Specification forming part of Letters Patent No. 18,188, dated September 15, 1857.

To all whom it may concern.-

Be it known that I, A. H. CARYL, of Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Raking Attachments for Reaping- Machines, of which the following is -a full, clear, and exact description, reference being had to the accompanyingdrawiugs, making part of this'specification, in which- Figure 1 is aview of areaping-machine with my improyed rake attached; Fig. 2,a detail of a portion of the rake apparatus; Fig. 3, a section 'on the line A A ofjFig. 2; Fig. 4, a section on the line B B of Fig. 2; Figs. 5, 6, 7, details to be referred to hereinafter.

In the saiddrawings, O is the frame of the machine,which is hung in suitable hearings on the shaft D of the main or driving wheel E. Attach ed to the frame 0, and rising therefrom, are four standards, F, which carry the raking attachment. A brace, G, extends from one of the standards F to another one near the middle of their length. The middle of this brace G is formed into a step, a, fora vertical shaft, H, which has its upper hearing at 1) between the heads of this pair of standards F. Secured to the head of the shaft H is the horizontal shaft I. These shafts are connected in the following manner: A cap, A, fits on the'head of the vertical shaft H, and can be moved up and down on it a short distance, and is secured thereto by a screw. Attached to the top of the cap A, and lying at right angles thereto, is a sleeve, B, into which fits the horizontal shaft I, which can be turned round in the sleeve, and is secured thereto by a pin passing through the sleeve into holes in the shaft. 1

Supported on the heads of the standardsF is a flat bar, L, (see Fig. 2,) to one end of which is connected another bar, K, which extends out from it at right angles toward the rear'part of the machine. The outer ends of these two bars are connected-by the flat circular way M, forming a quadrant. On the outer end of the way M, over where it is attached to the bar K, is secured a short rack-bar, 0. Attached to the other end of the way M is a block or stop, N, Fig. 3, against which the shaft I brings up when swung toward the front of the machine.

A cushion, d, of india-rubber, is attached to the inner edge of the block N to relieve the concussion of the shaft I, and to check. its speed as it is swung round before itstrikes the block the latter has attached to its upper side an adjustable spring-brake, e. to the shaft I, and projecting horizontally therefrom toward the hack of the machine, are two arms, f and 9, one near the end and the other near the middle of the length of the shaft. These arms carry in bearings at their outer ends a smaller shaft, 0, to the outer end of which, beyond the arm f, is attached a cogwheel, h, which engages with a rack, i, on the face of a bar, P, which slides up and down longitudinally in abox, K, attached to the outer end of the shaft 1. The plate to which the rack i is attached projects on each side of the bar 1?, and enters grooves in the side of the box K, as seen in Fig. 2, and serves to steady the motion of the bar. the distance to which the bar 1 shall descend. To the lower end of this bar is attached, by the middle of its length, the rake Q, the longer axis of which is in the same plane as the axis of the shaft I. The pin m is so placed that the points of the rake-teeth may descend to within a very short, distance of the table It, on which the cut grain falls.

On the shaft 0, near its bearing in the arm g, is a roller, l, Figs. 2 and 3, which revolves on the shaft and traverses on the way M. As the shaft I is swung toward the block N the roller lis pressed between the spring-brake c and the way M, and the motion of the shaft is checked before it strikes the block. Alongside of the roller I there is running on the shaft 0 a pinioinwheel, n, Fig. 2, of a little less diameter than the roller, which, as the shaft I is swung toward the back of the machine, rises onto and engages with the short rack c. This pinion a, when traversing the rack 0, toward the outer endot' it, is clutched with the shaft 0 in the following manner:

