To aZZ whom it may concern.-

3e it known that we, WILLIAM GLADER, a resident of Chicago, in the county of Cook, and HENRY SCHMIDT, a resident of Elgin, in 5 the county ofKane, State oflllinois, citizens of the United States, have invented certain new and useful Improvements in 'lrussing-lliachines,of whichthefollowingis aspecitication. This invention relates to improvements in KO trussirig-machines in which the truss-hoops are rigidly held and the slaves forced through the truss-hoops in the final trussing operation preparatory to receiving the permanent hoops and otherwise finishing the article for the market, but more particularly relates to that class of trussing-machines especially adapted for trussing butter-tubs and other analogous articles, in which the staves are simultaneously driven through the trusshoops and evened by the single stroke of a plate, weight, or other driver operating with continuous pressure upon the ends of the staves and forein g them downwardly through the truss-hoops against a fixed bottom, limiting the downward movement of the staves. In the trussing-machines now commonly employed, and particularly for trussing butter-tubs, the set-up tub after being fired is placed in a pot or between standards having shoulders or notches immovably supporting the truss-hoops, and the tub is trussed by repeated blows on the ends of the staves from a falling weight suspended over the pot or standards, the blows of which weight drive the staves downwardly through and tighten them in the truss-hoops, a fixed bottom in the pot or standards limiting the downward thrust of the staves. In the most approved constructon of butter-tub trussingmachines now commonly used the truss-hoops are supported upon annular ledges or shoulders in a potimmovably arranged between vertical rods or standards, which serve as guides for the falling weight, said weight bcing lifted by means of a Windlass and maintained in an elevated position by a clutch device until the clutch is actuated to release the weight, which then falls onto the ends of the stares, operating to drive the staves through the truss-hoops. Butter-tub truss ing-machines of this general character-that is to say, in which the pot and standards are fixed and a falling weight is used, whether or not a clutch mechanism is used in connection with that weight-are found in actual use to be objectionable, first, because in putting in 5 and taking out the tub the operator must project his hands in the path of the falling weight, and the resultis that he is frequently injured by a premature release of the weight, as often occurs in rapid operation of the ma- 6c chine; second, because the concussion of the blows of a falling weight and their necessary frequency subject the entire machine to a a strain often resulting in breakage of its parts v and necessitating frequent repairs, thereby incurring objectionable expense and lossof ti me; third, the concussions of the falling weight are not only objectionable, because of the noise they produce, but because of jarring and sometimes injuring the floor upon which the machine rests; fourth, because the hammerlike force of the blows of the falling weight frequently result in splitting or otherwise injuring the staves to such an extent that the tub must be knocked down, reset up, and again fired, when sound stavcs are substituted for the bad ones; fifth, because with a falling weight such tubs cannot be uniformly trussed, for with a falling weight neither the force of its blows or the number of its blows necessary to truss a tub can be regulated or predetermined, and, finally, because the use of a falling weight, requiring, as it does, a series of blows to truss a single tub, involves an objectionable loss of time and resultant expense in the trussing of buttertubs. These are but few of the many objections to dropweight trussing-machines, all of which a prolonged practical use of our invention demonstates it to fully overcome and effectually provide against, as will now be more fully set forth.

Amongthe important objects of this invention is to automatically feed the article to be trussed into and discharge itfrom a trussingmachine, whereby the operation of the machine is quickencd and possibility of danger to the attendant is wholly avoided, and the tubs so centered under the stave-driver that the pressure thereof is uniformly distributed to each and evcrystave and alike to every tub. A further object is. to thus uniformly drive Lil and even the staves by a single stroke of the driver, and in such a manner that there is an entire absence of any objectionable jarring of any part of the machine and liability of the staves in any given number of tubs may 7 be uniformly trussed, and the strokes of the driver may be changed to conform to staves varying in lengththat is to say, to staves in tubs or other articles of differing heights.

Another object is to have a driver so constructed that all of the staves are uniformly gatheredthat is, moved inwardly to their final position in advance of their being driven home through the truss-hoopswhereby during the action of the drivers the staves have no lateral or frictional movement against the face of the driver, and are therefore subject to no strain tending to mar their edges or splinter them.

