COMBINED TEDDER AND HAY-RAKE.

SPECIFICATION forming part of Lettersulatent No. 430,566, dated June 17, 1890.

Application filed February 14, 1888; i Serial No. 263,971. (No model.)

To all whom t may concern:

Be it known that I, SAMUEL L. DENNEY, of

Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in a Combined Tedder and Hay-Rake; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' The invention relates to an improvement in a combined hay tedder and rake, the object being to improve the same in particulars hereinafter appearing; and to that end the invention consists in certain features of construction and combination hereinafter described, and pointed out in the claims.

Referring` to the drawings, Figure l is a top plan view of the machine, showing the teeth locked for raking. Fig. 2 is a transverse section of the machine. Fig. 3 is a plan view of a section of the machine, showing the hooks z removed from the teeth and one tappet j ust after it has left the tooth-section. Fig. 4 is a. detail view showing a tooth-holding plate in section and a tappet in engagement therewith. Fig. 5 is a view-of a modied form of tappet. Fig. 6 is a view in perspective showing the connected mechanism for simultaneously operating the tappet-shaft and the tooth-locking bar in opposite directions. Fig. 7 shows detached views in longitudinal and transverse section of the sectional spindlebox and the rotary spindle therein. Fig. S shows theconstruction of the pawl-and-ratchet connection of the operating-wheel. Fig. 9 is a sectional view of the parts shown in Fig. S, together with the spindle and spindle-box,

` the said parts being in co-operative position.

Fig. lO is an enlarged side elevation of the sectional spindle-box. Fig. 1l is a view of bracket d, showing the connected parts of the machine; and Fig. l2 is a detached view of lever S.

A represents the axle of the rake, preferably made of wood, and to its ends are secured by means of clips, bolts, or similar means, the spindle-boxes A2. These boxes are formed in half-sections, the adjacent edges of which are provided with beads or ribs of, adapted to interlock, so that the half-sections may be separated from each other to accommodate a large or small sized spindle without disarran gement of parts. The sections are provided on their sides with bosses a6, formed at intervals. These bosses are paired, one being formed on each section and adapted to receive bolts or clips to hold the sections together and to the axle, while there is ample space left between them to receive a packing al, t-he latter being in such shape that it may be gradually removed as the spindle-boxes or spindles become worn and loose. To insure a quick and exact iit of the half-sections of the spindle-boxes, a lug a8 projects laterally, preferably from the lower section, and a socket 'a9 is formed on the side of the upper section in `position to receive said lug as.

The spindle c is provided with a head e2 on its inner end, adapted to hold it in place, and the outer end of the spindle projects beyond the end of the box just a suflicient distance to nicely'receive the wheel of the rake,which latter is secured to the spindle by a pin e or other device being inserted through the hub and spindle. The shafts or thills B are secured to the'axle Ain the usual manner.

To the front of the axle A a sufficient number of `brackets D are secured, and each bracket is provided with a j ournal-box E, in which the tappet-shaft F is supported.

Upon the hub of the operating or right wheel, considered from the rear, the gearwheel a is loosely mounted. This wheel is provided with a hub am, and the inner wall of said hub is provided with ratchet-teeth a, A spring-actuated pawl h6, pivoted on the hub of the groundwheel A', enters the hub am of gear-wheel a, and by the action of its spring always rests in engagement with the ratchetteeth in a manner to rotate the gear-wheel a with the ground-wheel A when the latter moves forward, and to remain fixed when the ground-wheel moves in an opposite direction, or, in other words, when the rake is backed.

Upon the righthand end of the shaft F is afiixed the pinion G, which is adapted to mesh with the gear-wheel a. The shaft F is so adj usted in its boxes E as to permit an endwise movement, to thus remove the pinion-wheel Gr from its meshing counterpart CL on the hub of the ground-wheel. This movement is effected by means of the lever E', pivoted between the ears e5 of the bracket e on one of IOO lever Y is pivotally secured.

furnished with a laterally-projecting wrist? pin y, which receives the other end of link Y.

the shafts or thills, or in other position within the reach of the driver, and is limited bythe collar 6 secured thereon and the adjacent bracket D. The forked end g5 of this lever spans the tappet-shaft F, between a pair of collars g, and, if preferred, may be otherwise connected to the shaft. To lock the shaft F in either vposition any sort of device may be used.

