IMPROVEMENT IN BINDING ATTACHMENTS 'I'O HARVES'I'ERS.

Specification forming part of Letters Patent No. 22,074, dated November 16, 1858.

the following is a full, clear, and exact de-- scription of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a longitudinal section at a: 0:,

. Fig. 3. Fig. 2 is a transverse section at y 3 Fig. 3. Fig. 3 is a top view, the platform and a portion of the flooring being removed. Fig. 4 is a perspective View of the front part of the machine, the front fioorin g being removed.

The accompanying drawings represent a machine embodying my improvement, and adapted for attachment to a self-raking harvestersuch, for instance, as that patented to J earum Atkins, December 21, 1852.

Thisinvention consists in an arrangement of means, substantially as hereinafter described, for the automatic binding of grain with a portion of its own straw.

A is a bed or frame, supported on customary ground-wheels B B G, of which the wheel B is the driving-wheel. Resting on the bed A is an inclosing-box, D, whose top is floored, E E, at each end. The interval between the floor E and the floor E is occupied by a platform, F.

The platform F has a hinged attachment to a bar, G, which bar is the first of a connected series of compound levers, G H I J, having their fulcra at g h i j, respectively.

The rear end of the last lever, J, affords journal-bearing to a shaft, K, near its right end, the left end of the shaft K journaling in a stationary bracket, L.

The right or yielding end of the shaft K has a spur-wheel, M, which, in its normal or upper position, is unaffected by the advance of the machinealong the ground; but which, when the platform. F is depressed by a charge of grain, sinks into gear with a spur-wheel, N, at the back of the driving-wheel B, so as to be rotated by the latter.

0 is a spring, which restores the levers G H I J, spur-wheel M, and platform F to their upper or normal position the instant that the platform is relieved of its load.

Near the ,mid-length of the shaft K is a segmental bevel-wheel, P, which gears to a smaller bevel-wheel, Q, on one end of a shaft, R, whose other end has a similar bevel-wheel,

S, which gears to an inverted crown-wheel,

T, on an upright shaft, U, which shaft is surmounted by a fixed jaw, V, and a hinged jaw, W.

X is a fixed horizontal bracket, having a round hole, through which the shaft U rises. This hole, being eccentric with the shaft U, causes the loose jaw to close against the other by the rotation of the said shaft. The shaft U, jaws V, WV, and bracket X, I call, collect ively, the pliers I I.

The left end of the shaft K has a spurwheel, Y, which gears to a similar wheel, Z, on a horizontal shaft, z, immediately over the shaft K. The shaft 2 has, near its mid-length, a cam, a, whose rotation pushes forward, at the proper moment, a yoke, b, armed with a rod, 0. d are eyes which serve to guide the rod 0. c is a spring, which retracts the rod when released by the cam. f is a segmental spur-wheel, mounted on the right end of the shaft z, for purposes hereafter explained.

The spur-\vheelY has around half its circumference a set of bevel-cogs, g, which gear "to a pinion, it, on a shaft, 1, which shaft has two cranks, m a, connected, by pitmen, 0 p, to levers q r, to whose upper ends are hinged, respectively, two rods, 8 t, whose free ends rest in guides to e, and are notched, as shown. These rods 1 term, respectively, the looper s and the tucker-in t.

A standard, 1, which rises vertically from the floor E, has projecting horizontally from it journal-boxes 2 4, for a sliding and revolving stem or post, 3 3, whose lower enlarged portion, 3, is grooved to receive a lozenge-shaped lug, 6, projecting from a fixed semicircular yoke, 7, which incloses and guides the stem at this part. The lower part, 3, of the stem, called by me the barrel, has a rack, 8, which gears to the segmental spur- Wheel f, before mentioned.

9 is a collar on the stem 3. 10 is a spiral spring, which, extending from the box 4 to the collar 9, serves to restore and hold the stem and its appendages to their upper or normal position when released by the wheel f.

A bracket, 11,journaled to the upper part of the stem B, is provided with two journalboxes, 12, which support a horizontal shaft,

' 13, which is mounted at each end with a bevel cog-wheel, gearing with corresponding wheels attached, respectively, to the stem 3 and to a vertical shaft, 14, which is also journaled in boxes supported by the bracket 11.

The stem 3 3, bracket 11, and their accessories I style, collectively, the crane, I I I.

15 is an ellipticalv spring, attached at its upper side to the shaft 14, and connected at its, lower side with two curved arms, 16 16, which have notched extremities, called by me the talons. Each talon is composed of a fixed spur, 17 17, and an adjustable spur, 18 18.

The platform F has an H-formed perforation, 19, to admit the passage through it of these talons, and of the band or wisp of straw, as hereafter set forth.

20 is a heel projecting from the bracket 11, and which,by striking the standard 1, arrests, at the proper instant, the forward swing of the bracket, so as to cause the remaining rotation of the stem to be expended in rotating the talons, as hereafter explained.

This machine may be so modified as to be applicable to other descriptions of harvesters.

The operation is as follows: The front part (marked with an asterisk in Fig. 4) being suitably attached in the rear of an Atkins or other self-raker, in such position that the gavel will be deposited on the platform transversely to the machine, such deposition ot the gavel brings, as before explained, the operative parts into connection with the drivingwheel, the result of which is, that the crane, actuated through its rack 8, and confined to a specific path by the lug 6 in the groove 5, descends in a right-hand spiral direction until its talons are inserted in the gavel so as to fill their crotches with straw. Then, the gyration of the crane-bracket 11 being arrested by the impingement of the heel 20 against the standard 1, the motion of the stem 3 3 is communicated, through the shafts 13 and 14, to the arms 16 16, so as to place the latter astride of and pressing down upon the gavel, carrying with them a wisp of straw through the aperture 19 in the platform, and

so that the ends of the wisp are introduced bundle, and also to twist the ends of the wisp together. I

The rod 0 then advances in front of the twisted wisp, so that the forward motion of the looper S forms a loop, which is then taken by the tucker-in t, and the pliers V W, at this instant releasing their hold of the ends of the band, the latter are tucked'beneath the band in a similar manner to that performed by hand. Meantime the ascent of the crane has drawn the arms 16 16 up through the platform F, and the crane swinging back, this action causes the now bound sheaf to be swept off the platform by the arms 16 16, and the machine is then ready for another gavel.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The arrangement of gravitating-platform F 19 and series of leversG H I J, with their accessories, in the described connection with a drive-wheel, for the automatic starting of the binding mechanism by the weight of the sheaf or gavel, substantially as set forth.

2. In this connection, the talons 16 17 18 16 17 18, constructed and operating substa-ntially as set forth.

3. In combination with the talons or their equivalent, the crane I I I and its accessories, having the described compound movement, substantially as and for the purpose set forth.

4. In the described combination with the talons or their equivalent, the pliers I I, constructed and operating substantially as set forth.

5. The rod 0, looper s, and tucker-in t, constructed, operated, and operating together substantially as set forth.
