-Our invention has relation to certain new larged, on the line c c f Fig. 1, showing morel and useful improvements on that class of ma lchines which are convertible either into a rake or tedder at the will of the driver, and it has particular reference to that character of machines` covered by Letters Patent granted on the 13th day of December, 1887, and numbered 374, 795, as will be more fully hereinafter set forth.

The invention consists in certain novelfea- 6o tures of construction and combinations of parts, that will be fully understood from the following' description and appended claims, when taken in connection with theannexed drawings.

. In order to enable others to fully understand Aand construct our invention, we will now proceed to describe its construction.

Referring to the annexed drawings by letter, A designates the axle, on which are loosely `journaled the ground or drive wheels B. Upon the inner' end of the hub of-one of the groundwheels is secured a diskor plate, C, which has a radial extension, D, formed on it, this extension being provided with a perforated ear, E. Pivoted to the face of the plate C, so as to engage the teeth of the ratchet-wheel F, secured upon the axle, is a pawl, G, which has an outward] y-extendin g arm, H, provided with a curved pin, I, which passes freely through the perforated ear E on the extension of the disk. Between the ear E and the arm of the pawl, and surrounding the curved pin I, is a spiral spring, which serves to keep the pawl in constant engagement with the ratchet-wheel on the axle when the machine is in operation and moving forward, as shown clearly in Fig. 11 of the drawings.

Pivoted to the outer end of the extension D is a hook, J, which is designed to hold the pawl out of engagement with the ratchet wheel when it is desired to render the machine inoperative, as shown in dotted'lines in Fig. 11, where it will be seen the hook engages the end of the arm of the pawl. It will be ob- 95 served that by this arrangement of the pawland-ratchet devices the machine may be backed without communicating motion to thefaxle, and also that it may be rendered inoperative when it istransported from place to place,for roo for any other purpose.

Supported upon the axle of the machine, so as to be capable of a slight rcciprocatory move'- ment thereon,is the frame K,which is composed of thelongitudinal beams a a, to which the thills are attached, and the rearwardly-extending end beams, L L. These end beams, L L, are preferably metal castings and are provided with holes near their rear ends for the free passage of the axle ofthe machine. The extreme rear ends of these end beams of the frame support the usual clearer-shaft, M, this clearer-shaft being adj ustably held by means of the setscrews b, tapped into the ends of the beams L L. AParallel with the axle, and slightly above and a short distance in front of it, is the rake-shaft N, which is loosely journaled also in the metallic end beams, L, of the frame. Secured upon this shaft N are the independent rake heads or sections O, which have a partial rotary movement thereon, as fully shown and explained in our patent mentioned above. The rake-sections are each preferably provided with three curved rearwardlyextending rake-teeth. The rake-heads, as

shown in Fig. 6, are each constructed'of the main or lower plate, P, consisting of the portion Q, which is longitudinally grooved for the reception of the rake-shaft and provided with the forwardly-extending projection R, located about midway its length, and the three rearwardly-extending arms S, all preferably cast integral. Each one of these arms S is provided on its face with a longitudinal groove, T, for the reception and retention of a raketooth, the groove terminating in a circular depression, U, for the reception of the bent end of the rake-tooth. In the face of each of these arms, intersecting the groove, is also formed a recess, V, for the reception of an elastic collar or block, W, secured on the raketeeth near'their bent ends. When the raketeeth are placed in position on their arms, as shown in Fig. 6, the hooked or bent end of each tooth resting in the depression U and the elastic collar resting snugly in its recess, the cap sections or plates X, which are preferably correspondingly grooved and recessed, are bolted to the arms, the front ends of the cap-plates `being curved to embrace the rakeshaft, and the clamping bolts c passing through the perforations c in the center of the depressions U- and perforations c" in the cappieces. The grooves in these arms are somewhat larger indiameter than the rake-teeth, for the purpose of allowing them a slight play or movement therein. The center cap-plate has a. forward extension, X, (see Fig. 7,) corresponding with the extension R upon the portion Q, and through these two projections is passed a clamping-bolt, X. It will thus be seen that at the same time the rake-teeth are secured to the heads 'the heads are attached to the rake-shaft.

To prevent the rake-heads moving endwise on the shaft N, and at the same time allow them a limited rotary movement thereon, the shaft is provided with pins d, which work in internal segmental grooves d in the cap-plates X of the rake-heads. `It will be perceived by reference to Fig. 7 that while the rake-teeth are in a lowered position the pins d on the rake-shaft rest at the forward end of the segmental groove d in the rake-head, so that when the rakeshaft is rocked by'means of the lever M the pins will cause the rake-heads to move with the shaft, and thereby raise the raketeeth from the ground. This feature of our invention is fully set forth and claimed in our former patent, No. 374,795, and is therefore not claimed in this case.