To the axle A two depending brackets cl are secured, and each of said brackets is provided with a box e. These boxes c" are intended to hold in position the tooth-supporting shaft I. Upon the ends of the shaft I arms L are affixed. These arms L are of equal length, and have bosses g on their free ends, in whiclrthere is an angular' perforation for the reception of the locking-bar M.

The bar M is preferably made roundin the body and angular, as at h, at its ends to prevent it turning in the bosses g and yet permit afree endwise sliding movement.

In the rear end of the brackets (Z hingejoints i pivotally support the clearer-bar N. The clearer-bar N is provided with a number of tines or straight teeth N', that are given a proper position between the rake-teeth. One of these tines, preferably the central one, is provided with an upwardly-projecting arm X, to the upper end of which is pivoted a link Y. Projecting upwardly also from the axleAare a pair of ears x, and between them a hand- This lever is Now it is obvious that the inclination of the lines is regulated by thishand-lever Y when the lever is forward, the tines being about horizontal for raking, and when back they being inclined for tedding.

On the shaft I are loosely mounted the teeth-section plates K. These are shown in detail in Fig. 4. Any suitable number are placed on the shaft I a proper distance apart, a perforated boss 'a being formed integral with each tooth-plate to affordit support and permit a correct alignment of all the sectionplates K on the shaft I, they being free to vibrate on the shaft when operated upon to cause such motion. Each tooth-section plate has a rearwardly-extending plate o, formed integral with its other portions, this plate being formed flat on its top surface, and at regular intervals thereon grooved indentations 0' are made therein for the accommodation and secure holding in aligned position of the teeth O. These teeth O are made, preferably, of steel. rods, and each tooth is composed of a rod bent at one end to form a loop with parallel sides, the width between these parts being so proportioned to the grooved indentations in the plate o as to permit the proper retention of the teeth in these grooved indentations. Any proper number of these teeth may be located on a plate; but I have found it most convenient to provide three teeth, secured, as just stated, to each sectionplate. bearing-washer P, grooved in its under side to correspond with the groove in plate o and placed upon their top surfaces, a squarebodied bolt p passing through a squared hole in each washer, the bolt being threaded on its lower end to receive a securing-nut upon it. By grooving the plates o and the washers P spacing-flanges are formed between the parallel grooves on each plate. These fianges enter between the sides of the loop of each tooth and assist in holding them in proper position in relation to its supporting-plate K. The tooth-plates K are each provided with an arm R, that is formed integral with the bosses n. These extend forward beneath the axle A. The ends of these arms R are forked to form a support for an anti-friction roller u. These rollers u are provided for the impinging action of cam-tappets that are mounted on the shaft F, as will be explained. The bosses a are slotted at a point m through their bodies. These slots m are made for the reception of the studs or pins fm', that project a proper distance from the body of the shaft I to engage these slots, the slots being of a sufficient length to permit a proper swinging movement of the tooth-holding plates K upon their supporting-shaft I. curing these plates holds them from lateral displacement, while it permits vertical oscillation.

The construction of the tooth-section plates K, having their rearward-projecting plate 0 extend some distance to the rear of the shaft I, on which they oscillat'e, proved of great advantage in practice, as the weight of these section-plates, together with the attached teeth O, aid by their gravity the quick return of the teeth to the ground when the tedder is in use. The teeth O are made in the usual form to curve rearwardly and downwardly, except at the point, where they are straight for a short distance, and are of such a relative length in regard to location upon their shaft as to permit any engagement with the ground surface when depressed by design of the operator or through the action of the tedding-gear.

Rigidly secured on the shaft I is the bracket arm or lever S, formed substantially bell-crank shape and provided at its rear end with a fork or perforated end S2, which spans the locking-bar M, permitting the latter a free sliding motion therein, the end of the lever operating to hold the teeth down, and being limited in its movement in one direcon by the stop S9, projecting from the axle is loosely connected by a link S5 to thef'rear end of the rake-tooth-elevating handle or lever V, pivoted to the cross-bar V:2 on the shafts or thills. v

On the lshaft F at proper points are secured thetappets WV by their hubs t. These tappets IV are preferably made with two oppositely-projecting arms suitably curved to en- The teeth are secured in place by a This method of se- V IOO IIO

The upper end S3 of the bell-crank lever gage the anti-friction rollers u on the ends of the arms R of the tooth-plates K. The position assigned to the tappets IV must be such that when the gear-wheel on the end of Athe shaft F is in engagement with its driving gear-wheel on the hub of the ground-wheel A, the tappets will be directly opposite the anti-friction rollers on the arms of the tooth- `plates K, the relative location of their respective shafts F and I being such as to permit a sufficient impingement of the curved tappet-arms upon these rollers to lift t-he tooth-section plates a proper distance, and thus raise the teeth of the rake sufficiently to drop a load when necessary.

