IMPROVEMENT IN .HORSE HAY-RAKES.

Specication forming part of Letters Patent No. 14,067, dated January 8, 1856; Reissue No. [,893, dated February 28, 1865.

DIVISION No. 1.

To all 'whom it may concern:

Be it known that I, RANDAL PRATT, of the township ol Marple, Delaware county, State of Pennsylvania, have invented a new and useful Improvement in Horse Hay-Rakes; and I do hereby declare that the following is a full, clear, and exact description of the same, as designated by Division N o. 1, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lis a plan view of my improved rake complete. Fig. 2 is a vertical longitudinal section of the same 'In the line :c :c of Fig. 1.

The same letters of reference in the diderent figures indicate corresponding parts.

The nature of the invention covered by this patent consists, first, in the arrangement of a standard-board, two sets of treadle-levers, two foot-boards, and a lifting-bar and a pressurebar, as will be hereinafter described; second, in the arrangement of a hand-rail, in combination with the stand-board, treadle-levers, footboards, and lifting and pressure bars, as will be hereinafter described; third, in the arrangement of the pressure-bar upon levers which are independent of the treadle-levers in their elevating motion, but are dependent upon said levers in their depressing motion, as will be hereinafter described; fourth, in a novel arrangement, in a wheeled rake, of articulating rake-teeth, alifting-bar, a pressure-bar, and treadles, as will be hereinafter described; fifth, in the arrangement, with raketeeth which terminate on their axial rod, or do not extend forward to be operated by a depressing-frame arranged forward of the carriage-axle, of a pressure-frame and a lifting-frame, said two frames having separate movements from each other, and both being located in rear of the axle-rod of the rake-teeth, as will be hereinafter described; sixth, in pivoting the levers of the lifting-bar and of the pressure-bar concentric with the axis of motion of the raketeeth,in combination with the arrangement of the pressure and lifting bars in rear of said axis of motion, and with the extending of the frames or levers of the said bars in front ofthe axle,softhat they may be operated by the feet of the driver, as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The carriage which supports the rake and the devices for operating itgconsists of an axletree, A, mounted upon two wheels, B B, and provided with a platform or stand-board, C C', for the driver. This platform C is some distance in advance of the axle and is sustained by means of the thillsD D. In order to keep the driver steady upon this stand-board when the machine is in motion, I erect a frame or guard, H, the posts of which may Vbe mortised into the platform or thills and suitably braced, so that the guard H will be rmly and substantially held in position. The position of this guard-rail is iu advance of the axle A, or at the forward part of the platform G, and sudicieutly raised abovethe latter to enable the driver to grasp it with his hands when standing erect. By this construction I am enabled to have the driver ride upon the machine. This being secured, it is important that the treadles for operating the elevating ,and depressing bars, hereinafter to be described, be so arranged as to be under the couvenient control of the driver, and to do this two levers, k2 k2, are pivoted to the sides ofthe thills a short distance in rear of the platform C, and extended back from their fulcra, so as to pass under short levers lc' c,which are pivoted concentrically with the motion of the raketeeth upon the rake-bar b, and to which a horizontal transverse pressure-bar, 7c, is attached, as shown in Figs. 1 and 2. This bar is in rear of the rake-bar, and extends across all the teeth of the rake, and restson top ofthe same, so that when pressure is put upon the two levers k2 k2 it will act uniformly upon the bar la, and consequently in like manner upon all ofthe foot is not sufficient to ykeep the raketeeth down to their raking position, thedriver can bring his entire weight to bear upon 'the rake-teeth by standing upon the board k3 and ing his weight to bear upon it whenever it is necessary. In order to more eiectually carry out this part of my inventiomthe rake-teeth are all independently pivoted to a horizontal bar,b,which extends across the machine, nearly over and in line with the axle-tree A, upon which this bar is supported at suitable points by means of eye-bearings or studs or posts c, as shown in Figs. 1 and 2 ofthe drawings. It will also be desirable to have the teeth made of spring steel or metal, so that they may be capable of yieldin g backward when they strike an obstruction in their path.

At an intermediate point between the ends of the rake-bar, and withinthe frame of standboard C, another frame, F, is arranged, and so pivoted on the rake-bar that its axis of motion is concentric with the axis of motion of ure-bar k, and it serves to support all theV teeth at a proper distance with respect to the ground, and also as a means for lifting all the teeth. It will be seen that when the frame F is moved in the plane indicated by red line y y in Fig. 2 the bar Gr will raise all the teeth,

` and thereby throw them up to a discharging position, and when the pressure is withdrawn from the foot-board of this frame all the teeth will return to their former raking position, which is represented I by black lines in Fig. 2. While the frame is intended asa means for elevating the teeth, it is not intended that it should interfere with the rising and falling movements of these teeth, either singly or to' gether, which movements are necessary to allow the teeth to free themselves of obstructions in their path, as well as to discharge the gathered hay. The frame F being pivoted to the rake-bar b concentric with the axis of mo-' b is made by simply passing the latter through the former, and thus the eye-bearings c c become the supportof them, as well as of the bar b. The pressure which is applied to the bar k through its own weight and that of the levers k k will not materially interfere with the rising of the teeth, although it will be suiicient to keep the teeth down during the operation of raking light swaths, and as the levers k k are not pivoted to the levers k2 k2 the whole series of teeth,or any one of them, may articulate at will, unless the weight of the driver is upon the levers kz k2, and in that event, if the resistance to be overcome is too great for the teeth to bear, the driver can instantly relieve the teeth by withdrawing his weight from the levers k2 k2, and, it' thought advisable, transferring it to the lifting contrivance F G, either of which expedients will have the effect of saving the teeth from injury. Thus it will be seen that it sfimportant to have the attendant on the machine, and the means for applying the pressure convenient for being operated from the stand-board or support, and so adapted to the machine that the attendant can have free use of his hands to manage his team. So,`also, lis it important, to this end, to have the lifting contrivance arranged convenient for being operated by the driver.

It will be observed that I use rake-teeth a, which terminate at their axial rod, and do not extend forward under a bar, as usual, in order to be depressed by such extended portions when it is desired to throw up their rear or raking ends. I am enabled to use ordinary rake-teeth, by reason of havingboth the pressnre-bar and the lifting-bar in rear of the axial rod of the teeth, and to bear upon the teeth \at points in rear of said axial rod.

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

1. A wheeled rake with a stand-board or platform, C, two sets of treadle-levers, two foot-boards, and'a lifting and a pressure bar, arranged and operating substantially in the manner and for the purpose described.

2. A wheeled rake with a hand-rail, astandboard, treadle-levers, foot-boards, and a lifting and a pressure bar, arranged and operating substantially in the manner and for. the purpose described. y

3. The arrangement of the pressure-bar k upon levers k It', which are independent, in their rising movements, ot' the treadle-levers k2 k2, but are dependent upon said levers, or their equivalent, in their depressing movement, ysubstantially as and for the purposes herein set forth.

4. The arrangement, in a wheeled rake, of independently-articulating teeth, a lifting-bar, a pressure-bar, and treadles, substantially in the manner and for the purposes herein described.
