Specification of Letters Patent.
Patented Aug. 14, 1917.
Application filed June 12, 1916. Serial No. 103,356.
To all whom t may concern.'
Be it lmown that I, HERMAN I/V. GLA- DITsCH, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, State of Oregon, have invented a certain new and useful Improvement in Sack-Filling Machines, of which the following is a specification.
My invention relates to machines for lling sacks, especially grain sacks.
The object of my invention is to provide an efficient machine operating to hold the sack, for filling, under the spout of the hopper, and simultaneously jigging the sack so as to cause the same to be compactly filled. It is also the object of my improved machine to eliminate any undue strain on the upper part of the sack, and to support the load contained therein on a support on which the bottom of the sack rests at all times.
Furthermore, instead of vibrating only the bottom end of the sack, as is commonly done in machines of this character, I have so arranged my machine as to cause thesack to be vertically oscillated or jigged throughout its length, thereby promoting the compact lling of the same.
It is further my object to make my machine adjustable to sacks of varying sizes; and it is also my object to make my machine of simple construction and operation.
The details of my invention are fully illustrated in the accompanying drawings, in which:
Figure l is a front elevation of my machine;
Fig. 2 is an enlarged fragmental sectional view taken approximately on the line 2 2 of Fig. l;
Fig. 3 is a plan view of one of the vibrating platforms;
Fig. 4L is a plan view of the gear shift lever; and
Fig. 5 is an enlarged front elevation of the devices which are adapted to support and hold open the mouth of a sack.
In the drawings I have shown my device adapted for filling grain sacks in a harvest field. For the purpose of convenience, the device will 'be housed in a transportable framed structure adapted to be positioned near the threshing machine, from which the threshed grain is delivered. In such drawings the structure is shown in more or less stripped form, but in actual use such structure will be provided with side curtains,
racks for holding empty sacks, and many other features which, while not possessing any patentable novelty, will add much to the utility and convenience of the machine.
The structure which is represented in its entirety by a, comprises a floor b, columns c, CZ, and a roof e. The floor is reinforced by the beams f, and the columns are crossbraced by steel angles g. A hopper It is provided at its lower end with two spouts i, the delivery ends of which are parallel, and permit the machine to be built in two units. If desired, the hopper could be made with any number of spouts, so that the machine could be built to a still larger capacity.
A slide valve j, provided with an operating handle 7c, is adapted to form a closure for the lower end of the hopper, so as to prevent any grain from being delivered to the spouts when the machine is inactive.
The common throat between the spouts z' and the hopper is provided with a pivoted valve diaphragm Z and an operating lever m, said valve diaphragm being so positioned that it will control the entrance to either of the spouts. In this way grain from the hopper may be directed down either spout, as desired, and prevent grain from being discharged through the other spout.
The hopper L is provided with a pair of transverse rigid bars n, the ends of which are secured to the slide rods 0. The latter are mounted in bearings p fixed on the columns d, and said rods 0 are also connected by transverse frame members Q. ,A
The frame, of which said rods form elements, is adapted to be adjusted vertically with respect to the floor of the structure. The means by which the frame is adjusted consists of the following parts: Parallel shafts r are rotatably mounted in bearings s liXed on the columns (Z. Sheaves t and sprockets u are Xed on these shafts and flexible connections o have their lower ends secured to the frame members g and their upper ends secured to the sheaves t. In this way, when the sheaves t are rotated in the proper direction, by means of a crank handle attached to the squared end of one of the shafts 1' (shown in Figs. 1 and 2) the flexible connections will Vbe wound on the sheaves and the frame correspondingly elevated. A chain drive fw, connecting the two sprockets u, cause the shafts fr to rotate together in the proper direction. The pawl and ratchet will lock said shafts against rotation in any one direction, and when said lock is released the frame will drop by gravity.
The rear slide rods 0 of the frame are connected by a rigid transverse shaft y. Pivotally supported by the latter are the arms e, said arms being. equal in number to the spouts of the machine. Each arm has rigidly mounted on its forward end a boxlike member 3, into which the lower end of the spout projects. In view of the fact that the construction of these units is identical, only one will be described herein.
