BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 429,240, dated June 3, 1890.

Application filed June 5, 1889.

To all whom it may concern.-

Be it known that I, MANETHO C. JACKSON, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Baling Presses; and

I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereomwhich form a part of this specification.

My invention relates to anew and improved construction of horizontal pressesthat is, a press in which the plunger or baling head moves horizontally against the material to be compressed and formed into bales; and its objects are to furnish such a press of simple and economical, yet strong and durable, construction, adapted to produce a smooth, uniform bale, capable of speedy work, easily operated and managed, reliable and efficient; to which ends it consists in the features, constructions, and combinations more particularly hereinafter described and claimed.

In the drawings is illustrated an embodiment of the invention, Figure 1 thereof being a longitudinal section 011 the line a; 00 of Fig. 2, and Fig. 2 a vertical section on the line 3 y of Fig. 1.

In the figures the reference-numeral 1 indicates the framing-timbers, of any sufficient size and number, for receiving and supporting the operative parts of the press.

The baling-chamber is divided into two distinct compartments-n am ely, the compression-chamber 2 and the delivery-chamber A. The hopper is located above and opens into the compression chamber. Through this hopper the material to be operated upon passes into the press. Preferably the compressionchamber is formed with cast-iron sides 3, and within it works plunger-head 4, preferably made also of cast-iron and composed of ahead or front part with rearwardly extending flanges forming a box open at one end and upon the top. From its face projects inwardly one or more cars or lugs 5, to or in which is pivoted one end of a pitman-rod 6, for connecting the plunger-head to a prime Serial No. 313,155. (No model.)

motor. The sides 3 3 are curved or somewhat concaved from theinterior, as shown at 3 8, beyond which these sides are drawn inwardly, as shown at 9 9, making the exit of the compression-chamber somewhat narrower than the main body thereof. Pivoted retainers 10 are arranged upon the exterior of either side, the detent end thereof working through suit-able slots in the sides. They are pivoted on bolts 11 and have outwardly-projecting ends 12, to which are attached one end of springs 13, whose other ends are attached to framing-timbers, these springs acting to keep the retaining ends normally projected inwardly through the slots and in the path of the material acted upon, the detents having their edges lying inthe path of the material acted on, inclined or beveled that such material may readily force them out of its way.

As thus far described, as material is fed through the hopper 7 into the chamber 2, the plunger-head moves it forward and compresses it against whatever reacting surfaceas, for instance, a bale of the same material or any other suitable stop. (Not herein shown.) As such compressed material reaches the concave parts 8, a slight amount of expansion is permitted thereto, as this is about the limit of the forward stroke of the piston. As the piston or plunger head retreats, the detents lO-spring back into their normal position and prevent this compressed charge from flying backward. Upon the next forward movement of the piston or baling head with a fresh charge the charge which has just been left and held by the detents 10 is pushed out through the contracted ends 9 into the deliv- COIIlplGSSlOll-OllitlllbGl, and these ends, from their contraction, operate to fold down and smooth the sides of the bale, rendering it uniform and compact. As a further result of the contraction of ends 9, each charge of ma terial thrust.therethrough by the plunger is prevented from springing back to any extent into the compression-chamber, since as soon delivery-chamber its natural expansion is sufficient'to accomplish this result. Furthermore, the peculiar shape of the compressionchamber at 8 8 and the smallness of its discharge-extremity 9 9, as compared with the cry-chamber A. Ends 9 mark the exit of the as it leaves ends 9 and passes into the larger size of the delivery-chamber, are considered very important features, by reason of the fact that the strain on the machine is thereby principally confined to the compression-chamber, the other parts of the mechanism being correspondingly relieved.

\Vith some substances-such as hay, straw, &c.,there is always some of the material projecting outwardly from the mass above the baling-head, and to fold down and render the bales smooth what may be termed a folder is used. The folding device proper is shown at 14. This is composed of two faces or sides 15 16, the former, preferably, being the longer and merging into the latter at an angle. At the free end of side 15 the folder is pivoted upon a bolt 17, extending transversely across the forward end of the balin g-cha-mber. Upon the inner side of this folder, and at or near the angle thereof, lugs or cars are formed, in which is pivoted a bolt 18, which passes up wardly and is seated in the projecting end of the Ieafsprings 19, secured to one of the timbers, such bolt being secured to the leafspring by means of two jam-nuts 19 on the threaded portion of the boltone on either side of the spring-such jam-nuts and threaded portion permitting a vertical adjustment of the apex of thefolder relatively to the baling-chamber. This folder, it should be noticed, extends entirely acrbss the top of the forward end of the chamber.

In operation the folder is so adjusted that the surface 15 lies in the path of the upper part of the bale. As each successive charge is pushed against such surface by the balinghead it lifts the folder against the stress of the spring 19, the apex being in turn forced down when the plunger retreats and folding over any of the loose or projecting material.

By this construction and arrangement of devices an exceedingly smooth and compact bale is formed, especially where it is used, as I have largely used it, in the baling of hay and straw.

Having thus described my invention, what I claim is- 1. A baling-press having a compressionchamber 2 and a delivery ehamber A, the compression-chamber being somewhat e011- eave near its discharge extremity and at about the limit of the forward stroke of the plunger, as at 8 8,to permit expansion, thence decreasing in size to its discharge extremity S) 9, the delivery-chamber being contiguous and somewhat wider than the com n'essionchamber at its outlet, substantially as described.

2. In a baling-press, a compression-chamber2 and a delivery-chamberA, the two chambers being contiguous and their line of separation being distinctly marked by the contraction of the compression-chamber at its outlet 9 9, the compression-chamber having a curved enlargement near its outlet to permit expansion, substantially as described.

In a baling-press, a compression-ehamher 2, having a curved enlargement 8 8 near its discharge extremity and at about the limit of the forward stroke of the plunger, thence decreasing in size to its discharge extremity 9 f), in combination with the delivery-chamher A, somewhat larger than the discharge extremity of the compressioirchan'iber, substantially as described.

4. In abaling-press, a compression-chamber 2, having a curved enlargement 8 8 near its discharge extremity and at about the limit of the forward stroke of the plunger, the chamber thence decreasing in size to its dis charge extremityf) 9, and adelivory-chamber A, somewhat larger than the discharge extremity of the compression-chamber, in combination with the spring-actuated retainers 10, suitably located in the sides of the chamber, substantially as described.

5. In a baling-press, a compression chamber 2 and a delivery-chamber A, the compression-chamber being somewhat eonca-vcd near its discharge extremity'and at aboutthe limit of the forward stroke of the piston, as at 8 S, to permit expansion, thence decreasing in size to its discharge extremity 9 9, the delivery-chamber being somewhat larger than the discharge extremity of the eompressionchamber, in combination with a folding device arranged transversely across the top of the compressioil-chamber and consisting of a casting let, having two faces 15 and 16, and lugs on its inner side opposite their faces, a bolt hinged or pivoted to the lugs and extending upward therefrom, a leaf-spring 19, to which the upper extremity of bolt 18 is adjustably secured, and a pivot 17, upon which the forward extremity of the casting 14 is pivoted, substantially as described.

In testimony whereof I affix mysignature in presence of two witnesses.

MANETHO C. JACKSON.
