IMPROVEMENT IN COMBINED HAY-RAKE ANb TEDDER.

' The Schedule referred to in these Letters Patent and making part 01 the same.

Nature and Objects of the Invention.

My improved combined hay-rake and tedder is a wheel-implement, and of the class which is adapted for different uses by the reception merely of the proper heads, thus saving the expense, 850., of separate implements, or even separate sets of operating devices or frames.

My improvements relate to the adaptation of the operating devices, without complication of parts, to impart to the head an intermittent or continuous rotary movement, as required, and to the more perfect resenting itas adapted for employment as a rake, and a the head in its elevated position.

The teddcr-head is shown in dotted lines in both figures,'and the working position of the head also thus indicated in fig. 2.

Figures 3, 4, and 5 are sectional perspective views of parts of the operating mechanism, detached.

Figure 6 is a sectional perspective view of a portion of the rake-head, illustrating the construction of its teeth.

Similar marks of reference indicate like parts in the several figures.

General Description.

The frame A of the machine is mounted on a pair of ground-wheels, B B, the axle O of which forms' a part'of it. It is thus pivoted.

The shafts or t-hills D, or their equivalent, are hinged, d, to the axle U, and are utilized besides, for the attachment of draft, to provide bearings for a transverse rock-shaft, E, for adjusting, by means of cams e thereon, the-position of the frame.

Said rock-shaft is actuated by meansoi' a lever, E, projecting through a slot, (1, in the floor of the frame A, (when such fioor exists.)

Its cams e, which may be two in number, are in the form of tangentiatrglrved arms, and work in staples or brackets a, on the under side of the fi'ame A.

Runners F, at the rear end of the frame, support the same at the proper working-height, when do pressed, and automatically elevate and depress it, to

accommodate it to irregularities in the surface.

The head G (tedderor rake) is mounted at the rear end of theframe, being supported by a pair of shafts,

H, mount-ed in liuetransversely of the side bars of the frame, in suitable boxes, I, and provided, at their in- .ner ends, with sockets, h, for the reception of the ends of the heads. I

Said shafts, one or both, are further provided, at their outer ends, with pulleys, K, for the reception of motion, through bands L, (preferably cl1ains,) from pulleys, M, formed on'or attached to the sides of the ground-wheels, to revolve the head, and intermediate] y with locking-disks 0r collars, N, by which to hold the head from rotation when desired, as while raking, be ing engaged by rolling tumblers or stops 0, for this purpose.

The pulleys K are preferably (as shown) mounted loosely on the shafts H, being supported laterally by heads h, and connected to the shafts by ratchet couplings S, the respective members, s s, of which may be formed on them and on the disks or collars N, as shown, the latter being connected to the shafts by spine or similar joints, and engaged by the shiftingforks T,'being for their engagement provided with 011'- cumferent-ial grooves 1. r

Springs U, which may be interposed between the heads h of the shafts and the pulleys, afford the requisite yielding support to enable the couplings to automatically disengage on any obstruction being met in a backward movement.

The locking-disks or collars N may each support one of the parts of the couplings S, as above described, or may be solid with the shafts or rigidlyattached thereto, the couplings being separate. The proposed construction of said collars is clearly shown in figs. 3 and 4 of the drawing.

Shoulders, 2, are presented on their inner surfaces for the engagement of the stops 0, and sufficient space in front of said shoulders is provided to permit the bolts to be thrown into position during the rotation of the shafts.

The flanges a, which provide the shoulders 2 and occupy the space not required to permit the engagement of'the stops, serve to prevent such engagement of thestops as would result in the premature uncoupling of the driving-pulleys when the implement is being used as a rake, said stops being adapted to govern the operation of the pulleyecouplings, as hereinafter set forth.

Bearings for the stops 0 are provided in the boxes I of the shafts.

