To all whom it may concern.-

Be it known that we, JAMES A. GRAHAM and EDWARD J. .BIRKETT, citizens of the have invented certain new and useful Improvements in Grain-Binders; and we'do hereby declare that the following is a full, clear, and exact description of the invention,which will enable othersskilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. Our invention relates to that class of automatic grain binders in which the grain as it is delivered into the binder is by the action of the packers formed into a gavel against a yielding compressor arm which, when a sufficient amount of grain'for a gavel has been accumulated, yields and trips the binding mechanism into gear, and thereupon the needle arm advancing compresses the grain against the compressor arm and places the twine in the knotter, which ties and discharges the' bundle.

Our improvements consist essentially, first, in the'construction and arrangement of the binder frame and gearing for'operating the binding mechanism; and, second,in the compressing and tripping mechanism for automatically starting and stopping the binder at the proper times.

They consist also in certain other novel features of construction and arrangement hereinafter particularly described and pointed out in the claims.

In the accompanying drawings, like letters designate the same parts in the several views.

Figure 1 is a rear end elevation of a portion of a grain binder to which our improvements are applied. Fig. 2 is a face view of parts being shown in the position they occupy when the binder is at rest. Fig. 7 is a sectional view'on the line y 3 Fig. 6 of aportionof the binder. Fig. 8 is an end view of the driving pinion on the rear end of the packer shaft, a portion being cut away to expose its ratchet connection with said shaft. Fig. 9 is an enlarged rear end view of a portion of the binder, a part of the trip lever and gear on the knotter shaft being broken away to disclose parts which would otherwise be hidden thereby. Fig. 10 is a view like that shown in Fig. 9, except that the gearwheel is removed. Figxll is a perspective view of our improved binder; and Fig. 12 is a side elevation of the yielding compressor yoke on the lower arm of the binder frame, which is shown in section. Fig. 13 is a perspective view of a portion of arm a of the binder frame, showing the arm a projecting therefrom, and which supports the forward end 0 the compressor.

A represents the upright portion of the binder frame, formed with two parallel tubular arms a and a. projecting horizontally therefrom; the former carrying the knotter shaft D and the latter the needle shaft 9 The upper end of part A, at or near its junction with arm a, is formed into a housing as shown in Figs. 7 and 10 for inclosing and shielding a. part of the trip and compressor connections. It is also formed near its upper end with a bearing for the upper end of shaft 0, and below said bearing it is made tubular or hollow for the purpose of inclosing said shaft. Fitted into its lower end and secured therein by a set screw 5 isabox b, carrying the lower end of shaft 0, and formed at right angles thereto with a box b carrying the rear end of shaft B; said boxes being so formed as to constitute a housing for the inter-working pinionscand c; the former mounted loosely upon and connected by a ratchet with shaft B, and the latter secured to the lower end of shaft 0.

B is a continuously rotating driving shaft, which may be driven from any convenient part of the machine. It is provided at its front end with cranks for operating the packers g g, and is supported in the box biabove pinion c for intermitti-ngly actuating vthebinding mechanism, as he eina t te p -Mounted upon the rear end of knotter shaft D is a mutilated bevel geard arranged to work withthe pinion 0 The number o f teeth left out of gear din thisinstanee is three, but it is evident that the number should be varied according to the size of said pinion.

An outwardly or laterally yielding sector d, provided with the requisite number of teeth.

to fill the break in said gear, is pivoted thereto by a bolt d and held in working position by a sprin g d? interposed betweenit and an overthe upper end of pitman g, which is connected at its lower end with a crankarm g on the rear end of needle shaft 9- carrying at its front end the needle G in the usual manner. 7

Fisthe trip a d compressor shaft, supported at the rear end by a 1 oral-m s q jecting from the" binder frame and at the 1 front end by a yielding yoke J, which is formed with two or more notc es 0r bearings to e eive said shaft, as shown in Figsll and 12,-for regulatingthe size of the gavels. Upon the front end 01; shaft 13 is mounted the tr p to compress the gavel.

The overhang- 7 Upon the rearendof :v sha t F is secu ed the crank arm f which is I Cam E is limited in its: movement in. th directions by lugs e and; e coming iucontact with the inside of the,

'binder frame, as clearly shown in Fig. 10, resists the yielding of the compressor arm f and holds said dog in engagement with a lug d on the rim of gear (I. It is evident that separate springs may be used for these purposes, but we prefer in practice the single spring, wh ch, when arranged as shown and described, insures the return of the trip lever H to its normal position after a bundle is discharged, the lug d passing under the roller in the end of dog h and compressing saidspring just as said lever is brought home.

The yoke J is formed with an, elongated transverse opening by which it is mounted and permitted to move in the direction of its length upon the lower arm a of the binder frame. It is guided and held in place between an outwardly projecting arm a on the binder frame and la flang e on the hub of the needle arm and is, formed with a g oove j, shown in Fig. 12, which engages with the front edge of said arm a as shown in Figll. Yoke 3 extends inwardly from arm a and is 'formed into a receptacle .for a coiled 1 grain.

As thegea wheel dcontinues to revolve, the roller'h' drops into the depr s-' sion at in said cam, thus permitting the compressor arm f too tall .suiilciently to'all w the discharge of t e bundle from the bin e The roller h passing-out of the depression (i a ses said compressor a m fto its normal upright position, and at the completion of the revolution of gear-d drops intoits, seat 01 in cam d". As theege'ar d completes its revolution; itcarries arm d5 of sectorv .df into contact with trip cam E, and thereby th-rows said sector out of engagement with the" continuously rotating pinion c; The projection upon the lower end of sector (1 thereupon en-' gages with lug a on the binder frame, as shown in Fig. 9, and stops the binding mechanism; at the same time the locking dog It drops back of lug cl on gear d, and is held in place by the spring 6 thus preventing a backward movement of said gear. By reference to Figs. 6, 9 and 10, it will be observed that the dog 72 is formed with a stop at its free end, which engaging with a lug h on the binder frame supports the dog in the proper position for carrying spring a as shown, and holds the roller. in said dog out of contact with the rim of gear (1, except when it engages the lug d", as hereinbefore mentioned. The binding mechanism now remains quiescent until it is again set in motion in the manner hereinbefore described, by the formation of another gavel.

We do not wish to be understood as limiting ourselves to the exact construction and arrangement of parts herein shown and described, as it is evident that many changes may be made without departing from the spirit of our invention.
