" GEORGE N. PALMER, OF: GREENE, N. Y., ASSIGNOR TO CHARLES LA DOW.

HORSE-RAKE AND HAY-SPREADER.

SPECIFICATION forming part of Reissued Letters Patent No. 9,050, dated January 20, 1880.

7 Original No. 65,113, dated May 28, 1867. Application for Reissue filed December 9, 1879.

To all whom it may concern Be it known that I, GEORGE N. PALMER, of Greene, in the county of Ghenango and State of New York, have invented certain new "and useful Improvements in Combined Horse- Rake and Hay-Tedding Machine, of which improvements the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this-specification, and in which Figure 1 represents a plan or top view of a machine embodying all theimprovem ents herein claimed; Fig. 2, a vertical longitudinal section therethrough on the line 1 1 of Fig. 1.

The invention set forth. in this specification relates to additional improvements on a combined horse-rake and hay-tedding machine for which Letters Patent No. 51,473 were granted to me December 12, 1865.

The first part of my invention relates to mechanism for raising and lowering the teeth. Its objects are to hold the rake-teeth down to their work with a yieldingpressure, and to compensate shocks caused by the vibrations of the rake-frame, which ends I attain by combining a main frame, a rake-frame capable of rocking on pivots thereon, and springs, which always tend to depress the rake-teeth.

The object of the next part of my invention is to increase the efliciency of the operation of the apparatus by diminishing the power required to rock the rake-frame on its pivots, which end I attain by balancing the rake-frame, which rocks on pivots on the main frame, and interposing springs between the main and rake frames to depress the raketeeth.

The object of the next part of my invention is to enable the operator from his seat on the machine to adjust the depressing mechanism of the rake-teeth, which end I attain by interposing counterbalancing-springs between the main frame and a rake-frame rocking on pivots thereon, and regulating the tension of said springs by suitable adjusting mechanism.

My improvement further consists in combining .a main frame, a balanced rake-frame rocking'on pivots thereon, springs to depress the rake-teeth, and a lever to rock said frame to lift the teeth when desired.

, The object of the next part of my invention is to utilize the power of both wheels automatically to lift the rake-frame to. clear the teeth of matter gathered thereon and quickly to release them to leave them free to resume their normal working position, which ends I attain by combining driving, carrying, or supporting wheels mounted loosely on an axle, backing-ratchets connecting each wheel with its axle, a mainframe carried by the axle, a balanced rake-frame rocking on pivots on the main frame, springs interposed between the main and rake frames, which always tend to depress the rake-teeth, and a lifting-cam on the main axle.

The object of the next part of my invention is to raise or lower the rake-teeth rap idly and effectually, which end I attain bycombining a main or supporting frame, a rake frame pivoted thereon, short levers, also pivoted on the main frame, and spring-teeth carried by the short levers and resting on the rake-frame, so that as the rake-frame rocks on its pivots the rake-supporting levers, being of shorter radius, rise more quickly.

My invention further consists in combining a main frame, a rake-frame, their pivot-connections,- shortlevers pivoted to the main frame, spring-teeth carried by a rake-headmounted on the short levers and resting on the rakeframe, and clearer-teeth mounted on, the main frame.

The next part of my invention relates to that class of implements having spring-teeth mounted in gangs, sets, or ranks transversely to the path of the machine and in different vertical planes. Its object is more thoroughly to operate upon the substance traversed, and to'allow the teeth of one gang to yield backwardly without interfering with those of the rear gang, which ends I attain by mounting on a supporting-frame gangs, sets, or ranks of spring-teeth, extending transversely across the path of the machine, and with the teeth of one set working in the spaces between those of the other.

My invention further consists in combining a main frame, a rake-frame rocking on pivots thereon, a rake-head and its. spring-teeth mounted on said rake-frame, short levers pivoted on the main frame, and a second rakehead and its sprin g-teeth mounted on the short levers and resting on the supplementary frame. The next part of my invention relates to the method of connecting the driving-wheels and driving-axle. Its object is to enable the driver readily to throw either or both of the drivingwheels into or out of gear, and yet to protect the baeking-ratchets from clogging or injury, which ends I attain by inclosing the backingratchets in'a casing, which also protects the disengaging mechanism.

