PETER K. DEDERICK, OF LOUDONVILLE, NEV YORK.

BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 334,004, dated January 12, 1886.

Application filed Oxtoher 20, 1885.

To all whom t 11i/Ly concern:

Beit known that I, PETER K. DEDERICK, of Londonville, in the county of Albany and State of New York, have invented certain new and useful Improvements in Baling- Presses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to'the accompanying drawings, forming a part of this specification, and to the figures and lett-ers of reference marked thereon.

This invention relates to improvements in powers for baling-presses, and has particular reference to that class of baling-presses known as perpetual or continuous presses, in lwhich the bales are formed or built up in sections by the operation of a reciprocating traverser or plunger within a press-case, acting upon successive charges of material fed to the press, and in which the power of the horses is applied through a reversible sweep or horselever.

In the most approved form of reversible presses, so called, as heretofore constructed, but one reciprocation of the traverser is effected by the movement of the sweep or horselever in one direction, the result being that only a single charge of material is pressed during the travel of the horse from one extreme of his movement to the other.

The object of my present invention is to increase the capacity of such a press by multiplying the number of reciprocations of the traverser produced during or by a complete movement of the horse-lever or sweep in either direction.v This multiplication of strokes I accomplish by combining with the pitman connected to the traverser and with a vibrating horse-lever or sweep suitable connections between the said sweep and pitman for causing the latter to approach and recede from a central line twice or oftener at each movement of the horse-lever in either direction, thereby effecting the desired result.

For the purpose of giving a clearer idea of the nature and scope of my invention, I have shown herein several of the many forms in which it may be embodied, not intending, of course, to limit myself to any particular embodiment, special features of construction being reserved for other applications.

Serial No. 180,448. (No model.)

Referring to the drawings, Figure 1 is a view in perspective of a press to which my invention is applied in one of its forms. Fig. 2 is a side elevation, and Fig. 3 a plan view, of the form of power shown in Fig. 1. Figs. 4 and 5 represent modifications of the embodiment of the invention as shown in Figs. 1 and 2. Fig. 6 represents another form of the invention, and Fig. 7 a modication of the same. Figs. 8, 9, and 1() are views of another form of the invention with the parts' in different positions. Figs. 11 and 12 represent a modification of the embodiment shown in the last three figures. Fig. 13 illustrates another form, and Fig. 14 a slight modification thereof. Figs. l5 and 16 represent another form of the invention. Fig. 17 represents another form. Figs. 18 to 22 represent still another form; Fig. 23, a modification of the last-mentioned form. Fig-24c illustrates a form of the invention in which the movement of the pitman is controlled without the, aid of a crank or crankarms, and Fig. 25 is a view of one form of antomatic reversible pawl such as may be employed.

. Similar letters of reference in the several figures indicate the same parts.

I have shown in Fig. 1 the application of my invention to a continuous or perpetual press. rlhe construction of presses of this type is so well known that herein I will only refer by letter to some of its principal parts.

A is the condensing-chamber, in which the material to be baled is fed and preliminarily condensed.

A is an automatic feeder for carrying the condensed charges down into the press-box A2, from whence they are forced by the traverscr A3 into the bale-chamber A4, where they are built up into bales, the latter being tied off and ejected through the open end of the bale-chamber as the operation proceeds.

No part of the press-frame nor the particular construction of the condensing mechanism nor the automatic feeder is herein claimed, since they form the subjects of prior patents or pending applications.

B represents the pitman, jointed at its inner end to the traverser, so that its outer end may be vibrated back and forth across a central line, being controlled in its movements by .zoo v suitable guides-such, for example, as swing ing crank-arms C, as shown in Fig. l, or fixed guides L, as shown in Fig. 24.

D is the horsellever or sweep. In all the 5 forms of theinvention herein shownthishorselevel' is arranged to vibrate across a central line and through connections, which constitute the gist of my invention, to operate upon the pitman in a manner to cause it to approach and recede from the central line, and thus produce reciprocations of the traverser.

In the form of the invention shown in Figs. 1, 2, and 3 the pitman is connected to and guided by the swinging crank-arms C, pivoted [5 at c, and the horse-lever is pivoted at a point,

d, in' front of the Divot of the crank-arms.

Upon the head of the horse-lever are arranged two bearings, D DS-one on each side,as shown in Fig. 3-while at an intermediate point is arranged a third bearing, D2.

In the dotted lines, Fig. 3, the parts are shown in the position they occupy when the traverser is withdrawn and the horses have reached one extreme of their movement and are about to reverse. It will be observed that at this time the intermediate bearing, D2, rests against one side of the crank-anus C. As the horses now move toward the opposite side, in the direction indicated by the arrow, the pressure of the bearing D2 upon the crank-arms causes the latter and the pitman to be brought up toward the central line. By reason of the ,crank-arms and the horse-lever being pivoted on different centers, the intermediate bearing jon the horse-lever is caused to travel toward t" the outer end of the crank-arms as the operai tion proceeds, and when the crank-arms and 1,pitman are nearly but not quite in line the isaid intermediate bearing passes beyond the arci end of the crank-arms, thus releasing thelatiter, whereupon the expansionof'the pressed materiah acting through the traverser and pitman, throws the crank-arms back to first position and in front of one of the bearings D or D3, and the latter, under the continued movement of the horse-lever, in like manner carries the crank-arms up to and this time past the central line, so that the expansion of the pressed material will throw the crank-arms back upon the opposite side and in position to be acted upon by the intermediate bearing, D2, when the horse lever is reversed. It will be seen that with this contrivance two reciprocations of the traverser are effected at each movement of the horselever in either direction.