Another objectis to prevent any possibility of the staves adhering to the gatherer and thereby being lifted by the driver as the latter is moved away from the staves after trussing them, and to accomplish this end by simple and effective means not liable to get out of order.

One of the more important objects of this invention is a trussing-machine in which the article to be trussed is automatically fed to or moved under the driver for trussing and away from the driver after being trussed that is to say, a machine in which the pot, standards, or other device receiving the setup tub and supporting the truss-hoops is mechanically and automatically movable in and away from the path of travel of the driverwhereby the attendant of the machine is entirely removed from danger by the action of driver, the article to be trussed is with certainty centered under said driver, the placing of the article and its removal from the pot or standards are facilitated, and the operation of trussiug substantially and matcriallyquickened.

Another object is to have the pot or standard-supporting carriage transmitting the tub into and out of the machine of such a character that it is movable with the minimum amount of friction and yet capable of solidly sustainingthe'full impact'of the driver without injury to or undue pressure upon the antifriction devices constituting the support of the carriage during its back-and-forth travel.

A still further object is to have such a connection between the stave-driver and the supporting-carriage that the time of their movement will be such that the article to be trussed is with certainty centered under the driver before any of the staves are subject to its action and that no outward movement of the carriage shall take place until the driverhas receded from contact with them, and, finally, certain other objects to be attained, which are hereinafter described, claimed, and shown in the accompanying drawings, in which Figure 1 illustrates a side elevation ofa trussing-machine embodying our invention and showing the position of the several parts when the stave-driver is at the limit of its upward stroke and the automatic feed-carrier at the limit of its outer stroke with the pot, having therein a butter-tub in position to receive its final trussing; Fig. 2, avertical central longitudinal section of the same, with the le ver-and-link connection of the traveling carriage shown in elevation; Fig. 3, a detail sectional view of the stop device, limiting theinward movement of the feed-carrier; Fig. 4, an enlarged detail sectional View of the stavedriver, more particularly showing the form and arrangement of the gathering device secured thereto; Fig. 5, a detail longitudinal section of the feed-carrier and its bed-plate on the line 5 5 of Fig. 7; Fig. 6,avertical section through the pot on the line 6 6 of Fig. 7, more particularly showingthe latch devices, preventing the driver lifting the trussed article during the retreat of the driver therefrom; Fig. 7, a top plan view of our machine with the driver and all that portion of the machine above the pot removed; Fig. 8, a detail side elevation on the line 8 8 of Fig. 7, showing the latch connection between the throw-off lever and the crank-shaft connection with the movable carriage, whereby the carriage is automatically stopped at thelimit of its backward stroke, and Fig. 9, a detail elevation of the end of the rocking lever.

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

The frame of our machine consists of a base A, to each side of which are bolted or otherwise secured bifurcated standards B, the upper and stem ends of whichB are vertically slotted and connected by a cross-bar B cast or otherwise secured thereto. Along the rear side of this frame-work is a power-shaft C, journaled in brackets C, bolted or otherwise secured to the standards B, on one end of which shaft is a belt-wheel C made fixed or idle thereon by a clutch D, which may be of any ordinary construction, and therefore not shown in detail, the opposite end of said shaft having thereon a fixed pinion C meshing with a gear E on a shaft E extending en- "tirely across the mac'hine,'and having fixedv thereon next the gear E a pinion E in turn meshing with a gear F, fixed upon a shaft F, which, like shaft E, (see Fig. 1,) is journaled in the base A and, as indicated by dotted lines in Fig. 7, extends entirely across said bedplate and has upon its end a gear G, meshing with a pinion G on the shaft E, as indicated in Fig. 7, whereby the power of said shaft E is uniformly distributed as nearly as may be to both ends f, the shaft F, and the gears F and G thereon; but it would be no substantial departure from this invention to have the shaft E a short shaft, omitting the pinion G, and with it the wheel-like structure of the gear G, for, as will now be shown, said gear G is in operation simply a crankarm on the shaft F; or, in other words, gears and G are each provided with crank-pins F on which are pivoted crank-rods II II, respectively, preferably made in two parts, connected by turnbuckles I1 one of which only is shown in Fig. 1, provided for increasing and decreasing the length of these crank-rods for the purpose hereinafter described.

