Specification of Letters Patent.

Application filed April 24, 1916. Serial No. 93,289.

To all whom it may concern:

Be it known that I, NnLsoN B. HENRY, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Imrovements in Methods of Baling Fibrous Iaterials, of which the following is a specification.

My present invention relates'to improvements in the art of compressing hay or other fibrous materials and forming the same into bales, and it comprehends an improved method consisting in the performance of a series of steps in sequential order whereby the production of the bale is greatly expedited and facilitated.

Preferably, the sequential steps of each series or cycle of operations are performed concurrently, with the result that the yield by the method in bales is greatly increased.

The method of the present invention con- 7 sists generally in compressing an entire charge of material suificient for a bale to the desired extent by a single sustained thrust while opposite sides and an end ofthe charge are confined, then retaining the compressed charge under compression independently of the force which compresses the charge, then tying the compressed charge while so retained under compression to form the fin ished bale, and finally releasing the compression upon opposite sides and the end of the bale to permit ejection of the finished bale. Preferably, these sequential steps are performed concurrently. By retaining. the charge under compression independently of the force which compresses the charge, the tying of the charge is effected duringthe period of compression of the next succeeding charge or charges.

The method may be carried out with the aid of apparatus of various kinds, an example of such apparatus being shown in the accompanying drawing, wherein 1- Figure 1 is an elevation of a compress;

Fig. 2 is a top plan View of the same, and

Figs. 3 to 5, inclusive, are diagrammatic views showing the successive steps of compressing a charge, retaining the charge under compression independently of the compressing means, while the charge is being tied to form a bale, and releasing the compression upon opposite sides and an end of the finished bale.

Similar parts are represented by the same reference characters in the several views.

The apparatus shown will be first described and the method carried out by the said apparatus will then be described.

The apparatus shown comprises a suitable press frame embodying a base 1, a head 2, rigid tension rods 3 connecting the base and the head, and a compressing device shown in the present instance as a hydraulic ram 4. A plurality of press chambers or boxes 5 are provided wherein the charges of material are compressed, retained under compression ble about one of the tension rods of the press frame as an axis whereby the press chambers or boxes may be positioned successively in alinement with the ram or other compressing device. I

Each press chamber or box comprises relatively fixed side members 7 and 8, the memher 7 in the present instance being fixed to the carrier while the member 8 is hinged or pivoted thereto at or near its lower end. In this construction the side members are adapted to occupy a position in parallelism or substantially so during compression and while the charge is held under compression to permit tyingthereof, the side members being spread apart or relatively expanded laterally after the tying operation has been completed. That end of each press chamber which sustains the force of compression of the ram is also provided with a head 9 which is adapted to occupy a predetermined position while the charge is being compressed and while the charge is held under compression, and the head is adapted to move outwardly or in a direction endwise of the press chamber after the tying operation has been completed. Any suitable means may be provided for effecting relative lateral movements of the side members and the head of the press chamber. As shown, cranks 10 and 11 connect opposite sides of the head 9 with the tops or adjacent ends of the side members 7 and 8, the cranks when in one position locking the head in its inner position to sustain the compression of the charge while the side members 7 and 8 occupy their inner position, and when the cranks are swung upwardly the head 9 is moved upwardly and the side members 7 and 8 are expanded or spread apart laterally. Suitable means, such as a toggle 12, may serve to lock the side members in operative position while the charge is being compressed and while the charge is being held under compression. That end of each press chamber or box occupied by the compressed charge is provided with suitable means, such as dogs 13 and 1 1 which operate to retain the charge under compression after compression has been effected by the ram or compressing means. As shown, these dogs are adapted to swing into the press chamber to engage the lower end of the bale after compression thereof has been effected and to swing outwardly to clear the interior of the press chamber preparatory to the introduction of another charge therein.

According to the present invention, the operations necessary to the production of the bale are performed successively at different stations. For example, in Fig. 2 it represents the station where the press chamber receives its charge, B is the station where the charge is compressed, C and D represent the stations at which the tying of the bale is effected while compression thereof is maintained, and E represents the station at which the finished bale is ejected or removed. While the sequential steps just enumerated are performed at difi erent stations, these several steps are performed at thedifl'erent stations concurrently, rotation of the carrier step by step transferring the press chambers progressively to the different stations.

