ARTHUR H. BOE'ITCI-IER,V AND JOI-IN A. DIENNER, OF THE CO'PARTNERSHIP 0F BROWN, BOETTCHER AND DIENNER, OF CHICAGO, ILLINOIS Y BALIN G PRESS Application filed January 23, 1926.

My invention relates to baling presses and its objects are the provision of a generally improved and simplified construction that may be economically produced of standard or stock parts, one which will be durable and sturdy in service and into which the material may be conveniently introduced and the bales conveniently wired or tied and readily removed and in which the plunger or platen may be moved slowly and with great force or at a greater speed with less force, selectively as desired.

To acquaint those skilled in the art with the manner of constructing and carrying out .the invention, I shall now describe a particular embodiment of the same in connection with the accompanying drawings, in which:

Figure 1 is a. side elevational view of a device embodying the invention;

Fig. 2 is a front elevational view of the same with the removable front wall partially broken away to show the plunger;

Fig. 3 is a vertical section on line 3-3 of Fig. 2;

Fig. 4 is a top plan view;

Fig. 5 is a horizontal section on lme 5-5 of Fig. 3;

Fig. 6 is a detail perspective view of the ratchet wheel and co-operating pawl;

Fig. 7 is a perspective view of the member for moving the plunger relatively slowly and with a relatively great leverage.

Fig. Sis a cross sectional view of a modified form of pinion; and

Fig. 9 is a cross sectional view of a modified form of ratchet.

The device shown comprises a casing 5 of generally restangular cross section and .a plunger or platen movable vertically within the press chamber defined by the casing 5.

The bottom of the casing 5 is closed by a base 7, preferably of sheet metal. Mounted on the bottom or base 7 are a plurality of bottom or base members 8, conveniently of wood. These base members 8 are spaced or separated in the direction of the width of the device to provide spaces 9 (Fig. 2) for receiving the Wires or other bale tying means and said base` members are preferably of a thickness which will provide adequate space between the base Serial No. 83,181.

member 7 and the bottom of the bale for the convenient insertion of the wires or other tying means through the spaces 9 and beneath the bale. The bottom 7 and members 8 are secured along the front and rear of the machine as by bolts 10 to the inturned horizontal flanges of angle bars 12 which underlie the base 7 and extend in the direction of the width of the machine along the front and rear margins thereof.

The vertical flanges of angle bars 12 are secured as by rivets 13 to the upright vertical flanges of angle bars 14, the opposite ends of which angle bars 14 project beyond the opposite sides of the base of the machine. EX- tending across the projecting ends of angle bars 14 at opposite sides of the base of the machine with their horizontal base flanges secured as by bolts 15 to the projecting horizontal base flanges of angle bars 14, are a pair of angle side bars 16; The bolts may secure a pair of wooden supporting or base strips beneath the base of the machine, and these strips 18 may be of a length to provide proper support or bearing for the machine. The strips 18 may, of course, be otherwise secured in place or they may be omitted and the machine secured directly to the supporting surface or mounted otherwise, as desired.

rllhe casing 5 itself comprises opposite side walls 20, preferably of sheet metal, and conveniently of plate steel. The lower marginal edges of these side walls 20 exten/l down between the vertical flanges of angle bars 16 and the adjacent side edges of bottom 7 and members 8 and are secured as by rivets 22 to the upright flanges of angle irons 16. The rear portions of the upper edges of side walls 2O are cut off or finished obliquely at 23 so as not to interfere with the swinging movement of the press or platen 6 and associated swingably mounted operating parts.

The front edges of side walls 2O terminate in the pla-nes of said side walls at the upright flange of the front angle bar 14 and the open front of the casing is closed by a removable closure member orA front wall 25. This removable front wall or closure is like the other parts, preferably of sheet metal, conveniently plate steel, and a bar 26 secured to the upright flange of the front angle bar 14 and projecting thereabove, provides a space for receiving the lower edge of the closure and a retention for holding said lower edge in place (Fig. 3). The vertical margins of the closure plate 25 are turned baci; at substantially right angles at 28 to snugly embrace theside walls 20. A strengthening or bracing member', in the form of an angle bar 29, is secured horizontal-ly across the outer surface of closure 25 near its lower edge and a similar angle bar 30 is secured across the upper edge of the closure plate 25. A cross bar 32, conveniently an angle bar with the opposite ends of its horizontal 'flange removed and with the opposite freed ends of its vertical flange turned back at substantially right angles along the opposite side walls 2O and secured thereto as by rivets 33, is provided across the front edges of the side walls 2G above the front or closure 25. The inner ends of the rivets 33 are preferably counter sunk to avoid interference with the latch means for the swingably mounted platen or press parts of the machine.

