Patented May 15, 1906.

Application filed July 2, 1903. Serial No. 16 L059.

To all whom it ntay concern:

Be it known that I, CLEMENS A. STRUVE, a citizen of the United States, residing at Fayetteville, in the county of Fayette and State of Texas, have invented certain new and useful Improvements in Baling-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in baling-presses.

The object of the invention is to provide means whereby the plunger is returned. to its normal position without providing a spring assembled therewith for this purpose.

Another object of the invention is the construction of a press provided with a sweep for actuating the plunger, and said sweep carrying improved bearings, as is hereinafter fully described.

Still another object of the invention is the production of a press carrying means for turning or pressing the edges of the bale being formed within the box, and said means simultaneously actuated with the other mechanism of said press.

With these objects and others in view the invention consists in a press provided with a suitable frame and a plunger mounted thereon, said plunger actuated by means of a sweep comprising a tongue and a bar extending at right angles thereto, said bar provided with rectangular bearings pivotally secured thereto.

The invention further consists in the mounting upon the frame of the press of a lever simultaneously' actuated by the sweep for returning the plunger to itsnormal position when the said press is in operation.

The invention further consists in the providing of a tucker or packing means which is simultaneously actuated by the plunger and the sweep and which is adapted to turn in or compress the loose edges of the bale as it is formed within the box.

The invention further consists in the novel construction and arrangement of parts, as is hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appende In the drawings, Figure 1 is a top plan view of the press constructed in conformance with my invention, and Fig. 2 is a longitudinal side elevation of the same. Fig. 3 is afragmentary plan view of a modified form of the invention. Fig. 4 is a fragmentary perspective view of the press. Fig. 5 is an enlarged detail view of the tucker mechanism.

Like numerals of reference designate corresponding parts throughout all the figures of the drawings.

In the drawings, reference-numeral 1 indicates a suitable frame upon which is mounted a box 2 and a plunger 4, which is provided with a head 5, having an angular extension 6 formed integral therewith. Mounted upon a rigid bracket or bar 7 is a sweep 8, comprising a tongue 9, rigidly secured by suitable means to a bar or member 10, which is pivotally mounted at 11 to the said bracket or bar 7. Rotatively mounted by suitable means, as at 12, are rectangular bearings 13.

Blocks 14 are retained upon the frame 1 and provide in conjunction with the cross-bar 15 means for retaining the plunger 4 in an assembled position with the other mechanism of the press.

Pivotally secured to the frame 1 and adjacent to the plunger is a guide, which comprises in its construction a pivoted bracket or block 16, provided with a flat head portion 17 and a lug or extension 18, formed integral with the said block 16, projecting at right angles to the said portion 17. block, as heretofore stated, is pivotally secured to the frame and is adapted to be simultaneously actuated by the plunger 4, and the head or flat portion 17 is adapted to coact in a horizontal position with the like portion 19 of the plunger 4 when the said plunger is at its farthest position on an inward stroke. Secured to the said bracket or block 16 is a curved arm 20. Mounted upon the plunger 4 is a pin or bearing 21, which is adapted to engage the arm 20 of the block 16 and return said block to its normal position after the said plunger has been returned to its outward position. Pivotally mounted upon theframe 1 is a lever 22, provided with a series of apertures 23. The said lever 22 is provided with a right-angular shoulder 24, or, if it is desired, the shoulder may be formed with a detachable plate and rigidly secured to the lever 22. The rod 25, pivotally secured to the plunger 4 at 26, is adjustably mounted upon the lever 22, and this rod is adapted to be retained in an assembled position upon the said lever 22 The said and the plunger 4 by bolts or like means. When the press is in operation, the sweep is rotated, and as the bar comes in contact, by means of the rectangular bearings 13, with the angle-plate or shoulder 24 of the lever 22 the said lever 22 is moved into its outer position, and thereby actuating the rod 25. and withdrawing or extracting the plunger 4 from its inward or farthest position within the box 2. It will be seen by this construction I do not employ a spring or similar means and still provide a positive construction for actuating the )lunger 4. In so far as returning the said plunger to its outward position. As the sweep is moved the rectangular bearings, as aforesaid, will engage the lever 22 in the recess formed upon its angular shoulder 24 and passing beyond said shoulder will come into contact with the fiat surface 19 of the plunger 4, and as the pressure is continued upon the tongue 9 and the bar 10 the plunger will be forced inwardly, and when it is at its farthest inward position the flat surface 19 and the corresponding surface 17 of the bracket or block 16 will be in alinement, and as the rectangular bearing passes along the flat surface 19 of the plunger 4 it will come into contact with the surface 17 of the pivoted bracket or arm 16 and before the plunger 4 is permitted to return to its outer position by the actuation of the lever 22 the rectangular block will pass upon the flat surface 17 of the bracket 16 and will be entirely removed from the path of the plunger 4, and as-the sweep is rotated the pivoted arm or bracket will permit of the rectangular bearing to pass over its head or surface 17 and the extension 18, and as the plunger 4 is returned by the mechanism heretofore described to its normal outward posi tion the bent arm will come into contact with the pin on the plunger, and the said bracket 16 will be forced into contact with the plunger 4 and retained there until the rectangular bearing comes in contact and moves the same out of the said position.

