Specification of Letters Patent.

Application filed February 2, 1912. Serial No. 675,034.

To all whom it may concern:

Be it known that I, GOTTFRIED WVELGER, manufacturer, subject of the Kingdom of Prussia, Empire of Germany, residing at Seehausen, district of Wanzleben, Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

My invention relates to improvements in baling presses for compressing loose and bulky material, such as chad, straw, hay, flax straw, and the like, which compressing is desirable, for example, for transporta tion.

The object of the improvements is to provide a press of this class in which the material is more uniformly distributed over its cross-sectional area than could be done in presses heretofore constructed, and with this object in view my invention consists in providing means for uniformly distributing the material to be baled over the cross sectional area of the pressprior to compressin the same.

While my invention is particularly useful in combination with baling presses wherein the presser chambers are disposed horizontally or substantially horizontally, I wish it to be understood, that my invention is not limited to such use.

In order that my invention be more clearly understood, several structural embodiments thereof have been shown in the accompanying drawings in which the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawings Figure 1 is a diagrammatical view of a baling press illustrating the invention, Fig. 2, is a side view of a baling press equipped with my improved apparatus for distributing the material to be baled prior to compressing the same,

Fig. 3, is a similar side view showing a modification of the apparatus for distrib uting thematerial, Fig. 4, is a similar side view of the press illustrated in Fig. 3 and showing the distributing member in a dif fer-ent position, Figs. 5 6, are side views of a further modification of my improved apparatus, the operative parts being shown in both figures in different positions, and Fig. 7, is a detail view showing a modification of the apparatus in which the distributing member is adjustable.

In baling presses wherein the presser chambers are disposed horizontally or substantially horizontally it has heretofore been found diificult if not impossible to compress the materials into bales of sufliciently uniform density, because the material which is supplied into the pressing chamber from above is piled up on the bottom to form a flat pile. Particularly where short fiber material is to be baled, the pile is forced forward by the pressing plunger and forced against the compressed material at the bottom thereof. Therefore the bales are considerably more dense near their bottoms than at their tops, and they cannot well be bound and are liable to fall apart again after leaving the press.

The object of the improvements is to provide means in combination with baling presses whereby bales of sufficiently uniform density are produced. With this object in view my invention consists in providing means in the baling press whereby the material is prevented from spreading on the bottom of the press and the portions of the material which are near the bottom are in part raised up again to the top of the press.

In order that the invention may be clearly understood, I have shown in Fig. l a diagram illustrating the preferred method of lifting the material, which method is particularly designed for use in a baling press of the aforementioned type. As is shown in the said figure, within a horizontal or substantially horizontal chamber or channel a plunger 11 is mounted for reciprocation, by means of which the material is compressed into a bale 12. The material is supplied through an opening 13 provided in the top wall of the chamber 10, and when thus supplied it is liable to spread on the bottom of the chamber in the form of a fiat pile 17. To prevent this a holding member 14 is passed into the frame 10 through the opening 13, which holding member consists,

for example of a rack, a foraminated plate, an imperforate plate, or the like, and which can be rocked about a stationary or movable axis 15. The operating mechanism for the rack 14 is connected with the operating mechanism of the plunger 11, and it is moved thereby in such a way, that upon the return stroke of the plunger it assumes a more or less upright position with its end extending downward into the chamber 10 and permits the material to fall into the movable part of the press.

chamber. Upon the forward or compressing stroke of the plunger the rack is rocked upward. Thereby the portion 16 of the material which in the figure is marked with hatchings is lifted upward and in front of the upper portion of the previously compressed material, that is into the position marked with crossing hatchings, where the material is compressed by the plunger 11 is equipped with my improved apparatus.

A press of the construction sliown, but without the rack, has heretofore been used for compressing hay, straw, and the like. As shown in the said figure, above the chamber 10 of the press a plate, sieve, or rackl-i is so mounted on a stationary rock shaft 15, that it is rocked by its weight or by spring action into the upright position shown in full lines when the plunger 11 is moving backward and away from the bale 12. When in this position the rack 14 does not interfere with the filling of the chamber, so that the material can fill the space provided between the rack 14: and the front face 18 of the compressed bale 12. Upon its compressing stroke the plunger 11 engages the rack 14: with its upper edge 19 and rocks the same upward and into the position shown in dotted lines, and in this movement the lower edge 20 of the rack describes the curved path w. The major portion of the material piled up on the bottom of the frame is thus lifted upward, and while the edge of the rack approaches the upper part of the press the said material is spread over the front side of the bale, sot-hat the plunger 11 which immediately follows the edge 20 is enabled to compress the material which has thus been brought in front of the upper part of the bale. When the plunger is moving backward the same operation is repeated.

