DISINTE GR ATING-TOOL FOR SUGAR IN BARRELS.

SPECIFICATION forming part of Letters Patent No. 545,878, dated September 10, 1895.

Application filed March 21, 1895. $erial No. 542,578. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN DENNISON, a citizen of the United States, residing at Fort Wayne, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Disiutegrating lools for Sugar in Barrels; and I do hereby declare that the following is a full, clear, and exact de scription of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in disintegrating-tools for sugar in barrels. It is well known that sugar. put up in barrels soon becomes, when opened and in the hands of retailers, a solid, compact mass, often impenetrable not only to the retailing scoop but also to an ordinary tool, and in this condition is extremelydifficult andinconvenient to handle.

The object, therefore, of my invention is to provide a cheap, substantial, and easily-operated tool adapted to disintegrate and loosen up a compact mass of sugar in barrels by relieving the mass of its lateral support at diametrically-opposite points by an outward pressure against the sides of the barrel simultaneous with the disintegrating action of a pair of rotary cutting blades or wings upon the lower end of the operating-shaft.

Myinvention comprises an externally screwthreaded shaft carrying upon its lower end an operating-handle and having adjustably mounted thereon a pair of radial oblique arms adapted to secure an outward pressure upon diametrically-opposite points on the perimeter of the containing-vessel.

Similar figures of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of my improvement, showing the relative position of the operative parts with a portion of one of the oblique arms broken away to show its pivotal connections. Fig. 2 is a plan of one of the oblique arms, showing the parallel members and their rigid connection. Fig. 3 is a plan of the two-bladed rotary cutting-knife. Fig. 4 is a plan of the screw-threaded collar in which the inner ends of the toggle-levers are pivotally mounted. Fig. 5 is a plan of the slidable collar in which theinner ends of the obliquelever-arms are pivoted. Fig. 6 is a side view of my improvementin position in a sugarbarrel, showing the simultaneous action of the oblique lever-arms and the rotary cuttingblades upon the compact contents thereof.

All parts of my improvement excepting the handle are preferably of metal.

The vertical operating-shaft l is externally screw-threaded throughout its length, excepting at its extremities, has upon its lower end a cone'shaped point 15 and upon its upper end a hollow cylindrical head 16 in which the operating-handle 21 is removably mounted, and is provided with a neck 17 integral therewith.

The oblique arms 2 are formed of two substantially-parallel bars, as seen in Fig. 2, having their outer ends slightly spread and rigidly connected by the pin 13, thereby giving them greater strength and a bearing against the barrel sides at two points for each arm. The outer end of the said bars are preferably claw-shaped to give a firm grip when in position for spreading the sides of the barrel. The arms 2, thus constructed, are pivotally mounted at their inner end upon diametrically-opposite sides of the slidable collar 7 by means of the perforated lugs 8 and the pins 11. The said collar7 is loosely mounted upon the said shaft 1, and is limited in its upward movement by the screw-threaded thumbnut 6 on said shaft. The said shaft 1 is provided at or near its lower end with a collar 9 mounted thereon by a screw-threaded connection, and provided upon its opposite sides with apair of lugs 20, in which the lower ends of the oblique toggle-levers 3 are pivotally mounted by the'pivots 10, the outer and upper end of the said levers 3 being pivotally connected to the oblique arms 2 by the pins 12 at a point preferably about midway their length. The said shaft is also provided at its lower extremity with a knife rigidly mounted thereon, and provided with the oppositely-arranged horizontal cutting-blades 4 and 5, the cutting-edge of each being upon the side opposite to that of the other, as seen in Figs. 1 and 3. The said knifeis removably mounted in position on said shaft and is rigidly secured thereon by the jamnut 14. The blade 4 is preferably twice the length of the blade 5, and the cutting-edges of the said blades are arranged upon different planes, so that the shorter blade 5 outs in advance of the blades 4.

