BALlNG-PRESS.

SPECIFICATION forming' part of Letters Patent No. 754,493, dated March 15, 1904.

Application led April 15, 1903.

i T all whom, t may concern,.-

Be it known that I, THoMAs F. ORMOND, a

citizen of the United States, residing at Huntsville, lin the county of Madison and Stateof Alabama, have invented a new and useful Balpower; and it consists in the construction and combination of elements hereinafter fully described and claimed, and shown in the accompanying drawings, in which- Figure l is a plan view of the press and the horse power motor operatively connected therewith; Fig. 2 is a side view of the press alone, theview being taken from the side opposite to that on which the motor is located. Fig. 3 is an end view of the press and the preferred form of motor'. Fig. 4 is a side elevation of the preferred form of motor alone.

The various parts are indicated by similar reference characters throughout the above- 4 mentioned views.

In baling-presses of the type to which my invention relates dificulties have been heretofore experienced in doing away with sudden shocks and strains upon the pressing mechanism and in making the necessary draft of the horses uniform. For the most part in presses of this character the effort required of the animals used to operate the press varies 'from a minimum of almost nothing at the beginning of the stroke of the press to an effort approximating the maximum of which the draft-animals are capable toward the end of its stroke. 'Ihese constant variations in effort on the part of the draft-animals are not only vmore fatiguing to the animals, and consequently effective to reduce the output of the press with a given expenditure of power, but the rapid increase land decrease of strain upon the operating mechanisms tends to rack the press and in a short time to cause its operation to become defective.

In the form of press and operating mechanism hereinafter described I have endeavored to obviate all of the defects above mentioned,

Serial No. 152,782. (No model.)

scribed, I obviate completely any rapid variation in the strain upon the operating parts of the press and keep the draft effort required of the horses operating the horse-'power motor tolerably uniform.

Referring to the drawings by reference characters, 1 and 2 represent the baling-boxes of my improved press. These boxes are oppositely disposed, as shown, but slightly dis` alined, so that the longitudinal median line of each box would, if produced, pass outside of and at a little distance from one side of the other. The boxes are braced in this position by means of brace-rods 3 and 4, the former being parallel with the median longitudinal lines of the baling boxes and thelatter being arranged at an angle thereto, as shown.

5 and 6 are plungers which reciprocate in the boxes 1 and 2. The plunger 5 is pivotally connected to one end of a toggle composed of the members 7 and 8 and having its other end pivotally mounted in brackets 9 upon the side of the box 2. The member 8 of the toggle is braced by means of a truss-rod 10,. ex'- tending from a bracket 11 immediately above the bracket 9 to the joint 12, where the two members of the toggle are pivotally connected. The plunger 6 is provided with a similar toggle composed of the members 13 14, pivotally mounted at the end opposite the plunger in brackets 15, similar to the bracketsV 9 9, and a brace member 16, extending from a bracket 17. over the brackets 15 to the joint 95 18, at which the members 13 and 14E of the toggle are united, serves to brace --a second toggle in a manner similar to that employed on the first-mentioned toggle. lConnecting the joints 12 and 18 of theV two toggles is a IOC cross-bar 19 of such length that when the' members of one toggle are in alinement the members of the other are at the opposite extreme of their movement. Power is imparted ordinarily to the two toggles and through them to the plungers 5 and 6 by means of a horse-power motor, which is preferably of the form shown in the drawings, in`which 20, 21, and 21 are members forming a frame upon which the operating parts are supported.

22 is the main shaft of the horse-power supported in suitable bearings 23 24 and having rigidly secured thereon, near its lower end, a gear 25, which is in mesh with a pinion 26, half the diameter of the gear 25, which is carried by a shaft 27, upon which the pinion is rigidly mounted. The shaft 27 is shorter than the main shaft and is supported in bearings 28 29. Mounted upon the main shaft at a suitable height above the base of the motor is a power arm A, consisting of the cross member 30 and the two converging arms 31 32, rig'- idly fastened at the ends of the cross-arm 30 and bolted together at their opposite ends, as shown. The power-arm is braced by a trussrod 33, adjustably mounted on the main driving-shaft and bolted to the outer end of the power-arm. Rigidly secured to the shaft 27. below the pinion 26, is an arm B, similar in construction to the power-arm A, being composed of a cross-piece 34 and two converging members 35 36, fastened to the ends thereof. The arm B has pivotally connected to the outer end thereof a connecting-rod 37, which is also pivotally connected with the proximal end of the cross-bar 19, connecting the two toggles, and the arm B is of such length that the motion imparted through the connecting-rod 37 to the cross-bar 19 in a half-revolution of the shaft 27 will move the toggles from the position of alinement to the opposite extreme of their movement, or vice versa.

