TRIPPIN G MECHANISM FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 630,853, dated August 15, 1899. Application filed April 27, 1898. Serial lio. 678,961. (No model.)

To all whom it may concern:

Be it known that I, OHRIsToPH O. BREU- soHER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tripping Mechanism for Grain-Binders, of which the following is a specification.

My inventionrelates to certain improvementsin tripping mechanisms for grain-binders, and especially to that class of tripping mechanisms in which a clutchis employed to connect the continuously-rotating packershaft with the intermittently-rotating binding mechanism. This clutch is controlled by the presser-arm, against which the forming gavel is compressed until the pressure of the gavel serves to operate the clutch mechanism and cause the binding mechanism to come into operation and bind the gavel.

My invention relates more specifically to the trip-stop, which is mounted upon the trip rock-shaft carrying the presser-arm and which cooperates with the trip-arm upon the afore-' said clutch and is concerned mainly with making said trip-stop adjustable in two directions-4. 6., longitudinally and vertically.

My invention is an improvement upon that shown in my application for a patent, Serial No. 660,942, filed December ti, 1897. In the description and drawings I have shown and described only so much of the mechanism as is necessary to make a disclosure of the operation of my improvements, the general construction and operation of these tripping mechanisms being well known to those skilled in the art.

In the accompanying sheets of drawings, in which the same letters of reference are used to designate identical parts in all the views, Figure 1 is a plan view of a portion of the binding mechanism with some of the parts omitted and with others broken away. Fig. 2 is a side elevation of the same mechanism in section on the line 2 2 of Fig. 1, with some of the parts omitted to more clearly disclose the construction. Figs. 3 and 4: are a side elevation and plan view, respectively of the trip-stop proper, showing the adjustments. Figs. 5 and 6 are similar views of a preferred form of the trip-stop; and Fig. '7 is a view which are the oppositely-disposed shoulders M, with which the clutch member (generally designated by the letter J) engages to connect the clutch-plateL with the clutch-block M. This clutch-plate L on which the clutch member J is pivotally mounted is fastened to the left-hand end of the sleeve a, mounted upon the bearing-rod C6. The right-hand end of this sleeve a carries the gear-pinion a which meshes with the internally-toothed gearwheel E, rigidly mounted upon the binder drive-shaft E. This wheel or disk E carries upon its right-hand face the guide or controlling flange e, withwhich cooperates the friction-roller f, carried by the crank-arm F, rigidly mounted upon the trip rock-shaft d, which is suitably j ournaled in bearings and extends parallel to the shaft A. In addition to the crank-arm F, mounted upon its righthand end, this trip rock-shaft D has rigidly fastened to its left-hand end the crank-arm d, to which is pivotally attached the arm D, which is mounted, as seen, so as to be capable of swinging very slightly against the stress of the strong coiled spring D without aifecting the crank-arm d, and thereby rocking the trip rock-shaft (Z. Upon this same shaft (1 and between the crank-arms cl and F is mounted the trip-stop H, which is substan tially in the plane of the clutch member J, with which it cooperates. At. its outer end this trip-stop H has a lug 7L, projecting into the plane of the lug which is customarily in the form of an antifriction-roller, carried by the straight arm of the clutch member J. This clutch member comprises also the arm 7' carrying the antifriction-roller j which cotending to hold the autifriction-roller J3 in engagement with one of the shoulders M on the clutch-block M, so that the sleeve a shall be engaged to the packer-shaft A, so as to rotate therewith. WVhen the antifriction-roller j is engaged by the lug h, as set out below, the clutch member J is rocked, so as to disengage the antifriction-roller 3' from the shoulders of the clutch-block M, and thereby the sleeve a is un'clutched from the packershaft A and held from rotation.

As previously constructed prior to my invention, especially as shown in my application Serial No. 660,942, above referred to, the trip-stop H has been made adjustable about the shaft d, so as to be capable of angular movement relative thereto and, so far as the operative position of the stop is concerned, capable of what may be termed vertical adjustment. In the operation of the device, as set out below, there is a considerable amount of hammering and friction between the lugs h and j, so that in course of time,

owing to the natural wear of the parts and other causes, the relative positions of the lugs h and 7, which depend upon .the relations of a number of mechanisms, are likely to vary,

. and as a consequence the trip-stop fails to act in the desired manner. In order to overcome this difiiculty, the adjustment of the trip-stop shown in my aforesaid application was made; but, as before stated, owing to the form of mounting employed it was only capable of angular movement about the shaft d, or what may be called a vertical adjustment, In order to enable me to get a perfect adjustment of the trip-stop, it is necessary to provide means for what may be called a longitudinal adjustmentthat is, an adjustment whereby the distance of the lug h from the shaft cl may be changed as may be necessary to secure the required operative relation between the lugs h and j. While I might make these two adj nstments separate and independent-i. 6., construct the trip-stop so as to be capable of a vertical adjustment independent of any longitudinal adjustment or of a longitudinal adjustment independent of any vertical adj ustmentI prefer to so construct the adjustments that as the trip-stop is adjusted longitudinally it shall at the same time be adjusted vertically, so as to keep the lugs 72 and j in their proper relative operative positions. To secure this mode of operation, I employ the constructions to be described.