Secured to the pinion n is a disk, 0, to the outside of which is pivoted a dog, T, which is held by its spring 12 in contact with aratchetwheel q, secured to theend of the shaft 0. By

this arrangement,.as the pinion is revolved, as

above mentioned, it revolves the shaft 0, and through the cog-wheel h and rack t lifts the rake up vertically, or nearly so, clear of the grain. When the pinion n has reached the Secured A pin, m, regulates outer end of the rack c, and the shaft I, with its attachments, is required to be swung back again, as will be hereinafter explained, the ratchet-wheel qis held by the dog t, pivoted at b to a short standard, '10, attached to the shaft 1', Fig. 4., a spring, a, attached to the shaft 1, serving to keep the dog in contact with the wheel. Thus the shaft() is prevented from revolving, and the pinion n is allowed to revolve on the shaft as the pinion passes over the rack c on its return from the end of it. As the shaft 0 is held and prevented from turning, the rake will be held up and carried back toward the front of the machine as the shaftI swings round toward the block N. Just before it strikes this block the foot of the dog if strikes on a block, r, on thebar L, and the dog is lifted out. of the ratchet-wheel q, (see Fig. 4,) when the shaft 0 is free to revolve, and the weight of the rake causes it to descend into the position seen in Fig. 1, ready to sweep the grain 011' the table. v

The manner in which the vertical shaftHis revolved a quarter-turn, or thereahout, and the shaft I is swung round, will now be explained.-

Attached' to and rising vertically from the frame 0 is ashort adjustable standard, S, Fig. 5, the foot of which is formed with a slit, m, ,which embraces the frame 0. A flatquadrantshaped piece, T, is hung upon the main shaft D, the shaft turning freely in it. A screwpin, 1, with a nut, passes through a slot, 2, in the standard S, and secures the piece T in position. This slot and the sliding of the standards S in the lrame 0 allows the piece '1 to be adjusted as required. Near the outer edge of the piece T is secured to its face a curved spring, a and a little farther in from its edge is a block,b.

Secured to the shaft D is a ratchet-wheel, U, Fig. 5., and dotted in Fig. 1, which revolves with the shaft, bearingagainst a shoulder and against the block b. A screw, 0, passing through. the hub of the wheel U secures it to th'eshaftD. AdjoiningthewheelU,and hanging loosely on the shaft D, is a box-wheel, V, Fig. 1, and detached in Fig. 6, which runs in contact with the hub of the wheel U, and is retained in place by the sleeve (2, which is attached to the shaft by a screw. The wheel V, which is hollow or formed like abox, contains a coiled spring, 6, Fig. 1, and dottedin Fig. 6, the inner end of which is secured to the hub of the wheel, and the other end atf to a piece, W, (detached in Fig. 7,} which is secured to to the frame 0 by suitable screws. This piece extends laterally from the frame (3, and is forked at its outer end into two parts, Nos. 1 and 2, the former of which enters a circular slot, g, in the inner face of the box-wheel V, and has attached to it at f" one end of the spring 0. Thus as the wheel is revolved in the direction of the arrow the springis wound Pivoted at i to the part 2 of the fork of the piece W is a long bent lever, h, the longerarm of which extends up within reach of the driv ers foot. It is widened out at this endat k to accommodate the foot, and is steadied in a forked arm, I, attached to the upper part of theframe of the machine. A spring, m, throws out this end of the lever, and keeps the other end in contact with the periphery of the wheel V. The lower end of the lever h is furnished with a hook, n, which catches a stop, 0, secured to the edge of the wheel V, and retains the wheel against the resistance of its spring 6 after it has been wound up, as will be explained. Pivoted to the inner face of the wheel V at r is a pendent dog, 12, which vibrates freely in a plane parallel to the face of the Wheel. The lower end of this dog peis bent out at right angles, and rests upon and engages with the ratchet-wheel U, as seen in red,Fig. 5. A pin, 9, on the face of the wheel V prevents it from swinging out'too far.

. A beveled cogged segment, X, on the inner face of the wheel V engages with another beveled cogged segment on an arm, Y, secured to the vertical shaft H. Thus as the wheel V revolves the shaft His caused to turn in its bearings.

The manner in which the reach of the rake toward the front of the machine is adjusted will now be explained.

\Vhen it is desired to incline the box K at the end of the shaft I, so that the bar P, as it slides through the box,shall descend in a line inclined to the perpendicular, the shaft Iis turned a short distance in the sleeve B, and is secured by the pin passing through the sleeve into the shaft. As turning the shaft I raises or lowers the shaft 0 and parts connected therewith, it becomes necessary to alter the height of the shaft I above the plate L, that the roller i may be kept in contact with the curved way M. This is adjusted by means of the movable cap A on the top of the vertical shaft H.