Crank-rods II II are respectively pivoted to boxes I, one of which is shown in Fig. 1, having a vertical sliding movement in the slotted upper frame-work B, which said sliding boxes are secured to a cross-head I, to which the driver J is attached, but may be secured to the driver, a rod I ,secured to this cross-head or to the driver, and bearing in,

' the cross-bar I5 serving as an additional guide to directthe driver; but the omission of the guide-rod 1 would not be a substantial departure from our invention. By this red connection of the driver with the crank-pin F of the gear I the driver is operated, and the range of its stroke maybe changed by adjust ing the turnbuckle H whereby the stroke of the driver may be varied for staves differing in lengththat is to say, while the stroke of the driver always remains the same, by lengthening or shortening the rod 11 the range of the action of the driver will be changed, and it will be brought nearer to or farther from the trussing-pot or bed of the machine at each stroke, according to the adjustmentand by this turnbuckle the stroke of the driver maybe so nicely adjusted that its downward stroke ceases as soon as the lower ends of the staves reach the bottom of the pot or bedplate thereof, which they are caused to do by a single stroke of the driver, and when so driven the final trussing of the tub is completed. In this connection it may be observed that if the upper ends of the staves are not all even during the descent of the driver thereon they will be with absolute certainty the moment the driver has completed its downward stroke.

The pot K except certain slots hereinafter referred to, is of the usual form-that is to say, is provided with shoulders I 2 3, in which the truss-hoops l, 2, and 3 of the butter-tub or other article to be trussed rest, and next its bottom with an annular flange at, constituting the bed or base plates thereof, upon which the ends of the staves rest when fully driven into the truss-hoops; but if preferred said base 4 maybe formed by a ring or plate set in the bottom or by a solid bottom in the pot. A butter-tub or other-article to be trussed is placed in this pot with the truss-hoops resting on the shoulders 1 2 3, in which position the lower ends of the staves or some of them are above the base {of the pot, which during the operation of trussing is centered under the driver. As the staves are driven downwardly through the truss-hoops, all of them necessarily bodily and laterally move inwardly toward the axis of the tub,and this is true whether said staves are driven by a falling weight, by a hammer of any kind, or by the continuous single stroke of a driver actuated by crank-arms, as herein shown, or by cams. The effort of this inward movement of the staves is made during the contact of the driver with the stave ends, the result being in practice that not only are the stave ends sprung, splintered, and otherwise disfigured and injured to an extent frequently requiring new staves to be substituted for the injured ones, which involves a resetting up of the tub, and if more than one stave is injured a retiring of the same, but a resistance to the action of the driver, only overcome by an increase in the force of its blow, promotin g the frictional resistance and the tendency of the staves to injury. By our invention, however, no such frictional resistance can occur, and the force of the driver is exerted throughout its stroke on a line directly through the staves from end to end, and the staves are perfectly trussed by a blow, the force of which is so reduced that it cannot possibly injure the staves in the least. To these ends we employ a device termed for convenience a gatherer, because it gathers the staves to the limit of theirinward movement before the driver can exert its full force to drive the staves downwardly through the truss-hoops. The gatherer consists of a ring J, bolted or otherwise secured to and projecting below the striking face of the driver, which, by the way, is preferably slightly concaved, so that its force is exerted on a line directly through the staves from end to end after they are gathered to the limit of their inward movement. Gatherer J has its inner face or edge J 2 flaring or bell-shaped from its upper or inner edge toward its lower or outer edge, as more clearly shown in Fig. t, the diameter of the lower edge or perimeter of said gatherer being as great or greater than that of the tub before it is trussed and its uppen edge diameter corresponding with the least outer diameter the staves can have when finally trussed, so that immediately said gatherer comes in contact with the staves it gradually forces the staves inwardly until they reach the limitof their-inward movement, until which time the face of the driver can have no contact with the staves. Now as the driver descends the staves are first moved by the gatherer to the limit of their inward movement and the driver continuing its descent drives the staves home through the trusshoops, and by these means not only is a lateral frictional movement of the staves against the face of the driver entirely absent, but the staves are broughtinto the best possible position for utilizing the force of the driver, the