A sheave yl is rotatably mounted in a bracket 5 which is bolted to a frame member 6 at the rear of the spouts. Brackets 7 are mounted on the rear columns CZ and support a transverse shaft 3, on which is loosely mounted a sheave 9, located in the same vertical plane as the sheave 4c. A flexible connection 10 has one end secured to the arm e, running thenceforth over the sheaves 4 and 9 and having its other end connected to a lever arm 11 (see Fig. 2) of the jigger element. The lever arm 11 is fulcrumed at 12 on a supporting member 13 and said lever has mounted on one end a cam roll 14, the other end being formed with a yoke 15, Pivotally supported at the ends of this yoke is a U-shaped sack-holding jigger support 16 on which the sacks 17 are placed. Said supports are provided with perforated end flanges 18, which slide on thevguide pins 19, the latter being rigidly secured on the floor The bottom of these sack holders is made with an opening 20, and blocks 21, mounted on the floor Z), are adapted to relatively enter said openings when the sack holder is rocked in the position shown in Fig. 2. In this way the middle portion of the bottom of the sack is vibrated so as to cause the material to be moved into and compactly fill said ends or corners.
The sack holder is adapted to be vibrated or jiggered at a. high rate of speed, and will act so as to violently shake the sack so that the grain may be packed therein. T he means for operating the jigger element consists of the following` parts: A power shaft 22 is rotatably mounted between the rear columns (Z. Said shaft has fixed on one end a pulley 23 adapted to be connected with a drive belt which is run either from the threshing machine, or from a separate source of power not shown.
Slidably keyed on the shaft 22 are the bevel pinions 2e, connected by a shifting sleeve which is adapted to be moved longitudinally on said shaft by the operation of a control lever 25. The operating` of this shifting mechanism is shown clearly in Figs. 2 and 4c, and comprises the following parts: A shifter 26 is provided at its lower end with a yoke 2T, adapted to engage the shifter sleeve. Said shifter is slotted at its upper end, as indicated at 2S, and is pivoted at 29 in a transverse slotted supporting member 30. The control lever is provided with a slot 31 (see Fig. el) through which extends a fulcrum pin 32, securely supported by the hopper 7L midway between the two spouts 2'., The rear end of said control lever extends through the slotted end 23 of the shifter, and 'the handle end of the lever is supported on the transverse notched bar 33, which is adapted to lock the lever so as to hold the gears 2a in either position to which they are shifted. Rotatably mounted in bearings beneath the shaft are the divided shaft sections 3l, the adjacent ends of which are mounted in a bearing on a center post Each of these shaft sections has fixed thereon a bevel friction gear 36, and the shifting of the gears 2% will place either one of the shaft sections in driving state. Each section 3l has fixed thereon a cam 37 against which the cam roller 14: is adapted to bear, and when one of the shaft sections 311 is rotated, the cam will operate to the sackholding element.
As a means for supporting the mouth of the sack, 1 have provided the device shown more clearly in Figs. 2 and 5, and which consists of the following parts: Shafts 40 are rotatably mounted in bearings a1 on the front and rear faces of the box 3. Said shafts have fixed on their outer ends the hook levers 4:2 one of which is provided with an arm 113. Said levers are connected by reversing links 41 so that when the arm 413 is operated the device will move substantially as shown by dotted lines in Fig. 2. As a means for holding' these devices in any position to which adjusted, 1 provide an expansion spring brake 415, shown in Fig. 5.
The general operation of my device is as follows: Threshed' grain fromp the threshing machine is deposited into the hopper h, either from a delivery spout or an elevator, not shown. A sack 17 is secured in position beneath one of the spouts i by placing the mouth of the sack around the box 3 (as shown in Fig. 2) and thereupon throwing the arm 43 to the position shown in broken lines in Fig. 2. r1`his movement will cause the hooks of the levers L12 to engage the bag so as to hold its mouth fully open and in elevated posit-ion. The hopper 7L is then adjusted to the proper height so that the bag will be almost fully distcnded, its lower end being supported by the jigger element. The valve Z is then operated so as to permit the grain to flow down through the spout to which the bag is attached, and the gear shifting mechanism operated so as to place the corresponding shaft section 3st in driving state, whereupon the sack igger will be actuated. This operation is continuous, and an operator can remove and seW a sack While another sack is being filled. It is to be noted that the sack is supported entirely at its lower end, so that no strain is placed on the upper end of the sack.
In the jigging operation, the jigging element is first lifted by the cam, and then dropped by gravity, and during the last movement the block 2l Will relatively enter through the openino 20 and forman abutment against which the bottom of the sack will strike, thereby causing the grain to bemore uniformly distributed and compacted in the sack. Furthermore, during the actuation of' the jigger member, the means for holding the upper end of the sack in open, uplifted position, Will be caused to vibrate in synchronism with the jigger member, by means of the flexible element l0, as shown in Fig. 2.
Then a sack of different length is to be filled, the hopper is elevated by the means previously described, so that the mouthholding means for the sack, and the sackholding seat of the jigger, will be spaced apart the desired amount.
I claim:
l. A sack filling machine comprising a hopper provided with a discharge spout, vertically oscllable means for holding the upper end of said sack open about said spout,