The method comprehended by the present invention consists in introducing a charge of material into the press chamber while at the station A, the side members and the head of the press chamber then occupying their contracted or closed position, compressing or transferring this press chamber to the compressing station B and there subjecting the charge vto compression by the ram 4: or equivalent compressing device, this compression being effected by a single stroke of said ram while the side members and the head of the press chamber are in closed or contracted relation, the compressed charge being maintained under compression by swinging inwardly the dogs 13 and 14, after which the ram or compressing device is withdrawn from the press chamber, transferring the press chamber successively to the tying stations, C and D, and placing the ties aroundthe bale while the same is maintained under compression by the dogs, and then transferring the compression chamber containing the tied bale to the ejecting station E and there unlocking and permitting lateral expansion or separation of the side members 7 and 8 and upward expansion of the head 9.

Fig. 3 shows the relation of the parts during the compression of the charge at the station E; Fig. t shows the position of the parts after the charge has been compressed, the charge being maintained under compression by the dogs and the ram or compressing device being withdrawn, and Fig. 5 shows the relation of the parts after the bale has been tied or finished and the side members and head expanded.

What I claim is 1. The herein described method of forming material into bales which comprises forming and confining a charge of material sufiicient for a bale and moving the same into compressing position, then exerting a single sustained compressive thrust on the entire charge while confined to compress the same to a reduced and predetermined size and to subject the char e to both longitudinal and transverse compression pressure, holding the charge to said predeten mined size and under said longitudinal and transverse compression pressure as developed by said thrust, removing the charge from the compressing position while thus held to said predetermined size and under longitudinal and transverse compression, and tyin the charge at said size and While thus held under both longitudinal and transverse compression.

2. The herein described method of forming material into bales which com rises forming and confining material su cient for a bale, then exerting a single sustained compressive thrust on the entire charge while confined to subject the same to both longitudinal and transverse compression pressure, holding the charge under said longitudinal and transverse compression pressure as developed by said thrust, then removing the medium which compressed the charge, and then applying ties around the charge while the charge is thus held under both longitudinal and transverse compression.

3. The herein described method of forming material into bales which comprises confining a charge of material suflicient for a bale, then applying a single sustained thrust to compress the entire confined charge, then holding the charge under compression both longitudinally and transversely, and removing the compression medium, then removing the charge from the compression position while the charge is thus held under longitudinal and transverse compression, and tying the charge while thus held under longitudinal and transverse compression.

4. The herein described method of forming material into bales which comprises forming a charge of material suificient for a bale, then applying a single sustained com- .pressive thrust to one end of said charge While the opposite end and all the sides of the charge are confined, removing the compressing medium from the charge and holding the charge at both ends and at its sides under the compression developed by said thrust, tying the charge while thus held under compression at both ends and sides, and then relieving the compression at the sides and at an end of the compressed tied bale.

5. The herein described method of forming material into bales which comprises confining a charge of material sufiicient for a bale and in one position of said confined charge exerting a single sustained compressive thrust thereon to reduce the same to a predetermined size, moving the charge while of said size and held under both longitudinal and transverse compression to another position, at such latter position tying the charge while of said size and held under longitudinal and transverse compression, and moving the tied bale into still another position and there relieving the compres sion on the same.

6. The herein described method of forming material into bales which comprises concurrently performing on a plurality of charges of materials the following operations sequential to a single charge, namely, at one station compressing a charge of material sufficient for a bale both longitudinally and transversely by a single sustained thrust and while the charge is confined, and holding the charge under such longitudinal and transverse compression independently of the force which efiected compression thereof, at another station applying ties around a charge while thus held under longitudinal and transverse compression,'at another station relieving the longitudinal and transverse compression on a charge thus compressed and tied, and at another station making up and confining a charge preparatory to compression at the first mentioned station.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