I have found by practical experience that in,all cylindrical or other bearings which are now on the market in passing over the head of the plunger the said bearings as they perform this function are adapted to be nearly forced out of the path of the said member when they are beyond the center of their pivotable point, and this will cause the forcing of the sweep or tongue forward, and a jar or shock is imparted to the horse or horses. A further defect is that the plunger will crush these bearings quickly when a force is placed upon the same, and to overcome this defect I have found that providing a bracket adjacent to the lowest or innermost movement of the head of said plunger this bracket will receive the rectangular bearing and will not ermit of the same to be rotated, but will prevent the plunger from returning to its outward position until the said bearing is entirely removed from the plane of the stroke of said plunger.

In the modification Fig. 3 a stationary bracket 27 is secured to the frame 1, and said bracket is adapted to receive the rectangular bearing 13 when the same has passed over the head of the plunger 4. In this modification the bracket 27 prevents the bearing from rotating when the same is partially'removed and in contact with the head of the plunger. As heretofore explained, the said bearing must be entirely removed by the actuation of the sweep before the plunger is permitted to slide into its outward position upon the ress. The cross-bar 15 is secured at one end to the fixed bracket 27 and extends diagonally across the plunger 4 and is secured to a cross-piece of the frame near the opposite end thereof. In this modification the sweep is intended to be rotated in a direction opposite the direction of rotation in the preferred form, as illustrated.

As shown in Figs. 1 and 2, a tucker or mechanism for forcing the, edge of the bale inwardly after each stroke of the plunger is employed. This mechanism is provided upon the said frame for the purpose of producing a bale not having ragged or loose -ma terlial extending beyond the width of said ba e.

The operation and construction of the tucker device are as follows:

An arm or plate 28, which conforms in shape to the feed-opening, is pivotally mounted upon the box 1 and is provided with an arm 29, extending outside of said box. The arm 29 is provided with a crank-arm 30. A slot 30 is formed in arm 30. Pivotally secured at 31 to the box of the press is a crank arm or lever 29 as shown in Fig. 2. Said lever 29 is provided with an extension extending at right angles to the main portion of the same and at its lowest extremity is pivotally secured to a rod 32. The lever 29 is provided with a pin 31, which is positioned within the slot 30 of the crank-arm 30. The rod 32 is secured to the plunger 4 at 33. The arm 29 is provided with an extension projecting at right angles therefrom, said extension engaging the slotted portion of crankarm 30. When the plunger is at its outward position, the approximately U-shaped arm 28 of the tucker mechanism is extending inwardly into the box 2. When the said plunger is forced into the box, the rod 32 moves the lever-arm 29 and through the medium of the pin 3 1 lifts the crank-arm 30, and thereby releases the tucker from engagement with the material which is being compressed within the box 2. It will be seen that by the construction of this lever-arm and the crank-arm of the tucker-bar there is permitted a slight independent movement of the different parts although the interlocking crank-arms are normally connected by means of the extension formed upon arm 29" engaging the slotted portion of arm 30; but before the plunger has reached its outer position the said leverarm will force the tucker down into the said box 2 of the press. This movement is simultaneous with the action of the plunger, and as the hay is pressed into the box 2 of the press the plunger will force the same into the bale upon its inward stroke.

The advantage in the construction of my invention lies in the fact that the mechanism for returning the plunger to its outward position prevents the same from being actuated. by the material which is adapted to be pressed within box 2. It may happen that a foreign object is placed within the box, and if a spring for returning the plunger were employed the said plunger would be. returned to an outward position before the mechanism of the press is in position for this operation. The rectangular bearings prevent the plunger from returning to an outward position before the said bearings are entirely moved from the path of the said plunger and insure the posi tive actuation of the device and also prevent the forcing of the sweep too quickly out of position, as is common with the ordinary bearings employed upon baling presses now in use.

The mechanism for forcing the material forformmg the bale without the usual ragged or loose condition, as heretofore experienced, is operated upon each actuation ofthe plunger, the material which is forced into the bale by the stroke, the edges of such material is turned into the portion of the bale and, as heretofore stated,insures acompact and even surface.

Although I have shown in the accompanying drawings and described in the specification the preferred forms of my invention, I reserve the right to make such modifications and changes in dimensions of the press as shall fairly fall within the scope of the invention.

Having thus fully described my invention, what I claim as news, and desire to secure by Letters Patent, is-
