Application filed'll'pril 9, 1914; Serial No. 830,570.

To all whom it may concern. v

Be it known that I, FRANK M. HEWsoN, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Measuring- Machines, of which the following is a specification. I

This invention relates to new and useful improvements in measuring machines. a

The object of the invention is to provide a machine of the character described whereby such articles'assugan, coffee, grains and like articles may be measured into predetermined quantities and then delivered into bags or sacks in which they are sold to customers. I

A further feature of the inventionresides in the provision of a construction whereby the goods to be measured may be measured in large or small quantities, as may be desired. l

With the above and other objects in view, the invention relates to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein-- Figure 1. is a side elevation, partially in section, of the complete device. Fig. 2 is a fragmentary view of the operative mechanism thereof. Fig. 3 is a fragmentary vertical sectional view of. the telescoping measuring chamber, and Fig. 4 shows a plan view of the form of gate employed.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, thenumerals 1. and 2 refer, respectively, to the top and bottom of the frame work, which are fixed in relative position by means of suitable sidebeams, such as 3. The top of the frame work carries a large funnel shaped bin 4 in which the merchandise to be measured is stored in bulk and the lower end of this bin is normally closed by means of a sliding gate, such as 5. Fastened to and depending from the lower end of this bin is a measuring chamber composed of

tubular telescoping sections

6, 7 and 8, the lower end of each section having an outwardly extending flange and the upper end of the two lower sections each having an inwardly extending flange, the corresponding outwardly and inwardly extending sections inter-engaging, as shown in Figs. 1 and 3, so as to prevent said sections from entirely separating. The lower end of this measuring chamber is normally closed by means of a sliding door, desig nated by the numeral 9, but in construction similar to the sliding door 5. The lower end of the section 8 is slightly tapered or funnel shaped, so as to direct the material being measured into the container receiving the same. Each of the sliding doors 5 and 9 has an enlarged orifice, such as 10 therethrough, so as to permit the material to pass therethrough when the door is properly adjusted, as will be hereinafter explained. A lifting rod 11 is provided, which extends transversely and one end thereof is bifurcated, the fingers thereof embracing the section 8 andbeing pivoted thereto on each side and the other end of this rod has twosliding

bearings

12 and 13 through which the parallel vertically extending

rods

14 and 15 pass, the upper and lower ends ofthese rods, respectively, beingfixed to the

supports

16 and 17. A crank shaft 18 is provided which extends transversely of the frame and rotates in the bearings 19 and 20 and has the wrist 21. A link 22 is provided, the lower end of which has the bearing 28 through which the wrist 21 passes and the upper end of said link is forked, having two prongs, the free ends of said

prongs having bearings

24, 24 through which the lift rod 11 passes. Fixed to the bottom frame Work '2 is a rack 25 and pivoted by said rack is the hand lever 26, said hand lever being equipped with the dog 27 whose lower end normally engages with said rack and locks said hand lever against movement but which may be disengaged from said rack, in the ordinary and well known manner, so as to permit said lever to be moved back and forth. One end of the shaft 18 has an arm 28 fixed thereto at one end and the other end thereof has a sliding engagement with the hand lever 26. When the dog 27 is disengaged from the rack 25 and pulled outwardly in the direction indicated by the arrow in Fig. 2, it will operate, as is obvious, through the mechanism just described to force the lift rod 11 upwardly, carrying the section 8 upwardly with it and lessening the capacity of the measuring chamber. When the hand lever 26 is moved in the opposite direction the lift rod 11 will be pulled downwardly and the capacity of said chamber increased.

In operation the lever 26 is manipulated until the desired capacity of the measuring chamber is attained and there locked in position by means of the dog 27. The sliding door 5 is then pulled outwardly until the orifice 10 thereof is brought underneath the lower end of the bin 4 and the material in the bin will be permitted to pass down into the measuring chamber, the lower end of which is closed by means of the door 9, and said chamber is permitted to fill and said door 5 then moved backwardly until the lower end of the bin is closed. The sliding door 9 may then be pulled out until the orifice therein comes under the measuring chamber and the contents of the measuring chamber will pass into a bag or other container which has been previously placed underneath. By alternatively moving said doors 5 and 9, as hereinbefore explained the entire contents of the bin may be measured into packages of equal quantities, the amount contained in each package being governed by the previous setting of the hand lever 26. The respective doors 5 and 9 are provided with

grips

29 and 30, by means of which they may be manipulated and the ends of said doors opposite the handle are flanged, so as to prevent their complete withdrawal from the grooves in which they slide.

I have shown and described only one form of this device but it is obvious that various mechanical modifications may be made therein and the same purpose accomplished and I hereby reserve the right to make such mechanical modifications therein as will not depart from the scope of the appended claims.

What I claim is 1. A device of the character described including a frame work, a funnel shaped bin carried thereby, a measuring chamber secured to and depending from the lower end of the bin, said chamber being formed of tubular telescoping sections, adjustable relative to each other, a mechanism having operative connection with one of said sections whereby said section may be adjusted so as to vary the capacity of the measuring chamber, said mechanism including a hand lever, a means for locking said lever, in a fixed position, a means for releasing said locking means, a transverse lifting rod, one end of which is pivoted to said last mentioned sections and the other end of which has a slidable engagement with the framework, and a I crank shaft rotatably mounted in said frame and having an operative connection with said hand lever whereby said crank shaft may be partially rotated and a link, one end of which is pivoted to the wrist of said crank shaft and the other end of which is pivoted to said lifting rod, and means controlling the discharge of material into and from said measuring chamber.

2. A measuring machine comprising, a frame work, a bin carried thereby, a measuring chamber depending from the lower end of the bin, said chamber being formed of telescoping sections, a mechanism having operative connection with one of said sections, whereby said section may be adjusted, so as to vary the capacity of the measuring chamber, said mechanism including a hand lever, a means for locking said lever in fixed position, a means for releasing said locking means, a transverse lifting rod, a crank shaft, rotatably mounted in said frame and having an operative connection with said hand lever, whereby said crank shaft may be partially rotated, and a link, one end of which is pivoted to the wrist of said crank shaft and the other end of which is pivoted to said lifting rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