The manner of operating my improvement thus briefly described is as follows: The tool is placed in position in the top of the barrel 18, as seen in Fig. 6, with the point 15 inserted into the center of the contents 19. The arms 2 are then spread until their outer claw-shaped ends impinge upon or grip the sides of the barrel. This is done by lowering the slidable collar 7 supporting the upper ends of the said arms by means of the screw-threaded nut 6, and when desired the sides of the said barrel can be still farther spread by a further lowering of the said nut on the said shaft. The spreading of the sides of the said barrel in one direction will thus relieve the compact mass of its corresponding lateral support and will also simultaneously compress the said mass with equal force upon its opposite sides, thus tending to break it up, and the mass will thus offer less resistance to the action of the cutting-blades. The operator.

now rotates the said screw-shaft 1 by means of the operating-handle 21, being rigidly supported in its upright position by the said oblique lever-arms 2. The rotation of the said shaft carries with it the fixed cuttingblades 4 and 5, adapted to cut concentric openings, preferably of a diameter of eight and sixteen inches respectively. The spreading action of the said arms upon the containing-barrel thus materially contributes to the ease and facility with which the hard and compact mass 19 is broken up and disintegrated. It is obvious that the rotation of the screw-shaft 1 in operating the said cuttingblades will in no wise affect the relative position of the said collars 7 and 9 thereon, nor affect in the least the outward pressure of the said arms 2, though, of course, the revolution of the said shaft will constantly vary the relative position of the supporting-collar 9 and the said cutting-blades 4 and 5.

When it is desired after the above operation to remove my improvement from its'fixed position in the said barrel, it can be readily done by simply rearwardly rotating the said thumb-nut 6 on the shaft 1, and then slightly elevating the said slidable collar 7, when the arms 2 will relax their hold and the tool can be lifted out. By arranging the said thumbnut 6 upon the neck 17 of the shaft 1 the said arms 2 and the toggle-levers 3 can be folded into a position practically parallel with the said shaft, and by removing the handle 21 and the said cutting-knife, my improvement can be packed into a convenient and compact form for shipment or storage. It is obvious that the mere form and proportions of the said cutting-blades and of the said oblique arms 2 are immaterial and may be variously modified in various details of construction without departing from the spirit of my invention. It is also obvious that my improvement is equally well adapted for disintegrating salt in barrels and numerous other articles of merchandise.

Having thus described my invention, what I desire to secure by Letters Patent is 1. A disintegrating tool for the purpose specified, comprising a screw threaded rotary shaft having upon its lower end the rigid cutting blades 4 and 5, apair of pivotally mounted oblique arms, mounted as shown, for the.

purpose described, and provided with the toggle levers 3 pivotally mounted in the screwthreaded collar 9, all substantially as described.

2. In a disintegrating tool for sugar in barrels, the combination of the screw threaded shaft 1 having an operating handle in the top thereof, the cutting blades 4 and 5 removably fixed upon the lower end of said shaft, the oblique arms 2 ptvotally mounted in the slidable collar 7 on said shaft, the toggle levers 3 pivotally mounted in the screw-threaded collar 9 and having their upper end pivotally connected to the said arms, and the screwthreaded thumb-nut 6 adapted to vertically adjust the said collar 7 on said shaft all substantially as described.

3. In a disintegrating tool for the purpose specified, the oblique arms 2 pivotally mounted at their upper end in the slidable collar 7, and pivotally supported at their central portion by the levers 3, and having at their free end a claw shaped termination to secure a holding grip upon the sides of the barrel in which it is placed, the toggle levers 3 pivotally mounted in the screw threaded and vertically adjustable collar 9, and having their outer ends pivotally connected to the arms 2 as shown, and the screw threaded thumb-nut 6 adapted to adjust and secure the said collar 7 in position on said shaft 1, all substantially as described.

Signed by me at Fort Wayne, Allen county, State of Indiana, this 11th day of March, A. D. 1895.

JOHN DENNISON.
