper. 'K, its fall is broken and the grain revolves on account of the shape of the said hopper K before it enters the cylinder I.. When the desired amountof grain has: 2l('( llllllll;ll'0(l in the bag, the bag-frame N swings downward, so that the link 0, acting on the oulerend of the head I of the scale-beam 1, causes thesaid head I to swing downward, the fillcrum being the link'Q. The other head, P", of the scale-beam I swings upward and acts by the link T on the lever I) and the arm D of the oscillating lever D, so that the latter is caused to swing to the other side. The link T -then hangs free, and the link R now engages the upper end ol. the slotted link R and the poise S is lifted to prove the accuracy of the automatic weight of the load on the frame N. The movement of the lever D causes the cylinder E to swing to the other side, so that the left-hand end of the cylinder E is thrown in contact with the arm G and causes the latter to swing to the left, so that the bar H is moved similarly andacts by its lugs II onthe pin I',-so that. the hopper Iis shifted,'and its lower end now opens .into the spout J. The cylinder E then rests with its left end on the stop F. The grain passing access intothe hopper I passes down the spout .T into the cone-shaped hopper K and into the bag suspended from the cylinder L of the frame N. The same operation as above described is repeated. The filled bag on the frame N is now removed and replaced by an empty one, whereby the poise S again causes -the scale-beam I to assume the position shown in Fi 1 as soon as the filled bag is removed. The swinging motion of the pointer U, connected with the oscillating lever D, is changed according to the weight of the bags by adjusting the thumb-screws E and E so that the movement of the said arm is increased or dim i n ishcd, and consequently more or less power is required for the scale-beams P and I to change the position of the oscillating lever D by the links '1 and T engaging the levers D and D and the latter the arms D and D of the said oscillating lever.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is g 1. In a weighing-scale, the combinationof an oscillating lever carrying a cylinder at its upper end, weigh i ng-beams loosely connected to the said lever, bag-frames supported on the beams, a pivoted grain-hopper, pivoted arms against whichthe ends of the cylinder strike, and a sliding bar to the ends of which the said arms are attached and by which the hoppeer is shifted, substantially as herein shown and described.