IIO

result being that a much less force is required to drive the slaves home and theforcenecesency may be and is entirely prevented by the employment of very simple devices consisting of one, two, or more latches 5 5, (see Fig. 6,) pivoted at their lower ends toward or near the bottom of the pot and terminatin at their upper ends in hooks, which when the pot and tub are under the hammer project through slots 7 7 in the upper edge of the pot and lap or hool: over upon the upper truss-hoop, thereby holding the tub down in the pot as the driver ascends. These latches are actuated to make their inward movement by means of fixed spring-arms 8 8 as the carriage hereinafter described, moves to carry the pot and tub under the driver, but which are caused to recede from the truss-hoop and release it by means of springs 9 9, (see Fig. 6,) confined between the latches and the pot and in staples 1O 10, which serve to limit the outward movement of the latches, it being understood that when the tub is at the limit of its outward stroke the latches are disengaged from the spring-anus S 8, when they are-actuated by their springs 9 9 to release the truss-hoops. ()ur invention, however, is not limited to the special form or means of actuating such latches, but broadly includes any form of latch actuated by hand or automatically to hold the tub down in the pot as the driver ascends after completing its stroke, for, so far as we know, devices of any kind for this purpose are wholly new.

I As before stated, there is a serious objection to crossing-machines as now employed, because of the danger to the attendant in the putting into and taking the tubs from the machine, for that in the machines now commonly used the attendant both in putting the tubs into the machine and taking them out must put his hands into the pathway of the driver in taking hold of the upper edge of the tub to lift it out of the pot, the result being that not infrequently the driver will inju re the attendant either by an accidental fall or in the course of a rapid operation of the machine, and several instances of this character have resulted in crushing the hand and fingers of the attendant.

One of the mostimportant features of a trussing-machine embodying our invention is the entire absence of any possibility of injury to the attendant by the driver, and by reason of our invention automatically feeding the tub under the driver and entirely removing it from the path traveled by the driver immediately the tub is trussed ready for removal. To accomplish this novel and important result, the pot K is mounted upon and secured to a carriage L, which maybe supported upon the base A of the machine, but is preferably so supported upon a bed plate M. In order that this carriage may freely move upon the bed-plate, it is mounted upon anti-frietion rollers 11 11 (see Fig. 5) and in a peculiar and novel man ner, for, obviously, no rollers pivoted directly to the carriage could have their pivots withstand the force of the driver, and if they could the carriage would not be sufficiently solid for thoroughly practi cal purposes. In order, therefore, to entirely relieve the rollers from the force of the driver and to enable a carriage to rest flat and solidly upon the bed-plate, the rollers have their hearings in suitable blocks 12, suspended from the free ends of the spring-bar 13, supported by and above the plane of the table by adjustable bolts 14, screwed into the carriage through slots 15, in which carriage the rollers project so as to rest upon the bed-plate of the carriage. These spring-bars 13 are of sufficient tension and stiffness to resist the combined weight of the carriage, the pot, and the tub, so as to lift the carriage above the bed plate and to permit the rollers to support the carriage thereon, which they do at all times, except during-the descent of the driver upon the staves, and therefore permit the carriage to freely move back and forth over the bedplate with the least possible amount of friction. With the carriage under the driver the force of the driver on the ends of the staves overcomes the resistance of the spring-bars13 and as a result forces the carriage flat upon its bed-plate; but the moment the pressure of the driver is removed the table is lifted free from the bed-plate by the spring-bars and entirely supported upon its anti-friction rollers. Should the spring-bar be bent after frequent operation so as to lose its power to lift the carriage, this loss of power may be compensated for by lowering the screw-bolts 14 and with them the spring-bar, the bolts being locked in whatever position they may be adjusted by means of the lock-nuts 16. (Clearly shown in Fig. 5.) v