For the purpose of locking the front closure 25 in closed position over1 the front of the machine, a latch bar 35 is provided. This latch bar 35 is pivot-ed at 3G to the median portion of the depending vertical flange of the cross bar 30 and its upper locking end is adapted to be swung through slots err- openings 37 and 38 rin the horizontal flanges of the bars 30 and 32, respectively, to lock the removable 'front closed. The slots or openings 37 and v38 are elongated in the direction of the width of the machine so that the upper end of the bar 35 maybe swung clear of the horizontal flange of bar 32 to permit ope-ning and removal of the front, which is done by swing ing it forwardly clear of the horizontal flange bar 32 and then lifting it up from between the bars 26 and 12 (Fig. 3). 1When the cover is in place the loweredges `of its back turned margins 28 may rest upon the upper edges of the vertical flanges of the side angle bars 16, and there is preferably suflicient clearance between the bar 26 at the lower edge of he front 25 and the bar l2 and adjacent edges of bottom 7 and members 8 to permit a limited swinging of the front 25 about its lower edge to clear the horizontal flange of bar 32. The lower end of the latch bar 35 may be offset outwardly to provide a suitable handle portion. l

' The rear marginal edges of side walls 2O are turned in at substantially right angles at 40 and these turned in edges 40 terminate lshort of the upper ends of the side walls at 42 so as to not interfere with the swinging movement of the platen and associated parts. The rear wall of the casing 5 is made up of a plurality of 45, preferably of sheet metal and conveniently, as before, of plate steel. The outer marvertical sections 43, 44 and Y.

ginal edges of sections 43 and 45 parallel the marginal flanges 40 internally and are attached thereto as by rivets 46. The inner marginal edges of sections 43 and 45 and the opposite vertical margins of intermediate section 44 are turned at substantially right angies at n48 and define vertical spaces for receiving the wires or other bale tying means, permitting said means to be projected therethrough and tied about the bale with the same in place in the casing 5, the vertical spaces 49 being in thel vertical plane of the base spaces 9. The upper edges of sections 43, 44 and 45 preferably terminate at the upper ends of marginal flanges 40 to avoid interference with the swinging movement of the platen and associated parts. Adjacent the upper edges of sections 43, 44 and 45, the margins 48 are turned back at 50, parallel to the rear wall sections and into the plane i of margins 40. An angle bar 52 extends across the upper turned baci; margins 50 and across the turned in margins 40 and is attached to the sides 2O and front sections through the margins 40 and 50 as by rivets The cross piece 52 braces and stiffens the rear of the casing and the inturned margins 50 reinforce the points of attachment. Adjacent the lower edges of sections r43, 44 and 45, the margins 48 are similarly turned `back at 54 into the plane `of margins 40 and t-he lower edges of sections 43, 44 and 45 are attached through said back-turned margins 54 to the upstanding flange `of the adjacent angle bar 14. j

The platen or press 6 comprises 1a metal plate 58 having secured to its under surface a plurality of boards or other members 60 spaced at 62 in the vertical planes lof the spaces 9 and 49, to receive the tying means about the top of the ba-le. Secured 'across the top of the plate 58 in the direction of the width of the machine, are a pair of .spaced angle bars 64, and extendingv from front to back between the vertical flanges of the bars 64 are a pair of relatively short angle bars 65, secured at their opposite ends upon the base flanges of the bars 64. The angle bars 65 are spaced to receive the lower end of a rack 68 `which is rigidly secured between said bars 65 at the median part of the platen 4or press.

In addition to the feature of making up the device of standard or stock, structural or wrought metal parts and the simplicity and economy in manufacture provided `thereby, the rack 68 and manner of making ilt up, is also an important feature of `my invention. I make'this rack from a :piece of channel iron of proper length. The base'69 of the channel 68 is provided with a series of slots 70 spaced uniformly to provide uni'- form connecting bars 7 2 which form 4the rack teeth and co-operate with the driving pinion. The slotting of the base y69 of the `channelbar is a simple matter and the side flanges 73 of said channel make the rack formed exceedingly strong in spite of the slotting of the base 69. In addition, they provide admirable mounting surfaces for the lower ends of the rack for mounting the rack between angle bars 65, as by means of an extension bolt, extending through both the flanges of the rack andV through both angle bars, or by means of 'separate bolts or a combination of the two, or otherwise.

A carriage, designated generally at 75, is swingably mounted over the open top of the casing 5. This carriage has means for guiding the rack and carries the operating or driving mechanism Vfor said rack. It comprises a pair of side plates 76 which lie against the outer sides of walls 20 and are pivoted at their lower ends at 77 between said walls and the vertical flanges of angle bars 78, said bars 78 being secured to the walls 20 with spacers 79 between them and said walls.