In the drawings I have shown only a single pair of baling-boxes and a horse-power motor to impart motion to the operating parts thereof; but I wish it to be understood that I may, if it is desirable, employ another pair of boxes arranged on the opposite side of the motor without modifying the structure thereof in any way, and if sufficient power be employed it would be possible by slight modification of the supporting-frame of the motor to provide for the simultaneous operation of four pairs of baling-presses arranged symmetrically around the motor. I wish it further understood that while I have shown a horse-power motor for driving my improved press I do not wish to be limited to the use of a motor of this kind, as the strains are rendered so nearly uniform in my improved press and the variation in said strain is so gradual that a steam-engine may be successfully employed in driving it.

By means of the arrangement of parts above described the compressing movement of one plunger is not only always synchronous with the releasing movement of the other plunger, but when the movement of the compressingplunger is slowest and the resistance greatest the withdrawal movement of the other plunger is most rapid. This relation in the movements of the two plungers is advantageous in facilitating the introduction of hay into one pressing-box before the pressing in the other box is entirely complete, and so permitting a more rapid action of the press as a whole.

Another advantage obtained by the combination of toggles and plungers with driving mechanism of the class described is that owing to the reactive efect upon one toggle of the elastic force of the compressed hay during the pressing operation being performed by the other toggle no springs are required to cushion the action of the plungers and a more positive and accurate motion is obtained.

The general advantage always obtained by using toggle-joints-namely, rapid movement of the operative parts when the strain thereon is least and slow movement when it is greatest'is of special value in machines of this class in relieving them from all shock or Jar.

Another advantage contemplated in the arrangement of the motor and press,as described and shown, is thatwhen the horses attached to the power-arm A cross the connecting-rod 37 they are making their minimum exertion. This result is brought about by having the diameters of the gear 25 and pinion 26 inthe ratio of two to one and arranging the arms A and B in the position shown in the drawings. In consequence of this arrangement the two toggles are in similar position when the horses cross the connecting-rod, and consequently the pressure upon the two plungers is most nearly balanced.

It will be observed that in the construction of my press the various parts have all been united by bolts in such a way that it is very easy to disassemble the various parts of the structure, and when it is desired to transport the press from one place to another all that is necessary is to disconnect the toggles from the brackets on the sides of the boxes, disconnect the connecting-bar from one of the toggles, push the plungers into their respective boxes after swinging the free ends of the toggles over the ends attached to the plungers, and mount each box upon wheels in any desired manner so that each may be separately hauled.

The operation of my`improved press is so clearly obvious from the drawings and foregoing description that no detailed account thereof is deemed necessary.

Having now fully described and pointed out the advantages of my improved press, what I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination in a baling-press, of a pair of baling-boxes oppositely disposed and slightly disalined, plungers movable in said IOO IOS

4. The combination in a baling-press, of a pair of boxes oppositely disposed and slightly disalined, plungers movable in said boxes, a pair of toggles each having one end secured to a plunger in one box and the other end secured to a side of the other box, said toggles being connected by a cross-bar to keep their joints at a constant distance apart, and means for applying power to said toggles, substan tially as described.

5. The combination in a baling-press, of a I pair of baling-,boxes oppositelyarranged and slightly disalined, plungers movable in said boxes, a pair of toggles, each of said toggles having one end pivotally secured to a plunger in one box and the other end pivotally mounted in a bracket on the side of the other box, a cross-bar connecting the joints of the two toggles to keep them a constant distance apart, a motor, and a connecting-rod pivotally connected with the cross-bar and a crank-armV on the motor, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto atxed my signature in the presence of two witnesses.
