BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 325,843, dated September 8, 1885.

To all whom it may concern:

Be it known that I, LEvI B. LATHROP, of

Hollister, county of San Benito, and State of 1 7 No. 225,396, dated March 9, 1880, and No.

249,640, dated November 15, 1881.

Myinvention consists in details of construction, as hereinafter described, and specifically claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of my balingpress. Fig. 2 is a vertical cross section through thebaling chamber, showing the strips for finishing the ends of the bale. Fig. 3 is a detail section showing the latch mechanism of the end door. Fig. 4 is a horizontal section of the latch-shaft. Fig. 5 is a longi-' tudinal vertical section of my press, showing the follower driven home. Fig. 6 is a similar View of the follower withdrawn to its limit. Fig. 7 is a perspective view of the rear end of the toggle, showing the equalizer-bar. Fig. 8 is an elevation of the double conical chainpulley. Fig. 9 is an elevation, showing the application of the brake mechanism. Fig. 10 is a perspective detail of the brake mechanism.

A is the body of the press, mounted on wheels B. The forward end of the press, as shown in Figs. 5 and 6, constitutes the balingchamber and is designated by 0. Back of the baling-chamber is what may be called the feedchamber D, to which access is had through the top door, d. Within the press is the follower E, adapted to move back an forth for the usual purpose.

F are strips or bars (shown in Fig. 2) within the press. These are set edgewise and are properly secured to the bottom and the top of the press. They are parallel to each other and are separated by a short space. The object of these strips is to finish the ends of the the hay is fed in through the topin great quantities, as there is no opportunity to tramp, some means must be provided for automatically folding in the ends of the bale, so that they shall not be ragged and rough. This is the function of the strips F. They bend or fold the hay which is pressed down between them and over them, and when the bale is ejected the ends are smooth, and theropes hold them properly;

G is the toggle, the short arm of which is pivoted at g to the, rear portion of the pressframe. The long arm of this toggle is a forked one, as shown in Figs. 5 and 6, and its forward end is framed solidly in the follower. As shown in my former Letters Patent, the toggle was pivoted to the back of the follower-in the first patent being pivoted toits position of the latter, as shown in Fig. 6. This renders it necessary to mount the fol-- lower upon a roller or rollers located at its bottom, whereby it may easily tip, and may also move back and forth with little friction;

may be a number of these across the width or the follower. It will be observed that" this roller is located at the forward edge of the follower. This position isnecessary, for the purpose ofkeeping the lower forward edge of In Fig. 6, e is one of the rollers, and there This rigid at-..

the follower as near to the lower surface of the press as possible and to make it move true. If it were placed at the back edge, it would have a tendency to throw the forward edge up and allow it to ride over a portion of the hay, but being on the forward edge it fulcrums on said edge, thereby keeping it down close to its bearing.

Across the top of the rear portion of the frame is the shaft H, upon which is mounted the main operatingwheel I,which is intended to carry a rope, to which the horses are attached, for the purpose of rotating said wheel and shaft.

Upon the shaft, as shown in Fig. 8, is a double conical pulley, J. This pulley has a central deepgrooved face, j, and side conical grooved faces, j. Upon the central grooved face, j. is secured and adapted to wind a chain, K, Figs. 5 and 6, the forward end of which is. attached to the back of the follower.

Secured to the side conical faces, j, are the chains L,=the rear ends of which are seen in Fig. 7. Through the rear end of the toggle G is passed a shaft, 9, which forms the pivotjoint of the arms of the toggle. Upon the center of this shaft is journaled or pivoted a link, M, in the reir end of which is pivoted the equalizerbar N, to the ends of which the chains L are attached.

I prefer to make the shaft 5 and the link M integral by forming the shaft as pins projecting from the sides of the link and journaled in the arms of the toggle.

The general operation of the machine is similar to that shown in my previous-patents, and need be but briefly described.

By rotating the wheel I the chains L are wound up, thereby raising and moving forwardthe toggle G, by which the follower E is driven home. When the strain on the wheel I isrelieved, the weight of the toggle causes it todrop down, thereby returning the follower. The equalizer N keeps the chains even and distributes the strain equally between them, and by being pivoted in the toggle by means of the link said equalizer conforms to the motion of the toggle, and thereby remains at the same angle.