Said stops are provided with arms 0, by which to oscillate them, which arms, working in slots, i, in their bearings, serve also to support them longitudinally therein, said slots serving further as stops to regulate 0 determine their movement. They are arranged about .half way within the circumference of the locking-collars N, and their engaging faces, 3, being in about the planes of their axes, they are adapted to present the. necessary abutments for engagement, as,

represented in fig. 3, and, by being given about a onefourth revolution to withdraw said abutting surfaces, and permit the rotation of the head.

. The forks T, in the form of horizontal bell-cranks,

are pivoted to brackets projecting laterally from the boxes I, and projecting over the same, are provided,

at their free ends, with wrists t, about in line with the arms 0 of the stops 0, by which to operate them.-

The stops 0 and'forks T are actuated through rods 4 P, attached to the arms Q of the former positively at forced backward to lock the head and uncouple the diiving'mechanism by a suitably-applied spring, R, an extension, 4, of the socket Q, forming a treadle by which to force said socket forward to reverse the condition of said parts. 7 4

Slots t, in the ends of the boxes I, for the reception of their attaching-screws, enable their adjustment to bring them in line, 85c.

The heads G, of which separate ones are employed, are provided, respectively, with rake-teeth g and tedder-teeth g. They are otherwise of similar construction. They may be secured in the'sockets h of their operating shafts by transverse screws .or other suitable means. p

The teeth g of the rake-head G g are provided with the customary coils at their upper ends, to impart the necessary springiness. Their stubs, 6, however, arecarried up between the coils, as .represented most clearly in fig. 6 of the drawings, instead of on one side, as is usual, and thus combine the spring of the double coil with the lateral support of the single coil.

. The teeth g of the tedder-head G g are secured in the head proper, which is a single shaft, and project tangentially therefrom. They are so bent that their ends are radial to the head or project behind such radial lines. Above they have a compound reverse curve, which serves to throw the hay outward to the ends, by which it is discharged at an angledetermined by the degree of rearwardprojection of the said point.

A drivers seat and suitable means for holding the lever E and treadle Q q may be provided onthe frame in suitable position.

. The formand arrangement of the several parts, except where function depends on them, are variable. Other modifications may also be made, for instance, one set of driving and holding devices, or of .one or the other, might be dispensed with in some machines.

Operation.

In use, the proper head being applied, and, if necessary, brought into line by adjustingthe boxes'I of its shafts, the machine is run into the field with its frame in the position represented in full lines .in fig. 2 of the drawing, and has the same then adjusted to the position indicated-in dotted lines in said figure, .by the lever E and media E e a, or their equivalent, the runners F resting on the ground, and the head supported thereby at proper working height, when the operation may commence.

.For teddering, the head G 9 being attached through the medium of the devices Q q R Q P4 5 T t S 1 o, the stops 0 are withdrawn and the pulleys K connected to theshafts of the head, when, the machine being started, the requisite rapid continuous rotary motion will be imparted to the head through said pulleys and the bands I, from the pulleys M on thegronndwheels. 7

For raking, the head G 9 being attached, the machine is started with the couplings and stops in their normal condition. On the teeth being filled, the treadlc Q is pressed on with the foot, actuating successively the stop 0 and the coupling S, releasing'the its load. The treadle, having been meanwhile released,

malcondition. The assumption of this, however, is deferred untilv the necessary portion of the rotation has been positively imparted to insure its completion by the flanges n of the locking-collars N, arresting the movement of the stops, and, consequently, (owing to the positive connection of said stops with the operatthe couplings of the operating pulleys. On the completion of the rotation thehead is again locked by the shoulders 2 of the locking collars N on its shafts comof the opera-ting pulley.

Thus the operation continues:

In both uses the runners, F serve to support the head at the proper height and to accommodate it to irregularities in the surface of the ground. In running back, the couplings of the operating pulleys are automatically uncoupled, owing to the ratchet-form of the-engaging-teeth of said coupling, and the yielding support afforded by' the springs U.

Claims. I claim, as my inventionin the manner described, for the purhaving their attaching stubs 6 carried up between the coils, in order to support them laterally, as described.