The object of the next part of my invention is to provide an adjustable stop to regulate the vibrations of a rake-frame vibrated by the revolution of the carryingwheels, to which end my invention consists in combining main carrying or supporting wheels, a main frame, a rake frame, mechanism for vibrating the rake-frame by the revolution of the wheels, pivot-connec-t-ions between the frames, and an adjustable stop interposed between the frames.

To. enable those skilled in the art to construct or use my improvements, Iwill now describe the construction andoperation of a machine embodying them, with reference to thedrawings.

The drawings show two main carrying, driving, or supporting wheels, A A, revolving loosely on an axle, B, carrying ratchet-wheels b on each side thereof. A dog or pawl, a, pivoted on each wheel-hub, engages, when desired, with the teeth of its ratchet, in contact with which it is normally held by a spring, (4. These backiugratchets, it will be observed, are arranged on the inner side of the drivingwheels, and they are inclosed in a casing, a through which thumb-screws I) operate on the lever ends of the pawls, as seen in Fig. 1, to throw the pawls into and out of gear with the ratchets.

The pawls, it will be observed, are shown as curved to conform to the shape of the easing, and are pivoted intermediate of their lengths.

By this mode of construction the backing- 'ratchets are held in gear to rotate the axle when moving forward, while the ratchets may readily be thrown out of gear, so as to permit the wheels to revolve loosely on their axle.

By incasing the ratchets extraneous matter is prevented from being caught and wound up by them.

A main driving axle or shaft, B, revolves in suitable hearings in a main frame, 0, shown as consisting of thills or shafts G 0 extending behind the axle, arranged at suitable distances apart, pa allel to each other and to the carrying-wheels, and connected by suitable cross bars or braces, the front cross-bar, D, being arranged in front of the axle.

The seat E for the driver is shown as located over the main axle and mounted on suitablesupports 0, secured upon the main frame.

A secondary supplementary rocking Takeframe is shown as composed of longitudinal bars or beams F F, connected and braced in front by a cross-beam, F beneath the drivers seat. This frame, it will be observed, extends both in front and rear of the main axle, being connected with the main frame by pivots f, which permit it to rock freely vertically.

A rake-head, G, resting on the beams F F of the rocking frame, is mounted on two short levers G Gr, connected with the rear ends of the thills by pivots c, which permit the short levers to swing vertically, so that by the action of the rocking rake-frame as it rises the spring rake-teeth gare thrown upward and backward, being cleared from the hay as they rise by the aid of the clearing-fingers a, mounted on the cross-bar N, secured above the main frame by standards a.

An adjustable rake head or shaft, H, carrying spring-teeth h, is mounted on the rocking frame F F in rear of the lifting rake-head just described, in the manner shown in my patent above mentioned.

It will be observed that by the organization shown the weight of the rocking frame preponderates to the rear of the pivots on which it rocks, and the teeth tend normally constantly to bear upon the ground. This tendency is overcome, however, by weighting the crossbar F so as to balance the rake-frame on its pivots.

To counterbalance and regulate the movements of the balanced rocking frai'ne, springs O, secured upon the main frame, press upwardly upon screw-hooks 0, projecting laterally from the rocking frame, the pressure ofthe springs beingregulated by adj usting the screwhooks. The adjustment of these hooks also serves to give more or less vertical movement to the rocking rake frame. Where the crop is light but little motion is required. here it is heavy a greater range of motion is necessary.

The springs may be secured to the shaft-timbers C O or Whiffletree-bar D, their resilience being sufficient to keep the front of the rocking frame elevated, so as to hold the rake in workin g position, and to bring said rocking frame in range with the liftingcam on the main axle, or within reach of the rocking-lever L, pivoted on the frame within easy reach of the driver when in his seat; or the rocking of this balanced rake-frame may be accomplished by the driver pressing with his foot on the main crossbar or foot-piece F The raketeeth are thus normally constantly held upon the ground with a yielding pressure, and when lifted are promptly returned to their work. By this construction shocks caused by the vibrations of the rake-frame are compensated and elasticity imparted to the working of the machine.

The operation of the machine will readily be understood from the foregoing description.

Having thus described my improvements, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbefore set forth, of a main frame, a rake-frame, their pivot-connections, rake-teeth mounted on IIO the rake-frame, and spring meehanisminterposed between said frames, which tends eonstantly to depress the rake-teeth.