To cause the back-and-forth movement of the carriage L, it is provided at its rearward end with a lug 17, connected by a link 18 with a rocking lever 19,fnlcrumed on a pivot 20 in the frame of the machine, as shown in Fig.2, the upper and short arm of which lever terminates in a T, as shown in Fig. 9, the free ends 21 of which T project into a two-part angular camway 22, formed in the inner faceplates 23, between which plates the lever 19 projects. The camway-plates 23 are cast or otherwise secured to the face-plate 24, in turn adjustably secured to the block I of the driver by bolts 25, (see Fig. 1,) projected through elongated slots 26 and screwed into the block I, the face-plate 24, and the camway, being vertically adjustable and locked in that adjustment by bolts 27, the upper one of which has its head resting upon the block I, with its screw-threaded end working in a lug projecting from the face-plate 24;, the lower screw-bolt 27 working in a corresponding lug in the face-plate 24, with its end abutting against the under side of the block I,as shown.

To vertically adjust the camway, the bolts 25 are first loosened, and after turning the bolts 27 to get the desired adjustment the bolts 25 are then tightened, thereby operating, in conjunction with the bolts 2", to lock the camway in whatever adjustment it may be given. This adjustment of the camway is important in that it provides for timing the movements of the tub according to the stroke of the driver, when the latter is changed to adapt it for trussing tubs of different heights, for under all conditions the tub must come to a center beneath the driver before the latter engages the staves and must remain in that position until the trussing operation is com pleted and the driver disengaged from the staves, and obviously in trussing tubs of differingheights the range ofaction of the driver ntust be changed according to the height of the tub, and the position of the cam must be correspondingly'changed in order to produce the desired result.

In operation when the driver is at the limit of its upward stroke, as illustrated in Fig. 1, the end of the rocking lever 19 is near the lower end of the camway 22, and the carriage is at the limit of its backward or outer movement in position to receive or to have removed therefrom a tub. As the driver descends to perform the trussing operation, the eamway descends with it, and in so doing the oblique portion of the eamway actuates the rocking lever so as to swing it to its opposite extreme position illustrated in Fig. 2, drawing the carriage forward into the machine, and centering the tub under the driver, the forward movement of the carriage and tub ceasing immediately the T end of the lever enters the vertical portion of the camway, and it is not until the tub is so centered that the gathererof the driver is in contact with the staves of the tub. The further descent of thedriver and camway in completing the trussing operation has no effect upon the tub, which remains at rest during such movement because of the working of the T on the lever in the vertical portion of the camway; and it will thus be seen that the tub will remain at rest during the entire trussing operation, and that it is not until after the driver has cleared the slaves on its return or upward movement that the inclined portion of the camway causes the rocking lever 19 to again swing on'its fulcrum and move the carriage with the pot and trussed tub out from under the driver back to the position shown in Fig. 1 for the removal of the tub and theinsertion of a new one to be trussed. It will therefore be understood that while the stroke of the driver and the camway is always the same therange of its action varies materially, according to the height of the tub to be trussed, the position or range of action of the driver and camway being readily changed by means of the turnbuckles in the crank-rods II, and the position of the camway with relation to the driver must be changed accordingly, so that the carriage may be moved in time with the driver, being lowered when the driver is raised for the trussing of the higher tubs, and raised when the carriage is lowered for the trussingof thelower or shorter tubs. The lever 10 is also shown as provided with laterally-adjustable bearings; but this feature is simply for convenience in putting the parts together, and has no other duty to perform after the parts are once adjusted and secured in place.

The connections between the movable carriage, as shown, while of the preferred form and found successful in practical operation, may be of other forms and arrangements, without departing from the spirit of our invention, which includes, broadly, any connection between the carriage and the driver or any other portion of the machine by which the table may have the movements described, and also in a more limited sense, by which the action of the driver causes the table to move in proper time therewith to center and truss the tub and discharge it from the machine, as has been described.

