SPECIFICATION forming part'of Letters Patent No. 362,884, dated May 10, 1887.

Application filed January 3, 1887. Serial No. 223,224. (No model. lV

To @ZZ whom it may' concern: v

Be yit known that I, GEORGE ERTEL, of Quincy, in the county of Adams and State of illinois. have invented a new'and Improved Ealing-Press, of which the following is a full, clear, and exact description.

My invention relates to presses for baling hay, straw, cotton, or other material., and has for its object to provide a simple, effective, and durable press of this character, combin-v ing improvements allowing very 'easy operation of the plunger, and insuring a folding of the balable material at .the rear end of the baling-box feed-opening without catching the material, 'thus promoting efficiency of the plunger and insuring the easier feed of the press, and finally providing forautomatic adjustment of the press-case walls toaocommodate varying conditions of the material being baled and a variable feed of it to the press.

The invention consists in certain novel features of construction and combinations of parts of the press, all as hereinafter fully described and claimed.

'Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures. 1

Figure l is aver-tical longitudinal'sectional Fig. 2 is aplan view of thepress. Fig. 3 is van enlarged vertical longitudinal sectional elevation. of the central parts of the press. Fig. 4 is a sectional plan view thereof, with the feederplatform removed and its braces broken away.

Fig. is a rear end viewof the press-ease, thefeeder-platform and its braces being broken away. Fig. 6 is a transverse vertical section ofthe press-ease taken on the line w x, Fig. 3,

box, a, for the drawn-back plunger or follower, a baling-box, B, in rear ofthe plunger, and a bale-chamber, O, in rear ofthe baling-box, and from which the pressed and tied bales are discharged as they are continuously formed between grooved spacing-blocks used in a well bounds and is clamped automatically at the 'top and pressed to the floor of the case to pre` vent violent shocks to the case and the power mechanism by means of a brake-lever, E, which is hung tothe top of the press-ease on a springactuated fulcrum piu 'and block at e, and has a wedge-block, e', and a metal plate, e2, which act, respectively, on an inclined block, d', and plate d2 'on the top of the plunger. y

Averticallyadjustable fulerum and thrustpin', E', is fitted into a crosstimber of the presscase and may be set to regulate the pressure the brake'lever will exert on the reboundingplunger. Thisbrake-levermechanism is described in my. prior patent, No. 349,934, dated September 2S, 18.86, and therefore needs n o further detailed descriptiou,aud is' illustrated here as a preferred form of brake or clampacting on the backend ofthe plunger ward or outward stroke the plunger is clamped' to the tloor ofthe press-caseby the brakelever E,.and' until on the forward or acting stroke of the plunger it is forced to the floor of the press-case by an automatic folder, G, which op'eratesialso as a resistance-bar, as

presently described. It is obvious that a sin- `gle roller F may be placed. 'beneath the IOO Il?, which inclines or- 3o being fed to the press-box or forced along it 'is formed, preferably,

pl unger; but the two shown are preferred 5 and whether one or two or more rollers are used I will provide pinsfin the base ofthe plunger, which project into the lollergrooves behind the rollers toprcvent' their backward displacement; and I also make openings Fin the plunger-base, through which the rollers may be easily removed after the pins f are withdrawn. l

The folderG is a metal block or angular plate, which is pivoted on a heavy bolt, g, at the'upper wall of the press-case at the rear end of the feed-opening b of thepress, and so'that the angle formed by the meeting of its two parts or faces, g g2, normally projects within rthe balingbox B, as shown in Fig. 1 of the drawings, in which position the contact of a lip or lug, g, at the upper edge of its part y', with a projecting lip, ha, at the cor-A ner of an angularnietal plate, H, which is held to the press-case next the folder by bolts h, and of two parts or united vertically,and theother, slants downward at its under face from the lip or lug lr, toward the rear part of the baling box. A 'spring or springs, l, placed between the folder and the outer lining of the press-case, assure the normal pendent position of the folder,which thus ol'i'ers resistance to the hay or other substance plates,one,h, ranging by the plunger to fold the hay down into the baling-box in advance ofthe plunger. Alip, g, at the corner of the folder strikes the lip It3 ofthe plate H to limit. the upward swing of the folder as the plunger moves beneath it to the extreme of its forward stroke, and the outer'face of the part r/"of the folder is formed on an are described from the `folder-pivot as a center, and rconsequently `will always move closelyto the edge of the lip hi* of the plate H as the folder is swung upward by the plunger,

' box.