'Ihe tappet for each tooth-plate K is preferably set out of a direct line with the other tappets, so that their opposed tooth-sect ions K will be operated upon successively. This method of construction is available when the device is to be used as a tedder.

In order to facilitate securing or removing the tappets from the shaft F, I prefer to form the tappets in two similar sections, as shown in Fig. 5, which sections, when placed on the shaft, are bolted together, thus securely locking them in place upon the shaft.

Upon the locking or pressure bar M are placed the small hooks z. These hooks are so formed and located that they will project over and bear upon the teeth of each toothsection plate when the bar is shifted to the right to use the machine as a rake, one of these hooks being furnished for each tooth, the locking-bar M being intended to support the teeth O in place and hold them firm while in use as a rake. The extended ends h of the bar M will permit the bar to be shifted endwise when the rake is to be changed into a tedder, this endwise movement carrying the hook z away from the teeth O, and thus permitting them to rise and fall successively by the' action of the tappet-arms upon the anti-friction rollers u.

A long lever T2, peculiarly bent to suit the position in which it is placed, is pivoted at 7 to the lower side of the axle A, and its forward end is connected with the hand-lever E by passing loosely through an eye elo, formed therefor, or in other similar manner, so that it receives motion from said lever E. The rear end f5 of this lever is bifureated,and between its branches receives loosely a long curved pin or arm f, projecting downwardly and curving forward from the holding-.bar M, the object of this formation being to keep the lever Tzin engagement with and admit of the endwise movement of bar M thereby in whichever position the rake-teeth be, whether elevated or depressed. Thus it is clear from the very fact that the two ends of a lever move simultaneously in opposite directions lthat the connected shaft F and bar M must also move simultaneously in opposite directions.

A seat is fixed in a convenient position to the lever V, so that the hand and foot of the driver may be used with proper effect when' the vibration of this lever V is necessary to discharge a load from the teeth of the rake to form the raked hay into windrows.

In operating the machine as a tedder, the

shaft F is geared with the ground-wheel A so that the tappets IV will be in line with the teeth-plates K. Forward motion being given tothe tedder, the revolution of the shaft F will operate the tooth-sections K successively, and there will be, by the alternating successive rise and fall of the teeth-section plates K, a series of small loose flakes or elevated heaps of the hay arranged at spaced intervals over the field, the weight of the toothsection plates from their point of bearing on the shaft I causing a quick return to the grass of the teethpoints when released from the tappets W.

Then used as a tedder, the clearing-bar N, with its affixed tines, must be lowered to permit a closer adjustment of these tines with regard to the points of the curved teeth O, as the operation of tedding the hay to cure it does not require so great a lift of these teeth O to accomplish the' desired result. This change of position is accomplished by the lever Y.

To change the machine to rake hay the gear-wheels are disconnected by simply moving the lever E in the opposite direction, the teeth of the rake by such movement being all locked together by the holding-bar M,I and the shaft F being thrown aside in the same operation.

It is obvious that without any radical change of the parts of this machine a tongue or draft-pole may be substituted for a pair of thills or shafts, and I desire to have it understood that in some cases I may prefer to make this change to suit the land and crop to be operated upon.

It is evident that other slight changes in the construction and relative arrangement of the several parts might be made without departure from` the spirit or exceeding the scope of my invention; hence I do not wish to restrict myself to the exact forms of construction shown,but claim reasonable latitude to make such changes as will fall within the spirit and scope of this invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isj l. In a horse hay rake and tedder, the combination,- wit-h an axle and spindle-boxes secured thereto, of spindles adapted to rotate in said boxes, each spindle having a head on its inner end, ground-wheels mounted on the spindles, and pins for locking the wheels to the spindles, substantially as set forth.
