ATTORN EYS Patented Nov. 29, 1938 UNITED STATES FATENT OFFICE 2 Claims.

My invention relates to measuring devices for use in the measuring of semi-liquids or cornminuted solids that are passed through chutes, measuring heads and the like and has for one of its principal objects the measuring of a predetermined amount of the materials and depositing the same therefrom into bags or other suitable containers.

Another object of my invention is to provide a device of the above described character equipped with adjustable means wherein the amount of the materials measured may be readily varied.

A. further object of my invention is to provide a device of the above described character which is simple in construction, positive in operation, efficient in use and economical in manufacture.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawings.

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Figure 10 is a view similar to Figure 9 illustrating the closure in another position.

In practicing my invention, with particular reference to the preferred embodiment illustrated in Figures 1 to 8 inclusive, I provide a frame 5 having top, side and bottom walls 6, 'I and 8 respectively, the bottom wall being adapted to rest upon a table 9 or other suitable support. EX- tending through the top wall 6 within the frame 5 is a chute structure l0 formed with a material discharge passage Illa extending therethrough and having upper, lower and intermediate sections II, I2 and I3 respectively of substantially square configuration in cross section. The upper section II has secured thereto a depending support member I4 and which is attached to the top wall 6 by means of a transversely extending angle iron I5.

The lower end section of the support member i4 is fashioned with an elongated slot I6 adjustably receiving a bolt Il secured through the adjacent wall of the lower section I2 and said bolt is provided with a wing nut I8 whereby to clamp the lower section in an adjusted position to the member I4. The upper end of the intermediate section I3 is fixed within the lower end of the upper section II while the lower end of the intermediate section is slidably adjustable relative to the upper end of the lower section I2 as clearly illustrated in Figure 2, consequently the lower section I2 may be adjustable relative to the upper section I I through the medium of the bolt I1 operating in the slot I 6.

As illustrated in Figures 2, 3 and 4, a wall IIa A,

of the upper section II is slotted throughout the width thereof as likewise is the adjacent portion of the member I4 whereby to receive therethrough a slide closure I9 and the oppositely disposed wall IIb of said section is provided with spaced slots I lc through which extend a pairof spaced arms integrally formed with the closure I9, the outer ends of said arms being integrally connected by a transverse section 2I. Said arms 26, closure I9 and section 2I coact to define a substantially 5 square shaped opening 22 vadapted to permit the passage of material from the upper end of the upper section I2 to the lower end thereof when the closure I9 is in open position as illustrated in Figure 3. When the closure is in closed position, as illustrated in Figure 4, the opening 20 is disposed exteriorly ozf the upper section and communication between the upper and lower ends of the upper section is closed.

It is to be noted that the faces of the closure I9 and section 2l defining the opening 22 serve to abut the embraced section of the wall Hbl and limit the opening and closing positions of the closure I9. One end of the closure VI9 has connected thereto a U-shaped member 23 to which one end of a spring 24 is secured. The opposite end of said spring is connected to a bolt 25 mounted within the lower end of a depending bracket 26 secured to the top wall 6.

A nut 2l' is secured tothe outer end of the bolt and adjustable thereon for varying the tension of the spring 24. The spring 2li serves to normally urge the closure I9 to open position as illustrated in Figures 1 and 3. The opposite end of the closure I9l has secured thereto a similar U-shaped member 28 having attached thereto one end of a cable 29 trained over a pulley 39 supported by a bracket 3| mounted on the top wall 6. The opposite end of the cable 29 has secured thereto the upper end of a springp 32 and the lower end of said spring is connected to the upper end of a rod 33 extending downwardly through an opening 34 formed in the bottom wall 8 of the frame. The lower end of said rod is connected to a pedal 35 pivoted to a supporting bracket 36 fixed to the oor or the like.

Secured to the inner face of the side wall there is a bracket 3l having a horizontally disposed end pivotally connected as at 3B to a lever 39 adjacent the outer end thereof. The inner end of said leve'r is pivotally connected to an upwardly extending rod 49 on which is adjustably mounted a sleeve il having a horizontally extending section 42 on which is pivoted the upper end of an arm 43. The lower end of said arm 43 is angularly disposed relative to the upper end thereof and is fashioned with an arcuate section 44 engaging the outer face of a gate 45 secured to said arm by means of a bolt extending Ythrough said arcuate shaped section. A spring l is secured about said bolt and is interposed between said arcuate shaped section and a. nut secured on the outer end of the bolt and coacts therewith to maintain the outer face of the gate 45 in yielding engagement with the arcu-1 ate section 44. One end of the gate 45 is equipped with a pin 48 extending through the arm 43 to prevent lateral displacement of the gate relative to the arm.

Intermediate of the ends thereof the arm 43 has pivoted thereto the lower angularly disposed end of a bracket 49 secured to the outer face of the lower section E 2k and said bracket is fashioned with an upper horizontally disposed portion 50 through which extends a rod 5l pivotally connected at the lower end thereof to the arm 43 as at 52. The rod 5| adjacent the lower end thereof is provided with a collar 53 for engagement with the lower end of a spring 54 mounted about said rodgthe upper end of said spring engaging the under face of the portion 59 whereby to normally urge the arm 43 away from the portion 59 to effect closing of said gate.

The lower end of the lower section l 2 is mitered for engagement with the inner face of the gate 45 as clearly illustrated in Figure 2. Said lower end is also provided with a housing 5l extending therebelow and fashioned with a lower reduced section 53 whereby to receive thereover the mouths of containers, bags and the like for lling by material discharged through the chute.

Secured on the rod 33 between the spring 32 and lever 39 is an adjustable sleeve 56 for engagement with the outer end of the lever 39 whereby the gate 45 is operated to open position. The upper end of the section l l is provided with a hopper 5l for receiving material to be discharged through the passage lila of the chute.

In operation of the closure i9 is normally maintained in open position and the gate 45 in closed position as illustrated in Figures l and 3. In this position material from the hopper fills the chute and is ready for discharge through the housing 5'! upon opening of the gate 45. Operation of the pedal 35 through the medium of the rod 33 and cable 23 serves to move the closure i9 to the closed position as illustrated in Figure 4 and thereby shuts oif material in `the passage Illa. above the closure I9. Continued operation of the pedal causes further downward movement of the rod 33 against the tension of the spring 32 and effects engagement of the sleeve 56 with the outer end of the lever 39 thereby causing pivotal movement of the arm 43 through the medium of the rod 49 and bracket 49. The pivotal movement of the arm 43 servesA to retract the gate 45 from engagement with the lower end of the lower section I2 thereby permitting discharge of ma terial from the passage Illa through the reduced section 55 of the housing and into a container or the like. Upon release of the pedal 35, the rod 33 moves upwardly and releases the sleeve 56 from the end of the lever 39 thereby effecting closing of the gate through the medium of spring 54. As the rod 33 movesy upwardly the spring 32 contracts and permits the spring 54 to move the closure i9 into open position. From the foregoing it will be apparent that a predetermined amount of material is contained within the chute between the closure I9 and gate 45 and that by adjusting the lower section I2 relative to the upper section Il, the amount of material to be discharged may be varied.

In the modified form illustrated in Figures 9 and the upper portion of the upper section Il is fashioned with an enlarged passage E5] and a horizontally disposed seat 6l for accommodating the closure 62 thereby enabling the closing of the gate 45 Subjacent the lower section l 2 in advance of the opening of the passage 53. In this construction, the spring 32 is eliminated and the upper end of the rod 33 is connected directly to the lower end of the cable 29.

What I claim is:
