UNITED STATES ATENT OFFICE HAND HOIST SACK FILLER Edward Welsh, Hatley, Wis. 7 Application February 27, 1946, Serial No. 650,561

5 Claims. (01. 226-58) This invention relates to a sack filling device and it consists in the constructions, arrangements and combinations herein described and claimed.

It is a particular object of the invention to provide a mobile scoop device which may be manually moved into material to be sacked, elevated and discharged into a sack or other receptacle. It is a still further object of the invention to provide a sack filling device of verysimple construction embodying skid runners whereby the device may be readily moved and in which a sack to be filled may be supported in a manner to readily receive the material from an elevated scoop, all of which may be readily operated by a single workman.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein,

Figure l is aperspective view of the device illustrating its initial operative loading position.

Figure 2 is a side elevation of the device in position for discharge of the contents of the scoop device into a sack,

Figure 3 is an enlarged fragmentary top plan view illustrating the pivotal mounting of the scoop device,

Figure 4 is a cross section illustrating the mounting of a support for a sack to be filled.

Figure 5 is a fragmentary bottom view of the conveyor tube.

Referring to the drawing, there is illustrated a skid frame I0 consisting of a pair of elongated runners ll connected in spaced parallel relation by means of suitable transverse braces 12.

Upon each of the runners I I there is an upright l3 positioned rearwardly of the rearmost brace 12, each upright terminating in a bearing I4 for support of a shaft l5 for a purpose presently to be described.

Between the uprights l3 and a forward end of the runners l I, a brace rod I6 is secured by bolts, welding or otherwise, to afford rigidity to the structure.

The shaft [5 is held stationary in the bearings l4 and at a medial point of the shaft there is mounted an elongated tube ll of suitable diameter, by means of a cradle presently to be described. The tube II is rockably supported upon the shaft, in the present instance, a collar !8 is illustrated secured to the outer periphery of the tube, and at the lower periphery of the collar 18, trunnions H! are provided through which the shaft is extended.

The cradle for support of the tube is defined by a pair of operating arms 2!! which are also rockably mounted upon the shaft l5, disposed upon respective side of the tube ll, these arms extending forwardly to a point substantially the length of the front portion of the runners II where they are connected by a transverse plate 2!. The forward or scoop end ll of the tube H rests upon the plate 2! and is secured thereto by means of a clamp collar 22. The arms 20 extend rearwardly beyond the uprights 13 a substantial distance and terminate in hand grips 23. A handle bar 24 is connected to the arms 20 a distance inwardly of the hand grips and are suitably braced as at 25. The handle bar, extends upwardly a suitable height so as to provide ample leverage to effect tilting movementof the cradle and associated parts with a minimum of effort.

A scoop 26, which may be of any suitable construction with respect to its forward edge, depending upon the material being handled, is detachably mounted at the scoop end ll of the tube. In the present instance, this is accom-,- plished by providing the rear end of the scoop with a contour corresponding to the circumference of the tube. With this part of the scoop disposed upon the tube and resting upon the plate 2!, the clamp collar 22 will hold the scoop in proper rigid position in advance of the tube so as to feed material thereinto.

An annular ring 21 is rigidly fixed to the shaft l5 by means of bolts or rivets 28, the ring extending in a horizontal plane and centralized with respect to the discharge end 29 of the tube. In order to suspend a bag 30 or similar container from the ring in an open receiving position, suspension hooks 3| are formed upon the periphery of the ring.

In use, it being assumed that the parts will be in the position shown in Figure 1, the scoop 26 resting upon the floor where material to be sacked is deposited. The device is advanced toward the material by exerting a pushing movement on the handles 23, the runners II moving easily and smoothly upon the floor, until the scoop 26 engages the material. Further advancing movement of the device will cause material to move into the scoop and thence into the tube by way of the open end H. The device may be retracted and advanced into the material until a desired amount of material has been forced into the tube. Now, in order that the material may be transferred to the sack 30,

and exert a downward pull, thus elevating the tube to the position shown in Figure 2, when the material will move along the tube and discharge into the sack. The operation is repeated until the sack is filled, which may then be removed and an empty sack is then placed upon the ring 21 and similarly filled.

On occasion it may be desirable to screen the material before being sacked, and in Figure 5, I have shown the tube with a portion of the bottom wall as a screen element 32. It will be apparent that as the material passes over the screen member, undesired particles will pass outwardly of the tube. When the screen is not required, the opening 33 in the tube may be closed by a suitable plate by bolts engaged in the threaded openings 34.

From the foregoing description it will be seen that I have provided a device which may'be'operated to quickly fill sacks by a single workman and this is accomplished without theneed for back bending exertions'as required by present day practices. c

j While I have shownand described a preferred form-of the device, this is by way of illustration b lly and I consider as my own, all such modifications-in construction as fairly fall within the scope of the appended claims.

Z. la I ,1 c f l In a hand hoist sack filling device, a pair of: parallel runnermembers, an upright on each runnermeinber, a transverse shaft fixed in the upper ends of L each upright, a cradle rockably mounted on "said-- shaft, an elongated tube disposed medially of said shaft and having one end rockably mounted thereon, said cradle includinga plate for rigid securementof the other endor said tube, a scoop carried by said other end of the tube, handle means associated with saidcradle to move the device so as to present the scoop into material disposed upon a floor or-' the like, a sack detachably connected in ad- Vance of the 'rockably'connected end of the tube and a handle bar connected with said cradle for tilting said tube. a l
