GRAIN-BAG HOLDER.

Specification of Letters Patent. P te ted Apr. 13, 1920.

Application filed July 6, 1918. Serial No. 243,543.

To all whom it may concern:

Be it known that 1, WILLIAM JAHNS, a citizen of the United States, residing at Marathon, in the county of Marathon and State of lVisconsimhave invented new and useful Improvements in Grain-Bag Holders, of which the following is a specification.

This invention relates to improvements in grain bag holders.

In carrying out my invention it is my purpose to produce a grain bag holder which will firmly grip the bag and which is adjustable both vertically and laterally to engage with various sizes of bags.

It is also my purpose to produce a grain bag holder of a comparatively simple construction wherein the bags may be easily attached thereto and firmly supported thereby and also wherein a shaking movement may be imparted to the bag to settle the grain delivered therein.

Other objects and advantages of the improvement will appear in the following specification and will be pointed out wlth particularity in the appended claims.

In the drawings, accompanying this speci fication there has been illustrated a simple and satisfactory exemplification of the improvement, in which,

Figure 1 is a perspective view showing a grain sack secured upon a holder construct ed in accordance with my invention.

Fig. 2 is a top plan view, the sack being removed.

Fig. 3 is a front elevation of the same.

Fig. 41 is a sectional view approximately on the line 4-4: of Fig. 1.

Fig. 8 is a sectional view approximately on the line 88 of Fig. 2.

Fig. 9 is a detail sectional view approximately on the line 99;of Fig. 3.

Fig. 10 is a perspective view of the clamp.

Fig. 11 is a perspective view of one of the jaws of the clamp.

The improvement contemplates the employment of a base formed of two spaced elongated pieces or beams 10 each having an oppositely disposed upstanding standard. The standards 11, while disposed near the center of the beams or foot pieces 10 are 7 supported by angle braces 14.

The inner faces of the wall of the standards 11 are provided with alining vertically disposed elongated slots 15 receiving therein the ends of a beam or plate 16 that is secured to the lower 'ends of side members 17 arranged in the slots 15, but extend above the standards. The members 17 provide the sides of what I will term the lower frame of the device, the plate 16 provides the lower member of the frame and the upper connecting member for the sides is indicated by the numeral 18.

The sides 17, at the portions thereof received in the slots 15 of the standards are provided with vertically disposed elongated openings 19, and journaled in suitable bearings provided by transverse openings in the upper ends of the standards 11, and passing through the said openings 19 is a shaft 20. This shaft is held against longitudinal movement by suitable collars 21 secured thereon and contacting with the outer faces of the standards 11. One end of the shaft is offset providing the same with a crank 22, and secured to this crank is a link .23 that has its lower end loosely connected, as at 24: to a foot pedal 25, the inner end of which being pivotally secured as at 26 to one of the foot members 10. The shaft 20 has keyed or otherwise secured thereon toothed segments 27 one of which being disposed adjacent to the inner face of each of the standards 11, while secured to the plate 16 are rack bars 28 which are engaged by the toothed segments. These rack bars are guided through suitable socket members 29 secured to the connecting mem ber 13 for the standards 11. By this arrangement it will be seen that a pressure upon the pedal 25, in a downward direction will cause the frame to be moved upwardly of the base of the device and a release of such pressure will permit the frame, by the weight thereof resuming its initial position by dropping or gravitating downwardly in the slots 15 of the standards. The pedal, it will be thus seen serves as a means for agitating the frame, and for the i an .the upper frame m such adjustment.

sake of convenience the frame willhereinafter be referred to as the lower frame section.

The upper frame section is broadly indi- 'cated by the numeral and includes flat side members 31 ofa size corresponding to that of the side members ofthe lower frame The inner faces of the sides of the upper frame contact with the outer faces of the sides of the lower frame, yokes 32 being secured on the sides 31 and surrounding the sides 17 of the lower frame. If desired the yokes maybe centrally provided with antifrictional rollers 33 received in-and contacting with the side walls of elongated slots 3 f on the side members 17 of the lower frame.

