JOHN HANSEN, OF BETTENDORF, OTWA, ASSIGNOR TO DAVENPORT MANUFACTURING CO. INC., OF DAVENPORT, IOWA.

POWER BALING- MACHIN E.

Application led .Tune 15, 1925. Serial No. 37,209.

To all whom t may concern:

Be it known that I, Jol-IN HANsnN, a citi- Zen of the United States, residing at Bettendorf, in the count)7 of Scott and State of Iowa, have invented certain new and useful Improvements in Power Ealing Machines, of which the following is a specification.

My invention has reference to power baling machines, and belongs tothat type vthereof wherein a platen or ram is arranged to be moved vertically by means of a pair of vertical screws and travellers thereon, such as is embodied in my former application for Letters Patent of the United States, iled April 20, 1925, Serial No. 211425.

One of the purposes of the present invention is to provide a machine of comparatively large construction, such as is employed in places where there is a considerable accumulation of paper and other material, and which is so arranged that the material may be fed into the same from an upper Hoor, if desired.

Another purpose of the invention is to provide a machine of the class mentioned wherein the platen is formed of two parts or leaves, independent of each other, which leaves are arranged to drop downwardly out of the Way when the baler is to be provided with material, so as to leave the upper end of the baler entirely clear for the reception of such material. Y

Another object thereof is to provide a means for holding the platen parts in closed position while the baling operation is being carried on, and which will fully resist the compression force of such operation.

The particular construction, arrangement, and operation of the various parts of the machine will more fully appear from the following specification, reference being had to the accompanying drawings, wherein Fig. lis a side elevation of the invention, partly in section, the true proportions not being maintained therein, the length of the machine being somewhat contracted.

Fig. 2 is a plan view thereof, partly in section on the broken line 2-2 of Fig. l.

Fig. 3 is a cross-section on the broken line 3-3 of Fig. 2.

Fig. 4 is an end view of the platen control devices, with the platen sections inopen position.

Fig. 5 is a detail of the platen and supporting frame therefor.

Fig. 6 is an end view of the platen frame and parts supported thereby.

Fig. 7 is a plan view of the platen guiding mechanism, with adjacent parts shown in horizontal section.

Referring first to Fig. 1, the reference number 1 indicates the base of the machine, uponl which is supported a Hoor 2, provided with cross-channels 3 to receive the wires by which the completed bale is bound. `Upon base is supported a frame consisting of corner-posts 4, united near their upper ends by cross-pieces 5, and longitudinal plates 6. Fixed to the cross-pieces 5 are bearings 7, in which are rotatably supported the upper ends of a ends of said shafts being journaled in bearings 9 on cross-plates 10, on the base 1. Fixed on the lower ends of said shafts are volute gear-wheels 11, adapted for simultaneous operation from a common shaft, in Jthe manner shown in said former applicaion.

Interiorly threaded sleeves 12 are verticaily movable on the shafts 8, upon said shafts being rotated, and roclringly mounted on said sleeves are supports 18, with which a pair of plates 14 has a pivotal connection. Secured between said plates is a frame 15, having side plates 16. The structure so far described is largely similar to that set forth in said former application.

Supported from the side plates 16 is a platen or compression member, formed of two sections, each consisting of a plurality of plates 17, the plates of each section being capable of swinging downwardly and outwardly by means of a hinged connection of the central ones of said plates with plates 17a fixed to the plates 16. The plates 17 are preferably formed of pieces 0f wood of suitable thickness, and are separated by spaces 18, coinciding in position with the channels 8. The inner ends of the plates of the two sections are also spaced, and near said inner ends the plates of each section are united by a cross-plate 19, so that each of said sections willl act as a unitary member.

Fixed to the plates 17 at one end of the platen is a. pair of arms 21, at the upper ends of which are rollers 22, which bear against angle-plates 23, supported vertically in the machine by means of posts 4, consaid pair of screw-shafts 8, the lower Y nected with the main frame. Said arms and rollers serve to hold the platen sections in a horizontal position during the greater part of the movement of such platen. At their upper ends the tracks formed by the plates 23 are bent inwardly as at 25y in Fig. 3, which tracks are followed by the rollers 22, this movement being impelled by the weight of the platen sections, which drop d ownwardly at the side of the machine,l as shown in Fig. 4l; rlhis forms an opening through which the material may be fed downwardly into the receptacle of the machine, the upper part of which will be a little below the lower ends of the platen sections 17 when the platen frame is its highest point. Then the receptacle is filled the screws 8 are operated to move the platen frame downwardly again, the rollers 22 moving outwardly along the tracks 2a and bringing the platen sections'into a horizontal position again, in which position the work of compressing the material in the receptacle is performed thereby. The upward movement of the platen sections is limited by stops 26 on the inner faces of the end frames 15, with which the ends of the plates 19 contact. (Fig. 2.)

So far as the receptacle is set forth in the drawings herein, one end thereof is show n formed of plates 2T, spaced apart at their inner edges, and having said edges reinforced by angle-plates 28, which serve as guides for the arm 14tat that end of the machine. The outer edges of the plates 28 are secured to angle-plates 29, fixed in the frame of the machine. The opposite end of the enclosure is formed of a pair of plates 30, also spaced apart and reinforced by angle-plates 31, forming guides for the arm 14 at that end of the machine. By means of said guides and the pivotal support of the arms 14 the platen frame is permitted a limited freedom of movement in its vertical operations. The plates 30 are projected upwardly for a distance above the angle-plates 6, as shown in Fig. 3, soas to furnish supports for the tracks 25. During the compression operation the rollers 22 move freely along the tracks, the

compression stress being received entirely by the platen sections and frame which supports them.

The machine is simple and effective in operation, and the sections of the platen open and close promptly. Adaptations may be made to tit both ends of the platen with the operating devices, if desired, but this is not necessary.

lVhat I claim, and desire to secure by Letters Patent, is:
