WEEGHlNG-MACHINE.
SPECIFICATIQN forming part of Letters Patent No. 700,072, dated May 13, 1902.
Application filed May 1'7, 1898. Serial No. 680,977, (No model.)
rial to be weighed may be stored and drawnoff from time to time in the desired quantities and which will indicate the exact amount so drawn off.
The idea of the invention consists, essentially, in resolving the weight of the material into two components of determined proportions, one horizontal and the other at an angle thereto, and transferring the horizontal component by suitable means to an indicator.
While the idea may be carried out in a nu 1nber of different ways, I preferably use the one herein illustrated and described, in which the receptacle for the coal, grain, &c., is pivotally supported upon rods which are out of plumb, the theory being that with a certain load in the receptacle the rods can be so adjusted that one-tenth of the load will come in pressure against a dynamometer, while the other tenths Will be supported by the rods in their vertical position. In other words, the effort of the pocket or receptacle to take a normally perpendicular position would bear against the dynamometer one-tenth of its load, and then with the use of a connecting-tube and indicator the load is recorded on an ordinary pressure-gage.
Theinventiontherefore consists in the matters hereinafter described, and referred to in the appended claims.
In the accompanying drawings, forming part of this specification, Figure l is a side elevation of myimproved apparatus. Fig. 2 is a frontelevation, partially broken away; and Figs. 3, 4, 5, and 6 are detail views of the supporting-arms.
In the drawings, A represents the frame of the apparatus, and B the coal-pocket, of which one or any desired number maybe used. Said pocket is suspended from the top cross-beams 2 of the frame by suitable arms 3. These arms are pivotally supported at their ends in brackets 4,mounted upon the top of the frame work and pivotally secured at their lower ends in brackets 5, mounted upon the sides of the pocket. The pocket is further strengthened by means of suitable brace arms 6. Mounted upon the beam 7 in the rear of the pocket and in line with the pivotal connections 5 of the lower end of the supportingarms is the dynamometer O. This dynamometer may be of any suitable construction, but is preferably constructed in accordance with my Patent No. 590,046. As shown in Fig. 1, the dynamometer normally holds the pocket swung outwardly, so that the weight of the material in the pocket will exert a horizontal pressure against said dynamometer. The dynamometer is connected, as shown by dotted lines, with a suitable indicator 8, said indicator being so adjusted that the pressure caused by the weight of the pocket in itself will merely register a O indication, so that in the use of the apparatus the indicator will show the weight of the material independent of the pocket. In the drawings I have shown the floor 9 of the pocket downwardly inclined and provided at its lower end with a hinged apron 10, which is adapted to be held normally in raised position by a suitable weight 11, and a suitable slide 12 is provided, normally closing the front of the pocket.
While I have shown and described a dynamometer for the measuring of the weight, I do not confine myself to its use and may use any suitable means. The mechanical features of the construction may be otherwise Varied, as occasion requires, without departing from the idea of my invention, which is essentially, as heretofore pointed out, the resolving of the weight ofthe material into vertical and horizontal components of determined proportions and transferring the horizontal components by suitable means to an indicator.
By reference to the drawings it will be apparent that the horizontal component-il c., the pressure against the dynamometer or other restraining 1neans-will be in proportion to the sine of the angle of the supporting-arms,
and thus by increasing or decreasing the angle of said arms the pressure will be c0rre spondinglyincreased or decreased, and therefore need be but a very small proportion of the total weight of the material in the pocket. It is then only necessary to have the indicator properly adjusted to show the correct weight of the material in the pocket.
I claim- 1. The herein described apparatus for weighing articles in bulk, comprising a supporting-framework, a receptacle for the arti cles to be weighed, pivotally attached to said framework, said pivotal supports including links pivoted at their upper ends to said framework and pivotally connected at their lower ends to the receptacle, said support or receptacle being arranged entirely below the upper pivots of the links, and restraining means for holding said support or receptacle in a position to one side of the position which it would naturally assume under the action of gravity, against which means said receptacle exerts force in a horizontal line and means for measuring said horizontal pressure or force and indicating therefrom the weight placed on the receptacle.
2. The herein described apparatus for weighing articles in bulk, comprising a framework, two pairs of depending arms or links pivoted at their upper ends to said framework, a support or receptacle for the article to be weighed to which the lower ends of said arms are pivotally connected, said support or receptacle being arranged within the framework and entirely below the upper pivots of the links, said receptacle having an inclined bottom with a discharge at the lower end thereof; substantially as described.
3. An apparatus for weighing articles in bulk, comprising a supporting-framework, links pivotally hung from said supportingframework, a receptacle supported entirely below the upper pivotal connections of the links and pivotally attached at the lower ends of said links, said receptacle being sub stantially triangular in shape with a bottom inclined downwardly and having a dischargeopening at the lower end, brace-rods extending from the lower end of one pair of links and secured to the receptacle at a point adjacent its discharge-opening, and restraining means arranged in line with the pivotpoints of the links; substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