' In my second Letters Patent I show as the equivalent of the chain K a strap, which is provided with blocks, and which winds up on a pulley on the dri-vingshaft. The object of this strap, as therein explained, is to take.

advantage of the momentum of the large wheel I, which is acquired by reasonof the dropping of the toggle, to cause said wheel to pull the follower farther back than the toggle itself would. The belt acts as a connection between said wheel and the follower, andin order to make use of this connection and prevent any slacking of the belt, I have blocks upon it which practically increase the diameter of the pulley over which it winds and thus keep it taut. The chain K in the present press is for precisely the same pur- Q press.

pose; but instead of having the blocks, which are rather clumsy, I have in this case the deep-groove-faced center j of the pulley J. The chain K, in first winding around said face, is taken up sufficiently for the incipient momentum of the wheel, and as this momentum increases the chain winding upon itself in the facej winds up faster in accordance with the revolution of the wheel, as it practically increases the diameter of the face on which it winds; but even this momentum is not sufficient to draw the follower back as far as I desire. Accordingly I have the follow ing mechanism: (Shown in Figs. 5 and 6.)

Mounted transversely on the extreme rear of the press is a shaft, 0, around which is coiled a heavy spiral spring. 0. Upon this shaft is secured a crankarm, P, to the upper end of which is attached a bar, 29, the lower end of which is connected with the lower portion of the short arm of the toggle by achain, p, as shown in Fig. 7.

Upon the inner surface of the bar p is a guide iron, p

The operation of this device is as follows: Assuming the follower to be moving back from the position shown in Fig. 5 to the position shown in Fig. 6, the spring 0 causes the crank-arm P to rise and the harp to move back, keeping its connection with the toggle taut. The momentum of the toggle would barely carry its short arm past the perpendicular,which would not be sufficient to move the follower back as far as desired, but as it swings to and just past theperpendicular, the spring 0, through the crank-arm P and arm p, pulls it back farther to a position shown in Fig. 6. that by coming in contact with the shaft 0, it will throw the bar 1) out far enough to prevent a line strain upon it when the toggle is raised again, and thus produces more of a circular motion, whereby it can be drawn down.

In order to hold the follower in thcposition shown in Fig. (3, I have the weight Q. This is suspended from an angle-arm, (1, attached to the back of the follower. It is provided with a roller, (1, as shown. When the follower is in the position shown in Fig. 5, the weight simply travels on the bottom of the feed-chamber D, but when the follower is brought back, as shown in Fig. 6, it drops down over the end of the bottom of the press and locks the follower,preventingit from moving forward again byreason of the tendency of the toggle to swing down.

A, Figs. 1 and 8, is the end door, through which the bale is discharged. The catch or latch of this door is as follows: Bolted to the outer surface of thedoor are straps a, having on their endsthe beveled catches a.

"It is a shaft, journaled in the ends of springarms r, which are bolted to the side of the Theshaft is provided with a handle,

1', as shown in Fig. 1, and is also provided IOC The object of the guide-iron p" is near its top and bottom with beveled catches r", as shown in Fig. 4. p i 7 When the door A is slammed to, its catches a, meeting with the catches 1", force the shaft outwardly on its springs and partially turn it until the catches engage.

To open the door, the handle 1" is turned forward, thereby forcing the engaging surfaces of the catches against each other-,whereby the shaft is thrown outwardly on its springarms, at the same time its catches r pushing the catches a away, and thus freeing the door.

S in Fig. 1 is the hay-platform. T is a supplementary platform, located on the side of the press and below the hay-platform. This is for the purpose of allowing a man to stand in a convenient position for forking the hay in through the top door of the press.

In order to stop or check the momentum of the driving-wheel I as the follower comes back, I have a brake mechanism. (Shown in Figs. 9 and 10.) Upon the rear portion of the toggle is bolted a hook, U, which engages with a crank-arm, c.

crank-arm 22 up and puts on the brake-le-.