andwhereby the hay or other material beingbaled will be prevented from passing up behind the folderand ,catching between it and the press-case or the plate H fixed thereto to'impede the operation of the plunger. This folder G somewhat resembles theretainer T shown in my Patent N o. 349,934, dated Septomber 28, 1886; but the retainer T is liable to catch the material being baled between it,and the press-case, and I would remark that this is an instance where a difference in form eects vastly improved results in practical operation.

plate H extend for the full width of the press- II is not essential to the successful operation of the folder G, as the top cross-timber ofthe press-case next the folder may be provided with a lip the .substantial equivalent of .the

one 'h3 on the plate H, and against which the folder-lips g3 g" may stop, and next which the convexed face of the part gof the' folder may move; or the folder-li ps gig* may stop' against a corner of the press-ease timber, which may' itself act as does the lip if on the plate 1I.

the expanding hay' or other folder is heldby.

-ordiagonal slot, M, which Both the holder G andl Itwill vbe understood that the platel This part H, however, forms an effective wearplate'or guard to protect the timber of the press-case next the folder, and therefore its use is preferable.

Retainers J are pivoted on vertically-rang ing rds or shaftsj at each side of the presscase, and have lugs or hooks K, which project throughthe case into the baling-box, and so that the forward shoulders, 7c, of the hooks which receive the back thrust or pressure of pressed by the plunger stand about in line vertically with the folder G, which latter also assists or may assistl the retainers by its corner lip, g4, in preventing undue expansion of the pressed material as Vthe plunger moves backward prior to feeding the next charge of hay to the baling-box. 'Springs L, placed between' the backs of the retainers J, behind their hooks K, and entering fixed to the press-case, normally force the hooks into the baling-box, but allow them to be thrust back by pressure o'f the plunger until the charge of hay passes the hooks, which then spring in to retain the hay.

It will be noticed that the pivot-rods j of the hookfretainers J are placed at the forward ends of the retainers, or nearest the drawnbaek plunger, and that the hooks lhave lips or lugs k which press against the outer faces of the` side walls of the press-case with great force, as the hay in expanding presses against the hookshoulders la, and both the hooks K and the pressing inner faces planes nearer the eenterof thepress-case than the pivot-rods j of the retainers; hence the greater the pressure ofthe expanding hay against the hooks the greater will be the bracing effect of the hook-lugs 7c on the press-ease to prevent bursting .or overstraining of the case at the billing-box, and the' retainers are not liable to slip or lose hold of the pressed hay, as they are when their pivots are arranged at their ends farthest from the drawn-back plunger, as shown in prior patents granted to vThe floor of the balingbox B is provided with a dust-exit and bale-cleaning transverse is also particularly described and claimed in my aforesaid Patent N o. 349, 934.

The operation of the plunger with relation to the back clamp, the automatic folder, and

of their lugs 7c stand in A substance last suitable supports, Z,

IOO

the retainers is as follows: When the Dlunger' is fully back, as in Fig. l of the drawings, va charge or increment of hay or other material to be baled will be fed to the baling-box B, and asp-the plunger is forced forward-for its effective stroke by the power mechanismi the weight of the plungenwill be sustained on the rollers F, which thus hold the plunger clear of the door of the press-case, so that it moves to 'its work with very little friction. As the plunger-head approaches the folder G, and about when the freely-nioving rollers reach a posi-` tion indicated in dotted lines in Fig. 1 and in full lines in Fig. 3, the weight of the head or forward end of the plunger, together with the resistance offered by the folder G, will overbalance the plunger forward on the rollers, so that the forward end of the plunger is forced to the press case floor and the friction-rollers, are relieved of heavy pressure as the plunger is being forced forward under maximum power of the driving mechanism to the extreme limits of its forward stroke, or to the position shown in Fig. 3 of the drawings. As the head of the plunger forces the hay inward beneath the folder G, which has also been raised, as in Fig. 3, by the pressure, the hay above the lip g* of the folder is bent or folded over by said lip, and as the folder swings upward the closeness of its part g' yto the adjacent lip, h3, y, of the plate H prevents passage of the hay behind the folder. Consequently all the hay will freely pass rearward into the baling-box `beneath the folder and will not bind the plunger. Neither can the hay as itexpands when the plunger is thrown backward on its return stroke force its way behind the folder or bctween the folder and the plate H or the pressease; hence the succeeding charge of hay next pressed into the balingbox by the plunger will easily force the last-pressed charge rearward into the press-case on the next effective or l'orward stroke of the plunger. As the outer end of the plunger-pitman passes the center, or, in other words, when the end of the plungerpitman connected to the power mechanism is carried past the transverse center of the presscase, the plunger is forced backward toward its first position by the expansion of thepressed hay. lhe retainer-hooksK will catch the hay and limit its expansiomand the expanding hay also willvoperate to swing or turn t-he folderG downward to its first posit-ion ready for operaA tion on the next forward stroke of the pl'u nger, and the folder also will operate as a retainer to hold back the pressed material, although it is intended that this will be done chiefly by the retainers J K, torelieve the folder ot ex-- cessive strains. When the plunger on its backstroke escapes from beneath the folder G, the springs I will instantly swing the folder down on its pivot g to the position shown in Fig. 1 ofthe drawings, loosestraggling materia-l down into the balingbox'prior tothe pressing of the next batch of material by the plunger, the folder thus assuring smoothsided bales and permitting quick and effective working-of the press without requiring a door at the baling'- boX opening,