The intermediate bearing, D?, instead of being fixed to the head of the horse-lever, may be arranged to have an independent movenient. To this end it may be constructed in the form of a swinging bearing, D4, limited by stops d', as shown in Fig. Ll, or in the form of a sliding bearing, D5, working within a slot, d2, Fig. 5. The effect of thus making the intermediate bearing movable is to allow .the swinging crank-arms to be thrown back farther when forced past the central line.

In form of the invention shown in Fig. 6 the pitman is extended past the point of connection with the crank-arms. and with it cooperate three bearings, F F2 F3, corresponding to the three bearings D D2 D3. These three bearings are formed upon the sliding bar F, which is reciprocated back and forth by the operation of the vibrating horselever through the medium of a drum, F, and chains F5.

Instead ofthe projections being formed upon abar, as shown in Fig. 6, stops ff2 f3 may be-secured directly to a chain, as shown in Fig. 7. rl`he number of intermediate bearings may be increased` so as to multiply the strokes of the pitman at each movement ofthe horse-lever, as will be readily understood.

Figs. 8, 9, and 10 illustrate in different positions another type of the invention. The pitman, horse-lever, and crank-arms are let tered B, D, and C, respectively, as before. The crank-arms in this example swing upon the pivot d of the horse lever. In Fig. 8 the parts are shown in the position which they occupy when the horse-lever commences to move from one side to the other. As the horse-lever advancesits point of cont-act with the pitman moves along the extension of the latter, and when the pitman and crank-arms are 'brought nearly in line the end of the horse-lever, by reason of the length of the crankvarms, is carried beyond and out of contact with the end of the pitman, as shown in Fig. 9, and the pitman, being thus released, is thrown back by the expansion ofthe pressed material into the position shown by the dotted lines in Fig. 9, and takes another bearing on the horse-lever. Then, as the horse-lever continues to move in the saine direction, it carries the pitman up to and over the center line, as shown in Fig. l0, the back expansion then throwing it to the opposite side, as shown by dotted lines in Fig. 10, in position to be operated upon in a similar manner when the horselever is reversed. In this embodiment it will also be observed that two reciprocations of the traverser are effected at each movement ofthe horse-lever.

In the modification shown in Figs. 11 and 12 the extended end g of the pitman is grooved on `opposite faces, as shown, for the passage of the bearings or shoulders g on the bifurcatedor slotted end g2 of the horselever. In starting, these bearings or shoulders g rest against the extended end of the pitman, and as the horselever moves from one side toward the other they are carried around said eXteudedv end, forcing the traverser forward until the crank-arms are brought near the center line, when the said bearings enter the grooves in the pitman and permit the latter to be thrown back to the starting-point, during which operation the extended end of the pitman passes between the arms of the horse-lever. The movement of the horse-lever being continued,

IIO

the pitman is carried up to and across the center-line, as before described.

Fig. 18 shows a construction in which the crank-arms and horse-lever are mounted upon independent pivots, and a bearing, H, on the horse-lever is adapted to engage with an extension, H', of the crank-arm, for the.purpose of bringing the pitman and crank-arms nearly to the center line, and then releasing them to make the first stroke during the movement of the horse-lever, lthe latteritself or a projection upon it being relied upon to carrythe pitman and crank-arms up to and past the central line for the second stroke during the continued movement of the horse-lever.

In Fig. 14 the same result is accomplishedI as in Fig. 13 by ,mounting` the horse-lever upon an axis, h, eccentric to the axis h', upon which the crank-arms are mounted.

- As shown in Figs. 15 and 16, the same effects may be obtained by employing a pivoted head, I, having bearings t' for engaging the pitman on opposite sides of the center. Said pivoted head is det-reliably connected to the horselever by means of a latch or bolt, I', which engages with one or the other of two notches, t" i2, in the said pivoted head.

Fig. 15 shows the position of the parts at the commencement of the movement of the horse-lever, the latch or bolt I being in engagement with the notch t2. As the horse-lever proceeds, the bearing i, which may be a roller, exerts pressure against the extended end of the pitman, and causes the latter and crank-arms to be brought nearly to the central line, at which point a cam, I2, or other suitable device or mechanism,operates to with-- draw or disengage the bolt i, whereupon the back expansion of the pressed material carries the pitman, crank-arms, and pivoted head back toward the position from whence they started, the latch or bolt I engaging automatically with the notch i on the opposite si de of the head, and thereby causing the horselever, in the continuation of its movement, to force the pitman and crank-arms up to and this time over the central line, and to a position on the other side corresponding to the tirst position.

