IMPROVEMENT IN HORSE-RAKES.

Specification forming part of Letters Patent No. 36,426, dated September 9, 1862 YReissue No. L83?, dated December 6, 1864.

To all whom it may concern.-

Be it known that I JOSEPH H. SHmEMAN,

.of East Berlin, in the county of Adams and State of Pennsylvania, have-invented a new and useful Improvement iu Horse Hay-Rakes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and letters of reference marked thereon, like lettersin the several figures indicating the same or analogous parts, and in which drawings- Figure l is a longitudinal section, showing the attachment of the hand-lever to'the axle of the rake; and Fig.2isa front sectional view of said lever, together with the main operating parts of the machine.

In the drawings, A indicates a wheel which revolves loosely upon the axle B, and A a wheel firmly attached to said axle and revolving with it. Collars, as at c c, are connected to the under side ot' beams d d, which constitute the sides of the main frame of the machine, said beams being connected with transverse beams e e in front and in'rear of the axle, as shown, thus forming a support for the drivers Seat f, thills g g, perforated toothboard B', rake-teeth t', elbow-lever j, andinclined way77 k. The main frame and parts supported thereon are thus sustained by and articulate upon the axle by the collars c c. Planks l l are secured to the cross-beams e e', as shown, the latter one, l', serving as an immediate support tothe drivers seat f,and also to the inclined way k.

The drivers seat, it will be seen, is situated at one side of a point central of the length of the axle B, and near the wheel A', which is permanently attached to the axle, so that the weight of the driver, when occupying the seat, will mainly be thrown upon said wheel. By this means the firmness of the tread of the wheel A' is increased, and any liability of its slipping upon the ground when the rake-teeth are charged with a heavy draft of hay is avoided.

Onthe axle B, beneath-the drivers seat, a cog-wheel, L, is permanently attached, so as to revolve with the wheel A' and the axle. Cogs m, as shown, project from the workingface of said cog-wheel, and as the wheel A' revolves engage with the lip n of the handlever N, thus compelling said lever to articulate on said axle and move forward in the direction of the rotation ofv said wheel, as will be described. Nearly central of the length of the axle a loose collar, P, is made to embrace theaxle, as shown, and articulates freely there on. To this collar, as at r, the lower end of the hand-lever N is pivoted, so that it may be made to approach the cog-wheel L by the hand of the driver, or be drawn away therefrom by the action ot' springs s and s', applied as shown, the main spring, s, at its upper end being connected to the hand-lever by the link s2.

As represented, a perforated bar, T, connects the hand-lever with the upper limb of the elbow-lever j, which has its axis of motion on the bar or rod V, upon which the rake-teeth t'articulale. The etfective length of the bar T may at will be increased or diminished by inserting the hook j' of the elbow-lever j into either oneof the perforations through said bar, as may be desired. bow-lever is made toproject through an aperture, ain the perforated or slotted tooth-board B', through the slots of which, as at a', the rake-teeth pass, and wit hin the range ot' which slots or apertures a' said teeth are permitted to rise and fall to accommodate themselves to inequalities ofthe ground without effecting an elevation of the tooth-board B', through which they pass.

Rod V at its ends is supported by uprights o c, as indicated, said uprights being driven into or otherwise properly secured tothe framing d d, as shown. This rod, as represented in the figures, passes through a series ot' rollers, b', to which the inner ends of the raketeeth are secured. Each one of said rollers' plays loosely upon the rod V and independent of motion of the tooth-board B is coincident or in line with the axis of motion of the teeth i, so that when the teeth are elevated by the rising ot' the tooth-board said teeth and board The lower limb of the el- Ychine.

' teeth t' are elevated from the position shown in the drawings they will rise simultaneously and coincident with the board B', through which they pass, and that as the said board and teeth have the same axis of motion they teeth, during such actof elevation, will simply rest upon the board B', instead of being thrust longitudinally through the slots a', thereby causing an increased draft of the ma- This state of rest of the teeth i upon the board B' is the same whether the latter is in the act of elevation or depression.

A catch, k', is pivoted to the hand-lever N, so that when the hand-lever is made to approach the inclined way kit will engage with lthe latter and hold the hand-lever in the position shown in Fig. 2.

We will suppose that thevmachine has gathereda'desirable quantityof hay to form a windrow, and that the hand-leveris still occupying its normal \ertical.position, and with its lip n out ot' contact with the cogs ofthe wheel ll, and that the driver or operator is desirous of discharging the hay. To effect such discharge the driver will grasp the leverN with his right hand, and by drawing it toward him a proper distance the lip n of the lever will be brought within the path of revolution ofthe cogs m of the wheel L, and the catch k', striking the inclined way k, will engage with it, as shown in Fig. 2. 1n this position of the hand-'lever the continued rotation ofthe wheel A will turn the hand-lever on the axle B with a downward and forward movement until the catch k' has traversed the face of theway k, and has also passed beyond the forward portion ofsaid way, at which moment the tension of the springs s and s will cause the lever to resume its original vertical position, thus freeing it from contact with the cog-wheel L. y

Itis evident that during such movement of the hand-lever the rake-teeth 'i will be elevated upon and with the tooth-board B' through the instrumentality of the elbow-leverj and connecting-bar T, and that the time at which the rake-teeth will be permitted to fall back into the position shown in the drawings will depend upon the working length of the bar T, according as it is hooked to the elboW-leverj in one or the other of its holes e'. apparent that the driver, with a backward draw upon the hand-lever N, can, through the instrumentality ot' the connecting-bar T, elbowleverj, and tooth-board B',force the rake-teeth i down to their work-an operation highly neo- It is alsoV essary, since, after the teeth shall have gathered a quantity of hay less than enough to warrant its discharge, the tendency of the teeth is to rise from the ground and not perform thorough work.

My improvements relate specially to that class of rakes in which the axle and one of the supporting-wheels thereon are employed as the means for discharging the gathered hay from the raketeeth-that is to say, the power of the horses is transmitted through these devices to the raketeeth, and made available for lifting the weight of the' rake and its load during the act of freeing the teeth ofthe hay which has been collected by them. This being the character ot' my improvements, the utility ofthe pendent hangers, the tight wheel, and the drivers seat, all as described, will be evident.I

Having thus described my invention, what I claimv as new, and desire to'secure by Letters Patent ofthe United States, is

l. Suspending the hand-lever N upon the axle B, so that the former may articulate upon the latter, in the manner and for the purpose described. v

2. The inclined way lc, in combination with the hand-lever N, arranged and operating substantially in the manner and for the purpose set forth. y

The perforated bar T,in combination with the hand-lever N, arranged and operating substantially in the manner and for the purpose set forth.

4. The arrangement ot' the drivers seat to one side of the center of the length of the continuously-rotating axle B, and in relation to the tight driving-wheel A', lever N, inclined way k, and perforated bar T, in the manner and for the purpose set forth.

5. The arrangement of the hangers T' of the tooth-board B' on the same rod or shaft that the rake-teeth are supported and articulate upon, in combination with an axle which transmits the power of the team to the rake during the act ot' discharging the hay from the teeth, substantially as and for the purpose set forth.

b'. The hangers T of the tooth-board B', constructed and applied in connection with a rake which operates to discharge its load by the power of the team through the agency of' the axle, substantially as set forth.

Witness my hand in matter of my application for reissue of patent for improved horserake.