Secured to the upper endsof the side plates 76 with their longer legs depending vertically, are a pair of angle bars 80. These angle bars 80 carry the cross guides and operating mechanism for the rack. Mounted across the horizontal flanges of angle bars 80 with one above the other and the vertical flanges of both lying in substantially the same plane and presented, to the front edges of flanges 73 of rack 68, are a pair of angle bars 82 and 83. Mounted rearwardly of the bar 82 across the bars 80 with its vertical flange presented to the base of the rack 68, is an angle bar 84. The bars 82 and 84 are spaced sufficiently to just receive the rack 68 between them and thereby constitute a guide for guiding the rack. The bar 84 may he smaller than the bar 82 and spacers 85 may be. provided between the bars 80 and 84 to raise the bar 84 sufficiently for the accommodation of the pinion 86 beneath it, as shown in Fig. 3. Secured to the vertical flanges of the angle bars 82 and 83 with their free flanges presented to the sides of the rack 68, and guiding the rack in the direction of the width of the machine, are a pair of relatively short vertical angle bars 88.

The pinion 86 is keyed at 90 upon the shaft 92 which is preferably relatively heavy and of wrought metal. The shaft 92 passes through the depending vertical flanges of angle bars 80 and is journalled thereby at its opposite ends in said bars 80 and may be suitably held against axial or longitudinal displacement. Y

l F or proper co-operation with the teeth v7 2 forme-d b v punching slots 7 0 in the base of channel 68, I prefer Vto make the pinion 8G of mild steel cut from a round bar. In practice, I hob the teeth of the pinion 86 with a special cutter which forms the base 95 of each`.tooth substantially flat and the dedendums of said teeth substantially straight to the bases 95 without the gradual decrease in the spaces between the dedendumsand without appreciable rounding of the dedendums into the bases 95. This permits proper driving engagement of the teeth of the pinion with the teeth 72 of the rack, notwithstanding the generally rectangular Vcross section of teeth 72 and the flat outer surfaces of said teeth72 and this manner of producing the pinion is simple and inexpensive. The pitch circle of the teeth of pinion 86 may be positioned slightly nearer the bases 95 than is the usual practice.

F or V'positively holding the platen, press or plunger 6 at any position within its stroke, Iprovide a ratchet 96 and co-operating pawl 98. In practice, the ratchet wheel 96 is constructed from a disc of tank plate. The disc is placed in a proper fixture which is mounted in a multiple drill press, and all of the peripheral ratchet notches 100 and the center opening for receiving the shaft 92 may be drilled in one operation. This, and the construction of the pawl, to be described, together with the construction of the rack and co-operating pinion, and the general construction of the entire device, lends itself to economy and simplicity in manufacture. To provide the desired depth the notches 100 are, in practice, drilled inwardly of the periphery of disc such a distance that the peripheral opening is insufficient for t-he proper reception of the pawl 98. The peripheral opening may be increased by removing one corner only of each notch, as shown, which minimizes the operations and is consistant with low cost. The ratchet wheel 96 is keyed at 102 on the projecting end of the shaft 92, and its construction and the formation of the ratchet notches 100 provides great strength and positive holding engagement with the pawl 98.

A bar 108 swingably mounted upon the post 104 has a projecting pin 109 which, when the bar 108 is in the position shown in Fig. 1, lies adjacent the lower end of the pawl 98 in t-he path of swinging movement of said pawl in a clockwise direction and prevents swinging of the pawl without an accompanying swinging of the relatively heavy arm 108. The arm 108 is mounted near one end upon the post 104. the longer end 'providing an eccentrically disposed counter weight which holds the arm by gravity in this position. The weight of the arm 108 prevents accidental displacement of the pawl, but permits that swinging of the pawl which accompanies counter-clockwise rotation of shaft 92 and ratchet 96. W'ith the pawl 98 in this position, counter-clockwise rotation of shaft 92 is permitted for the purpose of moving the platen or plunger downwardly, the upper end of the pawl engaging successively in the notches 100 and holding or locking the plunger in any desired position, and the shaft 92 against accidental clockwise rotation. By swinging the ar1n108 in a clockwise direction about the post 104, the pin 109 engages the upper end of the pawl 98 and swings said pawl into the dotted line posi tion, shown in Figs. 1 and 6. lhen in this position, the lower end of the pawl 98, by its co-operation with the ratchet 96, prevents counter-clockwise turning of shaft 92, but permits clockwise rotation of said shaft for the purpose of raising the plunger or platen 6. The oil-center weight of the arm 108 holds said arm and the pawl 98, by gravity, in each of their two positions.