The sides 31 of the upper frainecare pro-i vided withelongated slots or openings arranged in parallelism and extending longitudinally of the said sides. One of the side "walls provided by each of the openings 35 is formed with. or has secured thereon a toothed rack 36. Journaled in suitable bearings 37 on the top member 18 of the lower frameis a shaft38. On this shaft is keyed orotherwise securedpinions 39' that engage with the teeth of-the racks 36. The shaft projects through the openings in the sides of the upper frame. and in the preferred construction of the invention, as illustrated by the drawings the toothed racks are arranged nearer the outer face than the inner face of the side members, and sleeves 40 are formed on the inner faces'of the pinions 39, the sain sleeves contacting with the opposite walls provided by the openings 35 and as a consequence the said sleeves provide a bearing support for the upper frame so that the slots in the lower frame and the antifrictional rollers on the yokes are not absolutely essential.

On one end of the shaft '38 is, secured a ratchet wheel ll. The teeth of this wheel are engaged bya dog 42. The dog is formed angularlyon one end of a rod 3. The rod is j ournaled'in bezwings tfl on'the inner edge of the upper connecting member for the lower frame, and the inner end of the rod is arranged at an angle to provide a handle as. A spring is secured to the upper connecting member of the lower frame and :tothe-handlel-5 to retain the handle in one position and the dog in engagement with the ratchet wheel. The outer or serond end of the shaft 38 is provided with a crank handle {137. By this arrangement it will be seen that ay be adjusted vertically with respectto =thelower frame and held iii The release of the dog from the ratchet wheel will permit of the upper frame gravitating downwardly over the lower :frame, so that proper adjustments betweenthe frames may be readily obtained.

'llheside members 31 of the upper frame,

at the upper edges thereof, and upon what I will'term the outer face of the device, are connectedby a flat vertically disposed plate 4L8 This plateyupon its outer face'may' be formed with a longitudinal groove, and the opposite walls provided by the groove may be slotted longitudinally, or, if desired, and

' as illustrated by the drawings, lipped plates :9 may be secured to the outer face of the plate 48. The lips of these plates are formed upon the confronting edges thereof 7 and provide ways for the rectangular body portions of the bag holdingclamps. The body of each of the clamps'is formedwith or has secured upon its outer face :a right angu- "lar bracket 51, and the lower edge of each being longer than the outer stud, and between the studs the jaw is provided with springs 55. The center and longer stud 54 hasits end up set as at 56. This up set end is p referably threaded. V

The outer jaw of each of the clampscomprises a flat plate 517 having openings 58 therein through which the studs project. The outer jaw is hooked by the springs so that the same is normally'held away fromthe inner jaw. Theouter jaw, adjacent'the lower edge thereof is depressed longitudinally from its opposite sides forming the same with an inturned U-shaped projection 59 and a U- shaped depression 60. These corrugated portions of the upper jaw are designed to co-engage with corrugated portions '52 and 53 of the inner jaw when the outer jaw is brought against the inner jaw. 'On the up set 56 of the central stud is j ournaled a cam ()1 having a handle 62. Preferably this cam is formed of strap iron bent or coiled upon itself to provide the cam surface and the handle. It will be apparent'that by operating the handle the cam 61 will be brought to contact with the outer face of the outer jaw moving the same against the pressure of the springs into contact with the inner jaw. It will be further noted, by reference to the drawings that the corrugated surface of the inner jaw is disposed a considerable distance below the bracket on which the said corrugated surface is formed so that ample roomisprovided for the edge of the sack 63 when the same is clampedbetweenthe jaws. On the plate or connecting member for the sides of theupper frame, above the upper edge of 'the said plate is arranged a a longitudinally disposed guide rod 65 the offset ends of which. being connected to the said plate -in any desired or preferred manner. On the guide rod is arranged for slidable