Operation: The parts being in the position seen in Fig. 1, as the main or driving wheel E revolves in the direction of its arrow when the machine is being drawn along, a tooth of the ratchet-wheel V, which is fast to the main shaft D, catches the dog 1;, and carries it round between the wheel U and the curved'spring a on the stationary piece T, revolving the wheel V about a quarter-turn and winding up the spring 0, when the stop o is caught by the hook it on the end of the lever h, and the do p, being forced out from under the tooth of the wheel U by the block b, escapes from under the end of the curved spring a, and the ratchetwheel U revolves without turning the wheel V, which is loose on the shaft D. The adjustment of the piece T regulates the length of time that the dog p shall be kept in contact with the wheel U, and consequently the distance that the wheel V shall be revolved. As the wheel V is turned in the direction of its arrow it revolves (by the connection of the cogged segments) the shaft H, which swings ound the shaft I, attached to the head of it, the roller 1 running on the. way M. By this movement of to revolve a distance proportionate to the.

length of the rack c, and, through the cog-wheel h and rack i; the rake Q is lifted up vertically,

or nearly so, clear of the grain which it has just swept off the table.- The dog it, engaging the ratchet g on the end of the shaft 0, prevents it from turning in the opposite direction, and holds the rake suspended while the shaft I is being swung back toward the front of ,the machine, the cog-wheel 'n turning freely on the shaft 0 when passing in this direction over the rack c'. After the rake has swept the v grain off the table and itis lifted up ont of the grain, as explained, the wheel V being locked by the lever h, the machine proceeds until sufficient cut grain has. fallen on the table R to makeanother gavel or bnnchfor binding, when the driverpresses with his foot on the end K" of the lever It and sets free the wheel V, when by theinncoiling of the spring 0 the-wheel is turned in the direction opposite to that indicated by its arrow, and swings back the shaft I toward the block N on the end of the way M. The instant before this shaft strikes against the rubber cushion d on the block N the dog it is tripped by'the block wand the shaft 0 being set free, the weight of the rake- Q causes it, to descend, its rod 1 sliding in the box It until arrested by the pin m in the-rod, which pin supports the rake suspended with its teeth within a short distance ofthe table R. The brake c retards the latter part of the swing of the shaft I, and gradnatesthe force with which it strikes the block N. When the wheel V is beingturned back by its spring 0 the bent end of the dog 1) is carried upon the outside of the curved-spring or. out of the way ofthe teeth of the ratchet-wheel U, until the shaft 1 brings up against the block N, when the dog 11 again swings into contact with the wheel U and iscanght by one of its teeth, and the rake is again swept over the table.

Whenthe machine is intended to be operated in grain the straw of which is shorter than usual the reach of the rake is adjusted byturning the shaft I, as before explained,so that the bar 1? descends in a line inclined to the vertical and reaches the. rake ont'nearer to the front of the table R, the pin m in the bar P being adjusted to allow the rake-teeth to descend near enough to the table. If, on the contrary, the straw is longerthan'usnal,

posite direction. t

It will be seen that by the above arrangement of ,parts I place the movements of the rake entirely under the control of the driver, who can keep it suspendedat the back of the machine until aqu-antity of cut grain, has fallen on thetable sufficient to make a gavel of a rereqnired and uniform size, without reference to the thickness of the standing grain through simply pressing his foot on the treadle k the behind the machine, the rake leaving it without scattering on tangling the grain in the least; or, if it is preferred-to lay-'the'grain in a continuous ;or nearly continuous swath in hold down the-treadle is, when the. hook nat rake will be regular and rapid, effecting this end,and by the adjustment of the reach oft-he .rake the machine can bemadeto work equally well irn either long or short straw.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. Raising the rake in the planein which it is inclined, by'mean's of the'devices above described,-for the'purpose specified.

2. Operating the raking attachment back and forth over the platform by means of the mechanism substantially as herein set forth.

' 3. Inclining the rake from a vertical plane to correspond with the length. of the grain bescribed;