The principal object in bending 'the ends of the rake-tceth into the shape of a hook and passing the securing-bolts through the centers ot' the depressions in which these hooks rest is to prevent the teeth from being withdrawn or pulled out of the heads, as is evident, and the object in slightly enlarging the grooves in which the teeth rest and passing the teeth through elastic collars or bearing-blocks set in the recesses in the arms S of the head is to give the teeth a yielding elastic movement in all directions, as is also evident. Thepeculiar importance of this feature of our invention will be fully appreciated when it is known that when the teeth areclamped in the ordinary manner rigidly and firmly between two metallic plates they quite frequently break off close up to the clamping-plates'when subjected to a sudden or unusual strain or shock. By my `method of securing the teeth this diticulty will be entirely obviated, as the elastic collar or cushion will relieve the teeth when they are subjected to a sudden or heavy strain.

Preferably upon the center arm of each rakehead is journaled an anti-friction roller, Y, which is somewhat larger than those usually employed in this class of machines, and is located near the rear end of the arm on which it is journaled. The rollers Y are journaled upon a pin e, projecting horizontally from the right side of the rear end of the arm, on which is formed a lug or enlargement, e', preferably being cast integral with the arm to afford a support for thejournal pin of the roller. Secured adjustably upon the axleby means of setscrews f, one to each rake-head, and in close proximity to the anti-friction rollers on the same, are the tappets Z, each of which consists, preferably, of the two oppositelycurved cam-shaped arms A', (shown in Fig. 5,) without rollers or other obstructions to become entangled with the hay. The advantages derived from this arrangement of tappets and rollers are, first, the weight of the rollers, placed, as they are, to the rear of the rakeshaft and of the rear projecting rake-head sections, is utilized to keep the teeth down -close to their work, which isespecially desirable where the ground is rough, as in that case the teeth have a tendency to springv up or vibrate too freely; secondly, just one-half the number of rollers are used than when they are placed on the ends of the tappet-arms, which is quite an item in the manufacture of a nump-A ber of machines; and, finally, the rollers are IPO IIO

not so liable to becomeentangled with the hay as when they are placed on the tappetarms.

In order to convert the machine from a rake to a tedder, the frame is shifted upon'the axle, this shifting of the frame bringing the rollers upon the rake-heads ina position to be-operated upon by the tappets, as fullypset forth in our former patent, mentioned hereinbefore. This shifting of theframe is accomplished by means of a horizontal lever, B', which is pivoted on a bracket, C', secured to the under side of the frame. The rear end of this lever is inserted in a grooved collar, D', secured upon the axle, and its forward end is engaged by the bifurcated lower end of an upright hand-lever, E', also pivoted to the frame of the machine within reach of the driver. By means of these levers the frame rnaybe readily moved back and ,forth upon the axle by the driver without moving from his seat. Pivoted to the handlever E' is a gravitating hook or catch, F', which engages with apertures f' in a plate on the frame, whereby the machine may be locked or held securely, whether it be working as a rake or a tedder. This pivoted hook has a lateral extension, G', by lmeans of which the driver may readily disengage the hook from the perforated plate with the toe of his hoot while he operates the lever by hand.

Running parallel with and below the rakeshaft, and jonrnaled in the frame of the machine a short distance in front of the same, is a vrock-shaft. H', to which a rocking movement is imparted by means of a foot-lever, I', which is pivoted to the frame near the drivers seat, so that the driver may conveniently operate it. This foot-lever at its lower end is connected to an arm, H", on the rock-shaft by means of the link J', and this link is made adinstable by means of perforations in the lower end of the foot-lever and in the arm on the rock-shaft. Projecting rearwardly from this rock-shaft are a series of curved arms, K', whichare so disposed upon the shaft that when it is partially revolved they impinge or press upwardly upon the lower sides of the forward projections R of the rake-heads, as shown in Figs. 2 and 5 of the drawings. By means of this arrangement ot' devices the driverl may instantly apply any degree of pressure to the rake-heads by simply operating the foot-lever by his foot without leaving his seat. This method of applying any desired degree of pressure to the rake-teeth is superior to the usual method of locking all the teeth securely together, for the reason that at times, when raking, the driver finds that it is necessary to press the teeth forcibly down to their work, which cannot be done by the usual manner of locking the teeth, while at other times it may be necessary to exert only a slight pressure upon the teeth; or in some cases, particularly where the ground is very rough and the teethsections should accommodate themselves to the unevenness thereof, he may find it necessary tov remove the pressure entirely.