.In the modification illustrated in Fig. 17 the p1tman,insteadofbeingattachedtoloosecrankarms, is connected directly toa pivotally-supported head, J, (preferably composed of two plates or disks mounted upon separate studs or axles j', and with the pitman located between them,) and said head is provided with notchesj'ljxjo receive a sliding bolt or catch, J on the horse-lever. The full linesindicate the position ofthe part-s when the movement of the horse-lever commences, the sliding bolt being in engagement with the intermediate notch, j. By the time the pitman has been brought nearly up to the central line the sliding boltJ" will be thrown out by atrip-such, for instance, as shown at ll3-thus permitting` the head to rotate backward, under the influence of the back expansion ot the pressed material, until its notchjlin turn becomes engaged with the sliding bolt, and the horse-lever, concauses the head to be again rotated until the pitman is carried up to and beyond t-he central line, whereupon the bolt JAZ is again disengaged from the head by the action of another trip, J". time the back expansion throws the pitman out at the opposite side of the press and brings the intermediate notch, ja, again into position tinning to advanceinthe same direction, then d As the head is released, this to be caught by the bolt or latch preparatory to -the reversal ofA the horse-lever. Two strokes of the pitman are eiiected by this construction at each throw of the horse-lever, as before.

In all the embodiments of the invention hereinbefore described in the stroke of the traverser first occurring during a single movement of the horse-lever in one direction, the pitman is caused to approach the central line and is then released and forced back toward the point from whence it started, while in they second stroke ofthe traverser,`ocurring during the same movement of the horse-lever, the

pitman is carried up to and past the central line and into position on the other side to operate in like manner upon the reversal of horse-lever. In other words, the pitman,during each movement ofthe horse-lever from one extreme to the other, first moves up to the central line and back again, and is then projected over the central line to a position on the opposite side corresponding to the position rst occupied. In Figs. 18 to 22, inclusive, however, is shown a construct-ion in which, during the continued movement of the horselever in either direction, the pitman is caused 1 to pass the central line at both strokes of the traverser occurring during said movement of the horselever,instead of at the second stroke only, as in the other forms ofthe invention.

Referring to said last-mentioned figures, it will be observed that there is connected to the swinging crank-arm or its shaft adisk or head, K, having oppositely-arranged projections k' k2, while upon the horse-lever there is mounted a double pawl or dog, K.

In Fig. 1S the parts are shown in position with the horse-lever at one extreme of its movement. Starting in the direction indicated by the arrows, with the pawl behind the projection 7c', the horse-lever operates to bring the pitman to the central line, as shown in Fig. 19, then carry it over the center when the expansion of the pressed material throws it and its connected parts around into the position shown in Fig. 20, thereby completing the first stroke and bringing the other projection, k2, in front of the pawl, so that by the continued movement of the horse-lever the pitman will be again carried up to the central line, as shown in Fig. 21, and over the same far enough to enable the traverser to be reversed by the expansion of the pressed material. As the pitmanA is thus forced past the central line the second time, the pawl is automatically tripped or reversed to bring its 0ppositeend in position for engagement with the IIO ISO

projection k, as shown in Fig. 22. Any wellknown form of automatic reversible pawl may be employed-for example, such as shown in Fig. 25, in which the pawl is provided with an angular projection or shoulder, k, against which the angular point of a spring-bolt, k6, works. The pawl is also provided with an arm or arms, k7, which, at the termination of the movement of the horse-lever in either direction, make contactwith aprojection on the frame, whereby the pawl is reversed.

This last-described form of the invention is also susceptible of being operated so as to cause the pitman to move up to the central line and back again, and then past the central line at the second stroke, as heretofore described, by tripping` the pawl just before the pitman reaches the central line the rst time in each movement of the horse-lever.

If deemed desirable, the disk or head K may be provided with a series of projections or teeth, as shown in Fig. 23, instead of with two only, as shown in the other figures.

In all the previously-described forms of the invention the outerend of the pitman is guided and controlled in its movements by means of swinging crank-arms; but any other contrivance which will serve to guide the said end of the pitman and maintain its operative relation to the other parts may be substituted. For instance, the pitman may be provided with projections adapted to work in a guideway arg ranged in or attached to theframe of the press. Fig. 24 shows a construction in which such a guideway is employed. Said guidewayis represented by the letter L, and the projections on the pitman by the letter L. The horse-lever or sweep is pivoted at Lg, and is provided with two bearingsJP-oneon each side-and an intermediate bearing, Z2, which bearings are in succession adapted to act upon the end of the pitman to carry it first up near the center, then release it and allow it to spring back, and then carry it over the center and allow it to spring back on the opposite side.

The full lines represent the position at the start, andthe dotted lines the position of the parts as the intermediate projection is passing out of contact with the pitman and just before the completion of the rst stroke.

The special devices herein shown in illustration of the generic invention, forming the subjectmatter of this application are not herein claimed, as they are embodied in separate applications, Serial Nos. 135,028, 137,578, 180,080, and 183, 735.
