UNITED STATES PATENT CFEICE.

J. C. STODDARD, OF WORCESTER, MASSACHUSETTS.

,Specification forming part of Letters Patent No.Q4,588, dated June 28, 1859; Reissue No. 3,481, dated June 1, 1869.

To ail 'whom it may concern r Beit known that I, J. G. STODDARD, of the city and county of Worcester, in the State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Hay, of which the following is a full, clear, and exact description.

The object of the first part ot' my invention is to render the teeth of a hay-making machine rakes, and a catch toy lock the two frames together to hold up the rakes, when required.

The improvement further consists in com bining a draft-frame carrying the driver with avibrat'abl'c frame carrying rotating ralres, which frame can be raised or lowered at pleasure by the driver.

lThe improvement further consists in a novel method of combining, in a hay-making machine'1 two wheels, a frame arranged between the wheels and carry ing the driver, and a vibratable frame, also arranged between the wheels and carrying rotating rakes.

The object of the next part of my invention is to use a rake wider than the distance between the wheels; and the improvement herein claimed consists in a novel method of combining a trame vibratable or adjustable on the axle of the' supporting-wheels with rotaryV rakes mounted on the frame outside the periphery ofthe driving-wheel, and raking a swath wider than the distance between the wheels.

The im provement further consistsin a novel method ofcombining a frame vlb'ratable about the axle of the'supporting-wheels with rotary rakes driven from the outer side of the drivingwheels. The object of the next part of myinvention is to rotate the Takes continuously while allowing them to be vibrated or adjusted up or down;

to which end the improvement consists in a novel method of combining rotating fakes mounted on a frame vibratable about the axle of thesupporting-wheels and a main frame with a driving-belt traversing pulleys on the main axle and rake-shaft.

The improvement further consists'in a novel method of combining a perforated rotating shield with teeth adjustable radially4 relatively to the axis of rotation, and so arrangedas to be protruded more or less through the shield.

The improvement further consists in a novel method of combining with a hay-making machine rotating ra lie-teeth, movable radially relatively to their axis of rotation.

The object ofthe next part of my invention is to convert the machine from a hay-making to a hay-raking machine.; to which end the im,- provement consists in a novel method ot combining with yrotating teeth a stop to hold the teeth and cause one set of them to act as a rake.

l The improvement further consists in a novel method of making one setotl radially-adjustable teeth longer than the others,in order that the rake-head may be more elevated when ra king than when making hay.

The improvement further consists in a novel method of combining rake-teeth movable radially relatively to their axis with a frame vihratable about the main axle.

In the accompanying drawings, which show all my improvements as embodied in enemachine, Figure l represents a view in perspective ofthe machine as arranged formalring hay; Fig. 2, a plan or top view ofthe same; Fig. 3,a vertical longitudinal section through the machine, showing an interior view ot' the rakes arranged for making hay; Fig.. 4, a vertical transverse section through the ralxes when arranged for operation asa horse hay-rake; Fig. 5, a view in perspective of one of the rakes detached.

In the drawings two wheels, A A, are shown as revolving on an axle, B. A frame, C, is mounted on this axlc'between the wheels. An extension of this trame forms the thills D. A seat, E, for the driver Ais mounted on springs fixed tothe frame. Two-arms or levers', E, having their fulcra upon the axle B, outside 'slots ggin the cylinder l. -iixed in their positions by pins, which pass the frame C, extend infront ot' the axle above the frame, and are connectedby a crossbar so as readily to be operated by the foot ot the driver. These levers likewise extend in rear of the axle, beyond the periphery ofthe wheels, and serve as bearings for the rake-arm G, and

constituting what I termV a vibratable or l, holds the levers F, and consequently theY rake-teeth, above the ground when it is nec es'saryto stop theworking ofthe rakes. When the arms F are released by the latch the rakes descend by their own weight and the raking commences.

An arrangement may be attached to the front ot' the platform, and placed under thel control of the driver, for holding the rakingdrnm in a fixed position during the operation ot' raking or makinghay; but this will be optional in the construction and use ot' the machine, and not necessary to describe.

rlhe drum for carrying the rakes is composed of a shaft or axle, J, and two cylinder-heads, K K,tixed to the axle near its ends.. The axle projects from either side of the heads K and rests in bearings on levers F. Betweenthese hearings and the drum-heads K on the axle J are two pulley-wheels, L, keyed to the axle, and over which pass bands N, .which are carried over large driving-pulleys on the sides of the wheels A. These bands are kept tight around the pulleys by adjustable tension-pulleys c, fixed to the levers F, and under which pulleys the bands pass. Only one ot' these hands may be necessary for rotating the drum, and only one is shown in the drawings. The drum-heads K are surrounded by a sheet-metal cylinder, G, and the rakes are inclosed within this cylinder.

The rakes or the rake-heads d have square portions ci'ormed on either end, as clearly shown by Fig. 5 ot' the drawings, and these squared portions tit into slots ff on theinside ot either drum-head K, which slots are en- -larged near the axle J, so as to allow the l The rake 'heads are all placed within these slots between square portions e e to turn therein.

the two drum-heads, so that their tines or teeth, when protruded, will project through They are then through the heads and into their ends, and in x these positions the machine is used for haymaking. The advantage of this arrangement is as follows: The cylinder serves as a perfect Sguard to prevent the hay from entangling itself in the tines of the rake, and thereby stop the rotation ot" the rakes, as is frequently the `case with the machines in use.

At the same longer than those ot' the others, as represented by Figs. 2, 3, and 4, R being the rake, having the long teeth, which is iixed in the positionl shown by Fig. 3 when used for making hay,-

and in the position indicated by Fig. 4. when adapted to raking only, the other rake-teeth being closed up around the axle and held in this position by any suitable device. The motion of the cylinder is here regulated by apin, h, projecting from the pulley L, which strikes the hooked piece 7c. on the shoe H and prevents the cylinderfroni turning. `The arms F F are used to raise and lower the cylinder to relieve the rake ot' its load. v

What I claim as my invention, and desire to secure by Letters Patent, is-