thereby saving time and labor in pressing the bales.

Immediately the plunger pitman passes the center and the expanding pressed material throws back the plunger D, the latter, after escaping from beneath the folder G, will again befree, and will bear onto the anti-friction rollers or carriers F, which will support. the pl'unger and assure its very easy and smooth travel, and with little t`rietion aud wear, untl` the rollers nearly reach` the position shown in full lines in Fig. l', and about as and the lip g* will fold the` overbalances backward on the rollersit'will be clamped atits back en (orother devices suitable for this purpose) to the door of the press-case, to prevent shocks to the power mechanism and other parts of the press, and the rollers F will be relieved of considcrable of the weight of the plunger and its pitman.

On the next forward stroke of the plunger, and immediately it is moved from beneath the brake-lever or clamping device, as E, the plunger will again be supported clear of the floor of vthe press-case on the anti-friction rollers F until it overbalances forward about as, or shortly before, it reaches the folder in pressing the last-fed charge of hay or otherbalable material, Should the rollers F cause too free or easy travel vof the plunger, as at times may occur in extremely dry weather and when baling very dry material, it is the work of a few minutes only to withdraw the pins f from the plunger, and remove the rollers from bei neath the plunger through the openings d3 therein, and the rollers may easily be replaced beneath the plunger when necessary.

` To promote convenience in feeding t-hepress,

l provide the platform N, which is held to the press-frame, with an opening, O, adjacent to the feed-opening b ofthe press case. This construction, instead of compelling the feeder to stand upon the platform to feed the hay to the press by forkin to stoop or erouch upon the platlornnwhen feeding the press directly by the hands, allows the feeder to stand upon a support placed below the platform-a few bales of hay, for instancc-and with his body-through the opening O of the platform, with his waist, thus allowing the feeder by an easy movement of his arms or hands to sweep the hay or other ,substance from the platform directly into the feed-opening of the balingbox,and which he may do for a longtime without'fatigue, thus effecting a considerable saving in labor over the other above-named methods of feeding the press. The opening O is preferably made round and near the inner edge of the platform; but it may be cut in from the edge, as indicated by the dotted lines o o in -Fig. 2 of the drawings.

The feeder-platform N may be held to the press-frane i-n any approved way, apreferred plan being by means of links n n, which conti mber of the frame of thepress-case, and l braces l?, which give support tothe outer edge or part of the platform from the lower corner timber of the case.

The two opposite side walls, R R, at the forward or power end of the press-case extend rearward from points i', next the plungerbrake device E, orits equivalent along the baling-box B, to points r', whence the sides of the press are open to its back end to allow ltying out the bales.

Hence the frction-snrfacesof the bale-chamber over which\ the bales are forced by the plunger never vary in area, however the top and bottom of the press are adjnsted or held by the spring or springs X, and there are no slots or open corner joints into which the pressed material would be forced to bind and clog the press, as when side walls are used with expansible top and bottom walls. Furthermore, the opposite somewhat-loose side timbers, 19, near the back end ofthe presscase, hold the top and bottom wallsin proper relative positions, while allowing free adjustment of the walls; and I find by practical tests that my construction of the bale-chamber without side walls, as'above described,allows the nuts w of the retaining-bolts W to be tight-y ened orloosened easily and quickly by atwclve inch wrench, even when the pressure of the plunger is from eight to ten tons; and, finally, the construction with corner timbers, A, walls 'U V, and thecross-barsand bolts and nuts W w is quite inexpensive and very substantial and durable.

Truss-rods Y, 'connected to the ends of the lower frame-timbers, A, one at each side, are strained over a cross-timber, 22, on theA frame below the baling-box B, to give rigidity to the entire structure.