Bolted to` the frame, in close proximity to the drivers seat, is a standard, L', to which is pivoted the hand-lever M', used for dumping while raking. This lever is connected at its vlower end by means of suitable links, N', to

from, passing, preferably,between the handlever and the standard, is a bar or plate, P', which is provided with a longitudinal slot, th rough which apin, Q', on thestandard passes. The rear end of this slot is turned downwardly and slightly forward, forming a short hookshaped slot, B'. The forward end of this slotted plate is provided with a foot-plates'. The object of this slotted bar P' is to hold the teeth in an elevated position whenever it is desired, this being accomplished by first elevating the teeth by means ofthe dumping-lever, then with the toe of the foot lifting the bar, so that the pin Q on the standard will enter the short slot B', as shown in dotted Vlines in Fig. 14, when the lever may be-released, and the teeth will remain in an elevated position.

In addit-ion to the abovedescribed method of dumping the machine by means of the hand- Vlever M', we have provided another, whereby the motion of the axle of the machine is utilized for that purpose, the dumping devices hei OOl ing thrown into engagement by a slight press'- f IOS directly behind the hand-lever M', is a plate or disk, T', which is provided with an npwardly-extending arm, U', and is held in its place on the ax/le between a collar, V', on the axle and aratchet-wheel, W'. Connecting the upper end of the arm U' with the arm O' on the rakeshaft are links X', which cause the two arms to move simultaneously. Pivoted to the arm U', so as to engage with the ratchet.- wheel secured on the axle, is a pawl, Y,which has a curved arm or extension, Z', which extends downwardly in front of the axle and is provided with a laterally-projecting pin, A", at its lower end. this arm of the pawl and secured on the rakeshaft, preferably formed integral with the arm O', is a depending arm, B". Secured to the under side ofthe frame and projecting rearwardly therefrom is a bar, C", which is pro`l vided atits rear endwitha hookor-bent portion, D", which engages with the pin A," on the arm Immediately in line withy of the pawl. This bar C"is kept normally backthese slots, of alimited backward and forward movement. Pivoted to the frame and engaging with an aperture' in the sliding bar C" is the footlever F, which is located in close relation to the drivers seat for convenience, and by means of which a forward movement may be imparted to the sliding bar C. When it is desired to dump the machine, all that is necessary to do is to press with the foot lightly upon the foot-lever F, which will impart a forward movement to sliding bar G, the rear bent end of the sliding bar engaging With the pin A and throwing the pawl Y into engagement with the ratchet-wheel upon therevolving axle, after which thc foot-lever may be released and the sliding bar will be carried backward by its spring to its normal position. As the axle revolves, the loose disk with its arm will be carried around a short distance with it by reason of the pawl and ratchet, and by means of the connecting-links between the disk arm U and the arm O on the rake-shaft a partial rotary movement is imparted to the latter, thereby elevating the rake-teeth from the ground and dumping or releasing the' hay therefrom. Wlien the teeth have been ele vated sufficiently to release all the raked hay, the depending arm B on the rake-shaft, by reason of the rocking movement imparted to this shaft, will contact with the depending arm Z of the pawl Y and disengage the same from the ratchet-wheel upon the shaft, when the rake-teeth Will be released and fall to the ground, their own weight being sufficient to carry them down the instant they are released, and all the parts will assume their normal po sition, ready for another operation.

AThe principal advantage in so constructing the dumping mechanism that the motion of the machine will serve to elevate the raketeeth whenever desired is that a small boy or very weak person may serve as a driver, all that is required of him being simply to press with his foot lightly upon the foot-lever,while the usual method of dumping by a hand-lever requires a man of some strength for the purpose.

1t is evident that we may do away entirely with the hand-lever for dumping the rake and use exclusively the foot mechanism.

The letter l designates a bracket projecting from the rear side of the frame of the ma chine to serve as an additional support or brace for the rake-shaft.

It will be observed that by our construction of the rake-heads practically all the metal used in constructing them, including the rollers thereon, is disposed to the rear of the rake-shaft, whereby it is utilized to keep the teeth down closely to the ground and thereby perform the raking operation in a more thorough manner. It will also be observed that by reason of the rake-sections being independ-v ently attached to the rake-shaft they may readily accommodate themselves to the uneven character of the ground without affecting the operation of each otherin the least,which can--` not be the case in most of the machines now in use, where a'weightbar or locking-bar is used to weight down or lock the teeth together.