In the practical operation of the machine a slight interval is required in which to remove the trussed tub from the pot and insert a new one, and in order to save time and avoid the danger of breakage of anyof the parts of the machine, a result of the carelessness of the operator, we have preferred to make a stoppage of the machine after each trussing operation automatic by some suitable meanssuch as the ordinary hand-lever D'pivoted at D to a suitable projection or fixed portion of the machine, and having at its forward end a yoke D engaging and operating. the clutch D, while the opposite or free end of the lever works through and is guided in a slotted bracket or projection D. This lever is normally actuated to throw the clutch out of engagement by a coil-spring a on the rod 1), pivotally connected to theleverD, near the other end thereof, and working in a sockct-piece c, between which socket-piece and a shoulder or collar (Z on the rod the spring is confined.

Near the free end of the hand-lever D is rigidly secured one end of a stop-bar 0, provided with an inclined lug c, adapted and arranged to be engaged by a crank-arm f on the rocking shaft f, journaled in suitable bearings secured to the frame of the machine, to the oppositeinuer end of which shaft (see Figs. 2, 7, and S) is secured another crank-arm f which for clearuess is designated as a stoparm and which projects downwardly into the path of a laterally-projecting lug or shoulder f on the carriage L. Therocking shaft f is IIO actuated in one direction by means of a coil spring f secured at its ends, respectively, to the free end of the stop-arm and the frame of the machine, so as to cause the crank-arm fon the opposite end of the shaft to normally bear against and engage thelug or stop upon the stop-bar (2; but when the carriage is moved to the limit of its backward stroke that is, to the position shown in Fig. 7the lug or shoulder f thereon strikes against the stop-armf so as to overcome the tension of the springf, rock the shaftf' in the opposite direction, and free the armffrom the lug on the stop-bar, which latter device operates as a latch.

\Vith the parts in the position shown in Fig. 7, to start the machine the operator pulls the hand-lever inwardly against the tension of the spring a, thus throwing the clutch D into engagement, and starts the machineinto operation, holding the lever for an instant in this position until the carriage slides forward sufficiently to let the spring f operate the rock-shaft, and cause the engagement of the crank-arm f with the latch 6, when the clutch will be carried into engagement. The parts will remain in this position untilthe carriage has moved forward, the trussing operation has been completed, and the carriage returned to its first position, just before reaching which the lug f thereon strikes the stoparm f on the rock-shaft, and causes the disengagement of the crank-arm f with the latch, when the spring a will throw the lever outward, and thus disengage the clutch and instantly arrest the operation of the machine.

"IVhile answering every purpose in practice, we do not desire to limit ourselves to this form of connection between the throw-otf lever D and the carriage; but it would be no departure from the spirit of our invention to use any other form of stop connection answering the same purpose, many of which are well-known to those skilled in the arts.

In order to relieve the various parts of the machine from strain, we have also provided stop devices for limiting the inward or forward movement of the carriage, which stop devices, as illustrated in the drawings, practically consist of a piston or plunger device confining a yielding packing, such as that illustrated in Fig. 3, consisting of the socketied brackets g, secured to the bed plate M at each side of the machine, in the socket of each of which is secured a rubber ring or gasket g, through which passes the stem of a piston g into which is screwed an adjustable stop-bolt g, which is locked in its adjustment byanut g, which provides for taking up the wear of the yielding packing and of the other parts of the machine and also serves to cushion the carriage when it strikes against the seat. The stem of the piston may be held against withdrawal from the bracket by any suitable means, as by the collar and set-screw shown in Fig. 3.

Vhile our machine has been described and illustrated in its use upon butter-tubs, it is obvious that it is equally applicable to machines for trussing barrels, kegs, and other devices, for obviously no change in the machine is required for such purposes other than dimensions and form of pot best adapted for the particular article to be trussed; and, furthermore, we do not recognize that there is any substantial distinction in the character of the operation required for trussiug butter tubs as compared with trussing barrels, kegs, and bucket-like structures.