For the purpose of turning the shaft 92 relatively fast, as in raising the plunger or lowering it to the point where the pressure is placed upon the bale, the end of the shaft 92 has a longitudinal groove 110 for cooperation with a correspondingly keyed or feathered crank 112. yThe crank 112 is remove able from the shaft 92 and it provides for turning said shaft quickly, whenever relatively rapid movement of the plunger is desired and relatively great power is not required.

For the purpose of applying relatively great power, that is, for turning the shaft slower and with greater power for compressing the bale and placing the desired pressure thereon, a relatively long bar 115 is provided. The outer end of this bar may be linished to provide a suitable handle portion 116. A pair of steel or other relatively rigid plates 118 are attached, one to each of the opposite sides of the opposite end of the bar 115. The bar 115 spaces the plates 118 so that they may straddle the ratchet wheel 96, and the free ends of plates 118 are notched at 120 to fit over or straddle the shaft 92, as shown in Fig. 1. Extending between and suitably secured at its opposite ends in the projecting ends of plates 118, is apost 122, which, by straddling the plates 118 over the ratchet wheel 96 and the slots 120 over the shaft 92 on opposite sides of said ratchet wheel, may be engaged with either of theratchet notches 100 to effeet driving connection with the shaft 92 through the ratchet wheel 96. `The bar 115 is relatively long, as compared with the crank 112, and it is of relatively great strength so that a relatively great leverage may be had upon the shaft for compressing the balev and placing the desired pressure thereon.

' For the purpose of latching the swingably mounted cradle, in proper vertical position for the proper' operation of the plunger, a pair of latch bars 180 are provided, one pivoted at- 182 upon each of the angle bars 80 and provided at their free ends with notches 134i for engagement with the upper edge of the cross bar 82, as shown in Fig. 3.

In use, the latch bars 180 are released and the entirev carriage with the plunger, and plunger operating means carrie-d thereby, is swung into the position shown in dotted lines in 8, the plunger 6 being first preferably raised so' that it will clear the upper edges of therear wall sections of the casing, as shown, and so that when swung back into place it will overlie the material to be compressed and baled. This positioning of the plunger and plunger operating parts permits introducing the material to be baled into the top of the casing 5. When it is desired to compress and bale the material in the machine, the carriage 75 is swung back into its full line position (Fig. 3) and the latches 130 are engaged with the upper edge of the cross bar 32 to lock the carriage, plunger, and operating parts securely in this position.

If some downward movement of the plunger 6 is required before appreciable compression of the material takes place, this movement may be accomplished relatively quickly by mounting the crank 112 upon the shaft 92 and turning said shaft in a counter-clockwise direction, the pawl 98 having been' positioned as shown in full lines in Fig. 1, to permit this downward movement and to engage the ratchet 100 and hold the plunger and operating parts in any desired position. As soon as a greater effort is required to place the desired pressure on the baled material within the casing 5, the crank 11,2may be removed and the lever or handle bar 115 engaged with the ratchet 100, as already pointed out, and operated to continue the turning of shaft 92 in a countenclockwise direction with greater effort. y

`With the bale compressed and under pressure, the front cover 25 may be removed and the tying means threaded through the spaces 9, 49 and 62, and tied as desired at the front or back of the machine. lVhen the bale has been properly tied the pressure upon it may be released by raising the plunger 6, whereupon the bale may be conveniently removed from the open front of the casing 5, the cover or front closure 25 replaced, and the carriage 75 again swung to its dotted line position t0 permit the introduction of material for another bale.

In Fig. 8 I have illustrated a modilied form of pinion 86 consisting of a plurality of laminations 200 secured together in any suitable inanner, such as by rivets 199.

In Fig. 9 I have illustrated a modifiedv form of ratchet 96 comprising a plurality of laminations 201 secured together by rivets 202.

In practice I have found that ratchets and pinions of the above form are very durable and are strong enough to withstand the high pressures and forces to which they may be submitted in operation. Moreover, the laminations may be bla-nked of steel plate to the desired shape and contour of the finished gear or ratchet, by the ordinary punch press, and they may be of any thickness up to approximately ,g inch. Then too, this method of construction considerably reduces the cost of manufacture, and as previously mentioned,

iso

greatly increases the strength of both the ratchet and pinion.

I claim:

In a device of the class described, an enclosing casing, a removable closure therefor, a carriage swingably mounted on said casing, latch means' for the closure, latch means for the carriage, and a common cross member with which both said latch means (zo-operate to lock the closure closed, and the carriage in operative position.

In Witness whereof, I hereunto subscribe my name this 3rd day of November, 1924.

CHARLES A. BROWN.