Instead of operating the rack directly from the plunger I may also operate the same through the intermediary of a gearing connected with the plunger or with another If desired the rack may be jointed to the plunger itself,

' and in this case it may be rocked either by stationary stops or by links which are jointed to a point of the rack located away from its pivot.

In cases where the press is designed for baling different materials which drop from the rack more or less slowly, I prefer to have the rack adjustable toward and away from the bottom of the chamber and the front face of the bale. This may be done in different ways. To show what may be done I have illustrated in Fig. 7 a construction in which the rack is adapted to be adjusted together with its pivot which for this purpose is mounted on a slide block 21 adapted to be vertically adjusted within a slotted bracket 22 mounted on the frame of the press. Or the construction may be such, that the rack is longitudinally shifted relatively to its pivot. The invention may also be embodied in presses of a difierent construction, or in presses which are used for baling other fibrous materials. I

Instead of mounting the rack for rocking movement on a rock shaft, I may guide the same along a rectilinear path, or I may combine rocking movement with movement along a rectilinear path.

My improved apparatus is the more effective, the more nearly the path of the outer edge of the rack approaches the vertical line.

In Figs. 3 to 6 I have shown several modifications in which the path of the edge follows more closely the vertical line, than in the form shown in Fig. 2, and in which, notwithstanding this, the said rack is pivoted above the path of the plunger and its lower edge is disposed near the bottom of the chamber when in its retracted position. For this purpose the axis of the rack is made shiftable, and it is so connected with the plunger or its driving gear, that it is shifted backward and in a direction opposite to the stroke of the plunger when the latter performs its compression stroke. Thereby the path of the edge of the rack is made more steep when it is being rocked about its pivot, and the said path substantially follows the front face of the compressed bale.

In the form shown in Figs. 3 and 4 the pivot 25 of the rack 26 is mounted on a rocking lever 27 the fulcrum 28 of which is located intermediate the ends of the lever on a relatively fixed part, for example on the frame 29. To the said lever a spring 30 is connected which tends to pull the same into the position shown in Fig. 3. The free arm of the lever 27 extends into the path of a stop 31 which is movable together with the plunger 32 and is adapted to carry along the lever into the position shown in Fig. 4f when'the plunger performs its compression stroke. When now the rack 26 is rocked upward by the plunger, and its pivot is shifted to the left by being mounted on the lever 27, the lower edge 33 follows the path at which is very steep as compared to the path m followed by the rack edge 20 of the example shown in Fig. 2. In order to make the movement of the rack more easy and to avoid wear of the parts the plunger 32 is preferably provided with one or more rollers 34 for guiding the rack 26.

In the form shown in Figs. 5 and 6 the fulcrum 40 of the lever 41 which carries the pivot 42 of the rack 43 is located below the frame 44, and at one end of the lever, while it is connected by means of a link 45 at a point intermediate its ends with a rocking lever 46 mounted on a pivot.47. The lever 46 is rocked by the plunger stops 48 cooperating with a spring 49, and the mechanism connecting the plunger and the lever is constructed substantially in the same way as the corresponding parts of the form shown in Figs. 3 and 4. The rack 43 bears against one or more guide rollers 51 which are mounted in stationary bearings 52, and it engages the said rollers through the intermediary of a cam piece 53 secured to the rack. It will readily be understood, that the said cam piece serves to shift the rack with its edge 50 toward and away from the front face of the bale, while the rack is being rocked; As compared to the form shown in Figs. 3 and 4 the form shown in Figs. 5 and 6 possesses the advantage, that by properly shaping the cam piece 53 a vertical and rectilinear path can be imparted to the outer end of the rack, wherebythe effect of the apparatus is considerably improved. The shape of the cam 53 can easily be determined by experiment. The other parts, for example the plunger 55 and its driving .gear may be constructed in the usual manner.

If it is desired to have the outer end 50 of the rack 43 adjustable toward and away from the front face, for the reason ex plained with reference, to Fig. 7, the bearing 54 for the pivot 42 and the cam piece 53 may be adjusted longitudinally of the rack 43, as has been indicated by additional screw holes 56 provided in the rack 43.
