{PATEN em f RAIN-MEASURE;

SPECIFICATION forming part 0; Letters latent No. 381,350. dated April 1-1, 1888.

Application filed December amiss-usual No. 259,333, (No model) 1 of Minnesota, have invented certain new and useful Improvements in Grain-Measurers, of which the following is a specification, reference being had therein to the accompanying drawings. 7 7 7 This invention relates to means for measuring grain and the like,wherein two alternatelyreciprocating slides or cut-offs are employed in combination with a supply hopper, an intermediate receptacle between the slides, and a contracted neck to which a'bag can be conveniently attached or detached.

The gist of my invention consists in improvextending the lower walls of the hopper down wardly and inwardly to afford a close bearing for a sliding cut-off; also, to extend thewalls of the intermediate receptacle into the chute or bag-holder to afford a close bearing for the lower slideor cut-off, all of which will be fully understood from the following description and claims, taken in connection with the annexed drawings,,in whicha 1 Figure 1 is a perspective view of my improved grain-measurer. Fig. 2 is' a vertical central section thereof, the upper portion of the hopper of which is broken away.

Referring to the annexed drawings by letter,

A designates a hopperhaving inclined sides a a, converging downwardlyand terminating in bearings a a, against-which a sliding out-off, D, bears, which slide is guided by two vertical cheeks, b b, as shown in the annexed drawings.

aperture, 6, through it, through which passes freely the upper fcurved end, f, of a vibrating lever, F, which is connected by a boltandnut, n, to a rocking'bar, G, which is fulcrumed in arms N, rigidly secured to the sides of the measuring-receptacle B. It willbe observed that the bolt it passes through a slot, 8, through thelever F also, that the lower curved end, f, of the lever F is passed freely through a slot,

e, made through the outer part of a secondary slide, H, which is free to reciprocate through the chute O, and which is in close relation to the contracted ends a c of the rece'p'tacleB.

The lower end of the chute G is preferably provided with means fortheattachment'of a ':bag into which the grain or other measuredmaterial is discharged.

' It' will be observed that the lever]? is a .justabl'e endwise,by means of the slot and'the 'bolt-and-nut connection, with the oscillating fulcrum-barG. Theobject of this connection is to prevent the possibility of binding at the points e e, so that the sliding cut-offs shall re-- ciprocate smoothly through'th'e body of, the

measuring device.

It is essential to the practical working-of the device that the'ends'of the vihratinglever F shouldbe curved, as indicated at f f, for

the purpose of accommodating themselves to the rectilinear movements of the two slides without causing'the parts to bind. It'is also essential that said lever should be adjustable .endwise on the oscillating bar G' for the purpose of nicely adjusting this lever to the said slides, the lever serving as the means for transp mitting movements from the lower sl'ide'to the r I r I r; T75

It will be observed that the lower ends of upper'slide or cut-off.

the sides a a of the hopper-and the sides of the receptacle B afford narrow bearings'for their respective slides, and leave clearing-spaces t t, which will effectually prevent lodgment of hand-grip, E, by means of which a personfcan alternately reciprocate the two slides and graduate the flow of grainor other material from the hopperA through the receptacle BI and chute G lntoa bag or other suitable. re-

ceiver. It will finally be observed that the lower termini of the hopper and the receptacle B arecontracted, so as to afford independent upper bearings for the two slides,-and also guides therefor, which direct the material being measured toward the centers of the-discharge-hopper and chute.

Having thus fully described my invention, i I

what I claim as, new, and desire to secure by Letters Patent, is-

1, In a grain-meter,'the combination, with ice the hopper A, the chute O, the intermediate enlargement, B,and the two rectil inearslides 8o small grains, &c., between said bearings and D H, of the rocking bar G, its bearing-arms, and a slotted vibrating lever, F, endwise adjustable on said bar and provided with curved ends freely engaging with the said slides, sub- 5 stantially as and for the purposes described.

2. The combination, in a grain-measuring device, of a hopper having inclined sides aa, terminating at a a in narrow bearings below theupper end of cheeks b b, the enlarged re a ceptacle B, also terminating in narrow bearings c 0 below the upper end of the chute G,

the said bearings leaving clearing-spaces t t, the slides D H, and a lever, F, having hooked ends engaging loosely with both of said slides and endwisc adjustable on a rocking bar, G, 15 substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
