BALlNG-PRESS.

fiPECIFICATION forming part of Letters Patent No. 335,290, dated February 2,1886.

Application filed June 25, 1885.

lower successively compresses the charges against the yielding end of the forming bale; and the principal objects of my invention are to provide an improved frame whereby iron may advantageously be largely used in its construction; to provide a simple, compact, and effective mechanism for actuating the follower; the simplification of the mechanism for decreasing the angular velocity and increasing the propelling force from the initial driving-wheel to the crank-shaft; to provide the condenser with a larger reciprocating movement than the follower; to apply during the upward stroke of the feeder the energy necessary to operate it and afford means of retaining the feeder near the top of its stroke while the press is in operation; to provide means for holding the baling-wiresin position for tying; to afford improved means for adjustmg the resistanceto the longitudinal movement of the bales; to provide an inclined hopper and condenser for facilitating the work incident to feeding the press; to afford facilities for readily stopping and starting the press. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top view of the press, wlth a port-ion of the platform and condensing-chamber flange broken away; Fig. 2, a side elevation of the same; Fig. 3, a vertical section of the machine on the line 1 2, Fig. 1. Fig. 4is a perspective View of the follower; Fig. 5, a vertical section of a modified form of the same; Fig. 6, a vertical section of the press on the line 8 4, Fig. 1; Fig. 7, a horizontal sectionof the same on the line 5 6, Fig. 2; Fig. 8, a vertical section of the baling-chamber on the line 7 8, Fig. 7 Fig. 9, a vertical section of a modified form of the reciprocating mechanism. Fig. 10 is an enlarged view of a portion of Fig. 3.

Serial No. 169,791. (No model.)

Similar letters refer to similar parts throughout the several views.

The main frame, whichis made of iron, consists of the sides a a and arms I) b. The arm b, which is securely bolted to the sides, as shown in Figs. 2 and 8, forms the bottom of the baling-chamberand acts as a flexion-beam to support such portions of the machine as lie between the skids e z. The arm I), which is bolted to the upper flanges of the sides a a, forms the top of the bale-chamber, and, acting as a girder, supports the superstructure. Both arms project beyond the ends of sides aa, and are provided with flanges I) at their edges, which strengthen them and form guides for the bales.

The vertical sides a a, which form the walls of the portion of the baling-chambcr inwhich the follower operates, and in which the successive charges are compressed, are provided with bearings for the crankshaft 0, countershaft (Z, and ways or guides m for the follower, also with flanges or ribs at their upper and lower edges, to which the arms I) b are securely attached by bolts passing through said arms and flanges, asshownin Fig. 8. Instead of these flanges, lugs cast 011 the sides might serve thesame purpose. On the end ofcrankshaftc the pinion c and balance-wheel ,which is also the initial driving-wheel, are so hung that they may turn freely on said shaft.

The hubs of the driving wheel and pinion are provided with a claw-clutch, which can be thrown in and out of operation by the longitudinal movement of the pinion toward or from the driving-wheel. For operating this clutch the pinion c is connected in the usual manner with lever f, which is bent at its upper end, so as to be conveniently operated from either side of the press. Gear d and pinion d are rigidly attached to the ends of counter-shaft d, and are adapted to mesh into pinion c and gear 0*, respectively. The latter gear is rigidly attached to the crank-shaft. The angular velocity and propelling force of the crankshaft are, respectively, decreased and increased to the required amount by transmitting the power from the drivingwheel to the crankshaft through the simple mechanism consisting of the counter-shaft and four gears above named.

Aside from the constructive advantages of hanging the driving-wheel g and pinion c loosely on the crank-shaft, the efficiency of the press is thereby increased, since the driving-wheel and pinion revolve in thesame direction as the crank-shaft, therefore the loss by friction at this point, being proportional to the difference of their angular Velocities, is

thus reduced.

The crank-shaft 0 consists of two parts connected by the double crank e, on the crankpin of which is hung the anti-friction wheel m, whose diameter is large enough to include the whole of the crank within its periphery.

The follower n, which is delineated in Fig. 4, is constructed by securely bolting the ends to the sides. The ends are provided on their inner sides with tracks a n for the wheelnn. These tracks, as shown in Figs. 3 and 4., are plane and parallel surfaces, whose distance apart is equal to, or a little greater than, the diameter of the wheel at. The openings in the sides of the follower, through which the shaft 0 passes, are sufficiently large to allow the followerto reciprocatewithout interfering with the shaft. The follower is restrained from all but longitudinal motion by guides m, which are apart ofor attached to sides a a. The wheel 'm,which is hung so that it may turn freely on the crank-pin e, and is carried by the crank in a circular course, rolls on the tracks n n, successively, and thus imparts a reciprocating motion to the follower.