movement apron plates

66 and 67 respectively. Each of the plates, upon its upper edge is rounded inwardly upon itself to provide the same with a barrel 68 which is received on the guide rod 65. It is to be noted that each of the barrels 68 is extended from the outer end of the respective apron plates less than one-half the length of the aid plate and that the plate 66 has its upper edge lapping the plate 67. The outer edges of the plates are bent upon themselves providing the plates 66 with a cross sec tional U-shaped groove 69 and the outer edge of the plate 67 with a rib 70 which is received in the groove 69. By this arrangement a tight joint is retained between the plates, but the said plates may be folded one over the other, when the clamps are ad justed longitudinal of the upper frame, in a manner which will presently be described. The body plate of each of he clamps, or if desired the bracket on each of the body plates has arranged thereon a hook 71, and each of the apron plates, adjacent the outer edge thereof is provided with a slot 72 receiidng the respective hooks. By this arrangement the apron plates are not only detachably connected with the clamps but are retained at a desired inclination with respect to the clamps and with respect to the frame. The plate 66 has its inner edge notched as at 73, the notch being arranged in a line with the hook 71 which engages the apron plate 67., so that the plate 66 can slide to fully cover the plate 67, when the clamps are adjusted for a very small sized sack.

Secured to the connecting plate for the sides of the upper frame is a rack 7st. The rack is extended over the end of the device on the side thereof provided with the foot pedal and. with the crank end of the shaft 38. Preferably the rack is in the nature of a flat slotted plate and one of the edges provided by the said slot is formed with the rack teeth. In the slot of the rack plate is arranged a lever 75, the same having transverse lug 7 6 which contacts with the upper face of the rack plate to hold the lever thereon. The lever has one of its edges provided with an elongated inturned. portion forming a tooth 7 7 that is designed to co -engage with the rack teeth. The lower end of the lever is rounded inwardly and is provided with spaced openings. The upper opening receives the offset end of a short link 78 which loosely connected to the clamp nearest the lever, while the lower opening receives the offset end of link 79 that is loosely connected to the second clamp. The slot in the rack plate, through which the lever passes permits of a lateral movement of the lever to bring the tooth thereof into or out of engagement with any of the teeth of the rack, and by proper ad justment of the lev r with respect to the rack the tooth of the lever engaging with a certain tooth of the rack permits of a quick and accurate adjustment of the clamps with respect to each other, and by properly fulcruming the lever on the tooth rack one of the clamps may be moved toward or away from the other without influencing the last referred to clamp.

The apron properly directs the grain to the sack preventing the same filling the ways in which the clamps slide. By operating the foot pedal or lever the grain in the sack will be agitated to cause the same to properly gravitate to the bottom of the sack and so level the grain in the sack. The device can be operated by a single hand, and is portable. It .is thought, from the fore going, when taken in connection with the drawings that the construction and operation of the device will be fully understood, and a more detailed description thereof will not be necessitated.

Having thus described the invention, what I claim is:

1. In a grain sack holder, a base, a sectional frame thereon, adjusting means between the sections of the frame, agitating means between the base and frame, longitudinally adjustable clamps carried by said frame, a hinged collapsible apron on the frame between the clamps, and connecting means between the sections of said apron and the respective clamps.

2. In a grain sack holder, a base, a sectional frame supported by said base, means for reciprocating the frame, one section of the frame having its sides lapping the sections of the other section, yokes secured to the upper section and surrounding the sides of the lower section, means carried by the lower section and co-engaging with the up per section for vertically moving the latter, stop means for said adjusting means, spaced slidable clamps on the upper section, and a collapsible apron on the frame between the clamps.

3. In a grain sack holder, a base, a sectional frame supported on said base, means between said frame and base for imparting a reciprocatory movement to the frame, means for adjusting the sections of the frame with respect to each other, means for retaining said sections in alinement, clamps on the upper section and a collapsible apron between the clamps.

in testimony whereof I affix my signature.