Referring especially to Figs. 3 and 4, I secure to the shaft d a hub P integral therewith or fixed thereto by any suitable means, as by a rivet p. The hub P is provided with two lugs Q and Q, arranged at substantially right angles to each other. The trip-stop H is formed with a longitudinal slot q, adapted to S, which passes through a second longitudinal slot q in the stop H, the bolt S carrying a nut s, by which the trip-stop may be secured in any desired position. The adj usting-screw T is set in the rearward end of the trip-arm H, extending through the arm and into the slot q, so that it may bear against the lug Q. A jam-nut 75, mounted upon the bolt T, serves to effectually lock this bolt against rotation.

of the trip-stop H, and which in their intersection form an obtuse angle which is substantially complemental to the rentrant angle formed on the under surface of thelug Q.

From the full and dotted line positions shown in Fig. 3 it will be seen that as the trip-stop H is adjusted longitudinallyit will be given a certain vertical adjustment, and vice versa, the adj usting-surfaces being so arranged as to simultaneously furnish the exact Vertical adjustment which is essential to the change in the position of the lug h made by the longitudinal adjustment.

In Figs. 5 and 6 I show a preferred form of bearing-surfacesbetween the lug Q and the trip-stop H, the change being that in place of having the two angularly-disposed bearingsurfaces on each member I increase-these bearing-surfaces to an infinite number, soas to produce the complemental curves Q and H which, as will be readily seen, operate on exactly the same principle as do the bearingsurfaces of the construction shown in Figs. 3

and 4, and these curves, the same as the angularly-disposed surfaces, can readilybedesigned so as to simultaneously secure the relative vertical adjustment necessary in connection with any longitudinal adjustment to maintain the lug h in its proper operative position relative to the lug or antifriction rollerj.

In the operation of my improved tripping mechanism the normal position of the parts is with the antifriction-roller f resting against the hook e of the piece 6 which is pivoted to the under surface of the flange E, as at e and which is normally held outward by the compression-spring e carried upon and secured by the bolt 6 fastened to the flange 6. These parts last referred to are conveniently shown in Fig. 2 in dotted lines. In this positionof the controlling crank-arm F the lug h of the trip-stop H is directly in the path of the lug j of the clutch member, and the engagement of these lugs h and j serves to hold the antifric tion-rollerj out of engagement with the shoulders M of the clutch-block M, and thus the sleeve a is held from rotation with the packershaft A, and the wheel or disk E and its binding-shaft E are held motionless. The pressure of the forming gavel is transmitted to the presser-arm D, and when the gavel is sufficiently large the pressure thereof overcomes the resistance of the spring 6 and the hook e yielding inward the controlling crank-arm F is also permitted to swing inward, and its movement rocks the shaft d until the tripstop II is moved sufficiently to disengage its lug h from the lugj of the clutch member. As soon as this disengagement is eitected the spring 0 throws the clutch member so as to connect the clutch-block M and the clutch-plate L, and the wheel or disk is rotated by the ensuing rotation of the sleeve a. In the construction shown it requires three rotations of the gearpinion (b to rotate the disk E once, and during the first two rotations of the pinion or the first two-thirds of the rotation of the disk E the pressure of the gavel holds the antifriction-rollerf upon the flange 6, thus holding the lug h of the trip-stop H out of the path of the lugj of the clutch member J, this position being shown in the dotted-line position of the trip-stop in Fig. 2. During the third rotation of the pinion (t the flange e not being present at the portion of the periphery of the wheel adjacent to the antifriction-wheelf at this period,the gavel,which has been bound, is discharged, the absence of the flange e at this point permit-ting the controlling crankarm F to swing inwardly to allow the presserarm I) to swin down to permit the discharge of the gavel. At the close of the complete revolution of the disk E the antifriction-roller f of the controlling crank-arm is engaged by the hook eof the flange E, and the trip rockshaft (Z and its associated parts are once more swung into their normal position, in which the lug It, being in the path of the lugj, serves to disconnect the clutch and stop the operation of the binding mechanism until another gavel is formed.

It will be understood that my invention is capable of some modifications, and that I do not desire to be limited to the exact structure shown and described; but