The condenser h, which is adapted to re ciprocatein the inclined condensing-ehamber, is connected by rods h to the upper end of lever Z, which is connected at a point nearer its fulcrum to the follower a by the connecting rod 1), and is hinged at its lower end to the cross-bar Z. The motion of the follower in being transmitted to the condenser through the lever Z is increased by said lever, so that the condenser has a longer stroke than the follower. The feeder 0 is hung to the arm o,which is hung in the hangers 0", supported by cross-bar q. Said cross-bar is supported by posts-q and braces g*, which are securely at tached to the main frame. The feeder is operated by cam 1', which is rigidly attached to shaft 0', which is hung in hangers supported by braces (f. The cam is driven by link belt r which runs on equal sprocketwheels rigidly attached to the ends of shaft-s c and r, respectively. The cam r acts upon rollers 1", pivoted to the feeder-arm 0, and is set so that it raises the feeder during the backward stroke of the follower. Spring 0 which is attached to the under side of the bar q, acts upon the upper side of the feederarm, thus accelerating its downward stroke. The spring 0 relieves the feeder from any jar at the bottom of its stroke, by coming in contact with the bottom of the slotin the head of the condensing-chamber. lVeight 0 is added to the arm 0 to increase the force of the downward stroke to the required amount.

Levers s s, Fig. 6, which are pivoted to the .in the usual manner by the retainers x. suitable intervals follower-boards c, for sepa' condensing-chamber head, are connected at equal distances above and below their fulcrums by straps s, so that a movement of one will impart an opposite movement to the other.

Said levers are bent outward at their upper ends and provided with handles, so as to be conveniently operated from either side of the press. When they are thrown toward each other they form a support for the feeder, thus preventing its operating. \Nhen thrown outward they allow it to fall and operate again. An inclined hopper, t, for receiving the hay. preparatory to being fed into the condensingchamber, is provided just above and back of said chamber. The hay, while being fed in front of the condenser, is prevented from falling back of the same by the shield h, attached to the condenser. Rollers it, provided with grooves 14. a a, corresponding in position with grooves in the follower-boards o, are hung on stay-bolts which connect the arms I) b near their middle. As the follower-boards pass the rollers u, the baling-wires that have been passed through the grooves in them are received by grooves u u u, and as the bale is forced along the bale-chamber the wires are held in the position shown in Fig. 2 by said grooves. The grooved rollers thus facilitate the work of tying off the bales. The wings w, which are hung on the stay-bolts which connect the ends of the arms I) b, are connected at their ends by the threaded bolts w, by which they can be adjusted, so that the surfaces they present to the bale will be more or less inclined to each other, thus causing more or less resistance, as may be required,

. to the longitudinal movement of the bale. When thepress is not in operation, as a coni veuience in storing away, these wings may be ;turned backward against the arms I) I), thus redi'lcing the length of the press. The dotted .lines in Fig. 3 show the position of the follower, condenser, and feeder. at the outer'end of their stroke.

In operation, thematerial to be pressed is first thrown upon the hopper it, from which, whenthe condenser has nearly reached the back end of its stroke, it 'is fed down the sloping trough and into the condensing-chamber, where itis pressed during the advanced stroke IIO IIS

of. the condenser, at the completion of which the feeder drops and transfers the partiallycompressed charge to the baling chamber. The feeder remains at the bottom of its stroke and forms the top of the baling-chamber, while" the follower compresses the charge against the forming bale. When relieved by the follower the charges are held in position At rating the bales, are placed in the baling-chamber. During this operation the feederniay be retained at the top of its stroke by levers 8, thus avoiding all danger to the operator. The bales are tied and delivered inv the usual manner.

It may be observed that the power necessary to operate perpetual presses varies with the position of the crank, the most power being required during the forward stroke of the follower, noticeably near the end. In my press the parts are adjusted and connected so as to diminish this variation, to wit: The work for operating the condenser (while compressing) and the feeder is done during the backward stroke of the follower, and, further, the extra work imposed upon the condenser by its long stroke correspondingly diminishes the work that remains for the follower to do during its forward stroke.

Among the modifications to which some of the parts of my press are susceptible, I would mention the following: \Vhile the diameter of wheel at is such that the periphery of the wheel barely includes the crank, it may be either larger or smaller. The latter change, however, necessitates tracks for wheel m, constructed so as to pass between the crank-arms and not interfere with the motion of the follower. Such tracks are shown in Fig. 9. In the place of an anttfriction wheel hung directly on the crank-pin, two or more such wheels may be hung on a head, which is hung 011 the cranlspin, as shown in Fig. 9, while, as above described, the tracks a are plane parallel surfaces, they may be curved in the plane of the wheel m. Fig. 5 illustrates a set of curved tracks, whereby the force exerted by the crank against the follower during the forward end of its stroke may be much increased. This modification still further equalizes the power necessary to operate the press during a revolution of the crank. Instead of straight guides in, the follower may be paired with curved guides, or, what is equivalent, be hung so as to rock about a distant axis. The movement of the pinion c, for throwing the press in and out of operation, may be restrained, and the driving-wheel g afforded a corresponding movement and be connected with lever f for the same purpose. The skids z :4 may be replaced by axles, and the whole mounted on wheels and made portable.
