SACK-HOLDER.

Specification of Letters Patent.

Patented J une 21, 1921.

Application filed January 10, 1921. Serial No. 486,270.

1 0 all whom it meg concern Be it known that I, CARL NALLnow, a citizen of the United States, and residing near San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Sack- Holders, of which the following is a specific'ation.

My invention relates particularly to that type of sacker in which the sack is automatically released by the movement of the hopper pivotally mounted on the sack frame.

It is the object of my invention to provide a device of the character indicated which will be simple in construction, economical to manufacture and positive in action.

In the drawing Figure 1 is a side elevation of my improved sacker.

Fig. 2 is a rear the saclrer.

Fig. 3 is a detail section through the tripping mechanism.

Referring more particularly to the drawing, I show a suitable frame having legs 1 and top bars 2, a hopper 3 being mounted on extensions d on rear legs 1 by means of hinges at 5.

The sack holding device consists of bar 6 pivoted to front legs 1 at 7 and passing backward between the rear legs and formed into a loop 8 at its central rear portion, the said loop 8 having a pin 9 set therein. To the sides of the bar 6 are pivoted at .10 arms 11 terminating in points 12 passing through holes 13 in bars 9 and normally held in an extended position by springs 1 1 secured to bars 2 and 6 as shown.

The device for actuating arms 11 comprises a bar 15 secured to the upper rear edge of hopper 3 by hinge 16, the said bar passing downwardly and being formed into a loop 17 norm ally engaging pin 9 as clearly shown in Fig. 3 in solid lines.

On cross bar 18 mounted on rear legs 1 is mounted a roller 19 in the path of travel of loop 17 of bar 15.

The result of this construction is that when hopper 3 is raised to the position shown in dotted lines the bar 15 is forced downwardly thereby retracting the arms 11 and releasing the filled sack. The moment, however, that the loop 17 on bar 15 engages roller 19 it is forced out of engagement with pin 9 and the springs 14 are permitted to elevation of a portion of draw bar 6 and arms 11 back to a normal posltion.

The loop 17 is replaced in engagement w th pin 9 by the dropping of the hopper after an empty sack has been placed in position, through the medium of a spring 20 mounted on bar 15 and engaging a member 21 mounted on the frame of the sacker as shown.

It may thus be seen that I have provided a new and novel means of operating sack holding mechanism through the raising of the hopper itself, and one which is not only positive in action but simple in form and operation and economical to manufacture. The bar 15 passes under or through member 21 and spring 20 is so arranged that upon the downward movement of bar 15 the spring moves clear of member 21 and bar 15 is easily moved outwardly by contact of loop 17 with roller 19. Upon the closing of the hopper and the upward movement of the bar 15, however, the spring 20 reengages member 21 and forces bar 15 inwardly again so that loop 17 readily engages pin 9 when the hopper is closed.

It is to be understood of course, that while I have herein shown and described one particular embodiment of my invention changes in construction and method of operation may be made within the scope of the appended claims.

I claim 1. A supporting frame, a hopper pivotally mounted thereon, sack engaging pins mounted thereon, pin actuating means pivotally and resiliently mounted thereon and pivotally connected to said pins a depending bar pivotally mounted on said hopper and movable downwardly by the raising thereof and having a loop formed on its lower end, a detachable connection between said loop and said pin actuating means, and means mounted on said frame in. the path of travel of said loop whereby the connection between the loop and the pin actuating means is separated on the downward movement of said bar and loop.

2. A supporting frame, a hopper pivotally mounted thereon, sack engaging pins mounted thereon, pin actuating means pivotally and resiliently mounted thereon and pivotally connected to said pins, a depending bar pivotally mounted on said hopper and movable downwardly by the raising thereof and having a loop formed on its lower end, a

detachable connection between said loop and said pin actuating means, means mounted on said frame in the path of travel of said loop whereby the connection between the loop and the pin actuating means is broken on the downward movement of said bar and loop, and means mounted on said frame for effecting the reengagement of said loop and pin actuating means upon the upward movement of said bar and loop. v

3. A supporting frame, a hopper pivo-tally mounted thereon, sack engaging pins mounted thereon, pin actuating means pivotally and resiliently mounted thereon and pivot- 1 ally connected to said pins, a depending bar pivotally mounted on said hopper and movable downwardly by. the raising thereof and having a loop formed on its lower end and a spring member mounted on its outer surface, 2 a roller mounted on said frame to engage said loop and disengage the same from said pin upon the downward movement of said bar, and a member mounted on said frame to engage said spring member and effect the 2 reengagement of said pin and loop upon the upward movement of said bar.
